Guide rail rope deflection inhibition mechanism and method for parallel soft cable suspension system

Abstract

A guide rail rope deflection inhibition mechanism and method for a parallel soft cable suspension system in ultradeep vertical shaft construction. The guide rail rope deflection inhibition mechanism comprises a T-shaped installation support base, a rotating frame, a hydraulic support rod, and a chuck. The T-shaped installation support base comprises a vertical support rod and a horizontal support rod. The hydraulic support rod comprises an upper hydraulic support rod and a lower hydraulic support rod. The rotating frame comprises an upper Y-shaped frame and a lower Y-shaped frame. The chuck comprises an upper chuck and a lower chuck. The guide rail rope deflection inhibition method treats two guide rail rope deflection inhibition mechanisms as one group, and arranges at least two groups along the vertical direction on the shaft wall. While guaranteeing the smooth sliding of a direction guiding frame, the freedom of the guide rail rope part is restrained by the chuck, thereby enhancing the stability and safety of hoisting containers.

DETAILED DESCRIPTION OF THE EMBODIMENTS

(8) Hereunder the present invention will be further detailed with reference to the accompanying drawings.

(9) As shown in FIG. 1 and FIG. 2, the guide rail rope deflection inhibiting mechanism for a parallel flexible cable suspension system according to the present invention comprises a T-shaped mounting support 1, a rotary frame 2, a hydraulic supporting rod 3 and a chuck 4.

(10) The T-shaped mounting support 1 comprises a longitudinal supporting rod and a transverse supporting rod, the longitudinal supporting rod is fixed on the shaft wall 8, and one end of the transverse supporting rod is fixed to the center of the longitudinal supporting rod. The hydraulic supporting rod 3 comprises an upper hydraulic supporting rod 3-1 and a lower hydraulic supporting rod 3-2, one end of the upper hydraulic supporting rod 3-1 is hinged to the upper end (end A in the figures) of the longitudinal supporting rod, and one end of the lower hydraulic supporting rod 3-2 is hinged to the lower end (end B in the figures) of the longitudinal supporting rod. The rotary frame 2 comprises an upper Y-shaped bracket 2-1 and a lower Y-shaped bracket 2-2, and the upper Y-shaped bracket 2-1 and lower Y-shaped bracket 2-2 are in the same structure. One end (end C in the figures) of the upper Y-shaped bracket 2-1 is hinged to the other end of the upper hydraulic supporting rod 3-1, one end (end D in the figures) of the lower Y-shaped bracket 2-2 is hinged to the other end of the lower hydraulic supporting rod 3-2, the other end of the upper Y-shaped bracket 2-1 is fixed to the other end of the lower Y-shaped bracket 2-2 and hinged to the other end (end E in the figures) of the transverse supporting rod; a third end of the upper Y-shaped bracket 2-1 and a third end of the lower Y-shaped bracket 2-2 are provided with a hollow steel part 2-3 respectively, the hollow steel part 2-3 has a bolt hole 2-5, and a fastening bolt 2-4 is arranged in the bolt hole 2-5. The chuck 4 comprises an upper chuck 4-1 and a lower chuck 4-2, and both the upper chuck 4-1 and the lower chuck 4-2 comprise a a V-shaped chuck 4-3 and a round steel part 4-4, the V-shaped chuck 4-3 is arranged with a snap groove that can embrace the guide rail rope 5, one end of the round steel part 4-4 is fixed to the V-shaped chuck 4-3, and the other end of the round steel part 4-4 extends into the tube of the hollow steel part 2-3 and is fixed by a fastening bolt 2-4, and thereby the upper chuck 4-1 and lower chuck 4-2 are fixed to the third end of the upper Y-shaped bracket 2-1 and the third end of the lower Y-shaped bracket 2-2 respectively, so that the rotary frame 2 and the chuck 4 are connected together. During use, the length of the round steel part 4-4 extending into the hollow steel tube 2-3 can be adjusted to regulate the extension length of the upper chuck 4-1 and the lower chuck 4-2, so as to secure the guide rail rope 5.

