Abstract
Description
Technical Field
[0001] This utility model relates to the field of handling tools, specifically to a curbstone handling cart. Background Technology
[0002] Curbstone handling trolleys are often designed to combine leverage principles with mechanical clamping. A rotatable hook at the front of the trolley, along with cross-clamping rods, allows for the lifting and secure transport of curbstones. This design utilizes leverage to reduce manual labor while enhancing safety through mechanical clamping.
[0003] The lack of a support device in existing curbstone transport carts exposes significant defects in terms of operational efficiency, safety, equipment wear and tear, and applicability. Lever-type carts rely on the lever principle to save effort, but if the curbstone is not stably supported, it is easy for the stone to slip due to centrifugal force when turning, requiring the operator to exert extra force to control it, which limits its use in narrow spaces or complex road conditions. When the cart is moved, the curbstone may shake and hit the transport cart. The weight of the curbstone acts directly on the support rod, which can lead to metal fatigue or deformation or even breakage in the long run, shortening the life of the cart. Utility Model Content
[0004] The purpose of this utility model is to provide a curbstone transport cart that can evenly distribute the weight of the curbstone to the cart structure using a support device, reducing the additional fixing force required by the operator. The support device acts as an intermediate layer between the curbstone and the cart lever structure, preventing the metal lever from directly bearing the pressure of the stone, reducing the risk of metal fatigue and deformation. The support device keeps the curbstone stable when turning or passing over bumpy road slopes, preventing damage to the transport cart caused by the curbstone shaking, and reducing the frequency of force adjustment by the operator, thus solving the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a curbstone transport cart, characterized in that it comprises: a fixed rod, a support rod, a crossbar, a supporting device, a moving device, a hook, a clamp, two moving wheels, two first reinforcing rods, a second reinforcing rod, and a sleeve. The supporting device includes a positioning plate, two supporting plates, and a through hole. The through hole is formed on the positioning plate. The positioning plate is slidably mounted on the support rod. Both supporting plates are hinged to the positioning plate. The moving device comprises: a winch, a fixed pulley, and a wire rope. The winch is fixedly mounted on the crossbar. The fixed pulley is fixedly mounted on the crossbar. One end of the wire rope is fixedly mounted on the positioning plate. The other end of the wire rope is wound around the winch. The wire rope is arranged on the fixed pulley.
[0006] Furthermore, the feature is that: the support rod is fixedly installed on the fixed rod, the two first reinforcing rods are fixedly installed on both sides of the support rod, and the bottom ends of the two first reinforcing rods are fixedly connected to the fixed rod.
[0007] Furthermore, the crossbar is fixedly installed inside the sleeve by bolts, and the sleeve is fixedly installed at the top of the support rod.
[0008] Furthermore, the feature is that the second reinforcing rod is fixedly installed on the support rod, and the top end of the second reinforcing rod is fixedly connected to the sleeve.
[0009] Furthermore, the feature is that the hook is fixedly installed on the crossbar.
[0010] Furthermore, the feature is that the clamp is hung on the hook.
[0011] Furthermore, the feature is that both of the movable wheels are rotatably mounted on the fixed rod.
[0012] In summary, due to the adoption of the above-mentioned technologies, the beneficial effects of this utility model are:
[0013] This utility model, by setting up a support device, can evenly distribute the weight of the curbstone to the cart structure using the support plate, reducing the additional fixing force required by the operator. The support device, as an intermediate layer between the curbstone and the cart lever structure, avoids the metal lever directly bearing the pressure of the stone, reducing the risk of metal fatigue and deformation.
[0014] This invention utilizes a moving device and the characteristic of a winch's small gear driving a large gear to amplify torque and reduce the physical burden on workers. When the winch stops working, the ratchet and gear automatically engage, forming a mechanical locking structure. In scenarios involving the movement of curb stones, if it is necessary to temporarily suspend heavy objects (such as adjusting the position of a cart or waiting for other workers to assist), the winch can ensure that the heavy objects do not slip, preventing injury to personnel or damage to equipment.

[0020] This utility model provides, for example Figure 1-3A curbstone transport cart is shown, characterized in that it includes: a fixed rod 1, a support rod 2, a crossbar 3, a supporting device 4, a moving device 5, a hook 6, a clamp 7, two moving wheels 8, two first reinforcing rods 9, a second reinforcing rod 10, and a sleeve 11. The supporting device 4 includes a positioning plate 401, two supporting plates 402, and a through hole 403. The through hole 403 is formed on the positioning plate 401. The positioning plate 401 is slidably mounted on the support rod 2. The two supporting plates 402 are hinged to the positioning plate 401. The moving device 5 includes: a winch 501, a fixed pulley 502, and a wire rope 503. The winch 501 is fixedly mounted on the crossbar 3, the fixed pulley 502 is fixedly mounted on the crossbar 3, one end of the wire rope 503 is fixedly mounted on the positioning plate 401, and the other end of the wire rope 503 is wound around the winch 501. The wire rope 503 is mounted on the fixed pulley 502. The surfaces of the two support plates 402 are covered with rubber pads, anti-slip coatings, or granular textures, significantly increasing the friction with the curbstone and maintaining stability even on wet or bumpy roads. The two support plates 402 have arc-shaped grooves for quick alignment with the curbstone and fixation, reducing manual adjustments. The winch 501 is a bidirectional winch that supports forward and reverse adjustment, allowing flexible control of the lifting or lowering of heavy objects to adapt to different operational needs. It has a built-in brake ratchet and a load-bearing ratchet. When the wire rope is under force and the drum is stationary, the ratchet automatically engages to prevent the heavy object from slipping. The winch 501 is model SDL1800. The hinge is a damping hinge with a built-in mechanical locking mechanism, which can fix the support plate 402 at any angle to prevent displacement due to gravity or external forces.

The whole device is equivalent to a lever to clamp and lift the curbstone. Then, rotate the winch 501 to control the wire rope 503 to move upward. The upward movement of the wire rope 503 drives the positioning plate 401 and the support plate 402 to move until the support plate 402 lifts the bottom of the curbstone. After that, when the curbstone transport trolley is moved to the appropriate position, lift the crossbar 3, and at the same time rotate the winch 501 to control the wire rope 503 to move downward. The positioning plate 401 and the support plate 402 move downward. The support plate 402 slowly moves away from the curbstone, and the clamp 7 opens its arms under the action of gravity, placing the curbstone in the designated position.
