Description

-In Avtorekom Listing No. 20058, metal-manhole fastening without racks for openings, carried out in coal, is described. In this mount, for underframing the ceiling, the excavations were made, at an angle to the horizon, boreholes, in which there were wood-grouse with heads, I pushed 14Im with forks with swivels and from the hole of the middle bolts serving to attach the beam. , .1 The proposed modification of a Mine Fixation. In several is a further development of the main invention.

In FIG. Figures 1-7 depict the variation of binder, described mainly by its author, CBJH, No. 20058. ..- f

In the lateral walls of the excavation (Fig. 1), it is possible to drill one electric drill or a hammer-hole of a well, 40-45 mm in diameter, up to a depth of -30-50 cm, above the depth of -30-50 cm.,

Wooden corks (wedges) are driven into the boreholes of the well, and in them, windmill grouse /, due to which the wooden corks burst; 11. rough surface; all the irregularities in them. . „

Heads of wood grouses end in a hook. Composite metal bars 5 or 5 (Fig. 3), having strong ears i at one end, are put on these. or 7. The length of the runway is several centimeters less than the width of the excavation.

The shifts may be extracted either from old air duct pipes or channels, a look at what happens at the mine.

Before putting the crossbar on the grouse hook, the collar 4 is put on the crossbar, which is intended to fasten the crossbeams at the ends with the simplest thrust. To eliminate movement, you can drive wooden wedges into the gaps of the clamp.

The metal adres are placed on top of the puffs and split, as usual;

 FIG. 1-3 / shows the options for tubular and channel shafts. Drilling wells is fast, installation is also, therefore, the total time required to mount is insignificant.

The width of the roll can vary from / to l, 8 I, with the i-length of the crossbar. At the maximum span, the distance Ft of the sides, development to

closest clasps; and the distance between the clamps is equal to UZ /.

Each individual part of the mount is completely accessible to one person ..

Variants, iso. B. 1-3, are convenient for use for single-track workings with flat and inclined occurrence in strong and medium strength coal seams or rocks, and for any strength of the roof.

 The use of these options is convenient for workings with their subsequent expansion, i.e., when double-track workings are carried out by complicated tamping.

With the expansion of production, the wood-grouse is exposed to smashing sides and, thus, easily removed. ,

It would not be possible to avoid the introduction of pipes into the wells (because). that it is impossible to precisely drill wells; the hinge joint for this reason is oblate (the river. The clogging of wood-grouse in a wooden plug eliminates its rotation.

The mounting variant of FIG. 4 and 5 are intended .. for a two-track pattern: a botok with strong or weak side walls and any drop. They are also suitable for single track excursions with weak ones, since the roof pressure is transmitted to the side shifts on the strut and most prevents them from sliding. The bearing surface for sticks in weak rocks can be extended with wooden linings.

The distinctive features of these options are as follows: the corners | s are curved and can be and riveted on kerchiefs from the channel bar; the end, inserted in the drilling of the first well to a depth of 30-40 cm, is given a circular cross-section along the diameter of the well; before inserting the bracket into the well, a goma- is put on it; t «to 3, which has a small gap in height W width. When the brackets are installed, a crossbar / 2 from a channel of any / length is laid on them. At the ends of the crossbar, 12 ives of the clamp / 5, imb | bc is otverts-and for a smooth pin or bolt

The clamps move onto the ends of the channel and are secured with pins or

bolted. You can push the clamps. failure. and then there is no need. pin x. Ignoring the deviation of the wells from the direction or changing the angle HaKVjOHaHe causes osolon. Worst of all, it may be in the installation, is that the iHumytik is pushed only at the end of the bar. And it cannot be further advanced; but this does not reflect on the mount. V

The brackets of the brackets (serves to support the ventilation pipes / 4. During the boil-out, the pieces are very frequent, are knocked out or broken, lines, /, Here, the impact does not threaten anything - it can only deflect at a certain angle. Taking this circumstance into account, it is better immediately for wells to mark the sites of laying along the length of the development so that the end is located in the recess on the wall of the working.

The fastening dimensions allow it to be used in drifts and crosscuts from 2.0 to 3 wide. For larger prelets the size of the brackets is 0, the treasures should be different.

The mounting options of FIG. b and 7 are different from the above described tech, that on the brackets 8 there are hook 9, s tree shaft from the channel is replaced by a chain / O.

In some cases, sometimes not on a grid on one of the side walls of the v1, to have a crown, a combination of the first and second variants is possible (Fig. 7). An eyelet is made at one end of the bar, and this end is put on the hook of a wood grouse, inserted into a wooden plug inserted into the well, and the other end of the bar lies on the bracket 9 and is fixed with homomigo / 3. ,

The use of the proposed options (Figs. 1-7) retains all the advantages of fastenings without braces, and in addition, makes it possible to apply the second variant (Fig. 4) with weak sides and a weak roof of the excavation.

 The subject matter of the invention.

.one. Modification of fastening according to clauses 1, 2, 3 and 4 of the author. certificate number 20058; characterized by the fact that the captive wood-grouse is hooked (Fig. 1 and 3) for hooking the ears 2

or 7 parts of tubular 5 or channel 5 shifting, fastened with ties 4 ..:. 2. Modification of the fastener according to claim 1, characterized in that Hto for two-way excavations and for workings with weak lateral rocks instead of rjiy khariy brackets (9 (. 4) used as supports for the crossbar 72, fastened with brackets / ties) / 3 .3. The change in the dyeing according to claim 2, characterized in that the brackets (fig. 6) are equipped with hooks 9, with the crossbar being replaced by a chain 10.

4. Video change attachment on PP. 1 and 2, characterized by the use of a 5-luhar 1 (Fig. 7) with a crossbar 12, equipped with a pin 2 at one end and resting on the other end with a bracket 8 fastened with a clamp 13.
