A recycled cement concrete pavement base material paving equipment

Abstract

This invention relates to the field of recycled pavement base paving equipment, and in particular to a recycled cement concrete pavement base material paving equipment. Addressing the problem in existing technologies where vibrating rods always move in a straight line, easily causing longitudinal concrete breakage, this invention provides a recycled cement concrete pavement base material paving equipment. It includes a rotatable vibrating cylinder that rotates when an automatic paver moves. Multiple detachable vibrating rods are mounted on the circumferential surface of the vibrating cylinder. During use, the vibrating cylinder rotates synchronously with the automatic paver, moving at the same speed. As the automatic paver moves, the vibrating cylinder rotates synchronously, allowing the vibrating rods to be inserted into the base material sequentially to vibrate it and then withdrawn as the cylinder rotates. This prevents the vibrating rods from moving within the base material and causing longitudinal concrete breakage.

Description

Technical Field

[0001] This invention relates to the field of recycled road base paving equipment, and in particular to a recycled cement concrete road base material paving equipment. Background Technology

[0002] Over time, concrete pavements gradually age due to factors such as temperature, weathering, and moisture, leading to problems like cracking, peeling, and rutting, thus reducing their lifespan. Traditional maintenance methods involve removing the old pavement and repaving it, which is not only time-consuming and labor-intensive but also wasteful and causes significant environmental pollution. Currently, by employing concrete pavement recycling technology, environmental pollution can be minimized, reducing the transportation and processing of broken concrete, while saving substantial amounts of building materials such as stone and asphalt. It also reduces road congestion and traffic accidents caused by road excavation, allowing for faster repairs and minimizing disruption to road traffic.

[0003] Currently, when using concrete pavement recycling technology to construct the pavement base layer, the old pavement needs to be crushed to form old base material. After the old pavement is crushed, new base material is spread and mixed with the old base material, and then compacted. When the paving equipment is used, the base material is spread by methods such as material distribution, vibration, and pre-compaction. During the paving process, since the vibrator always moves in a straight line, the coarse aggregate is pushed aside and can only be filled by mortar. However, the shrinkage rate of mortar is greater than that of cement concrete, so the initial setting agent will crack along the direction of the vibrator. Furthermore, the shrinkage of the concrete will amplify these cracks, which can easily cause longitudinal slab breakage of the concrete and affect the construction quality. Summary of the Invention

[0017] This invention features a novel structure, ingenious design, and simple and convenient operation, offering the following advantages compared to existing technologies:

[0018] When in use, the vibrating cylinder of this device can rotate along with the movement of the automatic paver, and the rotation speed is the same as that of the automatic paver. When the automatic paver moves, the vibrating cylinder can rotate synchronously. When the vibrating cylinder rotates, the vibrating rods can be inserted into the base material in turn to vibrate the base material and then pulled out under the rotation of the vibrating cylinder. The rotation of the vibrating cylinder can make the vibrating rods continuously inserted into the base material, avoiding the situation where the vibrating rods move in the base material and cause longitudinal breakage of the concrete slab.

[0019] When spreading the base material, the rotation of the first and second augers can spread the new base material evenly on the road surface. Since the spiral blades on both sides of the first and second augers rotate in opposite directions, the rotation of the second auger can push the new base material outward for spreading. After spreading, the rotation of the first auger will spread the excess new base material inward again, thereby improving the uniformity of the base material spreading and improving the spreading effect.

[0020] During paving, the first mounting plate can be controlled to move upwards. Driven by the first mounting plate, the height of the second auger is higher than that of the first auger. When the first and second augers rotate, the second auger provides the first stage of paving for the new base material. After the second auger completes the paving, the first auger performs the second stage of paving. Since the first auger is lower than the second auger, when the first auger rotates to pave the new base material, it can compact the new base material on the downward side, further improving the paving effect.

