Wirerope is fixed on bending plate, is easily installed and adjusts and fixed effect is stronger.
Preferably, installing handrail on the foot pedal；The handrail can be rotated around foot pedal；It is set on the foot pedal
There is a groove for storing handrail.It is stepped on to personnel and provides safety guarantee when foot pedal rises and convenient for the receipts of handrail
It receives.
Preferably, infrared inductor is installed in the foot pedal bottom.For an inspection to foot pedal bottom environment
It looks into, prevents from damaging people and goods, play the role of safeguard protection.
Preferably, installing a gravity sensor and a gravity sensing switch above the foot pedal；The gravity
Inductor is by gravity sensing switch control.For incuding, whether someone stands on the footrests when gravity sensor is powered.
Preferably, the gravity sensor is used to control motor operating by controller.It can save for controlling electricity
The button switch of machine operating, the simpler convenience of control mode for operating motor.
The utility model has the following beneficial effects: the personnel in carriage can pass through carriage when elevator encounters failure
Interior safety device quickly opens escape scuttle and carries out self rescue, saves and waits rescue period in carriage and alleviate
Self rescue difficulty.Using two motor drivens, keep the lifting of foot pedal apparatus more steady.

Specific embodiment
A kind of safety device in the present embodiment, in lift car, it is characterised in that: including two sets of motor drivers and
Foot pedal apparatus；The motor driver draws foot pedal apparatus by wirerope 1；The motor driver is by controlling
Device 2 controls；The motor driver is placed in carriage and is separated by partition 3；Rectangular channel 4 there are two being set on the partition 3.
The installation of this implementation: two motors 5 are mounted on sedan-chair wall 20 by rack 19 respectively, and the output end of motor 5 passes through
Shaft coupling 21 is connected with one end of axis 6, and the other end of axis 6 is connected by bearing 22 with column 8, and pulley 7 is mounted on axis 6, and
And pulley 7 is linked together by wirerope 1.
Foot pedal apparatus includes 12, eight pieces of foot pedal 9, two block baffles 10, back plate 11, bottom plate bending plates 13；In back plate 11
Eight slotted holes utilize the position of the adjustable bending plate 13 of slotted hole for installing bending plate 13.Then wirerope 1 passes through two
Between block bending plate 13, bending plate 13 is clamped using shank of bolt 23 and nut 24, so that wirerope 1 is pressed from both sides using bending plate 13
Tightly, it is fixed on entire foot pedal apparatus on wirerope 1.
Then entire motor driver is separated using partition 3, two rectangular channels 4 is opened on partition 3 and facilitate foot pedal apparatus
It is connected with wirerope 1, while does not allow entire motor driver exposed in carriage again.
5 rotation position of motor is adjusted finally by controller 2, is when foot pedal 9 rises to apart from 1 meter of security window
Upper limit；It is lower limit when foot pedal 9 is apart from 0.3 meter of car floor.
The working method of safety device in this lift car: when elevator encounters failure, trapped person is first
The rotation of handrail 14 being accommodated in 9 groove 15 of foot pedal as 9 upright position of foot pedal, gravity sensing switch is then opened
18, it allows gravity sensor 17 to be powered, and then stands on foot pedal 9, when the gravity sensor 17 on foot pedal 9 senses gravity
When, controller 2 is sent a signal to, controller 2 drives two motors 5 to rotate in the same direction with frequency therewith, drives foot pedal apparatus to rise, quilt
The oppressive hand steered handrail 14 of member, until motor 5 stops operating when foot pedal apparatus rises to upper limit, trapped person opens security window
Carry out self rescue；After personnel flee from carriage, when the gravity sensor 17 on foot pedal 9 is incuded less than gravity, send out again
Signal declines foot pedal apparatus to controller 2 out, until motor 5 stops operating, then next quilt when dropping to lower limit
Oppressive member continues above-mentioned movement and carries out self rescue.After troubleshooting, elevator in the condition of normal use, closes gravity
Inductive switch 18 allows gravity sensor 17 to power off, and handrail 14 is accommodated in the groove 15 of foot pedal 9.
