Description

Technical Field

[0001] This utility model relates to the technical field of crack repair devices for highway maintenance, and particularly to a crack repair device for highway maintenance. Background Technology

[0002] During the construction of highway bridges, cracks may appear on the surface of the road and bridge due to the pressure of vehicles and the effects of external temperature. Crack repair devices are needed in this case.

[0003] In existing road repair methods using hot patching, heated asphalt is typically poured into a repair tool from an asphalt heating device, and then repair personnel push the tool along the road crack to perform the repair operation. Since only a small amount of heated asphalt is usually poured into the repair tool to prevent the asphalt from hardening, frequent replenishment of heated asphalt is required, which reduces the efficiency of road repair. Therefore, a road crack repair device is proposed to address the above problems.

[0004] Existing patent (publication number: CN221072234U) discloses a road crack repair device, including a box body. A roller is rotatably connected to the bottom outer end of the box body via a rotating shaft. A discharge pipe slidably connects to the bottom end of the box body, penetrating the box body. Through the box body, pull rod, discharge rod, baffle, pull rope, and electric heating tube, when repairing road cracks via heat patching, asphalt is added to the box body and heated by the electric heating tube. Then, the pull rod pulls the pull rope, further pulling the baffle to the right via the sleeve rod and inner rod. During this process, the push rod rotates, further pushing the discharge pipe down to contact the ground via the baffle. When the discharge pipe contacts the ground, the heated asphalt flows out through the discharge pipe and further into the road crack. Therefore, at this point, only the device needs to be slowly moved along the road crack to perform the road repair operation, eliminating the need for frequent asphalt dispensing and thus improving the efficiency of road repair.

[0005] To address the aforementioned issues, existing patents offer solutions. However, most existing crack repair devices are not convenient for adjusting the material feeding structure according to road conditions, and the material feeding structure is designed at the bottom of the movable structure, making it difficult for users to observe it, which can easily increase the difficulty of construction.

[0006] Therefore, a crack repair device for highway maintenance is proposed. Utility Model Content

[0007] The purpose of this invention is to provide a crack repair device for highway maintenance, which can solve the problems of most existing crack repair devices not being able to adjust the material feeding structure according to the road surface conditions, and the material feeding structure being designed at the bottom of the moving structure, making it difficult for users to observe it, thus increasing the difficulty of construction.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a crack repair device for highway maintenance, comprising a base plate, an asphalt storage device body bolted to the top of the base plate, a discharge assembly connected to the bottom of the asphalt storage device body, and a leveling assembly provided on the rear side of the discharge assembly.

Two adjustment blocks are threadedly connected to the surface of the bidirectional threaded rod. An inclined plate is fixedly connected to the bottom of each of the two adjustment blocks.

[0010] Preferably, the leveling assembly includes a connecting plate, a spiral rod is threadedly connected to the inside of the connecting plate, a rotating block is fixedly connected to the bottom of the spiral rod, a frame is fixedly connected to the surface of the rotating block, and a rolling wheel is connected to the inner side of the frame.

[0011] Preferably, a control block is fixedly connected to the top of the screw rod, and the control block is made of stainless steel.

[0012] Preferably, a sliding groove is provided on the rear side of the housing, and a sliding block is slidably connected inside the sliding groove. The sliding block is welded to the front side of the connecting plate.

[0013] Preferably, the bottom of the base plate is fixedly connected to a caster wheel, and a push frame is bolted to the rear side of the base plate.

[0014] Preferably, the top of the base plate is fixedly connected to the box body, the top of the box body has a groove, a protective pad is fixedly connected inside the groove, and a tool box is slidably connected inside the box body.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. In this application, the coordinated work of the first servo motor body, bidirectional threaded rod and adjusting block in the discharge assembly enables precise adjustment of the discharge space according to the actual road conditions. Different road crack widths, depths and smoothnesses will affect the optimal discharge amount and distribution of asphalt. By driving the bidirectional threaded rod to rotate through the first servo motor body, the two adjusting blocks can be moved in opposite directions, thereby changing the spacing of the inclined plates.

[0019] 2. In this application, the roller in the leveling component can effectively level the asphalt after it has been applied by contacting the road surface. As highway surfaces will experience varying degrees of wear and deformation during long-term use, resulting in different degrees of flatness, the roller can rotate flexibly with the undulations of the road surface, spreading the asphalt evenly in the cracks and making it better fit the road surface.
