Signal input part, a signal projector can be set in elevator top plate, transmitter is put by connecting line 2 to controller 1
Signal is penetrated, once controller 1 does not receive the signal, then illustrates that elevator falls, such decision procedure both simply has can
Lean on, and can make a response the very first time.I.e. used during elevator falling when, speed is fast when speed is than normal work, can be that connecting line 2 is produced
Raw huge pulling force makes it break；Controller 1 triggers safety self-saving measure and sends alarm signal at once after breaking.
The lower section of elevator layer per floor is provided with a release mechanism, and release mechanism is by being symmetricly set on elevator inwall 4
Baffle plate assembly constitute, as shown in figure 3, baffle plate assembly include being embedded in the damping spring 7 of elevator inwall 4, level vertically it is embedding
Enter the rotating shaft supported in elevator inwall 4 by damping spring 7, the baffle plate being fixed in rotating shaft, rotating shaft two ends are fixed on shaft seat
On, shaft seat can put square structure, and it is embedded in the two ends of elevator inwall 4, and it can glide along on elevator inwall 4
It is dynamic, there is the position-limit mechanism that limitation axis of rotation angle is no more than 90 degree, then master shield 5 is along rotating shaft between rotating shaft and shaft seat
It is to turn to upset on vertical to be horizontal to rotate interval.
The damping spring 7 of support rotating shaft can set multigroup, uniformly be fixed on below rotating shaft, and it, which has, offsets elevator tenesmus
The cushioning effect of power, fixed rotating shaft and damping spring 7 for convenience, master shield 5 is fixed in rotating shaft by many connecting rods, electricity
The inside of stair shaft inwall 4 is provided with the vertical chute slided up and down for connecting rod, then can be reliable embedding by rotating shaft and damping spring 7
Enter in elevator inwall 4.
When turning on the master shield 5 is vertical, provided with propelling spring 8, and this between elevator inwall 4 and master shield 5
When propel spring 8 and compressed by master shield 5, elevator inwall 4 compresses the electric locking for propelling spring 8 provided with locking master shield 5
Mechanism, once electric locking mechanism discharges, then master shield 5 is ejected at once, improves the responsiveness of system, electric locking mechanism bag
The postive stop baffle that motor and limitation master shield 5 are launched is included, the motor is fixed on elevator inwall 4, and the postive stop baffle is fixed
In the rotating shaft of motor, the electric locking mechanism of the output drive signal of controller 1 to each release mechanism, i.e. output control signal
To motor.
Stand-by power supply is not set additionally in lift car 3, and stand-by power supply can not provide electricity to elevator again in main power source
When source is supported, provide power supply for other devices and help, such as：If elevator is powered off, lamp will extinguish, now stand-by power supply
Startup can make in elevator, not dimmed, will not also to make one to produce fear etc..
To ensure the reliability of the support tenesmus elevator of master shield 5, the elevator at the two ends of master shield 5 and the top of master shield 5
Safe drag-line is provided between well inwall 4.Provided with many support bars between each master shield 5 and corresponding vertical chute, every support
Bar top is hinged on the bottom surface of master shield 5, and bottom is embedded in vertical chute, i.e., constitute three by support bar in the bottom of master shield 5
Angular lower support structure, by the triangle pull-up support force of the drag-line on top, so that it is guaranteed that master shield 5 is difficult stress
It is excessive and under turn over, lose stop tenesmus lift car 3 function.
Provided with secondary baffle plate 6 in master shield 5, the outer end of master shield 5 is provided with opening, and secondary one end of baffle plate 6 is fixed on the bottom of master shield 5
