Изобретение относитс к горной промышленности .The invention relates to the mining industry.

Известна секци шахтной механизированной . крепи, включающа основание, перекрытие, гидростойкн и дополнительную стойку, закреп- , ленную в верхней части секции с возможностью откидыватьс 1 .Known section shaft mechanized. the support, including the base, the overlap, the hydrostatic and the additional stand fixed in the upper part of the section with the possibility of reclining 1.

Недостатком указанной секции вл етс невозможность обеспечени безопасного ведени работ.,0The disadvantage of this section is the inability to ensure safe maintenance., 0

Наиболее близким техническим решением вл етс секци шахтной механизированной крепи, включающа основание, гидростойку, перекрытие с козырьком, дополнительную стойку , шарнирно соединенную с гидродомкратом ,5 и установленную с возможностью разворота в вертикальной плоскоста 2.The closest technical solution is the section of the mine mechanized support, comprising a base, a hydraulic post, an overlap with a visor, an additional post pivotally connected to the hydraulic jack, 5 and installed with the possibility of turning in a vertical plane 2.

Недостатком этого технического решени вл етс невозможность обеспечени безопасное-2Q ти ведени работ и устойчивости секции крепи при широкозахватной выемке угл .The disadvantage of this technical solution is the impossibility of ensuring the safe-2Q of these operations and the stability of the support section during wide-angle coal excavation.

Цель изобретени обеспечение устойчивости секции крепи и безопасности ведени работ.The purpose of the invention is to ensure the stability of the lining section and the safety of operations.

Это достигаетс тем, что козырек выполнен с цилиндрической опорой, а дополнительна стойка снабжена вилкой с цилиндрической проточкой дл взаимодействи с цилнцдричсской опорой, при зтом вилка шарнирно прикреплена к торцам цилиндрической опоры.This is achieved by the fact that the visor is made with a cylindrical support, and the additional rack is equipped with a cylindrical groove plug for engagement with a cylindrical support, while the fork is hinged to the ends of the cylindrical support.

На фиг. 1 изображена секщ1 крепи, вид сбоку; на фиг. 2 - выдвижной козырек со стойкой и приводом установки дополнительной стойки.FIG. 1 shows sec1 lining, side view; in fig. 2 - retractable visor with a rack and drive installation of an additional rack.

Секци шахтной механизирова шой крепи содержит гидростойки 1, заднее ограждение 2, основание 3, внутри которбго встроен гидродомкрат 4 передвижки секции крепи, раздвижное перекрытие 5 со встроенным гидроцилиндром 6 дл выдвижки козьфька 7 с дополнительней стойкой 8 и приводом 9 ее установки. На козьфьке 7 закреплена цилиндрическа опора 10, а дополнительна стойка 8 снабжена вилкой И с цилиндрической проточкой дл взаимодействи с далиндрической опорой.The mine mechanized roof support section contains hydroracks 1, rear guard 2, base 3, inside is built hydraulic jack 4 advancing of the support section, sliding cover 5 with built-in hydraulic cylinder 6 for advancing goat 7 with additional rack 8 and drive 9 for its installation. A cylindrical support 10 is fastened to the kozfke 7, and the additional support 8 is equipped with a fork I with a cylindrical groove for interacting with a distal support.

Claims

The drive 9 for installing the additional post 8 is one or two hydraulic cylinders pivotally attached to the extendable visor 7 and to the fork 11 of the rod of the additional rack 8. Due to the cylindrical shape of the support 10 at the goat 7, the surface of the fork 11 at the rod of the additional rack 8, the latter can be installed with a different angle of inclination to the slaughter plane, i.e. choose the angle that ensures the stability of the support. Section mechanized lining works as follows. The lining section is supplied to the face immediately after the movement of the executive body of the excavation machine. Therefore, at first, the additional post 8 is folded into the transport position (shown in Fig. 2 by a dotted line) and the visor 7 is extended using a hydraulic cylinder) 6 over the combine, while the support section is moved. After the passage of the body of the excavation machine, the rack 8 is installed and spread. Thus, the section of the mine mechanized support of such a construction ensures the safety of operations due to the reliable and timely fixation of the clearing generation, and it is stable in the case of wide-angle coal mining. Claim section Mechanized shaft support, including base, hydraulic, overlapping with a visor, additional stand, pivotally connected with a hydraulic jack and installed with the possibility of turning in a vertical plane, characterized in that, in order to ensure the stability of the support section and the safety of work, the visor is made with a cylindrical support, and the additional stand is provided with a fork with a cylindrical groove to interact with the cylindrical support, while the fork is hingedly attached to the ends of the cylindrical support.
