1.工作原理SR280R型入岩式旋挖钻机主要由钻杆1、随动架2、钻斗3、动力头4、加压缸5和底盘6组成。钻杆1上端与随动架2连接,下端与钻斗3连接,中间的动力头4用于将钻机输出的扭矩传递给钻杆1,从而驱动钻杆1旋转。加压缸5可对动力头4施加的压力,通过钻杆1作用在钻斗3上,以增火钻斗3的钻进力。旋挖钻机钻杆主要分为摩阻杆和机锁杆2种,本文所述SR280R型旋挖钻机配置的是机
1. Working principle SR280R type rock rotary drilling rig is mainly composed of drill pipe 1, follower frame 2, drill bucket 3, power head 4, pressure cylinder 5 and chassis 6. The upper end of the drill pipe 1 is connected with the follower frame 2, the lower end of the drill pipe 1 is connected with the drill bucket 3, and the middle power head 4 is used for transmitting the torque output by the drill to the drill pipe 1 to drive the drill pipe 1 to rotate. The pressure that the pressure cylinder 5 can apply to the power head 4 acts on the drilling bucket 3 through the drill rod 1 to increase the drilling force of the drilling bucket 3. Rotary drilling rig drill rod is divided into two types of friction rod and machine lock lever, SR280R type rotary drilling rig described in this configuration is the machine
