Description

Technical Field

[0001] This utility model relates to the technical field of road construction equipment, specifically a rapid compaction device for road construction in cold regions. Background Technology

[0002] In the field of road maintenance, timely repair of road potholes is a key link in ensuring road traffic safety and service life. Asphalt is usually used to fill road potholes. After the asphalt is filled into the pothole, it needs to be compacted by a road construction compaction device to ensure that the asphalt is tightly bonded to the original road surface and improve the structural strength and durability of the repaired area.

[0003] In cold regions or low-temperature environments, the freshly filled asphalt material cools and solidifies rapidly due to the low ambient temperature, causing a sharp decrease in its fluidity and a rapid increase in its hardness. Under these conditions, ordinary road construction compaction devices are unable to effectively level and compact the partially solidified asphalt. The plasticity of the solidified asphalt is reduced, and uneven stress is prone to occur during the leveling process, resulting in an uneven repair surface and affecting the repair quality. This forces construction workers to complete the leveling and compaction operations in a very short time, which not only increases the difficulty of the operation but also easily leads to unstable construction quality due to hasty operation. The above problems not only reduce the efficiency and quality of road repair in cold regions but may also cause premature secondary damage to the repaired area, increasing the later maintenance costs and posing a potential threat to road traffic safety. Utility Model Content

[0004] The purpose of this invention is to provide a rapid compaction device for road construction in cold regions. It has the advantages of effectively delaying the cooling and solidification of asphalt, strong adaptability and convenient operation, and solves the problem of difficulty in flattening asphalt due to rapid cooling and solidification during road repair in cold regions in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A rapid compaction device for road construction in cold regions includes a load-bearing component. The load-bearing component includes a load-bearing box with movable wheels installed at the four corners of its lower end. The outer walls of the load-bearing box have grooves. An insulation component is installed on the outer wall of the load-bearing box. The insulation component includes sliders slidably installed within the grooves. A protective cover is fixedly connected to the ends of the sliders that are far apart from each other. The inner wall of the protective cover fits against the outer wall of the load-bearing box. Equally spaced bonding components are installed at the lower edge of the protective cover. Each bonding component includes a fixed rod fixed to the lower edge of the protective cover. A movable rod is slidably installed on the inner wall of the fixed rod. The bonding component also includes a spring fixed to the upper end of the movable rod, with the upper end of the spring fixed to the upper inner wall of the fixed rod. An insulation film is fixed to the outer wall of the protective cover, with the lower end of the insulation film fixed to the lower end of the movable rod. The insulation component also includes a heating plate fixed to the upper inner wall of the protective cover. A flattening component is installed at the lower end of the load-bearing component and is located inside the protective cover.

[0007] Preferably, the right end wall of the carrier box is provided with a symmetrical groove, and the lower inner wall edge of the carrier box is fixed with a symmetrical electric cylinder. The output end of each electric cylinder is fixed with a support block, which passes through the groove and is fixed to the inner wall of the protective cover.

[0008] It is worth noting that the output end of the electric cylinder can drive the support block to move up and down along the inner wall of the tank, thereby driving the protective cover to move up and down along the outer wall of the carrier box, so that the lower end of the protective cover is in contact with the ground to insulate the lower end of the carrier box, or drive the protective cover to rise to facilitate the movement of the carrier box.

[0009] Preferably, the inner walls of the left and right ends of the bearing box are provided with slots, and the flattening assembly includes a lead screw. The two ends of the lead screw are rotatably installed in the slots of the left and right end walls of the bearing box through bearings, and the outer wall of the bearing is fixed to the inner wall of the slot.

[0010] Preferably, a movable seat is threaded onto the outer wall of the lead screw, and a fixed sleeve with symmetrical front and rear ends is fixedly connected to the lower end of the movable seat. A groove with symmetrical front and rear ends is opened through the lower end wall of the bearing box, and the inner wall of the groove fits against the outer wall of the fixed sleeve.

[0011] It is worth noting that the slot can support and limit the lead screw, the bearing can limit and fix the lead screw and ensure the stability of the lead screw rotation, and the rotation of the lead screw can drive the movable seat to move left and right. The fixed sleeve slides along the inner wall of the slot, further improving the stability of the movable seat movement.

