SU386142A1 - MACHINE FOR EXTRACTING COAL IN STRETCHES, CROSSBARS AND STORE DEPOSITS ON LAYERS - Google Patents

Description

The invention relates to equipments for the mechanization of excavation with carbon-ground methods, in particular, can be used for excavating coal in drifts, subsections and store ledges on steeply-falling beds. Machines for excavating coal in drifts, glades and store ledges on steep dip beds are known, including drive, screw actuator, rotator and feed mechanism. The proposed machine differs from the known ones in that the screw actuator is located parallel to the drive and is connected to it by a rotary turret, which is hinged on the bed of the rotator by means of a vertical axis. This embodiment increases the efficiency of the machine and provides the excavation of coal from the soil drift. FIG. 1 shows the scheme of the proposed machine; in fig. 2 - the proposed machine, bat, iy kind; in fig. 3 is the same, section A-A in FIG. 2. The machine consists of a screw actuator /, a drive 2, a feed mechanism 3, sections of a ramp type 4 and a control panel, allowing remote control of the machine. The executive body is made in the form of a screw with teeth. The length of a speck should discolor the coal consumption in the drift for a length not less than the length of the cords drilled in the rock for the purpose of otpalki. In order to reduce overall dimensions during transportation, the auger is made of two parts. The actuator is driven by an air motor (or electric motor) 5 through a gearbox 6 and gears 7, 8 and 9. The air motor and gearbox are rigidly mounted on a rotatable turret 10 equipped with axles //, in which the steering arm 12 of the actuator is installed. The axis 13 of the rotation of the scenes coincides with the axis of the machine. Together with the executive body, the arm rotates around the horizontal axis I-I with the rocker jack 14, which is hinged on the swiveling turret and the wings 15 and 16. The gears 7, S and 9 are mounted in the turn gear. The rotary turret 10, together with the knots mounted on it, is fixed by a sharp on the bed 17 of the rotator by means of the vertical axis 18. The rotary turret together with the knots mounted on it can be turned around the vertical axis 18 in the horizontal plane at an angle of 90 ° or more connected hingedly to bed 17 and turret 10 axes 20 and 21. On the bed there is a fixed skid support 22, which does not allow the machine to squeeze it into the developed npocTpaECTBO.

The machine works in the following way.

With the aid of the feed mechanism 3, the machine is installed along the seam directly at the bottom of the drift. After installation, the actuator / stand 4 and the feed mechanism is fed through the developed fixed space into the upper part of the magazine ledge at idle. When the top of the bench is reached, the upward flow of the machine stops; destroys it.

In order to reduce the radius of curvature of the slab, in the process of reversal of the rezush; his organ in the pillar, the machine gradually moves up to the bottom. In addition, when feeding the machine to the upper part of the store ledge, the auger also clears the radius of the bottom.

The support ski 22 excludes the exit of the executive body “3 slabs, leaning on the support built in the worked-out space. When the executive body reaches the horizontal position, it is fed down

to the drift with the dismantling of the rod and produces coal excavation along the entire thickness of the formation to the very base of the drift. Repulsed coal from the slaughter is produced by an auger actuator, and then, by the space developed, by gravity into the carriage.

Adjustment of the actuator for reservoir power is carried out using a hydraulic jack 14, pumping the rocker 12 in the axles //. After the end of the coal extraction cycle at the bottom of the shchrek, the spring is placed on the rails and retracted deep into the drift road, making room for drilling, digging and harvesting the rock.

Subject invention

A coal excavation machine in drifts, clearances and store ledges on steep seams, including a drive, a screw actuator, a swivel device and a feed mechanism, which in order to increase the efficiency and ensure coal excavation from the drift soil

the screw actuator is located parallel to the drive and is connected to it by a rotary turret, which is hinged on the bed of the rotator by means of a vertical axis.
