Abstract

The invention relates to equipment for fastening, in particular to cross-shaped anchorages, intended for mining mineral deposits without first carrying out internal drifts. The goal is to improve the efficiency of lining, to ensure overall dimensions for the passage of people to the transportation of goods through the development, to improve the ventilation of generation and installation work in it, and to reduce the safety of working conditions. To do this, in the base 1 of the lining section along its longitudinal axis there is a power expansion element 5. At one end it is fixed in the base 1, and the other end is attached to the base 1 by means of the attachment assembly 6 and rigidly connected to the base plate placed at the base 1 moving in direction 8. In the traverse 7 one.m. the end is rigidly fixed, flexible elements (ET) 9. Their other end is fixed in the mount. GE 9 is moved through blocks 11 mounted on axis 12. Their number is determined depending on the carrying capacity of the section. Moving in the guides 8 along the longitudinal axis of the base 1, the yoke 7 transmits the thrust force of GE 9, which, moving through the blocks 11, transfer the thrust force to the overlap 2. The latter turns around the axis 3 and the visor abuts the roof according to the roof profile. After reaching the specified thrust force, a miner stand is brought under the end of the visor. 3 il. w (lu sooel about

T-HIC: O; NOSMTS I TO WRITTEN KFJC ;; i .PHCHMSMYY D.: 1 mining or-, (j mexico without excavation of excavation tracks, 1) to save excavation tracks 1 (to dig out the fossil tracks), the inventor applied the invention. ((- maintenance of work support, ensuring overall dimensions for the passage of people and the transportation of goods in working out, improved handling and installation work, in it the safety of working conditions in the workout.

FIG. 1 shows a low-rise support section; in fig. 2 - view A on (} jnr. 1; in Fig. 3 - section BB on phi1 1.

Section lining includes the base 1, pivotally connected to the overlap 2 through the axis 3, the visor 4, pivotally connected to the overlap 2, the power expansion element 5, razlozhenny base 1 along its longitudinal axis, which is rigidly fixed to the end, and others m the end of the nrikre 1len to the base through the attachment point b and is rigidly connected to the crossmember 7, moving in the guide elements 8. The flexible elements 9, the number of which is determined depending on the carrying capacity of the section, are firmly fixed with a single fin. a yoke 7, and others - rigidly fixing at the node 10. The flexible elements 9 are moved through the blocks 11 mounted on the axle 12. The spreader bar 13 is mounted by a visor 4.

The section works as follows.

The base 1 of the section is installed on the working ground. From the power spacing element 5, at one end rigidly fixed in the base 1, and to the other connected to the base by means of the attachment unit 6, the thrust force is transmitted to the crosspiece 7, to which the flexible elements 9 are attached, the second end they are fixed in the fixing unit 2 of the overlap 2.

the guides 8 along the longitudinal axis of the base 1, the yoke 7 transfers the thrust force to the flexible elements 9, which, through the blocks 11 mounted on the axis 12, transmit the thrust force to the overlap 2. At the same time, the overlap 2, turning around the axis 3, begins to move its working part to the roof of production. The visor 4, lifted along with the overlap 2, as it approaches the roof of the excavation, abuts the rear end of the roof with a rear end, begins to unfold and takes up a position in accordance with the roof profile. Upon reaching the specified thrust force, the section takes up a working position, and the EI end of the visor 4 is supplied with a manhole strut 13 (e.g., wood, wedge friction strut, etc.) intended to prevent tilting | log (sides. To turn the visor 4 when approaching the roof of the

0 can be used additional si-; 1. a spacer fixed in the supporting part of the overlap 2 (not shown) and connected with the second end to the visor 4.

Claims (1)

Claim section A side-support section, comprising an overlap, hingedly connected with the base and a visor, hingedly attached to the overlap of a power expansion element, a manhole rack, characterized in that, in order to increase work efficiency, improve the conditions for airing the mine work and installation work. it is equipped with a traverse, guiding flexible elements, passed through 5 blocks, while the power expansion element is located at the base along its longitudinal axis, with one end rigidly attached to the base, and the other through a fixing unit to the traverse, which is mounted in rails fixed to the base, flexible elements at one end fixed to the traverse, the other - to overlap, and their blocks are fixed in the lower part of the section. g // /// /// Editor G.
