Description

Technical Field

[0001] This utility model relates to the field of lifting equipment technology, and more specifically, to a lifting device particularly suitable for lifting cylindrical objects without lifting interfaces. Background Technology

[0002] In engineering hoisting, conventional methods for lifting large cylindrical objects such as pipes and rollers without lifting joints, such as using a single sling to secure the center of gravity or directly supporting the bottom, have significant drawbacks. The former makes it difficult to maintain horizontality when lifting long and heavy objects, requiring manual straightening, and single-point stress can easily cause deformation of the cylindrical object; the latter, because there is no fixed connection between the sling and the cylindrical object, is prone to relative movement during lifting, posing a significant safety risk. Therefore, there is an urgent need for a specialized device that can reliably clamp and horizontally lift objects. Utility Model Content

[0003] The purpose of this utility model is to provide a cylindrical object lifting device to solve the problems of low safety, easy deformation of objects, and inability to guarantee horizontal lifting in existing lifting methods.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A cylindrical object lifting device includes a lifting beam, a U-shaped shackle, an adapter, and a clamping mechanism.

[0006] The lifting beam is provided with multiple U-shaped shackle mounting holes, multiple adapter connection holes, and multiple clamping mechanism mounting threaded holes.

[0007] The U-shaped shackle is installed in the U-shaped shackle mounting hole.

[0008] The adapter is connected to the adapter connection hole via a quick-connect pin one. The adapter includes a lifting block, a quick-connect pin two, and a sling. The sling is connected to the lifting block via the quick-connect pin two.

[0009] The screw of the clamping mechanism is screwed into the mounting threaded hole of the clamping mechanism, and the clamping mechanism includes a screw and a clamping assembly driven by the screw.

[0010] Preferably, the clamping assembly includes an arc plate and a rubber pad fixed to the bottom surface of the arc plate.

[0011] Preferably, the bottom end of the screw is provided with a ball head, and the top of the arc plate is provided with a ball socket that mates with the ball head. The screw is connected to the arc plate through the mating of the ball head and the ball socket.

[0012] More preferably, the clamping mechanism further includes a connecting plate, which uses a spring pin and screws to constrain the ball head of the screw within the ball socket of the arc plate.

[0013] Preferably, a handle for manual rotation is fixed on the screw.

[0014] More preferably, the handle is detachably fixed to the top of the screw by a nut.

[0015] More preferably, a second handle for assisting installation and rotation is also fixed on the screw.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. High safety: The active pressing mechanism greatly increases the static friction between the device and the cylindrical object, fundamentally preventing movement and slippage during the lifting process.

[0018] 2. High adjustability and versatility: The position of the core components on the lifting beam is adjustable, and the clamping components can be replaced, which can accurately adapt to cylindrical objects of different specifications, ensuring horizontal lifting and avoiding deformation.

[0019] 3. Good protection: The double slings provide symmetrical lifting and even force distribution; the ball joint and rubber pad design can evenly distribute the clamping force and protect the surface of the object.

[0020] 4. Easy to operate: It adopts quick-release pins and detachable handles, which can be quickly assembled and disassembled, significantly improving work efficiency. Attached Figure Description

[0027] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0028] like Figures 1 to 5 As shown, the cylindrical lifting device in this embodiment mainly consists of a lifting beam 1, a U-shaped shackle 2, an adapter 3, and a clamping mechanism 4. During assembly, the U-shaped shackle 2 is inserted into the selected U-shaped shackle mounting hole 5 on the lifting beam 1; the adapter 3 is connected to the selected adapter connection hole 6 via a quick-release pin 9; the screw 12 of the clamping mechanism 4 is screwed into the selected clamping mechanism mounting threaded hole 7. Inside the adapter 3, a second quick-release pin 10 connects the sling 11 to the lifting block 8; inside the clamping mechanism 4, the ball head of the screw 12 is embedded in the ball socket of the arc plate 15 and is constrained and fixed by a connecting plate 13, a spring pin 14, and a screw 19. A rubber pad 16 is attached to the bottom of the arc plate 15, a first handle 17 is fixed to the top of the screw 12 by a nut 20, and a second handle 18 is fixed to the lower part of the screw 12.

[0029] Its working process is as follows:

[0030] Based on the length, diameter, and center of gravity of the cylindrical objects 21 of different specifications, insert the U-shaped shackle 2 into the selected U-shaped shackle mounting hole 5 on the lifting beam 1. Connect the adapter 3 to the selected adapter connection hole 6 through the quick-release pin 9. Screw the screw 12 of the clamping mechanism 4 into the appropriate clamping mechanism mounting threaded hole 7 on the lifting beam 1 using the operating handle 18. Then install the handle 17 and nut 20. By removing and installing the screws 19, replace the cylindrical plates 15 and rubber pads 16 of different sizes to achieve the lifting of cylindrical objects 21 of different specifications.

[0031] Next, remove the quick-release pin 10, allow the sling 11 to catch the bottom of the cylindrical object 21, and then insert it back in to secure it. Rotate the handle 17 clockwise to drive the arc plate 15 and rubber pad 16 to press the top of the cylindrical object 21 firmly. After confirming that the pressing is reliable, safe lifting can proceed. After the operation is completed, rotate the handle 17 counterclockwise to release the pressing and remove the sling 11.
