SU400710A1 - DEVICE FOR INSTALLING A FLEXIBLE OVERLAPPING - Google Patents

Description

one

From: Breton is related to the coal industry and can be used for the layered excavation of powerful coal seams with mechanized interlayer overlaying from a metal grid or others} that are able to replace its materials.

The device is designed to work with (Crepe mn, having a protective part.

A well-known device for mechanized construction of an interlayer overlap of metal mesh, working with a mechanized complex KM-81.

However, in the known device, the unreliable opening is unreliable due to penetration of spillage into the gaps between the fences under the grid and further into the working space when working on the underlying layer.

The purpose of the invention is to increase the reliability of the device in operation.

This is achieved by the fact that the reels of the device for laying a flexible overlap are provided with frames that are articulated by means of spring-loaded telescopes.

FIG. 1 shows the proposed device with a partial cut (telescopic connection), side view; in fig. 2 - the same with a partial section: a cut-out (along the hinge. To the connection of frames with the protective part of the support), a plan view.

The device for laying overlap consists of telescopic frames 1 and 2, pivotally connected by axes 3 with a binder, and an integral part of the latch 4. In the frame lashes, at different levels but vertical, there are drums 5 and b with ribbons 7 and 8 of flexible overlap. The tapes of flexible overlap are ironed under the rolls of 9 fencing rolls. To adjust the distance from the limiting part of the support to the drums, the frames are equipped with telescopically connected pipes 10 and 11. The maximum distance from the barriers of the slide to the drums is determined by the length of the flexible adjustable sleeves 12. The telescopes are spring loaded by springs. 13. The drums are fixed at different levels by means of a flexible, adjustable strap 14. The retaining strips 15 prevent the drums from falling out of the frames.

The device works as follows.

The drums 5 and 6 with the ribbons 7 and 8. The flex. Of which are overlapped, alternating respectively on the frames 1 and 2 on all of the enclosures, on the edge of the lava; at the same time, the drums 6 on the frames 2 are installed on the night of the lava. With the help of flexible straps 13, the distance from the drums to the restrictive part 1 of the fixture is set depending on (Coherent conditions in the lava and the size of the cream. Drums 5 on rav. Max 1 by means of straightening 14 install 3

They are raised above the reels 6. When the coal is dredged in the lava of the mechanized section, the lining periodically moves a step of the movement. Together with the protective parts, the curls of frame 1 and 2 with the reels 5 and 6 are also relocated. In this case, the belts 7 and 8, impacted under the roles of almi 9 in the side of the dam, and depressed are collapsed: by mi breeds, unrolled from the drums and laid on the soil of the lava. The overlap of the joint (the width of the tape is achieved due to the fact that the total width of two adjacent tapes is more flexible than the total width of the two adjacent lining sections, and the drums are located at different levels relative to the night, and the tapes from the upper drums 5 are placed on the soil of the tape from the bottom drums 6. As you progress, the drums are periodically charged with new rolls of tapes of flexible overlap. The device allows for the simultaneous movement of all the drums along the entire length of the lava, as well as their sequential .ku.

In the process of work, the protective parts of the lining accept different angles of inclination relative to the bottom of the lava. The distance from the protective part to the bases or the back row of the front racks can also be changed. At the same time, the barbaya 6 is due to the swivel of the frames on the axles, regardless of the poliu taken by the barrier parts (the Krepi always change directly on the soil of the lava. In the event that the drums come in contact with the bases of support or stand, we put 13 protect the device from possible damage.

Present invention

A device for laying a flexible overlap, including drums with tapes of flexible overlap, is installed on the protective part of the arm, revealing that, in order to increase the reliability of the device in operation, the drums are equipped with frames, hinged with telescopes.
