Specific embodiment
Below in conjunction with the accompanying drawings, specific embodiment of the invention is illustrated.
As shown in Figure 1 and Figure 2, a kind of overspeed protective device for staircase drives the output shaft of main frame 1 by being matched with
Limiter of speed limited block 4, limiter of speed support 6 are constituted, and limiter of speed limit is also set up between limiter of speed limited block 4 and limiter of speed support 6
Position block driving lever 5.Limiter of speed limited block 4 and the pin joint of drive gear 2.Main frame 1 is driven to export for cooperation in being provided with drive gear 2
First mounting hole 202 of axle, is also provided with a pair for coordinating centered on the center of circle of the first mounting hole 202, on drive gear 2
First location hole 201 of the one end of straight pin 3.Boss 402 is set in the side of limiter of speed limited block 4, boss 402 is triangle,
In this implementation clever, three draw-in grooves 401 are formed between the periphery of boss 402 and the outward flange of limiter of speed limited block 4.Draw-in groove 401
Groove width it is corresponding with the width of limiter of speed limited block driving lever 5.As shown in Fig. 2 being provided with the boss 402 of limiter of speed limited block 4
The second mounting hole 403 of the output shaft of main frame 1 is driven for coordinating, centered on the center of circle of the second mounting hole 403, in limiter of speed limit
Position block 4 is also provided with a pair the second location holes 404 for coordinating the other end of straight pin 3.
Limiter of speed limited block driving lever 5 is matched with one end of driving lever fixing axle 604, and the other end of driving lever fixing axle 604 runs through
Limiter of speed support 6.One end diameter that driving lever fixing axle 604 is provided with torsion spring draw-in groove 605 is straight less than the other end of driving lever fixing axle 604
Footpath.Driving lever fixing axle 604 is tapped by copper rod and is arranged on limiter of speed support 6.As shown in Fig. 2 in limiter of speed support 6 relative to
The side of limiter of speed limited block 4 also sets up bumping post 603, and tooth 601 is also set up in the end of limiter of speed support 6.
In the fixing axle mounting hole 501 for coordinating driving lever fixing axle 604 is provided with limiter of speed limited block driving lever 5, in limit
Mounting hole 502 is also provided with fast device limited block driving lever 5.In one end that driving lever fixing axle 604 and limiter of speed limited block driving lever 5 coordinate
Also it is provided with the torsion spring draw-in groove 605 for coordinating the one end of torsion spring 7, the other end and the clamping of bumping post 603 of torsion spring 7.Torsion spring 7 when mounted
Coordinate driving lever fixing axle 604 one end stretch into first it is in mounting hole 502 and corresponding with the position of fixing axle mounting hole 501, then
Limiter of speed limited block driving lever 5 with torsion spring 7 is enclosed within driving lever fixing axle 604 together, makes limiter of speed limited block driving lever 5 all the time
Abutted with bumping post 603 by the effect of torsion spring 7.Further extend outward to form flange 602 in the top of limiter of speed support 6, flange 602 is used
It is connected in the one end with extension spring (not shown), the other end of extension spring is connected with mainframe.
Specific work process of the invention is as follows：
As shown in Figure 1 and Figure 2, when staircase speed overrate, the output shaft faster rotational speed of main frame 1 is driven, so that
The faster rotational speed of drive gear 2 is driven, because drive gear 2 is connected by straight pin 3 with limiter of speed limited block 4, therefore limiter of speed
The rotating speed of limited block 4 also increases, and after the rotating speed of limiter of speed limited block 4 increases suddenly, limiter of speed limited block driving lever 5 is by centrifugation masterpiece
With that can be embedded in the draw-in groove 401 of limiter of speed limited block 4, main frame 1 is now driven to continue to run with, due to limiter of speed limited block driving lever
5 abut with the bumping post 603 of limiter of speed support 6, therefore drive limiter of speed support 6 to move downward by limiter of speed limited block driving lever 5, directly
Tooth 601 to limiter of speed support 6 is held tightly with staircase guide rail, and limiter of speed support 6 can trigger safety switch while alarm
(not shown), makes staircase speed decline and be driven by controller out of service.Subsequently need staircase edge
The opposite direction jiggering of downslide, while pulling down host housing, limiter of speed limited block driving lever 5 is resetted, and it is separated with draw-in groove 401,
It is capable of achieving the normal operation of staircase.
Above description is explanation of the invention, is not the restriction to inventing, and limited range of the present invention is referring to right
It is required that, in the case of without prejudice to basic structure of the invention, the present invention can make any type of modification.
