A road bridge maintenance repair device

Abstract

The invention provides a highway bridge maintenance and repair device, which relates to the technical field of highway bridges, to solve the problem that in the repair process of roadbed damage, workers usually need to hold a grinder to grind and repair the road surface. and splashed particles, it is easy to cause damage to the workers, and the long-term hand-held grinder will cause great damage to the arm, including the frame body; the upper end of the frame body is fixed and covered with a horizontal bearing platform; A rear sealing plate is installed on the rear end side wall of the vehicle frame body. In the present invention, since the middle part of the lower end of the toggle mechanism slides and engages with the guide rail on the bearing platform, the middle part of the rear end of the top plane of the toggle mechanism is fixed vertically upward with a driving rod, and the driving rod slides through the pressing rod mechanism, and A control switch is embedded in the upper end of the driving lever, and its control switch is electrically connected with the grinding mechanism, and the grinding mechanism can be controlled to move left and right by moving the driving lever, so as to facilitate grinding.

Description

technical field [0001] The invention relates to the technical field of highway bridges, and more specifically relates to a maintenance and repair device for highway bridges. Background technique [0002] Highway and bridge engineering includes the bridge main body (namely the bridge superstructure and bridge substructure) engineering and the auxiliary engineering facilities in the overall bridge position. There are many affiliated engineering facilities, such as revetment, diversion embankment and other structures to regulate water flow in order to maintain the stability of the bridge at the river channel, approach bridges connecting the bridge head with the road, railings on the bridge surface to prevent wheel collisions, and sidewalks to ensure the safety of pedestrians Railings, signs on the bridge, navigation signs under the bridge, and bridge deck lighting equipment, etc., while the roadbed of highway bridges is prone to damage and potholes during long-term use, and man...
