Description

Technical Field

[0001] The utility model relates to the technical field of highway construction, and more specifically to grouting equipment for repairing cracks on asphalt pavement. Background Art

[0002] After a long period of time, cracks will appear on the road surface after being repeatedly crushed by vehicles. These cracks not only affect the appearance of the asphalt pavement, but more seriously, they will weaken the structural integrity of the pavement, reduce the pavement's performance, and shorten its service life. The presence of cracks will cause moisture, debris and oxygen to penetrate into the pavement structure, accelerating the aging, fatigue and damage process of the pavement. Therefore, cracks are one of the common quality problems of asphalt pavements, and place higher demands on road maintenance.

[0003] In the process of road maintenance, crack filling machines are key equipment commonly used to repair road cracks. They fill and seal the cracks by injecting asphalt mixture into the cracks to prevent moisture and debris from further invading the road structure and slow down road aging and damage. However, most of the existing crack filling machines lack the function of pre-processing the cracks, such as not cleaning the dust and gravel in the cracks, which may reduce the effect of crack repair.

[0004] In addition, in actual operation, cleaning cracks is a challenge. Cracks often have irregular concave and convex shapes and tortuous structures, which makes it difficult for the cleaning tools installed on the caulking machine to remove dirt in the cracks according to the road conditions. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, a grouting device for repairing cracks in an asphalt pavement is provided to solve the problems raised in the above-mentioned background technology.

Pushing the device can make the brush wire move forward to sweep out the debris in the cracks, and a shock absorber is fixedly arranged in the connecting pipe. Through this arrangement, the brush wire can rebound and can move forward smoothly in the uneven ground cracks, so as to better adapt to the changes in the ground. The shape of the ground cracks is relatively tortuous, not straight, so a turntable is rotatably arranged on the discharge port, and a moving block is fixedly arranged on the turntable. The moving block is restricted by the second limit block and can only rotate slightly. Through this arrangement, the brush wire can also move along the ground cracks on a tortuous road surface to clean up the debris in the ground cracks. The design of this road crack repairing device takes into account the shock absorption and tortuous road conditions when cleaning the garbage in the ground cracks, so as to better clean the debris in the ground cracks and improve the quality of asphalt ground crack repair.

[0015] Through the above technical solution, the servo motor is turned on to drive the stirring rod to rotate. This setting can prevent the asphalt from sinking to the bottom and agglomerating.

[0016] Furthermore, a bottom plate is fixedly provided at the bottom of the mixing box, and two handles are fixedly provided at the top of the bottom plate;

[0017] Through the above technical solution, a bottom plate is provided to facilitate placement of the mixing box, and a handle is provided to push the device.

[0018] Furthermore, support columns are fixedly provided at the four corners of the bottom of the base plate, and universal wheels are fixedly provided at the bottoms of the four support columns;

[0019] Through the above technical solution, arranging universal wheels on the support column can facilitate the movement of the device.

[0020] Furthermore, a blower is fixedly provided on the top of the bottom plate, and an air supply pipe is fixedly provided at the air outlet of the blower;

[0021] Through the above technical solution, turning on the blower can allow the air to be transported through the air supply pipe and blown out through the air outlet pipe.

[0022] Furthermore, an air outlet pipe is fixedly provided at the bottom of the air supply pipe, a connecting rod is fixedly provided on the air outlet pipe, and the connecting rod is fixedly connected to the connecting pipe;

[0023] Through the above technical solution, the connecting pipe and the air outlet pipe can be fixedly connected through the connecting rod, so that the air outlet pipe and the brush wire can move at the same angle.

[0024] Technical effects and advantages of the utility model:

[0025] 1. The utility model proposes a grouting device for repairing cracks in asphalt pavement. When the cracks need to be repaired, the device can be pushed to the pavement to be repaired so that the brush wire can penetrate into the cracks. By pushing the device, the brush wire can move forward to sweep out the debris in the cracks, and a shock absorber is fixedly arranged in the connecting pipe. Through this arrangement, the brush wire can rebound and can move forward smoothly in the uneven ground cracks, so as to better adapt to the changes in the ground. The shape of the ground cracks is relatively tortuous, not straight, so a turntable is rotatably arranged on the discharge port, and a moving block is fixedly arranged on the turntable. The moving block can only rotate slightly due to the limitation of the second limit block. Through this arrangement, the brush wire can also move along the ground cracks on a tortuous road surface to clean up the debris in the ground cracks. The design of this pavement crack repairing device takes into account the shock absorption and tortuous road conditions when cleaning the garbage in the ground cracks, so as to better clean up the debris in the ground cracks and improve the quality of asphalt ground crack repair.
