When it is necessary to inspect the steel pipe head, first adjust the position of the adjustment seat 103 in advance according to the size of the steel pipe head, hoist the steel pipe head and place it on the bottom rotating support part to support the steel pipe head, then fix the steel pipe head through the side rotating clamping part and drive the steel pipe head to rotate, and then move the trolley frame 101 to the steel pipe head inspection position through the walking drive assembly; turn on the inspection, and the steel pipe head rotates under the action of the side rotating clamping part to meet the inspection positioning; after the inspection is completed, start the walking drive assembly again, exit the inspection position to reach the loading and unloading position, and hoist the lower head to complete an operation process. There is no need for staff to load and unload materials at the inspection equipment, thereby automatically completing the inspection of the steel pipe head and improving the inspection efficiency.

[0023] Secondly, the clamping fixed frame 104 is fixedly connected to the adjusting seat 103, the fixed clamping roller 106 is rotatably set on the clamping fixed frame 104, the cylinder 108 is fixedly installed on the adjusting seat 103, the clamping movable frame 105 is fixedly connected to the output end of the cylinder 108, the clamping movable frame 105 is slidably connected to the adjusting seat 103, and the movable clamping roller 107 is movably set on the clamping movable frame 105. The clamping fixed frame 104 is used to install the fixed clamping roller 106, and the clamping movable frame 105 is used to install the movable clamping roller 107. Both the movable clamping roller 107 and the fixed clamping roller 106 can be driven by a motor to realize rotation. The cylinder 108 is used to push the clamping movable frame 105 so that the position of the clamping movable frame 105 can be moved, thereby adjusting the distance between the movable clamping roller 107 and the fixed clamping roller 106. When it is necessary to fix the steel pipe head, the end of the steel pipe head is placed between the fixed clamping roller 106 and the movable clamping roller 107, and the cylinder 108 drives the movable clamping roller 107 to move closer to the fixed clamping roller 106. The fixed clamping roller 106 is moved in the direction of the fixed clamping roller 106, so that the inner and outer sides of the steel pipe head are respectively held by the fixed clamping roller 106 and the movable clamping roller 107, and the two head rotating components cooperate with each other to fix the steel pipe head. When the steel pipe head needs to be rotated, a driving structure such as a cylinder or a motor can be used to drive the fixed clamping roller 106 and the movable clamping roller 107, so that the fixed clamping roller 106 and the movable clamping roller 107 rotate in opposite directions. Since the inner and outer sides of the steel pipe head are respectively held by the fixed clamping roller 106 and the movable clamping roller 107, the fixed clamping roller 106 and the movable clamping roller 107 can drive the steel pipe head to rotate when they rotate in opposite directions.
