Expansion joint cleaning device for bridge maintenance

Abstract

The invention provides an expansion joint cleaning device for bridge maintenance, and relates to the technical field of bridge maintenance. The expansion joint cleaning device includes a vehicle board, a cleaning box is fixedly connected to the top of the vehicle board, a first sliding rod is fixedly connected to the inner side wall of the cleaning box, two movable rods are slidably connected to the outer surface of the first sliding rod, and two connecting plates are fixedly connected to the side surface, close to each other, of the two movable rods. According to the expansion joint cleaningdevice for bridge maintenance, connecting rods drive the movable rods to reciprocate left and right on the outer surface of the first sliding rod, so that brush plates at the bottom of the movable rodreciprocate left and right to clean an expansion joint, when encountering clumps which are difficult to clean, a second motor is started to drive a cam to rotate, a shovel block reciprocates left andright through the convex end of the cam and under the action of the rebound of a spring, so that the clumps which are difficult to clean in the expansion joint are shoveled and cleaned up, thus the time-saving and labor-saving effects are achieved, and the cleaning effect is high.

Description

technical field [0001] The invention relates to the technical field of bridge maintenance, in particular to an expansion joint cleaning device for bridge maintenance. Background technique [0002] Bridge refers to a building built for roads to cross natural or artificial obstacles. It is erected on rivers, lakes and seas to enable vehicles and pedestrians to pass smoothly. Building expansion joints are expansion joints. Change (thermal expansion, cold shrinkage), a structural joint set along the appropriate part of the construction joint direction of a building or structure that causes cracks or damage to the structure, [0003] At present, when cleaning expansion joints, manual cleaning is usually used to clear the debris inside the expansion joints. The difficult-to-clean agglomerated impurities also need to be manually shoveled and cleaned with a shovel. This cleaning method is time-consuming and labor-intensive, and cleaning is difficult. Clean and greatly reduce the lo...
