Description

Technical Field

[0001] The utility model relates to the technical field of road seam tapes, in particular to a seam tape laying and compacting device. Background Art

[0002] After long-term use of asphalt pavement, cracks will appear in the surface layer under the influence of factors such as vehicle load, temperature and humidity. If not handled in time, rainwater will easily enter the surface layer and base layer through the cracks, causing cracks, potholes and other defects on the road surface. When the above problems occur, the common treatment method is to use seam tape for repair. The laying of seam tape usually includes processes such as cleaning the road surface, pasting and compacting. Common compaction devices generally consist of a compaction roller and a push rod. The compaction roller is installed at the bottom of the push rod and is driven forward by the push rod. However, there is usually a lot of dust, gravel and asphalt for filling the gaps at the paving site. When the compaction roller is moving, dust, gravel, asphalt and other debris are easy to adhere to the surface of the compaction roller, making the surface of the compaction roller uneven, affecting the compaction effect.

[0023] See also Figure 1 and Figure 2 The utility model provides a joint tape laying and compacting device, including a compacting roller 4, a traction component and a scraper component.

[0024] The compacting roller 4 has a predetermined length, and includes a roller wall and side walls arranged on both sides of the roller wall. The two side walls of the compacting roller 4 are formed with an axially protruding connecting shaft 2. Specifically, the connecting shaft 2 and the side walls can be fixed by welding, and the compacting roller 4 can be made of metal such as steel or iron. In addition, the length of the compacting roller 4 is not less than 15 cm, and its outer diameter is not less than 10 cm. For example, the length of the compacting roller 4 is 20 cm. The outer diameter of the compacting roller 4 is 12 cm to ensure that the compacting roller 4 can be applied to most seam tapes.

[0025] The traction component includes a support frame and a push rod 3. The support frame includes a connecting arm 1 and two support plates 5. The two support plates 5 are respectively connected to the connecting shafts 2 on both sides of the compaction roller 4. The connecting arm 1 is arranged between the two support plates 5 to connect the two. The push rod 3 is fixed on the connecting arm 1 and is arranged perpendicular to the connecting arm 1. Specifically, the connecting arm 1 and the support plate 5 and the push rod 3 and the connecting arm 1 can be fixed by bolts or by welding.

[0026] The scraper component includes a first scraper 6 and a second scraper 7. The first scraper 6 and the second scraper 7 are both arranged on the compaction roller 4, and both extend along the axial direction of the compaction roller 4. The lower end surface of the first scraper 6 is 1-3 mm away from the roller wall of the compaction roller 4. For example, the lower end surface of the first scraper 6 is 2 cm away from the roller wall of the compaction roller 4, and the lower end surface of the second scraper 7 is in contact with the roller wall of the compaction roller 4, and the first scraper 6 is located below the second scraper 7.

[0027] It is understandable that, when the compacting roller 4 is moving, the first scraper 6 can first remove some of the debris on the compacting roller 4, and the second scraper 7 can then completely remove the debris on the compacting roller 4, so that the surface of the compacting roller 4 can be kept smooth, ensuring the compaction effect of the compacting device. In addition, the first scraper 6 and the second scraper 7 work simultaneously, which can improve the cleaning effect, and the first scraper 6 can reduce the cleaning pressure of the second scraper 7, thereby increasing the service life of the second scraper 7.

[0028] It should be noted that the lower end surface of the first scraper 6 is serrated, which can effectively destroy asphalt and other debris, thereby improving the cleaning effect. The lower end surface of the second scraper 7 is blade-shaped, so that the lower end surface of the second scraper 7 is sharper, thereby increasing its cleaning strength.

[0029] Specifically, both ends of the first scraper 6 and the second scraper 7 are connected with a connecting plate 8, and the first scraper 6 and the second scraper 7 are fixedly connected to the two support plates 5 of the support frame through the connecting plate 8 to ensure the stability of the first scraper 6 and the second scraper 7. In addition, the connecting plate 8 and the support plate 5 can be fixed by welding or the like.

[0030] Optionally, the roller wall and the side walls on both sides thereof enclose an internal space, and at least one of the two side walls is provided with a water injection port, and the water injection port is connected to a closure member 9. When in use, water can be injected into the compacting roller 4, so that the compacting roller 4 has a certain mass, improves the compaction effect, and can also save materials. Furthermore, the inner wall of the water injection port is provided with a thread, and the closure member 9 is a bolt member, so as to facilitate the removal and installation of the seal.

[0031] In one embodiment, the push rod 3 is a telescopic rod, and the operator can adjust the length of the push rod 3 according to the usage habits. Specifically, the push rod 3 may include two sections of rods, one of which is inserted into the other, and the two are locked by bolts or other fixings. In addition, a handle is connected to the end of the push rod 3 away from the support frame, and the push rod 3 is driven by the handle, which is convenient to use.

[0032] Optionally, a reinforcing rod 10 is provided between the push rod 3 and the connecting arm 1 , so as to improve the stability between the push rod 3 and the connecting arm 1 , thereby increasing the stability of the overall structure.

[0033] The above are only preferred implementations of the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
