Description

Technical Field

[0001] The utility model relates to a non-standard lifting device, in particular to a disassembly-free lifting device. Background Art

[0002] Traditional multi-joint non-standard slings are suitable for civil construction and machinery manufacturing industries. Multi-joint non-standard slings are used in conjunction with various lifting equipment to achieve the purpose of lifting various prefabricated medium and large components.

[0003] The field of engineering machinery requires multi-joint non-standard spreaders to be compact in size and easy to store and carry. Multi-joint non-standard spreaders are composed of pull plates, box beams, pins, vertical pins, pin pins and other devices. The pull plates are placed across the box beams and connected by inserting the pins. After the pins are inserted, the vertical pins and pin pins must be inserted at the front end to prevent them from falling off.

[0004] Due to the large load lifting capacity requirement of the pull plate of the multi-joint non-standard sling, its own weight is about 0.5t. There is no rigid support and fixation between it and the box beam. It needs to be disassembled from the box beam and other components during transportation. Otherwise, the arbitrary swing of the pull plate may collide with the ground or the transport vehicle, causing damage to the pull plate and making it unable to reach the designed lifting load capacity, posing a safety hazard during use.

[0005] When the pull plate of the multi-joint non-standard lifting device is disassembled from the box beam, not only the pin shaft, vertical pin and pin pin need to be disassembled and assembled, but also the lifting equipment needs to be used for hoisting when it is reassembled, which consumes a lot of time and incurs additional costs. Utility Model Content

[0007] The lifting beam is used to support heavy objects. A pull plate is hinged at both ends of the lifting beam. The other end of the pull plate is provided with a hanging part for hanging a hook. A self-locking component is fixedly connected at both ends of the lifting beam. The self-locking component includes a self-locking pin, a compression spring and a shell. The self-locking pin includes a self-locking part, a first sliding part, a second sliding part and a compression spring matching part. The compression spring matching part is arranged between the first sliding part and the second sliding part. The shell is provided with a first sliding hole and a second sliding hole. The aperture of the first sliding hole is smaller than the outer diameter of the compression spring matching part. The first sliding part is slidably arranged in the first sliding hole, and the second sliding part is slidably arranged in the second sliding hole.

[0008] The compression spring is sleeved on the outside of the second sliding part, one end of the compression spring abuts against the inner wall of the shell, and the other end abuts against the compression spring matching part.

The connecting pipe is fixedly connected to the pull plate, and a connecting hole is provided on the connecting pipe for clamping the self-locking pin when the pull plate is rotated to a preset position.

[0009] When storing the sling, lower the hook, remove the two pull plates from the hook, and then rotate the pull plates to both sides. The connecting tube on the pull plate first touches the self-locking pin. As the pull plate continues to rotate, the self-locking pin is compressed into the shell until the axis of the self-locking pin is aligned with the center of the connecting hole on the connecting tube. The self-locking pin is ejected by the compression spring and inserted into the connecting hole. At this point, the rotational freedom of the pull plate around the suspension beam is locked. When unfolding the sling, pull the end of the second sliding part outward from the second sliding hole, so that the self-locking part retracts into the shell, and then rotate the two pull plates to unlock the rotational freedom of the pull plate around the suspension beam.

[0010] Furthermore, the compression spring fitting portion is provided with a compression spring abutting surface and a sliding hole abutting surface, the compression spring abutting surface is used to abut the compression spring, and the sliding hole abutting surface is used to abut the inner wall of the shell corresponding to the first sliding hole.

[0011] Furthermore, the suspension beam comprises an articulated seat and a self-locking seat, the pull plate is articulated to the suspension beam by being articulated to the articulated seat, and the self-locking assembly is fixedly connected to the suspension beam by being fixedly connected to the self-locking seat.

[0012] Furthermore, the hinge seat includes a pin shaft, a pin shaft hole is provided on the hinge seat, the pin shaft is arranged in the pin shaft hole, a through hole matching the pin shaft is provided on the pull plate, and the pull plate is hinged to the hinge seat through the pin shaft.

[0013] Furthermore, the hinge seat also includes a vertical pin, a vertical pin hole is provided on the pin shaft, and the vertical pin is arranged in the vertical pin hole for fixing the pin shaft.

[0014] Furthermore, the hinge seat also includes a pin pin, and the vertical pin is provided with a pin pin hole, and the pin pin is arranged in the pin pin hole for fixing the vertical pin.

[0015] Furthermore, the self-locking seat also includes a matching groove, which is used to accommodate the connecting pipe when the pull plate is rotated to a preset position.

[0016] Furthermore, the self-locking seat also includes a mounting tube, the outer side of the shell is provided with a thread, and the inside of the mounting tube is provided with an adaptable thread, and the self-locking component is fixed to the self-locking seat through a threaded connection.

[0017] Furthermore, the self-locking seat also includes a locking nut, in which a thread matching the thread on the outer side of the shell is provided, and the self-locking component is locked through a threaded connection.

[0018] The utility model avoids the need to disassemble and store the pull plates of the multi-joint sling, facilitates the storage of the sling, and avoids the hidden danger of damage and loss during separate transportation and storage caused by the disassembly and storage.
