[0022] The support and guide frame 5-3 is fixed via the swivel plate 5-17 to a rotary disk of the rotary platform 5-2; the swivel plate 5-17 is provided with rollers 5-7 that fit with the guide rails 5-8 at positions corresponding to the guide rails 5-8; the rollers 5-7 provides a support function for the support and guide frame 5-3.

[0023] A push rod right support angle steel piece 5-13 is fixedly connected to the left end of the left angle steel piece 5-14, a push rod left support angle steel piece 5-11 is parallelly arranged at the left side of the push rod right support angle steel piece 5-13, the front and rear ends of the push rod left support angle steel piece 5-11 and push rod right support angle steel piece 5-13 are fixedly connected via a front angle steel piece 5-12 and a rear angle steel piece 5-10 arranged in parallel to each other.

[0024] A hinged base 5-5 is fixedly connected above the push rod left support angle steel piece 5-11, a support base 5-4 is fixedly connected above the push rod right support angle steel piece 5-13, the hinged base 5-5 is hinged to the left end of an electric push rod 5-6, the support base 5-4 is used for fixing the middle part of the electric push rod 5-6, a counterweight device 5-9 is connected to the right end of the electric push rod 5-6, and the counterweight device 5-9 can work with the two counterweight guide rails 5-15 to move in an extending/retracting direction of the electric push rod 5-6.

[0025] The counterweight device 5-9 can be counterweight blocks. In the present invention, to reduce the friction of the counterweight device 5-9 against the counterweight guide rails 5-15, the counterweight device 5-9 comprises a counterweight frame 5-19 and counterweight blocks 5-18 arranged on the counterweight frame 5-19, at least four counterweight wheels 5-20 arranged around the bottom of the counterweight frame 5-19 at positions corresponding to the two counterweight guide rails 5-15. Thus, the counterweight device 5-9 can move smoothly, and thereby any eccentric load of the platform can be eliminated quickly.

[0026] The suspension platform 4 is a circular, also can be a square; circular shape is preferred in the present invention. The rotary platform 5-2 is arranged at the center of circle of the suspension platform 4, and the guide rail 5-8 is arranged around the outer rim of the suspension platform 4.

[0027] In actual application, the suspension platform 4 may be configured into a double-layer truss structure, wherein, the upper layer is used to bear persons and cargo, the eccentric load adjusting mechanism 5 is arranged on the lower layer. Of course, the suspension platform 4 may be configured into a hollow structure, with the eccentric load adjusting mechanism 5 disposed in a cavity in the suspension platform 4. Alternatively, the eccentric load adjusting mechanism 5 may be disposed on the top surface of the suspension platform 4, and then the suspension platform 4 is covered with a cover body, the top part of which is configured to bear cargo.

[0028] When an eccentric load of the suspension platform 4 occurs, the rotary platform 5-2 is driven by the servo motor 5-1 to rotate, and thereby the support and guide frame 5-3 is driven to move in a direction opposite to the eccentric load; then, the counterweight device 5-9 is driven to move in the length direction of the support and guide frame 5-3 as the electric push rod 5-6 extends/retracts, so that the eccentric load of the suspension platform 4 is eliminated.

[0029] An eccentric load adjusting method for a suspension platform, comprising the following steps:

[0030] step 1: arranging four rope winding devices 1 in the same horizontal plane, wherein each of rope winding devices 1 is wound with a steel wire rope 2 respectively, connecting each of the four steel wire ropes 2 via a tension sensor 3 to the suspension platform 4 respectively, and assembling the eccentric load adjusting mechanism 4 on the suspension platform 4;

[0031] step 2: when an eccentric load of the suspension platform 4 occurs, obtaining tension data by the tension sensors 3, performing tension analysis and ascertaining the magnitude and position of the eccentric load under a moment balance principle by means of a controller connected with the tension sensors 3, and controlling a servo motor 5-1 by the controller to drive the rotary platform 5-2 to rotate, and thereby driving the support and guide frame 5-3 to rotate to an angle corresponding to a direction opposite to the eccentric load, and then moving the counterweight device 5-9 on the counterweight guide rails 5-15 by a corresponding distance by the electric push rod 5-6, so as to eliminate the eccentric load of the platform.

[0032] With the method, the suspension platform can operate safely and stably, and can operate normally in a harsher and more complex environment.
