Description

Technical Field

[0001] This utility model belongs to the field of highway construction and maintenance technology, specifically a repair material compaction machine used for highway construction and maintenance. Background Technology

[0002] As a core infrastructure of the transportation system, highways are prone to damage such as cracks, potholes, loosening, and subsidence during long-term service due to repeated vehicle loads, natural environmental influences, construction defects, and untimely maintenance. If these defects are not repaired in time, they will gradually expand and affect the safety and service life of highways. Therefore, road surface repair is a key aspect of highway construction and maintenance.

[0003] Currently, the commonly used compaction equipment for road repair materials in highway construction and maintenance is mainly divided into two categories: one is large tracked or wheeled rollers, which have the advantages of high compaction efficiency and high pressure, and are suitable for large-area road repair or compaction after overall paving. However, the equipment is large in size and inconvenient to turn, making it unsuitable for small-scale, fine-tuned repair scenarios. Moreover, the equipment purchase and maintenance costs are high, making it less economical for small-scale maintenance projects. The other category is small handheld compaction tools, which have a certain degree of flexibility, but rely on manual operation, resulting in high labor intensity, uneven compaction pressure, difficulty in ensuring the consistency of compaction of repair materials, and low operating efficiency, failing to meet the needs of large-scale maintenance construction. Furthermore, the above-mentioned compaction equipment cannot be adjusted during use and can only be used for compaction of fixed road sections. When compacting repair materials on parallel roads, multiple compaction operations are required, and the compaction route cannot be adjusted according to the road section maintenance.

[0004] Therefore, a repair material compaction machine for highway construction and maintenance is proposed to address the above problems. Utility Model Content

[0005] To address the problem mentioned in the background art of the inability to adjust the compaction route according to road section maintenance, this utility model provides a repair material compaction construction machine for highway construction and maintenance, which has the advantage of being able to be adjusted to the corresponding compaction section according to the compaction requirements of the road section.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a compaction machine for road construction and maintenance, comprising a compaction roller, a transverse shaft passing through the interior of the compaction roller, a circular hole inside the transverse shaft, a damping rod fixedly installed inside the circular hole of the transverse shaft, a clamping frame fixedly installed at the other end of the damping rod and slidably disposed with the transverse shaft, the clamping frame being in contact with the compaction roller, and a hydraulic telescopic shaft rotatably disposed via a coupling on the other side of the compaction roller, the other end of the hydraulic telescopic shaft being fixed to the transverse shaft.

[0007] Preferably, an installation frame is interference-fitted to the outer side of the horizontal axis, and the horizontal axis passes through the installation frame. An anti-collision beam is welded and fixed to the left side of the installation frame.

[0008] Preferably, a spring is sleeved on the outer side of the damping rod, and the spring is located between the damping rod and the clamping frame.

[0009] Preferably, both ends of the clamping frame are equipped with omnidirectional wheels that rotate inside, and the omnidirectional wheels are in contact with the surface of the rolling roller.

[0010] Preferably, both ends of the horizontal shaft are fitted with positioning ends that fit with the mounting frame, and the end face of the positioning end is provided with a fastening bolt that is spirally arranged with the horizontal shaft.

[0011] Preferably, the surface of the horizontal shaft has a horizontal groove that penetrates the circular hole, and the two sides of the clamping frame are located inside the horizontal groove.

[0012] Preferably, a guide frame is fixedly provided on the inner wall of the mounting frame, an inclined plate is inserted into the inside of the guide frame, and a scraper is fixedly provided at the end of the inclined plate, and the scraper is in contact with the rolling roller.

[0013] Preferably, the top of the inclined plate is fixedly provided with a positioning ring that fits against the guide frame, and the interior of the positioning ring is provided with a screw that is spirally arranged with the inner wall of the mounting frame.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model, through the structural design of two rolling rollers on the outer side of the horizontal axis, overcomes the limitations of existing large road rollers and small handheld rolling tools that can only operate in a fixed mode. This machine can adjust the rolling route, which can adjust the rolling width or working trajectory according to the spacing requirements of parallel road repairs, avoiding repeated rolling of the same area. It can also accurately plan the rolling route for the maintenance needs of different road sections, solving the problem of fixed road section rolling of traditional equipment and improving the ability of refined operation.

[0016] 2. Through the scraper structure design, this utility model can remove the surface repair material carried up by the rolling roller during the rolling process, thereby avoiding the problem of the repair material being carried away and wasted in the rolled section.

[0023] 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.

[0024] like Figures 1 to 5 As shown, this utility model provides a compaction machine for road construction and maintenance, including a compaction roller 6. A horizontal shaft 3 is inserted through the interior of the compaction roller 6. A circular hole is opened inside the horizontal shaft 3. A damping rod 7 is fixed inside the circular hole of the horizontal shaft 3. A clamping frame 9 is fixed at the other end of the damping rod 7 and is slidably arranged with the horizontal shaft 3. The clamping frame 9 is in contact with the compaction roller 6. A hydraulic telescopic shaft 10 is attached to the other side of the compaction roller 6 and is rotatably arranged through a coupling. The other end of the hydraulic telescopic shaft 10 is fixed to the horizontal shaft 3. The compaction roller 6 is moved and its position is adjusted by the hydraulic telescopic shaft 10.

[0025] Specifically, an installation frame 2 is provided on the outer side of the horizontal axis 3 with an interference fit, and the horizontal axis 3 passes through the installation frame 2. An anti-collision beam 1 is welded and fixed on the left side of the installation frame 2 to strengthen the front-end protection of the repair material construction machinery.