Detailed Implementation

[0043] The following are specific embodiments of the present invention, and the technical solutions of the present invention will be further described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0044] like Figure 1-21As shown, this invention provides a recycled cement concrete pavement base material paving equipment, including an automatic paver 1. The automatic paver 1 includes a traveling mechanism, a material distributing mechanism, a vibration mechanism, and a smoothing mechanism. The material distributing mechanism includes two correspondingly arranged first auger rods 25 and second auger rods 26. The surfaces of the first auger rods 25 and second auger rods 26 are respectively provided with helical blades with oppositely oriented threads at both ends. The front and rear ends of the first auger rods 25 are respectively rotatably connected to second mounting plates 43. The front and rear ends of the second auger rods 26 are respectively provided with first mounting plates 42 that can move up and down. The end of the second mounting plate 43 corresponding to the first mounting plate 42 is provided with a vertically formed docking groove 36. The ends of the first mounting plate 42 and the second mounting plate 43 are fixedly connected to... The docking slider 37 is slidably connected to the docking groove 36, allowing the first mounting plate 42 to slide on the surface of the second mounting plate 43. The front and rear ends of the second spiral rod 26 are respectively rotatably connected to the mounting sliders 44 that can move left and right. The mounting sliders 44 are slidably connected to the surface of the first mounting plate 42. When the mounting sliders 44 move left and right on the surface of the first mounting plate 42, the distance between the first spiral rod 25 and the second spiral rod 26 can be adjusted. When the first mounting plate 42 moves up and down on the surface of the second mounting plate 43, it can drive the second spiral rod 26 to move synchronously. The rear side of the first spiral rod 25 and the second spiral rod 26 is equipped with a driving structure. Under the drive of the driving structure, the first spiral rod 25 and the second spiral rod 26 can be driven to rotate synchronously in opposite directions.

[0045] In use, this device distributes the new base material through a material distribution mechanism. The rotation of the first auger 25 and the second auger 26 ensures the new base material is evenly spread on the road surface. Because the spiral blades on both sides of the first auger 25 and the second auger 26 rotate in opposite directions, the rotation of the second auger 26 pushes the new base material outwards for spreading. After spreading, the rotation of the first auger 25 re-spreads any excess new base material inwards, thus improving the uniformity of the new base material spreading and enhancing the paving effect. Furthermore, to improve… The high paving effect can be achieved by controlling the first mounting plate 42 to move upward. Driven by the first mounting plate 42, the height of the second auger 26 is higher than that of the first auger 25. When the first auger 25 and the second auger 26 rotate, the second auger 26 provides primary paving for the new base material. After the second auger 26 has completed paving, the first auger 25 performs secondary paving. Furthermore, since the first auger 25 is lower than the second auger 26, when the first auger 25 paves the new base material by rotating, it can compact the new base material on the downward side, further improving the paving effect.

[0046] The vibration mechanism includes a rotatable vibrating cylinder 4, with both ends of the cylinder 4 rotatably connected to the front and rear ends of the protective shell 2, respectively. A drive wheel 3 is fixedly connected to the rear end of the vibrating cylinder 4, and the drive wheel 3 is connected to the power output end of the transmission system of the walking mechanism. When the automatic paver 1 moves, it can drive the vibrating cylinder 4 to rotate. Multiple detachable vibrating rods 7 are respectively installed on the circumferential surface of the vibrating cylinder 4. After the base material is spread by the first spiral rod 25 and the second spiral rod 26, the base material is vibrated by the vibrating rods 7. The vibrating cylinder 4 is driven by the drive wheel 3. Under the transmission of the walking mechanism, the rotation speed of the drive wheel 3 can be equal to the rotation speed of the automatic paver 1. When the automatic paver 1 moves, the vibrating cylinder 4 can rotate synchronously. When the vibrating cylinder 4 rotates, the vibrating rod 7 can be inserted into the base material in sequence to vibrate the base material and pulled out under the rotation of the vibrating cylinder 4. Under the rotation of the vibrating cylinder 4, the vibrating rod 7 can be continuously inserted into the base material, avoiding the situation where the vibrating rod 7 moves in the base material and causes longitudinal slab breakage of the concrete.

