Highway bridge expansion joint cleaning device

Abstract

The invention discloses a highway bridge expansion joint cleaning device. The device comprises a device body, a first cleaning mechanism, a front righting mechanism, a second cleaning mechanism and arear righting mechanism are sequentially arranged on the device body from front to back. Two push rods are arranged at the rear end of the vehicle body; the first cleaning mechanism comprises a cleaning wheel, a cutting disc, a rotating frame, a fixed cylinder, a first driving motor and a rotating motor; the lower side of the rear end of the fixed cylinder is hinged to the vehicle body, an arch frame is fixed to the front end of the vehicle body, the upper side of the bottom end of the fixed cylinder is movably connected with the arch frame through a swing air cylinder, and the top end of therotating frame is cylindrical and is arranged in the fixed cylinder in a rotatable mode. Two connectors are arranged at the bottom end of the rotating frame, and the cleaning wheel and the cutting disc are rotationally arranged on one connector. The cleaning device has the characteristics that the cleaning mode can be freely switched, righting is conducted at any time, and cleaning is thorough.

Description

technical field [0001] The invention relates to a cleaning device for expansion joints of highway bridges. Background technique [0002] During the construction of the bridge, in order to prevent the structure from cracking due to temperature changes (thermal expansion and contraction), an expansion joint is often set at an appropriate position. The expansion joints of the highway bridge need to be cleaned regularly, and there will be cracks during the cleaning process. The following problems: 1. The traditional method, manual cleaning with tools such as crowbars, is difficult to operate, time-consuming and labor-intensive. 2. The existing cleaning machinery and equipment are mainly cleaned by high-pressure water guns and seam cleaning machines. The high-pressure water gun uses high-pressure water to flush out the sundries in the expansion joints. For some sundries with high compaction or mixed with stone Block expansion joints are difficult to clean. The seam cleaning mac...

Problems solved by technology

[0002] During the construction of the bridge, in order to prevent the structure from cracking due to temperature changes (thermal expansion and contraction), an expansion joint is often set at an appropriate position. The expansion joints of the highway bridge need to be cleaned regularly, and there will be cracks during the cleaning process. The following problems: 1. The traditional method, manual cleaning with tools such as crowbars, is difficult to operate, time-consuming and labor-intensive

2. The existing cleaning machinery and equipment are mainly cleaned by high-pressure water guns and seam cleaning machines. The high-pressure water gun uses high-pressure water to flush out the sundries in the expansion joints. For some sundries with high compaction or mixed with stone Block expansion joints are difficult to clean

The seam cleaning machine cuts the sundries in the expansion joints into debris through the rotating cutting disc, and then cools and blows them through the high-pressure fan. This method of cleaning all the expansion joints does not appear to have a high utilization rate. For some compaction High debris can be cut with a cutting disc, but for some expansion joints with relatively low compaction of debris but containing stones, it is a waste of time, and the crushed stones are easy to shift during cutting, As a result, the high-pressure fan in the later stage is difficult to blow, resulting in low cleaning efficiency

3. The cleaning machinery and equipment are prone to offset during the moving process, causing the cutting disc to touch the steel plates on both sides of the expansion joint or the road surface, causing damage
