In-pipe maintenance device and maintenance method thereof

Abstract

The invention discloses a pipe internal maintenance device and a maintenance method thereof. The pipe internal maintenance device comprises a visual cleaning nozzle, a fixed adjusting module and a monitoring power module arranged in a pipe body; the fixed adjusting module comprises an expansion fixed mechanism, a channel frame and a channel frame adjusting mechanism; a side branch pipe is arrangedon the wall of the pipe body; under driving by the monitoring power module, the fixed adjusting module can move in the pipe body; in an appointed area, the expansion fixed mechanism is opened to expand on the inner wall of the pipe body; through action of the channel frame adjusting mechanism, the channel frame is aligned to an orifice of the side branch pipe; and under the effect of driving power, the visual cleaning nozzle enters the side branch pipe and reaches a maintenance end of the side branch pipe. The pipe internal maintenance device is high in stability and adjusting efficiency, andcan effectively solve the equipment fixation and adjustment under working conditions to guarantee smooth accessing of the visual cleaning nozzle in the orifice of the side branch pipe to finish corresponding cleaning or video checking work so as to realize needed maintenance work.

Description

technical field [0001] The invention relates to the field of pipeline robots, in particular to an in-pipe maintenance device and a maintenance method thereof. Background technique [0002] Some annular pipes have small side branches distributed in the circumferential direction, such as figure 1 As shown, according to the needs of maintenance, the end of the branch pipe needs to be repaired, and there are some passing obstacles inside the annular pipe, so it is necessary to develop a special pipeline robot to complete the repair work. In this example, visual cleaning is used as an example for maintenance. The base material of the annular pipe is 316 stainless steel, and there are multiple measuring branch pipes evenly distributed in the circumferential direction. The length of the measuring branch pipes in the pipe is 1 / 3 of the inner diameter of the annular pipe, such as figure 2 As shown, a great obstacle is set for the movement of the robot, and at the same time, it incr...

AI Technical Summary

Problems solved by technology

For the convenience of movement, the circumferential size of the robot must be smaller than 2 / 3 of the inner diameter of the annular pipe, but this brings a lot of challenges to the design of the fixing and adjusting mechanism of the robot at the side branch pipe
