Description
Technical Field
[0001] This utility model relates to the field of road engineering construction technology, specifically to an asphalt paving and compaction device for road and bridge construction. Background Technology
[0002] The construction or reconstruction of highways is determined based on highway network planning. A country's highway construction should take into account the role and status of highways in intermodal transport, in conjunction with railways, waterways, and aviation, and formulate a national highway network plan classified by grade according to its political, military, economic, and people's livelihood needs, combined with geographical conditions. From an administrative perspective, highways are generally divided into four grades: national highways, provincial highways, county highways, and township highways. Therefore, paving and compaction devices are needed in road construction projects to improve the practicality of roads.
[0003] Currently, Chinese utility model patent CN220927416U discloses a road construction paving and compaction device, including a water tank fixedly connected to the upper part of the main body, a conveying pipe fixedly connected to the lower end of the water tank for flow, a water storage box fixedly connected to the lower end of the conveying pipe for water storage, and a nozzle for water atomization inserted into the side of the water storage box. This road construction paving and compaction device, through the arrangement of the water tank, conveying pipe, water storage box, and nozzle, allows workers to easily add an anti-adhesion release agent to the water tank and then spray it onto the outer surface of the compaction device through the nozzle. This solves the problem of asphalt sticking to the surface of the compaction device, which affects the paving and compaction of the asphalt pavement. Simultaneously, when applying the anti-adhesion treatment to the compaction device, the atomized water can slightly cool the newly paved and compacted asphalt pavement, preventing cracking of the pavement due to sudden cooling.
[0004] Based on the search of the aforementioned patents and the findings of existing equipment, while the aforementioned equipment can solve the problem that asphalt may stick to the outer surface of the compaction device when laying and compacting asphalt at high temperatures, thus affecting the laying and compaction of the road surface and making it inconvenient for workers to assemble and disassemble the laying and compaction device from the main equipment, thereby affecting work efficiency, the spraying of anti-sticking release agent has some effect during use, but there are still residues. The asphalt residue on the roller surface is difficult to clean, and if it is not cleaned in time, it will accumulate more and more, not only affecting the performance of the roller, but also potentially polluting the road surface in subsequent construction. Utility Model Content
[0005] To address the problems mentioned in the background art, the purpose of this utility model is to provide an asphalt paving and compaction device for road and bridge construction, which has the advantage of improving the cleaning effect. It solves the problem that although spraying anti-sticking release agent has a certain effect, there are still residues. The asphalt residue on the roller surface is difficult to clean. If it is not cleaned in time, it will accumulate more and more, which will not only affect the performance of the roller, but may also pollute the road surface in subsequent construction.
[0006] To achieve the above objectives, this utility model provides the following technical solution: an asphalt paving and compaction device for road and bridge construction, comprising a main frame, a rotating shaft, and rollers. The rotating shaft is movably connected to the inner wall of the main frame, and the rollers are fixedly installed on the inner side of the rotating shaft. Movable seats are fixedly installed on both sides of the top of the main frame. A rotating roller is movably connected to the inner wall of the movable seat through a bearing. A brush is fixedly connected to the surface of the rotating roller. The number of brushes is arranged in several groups and is distributed in a ring at equal distances. A transmission assembly is fixedly connected to both sides of the rotating roller, and an auxiliary cleaning assembly is provided on the left side of the movable seat.
[0007] In a preferred embodiment of this invention, the transmission assembly includes a small transmission wheel, which is fixedly connected to both sides of the rotating roller. Large transmission wheels are fixedly connected to both sides of the rotating shaft, and the large and small transmission wheels are connected by a transmission belt.
[0008] As a preferred embodiment of this utility model, the auxiliary cleaning component includes a groove, which is formed on the left side of the movable seat. An installation plate is movably connected to the inner wall of the groove, and a rubber scraper is fixedly connected to the inner wall of the installation plate by bolts. The left side of the rubber scraper is in contact with the surface of the roller.
[0009] As a preferred embodiment of this invention, both the small and large transmission wheels are fitted with protective covers, which are fixedly installed on both sides of the main frame.
[0010] As a preferred embodiment of this utility model, a tension spring is provided inside the groove, one end of the tension spring is fixedly connected to the bottom of the inner wall of the groove, and the other end of the tension spring is fixedly connected to both sides of the bottom of the mounting plate.
[0011] As a preferred embodiment of this utility model, a limiting groove is provided on both sides of the inner wall of the groove, and a ball bearing is movably connected to the inner wall of the limiting groove, and the ball bearing is movably embedded in the surface of the mounting plate.
