And electromagnetic type reversal valve 3 selects three position four-way directional control valve, hand reversal valve 4 selects two-position four way change valve, electricity
The A hydraulic fluid port of magnetic-type reversal valve 3 and the K hydraulic fluid port of hand reversal valve 4 are connect with the rod chamber of the oil cylinder 51 of two safety tongs 5,
The B hydraulic fluid port of electromagnetic type reversal valve 3 and the L hydraulic fluid port of hand reversal valve 4 connect with the rodless cavity of the oil cylinder 51 of two safety tongs 5
It connects, the M hydraulic fluid port of the P hydraulic fluid port of electromagnetic type reversal valve 3 and hand reversal valve 4 shakes the pressure oil valve of hydraulic mechanism 13 with two respectively
137 oil outlet connection, the P hydraulic fluid port of electromagnetic type reversal valve 3 and the M hydraulic fluid port of hand reversal valve 4 are hydraulic with two vibrations respectively
The oil outlet of the pressure oil valve 137 of mechanism 13 connects, in addition, the M hydraulic fluid port of the P hydraulic fluid port of electromagnetic type reversal valve 3 and hand reversal valve 4
It is also connect with accumulator 2, the P hydraulic fluid port of electromagnetic type reversal valve 3 and the M hydraulic fluid port of hand reversal valve 4 also pass through oil with fuel tank 7
Pipe connection, and the oil outlet for shaking the pressure oil valve 137 of hydraulic power source 1 is also connect with accumulator 2 by oil pipe, oil sucting valve 136 into
Hydraulic fluid port is connect with fuel tank 7 by oil pipe, and in order to increase safety, accumulator 2 is also connect by overflow valve 8 with fuel tank 7.
On the other hand, the commutation control of the travel switch 644 of pneumatic limiter of speed 6 and solenoid directional control valve 3 is electrically connected, that is, is worked as
When travel switch 644 transmits a signal to solenoid directional control valve 3, solenoid directional control valve 3 can accordingly commutate.
The present invention is in use, upper plate 11 can be mounted on car frame by bolt, and the driving wheel energy and carrying roller of elevator
15 are connected by wirerope, and upper plate 11 is fixed at this time, and lower plate 12 can make certain movement, and the oil cylinder 51 of safety tongs 5 is mounted on
On car frame, two safety blocks 53 are separately mounted to the two sides of carriage, and on cage guide, hand-operated direction valve 4 is changed
It is mounted in carriage to handle, hand-operated direction valve 4 is in left position by spring force, and the mounting plate 65 of pneumatic limiter of speed 6 is passed through
Bolt is mounted in carriage, and other Hydraulic Elements may be mounted in hydraulic station, and solenoid directional control valve 3 is in middle position, at this point,
Safety tongs 5 does not work.
When elevator work, carrying roller 15 is drawn by driving wheel, and carriage moves up and down, when moving due to carriage
It will do it certain vibration, so that carrying roller 15 also will do it certain vibration, the power that carrying roller 15 shakes is acted on by axis 14
In lower plate 12, lower plate 12 also makees certain vibration, and the first spring 131 can hold lower plate 12 when lower plate 12 shakes, so
Lower plate 12 can move up and down in a certain range, then the pull rod 132 fixed with lower plate 12 also can be in a certain range
It moves up and down, and since plunger 134 is contacted with pull rod 132, and plunger 134 is limited by second spring 133, so column
Plug 134 can also move up and down in a certain range with pull rod 132.
When plunger 134 moves downward, the space in valve body 135 increases, and the inside pressure is reduced, the spool of oil sucting valve 136
It is opened by atmospheric pressure, oil sucting valve 136 is from draw oil in fuel tank 7 and is stored in valve body 136, and when plunger 134 is transported upwards
When dynamic, the space in valve body 135 reduces, and the inside pressure increases, and the spool of pressure oil valve 137 is opened by atmospheric pressure, and pressure oil valve 137 will
Hydraulic oil in valve body 135 is forced into accumulator 2, and since carrying roller 15 is in carriage moving process, the continuous earthquake motion of meeting,
Therefore plunger 134 also can constantly move up and down by hydraulic oil storage into accumulator 2, that is, store energy to accumulator 2
In, and when the hydraulic oil stored by accumulator 2 is excessive, then overflow valve 8 can be opened, so that a part of hydraulic oil of accumulator 2
It returns in fuel tank 7.
