Description

Technical Field

[0001] This invention relates to the field of prefabricated road technology, and in particular to a paving device and method for prefabricated road construction. Background Technology

[0002] In the field of road construction, traditional concrete pavement has gradually failed to meet the demands of modern engineering for efficient, environmentally friendly and sustainable construction due to problems such as long construction cycle, large pollution from on-site pouring, high maintenance costs and difficulty in recycling.

[0003] Against this backdrop, prefabricated roads have emerged as a new form of road construction. Compared with traditional cast-in-place concrete pavements, prefabricated roads have significant advantages such as safety and aesthetics, high construction efficiency, low construction cost, and recyclability. Their core component—prefabricated road slabs—is produced in factories, which not only ensures the standardization and stability of product quality but also enables rapid, flexible, and orderly on-site assembly and construction, greatly improving the industrialization level of road construction.

[0004] However, in existing prefabricated road construction, the paving process usually involves directly using hoisting equipment. To move and position the hoisting equipment, it is often necessary to pre-install a dedicated track system on both sides of the road. The track is used to transport and guide the hoisting equipment to lay the prefabricated slabs. This track-dependent construction method has obvious drawbacks: on the one hand, the installation, fixing, and subsequent dismantling of the track are cumbersome, taking up a lot of time in the early preparation and later cleanup, thus restricting the overall construction efficiency; on the other hand, the construction of the track system itself also increases additional material and labor costs, limiting the application of this technology in flexible, small-scale, or complex terrain scenarios.

[0005] Therefore, developing a specialized paving equipment that can break free from dependence on fixed tracks, is highly mobile and flexible, and provides precise and efficient paving has become a practical need to promote the further development of prefabricated road technology. Summary of the Invention

[0006] To overcome the above deficiencies, the present invention provides a prefabricated road construction paving equipment and its usage method. The equipment, through an adjustable support mechanism and adjustment mechanism, enables the smooth hoisting and horizontal adjustment of prefabricated road blocks, thereby improving paving efficiency and road surface quality.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a prefabricated road construction paving device, comprising a frame, a front guard at the front end of the frame, a support bracket at the bottom of the frame, a support frame connected below the front guard, tires rotatably mounted on both sides of the support frame and the side of the support bracket, a movable seat slidably mounted on the frame, two steel wire ropes symmetrically connected to both sides of the movable seat, a precast road block disposed below the movable seat, and four steel wire ropes fixedly connected to the surface of the precast road block via connectors; a support mechanism is provided between the four steel wire ropes, the support mechanism including two pressure plates, the four steel wire ropes respectively looped on the two pressure plates; hydraulic cylinders are fixedly mounted at both ends of the front guard, the driving end of the hydraulic cylinders is fixedly connected to the support frame, an opening is provided on the support frame, an adjustment mechanism is provided in the opening, an adjustment plate is connected to the adjustment mechanism, and the adjustment plate adjusts the angle of the precast road block through the adjustment mechanism.

[0009] As a further description of the above technical solution:

[0010] The motor is located at one end of the movable seat near the front guard. Multiple grooves are provided on the bottom surface of the slide groove to enhance the friction of the roller and prevent slippage.

[0011] As a further description of the above technical solution: the support mechanism also includes multiple fourth cylinders installed between the two pressure plates. The fourth cylinder is fixedly connected to one of the pressure plates, and the drive end of the fourth cylinder is fixedly connected to the other pressure plate. Both ends of the pressure plates are fixedly provided with connecting ropes, and the upper end of the connecting ropes is fixedly connected to the moving seat. The opening and closing of the pressure plates is controlled by the extension and retraction of the fourth cylinders, thereby adjusting the spacing of the cross points of the wire ropes and realizing the lifting and lowering of the precast road blocks.

[0012] As a further description of the above technical solution: the two pressure plates are respectively located on both sides below the movable seat. The steel wire rope on one side of the movable seat passes over the surface of the pressure plate on the other side, and the steel wire rope is connected to the surface of the precast road block on the same side. Two intersection points are formed between the steel wire ropes on the left and right sides, and the two intersection points are respectively located on the upper and lower sides of the pressure plate. The height of the precast road block is controlled by changing the distance between the intersection points by moving the pressure plate.

