Description

The subject of the invention is a sectional mechanical fastening, which is movable along the entire length of the lava, consisting of supports and ceilings, and the sections are moved according to the principle of shagany by alternating tension of two ropes.

The supports (pillars) of the fastener are sliding; at the roof and on the soil of the stratum, they are connected with the overlaps on the hinges. On the lower overlap of each section (two blocks are installed to guide the ropes.

Such attachment faces of moving faces with moving sections are known.

A distinctive feature: the described mechanical movable fastening consists in the fact that its construction allows carrying out the shifting movement simultaneously along the entire length of the lava using successive shifting of its sections, by alternately pulling two ropes through appropriately arranged bunks of blocks on each section (on one section x through one at small distances x and at other sections x at large distances x).

Racks with overlaps are pivotally connected by means of stops and springs at the upper overlaps, thereby automatically latching the lagging sections between the roof and the soil and relieving the movable sections from pressure by tensioning the rope.

FIG. 1 shows a vertical section of the support structure; in fig. 2, 3 and 4 movements of the support sections, plan view.

The K1repi design (Fig. 1) consists of supports 1, overlaps 2, hinges 3 connecting the supports and the overlap, stops 4, springs 5, blocks 6 (two on each section for a close distance 12). blocks 7 (two for each section at a great distance 131

During the tension of the rope 8 (Fig. 2), sections 9 are wedged, and sections 10 are released and advanced under the effect of tension of the rope 8 and roller 7, while the rope And is weakened.

FIG. 3 shows the completed position of movement of the sections 10; in fig. 4-complete movement of sections 9 and 10 during tension of the rope And and the weakening of the rope 8.

Claims (2)

1. Mechanical mobile fastening, consisting of sections with supports and ceilings at the roof and soil of the seam, characterized by Teivi; tlTojt; two ropes were applied to alternately move the sections across the chest to the chest, enveloping two ropes alternately stretched along each section two blocks. 2. The form of mounting according to claim 1, wherein when moving the attachment, the lagging sections are automatically wedged between the roof and the soil, and the movable sections are released from the pressure during tension of the rope. tsh // Sh11 {.: shmshshshMSh / GT5-- G ::;:; Ci77i..r2Q i IL 1 / I ll4 -, / i-O 1 --I / 1  I l / - l .JLjLJi ZJL / I / j us l9 sh 19 t -r-and -y --- 1i t-j -TP; / // w / im 13
