Description

Technical Field

[0001] This utility model belongs to the field of traffic road construction technology, specifically relating to a road surface crack repair device for traffic engineering. Background Technology

[0002] In the field of traffic engineering, road surfaces, as the direct load-bearing structure for vehicles, directly affect road traffic safety and efficiency. However, due to various factors such as natural environment (e.g., temperature changes, rain erosion, ultraviolet radiation), repeated vehicle loads, and construction techniques, road surfaces are highly susceptible to cracking and other defects during use. If these cracks are not repaired in time, they will further develop and expand, leading to a decrease in road surface structural strength, a deterioration in smoothness, and even more serious defects such as potholes and loosening, significantly shortening the road surface's service life and increasing subsequent maintenance costs.

[0003] A crucial prerequisite for road crack repair is crack cleaning. Currently, traditional crack cleaning relies on manual sweeping or simple scraping tools, which is insufficient to thoroughly remove debris (such as dust, loose particles, and old grout) from the cracks. For cracks that are narrow or deep, manual cleaning cannot reach the bottom, resulting in poor adhesion between the repair material and the crack wall, making it prone to detachment or secondary cracking. Utility Model Content

[0004] This utility model provides a road surface crack repair device for traffic engineering. It adopts a dual-mode collaborative cleaning method: a high-pressure air gun quickly removes loose particles, a high-pressure water gun deeply cleans sticky dirt, and the cracks are quickly dried through the combined action of airflow and water mist, ensuring perfect adhesion between the repair material and the crack wall. It can also achieve cleaning methods in combination with a high-pressure water gun and a pneumatic impact drill, or in combination with a pneumatic breaker. Even for cracks with small width or deep depth, it can ensure that the cracks are cleaned thoroughly and that the repair material is firmly bonded to the crack wall, making it less likely to fall off or crack again.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A road surface crack repair device for traffic engineering includes a mobile trolley with a push handle at the rear. From rear to front, the trolley comprises a power unit, a storage box, a mixing box, and a cleaning mechanism. The cleaning mechanism includes a water tank and a pneumatic box. The pneumatic box contains a high-pressure air pump. A fixed platform is located at the front of the trolley. The water pipes from the water tank and the high-pressure air pipes from the pneumatic box are fixed to the fixed platform. A concrete output pipe is located on the side of the mixing box, and a screw pump is located at the end of the concrete output pipe near the mixing box. The storage box contains a detachable high-pressure nozzle, a pneumatic impact drill, and a pneumatic breaker.

[0007] The mobile trolley is equipped with four wheels at the bottom. The two front wheels are directional wheels, each with a hub motor, and the two rear wheels are omnidirectional guide wheels.

[0008] The power source inside the power box is either a battery or an internal combustion generator.

[0009] A controller is located at the rear of the power box. The controller is connected to the mixing tank, water tank, pneumatic box and hub motor via control lines.

[0010] The storage box is divided into an equipment chamber and a material chamber, with the material chamber containing cement, asphalt, and sand.

[0011] The omnidirectional guide wheels are equipped with brakes.

[0012] By adopting the above technical solution, the beneficial effects of this utility model are:

[0013] This utility model provides a road surface crack repair device for traffic engineering. Workers control a hub motor via a controller to drive a mobile trolley forward or backward at a slow speed. Workers only need to operate a push handle to control the movement of the trolley. A cleaning mechanism is employed. When the road surface crack is deep and the surrounding area is dirty, workers first connect a high-pressure nozzle to the high-pressure air hose of the pneumatic unit. High-pressure airflow cleans the road surface crack and surrounding debris. After the debris is cleaned, the high-pressure nozzle is connected to the water hose of the water tank. High-pressure water flow is used to rinse deeper road surface cracks. Simultaneously, a pneumatic impact drill is connected to the high-pressure air hose of the pneumatic unit. The high-pressure water flow and the pneumatic impact drill work together to clean deeper road surface cracks. The high-pressure water gun can be used in conjunction with either the pneumatic impact drill or the pneumatic breaker, ensuring that the road surface cracks are thoroughly cleaned.

[0014] This invention integrates a concrete mixing tank with a combined cleaning device, employing a dual-mode collaborative cleaning approach. A high-pressure air gun quickly removes loose particles, while a high-pressure water gun deeply cleans sticky contaminants. The combined action of airflow and water mist ensures rapid drying of cracks, guaranteeing perfect adhesion between the repair material and the crack wall. It can also be used in conjunction with a high-pressure water gun and a pneumatic impact drill, or with a pneumatic breaker. Even for cracks that are narrow or deep, this invention ensures thorough cleaning and a strong bond between the repair material and the crack wall, preventing detachment or secondary cracking.
