Description
Technical Field
[0001] This utility model belongs to the field of forklift technology, and in particular relates to a forklift with positioning and clamping function. Background Technology
[0002] Forks are the most commonly used lifting device on a forklift, hence the name forklift. It usually consists of two parts shaped like the letter "L": the horizontal section is used to lift and place goods, while the vertical section provides support.
[0003] The existing fork structure is relatively simple. When picking up cylindrical materials such as steel coils, the materials tend to roll on the forks, resulting in poor stability. Utility Model Content
[0004] To address the technical problem that existing fork structures are relatively simple, and that materials such as steel coils tend to roll on the forks when picking up cylindrical materials, resulting in poor stability, this utility model provides a fork with a positioning and clamping function.
[0005] This utility model is achieved by the following technical solution: a fork with positioning and clamping function, comprising: a base plate for supporting materials; an inner chamber set on the base plate; a fixing plate fixed to the inner wall of the inner chamber; a clamping plate hinged to the fixing plate via a connecting shaft for stabilizing the steel coil material; an adjusting component set in the inner chamber for adjusting the extension state of the clamping plate; and a connecting plate installed on the base plate and connectable to a forklift, the connecting plate being perpendicular to the base plate.
[0006] The above technical solution, by setting a base plate as the foundation for supporting materials and cooperating with a clamping plate, prevents cylindrical materials such as steel coils from rolling directly on the forks when picking them up, thus improving the stability of the material placement. By setting an inner chamber, a fixed plate, a clamping plate, and an adjustment component, the clamping plate can be adjusted to extend its position. When the steel coil is placed on the base plate, the clamping plate can position and clamp the steel coil to prevent it from shaking or shifting during transportation, further improving transportation safety. The connecting plate is installed on the base plate and is set perpendicular to the base plate, which can be easily connected to the forklift, allowing the forks to be smoothly installed on the forklift for operation.
[0007] As a further improvement to the above solution, the adjustment assembly includes a mounting plate fixed inside the inner compartment, a spring mounted on the mounting plate, an adjustment block fixed on the spring, and a support rod hinged to the adjustment block for supporting the card plate. The support rod is hinged to the bottom of the card plate.
[0008] Through the above technical solution, the spring, adjusting block and support rod work together to ensure that when an external force is applied to the clamping plate, the spring will undergo elastic deformation, which will drive the adjusting block to move. In turn, the support rod will push or pull the clamping plate, so that the clamping plate can be flexibly adjusted according to the size and position of the steel coil material, ensuring that the clamping plate can always effectively position, clamp and limit the steel coil material.
[0009] As a further improvement to the above solution, a guide rod with a movable through spring is installed on the adjusting block to limit the spring's extension and retraction path. A connecting rope extending to the outside of the inner compartment is installed on the guide rod, and a pull ring for providing an operating grip point is fixed on the connecting rope.
[0010] The above technical solution, by setting a guide rod that passes through the spring, can limit the extension and retraction path of the spring. When the spring is extending or retracting, the guide rod can play a guiding role, preventing the spring from deviating or twisting during the extension and retraction process. The design of the connecting rope provides the operator with the possibility of remotely operating the adjustment block. The operator does not need to directly contact the adjustment block, but only needs to pull the pull ring to drive the guide rod with the help of the connecting rope, thereby indirectly applying external force to the adjustment block and realizing the adjustment of the plate.
[0011] As a further improvement to the above solution, plastic films are provided on both sides of the inner compartment to seal the inner compartment. The plastic films are connected to the bottom of the card plate. A guide frame for stabilizing the connecting rope is fixed inside the inner compartment, and the connecting rope moves through the guide frame.
[0012] The above technical solution, by setting plastic films on both sides of the inner compartment for sealing, can seal the inner compartment and prevent external dust, debris, etc. from entering the inner compartment and affecting the normal operation of internal components such as the adjustment component. When the clamping plate moves, the plastic film expands and contracts accordingly, without hindering the movement of the clamping plate. The guide frame can guide and support the connecting rope, so that the connecting rope maintains a stable movement trajectory during the pulling process, avoiding the connecting rope from shaking, tangling, or interfering with other components. This ensures that the operation of adjusting the adjustment block by pulling the connecting rope through the pull ring can be carried out smoothly, improving the reliability and stability of the adjustment component.
[0013] As a further improvement to the above solution, a support block for supporting the pallet is fixed inside the inner compartment, and a shock-absorbing pad for vibration reduction and noise reduction is installed on the top of the support block. The shock-absorbing pad is made of rubber.
[0014] Through the above technical solution, the support block is used to support the pallet, which provides a reliable point of force for the pallet. This ensures that the pallet can maintain a stable support state when bearing the weight of the steel coil and various external forces during transportation, preventing the pallet from deforming or being damaged due to uneven force or insufficient support. This ensures that the positioning and clamping function of the forks on the steel coil is normal. The rubber shock-absorbing pad installed on the top of the support block has good shock absorption and noise reduction performance. During the transportation process of the forks, when encountering bumps or vibrations, the shock-absorbing pad can absorb and buffer the impact force between the pallet and the support block, reduce the noise caused by vibration, and reduce the impact on the surrounding environment.