[0047] A protective cover is provided on the upper side of the material distribution mechanism and the vibration mechanism. The protective cover is fixedly connected to the automatic paver 1 and is used to protect the material distribution mechanism and the vibration mechanism. A transverse mounting groove is provided on the surface of the first mounting plate 42. A mounting slider 44 is slidably connected inside the mounting groove. A third pin 45 is fixedly connected to the outer end of the mounting slider 44. An adjustable plate 46 that can move up and down is provided on the outer side of the first mounting plate 42. An adjusting groove 47 is provided on the surface of the adjusting plate 46. The third pin 45 is slidably engaged inside the adjusting groove 47. When the adjusting plate 46... When moving downwards, the sliding engagement between the adjusting groove 47 and the third pin 45 pushes the mounting slider 44 to move along the mounting groove. A pusher 48 is fixedly connected to the upper ends of the two adjusting plates 46. A connecting plate is fixedly connected to the upper ends of the two corresponding second mounting plates 43. Stabilizing plates 49 are fixedly connected to the front and rear sides of the upper end of the connecting plate. The pusher 48 is slidably connected to the stabilizing plates 49. An adjusting screw 50 is threadedly connected to the middle of the pusher 48. The bottom of the adjusting screw 50 is rotatably connected to the connecting plate, and the upper end of the adjusting screw 50 is coaxial. A second motor 51 is provided, which is fixedly connected to the inner wall of the protective shell 2. The output end of the second motor 51 is fixedly connected to the upper end of the adjusting screw 50. The height of the second screw rod 26 can be controlled by rotating the second motor 51. When the second motor 51 rotates, it drives the adjusting screw 50 to rotate. When the adjusting screw 50 rotates, it drives the push frame 48 to move up and down through a threaded connection with the push frame 48. The push frame 48 can move up and down stably through a sliding connection with the stabilizing plate 49. When the pusher 48 moves downward, it can drive the adjusting plate 46 to move downward, thereby pushing the mounting slider 44 to move inside the mounting groove. When the mounting slider 44 moves, the second spiral rod 26 will also move synchronously, thereby adjusting the distance between the second spiral rod 26 and the first spiral rod 25. When there is too much base material, the distance between the first spiral rod 25 and the second spiral rod 26 can be increased, which is not only conducive to spreading the base material, but also prevents the base material from falling onto the surface of the first spiral rod 25 when the second spiral rod 26 is spreading, thus affecting the spreading of the first spiral rod 25.

[0048] The upper and lower sides of the adjustment groove 47 are respectively inclined grooves and straight grooves, and the inclined grooves are connected to the straight grooves. When the adjustment plate 46 moves downwards and the inclined groove contacts the third pin 45, it can push the mounting slider 44 to move inside the mounting groove. When the height of the second spiral rod 26 is level with the height of the first spiral rod 25, the third pin 45 is located in the straight groove. When the height of the second spiral rod 26 is adjusted upwards, the cooperating pin 24 will move in the straight groove without affecting the distance between the first spiral rod 25 and the second spiral rod 26.

[0049] The outer ends of the first mounting plate 42 are fixedly connected to the first pin 38. The upper ends of the second mounting plate 43 are hinged to a swing plate 39 that can swing left and right. A connecting shaft is fixedly connected between the two swing plates 39. A key-shaped groove is opened on the surface of the swing plate 39. The first pin 38 slides in cooperation with the inner wall of the key-shaped groove. A second hydraulic rod 40 is rotatably connected to the front end of the second mounting plate 43. The power output end of the second hydraulic rod 40 is hinged to the surface of the swing plate 39. The second hydraulic rod 40 is used to control the height adjustment of the second screw rod 26. When the second hydraulic rod 40 is activated, it can push the swing plate 39 to swing. When the swing plate 39 swings, the second hydraulic rod 40 can also rotate around the connection point rotatably connected to the second mounting plate 43, thereby pushing the swing plate 39. When the swing plate 39 swings, it can push the first mounting plate 42 to move upward through the sliding cooperation between the key-shaped groove and the first pin 38, thereby adjusting the height of the second screw rod 26.

[0050] A matching slider is fixedly connected to the outer end of the second mounting plate 43. A transverse matching groove is opened on the surface of the protective shell 2 corresponding to the matching slider. The matching slider is slidably connected to the matching groove. A second pin 41 is fixedly connected to the middle part of the outer end of the matching slider. A first hydraulic rod 35 is rotatably connected to the front and rear sides of the protective shell 2. The power output end of the first hydraulic rod 35 is hinged to the second pin 41. The first hydraulic rod 35 is used to control the distance between the material distribution mechanism and the vibration mechanism, so as to facilitate adjustment according to the needs of the base material paving. When the first hydraulic rod 35 is driven, it can push the matching slider to move through the hinge with the second pin 41. When the matching slider moves, it can drive the second mounting plate 43 to move, and then drive the first mounting plate 42 to move, so as to achieve the effect of moving the material distribution mechanism.

