Description

Technical Field

[0001] The present invention belongs to the technical field of road construction, and particularly relates to a roadbed and pavement compaction device for highway construction and its usage method. Background Art

[0002] A highway is built according to national technical standards to connect cities, villages, and industrial and mining bases. A road mainly for vehicles to travel and with certain technical standards and facilities is called a highway. When building a highway, the road surface needs to be compacted to ensure the safety and service life of the road. Currently, the existing roadbed and pavement compaction usually uses a heavy roller. A heavy roller is equipped with a gravity wheel with a relatively large weight. During the compaction process, the gravity wheel is pushed to roll on the road surface to be compacted, and the roadbed and pavement are compacted by gravity. In order to increase the weight of the roller and ensure the flatness of the roadbed, the wheels of existing rollers are mostly made of metal. The texture of metal is hard, which can easily crush the stones on the roadbed and reduce the wear of the wheels, prolonging the service life. However, because the wheels of the roller are relatively hard, it is easy to damage the road surface when the roller travels on the road surface. When the roller needs to be transferred to another site, a special vehicle is required to transport it, which is cumbersome to operate and increases the usage cost of the roller, and is not convenient for the roller to make short-distance transfers. Summary of the Invention

The side surfaces of the two guide rings away from each other are inclined surfaces, and load-bearing rings are fixedly arranged on the side surfaces of the two guide rings away from each other. Limiting rings are fixedly arranged on the side surfaces of the two load-bearing rings away from each other. The outer diameter dimension of the load-bearing ring is smaller than the outer diameter dimension of the rolling wheel. The outer diameter dimension of the limiting ring is larger than the inner diameter dimension of the load-bearing ring, and the outer diameter dimension of the limiting ring is equal to or smaller than the outer diameter dimension of the rolling wheel.

[0007] As a preferred solution of the present invention, two positioning rings are symmetrically arranged on the auxiliary wheel, and the two positioning rings are fixedly sleeved on the auxiliary wheel. The buffer ring is located between the two positioning rings.

[0008] As a preferred solution of the present invention, a limiting plate is fixedly arranged on the transverse vertical plate. An extrusion rotating rod is also rotatably arranged on the transverse vertical plate. An I-shaped rotating plate is fixedly arranged on the extrusion rotating rod.

An installation seat is fixedly arranged on one side surface of the protective cover away from the extrusion wheel.

[0012] As a preferred embodiment of the present invention, the mud scraping plate is located on one side of the rolling wheel close to the installation seat, and the mud scraping plate is located between the rolling wheel and the protective cover.

[0013] A method for using a road construction subgrade and pavement compaction device includes the following steps: S1: Fix the installation seat on an engineering vehicle, which can integrate the transverse vertical plate and the rolling wheel with the engineering vehicle, and can electrically connect the push-pull electromagnet and the electric push rod with the engineering vehicle, facilitating the control of the opening and closing of the push-pull electromagnet and the electric push rod. The rolling wheel can be driven by the engineering vehicle to move and compact the subgrade. S2: Rotate the mud scraping plate to separate it from the rolling wheel. By rotating the east mud scraping plate through the electric push rod, the working state of the mud scraping plate can be controlled, and then the working state of the rolling wheel can be conveniently controlled. S3: Use the electromagnet to push the clamping long plate to move, so that the clamping long plate extrudes a section of the buffer ring from the bearing ring onto the rolling wheel. When the rolling wheel rotates, it can compact the buffer ring. S4: Rotate the I-shaped rotating plate to drive the extrusion wheel to rotate, and loosen the buffer ring, so that the buffer ring has a tensioning and relaxing effect, which can avoid breaking the buffer ring. S5: After the buffer ring completely covers the rolling wheel, rotate the I-shaped rotating plate to drive the extrusion wheel to reset. The extrusion wheel presses the buffer ring to make the buffer ring tight. When the rolling wheel rotates more than one circle, the buffer ring can gradually be sleeved on the rolling wheel.

