Description

Technical Field

[0001] This utility model belongs to the field of road repair, specifically, it relates to a roadbed subsidence repair device. Background Technology

[0002] Over long-term use, roadbed subsidence often occurs, which affects vehicle driving. Repair devices are often used to repair the subsided areas.

[0003] Patent application CN210856823U discloses a roadbed subsidence repair device. Paragraph 0028 of the specification describes that, in use, the raw materials are first fed into the raw material processing tank. Then, a stirring motor drives the stirring shaft to fully process the raw materials. After processing, a solenoid valve is controlled, and the raw materials are then transported to the subsided roadbed through a conveying pipe and a metal feeding hose. A hydraulic cylinder is then used to drive the push arm, causing the buffer frame and the linkage arm to shift. A stamping pad is used to press the raw materials to maintain a horizontal position. After processing, the lifting outriggers are controlled, and the entire device is moved using moving rollers to complete the repair work in an integrated manner, resulting in high efficiency.

[0004] However, in practical applications, it is necessary to use a pressure pad to press the material at the repair site to keep it horizontal. Since there is no cleaning structure at the bottom of the pressure pad, it is easy for repair material to adhere to the bottom of the pressure pad. If the repair material attached to the bottom of the pressure pad is not cleaned in time, it will affect the level of the pressure pad pressing the material at the repair site.

[0005] To address these shortcomings, a roadbed subsidence repair device is proposed. Utility Model Content

Detailed Implementation

[0029] The present invention will now be described in further detail with reference to the accompanying drawings.

[0030] Please see Figure 1-4 As shown, this embodiment provides a roadbed subsidence repair device, including a base plate 100, a pressure pad 106 slidably fitted on the bottom of the base plate 100, and a groove 108 formed on the bottom of the pressure pad 106.

[0031] A first annular plate 200 is fixedly fitted around the pressure pad 106. A second annular plate 202 is rotatably fitted on the outer wall of the first annular plate 200. Two fixed posts 203 are fixedly fitted on the outer wall of the second annular plate 202. A sliding rod 205 is elastically and slidably fitted inside the fixed post 203. A sliding plate 208 is fixedly fitted at the lower end of the sliding rod 205. A scraper 209 is fixedly fitted between the two sliding plates 208. The scraper 209 is located inside the groove 108.

[0032] Working principle:

[0033] First, slide the pressure plate 106 downwards. The scraper 209 slides into the interior of the pressure plate 106 through the groove 108 and compacts the roadbed subsidence repair area through the plane formed by the bottom of the pressure plate 106 and the scraper 209.

[0034] After the roadbed subsidence repair area is compacted, the pressure plate 106 is slid upwards until the bottom of the pressure plate 106 is on the same horizontal plane as the upper side of the scraper 209. Then, the fixing column 203 is rotated, which drives the second annular plate 202 to rotate on the outer wall of the first annular plate 200. The fixing column 203 drives the sliding plate 208 to rotate through the sliding rod 205. The sliding plate 208 drives the scraper 209 to clean the material attached to the bottom of the pressure plate 106, reducing the problem of repair material attached to the bottom of the pressure plate 106.

[0035] The sliding plate 208 is set so that the scraper 209 rotates at the bottom of the pressure plate 106 under the action of the sliding plate 208, and the scraper 209 cleans the material attached to the bottom of the pressure plate 106 through one side, reducing the problem of repair material attached to the bottom of the pressure plate 106 and improving the level of pressure of the bottom of the pressure plate 106 on the material of the repair area.

[0036] To make the rotation of the second annular plate 202 on one side of the first annular plate 200 in this embodiment more stable, improvements are made through the following structure, such as... Figure 1-4As shown, in this embodiment, an electric push rod 105 is fixedly fitted to the bottom of the substrate 100, and one side of the pressure pad 106 is fixedly fitted to the output end of the electric push rod 105. Two Z-shaped rods 107 are fixedly fitted between the bottom of the substrate 100 and one side of the first annular plate 200. A guide hole 204 is provided on one side of the fixing post 203, and a sliding rod 205 is slidably fitted inside the guide hole 204. A fixing plate 206 is fixedly fitted to the upper end of the sliding rod 205, and a spring 20 is fixedly fitted between the bottom of the fixing plate 206 and the upper end of the fixing post 203. 7. Spring 207 is sleeved on the periphery of sliding rod 205. Multiple brushes are fixedly fitted on one side of scraper 209. One end of the brushes is fitted with one side of pressure pad 106. An annular groove 201 is opened on the outer wall of the first annular plate 200. The second annular plate 202 is rotatably fitted inside the annular groove 201. L-shaped plates 101 are fixedly fitted on both sides of substrate 100. Two rollers 102 are fixedly fitted at the bottom of L-shaped plates 101. Processing tank 103 is fixedly fitted on the upper side of substrate 100. Multiple hydraulic cylinders 104 are fixedly fitted at the bottom of substrate 100.

[0037] In this embodiment, when in use, the fixed column 203 is rotated, which drives the second annular plate 202 to rotate inside the annular groove 201. The fixed column 203 drives the sliding plate 208 to rotate through the sliding rod 205. The sliding plate 208 drives the scraper 209 to rotate. The scraper 209 drives the brush to clean the raw material attached to one side of the pressure pad 106, reducing the problem of raw material attached to the bottom of the pressure pad 106.

[0038] The annular groove 201 is provided so that the second annular plate 202 can rotate inside the annular groove 201 under the action of the fixed column 203, and the rotation direction of the second annular plate 202 is guided by the annular groove 201, which reduces the problem of the second annular plate 202 tilting during rotation and improves the stability of the second annular plate 202 during rotation.