[0051] The drive structure includes a first rotating gear 29 fixedly connected to the rear ends of the first helical rod 25 and the second helical rod 26, respectively. A first transmission gear 30 meshes with the inner side of the first rotating gear 29. A first transmission bevel gear 31 is coaxially fixedly connected to the rear side of the first transmission gear 30. A second transmission bevel gear 32 meshes with the rear side of the first transmission bevel gear 31. A transmission shaft 34 is fixedly connected to the middle of the second transmission bevel gear 32 on the left side, and a transmission cylinder 33 is fixedly connected to the middle of the second transmission bevel gear 32 on the right side. The transmission shaft 34 is splinedly connected to the transmission cylinder 33. The surfaces of the transmission cylinder 33 and the transmission shaft 34 rotate. A coupling plate 52 is connected. The left coupling plate 52 is rotatably connected to the left first transmission gear 30 and the first rotating gear 29, respectively. The right coupling plate 52 is rotatably connected to the right first transmission gear 30. A drive gear 28 meshes with the right side of the right first rotating gear 29. A first motor 27 is provided behind the drive gear 28. The first motor 27 is fixedly connected to the second mounting plate 43. The power output end of the first motor 27 is fixedly connected to the middle of the drive gear 28. The first motor 27 is used to drive the first helical rod 25 and the second helical rod 26 to rotate synchronously in opposite directions. When the first motor 27 rotates, it can drive the drive gear 28 to rotate. When the drive gear 28 rotates, it drives the first spiral rod 25 to rotate through the transmission with the first rotating gear 29 on the right. The rotation of the first spiral rod 25, in turn, is achieved through the transmission of the first transmission gear 30, the first transmission bevel gear 31, the second transmission bevel gear 32, the transmission cylinder 33, and the transmission shaft 34, resulting in the synchronous and opposite rotation of the first spiral rod 25 and the second spiral rod 26. Since the transmission cylinder 33 and the transmission shaft 34 are splined, the inner wall of the transmission cylinder 33 has multiple limiting protrusions, and the surface of the transmission shaft 34 has multiple limiting grooves that slide in conjunction with the limiting protrusions. With the sliding fit, when the drive shaft 34 rotates, it can drive the drive cylinder 33 to rotate. When the distance between the first screw rod 25 and the second screw rod 26 is adjusted, the drive shaft 34 can move axially inside the drive cylinder 33 without affecting the transmission between the drive cylinder 33 and the drive shaft 34. Under the action of the connecting plate 52, when the height of the first mounting plate 42 is adjusted, the drive shaft 34 can be driven to move axially inside the drive cylinder 33, and the connecting plate 52 on the right side can be driven to swing upward with the first rotating gear 29 on the right side as the axis, without affecting the transmission between the first screw rod 25 and the second screw rod 26.

[0052] Multiple connecting guide rails 5 are fixedly connected to the circumferential surface of the vibrating cylinder 4. Multiple connecting sliders 6 are slidably connected to the surface of the connecting guide rails 5. The vibrating rod 7 is detachably connected to the corresponding connecting slider 6. One end of the connecting slider 6 is fixedly connected to a mating pin 24. A guide plate 16 is provided on one side of the connecting guide rail 5. Sliding plates 17 are fixedly connected to the front and rear ends of the guide plate 16. The sliding plates 17 are slidably connected to the end face of the vibrating cylinder 4. The surface of the guide plate 16 is provided with guide grooves 23. The guide grooves 23 on both sides of the surface of the guide plate 16 are... The inclined directions of the moving grooves 23 are opposite, and the matching pins 24 are respectively slidably engaged with the corresponding moving grooves 23. When the guide plate 16 moves radially along the vibrating cylinder 4, the distance between multiple connecting sliders 6 can be adjusted through the sliding engagement of the moving grooves 23 and the matching pins 24. In use, the movement of the guide plate 16 is controlled. When the guide plate 16 moves, the sliding engagement of the moving grooves 23 and the matching pins 24 can drive the connecting sliders 6 to move on the surface of the connecting guide rail 5, thereby achieving the effect of adjusting the distance between multiple vibrating rods 7.

