Description

Technical Field

[0001] The utility model relates to the technical field of metallurgy, in particular to a special push-pull hook for hoisting a rolling roller. Background Art

[0002] At present, in the process of changing the rolls in the bar and wire workshop, a lifting tool is needed to lift the rolling rod from the lathe, or to lift it from other places on the lathe. The usual practice is to tie the wire rope to one end of the roll, and then use a hook to hook the wire rope to lift it. Although this method is simple, the wire rope is time-consuming and labor-intensive to tie, and it is not easy to tie it tightly, and it will slip, which brings safety hazards; and the roll will swing when assembling, and it is difficult to put the roll on the trolley track. If you grab the wire rope by hand or hold the roll to assist in assembly, it will seriously affect safety and be an illegal operation.

[0003] The existing Chinese patent application CN201473194U discloses a special tool for lifting a roller with a threaded center hole. The patent disclosure can firmly fix the fixing rod and the roller, and then tie the wire rope to the lifting rod to lift the roller. The structure is simple and easy to use. When nuts are fixed at both ends of the lifting rod, the wire rope can be prevented from falling off the lifting rod, making the lifting safer.

[0004] The above-mentioned patent only solves the safety issues of hoisting and lifting of the rollers. No tools are used to assist in the assembly of the rollers. Therefore, there are still safety hazards in the assembly by hand-gripping the wire rope or hand-supporting the rollers. Utility Model Content

[0011] Preferably, the lengths of the first limiting segment and the second limiting segment are equal, and the lengths of the first limiting segment and the second limiting segment are 140 mm respectively.

[0012] Preferably, the lengths of the pulling section and the pushing section are equal, and the lengths of the pulling section and the pushing section are 20 mm respectively.

[0013] Preferably, the diameter of the threaded steel bar is 8-12 mm.

[0014] Preferably, the length of the threaded steel bar is 1760 mm.

[0015] Preferably, the handle is in the shape of a ring, and the circumference of the ring-shaped handle is 300 mm.

[0016] Preferably, an end point of the second limiting segment is on the same transverse line as the pulling segment.
