Description

Technical Field

[0001] The utility model relates to the technical field of round barrel transportation, in particular to a hookless round barrel lifting device. Background Art

[0002] In daily production, the application scope of round barrels is becoming wider and wider. Usually, it is necessary to lift or lower them to the placement point. Generally, these round barrels are not equipped with lifting rings, resulting in inconvenient handling. If only manual handling is relied on, it not only increases the labor intensity of workers, but also may cause the round barrel to fall due to uncontrollable factors, resulting in accidents.

[0003] During the process of clamping and lifting a round barrel with an ordinary lifting tool, there is a lack of a necessary locking mechanism. As a result, under the influence of the weight inside the barrel or external force, the clamping mechanism is likely to loosen the clamping head, causing the round barrel to fall. Therefore, a lifting device with an automatic locking function is required to improve the lifting safety. Summary of the Utility Model

[0004] The utility model aims at the defects in the prior art and provides a hookless round barrel lifting device.

[0005] The utility model is realized by the following technical solutions:

[0006] A hookless round barrel lifting device includes a clamping mechanism, a locking device and a round barrel. The locking device is arranged on both sides of the clamping mechanism. The round barrel is clamped inside the bottom of the clamping mechanism. The clamping mechanism includes an outer beam, an inner beam, a pin shaft, a lock catch, a chain, a clamping head and an anti-slip pad. The inner beam is clamped inside the outer beam, and the inner beam and the outer beam are movably connected through the pin shaft. The lock catch is clamped on the tops of the outer beam and the inner beam. The chain is sleeved on the top of the lock catch. The clamping head is fixed to the bottoms of the outer beam and the inner beam. The anti-slip pad is arranged on the inner top of the clamping head.

[0007] In a preferred embodiment of the utility model, the locking device includes an installation box, a fixing plate, a guide rod, a sleeve, a spring, a pressing plate and a locking block. The fixing plate is fixedly arranged in the middle inside the installation box. The guide rod is fixedly arranged on both sides of the fixing plate. The sleeve is sleeved outside the guide rod. The pressing plate is fixedly arranged at one end of the sleeve. The locking block is fixedly arranged at the other end of the sleeve. The spring is sleeved outside the sleeve.

[0008] In a preferred embodiment of the utility model, a hanging ring protruding outwards is arranged on the outer side of the top of the round barrel, and the clamping head is clamped at the bottom of the hanging ring on the outer side of the top of the round barrel;

[0009] The main function of the locking device is that after lifting the round barrel, the locking block automatically gets stuck in the gap between the outer beam and the inner beam and applies a certain pressure, thereby preventing the outer beam and the inner beam from easily opening under the influence of external forces, ensuring an effective clamping effect on the round barrel and improving the lifting safety.

[0010] In a preferred embodiment of the present invention, a clamping groove matching with the inner beam is provided in the middle of the outer beam, and the inner beam is clamped in the clamping groove in the middle of the outer beam. The outer beam and the inner beam are in an S-shaped structure.

[0011] In a preferred embodiment of the present invention, one end of the sleeve penetrates and extends to the outside of one side of the installation box. The locking block is clamped between the outer beam and the inner beam, and a rubber anti-slip sleeve is arranged outside the locking block;

[0012] In a preferred embodiment of the present invention, the spring is arranged between the pressing plate and the inside of one side of the installation box. A dial is arranged outside the pressing plate. One end of the dial on the outside of the pressing plate penetrates and extends to the outside of one side of the installation box, and a sliding groove matching with the dial is arranged on the outside of the installation box;

[0013] Under the action of the spring, the sleeve automatically retracts inward, enabling the locking block to be clamped between the outer beam and the inner beam. The anti-slip sleeve on its surface effectively prevents the locking block from moving outward under extrusion. The dial facilitates the operation of the position of the pressing plate, thereby adjusting the position of the locking block and facilitating the disassembly of the clamping mechanism from the surface of the round barrel.

[0014] The beneficial effects of the present invention are:

[0015] The hookless round barrel lifting device clamps at the convex part on the outer side of the top of the round barrel through the clamping mechanism, facilitating the lifting operation of the round barrel. And during the clamping process, the locking device automatically limits the position between the outer beam and the inner beam, effectively preventing the outer beam and the inner beam from opening under external forces during lifting, ensuring the clamping effect on the round barrel, preventing the round barrel from falling, and improving the safety of lifting and transportation.