[0012] Preferably, a fixing block is slidably installed on the inner wall of the fixing sleeve, and a shock absorber is fixedly connected to the upper end of the fixing block. The upper end of the shock absorber is fixedly connected to the upper inner wall of the fixing sleeve. The flattening assembly also includes a flattening roller fixedly connected to the lower end of the fixing block.

[0013] It is worth noting that the fixing block can be fixed by the fixing sleeve, thereby fixing the flattening roller under the movable seat, so that the movable seat can drive the flattening roller to move left and right, which can press and flatten the filling asphalt at the bottom of the bearing box. The shock absorber can buffer the vibration generated by the flattening roller and reduce the impact of vibration on the bearing box.

[0014] Preferably, the inner walls of the left and right ends of the carrier box are also fixedly connected to slide rods, and the left and right ends of the movable seat are provided with sliding holes. The inner walls of the sliding holes are in contact with the outer walls of the slide rods. A servo motor is installed at the right end of the carrier box, and the output end of the servo motor is connected to the rotating shaft of the lead screw.

[0015] It is worth noting that the movable seat can move left and right along the outer wall of the slide bar by means of the sliding rod and the sliding hole, which can further improve the stability of the movable seat movement. The output end of the servo motor can drive the lead screw to rotate, thereby driving the movable seat to move left and right, and driving the pressing roller to press and flatten the filled asphalt.

[0016] Preferably, the carrier component also includes a protective cover fixed to the upper end of the carrier box, and a controller is installed on the upper end of the protective cover.

[0017] It is worth noting that the protective cover can protect the equipment inside the carrier box from damage, and the controller can operate the equipment installed inside the carrier box.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] This invention utilizes movable wheels to facilitate the movement of the carrier box, allowing it to be moved to the area where asphalt is filled. An electric cylinder pushes the protective cover downwards along the inner wall of the chute, causing the movable rod to conform to the ground. A spring pushes the movable rod to conform to and adapt to the ground contour, thus ensuring that the lower end of the insulation film fits and adheres tightly to the ground, reducing gaps between the insulation film and the ground. The insulation film, together with the protective cover, insulates the asphalt filled at the lower end of the carrier box. Furthermore, the use of a heating plate increases the temperature inside the protective cover, slowing down the asphalt's solidification and maintaining a temperature conducive to shaping. Finally, a flattening component compacts and flattens the asphalt, enabling rapid asphalt compaction and road repair in cold regions while ensuring the quality of asphalt compaction.

Detailed Implementation

[0026] 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.

[0027] To address the difficulty in compacting asphalt during rapid cooling and solidification in cold-region road repair using existing technologies, the following technical solution is provided. Please refer to [link / reference]. Figures 1-5 ;

[0028] A rapid compaction device for road construction in cold regions includes a load-bearing component. The load-bearing component includes a load-bearing box 101. Playing wheels 104 are installed at the four corners of the lower end of the load-bearing box 101. Slide grooves 108 are formed on the outer walls of the front and rear ends of the load-bearing box 101. An insulation component is installed on the outer wall of the load-bearing box 101. The insulation component includes sliders 202 slidably installed within the slide grooves 108. Protective covers 201 are fixedly connected to the ends of the sliders 202 that are far apart from each other. The inner wall of the protective cover 201 is in contact with the outer wall of the load-bearing box 101. Equally spaced bonding components are installed at the lower edge of the protective cover 201. The component includes a fixing rod 401 fixed to the lower edge of the protective cover 201, a movable rod 403 slidably mounted on the inner wall of the fixing rod 401, a spring 402 fixed to the upper end of the movable rod 403, the upper end of the spring 402 fixed to the upper inner wall of the fixing rod 401, an insulation film 205 fixed to the outer wall of the protective cover 201, the lower end of the insulation film 205 fixed to the lower end of the movable rod 403, an insulation component including an electric heating plate 204 fixed to the upper inner wall of the protective cover 201, and a flattening component installed at the lower end of the bearing component, the flattening component being located inside the protective cover 201.

