Auxiliary hoisting device for bridge construction

Abstract

The invention provides an auxiliary hoisting device for bridge construction, which includes a connecting frame and a hoisting frame; the inside of the base is a hollow structure, and a plane bearing is installed inside the base; the bottom of the main frame body is connected in the base, and the main frame body A winch is fixedly installed on the outside, and the winch is connected to the external control circuit; the screw rod is connected to the top of the main frame body in rotation, and one end of the screw rod is connected to the transmission belt; the adjustment motor is installed on the top of the main frame body, and the adjustment motor is connected to the external control circuit Connected; the present invention can drive the internal worm of the connecting frame to rotate through the transmission motor according to the placement angle of the hoisting items, and the worm further drives the worm wheel to rotate, so that the worm wheel drives the hoisting frame to rotate, and the hoisting frame drives the hoisting items to rotate, which is better for hoisting Items need to be placed at different angles, and after the hoisting frame is rotated and adjusted, the hoisting frame is fixed through the self-locking characteristics of the worm and worm gear to ensure the stability of the hoisting frame during use.

Description

Technical field [0001] The present invention belongs to the technical field of bridge construction, and more particularly to a auxiliary lifting device for bridge construction. Background technique [0002] The bridge refers to a building that is built by the road, which is built in the sea of ​​Jianghe Lake, which makes the vehicle pedestrian, etc., the bridge is generally composed of the upper structure, the lower structure, and the accessory structure, and the upper structure is mainly Bridge cross-structure and support system; lower structure includes bridge, bridge piers, and foundation; attached structures refer to bridge head panels, tapered slides, shields, flow through the project, etc .; often use in the construction of the bridge. Auxiliary devices to improve the construction progress of the bridge. [0003] The auxiliary lifting device for bridge construction can be referring to CN108862058B, which mainly includes a support post, and a support block is fixedly mounted...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the above-mentioned technical problems, the present invention provides an auxiliary hoisting device for bridge construction, to solve the problem that the existing auxiliary hoisting device for bridge construction cannot effectively respond to the requirements of the placement angle of the hoisted items when using the existing similar auxiliary hoisting device for bridge construction. To adjust the rotation, it is usually necessary to manually approach the hanging item to adjust the angle manually. The risk factor is poor, and the hanging item is prone to fall off, which will injure the construction personnel and increase the construction safety risk.
