A new slip structure

Abstract

The invention discloses a novel slip structure, which comprises a slip body, a hoop plate and a hoop ring. The snare is set on the hoop plate. The slip body includes two slip plates. A clamping area is formed between the two slip plates. At least two arc-shaped pressure plates are arranged on the outer arc surface of the slip plate. There are three arc-shaped hoop plates, and at least two docking grooves are respectively provided on the inner arc surface of the arc-shaped hoop plate, and the docking grooves are in one-to-one correspondence with the arc-shaped pressure plates, and the arc-shaped pressure plates fall in the corresponding butt joint grooves. Adopting a new type of slip structure of the present invention, when the clamping force is applied, the stress acting on the pipeline is evenly distributed. The slips are evenly transmitted to the surface of the clamping pipe, avoiding the direct contact between the holding ribs and the slips, and effectively improving the clamping effect.

Description

Technical field [0001] The present invention relates to a clamping ferrule structure, and more particularly to a new type of ferrous structure. Background technique [0002] The push machine plays an important role in the pilot in the long distance and large-range level direction. During the push process, the pipe is needed to push, and the tension of the pipe is usually used by the tile. Hold. The traditional katri ribs are directly against the outer wall of the karma, and the tricks are tightened, and their maximum equivalent stress is less than the stress, so the structural strength is in line with the actual needs; Structure acting on the pipeline, the stress is too concentrated, and it is easy to rupture in the long-term working process, and the traditional KWW does not pass the stress to the pipe in the pipe. The surface is made such that most loads are in the vicinity of the ribs. To this end, there is a need for a structure that can be evenly distributed on the ferrule du...

Problems solved by technology

The traditional slip ribs are directly against the outer wall of the slips, and when the slips are subjected to the clamping force, the maximum equivalent stress is less than the allowable stress, so its structural strength meets the actual use requirements; but the When the structure acts on the pipeline, the stress is too concentrated, and it is very easy to crack at the position of the pin hole of the rib plate during the long-term work process, and the traditional slips do not transmit the stress to the pipeline evenly through the slips during the tightening process of the pipeline. surface, so that most of the load acts near the ribs
