Embodiment
Below in conjunction with accompanying drawing, 1 to 3 couple of present invention does detailed introduction:The present invention includes elevator 1 and positioned at elevator
Car 2 in 1, the bottom of described elevator 1 are provided with the slow descending device that falls, and the slow descending device that falls includes being used to control electricity
The starter 3 of road Push And Release, coil 4, the powering shelf 5 that magnetic field can be produced after being powered;Described coil 4 is located at elevator and normally made
Below the horizontal plane of the bottom of car 2, and in screw arrangement on vertical direction and the bottom surrounding in elevator 1;
Described coil 4 is connected by starter 3 with powering shelf 5, and is that coil 4 provides required power supply, institute by the powering shelf 5
The powering shelf 5 stated is arranged on the outside borehole wall of elevator 1;When elevator normal use, the slow descending device that entirely falls is in and treated
Life state;When the situation of falling, the triggering starter 3 of car 2, and car 2 sectioned coil 4 under gravity occurs in car 2
Produced magnetic induction line causes car slows down to delay drop;The slow descending device that falls being provided with elevator 1 is mainly used in solving traction
Formula elevator in use, because contingency causes lift car from falling from high altitude, causes great personnel to injure or wealth
The problem of production loss.
The described internal diameter of coil 4 by spiral way arrangement is more than the external diameter of car 2 so that car 2 can shuttle vertically in
In coil 4;When situation is occurring falling in car 2, the car 2 is located on the inside of the coil 4 of spiral way arrangement, in coil 4
Portion can produce powerful magnetic field, make when through this section of region significantly to be slowed down by car made of metal material, finally
Steadily land.
The described height of coil 4 is 1.2-1.8 times of the height of car 2, and the purpose so designed is:Car 2 is set to exist
Coil 4 obtains good buffering effect, is unlikely to the bottom of the bottom of car 2 contact elevator 1.
Described starter 3 includes light emitters 31, light collector 32, the light emitters 31, light collection
Device 32 is arranged on the outside borehole wall of elevator 1, and the daylighting source 33 that light emitters 31, light collector 32 are each provided with
The through hole opened up through the borehole wall of elevator 1, and on the inner side borehole wall of elevator 1;
Described light emitters 31, light collector 32 are located at the over top of coil 4 arranged by spiral way, favorably
In sensing that car 2 drops in advance, and electric signal is exported to powering shelf 5 by light collector 32 in time, coil 4 is produced magnetic
.
Described light emitters 31 are arranged on the side of the borehole wall of elevator 1, and light collector 32 is arranged on the well of elevator 1
The opposite side of wall, and the position on the elevator 1 at place will be distributed in two avris of car 2 between the two, and two avris is not
Car door can be set.
Described light emitters 31, the daylighting source 33 of light collector 32 are in corresponding distribution, so that light is sent out
It is more accurate that light is gathered between emitter 31 and light collector 32.
The electric signal that described light collector 32 is exported communicates with powering shelf 5;Elevator is in normal use, light hair
Have no occluder between emitter 31 and the daylighting source 33 of light collector 32, the electric signal control that now light collector 32 exports supply
The electric circuit of cabinet 5 is simultaneously off;When the situation of falling occurs in car 2, fall to light emitters 31 and light collector 32
Daylighting source 33 between when, the light in daylighting source 33 can be stopped, now the output signal of light collector 32 supplies powering shelf 5
Electricity, make to produce magnetic field in coil 4.
The present invention operation principle be:The installation site of coil 4 is below the horizontal line of elevator normal use, outside and powering shelf
5 are connected, and powering shelf 5 is by light collector 32 come the break-make of control circuit, and during normal use, light emitters 31 gather with light
Have no occluder between device 32, the electric signal control circuit of powering shelf 5 that now light collector 32 exports are off, entirely
Device is standby, when the situation of falling occurs in lift car, falls between light emitters 31 and light collector 32
When, light can be stopped, now the output signal of light collector 32 makes powering shelf 5 power, by being produced in the coil 4 of screw arrangement
Powerful magnetic field, lift car cutting magnetic induction line under gravity, according to the action condition of Lenz's law, now elevator car
The speed in railway carriage or compartment drastically declines, and reaches the purpose for slow drop of slowing down.
It is understood that it will be understood by those skilled in the art that technical scheme and inventive concept are subject to
The protection domain of appended claims of the invention should all be belonged to replacement or change.
