Description

Technical Field

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

[0002] Expressways, also known as highways, are roads designed for high-speed driving. There are different regulations for expressways in different countries, regions, eras, and scientific research fields. According to China's "Highway Engineering Technical Standards", expressways are multi-lane roads designed for vehicles to drive in different directions and lanes, with full access control. After a long period of use, cracks may appear on the road surface of the expressway, which needs to be repaired to ensure normal use. Usually, a highway pavement crack repair and caulking machine is used.

[0003] Existing highway pavement crack repair and caulking machines generally include a mobile base plate, a storage tank fixedly connected to the upper end of the mobile base plate, and a discharge port connected to the storage tank through a hose. When working, the device needs to be pushed to the road surface to be repaired, and then the discharge port is driven to move back and forth. During the reciprocating movement, the asphalt inside the storage tank will enter the cracks along with the hose and the discharge port, thereby repairing it layer by layer.

[0004] Since the shapes of cracks on highway pavement are not fixed and may extend in a straight line or in an irregular curve, the reciprocating movement of the discharge port can only repair regular straight line cracks, which is less practical. Summary of the invention

[0005] The utility model aims to provide a highway pavement crack repairing and caulking machine, which can adapt to straight and irregular curved pavement cracks and improves practicability.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a highway pavement crack repair and caulking machine, comprising a mobile vehicle and a storage tank fixedly connected to the mobile vehicle, the right end of the mobile vehicle is fixedly connected to two horizontal plates distributed up and down, two sliding rods distributed front and back are fixedly connected between the two horizontal plates, the outer walls of the two sliding rods are slidably connected with a sliding block, the right end of the sliding block is fixedly connected to two connecting plates distributed up and down, a movable column is rotatably connected between the two connecting plates through two bearings, the right end of the movable column is fixedly connected to a connecting block, the lower end of the connecting block is fixedly connected to a discharging barrel, the lower end of the discharging barrel is equipped with a discharging nozzle, the lower end of the lower connecting plate is fixedly connected to a supporting block, and the lower end of the supporting block is fixedly connected to a universal ball.

[0007] In order to facilitate the pumping of asphalt into the discharge barrel, as a preferred highway pavement crack repair and caulking machine of the utility model, the interior of the mobile vehicle is fixedly connected with an asphalt pump whose feed end is connected to the interior of the storage tank, and the upper end of the discharge barrel is penetrated by a hose connector extending to the top of the connecting block.

[0008] In order to prevent the asphalt from solidifying quickly, as a preferred highway pavement crack repair and caulking machine of the utility model, the upper end of the inner wall of the storage tank is rotatably connected to a stirring frame through a bearing, and the stirring frame is driven by a motor installed on the upper end surface of the storage tank.

[0009] In order to facilitate the feeding of the storage tank, as a preferred highway pavement crack repair and caulking machine of the utility model, the upper end of the storage tank is penetrated and connected with a feeding port located on the left side of the motor.

[0010] In order to facilitate the control of the forward and backward swinging of the connection block, as a preferred embodiment of the highway pavement crack repair and caulking machine of the utility model, the upper end of the connection block is fixedly connected with a T-shaped operating rod located on the right side of the hose connector.

[0011] In order to facilitate the pulling of the utility model to make it move, as a preferred highway pavement crack repair and caulking machine of the utility model, the left end of the mobile vehicle is fixedly connected with a U-shaped pull rod.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] When the universal ball contacts the road surface, the lower end of the discharge nozzle will be higher than the lower end of the universal ball, thereby preventing the discharge nozzle from directly contacting the ground. Then the utility model is pulled to move, and the asphalt enters the crack through the discharge nozzle, thereby repairing the crack. When the crack is curved, the connecting block is controlled to swing back and forth with the movable column according to the direction of the crack, driving the discharge barrel and the discharge nozzle to swing back and forth, thereby adapting to straight and irregular curved road cracks, thereby improving practicality.
