Abstract
Description
Technical Field
[0001] This utility model relates to the field of forklift technology, and more specifically, to a forklift lifting clamp. Background Technology
[0002] Forklifts are commonly used material handling equipment and often need to be used in conjunction with lifting tools to complete various workpiece lifting operations. Currently, traditional forklift lifting tools are usually connected to the forklift forks through a simple frame structure, and the connection method mostly relies on the friction between the forks and the frame or bolt fastening.
[0003] However, this type of connection has obvious drawbacks: when faced with forklift forks of different thicknesses, the clamp size of the frame is fixed, making it difficult to achieve adaptive fastening and easily leading to loose connections. This not only affects the stability of lifting operations but may also cause safety hazards. If bolt fastening is used, the operation process is cumbersome, requiring repeated disassembly and adjustment of the bolts, which greatly reduces the efficiency of the operation. Utility Model Content
[0004] The purpose of this utility model is to solve the problems mentioned in the background art above, and then to propose a forklift lifting clamp.
[0005] The technical solution adopted by this utility model to solve its technical problem is:
[0006] A forklift lifting clamp includes a lifting frame and lifting clamps. The lifting frame includes a lifting beam with two symmetrical sockets for connecting forklift forks. The lifting beam also has a drive assembly with two output ends, each connected to a top plate. The top plate is located inside the socket and can be moved closer to or away from the top surface inside the socket by operating the drive assembly. A U-shaped frame for mounting the lifting clamps is also installed on the lifting beam.
[0007] Furthermore, the above-mentioned solution includes a screw rod vertically mounted on the suspension beam, a crank handle connected to the top of the screw rod, and a connecting plate rotatably connected to the bottom of the screw rod. The connecting plate is located below the suspension beam and has two vertically symmetrically mounted sliding rods on the connecting plate. The sliding rods pass through the suspension beam and extend into the socket to connect with the top plate.
[0008] Furthermore, the above solution includes a spring sleeved on the outside of the sliding rod, with the spring positioned between the connecting plate and the lifting beam.
[0009] Furthermore, the above solution includes a spring sleeved on the outside of the screw, with the spring positioned between the connecting plate and the lifting beam.
[0010] Furthermore, the above solution includes a rubber block on the top of the socket for contact with the forklift forks.
[0011] Furthermore, the above solution involves connecting the U-shaped frame and the lifting clamp via an adjustment assembly, enabling the lifting clamp to perform horizontal movement and rotation.
[0012] Furthermore, the above solution includes a sliding sleeve that is horizontally slidably fitted onto a U-shaped frame. The sliding sleeve is provided with an inner port seat, and the bottom surface of the inner port seat is provided with a through hole. The inner port seat is provided with a limiting seat whose size is smaller than its inner cavity and larger than the through hole. The limiting seat is provided with an insertion rod, which passes through the through hole and extends to the bottom of the inner port seat to connect with the lifting clamp.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] This invention features a top plate controlled by a drive assembly within the socket of the hoisting frame, allowing for flexible adjustment of the clamping jaws. When forklift forks are inserted into the socket, operating the drive assembly moves the top plate closer to or further away from the socket's top surface, thus tightly clamping forks of varying thicknesses. This effectively solves the problems of fixed clamping jaw sizes and poor adaptability in traditional hoisting frames, significantly improving the equipment's versatility.
[0015] Furthermore, by utilizing the drive assembly to tighten and secure the top plate against the forks, a rigid connection is formed, significantly enhancing the connection strength between the lifting frame and the forklift forks. Compared to traditional connections relying on friction or bolts, this structure effectively prevents loosening or displacement during lifting, reducing the risk of workpiece falling and providing reliable assurance for operational safety.
[0016] Furthermore, during installation, simply insert the forks into the socket and tighten them using the drive assembly; during disassembly, simply reverse the operation of the drive assembly to release the fixation, eliminating the need for a cumbersome bolt removal process. The entire operation is simple and quick, significantly reducing the time required for equipment installation and disassembly, and helping to improve the overall efficiency of lifting operations.

Detailed Implementation
[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The present utility model will be further described with reference to the accompanying drawings and embodiments:
[0023] A forklift lifting clamp, see attached. Figure 1 and attached Figure 2 As shown, it includes a hoisting fixing frame 1 and a hoisting clamp 2. The hoisting clamp 2 is a commonly used hoisting structure in the prior art, which uses the workpiece's own weight to achieve the purpose of fastening and clamping. This application will not elaborate on this. The improvement of this application lies in the hoisting fixing frame 1.
