Parallel to the ground all the time in uphill process for plane on the pallet fork that guarantees goods shelf assembly 305, adopt connecting rod mechanism: first connecting rod seat 309 is fixed on the plane, bottom of vehicle frame 301, and first connecting rod seat 309 is hinged through primary shaft 310 with first connecting rod 311; First connecting rod 311 and the one or three connecting rod 313 first jiao is hinged through second 312; Second connecting rod seat 314 is fixed on the trailing flank bottom of goods shelf assembly 305, and second jiao of the one or three connecting rod 313 is hinged through third axle 315 and second connecting rod seat 314; The triangle of the one or three connecting rod 313 is hinged through an end of the 4th 316 and one push rod 317, and push rod 317 is parallel to the below that pallet fork is arranged on pallet fork; Hinged between first jiao of the other end of push rod 317 and one the 23 connecting rod 319 through the 5th 318; Second jiao of the two or three connecting rod 319 and crotch are hinged through the 6th 320 between the bottom foremost; The pallet fork of said goods shelf assembly 305 bottom foremost also is equipped with preceding BOGEY WHEEL assembly 322; Hinged between the triangle of the two or three connecting rod 319 and the preceding BOGEY WHEEL assembly 322 through the 7th 321; Wherein, the 6th 320 between the 5th 318 and the 7th 321.
When piston rod 308 rises; Goods shelf assembly 305 rises; The second connecting rod seat 314 that drive is fixed on the goods shelf assembly 305 rises; Second connecting rod seat 314 promotes connecting rods 311 through the one or three connecting rod 313 and rotates around primary shaft 310, connecting rod 311 and then to drive the one or three connecting rod 313 be that circular motion is done in the center of circle with primary shaft 310; It is that circular motion is done in the center of circle with second 312 that the one or three connecting rod 313 drives second connecting rod seat 314 simultaneously through third axle 315; It is that circular motion is done in the center of circle with the 4th 316 that the one or three connecting rod 313 drives push rod 317 through the 6th 316; It is that circular motion is done in the center of circle with the 6th 320 that push rod 317 drives the two or three connecting rod 319 simultaneously through the 5th 318; Because the 6th 320 is fixed on the goods shelf assembly 305; Forcing the two or three connecting rod 319 is that the center of circle downwards do circular motion with preceding BOGEY WHEEL assembly 322 with the 6th 320 through the 7th 321, thereby preceding BOGEY WHEEL assembly 322 is propped up goods shelf assembly 305 levels.
The purpose of design connecting rod 311 is to solve roller 306 to receive channel-section steel 303 constraints can only do perpendicular movement up and down, and the one or three connecting rod 313 is done circular motion and the interference that produces.This structure guarantees goods shelf assembly 305 up-and-down movement maintenance levels fully.Overcome the problem that other electronic tray carriage pallet forks can not the maintenance level when up-and-down movement.
Can the screw thread rigidity external many on the vehicle frame 301 with electronic control traction drive head connection supporting seat 1 to outside link plate 302, be combined into all-electric tray carriage shown in Figure 9.
The 3rd application implementation example:
See also Figure 12, for adopting the many flat carrier constructionals drawing of the present invention with electronic control traction drive head.How the present invention mixes the flat carrier car body with electronic control traction drive head is promptly formed driven plate transport trolley car.Please consult Figure 13 simultaneously, be the spatial structure view of driven plate transport trolley car body.
This driven plate transport trolley car body 40 comprises vehicle frame 401, preceding BOGEY WHEEL 402,403,4 bolts 404 of the universal auxiliary wheel in back, battery pack 405, and battery socket and cable 406.
Wherein the plane is made in vehicle frame 401 anterior upper surfaces, and as trucking department, preceding BOGEY WHEEL 402 has two; Be installed in the both sides of vehicle frame 401 anterior bottoms respectively; The universal auxiliary wheel 403 in back also has two, is installed in the both sides of bottom, vehicle frame 401 rear portion respectively, and battery pack 405 also is fixedly mounted on the vehicle frame 401; In the present embodiment; Battery pack 405 also is fixedly mounted on the top at vehicle frame 401 rear portions, and battery socket and cable 406 are installed on vehicle frame 401 aft end faces, and battery socket and cable 406 are electrically connected with battery pack 405.In addition, offer four screws (figure indicates) on vehicle frame 401 aft end faces, four screws are arranged in rectangular shape, in 4 bolt 404 these four screws of difference precession.Use this 4 bolts 404, be that with how supporting seat 1 screw threads that are connected with electronic control traction drive head are rigidly connected in order to make this driven plate transport trolley car body 40, thereby form all-electric flat carrier shown in figure 12.
Universal auxiliary wheel 403 and two preceding BOGEY WHEELs 402 are not on same horizontal surface after two; When the level of the upper surface of vehicle frame 401 front portions; The bottom face 5mm of BOGEY WHEEL 402 before the bottom face of the universal auxiliary wheel 403 in back exceeds; To guarantee that many drive wheels 3 with electronic control traction drive head contact with ground all the time, produce enough propulsive efforts.403 of the universal auxiliary wheels in back play the supplemental support effect.
Though more than described the specific embodiment of the present invention; But the technical personnel of being familiar with the present technique field is to be understood that; We described concrete embodiment is illustrative; Rather than being used for qualification to scope of the present invention, those of ordinary skill in the art are in the modification and the variation of the equivalence of doing according to spirit of the present invention, all should be encompassed in the scope that claim of the present invention protects.
