Problems solved by technology

The chain 220 in the chain drive mechanism 200 cannot be automatically tensioned, and the chain is prone to vibration during the working process, and even the phenomenon of tooth skipping occurs. When the chain 220 is subjected to a momentary large overload, the link head may be broken.

Abstract

The invention provides a feeding system which comprises a trolley and a chain transmission mechanism which drives the trolley to move. The feeding system further comprises a buffering device and a middle chain wheel device which is arranged at the bottom of the trolley, wherein the chain transmission mechanism comprises a transmission chain wheel and a chain which abuts against the transmission chain wheel and is partly engaged with teeth of the transmission chain wheel; one end of the chain is connected with one side, far from the middle chain wheel device and the buffering device, of the bottom of the trolley; and the other end of the chain rounds the middle chain wheel device and is then connected with one end of the buffering device. With the combination of the rail trolley and chain transmission, feeding of a greater-distance and heavier steel pipe is realized; an automatic tensioning mechanism is adopted for the chain transmission, so that the chain is located in a tensioned state all the time, and a chain joint is prevented from being pulled to be broken in case of instant high overload; and the rail trolley is supported by rollers on and below a rail, so that the overturn of the trolley caused by high stress during the feeding of the steel pipe is prevented.

Description

technical field [0001] The invention relates to the technical field of steel pipe rolling equipment, in particular to a feeding system. Background technique [0002] The task of the axial feeding system is to clamp the steel pipe to stand still on the supporting roller table, to feed and expand the diameter on the expanding head step by step, and then drag the steel pipe back to the unloading position. [0003] To accomplish this function, the axial feed system must accelerate or decelerate at a pre-set speed to precisely push the steel pipe forward. The axial feed system consists of several individual subsystems: lower frame, chain guide drive, steel tube clamps, axial feed control and feed shrink rollers. The steel pipe is moved out by the lifting roller table to the designated position and waits for the trolley. Then the steel pipe is clamped by the clamp on the trolley, and sent out by the trolley and the lifting roller together. The clamp releases the steel pipe, and...
