Description

Technical Field

[0001] This utility model relates to the field of self-locking cylinder lifting devices, and in particular to an adjustable distance self-locking cylinder lifting device. Background Technology

[0002] In modern industrial production and logistics, self-locking cylinder lifting devices are widely used as important material handling equipment in machinery manufacturing, warehousing and logistics, and port loading and unloading. With their high efficiency and safety features, they undertake the lifting and transfer of various types of goods, playing a crucial role in improving production efficiency and ensuring operational safety.

[0003] Currently, most self-locking cylinder lifting devices on the market adopt traditional mechanical structures, mainly consisting of a fixed clamping arm, a movable clamping arm, a drive unit, and a locking mechanism. The technical principle is that the drive unit moves the movable clamping arm closer to or further away from the fixed clamping arm, thereby clamping and releasing the goods. The locking mechanism keeps the clamping arm in a fixed position after the goods are clamped. In actual operation, the drive unit is usually hydraulic or electric, providing power for the opening and closing of the clamping arms.

[0004] However, existing self-locking cylinder-type spreaders generally suffer from limited clamping range. Due to the relatively simple adjustment method of their clamping arm distance and the lack of a precise control mechanism, they often struggle to effectively clamp excessively large or small loads. Forcing the use of such spreaders to handle loads exceeding their clamping range not only leads to the load falling and being damaged, but also damages the spreader's own structure, severely limiting its application in diverse operational scenarios. Therefore, an adjustable-distance self-locking cylinder-type spreader is proposed to address these issues. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an adjustable distance self-locking cylinder lifting tool, which aims to improve the existing technology and solve the problem of limited clamping range of lifting tools, making it difficult to clamp goods that are too large or too small.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Includes a main frame and crossbeams: the bottom of the main frame is fixedly connected to the top of multiple crossbeams, a fixing plate is fixedly connected to one side of each crossbeam, a card seat is fixedly connected between two adjacent fixing plates, a protective shell is slidably connected to the outer wall of each card seat, multiple sliding buttons are slidably connected inside the multiple protective shells, multiple connecting shells are fixedly connected to the bottom of the multiple protective shells, a clamping arm is slidably connected to the inner wall of each connecting shell, and an adjustable component is provided inside the protective shell;

[0008] The adjustable component includes multiple springs and buckles, which are located inside the protective shell. A connecting block is fixedly connected to the top of the inner wall of the protective shell. Multiple buckles are slidably connected to the outer wall of the connecting block. The buckles engage with the slots. Multiple springs are provided inside the connecting block. The two ends are fixedly connected between two adjacent springs. A sliding button is fixedly connected to the top of each buckle. A buffer component is provided inside the connecting shell.

[0009] As a further description of the above technical solution:

[0010] The buffer assembly includes multiple springs 2 and 3, which are located inside the connecting shell. Multiple force-bearing connecting plates 1 and pistons are fixedly connected to the inner wall of the clamping arm.

[0011] As a further description of the above technical solution:

[0012] Each of the force-bearing connecting plates has a rotating bar inside, and each rotating bar has a connecting rod rotatably connected to its outer wall.

[0013] As a further description of the above technical solution:

[0014] Each of the connecting rods is fixedly connected to one end with a rotating bar II, and each of the rotating bars II is rotatably connected to a force-bearing connecting plate II on its outer wall.

[0015] As a further description of the above technical solution:

[0016] Each of the two force-bearing connecting plates has a connecting plate fixedly connected to one side, and each of the connecting plates has a guide rod slidably connected inside.

[0017] As a further description of the above technical solution:

[0018] Multiple guide rods are fixedly connected to multiple fixing blocks at both ends, and each fixing block is fixedly connected to a connecting cylinder on one side.

[0019] As a further description of the above technical solution:

[0020] Each of the connecting cylinders is equipped with a spring three inside, one end of each spring three is fixedly connected to a piston, the other end of each spring three is fixedly connected to one side of a fixing block, and each piston is slidably connected to the inner wall of the connecting cylinder.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, by pressing the operation button, the movement position of the buckle inside the slot plate can be adjusted, thereby precisely adjusting the clamping distance range of the clamping arm. This process allows the clamping distance of the spreader to be flexibly adjusted according to the needs, ultimately achieving precise control of the clamping distance size to meet the specific requirements of different lifting tasks. This solves the problem of limited clamping range of lifting tools, making it difficult to clamp goods that are too large or too small, and improves the spreader's adaptability to goods of different sizes.

