Description

Three-section type pallet taking fork

Technical Field

The utility model belongs to the technical field of the warehouse system, especially as the expansion plate fork that the goods was carried.

Background

In the existing conveying equipment (such as an AGV (automatic guided vehicle)) of the storage system, a container bracket which can stretch to one side of a frame is often adopted to carry out the picking and placing operation of a container. For example, chinese patent application publication No. 110606317a discloses a removable pallet fork including a frame, a center pallet disposed on the frame, and an upper pallet disposed on the center pallet. The center pallet moves relative to the frame and the top pallet moves relative to the center pallet to further increase the overall pallet reach. Frame thickness in this patent application is great, and the cooperation mode occupation space of the driving chain that adopts and rack on the frame is big, causes overall structure to be difficult to use in miniature AGV dolly.

This type of pallet fork is widely available in the prior art. In practice, it has been found that these pallet forks generally comprise two structural materials: one is that all fork bodies are steel material, and this kind of structural advantage is structural strength height, and it is little to stretch out to wind under the back fork body. The defect is that the weight is heavy, and the requirements on the structural strength of a motor reducer, a guide wheel and the like are high. The other main structure is that all fork bodies are made of aluminum materials, and the structure has the advantages of light weight, low strength requirements of a motor speed reducer, a guide wheel and the like, and the defect that after the fork bodies are stretched out, the fork bodies are wound downwards greatly, so that goods are prone to slipping and damage.

Therefore, a new technical solution is needed to solve the above problems.

Detailed Description

As shown in fig. 1 and fig. 2, the utility model discloses a syllogic pallet fork, including flat fork 1, the well fork 2 of setting on fork 1, the last fork 3 of setting on well fork 2. The bottom of the lower fork 1 is provided with a motor 4, a synchronous belt driving wheel 5 driven by the motor 4 and a double-sided tooth synchronous belt 6 driven by the synchronous belt driving wheel 5. The lower surface of the middle fork 2 is provided with a lengthwise toothed plate 7, and the double-sided toothed synchronous belt 6 is meshed with the toothed plate 7 and drives the middle fork 2 to extend or retract relative to the lower fork 1 through positive rotation or negative rotation of the motor 4. The middle fork 2 is provided with a pulley groove, and a fork extending synchronous belt idler wheel 8 is arranged in the pulley groove. Should stretch and to have on the fork hold-in range idler 8 to stretch and to have fork hold-in range 9, and stretch the one end of fork hold-in range 9 and fix at 3 lower surfaces of upper forks, the other end of stretching fork hold-in range 9 is fixed at 1 upper surface of lower fork. When well fork 2 stretches out for lower fork 1, the part that is located the fork hold-in range 9 that stretches of well fork 2 below is lengthened, then the part that is located the fork hold-in range 9 that stretches of well fork 2 top is shortened, makes the fixed position of upper fork 3 and fork hold-in range 9 to stretching fork hold-in range idler 8 and remove to it stretches out for well fork 2 to drive upper fork 3. While, on the same principle, when the middle fork 2 is retracted relative to the lower fork 1, the upper fork 3 is also retracted relative to the middle fork 2. The two ends of the fork extending synchronous belt 9 are fixed on the lower surface of the upper fork and the upper surface of the lower fork through synchronous belt clamping plates 16.

The two side surfaces of the lower fork 2 are provided with a plurality of inner guide wheels 10 which are arranged along the longitudinal extension direction of the lower fork. Two sides of the bottom surface of the middle fork 2 are respectively provided with a guide groove plate 11. Two vertical ribs 12 extending along the longitudinal extension direction of the upper fork 3 are respectively arranged on two sides of the bottom surface of the upper fork 3. And a plurality of outer guide wheels 14 arranged along the longitudinal extension direction of the upper fork 3 are arranged on the inner side of the stud 12. An inner guide groove is arranged on the inner side of the guide groove plate 11 of the middle fork 2, and an outer guide groove is arranged on the outer side of the guide groove plate 11. The inner guide wheel 10 is located in the inner guide groove and the outer guide wheel 14 is located in the outer guide groove. The upper surface of the middle fork 2 is provided with a plurality of threaded holes and is fixed with the guide groove plate 11 through screws penetrating through the threaded holes.
