Description

Technical Field

[0001] This utility model relates to the field of road paving technology, specifically to a crack-resistant tape laying device. Background Technology

[0002] Crack-resistant tape is a strip-shaped composite material widely used in road engineering to prevent and control reflective cracking. Its core function is to isolate and reinforce the surface, preventing cracks in the lower layer from reflecting upwards to the newly paved surface, thereby extending the service life of the pavement. The adhesive layer of the crack-resistant tape usually has a release film, which is a protective film (such as PE film or kraft paper) covering the adhesive layer. This release film is removed before construction, allowing the crack-resistant tape to adhere firmly to the road base layer.

[0003] When laying crack-resistant tape, there are problems as mentioned in the authorized publication number CN222474703U "A New Type of Convenient Construction Crack-Resistant Tape", namely, the release film on the crack-resistant tape needs to be manually removed in order for the crack-resistant tape to adhere to the road, which affects the adhesion efficiency of the crack-resistant tape. The device uses an electrical device to remove the release film on the crack-resistant tape, and the use of a motor device wastes energy; moreover, the crack-resistant tape needs to be manually compacted after it is laid. Utility Model Content

[0004] This invention addresses the problems of low efficiency in manually removing the release liner and lack of compaction components when laying anti-crack tape. An anti-crack tape laying device is provided that can remove the release liner from the anti-crack tape during the laying process, while also saving energy.

[0005] To solve the above problems, the technical solution of this utility model is:

[0006] A crack-resistant adhesive laying device includes a U-shaped plate and a winding component. Rollers are provided on the left and right ends of the two upright plates of the U-shaped plate. A U-shaped groove is provided in the center of the top surface of each of the two upright plates. Two guide rods are rotatably mounted inside the left part of the U-shaped plate, arranged from top to bottom. The winding component includes a rotating drum and a rotating rod. The two ends of the rotating drum movably pass through the right parts of the two upright plates of the U-shaped plate, and the front and rear parts of the rotating drum are rotatably connected to the two upright plates of the U-shaped plate. A rotating rod is inserted inside the rotating drum and rotatably connected to it, with both ends extending out of the rotating drum. A limiting bolt is threaded onto the rotating drum on the front side of the U-shaped plate. The free end of the limiting bolt is pressed against or away from the rotating rod. A connecting rod is coaxially connected to the roller on the right side of the front side of the U-shaped plate, and the connecting rod and the front end of the rotating rod are connected via a belt. A compaction component is provided on the U-shaped plate.

[0007] The beneficial effects of this utility model through the above technical solution are as follows:

[0008] When in use, the anti-crack tape can be gradually released and pressed onto the road by the pressure roller on the compaction component, improving the adhesion efficiency between the anti-crack tape and the road. Moreover, the release film on the anti-crack tape can automatically separate from the anti-crack tape and be wound and collected on the rotating drum on the winding component. Furthermore, the rotation of the rotating drum in this invention is achieved by the rotation of rollers, which does not require electricity and saves energy.

[0009] The separator membrane collected outside the rotating drum in this invention can be easily removed, making it convenient to use. Attached Figure Description

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0017] like Figures 1-5As shown, an anti-crack bonding device includes a U-shaped plate 1 and a winding component. The left, right, and top ends of the U-shaped plate 1 are open. Rollers 2 are provided on the left and right ends of the two upright plates of the U-shaped plate 1. A U-shaped groove 3 is provided in the middle of the top surface of the two upright plates of the U-shaped plate 1. Two guide rods 4 are rotatably provided in the left part of the U-shaped plate 1, arranged from top to bottom. The guide rods 4 are round rods. The winding component includes a rotating cylinder 5 and a rotating rod 6. The rotating cylinder 5 is a cylindrical cylinder open at both ends, with each end of the rotating cylinder 5 movably penetrating through the two upright plates of the U-shaped plate 1. On the right side of the upright plate, the front and rear parts of the rotating cylinder 5 are rotatably connected to the two upright plates of the U-shaped plate 1 via bearings 14. A rotating rod 6 is installed inside the rotating cylinder 5. The rotating rod 6 is a round rod with a diameter matching the inner diameter of the rotating cylinder 5. The rotating rod 6 is rotatably connected to the rotating cylinder 5, and both ends extend out of the rotating cylinder 5. A limiting bolt 7 is threadedly connected to the rotating cylinder 5 on the front side of the U-shaped plate 1. The free end of the limiting bolt 7 is pressed against or away from the rotating rod 6. A connecting rod 22 is coaxially connected to the roller 2 on the right side of the front side of the U-shaped plate 1. The connecting rod 22 and the front end of the rotating rod 6 are connected via a belt 8. A compaction component is provided on the U-shaped plate 1.

