Clamps and lifting devices for curb stones

Abstract

This utility model relates to the field of engineering decoration tools, specifically to a curbstone clamp and lifting device. The curbstone clamp includes a clamping component, a handle, a disassembly component, and an abutment component. The clamping component includes a support rod and clamping bodies located on both sides of the support rod. The support rod connects the two clamping bodies, which clamp the curbstone. The handle is vertically connected to the support rod. The disassembly component is rotatably connected to the support rod and the clamping bodies. Pulling the disassembly component causes the clamping bodies to rotate and release the curbstone, preventing inefficient disassembly due to excessive tightness between the clamping bodies and the curbstone. The abutment component connects to the clamping bodies and abuts against the disassembly component, limiting the rotation angle of the disassembly component. This prevents the disassembly component from rotating under external force when the curbstone is not clamped, thus changing the shape of the clamping bodies and affecting the clamping effect on the curbstone.

Description

Technical Field

[0001] This utility model relates to the field of engineering decoration tools, specifically to a clamp and lifting device for curb stones. Background Technology

[0002] Curbstones are boundary stones at the edge of road surfaces, serving as the dividing line between highways and sidewalks to protect the safety of pedestrians and vehicles. Curbstones often settle or become damaged due to factors such as compacted backfill or vehicle impacts. Therefore, whether installing or repairing curbstones, they require handling and adjustment.

[0003] Because curb stones are typically smooth rectangular prisms, they are heavy and bulky, making direct handling by personnel difficult. Existing curb stone clamps use clips or wires to hold the curb stone in place, thus moving it. However, when the curb stone is placed in a specific position, the contact gap between adjacent curb stones is small, making it difficult to easily separate the clamp from the curb stone. A certain distance must be maintained during installation, and other devices must be used to move the curb stone to the designated position later, resulting in low construction efficiency. Utility Model Content

[0004] This utility model was made to solve the above-mentioned technical problems. Its purpose is to provide a clamp for curb stones. By setting a disassembly component, the curb stone can be quickly detached from the clamp after being transported to a designated position, thereby improving construction efficiency.

[0005] To achieve the above objectives, this utility model provides a curbstone clamp, including a clamping member comprising a support rod and clamping bodies disposed on both sides of the support rod; a handle vertically connected to the support rod; a disassembly member rotatably connected to the support rod and the clamping bodies, capable of rotating the clamping bodies to release the curbstone; and an abutment member connected to the clamping bodies and abutting against the disassembly member, limiting the rotation angle of the disassembly member.

[0006] Preferably, the clamping body includes a clamping arm and two side clamping arms, with the two ends of the two side clamping arms respectively connected to the clamping arm and the support rod, and the disassembly component connected to the clamping arm.

[0007] Preferably, the disassembly component is connected to the middle of the clamping arm and the support rod.

[0008] Preferably, an anti-slip pad is provided at the connection between the two side clamping arms and the clamping arm.

[0009] Preferably, the anti-slip pad is a rubber pad.

[0010] Preferably, there are two disassembly components, which are respectively connected to the two clamping bodies.

[0011] Preferably, the abutment member is a torsion spring.

[0012] Preferably, the handle is rotatably connected to the support rod, and the handle includes a handle body and a handle sleeve, with the handle sleeve fitted onto the handle body.

[0013] Preferably, the gloves are made of rubber tubing or fiberglass tubing.

[0014] This utility model provides a lifting device for curb stones, including a clamp for curb stones as described above and a winch, wherein the handle further includes a lifting ring, and the lifting ring is connected to the winch.

[0015] This utility model provides a curbstone clamp, including a clamping component, a handle, a disassembly component, and an abutment component. The clamping component includes a support rod and clamping bodies located on both sides of the support rod. The support rod connects the two clamping bodies, which clamp the curbstone. The handle is vertically connected to the support rod, allowing the curbstone to be lifted directly. The disassembly component is rotatably connected to the support rod and the clamping bodies. Pulling the disassembly component causes the clamping bodies to rotate, releasing the curbstone. This prevents the clamping bodies from being too tightly fitted to the curbstone, which would reduce efficiency during disassembly. The abutment component is connected to the clamping bodies and abuts against the disassembly component, limiting the rotation angle of the disassembly component. This prevents the disassembly component from rotating under external force when the curbstone is not clamped, thus changing the shape of the clamping body and affecting the clamping effect on the curbstone.

