It is arranged on wall 13, and the wall 13 is hoistway, is the hoistway for placing elevator.Sensing device 11 and anti-fall mechanism 12 be
Each layer of elevator exit is designed with.It can guarantee that elevator will not directly be fallen in this way, but each layer all can be corresponding
Elevator is blocked, the accident rate of elevator is reduced to minimum.
Carriage 10 is equipped with chamber door 14 and upper piece 15, upper piece 15 two sides for being arranged in carriage 10, is in the two sides of chamber door 14.
Upper piece 14 be for riding over anti-fall mechanism 12, so that carriage 10 will not directly fall.
Sensing device 11 is arranged on the wall 13 of 14 opposite of chamber door, and guide rail 16 is additionally provided in carriage 10, and guide rail 16 is
Directly it is mounted on the rear end of carriage 10.Guide rail 16 is for positioning sensing device 11, and the top and bottom of guide rail 16 are to sedan-chair
The direction in compartment 10 is invaginated, and the centre of guide rail 16 is parallel with the exterior face of carriage 10, is in circular arc mistake among guide rail upper end and guide rail
It crosses, is in arc transition among guide rail lower end and guide rail.At runtime, the front end of sensing device 11 is to touch guide rail 16 to elevator
's.
Anti-fall mechanism 12 be arranged in upper piece 15 lower end, anti-fall mechanism 12 is that have setting, anti-fall mechanism 12 in each layer
In include cylinder 17 and lower piece 18, cylinder 17 be equipped with cylinder rod 171, lower piece 18 is mounted on cylinder rod 171, sets on wall 13
There are cavity slot 19 and cylinder groove 20, cavity 22 is mounted in cavity slot 19, and cylinder 17 is mounted in cylinder groove 20.Upper piece set on 15
There is positioning groove 151, lower piece 18 is equipped with locating convex block 181, and locating convex block 181 matched can be mounted on positioning groove 151
In.When carriage 10 is fallen, 10 two sides of carriage upper piece 15 can fall on lower piece 18, upper piece positioning groove 151 on 15 can be straight
What is connect corresponds on the locating convex block 181 on lower piece 18, can prevent carriage 10 from misplacing.
It include briquetting 21, cavity 22, idler wheel 23 and spring 24 in sensing device 11, idler wheel 23 is mounted on by rotary shaft 25
The front end of briquetting 21, idler wheel 23 can be rotated by rotary shaft 25 on briquetting 21, and elevator is running to 11 front end of sensing device
When, idler wheel 23 is just directly fallen on track 16.It is equipped with cambered surface lug boss 161 and recessed portion 162, recessed portion on track 16
162 are equipped with cambered surface recessed portion 231 and lug boss 232 in the two sides of cambered surface lug boss 161, idler wheel 23, and cambered surface recessed portion 231 is right
That answers is placed on cambered surface lug boss 161, and lug boss 232 is corresponding to be placed in recessed portion 162.Pass through guide rail 16 and rolling in this way
The cooperation of wheel 23, enables sensing device 11 accurately to fall on track 16, will not deviate.Briquetting 21 is mounted on cavity 22
In, briquetting 21 can be movable in cavity 22.The rear end of briquetting 21 is equipped with blocking portion 211, and blocking portion 211 leads in cavity 22
Blocking portion 211 is crossed, briquetting 21 will not be deviate from when movable in cavity 22 from cavity 22.Spring 24 is mounted on blocking portion 211,
The centre of spring 24 is equipped with positioning column 26, and positioning column 26 is mounted on blocking portion 211.And after spring 24 is mounted on briquetting 21
End, spring 24 are arranged in cavity 22.
