In figure, fork frame 1, vehicle frame 2, displacement sensor for pull rope 3.
Specific embodiment
The core of the utility model is to provide a kind of fork height monitoring device, can monitor in real time and accurately understand arrival
Pitch adjustable height information.
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
As shown in Figure 1-Figure 3, the utility model discloses a kind of fork height monitoring devices, including displacement sensor for pull rope
3 and the display control unit that is electrically connected with displacement sensor for pull rope 3, wherein displacement sensor for pull rope 3 is for monitoring pallet fork liter
Elevation information drops, and displacement sensor for pull rope 3 and vehicle frame 2 are connected and the fork frame 1 of drawstring and pallet fork is connected, and drawstring is with fork frame 1
It goes up and down simultaneously.Display control unit is as signal processing and display device, for showing what displacement sensor for pull rope 3 transmitted
Pallet fork 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 a threaded wheel hub by stretchable stainless steel cable, 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 the fixed position of vehicle frame 2, 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 guarantees 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 moving distance.It measures defeated
Out signal it can be concluded that 1/ pallet fork of fork frame displacement, direction or rate.
A kind of fork height monitoring device that this programme provides passes through displacement sensor for pull rope going up and down in real time by pallet fork
Elevation information is converted into electric signal transmission to display control unit, and display control unit calculates shipment based on the received electrical signal
Fork shows highly and by screen that final operator can monitor in real time and accurately recognize pallet fork adjustable height in real time
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.
