Description

Technical Field

[0001] This invention relates to the field of curbstone paving technology, specifically a single curbstone paving machine. Background Technology

[0002] Curbstones are marker stones placed between the road surface and other structures. Curbstones are generally required between the median strip and the road surface, and between the sidewalk and the road surface in urban roads. They are also often required at the edge of the central median strip, the right edge of the driving lane, or the outer edge of the shoulder of highways.

[0003] Currently, the laying of curb stones mainly relies on manual labor to move and install them. This manual method is not only labor-intensive but also inefficient. Another method involves using large lifting equipment, such as forklifts, to move the curb stones to the side of the road. However, manual alignment and installation are still required after moving the stones. This method using large equipment is more expensive.

[0004] Therefore, this invention proposes a compact single-machine curbstone laying device. Summary of the Invention

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this invention provides a single-machine curbstone laying system, which solves the problems of existing curbstone laying methods that require manual handling and have low laying efficiency.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, the present invention is implemented through the following technical solution: a curbstone paving machine, including a vehicle platform, a U-shaped frame fixedly connected to one end of the vehicle platform, side plates fixedly connected to the bottom ends of both sides of the U-shaped frame, a main shaft passing through and rotatably connected between the two side plates, a traveling wheel fixedly connected to both ends of the main shaft, a cross plate fixedly connected inside the U-shaped frame, and a traveling drive structure for driving the traveling wheels to rotate is provided on the upper surface of the cross plate;

[0009] A first gantry frame is fixedly connected to the side of the vehicle platform away from the U-shaped frame, and the first gantry frame is perpendicular to the vehicle platform. A vertical shaft is rotatably connected through the middle of the top wall of the first gantry frame. A steering wheel is fixedly connected to the bottom end of the vertical shaft, and a control box is fixedly connected to the top end of the vertical shaft. A counterweight structure that can move up and down is provided inside the first gantry frame.

[0010] A second gantry frame is fixedly connected to the side of the U-shaped frame away from the vehicle platform, and the second gantry frame is perpendicular to the U-shaped frame. Two vertical T-shaped guide rails are fixedly connected to the side of the second gantry frame away from the U-shaped frame. T-shaped sliders are slidably connected to the surfaces of the two T-shaped sliders. A lifting plate is fixedly connected to the surfaces of the two T-shaped sliders away from the second gantry frame. A clamping structure for gripping the curb is fixedly installed between the two T-shaped sliders and on the surface of the lifting plate.

[0011] Preferably, the main shaft is located below the horizontal plate, and the walking drive structure includes a motor fixed to the upper surface of the horizontal plate and a second sprocket fixed to the surface of the main shaft. The drive end of the motor is fixedly connected to a first sprocket, and a chain is connected to the surfaces of the first sprocket and the second sprocket.

[0012] Preferably, a handle is fixedly connected to the top of the control box.

[0013] Preferably, the counterweight structure includes two first hydraulic rods fixed to the inner top wall of the first gantry frame, and the bottom telescopic ends of the two first hydraulic rods are jointly fixedly connected to an L-shaped plate. The bottom end of the L-shaped plate is fixedly connected to a support plate for placing curb stones, and a limit plate is fixedly connected to the side of the support plate away from the L-shaped plate.

[0014] Preferably, the L-shaped plate has a through hole in the middle, and the size of the through hole is larger than the vertical axis.

[0015] Preferably, the clamping structure includes two side crossbars fixed to both ends of the lifting plate and a cylinder rotatably connected to the upper surface of the lifting plate. The cylinder is located in the middle of the lifting plate. The ends of the two side crossbars away from the lifting plate are rotatably connected to a clamping plate. The telescopic end of the cylinder is rotatably connected to the top of the clamping plate. The clamping structure also includes an intermediate plate fixed between two T-shaped sliders. The intermediate plate is parallel to the second gantry frame. An electric telescopic rod is fixedly connected to the side of the intermediate plate away from the clamping plate. The telescopic end of the electric telescopic rod passes through the intermediate plate and is fixedly connected to a baffle. The telescopic end of the electric telescopic rod is slidably connected to the intermediate plate.

[0016] Preferably, rubber pads are fixedly connected to the adjacent sides of the baffle and the clamp.

[0017] Preferably, a top plate is fixedly connected to the top of the second gantry frame, and two second hydraulic rods are fixedly connected to both ends of the upper surface of the top plate. The telescopic ends of the bottom of the two second hydraulic rods pass through the top plate and are fixedly connected to the upper surface of the lifting plate.

[0018] Preferably, a hydraulic station and a battery are fixedly connected to the middle of the upper surface of the vehicle panel.

