Description

Technical Field

[0001] This utility model relates to the technical field of road construction equipment, and more specifically to a curbstone laying device for road construction. Background Technology

[0002] A curbstone is a building material used at the edge of a road to separate driveways from sidewalks, green belts, or other areas. It is typically made of concrete, stone, or brick, and is usually rectangular or rectangular in shape. It effectively prevents vehicles from leaving the road, ensuring the safety of pedestrians and vehicles.

[0003] According to patent publication number CN217100011U, published on August 2, 2022, a curbstone transport vehicle is disclosed, including a frame, a lever mechanism, and a clamp. The frame includes two wheels, a main shaft, and a push rod. The wheels are connected to both ends of the main shaft, and the push rod is connected to the main shaft. The lever mechanism includes a support frame and a lifting rod. One end of the support frame is rotatably connected to the middle of the lifting rod, and the other end of the support frame is connected to the main shaft. One end of the lifting rod is connected to the clamp, and the other end is connected to the push rod. The clamp includes a first clamp rod, two second clamp rods, and a limiting sleeve. The two second clamp rods are located outside the first clamp rod. The second clamp rods and the first clamp rod are connected by a rotating shaft. The upper end of the first clamp rod is connected to one end of a lifting ring, and the other end of the lifting ring is connected to the lifting rod. The limiting sleeve is connected to the second clamp rod and is fitted onto the first clamp rod.

[0004] In the prior art, including the aforementioned patent, the current methods for handling curb stones mainly involve manual short-distance handling or using the aforementioned handling vehicles to lift individual curb stones, thereby facilitating subsequent paving of the curb stones. However, such curb stone handling vehicles can only complete the lifting and handling of one curb stone at a time. For the paving of a large number of curb stones, the repeated back-and-forth handling of curb stones requires a lot of physical strength and is prone to problems such as loosening during lifting, resulting in the curb stones falling and breaking.

Multiple casters are fixedly mounted on the bottom of the loading vehicle.

[0007] Preferably, one of the rollers is rotatably mounted on the loading vehicle via a side axle rod. A ratchet is fixedly mounted on the side axle rod, and a support rod is rotatably mounted on the outer wall of the side axle rod. A locking block is hinged on the support rod, and a torsion spring is mounted on the locking block to make the locking block fit against the ratchet.

[0008] Preferably, a semi-circular iron piece is fixedly installed on the outer wall of the baffle on one side of the conveyor belt, and the curved protrusion on the semi-circular iron piece is located on one side of the conveyor belt.

[0009] Preferably, a pad is fixedly installed on one side of the baffle on the loading vehicle, and a buffer rubber plate is fixedly installed on the outer wall of the baffle on the side of the conveyor belt.

[0010] Preferably, the arc-shaped sealing plate fixedly installed on the handrail is movably positioned at the bottom port of the adjustment outlet.

[0021] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0022] like Figure 1-5 As shown, a curbstone laying device for road construction includes a loading vehicle 1 and rollers 11 symmetrically rotatably mounted on it. Multiple support rollers 13 are rotatably mounted between the two rollers 11. Conveyor belts 12 are movably mounted on the rollers 11 and support rollers 13 respectively. A baffle 14 and an adjustment outlet 15 located below the baffle 14 are provided on the conveyor end of the loading vehicle 1 at the conveyor belt 12. Multiple casters 3 are fixedly mounted on the bottom of the loading vehicle 1. By using the loading vehicle 1, multiple curbstones can be placed on the conveyor belt 12 on the support rollers 13. The multiple casters 3 facilitate pushing and pulling the loading vehicle 1 and transporting multiple curbstones, thus achieving batch transport while reducing the problem of curbstones falling off during lifting. Then, by rotating one of the rollers 11, the conveyor belt 12 moves multiple curbstones towards the baffle 14, and they are then discharged sequentially along the adjustment outlet 15, facilitating the large-scale laying of curbstones.

[0023] As a further technical solution provided by this utility model, one of the rollers 11 is rotatably mounted on the loading vehicle 1 via a side shaft rod 18. A ratchet 19 is fixedly mounted on the side shaft rod 18. A support rod 2 is rotatably mounted on the outer wall of the side shaft rod 18, and a locking block 22 is hinged on the support rod 2. A torsion spring 23 is provided on the locking block 22 to make the locking block 22 fit against the ratchet 19.

[0024] Specifically, such as Figure 5As shown, the torsion spring 23 is sleeved on the hinge shaft of the latch 22, and both ends of the latch 22 are fixedly installed on the latch 22 and the guide rod 2, respectively. Since the torsion spring 23 drives the latch 22 to fit against the ratchet 19, and the end of the latch 22 is engaged in the teeth of the ratchet 19, when the guide rod 2 is swung upward, the latch 22 pushes against the teeth of the ratchet 19 and drives the ratchet 19 to rotate, which in turn drives the roller 11 to rotate. Because of the rotation of the roller 11, the conveyor belt 12 is driven by the two rollers 11 and multiple support rollers 13, and drives the curb stone on the conveyor belt 12 to move towards the adjustment outlet 15. Similarly, when the guide rod 2 is swung downward, the guide rod 2 drives the latch 22 to switch between the multiple teeth on the ratchet 19, while the ratchet 19 remains stationary. Then, when the guide rod 2 is swung upward again, the ratchet 19 is driven to rotate again.

