By setting the limit column 315, the stability effect of the segment hanger plate 302 during movement can be further increased, so that it can move more smoothly.

[0028] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4The telescopic ends of the two electric telescopic rods 303 are fixedly connected with the electric vacuum suction cup 304. Five cameras 306 are arranged above the support plate 1. The bottom surface of one camera 306 is fixedly connected to the upper surface of the support plate 1, and the upper surfaces of the other four cameras 306 are fixedly connected to the bottom surface of the frame 301.

[0032] Working principle: When in use, the staff first transports the device to a suitable position for use, and then turns on the power of the electric telescopic rod 303, the electric vacuum suction cup 304, the laser ranging sensor 305, the camera 306, the contact sensor 310, the first forward and reverse motor 313, the rotating motor 318 and the second forward and reverse motor 319, so that they can be in a stable power-on state. When it is necessary to collect and detect the image of the pipe segment, the staff turns on the electric telescopic rod 303, the electric vacuum suction cup 304 and the laser ranging sensor 305. After the electric telescopic rod 303 is turned on, it can drive the electric vacuum suction cup 304 to descend. The electric vacuum suction cup 304 can use the vacuum pump to generate negative pressure, so that an adsorption force is generated between the adsorption cup and the pipe segment, thereby adsorbing the pipe segment on the electric vacuum suction cup 304 for fixation. Then the laser ranging sensor 305 can calculate the distance by measuring the time required for the laser to be emitted from the sensor to be reflected back by the target object and received by the sensor. When the distance exceeds the set range, the first forward and reverse motor 313 will be controlled to be turned on. The first forward and reverse motor 313 can drive the threaded rod 314 to rotate when it is turned on, so as to drive the pipe segment hanging plate 302 and the pipe segment to move. After moving to a suitable position, the laser ranging sensor 305 turns off the first forward and reverse motor 313, and at the same time turns on the camera 306 to shoot the side and bottom of the pipe segment. When the acquisition is completed, the pipe segment is transferred to the support frame 309 through the electric telescopic rod 303, and the electric vacuum suction cup 304 is turned off at the same time, so that the pipe segment can fall on the surface of the support frame 309. When the pipe segment is on the support frame 309, the contact sensor 310 will be triggered. After the contact sensor 310 is turned on, it can control the camera 306 to collect images of the bottom of the pipe segment again. Finally, the second forward and reverse motor 319 is turned on. After the second forward and reverse motor 319 is turned on, it can drive the gear 320 to rotate, so as to remove the pipe segment and start the next round of detection.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
