Description
(54) МЕХАНИЗИРОВАННАЯ КРЕПЬ СОПРЯЖЕНИЯ(54) MECHANIZED STRESS STRIPPING
1one
Изобретение относитс к горному длу и может быть использовано при разработке угольных пластов подземным способом при креплении сопр жени лавы со штреком.The invention relates to mining and can be used in the development of coal seams by the underground method when fixing the interface of lava with a drift.
Известна механизированна крепь сопр жени лавы со штреком, включающа основание, гидростойки, на которые опираетс перекрытие, промежуточное основание и силовые домкраты| 1 J .The known mechanized lining of the interface between the lava and the drift includes the base, the hydraulic supports on which the floor, the intermediate base and the power jacks are supported | 1 j.
Недостатком этой крепи вл етс ненадежное крепление- сопр жени лавы и выработки при расположении их на разных уровн х.The disadvantage of this lining is unreliable fastening - mating of lava and excavation at their location at different levels.
Известна также механизированна крепь сопр жени , включающа основание с тумбами, перекрытие, опирающеес на гидростойки, промежуточьюе основание, шарнирно-соединенное с тубами , и силовые домкраты1 23 .Also known is the mechanized lining of the mating, which includes the base with the thumbs, the overlap resting on the hydrocalls, between the base, hingedly connected to the tubes, and the power jacks1 23.
Така крепь сопр жени не предотвращает от обрушени боковые стенки выработки сопр жени лавы со штреком и не обеспечивает надежного креплени сопр жени , а также пропуск воздуха через крепь в вертикальном направлении ..This kind of mating does not prevent the side walls of the lava mating with a drift from collapsing and does not ensure a reliable attachment of the mating, as well as the passage of air through the lining in the vertical direction ..
Целью изобретени вл етс повышение надежности креплени выработки сопр жени ,The aim of the invention is to improve the reliability of the fastening of the mating,
Это достигаетс тем, что механизированна крепь сопр жени снабжена боковыми элементами, шарнирно-соединенными посредством силовых домкратов с,тумбами, при этом нижние части боковых элементов телескопичесжи св заны с основанием, а на верхние установлены гидростойки.This is achieved by the fact that the mechanized lining of the mating is equipped with side elements hinged and connected by means of power jacks to the pedestals, while the lower parts of the lateral elements are telescopically connected to the base, and hydrorests are mounted on the upper parts.
На фиг. 1 изображена крепь сопр жени спереди с частичным вырывом (по тумбе и промежуточному основанию на фиг. 2 - разрез А-А на фиг. 1.FIG. Figure 1 shows the mating support at the front with a partial tear-out (along the bollard and the intermediate base in Fig. 2 — section A-A in Fig. 1.
Механизированна крепь сопр жени имеет основание 1 с установленными на нем тумбами 2 , соедине 1ные с основанием посредством телескопов 3 боковые элементы 4, которые посредство .м силовых домкратов 5 шарнирно соединены с тумбами, установленные наклонно и опирающиес на боковые элементы гидростойки 6, взаимодействующие с перекрытием 7 крепи, ограждение В, шарнирно-св занное с перекрытием и управл емое домкратом 9. Ограждение снабжено выдвижной частью 10, котора заканчиваетс опорными лыжами 11. Перекрытие крепи опираетс на гидростойки 12, которые установлены-на тумбах. С пеThe mechanized lining of the mating has a base 1 with thumbs 2 mounted on it, connected to the base through telescopes 3 side elements 4, which are pivotally connected to the thumbs by means of power jacks 5 mounted obliquely and resting on the side elements of the hydrorack 6 interacting with the floor 7, an overhang B, articulated with overlap and controlled by a jack 9. The fence is provided with a sliding part 10, which ends with supporting skis 11. The overlapping of the supports rests on hydroracks 12, which are mounted on thumbs. With ne
