目前,主要的拉管设备不能适应管材拉拔生产工艺的高水平。对现代拉管机的要求是,大大提高以最大压缩率拉拔的速度,以及缩短辅助工序所占时间。本文研究链式拉管机拉拔时间缩短的可能性。在过渡过程与工作时间最短的条件下高速拉拔时,常常出现很大的动负荷。因此,设计高速拉管机时,对其参数与主传动功率的
At present, the main pipe pulling equipment can not meet the high level of pipe drawing production process. The requirement for modern pipe jacking machines is to greatly increase the rate of drawing at maximum compression and to shorten the time taken for auxiliary processes. This article studies the possibility of shortening the drawing time of a chain-type pipe-pulling machine. In the transition process and the shortest working hours under the conditions of high-speed drawing, often a lot of dynamic load. Therefore, the design of high-speed pipe pulling machine, its parameters and the main drive power