[0019] Working principle: When moving the machine, the motor is first controlled by the control box to rotate. The motor drives the first sprocket to rotate, and through the chain transmission, it drives the second sprocket and the main shaft assembly to rotate, thereby realizing the rotation of the walking wheels and enabling the machine to move. When the machine is moving, the control box can be turned by hand, which drives the vertical shaft to rotate. The vertical shaft then drives the bottom steering wheel to rotate, realizing the steering of the machine when it is moving. When laying curb stones, first move the machine to the curb stone placement area, then position the clamping plate and baffle directly above the curb stone. Then, activate the second hydraulic rod to lower the lifting plate. Once the curb stone is between the clamping plate and baffle, extend the cylinder to rotate the bottom of the clamping plate towards the baffle, using the clamping plate and baffle to clamp and fix the curb stone. After clamping, activate the second hydraulic rod to raise the lifting plate. Since the clamping structure is relatively heavy after holding the curb stone, the first hydraulic rod will raise the pallet simultaneously as the lifting plate raises the clamping structure. This ensures that the curb stone pre-placed on the pallet is balanced with the gripped curb stone, thus maintaining machine balance. Next, move the machine to the side of the road so that the curbstone is aligned with the previously laid curbstone. Then, activate the second hydraulic rod to lower the lifting plate so that the curbstone falls to the ground and aligns with the previous curbstone (similar to the counterweight mentioned above, as the gripped curbstone is lowered, the first hydraulic rod will also lower the support plate to continue to maintain the balance of the machine at both ends). Finally, activate the cylinder to shorten and rotate the clamping plate to release the grip on the curbstone.

[0020] (III) Beneficial Effects

[0021] This invention provides a single machine for laying curb stones. It has the following beneficial effects:

[0022] In use, this invention comprises a platform, a U-shaped frame, wheels, a driving structure, a first gantry, a control box, a handle, a counterweight structure, a second gantry, a lifting plate, a clamping structure, and a second hydraulic rod. The driving structure rotates the wheels, enabling the machine to move. The clamping structure and lifting plate grip and lift the curb stones. After gripping a curb stone, the counterweight structure lifts another curb stone, balancing the machine and preventing tipping. Using this machine for curb stone transport and laying eliminates the need for manual handling, reducing labor intensity and improving laying efficiency. Attached Figure Description

[0029] 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.

[0030] Example:

[0031] like Figure 1 - Figure 5 As shown, this embodiment of the invention provides a single curbstone laying machine, including a platform 1, a U-shaped frame 2 fixedly connected to one end of the platform 1, side plates 3 fixedly connected to the bottom ends of both sides of the U-shaped frame 2, a main shaft 4 passing through and rotatably connected between the two side plates 3, and a traveling wheel 5 fixedly connected to both ends of the main shaft 4. A cross plate 6 is fixedly connected inside the U-shaped frame 2, and a traveling drive structure 7 for driving the traveling wheel 5 to rotate is provided on the upper surface of the cross plate 6; by starting the traveling wheel 5 to rotate through the traveling drive structure 7, the machine can move.

[0032] A first gantry 8 is fixedly connected to the side of the vehicle platform 1 away from the U-shaped frame 2, and the first gantry 8 is perpendicular to the vehicle platform 1. A vertical shaft 9 is rotatably connected through the middle of the top wall of the first gantry 8. A steering wheel 12 is fixedly connected to the bottom end of the vertical shaft 9, and a control box 10 is fixedly connected to the top end of the vertical shaft 9. A counterweight structure 13 that can move up and down is provided inside the first gantry 8. By setting this counterweight structure 13, the two ends of the machine can be kept balanced when the machine grabs the curb stone, and the machine will not produce huge swaying or tilting when it moves.

[0033] A second gantry 14 is fixedly connected to the side of the U-shaped frame 2 away from the vehicle platform 1, and the second gantry 14 is perpendicular to the U-shaped frame 2. Two vertical T-shaped guide rails 15 are fixedly connected to the side of the second gantry 14 away from the U-shaped frame 2. T-shaped sliders 16 are slidably connected to the surfaces of the two T-shaped guide rails 15. A lifting plate 17 is fixedly connected to the surfaces of the two T-shaped sliders 16 away from the second gantry 14. A clamping structure 18 for gripping curb stones is fixedly installed between the two T-shaped sliders 16 and on the surface of the lifting plate 17. The curb stones can be gripped through the clamping structure 18, and the curb stones can be transported and laid in conjunction with the movement of the machine.

[0034] The main shaft 4 is located below the horizontal plate 6. The walking drive structure 7 includes a motor 71 fixed to the upper surface of the horizontal plate 6 and a second sprocket 73 fixed to the surface of the main shaft 4. The drive end of the motor 71 is fixedly connected to a first sprocket 72. The surfaces of the first sprocket 72 and the second sprocket 73 are connected together by a chain 74.

