Description
Предметом изобретени вл етс ручной гидравлический домкрат дл установки в горных выработках раздвижных металлических стоек.The subject of the invention is a manual hydraulic jack for installation in mine workings of sliding metal struts.
Конструкци домкрата предусматривает объединение ведущего и ведомого поршней, а также резервуара дл рабочей жидкости в единую группу так, что ведомый поршень со своим цилиндром размещен внутри резервуара.The design of the jack provides for combining the driving and driven pistons, as well as the reservoir for the working fluid into a single group so that the driven piston with its cylinder is located inside the reservoir.
Головка штока ведомого поршн имеет скобу, при помощи которой захватываетс выдвиЖНа часть стойки.The head of the driven piston rod has a bracket with which it is gripped by the sliding part of the rack.
В рабочем положении домкрат подвещиваетс на замок стойки, который и вл етс его опорой.In the working position, the jack is placed on the rack lock, which is its support.
Применение домкрата облегчает и ускор ет процесс установки стоек и дает возможность сократить численность бригады крепильщиков .The use of a jack facilitates and accelerates the installation of racks and makes it possible to reduce the number of brigade fasters.
На фиг. 1 изображен общий вид домкрата сбоку в разрезе; на фиг. 2 - то же, в плане; на фиг. 3 - то , в разрезе по оси ведущего цилиндра.FIG. 1 shows a general view of the jack in the side section; in fig. 2 - the same in terms of; in fig. 3 is in section along the axis of the master cylinder.
Домкрат состоит из распределительной головки /, в которую ввинчено три трубы: наружна , служаща резервуаром 2 дл масла; внутренн , служаща рабочим цилиндром 3, и труба, вл юща с рабочим цилиндром 4 дл малого порщн 5.The jack consists of a distributor head / into which three pipes are screwed: an outer one serving as a reservoir 2 for oil; the inner one, which serves as the working cylinder 3, and the pipe, which is the working cylinder 4 for a small thickness 5.
В цилиндре 3 движетс рабочий поршень 6, на нижнем конце которого насажен манжет 7 дл уплотнени , а на верхнем конце навинчена головка 8 с отверстием дл валика 9, соедин ющего поршень со скобой 10, захватывающей выдвижную часть стойки. При качании руко тки 11 поршень 6 со скобой выдвигаетс , увлека за собой и прижима к кровле выдвижную часть стойки.In the cylinder 3, a working piston 6 moves, at the lower end of which a cuff 7 is mounted for sealing, and at the upper end a head 8 is screwed with an opening for a roller 9 connecting the piston with the bracket 10, which engages the sliding part of the rack. When the handle 11 is rotated, the piston 6 with the caliper extends, dragging along with itself and the clamp to the roof the sliding part of the rack.
Дл направлени поршн 6 и закрыти резервуара с жидкостью служит гайка 12 с уплотнительным кольцом 13. Домкрат снабжен лапками 14, которыми он упираетс в замок стойки.A nut 12 with a sealing ring 13 serves to guide the piston 6 and close the fluid reservoir. The jack is provided with tabs 14, with which it rests against the strut lock.
