First, what is the structure of rock drill

Electric rock drill is an electric tool used for drilling in rock mass. That is, the drill pipe and drill bit are rotated by the motor through the variable speed mechanism, and are pushed manually or by other mechanical means to drill holes in the soft rock.

The rock drill is composed of a motor, a reducer box and a runway, and the motor and the reducer box are integrated into a main engine, which works on the runway through sprockets and chains.

The motor is a three-phase AC squirrel-cage self-fan-air-cooled asynchronous motor.

The reducer has three output shafts, one drives the drill pipe to rotate, and the other is two symmetrical worm shafts, which make the host slow forward on the runway through the single-head worm gear system and double-sided friction clutch, and make the host quickly return on the runway through the double-head right-handed worm gear system and double-sided friction clutch.


Second, what are the operation methods of rock drill

1. Determine the erection position of the drilling frame (self-made) according to the use occasion and the location of the drilling hole, install the chain on the main engine, and then install the main engine on the runway, and put the chain two

The end is connected to the runway, and the chain tie rod is adjusted, so that the chain obtains a certain tension, and the runway is fixed to the drill frame.

2, before drilling the hand wheel to the neutral position, no-load operation for five minutes, when the motor insulation is good, rock drilling without abnormal sound, and the spindle rotation direction and reducer

When the direction of the arrows is consistent, install the drill bit and drill pipe and connect the water source.
