Abstract

The utility model relates to an elevator rope head plate integral bearing sensor which comprises an elevator rope head plate, wherein a plurality of rope penetrating holes are arranged on the rope head plate. The lower end face of the rope head plate is provided with one or two holes, the hole of the rope head plate face, which is not penetrated, is stuck with a strain piece and the strain piece is matched with the rope head plate to form a sensor. The elevator rope head plate integral bearing sensor can be directly arranged, and has the advantages of convenient installation and simple manufacturing technique. Because signals are directly obtained from the rope head plate, the elevator rope head plate integral bearing sensor has high accuracy and sensitivity.

Description

The integrated bearing sensor of elevator rope hitch plate

The bearing sensor of elevator is a safety guard of realizing that elevator safety operation, underloading, semi-load, fully loaded, overload protection, warning, control and load capacity show, and therefore, its stable performance, reliable in quality are the most primary requirements of bearing sensor.

At present, China is normally used to be traditional general mount type bearing sensor, its installation method is: two rope hitch plates are installed in cab, and bearing sensor is positioned between two rope hitch plates, when elevator moves, because the pressure effect of two rope hitch plates, and make bearing sensor produce corresponding discernible signal, thereby realize control to elevator, existing bearing sensor remains in following shortcoming: installing needs to be equipped with corresponding mechanical device, and the installation steps complexity is not to directly act on the strain-gauge owing to bear a heavy burden, but by corresponding mechanics indirectly-acting in strain-gauge, accuracy, negative sensitivity is all undesirable; Because what adopt is standard transducer, its supporting part needs to install separately for independently, non-elevator special use, and also price is higher.Therefore be necessary to provide a kind of reaction more timely, the sensor that accuracy is higher.

The purpose of this utility model provides the integrated bearing sensor of a kind of elevator rope hitch plate, and this sensor is installed very convenient, and reaction is timely, the accuracy height.

For achieving the above object, the utility model is taked following design plan: the integrated bearing sensor of this elevator rope hitch plate comprises the elevator rope hitch plate, and the rope hitch plate lower surface has 1-2 hole, posts strain-gauge on the rope hitch plate face that Kong Wei gets through.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is the constitution diagram of installing and using of traditional bearing sensor

Fig. 2 is the utility model structural representation

Fig. 3 is the birds-eye view of Fig. 2

Fig. 4 installs and uses scheme drawing for the utility model

As shown in Figure 1,1 is the combination of traction fag end, and 2 is rope hitch plate, and 5 is supporting plate, 7 is base plate, and bearing sensor 6 is installed between supporting plate and the base plate, when elevator moves, because the pressure effect of two rope hitch plates makes bearing sensor produce discernible signal, thereby realizes the control to elevator.3 is stay-bolt, and 4 put the beams in place.

Among Fig. 2, Fig. 3, Fig. 4, adorn a rope hitch plate in traction fag end combination 1, on this rope hitch plate strain-gauge is installed, i.e. the utility model product is among the figure, 2 is rope hitch plate, have a plurality of eyelet holes 10 on the rope hitch plate, have 1-2 hole 9 on the rope hitch plate 2 from the lower surface, post strain-gauge 8 not getting through on the rope hitch plate face in hole, strain-gauge can adopt BP120-10AA, its sensitivity 2-2.5mv/v (former traditional sensors sensitivity 1.0-1.2mv/v).When elevator rose, rope hitch plate was stressed, and caused rope hitch plate upper stress strain-gauge occurrence positions, and strain value is converted to electric signal by instrument, so that show load capacity, mode of operation indication, trouble diagnosing, overload warning, noise reductions etc., the glue market of sticking strain-gauge is on sale, for example H-611.

The utility model advantage is: simple installation, manufacture craft is simple, because directly obtain letter from rope hitch plate Number, namely directly obtain signal, accurately; And highly sensitive.

Claims

1, the integrated bearing sensor of a kind of elevator rope hitch plate, it is characterized in that: it comprises the elevator rope hitch plate, the rope hitch plate lower surface has 1-2 hole, posts strain-gauge on the rope hitch plate face that Kong Wei gets through.
