AI Technical Summary

Technical Problem

The existing auxiliary lifting device for tunnel cable maintenance cannot lift the two cables laid side by side at the same time, and the aperture of the cladding structure cannot be flexibly adjusted according to the cable diameter, and the applicability is low.

Method used

A bracket including rotating a bracket mounted on the side of the lifting plate is designed, and a sliding assembly is provided on the top of the bracket. The sliding assembly drives the lead screw to rotate through the active bevel gear and the driven bevel gear to realize the lateral sliding of the mounting plate. The U-shaped fixing seat and the mobile clamp assembly are used to fix and clamp a cable, and the U-shaped movable seat and the mobile clamp assembly are used to fix and clamp another cable. Through the cooperation of the magnet slider and the electromagnet, the spacing between the U-shaped fixed seat and the U-shaped movable seat is adjusted to adapt to different cable spacing. The fan ring and the roller combine to drive the clamping ring to slide longitudinally, and the height of the clamping ring is adjusted according to the cable diameter.

Benefits of technology

The two cables laid side by side are realized simultaneously, which improves the efficiency and safety of maintenance work, and flexibly adjusts the aperture of the clamping structure according to the cable diameter, thereby improving the applicability of the device.

Abstract

The invention discloses auxiliary lifting equipment for tunnel cable maintenance, and relates to the field of tunnel cable maintenance, the auxiliary lifting equipment comprises a bracket rotatably mounted on one side of a lifting plate, the top of the bracket is provided with a sliding assembly which is fixedly connected with a mounting plate and drives the mounting plate to transversely slide on the top of the bracket, and one end of the top of the mounting plate is fixedly provided with a U-shaped fixing seat; a U-shaped movable seat is slidably mounted in the center of the top of the mounting plate, a magnet sliding block is fixedly arranged at the bottom of the U-shaped movable seat, a third sliding groove matched with the magnet sliding block in shape is formed in the top of the mounting plate, and the magnet sliding block is located in the third sliding groove and slides transversely. And an electromagnet I and an electromagnet II are fixedly mounted at the positions, located on the two sides of the sliding groove III, in the mounting plate correspondingly. According to the device, two cables can be lifted at the same time, the tunnel cables can be better overhauled, the effect of stably lifting the cables is achieved, the movable clamping plate assembly can fix the cables with different diameters, and the applicability of the device is improved.
