Description
Technical field
The utility model relates to the interlocking hurdle gear control setup in a kind of coal mine sloping lane transportation.
Background technology
At present, in the coal mine sloping lane transportation, collude magnifying slip for preventing that mine car from taking off, hurdle and gear interlock control apparatus are set in inclined gallery, it operates by artificial realization, when mine car arrives shelves, lifts gear, and mine car is let pass, and when mine car arrives the hurdle, lifts and blocks, and mine car passes through.The drawback of current existence: the site operation personnel is in order to follow the line of least resistance or once many by several cars, directly do not pull gear and hurdle by vehicle pass-through by operating mechanism, brings great hidden danger to safety in production.Because of the gear and interval set, trailer quantity is unrestricted, trailer very easily causes super trailer arbitrarily, causes wire cable rupture to take off and colludes magnifying slip, safety misadventure occurs.Although realized the function of holding up traffic, do not realize preferably that gear and hurdle automatically reset, can not be in all the time blocking state, the generation of also fundamentally not stopping the break rules and regulations actions such as super trailer; Field man must stand in the tunnel when operation and operate, and environment is relatively poor in the tunnel, exists certain security risk, can not realize essential safety.Biliographic data: " prevention of Major Accidents in Slope Roadway Transportation of Coal Mine ", " colliery is dynamo-electric ", the 6th phase in 2005.
Summary of the invention
In order to overcome the artificial execute-in-place of known interlocking road gear control setup, bring the defective of great hidden danger to safety in production, the utility model provides a kind of interlocking road dynamic control device that keeps out the wind, and this interlocking road dynamic control device that keeps out the wind adopts automatically control, realizes safety in production.
The technical solution of the utility model is: this interlocking road dynamic control device that keeps out the wind comprises ball valve, one end of ball valve links to each other with ventilation inlet, the other end of ball valve is through the end of filter water-segregator with the gear hand change over valve, an again end tandem of an again end of pressure valve and hurdle hand change over valve, the other end of gear hand change over valve and the other end of hurdle hand change over valve, air port tandem behind next end of hand change over valve and the gear cylinder, an again end of gear hand change over valve and the operating handle of pressure valve, one end of hurdle hand change over valve, an again end of hand change over valve and the front air port tandem of gear cylinder, one end of pressure valve and the other end tandem that keeps off cylinder, the other end of pressure valve and the other end that keeps off cylinder, the other end tandem of hurdle cylinder, an again end of gear cylinder and the other end tandem of hurdle cylinder, the 4th end of gear cylinder and the other end tandem of hurdle hand change over valve, an again end tandem of an again end of hurdle cylinder and hand change over valve, air port tandem behind one end of hand change over valve and the hurdle cylinder, the other end of hand change over valve and the front air port tandem of hurdle cylinder.
Ball valve is used for the whole process control of hand switch, and hand change over valve is used for changing the air feed direction, and pressure valve guarantees the flexible of cylinder push-rod to the cylinder voltage supply, and the cylinder of gear is used for the control gear, and the cylinder on hurdle is used for control group.Gear links to each other with the hurdle with gear respectively with the cylinder push-rod on hurdle.Open ball valve during operation, air feed enters respectively change-over valve and the pressure valve on gear and hurdle, enters cylinder by pressure valve again, and cylinder is started working.Operating handle has three gears to be used for operation, i.e. " gear ", " normally closed " and " hurdle " three gears.When operating handle was shifted gear onto and put, gear was opened, and mine car is by gear.Operating handle is shifted the position on hurdle onto, and the hurdle is opened, and shelves are closed, and mine car continues descending by the hurdle.Mine car is by behind the hurdle, and operating handle is shifted normally closed position onto or unclamped handle, keeps off and blocks and recover normally closed.Operating handle inside is provided with spring automatic reset mechanism, and after operation was finished, operating handle recovered midway location automatically, i.e. normally closed position, and gear and hurdle all are in normally off.
Utilize the existing high-pressure blast in down-hole as power, by the flexible drive gear of cylinder push-rod and holding up traffic or letting pass of hurdle, being in during because of cylinder operation has pressure condition, gear and hurdle are controlled by cylinder push-rod, have irreversibility, manually can't pull gear and hurdle, prevent the artificial car of putting.According to the actual bearer ability of winch, determine once at most traffick number, gear and column gutter are set, stop super trailer.Control box can be arranged in the chamber of down-hole, and operating personal need not to work in the tunnel, reduces the probability of injury to personnel evil.Fundamentally solve and operate against regulations, realize essential safety.
The general run of thins descending slope is larger in the transportation of inclined gallery, and length of grade is longer, and hundreds of rice being arranged even going up km of having is long.Collude the mine car downslide that disconnected rope, super trailer etc. cause in order in time to prevent mine car to take off, upward slope point on the slope arranges a gear respectively, and a hurdle is set below the slope, and gear is set according to electricity strand load-carrying capacity with interval, this distance can limit the quantity of traffick, prevents super trailer.Gear is for preventing that coupling vehicle does not enter inclined gallery, and the hurdle is used for preventing that vehicle from continuing operation downwards.
In the transportation of inclined gallery, be used for preventing that mine car from taking off the gear, the hurdle that collude magnifying slip or the super trailer pneumatic control setup of interlocking, after mine car was by gear, hurdle, the maintenance blocking state that automatically resets can be realized in gear, hurdle.
Advantage of the present utility model: (1) adopts the down-hole wind regime, and is simple in structure, easy to operate, need not power supply, safe and reliable.
(2) gear calculates by theory with column gutter, and the guarantee winch is worked in the load-carrying capacity scope, guarantees the safe operation of winch, avoids artificially surpassing trailer, stops to operate against regulations, guarantees safety in production.
(3) gear is realized interlocking with the hurdle, and operating handle automatically restored to normally closed position after operation was finished, and gear is in blocking state with the hurdle.
(4) gear and hurdle are controlled by cylinder, and cylinder is in pressure condition, when operating handle not, manually can not pull gear or hurdle, fundamentally stop artificially deliberately to break rules and regulations.
(5) pneumatic control setup is assembled in the casing, can operate in the chamber in tunnel, ensures site operation personnel's personal safety.
