A bridge expansion joint cleaning device

Abstract

The invention belongs to the technical field of bridge expansion joint cleaning, and in particular relates to a bridge expansion joint cleaning device, which includes a car body, hinged wheels on the bottom surface of the car body, a water storage tank connected to the high-pressure water gun in the car body, and an end mounted on the bottom surface of the car body. Rotate the first cylinder and the second cylinder that match the first rotating shaft and the second rotating shaft, install the first guide plate at one end of the first rotating shaft, install the second guiding plate at one end of the second rotating shaft; set the other end of the first rotating shaft and the second rotating shaft There is a transmission mechanism. The bracket is installed on the bottom of the car body, and the frame bar is installed at the end of the bracket; the hook cover is installed on the inside of the frame bar; The front end is provided with a guide wheel mechanism. When the bridge expansion joint cleaning device of the present invention is used to clean the bridge expansion joints, the water spray direction of the high-pressure water gun can be perpendicular to the bottom surface of the expansion joints, and can also be perpendicular to the side walls of the expansion joints, and the high-pressure water has a good effect on the expansion joints. Clean up effect.

Description

technical field [0001] The invention belongs to the technical field of bridge expansion joint cleaning, and in particular relates to a bridge expansion joint cleaning device. Background technique [0002] The bridge expansion joint is an expansion device installed at the movable end of the bridge superstructure and the broken joint of the bridge deck. The function of installing expansion joints is to ensure that the changes of the upper structure can be realized under the action of temperature changes, concrete shrinkage and creep, and loads without generating additional additional internal forces, and to ensure smooth driving. During actual use, a lot of debris will accumulate in the expansion joints of the bridge, which will affect the expansion performance of the expansion joints, so it is necessary to regularly clean the debris in the expansion joints. The traditional way of cleaning expansion joints is to manually clean up the sundries in the expansion joints. This met...

Problems solved by technology

[0006] The invention provides a bridge expansion joint cleaning device, the purpose of which is to solve the following problems when the expansion joint cleaning device in the prior art is used to clean the bridge expansion joints: (1) the water spraying direction of the water spray valve is perpendicular to The bottom surface of the expansion joint is parallel to the side wall of the expansion joint, and the cleaning effect on the side wall of the expansion joint is not good; (2) After receiving the impact of high-pressure water and overflowing the expansion joint, the dirt is randomly scattered on both sides of the expansion joint on the bridge deck After cleaning the expansion joints, it is still necessary to collect and clean the dirt on both sides of the expansion joints on the bridge deck, so as to prevent the dirt from returning to the expansion joints again. The operation is more cumbersome
