Description
Technical field
The present invention relates to a kind of colliery with creeping into plant equipment, relate to specifically guide tracked emulsion hydraulic rig for a kind of colliery.
Background technology
Coal production enterprise is in the digging operation process of coal road, coal rock tunnel, coal mining activity face, often need to creep into the bore operations such as ,Tan water hole, roof bolting hole, coal-bed flooding hole, gas extraction hole, exploration hole, fluid injection fire-fighting hole, not only quantity is very big, position, hole is complicated, setting disperses, and labour intensity is high, operating environment is poor, safety wind is dangerous large; Therefore, develop that technical level is higher, functional characteristic is strong, unfailing performance is crept into plant equipment preferably, for guaranteeing operation quality, enhance productivity, reduce labor intensity, strengthen safety guarantee and be all of great significance.
China's coal-mine is historical with creeping into developing of plant equipment existing three more than ten years, what now formed one description is complete, functional characteristic is various creeps into machinery industry, what year manufactured creeps into mechanical product sales revenue total value up to more than 40 hundred million yuan, substantially can meet the needs of coal in China industry sustained and rapid development.But, all there is some weakness or deficiency in the existing engineering goods that creep into of China in actual use in various degree.The current production quantity of China is more, the scope of application is wider creeps into engineering goods, by power driven nature matter, can be divided into the three major types such as electrodynamic type, pneumatic type, fluid pressure type, and concrete condition is:
Electrodynamic type creeps into engineering goods: electrodynamic type creeps into engineering goods, has simple in structure, handiness, single, the supporting convenience of power, the outstanding advantage such as cheap, be current domestic usage quantity maximum creep into engineering goods.But the defects such as output torque characteristic is bad, overload capacity is poor, actual penetration rate is lower, the waterproof and dampproof difficulty in electric equipment down-hole that this class type ubiquity, particularly because of down-hole, use removal cable longer, exist the potential safety hazards such as cable failure electric leakage is hurted sb.'s feelings, igniting blasting.
Pneumatic type is crept into engineering goods: pneumatic type is crept into engineering goods, with compressed air, do power, there is system independent, safe and reliable, the output characteristics such as the moment of torsion of air motor, rotating speed are stable, the outstanding features such as production operation efficiency is higher, operation quality is better, be current domestic usage quantity more creep into engineering goods.But this class type exists and must use having under the condition of compressed air gas source, applied certain limitation, product technology performance is subject to down-hole compressed air system conveyance conduit distance, the external factors such as pneumatic equipment is how many of working affect greatlyr simultaneously, and product self also exists complicated structure, bulky heaviness, the more high defect of noise and vibration characteristic.
Fluid pressure type creeps into engineering goods: fluid pressure type creeps into engineering goods, that China's the eighties in last century develops the successfully novel engineering goods that creep into, with advanced hydraulic motor, do power, there is operating pressure high, output torque is large, supporting capacity is strong, the outstanding features such as pressure fluctuation and noise are less, add product self structure compact, small volume, weight is lighter, mobile operating is convenient, can share hydraulic power unit with hydraulic pressure development machine, can greatly reduce down-hole electric equipment quantity, energy conservation, it is the domestic first-selected type that plant equipment updates that creeps into, the accounting share of creeping at home the always full amount of having of engineering goods expands year by year.But this class type also exists must have corresponding hydraulic power unit, configuration high-pressure hose induction system, be furnished with the application conditions restrictions such as professional adjustment and maintenance personnel, and investment cost is larger; Exist hydraulic system easily heating in subsurface environment, during long-time continuous operation, very easily affect product technology performance and seal durability; Especially severe be, this class type is the choice for use mineral oil medium of working all, exist conveying mineral oil high-pressure hose very easily damaged by other underground work activity downthrusts, mineral oil leaks and can form subparticle under HTHP, with initiation fire very easily after air, coal dust in well mixes.
The present invention exists on weakness and not enough basis in the existing plant equipment of creeping into of earnest analytical study China, research and design goes out a kind of guide tracked emulsion hydraulic rig for colliery of doing power with emulsion motor targetedly, for the various bore operations that often carry out on coal road, coal rock tunnel, coal mining activity face, having the outstanding feature ，Dui coal mining enterprises such as output torque is large, supporting capacity is strong, operation quality is good, applied widely enhances productivity, reduces labor intensity, eliminates safe hidden trouble all significant.
Summary of the invention
The technical problem that quasi-solution of the present invention is determined:
The technical problem that quasi-solution of the present invention is determined is, overcome existing all kinds of deficiency or the weakness that plant equipment exists of creeping into of China, provide that a kind of to take the work emulsion motor of medium of high-water-based emulsion be power source, there is compact conformation, manoeuvrable, output torque is large, supporting capacity is strong, production efficiency is high, operation quality is good, labour intensity is low, without outstanding features such as potential safety hazards, can be for carry out all kinds of guide tracked emulsion hydraulic rigs for colliery that creep into operation on coal road, coal rock tunnel, coal mining activity face.
