Description

Technical Field

[0001] This utility model relates to the technical field of asphalt pavement repair equipment, specifically an asphalt pavement repair roller. Background Technology

[0002] Traditionally, asphalt is laid on the road surface during asphalt road repair and then rolled over using a large-mass roller. After rolling, the road surface is made flat and compacted. The compaction process mainly involves using some rolling equipment to apply some form of load to the laid asphalt concrete, overcoming the internal friction and cohesion of the asphalt concrete, causing the aggregates of different sizes to shift and move closer to each other, and reducing voids by expelling internal air, thereby causing the asphalt concrete to undergo plastic deformation and become dense.

[0003] A search revealed Chinese patent application number CN202211478479.0, which relates to a hot rolling system for asphalt pavement in road construction. This application addresses the problem of poor paving effect of existing rolling mechanisms. It includes an engineering transport vehicle, a hopper mounted on the vehicle, and a rolling mechanism located at the rear of the vehicle. It also includes a guide mechanism at the hopper's discharge port, comprising multiple guide pipes connected to the hopper's discharge port and a conveying assembly for transporting asphalt within the guide pipes. The discharge ports of the multiple guide pipes are located within the rolling area of ​​the rolling mechanism. This application achieves the effect of simultaneously transporting asphalt through multiple guide pipes, increasing the paving area after the asphalt is discharged from the hopper, and then leveling the asphalt on the ground using the rolling mechanism, resulting in faster and better paving.

[0004] However, the application still has the following shortcomings:

[0005] During asphalt road maintenance, construction workers need to cut and repair the cracks according to their size, and then pour asphalt concrete and compact it using a roller compactor. However, asphalt roads may have cracks of varying widths during repair. Using a uniformly large roller compactor can cause the following problems: 1. A large roller compactor may simultaneously compact the road around the crack, which can lead to poor compaction of the asphalt filling inside the crack; 2. A large roller compactor is inconvenient to transport, and repairing smaller road cracks is time-consuming and labor-intensive, with difficulties in transportation and transfer. Therefore, we need to propose an asphalt pavement repair roller compactor to solve the above problems. Utility Model Content

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-3 This utility model provides a technical solution: an asphalt pavement repair rolling machine, including a rolling frame assembly 100, an engineering vehicle 400 fixed at one end of the rolling frame assembly 100, and a repair rolling assembly 300 provided at the other end of the rolling frame assembly 100, the repair rolling assembly 300 being connected to the rolling frame assembly 100 via a connecting assembly 200;

[0024] The rolled frame assembly 100 includes a support frame 101, and the repair rolled assembly 300 includes a rolled cylinder 301;

[0025] The connecting assembly 200 includes two sets of fixing rings 201 and a mounting plate 211. The two sets of fixing rings 201 are respectively fixed on both sides of the rolling cylinder 301. Multiple sets of countersunk holes 202 are opened on the inner and outer side walls of the fixing rings 201. Multiple sets of threaded sleeves 212 are fixed on the side wall of the mounting plate 211. The threaded sleeves 212 are internally threaded with a first reinforcing rib threaded rod 203. The mounting plate 211 is fixed in the fixing rings 201 through the cooperation of the first reinforcing rib threaded rod 203 and the countersunk holes 202.

[0026] When installing this device before use, select a repair rolling assembly 300 suitable for the site operation, that is, select a rolling cylinder 301 of appropriate size. The two fixing rings 201 are fitted onto the outside of the two sets of mounting discs 211. Then, the first reinforcing rib threaded rod 203 is threaded onto the threaded sleeve 212, so that the mounting disc is fixed in the fixing ring 201. The rolling frame assembly 100 can then be pushed by the engineering vehicle 400, so that the rolling cylinder 301 of appropriate size can perform repair rolling operations on the asphalt pavement.

[0027] In practical use, rollers 301 of different sizes and diameters are installed on the roller frame assembly 100 through the connecting component 200. Driven by the engineering vehicle 400, the rollers 301 roll the asphalt concrete, thereby repairing the cracks in the asphalt pavement. This device can be installed with appropriate rollers according to the site environment, thus improving the practicality of the device.

[0028] One end of the first reinforcing threaded rod 203 extending out of the fixing ring 201 is integrally formed with a limiting block. The limiting block and the countersunk hole 202 work together to limit the length of the first reinforcing threaded rod 203 entering the screw sleeve 212 when the first reinforcing threaded rod 203 is threadedly connected to the screw sleeve 212. At the same time, it prevents the first reinforcing threaded rod 203 from protruding from the fixing ring 201 and falling off the fixing ring 201.

[0029] The first reinforcing threaded rod 203 is threaded with a first nut 204. The first nut 204 is located between the fixing ring 201 and the threaded sleeve 212, and the first nut 204 is also used in conjunction with the countersunk hole 202 to prevent the first reinforcing threaded rod 203 from shifting and falling off due to vibration during use after it is fixed.

[0030] A heating through hole is provided inside the rolling cylinder 301, and a heat-conducting cylinder 302 is fixed inside the heating through hole. A heating wire is provided inside the heat-conducting cylinder 302. When laying asphalt, the heating wire is energized and heated, so that the rolling cylinder 301 can maintain the temperature of the asphalt during rolling, avoiding the problem that the asphalt is difficult to flatten during rolling, resulting in poor paving effect.

[0031] A bearing 213 is embedded and fixed on the mounting plate 211. A second reinforcing rib threaded rod 214 is fixed to the inner ring of the bearing 213. The end of the second reinforcing rib threaded rod 214 away from the bearing 213 passes through the support frame 101. Two sets of limiting nuts 215 are threadedly connected to the second reinforcing rib threaded rod 214. The two sets of limiting nuts 215 are located on both sides of the lever arm of the support frame 101, so as to limit the second reinforcing rib threaded rod 214 by the two sets of limiting nuts 215, and prevent it from shifting or falling off the support frame 101 during use.

[0032] The support frame 101 has a snap-fit ​​groove 102, a sliding sleeve 103 is embedded in the snap-fit ​​groove 102, a clamping block 111 is snapped into the snap-fit ​​groove 102, and a fixing hole 112 is provided on the clamping block 111. The support frame 101 is fixed to the clamping block 111 by the snap-fit ​​groove 102 and bolts 104.

[0033] The clamping block 111 has an integrally formed connecting beam 113 on the side away from the support frame 101. One side of the connecting beam 113 is fixed to the engineering vehicle 400, which facilitates the connection and fixation of the support frame 101 and the engineering vehicle 400, and facilitates on-site construction operations and disassembly and transfer.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