[0015] As a further improvement to the above scheme, a guide plate for assisting in the feeding of steel coils is provided on the side of the base plate away from the connecting plate, a guide slope is provided on one side of the guide plate, and an anti-slip pad for increasing friction is installed on the top of the base plate.
[0016] Through the above technical solution, the guide plate plays a guiding role, enabling the steel coil to roll smoothly along the guide slope onto the bottom plate, reducing the difficulty of loading the steel coil, improving the loading efficiency, reducing the workload of operators, and the anti-slip mat can increase the friction between the steel coil and the bottom plate, ensuring that the steel coil always maintains a stable position, improving the safety and stability of transportation, and reducing the risk of safety accidents and cargo damage that may be caused by the slippage of the steel coil.
[0017] As a further improvement to the above solution, the bottom of the inner compartment is provided with a slide groove, in which a slider connected to the adjusting block is slidably installed. The slider is inlaid with balls that contact the inner wall of the slide groove to reduce friction. The slide groove and the slider are used to limit the movement path of the adjusting block.
[0018] Through the above technical solution, the sliding groove and the slider work together to precisely limit the movement path of the adjusting block, ensuring that the adjusting block can only move in the predetermined direction, avoiding the adjusting block from deviating or shaking during the movement, so that the clamping plate can accurately position and clamp the steel coil material, improving the adaptability and stability of the forks to cylindrical materials.
[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0020] This utility model, through the cooperation of a clamping plate and an adjustment component, can flexibly adjust according to the size and position of the steel coil, effectively positioning, clamping, and limiting the steel coil material, thus improving transportation safety. With the addition of a connecting rope and a pull ring, operators can remotely operate the adjustment block without direct contact; the clamping plate can be adjusted by pulling the pull ring. A guide rod limits the spring's extension and retraction path, a guide frame stabilizes the connecting rope, and a sliding groove and slider cooperate to limit the movement path of the adjustment block, ensuring stable operation of all components and improving the fork's adaptability and stability to cylindrical materials. A plastic film seals the inner chamber to prevent dust and debris from entering. A guide plate assists in steel coil loading, and anti-slip pads increase friction, improving loading efficiency and transportation safety. Support blocks and shock-absorbing pads support the clamping plate, reducing vibration and noise. Attached Figure Description

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0027] Example:
[0028] Please combine Figure 1-4The forklift with positioning and clamping function in this embodiment includes: a base plate 1 for supporting materials; an inner chamber 2 disposed on the base plate 1; a fixing plate 3 fixed to the inner wall of the inner chamber 2; a clamping plate 5 hinged to the fixing plate 3 via a connecting shaft 4 for stabilizing the steel coil material; an adjustment assembly disposed within the inner chamber 2 for adjusting the extension state of the clamping plate 5; and a connecting plate 16 mounted on the base plate 1 and connectable to a forklift, wherein the connecting plate 16 is perpendicular to the base plate 1, and the base plate 1 serves as the base for supporting materials in conjunction with the clamping plate 5. When picking up cylindrical materials such as steel coils, the material can be prevented from rolling directly on the forks, improving the stability of the material placement. By setting up the inner chamber 2, the fixed plate 3, the clamping plate 5, and the adjustment component, the clamping plate 5 can be adjusted to extend its state through the adjustment component. When the steel coil material is placed on the base plate 1, the clamping plate 5 can position and clamp the steel coil material to prevent it from shaking or shifting during transportation, further improving transportation safety. The connecting plate 16 is installed on the base plate 1 and is set perpendicular to the base plate 1, which can be easily connected to the forklift, so that the forks can be smoothly installed on the forklift for operation.
[0029] The adjustment assembly includes a mounting plate 7 fixed inside the inner chamber 2, a spring 8 mounted on the mounting plate 7, an adjustment block 9 fixed on the spring 8, and a support rod 10 hinged to the adjustment block 9 for supporting the clamping plate 5. The support rod 10 is hinged to the bottom of the clamping plate 5. Through the coordinated action of the mounting plate 7, spring 8, adjustment block 9, and support rod 10, when an external force is applied to the clamping plate 5, the spring 8 will undergo elastic deformation, causing the adjustment block 9 to move. In turn, the support rod 10 pushes or pulls the clamping plate 5, allowing the clamping plate 5 to be flexibly adjusted according to the size and position of the steel coil material, ensuring that the clamping plate 5 can always effectively position, clamp, and limit the steel coil material.
