[0002] An elevator speed limiter is a safety device used to monitor the running speed of an elevator. If the speed of the elevator exceeds a preset limit, the speed limiter will be automatically triggered to activate the braking system or other safety measures to prevent the elevator from running at an excessive speed and ensure the safety of passengers. In the prior art, some elevator speed limiters usually have an electromagnetic trigger mechanism, which can quickly and reliably activate the braking system when the elevator is overspeed.

However, the electromagnetic trigger mechanism drives the switch or actuator through electromagnetic force and thus relies very much on the power supply.

[0023] Embodiment
[0024] As Figures 1-3 As shown, an electromagnet triggering mechanism for an elevator proposed by the present utility model includes an elevator speed limiter body 1 and an electromagnet triggering mechanism 2 provided on the elevator speed limiter body 1. A chassis 111 is fixedly connected to the bottom of the elevator speed limiter body 1. A plurality of circular holes 112 are formed in the chassis 111. The function of the circular holes 112 is to allow bolts to be inserted and then fix the chassis 111 at a specified position. It further includes: a pair of power supplies 3 installed on the side wall of the elevator speed limiter body 1 for successively and continuously supplying power to the electromagnet triggering mechanism 2; a switching mechanism provided on the side wall of the elevator speed limiter body 1 to enable the pair of power supplies 3 to supply power for the continuous operation of the electromagnet triggering mechanism 2; a detection mechanism installed on the elevator speed limiter body 1 to monitor the power of the power supplies 3 and then enable the pair of power supplies 3 to be used alternately.
[0025] Furthermore, the switching mechanism includes a moving connecting rod 5. Connection heads 31 are provided at one ends of the power supplies 3 close to the moving connecting rod 5. Connection abutting blocks 51 that abut against the corresponding connection heads 31 are fixedly connected to both ends of the moving connecting rod 5. Limit clamping blocks 52 that abut against the connection heads 31 are fixedly connected to both ends of the moving connecting rod 5. The function of the limit clamping blocks 52 is to enable the connection abutting blocks 51 at both ends of the moving connecting rod 5 to accurately abut against the corresponding connection heads 31 after moving. A clamping groove 53 that fits and clamps the connection head 31 is formed on one surface of the limit clamping block 52 close to the connection abutting block 51.
[0026] Among them, the detection mechanism includes a telescopic motor 8, a controller 9, and a current monitoring sensor 10 provided on the outer wall of the elevator speed limiter body 1. The current monitoring sensor 10 is a device used to measure the flow of current in real time and convert it into readable electrical signals or data. The output end of the controller 9 is connected to the telescopic motor 8. A pair of second sleeves 81 that tightly fit the telescopic motor 8 on the outer wall of the elevator speed limiter body 1 are sleeved on the telescopic motor 8. The input end of the controller 9 is connected to the current monitoring sensor 10. The telescopic shaft of the telescopic motor 8 is fixedly connected to an insulating telescopic block 11. One end of the insulating telescopic block 11 is fixedly connected to a conductive connection block 6. The connection abutting block 51, the moving connecting rod 5, and the conductive connection block 6 are all made of conductive metal. The end of the conductive connection block 6 away from the insulating telescopic block 11 is fixedly connected to the moving connecting rod 5. The electromagnet trigger mechanism 2 is provided with a trigger rod 21 for conducting current. One end of the trigger rod 21 close to the conductive connection block 6 is fixedly connected to a telescopic spring 7. The material of the telescopic spring 7 is conductive metal. The function is that no matter what the distance between the freely moving conductive connection block 6 and the trigger rod 21 is, it can ensure that the conductive connection block 6 and the trigger rod 21 are energized. The end of the telescopic spring 7 away from the trigger rod 21 is fixedly connected to the conductive connection block 6.
[0027] Furthermore, a first sleeve 4 is sleeved on the power supply 3. A pair of oval holes 41 are opened on the first sleeve 4. Installation screws 481 are provided on both the oval holes 41 and the second sleeves 81. The installation screw 481 is a screw used for fixing and assembling components. They are usually used in conjunction with nuts or threaded holes and are tightened to ensure the stable connection of components.
[0028] In this embodiment, when the elevator needs to use the electromagnet trigger mechanism on the speed limiter, such as Figure 1 shown, after one of the power supplies 3 on the outer wall of the elevator speed limiter body 1 runs out of power after use. At this time, the current monitoring sensor 10 will send a signal to the controller 9 after learning about it. After the controller 9 is started, it will send an instruction to the telescopic motor 8. After the telescopic motor 8 is started, the telescopic shaft drives the insulating telescopic block 11 to move. The insulating telescopic block 11 drives the conductive connection block 6 and the moving connecting rod 5 to move in sequence. As Figure 3 shown, at this time, the moving connecting rod 5 drives one of the connection abutting blocks 51 to disengage from the dead power connection head 31, and then drives the other connection abutting block 51 to move towards the live connection head 31 until the limiting block 52 at one end of the moving connecting rod 5 abuts against the connection head 31. At the same time, after the card slot 53 tightly clamps the connection head 31, the connection abutting block 51 abuts against the connection head 31. It can enable the power supply 3 to supply power to the electromagnet trigger mechanism 2 in sequence through the connection head 31, the connection abutting block 51, the moving connecting rod 5, the conductive connection block 6, the telescopic spring 7, and finally through the trigger rod 21, which is convenient and fast.
