Изобретение относитс к области горного дела, в частности к крепи подземных горных вьфаботок.The invention relates to the field of mining, in particular to the lining of underground mining works.
Известна крепь горных выработок, включающа верхн к и стойки, соединенные между собой скобами с планками и гайками ij. Недостатком такой крепи вл етс значительна трудоемкость ее установки и демонтажа, а также низкий процент повторного использовани крепежных деталей.Known lining of mine workings, including the upper and the rack, interconnected brackets with slats and nuts ij. The disadvantage of this support is the considerable complexity of its installation and dismantling, as well as the low percentage of reuse fasteners.
Известна также друга крепь горных вьфаботок, включающа верхних, стойтсн и узлы соединени , выполненные в виде скобы с осью, на которой установлен Поворотный эксцентриковый кулачок 2j.Also known is another lining of the mountain mountings, including upper, stanchions and joints, made in the form of a bracket with an axis on which the Rotary eccentric cam 2j is mounted.
Целью изобретени вл етс ускорение процесса установки крепи.The aim of the invention is to accelerate the installation of the support.
Это достигаетс тем, что скоба узла соединени выполнена замкнутой,, а поворотный эксцентриковый ку.чачок снабжен полувтухгкой, котора установлена на его внутренней поверхности иThis is achieved by the fact that the clip of the junction is made closed, and the rotary eccentric piece is provided with a half-bale, which is mounted on its inner surface and
оперта на скобу, служащую осью вращени кулачка.it is supported on the bracket serving as the axis of rotation of the cam.
На фиг. 1 изображена крепь, ойций вид; на фиг. 2 - сечение А-А на фиг. 1; на фиг. 3- сечение Б-Б на фиг, 2.FIG. 1 shows the lining, otic view; in fig. 2 is a section A-A in FIG. one; in fig. 3- section bb in fig. 2.
Крепь состоит из верхн ка 1, стоекThe support consists of top 1, racks
2 и узлов соединени 3, каждый из которых включает поворотный эксцентриковый кулачок 4 и замкнутую скобу 5. Эксцентриковый кулачок 4 снаб-2 and connection nodes 3, each of which includes a rotary eccentric cam 4 and a closed bracket 5. The eccentric cam 4 is provided with
жен полувтулкой 6, котора установлена на его внутренней поверхности и оперта на закткнутую скобу 5, служащую осью вращени кулачка 4.It is worn with a half-sleeve 6, which is mounted on its inner surface and supported on a clamped clamp 5, which serves as the axis of rotation of the cam 4.
Крепь устанавливают следующик образом .The support is installed in the following manner.
На стойку 2 надевают замкнутую скобу 5, затем верхн к 1 укладывают внахлестку на стойку и на место нахлестки продвигают замкнутую скобу 5. После этого кулачок 4 устанавливают полувтулкой 6 на замкнутой скобе 5 как на оси вращени и поворачивают его до упора в верхн к, при этом дл пред-A closed bracket 5 is put on the rack 2, then overlapped on the rack to the top 1 and the closed bracket 5 is moved to the overlap. this for
