And the fork frame of drawstring and the pallet fork is connected, the drawstring lifts simultaneously with the fork frame；
The display control unit being electrically connected with the displacement sensor for pull rope, the display control unit are described for showing
Pallet fork adjustable height information.
Preferably, further include the motor being electrically connected with the display control unit in above-mentioned fork height monitoring device
Controller, the electric machine controller are connect with the motor for controlling the pallet fork lifting.
Preferably, in above-mentioned fork height monitoring device, the motor is ac three-phase asynchronous motor.
Preferably, further include the alarm being electrically connected with the display control unit in above-mentioned fork height monitoring device
Device, when the pallet fork adjustable height Information abnormity, the warning device is alarmed.
It can be seen via above technical scheme that a kind of fork height monitoring device that this programme provides, passes through drawstring displacement
The elevation information of pallet fork lifted in real time is converted into electric signal transmission to display control unit, display control unit root by sensor
The real-time height of pallet fork is calculated according to the electric signal received and is come out by screen display, and final operating personnel can monitor in real time
And accurately recognize pallet fork adjustable height information.

Specific implementation mode
Core of the invention is to provide a kind of fork height monitoring device, can monitor in real time and accurately recognize pallet fork liter
Elevation information drops.
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation describes, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
As shown in Figure 1-Figure 3, the invention discloses a kind of fork height monitoring device, including displacement sensor for pull rope 3 with
And the display control unit being electrically connected with displacement sensor for pull rope 3, wherein displacement sensor for pull rope 3 is for monitoring pallet fork lifting
Elevation information, displacement sensor for pull rope 3 is connected with vehicle frame 2 and the fork frame 1 of drawstring and pallet fork is connected, and drawstring is same with fork frame 1
When lift.The goods that display control unit is transmitted as signal processing and display device, for showing displacement sensor for pull rope 3
Pitch adjustable height information.
The function of displacement sensor for pull rope 3 is that the lifting linear mechanical motion of pallet fork is converted into quantifiable telecommunications
Number.Its working principle is that displacement sensor for pull rope 3 is wound on by stretchable stainless steel cable on a threaded wheel hub, wheel hub
It links together with a precision rotation inductor, inductor can be incremental encoder, individual encoders, mixing or conductive modeling
Expect rotating potentiometer, synchronizer or resolver.
In operation, draw-wire displacement sensor 3 is mounted on 2 fixed position of vehicle frame, and drawstring is tied in the fork frame 1 of pallet fork
With pallet fork elevating movement.When movement occurs, drawstring stretching, extension and contraction.One contained spring ensures that the rate of tension of drawstring is constant.Band
The wheel hub of screw thread drives the rotation of precision rotation inductor, exports an electric signal proportional to drawstring displacement distance.It measures defeated
Displacement, direction or the rate of 1/ pallet fork of fork frame can be obtained by going out signal.
A kind of fork height monitoring device that this programme provides passes through displacement sensor for pull rope lifting in real time by pallet fork
Elevation information is converted into electric signal transmission to display control unit, and display control unit calculates shipment according to the electric signal received
Fork is come out highly and by screen display in real time, and final operating personnel can monitor in real time and accurately recognize pallet fork adjustable height
Information.
In the particular embodiment, the fork height monitoring device of this programme further includes being electrically connected with display control unit
Electric machine controller, electric machine controller are connect with the motor of control pallet fork lifting.Specifically, the display control unit is total by CAN
Line connects electric machine controller, and the height parameter of pallet fork is transferred to controller by CAN bus.
Wherein, motor can be ac three-phase asynchronous motor.Electric machine controller is specially CVC600 model controllers.In reality
In border, the model of motor and electric machine controller can according to practical operation it is different select.
In further specific embodiment, the fork height monitoring device of this programme further includes and display control unit electricity
The warning device of connection is alarmed when pallet fork adjustable height Information abnormity.Pallet fork adjustable height Information abnormity situation such as exists
