Description
Technical Field
[0001] This application relates to the technical field of highway construction devices, and in particular to a subgrade leveling device. Background Art
[0002] The highway subgrade is the foundation of the road surface. It bears the self-weight of the soil and rock itself, the weight of the road surface, and the traffic load transmitted from the road surface. It is the load-bearing main body of the highway; the construction of the subgrade destroys the natural state of the soil mass, making the structure loose, and the particles need to be recombined. In order to make the subgrade have sufficient strength and stability, compaction must be carried out to improve its density; therefore, the compaction work of the subgrade is an important process in the subgrade construction process and is also one of the fundamental technical measures to improve the strength and stability of the subgrade.
[0003] In the prior art, highway compaction equipment generally includes a vehicle body, a support frame, and a compaction roller. A support rod is fixedly arranged inside the support frame, and the compaction roller is rotatably connected to the peripheral side wall of the support rod. The driver drives the vehicle body forward, so as to be able to push the compaction roller to roll on the road surface, and then be able to compact the road surface.
[0004] Regarding the above related technology, the inventor believes that after the compaction roller is used for a long time, sticky material particles adhere to the roller surface. The roller surface is in contact with the material particles for a long time, which is likely to cause abrasion, pitting, etc. on the roller surface of the roller press, thereby increasing the vibration intensity of the compaction roller, and then possibly generating destructive force on the compaction equipment. Summary of the Utility Model
[0005] In order to reduce the wear degree of the roller surface of the compaction roller, thereby being able to reduce the vibration intensity of the compaction roller, and further reduce the possibility of damage to the compaction equipment, this application provides a subgrade leveling device.
[0006] A subgrade leveling device provided by this application adopts the following technical solution:
[0007] A subgrade leveling device includes a support frame, a support rod, and a compaction roller. A support plate is fixedly arranged on the support frame. A storage groove is formed inside the support plate. A cleaning brush is detachably connected inside the storage groove. The cleaning brush includes a brush plate and bristles. The bristles are slidably connected to the roller surface of the compaction roller. The brush plate abuts against the inner wall of the storage groove. A support cover is movably connected to the support plate. The inner wall of the support cover can abut against the brush plate; A collection hopper for collecting the cleaned materials is rotatably arranged on the support frame.
[0008] By adopting the above technical solution, before the driver drives the vehicle body, the driver opens the support cover, then installs the cleaning brush into the storage groove, and then closes the support cover to fix the cleaning brush; when the driver drives the vehicle body, the compaction roller rotates. During the rotation of the compaction roller, the bristles of the cleaning brush abut against the roller surface of the compaction roller, so that the material particles adhering to the roller surface of the compaction roller can be swept into the collection hopper, thereby reducing the possibility of the material particles wearing the compaction roller surface, further reducing the vibration intensity of the compaction roller, and thus reducing the possibility of damage to the compaction equipment.
[0009] Preferably, a placement groove is formed in the inner wall of the storage groove, and a first spring and a plug block are arranged in the placement groove. Two ends of the first spring are respectively fixedly arranged on the inner wall of the placement groove and the plug block; the plug block is slidably connected to the inner wall of the placement groove, and a plug slot for the plug block to be inserted is formed on the brush plate.
[0010] By adopting the above technical solution, during the process of the driver placing the cleaning brush in the storage groove, the brush plate can abut against the plug block and push the plug block to compress the first spring and move into the placement groove. When the bottom end of the brush plate abuts against the inner wall of the storage groove, the plug block is aligned with the plug slot on the brush plate, and the plug block is inserted into the plug slot under the elastic force of the first spring, thereby reducing the possibility of the cleaning brush detaching from the support plate.
[0011] Preferably, connecting blocks are respectively fixedly arranged at opposite ends of the support plate, a connecting rod is fixedly arranged on the support cover, and two ends of the connecting rod are respectively rotatably connected to opposite side walls of the two connecting blocks. A limiting component for limiting the connecting rod is arranged on the support plate.
[0012] By adopting the above technical solution, after the driver installs the cleaning brush, the driver rotates the support cover towards the support plate. The rotation of the support cover drives the connecting rod to rotate. The inner wall of the support cover abuts against the brush plate of the cleaning brush. Under the action of the limiting component, the driver makes the support cover in a closed state, thereby strengthening the fixation of the position of the cleaning brush and further reducing the possibility of the cleaning brush moving.
