Description

Positioning and stabilization device for very ei tau s.-ja u

The innovation relates to a positioning and stabilizing device for support frames for walking supports in the mining industry with at least two consecutive stamps connected by trailing arms, with the front and rear supports being supported by a steel runner, which consists of a base plate, two on the side thereon and at right angles to it arranged side plates _r stiffening elements as well as on the front sides arranged runner plates and is equipped with the spacing of the front and rear stamp adapted holding devices for positioning the stamp, and the fastening elements for the stamp for the purpose of underground installation and removal of the steel runner are detachable.

The striding support used in mining generally consists of support frames combined to form support frames, whereby an extension frame usually two arranged one behind the other Stamp are assigned, which are usually articulated underpinning a one-part or multi-part hanging cap, the stamp at the same time be positioned by the hanging cap in the hanging area. Wear the Stamp mostly so-called stamp feet, which also mostly are articulated with the stamps. Link springs are often used to connect the stamps in the lying area arranged between the front and rear stamps of an expansion frame. The one mentioned at the beginning, from the DT-Gbm 7 128 287 known positioning and stabilization device is provided for extension frames, the two of which are arranged one behind the other Stamp wear stamp feet.

The innovation is based on the task of positioning the aforementioned positioning and stabilizing device in such a way writer to develop that the stamp is reliable even then can be positioned and stabilized if they do not have set feet. and the steel runner for bridging the unevenness of the lying plane the maximum punch load capacity can absorb without permanent deformation.

According to the invention, this object is achieved by the features forming the indicator ties claim 1. Using öer new positioning and holding device according to the invention the punch feet can be dispensed with without impairing stability. Installation and remodeling are carried out at the same time facilitated. The box profile-like design of the steel runner ensures that it has a flexural strength that utilizes the maximum load-bearing capacity of the punches currently in use without permanent deformation.

According to another embodiment of the innovation, in the case of thin seams, a sufficient insertion dimension of the inner stamp to ensure the steel runner corresponding to the characterizing part of claim 2 Features are trained. In this way, almost the entire free height between the patient and the extension canopy used as insertion path if necessary. An advantageous further development of the innovation is laid down in claim 3.

The innovation is explained in more detail below in an example using the drawing. Show it:

In Fig. 1 and 2 is between hanging wall (15) and lying (16)! Hines Strebes a walking frame. 1 .' from expansion frame; Each extension frame consists of a front (10) and a rear punch (11), on which a cap (14) rests against the hanging wall (15) and which are connected in the area of the horizontal (16) via trailing arms (13). The trailing arm springs (13) are each connected to the stamp (10, 11) via a fastening plate (18). The stamps (10, 11) are the | Pig in the example. 1 underpinned by a steel runner (21. The runner (2) has the effect that recesses (17) in the horizontal (16) can be easily bridged. Such recesses (17) can be removed from walking frames (1) without the steel runner ( 2), as shown in Fig. 2, can only be overcome with great difficulty, even if (floating punches (10, 11) are equipped with comparatively large punch feet (12). The front punch u / i (12) is in the example in Fig . 2 within the recess (17) and the associated Stem- \ pel (10) has assumed a bank inclined position. the trailing arms · (13) are thereby claimed very strong. This stress f may increase up to the breaking point when the Stempeifuß ( 12) sticks around the edge of the recess (17) when you move on. Similar difficulties occur with soft lying down (16), but these can also be avoided if the front punch (10) and rear punch (11) over the runner (2) on the Lying people (16) are reliably positioned and closed are stabilized at the same time, so that they always maintain an essentially banking position.

In FIGS. 3 to 5 details of the runner (2) are shown. The steel runner (2) according to this example is box-shaped and consists of a base plate (20) and from a cover plate (29) and side plates (21) arranged thereon at right angles. It has curved ends Kufenble-cne (22) on. Mittiy is the steel runner (2) with ftin longitudinal bolt (27). It also has two cross crucibles (28). At the crossing points of the cross bar (28) with the longitudinal bar (27) there are recesses (3) in the cover plate (29) provided as a support for the front punch (10) or rear punch (11). On the stamps (10, 11) are on the side Balttnasen (50) attached, which are in pairs of strips (51) Guides formed on the side plates (21), which have a widening (210) in these areas, are guided. A securing plate (52) fastened by a detachable fastening element (26) holds the stamp (10) or (11) on the Runner (2). On the cover plate (29) there are four holding tabs connected to one another in pairs via cross bars (61) (60) attached for the trailing arm springs (13) (Fig. 1). To increase the rigidity of the runner (2), the cover plate (29) arched in the central area (290) and the longitudinal bar (27) designed with a corresponding elevation (270). the Flexural rigidity is significantly higher than the maximum punch load capacity.

According to another embodiment, the steel runner (2), as shown in FIGS. 6 to 3, can have a reinforced base plate

(200) be equipped on which the side plates (21) with widening (210) for attaching the strips (51) and locking plate (52) for the purpose of guiding and holding the retaining lugs (50) on the stamps (10, 11) are attached. A shortened one The cover plate (290) is reinforced by a shortened longitudinal bar (270) and an inclined cross bar (280). As another Reinforced skid plates (220) are provided across the board. The recess (30) as a shell-like support for the stamp (10, 11) is made directly in the reinforced grand plate (200), so that the stamp (10, 11) practically the lying