[0024] In this application, the lifting and fixing frame 1 includes a lifting beam 11. Two sockets 12 for connecting forklift forks are symmetrically arranged on the lifting beam 11. A set of drive components 13 is also provided on the lifting beam 11. Each drive component 13 has two output ends, and each output end is connected to a top plate 14. The top plate 14 is located inside the socket 12 and can be moved closer to or further away from the top surface inside the socket 12 by operating the drive component 13, forming an adjustable clamping opening to complete the clamping and fixing operation of the forklift forks. In addition, a U-shaped frame 15 for installing lifting clamps 2 is also installed on the lifting beam 11.
[0025] In use, after the forklift forks are inserted into the socket 12, the drive assembly 13 clamps the top plate 14 with the top surface of the socket 12 to achieve a rigid connection between the lifting frame 1 and the forklift forks. This is convenient to operate and adaptable to the fastening operations of forklift forks of different thicknesses. Subsequently, the lifting clamp 2 is used to hold the workpiece to complete the lifting. After the workpiece is placed stably, the drive assembly 13 is operated to move the top plate 14 downward (away from the top surface of the socket 12), releasing the clamping of the forklift forks. Then, the forklift is slowly pulled out to complete the disassembly.
[0026] For the specific structure of the driving component 13 in the above scheme, please refer to the appendix. Figure 1 and attached Figure 2As shown, the drive assembly 13 includes a screw 131 vertically mounted on the suspension beam 11. A crank 132 is connected to the top of the screw 131, and a connecting plate 133 is rotatably connected to the bottom. The connecting plate 133 is located below the suspension beam 11, and two slide rods 134 are vertically and symmetrically mounted on the connecting plate 133. The slide rods 134 pass through the suspension beam 11 and extend into the socket 12 to connect with the top plate 14.
[0027] In this solution, the screw 131 is rotated by the crank handle 132, which drives the connecting plate 133 and the slide rod 134 to rise and fall. The slide rod 134 then drives the top plate 14 to rise and tighten against the forklift forks. After the operation, the top plate 14 can be lowered by cranking the crank handle 132 in the opposite direction to release the fixation. The operation is simple and convenient.
[0028] In particular, considering the clamping effect of the top plate 14 on the forklift forks, therefore, refer to the attached... Figure 2 As shown, a spring 135 is sleeved on the outside of the slide bar 134, and the spring 135 is located between the connecting plate 133 and the lifting beam 11. The spring 135 can provide elastic preload to assist the top plate 14 in pressing against the forklift forks, enhancing the pressing effect and ensuring a more stable connection.
[0029] Of course, in other solutions, considering the clamping effect of the top plate 14 on the forklift forks, a spring 135 is fitted outside the screw 131, and the spring 135 is located between the connecting plate 133 and the lifting beam 11. The spring 135 can provide elastic preload to assist the top plate 14 in clamping the forklift forks, enhance the clamping effect, and ensure a more stable connection.
[0030] Additionally, refer to the appendix Figure 2 As shown, the top of the socket 12 is also provided with a rubber block 16 for contact with the forklift forks, which can enhance the friction and cushioning effect with the forklift forks.
[0031] In the above scheme, considering that the lifting clamp 2 facilitates the positioning and clamping of the workpiece, therefore, refer to the appendix. Figure 3 and attached Figure 4 As shown, the U-shaped frame 15 is connected to the lifting clamp 2 through the adjustment component 3 so that the lifting clamp 2 can move horizontally and rotate. Through the horizontal movement and rotation of the lifting clamp 2, a suitable clamping position for the workpiece can be found.
[0032] Specifically, regarding the structure of the adjustment component 3, the adjustment component 3 includes a sliding sleeve 31 that is horizontally slidably sleeved on the U-shaped frame 15. The sliding sleeve 31 is provided with an inner port seat 32. The bottom surface of the inner port seat 32 is provided with a through hole 321. The inner port seat 32 is provided with a limiting seat 33 whose size is smaller than its inner cavity and larger than the through hole 321. The limiting seat 33 is provided with an insertion rod 34. The insertion rod 34 passes through the through hole 321 and extends to the bottom of the inner port seat 32 to connect with the lifting clamp 2.
[0033] In this solution, the horizontal movement and rotation adjustment of the lifting clamp 2 can quickly find a suitable clamping position for the workpiece, improving operational flexibility and efficiency. The structure is simple and reliable. At the same time, when the workpiece is lifted by the lifting clamp 2, the sliding sleeve 31 and the limiting seat 33 will be subjected to a downward pull, so that the sliding sleeve 31 can closely abut against the U-shaped frame 15 and the limiting seat 33 can closely abut against the inner seat 32, thereby preventing the workpiece from wobbling significantly during the transfer process.
[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
