Claims

[Claims for Utility Model Registration] 1. An inspection device 1b for inspecting the inside of the existing piping 5 is attached to the tip of a long body 3 equipped with a transmission means for transmitting inspection information of the inspection device 1b, and the long body 3 is A support member 6 that is an in-pipe inspection device that inspects the inside of the pipe 5 while being sequentially inserted into the pipe 5, and that comes into contact with the inner surface 4 of the pipe 5 to hold the inspection device 1b in a position near the pipe axis position. , the elongated body 3
In addition to providing multiple along the circumferential direction on the tip side,
This apparatus for inspecting inside a pipe is provided with an operating section 7 that can freely change and adjust the position of the contact point A of the support member 6 on the inner surface of the pipe in the radial direction of the pipe. 2. The support member 6 is made of a spring wire rod, the operation section 7 operates one end of each of the support members 6 to approach and separate from the other end, and the in-pipe contact point A is the operation section 7. The intermediate portion in the longitudinal direction of the support member 6 moves outward in the radial direction of the tube while being bent by moving one end of the support member 6 closer to the other end in the operation of step 7. The pipe inspection device described.
