Description

For a warehouse with large area, the installation position of the lifter provided by the utility

model may not be limited.

The goods lifting system in the present embodiment adopts the telescopic fork carrying

platform 5 to pick and place goods. The shelf body 6 is provided with the transferring table

which plays a role in temporarily storing the material box 8. This structure substitutes a structure

in which each storage layer is provided with a roller line, and a roller-type carrying platform is

docked with the roller line, which can save the cost significantly and improve the operation

reliability for a high-rise warehouse. In addition, the telescopic fork carrying platform 5 is

directly docked with the shelf body 6, and the lifter can be arranged inside the shelf body 6

without being limited to the end of the shelf body 6, so that the layout flexibility of a warehouse

system can be improved. Moreover, for the warehouse with long passages, a plurality of lifters

may be arranged in one passage, so that the efficiency of transferring the material box 8 to

another layer is apparently increased. Furthermore, the telescopic fork carrying platform 5 adopts

a centering clamping form, which is suitable for the material box 8 of different sizes and keeps

the center position of the material box 8 unchanged.

In the present embodiment, the shelf body 6 includes two groups of vertical supporting

assemblies which are parallel to each other and are spaced. Each group of vertical supporting

assemblies includes at least two vertical beams 63 which are spaced and are parallel to each

63. The transferring table includes at least two crossbeams 62 which are spaced. The crossbeams

62 and the supporting beams 61 are connected with each other perpendicularly within a same

plane. When goods are picked, a shuttle trolley first places the material box 8 onto the

crossbeams 62, and then the telescopic fork carrying platform 5 of the lifter can extend out to

pick the material box 8 from the crossbeams 62; and when the goods are placed by the lifter, the

telescopic fork carrying platform 5 of the lifter first places the material box 8 onto the

crossbeams 62, and then the shuttle trolley picks the material box 8. The transferring table

Description

provided by the present embodiment is simple in structure and low in use cost, and substitutes

the traditional structure of a roller line. In other embodiments, the transferring table may also be

other structures, which is not limited here.

Referring to Fig. 3 and Fig. 4, the lifting guide mechanism 1 includes an even number of

guide rails 11 which are arranged symmetrically and top plates 3 and bottom plates 7 which are

connected to two ends of the guide rails 11. The top plates 3 are fixed on the shelf body 6. The

bottom plates 7 are connected with the ground. Two adjacent guide rails 11 are connected through a connecting assembly 12. Each guide rail 11 is made of aluminum alloy sectional bars

with an L-shaped section. Each guide rail 11 is provided with an installation surface 112 for

surface and the third guide surface are parallel to each other. The first guide surface and the third

guide surface are perpendicular to the second guide surface respectively, thereby improving the

rising and falling stability of the lifting frame mechanism 2. The bottom plates 7 are connected

with the ground through bolts. The levelness of the bottom plates 7 can be adjusted by screwing

the bolts. Furthermore, each guide rail 11 is made of aluminum alloy sectional bars which

substitute steel columns in the prior art. The surface smoothness of the aluminum alloy sectional

bars is relatively high, so that the surface of the aluminum alloy sectional bar can be directly

used as the guide surface without additional machining, thereby reducing the production cost.

The aluminum sectional bars can be spliced to form the guide rail 11 of any height, so that the

aluminum alloy sectional bar is suitable for the high-rise warehouse, and the assembling

requirement is low. Furthermore, the aluminum alloy sectional bar is light in weight and

applicable to the lifter of the high-rise warehouse, thereby lowering the requirement for the civil

construction and ground bearing capacity.
