Description

one

The invention relates to the mining industry, namely to the means of mechanization of manual and labor-intensive operations associated with excavation of the settled rock mass when re-consolidating or restoring horizontal mine workings.

The aim of the invention is to mechanize the process of excavating the settled rock mass along the perimeter of the mine.

In Fig.1 schematically depicts the described device, side view; figure 2 is the same, top view; figure 3 is a view of And figure 1.

A device for excavating the settled rock mass includes a platform. I with a chassis, a turning mechanism 2, a moving frame 3, an executive one. body 4, two-stage drive 5 and 6. The executive body is made in the form of a telescopic sliding casing 7 with a disk working body 8 and a shaft 9. The device includes rods 10 hydraulic cylinders 11, shaft 12, hydraulic jack 13, electric motor 14, sliding shaft 15, hydraulic jack 16, support legs 1 7, hydraulic jack 18, bending conveyor 19, reduction gear 20, electric motor 21, drive of oil station 22 and intake).

The assembly of the device for removing the mass of the roofing surface is as follows.

On the external casing 7, having the shape of a prism, a diagonal disk working unit 8 is installed. The cutting discs are rigidly mounted on the shaft 9. Four bearings are mounted on the shaft 9, two of them in the middle part.

The shaft 9 passes through the openings of the casing 7. For the bearing, they are mounted on the casing 7 from the outside, one of which is covered by a cover. At the other end of the shaft 9, a worm wheel is mounted, driven by a screw.

The worm gear together with the screw represents the drive 6 of the second stage, which is mounted on the outside of the casing 7.

A shaft 9 with two bearings in the middle part is mounted on the rods of 10 hydraulic cylinders 11. The screw is rigidly connected to a shaft 15 with internal splines on the other

shaft and driven by the drive 5 of the first stage. The latter is driven by an electric motor 14 mounted in the lower part of the casing 7. The assembled actuator 4 is rigidly mounted on the shaft 12, which can be freely rotated on the carriage of the turning mechanism 2 by means of a hydraulic jack 13 at the required 1st angle relative to the horizontal axis.

The hydraulic cylinders 1I are installed inside the casing 7.

The turning mechanism 2 is mounted on the frame 3, which is located in the guides of the platform 1 from the inside. Frame 3 can be moved along. platform 1 with the help of hydraulic jacks together with the turning mechanism 2 and the executive body A.

The actuator 4, together with the rotation mechanism 2, can be rotated around a vertical axis in both directions with restriction. Restrictions are due to the cable of the electric motor i-heater 14. At the ends of platform I, four supporting legs 17 are installed, driven by hydraulic jacks 18. From below platform 1, a conveyor 19 is installed for driem and. loads of broken rock mass to transporting means. On the platform 1, a drive of the conveyor 19, an electric motor 21 and an oil station 22 are installed. In the upper part of the actuator 4, an intake device 23 is installed. The running part of the platform is individually driven with an electric motor. Platform 1 also has a control panel and a safety canopy for the driver.

The device works as follows.

A device is fed into the mine where the lining should be replaced with a choice of the settled rock mass. The running gear is switched on and the device is pressed in place under the settled mountain mass. The paws 17 are extended. The executive body 4 is placed in a working position.

The conveyor 18 is turned on, to which the empty trolley is fed. The engine 14 and the first stage drive 5 are turned on. The movement from the actuator 5 of the first stage through the sliding shaft 15 with internal gearing is transmitted to the actuator 6 of the second stage, then

the movement is transmitted to the shaft 9 of the working body 8. The executive body is advanced by means of hydraulic cylinders 11 and selects (beats off) the settled rock mass along the perimeter of working between the supports. The mass, the pad between the discs, is broken, passes inside the casing 7 and falls on the conveyor I9, which overloads it to the transporting means. Additional grinding is repulsed mass gets under the stress on the shaft 12 inside the casing 7.

To excavate the rock mass around the working perimeter, the executive body 4 performs a swinging movement in both directions relative to the platform 1 at a three-side angle using the hydraulic cylinder 13. B on: the cloned position repulsed the mass also falls inside the casing 7 and under the action of its own weight, taking into account the internal friction forces, gets onto the conveyor 19. In the absence of a free fall of the broken mass at large angles of inclination of the actuator 4, we need frequent elevations of the actuator to rock mass packed inside the housing.

 The installation can provide the removal of the settled mass without moving the platform, i.e. from one installation for the length of development equal to the pitch of two supports. This is ensured by the fact that the mechanism 2. Turns on

frame 3, which is located on the inside in the guides of the platform 1. The frame 3 can be moved within the platform for a length,

5. The equal step of the two lining.

After sampling the settled mass and adjusting the surface of the mine to the desired state, the mine is fastened anew. The removal of the settled mass, depending on the mining and geological conditions, can be carried out between the frames without removing them.

First, the settled mass is removed on both sides of the lining, then lining

15 is removed and repeated by working the working body brings the surface to the required condition.

The device can also provide for the installation of support elements. For this, the 20th part of the working disks 8 is cut off for ease of transportation and possibility of use for the installation of lining elements, especially the tops. The support (upper) is placed on a horizontal (cut off) section of the working discs 8. In this case, the working discs 8 are mounted in a certain direction.

With the help of hydraulic cylinders 11 lining

30 rises to the roof. Then, the lower elements of the support are attached to the raised upper cushion. Two top plates with fasteners attached to them can be lifted simultaneously to the roof.
