Abstract

This invention relates to mining machines used in mining and mining. The goal is to increase the safety of working the inclined workings. The hearth machine includes a body 2 with an executive body 3 and a chassis 1. On the frame 4 of the chassis 1, front and rear cutting bodies 7, 8 are installed, which can be made in the form of bars, discs or drills. Each of them is connected to the drive 13 and the hydraulic cylinder (HZ) 14 rotation. On the frame 4 of the undercarriage 1 with the possibility of longitudinal movement of HZ 6, a slider 5 is mounted, on which the rear cutting member 8 is located. Before the mining machine begins to work, the cutting bodies 7, 8 are inserted into the soil, ensure the machine is held and increase its stability and inclined workings. In the case of moving the machine in inclined workings, the cutting body 7 rises to the upper position, while the cutting body 8 fixed to the slider 5 remains in the lower position. The movement of the machine occurs by simultaneously turning on the movement mechanism and the HZ 6. Then the position of the cutting bodies 7, 8 is changed and the cutting body 8, which is in the upper position, is pulled to the frame 4 of the HZ 6 and lowered again to the lower position. 3 hp f-ly, 4 ill. i (L

The invention relates to the field of mining equipment, in particular to mining and mining machines, equipped with devices for fixing the machines in the workings.

The purpose of the invention is to increase the safety of work in inclined workings.

FIG. 1 shows a horn maschine with cutting elements in the form of bars; in fig. 2 - the same, in the form of disks; in fig. 3 - the same; in the form of a Boer; in fig. 4 - a forge machine in a sloping development.

The mining machine includes a running gear 1, a housing 2 and an executive body 3. The running gear of a mining machine has a frame 4 on which at least one slider 5 is mounted (installation of sliders on both sides of the frame is possible) connected to the frame by means of a power drive, for example cylinder 6, providing longitudinal movement of the slide relative to the frame. Cutting elements with rotational drives and their displacements in a vertical plane are installed on the frame, while cutting elements are installed in the front and rear parts of the chassis, on each side can be installed both one cutting element located on the central longitudinal axis of the machine, and two arranged symmetrically about the longitudinal axis, and, moreover, the cutting element (or a pair of elements) is mounted on one of the sides on the slider 5, and the second on the frame 4.

The cutting elements can be made in several versions: in the form of cutting bars 7 and 8 (Fig. 1), cutting disks 9 and 10 (Fig. 2) and vertical drills 11 and 12 (Fig. 3). Each of the cutting bars 7 and 8 (Fig. 1) is connected to a power drive 13 mounted on the frame and a turn hydraulic cylinder 14.

When the machine is working in horizontal development, the hydraulic cylinders 14 of the rotation are installed in such a way that they rotate the bars in opposite directions (either towards each other or, on the contrary, as shown by the arrows in Fig. 1).

When working in inclined workings, the hydraulic cylinders 14 of the rotation is installed so that provide the rotation of the bars in one direction (Fig. 4). The cutting discs 9 and 10 (Fig. 2) are equipped with a rotational drive 15 and a vertical movement actuator 16, allowing the discs to be embedded in the soil.

Vertical storms 11 and 12 (Fig. 3) are provided with rotational and vertical displacement drives 17 and 18, respectively, which ensure that these elements are drilled into the soil.

The device works as follows.

In the transport position, the cutting elements are located in the upper lift and

shifted between themselves the position (Fig. 1 - 3, position I.

Before starting work, the cutting elements are turned on and lowered to the lower position (Fig. 1-3, position II), inserted into the soil and forming a slit in it, and remain during operation of the mash in these slots, the walls of which perceive reactive forces from the executive bodies of the machine, ensuring retention and increase in the stability of the machine in a plane parallel to its supporting surface when operating in both horizontal and inclined conditions (Fig. 4).

If it is necessary to move the machine in inclined workings to ensure that it does not slip, the cutting element 7 fixed on one side of the frame (Fig. 4) rises to the upper position, while the cutting element 8 fixed on the slider remains in the lowered (lower) position and by simultaneously switching on the mechanism for moving the maschine and the hydraulic cylinder 6, the maschine is displaced when the cutting element 8 remains in the same position. ezhuschy element 8 is raised into the upper position, Ack pulled to the frame 6 and cylinder again lowered to the lower position (dotted line). As a result, the machine moves for a predetermined distance L and is fixed again.

Cutting elements - bars or discs mounted on the frame and slider, if necessary, can be used for tillage, for example, to form drainage grooves. To do this, one of the elements is turned into a vertical position, fixed in that position, and the machine is driven.
