Abstract

The utility model relates to a multifunction soft combined metal mark, which is used for supporting a back side and a back roof in a mine underground. A main waste wire rope is adopted as a metal mark (back board), which effectively prevents crossing top, leaking rocks from the top board and keeps the integrity of the top board of a stope. The multifunction soft combined metal mark is an ideal support product for the back side and the back roof of the coal face of a tunnel I-bar support and a single prop matched with a metal beam for digging coal in a mine underground. The utility model has the advantages of wood saving and environment prevention, and the traditional wood make (back board) can be totally replaced by repeated action, which increases the safety degree of the coal face of the mining. The capital of 1, 319, 900 yuan can be saved in a coal road ruler per myriameter and coal mining for myriad ton as compared with the wood mark (back board). The implementation of the utility model is convenient.

Description

Multifunction soft combined metal mark

A kind of multifunction flexible combined metal mark mountain, the utility model relates to the supporting of down-hole, mine, adapts to back production, the novel supporting product on coal pick work plane back of the body group back of the body top.

The individual prop of China's middle and small scale coal mine down-hole mining work plane use at present joins metal roof bar and coal pick i iron support tunnel all is to use wooden mark yamase to help back of the body top, its tensile strength is not enough, wooden mark mountain fracture often takes place and cause the generation of leaking cash, empty top, causing roof fall dead person accident; Use wooden mark mountain, strut with the arrow beam between canopy and the canopy, do not have reciprocal interlocking, coal pick tunnel is poor because of the withstand voltage corruption in wooden mark mountain, just fracture in general about 30 days, group leakage top collapses, potential safety hazard is many, is to guarantee work plane safety, and needs two people of the every bottom class of stope lift canopy and prop up pressure, coal pick road also needs frequent maintenance, wasted material and manpower, reduced labor productivity, wooden mark mountain is disposable use, can not reclaim, in the investment, cost of ton coal increases, and has reduced the performance of enterprises, so the mountain supporting of wooden mark is used at recovery process in the colliery, and the disadvantages outweigh the advantages.

The purpose of this utility model is to provide a kind of mine down-hole supporting security performance good, replaces the new material of timber fully.

Above-mentioned purpose can reach like this: have a conical sleeve ［ 3 ］ that flexible wire rope metal material ［ 2 ］ one ends are pressed into a buckle a kind of, the other end is pressed into the circular cone adapter sleeve ［ 1 ］ of a band annulus, and two ends are all fixed with the conical wedge ［ 4 ］ that falls.Wire rope metal material ［ 2 ］ two ends with flexibility all are pressed into the conical sleeve ［ 3 ］ of buckle, when with hydraulic prop, the supporting use of metal roof bar, just with an end buckle, the wire rope flexible metallic material of one end band annulus is done the whole supporting of stope, when with the supporting use of i iron supporting, just with two ends all the wire rope flexible metallic material of buckle make the coal road back of the body group back of the body and push up whole supporting.

The utility model is compared with known technology, has various advantages:

1, it is big to have flexible rigidity and tensile strength, and security performance is good;

2, have replacement timber, repeatedly use, every myriametre coal road drilling depth and ten thousand tons of back production coals can be economized on the use of funds 131.99 ten thousand yuan;

3, protection environment, the favourable ecological homeostasis.

Accompanying drawing one is the utility model structural representation, the circular cone adapter sleeve of ［ 1 ］ annulus, the conical sleeve of ［ 2 ］ circular flexible metal material ［ 3 ］ buckle; ［ 4 ］ conical wedge

Accompanying drawing two is all conical sleeve schematic diagrames of buckle of the utility model two ends

Accompanying drawing three is the metal roof bar schematic diagram of the utility model buckle, hook plate ［ 6 ］ metal roof bar of ［ 5 ］ band double hook

Accompanying drawing four is the utility model exploiting field supporting schematic diagram

Wherein A is to the vertical view of representing after amplify the part.

Best enforcement of the present utility model is: utilize the existing waste steel wire rope in present mine to make (accompanying drawing one), (accompanying drawing two) shape, its wirerope diameter be 15～26 millimeters all can, length is 850 millimeters (finished products); When being used for stope, with above-mentioned ready-made (attachment figure one) finished product, allow the edge (accompanying drawing four A to shown in) of the end hook of its buckle ［ 3 ］ metal roof bar ［ 6 ］ the band double hook hook plate ［ 5 ］ on the monomer liquid pillar, one end of its band annulus ［ 1 ］ hangs on the hook of back timber ［ 6 ］ band double hook hook plate ［ 5 ］, and canopy and canopy are linked to be an integral body.Check and balance, stressed even.Squeeze moving capplce and pillar when having avoided vertically pressing and move and roof fall, do not need to lift simultaneously canopy increasing support density and guarantee exploiting field safety.During caving, because metal roof bar direction of advance institute extremely, the conical sleeve of buckle ［ 3 ］ breaks away from automatically, and the circular cone adapter sleeve ［ 1 ］ of band annulus is done universal rotation with the hook ［ 5 ］ above the metal roof bar ［ 6 ］; Reclaim simultaneously with back timber, when stope advances, use repeatedly.Generally getting six roots of sensation mark mountain is one group.When being used as coal road back of the body group back of the body top, with the finished product shown in the accompanying drawing two, two ends all are hooked in the i iron edge, form the whole supporting in tunnel, during prop drawing, because i iron pulls back with drawing hoist, the hook that the place ahead is one breaks away from i iron automatically, takes out when being placed on new pick tunnel and reuses.

Claims

1, a kind of multifunction flexible combined metal is marked the mountain, and it relates to the down-hole, mine and props up backpiece group back of the body top, and its technical characterictic is:

A, be pressed into the conical sleeve [3] of a buckle at an a kind of end with flexible metallic material [2], and end is pressed into the circular cone adapter sleeve [1] of a band annulus in addition, the conical wedge [4] that falls is fixing,

B, two ends with flexible metallic material [2] all are pressed into the conical sleeve [3] of buckle sometimes.

2, metal according to claim 1 is marked the mountain, it is characterized in that its buckle conical sleeve ［ 3 ］ and metal roof bar kissing, and the circular cone adapter sleeve ［ 1 ］ of band annulus is done universal rotation with the hook ［ 5 ］ above the metal roof bar ［ 6 ］.
