Step transition roller

Abstract

The invention discloses a stepped transitional roller and belongs to the field of transport mechanism. The stepped transitional roller comprises a bearing, a dead axle fixed on the bearing and two bearing seat plates fixed on both ends of the dead axle; wherein, the bearing seat plates can rotate around the dead axle, two dynamic rollers are arranged on different levels between the two bearing seat plates capable of moving along with the bearing seat plates; the bearing seat plates are further provided with reset springs. The roller can also be arranged on the front side of an ordinary V-shaped roller on a production line; the rotation of the two dynamic rollers around the dead axle can lift a rougher end of a pipe to a certain height, the end of the pipe is stably transported to the ordinary V-shaped roller, thus avoiding the impact of the rougher end of the pipe on the ordinary V-shaped roller, reducing the vibration between the pipe and the roller, overcoming the damage of the pipeand other parts caused by impact, as well as improving the transport efficiency and prolonging the service life of the roller.

Description

technical field [0001] The invention relates to a transmission machine used in pipe material processing, in particular to a step transition roller. Background technique [0002] The oil and gas industry needs to use a large number of pipes, including oil pipelines, oil production pipes and various drill pipes, etc. These pipes are used in various fields of oil and gas exploration and transportation. In order to meet different needs, it is necessary to further process the cast pipe. In the process of processing, in order to improve work efficiency, pipes are usually processed step by step by means of an assembly line. [0003] V-shaped roller is an axial transmission component used in pipe processing and repair lines. The V-shaped wheels widely used at present are all single-wheel structures, and the positions are fixed. Except that the roller itself can rotate around the axis, other parts cannot move. This structure is more suitable for conveying pipes with exactly the sa...

AI Technical Summary

Problems solved by technology

The V-shaped wheels that are widely used at present are all single-wheel structures, and their positions are fixed. Except for the roller itself, which can rotate around its axis, other parts cannot move.

This structure is more suitable for conveying pipes with exactly the same outer diameter, but because most of the pipes have a structure with large outer diameters at both ends and a small outer diameter in the middle, when using the existing V-shaped rollers to transport pipes, the thicker end of the pipe The bottom surface of the bottom is lower than the upper surface of the outer circle of the V-shaped roller, so that when the pipe is transferred from one roller to the other, the drill pipe end will impact the surface of the front roller, resulting in damage to the rubber layer on the surface of the V-shaped roller. It may even jam the pipe and cause the transmission operation to be interrupted; in addition, the impact will also cause damage to the end of the pipe and other parts on the assembly line

In addition, when the weight of the pipe being conveyed is heavy or the conveying speed of the pipe is high, the degree of damage to the roller and the conveyed pipe will be more serious

The above reasons lead to a serious decrease in the service life of the V-shaped roller, and also reduce the transmission and processing efficiency of the pipe