[0012] As a preferred embodiment of this utility model, connecting blocks are fixedly installed on both sides of the bottom of the mounting plate, and anti-collision wheels are movably connected to both sides of the inner wall of the connecting blocks via bearings.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] 1. This utility model, by setting up a movable seat, a rotating roller, a brush, a transmission component, and an auxiliary cleaning component, can effectively enable the transmission component to drive the rotating roller to rotate the brush, thereby continuously cleaning the roller surface. Compared with a single cleaning method, it greatly improves the cleaning effect on asphalt residue on the roller surface, effectively reduces the impact of asphalt residue on roller performance, and solves the problem that although spraying anti-sticking release agent has a certain effect, there is still residue. It is difficult to clean the asphalt residue on the roller surface. If it is not cleaned in time, it will accumulate more and more, which not only affects the roller performance but may also pollute the road surface during subsequent construction. It has the advantage of improving the cleaning effect.
[0015] 2. By setting up a transmission component, this utility model can effectively drive the large transmission wheel to rotate when the roller and the shaft rotate. The large transmission wheel drives the small transmission wheel to rotate through the belt, and the small transmission wheel drives the rotating roller to rotate synchronously. This realizes automatic cleaning of the brush roller. By utilizing the power of the equipment itself, no additional power source is required, which saves energy, simplifies the structure of the device, and ensures that the cleaning work is carried out synchronously with the operation of the equipment, thereby improving the timeliness and continuity of cleaning.
[0016] 3. By setting up an auxiliary cleaning component, this utility model can effectively allow the rubber scraper to slide downwards in the groove through the mounting plate, so that the rubber scraper contacts the surface of the roller and further scrapes away the residual asphalt on the surface of the roller. The rubber scraper has a certain degree of flexibility and can conform to the surface of the roller, enhancing the cleaning effect. At the same time, the mounting plate fixes the rubber scraper with bolts, which makes it convenient to replace the rubber scraper after it wears out, ensuring the continuous effectiveness of the cleaning work.

[0021] 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.
[0022] like Figures 1 to 3 As shown, this utility model provides an asphalt paving and compaction device for road and bridge construction, including a main frame 1, a rotating shaft 2, and rollers 3. The rotating shaft 2 is movably connected to the inner wall of the main frame 1, and the rollers 3 are fixedly installed on the inner side of the rotating shaft 2. Movable seats 4 are fixedly installed on both sides of the top of the main frame 1. A rotating roller 5 is movably connected to the inner wall of the movable seat 4 through a bearing. A brush 6 is fixedly connected to the surface of the rotating roller 5. The number of brushes 6 is arranged in several groups and is distributed in a ring at equal distances. A transmission component 7 is fixedly connected to both sides of the rotating roller 5. An auxiliary cleaning component 8 is provided on the left side of the movable seat 4.
[0023] refer to Figure 1 and 2 The transmission assembly 7 includes a small transmission wheel 71, which is fixedly connected to both sides of the rotating roller 5. Large transmission wheels 72 are fixedly connected to both sides of the rotating shaft 2. The large transmission wheels 72 and the small transmission wheels 71 are connected by a transmission belt 73.
[0024] As a technical optimization of this utility model, by setting the transmission component 7, the large transmission wheel 72 can be effectively driven to rotate when the roller 3 and the rotating shaft 2 rotate. The large transmission wheel 72 drives the small transmission wheel 71 to rotate through the belt, and the small transmission wheel 71 can drive the rotating roller 5 to rotate synchronously, so that the brush 6 automatically cleans the roller 3. By utilizing the power of the equipment itself, no additional power source is required, which saves energy, simplifies the structure of the device, and ensures that the cleaning work is carried out synchronously with the operation of the equipment, thereby improving the timeliness and continuity of cleaning.
[0025] refer to Figure 2 and Figure 3 The auxiliary cleaning component 8 includes a groove 81, which is located on the left side of the movable seat 4. An installation plate 82 is movably connected to the inner wall of the groove 81. A rubber scraper 83 is fixedly connected to the inner wall of the installation plate 82 by bolts. The left side of the rubber scraper 83 is in contact with the surface of the roller 3.
[0026] As a technical optimization of this utility model, by setting the auxiliary cleaning component 8, the rubber scraper 83 can be effectively slid downward in the groove 81 through the mounting plate 82, so that the rubber scraper 83 contacts the surface of the roller 3, further scraping off the residual asphalt on the surface of the roller 3. The rubber scraper 83 has a certain degree of flexibility and can conform to the surface of the roller 3, enhancing the cleaning effect. At the same time, the mounting plate 82 fixes the rubber scraper 83 with bolts, which is convenient for replacement after the rubber scraper 83 wears out, ensuring the continuous effectiveness of the cleaning work.
[0027] refer to Figure 2 and Figure 3 The surfaces of both the small transmission wheel 71 and the large transmission wheel 72 are fitted with protective covers 9, which are fixedly installed on both sides of the main frame 1.
[0028] As a technical optimization of this utility model, by setting a protective cover 9, the surfaces of the large transmission wheel 72 and the small transmission wheel 71 can be effectively covered with a protective cover 9, which can prevent debris from entering the large transmission wheel 72 and the small transmission wheel 71 during the construction process, ensure the normal operation of the transmission component 7, and thus ensure the stable operation of the brush 6 and the roller 3.
