The preset pressure value range can be set according to experience through work, and can also be determined through numerous tests.
In combination with the use of the pipeline detection equipment, if the pressure value indicated by the pressure information acquired by the pressure detection part 150 is greater than the preset pressure value range, the controller 160 immediately controls the telescopic support part 130 to contract so as to reduce the height of the carrying platform 140 close to one end of the telescopic support part 130 until the pressure value indicated by the pressure information is within the preset pressure value range; if the pressure value represented by the pressure information acquired by the pressure detection part 150 is smaller than the preset pressure value range, the controller 160 immediately controls the telescopic support part 130 to extend so as to raise the height of the carrying platform 140 close to one end of the telescopic support part 130 until the pressure value represented by the pressure information is within the preset pressure value range; if the pressure value indicated by the pressure information acquired by the pressure detector 150 is within the preset pressure value range, it indicates that the mounting platform 140 is in a horizontal state.

Wherein, the clamping driving piece can be an electric push rod, a servo motor, an electric cylinder and the like.
In the actual use process, the controller 160 controls the clamping driving member to operate to control the corresponding telescopic clamping member 180 to extend along the direction toward the carrying platform 141 until the telescopic clamping member abuts against the surface of the carrying platform 141, so as to clamp the carrying platform 140, and further ensure that the laser scanner on the carrying platform 141 can accurately and reliably perform the measurement.
Referring to fig. 1 again, in some embodiments, the controller 160 includes a first control module 161 and a second control module 162. The first control module 161 is used for controlling the telescopic support 130 to be telescopic along the second direction 20 according to the pressure information. The second control module 162 is configured to control the telescopic clamping member 180 to extend and retract along the third direction 30 according to the rotation angle information.
From this, through first control module 161 and second control module 162 control flexible support 130 and flexible holder 180 work respectively to automatically regulated carries on platform 140's levelness and guarantees its job stabilization nature, and then can realize the automatically regulated to laser scanner levelness in the measurement process, and guarantee that laser scanner is more stable in the measurement process.
