Description

Technical Field

[0001] This utility model relates to the field of road construction machinery technology, specifically a combined roadbed compaction and leveling operation device. Background Technology

[0002] The combined roadbed compaction and leveling operation device is a core construction equipment for infrastructure projects such as highways and railways. It integrates roadbed leveling and compaction, and simultaneously completes the leveling and compaction reinforcement of the roadbed, saving the time of equipment switching in traditional processes and greatly improving construction efficiency. This device achieves efficient coordination of roadbed treatment by precisely controlling the leveling blades and the hydraulic power roller. During operation, the leveling blades first quickly smooth the unevenness of the roadbed surface to ensure that the flatness meets the standard. Then, the hydraulic power roller is started simultaneously to compact the smoothed roadbed, allowing the leveling and compaction processes to be seamlessly connected, which greatly improves construction efficiency. However, dust is easily generated during compaction operations, especially in dry environments. Dust can obstruct the operator's view, increase operational safety hazards, and cause material waste. At the same time, the cohesion between particles of dry subgrade material is weak, and subsequent compaction can easily result in localized loosening, making it difficult to achieve the specified compaction degree, which directly affects the overall stability of the subgrade. Utility Model Content

[0003] The purpose of this invention is to provide a combined roadbed compaction and leveling device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A combined roadbed compaction and leveling operation device includes a cab, a power control system is fixedly installed on one side of the cab, and a bracket is fixedly connected to the other side of the cab. The bottom ends of the power control system and the bracket are both fixedly connected to a drive structure. The bracket is ball-hinged to a movable frame on the side of the support closest to the cockpit, and a scraper blade is fixedly connected to the bottom end of the movable frame. The power control system is movably connected to a mobile frame on the side away from the cockpit, and a hydraulic power roller is rotatably connected to the inner cavity of the mobile frame via a pin. A spraying assembly is fixedly installed at the top of the mobile frame, and a cleaning assembly is fixedly installed on the inner wall of the mobile frame.

[0005] As a further embodiment of this utility model, the spraying assembly includes a diversion pipe, which is installed on the top of the movable frame. Spray pipes are fixedly connected to both sides of the diversion pipe, and multiple spray heads are fixedly connected to the outer walls of both sets of spray pipes.

[0006] As a further embodiment of this utility model, a movable shaft is slidably installed in the inner cavity of the spray head, a baffle plate is fixedly sleeved on the outer wall of the movable shaft, and four sets of expansion plates are rotatably connected to the outer wall of the spray head through pins.

[0007] As a further embodiment of this utility model, the cleaning component includes a scraper, which is fixedly installed on the inner wall of the movable frame. A rotating shaft is rotatably installed in the inner cavity of the scraper, and multiple sets of claws are fixedly sleeved on the outer wall of the rotating shaft.

[0008] As a further embodiment of this utility model, a ramp plate is fixedly connected to the side of the scraper away from the hydraulic power roller, and a collection box is fixedly connected to one side of the ramp plate.

[0009] As a further embodiment of this utility model, electric push rods are rotatably mounted on both sides of the bracket via pins, and the bottom end of the electric push rods is hinged to the movable frame ball joint.

[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. When this utility model is used, the problem of dust and material adhesion during compaction is solved by spraying components. By spraying water to dry roadbed materials, the moisture content of the materials is increased to enhance the adhesion between particles. This not only avoids dust obstructing the view and eliminating safety hazards, but also reduces material loss. At the same time, the surface of the hydraulic power roller is flushed to help clean the adhered materials, creating good conditions for subsequent compaction, achieving the specified compaction degree, and ensuring the stability of the roadbed.

[0011] 2. When using this utility model, the surface of the hydraulic power roller can be kept clean through the cleaning component. The scraper directly scrapes off the roadbed material adhering to the outer wall of the hydraulic power roller, and the claw assists in cleaning the residual material, avoiding the accumulation of material that affects the compaction effect. The scraped waste is collected in a concentrated manner to prevent the waste from scattering and polluting the construction environment or mixing into the roadbed, ensuring continuous and stable compaction operation and guaranteeing the compaction quality and overall stability of the roadbed.

[0018] 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.

