Interior side is provided with chute, and chute is C-shaped, for coordinating with the upper skid of row's roller 1224 on middle fork 122 and guiding, simultaneously
The bottom land of chute is used to slide with the guide pad 1225 on middle fork 122 and block coordinates, to prevent upper fork 121 relative to middle fork 122
It is crooked.Top plate 1212 and two blocks of upper fork side plates 1213 can be bolted fixed or integral material and be process.
As shown in fig. 7, lower fork 123 includes bottom plate 1232 and the lower fork side plate 1233 positioned at both sides, bottom plate 1232 is with
Fork side plate 1233 surrounds groove structure, and lower fork rack 1231 is provided with the bottom plate in groove structure, for middle prong wheel
1222 engaged transmissions simultaneously provide opposition with fork 122 in realizing relative to the relative shiftings of lower fork 123 for middle prong wheel 1222
It is dynamic.The relative side of lower fork side plate 1233, i.e., the side in groove structure are provided with chute, and chute is C-shaped, for middle fork
The lower skid of row's roller 1224 and guiding on 122 coordinate, while the bottom land of chute is used to slide with the guide pad 1225 on middle fork 122
Dynamic and block coordinates, crooked relative to lower fork 123 to prevent middle fork 122.Bottom plate and two blocks of lower fork side plates 1233 can pass through bolt
It is connected or is process using integral material.Being additionally provided with bottom plate inside the groove structure of lower fork 123 prevents middle fork
122 limited blocks 1235 slipped from lower fork 123, limited block 1235 are arranged on the position at the close both ends of lower fork 123.Lower fork
The position of drive gear 124 is additionally provided with resigning hole 1234 when corresponding assemble on 123 bottom plate, so that drive gear 124 passes through
Bottom plate and the middle engaged transmission of prong bar 1221 in groove structure.
As shown in figure 3, after the outputting axial power of rotating reducing motor 14 passes to universal drive shaft 13, the two of universal drive shaft 13
End is rotated by the drive gear 124 being connected with driving gear 18 to drive with driving gear 18 engages respectively, i.e., two
Drive gear 124 engages positioned at the both sides of driving gear 18 and with driving gear 18 simultaneously respectively.Pass through drive gear 124 and middle fork
The driving of centering fork 122 is realized in the cooperation of rack 1221, and which has precision high, no relative to traditional chain sprocket mode
The characteristics of being influenceed by slack list pilled-in selvedge, for the type of drive of traditional feed screw nut, gear is in 122 moving directions of middle fork
On space hold it is significantly smaller, be easy to implement the way moving of middle fork 122, and traditional feed screw nut type of drive is by leading screw
Length limitation and the requirement of pallet fork extension elongation, can not typically realize bi-directional expansion, generally unilateral one-way expansion, limit significantly
Its application.Electrical control unit 17 is additionally provided with upper fork, lower fork bottom is provided with transmission case, above-mentioned driving gear, driven
Moving gear is located in transmission case.
The production line of the present embodiment is when in use：Need to realize that the goods handing-over in two goods yards of two-way transfer pallet fork 1 turns
During shifting, control rotating reducing motor 14 to rotate by controller first, drive universal drive shaft 13 to rotate, while drive two pallet fork lists
The driving gear 18 of member 12 rotates, and driving gear 18 drives two drive gears 124 being engaged with synchronously to rotate in same direction, so as to
Drive the middle prong bar 1221 being engaged with to move, i.e., it is middle to pitch 122 to stretching at the goods yard for loading goods, the movement of middle fork 122
Drive middle prong wheel 1222 thereon to rotate, and then drive the upper prong bar 1211 being engaged with to move, i.e., upper fork 121 can be relative
Stretched out in middle fork 122, because upper fork 121 is on middle fork 122, itself can be with the middle movement of fork 122, the knot of two speed superpositions
Fruit is that upper fork 121 is stretched out with the speed of twice middle fork 122, so as to realize high efficiency stretching motion, is treated when upper fork 121 is moved to
Controlled motor stalls during the lower section of transfer goods, coordinates lift to depart from goods jack-up and corresponding carrier, goods is ascended the throne
In on upper fork 121；Control rotating reducing motor 14 is inverted, and 121 are pitched in same driving process control and is withdrawn rapidly, upper fork
121 continue to drive rotating reducing motor 14 to rotate when being retracted to original centre position, and now upper fork 121 starts to opposite side
Stretch out, until controlling rotating reducing motor 14 to stall when reaching above the goods yard of opposite side, then coordinate lift by goods
Thing is dropped down onto on the carrier in this goods yard, then controls rotating reducing motor 14 to invert again so that upper fork 121, middle fork 122 to be withdrawn i.e.
Can.
Embodiment 2：It is with the difference of embodiment 1, as illustrated in figs. 8-12, in the upper fork side plate 1213 of upper fork 121
Relative side sets row's roller 20, and the chute 21 being adapted to therewith is correspondingly set on the outside of two external support boards of middle fork 122,
Both are oriented to and are slidably matched.
Embodiment 3：It is with the difference of embodiment 1, as shown in figure 13, the both sides of driving gear engage two simultaneously
Drive gear, i.e. first pair of drive gear；A pair of commutation travelling gears 30 are engaged in the outside of first pair of drive gear, this is a pair
Second pair of drive gear is engaged in the outside of commutation travelling gear 30 respectively, and commutation travelling gear 30 can be by first pair of drive gear
Power passes to second pair of drive gear, and realizes commutation, it is ensured that and the direction of rotation of four drive gears is consistent and rotation is synchronous,
Four drive gears engage with middle prong bar 1221 simultaneously, and this set-up mode can increase the length of action with middle prong bar 1221,
So as to the extension elongation of fork 122 in extending.
In other embodiments：One pallet fork unit also can be only set, while set one again only to have upper, middle and lower fork
And drive mechanism and the Auxiliary support fork of sliding matching structure between them, the Auxiliary support, which is pitched, does not have drive gear and master
Moving gear etc., simply by the Auxiliary support for being connected with another pallet fork unit and being moved with pallet fork unit；Two pallet fork units
Also can be linked together by connecting rod or connecting plate etc., another is servo-actuated when driving one of mobile；The quantity of middle prong wheel
Two are also not necessarily limited to, also can be replaced three, four etc., transmission knot is correspondingly set between any two neighboring middle prong wheel
Structure, so as to ensure each middle prong wheel synchronous axial system, still may be used even if such benefit is middle prong wheel with the disengaging of lower fork rack
To impart power to prong wheel in this by the middle prong wheel still engaged with lower fork rack；The quantity of transmission idle pulley can also be replaced
The odd number such as one, three or seven is changed to, odd number can ensure that the middle fork pinion rotation direction of both sides is identical；It is driven idle pulley
Also can be assemblied in by needle bearing on two external support boards；Roller also can be replaced sliding block；Drive gear is also not necessarily limited to implement
Two of example 1 and five of embodiment 3, a drive gear also can be only set, driving gear is now no longer set, will directly driven
Moving gear and universal axis connection；It may also set up two rotating reducing motors, the output shaft difference of two rotating reducing motors
It is driven and coordinates with the driving gear of two pallet fork units, then by ensuring two to two rotating reducing motor homogenous frequency signals
Individual motor synchronization action；Also can be arranged on by double output shaft electric machines between two pallet fork units, two outputs of double output shaft electric machines
Axle is connected with the driving gear of two pallet fork units respectively.
The embodiment of the two-way transfer pallet fork of the present invention and the two-way transfer goods in each embodiment of the production line of the present invention
Each embodiment of fork is identical, repeats no more.