[0025] 2. The internal buffer structure of this utility model can absorb and disperse impact force, effectively reduce the transmission of vibration in the structure, improve the overall shock resistance, and ensure that the clamping arm can maintain stable operation during the clamping of goods. It solves the problem of severe vibration of the clamping arm, goods slipping or damage to the clamping arm structure caused by impact force during the lifting process of traditional lifting tools. It avoids the problem of decreased clamping arm opening and closing accuracy and unstable goods clamping caused by vibration, thereby improving the safety and stability of the operation.

A fixing plate 3 is fixedly connected to one side of each crossbeam 2. A card seat 4 is fixedly connected between two adjacent fixing plates 3. A protective shell 5 is slidably connected to the outer wall of each card seat 4. Multiple sliding buttons 6 are slidably connected inside the multiple protective shells 5. Multiple connecting shells 7 are fixedly connected to the bottom of the multiple protective shells 5. A clamping arm 8 is slidably connected to the inner wall of each connecting shell 7. An adjustable component is provided inside the protective shell 5.

[0035] The adjustable component includes multiple springs 10 and buckles 11, which are located inside the protective shell 5. A connecting block 9 is fixedly connected to the top of the inner wall of the protective shell 5. The connecting block 9 is slidably connected to the multiple buckles 11 on the outer wall. The buckles 11 engage with the slots 23. Multiple springs 10 are provided inside the connecting block 9. The two ends of each spring 10 are fixedly connected between two adjacent buckles 11. A sliding button 6 is fixedly connected to the top of each buckle 11. A buffer component is provided inside the connecting shell 7.

[0036] Reference Figures 2-5The buffer assembly includes multiple springs 16 and 17, which are located inside the connecting shell 7. Multiple force-bearing connecting plates 20 and pistons 22 are fixedly connected to the inner wall of the clamping arm 8. Each force-bearing connecting plate 20 has a rotating bar 18 inside, and a connecting rod 19 is rotatably connected to the outer wall of each rotating bar 18. One end of each connecting rod 19 is fixedly connected to a rotating bar 21, and a force-bearing connecting plate 24 is rotatably connected to the outer wall of each rotating bar 21. A connecting plate 15 is fixedly connected to one side of each force-bearing connecting plate 24. Guide rods 14 are slidably connected inside the plate 15. Multiple guide rods 14 are fixedly connected to both ends of multiple fixing blocks 13. Each fixing block 13 is fixedly connected to one side of a connecting cylinder 12. Each connecting cylinder 12 is provided with a spring 3 17. A piston 22 is fixedly connected to one end of each spring 3 17. The other end of each spring 3 17 is fixedly connected to one side of the fixing block 13. Each piston 22 is slidably connected to the inner wall of the connecting cylinder 12. One end of multiple pistons 22 is fixedly connected to the inner wall of the clamping arm 8. One side of multiple fixing blocks 13 is fixedly connected to the inner wall of the connecting shell 7.

[0037] Working principle: When it is necessary to adapt to different specifications of goods and adjust the clamp spacing, the operator presses the sliding button 6, causing the buckle 11 to press inward against the spring 10, disengaging from the restraint of the clamping groove 23 limit structure; then pushes the connecting block 9, making it move precisely along the slide of the clamping seat 4. After reaching the predetermined position, the operator releases the sliding button 6, and the buckle 11 returns to its original position due to its own elasticity, re-clamping into the clamping groove 23. This achieves the adjustment of the clamp spacing during operation, effectively preventing the problem of clamping and adapting different specifications of goods, and ultimately realizing the controllable adjustment of the clamp spacing, making it easy to adapt to the clamping of different specifications of goods. In terms of buffering, when the clamping arm 8 is squeezed internally, it squeezes the first connecting plate 20 and the piston 22 respectively. Since the two ends of the connecting rod 19 are rotatably connected to the first connecting plate 20 and the second connecting plate 24, the first connecting plate 20 rotates during the movement, causing the connecting rod 19 to rotate. Finally, during the rotation of the connecting rod (19), the connecting plate 15 on one side of the second connecting plate 24 squeezes the second spring 16 inward on the outer wall of the guide rod 14. Similarly, the piston 22 is forced to squeeze the third spring 17 inward. The second spring 16 and the third spring 17 rebound the first connecting plate 20 and the piston 22, thereby achieving the buffering effect. In the end, the lifting device effectively protects the goods during the lifting process, effectively preventing damage to the goods caused by the impact force generated during the lifting process, and ensuring the stability and safety of the lifting.
