The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the utility model is described in further detail.
As depicted in figs. 1 and 2, anti-cutting mechanism in the utility model is made by waterproofing materials, the present embodiment is take stainless steel material as example, and it includes stainless steel motion bar 1, two slide bars 2, stainless steel fixed bar 3, bearing 4, balancing weight 5, annular seal space 6, tilt switch 7 and elastic fabrics 8.Wherein slide bar 2 quantity can be more than two, set according to specific circumstances.
The lower end of two slide bars 2 is fixedly connected with stainless steel motion bar 1, and this connection can be welding, can be also that connector connects, and makes on the parallel the same side that is fixed on stainless steel motion bar 1 of two slide bars 2.Stainless steel fixed bar 3 is provided with two through holes 10 in the position of corresponding slide bar 2, as shown in Figure 3 and Figure 4, make two slide bars 2 respectively through the through hole 10 of stainless steel fixed bar 3 can be in the interior slip of through hole 10, the utility model, in order to make the smooth slip of slide bar 2, is provided with non-metallic bushings 14 in through hole 10.In the upper end of every slide bar 2, be furnished with some balancing weights 5, be that some balancing weights 5 are located on slide bar 2, and sealed fixing by nut 13, the quantity of balancing weight 5 and weight can be according to field condition adjustment simultaneously, upper end at slide bar 2 is provided with acorn nut 15 between stainless steel fixed bar 3 and balancing weight 5, and slide bar 2 is positioned.The bottom of annular seal space 6 is directly withstood on the top of slide bar 2, and can, along annular seal space 6 basal slidings, be provided with the chute (not shown) of sliding for slide bar 2 tops at the outer bottom of annular seal space 6.
Annular seal space 6 includes cavity and end cap 9, between cavity and end cap 9 by rubber gasket 11, in the centre of end cap 9, be provided with the hole (not shown) of current supply cable 12 hermetically passings, tilt switch 7 is put in fixing being placed with by jelly 18 in cavity, cable 12 through hole is connected with tilt switch 7, as shown in Figure 5.One end of annular seal space 6 and bearing 4 are articulated and connected, and on bearing 4, are provided with the pin 15 that can prevent that annular seal space 6 rotation amplitudes are excessive; Bearing 4 is fixed on stainless steel fixed bar 3; Side between stainless steel motion bar 1 and stainless steel fixed bar 3 is furnished with elastic fabric 8, utilizes elastic fabric 8 to be coated on stainless steel motion bar 1 and stainless steel fixed bar 3, reduces between stainless steel motion bar 1 and stainless steel fixed bar 3 and stage and rubs.
Stainless steel motion bar 1, stainless steel fixed bar 3 in the above-described embodiments also can bend to circular-arc use, to coordinate the stage of multiple moulding, thereby can make anti-cutting mechanism in the utility model according to the feature of stage, be directly arranged in the side of elevator stage, as shown in Figure 6, shown in A-A, locate in the drawings an anti-cutting mechanism to be set at the side of water-stage, at the side that is in adjacent stage shown in B-B, respectively establish an anti-cutting mechanism.Stainless steel motion bar 1, stainless steel fixed bar 3 also can be made of other waterproofing materialss simultaneously.
In the utility model, the concrete anti-shear history of the anti-cutting mechanism of elevating stage is as follows: elevator stage is when lifting, because there is relative motion in the edge between the edge between elevating stage or elevating stage and fixed station (also claiming fixing stage), the edge line of polylith elevating stage as shown in Figure 6, when the object on table top exceeds elevating stage edge as performer's pin, scenery, easily by table top, sheared, as shown in Figure 7.For preventing the generation of the situation of shearing, in elevating stage surrounding and the fixing stage continuous edge adjacent with elevating stage, arrange the anti-cutting mechanism in the utility model, as shown in Figure 8.When exceeding elevating stage edge as performer's pin, scenery, during elevating stage motion, will touch the motion bar 1 of anti-cutting mechanism, motion bar 1 moves upward, and by slide bar 2, further drives the tilt switch 7 in annular seal space 6 to move.Tilt switch 7 is connected with the driving control system of elevating stage, when control system monitors tilt switch 7 and moves, stops immediately the motion of elevating stage, thereby avoids the generation of shearing accident, thereby greatly improved the reliability of the anti-shearing of water-stage.
