Lifting device for highway bridge

Abstract

The invention discloses a hoisting device for highway bridges, which comprises a hoisting locomotive body, a balance plate, a beam lamp mounting frame and a second lifting rod. There is a rear bucket, a stable seat is arranged on the upper end of the rear bucket, a servo motor is arranged inside the stable seat, and a mounting seat is arranged on the upper end of the turntable. The invention has a scientific and reasonable structure, is safe and convenient to use, is provided with a beam lamp, and the beam lamp emits a beam to the object that needs to be lifted, which can ensure that the falling route of the hook is just above the object that needs to be lifted, and it is more convenient for the staff to find the position. The cross beam and balance plate increase the contact area between the hoisting locomotive and the ground, and increase the stability of the hoisting machine when it is working. The pad frame and rubber ring are set up to protect the hoisting locomotive. This design is not only easy to operate, but also has a high safety factor. And also improve work efficiency.

Description

technical field [0001] The invention relates to the technical field of lifting devices for highway bridges, in particular to a lifting device for highway bridges. Background technique [0002] Highway lines pass through rivers, harbors, lakes, reservoirs, irrigation canals and other waters, or across deep valleys with large height differences, or across other traffic lines. In order to keep the traffic flowing, bridges need to be erected. In bustling urban areas, sometimes viaducts are required. The elevated roads and side mountain routes are sometimes built viaducts instead of roadbeds because of the huge excavation of the roadbed, or because of the unstable geological structure, or because of the protection of the landscape. Bridges crossing rivers are generally set up to safely vent the expected maximum flood. High-water level bridges, in rivers and streams with seasonal water flow, such as small traffic volume, sometimes set low-water level bridges (also known as overflo...

AI Technical Summary

Problems solved by technology

[0004] The present invention provides a lifting device for highway bridges, which can effectively solve the above-mentioned background technology that there is no beam light, which cannot ensure that the falling route of the hook is just above the object to be lifted, and it is not convenient for the staff to find the correct position. The route is inconsistent with the object, which requires repeated adjustments by the staff, which affects work efficiency. There is no beam and balance board, which cannot increase the stability of the crane when it is working. The top of the car is prone to wear and tear on the roof
