Description

Technical Field

[0001] The present invention belongs to the technical field of road construction equipment, and in particular relates to an automatic paving device for prefabricated curbstones and an operating method thereof. Background Art

[0002] Precast curbstones are prefabricated curbstones made of specific materials (such as concrete, granite, etc.) and processes. They are usually used to define the edges of roads, parking lots, and other places. They have the functions of defining road boundaries, protecting the road surface, guiding traffic, and beautifying the environment. When laying curbstones, a curbstone laying device is required; Currently, traditional automatic curb placement devices precisely place suction cups on one side of the top of the curb. A vacuum assembly then activates to extract air from the cups, quickly creating a vacuum and generating a strong negative pressure. This firmly holds the curb in place. The operator then uses the control console to direct the device's mobile chassis along a pre-set route, which in turn drives the suction cups, holding the curb, along the intended paving path. Once the device successfully reaches the paving path, the operator again uses the control console to carefully adjust the suction cups' height, allowing the curb to slowly and steadily descend to its placement position, completing the paving process.

[0003] However, in actual use, due to the complex and ever-changing road conditions, including unevenness and varying slopes, coupled with vibrations during equipment operation and environmental influences, equipment misalignment is a common occurrence. This seemingly minor misalignment can have a significant impact on curb placement. It can disrupt the precise alignment of existing curbs with those to be laid. This not only reduces curb placement accuracy, making it difficult to meet high quality standards, but also significantly increases the workload for subsequent adjustments. Construction workers must expend considerable time and effort re-adjusting and correcting misaligned curbs, significantly reducing construction efficiency. Summary of the Invention

[0013] Preferably, sealing plates are fixedly mounted on both ends of the rack, and the sealing plates are adapted to the connecting shell.

[0014] A method for automatically laying prefabricated curbstones is as follows: S1: The operator places a suction cup on one side of the top of the curb, activates the vacuum assembly to extract the air inside the cup, creating a vacuum state inside the cup and attaching the curb to the cup. The operator then uses the console to control the mobile chassis of the device, causing the entire device to move the suction cup holding the curb to the predetermined paving path. When the device reaches the paving path, the operator again adjusts the height of the suction cup using the console to slowly lower the curb to the paving position. S2: When the vacuum assembly drives the suction cup to fix the curb, the exhaust pipe also extracts air from the sealed shell, creating a negative pressure space inside the sealed shell. The two sliding rods retract into the sealed shell, driving the mounting block, slider, and positioning plate to contact the surface of the curb and push the curb toward the center of the suction cup. When the two positioning plates simultaneously contact the surface of the curb, the curb is fixed in the center of the suction cup, ensuring the accuracy of paving. S3: During the process of lowering and laying the curb, ball bearing 2 will contact the top of the already laid curb and squeeze ball bearing 2, mounting plate 2, and hinge block upwards. The hinge block will push the two hinged rods to rotate. The rotating hinged rods will pull the two sliding rods 1, mounting plate 1, and ball bearing 1 toward the surface of the already laid curb. When the two ball bearings 1 simultaneously contact both sides of the already laid curb, the curb is positioned, ensuring that the curb to be laid is precisely aligned with the already laid curb in both the horizontal and vertical directions. S4: When the curb is laid and the mounting plate 2 is away from the curb, the compressed elastic member 1 will push the sliding plate and the extrusion rod to move. During the sliding process of the extrusion rod, the air inside the fixed shell will be pushed through the one-way valve and the air outlet pipe into the connecting shell. Then the flowing air will push the rack to move, the rack will drive the gear to rotate, and the gear will drive the cam to rotate. The rotating cam will contact the surface of the connecting plate and push the knocking block and the connecting plate to move back and forth. During the movement of the knocking block, it will knock on the surface of the curb, so that the curb and the surrounding base materials are more tightly combined.

