Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearly, clearly, referring to the accompanying drawing embodiment that develops simultaneously, the utility model is further described.
Embodiment 1
Present embodiment discloses a kind of bolt-type safety control structure for elevator, see Fig. 1, this safety control vibrational power flow has four set pins 100, be symmetricly set between two respectively lift car 20 above and below.Four set pins 100 are placed in elevator hoistways 10 inside, be fixedly installed on body of wall 30, each set pin 100 is all connected with actuating unit (not drawing in figure), and this actuating unit drives set pin 100 transversal stretching action (in Fig. 1, arrow represents the direction of action of set pin 100).During work, actuating unit, after lift car 20 arrival floor stops (elevator door open before), drives set pin 100 to stretch out, and four set pins 100 jointly restriction lift cars 20 move up or down; When elevator completes transport action (elevator closes behind the door), when needing to continue rising or down maneuver, actuating unit drives four set pins 100 to shrink, and removes spacing state.
The safety control structure that the present embodiment proposes can be avoided after lift car 20 arrival floor by actv., emergency case occurs and drops suddenly or rush to summit, greatly improving the safety of elevator.When lift car 20 generation tenesmus suddenly or when rushing to summit, each set pin 100 hinders lift car to continue motion, and due to set pin 100 shorter with the distance of lift car 20, the starting stage that set pin 100 can start to drop or rush to summit in Lift out of order timely realizes the spacing inhibition of actv., make elevator stable stop in floor, its safety is high, is convenient to salvage work simultaneously.
In practical application, four set pins 100 a little more than or a little less than lift car 20, namely in normal operation, each set pin 100 does not come in contact with lift car 20.This setup, on the one hand set pin stretch out or contractive action can not impact the normal work of elevator, on the other hand, after lift car 20 arrival floor, certain deviation may be there is in position, the compatibility of this setup is fine, even if the stop layers position of lift car 20 exists some deviations, also can not collide with the set pin 100 stretched out.
Further, set pin 100 can be got information about in order to make user whether to have stretched out and limit (elevator namely after arrival floor whether safety) to lift car 20, the present embodiment is also provided with testing agency's (not drawing in figure), and whether this testing agency has stretched out and carry out spacing for detecting set pin 100 to lift car 20.This testing agency is provided with indicator lamp (not drawing in figure) simultaneously, put in place when testing agency detects that set pin 100 has stretched out, then send out control signal to indicator lamp, now indicator lamp bright (or indicator lamp bright green), when testing agency detects set pin 100 remarkable action, do not stretch out and carry out spacing to lift car 20, then illustrate to there is larger potential safety hazard, now indicator lamp does not work (or shiny red), tell that this elevator of user exists larger potential safety hazard, do not take.
More concrete, indicator lamp can arrange one or more, can be arranged on lift car 20 inner simultaneously, and the people being convenient to take elevator understands the security situation of elevator by this indicator lamp; Or indicator lamp is arranged on the side of elevator floor door, the people being convenient to prepare to take elevator understands the security situation of elevator by this indicator lamp.
This set structure that the present embodiment proposes, can improve the safety of elevator work greatly, be applicable to transform for old elevator structure, to improve its safety simultaneously.
Embodiment 2
The function of the present embodiment is substantially the same manner as Example 1, unlike, the present embodiment is provided with four grooves corresponding with set pin 100 at the top of lift car 20 and bottom, four set pins 100 stretch out and to insert in four grooves respectively afterwards, and what realize lift car 20 is spacing.
Embodiment 3
The function of the present embodiment is substantially the same manner as Example 2, unlike, the set pin 100 of the present embodiment is separately positioned on top and the bottom of lift car 20, and groove is then arranged on body of wall 30, with set pin 100 one_to_one corresponding.
In practical application, set pin 100 can also arrange eight, is placed in the top of lift car 20 and four angles place of bottom respectively.
Embodiment 4
The function of the present embodiment is substantially the same manner as Example 1, unlike, the present embodiment optimizes the set-up mode of set pin 100.See Fig. 2, set pin 100 arranges two, is separately positioned on the left and right sides of lift car 20.The lateral wall of simultaneously lift car 20 is provided with the groove 200 coordinated with this set pin 100, and during work, after lift car 20 arrival floor stops, two set pins 100 stretch out and insert in groove 200, limit lift car 20 and move up or down.This set structure is more simple and practical, and cost is lower, more meets large-scale production and application.
In practical application, after set pin 100 inserts groove 200, do not come in contact (see Fig. 2) with the inwall of groove 200, this setup, on the one hand set pin stretch out or contractive action can not impact the normal work of elevator, on the other hand, after lift car 20 arrival floor, certain deviation may be there is in position, the compatibility of this setup is fine, even if the stop layers position of lift car 20 exists some deviations, also can not collide with the set pin 100 stretched out.
In practical application, observe set pin 100 intuitively for the ease of user and whether insert in groove 200 the spacing action completed lift car 20, lift car 20 inside or elevator floor door are provided with watch window, user can see the action situation of set pin 100 by window according to the observation intuitively, understands elevator in time and whether there is potential safety hazard.Further, the set pin 100 of the present embodiment is arranged on outside lift car 20, and convenient user observes its action.
In practical application, set pin 100 can be arranged on the original track of elevator (now to be needed to reinforce original track), also can arrange a mounting bracket 300 (see Fig. 2), set pin is fixedly mounted on mounting bracket 300.
Embodiment 5
The present embodiment is basic identical with embodiment 4, unlike, the set pin 100 of the present embodiment is arranged on the upper end (or lower end) of lift car 20, arranges groove 200, see Fig. 3 in the upper end (or lower end) of lift car 20 simultaneously.This setup, can improve on the basis not changing the original shape of lift car, realizes reducing productive costs further.
Embodiment 6
Fixed mechanism in the present embodiment adopts the fit structure (see Fig. 4) of fixed jaw 400 and projection piece 500, in practical application, fixed jaw 400 is provided with cavity 410, the size of this cavity 410 is greater than projection piece 500, after lift car 20 arrival floor stops, fixed jaw 400 stretches out, and makes projection piece 500 snap in cavity 410 (when normally working, fixed jaw 400 and projection piece 500 do not come in contact), complete the spacing work to lift car.
In the present embodiment, see Fig. 4, fixed jaw 400 is arranged on body of wall 30 and (is namely arranged on outside lift car 20), and projection piece 500 is arranged on lift car outer wall, this setup can reduce the improvement cost to lift car 20, simultaneously without the need to the weight of too much increase lift car 20.In practical application, the mounting means of fixed jaw 400 and projection piece 500 is see embodiment 2-5, and such as can be arranged on the outer wall of lift car 20 by fixed jaw 400, projection piece 500 is arranged on body of wall 30.
Should be understood that; application of the present utility model is not limited to above-mentioned citing; for those of ordinary skills, can be improved according to the above description or convert, all these improve and convert the protection domain that all should belong to the utility model claims.
