Automatic rope-releasing device with follow-up drum

Abstract

The invention discloses an automatic rope arranging device of a following roller. The automatic rope arranging device comprises a fixing device, a motor, a screw rod, a roller and a spline shaft, wherein the spline shaft is fixedly connected with a motor shaft of the motor; the spline shaft is divided into two parts along the axial direction, wherein a spline groove is formed in the outer surface of the part near the motor shaft, and a smooth rod is arranged on the part far from the motor shaft; the screw rod is cylindrical and is sheathed on the outer circumferential surface of the smooth rod, and one end of the screw rod, which is far from the motor shaft, is fixedly arranged on the fixing device; the roller is sheathed on the outer circumferential surfaces of the spline shaft and the screw rod and is in spline connection with the spline shaft and in screw connection with the screw rod; the spline shaft and the roller are driven to rotate by the motor; and in the process that the spline shaft is rotated, the screw rod is kept unmovable, and the roller is moved on the screw rod along the axial direction. According to the automatic rope arranging device of the following roller, under the action of the motor, the roller is rotated and horizontally displaced at the same time, and steel wire ropes can be orderly and automatically arranged along with the rotation of the roller when the steel wire ropes are retracted and extended.

Description

technical field [0001] The invention relates to an automatic rope rowing device for a drum used in conjunction with a suspender in theaters and studios, in particular to an automatic rope rowing device for a follower drum. Background technique [0002] In stage performances, all performance theaters and studios are inseparable from hanging equipment. Hanging equipment is used to hang lamps under the equipment layer or at a height suitable for the performance, and the hanging lamps are adjusted according to the needs of the performance. to move. The hanging equipment includes motors, drums, wire ropes, etc. The motors are installed on the equipment layer, and the motors drive the drums to rotate to wind the wire ropes on the drums; during the winding process of the wire ropes, the wire ropes are on the drums through pulleys, rope guide wheels, etc. The sequence of rolling in and out drives the hanging lamps up and down, or moves the hanging lamps according to actual needs. ...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, the hanging equipment mainly relies on changing the pulley block to arrange the ropes, or relying on the mutual extrusion of the steel wire ropes to arrange the ropes freely. Although this can also achieve the effect of the rope arrangement, it is prone to messy ropes, and the reliability is not high. The number of layers is not easy, and sometimes the angle between the wire rope and the drum is too large, which will lead to uneven arrangement of the wire rope and inconsistent degree of tightness

In addition, because the existing hanging equipment needs a certain working area on the equipment layer, for various studios and theaters, it is necessary to reserve a certain working space on the equipment layer, and this is for some small studios. there are certain difficulties
