Detailed Description
The technical solution of the present invention will be further described below with reference to the accompanying drawings, but the present invention is not limited to these embodiments.

When the level detection system 4 detects that the walking system 1 is not level, the level detection system 4 sends a detection result to the control system 2, and the control system 2 performs level adjustment on the walking system 1 according to the detection result, so that the distance of the pipeline can be measured more accurately by the measurement system 3.
In this embodiment, the traveling system 1 includes four traveling wheels 11, the four traveling wheels are respectively installed two by two on two sides of the chassis 12, and each traveling wheel 11 is connected with a driving unit 13 for respectively driving the traveling wheels 11 to roll. Meanwhile, each driving unit 13 is connected with the control system 2, and the control system 2 can adjust the output of the driving units 13 to adjust the rotating speed of the travelling wheels 11. A lighting system 14 for illumination is also mounted at the front end of the chassis 12.
In the present embodiment, the level detection system 4 includes a gravity detection sensor for determining whether the traveling system 1 is level based on the detected data. In this embodiment, the horizontal detection may be realized by another horizontal detection sensor instead of the gravity detection sensor, and the embodiment is not limited thereto. The gravity detection sensor calculates the offset angle of the traveling system 1 according to the detected data, and when the offset angle is 0, namely the traveling system 1 keeps horizontal, the output of the driving unit 13 is not adjusted; when the angle of the offset is greater than 0, the output of the driving unit 13 is adjusted. In one embodiment, the two front road wheels of the traveling system 1 are lower than the two rear road wheels, that is, the traveling system 1 is inclined downward in the forward direction, in this case, the control system 2 decreases the output of the driving units 13 of the two front road wheels to reduce the speed thereof, and increases the output of the driving units 13 of the two rear road wheels to accelerate the same according to the angle of the downward inclination, so as to realize the horizontal adjustment of the traveling system 1 after a plurality of detections and adjustments. For the inclination state of the walking system 1 occurring in other situations, the horizontal adjustment can be performed according to the same principle, and therefore, the detailed description is omitted in this embodiment. By controlling the running system 1 to run horizontally, the measuring system 3 can run as straight as possible, so that the measured distance is closest to the actual length of the pipeline.
In the embodiment, the measuring system 3 comprises a distance measuring code disc 31 and an adaptive wheel 32 coaxially connected with the distance measuring code disc 31, wherein the distance measuring code disc 31 and the adaptive wheel 32 are connected with the walking system through an adaptive rod 33. The distance measuring coded disc 31 is coaxially connected with the adaptive wheel 32, the distance measuring coded disc 31 transmits a signal to the control system 2 according to the rotating angle, and the control system 2 calculates the length of the pipeline according to the angle signal and the wheel diameter of the adaptive wheel 32.
In this embodiment, the adaptive rod 33 is connected with the traveling system through the elastic member 34, and the adaptive rod 33 adjusts the height according to the pipe diameter of the pipeline, so that the adaptive wheel 32 is attached to the pipe wall, and the distance measuring precision is prevented from being influenced by sliding. Specifically, the elastic member 34 is a torsion spring, and one end of the adaptive rod 33 is hinged to the traveling system through the torsion spring. It should be noted that the elastic member 34 may be another member to realize the close contact between the adaptive wheel 32 and the pipe wall.
Further, the adaptive wheel 32 is made of a rubber material. The adaptive wheel 32 is made of rubber materials, and the surface friction degree is high, so that the distance measurement precision is prevented from being influenced by the sliding of the pipe wall.
Various modifications, additions and substitutions for the specific embodiments described herein may be made by those skilled in the art without departing from the spirit of the invention or exceeding the scope of the invention as defined in the accompanying claims.
