Take-up and pay-off device and method for exhibition hall

Abstract

The invention relates to a take-up and pay-off device and method for an exhibition hall. A rotating shaft comprises a small-diameter part at the middle section and large-diameter parts at the two ends, a pay-off assembly comprises multiple sections of pay-off cylinders arranged in the axial direction, and a side plate of each section of pay-off cylinder is supported on a supporting round wheel; the supporting round wheels are installed on a supporting plate, the supporting plate is fixed on a frame base, and the rotating shaft penetrates through inner holes of the pay-off assembly; the inner holes at the two ends of the pay-off assembly are matched with the large-diameter parts at the two ends of the rotating shaft, and the end part of the rotating shaft is rotationally supported on the frame base; a joint part is arranged in the middle of an inner hole of each section of pay-off cylinder, each joint part is provided with a U-shaped groove in the axial direction, and the multiple U-shaped grooves are located in the same linear direction in the axial direction; and the small-diameter part of the rotating shaft is convexly provided with convex blocks matched with the U-shaped groovesof all the sections, and the multiple convex blocks are located in the same straight line direction in the axial direction. When one of the convex blocks is matched with the U-shaped groove of one pay-off cylinder, the other convex blocks are not matched with the U-shaped grooves of the pay-off cylinders; and the position of a moving rotating disc is adjusted, and the working states of differentpay-off cylinders are rapidly switched.

Description

technical field [0001] The invention relates to a wire retracting and releasing device for an exhibition hall and a method thereof. Background technique [0002] At present, the multimedia equipment and lighting devices in the exhibition hall require a large number of wires to transmit electric energy and communication cables to transmit signals. During the layout process, the disordered lines will be entangled with each other, which increases the probability of wrong wiring and causes the equipment to not work normally; at the same time, the process of pulling the lines will also cause deformation or breakage, affecting normal use. At present, the take-up and pay-off setting only has one bobbin or a simple superposition of multiple bobbins, which has a single function and takes up a lot of space. When there are many lines and the lengths of the lines are not the same, it cannot be adjusted quickly. Contents of the invention [0003] The object of the present invention i...
