Description

Technical Field

[0001] This utility model relates to the field of lifting equipment technology, and in particular to a lifting equipment with a fastening structure. Background Technology

[0002] Today, lifting tools refer to the devices used in lifting machinery to lift heavy objects. The most commonly used lifting tools for lifting packaged items are hooks and slings. Others include lifting rings, lifting suction cups, clamps, and forks, which are widely used in the lifting and hoisting industry.

[0003] Most existing lifting devices use hooks to lift goods after they are tied together. However, when lifting goods with hooks, it is impossible to clamp the goods. Therefore, the goods often sway when lifted into the air, which can increase the stress on the lifting device, causing damage to the device and the goods to fall. To address these issues, a solution is proposed below. Utility Model Content

[0004] The purpose of this invention is to provide a lifting device with a fastening structure to solve the problems mentioned in the background art.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A lifting device with a fastening structure includes a support frame and two clamping plates. The two clamping plates are symmetrically slidably disposed on both sides of the bottom of the support frame. A driving component for moving the clamping plates is installed on both sides of the bottom of the support frame. Two sliding grooves are symmetrically opened on the bottom of the support frame. The top of the clamping plate is slidably disposed in the sliding groove. The sliding groove has a T-shaped structure with a diameter that is larger at the top and smaller at the bottom. The top of the clamping plate is T-shaped to match the sliding groove. The clamping plate adopts a telescopic structure. A support plate is installed on the bottom side wall of the clamping plate.

[0007] Preferably, the clamping plate includes a support clamping plate and an adjusting clamping plate. The support clamping plate is slidably disposed at the bottom of the support frame. A cavity is formed inside the support clamping plate, and a connecting groove communicating with the cavity is formed at the bottom of the support clamping plate. The adjusting clamping plate is adapted to the connecting groove and is slidably disposed in the connecting groove and the cavity. A limiting plate is fixed at the top of the adjusting clamping plate. The diameter of the limiting plate is larger than the diameter of the connecting groove. The support clamping plate is also provided with a limiting member for limiting and fixing the adjusting clamping plate.

[0008] Preferably, the limiting component is a locking bolt, and multiple through limiting holes are provided on the end face of the adjusting clamp. Each of the two end faces of the supporting clamp is provided with an assembly hole communicating with the cavity. The two assembly holes cooperate with the through limiting holes, and the two assembly holes are correspondingly set. The locking bolt is installed by passing through the two assembly holes and the through limiting holes respectively. The locking bolt is fixed by installing a locking nut.

[0009] Preferably, support plates are installed on both sides of the bottom of the support frame, and the two driving components are installed on the side walls of the support plates. A support rod is also installed between the two support plates, and the support rod passes through the two support plates respectively.

[0010] Preferably, an extension plate may be installed on the top of the support plate, and the extension plate is fixed to the support plate by bolts.

[0011] Preferably, the driving component is a hydraulic push rod, and the piston rod of the hydraulic push rod is fixedly connected to the support clamp.

[0012] Beneficial effects: When lifting goods using a lifting device, the support frame can be moved to a designated height via an external lifting structure. The workpiece to be lifted is then moved between the two clamping plates. By activating the hydraulic push rods on both sides, the two clamping plates can be moved, achieving stable clamping of the workpiece. Compared to existing hook clamping technology, the clamping plates designed in this application can firmly clamp the workpiece, preventing it from swaying during lifting. The support plate at the bottom of the clamping plate can support the workpiece, facilitating its clamping. The T-shaped sliding groove and support rod inside the support frame provide double support for the clamping plate, improving its strength. The telescopic design of the clamping plate allows the extension distance to be adjusted according to the size of the workpiece, improving the practicality of the lifting device and enabling it to clamp and lift workpieces of different sizes.

[0019] See Figures 1 to 5 As shown, a lifting device with a fastening structure includes a support frame 1 and two clamping plates 2. The two clamping plates 2 are symmetrically slidably arranged on both sides of the bottom of the support frame 1. Both sides of the bottom of the support frame 1 are equipped with driving components 3 for moving the clamping plates 2. When it is necessary to use the lifting device to lift goods, the support frame 1 can be moved to a specified height by an external lifting structure, and the workpiece to be lifted can be moved between the two clamping plates 2. The driving component 3 is a hydraulic push rod, and the piston rod of the hydraulic push rod is fixedly connected to the clamping plate 2. By activating the hydraulic push rods on both sides, the hydraulic push rods can push the two clamping plates 2 to move, and the workpiece can be stably clamped by the two clamping plates 2. Compared with the existing hook clamping technology, the clamping plate 2 clamping designed in this application can fasten the workpiece and prevent the workpiece from shaking during lifting.

[0020] A support plate 5 is installed on the bottom side wall of the clamping plate 2. By installing the support plate 5 on the side wall of the clamping plate 2, the two support plates 5 can be located at the bottom of the workpiece when the two clamping plates 2 are moved by the hydraulic push rod. The two support plates 5 support the bottom of the workpiece, which facilitates better hoisting of the workpiece and improves the safety of hoisting. The opposite surfaces of the two support plates 5 are set at an inclination. The inclination of the support plates 5 makes it easier to push the workpiece onto the two support plates 5.

