Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) The disclosure will now be described with reference to the annexed drawings, which illustrate a non-limiting example of embodiment thereof, and in which:

(2) FIG. 1 illustrates, partially and in side elevation, one example embodiment of a belt-conveying aerial system provided according to the teachings of the present disclosure;

(3) FIG. 2 is a cross section according to the line of FIG. 1; and

(4) FIG. 3 is a perspective view of a detail of FIGS. 1 and 2.

DETAILED DESCRIPTION

(5) Referring row to the example embodiments of the present disclosure illustrated in FIGS. 1 to 3, in FIGS. 1 and 2, designated, as a whole, by 1 is a belt-conveying aerial system comprising a pair of top fixed load-bearing ropes 2 stretched between two anchorage points (not visible in the attached figures) in positions parallel to one another and set at a distance apart from one another in a transverse direction.

(6) The system then comprises a pair of bottom fixed load-bearing ropes 3, which are also stretched between two fixed points (not visible in the attached figures) and are each set parallel to and underneath a respective top load-bearing rope 2 and at a distance from one another, conveniently the same as the distance between the top load-bearing ropes 2.

(7) The system 1 further comprises a belt conveyor 4 (not described in detail) which extends between the load-bearing ropes 2, 3. The belt conveyor 4 comprises a plurality of modules 5 (just one of which is visible in the attached drawings). The modules 5 are aligned with respect to one another along the load-bearing ropes 2, 3 in order to support and guide a respective stretch of a conveyor belt 6 (FIG. 2) having a forward branch 7 and a return branch 8, which are mobile on supporting idle rollers 10 and 11 carried by the frames 13 of the aforesaid modules 5.

(8) Each frame 13 is then provided, for each load-bearing rope 2, 3, with a respective row 14 of jaws 15 for attachment to the corresponding load-bearing rope 2, 3 (not described in detail).

(9) Once again with reference to FIGS. 1 and 2 and, in particular to FIG. 3, the system 1 further comprises a vehicle 18 configured to install the modules 5 on the load-bearing ropes 2, 3, The installation vehicle 18 comprises a top supporting carriage 19 set above the top load-bearing ropes 2 and mobile in opposite directions on the top load-bearing ropes 2 themselves in a longitudinal direction 20. The carriage 19 comprises, for each top load-bearing rope 2, a longitudinal member 21 parallel to the load-bearing ropes 2, 3 and a pair of wheels 23, which are set one upstream and the other downstream of the corresponding module 5 and are hinged to opposite terminal portions of the corresponding longitudinal member 21 so as to turn about respective axes 23A orthogonal to the load-bearing ropes 2, 3.

(10) The carriage 19 carries, coupled to the longitudinal members 21, an intermediate portion of a cylindrical beam 24 comprising two opposed terminal portions 25 that project in cantilever fashion beyond the carriage 19. Fixedly connected to the free end of each terminal portion 25 is a top terminal portion of a rigid upright 27, coupled to a bottom terminal portion of which is a shuttle 28 for the staff responsible for installing the modules 5, which has a treading platform 29 that is horizontal irrespective of the inclination of the load-bearing ropes 2, 3 (as may be seen in FIG. 3).

(11) Once again with reference to FIG. 3, the uprights 27 and the corresponding shuttles 28 are set on opposite lateral sides of the load-bearing ropes 2, 3 and of the corresponding module 5 that is being installed.

(12) Once again with reference to the attached figures, the installation vehicle 18 further comprises, for each bottom load-bearing rope 3, a pair of wheels 30, which are set one upstream and the other downstream of the module 5 in the longitudinal direction and are rotatable in contact with the respective bottom load-bearing rope 3. Each wheel 30 is carried by a corresponding upright 31 that keeps the wheel at a fixed distance from the carriage 19 and from an overlying wheel 23 and has a top terminal portion 32 fixedly connected to the corresponding longitudinal member 21 in the proximity of the axis 23A, and a fork-shaped load-bearing bottom terminal portion 33 hinged to the corresponding wheel 30 in a rotatable way about an axis 34 of its own parallel to the axes 23A. As may be seen once again from the attached figures, the axes 23A and 34 are intersected by a common line A orthogonal to the load-bearing ropes 2, 3 and to the axes 23A and 34,

(13) From the foregoing, it emerges that the structure of the carriage 19 and, in particular, the fact that carriage comprises two sets of wheels arranged at a given or designated and fixed vertical distance from one another keeps the top load-bearing ropes at a fixed and predefined distance from the bottom load-bearing ropes irrespective of the load applied on the carriage 19, and this enables a relatively easy and relatively fast coupling of the jaws 15 to the respective load-bearing ropes 2, 3, without the need to use dedicated installation equipment.

(14) The scope of the present disclosure is defined by the claims, which cover variants that are not explicitly described and equivalent embodiments. As such, changes may be made to the embodiments of the present disclosure described with reference to the attached drawings without, however, departing from the protective scope of the accompanying Claims. Accordingly, various changes and modifications to the presently disclosed embodiments will be apparent to those skilled in the art. Such changes and modifications can be made without departing from the spirit and scope of the present subject matter and without diminishing its intended advantages. It is therefore intended that such changes and modifications be covered by the appended claims.
