Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in further detail, but not as to restriction of the present utility model.
As it is shown in figure 1, a kind of elevator pine disconnected rope real-time monitoring device processed based on curent change of the present utility model, including driving module 1 and detection module 2.
Drive module 1 to include: a regulating wheel 11, be used for propping up elevator wire rope 3 and sense its tension force and move horizontally; Regulating wheel 11 applies to point to the spring 12 of the elastic force of elevator wire rope 3; The resistance adjusting lever 13 that level of synchronization moves it is connected with regulating wheel 11. Regulating wheel 11 and both resistance adjusting levers 13 relative position are fixed, and move integrally along with the spring 12 length change caused by elevator wire rope 3 tension force.
Resistance adjusting lever 13 can be �� type or �� type, and including horizontal segment 131 and vertical section 132, horizontal segment 131 is connected with regulating wheel 11, and vertical section 132 is connected with the slide plate 211 of slide rheostat 21. Or, resistance adjusting lever 13 can also be other shapes, as long as having the connecting portion with regulating wheel 11 and having and the connecting portion of slide rheostat 21 slide plate 211. In the present embodiment, resistance adjusting lever 13 is in �� type. The horizontal segment 131 of resistance adjusting lever 13 is installed on guiding trestle 15, this guiding trestle 15 is fixed, such as it is fixed in hoistway, guiding trestle 15 is provided with guiding installation position by horizontal direction, the horizontal segment 131 of resistance adjusting lever 13 runs through this guiding installation position and can be moved along it so that resistance adjusting lever 13 can only move horizontally and cannot move up and down. In the present embodiment, guiding trestle 15 is in �� type, and two sides are respectively equipped with the relative installing hole in position and constitute guiding installation position, and the horizontal segment 131 of resistance adjusting lever 13 runs through two installing holes and can be moved along it.
The limiting section 14 of the power for accepting spring 12 it is provided with on horizontal segment 131 surface of resistance adjusting lever 13. Preferably, horizontal segment 131 outer surface of resistance adjusting lever 13 has screw thread, is connected with tension adjustment nut, constitutes the limiting section 14 of adjustable springs tension force, thus the Tensity size regulating spring 12 can be arranged according to steel wire rope tension and designing requirement.
In the present embodiment, spring 12 adopts compression spring, is socketed on horizontal segment 131, and limiting section 14 is then located between regulating wheel 11 and guiding trestle 15, spring 12 one end props up guiding trestle 15, and the other end props up limiting section 14 to its elastic force applying to point to elevator wire rope 3. Or, spring 12 can also adopt extension spring, it is socketed on horizontal segment, limiting section is located at the position between horizontal segment end or end and guiding trestle, spring one end props up guiding trestle, the other end holds limiting section to its elastic force applying to pull to elevator wire rope, it is possible to play the effect identical with the present embodiment.
If resistance adjusting lever 13 is �� type, its vertical section 132 move to guiding trestle 15 outside conflict and namely stop, such that it is able to control the displacement stroke of resistance adjusting lever 13. Or, when resistance adjusting lever 13 is in �� type, such as the present embodiment, its vertical section 132 move to guiding trestle 15 inside conflict and namely stop, thus the displacement stroke of resistance adjusting lever 13 can also be controlled. It is furthermore preferred that the horizontal segment 131 of resistance adjusting lever 13 is provided with stop nut 16 away from one end of regulating wheel 11, such that it is able to according to the actual displacement stroke regulating resistance adjusting lever 13. The displacement stroke of resistance adjusting lever 13 preferably matches with the adjustment stroke of slide rheostat 21.
