Description

Large hollow roller heat treatment hoisting tool

technical field

The utility model relates to a large-scale hollow roller heat treatment hoisting tool.

Background technique

The roll body of a large roll is usually made of a hollow tube, and the roll body needs to be heat treated in the production process. The traditional operation method is to use a chain or a wire rope to hoist the roll body from the processing machine to the heat treatment place. The slipping phenomenon causes the surface of the processed roller body to wear, and in severe cases, the workpiece will fall, which not only damages the workpiece, but also adversely affects safe production.

SUMMARY OF THE INVENTION

The technical problem to be solved by the utility model is: in order to overcome the deficiencies in the prior art, the utility model provides a large-scale hollow roller heat treatment hoisting tool to ensure the safety of hoisting and the surface quality of the roller body from wear.

The technical solution adopted by the utility model to solve the technical problem is as follows: a large-scale hollow roller heat treatment hoisting tool, comprising two chains, the upper end of the chain is connected to the hoisting equipment, and the lower end of the chain is connected with a clamping block, so The clamping blocks are clamped on the cylinder walls at both ends of the roller.

Specifically, the clamping block includes a hanging block and a right-angle support block hooked on the hanging block. The bottom end of the hanging block has a right-angle notch, and the horizontal part of the right-angle support block and the right-angle notch form a rectangular slot that is clamped into the roller wall. and the upper end of the hanging block is provided with an oblique groove for connecting the bottom end of the chain.

Further, two hooks are fixed at the upper and lower intervals on the back of the hanging block, a square groove is arranged in the middle of the vertical part of the right-angle support block, and two hanging rods arranged at an upper and lower interval are arranged in the square groove and can be hung on the hooks. , the two ends of the hanging rod are fixed with the side wall of the square groove.

The beneficial effects of the utility model are: the utility model utilizes the clamping block to be inserted into the roller, and the large-scale hollow roller can be hoisted conveniently by using a chain or a steel wire rope, the hoisting will not slide, the surface quality of the roller will not be affected, and the roller will not be easy to hoist. Drop, safe and fast operation, save time and effort, improve the safety of lifting.

Detailed ways

The present utility model will now be described in further detail in conjunction with the accompanying drawings. These drawings are all simplified schematic diagrams, and only illustrate the basic structure of the present invention in a schematic manner, so they only show the structures related to the present invention.

As shown in FIG. 1, a large-scale hollow roller heat treatment hoisting tool includes two chains 1. The upper end of the chain 1 is connected to the hoisting equipment, and the lower end of the chain 1 is connected with a clamping block 2. The clamping block 2 It is stuck on the cylinder walls at both ends of the roller 3 .

Specifically, the clamping block 2 includes a hanging block 4 and a right-angle support block 5 hung on the hanging block 4. The bottom end of the hanging block 4 has a right-angle notch, and the horizontal part of the right-angle support block 5 and the right-angle notch form a snap-in roller The rectangular slot 6 on the wall of the cylinder 3, the upper end of the hanging block 4 has an oblique groove 7 for connecting the bottom end of the chain 1, the end of the oblique groove 7 is arc-shaped, and the lower part of the chain 1 is connected to the circle of the oblique groove 7. The arc-shaped end makes it easy to hoist the roller 3 to the heat treatment site by using the hoisting equipment.

Two hooks 8 are fixed at the upper and lower intervals on the back of the hanging block 4 , the vertical part of the right-angle support block 5 has a square groove in the middle, and in the square groove, there are two hanging hooks that can be hung on the hooks 8 arranged at an upper and lower interval. Rod 9, the two ends of the hanging rod 9 are fixed with the side walls of the square groove, so that when the rollers 3 of different thicknesses are hoisted, the upper and lower hooks 8 are selected by the hanging rod 9, and the opening of the rectangular slot 6 can be easily realized. adjustment to meet the requirements of use.

The utility model utilizes one end of the clamping block 2 to be clamped into the roller 3, and one end to connect the chain 1 (here the chain 1 can also be replaced by a steel wire rope), so that the large-scale hollow roller 3 can be hoisted conveniently, and the sliding phenomenon will not occur during hoisting, and the roller 3. The surface quality is not affected, and the roller 3 is not easy to fall off. The operation is safe and fast, saving time and effort, and improving the safety of the roller 3 when it is hoisted.

Taking the above ideal embodiment according to the present invention as inspiration, through the above description, relevant staff can make various changes and modifications without departing from the technical idea of the present invention. The technical scope of the present utility model is not limited to the content in the description, and its technical scope must be determined according to the scope of the claims.
