When one end of the steel pipe slides to the position of the bearing plate 32 under the driving of the traction belt 45, the friction wheel 22 close to the end of the steel pipe is separated from the sliding rail 1 to be abutted by the separating assembly 5 corresponding to the bearing plate 32, and the traction belt 45 at the end loses power. The traction belt 45 corresponding to the other end of the steel pipe continues to pull the steel pipe to slide towards the pipe cutting machine under the action of the friction wheel 22 at the other end of the rack 2, when the other end of the steel pipe also presses the corresponding bearing plate 32 downwards, the traction belt 45 at the other end of the steel pipe 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 object carrier 3.

Since the two bearing plates 32 are arranged in an array in parallel with the longitudinal direction of the pipe cutting machine, the skew steel pipe is adjusted to a state of being parallel to the pipe cutting machine by asynchronous traction of the traction belts 45 at the two ends. The clamping assemblies at the two ends of the pipe cutting machine can clamp the two ends of the steel pipe simultaneously, the labor intensity of workers is reduced, the feeding speed of equipment is increased, the occurrence probability that the steel pipe is forcibly straightened by self-centering of the clamping assemblies in the prior art is reduced, the abrasion of the clamping assemblies is reduced, and the service life and the maintenance cost of the pipe cutting machine are prolonged.

When the friction wheel 22 moves upwards under the action of the separating assembly 5 and is separated from the sliding rail 1, the distance between the friction wheel 22 and the tension wheel 41 is reduced, the traction belt 45 is prone to falling and skewing, and is prone to deviation when rotating again, the tension spring 44 enables the two tension wheels 41 to keep the tension force of the traction belt 45 all the time in the process of being away from each other, the probability that the traction belt 45 and the friction wheel 22 are loosened and deviated is reduced, and the looseness of the traction belt 45 caused by aging in the daily operation process of the compensation equipment is facilitated.
The separating assembly 5 comprises a first connecting rod 51 connected to the frame 2 in a sliding manner, a vertical first guide sleeve is fixedly connected to the position, corresponding to the first connecting rod 51, of the frame 2, 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, the first connecting rod 51 is far away from one end of the ground and fixedly connected to the bearing plate 32, and the bearing plate 32 vertically slides along with the first connecting rod 51.

When the frame 2 slides to the position of the pipe cutting machine for feeding, the limiting rod 522 blocks the steel pipe from sliding out towards the pipe cutting machine in a translation mode. Therefore, the supporting rod 511 is pushed upwards by the slope change of the wedge 11, the supporting rod 511 drives the first connecting rod 51 to slide upwards, the bearing plate 32 upwards supports the steel pipe, the limitation of the limiting rod 522 on the steel pipe is removed, and the steel pipe can be clamped smoothly by the pipe cutting machine, and the carrier 3 can be smoothly separated from the steel pipe.
The implementation principle of the feeding device of the laser pipe cutting machine in the embodiment of the application is as follows: a worker places a steel pipe on one end, far away from the pipe cutting machine, of the carrier frame 3 through a crown block, pushes the rack 2 to slide towards the pipe cutting machine along the sliding rail 1, the friction wheel 22 rolls through friction with the sliding rail 1 to drive the traction belt 45 to rotate, and the traction belt 45 pushes the steel pipe to slide towards the pipe cutting machine through friction force.

Since the two bearing plates 32 are arranged in an array in parallel with the longitudinal direction of the pipe cutting machine, the skew steel pipe is adjusted to a state of being parallel to the pipe cutting machine by asynchronous traction of the traction belts 45 at the two ends.
When the frame 2 slides to the position of the pipe cutting machine for feeding, the limiting rod 522 blocks the steel pipe from sliding out towards the pipe cutting machine in a translation mode. Therefore, the supporting rod 511 is pushed upwards by the slope change of the wedge 11, the supporting rod 511 drives the first connecting rod 51 to slide upwards, the bearing plate 32 upwards supports the steel pipe, the limitation of the limiting rod 522 on the steel pipe is removed, and the steel pipe can be clamped smoothly by the pipe cutting machine, and the carrier 3 can be smoothly separated from the steel pipe.
