Description
Technical field
The utility model belongs to technical field of mining underground auxiliary transportation equipment, and in particular to one kind has electro-hydraulic coordination
The colliery suction-type sewer scavenger of soil pick-up control function.
Background technology
For underground coal mine during coal mining, underground water and backwater finally flow into sump entrainment of broken coal and other debris, production
Raw a large amount of sediments.Since sump is the main place of colliery central drainage, to ensure that colliery normally produces operating, and carry out prominent
Water and the work of rainy season disaster prevention, it is necessary to periodically clear up sump.
Currently used sump cleaning method has four kinds, including：
（1）Artificial dredging：Sediment is shoveled into upper engineering truck with spade and transports to ground again, this method occupancy personnel are more, work
Intensity is big, and mine easily omits mud ponding on the way up and down, causes environmental pollution；
（2）Using sewage pump：Sediment is directly drained into ground from underground with dredge pump and pipeline, but is worn after use
Seriously, pipeline is easily blocked and can not cleared up.
（3）Jet pump and slush pump joint cleaning：Sediment is broken into rapidly by mud using jet pump, by mud pumping
By pipeline to ground after taking, but the arrangement installation of the program is more difficult, and the turnaround time is longer；
（4）Explosion-proof loader combines cleaning with anti-explosion engineering car：With explosion-proof loader by anti-explosion engineering car on the shovels such as coal slime
Ground is transported to, it is necessary to which two kinds of vehicles are used cooperatively；
Therefore, it is necessary to a kind of colliery suction-type sewer scavenger that can be cleared up sump but also transport sludge is equipped with, to simplify underground
Vehicle configuration, significantly improve work efficiency.
For underground coal mine auxiliary conveying equipments, the problem of security is overriding concern.If vehicle advances or retreats
Occurring maloperation during traveling lifts dirt-absorption tank, and in head-room, lower ground collision accident just occurs in side；If inhale
Occurring maloperation during dirt makes Vehicular turn or driving, it is possible to causes soil pick-up operating personnel's injures and deaths.Therefore, suction-type sewer scavenger
Driving system and sewage sucking system should be independent and mutual lockings.At present, the suction-type sewer scavenger on road surface there is no driving and soil pick-up mutual
Blocking function, in the suction-type sewer scavenger of underground, such as China authorizes public number to elaborate a kind of underground for the patent of invention of CN 104500135A
The driving of suction-type sewer scavenger and lifting combined control system, connection of the system by gear selecting control valve to gear selecting cylinder and explosion-proof solenoid valve
Dynamic control, realizes that elevating ram ability is active when vehicle be in drive shift elevating ram can not act when driving, vehicle is in neutral gear
Work energy, but the system, there are deficiency at two, one is free from the mutual blocking function that reverse drive gear is driven a vehicle and lifted when driving, deposits
Collision hidden danger is lifted in dirt-absorption tank, function is implemented in two linkages for being free from vehicle parking during soil pick-up operation, hidden there are car slipping
Suffer from.Except driving and sewage sucking system lack mutual locking, suction-type sewer scavenger also has safety issue on fire.If engine high-temperature or
There is spark and does not obtain timely processing in surrounding, it is possible to causes on fire or deflagration accident, but engine is often empty in closing
In, driver is with the naked eye not easy to monitor fire behavior, when fire behavior is obvious driver just get off taking-up fire extinguisher put out a fire, it is past
It is past just to miss the best opportunity.Therefore, it is necessary to a kind of explosion-proof automatic fire extinguishing system is equipped with, the fire near real-time detection engine
Feelings, once finding that fire behavior can spray dry powder automatically and put out a fire, both effectively prevent equipment property loss, have also ensured personnel people
Body safety.And it is current, the suction-type sewer scavenger of road surface and underground does not possess automatic fire-extinguishing function.
No matter what kind of increasingly automated level is equipment reached, and people is in leading position all the time, so personnel's comfort
And underground coal mine auxiliary conveying equipments to be considered.The driver's cabin energy hermetic section noise of closing and sleet dust haze etc. are severe
External environment condition, subsidiary heater can be windshield dehumidification, also can bring comfort in severe cold weather for driver, this
All embody application of the ergonomics in underground coal mine auxiliary conveying equipments a bit.
Under regular situation, suction-type sewer scavenger needs driver stands in dirt-absorption tank forward observation form when working, when dirt reaches in tank
During to form designated position, vacuum pump is immediately closed off, otherwise dirt may proceed to suction vacuum pump pipeline and vacuum pump, and damage is true
Sky pump.Underground coal mine light is weaker, and using repeatedly after, the form of dirt-absorption tank be contaminated cause it is smudgy, therefore observation regard
Window is unpractiaca.Anti-overflow valve, i.e. float check valve apparatus are housed at the top of some dirt-absorption tanks, when the fast canful of soil pick-up, float will
Check valve top to and close air entry, so as to effectively prevent dirt suction vacuum pump pipeline and vacuum pump, but if vacuum pump after
Reforwarding turns, and will inhale the thin pipeline of wall flat or suction through, so as to cause damages.So it is necessarily increased during soil pick-up operation a kind of anti-
Excessive function, when soil pick-up fast canful, vacuum pump is automatically stopped operating, without driver's Real Time Observation form, also protects vacuum pump
Pipeline and vacuum pump.
Common suction-type sewer scavenger can only the preferable dirt of suction mobility, it is poor to sump flows, grain density is larger
Sediment, suction effect is very poor.Some suction-type sewer scavengers hang down stirring-head in the fixed agitating device of tank body rear portion setting, soil pick-up
Disposed upright, which enters in cesspool, first stirs dirt to aspirate again, improves soil pick-up efficiency, but can not reach sump mouth in vehicle
In the case of, which does not work.So suction-type sewer scavenger is necessary configuration easily Mobile hand-held agitating device, have
Larger operating radius, when vehicle can not be reached near sump, the hand-holdable stirring-head of staff is played with dirt sucking tube one
Up to sump mouth, while implement stirring and soil pick-up action, so as to improve pumping efficiency.