(11) As shown in FIG. 4, when the rotary frame 2 rotates around the other end of the transverse supporting rod to a position where the lower chuck 4-2 is in a horizontal state, the upper chuck 4-1 will be in an up-tilting state. At this point, both the upper hydraulic supporting rod 3-1 and the lower hydraulic supporting rod 3-2 are in maximum extension state; in addition, since the hydraulic supporting rod 3 provides persistent and steady pushing force, the moment of resistance to the other end of the transverse supporting rod of the T-shaped mounting support 1 is negative (here, the moment in a counter-clockwise direction is defined as positive); therefore, the rotary frame 2 cannot rotate, and the guide rail rope deflection inhibiting mechanism is in a stable state. As shown in FIG. 5, when the rotary frame 2 rotates around the other end of the transverse supporting rod to a position where the upper end of the longitudinal supporting rod, one end of the upper Y-shaped bracket 2-1, and the other end of the Y-shaped bracket 2-1 are in the same line, the lower end of the longitudinal supporting rod, one end of the lower Y-shaped bracket 2-2, and the other end of the lower Y-shaped bracket 2-2 will be also in the same line. At this point, the moment of resistance of the hydraulic supporting rod 3 to the other end of the transverse supporting rod of the T-shaped mounting support 1 is zero. As shown in FIG. 6, when the rotary frame 2 rotates around the other end of the transverse supporting rod to a position where the upper chuck 4-1 is in a horizontal state, the lower chuck 4-2 will be in an up-tilting state. At this point, both the upper hydraulic supporting rod 3-1 and the lower hydraulic supporting rod 3-2 are in maximum extension state; in addition, since the hydraulic supporting rod 3 provides persistent and steady pushing force, the moment of resistance to the other end of the transverse supporting rod of the T-shaped mounting support 1 is positive; therefore, the rotary frame 2 cannot rotate, and the guide rail rope deflection inhibiting mechanism is in a stable state.

(12) As shown in FIG. 3, the guide rail rope deflection inhibiting method for a parallel flexible cable suspension system according to the present invention is characterized in that every two guide rail rope deflection inhibiting mechanisms are arranged into a group, and at least two groups of the guide rail rope deflection inhibiting mechanisms are arranged on the shaft wall 8 in a vertical direction. In this embodiment, two groups of guide rail rope deflection inhibiting mechanisms are provided, and they are arranged on the lower part (or middle part) of the guide rail rope 5, where the lateral rigidity is lower; the spacing between the two groups of guide rail rope deflection inhibiting mechanisms is 5-20 m.

(13) When the lifting container 7 is to run downward, the rotary frames 2 of the two groups of guide rail rope deflection inhibiting mechanisms are rotated to a position where the lower chucks 4-2 are in a horizontal state, and the guide rail rope 5 are secured by the lower chucks 4-2 of the two groups of guide rail rope deflection inhibiting mechanisms; at this point, the upper chucks 4-1 of the two groups of guide rail rope deflection inhibiting mechanisms are in a tilting state that permits the guide frame 6 to pass through.

(14) When the guide frame 6 moves downward and comes into contact with the lower chuck 4-2 of the first group of guide rail rope deflection inhibiting mechanisms, the guide frame 6 will overcome the moment of resistance produced by the hydraulic supporting rod 3 of the first group of guide rail rope deflection inhibiting mechanisms by gravity, and push the lower chuck 4-2 of the first group of guide rail rope deflection inhibiting mechanisms to retract and deflect downward gradually, and thereby drive the rotary frame 2 of the first group of guide rail rope deflection inhibiting mechanisms to rotate; when the guide frame 6 is separated from the lower chuck 4-2 of the first group of guide rail rope deflection inhibiting mechanisms, the rotary frame 2 of the first group of guide rail rope deflection inhibiting mechanisms will be rotated to a position where the upper chuck 4-1 is in horizontal state, and the guide rail rope 5 will be secured by the upper chuck 4-1 of the first group of guide rail rope deflection inhibiting mechanisms. In that process, the guide frame 6 runs downward smoothly, and passes through the first group of guide rail rope deflection inhibiting mechanisms.

(15) When the guide frame 6 moves downward to a position between the first group of guide rail rope deflection inhibiting mechanisms and the second group of guide rail rope deflection inhibiting mechanisms, the guide rail rope 5 is secured by the upper chuck 4-1 of the first group of guide rail rope deflection inhibiting mechanisms and the lower chuck 4-2 of the second group of guide rail rope deflection inhibiting mechanisms.