[0029] The movable wheel 104 facilitates the movement of the carrier box 101, allowing it to be moved to the area filled with asphalt. The protective cover 201 is then pushed downwards along the inner wall of the chute 108, causing the movable rod 403 to conform to the ground. The spring 402 pushes the movable rod 403 to conform to and adapt to the ground contour, thus ensuring the lower end of the insulation film 205 fits and adheres tightly to the ground, reducing gaps between the insulation film 205 and the ground. The insulation film 205, together with the protective cover 201, insulates the asphalt filled at the lower end of the carrier box 101. Furthermore, the heating plate 204 raises the temperature inside the protective cover 201, slowing down asphalt solidification and maintaining a temperature conducive to shaping. The flattening component then compacts and flattens the asphalt, enabling rapid asphalt compaction in cold regions and ensuring the quality of asphalt compaction.

[0030] Please see Figure 3 The right end wall of the carrier box 101 is provided with a symmetrical groove 109. The lower inner wall edge of the carrier box 101 is fixed with a symmetrical electric cylinder 110. The output end of each electric cylinder 110 is fixed with a support block 203. The support block 203 passes through the groove 109 and is fixed to the inner wall of the protective cover 201. The output end of the electric cylinder 110 can drive the support block 203 to move up and down along the inner wall of the groove 109, thereby driving the protective cover 201 to move up and down along the outer wall of the carrier box 101, so that the lower end of the protective cover 201 is in contact with the ground to keep the lower end of the carrier box 101 warm, or drive the protective cover 201 to rise, so as to facilitate the movement of the carrier box 101.

[0031] The support assembly also includes a protective cover 102 fixed to the upper end of the support box 101, and a controller 103 is installed on the upper end of the protective cover 102; the protective cover 102 can protect the equipment inside the support box 101 to prevent damage to the equipment, and the controller 103 can control the equipment installed inside the support box 101.

[0032] Please see Figure 5 The bearing box 101 has slots 107 on the inner walls of its left and right ends. The flattening assembly includes a lead screw 301. The two ends of the lead screw 301 are rotatably installed in the slots 107 on the left and right end walls of the bearing box 101 via bearings. The outer wall of the bearing is fixed to the inner wall of the slot 107. A movable seat 302 is threaded onto the outer wall of the lead screw 301. A symmetrical fixed sleeve 304 is fixed to the lower end of the movable seat 302. A symmetrical groove 105 is opened through the lower end wall of the bearing box 101. The inner wall of the groove 105 fits against the outer wall of the fixed sleeve 304. The slots 107 can support and limit the lead screw 301. The bearings can limit and fix the lead screw 301 and ensure the stability of the rotation of the lead screw 301. The rotation of the lead screw 301 can drive the movable seat 302 to move left and right. The fixed sleeve 304 slides along the inner wall of the groove 105, further improving the stability of the movement of the movable seat 302.

[0033] A fixing block 305 is slidably installed on the inner wall of the fixing sleeve 304. A shock absorber 306 is fixedly connected to the upper end of the fixing block 305. The upper end of the shock absorber 306 is fixedly connected to the upper inner wall of the fixing sleeve 304. The flattening assembly also includes a flattening roller 307 fixedly connected to the lower end of the fixing block 305. The fixing block 305 can be fixed by the fixing sleeve 304, thereby fixing the flattening roller 307 below the movable seat 302, so that the movable seat 302 can drive the flattening roller 307 to move left and right, which can press and flatten the filling asphalt at the lower end of the bearing box 101. The shock absorber 306 can buffer the vibration generated by the flattening roller 307 and reduce the impact of vibration on the bearing box 101.

[0034] The inner walls of the left and right ends of the bearing box 101 are also fixed with slide rods 106. The left and right ends of the movable seat 302 are provided with sliding holes 303. The inner wall of the sliding hole 303 is in contact with the outer wall of the slide rod 106. The right end of the bearing box 101 is equipped with a servo motor 111. The output end of the servo motor 111 is connected to the rotating shaft of the lead screw 301. By using the slide rod 106 in conjunction with the sliding hole 303, the movable seat 302 can move left and right along the outer wall of the slide rod 106, which can further improve the stability of the movement of the movable seat 302. The output end of the servo motor 111 can drive the lead screw 301 to rotate, thereby driving the movable seat 302 to move left and right, and driving the pressing roller 307 to press and flatten the filling asphalt.

