1. this control monitor unit is by disconnected strand reminding unit, after receiving the information of disconnected strand of traction steel-cable fracture of wire, by automatic lock ladder unit, it is the own feature operation of elevator, automatically elevator is returned safe floor, door-opened elevator, stop, avoiding fault to continue to extend, the generation of containment safety misadventure improves the elevator Operation safety;
2. 360 ° collection dimension is adopted in the information acquisition of disconnected strand of traction steel-cable fracture of wire, and disconnected burst switch motion is sensitive, reliable, and the information acquisition accuracy rate is high.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples, in the accompanying drawing:
Fig. 1 is the electrical schematic diagram of the disconnected strand control monitor unit of the utility model elevator dragging wire rope.
Fig. 2 is the action flow chart of the disconnected strand control monitor unit of the utility model elevator dragging wire rope.
The specific embodiment
As shown in Figure 1, the disconnected strand control monitor unit of the utility model elevator dragging wire rope comprises automatic lock ladder unit and disconnected strand reminding unit.
Automatic lock ladder unit comprises the terraced switch 1 of lock and relay A, locks terraced switch 1 one contacts and is connected with zero-power line by relay A, and this is locked terraced switch 1 another contact and is connected with power firestreak.
A disconnected strand reminding unit comprises disconnected strand switch 2, relay B and hand reset button 3.
Disconnected burst of switch 2 one contacts are connected with power firestreak, and these disconnected strand switch 2 another contacts connect hand reset button 3 one contacts, and these hand reset button 3 another contacts are connected with zero-power line through relay B.
Disconnected strand switch 2 comprises the switch actuating handle of strip, during installation, must will break strand switch 2 the switch actuating handle along elevator dragging wire rope laterally and adjacent setting with elevator dragging wire rope (when the neighbor distance of switch actuating handle and elevator dragging wire rope should guarantee that disconnected thigh appears in steel wire, handle can be touched by toggle switch in disconnected burst of termination of perk, for example, the neighbor distance of switch actuating handle and elevator dragging wire rope can be got more than or equal to 1 centimetre, less than or equal to 3 centimetres, can obtain preferably monitoring effect), projection and these elevator dragging wire rope of lever piece (being that the switch actuating handle can operate the part that it is pass on) in the axis plane of its adjacent elevator dragging wire rope of passing on of this switch actuating handle all intersects, and all can trigger disconnected strand switch 2 actions when occurring disconnected burst to guarantee disconnected strand switch 2 arbitrary adjacent traction steel-cables.
Relay B comprises two open contacts, and its open contact a is connected in parallel on the two ends of disconnected strand switch 2, and open contact b is connected in parallel on the two ends of the terraced switch 1 of lock.
In order to strengthen the effect of reporting to the police, annunciator 4 is set.Annunciator 4 is connected in parallel on the two ends of relay B.In order to strengthen the effect of reporting to the police, but the also relay of select tape lamp of relay B.In other embodiments, annunciator 4 is not set, relay B does not adopt the relay with lamp, does not affect the realization of the object of the invention.
A disconnected strand switch 2 can parallel connection be provided with two, and this two disconnected strand switch 2 is separately positioned on the both sides of traction steel-cable.A disconnected strand switch 2 can only arrange one, and this disconnected strand switch 2 is separately positioned on the either side of traction steel-cable.
As shown in Figure 2, the motion flow of disconnected strand of control monitor unit of the utility model elevator dragging wire rope is as follows: and open contact a and the equal adhesive of open contact b → relay A action → elevator auto-returned base station → door-opened elevator, the static state of a disconnected burst switch motion → disconnected gang of switch two closings of contact → relay B action → relay B stops → and maintainer's machine room upper is in time searched steel rope fault, the position of the thigh that breaks.Relay A is the original fire-fighting of elevator or locks terraced relay; Relay B is the verification relay of steel rope fault, disconnected thigh, is under normal circumstances off position.After relay B action, need to disconnect this relay B by hand reset button 3.Annotate: recover by other means elevator for preventing other staff, as use the fire-fighting key of management agency's monitoring and control centre, can only remove machine room hand reset relay B by elevator service personnel, to guarantee in time to find and to get rid of because of other staff's maloperation the fault of traction steel-cable fracture of wire, disconnected thigh.