[0015] Compared with the prior art, the present invention has the following beneficial effects: The present invention uses the second ball bearing to contact the top of the paved curb stone, and squeezes the second ball bearing, the second mounting plate and the hinge block to move upward. The hinge block pushes the two hinge rods to rotate, and the rotating hinge rod pulls the two sliding rods, the first mounting plate and the first ball bearing to move toward the surface of the paved curb stone. When the two first ball bearings contact both sides of the paved curb stone at the same time, the positioning of the curb stone is completed, ensuring that the curb stone to be laid and the paved curb stone are accurately aligned in both horizontal and vertical directions. Finally, the curb stone to be laid is positioned by driving and squeezing, which greatly improves the accuracy of curb stone laying, allows each curb stone to be neatly arranged, reduces the workload of subsequent adjustments, and significantly improves construction efficiency. The present invention pushes the sliding plate and the extrusion rod to move through the compressed elastic member, which pushes the air inside the fixed shell to pass through the one-way valve and the air outlet pipe into the interior of the connecting shell. The flowing air pushes the rack to move, the rack drives the gear and the cam to rotate, and the cam drives the knocking block to knock the surface of the curb. Finally, the surface of the paved curb is knocked by the compression, so that the curb is more tightly combined with the surrounding base material, thereby enhancing the stability of the curb. The present invention drives the vacuum component to extract the air inside the sealed shell, so that a negative pressure space is generated inside the sealed shell. The two sliding rods 2 are retracted into the sealed shell. The sliding rods 2 drive the mounting block, the slider and the positioning plate to contact the surface of the curb, and push the curb toward the middle of the suction cup. Finally, the curb is positioned in the middle by driving, thereby improving the accuracy of paving, ensuring that each curb can be accurately installed in the predetermined position, and ensuring the neatness and beauty of the road.

DETAILED DESCRIPTION

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] like Figures 1 to 9 As shown, the present invention provides a prefabricated curb automatic laying device, including a main body 100, a vacuum assembly 200 and a suction cup 300, and further comprising: Alignment mechanism 400 is provided on both sides of the top of suction cup 300. Alignment mechanism 400 includes a support shell 401 fixedly connected to both sides of the top of suction cup 300. A square shell 402 is fixedly mounted on the top of support shell 401. Two sliding rods 403 are slidably connected to the interior of square shell 402. The bottom ends of the two sliding rods 403 are fixedly mounted with mounting plates 404. The bottom ends of mounting plates 404 are rollingly connected with balls 405. The driving assembly 500 is disposed on the opposite side of the two sliding rods 403 .

[0020] The above solution is adopted: the operator starts the vacuum component 200 connected to the suction cup 300, and the vacuum component 200 begins to operate efficiently. The powerful air pump inside the suction cup 300 quickly extracts the air inside the suction cup 300. As the air is continuously extracted, the space inside the suction cup 300 gradually forms a vacuum state. In this process, the external atmospheric pressure begins to play a key role. Since the internal air pressure of the suction cup 300 is much lower than the external atmospheric pressure, the huge pressure difference generates a strong negative pressure adsorption force. This negative pressure adsorption force tightly grasps the curbstone. It acts evenly on the contact surface between the suction cup 300 and the curbstone, and firmly adsorbs the curbstone on the suction cup 300 from all directions. Even if there is a certain roughness or slight unevenness on the surface of the curbstone, the negative pressure adsorption force can overcome these tiny obstacles with its powerful force to ensure the stability of the adsorption; at the same time, the suction strength of the air pump is used to ensure the adsorption and fixation of the curbstone.