[0014] Compared with the prior art, the beneficial effects of the present invention are: This road construction subgrade and pavement compaction device is provided with a buffer mechanism. By using the push-pull electromagnet in the buffer mechanism, the push-pull electromagnet can push the connecting plate to move, so that the connecting plate can drive the moving plate to move, and then the connecting rod can drive the clamping short plate and the clamping long plate to move, so that the clamping long plate can extrude the buffer ring, and a section of the buffer ring can move onto the rolling wheel. As the rolling wheel rotates, the buffer ring can be sleeved on the rolling wheel, and then the buffer ring can play a buffering role, avoiding the rolling wheel from contacting the road surface, thereby avoiding damage to the road surface by the rolling wheel and facilitating the short-distance transfer of the road roller. This road construction subgrade and pavement compaction device is provided with a mud scraping mechanism. By using the mud scraping plate in the mud scraping mechanism, the rolling wheel can rotate relative to the mud scraping plate when it rotates. As a result, the mud blocks adhering to the rolling wheel can come into contact with the mud scraping plate, enabling the mud scraping plate to clean the mud blocks on the rolling wheel, ensuring the cleanliness of the rolling wheel, avoiding potholes in the subgrade after compaction, and improving the compaction effect of the subgrade. This road construction subgrade and pavement compaction device is provided with a torsion spring. The torsion spring can push the I-shaped rotating plate to rotate, and then the I-shaped rotating plate can drive the extrusion wheel to rotate. Thus, the extrusion wheel can extrude the buffer ring while ensuring its normal rotation, making the buffer ring always in a taut state, preventing the buffer ring from loosening and contacting the ground, and improving safety.

