Description of drawings
Fig. 1 is the scheme drawing of the control group embodiment of the utility model safety component.
Fig. 2 is the scheme drawing of the utility model elevator safety loop embodiment.
The specific embodiment
For the purpose, technical scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
As shown in Figure 1; It is the scheme drawing of the control group embodiment of the utility model safety component; This control group is used for realizing the anxious open and close that stop relay of elevator safety loop elevator, and wherein the anxious two ends of stopping relay of elevator are respectively via first power lead and second source wire joint L terminal and the N terminal to power supply.In the present embodiment, control group comprises K switch, capacitor C, the first terminal, second terminal and the 3rd terminal, and wherein the first terminal and second terminal are used for control group is concatenated into first power lead, and the 3rd terminal then is used to connect the second source line.
The two ends of K switch are connected respectively to the above-mentioned the first terminal and second terminal, connect the 3rd terminal and an end of electric capacity is connected to the first terminal or second terminal and the other end.Through the bonded assembly structure of above-mentioned three terminals, can K switch be concatenated on first power lead and with capacitor C and jump between first power lead and the second source line, K switch can realize the anxious open and close that stop relay of elevator like this, thereby realizes elevator safety.
Above-mentioned K switch can be electromagnetic relay, mechanical switch, photoelectric switch or switching valve etc.The safety component of controlling these switches then can be velocity limiter, safety tongs, emergency stop push button, Emergency Exit switch, pit switch or limit switch etc.
As shown in Figure 4, be the scheme drawing of the utility model elevator safety loop embodiment.This elevator safety loop comprise a plurality of safety components, with the cooresponding a plurality of K switch of these a plurality of safety components 1, K2 ..., Kx and with the cooresponding a plurality of capacitor C of above-mentioned a plurality of switches 1, C2 ..., Cx.Wherein, Above-mentioned a plurality of switch series is connected on the L terminal of power supply; The two ends of each in a plurality of electric capacity then are connected on the L terminal and N terminal of power supply; And the end that electric capacity is connected to power supply L terminal lays respectively at the same side to inductive switch, for example capacitor C 1, C2 ..., Cx be connected respectively to K switch 1, K2 ..., Kx the right side.
Above-mentioned K switch 1, K2 ..., Kx can be in electromagnetic relay, mechanical switch, photoelectric switch or the switching valve one or more, each safety component can make switch break off for example mechanical contact, electric signal control etc. through different modes.These safety components can be velocity limiter, safety tongs, emergency stop push button, Emergency Exit switch, pit switch or limit switch etc.
Through with K switch 1, K2 ..., Kx is concatenated into the L terminal of power supply, the unlatching that can realize the elevator emergency relay is with closed, thereby realizes elevator safety.
And electric capacity itself does not influence the function of elevator safety circuit major loop.But when a certain switch in the elevator safety loop breaks off (the anxious relay that stops of elevator this moment makes the elevator out of service); Then the total capacitance value in the elevator safety loop will produce corresponding the variation; Through the capacitance in the major loop that detects elevator safety loop; Can know that which switch breaks off, thereby detect and the cooresponding safety component of this switch.Like this, just need not to adopt again manual type to get into hoistway, the end, hole, sedan-chair top etc. and locate to investigate one by one the trouble point.
For the ease of the fault location point, above-mentioned capacitor C 1, C2 ..., Cx appearance value identical.
The above; Be merely the preferable specific embodiment of the utility model; But the protection domain of the utility model is not limited thereto; Any technical personnel of being familiar with the present technique field is in the technical scope that the utility model discloses, and the variation that can expect easily or replacement all should be encompassed within the protection domain of the utility model.Therefore, the protection domain of the utility model should be as the criterion with the protection domain of claim.