[0021] An extension plate 16 can also be installed on the top of the support plate 5. The extension plate 16 is fixed to the support plate 5 by bolts. When the width of some workpieces is too long and the support plate 5 cannot provide adequate support, the extension plate 16 can be installed on the top of the support plate 5 to extend the length of the support plate 5, so that the support plate 5 can better support the workpiece. The top of the support plate 5 has a through groove, and the extension plate 16 can be installed into the through groove. The through groove limits the position of the extension plate 16. After the extension plate 16 is installed, it can be fixed to the top of the support plate 5 by bolts. The extension plate 16 and the support plate 5 are installed with countersunk holes to prevent the protruding part of the bolt from affecting the support of the workpiece.

[0022] The bottom of the support frame 1 is symmetrically provided with two sliding grooves 4. The top of the clamping plate 2 is slidably disposed in the sliding grooves 4. The sliding grooves 4 have a T-shaped structure with a cross-sectional dimension that is larger at the top and smaller at the bottom. The top of the clamping plate 2 is T-shaped to match the sliding grooves 4. In order to better support and protect the clamping plate 2, the sliding grooves 4 are provided on the top of the support frame 1. The top of the clamping plate 2 slides in the sliding grooves 4. The T-shaped structure of the clamping plate 2 and the sliding grooves 4 can prevent the clamping plate 2 from coming out of the sliding grooves 4, and play a limiting role, ensuring that the clamping plate 2 slides stably in the sliding grooves 4, improving the overall stability of the lifting device. Compared with simple straight lines or other shapes, the T-shaped structure can better disperse stress when subjected to tension and pressure, making the connection between the support frame 1 and the clamping plate 2 more solid, improving the load-bearing capacity and structural strength of the lifting device, extending its service life, and also providing a clear guide path for the sliding of the clamping plate 2, making the movement of the clamping plate 2 more stable.

[0023] Support plates 14 are installed on both sides of the bottom of support frame 1. Two drive components 3 are mounted on the side walls of support plates 14. Support rods 15 are installed between the two support plates 14, passing through both clamping plates 2 and two support clamping plates 6, and are positioned between the support plates 14. This design enhances the overall structural stability of the lifting device. When lifting goods, the lifting device needs to withstand significant weight and complex stress conditions. Support rods 15 effectively distribute and transmit the pressure on the clamping plates 2, preventing deformation or displacement of the clamping plates 2 under stress. Simultaneously, it strengthens the connection between support frame 1 and support plates 14, ensuring the stability of the entire lifting device frame structure during lifting operations, reducing swaying and vibration, and improving the safety and reliability of the lifting process.

[0024] The clamping plate 2 adopts a telescopic structure. This telescopic design allows the clamping plate 2 to adjust its extension distance according to the size of the workpiece being clamped. The telescopic clamping plate 2 makes the lifting device more versatile, adaptable to various sizes of goods, eliminating the need for specialized lifting devices for each workpiece size. This reduces equipment procurement and management costs for enterprises, and improves the efficiency and economic benefits of the lifting device. When not in use, the telescopic clamping plate 2 can be retracted to a shorter length, reducing the overall size of the lifting device, facilitating transportation and storage, and saving space. In contrast, using a longer clamping plate 2 would require more space, increasing transportation and storage costs and difficulties.

[0025] The clamping plate 2 includes a support clamping plate 6 and an adjusting clamping plate 7. The support clamping plate 6 is slidably disposed at the bottom of the support frame 1. A cavity 8 is opened inside the support clamping plate 6, and a connecting groove 9 communicating with the cavity 8 is opened at the bottom of the support clamping plate 6. The adjusting clamping plate 7 is adapted to the connecting groove 9 and is slidably disposed in the connecting groove 9 and the cavity 8. A limit plate 10 is fixed at the top of the adjusting clamping plate 7. The diameter of the limit plate 10 is larger than the diameter of the connecting groove 9. When the workpiece is being hoisted, the operator can adjust the extension distance of the adjusting clamping plate 7 in advance according to the height of the workpiece. The adjusting clamping plate 7 is limited in movement by the limit plate 10 installed at the top, preventing the adjusting clamping plate 7 from being pulled directly out of the cavity 8. The extension distance of the adjusting clamping plate 7 can be adjusted by moving the adjusting clamping plate 7 up and down. The support clamping plate 6 is also provided with a limiting member 11 for limiting and fixing the adjusting clamping plate 7. When the adjusting clamping plate 7 moves to the designated position, it can be fixed by the limiting member 11.

[0026] The limiting component 11 uses locking bolts. Multiple through-holes 12 are provided on the end face of the adjusting clamp 7. Assembly holes 13 communicating with the cavity 8 are provided on both end faces of each supporting clamp 6. The two assembly holes 13 mate with the through-holes 12, and the two assembly holes 13 are correspondingly positioned. Locking bolts are installed by passing through the two assembly holes 13 and the through-holes 12. The locking bolts are fixed by installing locking nuts. When the adjusting clamp 7 moves to the designated position, the locking bolts can be inserted into the assembly holes 13. The locking bolts will then enter the cavity 8 after passing through the assembly holes 13. At this point, slight adjustments can be made. Adjust the vertical position of the clamping plate 7 so that the through-limiting hole 12 on the clamping plate 7 corresponds to the assembly hole 13 on the support clamp. The locking bolt can be inserted into the through-limiting hole 12 and can pass through the through-limiting hole 12 and out through the assembly hole 13 on the other side. The locking bolt can then be fixed by installing a washer and a locking nut. In order to better support and fix the clamping plate 7, two assembly holes 13 can be opened on one side wall of the support clamping plate 6. By installing two locking bolts, the stress on a single bolt can be reduced, and the stability of the clamping plate 7 can be improved.
