Description
Technical field
This utility model is related to a kind of forklift door frame lifting altitude and limits system.It is applied to the fork with door frame jack up unit
Car.
Background technology
Fork truck in transport operation it is sometimes desirable to carrying bulkload, and goods keep off advance sight line, needing pitch
When goods is moved into freight house by car, the height of freight house is particularly difficult to estimate, because measurement of cargo is excessive, sight line is interfered, substantially
Also it is required for just completing by manpower commander.
Traditional height limiter is usually in corresponding height setting stopping means, mainly limits on mechanical mechanism
Position, rises and rises to corresponding height, then the limit that is stuck is dead, and this mode advantage is that frame for movement is simple to operation, and shortcoming is this structure
Certain restriction can be brought to the height of carrying fork truck goods, with use, mechanical wear also will be increasing.
Content of the invention
The technical problems to be solved in the utility model is：For above-mentioned problem, provide that a kind of structure is simple, use
Convenient forklift door frame lifting altitude limits system, with the flexible lifting altitude limiting door frame.
This utility model be employed technical scheme comprise that：A kind of forklift door frame lifting altitude limit system it is characterised in that：
Including controller, multipath electrovalve, spacing height configuration switch and mast height acquisition device, wherein
Mast height acquisition device, is electrically connected with the controller, for obtaining the real-time height of forklift door frame；
Spacing height configuration switch, is electrically connected with the controller, for setting the maximum height limit of door frame raising；
Multipath electrovalve, is electrically connected with the controller, for controlling forklift door frame raising oil circuit；
Controller, through described mast height acquisition device obtain forklift door frame elevation information, by elevation information with described
The limit level that spacing height configuration switch sets is compared, and judges whether by multipath electrovalve, rises according to comparative result
Rise oil circuit and limit door frame action.
Described mast height acquisition device is the stay wire sensor of measurement door frame vertical displacement.
Described controller electrically connects mode selection switch.
Described controller connects display through CAN.
Described spacing height configuration switch includes being connected to normally running for setting forklift door frame on described controller
The low clearance configuration switch of low clearance and maximum height and height configuration switch, and for setting the height of door frame limit level
Degree configuration switch.
Status indicator lamp and alarm are connected on described controller.
The beneficial effects of the utility model are：This utility model is transferred to the signal of controller by stay wire sensor, can
With the height being limited according to required for the altitude information in instrument, self-defined setting, controller output after reaching desired height
Signal to control door frame raising to multipath electrovalve.
Brief description
Fig. 1 is the schematic block circuit diagram of embodiment.
Fig. 2 is the electrical schematic diagram of embodiment.
Specific embodiment
As shown in Figure 1 and Figure 2, the present embodiment is that a kind of forklift door frame lifting altitude limits system, including controller 1 (Shanghai
The MAX-17-XG of Mai Kaisi mechanized equipment company limited), and electrically connect with controller 1 multipath electrovalve 2, height set
Switch, stay wire sensor 4, display 5 (Murphy Meter PV101) and mode selection switch 6, controller 1 passes through multipath electrovalve 2
Control forklift lifting oil circuit.Status indicator lamp 9 and alarm are further connected with controller 1.
Wherein stay wire sensor 4 is used for measuring the displacement of forklift door frame vertical direction, the housing parts peace of stay wire sensor 4
Dress is fixed on forklift frame, and the bracing wire of stay wire sensor 4 is partly fixed and door frame moving up and down.Height configuration switch bag
Include the low clearance configuration switch 8 being connected on controller 1, height configuration switch 7 and spacing height configuration switch 3, low clearance sets
Fixed switch and height configuration switch are used for setting the normal minimum altitude run of forklift door frame and maximum height, and spacing height sets
Surely switch 3 is used for setting the limit level of door frame.
The operation principle of the present embodiment is as follows：
Using controller 1, first stay wire sensor 4 is carried out with effective length to demarcate to ensure degree of accuracy, determine stay wire sensor
Relation between 4 and mast height.Erect the limit level rising using spacing height configuration switch 3 camber configuration switch opposite house
Demarcated, open the height value needed for height configuration switch sets when door frame reaches required limit level and (record
The now shift value of stay wire sensor 4).
The present embodiment includes limit for height and infinite height both of which, is switched over by mode selection switch 6.
Pattern 1：Unlimited height mode
Now mode selection switch 6 is in " OFF " state, and controller 1 no exports, and multipath electrovalve 2 must not be electric, and work shape
State display lamp goes out.Now press common fork truck pattern work, door frame can free action.
After making highly on mast height ＞, if mode selection switch 6 will be opened, controller 1 through multipath electrovalve 2,
Raising oil circuit limits door frame and rises, and only allows step-down operation it is necessary to wait height just can carry out other liquid after being less than limit level
Press operation.
Pattern 2：Limit for height pattern starts
Now mode selection switch 6 is in " ON " state.
A, when 0 ＜ mast height ＜ limit level, controller 1 no exports, multipath electrovalve 2 must not electricity, display 5 show
Show the mast height coming by the conversion of stay wire sensor 4 shift value, working station indicator goes out.Now press common fork truck pattern
Work, door frame can free action.
B, when mast height=limit level, controller 1 has output, multipath electrovalve 2 electric, display 5 display is logical
Cross the mast height that the conversion of stay wire sensor 4 shift value comes, working station indicator lights.Now door frame rising, anteversion and retroversion
Invalid, only allow to decline.When mast height deteriorates to less than limit level, door frame works by A mode.
