Изобретение относитс к горному делу и может быть использовано при проведении подготовительных выработок проходческими комбайнами.FIELD OF THE INVENTION The invention relates to mining and can be used during development workings by roadheaders.
Известны передвижные механизированные безразгрузочные крепи, включающие раму с гидростойками и роликами, верхн ки и рулонную сетку.Known mobile mechanized unloading lining, including a frame with hydraulic and rollers, top ki and roll grid.
Однако эти крепи требуют создани больших усилий при передвижке в безразгрузочном режиме работы.However, these lining require the creation of large efforts when shifting in a no-load mode of operation.
Предлагаема крепь отличаетс от известных тем, что верхн ки выполнены с продольными желобами, в которых размещены ролики . Это уменьшает усили при передвижке крепи, в безразгрузочном режиме работы.The proposed lining differs from the known ones in that the tops are made with longitudinal grooves in which the rollers are placed. This reduces the effort when shifting the lining, in the non-loading mode of operation.
На чертеже изображена предлагаема крепь.The drawing shows the proposed lining.
Крепь состоит из верхн ков 1, рамы 2, гидростоек 3, устанавливаемых на раме гусеничного хода, гидродомкрата 4 передвижени верхн ков, роликов 5, сетки 6, помещенной в рулоне 7 на лотке 8, и продольных желобов 9.The support consists of upper 1, frame 2, hydraulic rails 3 mounted on the crawler frame, hydraulic jack 4 of the upper wheels, rollers 5, mesh 6 placed in roll 7 on tray 8, and longitudinal grooves 9.
Крепь работает следующим образом.The support works as follows.
Гидродомкрат передвижени , выдвига щток, перемещает шарнирно соединенные с ним верхн ки и разматывает рулон с сеткой, свободный конец которой вводитс в пространство между верхн ками и кровлей выработки . После перемещени верхн ков на установленный шаг передвижки подача рабочей жидкости в гидродомкрат прекращаетс . Непрерывно подаваемый на забой гусеничный ход перемещает раму крепи относительно верхн ков и надвигает цилиндр гидродомкрата на щток до тех пор, пока не будет исчерпана вс длина щтока. Перемещение верхн ков и рамы крепи относительно друг друга происходит по роликам, размещенным в продольных желобах, без сн ти распорного усили в гидростойках.The hydraulic slide of the movement, pushing out the shafts, moves the tops which are hinged to it and unwinds the roll with the net, the free end of which is inserted into the space between the tops and the roof of the excavation. After the tops have been moved by the set step of movement, the supply of working fluid to the hydraulic jack is stopped. Continuously delivered to the bottom, the crawler moves the support frame relative to the tops and pulls the cylinder of the hydraulic cylinder to the brush until the entire length of the brush is exhausted. The movement of the tops and lining frames relative to each other takes place along the rollers placed in the longitudinal grooves, without relieving the strut force in the hydraulic posts.