[0013] As a further description of the above technical solution: multiple slots are provided on the edges of both sides of the movable seat, and the slots are used to engage the wire rope to prevent the wire rope from shifting.

[0014] As a further description of the above technical solution: the adjustment mechanism includes a first adjustment shaft, a second adjustment shaft, and a third adjustment shaft. The second adjustment shaft and the third adjustment shaft are rotatably connected together. One end of the first adjustment shaft and the third adjustment shaft are rotatably connected to the opening through a mounting block. The other end of the first adjustment shaft is rotatably connected to one end of one side of the adjustment plate, and the other end of the second adjustment shaft is rotatably connected to the other end of the adjustment plate. The adjustment mechanism also includes a first cylinder, a second cylinder, and a third cylinder, all rotatably installed in a hydraulic cylinder. The driving end of the first cylinder is rotatably connected to the second adjustment shaft, the driving end of the third cylinder is slidably connected to the first adjustment shaft, and the driving end of the second cylinder is rotatably connected to the third cylinder.

Through the coordinated action of each cylinder, the adjustment shaft is driven to rotate, thereby adjusting the tilt angle of the adjustment plate.

[0016] As a further description of the above technical solution: the driving end of the hydraulic cylinder is fixedly connected to a mounting plate, and the mounting plate is fixedly connected to the support frame by screws.

[0017] A method for using a prefabricated road construction paving equipment includes the following steps:

[0018] Step 1: Extend the hydraulic cylinder drive end to push the support frame down so that the bracket and the tires of the support frame are in contact with the ground and are horizontal; push the equipment to the starting position of the prefabricated road construction, at which point the front windshield faces the paving direction;

[0019] Step 2: Place the precast road block directly below the moving seat on the ground, control the retraction of the fourth cylinder drive end, bring the two pressure plates closer together, and increase the distance between the steel wire rope intersection points; after fixing the connector to the surface of the precast road block, control the extension of the fourth cylinder drive end, move the two pressure plates away from each other, decrease the distance between the steel wire rope intersection points, and lift the precast road block to the air, 30-50cm above the ground.

[0020] Step 3: Start the motor to drive the rollers to rotate in the chute, which will move the moving seat along the frame in the paving direction; when the precast pavement block moves directly above the base surface to be paved, turn off the motor.

[0021] Step 4: Control the fourth cylinder to retract in stages, the two pressure plates gradually approach each other, and the precast pavement block is slowly lowered to 5-10cm from the paving base surface; start the second cylinder, its drive end extends and retracts to change the tilt angle of the third cylinder, the drive end of the third cylinder slides in the adjustment groove through the slider, driving the first adjustment shaft to rotate, adjusting the height of one side of the adjustment plate; at the same time, start the first cylinder, its drive end extends and retracts to pull the second adjustment shaft to rotate, adjusting the height of the other side of the adjustment plate; until the adjustment plate is in contact with the upper surface of the precast pavement block and the levelness error of the precast pavement block is ≤0.5°, stop the calibration;

[0022] Step 5: Control the fourth cylinder to fully retract, and lower the precast road block to the paving base; control the hydraulic cylinder drive end to retract, the distance between the front windshield and the support frame decreases, and the tires of the support frame press the paved precast road block tightly; push the equipment forward, and the support frame simultaneously compacts the paved road surface. The compaction pressure is adjusted by the hydraulic cylinder to complete the paving of a section of the road; repeat steps 2 to 5 until the entire prefabricated road is paved.

