Abstract

The utility model discloses a polymer coal sliding chute which is particularly suitable for a transporting device in an underground mine. The utility model is provided with a chute body (1) which is provided with connecting holes (2). The chute body (1) is formed by the folding and the combination of multiple polymer layers (3) and glass fibre cloth (4). Both sides of the chute body (1) are provide with skirt sides (5) which are convenient for transportation and installation. The width of the chute body (1) decreases continuously in a uniform manner from a slightly wide end to a slightly narrow end. The utility model has the advantages of reliable safety performance, wear and corrosion resistance, low resistance value on a surface, light weight, quick coal sliding, long service life, low manufacture cost, convenient transportation, installation, and connection. The utility model not only saves steel for a country, but also reduces cost for a coal mine, being an ideal upgrading product for the existing vitreous enamel coal sliding chutes with steel plates.

Description

Polymer chute

The utility model relates to a kind of poly-mer coal drop that is specially adapted to the transportation of underground conditions such as mine or tunnel.

The coal drop of using under the existing mine is generally the enamelling sheet steel coal drop, its sheet resistance value exceeds standard, porcelain facing is frangible, and the steel plate corrosion resistance is poor, price is also expensive, and through test, make coal drop if use poly-mer replacement enamelling sheet steel material instead, then can improve wear-corrosion resistance, reduce sheet resistance value and reduce cost, but thing followed problem is, in order to satisfy the requirement of coal drop mechanical strength, what product thickness must be than existing enamelling sheet steel material is thick, so, if make that just keeping existing coal drop again is the identical constant structure of two ends size, then the connection between the coal drop can't be carried out; Even existing coal drop is structurally unreasonable, be unsuitable for the carrying and installation of down-hole, cause the generation of safety misadventure easily, also be necessary to be improved.

The purpose of this utility model is to provide a kind of adopt that polymeric material makes be convenient to bonded assembly between groove and the groove and be convenient to the poly-mer coal drop of down-hole carrying and installation.

The solution of this poly-mer coal drop is as follows.It still has the cell body that two ends have connecting bore, and its feature part is, cell body is formed by stacking with multilayer polymeric and alternate glass fabric between the adjacent two layers polymeric layer, the cell body both sides all have is convenient to the shirt rim that carrying and installation is used, and the width of cell body is the variation of successively decreasing uniformly continuously from an end is wide slightly to the other end slightly narrowly.

The utility model with said structure is when concrete the use, although the thickness of cell body plate is thicker than the coal drop of existing steel plate materials, but when between groove and groove, being connected, still can one be connected stackedly with another head and the tail, just note a narrow slightly endlap of coal drop is put in the wide slightly end slot of another coal drop of joining, and the connecting bore of two grooves aligned and connect bolt or the butting iron wire is just passable.During this coal drop of carrying and installation, no matter adopt machine or staff, only need hang or catch the shirt rim of cell body both sides, just can operate steadily safely.

This poly-mer coal drop meets the requirement of national MT113-85 safety performance inspection specification fully, and safety performance is reliable, wear resistant corrosion resistant, and sheet resistance value is low, and is in light weight, and the coal that slips is fast, and the life-span is long, and cost is low, carries and install easy to connect.It both had been that country saves steel, again for the colliery reduces production costs, was the desirable renewal product of existing enamelling sheet steel coal drop.

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the birds-eye view of a kind of concrete structure of the utility model;

Fig. 2 and Fig. 3 are respectively Fig. 1 left view of the present utility model and right elevation;

Fig. 4 is the A-A cutaway view Amplified image of the connection hole of cell body among Fig. 1;

Fig. 5 is the B-B cutaway view Amplified image of Fig. 2;

Fig. 6 is the connection diagram between groove and the groove.

Reference numeral among the above-mentioned figure is: 1, and cell body; 2, connecting bore; 3, polymeric layer; 4, glass fabric; 5, the shirt rim; 6, the little cover of guard aperture metal; 7, the tie bolt nut assembly.

Referring to Fig. 1, the width of cell body (1) is that left end is wide slightly, and right-hand member is narrow slightly, and from left to right, width narrows down continuously equably.Referring to Fig. 3, arcuation is made in the cross section of cell body (1) in an embodiment, but also can make scalariform or taper.Referring to Fig. 4, locate to be damaged at connecting bore (2) in order to prevent cell body (1), also can be in connecting bore (2) the little cover of embedding riveting guard aperture metal (6).Referring to Fig. 5, in this embodiment, the quantity of polymeric layer (3) is five layers, and the quantity of glass fabric (4) is four layers, and their number of plies also can be other quantity.Superimposed between polymeric layer (3) and the glass fabric (4) adopts automatic heating chemical combination to form.Glass fabric (4) is commercially available.The embodiment of the Main Ingredients and Appearance of a kind of polymeric layer (3) is that it is that raw material is made by resin sand, blue or green soap powder, french talc, silica flour, calcium carbonate and sulfuric acid.

Claims

1, a kind of poly-mer coal drop, have two ends and have the cell body (1) of connecting bore (2), it is characterized in that, cell body (1) is formed by stacking with multilayer polymeric (3) and alternate glass fabric (4) between adjacent two layers polymeric layer (3), the both sides of cell body (1) all have shirt rim (5), and the width of cell body (1) is the variation of successively decreasing uniformly continuously from an end is wide slightly to the other end slightly narrowly.

2, poly-mer coal drop according to claim 1 is characterized in that, the little cover of embedding riveting guard aperture metal (6) in connecting bore (2).