[0019] Please see Figure 1 , Figure 2 , Figure 3 In this embodiment of the utility model, a roadbed compaction and leveling combined operation device includes a cab 1, a power control system 2 for providing power support is fixedly installed on one side of the cab 1, and a bracket 3 is fixedly connected to the other side of the cab 1. The bottom ends of the power control system 2 and the bracket 3 are both fixedly connected to a drive structure 4. A movable frame 5 is ball-hinged on the side of the bracket 3 closest to the cockpit 1. A scraper blade 6 is fixedly connected to the bottom of the movable frame 5. A movable frame 7 is movably connected on the side of the power control system 2 away from the cockpit 1. A hydraulic power roller 8 is rotatably connected to the inner cavity of the movable frame 7 through a pin. The top of the mobile frame 7 is fixedly equipped with a spraying component 9, which is used to spray water on the roadbed material to avoid dust, while increasing the adhesion between the roadbed material particles and improving the roadbed compaction effect. The inner wall of the mobile frame 7 is fixedly equipped with a cleaning component 10, which is used to remove the roadbed material adhering to the surface of the hydraulic power roller 8. It should be noted that sensors are fixedly installed on the inner walls of both the leveling blade 6 and the hydraulic power roller 8 to collect data on the flatness and compaction of the roadbed in real time. The data is then fed back to the control system to precisely adjust the leveling angle and rolling pressure, reduce human error, and ensure that the compaction effect meets the standards (specifically, the sensors are existing technology and will not be described in detail here).

[0020] Please see Figure 3 , Figure 4 The spraying assembly 9 includes a diversion pipe 901, which is installed on the top of the movable frame 7. Spray pipes 902 are fixedly connected to both sides of the diversion pipe 901, and multiple spray heads 903 are fixedly connected to the outer walls of the two sets of spray pipes 902. It should be noted that the two sets of spray pipes 902 spray in opposite directions. One set of spray pipes 902 is close to the hydraulic power roller 8 and is used to flush the surface of the hydraulic power roller 8. This can clean up the adhering subgrade material in time, prevent the subgrade material from accumulating and affecting the compaction effect, and protect the surface of the hydraulic power roller 8, thus extending its service life. The other set of spray pipes 902 is used to spray dry and loose subgrade material. By increasing the moisture content of the subgrade material, it can enhance the bonding force between the subgrade material particles, reduce dust generation, improve the density of subsequent compaction, and ensure the overall stability of the subgrade. It should also be noted that a water storage tank and a water pump are fixedly installed inside the power control system 2, and the top end of the diversion pipe 901 is fixedly connected to the water pump through the connecting water pipe 904. The outer wall of the diversion pipe 901 is fixedly fitted with a positioning frame 912, and the positioning frame 912 is fixedly installed on the top surface of the movable frame 7. A movable shaft 905 is slidably installed in the inner cavity of the spray head 903. A baffle plate 906 is fixedly sleeved on the outer wall of the movable shaft 905 to adjust the flow state inside the spray head 903. Four sets of expansion plates 907 are rotatably connected to the outer wall of the spray head 903 through pins to expand the spray range of the spray head 903. It should be noted that the baffle plate 906 is made of silicone, and its diameter is equal to the inner diameter of the spray head 903. It can adjust the water flow and prevent dust from entering the spray head 903 when not in use. At the same time, the moving shaft 905 and each set of expansion plates 907 are rotatably connected to the transmission rod 908 through the pin. When water is flowing, the water flow pushes the baffle plate 906 to drive the moving shaft 905 to move downward. The transmission rod 908 pushes the expansion plate 907 to expand outward, guiding the water flow to scatter outward and flexibly adjusting the spray coverage area (specifically, the expansion plate 907 is made of rubber, which can produce a certain degree of elastic deformation when flipped outward, avoiding dead spots and jamming, and can produce a smooth spray interface). It should also be noted that a fixing bracket 909 is fixedly installed on the inner wall of the spray head 903, and a fixing pipe 910 is fixedly connected to one side of the fixing bracket 909. The top end of the moving shaft 905 slides on the fixing pipe 910, and a return spring 911 is fixedly installed between the two. When the water flow pushes the moving shaft 905 down, the return spring 911 is stretched. After the water stops, the elastic force of the return spring 911 pulls the moving shaft 905 back to its original position, so that the baffle plate 906 closes the spray head 903 and the expansion plate 907 retracts, thereby realizing the automatic reset of the spray assembly 9 and ensuring the sealing and structural stability.