[0035] Working principle: During the construction preparation and equipment movement phase, the four movable wheels 104 at the lower corners of the carrier box 101 are used to move the carrier box 101 to the construction area where the road surface needs to be filled with asphalt. The protective cover 102 can protect the electric cylinder 110, servo motor 111 and other equipment inside the carrier box 101, preventing damage from external collisions during the movement. After the equipment arrives at the construction area, the controller 103 restarts the electric cylinder 110, controlling its output end to drive the support block 203 to move downward along the groove 109, and simultaneously drive the protective cover 201 to slide down the slide 108 via the slider 202. During this process, the movable rod 403 of the component attached to the lower edge of the protective cover 201 first contacts the ground, and as the protective cover 201 continues to move downward... The movable rod 403 slides upward on the inner wall of the fixed rod 401 and compresses the spring 402. The spring 402 pushes the movable rod 403 to always keep it close to the ground through its own elastic deformation, adapting to the ground contour of the construction area. The insulation film 205, which is fixed to the lower end of the movable rod 403, is synchronously attached to the ground with the movable rod 403, reducing the gap between the insulation film 205 and the ground. This allows the protective cover 201 and the insulation film 205 to form a closed insulation space at the lower end of the bearing box 101, covering the filled asphalt inside. Then, the electric heating plate 204 on the upper inner wall of the protective cover 201 is turned on by the controller 103. The electric heating plate 204 releases heat to raise the temperature in the insulation space, slowing down the solidification speed of the asphalt in the cold environment, and ensuring that the asphalt always remains in a state that is easy to shape.

[0036] The device uses a built-in rechargeable battery as the main power supply, and is also equipped with an external power interface to meet the needs of long-term operation. The controller 103 establishes electrical connections with the electric cylinder 110, servo motor 111, electric heating plate 204 and other electrical equipment through dedicated cables to form a closed-loop control circuit, ensuring that the controller 103 can stably output electrical signal commands to achieve precise start-up and operation adjustment of each device.

[0037] During the asphalt compaction and flattening stage, the servo motor 111 on the right end of the bearing box 101 is started by the controller 103. The output end of the servo motor 111 drives the lead screw 301 to rotate. When the lead screw 301 rotates, the movable seat 302, which is threaded to its outer wall, moves stably left and right along the slide rods 106 on the inner walls of the left and right ends of the bearing box 101 through the sliding holes 303 at both ends. At the same time, the fixed sleeve 304 at the lower end of the movable seat 302 slides synchronously along the groove 105 on the lower end wall of the bearing box 101, further improving the stability of the movement of the movable seat 302. The fixed block 305 on the inner wall of the fixed sleeve 304 moves with the movable seat 302, driving the flattening roller 307 at the lower end of the fixed block 305 to roll on the asphalt surface in the heat preservation space, thus compacting the asphalt. The asphalt is pressed and flattened. During this process, an elastic rubber scraper is provided on the side of the fixed block 305 near the flattening roller 307. The edge of the scraper is in close contact with the outer wall of the flattening roller 307. When the flattening roller 307 rolls, the scraper can scrape off the asphalt adhering to its surface in real time. The scraper is detachable, which is convenient for regular cleaning and replacement, ensuring that the flattening roller 307 is always kept clean. The vibration of the flattening roller 307 caused by the uneven road surface is transmitted to the shock absorber 306 in the fixed sleeve 304 through the fixed block 305. The shock absorber 306 weakens the vibration through its own buffering effect, avoiding the vibration from affecting the bearing box 101 and the internal equipment, and ensuring that the flattening roller 307 always performs the asphalt pressing and flattening operation stably.

[0038] After the construction is completed and the equipment is transferred, the electric heating plate 204 and the servo motor 111 are turned off in sequence by the controller 103. Then the electric cylinder 110 is started to drive the protective cover 201 to rise and reset. Finally, the carrier box 101 is pushed to move to the next construction area or the designated storage location through the movable wheel 104, thus completing the compaction construction process of asphalt repair in cold regions.
