Description

Technical Field

[0001] The utility model relates to the technical field of pavement maintenance, and more specifically, to a pavement maintenance seam sealing device. Background Art

[0002] The road surface is subject to vehicle loads and erosion by natural forces such as wind, rain, ice and snow, freeze-thaw, and sunlight. It is susceptible to damage, such as cracks. Therefore, necessary maintenance and management work must be carried out. When dealing with road cracks, seam tape is generally used for repair. At this time, a seam tape laying device is needed.

[0003] After searching, a Chinese patent with publication number CN216864769U discloses a device for laying seam tape for repairing road cracks, which is convenient for cleaning dust on the road surface on both sides of the crack, thereby ensuring the laying effect of the seam tape. At the same time, the seam tape can be flattened after laying, so that bubbles are not easily generated between the seam tape and the road surface, which not only ensures the appearance but also improves the laying quality of the seam tape.

[0004] Although the above-mentioned seam tape laying device can achieve certain use effects, it still has some shortcomings in actual use:

[0005] 1. Use a vacuum pump to absorb the dust around the crack to increase the adhesion quality of the seam tape. Only the influence of dust is considered. However, in fact, there are some large particles around the crack. Some of these particles are large in mass and cannot be directly absorbed by the force of the vacuum. They will still affect the adhesion of the seam tape.

[0006] 2. When the roller pressing structure is actually used, the height of the bottom roller remains fixed after the height of the cylinder itself is adjusted. In fact, the road surface itself is not flat, and there are some raised or sunken areas in some places. During the rolling process, the height of the roller is fixed, which will affect the stability of the rolling. Utility Model Content

[0034] Working principle: This utility model designs a road maintenance and sealing device. The specific structure is as shown in the attached manual. Figure 1-6As shown, when the present technical solution is in use, the seam sealing device is first moved to the crack position of the road surface, and then the exhaust fan 8 and the motor 19 are started at the same time. The operation of the motor 19 in the cleaning mechanism drives the two gears 18 to rotate. Since the two gears 18 are meshed with each other, the rotation directions are opposite, which facilitates the two shaft rods 17 to rotate in the opposite direction, and then drives the two cleaning rods 21 at the bottom to rotate in the opposite direction. By controlling the reciprocating motion of the two cleaning rods 21, it is convenient to use the cleaning brush 22 at the bottom of the cleaning rod 21 to clean the area around the crack, thereby sweeping away the particles around the crack, avoiding affecting the stability and flatness of the subsequent seam sealing belt 6 after seam sealing, and using the second locking bolt 23 to adjust the connection position of the connecting tube 20 at the end of the shaft rod 17, so as to facilitate adjusting the working height of the cleaning rod 21.

When the exhaust fan 8 is running, the compressed air makes the area around the position of the wind hood 10 The air is absorbed and filtered by the dust filter box 7, and the dust remains in the dust filter box 7 for subsequent treatment. The angle adjustment mechanism is provided to facilitate the adjustment of the working angle of the wind hood 10 when in use, so as to carry out dust suction treatment on spaces of different ranges as needed. Then, one end of the seam sealing tape 6 is attached to the position where the crack is located. By moving the seam sealing device, the seam sealing tape 6 gradually seals the cracks in the road surface due to the tension maintained by the adhesive force of the bonding. During the movement, the seam sealing tape 6 attached to the road surface is rolled by the provided rolling mechanism 24. In the rolling mechanism 24, the lifting and lowering of the lifting plate 242 can be conveniently controlled by turning the hand wheel 247, thereby driving the lifting and lowering of the adaptive rolling assembly 245.