(16) When the guide frame 6 moves downward and comes into contact with the lower chuck 4-2 of the second group of guide rail rope deflection inhibiting mechanisms, the guide frame 6 will overcome the moment of resistance produced by the hydraulic supporting rod 3 of the second group of guide rail rope deflection inhibiting mechanisms by gravity, and will push the lower chuck 4-2 of the second group of guide rail rope deflection inhibiting mechanisms to retract and deflect downward gradually, and thereby drive the rotary frame 2 of the second group of guide rail rope deflection inhibiting mechanisms to rotate; when the guide frame 6 is separated from the lower chuck 4-2 of the second group of guide rail rope deflection inhibiting mechanisms, the rotary frame 2 of the second group of guide rail rope deflection inhibiting mechanisms will be rotated to a position where the upper chuck 4-1 is in horizontal state, and the guide rail rope 5 will be secured by the upper chucks 4-1 of the second group of guide rail rope deflection inhibiting mechanisms. In that process, the guide frame 6 runs downward smoothly, and passes through the second group of guide rail rope deflection inhibiting mechanisms.

(17) After the guide frame 6 passes through the second group of guide rail rope deflection inhibiting mechanisms, the guide rail rope 5 will be secured by the upper chucks 4-1 of the two groups of guide rail rope deflection inhibiting mechanisms.

(18) Likewise, when the lifting container 7 runs upward, the rotary frames 2 of the two groups of guide rail rope deflection inhibiting mechanisms are rotated to a position where the upper chucks 4-1 are in a horizontal state, and the guide rail rope 5 is secured by the upper chucks 4-1 of the two groups of guide rail rope deflection inhibiting mechanisms; at this point, the lower chucks 4-1 of the two groups of guide rail rope deflection inhibiting mechanisms are in a tilting state that permits the guide frame 6 to pass through.

(19) When the guide frame 6 moves upward and comes into contact with the upper chuck 4-1 of the second group of guide rail rope deflection inhibiting mechanisms, the guide frame 6 will overcome the moment of resistance produced by the hydraulic supporting rod 3 of the second group of guide rail rope deflection inhibiting mechanisms by the upward pushing force provided by the lifting container 7, and will push the upper chuck 4-1 of the second group of guide rail rope deflection inhibiting mechanisms to retract and deflect upward gradually, and thereby drive the rotary frame 2 of the second group of guide rail rope deflection inhibiting mechanisms to rotate; when the guide frame 6 is separated from the upper chuck 4-1 of the second group of guide rail rope deflection inhibiting mechanisms, the rotary frame 2 of the second group of guide rail rope deflection inhibiting mechanisms will be rotated to a position where the lower chuck 4-2 is in horizontal state, and the guide rail rope 5 will be secured by the lower chuck 4-2 of the second group of guide rail rope deflection inhibiting mechanisms. In that process, the guide frame 6 runs upward smoothly, and passes through the second group of guide rail rope deflection inhibiting mechanisms.

(20) When the guide frame 6 moves upward to a position between the second group of guide rail rope deflection inhibiting mechanisms and the first group of guide rail rope deflection inhibiting mechanisms, the guide rail rope 5 will be secured by the lower chuck 4-2 of the second group of guide rail rope deflection inhibiting mechanisms and the upper chuck 4-1 of the first group of guide rail rope deflection inhibiting mechanisms.

(21) When the guide frame 6 moves upward and comes into contact with the upper chuck 4-1 of the first group of guide rail rope deflection inhibiting mechanisms, the guide frame 6 will overcome the moment of resistance produced by the hydraulic supporting rod 3 of the first group of guide rail rope deflection inhibiting mechanisms by the upward pushing force provided by the lifting container 7, and push the upper chuck 4-1 of the first group of guide rail rope deflection inhibiting mechanisms to retract and deflect upward gradually, and thereby drive the rotary frame 2 of the first group of guide rail rope deflection inhibiting mechanisms to rotate; when the guide frame 6 is separated from the upper chuck 4-2 of the first group of guide rail rope deflection inhibiting mechanisms, the rotary frame 2 of the first group of guide rail rope deflection inhibiting mechanisms will rotate to a position where the lower chuck 4-1 is in horizontal state, and the guide rail rope 5 will be secured by the lower chuck 4-2 of the first group of guide rail rope deflection inhibiting mechanisms. In that process, the guide frame 6 runs upward smoothly, and passes through the first group of guide rail rope deflection inhibiting mechanisms.

(22) After the guide frame 6 passes through the first group of guide rail rope deflection inhibiting mechanisms, the guide rail rope 5 will be secured by the lower chucks 4-2 of the two groups of guide rail rope deflection inhibiting mechanisms.
