Description
Technical field
Mining elevator braking hydraulic station is the utility model is related to, particularly a kind of double double-stage braking hoister hydraulics
Stand, be particularly suitable for use in Mine Incline Hoist.
Background technology
Mine hoist braking is that oil-break brakes with the operation principle of hydraulic station, does not have oil pressure then at disc type lock in disc type lock
In applying lock state, this to apply lock mode more safe and reliable.Why two stage braking in emergency circumstances is carried outBecause disk
The design braking moment of formula lock is according to actual three times for maximum actual statical moment of standard.If in emergency situations, carry out one
All locks, are in complete on-position, then can produce very big deceleration, to steel wire rope and set by level braking quickly
It is standby to cause very big impact, or even can damage, easily there is accident.So to carry out two stage braking, make elevator relative
Smoothly brake, it is ensured that equipment and the safety of personnel, so two stage braking is a safety precautions.
But when existing common double-stage braking hoister hydraulic station is used for incline hoist, there are the following problems：If
Two stage braking is normal in weight decentralization process, can operate very well, but if it is urgent that two level is carried out during upper put forward
Braking is just certain to cause slack rope accident.Because the setting of two stage braking be according to equipment magnitude of load in a fully loaded state come
Determine, if deceleration is excessive during above carrying, due to above carrying process steel wire rope category compliant member, it is impossible to pressure is born,
It can be bent in the presence of pressure, transient rise machine just stops operating, and the mine car above carried can rush one upwards in the presence of inertia
Segment distance just stops, so, steel wire rope between elevator and cage will Panasonic come, next in the effect of gravity
Under, mine car can move round about, as a result stretch steel wire rope in an instant, and steel wire rope can bear very big pulling force, so as to
Steel wire rope or even whole equipment can be caused damage, the sport car thing that consequence is quite serious can be caused if steel wire rope is pulled off
Therefore.
The content of the invention
The purpose of this utility model is to provide for a kind of double double-stage braking hoister hydraulic stations to solve the above problems, its
It is reasonable in design, using reliable, to raise and decentralize the two stage braking pressure that cage provides different suitable operating modes, make inclined shaft
Elevator it is upper carry cage during can also realize stable brake hard.
The technical solution of the utility model is：

Pressure transmitter 24.Smart oil filter 25 and unidirectional is respectively equipped with the disc-brake B pipes 28 and disc-brake B ' pipes 29
Valve 26.
Operation principle：
During normal work, except two stage braking with magnetic valve G4 13 is to determine to lead to according to the specific operating mode for above carrying or transferring
Power-off, remaining magnetic valve are all powered.Main motor 6 rotates, and hydraulic oil enters hydraulic pump 5 by oil-suction oil filter 4, then passes through
Smart oil filter 7 reaches working connection 8, and pressure at this moment is controlled by proportional pressure control valve 10, if wanting pressure to rise, is reduced by ratio
The spillway discharge of overflow valve 10, if it is desired that pressure declines, just increase the spillway discharge of proportional pressure control valve 10.This pressure passes through pressure
Table II 21 is observed that.Because magnetic valve G3 19 and magnetic valve G3 ' 20 (parallel connection) are in "on" position, the pressure in working connection 8
Power oil arrives check valve 26 by magnetic valve G3 19 and magnetic valve G3 ' 20, then enters disc-brake B by high-pressure stop valve 27
Pipe 28 and disc-brake B ' pipes 29 (being a pipe in fact), reach disc-brake from this two pipes, beat disc-brake
Open, elevator is started working.At this moment the course of work for opening a sluice gate and applying lock is just controlled by proportional pressure control valve 10.When applying lock, by
Decline in pressure, the oil of hydraulic station is returned to by check valve 26, smart oil filter 25, magnetic valve G3 19 and electricity from disc-brake
Magnet valve G3 ' 20, proportional pressure control valve 10 return to fuel tank 1.
While elevator normal work, pressure oil flows through check valve 15, into accumulator by the decompression of pressure-reducing valve 14
16, pressure at this moment can be read by pressure gauge I 17.The pressure of accumulator 16 is to determine operating pressure with required high pressure
, it means that the no pressure oil of orifice plug 18 is by but in decentralization process, because two stage braking pressure is less than during above carrying
The pressure of pressure oil in accumulator 16, pressure oil can be by orifice plug 18, decentralization two stage braking overflow valves 11 to the overflow of fuel tank 1.
Orifice plug 18 serves the effect for avoiding losing excessive reservoir pressure oil herein.
In case of emergency, when carrying out two stage braking, main motor 6 is stopped operating, and the pressure in working connection 8 is overflow for ratio
The residual voltage of valve 10 is flowed, this residual voltage can cause hydraulic pump 5 to invert, so as to cause hydraulic pump 5 to damage and noise, so in oil circuit
Add relief valve G6 9, when main motor 6 stops operating, it is also powered off, and residual voltage lets out oil return box 1 by relief valve G6 9, at this moment with
The check valve 15 that accumulator 16 communicates works, and cut-out contacts with working connection 8.
The pressure oil of disc-brake comes magnetic valve G3 19 and magnetic valve G3 ' by check valve 26 and smart oil filter 25
At 20, at this moment magnetic valve G3 19 and magnetic valve G3 ' 20 have been powered off, and pressure oil is used by two stage braking by the two most
Magnetic valve G4 13 and accordingly gate above carry two stage braking overflow valve 12 or decentralization two stage braking overflow valve overflows 11 oil return boxes 1, by
In the effect of orifice plug 18, accumulator 16 receives the impact of very little, and a sub-fraction hydraulic oil flows into accumulator 16, makes accumulation of energy
The pressure of device 16 reaches two stage braking pressure, and at this moment overflow has been completed, and the pressure of whole disc-brake is controlled in two-stage system
Dynamic pressure force value, leaked by accumulator 16 come replenishment system, so as to maintain two stage braking pressure.When the two stage braking time to after,
Or elevator has stalled, at this moment magnetic valve G5 23 and magnetic valve G5 ' 22 is powered off, and releases the two-stage system dynamic pressure in disc-brake
Power, disc-brake all reaches applies lock state completely, and two stage braking (safety arrestment) terminates.
