Abstract

The invention relates to the mining industry and can be used for plow excavation of thin steep seams. The goal is to increase the reliability of work while simultaneously expanding the range of application in terms of stability of lateral rocks. The unit includes a base beam (BB) 1, lining sections 9 with air bellows (PB) 13, a plow actuator (SIO) 15 with a cutting head 16 and a roller 17 installed at its ends, a traction body and a drive. The securing sections 9 consist of a top 10, a base 8 and telescopic links forming partitions 12 between PB 13. Each section 9 is attached with BB 1, which has a socket and is designed as an I-beam. In this case, the SIO 15 is connected to the BB 1 by means of telescopic brackets 18 with rollers 19 and springs 20. The rollers 19 of the SIO 15 are installed with the ability to interact with sections 9 with PB 13 with the passing course of the SIO 15. The roller 15 SIO 15 is placed with the possibility of interacting with bottomhole formation In the initial position, BB 1 has no connection with the SIO 15. With the passing of the SIO 15, when its rollers 19 are inserted into the socket of BB 1, the support section 9 is moved from the PB 13 to the bottom with preliminary support. In the opposite direction, when the brackets are moved inside the SIO 15, the coal is dredged. If necessary, the BP 13 is provided for ventilation generation using a traction device. 6 Il.

The invention relates to the mining industry and can be used for plow excavation of thin steep seams.

The aim of the invention is to increase the reliability of the unit while at the same time expanding the range of application in terms of stability of lateral rocks.

FIG. 1 shows a unit for unmanned excavation of steep seams, a general view; in fig. 2 shows a section A-A in FIG. in fig. 3 - the position of the unit in the process of coal extraction, when one row

cylinders 31. The suspension device 3 is moved along a ventilation hole by an extension-root mechanism 32, which consists of movement cylinders 33 connecting the suspension device 3 with side skis 3 and transverse cylinders 35. A pneumatic support line 13 is attached to body 36.

The unit works as follows.

In the initial position, the base beam 1 has no kinematic connection with the plow actuator 15 and

pneumatic bolting issued for the Pro-15 it is located on an inclined plane 7

lactic on ventilation openings; in fig. 4 shows a section BB in FIG. 3; in fig. 5 shows a section B-B in FIG. one; in fig. 6 - section G-Y in FIG. one.

The unit for deserted steep seams consists of a base beam 1, made with an I-beam profile guide, the upper end of which is attached to a cylinder 2 mounted on a suspension device 3 located in a ventilation hole 4. The suspension device 3 is provided with transverse cylinders 5 and cylinders 6 for changing the inclination of the plane 7 of the suspension device 3.

The base beam 1 is attached to the base 8 of the lining section 9, consisting of the top 10 and telescopic links 11, which form partitions 12 between the rows of pneumatic ram 13. In turn, each section of the lining 9 is attached to the traction body 14. According to The base Oalka 1 can move the plow actuator 15, the body of which, on the one hand, has a cutting head 16, and the other, rollers 17, interacting with the face of the formation. The plow actuator, in the course of passing, is connected to the base beam 1 by means of telescopic brackets 18 with rollers 19 and springs 20.

For trouble-free interaction of the rollers 19 with the base beam 1, its upper end is designed as a socket 21. The plow body 15 moves — along the bottom 22 — by means of an actuator 23, a traction body 2k and a driving 25 and a bypass 26 stars.

The movement of the drive 23 along the transport excavation 27 is carried out by an extension-walking main mechanism 28, consisting of movement cylinders 29, side skis 30 and transverse

suspension device 3.

The coal excavation begins by moving the upper end of the base beam 1 with the bell 21 by the cylinder 2 along the inclined plane 7 of the suspension device 3 towards the bottom 22 before installing the bell 21 against the rollers 19 of the telescopic brackets 18 of the plow extraction body 15. Then using the drive 23 and the traction body 24, the plowing of the plow actuator 15 is carried out into the socket 21 of the base girder-1. With the passage of the plow actuator 15, the springs 20 are compressed and it moves to the bottom of the lining sections 9. The lining sections 9 are moved to the bottom with preliminary back-up.

In the lower part of the cleaning, the spring-mounted executive element 15 comes off the base beam 1. At the same time, the springs 20 expand and move the telescopic brackets 18 inside the plow control body 15, which leads to the formation of the necessary clearance between the rollers 19 and the base beam 1, the Plow control body 15 continues to move around the face without interacting with base beam 1.

In the opposite direction of the plow body 15, the coal is excavated by the cutting head 16. At this section, the lining 9, interconnected by the traction body 14, is in the unwrapped state of the memala of the lateral rocks and does not allow the collapsed lateral rocks to act on the plow body 15. After a thin reservoir has been excavated along the entire length of the sewage treatment, the inter-branch executive body 15 occupies the uppermost position, being on an inclined plane 7

suspension device 3, above the socket 21 of the base beam 1. The position of the inclined plane 7 is adjusted by cylinders 6. After each cycle, when the side skis are unraveled by side skis 3 and 3 cross-section cylinders 3 of the distance-walking mechanism 32, the suspension device 3 is moved to the bottom by cylinders 33 This pre-rolls the transverse cylinders 5 of the suspension device 3. At the transport development also when the lateral skis 30 are unraveled by cross-jacks 30, the drive 23 is shifted by cylinders 29 Spacer motion-walking mechanism 28.

20 interacting with the pneumatic bolting when passing the plow executive body, and the cutting group of the plow executive body is made in the form of a cutting head,

For the production, repair, and prophylaxis of pneumatic support, the latter 13 are supplied to the ventilation output with the help of a traction device 36. At the same time, the second row of pneumatic support lining 13 provides the necessary length of 25 which is placed at one of the pore ends of the lining sections 9 in order to prevent the hull of the plow executive of the collapsed rocks into the bottom-hole organ, and the roller is located on the space opposite the end of the body of the plow executive .