[0013] Preferably, a fixing block is fixedly arranged on the support plate, a fixing groove is formed in the fixing block, a limiting groove is formed on the support cover, and the limiting component includes a gear, a plug block and a second spring; the gear is arranged in the limiting groove, and the gear is fixedly sleeved on the connecting rod; the plug block and the second spring are arranged in the fixing groove, a slope is arranged on the plug block, the plug block is slidably connected to the inner wall of the fixing groove, and the plug block can be inserted into the tooth groove of the gear; two ends of the second spring are fixedly arranged on the plug block and the inner wall of the fixing groove.
[0014] By adopting the above technical solution, when the connecting rod rotates following the support cover, the gear rotates following the connecting rod. At this time, the inner wall of the tooth groove of the gear abuts against the side wall of the insertion block, and the insertion block is pushed by the inclined surface of the insertion block to compress the second spring and move into the fixing groove. After the support cover is closed, the connecting rod and the gear stop rotating, and the insertion block abuts against the tooth groove of the gear, thereby being able to reduce the possibility of the support cover reversing.
[0015] Preferably, a torsion spring is sleeved on the connecting rod, and the torsion arms at both ends of the torsion spring are respectively fixedly arranged on the opposite side walls of the connecting block and the support cover; one end of the insertion block is fixedly provided with a pull rod, and the other end of the pull rod passes through and is slidably connected to the inner wall of the fixing groove.
[0016] By adopting the above technical solution, when the cleaning brush is damaged after long-term use and needs to be replaced, first, the staff pulls the pull rod to move away from the fixed block. The movement of the pull rod can drive the insertion block to compress the second spring and move away from the gear. When the insertion block is away from the gear, the connecting rod rotates under the elastic force of the torsion spring, and the rotation of the connecting rod can drive the support cover to rotate and open, so that the driver can replace the cleaning brush.
[0017] Preferably, connecting plates are fixedly arranged on the opposite sides at one end of the support frame. A collecting hopper is rotatably arranged in the support frame. A rotating rod is fixedly arranged on the collecting hopper, and the two ends of the rotating rod are respectively rotatably connected to the opposite side walls of the two connecting plates. A first motor is fixedly installed on one of the connecting plates, and one end of the rotating rod is fixedly arranged on the rotating shaft of the first motor.
[0018] By adopting the above technical solution, when there are more material particles collected in the collecting hopper, the driver starts the first motor. The rotation of the rotating shaft of the first motor drives the rotating rod to rotate, and the rotation of the rotating rod can drive the collecting hopper to rotate, so that the hopper opening of the collecting hopper rotates downward, and thus the physical particles in the collecting hopper can be cleared out of the collecting hopper.
[0019] Preferably, a support frame is fixedly arranged on the support rod. A scraping plate is slidably arranged on the support frame. The scraping plate can abut against the compaction roller, and a driving component capable of driving the scraping plate to move is arranged on the support frame.
[0020] By adopting the above technical solution, when there is material on the surface of the compaction roller that the cleaning brush fails to clean, the driver uses the driving component to make the scraping plate approach and abut against the roller surface of the compaction roller, so that the stubborn material on the roller surface can be shoveled off. After the stubborn material on the roller surface is cleaned, the driver uses the driving component again to make the scraping plate away from the roller surface, thereby being able to reduce the possibility of damage to the roller surface of the compaction roller due to long-term friction of the scraping plate.
[0021] Preferably, first sliding grooves and second sliding grooves are respectively formed in opposite side walls of the support frame; the driving assembly includes a guide rod, a lead screw, and a second motor; both ends of the guide rod are fixedly arranged on opposite inner walls of the first sliding groove, and both ends of the lead screw are rotatably connected to opposite inner walls of the second sliding groove; the second motor is fixedly installed on the support frame, and one end of the lead screw is fixedly arranged on the rotating shaft of the second motor; the scraping plate is slidably connected to the guide rod, and the scraping plate is in threaded cooperation with the lead screw.
[0022] By adopting the above technical solution, when the driver is ready to drive the scraping plate close to the compaction roller, the driver turns on the second motor. The rotation of the rotating shaft of the second motor drives the lead screw to rotate. Under the guiding action of the guide rod, the scraping plate moves along the axial line direction of the lead screw, so as to drive the scraping plate close to or away from the compaction roller.