[0021] Then, the operator controls the mobile chassis of the equipment, so that the entire equipment drives the suction cup 300 holding the curb stone to move to the predetermined paving path. When the equipment reaches the paving path, the operator adjusts the height of the suction cup 300 again through the operator console, so that the curb stone slowly descends to the paving position. During the process of the curb stone being lowered, the driving assembly 500 will first contact the paved curb stone, and the driving assembly 500 will be squeezed by the curb stone and move upward. During the upward movement, the sliding rod 1 403 will be driven to move relative to each other, and the sliding rod 1 403 will drive the mounting plate 1 404 and the ball bearing 1 405 to move toward the surface of the curb stone. When the two ball bearings 1 405 contact both sides of the paved curb stone at the same time, the positioning of the curb stone is completed, ensuring that the curb stone to be laid is aligned with the paved curb stone. The curbs are precisely aligned in both horizontal and vertical directions. After the ball bearing 405 contacts the surface of the curb, the moving curb drives the ball bearing 405 to roll along the surface of the already laid curb, thereby ensuring the smooth movement of the curb. Finally, the extrusion drive assembly 500 is driven to position the curb to be laid, which greatly improves the accuracy of curb laying, allowing each curb to be neatly arranged, reducing the workload of subsequent adjustments, and significantly improving construction efficiency. like Figure 3 and Figure 4 As shown, the drive assembly 500 includes an articulated rod 505 hinged on the opposite side of two sliding rods 403, and the number of the articulated rods 505 is designed to be two. The interior of the support shell 401 is slidably connected to a sliding plate 501, and the sliding plate 501 is elastically connected to the support shell 401 through an elastic member 502. The bottom end of the sliding plate 501 is fixedly installed with a telescopic rod 503, and an elastic member 504 is provided inside the telescopic rod 503. The bottom end of the telescopic rod 503 is fixedly installed with a mounting plate 507, and the bottom end of the mounting plate 507 is internally rolled with a ball 508. One end of the two articulated rods 505 is hinged through a hinge block 506, and the hinge block 506 is fixedly connected to the mounting plate 507.

[0022] With the above solution, through the design of the drive assembly 500, during the process of the curbstone being lowered, the second ball bearing 508 will contact the top of the already laid curbstone. As the curbstone to be laid descends, the already laid curbstone will squeeze the second ball bearing 508 and the second mounting plate 507 upward, and the second mounting plate 507 will drive the hinge block 506 upward. Since one end of the hinge rod 505 is hinged by the hinge block 506, the hinge block 506 will push the two hinge rods 505 to rotate. The rotating hinge rod 505 will pull the two sliding rods 403, the first mounting plate 404 and the first ball bearing 405 toward the surface of the already laid curbstone, thereby accurately positioning the curbstone. At the same time, the second mounting plate 507 also drives the telescopic rod 503 and the sliding plate 501 to move upward. The sliding plate 501 squeezes the elastic member 1 502. By cleverly utilizing the resilience of the elastic member 1 502, the second mounting plate 507 is pushed back to its original position after completing a specific action, preparing for the next positioning operation and ensuring the continuous and stable operation of the equipment. When the surfaces of the two ball bearings 405 come into contact with the surface of the paved curb, the paved curb continues to squeeze the mounting plate 2 507 upward. At this time, the telescopic rod 503 contracts and squeezes the elastic member 2 504. This design effectively avoids the mounting plate 2 507 from getting stuck, achieving accurate, stable and efficient positioning during the curb paving process, and greatly improving the reliability of positioning.

[0023] like Figure 5 、 Figure 6 and Figure 7 As shown, it also includes: The squeezing mechanism 600 is provided at the top of the supporting shell 401. The squeezing mechanism 600 includes a fixed shell 601 fixedly connected to the top of the supporting shell 401. The top of the fixed shell 601 is fixedly installed with an squeezing rod 602, and the squeezing rod 602 is fixedly connected to the sliding plate 501. A one-way valve 603 is provided on one side of the outer surface of the fixed shell 601. An air outlet pipe 604 is fixedly installed on one side of the one-way valve 603. A connecting shell 605 is fixedly installed on one side of the supporting shell 401. One end of the air outlet pipe 604 is connected to one side of the connecting shell 605. A gear 608 is rotatably connected to the interior of the connecting shell 605. A cam 609 located on the outer surface of the connecting shell 605 is fixedly installed on one side of the gear 608. A rack 606 is slidably connected to the interior of the connecting shell 605. The rack 606 and the connecting shell 605 are elastically connected by an elastic member 607. The striking mechanism 700 is disposed on both sides of the outer surface of the supporting shell 401 .

