Description

Technical Field

[0001] The utility model relates to the technical field of cable retracting and releasing of stage lifting mechanical equipment, in particular to a cable retracting and releasing device of stage lifting mechanical equipment. Background Art

[0002] Lifting platforms are frequently used performance tools in stage performances. At the same time, with the increase in the variety of performances and the diversification of program types, the requirements for lifting platforms are also constantly increasing. In order to ensure the safety of lifting machinery and equipment, it is necessary to install a cable retractor. The cable retractor of stage lifting machinery and equipment is a device specifically used to manage, store and protect equipment cables.

[0003] For example, a cable retracting and releasing device for a stage lifting mechanical equipment disclosed in Chinese patent CN217376878U can prevent the cable from being damaged due to friction between the cable and the side edge of the opening of the blocking ring during the rotation of the turntable by setting a wire tube on one side of the blocking ring of the tray. The wire locking disk set under the turntable replaces the saw teeth originally provided on the turntable, thereby solving the defect that the saw teeth easily get the cable stuck during the rotation of the turntable. The travel switch set can stop the winding disk in time, thereby enhancing the flexibility of controlling the winding device.

[0004] Although this structure can prevent the cable surface from being damaged when it is rolled up, it can only wind the cable up and down, but cannot ensure that the cable is tightly wound layer by layer, resulting in a poor cable storage effect. Therefore, we propose a cable retracting device for stage lifting mechanical equipment that can tightly wind the cable layer by layer to improve the cable reeling effect. Utility Model Content

Under the restriction of the limit bar, when the reciprocating screw rotates, the sleeve block can be driven to reciprocate on the outer wall of the reciprocating screw.

[0010] Preferably, the outer wall of the slide plate is slidably arranged with the inner wall of the sleeve frame, and the slide plate is rotationally connected to the end of the pressure roller, so that under the elastic restriction of the first spring, the pressure roller is in close contact with the cable wound on the outer wall of the winding roller to improve the cable storage effect.

[0011] Preferably, the slide column is slidably arranged with the outer wall of the limit rod, and the slide column is rotationally connected with the end of the auxiliary roller, under the support of which, the second spring clamps and transports the cable through the auxiliary roller to avoid contact and friction between the inner wall of the guide ring and the cable.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The cable retracting and releasing device of the stage lifting mechanical equipment is composed of a retracting and releasing assembly as one of its components. When the cable needs to be retracted, it will pass through the guide ring and be wound around the outer wall of the reel. At this time, the motor is started, and the reel fixedly installed at its output end starts to rotate. The reel reels the cable.

Since one end of the first spring is fixedly installed on the inner wall of the frame and the end away from the inner wall of the frame is fixedly installed on the slide, the slide is slidably arranged on the inner wall of the frame. Under the support of the pressure roller, the cable is tightly wound layer by layer.

When the cable needs to be stored, it is passed through the inside of the guide ring and placed between the auxiliary rollers. Under the restriction of the sponge board fixedly installed on the inner wall of the guide ring, the dust on the surface of the cable can be cleaned first, and then the cable can be wound by the winding roller. When the cable is supported by four auxiliary rollers, it can be stably transported to the inside of the storage box to avoid the inner wall of the guide ring from wearing the cable surface. Under the restriction of the elasticity of the second spring sleeved on the outer wall of the limit rod, the auxiliary roller can clamp and transport the cable. BRIEF DESCRIPTION OF THE DRAWINGS