[0023] In summary, the present application includes at least one of the following beneficial technical effects:
[0024] 1. Before the driver drives the vehicle body, the driver opens the support cover, then installs the cleaning brush into the storage groove, and then closes the support cover to fix the cleaning brush; when the driver drives the vehicle body to travel, the compaction roller rotates. During the rotation of the compaction roller, the bristles of the cleaning brush abut against the roller surface of the compaction roller, so as to be able to sweep the sticky material particles on the roller surface of the compaction roller into the collection hopper, thereby reducing the possibility of the material particles wearing the roller surface of the compaction roller, further reducing the vibration intensity of the compaction roller, and thus reducing the possibility of damage to the compaction equipment;
[0025] 2. When the connecting rod rotates following the support cover, the gear rotates following the connecting rod. At this time, the inner wall of the tooth groove of the gear abuts against the side wall of the plug, and the plug is pushed by the inclined surface of the plug to compress the second spring and move into the fixing groove. After the support cover is closed, the connecting rod and the gear stop rotating, and the plug abuts in the tooth groove of the gear, so as to reduce the possibility of reverse rotation of the support cover;
[0026] 3.

Detailed implementation manners
[0035] The following further elaborates on the present application in conjunction with the attached Figures 1-6 drawings.
[0036] An embodiment of the present application discloses a roadbed leveling device. As Figure 1 and Figure 2 shown, and in conjunction with Figure 3, including a support frame 1, support rods 2 and a compaction roller 3. A support plate 4 is fixedly arranged inside the support frame 1. The support plate 4 is in the shape of a cuboid, and both ends of the support plate 4 are fixedly welded to the opposite side walls at the right end of the support frame 1. A storage groove 5 is formed inside the support plate 4. The storage groove 5 extends in the vertical direction, and the length of the storage groove 5 is the same as the length of the support plate 4. A cleaning brush is detachably connected inside the storage groove 5. The cleaning brush includes a brush plate 7 and bristles 8. The brush plate 7 is in the shape of a cuboid, and the bottom end of the brush plate 7 is inserted into the storage groove 5. A through groove 38 is formed in the inner wall of the storage groove 5 close to the compaction roller 3. The through groove 38 extends horizontally along the width direction of the support plate 4. The bristles 8 pass through the through groove 38 and are slidably connected to the roller surface of the compaction roller 3; The top end of the support plate 4 is movably connected with a support cover 9. The cross section of the support cover 9 is in the shape of an L. The inner side wall of the support cover 9 can abut against the left side wall of the brush plate 7, and the inner wall of the top end of the support cover 9 can abut against the top side wall of the brush plate 7; Connection blocks 15 are fixedly welded to the bottom ends of the opposite side walls of the support frame 1. The connection blocks 15 are in the shape of cuboids, and a collection hopper 10 is rotatably arranged between the two connection blocks 15.
[0037] As Figure 2 and Figure 4 shown, a placement groove 11 is formed in the inner wall of the left end of the bottom of the storage groove 5. The placement groove 11 extends horizontally. An insertion block 13 and a plurality of first springs 12 are arranged inside the placement groove 11. The first springs 12 are arranged horizontally. The left and right ends of the first springs 12 are respectively fixedly welded to the left inner wall of the placement groove 11 and the left side wall of the insertion block 13; The insertion block 13 is composed of a cuboid block and a semi-cylinder. The insertion block 13 is slidably connected to the inner wall of the placement groove 11 in the horizontal direction. An insertion slot 14 for inserting the insertion block 13 is formed in the brush plate 7 in the horizontal direction.
[0038] As Figure 1 and Figure 2 shown, when the driver drives the vehicle body to travel, the compaction roller 3 rotates. During the rotation of the compaction roller 3, the roller surface of the compaction roller 3 is rotatably connected to the bristles 8 of the cleaning brush 6, so that the bristles 8 can sweep away the material particles adhering to the roller surface of the compaction roller 3. The swept-away material particles can fall into the collection hopper 10 below the cleaning brush 6, thereby reducing the possibility of wear of the surface of the compaction roller 3 due to material particles, further reducing the vibration intensity of the compaction roller 3, and thus reducing the possibility of damage to the compaction equipment;
[0039] As Figure 2 and Figure 3 shown, and in combination with Figure 4, when the bristles 8 are damaged due to long-term use, first, the driver opens the support cover 9. Then, the driver pulls the cleaning brush 6 upward. During the process of the cleaning brush 6 being forced to move upward, the inner wall of the insertion slot 14 on the brush plate 7 pushes the insertion block 13 to compress the first spring 12 and move into the placement slot 11. When the insertion block 13 is away from the insertion slot 14, the driver can take away the cleaning brush 6. After that, the driver inserts the replaced cleaning brush 6 into the storage slot 5. During the process of the brush plate 7 being inserted into the storage slot 5, the brush plate 7 abuts against the insertion block 13 and pushes the insertion block 13 to compress the first spring 12 and move into the placement slot 11. When the insertion slot 14 is aligned with the insertion block 13, the insertion block 13 is inserted into the insertion slot 14 under the push of the first spring 12, thereby reducing the possibility of the brush plate 7 moving. Finally, the driver closes the support cover 9 to fix the position of the cleaning brush 6 again.
