Description

Phi, /

The invention relates to the mechanization of sewage treatment works in coal mines, and more specifically to mechanized crepes for abrasive faces during the development of flat seams of flat fall.

The aim of the invention is to simplify the design and improve the performance of the fastening of the overlap of the mechanized support to the hydraulic post.

Figure 1 shows the mount. Overlap mechanized lining to the hydraulic post, general view; figure 2 is a view of And figure 1; on fig.Z - section bb in figure 2; Fig. L is a view In figure 1; on fig.Z - type G in figure 4.

The device for fixing the overlap of a mechanized support to a hydraulic post contains a support pint 1 fixed on the overlap 2 and resting on the support 3 hydrorests 4. On the supporting patch 1 on the side of the bottom sheet 5 overlap 2 there is an annular stop 6 with grooved contributions 7, placed transversely to the longitudinal axis of the overlap 2. Each grooved insert 7 consists of several identical parts, for example, two brackets 8 connected in the working position of the securing bolt 9 and a nut 10 or another fastening element, for example a connecting piece pezhnoy bracket (4 and 5).

For assembling the liner 7, the caldera of the box 8 has a thickening of one of the shelves, the BI of which has a hole for the connecting bolt. The second shelf of the bracket 8 can also be made thickened, but without a hole. This thickening is necessary to select a gap between the annular insert 6 and the hydraulic head (support 3), which provides the optimum angle of inclination of the overlap 2. Limiters 11 are installed on the annular support 6 on both sides of the brackets 8 (inserts consisting of two or more brackets) 11. Limiters 11 do not; the brackets 8 can move along the annular stop 6 in one direction or the other, keeping them transverse relative to the longitudinal axis of the overlap 2 position. The stops 11 are made in the form of cylindrical pins pressed into the holes of the ring stop 6. They can also be made in the form of bulges on the ring stop 6

by podshshavki or vyshtampovki with dimensions higher than the gap between the surface of the ring stop 6 and the shelf bracket 8.

The brackets MOJ1 should be assembled into a groove insert 7 (Figures 4 and 5) consisting of two brackets 8, in which the holes for their connection are made oval in the transverse direction, with the hole in the one bracket being right, and in the other left. The connecting element is also made in the form of a bracket 12, each shelf of which is matched in shape with a hole in the bracket 8 of the insert 7.

The assembly of the mount assembly to the hydraulic post is made in the following way.

An overlap with support pin 1 and ring stop 6 is mounted on the spherical support 3 of hydroresistance 4. Then, staples 8 grooved inserts 7 are installed in pairs (right and left) between constraints 11 and connected to them by fastening brackets 12. For this the fastening bracket 12 is inserted into the hole of the bracket 8 of the grooved liner 7 by a single shelf,

rotated 180 and inserted into the hole of the other bracket 8 of the grooved liner 7. Under the force of gravity of the shelf, the fastening bracket 12 is installed perpendicular to the oval holes of the brackets 8 of the grooved insert 7. In the same way, the second grooved plug 7 is removed and disassembled. This grooved liner 7 is reversed.

The device works in the same way.

During the operation of the lining section in lava under load, the overlap 2 of its supporting p 1 1 rests on the head 3 of the hydraulic posts 4 and the bracket 8 of the grooved inserts 7 placed on the ring stop 6. When unloading the sections of the support, the head 3 of the hydraulics 4 descends, and with it the overlap 2. In the event of a clamping overlap 2 between adjacent lining sections and the roof of the excavation, the head 3 of the hydraulic post 4 is lowered without overlap 2 until it contacts the conical part with the brackets 8 of the grooved shell (fig. 3, dashed lines). Upon further unloading of the section of the hydraulic post 4 through the staples 8 of the grooved liner 7 and

an annular abutment 6 pulls the overlap off to remove the overlap 2 from the head and frees it from closing 3 hydrocalls A is sufficiently separable. The overlap 2 lowers the thread of the staple 8 of the liner 7 and removes them together with the head 3 of the hydraulic posts 4. from the ring stop 6.
