[0038] As a more detailed description of the present embodiment, the fine-tuning assembly 500 includes a left pressure screw 510 and a right pressure screw 520. The two groups of left pressure screws 510 are respectively threadedly inserted into the corresponding left side support column 240, and the lower ends of the left pressure screws 510 and the right pressure screws 520 are respectively correspondingly abutted against the surface of the corresponding outer support plate 221, and the two groups of right pressure screws 520 are respectively threadedly inserted into the corresponding right side support column 340, and the upper ends of the left pressure screws 510 and the right pressure screws 520 are fixed. There is a linkage wheel 530, and the four linkage wheels 530 are connected and driven by a linkage belt 531. The upper ends of the left pressure screw 510 and the right pressure screw 520 are sleeved with an upper turntable 540. An upper handle 541 is fixed to the side of the upper surface of the upper turntable 540. The lower part of the upper turntable 540 is respectively inserted and assembled with the upper ends of the left pressure screw 510 and the right pressure screw 520 through a limiting screw pin 543. A limiting clamp 542 is clamped in the center of the upper turntable 540, and the limiting clamp 542 is clamped in the middle of the upper turntable 540. The cross section of 542 is hexagonal, and two sets of limit clamps 542 are integrally arranged on the top of the left pressure screw 510 and the right pressure screw 520. The bottom of the left pressure screw 510 and the right pressure screw 520 are fixed with a downward pressure head 511, and the downward pressure head 511 is located on the upper surface of the outer pressure plate 221.

[0039] As a more detailed description of this embodiment, a locking moving wheel 130 is fixed to the bottom of the frame column 120, and a reinforcing rib frame 140 is supported and installed between two adjacent groups of frame columns 120, and the top of the reinforcing rib frame 140 is welded to the lower surface of the side of the upper frame 110, so as to strengthen the overall frame strength of the upper frame 110 without hindering the auxiliary operation below. At the same time, with the setting of the locking moving wheel 130, it is convenient to support and stop the movement of the transport frame 100.

[0040] Working principle: When it is necessary to clamp the pipe, the transport frame 100 is moved horizontally to the bottom of the pipe with the cooperation of the locking moving wheel 130. According to the length of the pipe, the transport frame 100 can be moved to the center of the pipe for a short pipe, so that the left clamping assembly 200 and the right clamping assembly 300 can be used to clamp and lift the pipe in the center, which is convenient for subsequent transportation. For a long pipe, a corresponding number of transport frames 100 are selected according to its transportation needs and moved to both ends and the middle for cooperation in lifting and moving transportation.

When clamping, first hold the upper grip 541 and rotate it. Under the cooperation of the limit clamp head 542 and the transmission of the linkage wheel 530 and the linkage belt 531, the rotation of one group is convenient for synchronously driving the other four groups, that is, the rotation of the upper turntable 540 on one side is convenient for synchronously driving the rotation of the left pressure screw 510 and the right pressure screw 520, so that the left pressure screw 510 and the right pressure screw 520 are in the corresponding The left side support column 240 and the right side support column 340 are connected by threads under cooperation, so that the left pressure screw 510 and the right pressure screw 520 are convenient to be pressed down synchronously, so that the left pressure screw 510 and the right pressure screw 520 are in contact with the outer support plate 221 under the cooperation of the downward pressure support head 511, so that the lower parts of the corresponding left lower clamping arm 220 and the right lower clamping arm 320 are synchronously contracted inwardly, thereby facilitating the preliminary micro-clamping and limiting of the pipeline, and then under the clamping of the lower clamping tooth plate 222, the lower part of the pipeline is preliminarily limited and clamped behind the lower ends of the left lower clamping arm 220 and the right lower clamping arm 320;

[0042] Furthermore, the servo motor 410 is driven to rotate, and the drive wheel 440 is driven to rotate synchronously with the cooperation of the drive belt 441 under the cooperation of the reducer 420 and the drive shaft 430. Under the support of the tray rotating frame 452, the support tray 451 is convenient for lifting the left drive wheel 450 and the right drive wheel 460. At the same time, when the left drive wheel 450 and the right drive wheel 460 rotate, they are conveniently supported by the tray rotating frame 452 and the corresponding annular grooves so as not to hinder their rotation, so that the left drive wheel 450 and the right drive wheel 460 cooperate with each other in the inner screw barrel 453. The left and right hanging studs 230 and 330 are lifted up by the threads, and the left and right hanging studs 230 and 330 will not rotate with the inner screw barrel 453 under the limitation of the lifting bottom plate 231, the upper slide rod 250 and the upper slide slot 251, so that the thread lifting operation is more convenient, so that the left clamping assembly 200 and the right clamping assembly 300 are easy to lift up, and when lifting up, the lower ends of the left and right support columns 240 and 340 are in contact with each other, so that the lower parts of the left and right lower clamping arms 220 and 320 continue to shrink inward, so that the pipe is lifted up while being clamped, making the operation more convenient and efficient;

[0043] Furthermore, after the pipe is lifted off the ground, with the cooperation of the locked moving wheel 130, the transport frame 100 can easily drive the lifted pipe to move with the cooperation of the left clamping assembly 200 and the right clamping assembly 300, thereby realizing the clamping, moving and transporting operation of the pipe.
