Description
Technical field
The utility model relates to a kind of pallet fork jacking system, is specially a kind of pallet fork jacking system that is used on the electric pallet truck.
Background technology
At present, in the prior electric tray truck, all pallet fork jacking systems all are to lean on hydraulic actuating cylinder compressing connecting rod mechanism to promote push rod; Make front wheel carrier along the anterior axle center rotation of push rod; Thereby produce the up-down that diff-H is realized pallet fork, this lifting structure comprises preceding wheel assembly, front wheel carrier, push rod, push arm, pallet fork, goods shelf, connecting rod, car body, and an end of front wheel carrier is rotatably connected on the preceding wheel assembly with wheel frame axle; The other end is rotatably connected on the push rod with the push rod front axle; The other end of push rod is rotatably connected on the push arm with push rod shaft, and an end of push arm is connected with goods shelf through the wheel carrier adapter shaft, and the other end is connected with the cylinder body bottom of hydraulic actuating cylinder; The free end of hydraulic actuating cylinder then is connected with the connecting rod rotating shaft; One end of connecting rod also is connected with car body through the connecting rod rotating shaft, and the bonded assembly other end also is to be connected on the goods shelf with rotating shaft, and pallet fork and goods shelf are welded as a whole.Hydraulic actuating cylinder moves to power of push arm like this, and push arm is rotated around the wheel carrier adapter shaft, drives push rod and moves forward, because wheel frame axle is fixed, just makes front wheel carrier up rotate around wheel frame axle, and the relative height of using rotation to be produced realizes the rising of pallet fork; Otherwise, then descend.But; There is following shortcoming in this structure: in the lifting process of pallet fork, pallet fork is that oil cylinder is kept in motion with the rotational trajectory of a circumferencial direction; Therefore the car load bodywork length is vicissitudinous, and this brings certain influence on the working space of electric pallet truck.
The utility model content
The utility model technical matters to be solved provides a kind of car load bodywork length unmodified electric pallet truck pallet fork jacking system.
For solving the problems of the technologies described above; A kind of electric pallet truck pallet fork of the utility model jacking system; Comprise car body, pallet fork, push rod, front wheel carrier, preceding wheel assembly, the goods shelf of captiveing joint, two ends with said pallet fork respectively with said car body and goods shelf bonded assembly hydraulic actuating cylinder, push arm; One end of said front wheel carrier is rotatably connected on the said preceding wheel assembly; The other end is rotatably connected on an end of said push rod through the push rod front axle, and said front wheel carrier is rotationally connected through wheel carrier adapter shaft and the pallet fork lower than the position of said push rod front axle, and said push arm rear end and car body are rotationally connected; First end is connected on the said goods shelf, and the other end of second end and said push rod is rotationally connected.
Preferably, first end of push arm and an end of connecting rod are rotationally connected, and the other end of said connecting rod and said goods shelf are rotationally connected.
Preferably, first end of said push arm is connected with a roller, and said roller rolls and is engaged in the positioning plate top of being located on the said goods shelf.
After adopting this structure, when goods shelf hoists, can drive push arm and rotate, promote push rod and travel forward, thereby promote the front wheel carrier rotation, realize that pallet fork hoists.Because hydraulic actuating cylinder is captiveed joint with car body, goods shelf, push-pull effort before and after can overcoming when hydraulic actuating cylinder hoists guarantees the goods shelf vertical lifting, thereby can not increase the working space of electric pallet truck.
Description of drawings
Fig. 1 is the structural representation of the utility model electric pallet truck pallet fork jacking system embodiment one;
View when Fig. 2 is the rise of Fig. 1 embodiment pallet fork;
Fig. 3 is the utility model electric pallet truck pallet fork jacking system embodiment two structural representations.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described further.The description of this part only is exemplary and explanatory, and the multitude of different ways that the utility model can be defined by the claims and cover is implemented, and any restriction should not arranged to the protection domain of the utility model.
Embodiment one illustrated in figures 1 and 2; Electric pallet truck pallet fork jacking system; Comprise car body 1, pallet fork 7, push rod 6, front wheel carrier 11, preceding wheel assembly 10, the goods shelf 3 of captiveing joint, two ends fixing or pivotally attached hydraulic actuating cylinder 2, push arm 14 with said car body 1 and goods shelf 3 respectively with said pallet fork 7; One end of said front wheel carrier 11 be rotatably connected on said before on the wheel assembly 10, the other end is rotatably connected on an end of said push rod 6 through push rod front axle 8, said front wheel carrier 11 is rotationally connected with pallet fork 7 through the wheel carrier adapter shaft 9 lower than the position of said push rod front axle 8; Said push arm 14 rear ends and car body 1 are rotationally connected; One end of first end and connecting rod 4 is rotationally connected, and the other end of second end and said push rod 6 is rotationally connected, and the other end of said connecting rod 4 and said goods shelf 3 are rotationally connected.During work; Hydraulic actuating cylinder 2 up moves; Drive goods shelf 3 upward movements, goods shelf 3 pulling connecting rods 4 upward movements, and connecting rod 4 drives push arm 14 and clockwise rotates around axle 15; Make push arm 14 promote push rod 6 through axle 13 and travel forward, this moment, front wheel carrier 11 received a thrust forward at push rod front axle 8 places.Because preceding wheel assembly 10 is fixed, the position of wheel frame axle 9 is lower than the position of push rod front axle, and therefore, front wheel carrier 11 can only force pallet fork 7 up to rise around the motion of wheel frame axle 9 toward the previous crops circumferencial direction like this.Otherwise, then descend.
Embodiment two shown in Figure 3; On the basis of embodiment one electric pallet truck pallet fork jacking system; Connecting rod 4 is replaced with roller 17, and push arm 14 rear ends are rotationally connected through push arm rear axle 15 and car body 1, and second end is rotatably connected on the push rod 6 through push rod rear axle 13; First end is connected with roller 17, and roller 17 rolls and is engaged in positioning plate 16 tops of being located on the said goods shelf 3.During work; Hydraulic actuating cylinder 2 up moves; Drive goods shelf 3 upward movements, goods shelf 3 drives rollers 17 upward movements, and roller 17 drives push arm 14 and clockwise rotates around axle 15; Make push arm 14 promote push rod 6 through axle 13 and travel forward, this moment, front wheel carrier 11 received a thrust forward at push rod front axle 8 places.Because preceding wheel assembly 10 is fixed, the position of wheel frame axle 9 is lower than the position of push rod front axle, and therefore, front wheel carrier 11 can only force pallet fork 7 up to rise around the motion of wheel frame axle 9 toward the previous crops circumferencial direction like this.Otherwise, then descend.
