Problems solved by technology

In most cases, the operation of the main and auxiliary driving machines is alternate, and the total installed capacity cannot be fully utilized
Moreover, the lifting drive adopts a duplex structure, that is, the running speed of the driving machine around the rope is twice that of the lifting speed of the hook, resulting in high running speed of the driving machine, loud noise, and easier lateral vibration of the steel wire rope.
Furthermore, a main driving machine bears the lifting load, and it is difficult to eliminate it in time when a failure occurs, and the probability of failure is relatively high.
[0003] Foreign manufacturers have an improved structure in which a lifting drive machine is equipped with two reels, and a hook is suspended by two steel wire ropes at the same time. higher probability

Embodiment Construction

[0014] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0015] As shown in Figure 1, two winch-type driving devices 1, 1' are respectively installed on the flyovers on opposite sides of the stage, the I-shaped horizontal guide rail 3 is fixed under the top of the stage grid, and the horizontal trolley 4 is installed on the horizontal guide rail 3 , The corner pulley 2 is fixed on both ends of the horizontal guide rail 3 and is located above the driving device. The pulley hook 6 is suspended on both sides by the suspension rope 5 through its movable pulley. The rope 5 enters from the center of the horizontal trolley 4 and then bypasses the pulley 4.2 on it respectively, and then moves horizontally to both sides of the stage, and then bypasses the respective The corner pulleys 2 are drooping, and the drums 1.4 entering the respective drives are wound and fixed.

[0016] As shown in Fig. 2 and Fig. 3, the freq...

Abstract

The lifting and translating driving system for manned stage frame has separate lifting driver and translating driver and thus failure probability. It has horizontal guide track on the ceiling, horizontal bogie on the horizontal guide track, and rope from the driver connected to the flying frame through the pulley on the horizontal bogie. It features that two drivers are installed separately onto two overbridges and the ropes from the two drivers are made to pass through the pulley on the horizontal bogie and connect to the flying frame. The present invention with double drivers has the advantages of full use of driving system capacity, easy realization of computerized program control, low failure rate, etc.

Description

technical field [0001] The invention relates to a lift-and-translate man-carrier, in particular to a driving device for a lift-and-translate man-carrier specially used in theaters. Background technique [0002] Known manned aerial vehicles for lift and translation in theaters all adopt a set of main driving machines for lifting and driving; In most cases, the operation of the main and auxiliary driving machines is alternate, and the total installed capacity cannot be fully utilized. Moreover, the lifting drive adopts a double structure, that is, the driving machine's winding speed is twice that of the hook lifting speed, resulting in high driving speed, loud noise, and easier lateral vibration of the wire rope. Furthermore, a main driving machine bears the lifting load, and it is difficult to eliminate it in time when a failure occurs, and the probability of failure is relatively high. [0003] Foreign manufacturers have an improved structure in which a lifting drive machi...
