Detailed description of the invention
The following is the specific embodiment of the present invention and combine accompanying drawing, the technical side to the present invention
Case is further described, but the present invention is not limited to these embodiments.
Refer to Fig. 1, Fig. 2, Fig. 3, in a preferred embodiment of the present invention, electric pallet
Car includes vehicle frame 10, is arranged on turning to drive assembly 20, being arranged on vehicle frame of vehicle frame rear
Two pallet forks 30 in front.
Vehicle frame 10 is by the fore shell 11 vertical with pallet fork 30, by the capping of fore shell 11 upper end
Upper cover 12 and the rear casing assembly composition that drive assembly 20 rear end will be turned to surround.
Wherein, rear casing assembly is made up of back cover 13a and squab panel 13b；Back cover 13a
The most curved with squab panel 13b, it is connected formation one accommodation space with fore shell 11 side,
Drive assembly 20 bottom is turned to i.e. to be positioned at this accommodation space.
Hydraulic oil also it is placed with integrated always in the accommodation space that fore shell 11 and upper cover 12 are formed
One-tenth 40 and accumulator 50.The integrated assembly of hydraulic oil 40 is for being turned to drive assembly to carry
For hydraulic oil so that turning to drive assembly that pallet fork can be driven to rise or fall；Accumulator 50
Drive assembly is turned to provide power supply so that turning to drive assembly can promote electronic torr for giving
Jiggering advances or retreats.
Pallet fork 30 is connected by connecting rod rocker arm assembly 60 with fore shell 11.Connecting rod rocker arm assembly
60 include two connecting rods 61, are respectively arranged on the downside of two pallet forks 30, and two connecting rod 61 ends set
It is equipped with roller 62；Pallet fork 30 is provided with the slot rolling 31 corresponding with roller 62 and makes roller
62 can roll in slot rolling 31；Two connecting rod 61 head ends are provided with rocking arm 63.Two rocking arms
63 are connected by connecting shaft 64.The connection that rocking arm 63 is swingable with connecting rod 61 head end.
Two rocking arm 63 front ends are connected with fore shell 11 left and right sides wall respectively.
On rear side of vehicle frame, also protrude out a connection piece 11a in fore shell 11, be used for and turn to driving
Assembly 20 connects.
The concrete structure that turn to drive assembly of of the present invention electric pallet truck is explained in detail below.
Refer to Fig. 3-Fig. 5, electric pallet truck turn to drive assembly, it include drive
Wheel assembly 100, cylinder component 200, support holder assembly 300 and turning handle holder assembly
400.Cylinder component 200 is fixing with drive wheel assemblies 100 to be connected, turning handle holder assembly
400 fixing with cylinder component 200 are connected, and cylinder component 200 can be at support holder assembly 300
Interior rotation.
When turning to, turning handle holder assembly 400 drives cylinder component 200 supporting seat group
Rotate in part 300 and drive drive wheel assemblies 100 to rotate thus realize turning function.
Drive wheel assemblies 100 includes driving wheel 110 and drives motor 120.This enforcement
In example, drive motor 120 to be arranged at above driving wheel 110, and tied by gear drive
Power is transferred to driving wheel by structure 130.When driving motor 120 to power on, can drive
Driving wheel 110 moves, and drives motor 120 rotating i.e. to make fortune before and after driving wheel 110
Dynamic.
Driving motor 120 is arranged at above driving wheel 110, not only increases driving electricity
The terrain clearance of machine 120, reduces the little granule foreigns such as dust and enters in driving motor 120
The probability in portion, has ensured the reliability driving motor 120 work；Be also convenient for safeguard and more
Change.
Cylinder component 200 include cylinder body 210 and can in cylinder body 210 stretching motion
Plunger 220.Plunger head is provided with oil pipe connector 221 and link slot 222.
Oil pipe connector 221 is by oil pipe 223 with hydraulic oil integrated assembly 40 liquid even
Logical；Link slot 222 is connected by axle 224 is fixing with connector 11a.When hydraulic oil collection
When becoming assembly 40 to be passed through pressure oil in oil cylinder so that plunger 220 stretches out and then band motor-car
Frame rises, and when pressure oil refluxes, because vehicle frame is conducted oneself with dignity, plunger is automatically retracted thus realized
Electric pallet truck declines.
The axial line of cylinder component overlaps so that cylinder component upper end with driving wheel axial line
External force is transferred directly to drive wheel assemblies, and does not produce extra moment of flexure.
In the present embodiment, solid with driving motor 120 top by bolt bottom cylinder body 210
Fixed connection.
Support holder assembly 300 include annulus 310 and extend from annulus both sides
And two support arms 320 gone out.During installation, annulus 310 is set in cylinder block 210
Lower outside, two support arms 320 are divided into drive wheel assemblies both sides.
Owing to annulus 310 is set in cylinder block 210 lower outside, therefore annular
The height of sleeve pipe self does not interferes with electric pallet truck and drives the whole height of steering mechanism.
For making cylinder block 210 to rotate in annulus 310, at cylinder block
And also it is arranged with bearing assembly and back-up ring between annulus.Concrete, bearing assembly
Including deep groove ball bearing 330 setting up and down and be arranged between two deep groove ball bearings
Single direction thrust ball bearing 340；Back-up ring 350 is also disposed between two deep groove ball bearings.
Dust cap 360 it is additionally provided with to prevent dust from falling into bearing on the upside of upper deep groove ball bearing
Interior affect service life.
Two support arms 320 be outwardly and downwardly symmetrically extended from cylinder block 210 lateral wall and
Become so that support holder assembly entirety substantially in inverted U-shaped.With ground bottom two support arms 320
Face contacts thus plays a supporting role.
In a preferred embodiment, bottom two support arms, stabilizer 370 it is additionally provided with.
Make the turning efficiency of electric pallet truck more preferable by arranging stabilizer.
Concrete, two support arm 320 bottom inside arrange sleeve 321, in sleeve 321
Universal castor 322 is installed, on the upside of Universal castor 322, is arranged with bearing 323, spring
324；Stabilizer 370 is arranged on the downside of Universal castor 322.
When driving wheel is during turning to or running, and stabilizer can preferably keep
Electric pallet truck integral body balances.Vehicle body is more stable.
In a preferred embodiment, present invention additionally comprises the ring being arranged on the downside of annulus
Shape baffle plate 380.Ring baffle 380 diameter is more than annulus diameter and is slightly less than two
Gap between brace.Drive wheel assemblies can be hidden by so ring baffle 380, when from
On when looking down, drive wheel assemblies will not be immediately seen, the most more aesthetically pleasing, and
And fall in drive wheel assemblies prevented also from dust etc..
In the present embodiment, ring baffle 380 is spliced by two semi-circular baffle plates 381.
The present invention is when practical operation, by manpower turning handle holder assembly and then drive oil cylinder
Assembly and drive wheel assemblies synchronous axial system；Cylinder component is supporting the annulus of holder assembly
Interior rotation makes the whole height driving steering assembly only include cylinder block height and drive
Dynamic component height so that tray carriage entirety center of gravity declines, tray carriage turn to more steadily and
Integrated level is higher.
Specific embodiment described herein is only to present invention spirit theory for example
Bright.Those skilled in the art can be to described specific embodiment
Make various amendment or supplement or use similar mode to substitute, but without departing from
The spirit of the present invention or surmount scope defined in appended claims.
