MECHANIZED CABINET KIT

The subject of the invention is a set of a mechanized mining support intended for the exploitation of mining excavations, especially those working on soft ground.

The previously known set of mechanized mining support had handles attached to each canopy to guide the chain stabilizing individual sections of the support. This chain was led along the casing set under the outer lower part of the canopy. At the ends of the set and, if necessary, in any place of the casing, a yoke was placed to lock the chain to individual sections. Equipping the canopies with additional handles and a hanging chain under the canopies made it difficult for the crew to communicate on the wall, especially during the operation of the lower decks.

A mechanized mining support assembly according to the invention has in each section in at least one canopy an elongated through hole with a length most preferably equal to the stroke of the section shifter. In these openings a stabilizing chain is guided along the entire housing assembly. Each of these holes has a socket and a plug that allows locking the position of the stabilizing chain in relation to the individual sections of the set.

Such a location of the stabilization chain in the powered support set in no way limits the working space in the mining excavation. The chain stopper placed on the section allows it to be easily blocked in relation to individual sections.

The inventive powered support assembly is shown in an exemplary embodiment in the drawing, in which Fig. 1 shows a section of the support in a partial view, and Fig. 2 shows two sections in a partial side view and sectional view.

The individual sections of the casing in the canopies 1 are provided with through elongated holes 2. These openings are most preferably equal to the stroke of the section shifter. In the holes 2 a stabilizing chain 3 is guided over the entire length of the casing assembly. Near the hole 2

There is a socket 4 in which a plug 5 blocking the chain 3 is placed. Making a chain blockade 5 in this way is easy and possible on any section of the set. The solution according to the invention allows for quick extraction of individual sections from the soft floor after blocking the chain 3 in two adjacent sections, and also improves the working conditions on the wall.
