Description

MACHINE FOR TRAINING OF RISING DEVELOPMENTS

I

The invention relates to devices for mechanized penetration of rising workings in mines at the angle of incidence of the formation, which ensures the gravity of the destroyed coal or rock.

Machines are known for driving uphole workings from top to bottom along a pre-drilled well, including a housing, an actuator, a gearbox, and a drive chain connected to a drive mounted on a drift.

The proposed machine differs from the known ones in that the drive shaft of the actuator gearbox is made with two output ends on which sprockets are mounted, which interact with different branches of the drive chain.

This ensures the stability of the machine relative to its longitudinal axis.

FIG. 1 shows a diagram of the proposed machine; in fig. 2 is a diagram of the stroke of the drive chain of stars.

The machine includes an executive body}, gear 2 and drive winch 3, made on the drift. The driving branch 4 of the drive chain bends around the drive 5 and the deflecting 6 and 7 sprockets. Single branch 8 of the drive chain bends around asterisks 9 - //. Sprockets 5 and 10 are mounted on the drive shaft. The drive shaft is made of two parts 12 and / 5 connected by a coupling M, In the ventilation drift, a bypass unit 15 is fastened, and in the drive winch 3 there is a drive sprocket 16.

The machine works as follows.

The bypass unit 15 is secured in the right place and the drive winch 3 is installed. Simultaneously with the descent of the drill stand, the drilling machine that drilled the advance well passes the drive chain from the ventilation drift to the well and install the machine in the initial position. The drive chain is engaged with the drive sprocket 16 of the drive winch 3. The interaction of the chain with asterisks 5 vi 10 rotates both parts of the drive shaft 12 and 13. From the drive shaft through the gearbox 2, the rotation is transmitted to the actuator 1, which interacts with the face coal or rock. The machine is driven to the bottom by a component of the dead weight of the maschine, and due to the difference in tension between the drive and idler branches of the drive chain. In this case, the stability of the machine in the bottomhole is ensured by the fact that both parts of the drive shaft, by means of asterisks 5 and 10, interact with both branches of the 4 and 8 drive chains.

Destroyed coal or rock in a pre-drilled well rolls down.
