The traction belt 45 at the other end of the corresponding steel pipe continuously pulls the steel pipe to slide towards the pipe cutting machine under the action of the friction wheel 22 at the other end of the frame 2, when the corresponding bearing plate 32 is pressed down by the other end of the steel pipe, the traction belt 45 at the other end of the steel pipe also loses power, and at the moment, the two ends of the steel pipe are respectively positioned on the bearing plates 32 at the two ends of the carrier 3. When the traction belt 45 at one end stops and the traction belt 45 at the other end continues to rotate, the steel pipe rotates by taking the bearing plate 32 at the end where the traction belt 45 stops as the circle center, and the rotation circle center of the steel pipe is basically stable in the process that the traction belt 45 at the other end drives the steel pipe to rotate due to the fact that the automation of the steel pipe is large. Since the two receiving plates 32 are arranged in parallel with the longitudinal direction of the pipe cutter in an array, the skewed steel pipe is adjusted to be parallel with the pipe cutter by asynchronous traction of the traction belts 45 at both ends. The clamping assemblies at two ends of the pipe cutting machine can clamp two ends of the steel pipe simultaneously, so that the labor intensity of workers is reduced, the feeding speed of equipment is improved, meanwhile, the probability of occurrence of forced centering of the steel pipe by self-centering of the clamping assemblies in the past is reduced, the abrasion of the clamping assemblies is reduced, and the service life and maintenance cost of the pipe cutting machine are prolonged.

When the friction wheel 22 moves upwards under the action of the separating assembly 5 to be separated from the sliding rail 1, the distance between the friction wheel 22 and the tensioning wheel 41 is reduced, the traction belt 45 is easy to fall off and incline, and is easy to deviate when rotating again, the tensioning spring 44 enables the two tensioning wheels 41 to always keep the tensioning force of the traction belt 45 in the process of being away from each other, the probability of loosening and deviation of the traction belt 45 and the friction wheel 22 is reduced, and the loosening of the traction belt 45 due to ageing in the daily operation process of the compensation equipment is also facilitated.
The separation assembly 5 comprises a first connecting rod 51 which is connected to the frame 2 in a sliding manner, a first guide sleeve which is arranged vertically is fixedly connected to the position of the frame 2 corresponding to the first connecting rod 51, the first connecting rod 51 is connected with the frame 2 in a sliding manner through the first guide sleeve, the first connecting rod 51 slides in the vertical direction, one end, far away from the ground, of the first connecting rod 51 is fixedly connected to the bearing plate 32, and the bearing plate 32 slides vertically along with the first connecting rod 51.

In the process that the first connecting rod 51 and the second connecting rod 52 are close to or far away from each other, the swinging rod 6 needs to stretch along with the change of the distance between the swinging rod 6 and the connecting position of the first connecting rod 51 and the second connecting rod 52, and the swinging rod 6 compensates the change of the length of the swinging rod 6 in the rotating process by utilizing the design that the sleeve 61 and the sliding rod 62 relatively slide, so that the running stability of equipment is improved.
And one end, far away from the ground, of the second connecting rod 52 is fixedly connected with a vertically arranged limiting rod 522, and when the second connecting rod 52 slides upwards, the limiting rod 522 moves to one end, close to the pipe cutting machine, of the carrier 3, and one side, far away from the pipe cutting machine, of the limiting rod 522 can be abutted against the steel pipe. When the second connecting rod 52 slides upwards, the limiting rod 522 moves to one end of the carrier 3 close to the pipe cutting machine, the probability that the steel pipe continuously slides to the pipe cutting machine and falls off from the carrier 3 is reduced, meanwhile, the limiting rod 522 improves the relative stability of the circle center in the process of rotating the steel pipe around the bearing plate 32 by limiting the sliding of the stop end of the steel pipe, and the probability that the length direction of the steel pipe is parallel to the length direction of the pipe cutting machine is improved.

Since the two receiving plates 32 are arranged in parallel with the longitudinal direction of the pipe cutter in an array, the skewed steel pipe is adjusted to be parallel with the pipe cutter by asynchronous traction of the traction belts 45 at both ends.
When the stand 2 slides to the pipe cutting machine position for feeding, the limiting rod 522 prevents the steel pipe from sliding out in a translational manner to the pipe cutting machine. Therefore, the supporting rod 511 is pushed upwards by means of the gradient change of the wedge 11, the supporting rod 511 drives the first connecting rod 51 to slide upwards, the bearing plate 32 supports the steel pipe upwards, the limit of the limiting rod 522 on the steel pipe is relieved, and the pipe cutting machine is convenient to stably and smoothly clamp the steel pipe and smoothly separate the carrier 3 from the steel pipe.
