Description

Technical Field

[0001] The utility model relates to the technical field of asphalt pavement construction machinery and equipment, in particular to an asphalt pavement in-situ heat regeneration unit. Background Art

[0002] Currently, in the existing technology, Chinese patent publication number CN206289505U discloses an in-situ hot regeneration unit for asphalt pavement. This unit uses a heating machine and a rake mechanism to promptly rake the heated pavement surface to facilitate subsequent milling of the asphalt pavement by a milling machine. However, in actual use, this unit faces various obstacles during construction, such as raised rocks and manhole covers. If the rake mechanism does not have an emergency obstacle avoidance function, it may not be able to avoid obstacles in time, resulting in damage to the equipment or the road surface. The rake mechanism cannot flexibly adjust to the actual conditions of the road surface, which may limit the construction speed and affect the overall construction progress. In view of this, we propose an in-situ hot regeneration unit for asphalt pavement. Utility Model Content

[0009] Preferably, the segmented movable assembly includes a connecting shaft, and the movable shaft is fixedly connected to the connecting shaft. When the rotation of the movable shaft drives the lifting movement of the connecting shaft, the segmented movable assembly needs to perform harrowing treatment of different depths on different areas.

[0010] Preferably, a sliding groove is provided on the surface of the connecting shaft, a sliding block is slidably connected in the sliding groove, and the position of the sliding block in the sliding groove is rotated to achieve different clamping and sliding relationships.

[0011] Preferably, the sliding block is elastically connected to the segmented rod via a second spring, and a slot is provided on the outer wall of the segmented rod. The sliding block is rotated so that when the sliding block slides in the sliding slot, the segmented rod is squeezed inward.

[0027] See also Figures 1-6The utility model proposes an in-situ hot regeneration unit for asphalt pavement, comprising a vehicle body 1, a combustion chamber 2 fixedly connected to the surface of the vehicle body 1, a delivery pipe 3 of the vehicle body 1 fixedly connected to a fan 4, and the above-mentioned combustion chamber 2, delivery pipe 3 and fan 4 are similar to the principles mentioned in the Chinese patent (in-situ hot regeneration unit for asphalt pavement) with authorization announcement number CN206289505U, and the effects achieved are the same. They are existing public technical means in this field and will not be elaborated here. An obstacle avoidance device 5 is provided on the outer wall of the vehicle body 1, and a segmented movable component 6 is provided on the obstacle avoidance device 5. A harrowing mechanism 7 is fixedly connected to the segmented movable component 6, and the obstacle avoidance device 5 includes a protective shell 51.

A fixing ring 53 is fixedly connected to the outer wall of the telescopic component 52, and an extrusion plate 54 is fixedly connected to the end of the telescopic component 52 away from the protective shell 51. When the vehicle body 1 contacts an obstacle, the extrusion plate 54 first contacts the obstacle and is squeezed inward by force, driving the telescopic component 52 to contract. The telescopic component 52 includes a fixing rod 521, which is fixedly connected to the inner cavity of the protective shell 51. The fixing rod 53 is fixedly connected to the outer wall of the telescopic component 52. 21 is elastically connected to the telescopic rod 523 through a spring 1 522. A fixed ring 53 is fixedly connected to the outer wall of the telescopic rod 523. The movement of the fixed ring 53 is driven by the movement and contraction of the telescopic rod 523. The inner wall of the extrusion plate 54 is fixedly connected to a scraping plate 55. The scraping plate 55 can directly act on the asphalt on the rake mechanism 7. Through its specific design and material, it can effectively scrape and remove the asphalt material adhering to the mechanism, reducing the cleaning time. A hinged rod 56 is hinged on the fixed ring 53, and the hinged rod 56 is hinged on the movable shaft 58.

When the rotating activity of the movable shaft 58 drives the lifting activity of the connecting shaft 61, the segmented movable component 6 needs to perform different depths of harrowing treatment on different areas. A sliding groove 62 is opened on the surface of the connecting shaft 61, and a sliding block 65 is slidably connected in the sliding groove 62. The sliding block 65 is rotated to The position in the sliding groove 62 realizes different snap-in and sliding relationships. The sliding block 65 is elastically connected to the segmented rod 63 through the spring 2 64, and a snap-in groove 66 is provided on the outer wall of the segmented rod 63.

The movement and contraction of the telescopic rod 523 of the telescopic assembly 52 drives the movement of the fixed ring 53. The fixed ring 53 drives the lifting of the movable shaft 58 through the hinge rod 56. The movable shaft 58 drives the lifting of the harrowing mechanism 7 through the segmented movable assembly 6 to avoid obstacles, thereby avoiding damage to equipment and road surface, reducing the safety risks of construction workers, and requiring segmented adjustment. The segmented movable component 6 rotates the position of the sliding block 65 in the sliding groove 62 to release the clamping connection, so that when the sliding block 65 slides in the sliding groove 62, the segmented rod 63 is squeezed inward. When the segmented rod 63 is squeezed, the clamping groove 66 of the segmented rod 63 and the clamping block 67 are on the same horizontal line, realizing precise rotation adjustment activity. After adjustment, the segmented rod 63 is pulled out, and the sliding block 65 slides back to the folded clamping part of the sliding groove 62, which is convenient for adapting to the construction needs of different areas and improving the use effect of the subsequent asphalt pavement in-situ hot regeneration unit.