[0022] Curbstones are boundary stones at the edges of road surfaces, serving as the dividing line between the road and the sidewalk, and are used to protect the safety of pedestrians and vehicles. Curbstones vary in size depending on the needs, and lighter curbstones can be carried manually, while heavier curbstones require the use of transport vehicles and winches for transport. Furthermore, in practice, curbstones placed according to road design often settle or become damaged due to factors such as insufficient backfilling during placement or collisions with vehicles. For road planning and aesthetic purposes, it is necessary to modify or replace curbstones, thus requiring their movement and adjustment.

[0023] This utility model discloses a clamp for curb stones; please refer to [reference needed]. Figures 1 to 3In some embodiments, the curbstone clamp includes a clamping component 1, a handle 2, a disassembly component 3, and an abutment component 4. The clamping component 1 includes a support rod 11 and clamping bodies 12 disposed on both sides of the support rod 11. The support rod 11 connects the two clamping bodies 12, which clamp the curbstone. The handle 2 is vertically connected to the support rod 11, allowing the curbstone to be lifted directly. The disassembly component 3 is rotatably connected to the support rod 11 and the clamping bodies 12. Pulling the disassembly component 3 causes the clamping bodies 12 to rotate and release the curbstone, preventing the clamping bodies 12 from clamping the curbstone too tightly, which would otherwise result in low efficiency during disassembly. The abutting part 4 is connected to the clamping body 12 and abuts against the disassembly part 3, limiting the rotation angle of the disassembly part 3. This prevents the disassembly part 3 from rotating under the action of external force when the curbstone is not clamped, thereby changing the shape of the clamping body 12 and affecting the clamping effect of the clamp on the curbstone.

[0024] Understandably, the typical size of large curb stones is 1000×300×15mm. To ensure the long-term usability of the curb stone clamp, the handle 2 and the clamping part 1 are made of No. 8 iron wire with a diameter of 4 mm. The included angle between the two clamping bodies 12 is between 140 and 160 degrees, with 150 degrees being optimal. This ensures the overall stability of the clamp and prevents damage to the clamp during transport due to the excessive weight of the curb stone, thus affecting the overall efficiency of curb stone transport.

[0025] To ensure the stability of the clamping body 12 in clamping the curbstone, in some embodiments, the clamping body 12 includes a clamping arm 13 and two side clamping arms 14. The two ends of the two side clamping arms 14 are respectively connected to the clamping arm 13 and the support rod 11. The disassembly piece 3 is connected to the clamping arm 13. The side clamping arms 14 and the clamping arm 13 make contact with the surface of the curbstone, thereby ensuring the clamping effect of the curbstone and preventing the curbstone from falling out of the clamp and causing damage to the curbstone.

[0026] Furthermore, in order to ensure that the disassembly component 3 can be stably connected to the clamping body 12 and can provide similar forces to the side clamping arms 14 and clamping arms 13 when the clamping body 12 is detached from the curb, in some embodiments, the disassembly component 3 is connected to the middle of the clamping arm 13 and the support rod 11. When it is necessary to use the disassembly component 3 to pull the clamp to detach from the curb, the operator directly pulls the disassembly component 3 to transmit the pulling force to the clamping arm 13 and the support rod 11, causing the clamping arm 13 to move upward until it is detached from the curb. The pulling force is located in the middle, so that the force on both sides of the point of action is the same, thereby avoiding the clamping body 12 being subjected to different forces at both ends, which would cause the clamping body 12 to deform and affect the subsequent clamping effect of the clamp on the curb.

