Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of a special hoist for a large-plate heavy-duty wheel, and in particular relates to a special hoist for a large-plate heavy-duty wheel. Background Art
[0002] I-shaped wheels are tools used to wind metal wires or wire ropes. The specifications and materials of I-shaped wheels vary according to the materials and specifications of the wire ropes being wound. I-shaped wheels for winding steel wires are generally made of steel plates, but wooden I-shaped wheels can be used for winding thin steel wires and non-ferrous metal wires. The use of plastic I-shaped wheels is increasing day by day. Steel I-shaped wheels: They are welded and formed by reinforced thick plates, and are available in NTC, YA-40, etc., and are tested for dynamic balancing by machining. They have high strength, high rigidity, and good stability when retracting and releasing wires at high speeds. Plastic I-shaped wheels: They are injection molded using engineering plastics specially used for plastic cable drums. The products have high precision, advanced structure, and are reinforced with dense ribs on the side plates. They have the characteristics of good balancing performance, high strength, and resistance to acid and alkali corrosion. The balancing accuracy can reach above level 6.3. The overall structure is a combination of plastic and metal to ensure the shaft hole requirements and electrical conductivity. The product parts can be disassembled and replaced, and maintenance is convenient. Generally, I-shaped wheels of different strength and accuracy can be made according to the requirements of customer equipment. The disadvantage is that the retracting and releasing wires are long, and the flange will be deformed due to the large capacity.
[0003] When a large-disc heavy-duty I-shaped wheel is in use, it usually needs to be suspended by a crane. The existing hoisting equipment for large-disc heavy-duty I-shaped wheels usually adopts a hook to clamp on the side of a circular disc on one side of the I-shaped wheel. Since the side circular wheel of the large-disc heavy-duty I-shaped wheel is relatively large, the hook is prone to slip due to the change of angle during the hoisting process, which leads to the risk of deflection and falling during the hoisting process. In addition, there is a lack of buffering measures for the placement of the I-shaped wheel after hoisting, which is easy to cause damage to the I-shaped wheel due to impact with the ground.

The cam is pressed against the top of the support rod and the cam is pressed against the support rod to release the cam, and the cam is pressed against the support rod to release the cam, so that the cam is pressed against the support rod and the cam is pressed against the support rod.
[0013] Through the above technical solution, 1. The position to be clamped is adjusted by rotating the screw rod to drive the sliding plate. When the position is determined, the fixed plate is pushed downward by the cylinder to clamp the I-shaped wheel so that the I-shaped wheel will not shift during use.
[0014] 2. The bottom plate is used to prevent the whole from contacting with the ground and causing damage, and the shock-absorbing cotton strips 20 under the bottom plate are used to alleviate the vibration generated by the whole.
[0015] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