Detailed Embodiments

[0017] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0018] For the embodiments, please refer to Figures 1-8 , the present invention provides a compaction device for the roadbed and pavement of highway construction, which includes a rolling wheel 1, a mud scraping mechanism 2, two buffer mechanisms 3 and two lateral vertical plates 4. The two lateral vertical plates 4 are symmetrically arranged. The rolling wheel 1 is rotatably arranged on the two lateral vertical plates 4. The mud scraping mechanism 2 is arranged on the two lateral vertical plates 4. The two buffer mechanisms 3 are respectively arranged on the two lateral vertical plates 4. The mud scraping mechanism 2 and the two buffer mechanisms 3 are both connected to the rolling wheel 1; In this embodiment, refer to Figures 1-8As shown in the figure, the buffer mechanism 3 includes a fixed rod 301, an auxiliary wheel 302, a U-shaped seat 303, a moving plate 304, a push-pull electromagnet 305, a buffer ring 306, a connecting plate 307, a clamping short plate 308 and a clamping long plate 309. The fixed rod 301 is fixedly arranged on the transverse vertical plate 4. The auxiliary wheel 302 is rotatably sleeved on the fixed rod 301 through a bearing. The buffer ring 306 is slidably sleeved on the rolling wheel 1 and the auxiliary wheel 302. Both the U-shaped seat 303 and the push-pull electromagnet 305 are fixedly arranged on the vertical plate, and the push-pull electromagnet 305 is located inside the U-shaped seat 303. The connecting plate 307 is slidably arranged on the U-shaped seat 303. The end of the output shaft of the push-pull electromagnet 305 is fixedly connected to the connecting plate 307. A strip-shaped hole 3010 is formed in the U-shaped seat 303. One end of the connecting plate 307 away from the push-pull electromagnet 305 slidably penetrates through the strip-shaped hole 3010 and is fixedly connected to the moving plate 304. The moving plate 304 is slidably connected to the U-shaped seat 303. Both the clamping short plate 308 and the clamping long plate 309 are fixedly arranged on the side surface of the moving plate 304 away from the connecting plate 307. The buffer ring 306 is located between the clamping short plate 308 and the clamping long plate 309. The buffer ring 306 can be separated from the rolling wheel 1. Starting the push-pull electromagnet 305 can push the connecting plate 307 to move, so that the connecting plate 307 can drive the moving plate 304 to move, and further the moving plate 304 can drive the clamping long plate 309 to move, so that the clamping long plate 309 can squeeze one part of the buffer ring 306, so that one part of the buffer ring 306 can be squeezed onto the rolling wheel 1. As the rolling wheel 1 rotates, a section of the buffer ring 306 can be rolled under the rolling wheel 1. When the rolling wheel 1 rotates one circle, the buffer ring 306 can be completely squeezed onto the rolling wheel 1, so that the buffer ring 306 can isolate the rolling wheel 1 from the road surface, avoiding the contact between the rolling wheel 1 and the road surface, and further avoiding the damage of the road surface under pressure. When controlling the contraction of the push-pull electromagnet 305, the moving plate 304 can be pulled back to its original position, and further the clamping short plate 308 can push a section of the buffer ring 306 away from the rolling roller, facilitating the removal of the buffer ring 306 from the rolling wheel 1 to ensure the normal use of the rolling wheel 1; Among them, two guide rings 5 are fixedly arranged on the rolling wheel 1, and the two guide rings 5 are symmetrically arranged. The side surfaces of the two guide rings 5 away from each other are inclined surfaces, and bearing rings 6 are fixedly arranged on the side surfaces of the two guide rings 5 away from each other. Limiting rings 7 are fixedly arranged on the side surfaces of the two bearing rings 6 away from each other. The outer diameter dimension of the bearing ring 6 is smaller than the outer diameter dimension of the rolling wheel 1. The outer diameter dimension of the limiting ring 7 is larger than the inner diameter dimension of the bearing ring 6, and the outer diameter dimension of the limiting ring 7 is equal to or smaller than the outer diameter dimension of the rolling wheel 1. The buffer ring 306 can be sleeved on the bearing ring 6, so that the outer diameter dimension of the buffer ring 306 sleeved on the bearing ring 6 is still smaller than the outer diameter dimension of the rolling wheel 1, which can avoid affecting the work of the rolling wheel 1. When there is no need to transfer the site, the buffer ring 306 is always sleeved on the bearing ring 6, which can avoid the buffer ring 306 from being too loose, and further avoid the buffer ring 306 from contacting the ground, improving the safety. When the buffer ring 306 is located on the bearing ring 6, the limiting ring 7 can limit the buffer ring 306 to prevent the buffer ring 306 from falling off the bearing ring 6, improving the safety. When the clamping long plate 309 squeezes the buffer ring 306, the buffer ring 306 can move onto the rolling wheel 1 along the inclined surface on the guide ring 5, which is convenient for the movement of the buffer ring 306 and improves the convenience; Among them, two positioning rings 8 are symmetrically arranged on the auxiliary wheel 302, and the two positioning rings 8 are fixedly sleeved on the auxiliary wheel 302. The buffer ring 306 is located between the two positioning rings 8. The auxiliary wheel 302 can stretch and fix a section of the buffer ring 306 away from the clamping long plate 309, which is convenient for the clamping long plate 309 to push the buffer ring 306 to move onto the rolling wheel 1. The positioning ring 8 can limit the buffer ring 306 to prevent the buffer ring 306 from detaching from the auxiliary wheel 302, improving the safety; In this embodiment, refer to Figures 7-8, a limiting plate 9 is fixedly arranged on the transverse vertical plate 4, and an extrusion rotating rod 10 is also rotatably arranged on the transverse vertical plate 4. An I-shaped rotating plate 11 is fixedly arranged on the extrusion rotating rod 10, and an extrusion wheel 12 is rotatably arranged on the I-shaped rotating plate 11. The extrusion wheel 12 is in rolling connection with the buffer ring 306. A torsion spring 13 is slidably sleeved on the extrusion rotating rod 10. One end of the torsion spring 13 is fixedly connected with the limiting plate 9, and the other end of the torsion spring 13 is connected with the I-shaped rotating plate 11. When the buffer ring 306 is sleeved on the bearing ring 6, the torsion spring 13 presses on the I-shaped rotating plate 11, so that the I-shaped rotating plate 11 can press on the extrusion wheel 12, and further the extrusion wheel 12 can press on the buffer ring 306, making a section of the buffer ring 306 located at the extrusion wheel 12 in a bent state. The extrusion wheel 12 extrudes the buffer ring 306, so that the buffer ring 306 can be kept tight on the bearing ring 6, and further the buffer ring 306 can be prevented from contacting the ground, improving safety. And when clamping the long board 309 and pushing the buffer ring 306 to move onto the rolling roller, the buffer ring 306 will tilt, and further the buffer ring 306 will be tightened. The tightened buffer ring 306 can press on the extrusion wheel 12, so that the extrusion wheel 12 presses on the torsion spring 13 through the I-shaped rotating plate 11. At this time, the torsion spring 13 stores energy and contracts, ensuring that the bent part of the buffer ring 306 can be tightened, and further enabling the buffer ring 306 to be tightened and relaxed, facilitating the buffer ring 306 to be sleeved on the rolling roller; In this embodiment, referring to Figure 7 , the mud scraping mechanism 2 includes a connecting rod 201, a mud scraping plate 202 and two rotating cylinders 203. The connecting rod 201 is fixedly arranged between the two transverse vertical plates 4. The two rotating cylinders 203 are sleeved on the connecting rod 201. The mud scraping plate 202 is fixedly arranged on the two rotating cylinders 203. One end of the mud scraping plate 202 away from the rotating cylinder 203 is in sliding connection with the rolling wheel 1. When the rolling wheel 1 rotates, it can rotate relative to the mud scraping plate 202, so that the mud scraping plate 202 can scrape off the mud adhered to the rolling wheel 1, improving the cleanliness of the rolling wheel 1, and further improving the flatness of the roadbed after rolling; Among them, both of the two rotating cylinders 203 are rotatably sleeved on the connecting rod 201. A transverse support plate 14 is also fixedly arranged between the two transverse vertical plates 4. An electric push rod 15 is fixedly arranged on the transverse support plate 14. One end of the output shaft of the electric push rod 15 slidably passes through one side surface of the transverse vertical plate 4 and contacts the mud scraping plate 202. Starting the electric push rod 15 can push the mud scraping plate 202 to rotate, so that the mud scraping plate 202 rotates around the connecting rod 201 through the rotating cylinder 203. Further, one end of the mud scraping plate 202 can approach the rolling wheel 1 to clean the mud on the rolling wheel 1. Controlling the electric push rod 15 away from the mud scraping plate 202 enables the mud scraping plate 202 to fall by gravity, and further enables the mud scraping plate 202 to be away from the rolling wheel 1, facilitating the discharge of the accumulated mud on the mud scraping plate 202, improving the cleanliness of the mud scraping plate 202, and further improving the mud scraping effect; In this embodiment, referring to Figures 1-2 , a protective top plate 16 and a protective bottom plate 17 are also detachably arranged between two transverse vertical plates 4 by screws. Both the protective bottom plate 17 and the protective top plate 16 are located at one end of the transverse vertical plates 4. The U-shaped seat 303 is located between the protective bottom plate 17 and the protective top plate 16. The protective top plate 16 and the protective bottom plate 17 can protect and shield the push-pull electromagnet 305 to prevent the push-pull electromagnet 305 from being damaged, and the protective top plate 16 and the protective bottom plate 17 can play the role of a bumper beam. Since both the protective bottom plate 17 and the protective top plate 16 are installed on the transverse vertical plates 4 by screws, the protective bottom plate 17 and the protective top plate 16 can be removed by removing the screws, which is convenient for placing the protective bottom plate 17 and the protective top plate 16 on the front and rear sides of the rolling wheel 1 to improve the stability of the rolling wheel 1 during transportation. Compared with the sleepers for fixing, the protective bottom plate 17 and the protective top plate 16 have a higher matching degree with the rolling wheel 1, making the stability of the rolling wheel 1 higher; Among them, a protective cover 18 is also fixedly arranged between the two transverse vertical plates 4. The protective cover 18 is located at one end of the transverse vertical plates 4 away from the protective top plate 16. The rolling wheel 1 is located between the protective cover 18 and the protective top plate 16. The squeezing wheel 12 and the transverse support plate 14 are both located inside the protective cover 18. A mounting seat 19 is fixedly arranged on one side of the protective cover 18 away from the squeezing wheel 12. The protective cover 18 can protect and shield the mud scraping plate 202, the squeezing wheel 12, the electric push rod 15 and the torsion spring 13 to prevent the mud scraping plate 202, the squeezing wheel 12, the electric push rod 15 and the torsion spring 13 from being affected by the external environment, improving the stability; The mud scraping plate 202 is located on one side of the rolling wheel 1 close to the mounting seat 19. The mud scraping plate 202 is located between the rolling wheel 1 and the protective cover 18, so that the mud scraping plate 202 is located on the side close to the engineering vehicle, that is, the rear side in the advancing direction of the rolling wheel 1, so that the scraped mud can fall to the rear side of the annual ring, which is convenient for the staff to clean and collect the mud with strong adhesion and hard texture, avoiding the mud with strong adhesion from adhering to the rolling wheel 1 again, and avoiding the hard texture mud from being embedded in the roadbed, so as not to affect the roadbed construction.

