Rapid lifting device of angle steel straightening roll

Abstract

The invention relates to a rapid lifting device of an angle steel straightening roll. The rapid lifting device of the angle steel straightening roll comprises a round outer ring, lifting lugs, V-shaped baffles, vertical plates, pin holes A, pins B, pins A and pin holes; the opened round outer ring is connected with a to-be-lifted angle steel straightening roll in a sleeving manner; and three lifting lugs and four V-shaped baffles are fixed on the outer wall and the inner wall of the round outer ring correspondingly. Two mutually parallel vertical plates are arranged in the opening position ofthe round outer ring, and the two vertical plates extend outwards from the opening of the round outer ring. The pin holes A are formed in the centers of the two vertical plates; and the pins A are inserted into the pin holes A. The rapid lifting device of the angle steel straightening roll is simple to manufacture, adopts few materials, can realize rapid lifting of straightening rolls with different size and different number on an angle steel rolling line, and is simple to adjust and rapid in change. The lifting lugs are uniformly distributed on the round outer ring by 120 degrees; and when the straightening rolls are rapidly lifted, the balance stability is high, and safety and rapidness are realized.

Description

technical field [0001] The invention belongs to the field of mechanical processing, in particular to a quick hoisting device for angle steel straightening rollers. Background technique [0002] In the rolling production of angle steel, the straightening roller is a key component for straightening the rolled angle steel. After the angle steel comes out of the last finishing mill, there is a relatively obvious bend, and the straightening rollers produce continuous longitudinal and transverse elastic deformation and plastic deformation in the length and width directions of the profile, so as to achieve the purpose of straightening. In the production of modern iron and steel enterprises, due to the high-speed and high-efficiency production process requirements, higher requirements are put forward for straightening rollers. During use, they need to be replaced in time according to the wear situation. Allows quick replacement. Due to the special shape of the angle steel straight...

AI Technical Summary

Problems solved by technology

Due to the special shape of the angle steel straightening roller, the width-to-diameter ratio b / D<0.2, it is a disc member, and its pass is V-shaped. It is already very difficult to hoist by traditional methods, and it is impossible to achieve rapid hoisting.