[0024] The above solution is adopted: through the design of the extrusion mechanism 600, when the curb is paved and the mounting plate 2 507 is away from the curb, the compressed elastic member 1 502 will push the sliding plate 501 to reset, and the sliding plate 501 will pull the extrusion rod 602 to slide inside the fixed shell 601. During the sliding process, the air inside the fixed shell 601 will be pushed into the one-way valve 603 and the air outlet pipe 604, and then the flowing air will pass through the air outlet pipe 604 into the connecting shell 605, and will push the gear 608 to move. Because the rack 606 is engaged with the gear 608, the rack 606 will drive the gear 608 to rotate, and the moving gear 608 will squeeze the elastic member 3 607, and then the gear 608 will drive the cam 609 to rotate. During the rotation process, the knocking mechanism 700 will be driven to move back and forth. When the knocking mechanism 700 moves, it will knock the surface of the paved curb. At the same time, when the sliding plate 501 pushes the extrusion rod 602 to move upward, the one-way valve 603 is provided, so that air will not enter the interior of the connecting shell 605. Finally, the cam 609 drives the knocking mechanism 700 to knock on the surface of the paved curb through the compressed elastic member 502, so that the curb is more closely combined with the surrounding base materials, thereby enhancing the stability of the curb.

[0025] like Figure 5 、 Figure 6 and Figure 7 As shown, the knocking mechanism 700 includes a mounting plate three 701 fixedly connected to both sides of the outer surface of the support shell 401, an elastic member four 702 is fixedly installed on the bottom end of the mounting plate three 701, a knocking block 703 is fixedly installed on the bottom end of the elastic member four 702, and a connecting plate 704 located at the bottom end of the cam 609 is fixedly installed on the top end of the knocking block 703.

[0026] like Figure 5 、 Figure 6 and Figure 7 As shown, the bottom end of the knocking block 703 is designed to be arc-shaped, and a rubber pad is provided on the surface of the bottom end of the knocking block 703.

[0027] The above scheme is adopted: through the design of the knocking mechanism 700, during the rotation of the cam 609, it will contact the surface of the connecting plate 704 and squeeze the connecting plate 704 to descend, and the connecting plate 704 will drive the knocking block 703 to descend. When the knocking block 703 descends, the elastic member 4 702 will be stretched, and the resilience of the elastic member 4 702 will be utilized to enable the knocking block 703 and the connecting plate 704 to move back and forth. During the movement of the knocking block 703, it will knock the surface of the curb, so that the curb is more tightly combined with the surrounding base material, and the surface of the bottom end of the knocking block 703 is provided with a rubber pad, so that when it contacts the surface of the curb, the curb can be protected, and the plasticity of the rubber pad is utilized. When the mounting plate 2 507 is away from the curb surface, the knocking block 703 can still continue to knock the surface of the curb under the elastic action of the rubber pad. Continuous knocking can further consolidate the paving effect of the curb.

[0028] like Figure 8 and Figure 9 As shown, it also includes: The positioning mechanism 800 is arranged on one side of the suction cup 300. The positioning mechanism 800 includes a sealing shell 801 fixedly connected to one side of the suction cup 300. Two sliding rods 802 are slidably connected to both ends of the inside of the sealing shell 801. Elastic parts 5 803 are fixedly installed on the opposite sides of the two sliding rods 802. Two exhaust pipes 804 are fixedly installed on the top of the sealing shell 801, and one end of the exhaust pipe 804 is connected to the connecting pipe at the top of the suction cup 300. The top of the two sliding rods 802 is fixedly installed with a mounting block 805. The inside of the mounting block 805 is slidably connected with a slider 806. The slider 806 and the mounting block 805 are elastically connected by an elastic part 6 807. The bottom end of the slider 806 is fixedly installed with a positioning plate 808 located on both sides of the suction cup 300.

