Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described.
As shown in Figure 1 and Figure 2, a kind of overspeed protection device for staircase forms by being matched with the velocity limiter limiting stopper 4, the velocity limiter support 6 that drive main frame 1 output shaft, also arranges velocity limiter limiting stopper driving lever 5 between velocity limiter limiting stopper 4 and velocity limiter support 6.Velocity limiter limiting stopper 4 and driven wheel 2 pin joint.Having on driven wheel 2 for coordinating the first mounting hole 202 driving main frame 1 output shaft, centered by the center of circle of the first mounting hole 202, on driven wheel 2, also having a pair for coordinating first knock hole 201 of straight pin 3 one end.Arrange boss 402 in the side of velocity limiter limiting stopper 4, boss 402 is triangle, in this enforcement clever, forms three draw-in grooves 401 between the periphery of boss 402 and the outward flange of velocity limiter limiting stopper 4.The groove width of draw-in groove 401 is corresponding with the width of velocity limiter limiting stopper driving lever 5.As shown in Figure 2, have for coordinating the second mounting hole 403 driving main frame 1 output shaft on the boss 402 of velocity limiter limiting stopper 4, centered by the center of circle of the second mounting hole 403, also have a pair for coordinating the second knock hole 404 of straight pin 3 other end at velocity limiter limiting stopper 4.
Velocity limiter limiting stopper driving lever 5 is matched with one end of driving lever anchor shaft 604, and the other end of driving lever anchor shaft 604 runs through velocity limiter support 6.One end diameter that driving lever anchor shaft 604 has a torsion spring draw-in groove 605 is less than the other end diameter of driving lever anchor shaft 604.Driving lever anchor shaft 604 is knocked by copper rod and is arranged on velocity limiter support 6.As shown in Figure 2, in velocity limiter support 6, bumping post 603 is also set relative to the side of velocity limiter limiting stopper 4, tooth 601 is also set in the end of velocity limiter support 6.
On velocity limiter limiting stopper driving lever 5, having the anchor shaft mounting hole 501 for coordinating driving lever anchor shaft 604, velocity limiter limiting stopper driving lever 5 also having waist shaped hole 502.The torsion spring draw-in groove 605 for coordinating torsion spring 7 one end is also had, the other end of torsion spring 7 and bumping post 603 clamping in one end that driving lever anchor shaft 604 coordinates with velocity limiter limiting stopper driving lever 5.Torsion spring 7 coordinates one end of driving lever anchor shaft 604 first to stretch in waist shaped hole 502 and corresponding with anchor shaft mounting hole 501 position when mounted, then the velocity limiter limiting stopper driving lever 5 with torsion spring 7 is enclosed within driving lever anchor shaft 604 together, velocity limiter limiting stopper driving lever 5 is abutted with bumping post 603 by the effect of torsion spring 7 all the time.Also stretch out in the top of velocity limiter support 6 and form flange 602, flange 602 is for being connected with one end of extension spring (not shown), and the other end of extension spring is connected with mainframe.
Specific works process of the present utility model is as follows:
As Fig. 1, shown in Fig. 2, when staircase speed overrate, drive main frame 1 output shaft faster rotational speed, thus drive driven wheel 2 faster rotational speed, because driven wheel 2 is connected with velocity limiter limiting stopper 4 by straight pin 3, therefore the rotating speed of velocity limiter limiting stopper 4 also increases, after velocity limiter limiting stopper 4 rotating speed increases suddenly, velocity limiter limiting stopper driving lever 5 can be embedded in the draw-in groove 401 of velocity limiter limiting stopper 4 by centrifugal action, main frame 1 is now driven to continue to run, because velocity limiter limiting stopper driving lever 5 abuts with the bumping post 603 of velocity limiter support 6, therefore velocity limiter support 6 is driven to move downward by velocity limiter limiting stopper driving lever 5, until the tooth 601 of velocity limiter support 6 is held tightly with staircase guide rail, velocity limiter support 6 meeting triggering secure switch (not shown) while warning, staircase speed is made to decline and be driven by controller out of service.Follow-up needs, by the reversing sense jiggering of staircase along downslide, pulls down host housing simultaneously, is resetted by velocity limiter limiting stopper driving lever 5, make it be separated with draw-in groove 401, can realize the normal operation of staircase.
More than describing is to explanation of the present utility model, and be not the restriction to utility model, the utility model limited range is see claim, and when without prejudice to basic structure of the present utility model, the utility model can do any type of amendment.
