The disconnected rope of elevator wire rope based on the light propagation principle of the present utility model monitoring device comprises: laser transimitter, laser pickoff, transmitter rack, receiver holder and a plurality of connecting element.
Laser transimitter is mainly for generation of LASER Light Source.Laser transimitter is fixed on transmitter rack by one or more connecting element (as captive nut), and laser transimitter is arranged at a side of elevator wire rope.
Laser pickoff is fixed on receiver holder by one or more connecting element (as captive nut).Laser pickoff is arranged at the opposite side of elevator wire rope, and laser pickoff and laser transimitter are oppositely arranged (also can be called and arrange in opposite directions or arrange face-to-face), that is to say, in opposite directions spaced apart and establish by elevator wire rope between laser pickoff and laser transimitter.In addition, laser pickoff also is connected with warning device.
Laser pickoff is mainly used in receiving the light that the laser transimitter emission comes.At elevator wire rope, under normal condition, due to the obstruct of elevator wire rope, laser pickoff should not receive the light that laser transimitter sends; And at elevator wire rope under abnomal condition (as certain root/some root wire cable rupture wherein), elevator wire rope completely loses or part has been lost iris action, laser pickoff can receive the light that laser transimitter sends, thereby laser pickoff produces alerting signal, like this, monitoring device of the present utility model can be by the warning device that is connected with laser pickoff to the error state of elevator wire rope reported to the police (as sound/light warning etc.).Above-mentioned wire cable rupture can be specially steel rope and rupture fully by (i.e. fully disconnected rope), and also can be specially steel cable only has part fracture and part to connect (the disconnected rope of part, also can be called broken strand of steel cable).
Transmitter rack and receiver holder can be all tabular support, can certainly be other forms of support.The disconnected rope of elevator wire rope based on the light propagation principle of the present utility model monitoring device can be fixed on by transmitter rack and receiver holder the below of the traction sheave of elevator, certainly, also can be fixed on other suitable positions according to actual conditions.
In addition, the product that above-mentioned laser transimitter and laser pickoff can be chosen respective type according to the actual kind of the existing product based on laser is realized, below by two kinds of dissimilar specific products, the disconnected rope of the elevator wire rope based on the light propagation principle of the present utility model monitoring device is further detailed.
Embodiment mono-, the disconnected rope of the elevator wire rope based on the light propagation principle based on infrared laser monitoring device, specifically as shown in Figure 1.
The disconnected rope of the elevator wire rope based on the light propagation principle in Fig. 1 monitoring device mainly comprises: 1 Infrared laser emission device 4(also can be called line style Infrared laser emission device), 5 infrared laser receptors 5, Infrared laser emission device support 2(also can be called Infrared laser emission device supporting plate), infrared laser receiver holder 6(also can be called infrared laser receiver holder plate), a plurality of Infrared laser emission device captive nut 3 and a plurality of infrared laser receptor captive nut 7.
It should be noted that, because the elevator wire rope shown in Fig. 1 is comprised of 5 steel ropes 1, therefore, the quantity of the infrared laser receptor 5 in the present embodiment is 5; If the steel rope quantity that elevator wire rope comprises changes, the quantity of infrared laser receptor 5 also can change thereupon.Below each device in Fig. 1 is described respectively.

It should be noted that, because the elevator wire rope shown in Fig. 3 is comprised of 5 steel ropes 1, therefore, the laser-correlation switch projector 8 in the present embodiment and the quantity of laser-correlation switch receptor 9 are 5; If the steel rope quantity that elevator wire rope comprises changes, the quantity of laser-correlation switch projector 8 and laser-correlation switch receptor 9 also can change thereupon.Below each device in Fig. 3 is described respectively.
Laser-correlation switch projector 8 is fixed on laser-correlation switch transmitter rack 10 by tightening of laser-correlation switch projector captive nut 11, and laser-correlation switch transmitter rack 10 is arranged at a side of elevator wire rope.The light sent due to laser-correlation switch projector 8 has focus characteristics, and therefore, the present embodiment need to arrange the disconnected rope monitoring that 5 laser-correlation switch projectors 8 are realized 5 steel ropes.
5 laser-correlation switch receptors 9 all are fixed on laser-correlation switch receiver holder 13 by tightening of laser-correlation switch receptor captive nut 12, and 5 laser-correlation switch receptors 9 can be two row's alternative form settings, certainly, if the spacing between two adjacent steel ropes 1 is enough large, 5 laser-correlation switch receptors 9 also should be all right with form setting in one line.
5 laser-correlation switch receptors 9 are arranged at the opposite side of elevator wire rope by laser-correlation switch receiver holder 13, and are oppositely arranged with laser-correlation switch projector 8.5 respectively corresponding 5 steel ropes 1 of laser-correlation switch receptor 9, and 5 laser-correlation switch receptors 9 can be connected with same warning device.
An object lesson of the corresponding relation between setting position on laser-correlation switch receiver holder 13 of 5 laser-correlation switch receptors 9 and 5 laser-correlation switch receptors 9 and 5 steel ropes 1 as shown in Figure 4.
When the arbitrary steel rope 1 in elevator wire rope all do not have the fracture phenomenon, the laser of launching due to 5 laser-correlation switch projectors 8 is radiated at respectively on 5 steel ropes 1, and stopped by this 5 steel ropes 1, therefore, 5 laser-correlation switch receptors 9 all do not receive any laser signal.
In elevator wire rope appoint one or more steel rope 1 fracture phenomenons the time, the steel rope 1 that the laser of launching due to laser-correlation switch projector 8 corresponding to steel rope 1 with fracture can not be ruptured stops and on the direct irradiation laser-correlation switch receptor 9 corresponding at the steel rope 1 with fracture, therefore, corresponding laser-correlation switch receptor 9 can receive laser signal, thereby the alerting signal that corresponding laser-correlation switch receptor 9 produces is transferred to connected warning device, and the alarm message of warning device output (as sound/light warning etc.) can make service personnel know in time the breaking state of elevator wire rope.
The above is only preferred embodiment of the present utility model, not the utility model is done to any pro forma restriction, although the utility model discloses as above with preferred embodiment, yet not in order to limit the utility model, any those skilled in the art are not within breaking away from the technical solutions of the utility model scope, when the technology contents that can utilize above-mentioned announcement is made a little change or is modified to the equivalent embodiment of equivalent variations, in every case be the content that does not break away from technical solutions of the utility model, any simple modification of above embodiment being done according to technical spirit of the present utility model, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
