Moving expansion element for intra-day mining operations,

The invention relates to a Ausbauelernent for underground Grubenbetrieb®ο It has long been known "in the long-fronts = mining of coal three rows of Binselstempeln to set by hand" and susätElioh® expansion Bocke at the Bruchkaate ₀ The Bina®lstempel wear caps ₉ among themselves articulated composite ® ^ so that you can adapt to the course of the hanging wall *

In the last year Lauf® © migratory expansion elements are designed for the face supports and have been applied successfully "Sin Such wandering Ausbaueletnent has a plurality of hydraulic punches, which are arranged on a base plate

Even with moving building elements there are generally three Rows of pit punches between the mining front and the

Broken edge used. has proven to be appropriate ο

In practice, it has SiOH in training d @ r Kappenkonstrmk - = functions as proven erforderlieh "reach a compromise between the rigidity of" having the cap constructions' need to be sufficiently stable and flexibility "to the adjustment of the cap constructions The course of the hanging wall enables this, when building with individual stones, this can be achieved by the fact that the individual caps are adapted to the course of the hanging wall by the operating staff during the setting process. When using moving expansion @ l © iaent @ n, on the other hand, the adapting of the caps to the course of the hanging wall must be carried out without the assistance of the operating personnel, and this has resulted in considerable difficulties

Satisfactory results have been obtained with such expansion parties erEielti, which have a rear main element ^ the four Has stamp and the hanging wall at the Brucbkante strong

whose Kapp® is pivotably attached to the main element _f so that it can easily be adapted to the course of the hanging wall and is supported by a single punch c

So far has one been in the practice of the aneicht _? and this was also required by numerous mining authorities that between one

It is also necessary that a Stempelraih © on Strebförd © r @ passes and behind this a passage for the Bedienungsper = personnel for driving of the longwall is "Dies® requirements could at migratory joinery only be satisfied by _f that DI® Ausbauelem @ nt @ structured to _s are dab in the longwall three rows extend stamp "

The invention is based on the object © ₉ ®inan wandering

Create expansion _? of the above requirements srfüllt while only two punch rows between d @ r working face and the Bruehkante having β Such expansion has the advantage ₉ that it has a much smaller slope ends = area support having as an expansion dtr three stamp rows so that its Ausbauelement® substantially can be less expensive than an extension with three rows of punches <,

The subject of the invention is a wandering expansion element for iint @ rtägig @ mining operations »in particular for the longwall construction ₈ whose caps are supported by hydraulic rams and which is characterized by the fact that the expansion element © ine has an I-shaped cap _s on its longitudinal direction in the face Sehenkel ein® in Ve rhi eb sr i along the other leg extending parallel fm Vorpfändkappe is articulated by a hydraulic ^ Grubenstempel.unterstützt is, "

The Alias construction element can have a base plate ₉ on which at least four pit _{stamps at the corners of a square 9 in} front of a rectangle, for example _Q, on a daily basis. The corners of a polygon are arranged at the corners of a polygon and a cap construction which in turn consists of a part »that rests stably on at least three stamps and another file, because on a stamp on 1 each gt and is pivotably connected to the first-mentioned rope« with the connection point behind the foremost punch of the named cap part is arranged "

In a preferred embodiment of the expansion element of the invention is the mar = caps supported by a stamp till can be swiveled with the fixed cap part at one point connected ρ that are far behind the foremost punch of the fixed · = the cap part lies gto

The expansion element according to the invention can have four stamps di @ are arranged at the corners of a rectangle ₉ during the

fixed cap part has the shape of an L »The other part of the cap is a straight cap» which is arranged parallel to the leg of the I-shaped cap part running in the direction of cutting and in the leg of the fixed part of the cap running in the longitudinal direction of the face is pivotably mounted ₉ so that the cap in its entirety has the outline of a rectangle ₉ from the delivery side on a S @ it @ a pre-pledging cap =

The words "stable" and "steady", used in conjunction with @ being used in © m the cap part®, do not exclude that this cap part can be inclined to a certain extent
