Description

Technical Field

[0001] The utility model relates to the technical field of concrete pavement repair, in particular to a pavement crack repair and filling device. Background Art

[0002] Concrete roads under construction will develop cracks over a long period of time. This is due to physical structural changes caused by the action of internal and external factors of the concrete structure. During the construction of concrete, due to large temperature differences, or the concrete being attacked by cold waves, the surface temperature of the concrete will drop sharply, resulting in shrinkage cracks. This type of crack usually only occurs in a shallow range on the concrete surface. After the concrete structure is formed, it is not covered in time, the surface moisture is lost quickly, and the volume shrinks greatly. Common treatment methods for concrete cracks include filling, grouting, structural reinforcement, concrete replacement, and electrochemical protection.

[0003] After long-term use of the concrete pavement during construction, some cracks will appear on the pavement. Utility Model Content

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-4 A road crack repair and filling device comprises a vehicle body 1, a traveling mechanism is installed on the vehicle body 1, the traveling mechanism comprises two symmetrically arranged mounting shafts, and each mounting shaft is installed on the side wall of the vehicle body 1, each mounting shaft is installed with a traveling frame 8, each traveling frame 8 is symmetrically installed with a plurality of traveling wheels 9, a mounting recess 10 is provided on the lower end surface of the vehicle body 1, one end of each mounting shaft away from the traveling frame 8 extends to the mounting recess 10 and is installed with a bevel gear 12, a horizontal shaft is horizontally installed in the mounting recess 10, a bevel gear 2 11 is installed on the horizontal shaft, and each bevel gear 12 is meshed with the bevel gear 2 11;

[0023] A pushing frame 3 is installed on the side wall of the vehicle body 1, a storage box 15 is installed on the inner wall of the vehicle body 1, a heater is installed on the outer surface of the storage box 15 to ensure that the asphalt inside the storage box 15 is in a liquid state to prevent it from solidifying, a feed pipe 2 is connected to the storage box 15, and the upper end of the feed pipe 2 passes through the vehicle body 1 and extends upward, a pushing assembly is installed at the lower end of the storage box 15, a pump body 5 is installed on the outer wall of the vehicle body 1, the storage box 15 and the pump body 5 are connected through a connecting pipe 6, a hose 7 is connected to the lower end of the pump body 5, the end of the hose 7 extends into the vehicle body 1 and is installed with a filler 4, and the filler 4 is located at the output end of the pushing assembly, the pushing assembly includes a telescopic rod 17, and the filler 4 is installed at the output end of the telescopic rod 17, a through hole 13 is opened on the lower end surface of the vehicle body 1, and the lower end of the filler 4 is located in the through hole 13;

[0024] A limiting cylinder 14 is installed on the lower end surface of the storage box 15, and the limiting cylinder 14 is located in the through hole 13, and the telescopic rod 17 is located in the limiting cylinder 14. A limiting groove 16 is provided on the outer wall of the limiting cylinder 14, and the hose 7 is located in the limiting groove 16. The output end of the telescopic rod 17 drives the filler 4 to move downward, shortening the distance between the discharge end of the filler and the road cracks, and improving the accuracy of the filler 4 in filling and repairing the road cracks. During the movement of the filler, the hose 7 moves in the limiting groove 16 without affecting the movement of the telescopic rod 17. During the movement of the vehicle body 1, the filler 4 is completely stored in the limiting cylinder 14 to prevent the filler 4 from extending outside the vehicle body 1 and affecting the movement of the vehicle body 1.

[0025] The operator pushes the vehicle body 1 through the push frame 3 to push the device to the desired position. When it is necessary to fill and repair the cracks on the road surface, the telescopic rod 17 is first opened, and the output end of the telescopic rod 17 drives the filler 4 to move downward, shortening the distance between the discharge end of the filler 4 and the cracks on the road surface. Then, the pump body 5 is opened, and the pump body 5 guides the asphalt inside the storage box 15 into the filler 4 and guides the asphalt into the cracks to achieve repair;

[0026] When the vehicle is traveling in a straight line, the resistances encountered by the running wheels 9 on the left and right sides are basically the same, and the bevel gear 1 12 and the bevel gear 2 11 do not rotate. The running wheels 9 rotate to realize the movement of the vehicle body 1. When the vehicle body 1 turns or encounters an uneven road surface during movement, the driving path of the inner wheel is shorter than that of the outer wheel, and the resistance is relatively small. The bevel gear 1 12 at the corresponding position rotates, and the vehicle body 1 drives the bevel gear 2 11 to remain stationary in its initial state, so that the outer wheel speeds up and the inner wheel speeds down, thereby realizing that the left and right wheels rotate at different speeds, which can not only ensure smooth turning of the vehicle, but also prevent the wheels from excessive sliding or locking, reduce tire wear, and at the same time ensure that the vehicle body 1 is always parallel to the ground, reduce the shaking of the asphalt inside the storage box 15, coordinate the speed difference of the left and right wheels of the vehicle under different driving conditions, and ensure the stability and flexibility of the vehicle driving.
