Abstract

The invention discloses an in-pipeline working body transporting and positioning device, a transporting method and a positioning method. The in-pipeline working body transporting and positioning device comprises a first rubber stopper, a flexible pipe and a second rubber stopper. One end of the flexible pipe penetrates through the first rubber stopper and the second rubber stopper to be connectedwith a working body, and the other end of the flexible pipe is connected with a hydraulic pump. The outer wall of the part, between the first rubber stopper and the second rubber stopper, of the flexible pipe is provided with a pipe wall hole. A device for pipeline machining or overhauling can be fed into a pipeline. The working body can be successfully transported into the pipeline, drilling machining, overhauling, finishing and the like can be carried out in the pipeline, and the in-pipeline working body transporting and positioning device, the transporting method and the positioning methodare suitable for various types of straight pipes and elbow pipes.

Description

technical field

[0001] The invention belongs to the technical field of pipeline finishing, and relates to a transport and positioning device for a working body in a pipeline, and also relates to a transport method for a working body in a pipeline, and a positioning method for a transport and positioning device for a working body in a pipeline. Background technique

[0002] Pipes are common parts in production and life, including straight pipes and bent pipes. Due to the poor openness of the pipeline, it is very difficult to perform operations such as drilling, repairing, and finishing on the inner wall of the pipeline. For example, it is necessary to drill holes at specific positions inside the pipeline, or install sensors, or inspect the damage location inside the pipeline. This is still the case for straight pipes, but it is even more difficult to realize the above operations for bent pipes.

[0003] It is mainly manifested in two aspects, one is how to send the processin...
