Unequal-diameter pipe rotary conveying mechanism

Abstract

The invention relates to the technical field of pipeline conveying devices, and provides an unequal-diameter pipe rotary conveying mechanism. The mechanism comprises two columns of supporting assemblies arranged in parallel. The supporting assembly comprises a floating support and a supporting sleeve which are movably connected in a sleeved mode. A carrier roller used for supporting the pipe is arranged on the floating support. A preset included angle is formed between the central axis of the carrier roller and the central axis of the pipe. An air cylinder is arranged in the supporting sleeve.The bottom of the floating support abuts against a telescopic part of the air cylinder. The air cylinders of all the supporting assemblies are connected to an air pressure source. In this way, the air cylinder for supporting the floating support is arranged in the supporting sleeve, the air cylinders of all the supporting assemblies are connected to the same air pressure source, and pressure is uniformly provided by the air pressure source, so that the bearing capacity provided by the carrier roller of each supporting assembly is always stable and the same. When contact with the convex part of the pipe, a self-balancing and self-adjusting function is achieved, and the central axis of the pipe is always kept horizontal in the conveying process.

Description

technical field [0001] The invention belongs to the technical field of pipeline conveying devices, and in particular relates to a rotary conveying mechanism for unequal-diameter pipes. Background technique [0002] Forming a plastic layer such as polyethylene or polyurethane on the outside of the pipe is considered the best way to prevent corrosion. [0003] For ordinary pipes (equal diameter pipes) with regular shapes, the existing conveying equipment can keep the central axis of the pipe horizontal during the conveying process, so the winding protection is easy to realize. [0004] For unequal-diameter tubes like socket tubes (such as the structure disclosed in CN201820747877.0 patent), there are equal-diameter parts and unequal-diameter parts in the tube body (such as the socket part of the socket tube). When the existing conveying equipment touches the unequal diameter part (the part that is raised relative to the tube body), the tube will be lifted upwards. [0005] S...

AI Technical Summary

Problems solved by technology

[0005] Since the existing conveying equipment is mostly composed of multiple sets of conveying rollers, during the conveying process, the pipe will continue to jump, causing the central axis to be unable to maintain a level, so winding protection cannot be used, and only spraying protection can be used. The protection level is low and the effect is poor.

[0006] In summary, there are obviously inconveniences and defects in the actual use of the existing technology, so it is necessary to improve
