Description

Technical Field

[0001] This patent discloses an I-shaped wheel hoist, which belongs to the field of metallurgy industry and is used in the production of stainless steel wire for deep processing of stainless steel long wires. The stainless steel wire rod is surface treated, drawn by a wire drawing machine, rewound on an I-shaped wheel reel, and unwound on an unfolding heat treatment production line. In this process, the batches of I-shaped wheel reels fully loaded with steel wire need to be lifted and transferred by a crane using the hook described in this patent during the process transfer. Background Art

[0002] Modern large-scale stainless steel wire production enterprises all adopt large, heavy-loaded, coiled I-shaped wheels for weekly operation. The total coil weight of stainless steel wire rod parent material reaches about 2000KG; among them, the I-shaped wheels used for stainless steel wire generally adopt DIN800 standard with a bulk density of about 1000KG.

[0003] In order to achieve the technical indicators of stainless steel products and maintain the clean, bright surface and straightness of stainless steel products, the fully loaded I-shaped wheel wire base material must be unfolded and surface treated, dried, heat treated with multi-tube protective gas, and reeled. Therefore, the lifting, flipping, and shifting of the heavy I-shaped wheel reel become necessary and frequent operations. The traditional I-shaped wheel hook is two coaxial hooks hanging under the lifting center. Such a lifting tool requires the operator to manually buckle the two hooks one by one and then lift; after the I-shaped wheel reel is in place, the unhooking operation is also very cumbersome.

[0004] Therefore, it is necessary to develop an I-spool hoist that uses the characteristics of a hand-pulled hook to lift the I-spool by buckling the edge, which will effectively improve production efficiency and solve the problems of complicated operation and high labor intensity of the existing I-spool lifting device. In order to achieve the above-mentioned use needs and corresponding requirements, an I-spool hoist based on the above-mentioned situation and needs is specially invented. Utility Model Content

[0005] The technical problem to be solved by this patent is to provide an I-shaped wheel hoist to solve the problems of complicated operation and high labor intensity of the lifting device in the multiple lifting, moving and turning links of the I-shaped wheel coil used in the existing stainless steel wire deep processing link.

[0006] The main components of the I-shaped wheel hanger described in this patent include a central hanger rod, a cross arm, a support arm, a hanging arm, a connecting plate, and a connecting component.

[0007] Among them, the upper end of the central boom is a lifting ring, a sliding sleeve with horizontal arms on both sides is designed in the middle, and symmetrical support arms are welded at the lower end. Pin holes of the same specification are designed at the ends of the horizontal arms and the support arms.

[0008] Among them, the boom is a two-piece force arm structure of the same size and mirror-symmetric. A connecting pin hole is designed at the upper end of each boom, and a connecting pin hole of the same size is designed in the middle of the boom. An arc-shaped buckle for grabbing the I-wheel is welded at the lower end of the boom, and a rectangular handle ring is welded on the outer side of the lower part of the boom.

[0009] Among them, the hoist is in a closed boom state when it is free without any load, and the boom is opened by manually pulling the handle ring; when the hoist is in a coiled state with the I-shaped wheel mounted, the boom is in a closed state due to the gravity of the I-shaped wheel.

[0010] The connecting plate is a two-piece force arm structure of the same size, and pin holes of the same diameter are reserved at both ends of the connecting plate.

[0011] Among them, the connecting parts include threaded straight pins, positioning sleeves, flat washers, spring washers, slotted nuts, cotter pins, etc., totaling 4 sets.

[0012] The operation of the I-shaped wheel hoist described in this patent is as follows: (1) Assemble the above-mentioned components in the order described in the accompanying drawings; (2) Hang the entity of this patent through the lifting ring, the two booms droop due to their own weight, and the sliding sleeve on the center hook moves up; (3) The operator pulls the handle ring on either side of the boom outward, and the polygon formed by the connecting plate and the boom on both sides of the center boom is pulled laterally, and the two booms are opened to a diameter slightly larger than the I-shaped wheel; (4) The crane descends so that the inner side of the boom contacts the edge of the I-shaped wheel, and then lifts, and the boom droops and tightens due to its own weight; (5) Lift the described hoist again, at this time, the gravity of the I-shaped wheel causes the boom buckle and the boom to tighten inward, thereby realizing the lifting operation of the I-shaped wheel.
