Accompanying drawing explanation
Fig. 1 is the position signalling flip flop equipment of a kind of sealing provided by the invention view when not triggering;
View when Fig. 2 is the position signalling flip flop equipment triggering of a kind of sealing provided by the invention.
Embodiment
Below in conjunction with the drawings and specific embodiments, the invention will be further described.
As depicted in figs. 1 and 2, the position signalling flip flop equipment of a kind of sealing provided by the present invention, the flip flop equipment comprising pedestal 12, be located at the proximity switch 1 on pedestal 12 and match with proximity switch 1; Flip flop equipment comprises axle 10 and is sleeved on signal mask 3 and the baffle plate supporting seat 4 on axle 10 top, and the bottom of axle 10 is stretched out and through the hole be located on pedestal 10 in the sleeve 11 be located on pedestal 10; Axle 10 has first shaft shoulder, second shaft shoulder from top to bottom, and baffle plate supporting seat 4 to be located on axle 10 on first shaft shoulder.
As shown in Figure 2, generally, when position signalling flip flop equipment is located at (i.e. Polluted area) above pedestal 12, when detected equipment 13 is located at (i.e. safety zone) below pedestal 12, analyze known, the possible leakage path of dusty gas is: dusty gas enters from A or B place, is revealed by the gap between axle 10 and baffle plate supporting base 4; Dusty gas enters from C, is revealed by the gap between axle 10 and sleeve 11.
Improvement of the present invention is, on baffle plate supporting seat 4 and axle 10 first shaft shoulder end face between sealing gasket 5 is set, and, arrange between baffle plate supporting seat 4 and sleeve 11 and be sleeved on axle 10 and the flexible sealing shroud 7 moved with axle 10, the middle part of flexible sealing shroud 7 has one section of telescopic structure, its two ends have the chimb extended out, the chimb of flexible sealing shroud 7 one end is fixed on the lower surface of baffle plate supporting base 7 by screw and gland 6, the chimb of the other end is fixed on the upper surface of sleeve 11 by screw and gland 6, like this when axle 10 moves up and down, flexible sealing shroud 7 does stretching motion with axle 10, no matter ensure it is stationary state or motion state, dusty gas is not all revealed.
By adopting said structure to arrange, when dusty gas enters from A, entered by sealing gasket 5 preventing pollution gas; When dusty gas enters from B or C place, by flexible sealing shroud 7, dusty gas is isolated, thus blocked all possible leakage approach.
In addition, the spring 9 be wrapped on axle 10 is provided with between the bottom of axle 10 and sleeve 11; One end of spring 9 is against on the step be located in sleeve 11, and the other end is against the second shaft shoulder place on axle 10.
Pedestal 12 is also provided with support plate 2, and the bottom of support plate 2 is fixed by screws on pedestal 12.Proximity switch 1 is docked to level detection sensor, and proximity switch 1 is fixed on the top of support plate 2 by two nuts.
Under preferable case, the middle part of axle 10 is provided with spacing hole 14, and the top of sleeve 11 is provided with pin-and-hole and also passes the spacer pin 8 in axle 10 upper limit hole 14 through pin-and-hole; When axle 10 moves to upper extreme position, spacer pin 8 is positioned at the lower end of spacing hole 14; When axle 10 moves to lower limit position, spacer pin 8 is positioned at the upper end of spacing hole 14.
Here spacer pin 8 has two functions: first is guiding, prevents axle 10 from producing rotation, causes the signal mask 3 being fixed on axle 10 upper end to depart from assigned address, cannot trigger proximity switch 1; Second is spacing, the stroke that moves up and down of axle 10 is limited in the stroke in axle 10 upper limit hole 14, namely under system is not subject to External Force Acting situation, restrictive axes 10 is in the distance of spring 9 moved downward, when axle 10 be subject to detected equipment 13 apply to lifting force time, the upper extreme position of axle 10 motion is limited by spacer pin 8, when the motion of detected equipment 13 is put in place, axle 10 is pushed to upper extreme position and triggers proximity switch 1, control the movement position of detected equipment 13 simultaneously, prevent mechanical collision.
When the present invention works, when first making detected equipment 13 move to assigned address, apply acting force in the lower shaft end of axle 10, by axle 10 upwards jack-up, signal mask 3 moves to upper extreme position with axle 10, simultaneously by the horizontal level of adjustment proximity switch 1, makes signal mask 3 reach the operating distance triggering proximity switch 1, proximity switch 1 is triggered, and sends the signal that puts in place; When detected equipment 13 is not in place, be applied to the lower shaft end of axle 10 without external force, under the effect of self gravitation and spring 9, axle 10 moves downwardly to lower limit position, and signal mask 3 is away from proximity switch 1.
Structure of the present invention is not limited to the embodiment described in embodiment, and those skilled in the art's technical scheme according to the present invention draws and other embodiment belongs to technological innovation scope of the present invention equally.