[0023] The present invention has the following beneficial effects:

[0024] 1. In this invention, by setting up a support mechanism consisting of a pressure plate, a fourth cylinder, and steel wire ropes, and combining it with a movable seat that can slide along the frame, the precast road blocks are directly hoisted and horizontally transported inside the equipment, eliminating the reliance on fixed tracks in traditional construction. The equipment utilizes tire support and mobility, making it highly mobile and easy to relocate, significantly reducing the construction and dismantling of auxiliary facilities, effectively improving construction efficiency and reducing overall costs. At the same time, by controlling the spacing of the pressure plate to adjust the position of the steel wire rope intersection, the precast road blocks are lifted and lowered smoothly and controllably, avoiding the shaking and impact that are easily generated by traditional hoisting, and ensuring the stability and safety of the paving process.

[0025] 2. In this invention, a precise angle and level adjustment system is formed by installing a hydraulic cylinder between the front windshield and the support frame, and integrating an adjustment mechanism and adjustment plate with multiple cylinders and adjustment shafts on the support frame. This design allows the equipment to fine-tune the precast pavement blocks when they are lowered close to the base surface, ensuring that they are highly level and connected with the paved pavement or base surface. The levelness error can be controlled within 0.5°, greatly improving the overall flatness and quality of the pavement. In addition, the hydraulic cylinder retraction causes the tires of the support frame to press the paved pavement tightly, and the rolling compaction is carried out simultaneously as the equipment moves forward, realizing continuous operation of paving and compaction. This not only simplifies the process but also effectively enhances the density and integrity of the pavement, further ensuring the quality of the project. Attached Figure Description

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Reference Figures 1-7One embodiment of the present invention provides a prefabricated road construction paving device, comprising a frame 1, a front guard 4 at the front end of the frame 1, a support bracket 2 at the bottom of the frame 1, a support frame 5 connected below the front guard 4, and tires 3 rotatably mounted on both sides of the support frame 5 and the sides of the support bracket 2, allowing the device to move on unpaved and paved roads without the need for tracks; a movable seat 7 is slidably mounted on the frame 1, with two steel wire ropes 8 symmetrically connected to both sides of the movable seat 7, and a prefabricated road block 10 disposed below the movable seat 7; the four steel wire ropes 8 are fixedly connected to the surface of the prefabricated road block 10 through connectors 18. The moving seat 7 slides along the frame and hoists the precast road block 10 via the wire rope 8 and the connector 18. A support mechanism is set between the four wire ropes 8. The support mechanism includes two pressure plates 14. The four wire ropes 8 are respectively sleeved on the two pressure plates 14. The two pressure plates 14 control the spacing between the intersection points of the wire ropes to achieve height adjustment. Hydraulic cylinders 6 are fixedly installed at both ends of the front guard 4. The driving end of the hydraulic cylinder 6 is fixedly connected to the support frame 5. An opening 16 is opened on the support frame 5. An adjustment mechanism is set in the opening 16. The adjustment mechanism is connected to an adjustment plate 19. The adjustment plate 19 adjusts the angle of the precast road block 10 through the adjustment mechanism.

[0037] Specifically, rollers 13 are symmetrically rotatably connected to both sides of the movable seat 7. A sliding groove 11 is provided on the frame 1, and the rollers 13 are rotatably disposed in the sliding groove 11. The rollers 13 are embedded in the sliding groove 11 of the frame 1 to form a sliding pair. The sliding groove 11 guides the rollers 13 to ensure stable movement. Two motors 9 corresponding to the rollers 13 are also fixedly installed on both sides of the movable seat 7. The drive end of the motor 9 is fixedly connected to the roller 13, converting the rotational motion of the motor 9 into the linear motion of the movable seat 7. This enables the movable seat 7 to slide smoothly and accurately along the frame 1, providing power and guidance for the conveying of precast road blocks 10.

[0038] Specifically, the motor 9 is located at one end of the movable seat 7 near the front stop 4, which shortens the power transmission path and reduces transmission loss; multiple grooves are opened on the bottom surface of the slide 11 to increase the friction between the roller 13 and the slide 11, prevent slippage when conveying heavy loads, and improve conveying efficiency and positioning accuracy.

