Description

FIG. 2

The invention relates to devices that protect the working space of the bottom from the penetration of roofing rocks into it, and can be used in mechanized coal and mining fortifications to bridge the gaps between the supporting elements.

The purpose of the invention is to improve the protection of the working space between the supporting elements in the mechanized supports.

Figure 1 shows the proposed device for a support section of a support-supporting type, a general view; FIG. 2 shows section A-A in FIG. 3; FIG. 3 shows section BB in a figs. one; in Fig about 4 - section bb In fig about 1 about

The device for blocking intersectional gaps (figs, 1-4) includes a two-console canopy 1 (supporting element) installed between the lugs of the overlap 2 and connected with it axis 3 and hydraulic jack 4 (it is also possible to perform it without hydraulic jack).

The visor 1 (Figures 1-4) consists of a horizontal plate 5 with a vertical eye 6 (figs 1 and 3), glasses 7 (figs4), installed between the vertical hole 6 and the ceiling beams 2, which fix the plate 5 in the transverse direction, two mirrors of a mobile board

8 and 9 of the L-shaped section, located under the plate 5, the movement of which is carried out by means of elastic elements, in this case compression springs 10 (FIGS. 2 and 4), mounted between eye 6 and the inner walls of the retractable flanks on axles 3 and 11, one of which (3) connects the visor 1 with the overlap 2.

Moving retractable sides 8 and

9 in the transverse direction (to the sides of the retractable flanks of adjacent canopies) is limited by their abutment into the inner surfaces of the beams and in the stoppers installed on the 11 o axis. The outer walls of the 12 retractable flanks in contact with the corresponding outer walls of the retractable flanges of the adjacent canopies butts 13

and protrude above the horizontal elements 14 to a height equal to the thickness of the plate 5 o Zoznikayupshch while the frictional forces have a negligible value, as a result of which, when moving the lining section and advancing the sides, the deformation and their malfunction do not occur

To unload the upper surface of the horizontal elements 14 of the sliding sides 8 and 9 from the roof rocks that have spilled on it, the side ends of the slab have bevels 15, by means of which, when you move the side walls into the slab, the squeezing and unloading of the horizontal rocks poured on the surface of the horizontal elements 14

The position of the visor 1 in the vertical plane is controlled by means of a hydraulic jack 4 connected at one end with the vertical eye 6 of the plate 5 and the other with an overlap of 2 o

In the absence of the support-supporting type of the hydraulic jack 4 in the support structures, the visor 1 is controlled by blocking 2 o

Figures 2-4 with dash-dotted lines indicate the positions of the sliding walls 8 and 9 with the springs compressed 10

The device works as follows.

The pre-assembled visor with the sides locked in the extreme retracted position is mounted on the overlap 2 and connected with the lower axis 3, and if necessary with a hydraulic ram 4 o

Upon completion of the mounting of the lining sections in lava, the sliding sides 8 and 9 are parted and under the action of the springs 10 move to the sliding sides of adjacent canopies until they come into contact with the side surfaces of the outer walls 12, with the maximum travel of the sides moving overlapping the beams 2 and the stoppers to axis 11 o The contact between the vertical walls of the retractable sides of the adjacent canopies is maintained continuously and automatically by the forces of the springs 0, while since the retractable sides 8 and 9 contact only the roof with a roof Slab of the outer walls 12, Toe, with a small surface, the plate perceives the main part of the mountain load of the roof. 5 The contact between the retractable sides of the adjacent canopies is maintained both when the gap between the goats and the stepwise (different in height) positions of the canopies along the roof reducing the size of the gap between the visors, the retractable boards move inwards under the slab 5, while the loose fines (between the protrusion of the vertical wall and the side end of the slab) are squeezed up through the bevels 15 into the roof and are called d, care blockage when shifting sections of

Claims (1)

The invention The device for blocking intersectional gaps, including retractable flanges that are spring-loaded from the first ends with outer walls at the second ends, are installed in a supporting element having a horizontal plate with an eye connected to the axis with lugs, In order to improve the working space fencing, each side is L-shaped, their first ends are arranged parallel to the protruding support element between this propsha and the lugs and are made with holes in which the joint axis of the supporting element with overlapping is placed, while the outer the walls of the sliding sides protrude above their horizontal elements to a height equal to the thickness of the horizontal plate, and the lateral ends of the plate have bevels about   C 7 j / / / 73/5 8 / 7/7 7 Fi. 1377403 BB Srig. 3 bb / V S 13 12
