Description

A kind of screw type elevator mechanical emergency deliverance apparatus
Technical field
The present invention relates to screw type elevator emergency relief field, specifically a kind of screw type elevator mechanical emergency rescue Device.
Background technique
The common structure of screw type elevator is to install driving motor and nut body in lift car bottom, and screw rod setting exists In elevator shaft, driving motor driving nut rotation, nut drive carriage to move down along screw rod when needing carriage to go up and down It is dynamic.
But existing emergency rescue device for elevator can not be applied to screw type elevator emergency relief substantially, and without single The rescue mode of purely mechanic device, when the electric part of screw type elevator can not work, rescue is very difficult.
A kind of safe and reliable mechanical life device is now needed, while also needing to guarantee have independence when artificial fatigue Power supply be powered, to cooperate manual operation.
Summary of the invention
The present invention is exactly to provide a kind of screw type elevator mechanical emergency in order to solve deficiencies of the prior art and rescue Shaking apparatus, when screw type elevator main circuit power off suddenly people be trapped in need leveling in elevator when, latching relay at this time It driving internal contracting brake mechanism to unclamp in elevator supply circuit power loss, manually shakes rocking bar, rocking bar drives worm screw to rotate by motor shaft, And then worm gear rotation is driven, worm gear drives the screw rod rotation of bolt and nut system by connecting rod, due to main circuit power loss, under carriage The driving motor in portion and nut stopping movement can reach the purpose of leveling so screw rod rotation drive carriage moves up and down.
When rescue personnel is tired or needs to drive carriage to move up and down at faster speed, manual switch is opened So that battery is connected to motor, the movement of motor rotate driving worm-gear speed reducer, and then drive screw turns, reaches more rapidly Driving carriage move up and down.
The technical scheme adopted by the invention to solve the technical problem is that:
A kind of screw type elevator mechanical emergency deliverance apparatus, the bolt and nut system including screw type elevator, further includes snail Worm and gear speed reducer, motor, battery, the turbine of the screw rod connection worm-gear speed reducer of the bolt and nut system, institute The worm screw for the motor driven connection worm-gear speed reducer stated, the battery connect motor.
A kind of screw type elevator mechanical emergency deliverance apparatus further includes the frame base of elevator, pacifies on the frame base Speed reducer mounting base is filled, the worm-gear speed reducer is mounted on speed reducer mounting base, the spiral shell of the bolt and nut system Bar is connected on the turbine of worm-gear speed reducer by connecting rod
