Anti-collision method for pipe body movement, transmission and collecting processes

Abstract

The invention relates to a collision prevention method during processes such as pipe body movement, transportation and collection. An elastic collision prevention part is arranged at the opening end at the two sides of the pipe body; the elastic collision prevention part is fixed on the pipe body and can move along with the pipe body without falling off; the biggest overall size (D) is more than the outside dimension of the pipe body. The method of the invention can turn the collision of the pipe body into the collision between the elastic collision prevention parts during each process of thepipe body movement, transportation and collection; as the elastic collision prevention part is made by elastic material, the elastic collision prevention part can absorb the vibration and energy of collision between pipe bodies or the vibration and energy of the collision between pipe body and other articles, thus effectively protecting pipe body quality and preventing other side effects producedby the collision.

Description

technical field [0001] The invention relates to a pipe body anti-collision method, in particular to a vibration reduction and anti-collision method for pipe body movement, transmission, collection and other processes. Background technique [0002] Pipe fittings include metal pipe fittings and non-metal pipe fittings, which are widely used in modern society. The movement, transmission and collection of pipes inevitably collide with each other or with other objects. The impact often has adverse effects on the quality of the pipe body, such as defects such as deterioration of the surface of the pipe body, deformation and cracking. And metal pipe bodies also can produce very big noise when colliding with each other, cause environmental pollution to surrounding environment, also damage the health of operator. For example, steel pipes with a large output at present, including oil well pipes, petroleum pipes, boiler pipes, and various structural pipes, etc., frequently collide wi...

Problems solved by technology

[0007] Although the devices involved in the above patents can play a certain role in anti-collision and noise reduction, some of their structures use chain transmission, and some use mechanical structures such as gear meshing. The entire device is complex and huge, and the cost of construction and transformation is relatively high. It needs motor to drive, and it is difficult to maintain

Moreover, the above-mentioned device can only be used in the steel pipe conveying process, requires special equipment, and has a narrow scope of application

[0008] Chinese patents 200510025577.9 and 200520041259.7 disclose a method and device for using magnetic force to control the movement of the pipe body so as to reduce the impact of the pipe body. The structure of the device described in the patent is still very complicated, and it is only suitable for ferromagnetic pipe body. Anti-collision of non-metallic pipe body is not applicable
