Technical field
The utility model relates to a kind of cooling of charge system for coal mining machine in full-mechanized mining face, is used for realizing the increase of coal-winning machine cooling water pressure.
Background technology
Coal-winning machine is the nucleus equipment of fully-mechanized mining working, and itself and hydraulic support, scratch board conveyor support the use, and major function is cut coal seam, and coal cinder is dropped on transporter.Cooling spray system is the important component part of coal-winning machine, during coal-winning machine work, cylinder will produce a large amount of coal dusts in cut and the process of coalingging, and this has not only reduced the visibility of work plane, impact is normal produces, and safety in production and workman's health also can be produced and be had a strong impact on.Therefore depositing dust in time, reduces airborne dustiness to greatest extent, and coal-winning machine is when work simultaneously, and each critical piece (as motor, automatically controlled transformer, rocking arm etc.) produces very large heat, must carry out in time cooling, to guarantee that coal-winning machine normally works.
The press water that coal-winning machine cooling spray system is used ore deposit side to provide, in use, due to reasons such as linear loss and leakages, when coal-winning machine is normally worked, the pressure of cooling water does not often reach designing requirement, and dedusting and cooling effect are poor, need to carry out supercharging to cooling water.Conventional boosting method adopts booster pump and negative pressure booster mode mostly at present, complex structure, and larger to system change, cost is higher.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of coal-winning machine cooling of charge system simple in structure, with low cost.
In order to solve the problems of the technologies described above, the coal-winning machine cooling of charge system that the utility model provides, comprise cooling water inlet pipeline, described cooling water inlet pipeline is parallel with the first pipeline and the second pipeline, the first described pipeline is connected with the import of booster pump, described supercharging delivery side of pump connects an entrance point of shuttle valve, another entrance point of described shuttle valve is connected with the second described pipeline, the port of export of described shuttle valve connects coolant outlet pipeline, and power transmission shaft and the drive unit of described booster pump are in transmission connection.
Described drive unit is hydraulic motor.
Booster pump is centrifugal pump.
Adopt the coal-winning machine cooling of charge system of technique scheme, it has following essential characteristics and obvious advantage:
1, the motor-mount pump device that the utility model adopts is directly connected with booster pump by hydraulic motor, by motor driving booster pump, rotated, and compact conformation, transmission efficiency is high.
2, the pressure oil of the utility model by hydraulic control oil circuit provides power for hydraulic motor, and on pipeline, electromagnetic valve is housed, and the unlatching of controllable motor pump installation, stops.
3, the booster pump in motor-mount pump device of the present utility model is arranged in cooling water pipeline, by its work, can make cooling water pressure raise, and improves spraying, cooling effect.
4, the utility model is equipped with shuttle valve in cooling spray system, can guarantee the lasting circulation of cooling water.
5, the utility model does not change the internal construction of coal-winning machine, can realize plug and play, and mounting method and installation site can according to circumstances be selected arbitrarily.
In sum, the utility model is a kind of coal-winning machine cooling of charge system simple in structure, with low cost.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Referring to Fig. 1, cooling water inlet pipeline 10 is parallel with the first pipeline 8 and the second pipeline 9, the first pipeline 8 is connected with the import of booster pump 5, booster pump 5 is centrifugal pump, the outlet of booster pump 5 connects an entrance point of shuttle valve 7, another entrance point of shuttle valve 7 is connected with the second pipeline 9, the port of export of shuttle valve 7 connects coolant outlet pipeline 6, the power transmission shaft of booster pump 5 and hydraulic motor 4 are in transmission connection, booster pump 5 and hydraulic motor 4 form motor-mount pump device 3, and the drive system of hydraulic motor 4 adopts electromagnetic valve 2 to be connected with fluid pressure line 1.
Referring to Fig. 1, fluid pressure line 1 is connected with coal-winning machine oil circuit control, and electromagnetic valve 2 is housed on fluid pressure line 1, can control the break-make of fluid pressure line 1.
As shown in Figure 1, when booster pump 5 work, the cooling water of cooling water inlet pipeline 10 flows through shuttle valve 7 by the first pipeline 8, booster pump 5 and enters coolant outlet pipeline 6, for cooling system provides cooling water, when booster pump 5 is not worked, the cooling water of cooling water inlet pipeline 10 directly flows through shuttle valve 7 by the second pipeline 9 and enters coolant outlet pipeline 6, for cooling system provides cooling water.
As shown in Figure 1, motor-mount pump device 3 is comprised of hydraulic motor 4 and booster pump 5, and hydraulic motor 4 is arranged in fluid pressure line 1, and booster pump 5 is arranged in the first pipeline 8, and hydraulic motor 4 drives booster pump 5 to rotate.
The course of work of the present utility model is as follows: when coal-winning machine cooling water pressure is not enough, press electromagnetic valve 2, pressure oil drives hydraulic motor 4 to rotate through fluid pressure line 1, thereby drive booster pump 5 work, booster pump 5 raises the cooling water pressure in the first pipeline 8, through shuttle valve 7, enter cooling system, for coal-winning machine provides the cooling water that pressure is higher; When cooling water pressure meets the demands, motor-mount pump device 3 is not worked, and cooling water enters cooling system through the second pipeline 9 by shuttle valve 7.Shuttle valve 7 can guarantee still do not have cooling water to flow through when booster pump 5 is not worked.
The utility model drives booster pump 5 to rotate by hydraulic motor 4, thereby realizes the rising of cooling water pressure.
The power source of hydraulic motor 4 is provided by coal-winning machine self hydraulic system, does not need external connection power source.
The break-make of hydraulic motor 4 is controlled by electromagnetic valve 2, can select as required whether cooling water to be carried out to supercharging.
Compact overall structure, can be arranged on coal-winning machine inside, uses reliable, easy to maintenance.
