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 drawings and embodiments.

[0015] Such as Figure 1 As shown, two hoisting drive devices 1, 1'are respectively installed on the flyovers on opposite sides of the stage, the I-shaped horizontal rail 3 is fixed under the top of the stage grid, the horizontal trolley 4 is installed on the horizontal rail 4, and the corner pulley 2 It is fixed at both ends of the horizontal guide rail 4 and is located above the driving device. The pulley hook 6 is suspended on both sides by the suspension rope 5 through its movable pulleys. The rope 5 enters from the center of the horizontal trolley 4 and then goes around the pulleys 4.2 on it, and then runs horizontally to both sides of the stage, and then goes around each other. The corner pulley 2 sags and enters the reel 1.4 of the respective driving device to be wound and fixed.

[0016] As shown in Figure 2 and Figure 3, the frequency conversion brake motor 1.1,...

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 present invention mainly relates to stage installations. Background technique [0002] The well-known theater lifting and translating manned aircraft all use a set of main driving machines for lifting and driving; a set of auxiliary driving machines are used for traction and translation movement, and the main and auxiliary driving machines operate independently. In most cases, the operation of the main and auxiliary drives are alternate, and their total installed capacity cannot be fully utilized. Moreover, the lifting drive adopts a duplex structure, that is, the rope running speed of the driving machine is twice the speed of the hook lifting speed, which causes the driving machine to run at a high speed, causing a lot of noise, and the wire rope is easier to laterally vibrate. Furthermore, a main driving machine bears the lifting load, and it is not easy to eliminate the fault in time, and the probability of the fault is relatively high. [0003] Fore...
