MECHANIZED ENCLOSURE 00 WALLS WITH HYDRAULIC BASE

The subject of the invention is a powered support intended to work in walls selected with a hydraulic propelling system, especially in walls led after a sand fall.

There are well-known mechanized proppant supports, in which the stabilization system is solved by a lemniscate device.These supports are inherently very heavy, because the size of their mass is determined to a large extent by the lemniscate system itself. inherently resistances are very great and are associated with frequent outflows of sand into the working space Attempts to solve the problem by constructing the tread of the support mounted under the roof of the excavation did not bring any practical effects, because the tread thickness increased immediately, ^ (^ the suspension of the section on adjacent sections and the weight of the casing grew again · The thickening of the canopy was the reason for the lack of the combine's ability to move freely under the roof secured with this casing ·

The aim of the present invention is to eliminate the above drawbacks and inconveniences and to have such a structure that, with a small size, a significant simplification of the structure and a certain stabilization system, allows for effective operation in backfilling walls with a very wide range of heights.

The essence of the invention consists in the fact that the casing has two stabilizing devices The first one is made in the form of a clamp permanently connected to the stand The brace has openings through which spring bars pass freely, fixed with the other end in the base of the casing The second stabilizing device has a hydraulic support poles articulated to the main canopy · These rods, in the case of recessing into the housing in the sand saucer, are stretched against the floor of the excavation

The invention is illustrated in the example of the drawing, in which Fig. 1 shows a casing section in a side view, Fig. 2 shows this section in a front view, and Fig-3 shows the position of two adjacent sections in a top view.

The casing according to the invention has four stands 1 stretched between the divided floor 2 and a basic plate canopy 3. The canopy 3 has 4 front and rear canopies connected by means of square bars 6. A clamp 7 is permanently attached to the stands 1, in which openings are made for bars 8. These bars are mounted with the other end in the floor 2 · About the canopy 3, hydraulic bars 9 are articulated with the possibility of being stretched against the floor of the excavation · Support sections are installed in the wall at some distance from each other, so that between them, communication channels 10 are formed, allowing people to pass from the working field to the filling field. The work of the casing is bursting. During the normal cycle, the casing works like any casing, and its stabilization is achieved by means of springy rods 8, and the hydraulic rods 9 hang freely above the floor runners · The rods 9 expand into the floor of the excavation in two cases: First, when the jacks have been blown up, It is impossible to dislodge the casing with a typical sliding system mounted in the floor 2, while the bars 9 are spread, the stands 1 are robbed, which causes the floor 2 to be torn out of the silted sand bottom. forward, similarly to a person moving on crutches · Breaking the sand out of the sand runners, the short stroke of the casing relieves the section from excessive loads during its movement, which, with the normal expansion of the uprights 1 and release of the load on the poles 9, then enables the normal operation of the casing. The second case when the bars 9 are used to stabilize the casing sections is when as a result of bends, folds, temporary excessive sloping of the deck, these poles are used for stoppers and for positioning the sections.

The advantage of said invention is the extreme simplicity of the housing. Its small weight, the ability to easily overcome the associated resistance to movement when moving the casing, as well as small dimensions of the canopy thickness in the sash part allowing for convenient movement of the roadheader along the wall. a wide range of minimum and maximum heights within one type.
