Auxiliary mechanism for bending petroleum pipeline

Abstract

The invention discloses an auxiliary mechanism for bending a petroleum pipeline, and belongs to the technical field of petroleum pipeline processing. The auxiliary mechanism includes a pipeline bending device, an auxiliary table, a polishing device, an auxiliary device, a fixing device, and a limiting device. The polishing device includes an adjustment assembly and a polishing assembly. The auxiliary device is arranged at the front end of the polishing device, the fixing device includes a driving assembly and a fixing assembly, the fixing assembly is installed at the front end of the polishingdevice, the driving assembly is arranged on the adjusting assembly, and the driving assembly is matched with the fixing assembly. The limiting device includes a restricting assembly and a plurality of limiting assemblies. The limiting assemblies are distributed at the front of the polishing assembly at equally intervals. The restricting assembly is installed above the adjusting assembly and the restricting assembly is matched with all the limiting assemblies. The deformation of the pipeline bending positions at the time of bending the pipeline can be reduced or even prevented through the auxiliary device, the pipeline bending position can be polished by the polishing device, and the quality of the pipeline is improved.

Description

technical field [0001] The invention relates to the technical field of oil pipeline processing, in particular to an auxiliary mechanism for oil pipeline bending. Background technique [0002] Pipeline transportation is the most commonly used transportation method for petroleum. For some connections, in addition to using the connector to connect and turn the pipeline, sometimes it is necessary to bend the pipeline to match the installation. [0003] In the existing pipe bending machines, the bending arm is rotated to drive the pipe to bend around the bending point. However, such a bending machine still has the following disadvantages when bending oil pipelines. First, when the pipe is bent, it is easy to cause the deformation of the pipe, that is, the distance between the pipe and the two sides in contact with the bending arm and the bending point will decrease, but the distance between the upper and lower sides will increase, which will generally lead to The cross-section ...