[0026] A spring 8 is fitted on the outer side of the damping rod 7. The spring 8 is located between the damping rod 7 and the clamping frame 9, and provides a buffering effect through the spring 8.

[0027] Both ends of the clamping frame 9 are equipped with rotatable casters 11, and the casters 11 are attached to the surface of the rolling roller 6 to reduce the friction between the clamping frame 9 and the rolling roller 6.

[0028] Both ends of the horizontal shaft 3 are fitted with positioning ends 4 that fit with the mounting frame 2. The end face of the positioning end 4 is provided with fastening bolts 5 that are spirally arranged with the horizontal shaft 3 to facilitate quick installation.

[0029] A transverse groove 12 is formed on the surface of the horizontal shaft 3, penetrating the circular hole. The two sides of the clamping frame 9 are located inside the transverse groove 12. A guide frame 13 is fixedly installed on the inner wall of the mounting frame 2. An inclined plate 14 is inserted into the inside of the guide frame 13. A scraper 16 is fixed at the end of the inclined plate 14 and fits against the rolling roller 6. A positioning ring 15 is fixed at the top of the inclined plate 14 and fits against the guide frame 13. A screw 17 is threaded through the inside of the positioning ring 15 and spirally arranged against the inner wall of the mounting frame 2. The pressure is adjusted by driving the rolling roller 6 through the extension and retraction of the hydraulic telescopic shaft 10, in conjunction with the damping rod 7 and spring. The buffer structure composed of 8 components offsets pressure fluctuations caused by uneven road surfaces in real time during compaction, ensuring uniform compaction pressure. The horizontal shaft 3, as the core support component, is rigidly fixed to the mounting frame 2 through the cooperation of the positioning end 4 and the fastening bolt 5. At the same time, the horizontal groove 12 provides sliding guidance for the clamping frame 9, so that the universal wheel 11 always fits against the surface of the compaction roller 6 to assist in stable rotation. The inclined plate 14 in the guide frame 13 is fixed to the positioning ring 15 through the screw 17, which drives the scraper 16 to fit tightly against the compaction roller 6, realizing real-time cleaning of repair material residue during compaction and avoiding material accumulation that affects the compaction effect.

[0030] Working principle and process:

[0031] Confirm that the interference fit between the mounting frame 2 and the horizontal shaft 3 is secure, and that there are no cracks at the weld of the anti-collision beam 1; rotate the fastening bolt 5 to ensure that the positioning end 4 stably limits the horizontal shaft 3 within the mounting frame 2, preventing axial movement during operation; check the elastic performance of the damping rod 7 and the spring 8 to ensure that the clamping frame 9 can slide flexibly along the circular hole of the horizontal shaft 3, and that the universal wheel 11 and the surface of the roller 6 are in close contact without gaps; activate the hydraulic telescopic shaft 10 through the controller, and use its telescopic action to adjust the initial pressure of the roller 6, pushing the roller 6 on the outside of the horizontal shaft 3 to move and adjust it to the construction section, pushing the inclined plate 14 to slide along the guide frame 13, so that the scraper 16 and the surface of the roller 6 maintain appropriate contact, ensuring cleaning To avoid excessive friction and damage to the rollers, tighten the fixing and positioning ring 15 to fix the scraper 16 and maintain its cleaning position. Connect the equipment power supply and start the drive motor (usually an existing electric motor construction machine, fixed by bolts or other structural connections). Drive the compaction roller 6 to idle and observe whether its rotation is smooth, whether the casters 11 rotate synchronously, and whether the scraper 16 can effectively scrape off simulated residual material from the roller surface. Test the protective performance of the anti-collision beam 1 to ensure that it can effectively avoid the risk of collision with obstacles such as curbs when the equipment moves. Move the machine to the starting point of the repair area, and adjust the equipment posture according to the compaction route plan so that the compaction roller 6 is aligned with the first repair area and the anti-collision beam 1 faces the front of the direction of travel. The drive system is activated, and the machine travels along the planned route. The compaction roller 6 compacts the repair material. During travel, if a road surface protrusion is encountered, the reaction force on the compaction roller 6 is transmitted to the spring 8 and damping rod 7 through the clamping frame 9. The spring 8 contracts to buffer the impact force, and the damping rod 7 suppresses the high-frequency rebound of the spring 8, maintaining the stable forward movement of the compaction roller 6. The casters 11 rotate synchronously with the compaction roller 6 to prevent the roller 6 from swaying and to ensure the flatness of the compacted surface. The scraper 16 continuously adheres to the roller surface during compaction, scraping away any adhering repair material to prevent residual material from accumulating and affecting subsequent compaction. If it is necessary to switch to another repair area on a parallel road, the hydraulic telescopic shaft 10 is adjusted via the controller. In its extended state, the roller 6 is pushed to the outside of the horizontal axis 3, allowing it to precisely align with the new area. This eliminates the need for repeated movement of equipment, enabling the compaction of multiple parallel areas and reducing redundancy. After compacting all repair areas, the drive motor and power are turned off, and the machine is moved to a flat parking area to lift the roller 6 off the ground, preventing deformation from prolonged pressure. The screw 17 on the positioning ring 15 is loosened, and the inclined plate 14 and scraper 16 are removed. The residual repair material on the scraper 16 is cleaned. The working condition of the damping rod 7 and spring 8 is checked, and they are replaced promptly if deformation or loss of elasticity occurs. All loose bolts are tightened to ensure reliable connections of the positioning end 4, fastening bolts 5, etc., and the machine is ready for the next operation.