[0039] Specifically, the support mechanism also includes multiple fourth cylinders 17 installed between the two pressure plates 14. The cylinders extend and retract to move the pressure plates closer to or further away. The fourth cylinder 17 is fixedly connected to one of the pressure plates 14, and the drive end of the fourth cylinder 17 is fixedly connected to the other pressure plate 14. Both ends of the pressure plate 14 are fixedly provided with connecting ropes 15. The upper end of the connecting ropes 15 is fixedly connected to the movable seat 7. Both ends of the pressure plate 14 are connected to the movable seat 7 through the connecting ropes 15 to keep the pressure plate 14 suspended stably. The wire ropes 8 are looped on the pressure plates. When the pressure plate 14 is pressed, the spacing of the wire ropes 8 will change, thereby controlling the height of the precast blocks and realizing the smooth lifting and lowering of the precast road blocks 10.

[0040] Specifically, the two pressure plates 14 are located on both sides below the movable seat 7. The wire rope 8 on one side of the movable seat 7 passes over the surface of the pressure plate 14 on the other side, and the wire rope 8 is connected to the surface of the precast road block 10 on the same side. There are two intersection points between the wire ropes 8 on the left and right sides. The wire ropes 8 on both sides cross and pass over the pressure plate 14 on the opposite side to form two intersection points at the top and bottom. The two intersection points are located on the top and bottom sides of the pressure plate 14 respectively. The cross arrangement makes the four lifting points evenly stressed, avoids excessive stress on one side, ensures that the wire rope 8 is stressed evenly, improves the lifting stability, and prevents the precast road block 10 from tilting.

[0041] Specifically, multiple slots 12 are provided on the edges of both sides of the movable seat 7. The slots 12 are used to engage the wire rope 8. The wire rope 8 can be engaged into different slots 12 to adjust the spacing between the lifting points; adapting to precast blocks of different widths and weight distributions, thus expanding the versatility of the equipment.

[0042] Specifically, the adjustment mechanism includes a first adjustment shaft 23, a second adjustment shaft 25, and a third adjustment shaft 26. The second adjustment shaft 25 and the third adjustment shaft 26 are rotatably connected together. One end of the first adjustment shaft 23 and the third adjustment shaft 26 is rotatably connected to the opening 16 via a mounting block 28. The other end of the first adjustment shaft 23 is rotatably connected to one end of one side of the adjustment plate 19, and the other end of the second adjustment shaft 25 is rotatably connected to the other end of the other side of the adjustment plate 19. The adjustment mechanism also includes a first cylinder 20, a second cylinder 21, and a third cylinder 22, all rotatably mounted in the hydraulic cylinder 6. The drive end of cylinder 20 is rotatably connected to the second adjustment shaft 25, the drive end of the third cylinder 22 is slidably connected to the first adjustment shaft 23, and the drive end of the second cylinder 21 is rotatably connected to the third cylinder 22; the first adjustment shaft 23, the second adjustment shaft 25, and the third adjustment shaft 26 form a triangular support structure to support the adjustment plate 19; the first cylinder 20 controls the second adjustment shaft 25, and the second cylinder 21 and the third cylinder 22 cooperate to control the first adjustment shaft 23. The multi-cylinder drive multi-axis linkage allows the height of both ends of the adjustment plate 19 to be adjusted independently, achieving precise control of the horizontal or tilt angle and ensuring flat laying.

[0043] Specifically, an adjustment groove 24 is provided on the first adjustment shaft 23. The drive end of the third cylinder 22 is slidably connected to the adjustment groove 24 via a slider 27. The second cylinder 21 is rotatably connected to the upper inner wall of the opening 16. The drive end of the second cylinder 21 is rotatably connected to the bottom of the third cylinder 22. The middle section of the third cylinder 22 is rotatably connected to the bottom of the opening 16. The rotatable connection between the second cylinder 21, the third cylinder 22, and the inner wall of the opening 16 forms a lever structure to achieve effective force transmission. The slider 27 cooperates with the adjustment groove 24 to absorb the displacement deviation caused by the multi-axis rotation, compensate for the displacement change when the adjustment shaft rotates, and ensure smooth angle adjustment without jamming.

