Abstract

The invention discloses a repairing device for a cracked oil pipeline. The repairing device for the cracked oil pipeline comprises an embracing hoop body. The embracing hoop comprises an arc-shaped plate. Lapping blocks are arranged at the upper and lower ends of the arc-shaped plate. Installation holes are formed in the lapping blocks, and the opening directions of the installation holes are parallel to the radial direction of the arc-shaped plate. Two arc-shaped grooves which are parallel to each other are formed in the inner wall of the arc-shaped plate. The two arc-shaped grooves which areparallel to each other are adjacent to the two end surfaces of the arc-shaped plate separately. Sealing strips are arranged in the two arc-shaped grooves which are parallel to each other, long-strip-shaped grooves are formed in the lapping blocks of the arc-shaped plate, the long-strip-shaped grooves are located at the lapping surfaces of the lapping blocks, and sealing strips are arranged in thelong-strip-shaped grooves. The embracing hoop capable of blocking leaks of an oil transportation pipeline is convenient to use, low in cost, and suitable for application and popularization.

Description

technical field [0001] The invention relates to the technical field of oil pipelines, in particular to a repair device for broken oil pipelines. Background technique [0002] Pipeline transportation is mostly used for oil transportation. Oil transportation pipeline plays a very important role in oil transportation. Pipeline transportation is a more economical and reasonable transportation method for crude oil transportation. In the process of oil transportation, a large number of oil pipelines need to be used. These oil pipelines are usually laid off the ground. During oil transportation, once the oil pipeline is subjected to external force impact or internal pressure of the pipeline, the oil pipeline may be damaged. As a result, oil spills are caused, resources are wasted, and the environment is polluted, resulting in unnecessary losses. The cracks of the oil pipeline cannot be repaired directly by welding, and it is very troublesome to weld and repair the crack after the ...
