Problems solved by technology

In addition to the above-mentioned two single forms of curtain body traction devices, there are also mechanical devices with dual functions of lifting and splitting, but the horizontal traction is realized by a traction machine. The large volume of the induction machine is not convenient to install on the horizontal guide rail

Embodiment Construction

[0008] As shown in Figure 2, the curtain body (not shown in the figure) is pulled by the steel wire ropes (2) on the front and rear sides of the horizontal guide rail (4) respectively, so that the left and right halves of the curtain body are separated, and the two head cars (15) are respectively consolidated On the wire rope (2) the suitable position that curtain body is overlapped, dolly (14) is emptied on the wire rope (2).

[0009] As shown in Figures 1a and 1b, the output end of the geared motor (5) is connected to the reel (6), the auxiliary support (10) uses UCP bearings to assist the reel (6), and the nut guide frame (7) is connected with the T-shaped thread The reel (6) is screwed together.

[0010] As shown in Figures 1a and 2, the horizontal guide wheel (8) is installed on the lower left side of the reel (6), near the left side of the nut guide frame (7) at the position of the reel (6); the wire rope ( 2) One end is fixed on the right end of the reel (6) and wound ...

Abstract

A drawing mechanism for both lifting and curtain of stage and opening the curtain from its center symmetrically is composed of two horizontal guide tracks and two drawing steel cables for opening the curtain from its center, two nut guide, a roller, two transverse cable guiding whells, steel cable, horizontal pulleys, and longitudinal cable guiding wheels.

Description

technical field [0001] The invention relates to a curtain body traction device in stage machinery. Background technique [0002] At present, the stage machinery curtain body traction mechanism adopts a single form of split type or lifting type. The former is to fix the horizontal guide rail above the stage opening, and the split traction wire rope goes around the horizontal pulley at one end of the horizontal guide rail and the vertical pulley at the other end of the horizontal guide rail. Then it is transmitted to the large curtain cabinet on the stage floor, where a driving machine drives the reel to wind the steel wire rope to reciprocate, so as to realize the function of pulling the curtain body to open and run. The lifting and lifting type is to hang the curtain body on the horizontal rod body, and hoist (or drag) the rod body to realize the function of lifting the curtain body. In addition to the above two single-form curtain body traction devices, there are also mech...