[0029] like Figure 8 and Figure 9As shown, a limiting block located on the opposite side of the two sliding rods 802 is fixedly installed inside the sealing shell 801, and the sliding block 806 is T-shaped, and the surface of the sliding block 806 is in contact with the inner wall of the mounting block 805.

[0030] The above solution is adopted: through the design of the positioning mechanism 800, when the vacuum assembly 200 drives the suction cup 300 to absorb and fix the curb, the exhaust pipe 804 will also extract the air inside the sealed shell 801, so that a negative pressure space is generated inside the sealed shell 801. Under the action of the negative pressure, the two sliding rods 802 will be pulled and retracted into the sealed shell 801, and the two sliding rods 802 will squeeze the elastic member 5 803, and then the sliding rod 802 will drive the mounting block 805, the slider 806 and the positioning plate 808 to move. 08 contacts the surface of the curb and pushes the curb toward the middle of the suction cup 300. When the two positioning plates 808 contact the surface of the curb at the same time, the curb can be fixed in the middle of the suction cup 300, thereby ensuring the accuracy of paving. Finally, by driving the vacuum assembly 200, the positioning plate 808 positions the curb in the middle of the suction cup 300, thereby improving the accuracy of paving and ensuring that each curb can be accurately installed in the predetermined position, ensuring the neatness and beauty of the road. At the same time, when the sliding rod 802 moves, it will contact the limit block, thereby ensuring the positioning accuracy of the sliding rod 802. Then, during the paving of the curb, the paved curb will also squeeze the positioning plate 808 to move upward, and the positioning plate 808 will drive the slider 806 to slide inside the mounting block 805. Since the slider 806 is a T-shaped design, the stability of the movement of the slider 806 is ensured. Then the slider 806 will squeeze the elastic part 6 807, and use the upward movement of the positioning plate 808 to not interfere with the paving of the curb.

[0031] like Figure 3 and Figure 6 As shown, a square groove is provided on the surface of the hinge block 506 , there are two ball bearings 508 , and the surface of the ball bearings 508 is smooth. Sealing plates are fixedly installed at both ends of the rack 606 , and the sealing plates are adapted to the connecting shell 605 .

[0032] The above solution is adopted: through the design of the hinge block 506 and the hinge block 506, since a square groove is provided on the surface of the hinge block 506, the hinge block 506 will not interfere with the rotation of the two hinge rods 505, and the surface of the ball 2 508 is designed to be smooth. When the ball 1 405 pushes the curb to move, the ball 2 508 can roll on the top of the paved curb, thereby ensuring that the ball 1 405 can accurately position the curb to be laid. Through the design of the rack 606, since sealing plates are fixedly installed at both ends of the rack 606, and the surface of the rack 606 fits with the inner wall of the connecting shell 605, when the gas enters the inside of the connecting shell 605, it can push the rack 606 to move.

[0033] like Figures 1 to 9 As shown, the operation method is as follows: S1: The operator places the suction cup 300 on one side of the top of the curbstone, drives the vacuum assembly 200 to extract the air inside the suction cup 300, creating a vacuum state inside the suction cup 300 and adsorbing the curbstone onto the suction cup 300. The operator then uses the control console to control the mobile chassis of the device, so that the entire device drives the suction cup 300 adsorbing the curbstone to move to the predetermined paving path. When the device reaches the paving path, the operator again adjusts the height of the suction cup 300 through the control console to slowly lower the curbstone to the paving position. S2: When the vacuum assembly 200 drives the suction cup 300 to absorb and fix the curb, the exhaust pipe 804 also extracts air from the sealed shell 801, creating a negative pressure space inside the sealed shell 801. The two second sliding rods 802 retract into the sealed shell 801. The second sliding rods 802 drive the mounting block 805, the slider 806, and the positioning plate 808 to contact the surface of the curb, and push the curb toward the middle of the suction cup 300. When the two positioning plates 808 simultaneously contact the surface of the curb, the curb can be fixed in the middle of the suction cup 300, thereby ensuring the accuracy of paving. S3: During the process of lowering and laying the curb, the second ball bearing 508 will contact the top of the already laid curb and squeeze the second ball bearing 508, the second mounting plate 507 and the hinge block 506 upwards. The hinge block 506 will push the two hinge rods 505 to rotate. The rotating hinge rods 505 will pull the two sliding rods 1 403, the first mounting plate 404 and the first ball bearing 405 toward the surface of the already laid curb. When the two first ball bearings 405 simultaneously contact both sides of the already laid curb, the positioning of the curb is completed, ensuring that the curb to be laid is precisely aligned with the already laid curb in both the horizontal and vertical directions. S4: When the curb is laid and the mounting plate 2 507 is away from the curb, the compressed elastic member 1 502 will push the sliding plate 501 and the extrusion rod 602 to move. During the sliding of the extrusion rod 602, the air inside the fixed shell 601 will be pushed through the one-way valve 603 and the air outlet pipe 604 into the connecting shell 605. Then the flowing air will push the rack 606 to move, and the rack 606 will drive the gear 608 to rotate. The gear 608 will drive the cam 609 to rotate, and the rotating cam 609 will contact the surface of the connecting plate 704 and push the knocking block 703 and the connecting plate 704 to move back and forth. During the movement of the knocking block 703, it will knock on the surface of the curb, so that the curb is more tightly combined with the surrounding base materials.