[0019] A use method of a roadbed and pavement compaction device for highway construction includes the following steps: S1: Fix the mounting seat 19 on the engineering vehicle, which can integrate the transverse vertical plates 4 and the rolling wheel 1 with the engineering vehicle, and can electrically connect the push-pull electromagnet 305 and the electric push rod 15 with the engineering vehicle, facilitating the control of the opening and closing of the push-pull electromagnet 305 and the electric push rod 15. The engineering vehicle can drive the rolling wheel 1 to move to compact the roadbed; S2: Rotate the mud scraping plate 202 to separate it from the rolling wheel 1. By rotating the mud scraping plate 202 through the electric push rod 15, the working state of the mud scraping plate 202 can be controlled, and then the working state of the rolling wheel 1 can be conveniently controlled; S3: Use the electromagnet to push the clamping long plate 309 to move, so that the clamping long plate 309 squeezes a section of the buffer ring 306 from the bearing ring 6 onto the rolling wheel 1, and the rolling wheel 1 can roll the buffer ring 306 when rotating; S4: Rotate the I-shaped rotating plate 11 to drive the extrusion wheel 12 to rotate, release the buffer ring 306, so that the buffer ring 306 has a tension-relaxing effect, which can prevent the buffer ring 306 from breaking; S5: After the buffer ring 306 is completely sleeved on the rolling wheel 1, rotate the I-shaped rotating plate 11 to drive the extrusion wheel 12 to reset. The extrusion wheel 12 presses the buffer ring 306 to make the buffer ring 306 tight. When the rolling wheel 1 rotates more than one circle, the buffer ring 306 can be gradually sleeved on the rolling wheel 1.