[0029] refer to Figure 2 and Figure 3 A tension spring 10 is provided inside the groove 81. One end of the tension spring 10 is fixedly connected to the bottom of the inner wall of the groove 81, and the other end of the tension spring 10 is fixedly connected to both sides of the bottom of the mounting plate 82.
[0030] As a technical optimization of this utility model, by setting a tension spring 10, the tension spring 10 can effectively pull the mounting plate 82 so that the rubber scraper 83 always keeps in contact with the surface of the roller 3. When the surface of the roller 3 is uneven or the equipment vibrates, the tension spring 10 can play a buffering role, ensuring that the rubber scraper 83 can continuously and effectively scrape off the asphalt, and further enhance the cleaning effect.
[0031] refer to Figure 2 and Figure 3 Both sides of the inner wall of the groove 81 are provided with limiting grooves 11, and the inner wall of the limiting grooves 11 is movably connected with balls 12, which are movably embedded in the surface of the mounting plate 82.
[0032] As a technical optimization of this utility model, by setting the limiting groove 11 and the ball 12, the limiting groove 11 and the ball 12 can be effectively matched to restrict the movement direction of the mounting plate 82, so that the mounting plate 82 can only move up and down smoothly within the groove 81, avoiding the shaking of the mounting plate 82 from affecting the adhesion between the rubber scraper 83 and the roller 3 surface, ensuring that the rubber scraper 83 can scrape off the asphalt evenly, and improving the stability and reliability of cleaning.
[0033] refer to Figure 2 and Figure 3 Connecting blocks 13 are fixedly installed on both sides of the bottom of the mounting plate 82, and anti-collision wheels 14 are movably connected to both sides of the inner wall of the connecting block 13 through bearings.
[0034] As a technical optimization of this utility model, by setting the connecting block 13 and the anti-collision wheel 14, when the rubber scraper 83 is worn out, when the tension spring 10 pulls the mounting plate 82 to pull the rubber scraper 83 down, the anti-collision wheel 14 can rotate while contacting the surface of the roller 3, thus avoiding the wear caused by the tension spring 10 pulling the mounting plate 82 to collide with the roller 3.
[0035] The working principle and usage process of this utility model are as follows: In use, the roller 3 first rotates via the shaft 2, driving the main frame 1 to move. This allows the roller 3 to rotate and compact the asphalt pavement. Then, the roller 3 drives the large transmission wheel 72 to rotate. The large transmission wheel 72 is connected to the small transmission wheels 71 on both sides of the rotating roller 5 via a transmission belt 73. The rotation of the large transmission wheel 72 drives the transmission belt 73, causing the small transmission wheels 71 to drive the rotating roller 5 to rotate synchronously. Since several sets of equally spaced, circular brushes 6 are fixedly connected to the surface of the rotating roller 5, the rotation of the rotating roller 5 causes the brushes 6 to automatically clean the surface of the roller 3, removing some of the asphalt and improving the cleaning effect. Simultaneously, the rubber scraper 83 is fixed to the inner wall of the mounting plate 82 with bolts. Under the action of the tension spring 10, the rubber scraper 83 remains in contact with the roller. The roller 3 surface remains in contact, and the tension spring 10 allows the rubber scraper 83 to adhere to the surface of the roller 3. At the same time, through the limiting groove 11, it cooperates with the ball bearing 12 embedded in the surface of the mounting plate 82, restricting the mounting plate 82 to move smoothly up and down only within the groove 81, ensuring the adhesion between the rubber scraper 83 and the surface of the roller 3, so that the rubber scraper 83 can evenly scrape off the residual asphalt on the surface of the roller 3, further improving the cleaning effect of the roller 3 surface. When the rubber scraper 83 wears out due to long-term use, the tension spring 10 will pull the mounting plate 82 to pull the rubber scraper 83 down. At this time, the anti-collision wheel 14 on the bottom connecting block 13 of the mounting plate 82 will contact the surface of the roller 3 and rotate, avoiding direct collision between the mounting plate 82 and the roller 3, reducing component wear. When the rubber scraper 83 is worn to the point of being unusable, the rubber scraper 83 can be disassembled and replaced by bolts.
[0036] In summary, this asphalt paving and compaction device for road and bridge construction, by setting up a movable seat 4, a rotating roller 5, a brush 6, a transmission component 7, and an auxiliary cleaning component 8, can effectively enable the transmission component 7 to drive the rotating roller 5 to rotate the brush 6, thereby continuously cleaning the surface of the roller 3. Compared with a single cleaning method, it greatly improves the cleaning effect on asphalt residue on the surface of the roller 3, effectively reduces the impact of asphalt residue on the performance of the roller 3, and solves the problem that although spraying anti-sticking release agent has a certain effect, there is still residue. It is difficult to clean the asphalt residue on the roller surface. If it is not cleaned in time, it will accumulate more and more, which will not only affect the performance of the roller, but may also pollute the road surface during subsequent construction.
