Description

one

The invention was sent to Konr.eiiepiioMy transport and can be used in the conveyor delivery of coal in the mines.

The scraper co-ceil is known, which is made up of a section consisting of sections that are connected with one another, with troughs of the pan which overlap each other and are fastened with the help of a fixed rope {1. But it does not allow a significant lengthening of the rod and therefore is not applicable in the closed-shaped flank.

The closest technical solution to the invention is a pan-mounted scraper conveyor, including 1 section, associated with jacks, and inserts for closing the gaps between sections 2.

This pan tilting makes it possible to compensate for the increase in its length, which is obtained during the sectional move to slaughter, which is achieved both by the joint of the sections by a sliding ball, the entrance to them in the slots of the sections, and hydraulic jacks, the stem of each of which is associated with one section of the railing, and the cylinder on the other.

The disadvantage of this lattice design is the impossibility of increasing its length, since only alternate sectional compensation of the increase in length obtained when shifting on inclined layers, which is caused by the construction of sections, is in such a position.

It also does not provide for the scrubbing of the scrapers, working with a large expansion or, on the contrary, cutting, in an automatic mode, without full-length jacks that feed the face, and without a heavy transport of material between sections. Therefore, this becoming for working in closed holes on flat seams is not suitable.

The purpose of the invention is to provide an increase in the length of the rod.

This is achieved by the fact that the inserts are made with the possibility of placement in or. sections and pivotally associated with them jacks.

The drawing shows a part of the proposed panning without upper nanravl ynil xolok, vnd in plan.

Mounted rack contains narrow 1 and wide 2 sections with two L-shaped sides

and diin1, I eat. The sections are physically connected one to the other by pairwise entering the narrow pan into wide ones. On all sides of the pan, on the side of the face, there are 3 solid forces for fixed cilidars 4 and

stocks 5 jacks sliding. The latter are suitable for shrinking or stretching of the pan-head, if necessary, changing its length. The tele-connection of the pan is made with a gap, which allows them to be placed at an angle relative to each other and thus bend around the bottom of the block, which is worked out along the contour.

The pan-head works as follows.

During the operation of the conveyor in an annular closed downhole, with the next gate valve under the bottomhole, compression (including, in particular, automatically) is applied to the compression jacks. Under their influence, the pan sections telescopically enter each other in pairs, the ring of the conveyor head is shortened to a value due to the distance to the bottom and partially adjustable allowable forces developed by the jacks. If it is necessary to increase the length of the conveyor ring, the jacks are turned on and the length of the conveyor is increased.

The use of a telescopic tongue stand, which changes its node length by the action of the jacks, will reliably solve the problem of ensuring, if necessary, changing the length of the scraper conveyor during its work in the face.
