Description

Technical Field

[0001] This utility model relates to the field of road surface crack sealing devices, and in particular to a road surface crack sealing device with a detachable walking mechanism. Background Technology

[0002] A road surface crack sealing device with a detachable walking mechanism is designed to improve the efficiency and safety of crack sealing operations while ensuring ease of operation. This device, when used in conjunction with other components, makes it easier to fill cracks in the road surface with adhesive. This design not only improves work efficiency but also facilitates disassembly and storage, reducing operating costs.

[0003] In the existing technology, a road surface crack sealing device with a detachable walking mechanism encounters cracks of different sizes when sealing the road surface. Due to the single specification of the trowel plate, the device cannot evenly spread the asphalt when encountering larger cracks, and the asphalt cannot adhere to the cracks, resulting in an uneven surface. This not only affects the aesthetics but also easily leads to waste. Therefore, it is necessary to improve the road surface crack sealing device with a detachable walking mechanism to solve the above problems. Utility Model Content

[0004] To overcome the problem that the device cannot evenly spread asphalt when encountering large gaps due to the single specification of the trowel plate, resulting in the asphalt not adhering to the gaps and thus causing the ground to be uneven.

[0009] Preferably, the fixing block has a groove at the corresponding position of the L-shaped limiting block, and the L-shaped limiting block slides in the groove. The fixing plate is restricted by the L-shaped limiting block, so that it can be smoothed more efficiently.

[0010] Preferably, the fixed plate has a groove at the corresponding position of the movable plate, and the movable plate moves in the groove. Through the groove, the fixed block can adjust the extension distance according to the corresponding needs, thereby improving the practicality of the device.

[0011] Preferably, the loading and unloading assembly includes a base frame mounted on top of a base plate. A sliding shaft is rotatably connected inside the base frame and base plate.