[0025] Furthermore, a semi-circular iron piece 16 is fixedly installed on the outer wall of the baffle 14 on one side of the conveyor belt 12, and the curved protrusion on the semi-circular iron piece 16 is located on one side of the conveyor belt 12.

[0026] Specifically, such as Figure 2 As shown, to prevent the curbstone from getting stuck in the top opening of the adjustment outlet 15, when the curbstone moves to the edge of the conveyor belt 12 on the roller 11, the curbstone tilts towards the semi-circular iron piece 16, as shown. Figure 3 As shown, when the conveyor belt 12 continues to drive, it causes the side of the curbstone to slide against the curved protrusion on the semi-circular iron piece 16. The curbstone then gradually maintains a vertical position, and with the continued drive of the conveyor belt 12, the bottom of the curbstone slips off the conveyor belt 12, as shown. Figure 4 As shown, the curbstone then falls into the adjustment outlet 15, thus allowing the curbstone to slide smoothly.

[0027] Furthermore, a pad 17 is fixedly installed on one side of the baffle 14 on the loading vehicle 1, and a buffer rubber plate 4 is fixedly installed on the outer wall of the baffle 14 on one side of the conveyor belt 12.

[0028] Specifically, the pad 17 is used to prevent the bottom of the curb from slipping off the conveyor belt 12 and colliding with the loading vehicle 1, while the buffer rubber plate 4 can reduce the impact between the bottom of the curb and the baffle 14.

[0029] Furthermore, the arc-shaped sealing plate 21 fixedly installed on the handrail 2 is movably positioned at the bottom port of the adjustment outlet 15.

[0030] Specifically, when the handrail 2 is raised, the locking block 22 pushes against the teeth of the ratchet 19, causing the ratchet 19 to rotate, which in turn causes the roller 11 to rotate. Due to the rotation of the roller 11, the conveyor belt 12 is driven by the two rollers 11 and multiple support rollers 13, causing the curb stones on the conveyor belt 12 to move towards the adjustment outlet 15. Further, such as... Figure 5As shown, the arc-shaped sealing plate 21 is located at the bottom end of the handrail 2. When the top of the handrail 2 swings upward, the bottom end of the handrail 2 swings downward to approach and block the adjustment outlet 15. Simultaneously, as the curbstone falls along the adjustment outlet 15 with the transmission of the conveyor belt 12, the arc-shaped sealing plate 21 supports the curbstone within the adjustment outlet 15. Then, when the top of the handrail 2 is driven to swing downward to reset, the handrail 2 drives the locking block 22 to switch between multiple teeth on the ratchet 19, while the ratchet 19 remains stationary. At the same time, the bottom end of the handrail 2 swings upward and releases the blockage of the adjustment outlet 15, and then the curbstone within the adjustment outlet 15 falls again. By using the arc-shaped sealing plate 21 to block and open the adjustment outlet 15, the falling speed of the curbstone can be reduced, preventing the curbstone from falling too fast and generating a large impact force on the ground.

[0031] Furthermore, the arc-shaped sealing plate 21 is made of steel plate.

[0032] Working principle: The loading vehicle 1 allows multiple curb stones to be placed on the conveyor belt 12, which supports rollers 13. Multiple casters 3 facilitate pushing and pulling the loading vehicle 1 and transporting multiple curb stones, achieving batch transport while reducing the risk of curb stones falling off during lifting. When paving is required, the adjustment outlet 15 is moved above the excavated trench, and the support rod 2 is raised. At this time, the locking block 22 pushes against the teeth of the ratchet 19, causing the ratchet 19 to rotate, which in turn drives the rollers 11 to rotate. The rotation of the rollers 11 transmits power to the two rollers 11 and multiple support rollers 13, moving the curb stones on the conveyor belt 12 towards the adjustment outlet 15. Further, as... Figure 5 As shown, when the top of the guide bar 2 swings upward, its bottom swings downward to approach and block the adjustment outlet 15. Simultaneously, as the curbstone falls along the adjustment outlet 15 via the conveyor belt 12, the curved sealing plate 21 supports the curbstone within the adjustment outlet 15. Then, when the top of the guide bar 2 is driven to return to its original position, the guide bar 2 drives the locking block 22 to switch between multiple teeth on the ratchet 19, while the ratchet 19 remains stationary. At the same time, the bottom of the guide bar 2 swings upward and releases the blockage of the adjustment outlet 15. The curbstone within the adjustment outlet 15 then falls again and moves into the excavated construction trench. Similarly, by moving the loading vehicle 1 again and adjusting the position of the adjustment outlet 15, paving can be carried out again along the excavated construction trench. Compared to some kerbstone lifting vehicles, the movement of the loading vehicle 1 combined with the reciprocating push and pull of the guide bar 2 enables batch handling and rapid paving, thereby accelerating the construction process.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