[0044] Specifically, the drive end of the hydraulic cylinder 6 is fixedly connected to a mounting plate 30, which is fixedly connected to the support frame 5 by screws 29; this achieves a stable and detachable connection between the hydraulic cylinder 6 and the support frame 5, facilitating maintenance and height adjustment.

[0045] To further illustrate the above embodiments, the present invention also provides a method for using a prefabricated road construction paving device. The specific steps for using this device for prefabricated road construction are as follows:

[0046] Step 1: Start the hydraulic system and extend the drive end of the hydraulic cylinder 6 to push the support frame 5 down until the bracket 2 and all the tires 3 on the support frame 5 are in contact with the ground. Check the level of the frame 1 with a level and adjust the extension of the hydraulic cylinder 6 as necessary to ensure levelness; the operator pushes the equipment (or tows it by a tractor) to the starting position of the prefabricated road construction, with the front windshield 4 facing the paving direction, and the tires 3 providing stable support and adapting to ground undulations during movement;

[0047] Step 2: Use lifting equipment to hoist the precast road block 10 to the ground directly below the moving seat 7, ensuring that the center of the precast road block 10 is aligned with the moving seat 7; control the retraction of the drive end of the fourth cylinder 17 (the amount of retraction is monitored by a sensor), so that the two pressure plates 14 move closer to each other, the distance between the intersections of the wire ropes 8 increases, and the wire ropes 8 slack; fix the connector 18 (such as a quick clamp) to the lifting hole on the surface of the precast road block 10, ensuring a firm connection; control the extension of the drive end of the fourth cylinder 17, so that the pressure plates 14 move further apart, the distance between the intersections of the wire ropes 8 decreases, and the precast road block 10 is lifted; by adjusting the stroke of the fourth cylinder 17, the precast road block 10 is suspended in the air, 30-50cm above the ground;

[0048] Step 3: Start motor 9. Motor 9 drives roller 13 to roll in slide 11, which in turn moves the moving seat 7 along the frame 1 in the paving direction. When the precast road block 10 moves to the top of the base surface to be paved (positioned by position sensor or vision system), turn off motor 9 and the moving seat 7 stops moving.

[0049] Step 4: Control the fourth cylinder 17 to retract in stages, causing the pressure plate 14 to gradually approach and the precast road block 10 to slowly lower until it is 5-10 cm away from the paving base. First, start the second cylinder 21, whose drive end extends and retracts to push the third cylinder 22 to rotate around its middle hinge point, changing the tilt angle of the third cylinder 22. The drive end of the third cylinder 22 slides in the adjustment groove 24 through the slider 27, driving the first adjustment shaft 23 to rotate, thereby adjusting the height of one side of the adjustment plate 19. At the same time, start the first cylinder 20, whose drive end extends and retracts to pull the second adjustment shaft 25 to rotate, adjusting the height of the other side of the adjustment plate 19. During the adjustment process, the adjustment plate 19 contacts the upper surface of the precast road block 10, and the levelness of the precast road block 10 is detected by the tilt sensor until the levelness error is ≤0.5°. After calibration, lock the position of each cylinder.

[0050] Step 5: Control the fourth cylinder 17 to fully retract, and the precast road block 10 is smoothly lowered onto the paving base surface, ensuring no impact; control the drive end of the hydraulic cylinder 6 to retract, reducing the distance between the front guard 4 and the support frame 5, and the tires 3 on the support frame 5 press the paved precast road block 10 tightly; the compaction pressure is adjusted by the pressure valve of the hydraulic cylinder 6 (usually set to 0.5~1MPa); push the equipment forward a distance (equivalent to the length of a precast road block), and the tires 3 of the support frame 5 roll and compact the paved road surface during the movement;

[0051] Repeat steps 2 to 5, hoisting and laying subsequent precast road blocks 10 in sequence until the entire road is paved; after laying every 5 to 10 blocks, check the road surface flatness and recalibrate if necessary.

[0052] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
