Description

Technical Field

[0001] The utility model belongs to the technical field of highway maintenance, and in particular relates to a highway crack repairing device. Background Art

[0002] Over the long term, cracks gradually develop on highway pavements due to a combination of factors, including vehicle loads, temperature fluctuations, moisture intrusion, and material aging. These cracks not only affect the smoothness and aesthetics of the road but, more importantly, provide pathways for moisture and debris to penetrate the pavement, accelerating further damage. If effective measures are not taken to repair them promptly, cracks will gradually expand, forming more serious defects such as potholes and cracks, seriously impacting highway capacity and driving safety.

[0003] Traditional crack repair methods often directly fill the crack, neglecting surface preparation and cleaning. However, crack surfaces often cling to dust, debris, and loose particles, which can reduce the bond strength between the filler and the crack wall, thus compromising the repair effectiveness. Furthermore, irregular protrusions and depressions on the crack surface can reduce the fill density of the repair material, making the repaired crack more susceptible to re-cracking.

[0004] The crack repairing machines in the prior art only have a single repairing function, such as being only used for cleaning or filling cracks, and cannot achieve a one-stop repairing operation. Utility Model Content

[0005] In response to the above problems, the purpose of the present invention is to provide a road crack repair device to solve the problem that the crack repair machinery in the prior art only has a single repair function, such as being only used for cleaning or filling cracks and cannot achieve one-stop repair operations.

[0007] The beneficial effects of the utility model are as follows: through the use of the grinding mechanism, the cleaning mechanism and the grouting mechanism, multiple functions such as cleaning, grinding and grouting are integrated into one, thereby improving the bonding strength between the filling material and the crack wall, and ensuring the uniform distribution and dense filling of the filling material, thereby extending the service life of the highway.

[0010] The beneficial effect of this improvement is that by controlling the extension and contraction of the electric push rod, the rotating frame can be driven to rotate with the connecting shaft as the support shaft, thereby raising or lowering the grinding wheel to adjust the grinding depth of the grinding wheel.

[0011] In order to stably transmit the power of the motor to the grinding wheel;

[0015] As a further improvement of the above technical solution: a safety cover is installed on the rotating frame, and the safety cover is installed on the upper side of the grinding wheel.

[0016] The beneficial effect of this improvement is that the safety cover plays a shielding role, effectively preventing debris from splashing onto the operator's body during the grinding process of the grinding wheel.

[0017] In order to stably transmit the power of the motor to the brush disc;

[0018] As a further improvement of the above technical solution: the driving pulley and the driven pulley in the belt transmission mechanism 1 are respectively installed on the connecting shaft and the rotating shaft of the bevel gear 2, and the support frame and the connecting seat 1 are installed on the bottom of the vehicle body.
