Abstract
The utility model relates to an internal spray system used in a fully-mechanized coalface coal mining machine in a coal mine, belonging to a key component in the coalface coal mining machine in the coal mine, which aims at solving the problem of the gear box oil-liquid emulsification caused by water leakage in the prior art. The internal spray system is provided with a water inlet, a swivel joint, a water pipe and a water outlet; wherein, one end of the water pipe is provided with the water outlet and the other end of the water pipe is movably connected with the swivel joint; the connecting part of the water pipe which oppositely rotates and the swivel joint is arranged on the outside of the gear box body of the rocker-arm planetary reduction gear of the coal mining machine; the swivel joint is provided with the water inlet; the water pipe is communicated with the water inlet through the swivel joint. The internal spray system is different from the present domestic and international internal spray system of the coal mining machine that the swivel connecting part of the spray waterway is arranged on the outside of the gear box body of a cutting rocker-arms planetary reduction gear, therefore, when the rotary sealing part occurs leakage, the water flows to the outside of a shell body rather than a cavity body.
Description
Technical field
The utility model relates to a kind of internal spraying system that is used for the coal mine fully-mechanized mining working coal-winning machine, belongs to the key components and parts of coal mine work area coal-winning machine.
Background technology
Coal-winning machine is the core equipment of coal mine machinery coal mining, and it and drag conveyor, the supporting use of support apparatus can realize the efficient output of coal.The reliability effect of coal-winning machine the efficient of mechanical coal mining, traditional coal-winning machine internal spraying system is owing to be rotatably connected part in the gear cavity, in time, has because of water enters the gear cavity and causes the fluid emulsion, influenced the use of coal-winning machine, even can cause scrapping of some component.Therefore, for fundamentally solving above-mentioned technical barrier, the generation of thoroughly stopping this type of fault is necessary to design a kind of novel coal-winning machine internal spraying system.
The utility model content
The purpose of this utility model is to provide a kind of internal spraying system that is used for the coal mine fully-mechanized mining working coal-winning machine, solve exist in the prior art hidden danger---water enters and causes the fluid emulsification problem in the gear cavity.
The technical solution of the utility model is:
The internal spraying system that is used for the coal mine fully-mechanized mining working coal-winning machine, this internal spraying system is provided with water inlet, swivel joint, water pipe, delivery port, water pipe one end is provided with delivery port, the water pipe other end is connected with swivel joint, counterrotating water pipe and swivel joint junction are arranged at outside the gear housing of rocker arm of coal mining machine planetary reduction gear, swivel joint is provided with water inlet, and water pipe is communicated with water inlet by swivel joint.
Described internal spraying system, water pipe is connected with the rotating part of rocking arm planetary reduction gear by clamp I; the standing part installed inside of rocking arm planetary reduction gear has holder; swivel joint is fixed by clamp II and holder one end; the holder other end is installed gland, and holder rotates by bearing is relative with water pipe.
Described internal spraying system is provided with rotatory sealing between gland and the water pipe, and water pipe is being provided with dust ring with the swivel joint link.
The beneficial effects of the utility model are:
1, the junction (being relative rotating part) of internal spraying water pipe and swivel joint in the utility model, and swivel joint places outside the gear housing of rocking arm planetary reduction gear, water inlet is arranged on the swivel joint, water pipe is communicated with water inlet by swivel joint, when rotating part seal failure or other reason cause the junction to take place to leak, the unlikely water inlet of the gear housing of reducer.
2, the utility model has adopted swivel joint to be connected with water pipe, can relatively rotate between the two, with the relative rotation between the gear housing that guarantees water pipe and rocking arm planetary reduction gear.
3, the utility model swivel joint can adopt standard swivel joint or self-control swivel joint, guarantees to satisfy the water under high pressure sealing and get final product under rotation status, and its processing and manufacturing is simple, and operation and maintenance is convenient.
Description of drawings
Fig. 1 is the utility model coal-winning machine internal spraying system component assembling figure.
Among the figure, 1 delivery port; 2 rotating parts; 3 water pipes; 4 glands; 5 standing parts; 6 clamp II; 7 holders; 8 water inlets; 9 swivel joints; 10 dust rings; 11 bearings; 12 rotatory sealings; 13 clamp I.
The specific embodiment
As shown in Figure 1, the coal-winning machine internal spraying system is provided with delivery port 1, rotating part 2, water pipe 3, gland 4, standing part 5, clamp II 6, holder 7, water inlet 8, swivel joint 9, dust ring 10, bearing 11, rotatory sealing 12, clamp I 13 etc., what rotating part 2 and standing part 5 were represented is the output and the casing fixed end of rocking arm planetary reduction gear, because this two-part relative rotation, must guarantee to have whirligig between water inlet 8 and the delivery port 1 from designing, carry in order to guarantee the water under high pressure under the rotation status.Wherein: water pipe 3 one ends are provided with delivery port 1, water pipe 3 other ends are connected with swivel joint 9, counterrotating water pipe 3 is arranged at outside the gear housing of rocker arm of coal mining machine planetary reduction gear with swivel joint 9 junctions, water pipe 3 is being provided with dust ring 10 with swivel joint 9 links, swivel joint 9 is provided with water inlet 8, and water pipe 3 is communicated with water inlet 8 by swivel joint 9; Water pipe 3 is fixedlyed connected with the rotating part 2 of rocking arm planetary reduction gear by clamp I 13; standing part 5 installed inside of rocking arm planetary reduction gear have holder 7; swivel joint 9 is fixed with holder 7 one ends by clamp II 6; holder 7 other ends are installed gland 4; be provided with rotatory sealing 12 between gland 4 and the water pipe 3, and holder 7 is realized rotation by bearing 11 and water pipe 3.
The utility model is installed on standing part 5 with swivel joint 9, by holder 7 gear housing of swivel joint 9 with reducer separated, water pipe 3 and swivel joint 9 two-part relative rotations have been guaranteed simultaneously again, the relatively fixed part that clamp I 13 among Fig. 1 and clamp II 6 have fixed water pipe 3 and swivel joint 9 respectively guarantees two-part rotation by bearing 11.
Water under high pressure enters swivel joint through water inlet, again through the water pipe with the coal mining machine roller rotation, is sent into the spray water piece of coal mining machine roller then by delivery port, realizes spraying; As can be seen from the figure, two places of water pipe be tightly connected (rotatory sealing 12, dust ring 10) all be located at outside the gear housing of reducer, therefore, leak by sealing place in case water under high pressure takes place, the utility model can guarantee that the water that sprays does not flow in the gear housing.