[0040] As Figure 3 and as Figure 5 shown, connection blocks 15 are respectively fixedly welded to the left and right ends on the top end of the support plate 4. A connecting rod 16 is arranged between the two connection blocks 15. The connecting rod 16 is cylindrical, and its axis is arranged horizontally. The two ends of the connecting rod 16 are respectively rotatably connected to the opposite side walls of the two connection blocks 15. A rotating block 39 is welded to the side wall of the support cover 9. The rotating block 39 is integrally formed with the support cover 9. The rotating block 39 is fixedly sleeved on the peripheral side wall of the connecting rod 16. Torsion springs 24 are sleeved on both ends of the connecting rod 16. The torsion arms at both ends of the torsion spring 24 are respectively fixedly welded to the opposite side walls of the connection block 15 and the rotating block 39. A limiting slot is provided on the rotating block 39, and a limiting component 17 for limiting the connecting rod 16 is arranged in the limiting slot.
[0041] As Figure 5 shown, a fixing block 18 is fixedly welded to the side wall of the top end of the support plate 4. The fixing block 18 is rectangular parallelepiped-shaped. The fixing block 18 is provided with a fixing slot 19 along the horizontal direction, and the fixing slot 19 extends along the horizontal direction. The limiting component 17 includes a gear 21, an insertion block 22, and a second spring 23. The gear 21 is arranged in the limiting slot 20. The axis of the gear 21 is arranged horizontally, and the gear 21 is fixedly sleeved on the connecting rod 16. The insertion block 22 and the second spring 23 are arranged in the fixing slot 19. The insertion block 22 is rectangular parallelepiped-shaped. The second spring 23 is arranged in the horizontal direction. One end of the insertion block 22 close to the gear 21 is provided with an inclined surface. The insertion block 22 is provided with an inclined surface. The insertion block 22 is slidably connected to the inner wall of the fixing slot 19 along the horizontal direction. The left end of the insertion block 22 can be inserted into the tooth slot of the gear 21. The left and right ends of the second spring 23 are fixedly welded to the right end of the insertion block 22 and the inner wall of the right end of the fixing slot 19. A pull rod 25 is fixedly welded to the right end of the insertion block 22. The pull rod 25 is cylindrical, and its axis is arranged horizontally. The right end of the pull rod 25 passes through and is slidably connected to the inner wall of the fixing slot 19 along the horizontal direction. A pull block 26 is fixedly welded to the right end of the pull rod 25.
[0042] As Figure 3 and Figure 5 shown, when the driver needs to replace the long-term used cleaning brush 6, first, the driver pulls the pulling block 26 to move away from the fixed block 18. The pulling block 26 drives the pull rod 25 to move together. The movement of the pull rod 25 drives the inserting block 22 to compress the second spring 23 and move away from the gear 21. When the inserting block 22 moves away from the gear 21, the connecting rod 16 rotates under the elastic force of the torsion spring 24. The rotation of the rotating rod 28 can drive the support cover 9 to rotate, so that the support cover 9 can be automatically opened, thereby reducing the driver's working intensity. After the cleaning brush 6 is replaced when the support cover 9 is opened, the driver rotates the support cover 9 downward. The rotation of the support cover 9 drives the connecting rod 16 and the gear 21 to rotate, and the torsion arm of the torsion spring 24 moves accordingly. When the gear 21 rotates, the inclined surface on the inserting block 22 pushes the inserting block 22 to compress the second spring 23 and move. When the support cover 9 is closed, the inserting block 22 is inserted into the groove of the gear 21, so that the possibility of the gear 21 reversing can be reduced, and thus the fixing property of the support cover 9 can be enhanced.
