Specific implementation mode
Shown in Fig. 1, the utility model discloses a kind of automatic reverse walking dolly, is applied in storage rack.It should
The upper body 1 that walking dolly includes lower body 2, is carried on lower body 2, the jacking dress between upper body 1 and lower body 2
It sets.The two sides of the upper body 1 are equipped with first group of wheel 11；The both ends of the surface of lower body 2 are equipped with second group of wheel 21.This
In " side " and " end face " be to clearly show spatial relationship, i.e., the direction of travel and second group of vehicle of first group wheel 11
The direction of travel of wheel 21 is orthogonal.It is corresponding, the rotation axis 22 of the rotation axis 12 of first group of wheel 11 and second group of wheel 21
Vertically.The body of rod 6 tiltedly protruded outward is additionally provided on four corners of the lower body 2, the outer end of the body of rod 6 is equipped with guide wheel 61
To correct direction of travel in time in carriage walking.
The jacking apparatus includes the active runner 31 being mounted on upper body 1, drives the runner of 31 rotation of active runner
Motor 311.The active runner 31 outwardly protrudes out the first eccentric shaft 32；The lower body 2, which is equipped with, to be laterally arranged
Waist-shaped hole 23.First eccentric shaft 32 is inserted into the waist-shaped hole 23.In the present embodiment, for the processing side of waist-shaped hole
Just, which is trepanning on a waist type disk 24, is assembled again after processing waist-shaped hole 23 on the waist type disk 24
It is fixed on lower body 2.
In the case where the rotation of runner motor drives, the active runner 31 rotates between first position and the second position, so that
Upper body 1 increases or declines relative to lower body 2.
Shown in Fig. 3 and Fig. 5, when active runner 31 is located at first position, the bottom of first group of wheel is low
In the bottom of second group of wheel；That is first group of wheel 11 lands and second group of wheel 21 is hanging, at this point, walking dolly is by first group
The driving walking of wheel 11, direction of travel is also the direction of travel of first group of wheel 11.
Shown in Fig. 4 and Fig. 6, when the active runner 31 turns to the second position, the first eccentric shaft 32 is located at
31 lower section of active runner, upper body 1 are increased relative to 2 position of lower body, and the bottom of first group of wheel 11 is higher than second group
The bottom of wheel 21；That is first group of wheel 11 is hanging and second group of wheel 21 lands, at this point, walking dolly is by second group of wheel 21
Driving walking, direction of travel is also the direction of travel of second group of wheel 21.
According to aforementioned, the direction of travel of first group of wheel 11 and second group of wheel 21 is mutually perpendicular, therefore by above-mentioned
Structure can make walking dolly commutate automatically, and the crossing on track especially in storage rack is the commutation of vertical direction,
Therefore the walking dolly can run to any position on shelf.The first above-mentioned eccentric shaft 32 rolls in waist-shaped hole, will revolve
Transhipment is dynamic to become horizontal linear motion, when active runner 31 rotates 180 °, reaches range, i.e. 32 liang of the first eccentric shaft
Eccentricity again.In addition, upper body and loading portion are individually taken out the trolley that can also become one-way traffic by the trolley, answer
For simple storage environment, the versatility of the walking dolly is improved.
And in a further embodiment, in order to make jacking apparatus more stablize the lift action of upper body 1,
The walking dolly further includes the driven runner 33 being arranged side by side with active runner 31, and the driven runner 33 is equal with active runner 31
With external tooth, active runner 31 is driven by rack 34 or chain (chain can replace figure middle rack, not shown) from turn
Wheel 33 rotates simultaneously, and the driven runner 33 is equipped with the second eccentric shaft 35, and also is provided on lower body 2 and the second eccentric shaft 35
The waist-shaped hole of cooperation.When the active runner 31 is rotated with driven runner 33, the height of the first eccentric shaft 32 and the second eccentric shaft 35
Degree is consistent always.It drives upper body 1 to move simultaneously by two runners, the mobile stabilization of upper body 1 can be kept, reduced to upper
The influence of bearing goods on car body 1.And the driving of driven runner 33 is conducted by active runner 31, does not need to reconnect
Motor occupies inner space.And due between active runner 31 and driven runner 33 distance machining ensure precision it is too high, in order to
Machining accuracy is reduced to be set as the structure of rack 34：The rack 34 include first segmentation 341, second segmentation 342 and
The screw rod 343 of connection the first segmentation 341 and the second segmentation 342.The lower section of first segmentation, 341 and second segmentation 342 is equipped with
Tooth, and the first segmentation 341 is engaged with active runner 31, the second segmentation 342 is engaged with driven runner 33.Two segmentations are adjusted when assembly
Distance makes rack be snapped at active runner 31 and driven runner 33.Further, it is two that the jacking apparatus, which can be arranged, and
The both ends of the surface of upper body 1 are symmetrically located in, two jacking apparatus drive upper body 1 to move, make the stress of upper body 1 more simultaneously
Balance, further increases integrally-built stability.
Please in conjunction with shown in Fig. 7 and Fig. 8, upper and lower point will produce since active runner 31 drives the first eccentric shaft 32 to rotate
The lateral component in power and vertically direction, upper and lower component instead can for lateral component for the jacking commutation of upper body 1
Cause upper body 1 to be moved in the horizontal relative to lower body 2, and preferably upper body 1 relative to lower body 2 in transverse direction
On need not move to ensure stability.Therefore further include guider 4 in the walking dolly, the guider 4 includes installation
On lower body 2 and the guide rod 41 upwardly extended and the linear bearing 42 on upper body 1, the guide rod 41
It is plugged in linear bearing 42.Therefore transverse component is finally transformed into straight line when active runner 31 drives the rotation of the first eccentric shaft 32
Friction between bearing 42 and guide rod 41 makes upper body 1 not moved in the horizontal relative to lower body 2.
Please in conjunction with shown in Fig. 7 and Fig. 9, first group of wheel 11 includes two the first driving wheels 111 and two
One driven wheel 112；Second group of wheel 21 includes two the second driving wheels 211 and two the second driven wheels 212.Described two
It is equipped with first motor 51 between one driving wheel 111 and drives the first driving wheel, is equipped with and drives between described two second driving wheels 212
Second motor 52 of dynamic second driving wheel.The centre position of the upper body 1 is set as loading area 14, the both sides in the loading area 14
Equipped with flexible goods taking device 15, the first motor 51 and the second motor 52 are located at the both sides in loading area 14.In this implementation
The diameter of first driving wheel 111 and the first driven wheel 112 described in mode is identical, the second driving wheel 211 and the second driven wheel 212
Diameter it is identical, and the diameter of the first driving wheel 111 be more than the second driving wheel 211 diameter.Accordingly even when due to upper body 1
In the case of the higher central point for causing the first driving wheel 111 is set compared with 212 central point height of the second driving wheel, due to the first driving wheel
111 and first driven wheel 112 diameter it is big, the first driving wheel 111 and the first driven wheel 112 can be made to be remained at first position
Enough realize that bottom is less than the effect of the second driving wheel 211.
The utility model implement the technical solution method and approach it is very much, the above is only the utility model
Preferred embodiment.It should be pointed out that for those skilled in the art, not departing from the utility model principle
Under the premise of, several improvements and modifications can also be made, these improvements and modifications also should be regarded as the scope of protection of the utility model.
All undefined components in this embodiment can be implemented in the prior art.
