Description

Elevator brake reliability detecting device
Technical field
The utility model relates to elevators field, is specifically related to elevator brake reliability detecting device.
Background technology
Elevator is the widely used vehicle, and safe and reliable operation has been the topic of social concerns.Drg is one of key safety parts of elevator safety reliability service, and it is the parts of reliable stop under elevator normally starts stopping and abnormal condition.A large amount of accident cases proves, the one of the main reasons that elevator human casualty accident occurs, and is derived from misfunctioning of brake, causes elevator to be rushed to summit, the phenomenon such as the end, shearing of squatting causes ill effect, so ensure that drg normal reliable is opened and closed most important.At present, some producer adds detector switch to drg, but the actuating length of switch is less, and drg easily occurs that misoperation causes its reliability uncertain, and this exists certain hidden danger to the safe and reliable operation of elevator.
Summary of the invention
For above-mentioned deficiency of the prior art, the utility model provides a kind of elevator brake reliability detecting device, and this device utilizes lever principle that elevator brake detector switch can be run and close by reliable Detection drg normal safe.
To achieve these goals, the technical solution adopted in the utility model is as follows:
A kind of elevator brake reliability detecting device, comprise drg motion block, quiet piece of drg, detector switch, action push rod and retracing spring, described detector switch is arranged on above quiet piece of drg, described action push rod is arranged on above drg motion block, drg motion block is connected with the second limited post (15) by the first limited post (14) with quiet piece of drg, described elevator brake reliability detecting device also comprises amplification bar and retracing spring, described amplification bar is flexibly connected by rotating shaft with quiet piece of drg, amplify the first coupling end of bar to be connected with the detector switch contact of detector switch, described amplification bar second coupling end and action ejector pin contact, retracing spring respectively with detector switch seat, amplify bar and contact.
Quiet to amplification bar and drg piece is flexibly connected by rotating shaft by the utility model, when action push rod is to amplification bar second coupling end action, under leverage, amplifies bar first coupling end and touch detector switch contact, elevator brake is opened, and detector switch starts to detect action.The vertical distance of amplifying the rotating shaft of bar first coupling end distance is 3 times of the distance of amplifying the rotating shaft of bar second coupling end distance, therefore detector switch also can amplify 3 times along the forced stroke of direction of action, thus effectively reduce the misoperation of brake switch, improve the reliability of elevator brake, avoid the generation of elevator safety accident.
Further, described amplification bar first coupling end and amplification bar second coupling end are that benchmark runs in the horizontal direction with rotating shaft.Amplifying bar first coupling end and amplifying bar second coupling end is that benchmark runs in the horizontal direction with rotating shaft, and better the convenient bar that amplifies carries out action with relative coupling end.
Further, described detector switch contact is greater than the horizontal throw of action push rod to rotating shaft to the horizontal throw of rotating shaft.Detector switch contact is greater than the horizontal throw of action push rod to rotating shaft to the horizontal throw of rotating shaft, and this can better play the enlarging course effect of amplifying bar.
Further, spring is provided with between described detector switch and amplification bar.Between described detector switch and amplification bar
Be provided with spring, convenience amplification bar 2 when drg motion block resets can set back and put, and makes the more smooth and easy convenience of detection operation of elevator brake.
The utility model elevator reliability detecting device, by arranging amplification bar, improves the sensitivity of detector switch, solves the less technical matters causing drg easily to occur misoperation of stroke of detector switch in prior art, improves the safety performance of elevator.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
The utility model elevator brake reliability detecting device comprises drg quiet piece 5, drg motion block 6, detector switch 1, action push rod 7, amplifies bar 2 and retracing spring 16.Drg is provided with the first screw 10 and the second screw 11 for quiet piece 5, drg motion block is provided with the 3rd screw 12 and the 4th screw 13, first limited post 14 is by the first screw 10 and the 4th screw 13 connecting brake quiet piece 5 and drg motion block 6, second limited post 15 is by the second screw 11 and the 3rd screw 12 connecting brake quiet piece 5 and drg motion block 6, detector switch 1 is arranged on above drg quiet piece 5, action push rod 7 is arranged on above drg motion block 6, the side that drg is quiet piece 5 is provided with rotating shaft 8, amplify bar 2 to be flexibly connected by rotating shaft 8 for quiet piece 5 with drg, amplify bar first coupling end 3 to contact with detector switch contact 9, retracing spring 16 is provided with between detector switch seat and amplification bar 2, amplify bar second coupling end 4 to contact with action push rod 7, amplify bar first coupling end 3 parallel in the horizontal direction with amplification bar second coupling end 4, detector switch contact 9 is 3 times that action push rod 7 arrives the horizontal throw of rotating shaft 8 to the horizontal throw of rotating shaft 8, amplifying bar first coupling end 3 apart from the vertical distance of rotating shaft 8 is amplify 3 times of vertical distance of bar second coupling end 4 apart from rotating shaft 8.
