Description
Technical field
The invention belongs to the state inspection field of elevator traction machine or elevator, be specifically related to a kind of testing agency that elevator machine brake opening and closing action is amplified, is the improvement to existing testing agency.
Background technology
When the condition checkout gear of the elevator machine brake in the prior art all was the drg action, the push rod on the Moving plate touched the micro-switch contact, and the action of micro-switch contact opens and closes feedback of status to control system with drg.Because the actuating length that drg opens and closes is too little and frequent, affected the regular event of micro-switch, had the phenomenon of misoperation, so only have the actuating length that increases the micro-switch contact, the regular event of guarantee micro-switch prevents the phenomenon of misoperation.Find through retrieval, for example Chinese invention patent Granted publication CN2923626Y discloses " a kind of mechanism for detection of brake status ", this mechanism adopts lever amplification principle that the signal of feedback is amplified to realize, it comprises " Z " type support, push rod, pad, reed etc., micro-switch and reed are rack-mount, be fixed on together again on the quiet plate of drg, the push rod actuating spring, reed presses the contact action of micro-switch, and the distance of reed attachment point is arrived in the contact of micro-switch greater than the lever contact to the distance of reed attachment point.Move although this structure has been amplified the adhesive of opening of drg, because reed is metal strip, an end is installed on the support by bolt and pad, and reed is out of shape easily in moving frequently, and fatigue damage loses measuring ability, causes potential safety hazard.
For example European patent Granted publication EP1445784B1 discloses " a kind of micro-switch that lever is installed " again, this micro-switch comprises electrical contact, electrical contact is by a plunger action, this plunger contacts with a switch lever, lever forms an angled lever by rigid joint in the middle of this switch lever and, and angled lever is connected on the sidewall on chassis by flexible connector.The advantage that this structure has is: when a/b=3, the actuating length that drg is opened adhesive has been exaggerated 3 times.Also there is following shortcoming in this structure in actual use: at first, with the action fulcrum of flexible connector as angled lever, open or moment of adhesive at drg, because flexible connector is elastomeric, the fulcrum of angled lever is unfixing, and accurately the deterministic force brachium is short, and flexible connector also easily distortion after Reusability, fatigue damage loses measuring ability, causes potential safety hazard; Secondly, on the chassis side wall that is installed in micro-switch of angled lever integral body, be subjected to the restriction of installing space, the size of angled lever can not be excessive, and namely magnification factor is limited.
In view of above-mentioned prior art, the applicant has done useful design, has found solution to the problems described above, and to be proved be effective, and technical scheme described below produces under this background.