[0027] Understandably, to prevent the gripping body 12 from affecting the gripping effect of the curbstone due to the excessive smoothness of the curbstone surface, in some embodiments, anti-slip pads 5 are provided at the connection between the two side clamping arms 14 and the clamping arm 13. On the one hand, this increases the friction between the curbstone edges and the gripping body 12, preventing the curbstone from falling out of the gripping body 12; on the other hand, by providing anti-slip pads 5 at the edges, the edges of the curbstone are also protected from being broken by external impacts during transportation, which would require repair or replacement of the curbstone, thus affecting the paving efficiency of the curbstone.

[0028] Understandably, in some embodiments, the anti-slip mat 5 is a rubber mat that can fit tightly against the curbstone, reduce the contact gap between the curbstone and the clamping body 12, improve stability, and prevent the curbstone from slipping off the clamping body 12. In addition, the rubber mat is easier to clean. When the clamping body 12 and the anti-slip mat 5 are contaminated with dirt and affect the clamping of the curbstone, they can be washed clean with water, making it more suitable for use during road construction.

[0029] Similarly, in order to avoid the inability to completely separate the clamp from the curbstone when only one end of the clamping body 12 is pulled when separating the clamp and the curbstone, in some embodiments, two disassembly parts 3 are provided, which are respectively connected to the two clamping bodies 12. After the curbstone is transported to the corresponding position, the two disassembly parts 3 can be pulled at the same time, so that the clamping bodies 12 on both sides of the support rod 11 are simultaneously disengaged from the curbstone, thus completing the disassembly of the curbstone.

[0030] To ensure that the disassembly component 3 can automatically return to its original position after removing the curbstone from the clamping body 12, in some embodiments, the abutment component 4 is a torsion spring. When the operator uses the clamp to hold the curbstone, part of the curbstone contacts the disassembly component 3, exerting a certain force on the disassembly component 3 and the abutment component. After the curbstone is transported to the designated location, when the operator pulls the disassembly component 3 to remove the curbstone from the clamping body 12, the abutment component 4 receives a pulling force in the opposite direction, thereby causing the curbstone to detach from the clamping body 12. At the same time, the disassembly component 3 can return to its original position under the reset action of the torsion spring, waiting for the clamping body 12 to clamp the curbstone again. This avoids the disassembly component 3 rotating too much under the action of gravity when the clamp as a whole is not in use, which would affect the disassembly effect of the disassembly component 3 on the curbstone.

[0031] Furthermore, to facilitate operators in using clamps to transport curb stones, in some embodiments, the handle 2 is rotatably connected to the support rod 11. The handle 2 is used to lift the curb stone and the clamping body 12 to deliver the curb stone to the corresponding position. The handle 2 includes a handle 2 body and a glove (not shown). The glove is fitted onto the handle 2 body. In actual use, to save costs and for ease of acquisition, the handle 2 body is usually made of wire. The wire is relatively thin and not easy for operators to lift directly. Therefore, the glove is fitted onto the handle 2 body to increase the contact area of ​​the hand gripping the handle 2, thereby protecting the operator's hands and preventing the handle 2 body from cutting the operator's hands when the wire is thin and the curb stone is heavy.

[0032] The gloves can be made of rubber tubing or fiberglass tubing, depending on the actual needs. Fiberglass tubing is harder than rubber tubing, which further increases the contact area for the hand when transporting larger and heavier curb stones, thus preventing hand injuries to operators when transporting curb stones.

[0033] This utility model provides a lifting device for curb stones, including any of the above-mentioned curb stone clamps and a winch (not shown). In some embodiments, due to the large weight of large curb stones, it is difficult to handle them manually, and the handling efficiency is extremely low. By using a winch to drive the clamps to rise and fall, and using a transport vehicle to move them, the curb stones can be transported to a designated location. The handle 2 also includes a lifting ring (not shown), which is connected to the winch. When it is necessary to transport the curb stone to a designated location, the winch hooks the lifting ring on the handle 2 and drives the clamps to pull up the curb stone. The transport vehicle then moves the curb stone to the corresponding position, and the winch works again to lower the curb stone, completing the transportation of the curb stone.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
