Abstract

the solution relates to the device for the front drilling in mechanized deep mines down both for drilling drills, so for borehole drilling using fluid váloe. The essence is that that it consists of a chassis (1) on which it is placed adjustable stand (2) in which it is through guides (32) and sleeves (2?) a sliding frame (3) with flexible fluid is fixed by the roller (35) the feed trolley (34) with the drill is slidably mounted hammer (4). The device is mobile along the scraper conveyor (5) to which is anchored when drilling. The device can advantageously be used in quarries and tunnels.

Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to a machine for face drilling in mechanized machines. deep mines. both for irrigation wells and for firing work using a flexible fluid cylinder.

So far, frontal drilling has been carried out in mechanized coalfaces of underground mines, both for irrigation boreholes and for drilling boreholes by hand drills. Manual drilling, especially for firing work, is very physically demanding, lengthy, with a considerable daily outage of the mining machine's time. The drilling of irrigation wells is also time consuming and laborious, with considerable physical strain on the workers. In both drilling operations, the workers suffer from an occupational disease - vaseoneurosis - after some time. Especially in manual drilling in low seams, where the manual thrusting of the drills is carried out by workers in a horizontal position over the mechanisms in the face, the work is very laborious and time consuming. In the low seams, no machinery has so far been used due to the small space and mechanisms used such as scraper conveyors and the like.

These disadvantages are reduced to a minimum by a machine for face boring in mechanized faces using a flexible fluid cylinder according to the invention, which consists of a chassis which is provided with movable rollers and detent plates on which an adjustable stand is rotatably mounted. the collar, which is located on the column, is rotatably attached to the guide of the sliding frame, on whose guides between the crossbars there is a slidingly mounted feed trolley equipped with thrust rollers through which a flexible fluid cylinder with a pressure fluid inlet and outlet passes. The flexible fluid cylinder is anchored in the crossbars, with the drill hammer fixed on the feed carriage and the chassis anchored to the scraper conveyor with the locking plates.

The advantage of the device for face drilling in the mechanized faces according to the invention is its simplicity, light and powerful construction, the device is easy to operate, easy to transport to the drilling point along the entire length of the face. The equipment significantly increases drilling performance, thereby significantly reducing machine downtime, extracting physical drilling effort, and providing flexible fluid pressure. The operation of the facility is handled by a single worker effortlessly, adverse vibrational effects on the human organism and thus prevent the occurrence of occupational disease and early retirement. The simplicity of the equipment enables its production in common workshops of the mining company.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a plan view of FIG. 1, and FIG. 3 is a view of FIG. 2.

On the scraper conveyor 5 a chassis 1 is mounted on the movable pulleys 11, which can be anchored to the scraper conveyor 2 by means of the locking plates 12 by means of screws. On the chassis 1, an adjustable upright 2 with a vertical column 21 of a pipe is rotatably mounted, on which a guide 32 of a sliding frame 2 is fixed by a sleeve 22, which is anchored in steel rails 33 24 »provided with thrust rollers 341 on which the drill hammer 4 is rigidly fixed. for example, compressed air or pressurized water. The flexible fluid cylinder 35 j ^e formed, for example, firefighting streamline.

The chassis 1 with the sliding frame 2> on which the feed carriage 34 with the hammer drill 4 / is transported on a scraper conveyor 5 located on the eyelet 7 into the mining space, where it is necessary to drill into the oi

- perpendicular to the pillar 6 by loosening the sleeve 22 and sliding it to the required distance from the pillar 6. By rotating the sliding frame 2 around the guides 32 in the sleeve 22, set the desired bore height from the front and secure it with the sleeve 22. and connect them to the pressure air distribution and the device is ready to bore. The flexible fluid cylinder 35 is connected via a port 351 and a port 352 to a compressed air line - not drawn. Drilling hammer feed 4 to and from the bore is controlled from the operator's position by a control valve - not drawn, flexible fluid cylinder 35 ° Compressed air supplied

or the pressurized water at the inlet 351 fills the flexible fluid cylinder 35 * by increasing the pressure by means of the pressure rollers 341 the feed carriage 34 with the hammer drill 4 is pushed into the bore. The amount of thrust can be controlled by the amount of pressurized air - or water supplied via inlet 351 to the flexible fluid cylinder 22. · After the borehole, the compressed air control valve is switched - not drawn - to the second position. 352 to the other end of the flexible fluid cylinder 35 - the inlet 351 is in communication with the waste. By increasing the pressure and the amount of compressed air into the outlet 352, the feed carriage 24 moves away from the pillar 6 by means of the pressure rollers 341. Thus, the cycle is repeated for each borehole.

The machine for face boring in the mechanized faces according to the invention can be advantageously used in boreholes, tunnels and the like. .
