Abstract

The utility model discloses a protective device for a gas pumping pipeline, and relates to the field of gas pumping pipeline auxiliary devices. The protective device solves the problems that an existing gas pumping pipeline in an underground coal mine is prone to deformation or damage due to effects of external force or internal force, and the like. The protective device is composed of an outer layer and an inner layer, wherein the outer layer is a metal protective sleeve, the inner layer is a belt layer, the metal protective sleeve is provided with first angle iron, second angle iron, third angle iron and fourth angle iron, the first angle iron and the second angle iron are welded and fixed through a plurality of flat iron rods, the second angle iron and the third angle iron are welded and fixed through a plurality of flat iron rods, the third angle iron and the fourth angle iron are welded and fixed through a plurality of flat iron rods, and the belt layer is fixed in the metal protective sleeve through a hole-penetrating tether. The protective device is simple in structure, easy to manufacture, safe, and reliable.

Description

Gas exhaust pipeline protective device

Technical field

The utility model relates to a kind of gas exhaust pipeline auxiliary device, is specifically related to a kind of gas exhaust pipeline protective device.

Background technology

Generally be to adopt iron sheet to make to the used pipeline of gas exhaust under the coal mine at present, usually the peripheral parcel of gas exhaust pipeline or colligation basketry sheet, old belt, dual anti-net and the iron wire etc. made at iron sheet are protected, but change in ahead work face and to remain the materials such as iron beam that are easy to by heavier in the canopy operation process and smash or damage distortion, sometimes the gas exhaust pipeline is also impacted by internal gas flow strength easily and is out of shape, and causes whole gas pipeline the pump drainage weak effect of gas to be caused easily the methane accumulation of work plane; If the gas exhaust pipeline is broken and causes gas leakage on the other hand, then can cause the serious accident of gas explosion.

The utility model content

The purpose of this utility model is in order to overcome deficiency of the prior art, a kind of simple in structure, easy to manufacture and safe and reliable gas exhaust pipeline protective device to be provided.

For achieving the above object, the utility model provides a kind of gas exhaust pipeline protective device to be provided with skin and internal layer, and described skin is protective metal shell, and internal layer is belt layer; Protective metal shell is provided with angle bar one, angle bar two, angle bar three and angle bar four, angle bar one is welded and fixed by some band irons with angle bar two, angle bar two is welded and fixed by some band irons with angle bar three, is welded and fixed by some band irons between angle bar three and the angle bar four; Described belt layer is fixed in the protective metal shell by the perforation tether.

The length of described angle bar one, angle bar two, angle bar three and angle bar four is 1 meter.

Described angle bar one is welded and fixed by six roots of sensation band iron with angle bar two, and angle bar two is welded and fixed by six roots of sensation band iron with angle bar three, is welded and fixed by six roots of sensation band iron between angle bar three and the angle bar four.

The beneficial effects of the utility model: gas exhaust pipeline protective device of the present utility model is simple in structure, easy to manufacture; Can effectively prevent pump drainage pipe interior stress deformation or other damage, the gas exhaust pipeline is had well cushioning effect; Belt layer can stop pump drainage pipeline made of iron and protective metal shell direct collision to produce spark simultaneously; It is convenient, reusable to install or remove, and saves cost.

Below in conjunction with accompanying drawing gas exhaust pipeline protective device of the present utility model is described further.

Description of drawings

Fig. 1 is protective metal shell structural representation of the present utility model;

Fig. 2 is cross-sectional diagram of the present utility model.

Among the figure: 1, protective metal shell, 2, belt layer, 3, angle bar one, 4, angle bar two, 5, angle bar three, 6, angle bar four, 7, band iron.

The specific embodiment

As shown in Figure 1 and Figure 2, the gas exhaust pipeline protective device of present embodiment is provided with skin and internal layer, and described skin is protective metal shell 1, and internal layer is belt layer 2; Protective metal shell 1 is provided with angle bar 1, angle bar 24, angle bar 35 and angle bar 46, angle bar 1 is welded and fixed by six roots of sensation band iron 7 with angle bar 24, angle bar 24 is welded and fixed by six roots of sensation band iron 7 with angle bar 35, is welded and fixed by six roots of sensation band iron 7 between angle bar 35 and the angle bar 46; Described belt layer is fixed in the protective metal shell by the perforation tether.The length of angle bar 1, angle bar 24, angle bar 35 and angle bar 46 is 1 meter.

The utility model can prevent outside destroy by protective metal shell 1 effectively as shell, and belt layer 2 can stop pump drainage pipeline made of iron and protective metal shell direct collision to produce spark.Protective metal shell 1 is that integral body and length are about 1 meter with belt layer 2, installs or removes easily, is movable to other local use.