[0021] As Figures 1-3 shown, a hookless barrel lifting device includes a clamping mechanism 1, a locking device 2 and a barrel 3. The locking device 2 is arranged on both sides of the clamping mechanism 1, and the barrel 3 is clamped inside the bottom of the clamping mechanism 1. The clamping mechanism 1 includes an outer beam 11, an inner beam 12, a pin shaft 13, a lock 14, a chain 15, a clamping head 16 and an anti-slip pad 17. The inner beam 12 is clamped inside the outer beam 11, and the inner beam 12 and the outer beam 11 are movably connected by the pin shaft 13. The lock 14 is clamped on the tops of the outer beam 11 and the inner beam 12. The chain 15 is sleeved on the top of the lock 14. The clamping head 16 is fixed to the bottoms of the outer beam 11 and the inner beam 12. The anti-slip pad 17 is arranged on the inner top of the clamping head 16.

[0022] Specifically, the locking device 2 includes an installation box 21, a fixed plate 22, a guide rod 23, a sleeve 24, a spring 25, a pressure plate 26 and a locking block 27. The fixed plate 22 is fixedly arranged in the middle inside the installation box 21. The guide rod 23 is fixedly arranged on both sides of the fixed plate 22. The sleeve 24 is sleeved outside the guide rod 23. The pressure plate 26 is fixedly arranged at one end of the sleeve 24. The locking block 27 is fixedly arranged at the other end of the sleeve 24. The spring 25 is sleeved outside the sleeve 24. There is a hanging ring protruding outward on the outer side of the top of the barrel 3. The clamping head 16 is clamped at the bottom of the hanging ring on the outer side of the top of the barrel 3. A clamping groove matching with the inner beam 12 is opened in the middle of the outer beam 11. The inner beam 12 is clamped in the clamping groove in the middle of the outer beam 11. The outer beam 11 and the inner beam 12 are in an S-shaped structure. One end of the sleeve 24 penetrates and extends to the outside of one side of the installation box 21. The locking block 27 is clamped between the outer beam 11 and the inner beam 12. A rubber anti-slip sleeve is arranged outside the locking block 27. The spring 25 is arranged between the pressure plate 26 and the inside of one side of the installation box 21. A dial is arranged outside the pressure plate 26. One end of the dial outside the pressure plate 26 penetrates and extends to the outside of one side of the installation box 21. A sliding groove matching with the dial is opened on the outside of the installation box 21.

[0023] In this embodiment, due to the influence of the locking device 2, when the barrel 3 is not clamped, the bottom of the outer beam 11 and the inner beam 12 is in a closed state. At this time, it is necessary to move the paddle outside the pressing plate 26 outward to control the spring 25 of the pressing plate 26 to contract. At this time, the sleeve 24 can be moved outward, so that the locking block 27 is pushed outward, so that the clamping head 16 at the bottom can be opened. After the clamping head 16 is clamped to the bottom of the convex part at the top of the barrel 3, the hook is sleeved in the hanging ring at the top of the chain 15 and lifted. Since the outer beam 11 and the inner beam 12 are lifted at the top, the top of the outer beam 11 and the inner beam 12 contract, so that the outer beam 11 and the inner beam 12 rotate around the connecting pin shaft 13, so as to realize the clamping of the barrel 3 by the clamping head 16 at the bottom. The anti-slip pad 17 at the inner top of the clamping head 16 effectively plays an anti-slip effect, so that the lifting work of the barrel 3 can be realized.

[0024] Furthermore, when the barrel 3 is lifted, the locking device 2 automatically plays a locking effect. At this time, the spring 25 resets to push the pressing plate 26, causing the sleeve 24 to contract. Thus, the locking block 27 is automatically clamped in the gap between the outer beam 11 and the inner beam 12. The guide rod 23 effectively guides the movement of the sleeve 24 and facilitates the installation work of the sleeve 24. The surface of the locking block 27 is sleeved with an anti-slip sleeve. The locking block 27 clamped between the gaps of the outer beam 11 and the inner beam 12 effectively prevents the clamping head 16 from automatically opening under the influence of the gravity and external force of the barrel 3, resulting in the problem of the barrel 3 falling, effectively improving the lifting safety.

[0025] It should be noted that the parts not involved in the present invention are the same as or can be implemented by the prior art; various drives in the present invention can be implemented by corresponding power structures such as cylinders, oil cylinders, electric cylinders, motors, etc. in cooperation with connecting rods, guide rods, etc., and are not limited to the descriptions in the specification and the structures in the drawings.
