Description

one

The invention relates to mining, in particular to sinking-mining machines with a swept executive body.

A tunneling machine is known, which includes a movement mechanism, a housing on which an arrow-shaped actuator is installed with the possibility of relative movement, a norjiysKH mechanism and a thrusting mechanism with power jacks l.

The disadvantage of such a machine is the difficulty of obtaining a flat slab shape, especially in the workings of large width.

The closest technical solution to the described invention is a sinking machine, comprising a portal, a running gear, a thrust mechanism in the form of power jacks. a boom movable in the vertical and horizontal planes with a working body equipped with a percussion instrument. 2.

The disadvantage of the well-known machine is that the working tool produces a spherical face, which is especially noticeable with large width drifts. In these cases, permanent support can be erected only at a considerable distance from the bottom.

The aim of the inventions is to increase the technological capabilities of the downhole processing machine by improving the handling of the working member.

The goal is achieved by the fact that the boom is equipped with a bridge located on the portal with the possibility of movement, connected with the portal by means of guides with the possibility of movement perpendicular to the longitudinal axis of the machine, while the bridge is equipped with two rotary supports placed on the portal, one of which is fixed on the portal, and the other, located on the boom, has a sled mounted on the portal guides perpendicular to the longitudinal axis of the machine.

FIG. 1 shows the proposed mining machine; in fig. 2 - the same, top view (with shown dashed .line recurring sled and arrows); in fig. 3 - front view of the car; in fig. 4 shows another embodiment of a single-boom sinking-mining machine, top view; in fig. 5 is the same; the section along A-A in FIG. four; Fig. 6 shows another form of the machine, top view; in fig. 7 - forms

making machine with two arrows, top view.

The tunneling machine 1 has a portal 2 and a running gear 3. It is equipped with spacer elements 4 and power jacks 5, which are shown by a dash-dotted line in the position for .ko and in the working, fully extended position.

On the transverse trusses 6 and 7 of the portal 2, the bridge 8 moves in the direction of the longitudinal axis of the transverse trusses. The bridge 8 has an actuator 9 at its end facing the transverse truss 7. In addition, the bridge 8 is provided with an axle 10 on which the connecting part 11 of the boom 12 is pivotally mounted with the possibility of raising and lowering it. Using the working cylinders 13, the boom 12 can rotate around its longitudinal axis.

A percussion instrument 14 is pivotally mounted at the free end of the second boom 12. Between the sides of the portal 2 there is a tensioning chain 15, which serves as a drive for the crest 8.

On the transverse truss 6 there are slides: 16, having the possibility of movement in the longitudinal direction, which on their upper side carry the support 17 for the bridge 8. The other transverse truss 7 is provided in the middle with an axial hinge support 18, which carries the central sliding bearing 19. In the sliding bearing axially, the guide rod 20 slides, fixed with its end on the bridge 8. The bridge 8 is rotated around both the supports 17 and 18 of the rotation through hydraulic cylinders 21.

With the help of the mining tool 14, due to the appropriate installation of the bridge 8 and (or) the boom 12, the bottom of the chest can be made relatively even. As a result, you can install the mounting frame in the immediate vicinity of the chest slaughtered,
