Embodiment 1
The present embodiment provides a kind of fork truck, and with reference to Fig. 1, it includes the row being made up of vehicle frame 10 and wheel and drive axle etc.
Mechanism is sailed, remaining part is all installed on vehicle frame 10 by installation foundation of traveling mechanism, so as to constitute the fork truck of the present embodiment.
As depicted in figs. 1 and 2, near vehicle frame 10 front end be disposed with switchable gearbox 21, clutch 22 with
And motor 11, by the connection gearbox 21 of clutch 22, gearbox 21 drives again vehicle wheel rotation to the output shaft of motor 11.Tool
Body ground, the two ends of rotor of motor 11 is connected with the first output shaft (not shown) and the second output shaft (not shown),
Wherein the first output shaft is connected with the clutch, and the second output shaft is used to drive hydraulic pump 31 to work, and hydraulic pump 31 is ordered about again
Hydraulic jack action, so as to complete the control to Working mechanism.
With reference to Fig. 3 and Fig. 4, the fork truck of the present embodiment has made rational arrangement to the structure arrangement of engineering truck, specifically such as
Shown in Fig. 4, the side relative with hydraulic oil container 32 is provided with controller 35 on vehicle frame 10；Because the front end of vehicle frame 10 is used to hold
Heavy work, therefore the rear end of vehicle frame 10 is provided with counterweight 33, it is storage in battery case 34, battery case 34 in the top of counterweight 33
For the battery of drive motor 11, the front end of battery case 34 arranges the driver seat 41 taken for driver, posture seat 41
Top is provided with blocks frame, prevents falling object from high altitude, it is ensured that driver safety.
In the present embodiment, because gearbox 21 is gearbox capable of reversing, then the output shaft of motor 11 then can be only single
To rotation, the retrogressing of vehicle is completed by the commutation of gearbox 21.So motor 11 may be used for driving Working mechanism action,
As shown in figure 1, the second output shaft of motor 11 drives hydraulic pump 31 to work, hydraulic pump 31 connects hydraulic oil container 32 with hydrodynamic pressure
Cylinder action.It can be seen that in the present embodiment, only can simultaneously drive traveling mechanism and Working mechanism using a motor 11, compare
The set-up mode of 4 motor 11 is at least needed to have a clear superiority in prior art.First, most intuitively, motor 11 is counted
After amount is reduced, the production cost of engineering truck is also decreased；Second, the quantity of motor 11 is reduced and also cause the having of vacateing of vehicle frame 10
Limit space can be used to deposit the battery of motor 11, so as to lift the continuation of the journey of electronic engineering truck, solve current electric motor car continuation of the journey
Difference, compared to mobile engineering car can not persistently operation technological deficiency；3rd, when in use, it stops and changes electronic engineering truck
To action it is very frequent, because the motor 11 of the present embodiment need not become the rotation direction of exchanging rotor in commutation process, electricity
Rotation direction of the motivation 11 before and after commutation can be consistent, and only can just complete traveling by clutch 22 and gearbox 21
The commutation and stopping of mechanism, therefore compared to general electronic engineering truck, the fork truck of the present embodiment motor in commutation process
11 energy consumption is less, the electric quantity consumption of motor 11 can be saved, so as to improve the continuation of the journey of electronic engineering truck.
It should be noted that：Used as one kind deformation of above-mentioned embodiment, Working mechanism can also be that air pressure drives or machine
Tool drives, and not only limits to and hydraulic-driven, and those skilled in the art can select Working mechanism according to actually used demand
Set-up mode.
In the present embodiment, the two ends of rotor of motor 11 connects respectively the first output shaft and the second output shaft, two outputs
Axle drives respectively traveling mechanism and Working mechanism, so drives traveling respectively by different motors compared in general engineering truck
Mechanism and the set-up mode of Working mechanism, the layout more compact and reasonable of the fork truck of the present embodiment, take full advantage of on vehicle frame 10
Space, make all to be utilized before and after motor 11, so as to vacate bigger battery accommodating space.
Fork truck is a kind of common in workshop transhipment machinery, is hinged in the front end of fork truck and is provided with shelf 42 and slip sets
The pallet fork on shelf 42 is put, shelf 42 and pallet fork receive respectively hydraulic jack drive action, so as to complete to carry.As shown in figure 3,
Shelf 42 are driven by inclined hydraulic oil cylinder 43, shelf 42 is deflected around jointed shaft, and so as to complete to dig, shovel action, pallet fork is received
Raise-lower hydraulic oil cylinder 44 drives, so as to complete raising action.
In the present embodiment, the front-wheel 12 of the front end of vehicle frame 10 with diameter greater than the rear end of vehicle frame 10 trailing wheel 13, in general front-wheel
12 are used for load-bearing, and trailing wheel 12 is used to turn to, therefore less trailing wheel is easy to fork truck to complete to turn in less space, so as to convenient
Walk under the environment such as workshop.As shown in Figure 3, the top of driver seat 41 is additionally provided with and blocks frame.
But it should be recognized that the fork truck described in embodiment 1 is not limited only to apply in fork truck field, other are can also be
The engineering truck of form.
In the another embodiment of fork truck, shelf 42 are fixedly disposed on vehicle frame 10, and Working mechanism is only comprising liter
Descending liquid compressing cylinder 44 and pallet fork, and do not include inclined hydraulic oil cylinder 43, the simpler fork truck of this structure, only rely on pallet fork
The carrying that case fills object is completed, range of application is also very wide.
Obviously, above-described embodiment is only intended to clearly illustrate example, and not to the restriction of embodiment.It is right
For those of ordinary skill in the art, can also make on the basis of the above description other multi-forms change or
Change.There is no need to be exhaustive to all of embodiment.And the obvious change thus extended out or
Among changing still in the protection domain of the invention.