[0030] The adjusting block 9 is equipped with a guide rod 11 that movably passes through the spring 8 to limit the extension and retraction path of the spring 8. A connecting rope 20 extending to the outside of the inner compartment 2 is installed on the guide rod 11. A pull ring 21 for providing an operating grip point is fixed on the connecting rope 20. By setting the guide rod 11 that movably passes through the spring 8, the extension and retraction path of the spring 8 can be limited. When the spring 8 is extending and retracting, the guide rod 11 can play a guiding role to prevent the spring 8 from deviating or twisting during the extension and retraction process. The design of the connecting rope 20 provides the operator with the possibility of remotely operating the adjusting block 9. The operator does not need to directly contact the adjusting block 9. He only needs to pull the pull ring 21 to drive the guide rod 11 with the help of the connecting rope 20, thereby indirectly applying external force to the adjusting block 9 and realizing the adjustment of the clamping plate 5.
[0031] Both sides of the inner chamber 2 are provided with plastic films 6 for sealing the inner chamber 2. The plastic films 6 are connected to the bottom of the card plate 5. A guide frame 19 for stabilizing the connecting rope 20 is fixed inside the inner chamber 2. The connecting rope 20 moves through the guide frame 19. By setting plastic films 6 on both sides of the inner chamber 2 for sealing, the inner chamber 2 can be sealed to prevent external dust, debris and other objects from entering the inner chamber 2 and affecting the normal operation of internal components such as the adjustment component. When the card plate 5 is adjusted and moved, the plastic films 6 expand and contract accordingly without hindering the movement of the card plate 5. The guide frame 19 can guide and support the connecting rope 20, so that the connecting rope 20 maintains a stable movement trajectory during the pulling process, avoiding the connecting rope 20 from shaking, tangling or interfering with other components. This ensures that the operation of adjusting the adjustment block 9 by pulling the connecting rope 20 through the pull ring 21 can be carried out smoothly, improving the reliability and stability of the adjustment component.
[0032] The inner compartment 2 is fixed with a support block 12 for supporting the pallet 5. The top of the support block 12 is equipped with a shock-absorbing pad 13 for vibration reduction and noise reduction. The shock-absorbing pad 13 is made of rubber. The support block 12 supports the pallet 5, which provides a reliable point of force for the pallet 5. This ensures that the pallet 5 can maintain a stable support state when bearing the weight of the steel coil material and various external forces during transportation. It prevents the pallet 5 from deforming or being damaged due to uneven force or insufficient support, thereby ensuring that the positioning and clamping function of the forks on the steel coil material is normal. The rubber shock-absorbing pad 13 installed on the top of the support block 12 has good vibration reduction and noise reduction performance. During the transportation process of the forks, when encountering bumps, vibrations, etc., the shock-absorbing pad 13 can absorb and buffer the impact force between the pallet 5 and the support block 12, reduce the noise generated by vibration, and reduce the impact on the surrounding environment.
[0033] The bottom plate 1 is provided with a guide plate 14 for assisting in loading steel coils on the side away from the connecting plate 16. A guide slope is provided on one side of the guide plate 14. An anti-slip pad 15 for increasing friction is installed on the top of the bottom plate 1. The guide plate 14 plays a guiding role, allowing the steel coil to roll smoothly onto the bottom plate 1 along the guide slope, reducing the difficulty of loading steel coils, improving loading efficiency, and reducing the workload of operators. The anti-slip pad 15 can increase the friction between the steel coil and the bottom plate 1, ensuring that the steel coil always maintains a stable position, improving the safety and stability of transportation, and reducing the risk of safety accidents and cargo damage that may be caused by the slippage of the steel coil.
[0034] The bottom of the inner compartment 2 is provided with a sliding groove, in which a slider 17 connected to the adjusting block 9 is slidably installed. The slider 17 is embedded with balls 18 that contact the inner wall of the sliding groove to reduce friction. The sliding groove and the slider 17 are used to limit the movement path of the adjusting block 9. The sliding groove and the slider 17 work together to precisely limit the movement path of the adjusting block 9, ensuring that the adjusting block 9 can only move in a predetermined direction, avoiding the adjusting block 9 from deviating or shaking during movement. This allows the clamping plate 5 to accurately position and clamp the steel coil material, improving the adaptability and stability of the forks to cylindrical materials.
[0035] The implementation principle of a forklift with positioning and clamping function in this application embodiment is as follows: When in use, the forklift picks up the steel coil, and the steel coil moves to the base plate 1 through the guide ramp. During the process, the clamping plate 5 is squeezed and the spring 8 is in a compressed state. When the steel coil rolls away from the clamping plate 5, the spring 8 rebounds. At this time, the angle of the clamping plate 5 changes and extends out of the inner chamber 2 to contact the steel coil. Together with the connecting plate 16, it plays the role of clamping and stabilizing the steel coil. When it is necessary to unload the material, the operator pulls the pull ring 21 to retract the spring 8. At this time, the clamping plate 5 enters the inner chamber 2, the limiting structure of the steel coil is unlocked, and the steel coil can be rolled to complete the unloading. During the process, the support block 12 supports the clamping plate 5 to effectively prevent it from retracting too much and causing the steel coil to get stuck in the inner chamber 2.
[0036] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