10. A method for automatically laying prefabricated curbstones, using the automatic laying device for prefabricated curbstones according to any one of claims 1 to 9, characterized in that: The method of use is as follows: S1: The operator places the suction cup (300) on one side of the top of the curbstone, drives the vacuum assembly (200) to extract the air inside the suction cup (300), so that the suction cup (300) forms a vacuum state, and the curbstone is adsorbed on the suction cup (300), and then operates the console to control the mobile chassis of the device, so that the entire device drives the suction cup (300) adsorbing the curbstone to move to the predetermined paving path. When the device reaches the paving path, the operator adjusts the height of the suction cup (300) again through the console, so that the curbstone slowly descends to the paving position; S2: When the vacuum assembly (200) drives the suction cup (300) to absorb and fix the curbstone, the exhaust pipe (804) also extracts the air inside the sealing shell (801), so that a negative pressure space is generated inside the sealing shell (801), and the two sliding rods (802) are retracted into the sealing shell (801). The sliding rods (802) drive the mounting block (805), the slider (806) and the positioning plate (808) to contact the surface of the curbstone, and push the curbstone to move toward the middle of the suction cup (300). When the two positioning plates (808) are in contact with the surface of the curbstone at the same time, the curbstone can be fixed in the middle of the suction cup (300), thereby ensuring the accuracy of paving; S3: During the process of the curbstone being lowered and laid, the second ball bearing (508) will contact the top of the already laid curbstone and squeeze the second ball bearing (508), the second mounting plate (507) and the hinge block (506) upwards. The hinge block (506) will push the two hinge rods (505) to rotate. The rotating hinge rods (505) will pull the two sliding rods (403), the first mounting plate (404) and the first ball bearing (405) toward the surface of the already laid curbstone. When the two first ball bearings (405) simultaneously contact both sides of the already laid curbstone, the positioning of the curbstone is completed, ensuring that the curbstone to be laid is precisely aligned with the already laid curbstone in both the horizontal and vertical directions. S4: When the curb is laid and the mounting plate 2 (507) is away from the curb, the compressed elastic member 1 (502) pushes the sliding plate (501) and the extrusion rod (602) to move. During the sliding process of the extrusion rod (602), the air inside the fixed shell (601) is pushed through the one-way valve (603) and the air outlet pipe (604) to enter the inside of the connecting shell (605). Then, the flowing air pushes the rack (606) to move, and the rack (606) drives the gear (608) to rotate. The gear (608) drives the cam (609) to rotate, and the rotating cam (609) contacts the surface of the connecting plate (704) and pushes the knocking block (703) and the connecting plate (704) to move back and forth. During the movement of the knocking block (703), it knocks on the surface of the curb, so that the curb is more tightly combined with the surrounding base material.
