A kind of crawler high-pressure water prmp room
The utility model relates to mine waterpower measure field equipment used, specifically a kind of crawler high-pressure water prmp room.
For high methane and projecting coal bed, need to take regional Firedamp precaution measures before exploitation, reduce coal seam gas-bearing capacity and eliminate its outburst hazard.Protective coat extracted and to take out coal-bed gas be in advance most economical effective regional gas control measure; the mining area (well) not possessing protective coat extracted condition must select at the end (top) slate lane layer-through drilling to take out the region outburst prevention measures of coal-bed gas in advance; the specific condition such as consider that China's most mining areas coal seam permeability is low, gas pressure is large and crustal stress is high; poor and the easily collapse hole blocking of layer-through drilling extracting result, therefore layer-through drilling need coordinate the anti-reflection measure such as hydraulic flushing in hole, fracturing.Under the shielding of rock pillar, utilize the drill bit cutting of band high pressure water and press water to wash away coal body, discharge broken coal and gas, stress is concentrated and is moved around punching, makes coal mass relief near punching anti-reflection, effectively can improve gas drainage results.At present, provide the equipment volume of high pressure water huge mobile inconvenience for underground coal mine, be difficult to meet hydraulic flushing in hole high strength hydraulic demand, manpower and materials consumption is large.
Model utility content
The purpose of this utility model is to provide a kind of crawler high-pressure water prmp room, water tank, power take-off, water supercharging device are integrated on crawler travel platform, and in conjunction with the feature under mine, the locations of structures relation of each assembly is optimized, can in space under mine move operation convenient, to use manpower and material resources sparingly, improve waterpower measure efficiency.
In order to solve the problems of the technologies described above, the technological scheme that the utility model adopts is: a kind of crawler high-pressure water prmp room, comprise crawler body, motor, high-pressure water pump, travel control valve and cistern assembly, wherein crawler body is by traveling crawler, oil hydraulic motor and bottom girder composition, described motor is fixed on one end of crawler body, the other end of crawler body is fixedly installed cistern assembly, cistern assembly is by water tank, water inflow filter, water inlet float valve, water intake ball valve, level meter and stop valve composition, water inflow filter is arranged on the water intake pipeline of water tank, and water inlet float valve is set inside water intake, the water intake of water inflow filter arranges water intake ball valve, described level meter is arranged on tank box, described high-pressure water pump is arranged between water tank and described motor, and be connected by described stop valve between the water intake of high-pressure water pump and the water outlet of described water tank, the elastic coupling flexible coupling being connected motor output end and high-pressure water pump is respectively set between motor with high-pressure water pump, described travel control valve is arranged on the crawler body of motor side, and be connected with described oil hydraulic motor.
Further, described high-pressure water pump adopts high pressure plunger water pump.
Further, described oil hydraulic motor is hydraulic oil motor or emulsion motor.
Compared with prior art, the utility model has following beneficial effect:
Each device compact in design of the utility model, rationally, space utilization is effective, the movement that high-pressure water pump stands in underground coal mine can be met, and just can control the movement of whole pumping plant fast and flexible due to the handle by travel control valve, therefore greatly reduce the labor intensity of workman, and this high-pressure water prmp room can export the current of 200L/min and the pressure of 20MPa.

Below in conjunction with accompanying drawing, by embodiment, the utility model is further described.
As shown in the figure, a kind of crawler high-pressure water prmp room, comprise crawler body 1 and be fixedly installed on the motor 2 on crawler body 1 respectively, high-pressure water pump 3, travel control valve 4 and cistern assembly 6, crawler body 1 is by Caterpillar walking wheel, oil hydraulic motor 101 and bottom girder composition, wherein, described travel control valve 4 is arranged on the valve fixing frame of one end of crawler body 1, and be connected with described oil hydraulic motor 101, the walking of whole pumping station can be controlled by this oil hydraulic motor 101, described motor 2 is bolted on travel control valve 4 with on the crawler body 1 of one end, and motor 2 and travel control valve 4 side-by-side parallel are arranged, described cistern assembly 6 is fixed on the other end of crawler body 1, described high-pressure water pump 3 adopts high-pressure plunger pump, be fixed in the middle part of crawler body 1, namely between cistern assembly 6 and motor 2, and elastic coupling flexible coupling 5 is set between motor 2 and high-pressure water pump 3, by elastic coupling flexible coupling 5 by motor 2 Power output, high-pressure water pump 3 is driven to work.
Be fixed on bottom water tank 601 in described cistern assembly 6 on crawler body 1, the water outlet of water tank 601 is communicated with by the water intake of pipeline with high-pressure water pump 3, and stop valve 606 is set on this pipeline, the arranged outside water inflow filter 602 of water tank 601 water intake, inner side arranges water inlet float valve 603, for automatically controlling the water inlet of water tank 1, the feed-water end of described water inflow filter 602 arranges water intake ball valve 604, and water tank 1 sidewall is provided with the level meter 605 observing water level.
Carry out in operation process utilizing the utility model, when the mobile pumping station of needs, travel control valve 4 pressure oil is supplied by the external world, and handle travel control valve 4 handle, make the oil hydraulic motor on crawler body 1 obtain pressure oil, and then realize the advance of whole pumping plant in underworkings or retrogressing by oil hydraulic motor.
Be more than basic embodiment of the present utility model, can do on above basis and further improve or limit:
As, described motor 2 and high-pressure water pump 3 are integrated on crawler body 1, reach conveniently moving flexible.
As, the oil hydraulic motor on described crawler body 1 can provide pressure oil by the external world, also can arrange oil hydraulic pump to provide pressure oil on this pumping plant.
And for example, described oil hydraulic motor is oil motor, and also replaceable is emulsion motor.
For another example, under the condition that mine laneway cross-section size allows, length and the width of crawler body can be increased, increase high-pressure water pump and capacity motor simultaneously.