[0021] Please see Figure 3 , Figure 5 The cleaning component 10 includes a scraper 101, which is fixedly installed on the inner wall of the movable frame 7. A rotating shaft 102 is rotatably installed in the inner cavity of the scraper 101, and multiple sets of claws 103 are fixedly sleeved on the outer wall of the rotating shaft 102. It should be noted that one side of the scraper 101 is attached to the outer surface of the hydraulic power roller 8. The scraper 101 can directly scrape off the roadbed material adhering to the outer wall of the hydraulic power roller 8. The outer wall of the moving frame 7 is fixedly installed with a motor 104, and the output end of the motor 104 is fixedly connected to the rotating shaft 102. The rotating shaft 102 can drive the claw 103 to rotate, which helps to clean the residual material on the scraper 101 and improve the cleaning effect (specifically, as the residual material on the scraper 101 increases, the residual material on the scraper 101 will be pushed towards the claw 103. At this time, when the claw 103 rotates, it can clean the residual material hanging off the scraper 101). A ramp 105 is fixedly connected to the side of the scraper 101 away from the hydraulic power roller 8, and a collection box 106 is fixedly connected to one side of the ramp 105 for collecting the adhesive material after scraping. It should be noted that both the scraper 101 and the ramp 105 have rotating grooves inside for providing rotation for the claw 103, and the claw 103 is located in the rotating groove. The ramp 105 has a certain tilt angle to facilitate material sliding. Both sides of the ramp 105 and the collection box 106 are fixedly connected to the inner wall of the moving frame 7 to ensure structural stability and prevent parts from shifting during the cleaning process. It should also be noted that the bottom of the collection box 106 is hinged to an opening and closing plate 107. The opening and closing plate 107 and the side wall of the collection box 106 are respectively fixedly connected to a locking block 108 and a buckle 109, and the two can lock the collection box 106 to ensure that the material does not leak during the collection process. After the material in the collection box 106 is full, the opening and closing plate 107 can be opened by releasing the locking block 108 and the buckle 109 to quickly clean up the waste. The operation is convenient.

[0022] Please see Figure 1 , Figure 2Both sides of the bracket 3 are rotatably mounted with electric push rods 11 for providing power to adjust the angle of the scraping blade 6 via pins, and the bottom end of the electric push rod 11 is ball-hinged with the movable frame 5. It should be noted that the internal cavity of the power control system 2 is fixedly equipped with a hydraulic pump, hydraulic valves and speed regulating structure. By adjusting the flow and pressure of the hydraulic oil, the rolling pressure and rotation speed of the hydraulic power roller 8 are precisely controlled. According to the characteristics of the roadbed material and the compaction requirements, the appropriate pressure can be precisely output to ensure that the compaction degree meets the standard. At the same time, the rotation speed is adjusted to match the construction progress, so as to achieve a balance between compaction effect and work efficiency and ensure the stability of the roadbed (the specific hydraulic oil circuit connection relationship is the existing technology and will not be described in detail here).

[0023] The working principle of this utility model is as follows: When this utility model is in use, the power control system 2 first provides power to the whole machine, and the operator controls each component through the cockpit 1, which in turn drives the whole machine to move in conjunction with the drive structure 4. When the equipment moves, the leveling blade 6 trims the roadbed surface to ensure initial flatness. The electric push rod 11 can push the movable frame 5 to rotate, thereby adjusting the tilt angle of the leveling blade 6 to adapt to different roadbed flatness requirements. At the same time, the sensors on the inner wall of the leveling blade 6 and the hydraulic power roller 8 collect roadbed flatness and compaction data in real time, providing a basis for subsequent compaction parameter adjustment. As the equipment continues to move, the hydraulic power roller 8 compacts the repaired roadbed. The hydraulic pump, hydraulic valve and speed control structure control the rolling pressure and speed of the hydraulic power roller 8. At the same time, the spraying component 9 is started. The water pump in the power control system 2 delivers water from the water storage tank to the diversion pipe 901 through the connecting water pipe 904, and then to two sets of spray pipes 902. One set washes the surface of the hydraulic power roller 8 to help clean the adhering materials, and the other set sprays to dry the roadbed, increase the moisture content of the materials to reduce dust, enhance the particle adhesion and improve the compaction effect. Furthermore, when water flows through the inside of the spray head 903, the water flow pushes the baffle plate 906 and the moving shaft 905 to move, and drives the expansion plate 907 to expand outward via the transmission rod 908, guiding the water flow to scatter outward. After the water stops, the reset spring 911 pulls the moving shaft 905 to reset, so that the baffle plate 906 closes the spray head 903 and the expansion plate 907 is retracted, realizing the automatic diffusion range, and resetting and sealing after the water stops. At the same time, the cleaning component 10 works synchronously. The scraper 101 is in contact with the surface of the hydraulic power roller 8. When the hydraulic power roller 8 rotates, it directly scrapes off the roadbed material adhering to its outer wall. At the same time, the motor 104 drives the rotating shaft 102 and the claw 103 to rotate, which helps to clean the residual material on the scraper 101. The scraped waste slides down the inclined ramp 105 into the collection box 106. The collection box 106 is sealed by the latch 108 and the buckle 109. When it is full, the buckle 109 can be released to open the opening and closing plate 107 to clean the waste, ensuring the continuity of roller cleaning and construction.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
