Marked in the figure as: 1. a lifting hook; 2. a hanging ring; 3. a bearing seat; 4. bolt holes.

Detailed Description

The following detailed description of the embodiments of the utility model, given by way of example only, is presented in the accompanying drawings to aid those skilled in the art in a more complete, accurate and thorough understanding of the inventive concepts and aspects of the utility model, and to facilitate their practice.

As shown in fig. 1 and 2, the lifting tool for the bearing seat dismounting process comprises a lifting hook 1, wherein the top end of the lifting hook 1 is fixedly connected with a lifting ring 2, the upper end of the bearing seat 3 is provided with a bolt hole 4, and the end part of the lifting hook 1 extends into the bolt hole 4.

This lifting means that bearing frame dismouting process was used has fully considered the appearance structure of current bearing frame 3, designs according to current bolt hole 4 structure, obtains lifting hook 1 and rings 2 of this kind of integral type structure, has replaced loaded down with trivial details iron wire process of binding, can effectively improve dismouting efficiency.

As shown in fig. 1, the middle part of the lifting hook 1 is of a V-shaped structure, and two ends of the lifting hook are of a U-shaped structure. The lifting hook 1 is formed by bending round steel, and the middle part of the lifting hook 1 is designed into a V-shaped structure, so that the lifting ring 2 can be conveniently fixed by welding; the two ends of the lifting hook 1 are arranged in parallel, can be just inserted into the bolt holes 4 of the bearing seat 3, and can disperse stress; the two ends of the hanging ring 2 and the hanging hook 1 form a triangle structure, so that the stability of the hanging can be improved during the hanging, and the shaking of the bearing seat 3 is reduced.

As shown in fig. 2, the distance between two ends of the lifting hook 1 is matched with the distance between the bolt holes 4. The distance between the bottom ends of the lifting hooks 1 is determined by the distance between the bolt holes 4, and the distance between the bottom ends of the corresponding lifting hooks 1 is designed according to the model of the bearing seat 3 to be disassembled and assembled.

The length of the bottom end of the lifting hook 1 is consistent with the depth of the bolt hole 4. After the lifting hook 1 stretches into the bolt hole 4, the horizontal parts at the two ends of the lifting hook 1 can be completely contacted with the inner wall of the bolt hole 4, so that the bearing seat 3 cannot slide and fall off due to uneven stress areas, and the use safety is improved.

The lifting hook 1 and the lifting ring 2 are formed by bending round steel. The lifting hook 1 is formed by bending round steel, the round steel raw material cost is low, the round steel waste parts or leftover materials can be adopted for manufacturing, the manufacturing is convenient and simple, and the materials on the overhaul site can be manufactured at any time and used at any time.

The lifting hook 1 and the lifting ring 2 are fixed through welding. The lifting hook comprises a lifting ring 2 and a lifting hook 1, which are formed by bending round steel, and are welded together after being bent, and welding is required to be reliable and firm, and the lifting hook is welded and fixed, so that the lifting hook is convenient to process, and meanwhile, the lifting hook 1 and the lifting ring 2 are ensured to be firmly connected. And the round steel structure has high strength, high reliability and durability and can be recycled.

The hanging ring 2 is positioned right above the middle part of the bearing seat 3. During hoisting, the hoisting ring 2 can be ensured to be positioned right above the gravity center of the bearing seat 3, so that the stress is uniform, and the bearing seat 3 is prevented from being skewed.

As shown in fig. 1 and 2, the lifting tool for the bearing seat dismounting process fully considers the appearance structure of the bearing seat 3, designs a reasonable integrated structure of the lifting hook 1 and the lifting ring 2, and replaces the previous procedure of iron wire binding lifting. When the bearing seat 3 is dismounted, the tool is directly used for hoisting, so that the dismounting work is simpler, the efficiency is obviously improved, the safety risk is reduced, the labor intensity is greatly reduced, and the cost is also saved.

The lifting tool for the bearing seat dismounting process is adopted, the bearing seat 3 used in the prior art does not need to be replaced, the lifting bearing seat 3 can be directly fixed, the shaking degree of the bearing seat 3 in the assembly process is greatly reduced through production test, the operation is simple, the fixing is firm, the accidental injury or scalding caused by slipping and falling of the bearing seat 3 of the cup of a worker is effectively avoided, and the safety coefficient is improved.

When in use, as shown in fig. 2, the bearing seat 3 can be lifted through the hanging ring 2 by directly inserting the hanging hook 1 into the bolt hole 4 of the bearing seat 3 when the bearing seat 3 is disassembled and assembled.

This lifting means that bearing frame dismouting process was used, simple structure, convenient to use has replaced current loaded down with trivial details iron wire process of binding, has alleviateed workman's intensity of labour, has improved bearing frame 3 dismouting efficiency.

The tool is reliable and durable, the replacement and maintenance cost of parts is low, after the tool is used, the disassembly and assembly work is simpler and more convenient, the efficiency of disassembling and assembling the bearing seat 3 is obviously improved, the safety risk is reduced, and the safety coefficient is improved.
