Specific embodiment
In the present embodiment, a kind of safe elevator lift-cabin includes furred ceiling, sedan-chair wall 3, fluid pressure drive device and lifting platform 15.It is described
Furred ceiling includes fixed ceilings plate 1 and mobile ceiling board 2, and the two sides of fixed ceilings plate 1 are respectively equipped with groove 4, mobile ceiling board 2
Two sides are equipped with idler wheel 5；The piston rod 61 of hydraulic cylinder 6 and mobile ceiling board 2 are linked together with bolt screw rod, pass through hydraulic drive
Dynamic device makes mobile ceiling board 2 mobile.
The lifting platform 15 includes motor 11, lead screw 12, screw shell 13 and foot pedal 14, drives lead screw by motor 11
12 rotations, then drive screw shell 13 to rise or fall by lead screw 12, to drive rising or falling for foot pedal 14 indirectly.
The installation of this implementation: fixed ceilings plate 1 is directly vertically fixed on sedan-chair wall 3 using bolt nut, mobile ceiling board 2
It is inside contained in the cavity of fixed ceilings plate 1, the idler wheel 5 of mobile 2 two sides of ceiling board is allowed to be placed in the recessed of 1 two sides of fixed ceilings plate just
In slot 4.Pedestal 62, fuel tank 7 and the controller 8 of hydraulic cylinder 6 are fixed on sedan-chair wall 3 with bolt nut, screw shell 13 and foot-operated
Plate 14 welds together, and lifting platform 15 is in lift car.
The groove 4 of fixed ceilings plate 1 is built-in, and there are four limit switches 9, for limiting the moving range of mobile ceiling board 2.
There are two range sensors 90 for dress on the lead screw 12 of lifting platform 15, for detecting upper and lower two limit positions when foot pedal 14 is gone up and down
It sets.
The method of operation of this safe elevator lift-cabin are as follows: when elevator encounters failure, the people in carriage presses control panel
10 furred ceiling opens button 101, makes rod chamber oil inlet of the fuel tank 5 to hydraulic cylinder 6 by controller 8, hydraulic oil pushes piston 60
Shrink piston rod 61, the direction for driving mobile ceiling board 2 toward close hydraulic cylinder 6 is mobile, when idler wheel 5 encounters the limit in groove 4
When bit switch 9, piston rod 61 stops shrinking, and mobile ceiling board 2 stops movement, and furred ceiling is in the open state.
Then trapped person steps down on the foot pedal 14 of lifting platform 15, presses the lifting platform rising button of control panel 10
104, the motor 11 of lifting platform 15 starts, and drives lead screw 12 to rotate, then driven on screw shell 13 and foot pedal 14 by lead screw 12
It rises, when the range sensor 90 of 12 top of lead screw detects that motor 11 stops fortune when reaching setting value at a distance from foot pedal 14
Dynamic, trapped person escapes from open furred ceiling.As the more than people of trapped person, next bit trapped person presses control
The lifting platform declines button 103 of panel 10 first allows the foot pedal of lifting platform 15 to decline, and then repeats the dynamic of a captive
Make, continues to escape.
When elevator debugging continues to use, the furred ceiling close button 100 of control panel 10 is pressed, controller 8 is passed through
Make rodless cavity oil inlet of the fuel tank 5 to hydraulic cylinder 6, hydraulic oil pushes piston 60 to extend piston rod 61, drives mobile ceiling board 2 past
Direction far from hydraulic cylinder 6 is mobile, and when idler wheel 5 encounters the limit switch 9 in groove 4, piston rod 61 stops extending, and movement is hung
Top plate 2 stops movement, and furred ceiling is in close state.
When furred ceiling opens or closes, personnel in elevator can by the furred ceiling stop button 102 of control panel 10,
Mobile ceiling board 2 is allowed to stop movement at any time；In personnel of the foot pedal 14 when rising or falling, in elevator of lifting platform 15
By the lifting platform stop button 105 of control panel 10 foot pedal 14 can be stopped at any time.