[0018] Each guide rod 4 is rotatably connected to two upright plates of the U-shaped plate 1 at both ends. There is a gap between the two guide rods 4, and both guide rods 4 are located in the lower part of the U-shaped plate 1. A handle 9 is provided at the right end of the U-shaped plate 1.

[0019] The connecting rod 22 is a round rod body. A pulley 10 is fixedly mounted on the outer sleeve of the connecting rod 22. A pulley 21 is fixedly mounted on the front end of the rotating rod 6. A belt 8 is mounted on both pulley 10 and pulley 21.

[0020] Limiting rods 12 are fixedly installed at the front and rear of the rotating rod 6, and the two ends of the rotating cylinder 5 slide in contact with the two limiting rods 12 respectively.

[0021] The compaction component includes a connecting plate 13 and a pressure roller 15. Rotating rods 16 are rotatably connected to the left side of the two upright plates of the U-shaped plate 1 on opposite sides. The two rotating rods 16 are symmetrically arranged front and back. The opposite ends of the two rotating rods 16 are connected to the connecting plate 13. The left ends of the two connecting plates 13 are located on the left side of the U-shaped plate 1. A cylindrical pressure roller 15 is rotatably connected between the left ends of the two connecting plates 13. A torsion spring 18 is sleeved on the outside of each rotating rod 16. One end of the torsion spring 18 is connected to the outer wall of the corresponding rotating rod 16, and the other end is connected to the upright plate of the U-shaped plate 1 on the same side.

[0022] When the lower end of the pressure roller 15 is flush with the lower end of the roller 2, both connecting plates 13 are in a state of left-low-right-high, and both torsion springs 18 are in a semi-torsed state; when the two torsion springs are in a natural state, the lower end of the pressure roller is lower than the lower end of the roller.

[0023] Before use, the hollow core of the rolled-up anti-crack patch 19 is inserted into the support rod 20, and the inner end of the anti-crack patch 19 is wound counterclockwise around the support rod 20. The two ends of the support rod 20 are respectively located in the two U-shaped grooves 3 on the U-shaped plate 1. The anti-crack patch 19 is supported by the U-shaped plate 1. The anti-crack patch 19 includes an anti-crack patch body 19a and a release membrane 19b. The anti-crack patch body 19a and the release membrane 19b pass through the space between the two guide rods 4 to the left, and the anti-crack patch body 19a is located on the upper side of the release membrane 19b. The top surface of the anti-crack patch body 19a is aligned with the upper guide rod. 4. The lower peripheral wall contacts the release film 19b and the anti-crack patch body 19a, which are manually separated between the two guide rods 4. After the release film 19b passes around the lower guide rod 4, it bends to the right. The end of the release film 19b is bonded to the rotating drum 5 on the winding part by the tape 21. The end of the anti-crack patch body 19a extends to the left out of the U-shaped plate 1 and is bonded to the road where construction is required by the pressure roller 15. Under the action of the torsion spring 18, the pressure roller 15 presses the anti-crack patch body 19a in a downward state. At the same time, the free end of the limiting bolt 7 on the winding part presses against the outer wall of the rotating rod 6.

[0024] In use, the device is pulled to the right using handle 9. Since the end of the anti-crack patch 19a is adhered to the road, it is limited. During the rightward movement, more of the rolled anti-crack patch 19a on the U-shaped plate 1 is released, and the pressure roller 15 on the compactor presses down on more of the anti-crack patch 19a to adhere to the road. Simultaneously, as the device moves to the right, multiple rollers 2 rotate. When the roller 2 at the front right end of the U-shaped plate 1 rotates, it drives the rotating rod 6 to rotate via belt 8. Since the free end of the limiting bolt 7 on the winding component presses against the outer wall of the rotating rod 6, the rotating drum 5 rotates with the rotating rod 6. When the rotating drum 5 rotates, it pulls the release film 19b away from the anti-crack patch 19a, and the separated release film 19b is wound onto the rotating drum 5. Therefore, during the rightward movement, more anti-crack patch 19a is adhered to the road, and the release film 19b is automatically separated and wound.

[0025] When the anti-crack tape body 19a is bonded and the release film 19b needs to be removed, loosen the limiting bolt 7. The free end of the limiting bolt 7 moves away from the rotating rod 6. At this time, the rotating cylinder 5 can rotate freely relative to the rotating rod 6. Pull the tail end of the release film 19b so that the rotating cylinder 5 can rotate to release the release film 19b, making it easy to remove the release film 19b.

[0026] The preferred embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Any equivalent or equivalent modifications or substitutions to the technical solutions of the present utility model without departing from the spirit of the present utility model or the scope of disclosure shall fall within the protection scope of the present utility model.
