Description

(54) МЕХАНИЗИРОВАННАЯ ПРОХОДЧЕСКАЯ КРЕПЬ(54) MECHANIZED PASSAGING STRAP

1one

Изобретение относитс к горному делу и может быть использовано при проходке горизонтальных горных выработок.The invention relates to mining and can be used when drilling horizontal mine workings.

Известна оградительна проходческа крепь ПМК-1, включающа гидростойки, св занные в верхней и нижней част х гидродомкратами , верхн ки с роликами, перекрыти и направл ющие, шарнирно св занные с гидростойками 1.The PMK-1 protective pit support is known, which includes hydraulic legs connected in the upper and lower parts by hydraulic jacks, roller tops, overlaps and guides, which are hinged to the hydraulic supports 1.

Недостатком известного изобретени вл етс то, что щарнирна св зь направл ющих и гидростоек не обеспечивает надежность их взаимодействи , особенно при боковом горном давлении.A disadvantage of the known invention is that the hinged connection of the guide rails and hydraulic legs does not ensure the reliability of their interaction, especially at lateral rock pressure.

Наиболее близким техническим решением вл етс механизированна проходческа крепь, состо ща из секций, кажда из которых включает гидростойки, гидродомкраты перемещени , верхн ки с роликами , перекрыти и направл ющие, соединенные с гидростойками посредством управл емых гидроцилиндрами ползунов с кольцами 2.The closest technical solution is the mechanized lining, consisting of sections, each of which includes hydraulic legs, movement hydraulic jacks, tops with rollers, overlapping and guiding, connected to the hydraulic legs by means of hydraulic slide cylinders with rings 2.

Недостатком такого технического рещени вл етс то, что передвижение стоек и перекрытий производитс индивидуальными гидродомкратами, т. е. кажда параThe disadvantage of such a technical solution is that the movement of the pillars and floors is made by individual hydraulic jacks, i.e. each pair

гидростоек и перекрытий соединена гидродомкратом , что приводит к неравномерному шагу передвижени крепи за каждый цикл работы. Дл того, чтобы выдержать заданный щаг, необходимо дополнительноHydro-supports and floors are connected by a hydraulic jack, which leads to an uneven pitch of the support of supports during each work cycle. In order to sustain a given schag, you must additionally

5 производить передвижение крепи, что также снижает эффективность работы крепи.5 to produce the movement of lining, which also reduces the efficiency of the lining.

Цель изобретени - повышение надежности работы крепи.The purpose of the invention is to increase the reliability of the support.

Это достигаетс тем, что ползуны вы ,Q полнены на всю длину секции и установлены в направл ющих друг над .другом с возможностью перемещени по направл ющим относительно друг друга, при этом гидростойки соединены с нижними и верхними ползунами поочередно.This is achieved by the fact that the sliders you, Q are full for the entire length of the section and are installed in guides over each other with the possibility of movement along the guides relative to each other, while the hydraulic legs are connected to the lower and upper sliders in turn.

Claims

A 2Q type consists of sections, each of which includes hydraulic legs 1, which are inserted into rotating rings 2, which are hingedly connected to the upper slide 3, and hydraulic wheels 4 inserted into rotating rings 5 connected to the lower slide 6, moving along the guide 7 by means of a hydraulic jack 8, as well as from upper 9, connected by hydraulic jacks 10 with overlapping section 11. The guides 7 are attached to the sides of the combine. To facilitate the movement of the top 9 relative to the overlap between them, the rollers are installed in the form of a frame 12. The movement of the lining is carried out in two stages. At first, one of the sections is moved, for which the hydraulic legs 1 of the moved section are unloaded. In this case, the action of the rock pressure is perceived by the unraveled hydrostables 4. The unloaded hydroresistant 1s are moved by means of a hydrojet. and hydraulic jacks 10 interacting with the tops 9 of the movable and fixed sections are installed in a vertical position. The other section is moved in the same way and the hydraulic legs 4 with the slider 6 are moved using the hydraulic cylinder 8. The mechanized tunnel support of this design is more effective due to the fact that the support sections are moved with one hydraulic cylinder 8 on each side of the support and the hydraulic supports with grooves a certain place in the slider allows you to precisely withstand the specified movement of the support sections. Claims of the invention: Mechanized head supports consisting of sections, each of which includes hydraulic legs, movement hydraulic jacks, roller tops, overlaps and guides connected to hydraulic legs through slide-operated hydraulic cylinders with rings, so as to increase the efficiency of the lining, slides performed over the entire length of the section and installed in guides one above the other with the ability to move along the guides relative to each other, while the hydroracks are connected to lower and upper crawlers alternately.