Meanwhile when carriage up/down is mobile, carriage will drive pneumatic limiter of speed 6, and up/down is mobile together, and up/down is moved through
The air-flow generated in journey can by air hose 62 it is upper below the hole 631 of ventilating board 63 enter in air hose 62, and pass through balloon
After 61, from air hose 62 it is lower above the hole 631 of ventilating board 63 flow out, and up/down side enters airflow function on balloon 61,
Will push balloon 61 and carry out lower/upper movement, but the mobile balloon 61 of up/down can be pulled by connecting rope 67 be located at it is lower above
The sliding seat 642 of switch 64 is mobile, and makes to compress the spring 643 of inductive switch 64.
When carriage is in normal speed, since the size of air-flow is limited, the movement of balloon 61 is limited, the pressure of spring 643
In a certain range, so that 642 moving distance of sliding seat is also limited, sliding seat 642 will not touch travel switch 644, i.e., for contracting
Solenoid directional control valve 3 maintains vacancy, and safety tongs 5 does not work, carriage normal movement.
And when the speed of carriage overruns, air-flow can increase accordingly, and the mobile range of balloon 61 increases, switch
64 spring 643 is further compressed, and the moving distance of sliding seat 642 increases and touches travel switch 644, then travel switch
644 transmit a signal at solenoid directional control valve 3, and solenoid directional control valve 3 changes to left position.At this point, the rod chamber of the oil cylinder 51 of safety tongs 5 into
The hydraulic oil that oil, rodless cavity oil return, the i.e. hydraulic oil of accumulator 2 and vibration hydraulic mechanism 13 are extruded when shaking, can all pass through
Solenoid directional control valve 3 enters the rod chamber of oil cylinder 51, and the hydraulic oil in rodless cavity is returned in fuel tank 7 by solenoid directional control valve 3, oil
The piston rod of cylinder 51 retracts, and the piston rod of oil cylinder 51 pulls safety block 53 by connecting rod 52, safety block 53 clamp guide rail with
Brake carriage.
After the troubleshooting of carriage, solenoid directional control valve 3 only need to be switched to right position, the oil cylinder 51 of safety tongs 5 without bar
The hydraulic oil that chamber oil inlet, rod chamber oil return, the i.e. hydraulic oil of accumulator 2 and vibration hydraulic mechanism 13 are extruded when shaking passes through electricity
Magnetic reversal valve 3 enters the rodless cavity of oil cylinder 51, and the hydraulic oil in rod chamber is returned in fuel tank 7 by reversal valve 3, oil cylinder 51
Piston rod is overhanging, and loosens safety block 53 by connecting rod 52, and safety block 53 does not reclamp guide rail.
On the other hand, if user is when taking elevator, discovery elevator has any special status, can pull manual reverse of direction
Hand-operated direction valve 4 is switched right position by the commutation handle of valve 4, at this point, the rod chamber oil inlet of the oil cylinder 51 of safety tongs 5, rodless cavity is returned
The hydraulic oil that oil, the i.e. hydraulic oil of accumulator 2 and vibration hydraulic mechanism 13 are extruded when shaking, can all pass through hand-operated direction valve 4
Hydraulic oil into the rod chamber of oil cylinder 51, and in rodless cavity is returned in fuel tank 7 by hand-operated direction valve 4, the piston of oil cylinder 51
Bar retracts, and the piston rod of oil cylinder 51 pulls safety block 53 by connecting rod 52, and safety block 53 clamps guide rail to brake carriage, energy
Greatly improve the safety of elevator.
Above-described is only some embodiments of the present invention.For those of ordinary skill in the art, not
Under the premise of being detached from the invention design, various modifications and improvements can be made, these belong to protection model of the invention
It encloses.
