Description
Technical field
The utility model relates to unlocking apparatus, in particular to a kind of simplified elevator layer door Semi-automatic safety unlocking apparatus.
Background technique
Simplified elevator is to pass through steel wire using traction machine, hoist engine, electric block, hydraulic power unit etc. as driving device
The components such as rope, rack-and-pinion, chain or hydraulic cylinder drive container, along vertical or be less than with angle inclined vertically in hoistway
The hoisting machinery for being only used for delivery cargo of 15 ° of rigid guiding device operation.
It hoistway or is sheared by simplified elevator to prevent user and other staff from falling, simplified elevator is provided with layer door
Guarantee safety with cargo box door.Layer door is divided into cargo box door driving and manual two kinds of patterns.According to GB 28755-2012 simple lifting
Machine safety code regulation: layer door must be provided with mechanical chain and electrical interlocking device.
Currently, the door lock assembly of layer door generallys use a layer door lock locking, layer door lock shaping type is gravity+spring locking.
The device of unlocking generally has semi-automatic unlocking and two classes of unlocking manually there are many mode.It is unlocked manually using the side for pulling door lock
Formula is unlocked, semi-automatic to use the unlocking apparatus such as electromagnet, push rod, decelerating motor.
Electromagnet is unlocked because electromagnet thrust is smaller, and failure is usually easy to appear.Directly adopt the unlocking dress of decelerating motor
Set often involve great expense, volume is heavy, inconvenient for use.
A kind of common unlocking structure on existing market are as follows: push-and-pull motor passes through a pair of of feed screw nut the rotation of motor
Movement become moving along a straight line, using motor forward/backward rotation complete push pull maneuver, directly by unlocking hit bow push door lock pulley carry out
It unlocks.It is easily manufactured the advantage of this structure is structure is simple, but the problem of thus bringing also compare it is more.Due to layer door lock
Structure be designed as opening door lock latch hook upwards, and push-rod electric machine using Level Promoting door lock latch hook break off relations, therefore unlock when institute
It needs dynamics larger, burns out motor since latch hook is stuck under extreme case, and since motor thrust is larger, often lead to door lock
Stopper displacement, ensure layer door cannot effectively safely.Since push rod cannot effectively shift position onto, therefore motor rotation blockage electric current is very
Greatly, simplified elevator fault is caused when serious, influences to use safely.
Since conventional structure cannot limit the rotation of motor output shaft, therefore hits bow and usually rotated around motor reel, thus
Generate failure.
Utility model content
To be solved in the utility model is to overcome the deficiencies of the prior art and provide one kind to meet GB28755 " simple liter
Drop machine safety code ", and the semi-automatic unlocking apparatus of layer door of the simplified elevator of energy reliability service.
The above-mentioned technical purpose of the utility model has the technical scheme that a kind of simplified elevator
Semi-automatic layer door unlocking apparatus, including push-pull mechanism, regulating mechanism and rotating mechanism, the push-pull mechanism is for driving rotation
Mechanism rotation, the rotating mechanism include the swing arm for hitting elevator door lock hook, the swing arm and cargo box door machine bottom board
Hingedly.
After above-mentioned technical proposal, after reaching stop, when push-pull mechanism works, the pendulum in rotating mechanism is driven
Arm moves in a circle.Swing arm turns to shock layer door lock hook, to achieve the purpose that unlocking, being compared to push directly up makes
The displacement of layer door lock hook is obtained, this unlocking apparatus can prevent latch hook stuck and burn out motor.
The utility model is further arranged to: the push-pull mechanism includes push-and-pull motor, and the push-and-pull motor, which is connected with, to be pushed away
Bar, the push rod and swing arm are hinged.
After above-mentioned technical proposal, push-and-pull motor driven push rod sliding, so that push rod promotion is hinged therewith
Swing arm rotation, to achieve the purpose that unlocking.
The utility model is further arranged to: the regulating mechanism includes motor cabinet, the motor cabinet and container door machine bottom
Plate is fixedly connected, and motor rotary pin shaft is equipped on the motor cabinet, and the push-and-pull motor and motor rotary pin shaft are rotatablely connected.
After above-mentioned technical proposal, it is mounted on motor rotary pin shaft by the way that motor will be pushed and pulled, so that should
When unlocking apparatus is used for the elevator of different model, the angle of adjustable push-and-pull motor, so that push-and-pull motor can fit
For the elevator of different model, can also be adjusted when needing to adjust the angle of push-and-pull motor.
The utility model is further arranged to: the swing arm is fixedly connected with the door knife for being used to open elevator door lock.
The utility model is further arranged to: the door knife upper and lower ends end is provided with inclined-plane.
The utility model is further arranged to: the push-and-pull electrical power executes projecting motion, and push rod extends, described in drive
Circle swing is done in swing arm, and the door knife shock layer door lock hook being fixed in swing arm is allowed to unlock.
In conclusion the utility model has the following beneficial effects: being circle swing movement, layer door lock since door lock hits bow
Dress wheel stress be oblique upper thrust, and unconventional horizontal thrust reduces the generation of the locked probability of door lock.Due to door lock
Hit bow be circle swing move, hit bow movement be plane in circular motion, overcome routinely arrange hit bow position deflection
Defect, prevent the generation of unlocking failure.Compared with prior art, the utility model structure is simple, easy for installation, service life
Length, failure rate are low, meet elevator safety regulation and requirement.