[0020] Based on the above, the working principle of using this solution is as follows: When in use, first install the mounting seat 19 on the engineering vehicle. The engineering vehicle can drive the rolling wheel 1 to move and rotate, and can perform rolling operations. When rolling the roadbed, start the electric push rod 15 to push the mud scraping plate 202 to rotate, so that the mud scraping plate 202 can approach the rolling wheel 1 to clean the rolling wheel 1. When the mud accumulates on the mud scraping plate 202, control the telescopic movement of the electric push rod 15, so that the mud scraping plate 202 falls by gravity, and the mud accumulated on the mud scraping plate 202 can be discharged. When transportation is needed, start the push-pull electromagnet 305, so that the push-pull electromagnet 305 can drive the moving plate 304 to move through the connecting plate 307, and then can drive the clamping long plate 309 to squeeze the buffer ring 306, so that the buffer ring 306 can move from the bearing ring 6 to the rolling wheel 1 along the guide ring 5; As the rolling wheel 1 rotates, a section of the buffer ring 306 will be rolled under the rolling wheel 1. After the rolling wheel 1 rotates more than one circle, the buffer ring 306 can be sleeved on the rolling wheel 1. When the rolling wheel 1 rotates, it can drive the buffer ring 306, the auxiliary wheel 302 and the extrusion wheel 12 to rotate. At this time, the vehicle can be transferred. After the transfer is completed, control the push-pull electromagnet 305 to contract. At this time, the push-pull electromagnet 305 can pull the moving plate 304 to reset through the connecting plate 307, so that the clamping short plate 308 can push one end of the buffer ring 306 to move onto the bearing ring 6. After the rolling wheel 1 rotates more than one circle, the buffer ring 306 can be sleeved on the bearing ring 6. When the buffer ring 306 is sleeved on the bearing ring 6, at this time, the torsion spring 13 pushes the I-shaped rotating plate 11 to rotate, which can drive the extrusion wheel 12 to squeeze the buffer ring 306, so that the buffer ring 306 remains tight. At this time, the roadbed can be rolled.

[0021] Although embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