[0053] A rotating plate 18 is rotatably connected to the front end of the vibrating cylinder 4. The circumferential surface of the rotating plate 18 is hinged with a number of hinge rods 19 equal to the number of sliding plates 17. The other end of the hinge rods 19 is hinged to the inner end of the sliding plates 17. A worm gear 20 is fixedly connected to the surface of the rotating plate 18 on the same axis. A worm 21 is meshed on the lower side of the worm gear 20. The worm 21 is rotatably connected to the surface of the vibrating cylinder 4. A drive motor 22 is provided at one end of the worm 21. The drive motor 22 is fixedly connected to the end face of the vibrating cylinder 4. The power output end of the drive motor 22 is fixedly connected to the coaxial axis of the worm 21.

[0054] The connecting slider 6 has a rectangular groove inside, and a circular hole is formed at the upper end of the connecting slider 6, penetrating the rectangular groove. Movable grooves 9 are formed on the left and right sides of the rectangular groove. A movable guide rail 8, which can move back and forth, is slidably connected inside the rectangular groove. Both ends of the movable guide rail 8 are slidably connected to the movable grooves 9. A movable slider 10, which can move along the length of the movable guide rail 8, is slidably connected to the surface of the movable guide rail 8. A threaded connecting cylinder 11 is fixedly connected to the upper end of the movable slider 10. A threaded hole is provided downwards, and a connecting screw 15 is fixedly connected to the bottom of the vibrating rod 7. The connecting screw 15 is threadedly connected to the threaded hole. When installing the vibrating rod 7, the threaded connection between the connecting screw 15 and the threaded hole can be used to move the vibrating rod 7 and the movable slider 10. When the vibrating rod 7 vibrates, the movable slider 10 can move on the surface of the movable guide rail 8. The movable guide rail 8 can also move with the movable slide groove 9. Under the action of the movable slider 10 and the movable guide rail 8, the vibrating rod 7 can be vibrated, providing vibration space for the vibration of the vibrating rod 7.

[0055] Furthermore, to improve the stability of the vibrating rod 7 during use, an annular partition 12 is fixedly connected to the inner wall of the circular hole. A buffer pad 13 is coaxially arranged on the inner side of the annular partition 12. The circumferential surface of the buffer pad 13 has a clamping groove on the inner side, which clamps the surface of the annular partition 12. Multiple annularly distributed buffer springs 14 are fixedly connected to the upper and lower sides of the circumferential surface of the buffer pad 13, respectively. The other end of the buffer spring 14 is fixedly connected to the inner wall of the circular hole. Under the support of the buffer spring 14, the buffer pad 13 can maintain a coaxial arrangement with the circular hole. The vibrating rod 7 is located inside the buffer pad 13. When the vibrating rod 7 vibrates, the buffer pad 13 will move outward due to the vibration. The buffer spring 14 will absorb the vibration force generated by the vibration of the vibrating rod 7, thus supporting the vibrating rod 7.

[0056] In use, this invention can spread new base material through a material distribution mechanism. The rotation of the first auger 25 and the second auger 26 can evenly spread the new base material on the road surface. Since the spiral blades on both sides of the first auger 25 and the second auger 26 rotate in opposite directions, the rotation of the second auger 26 can push the new base material outward for spreading. After spreading, the rotation of the first auger 25 will spread the excess new base material inward again, thereby improving the uniformity of the new base material spreading and improving the spreading effect. When vibrating the road surface, the vibrating cylinder 4 can rotate with the movement of the automatic paver 1, and the rotation speed of the vibrating cylinder 4 is equal to the movement speed of the automatic paver 1. When the vibrating cylinder 4 rotates, it can drive the vibrating rod 7 to continuously insert into the base material for vibration and then pull it out, which can avoid the problems caused by the linear movement of the vibrating rod 7 when the automatic paver 1 moves.

Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of the invention or exceeding the scope defined by the appended claims.