[0035] When motor 71 rotates, it drives the first sprocket 72 to rotate. Then, under the transmission of chain 74, the first sprocket 72 drives the second sprocket 73 to rotate, thereby driving the main shaft 4 to rotate. The traveling wheels 5, which are fixedly connected to both ends of the main shaft 4, will also rotate synchronously, thus realizing the movement of the machine. In this embodiment, motor 71 is a geared motor, which can ensure that the machine's moving speed is not too fast.

[0036] A handle 11 is fixedly connected to the top of the control box 10. The control box 10 can be rotated by the handle 11, which in turn drives the vertical shaft 9 to rotate, and the vertical shaft 9 drives the bottom steering wheel 12 to rotate, so that the machine can turn while walking.

[0037] The counterweight structure 13 includes two first hydraulic rods 131 fixed to the inner top wall of the first gantry frame 8. The bottom telescopic ends of the two first hydraulic rods 131 are fixedly connected to an L-shaped plate 132. The bottom end of the L-shaped plate 132 is fixedly connected to a support plate 133 for placing curb stones. A limit plate is fixedly connected to the side of the support plate 133 away from the L-shaped plate 132.

[0038] In this embodiment, multiple support wheels are rotatably connected to the bottom of the pallet 133. When a curbstone for counterweight is placed on the surface of the pallet 133, the support wheels can support the pallet 133. When the machine moves, the pallet 133 does not contact the ground, and the support wheels can reduce friction and noise.

[0039] When the clamping structure 18 grabs a curbstone and lifts it up, the machine's center of gravity will tilt to the side of the clamping structure 18. In order to ensure the balance of the machine during movement, a counterweight curbstone is placed on the surface of the pallet 133. It can rise and fall synchronously with the curbstone being grabbed. When the clamping structure 18 is not grabbing a curbstone, the support wheel at the bottom of the pallet 133 will contact the ground and play a supporting role. At this time, even if there is a curbstone on the surface of the pallet 133, the machine's center of gravity will not tilt to the side of the counterweight structure 13.

[0040] A through hole 134 is provided in the middle of the L-shaped plate 132, and the size of the through hole 134 is larger than the vertical axis 9.

[0041] The perforation 134 is designed to pass through the vertical shaft 9, so as not to affect the rotation of the vertical shaft 9.

[0042] The clamping structure 18 includes two side crossbars 181 fixed at both ends of the lifting plate 17 and a cylinder 183 rotatably connected to the upper surface of the lifting plate 17. The cylinder 183 is located in the middle of the lifting plate 17. The ends of the two side crossbars 181 away from the lifting plate 17 are rotatably connected to a clamping plate 182. The telescopic end of the cylinder 183 is rotatably connected to the top of the clamping plate 182. The clamping structure 18 also includes an intermediate plate 184 fixed between two T-shaped sliders 16. The intermediate plate 184 is parallel to the second gantry frame 14. An electric telescopic rod 185 is fixedly connected to the side of the intermediate plate 184 away from the clamping plate 182. The telescopic end of the electric telescopic rod 185 passes through the intermediate plate 184 and is fixedly connected to a baffle 186. The telescopic end of the electric telescopic rod 185 is slidably connected to the intermediate plate 184.

[0043] The cylinder 183 drives the clamping plate 182 to rotate, which, together with the baffle 186, can clamp and fix the curbstone, thus achieving the gripping of the curbstone. The electric telescopic rod 185 drives the baffle 186 to move, which can change the initial position of the baffle 186, thereby enabling the gripping of curbstones of different thicknesses.

[0044] Rubber pads are fixedly connected to the adjacent sides of the baffle 186 and the clamp 182.

[0045] The rubber pads can increase the friction between the baffle 186 and the clamp 182 and the curbstone, ensuring clamping stability.

[0046] The top of the second gantry frame 14 is fixedly connected to a top plate 19. Two second hydraulic rods 20 are fixedly connected to both ends of the upper surface of the top plate 19. The telescopic ends of the two second hydraulic rods 20 pass through the top plate 19 and are fixedly connected to the upper surface of the lifting plate 17.

[0047] The lifting plate 17 can be raised and lowered by extending and retracting the second hydraulic rod 20, thereby raising and lowering the clamping structure 18.

[0048] A hydraulic station 21 and a battery 22 are fixedly connected to the middle of the upper surface of the vehicle plate 1. The hydraulic station 21 can provide power to the first hydraulic rod 131 and the second hydraulic rod 20, and the battery 22 can provide electrical energy to the motor 71.

[0049] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
