Road and bridge expansion joint repairing device

Abstract

The invention provides a road and bridge expansion joint repairing device, relates to the field of road repairing, and aims to solve the problems that an existing expansion joint repairing device cannot be automatically stressed to move and cannot be automatically inserted into an expansion joint during use. The device comprises a main body. The main body is of a rectangular structure and is made of a steel alloy material, and two vibration motors are mounted at the top end of the main body. When the main body needs to be used, after the treading pieces are pressed by manpower or a tool and the vibration motor is started, the limiting plates are pulled to move outwards, so that the limiting plates can be pulled away from the limiting pieces, the compressed springs can stretch, the rectangular plates on the two sides of the main body are pushed to move downwards, and the main body can also be stressed to move downwards; the main body can bear downward pressure while being vibrated, then the bottom of the main body can be conveniently inserted into the expansion joint, then fragments are cleared away, then asphalt or cement is added again, and the expansion joint can be restored.

Description

technical field [0001] The invention belongs to the technical field of road repair, and more specifically relates to a road and bridge expansion joint repair device. Background technique [0002] Construction expansion joints are expansion joints, which refer to a structural joint set at an appropriate part along the construction joint direction of a building or structure in order to prevent cracks or damage to the structure due to climate temperature changes (thermal expansion, cold contraction). The expansion joint is to divide the building components above the foundation such as walls, floors, and roofs (except wooden roofs) into two independent parts, so that buildings or structures can be stretched horizontally along the long direction. In higher areas, the position of expansion joints is prone to uplift and fracture. At this time, an expansion joint repair device is needed to clean and repair the expansion joints. [0003] For example, the application number: CN202010...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the above technical problems, the present invention provides a road and bridge expansion joint repair device to solve the problem that when the existing expansion joint repair device is in use, it cannot be automatically moved under force, and the repair device cannot be automatically inserted into the expansion joint. Inside, it is impossible to conveniently control the recovery of the expansion joint and clean up its internal debris, and when the existing expansion joint repair device is in use, there is no auxiliary vibration structure, and the vibration effect cannot be automatically enhanced, and the repair device cannot be quickly inserted into the expansion joint , the problem that it is impossible to quickly cut the fragments at the top of the expansion joint