[0043] As Figure 6 shown, a rotating rod 28 is arranged between the two connecting plates 27. The rotating rod 28 is cylindrical, and its axis is arranged horizontally. The two ends of the rotating rod 28 are respectively rotatably connected to the opposite side walls of the two connecting plates 27. The two ends of the rotating rod 28 are fixedly penetrated through the opposite side walls of the collector. A first motor 29 is fixedly installed on the left connecting plate 27 through bolts. The left end of the rotating rod 28 is fixedly connected to the rotating shaft of the first motor 29 through a coupling. When the material particles in the collecting hopper 10 are full, after the driver drives the vehicle body to a suitable position, the driver starts the first motor 29. The rotating shaft of the first motor 29 can drive the rotating rod 28 to rotate. The rotation of the rotating rod 28 can drive the collecting hopper 10 to rotate until the hopper opening faces downward, so that the material particles in the collecting hopper 10 can be poured out. After that, the driver drives the rotating rod 28 through the first motor 29 again to drive the collecting hopper 10 to rotate until the hopper opening faces upward.
[0044] As Figure 1As shown in Fig. 2, support frames 30 are fixedly welded to both ends of the support rod 2. A scraper 31 is slidably arranged on the support frames 30. The scraper 31 is in the shape of a cuboid, and the bottom side wall of the scraper 31 can abut against the compaction roller 3. A driving assembly 32 capable of driving the scraper 31 to move is provided on the support frames 30; first sliding grooves 33 and second sliding grooves 34 are respectively formed in the opposite side walls of the support frames 30 along the height extension direction of the support frames 30; the driving assembly 32 includes a guide rod 35, a lead screw 36 and a second motor 37; the guide rod 35 is in the shape of a cylinder, and the upper and lower ends of the guide rod 35 are respectively fixedly welded to the upper and lower opposite inner walls of the first sliding groove 33; the upper and lower ends of the lead screw 36 are respectively rotatably connected to the upper and lower opposite inner walls of the second sliding groove 34; the second motor 37 is fixedly installed on the top side wall of the support frames 30 by bolts. The top end of the lead screw 36 penetrates through the inner wall of the second sliding groove 34 and is fixedly connected to the rotating shaft of the second motor 37 through a coupling; one end of the scraper 31 is slidably connected to the guide rod 35, and the other end of the scraper 31 is in threaded fit with the lead screw 36.
[0045] As Figure 1 As shown in Fig. 2, when there is material on the surface of the compaction roller 3 that cannot be cleaned by the cleaning brush 6, at this time, the driver turns on the second motor 37. The rotation of the rotating shaft of the second motor 37 drives the lead screw 36 to rotate. Under the guiding action of the guide rod 35, the scraper 31 moves along the axis direction of the lead screw 36, so as to drive the scraper 31 to approach the compaction roller 3 and be slidably connected to the compaction roller 3, and then the stubborn material on the roller surface can be shoveled off. After the stubborn material on the roller surface is cleaned, the driver drives the scraper 31 to move away from the roller surface again through the second motor 37, so as to reduce the possibility of damage to the roller surface of the compaction roller 3 due to long-term friction with the scraper 31.
[0046] The implementation principle of the embodiment of the present application is as follows: when the driver drives the vehicle body to drive the compaction roller 3 to compact the road surface, the bristles 8 of the cleaning brush 6 are slidably connected to the roller surface of the compaction roller 3, and can sweep the sticky material particles on the roller surface into the collection hopper 10. When there are material stains on the roller surface that cannot be swept by the cleaning brush 6, the driver turns on the second motor 37, and drives the scraper 31 to approach the compaction roller 3 and be slidably connected to the compaction roller 3 through the second motor 37, so as to shovel off the stubborn material stains. After that, the second motor 37 drives the scraper 31 away from the compaction roller 3, so as to reduce the possibility of damage to the roller surface of the compaction roller 3 due to long-term friction with the scraper 31; when the bristles 8 are damaged after long-term use and need to be replaced with a new cleaning brush 6; at this time, the driver releases the limiting effect on the support cover 9, and the support cover 9 opens under the elastic force of the torsion spring 24. Then, the driver replaces the new cleaning brush 6. Finally, the driver closes the support cover 9 and limits the support cover 9 through the limiting assembly 17.
[0047] The above are all preferred embodiments of this application, and the protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
