Abstract

The invention relates to the fixing of clearing faces with mechanized supports, sections of which are moved by hydraulic jacks (HD) located on the sides of the base. The goal is to increase the reliability of work by ensuring the direction of movement and excluding the introduction of the front of the base of the support in the soil. The mechanized lining contains sections with overlaps associated with the downhole and dead-up hydraulics 8. The cups of hydraulic girders 8 are fixed on the bases hingedly bound

with the ends of the conveyor 14 through guide beams (NB) 2 arranged between the bases and parallel to them. On the latter there are hydraulic shifters (DG) 3. Each NB 2 is connected with the rods 11 DG 3 and by means of the bracket 6 with the downhole part of the base. The bracket 6 has an elongated hole and a quick release coupling consisting of an eye and a wedge. The rod 11 DG 3 is articulated to the NB 2 in its middle part by a roller 12, and the cylinder through a flexible link 13 to the conveyor 14. As the combine passes, the lining sections move to the conveyor 14. Each section moves to two DG 3. 3 silt .

The invention relates to mining, in particular, to the fixing of the mining faces of the mechanized clamps, sections of which are moved by hydraulic jacks located on the sides of the base.

The aim of the invention is to increase the reliability of operation by ensuring the direction of movement and excluding the introduction of the front part of the base of the lining into the soil.

FIG. 1 shows lining, plan; in fig. 2 — node I in FIG. one; in fig. 3 shows section A-A in FIG. one.

Mechanized lining consists of sections of the same type 1 and guide rails 2 with hydraulic jacks 3 of movement. The guide beams 2 are attached to the sides of the base of the support in the zavalny part by means of brackets 4 and rollers 5, and in the downhole part - through a special bracket 6 with an oblong-shaped hole 7, installed under the glass of the front hydraulic column 8, and quickly detachable connection consisting of lugs 9 and wedge 10. Each hydraulic ram is equipped with a hydraulic jack of movement with a fit on the outer diameter of the cylinder. The hydraulic cylinder rod 1 is pivotally connected to the guide beam in its middle part by a roller 12, and the cylinder through a flexible link 13 is connected to the conveyor 14.

In the initial position of the section, the crepe is spaced from the conveyor to the shifting step, the rods of the hydraulic jacks of movement are extended. As the combine passes, the lining section moves toward

pipeline. Each section is moved by two jacks. Due to the fact that the guide beams with hydraulic jacks are fixed on the base in the downhole and downhole parts, the digging of the base of the base into the ground and the turn are prevented when the support section is moved.

Claims (1)

Claims of the invention: Mechanized lining, comprising sections that have overlap associated with the downhole and downhole hydraulic legs; the cups of which are fixed on the bases, hingedly connected by the filling ends with the conveyor through the directional beams located between the bases parallel to the latter with the hydraulic shifters installed in them, the rods of which are hingedly attached to the direction of the beams, characterized in that in order to increase the reliability of work by ensuring the direction of movement and to prevent the front part of the base from penetrating into the soil, each pilot beam is additionally connected to the bottom hole of the base By means of a bracket fixed under a glass of a bottomhole hydraulic rack and made with an elongated hole, the downhole end of each guide beam is connected to the bracket by means of a wedge installed in its hole and its wedge fixed on the base by means of a fork and roller, and the shifter cylinder is attached to the conveyor by means of a flexible link. fpue.2.
