Description
Technical field
The present invention relates to elevator safety technical field, more particularly to a kind of elevator limiting safe device.
Background technology
Elevator is realization when lift car reaches predetermined floor during actual use
The stable stop of designated floor is reached to elevator, lift car subtracts first when Jie Jin predetermined floor
Then speed stop completely, and the whole process of car is completed by a set of trigger mechanism, trigger mechanism bag
The trigger board being arranged on car is included, the sensing that car constitutes vertical direction with track is oriented to and coordinates,
Trigger switch is provided with the track for closing on response floor, the trigger switch is used for opening elevator
The deceleration device of setting, the deceleration device is used for the speed that moves up and down of controlled motor car, utilizes
Above-mentioned a set of trigger mechanism is capable of achieving the stable stop of above-mentioned car, it is to avoid elevator jerk and occur
Shaking phenomenon.But when elevator rises to elevator highest position, or drop to elevator most
When at lower position, lift car occurs the dangerous phenomenon rushed to summit or squat over a pit to relieve oneself.
The content of the invention
It is an object of the invention to：Offer one kind can eliminate lift car to be occurred rushing to summit or squats over a pit to relieve oneself
The elevator limiting safe device of phenomenon.
For achieving the above object, the technical solution used in the present invention is：A kind of elevator limiting safe dress
Put, close on elevator install well minimum point and peak position at be respectively arranged with trigger board, it is described
Trigger board is connected with guide rail, and trigger board may move up and down positioned at vertical direction, and lift car is located at electricity
Stair shaft is moved up and down and constitutes against or separate cooperation, the other end of trigger board with one end of trigger board
With limit switch with the deceleration list for merging driving stage limit switch open and closing, limit switch and elevator
Unit's connection, limit switch opens and closes correspondence deceleration unit and starts and closing motion.
Compared with prior art, the technique effect of present invention presence is：Using being arranged on elevator
Trigger board is respectively provided with least significant end and peak position, when elevator is to moving up and down and rise to most
When at high point or lowest point, car is constituted against with trigger board or separates cooperation, so that
Trigger board coordinates with limit switch, and trigger switch is turned on and off, and then causes to slow down
Unit starting or closing, when elevator is risen at peak or lowest point so that slow down single
Unit starts, and so as to realize the deceleration of lift car, and then avoids rushing to summit or squatting for lift car appearance
The dangerous phenomenon in hole.
Description of the drawings
Fig. 1 is principle schematic when limiting safe device is assembled with elevator；
Fig. 2 is the structural representation of limiting safe device.
Specific embodiment
With reference to Fig. 1 and Fig. 2, the present invention is further described：
A kind of elevator limiting safe device, closes on minimum point and peak position that elevator installs well
The place of putting is respectively arranged with trigger board 10, and the trigger board 10 is connected with guide rail 20, trigger board 10
May move up and down positioned at vertical direction, lift car 30 move up and down positioned at elevator and with triggering
One end of plate 10 constitutes against or separates and coordinates, the other end and the limit switch 40 of trigger board 10
Open and close with driving stage limit switch 40 is merged, limit switch 40 connects with the deceleration unit of elevator
Connect, limit switch 40 opens and closes correspondence deceleration unit and starts and closing motion.Using setting
Trigger board 10 is respectively provided with the least significant end of elevator and peak position, when lift car 30
When moving up and down and rising at peak or lowest point, car 30 and the structure of trigger board 10
Into against or separate and coordinate so that trigger board 10 coordinates with limit switch 40, and so that
Trigger switch 40 is turned on and off, and then deceleration unit is started or is closed, and works as lift car
30 when rising at peak or lowest point so that deceleration unit starts, so as to realize elevator
The deceleration of car 30, and then avoid the dangerous phenomenon rushed to summit or squat over a pit to relieve oneself of the appearance of lift car 30.
Used as the preferred version of the present invention, the trigger board 10 is overall to be presented the vertical batten of plate face
Shape structure, the plate length direction of trigger board 10 vertically, the end of car 30 and one end structure of trigger board 10
Into against or separate coordinate when, correspondence trigger board 10 move up and down and cause the upper end of trigger board 10 with
Limit switch 40 is constituted against unlatching and separates closing cooperation.Using the trigger board of bar platy structure
10, the material of the trigger board 10 at this can select the metal material of elasticity, lift car 30 with
Trigger board 10 can weaken the impact injury to trigger board 10 against the process collided, and can
The reset of quick shape.
Further, the two ends of the trigger board 10 are arranged to flap-like structure, to avoid elevator
The phenomenon that more than 30 trigger board of car 10 contacts the process collided and causes the bending of trigger board 10 failure,
Preferably, the angle between the flap-like structure and trigger board 10 at the two ends is 120 ° to 150 °.
It is optimal to triggering to reach for convenience of the debugging to trigger board 10 and the position of limit quick closing valve 40
The unlatching of switch 40 and closure effect, constitute vertically side between the trigger board 10 and guide rail 20
To and horizontal direction adjustable cooperation.
Specifically, trigger board 10 is connected with one end of first support 50, the plate face of trigger board 10
Offer bar hole 11 and hole length direction is vertical, pass through between trigger board 10 and first support 50
The connector 60 arranged in bar hole 11 is fastenedly connected, one end of the first support 50 and the
The one end of two support 70 connects, and the plate face of first support 50 offers the first bar hole 51 and hole is long
Direction level, is fastenedly connected, second between trigger board 10 and first support 50 by fastening bolt
Support 70 is connected with guide rail 20.
The connector 60 is made up of elastic rubber material, and connector 60 is shaft-like in bolt, connection
Part 60 is through bar hole 11 and end is plugged in the circular hole in first support 50.Using the bullet
Property connector 60 made by elastomeric material is to realize trigger board 10 same with what first support 50 was connected
When, and the effect of damping can also be played, when car 30 and trigger board 10 end against and rush
During hitting so that during trigger board 10 is moved upwardly or downwardly, trigger board 10 is caused
Connector 60 produces certain elastic bending, enable then trigger board 10 occur upwards or
Downward slight movement, and then the unlatching of limit switch 40 is triggered, when car 30 and trigger board 10
During separation, the elastic reset of connector 60, and then trigger board 10 is separated with limit switch 40.
Certainly, it is to realize effectively connection to trigger board 10, with reference to shown in Fig. 2, described the
One support 50 and second support 70 be located at vertical direction arranged for interval two groups or more.
