Abstract

The invention relates to the coal industry and. M. used for feeding, tunneling machines when conducting inclined underground preparatory workings. The purpose of the invention is to increase the reliability of the operation of the spacer-feeder and the spread of the field of application by increasing the range of expansion. The spacer-feeding device is made in the form of two spacer links 1, 2 and a hydraulic screw (HD) 3 of the feed, hinged through intermediate elements (PE) 4 on the spacer link 2 and the body of the combine. Spacer links 1, 2 include pipes 6 with a spacer element 7 and draw bars 8. One end of the last hinge is fixed in one of the radial holes 9 of pipe 6, and the other end is connected with PE 4. In slot 10 made in PE 4, the pipes 6 with a spacer 7 are movably secured. When extending the dead end DG 3 ti 8 of the rear link, they unclench the spacer elements 7, which cut into the beads and the working soil. The link 1 moves forward, feeding the combine. With the reduction of the DG 3, the link 2 is pulled up and the linking of the link 1 takes place. Thus, the remote-feeding device ensures the shifting of the combine on inclined formations and its retention. 1 hp f-ly, 3 ill. (L

The invention relates to the coal industry and can be used to feed roadheaders when drilling the underground preparatory expressions with a slope angle of more than six grams.

; The purpose of the invention is to increase the reliability of work and expand the field of application of the spacer-dispenser, its devices for a roadheader by increasing the range, it expands.

FIG. 1 shows a spacer-dispenser for a tunneling machine, Cha, top view; in fig. 2 - section AA one; in fig. 3 is a view along arrow B in FIG. one.

: A thrusting device, its device for a roadheader contains a front-Ie 1 and rear 2 spacer links and a hydraulic jack 3 feeds hinged through intermediate elements 4 with one end on the rear spacer link 2 and the other On the case of the tunnel combine 5, hinged associated with the front link 1, which ensures the mobility of the heading machine during operation. Spacer links 1 and 2 include pipes 6 with spacer 7 and spacers 8, one end of which is hinged in one of the radial holes 9 of pipe 6, and the other hingedly connected to intermediate element 4. Intermediate element 4 is made with slot 10, in which pipes 6 with a spacer element 7 are movably secured. The spacer element 7 is made in the form of two pointed rods I, one of which is provided with a limiter 12 of the incision. In the spacer element 7 there is a radial hole 13, the diameter of which is equal to the diameters of the radial holes 9 of the pipe 6. The spacer element 7 is attached to the pipe 6 by means of, and, for example, the bolt 14

The gate device for the heading machine works in the following manner.

Before starting the spacer links 1 and 2 regulate the width of production, shuffle, and spacer elements 7 in the pipes

As a result, the tail link 8 8 creates a condition for thrusting, unclamping the spacer elements 7, which cut into the beads and the soil of the mine. The link 1 when extending the stock of the hydraulic cylinder is mixed forward and feeds the driving machine forward. Then, the hydraulic jack 3 is shortened, and the link 2 is pivoted. At the same time, link 1, which works similarly to link 2, spreads, folding the spacer elements 7 when moving forward and bursting them when the hydraulic cylinder 3 shaft is pulled in.

The proposed spacer-dispenser allows not only moving the heading machine on inclined formations, but also ensures its reliable retention in case of an unexpected shutdown of the hydraulic system, which significantly increases the safety of mining operations.
