Description

Technical Field

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

[0002] When building roads, asphalt is mostly used. Asphalt is waterproof and moisture-proof, and has a large friction on vehicle tires to prevent vehicles from slipping. However, this material is prone to cracks after long-term use, which not only affects the appearance of the road, but also poses a certain risk to vehicles during driving. Therefore, highway maintenance personnel are required to regularly inspect the road surface and repair any cracks that have been found in a timely manner.

[0003] During the application process, the existing crack repair tools for road maintenance mostly adopt the method of simply filling asphalt liquid into the cracks, relying on the solidified asphalt liquid to reinforce the cracked parts. The anti-cracking effect is poor, and it is very easy for the cracks to be further expanded by external forces, affecting the safety of vehicle driving. Utility Model Content

[0004] The present invention relates to a crack repairing device for road maintenance, which solves the problem that the existing crack repairing tools for road maintenance mostly adopt the method of simply filling asphalt liquid into the cracks during use, and rely on the solidified asphalt liquid to reinforce the cracked parts, which has poor anti-cracking effect and can easily cause the cracks to be further expanded by external forces, thereby affecting the driving safety of vehicles.

[0005] In a first aspect of the present disclosure, there is provided a crack repairing device for road maintenance, specifically comprising: a repairing body; a support frame is provided at the front end of the repairing body, and a roller is rotatably connected inside the front end of the support frame; a push handle is installed at the rear of the repairing body, and a material storage funnel is welded on the top of the repairing body, and the material storage funnel is connected to the push handle; a material baffle plate is connected to the bottom of the material storage funnel; an axle pin is connected inside the repairing body, and a ring and a cotter pin are connected to the end of the axle pin; a winding wheel is installed inside the repairing body, and the axle pin runs through the winding wheel.

[0006] Furthermore, through holes are provided on both sides of the repair body, and an axle pin passes through the through holes, and the axle pin is rotatably connected to the winding wheel.

[0007] Furthermore, a high-strength mesh belt is wrapped inside the winding wheel, and the bottom rear end of the repair body is in contact with the top side of the high-strength mesh belt. Asphalt is applied to both sides of the high-strength mesh belt. When the hand push handle drives the repair body to move along the crack, the asphalt liquid inside the repair body enters the crack, and the high-strength mesh belt is laid along the crack. The high-strength mesh belt is pressed into the asphalt liquid using the rear end of the bottom of the repair body.

[0008] Furthermore, the axle pin passes through the ring, the ring is in contact with the outer side of the repair body, a connecting hole is provided at the end of the axle pin, a cotter pin is connected to the connecting hole, the cotter pin is in contact with the ring, the axle pin is fixed by the cotter pin, and the axle pin fixes the winding wheel. When the high-strength mesh belt inside the winding wheel is used up, it is convenient to replace the winding wheel.

[0009] Furthermore, the bottom of the repair body is semi-circularly provided with a bottom notch, and inclined smearing plates are provided on the left and right sides of the bottom of the repair body. Part of the asphalt liquid in the repair body flows out through the bottom notch, and the inclined smearing plates are used to smooth the outflowing asphalt liquid.

[0010] Furthermore, a leakage hole is provided at the bottom of the storage funnel, and the bottom of the storage funnel is connected to the repair body through the leakage hole. A sliding hole is provided outside the storage funnel, and a material baffle plate is slidably inserted into the sliding hole, and the top side of the material baffle plate contacts the bottom of the leakage hole.

[0011] Furthermore, a limit block is provided on the outside of the storage funnel, and a guide groove is provided on the bottom side of the baffle plate. The limit block is slidably connected in the guide groove. When the end of the crack is almost reached, the baffle plate is moved inward to seal the leak hole through the baffle plate, and the asphalt liquid inside the storage funnel stops entering the repair body.

[0012] The utility model provides a crack repair device for road maintenance, which has the following beneficial effects:

[0013] When the utility model is in use, the asphalt liquid flows into the repair body, so that the asphalt is smeared on both sides of the high-strength mesh belt. When the hand push handle drives the repair body to move along the crack, the asphalt liquid inside the repair body enters the crack, and the high-strength mesh belt is laid along the crack. The high-strength mesh belt is pressed into the asphalt liquid by using the rear end of the bottom of the repair body, and the anti-cracking effect of the cracked part after the repair is improved by the high-strength mesh belt; part of the asphalt liquid in the repair body flows out through the bottom notch, and the inclined smearing plate is used to smooth the outflowing asphalt liquid, which has the effect of smearing the asphalt liquid on the edge parts on both sides of the crack, thereby ensuring the waterproof effect of the cracked part after the repair.

[0014] In addition, the limiting block and the guide groove are slidably cooperated to prevent the baffle plate from separating from the storage funnel. When the end of the crack is about to be reached, the baffle plate is moved inward to seal the leak hole. The asphalt liquid inside the storage funnel stops entering the repair body. When the repair body reaches the end of the crack, the internal asphalt liquid can be completely used up, which facilitates the transfer of the device and reduces the waste of asphalt liquid.

[0015] Other advantages, objectives and features of the present invention will be reflected in part through the following description, and in part will be understood by those skilled in the art through research and practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS
