Description

Storage goods shelf with electrically-adjusted width and height

Technical Field

The invention relates to a storage rack, in particular to a storage rack with electrically adjusted width and height.

Background

In storage facilities, shelves are storage facilities dedicated to storing goods, and have a very important position in logistics and warehouses. Because the plane storage occupies a large area, the volume ratio is small, the storage area is greatly limited, the storage space can be saved by the goods shelf, and the goods can be well-regulated so as to be convenient for management, therefore, modern storage enterprises need to use the goods shelf with higher width on a large scale to store the goods.

With the rapid development of modern industry, the object flow is greatly increased, so that the number of the goods shelves is increased, the goods shelves are required to have multiple functions to meet the placement of different articles, and higher requirements are put forward on the automation and mechanization of the goods shelves. In the existing goods shelf, the shelf is fixed on the upright post, the width and the layer height are fixed, but the sizes of goods are different, so that the space utilization rate of the goods shelf is not high, and a lot of waste exists. In general, the following disadvantages of the existing fixed type goods shelf are common:

(1) because the width of the storage shelf is fixed, the storage and loading and unloading efficiency of goods can be influenced when the storage shelf is not matched with the width of the goods;

(2) because the height of the storage shelf is fixed, some goods with super high height cannot be stored, the use flexibility is poor, and the uniform storage and management of the goods are inconvenient;

(3) different sizes of goods are placed in the same storage, different types of goods shelves with different widths and heights can be purchased, the regularity of the goods shelves with different types in the same storage is generally poor, the effective space of the storage cannot be better utilized, and great influence is also caused on the loading and unloading of the goods.

In order to solve the problems of the fixed shelf, some adjustable shelves are available in the prior art, such as chinese patent application No. 201710238572.7, published as 2017, 6 and 20, and the name of the invention creation is: the utility model provides a storage goods shelves with adjustable width, this application relates to a storage goods shelves with adjustable width, comprising a frame body, the support body upper end is provided with the roof, the lower extreme is provided with the bottom plate with roof parallel symmetry, the connecting plate of connecting roof and bottom plate about being provided with on the support body, the opposite face of connecting plate all is provided with horizontal evenly distributed's draw-in groove, it all is provided with the slot hole with draw-in groove phase-match end to lie in being provided with in the draw-in groove of same horizontal plane on two connecting plates, the connecting block is fixed a position with the slot hole phase-match. The storage goods shelves width of this patent application is adjustable, but the regulative mode adopts manual control, and need change the backup pad that corresponds the width after adjusting the width, need be equipped with the backup pad of different widths, and the practicality is relatively poor.

For another example, the Chinese patent number ZL201920143120.5, the publication date of the authorization is 2019, 11 and 22 months, and the name of the invention creation is as follows: the application relates to an adjustable multi-layer goods shelf, which comprises a shelf body, wherein a plurality of shelves are arranged in the shelf body at intervals, racks are also vertically arranged on the shelf body, gears are rotatably connected to the shelves, and the shelves are movably arranged in the shelf body through the meshing of the gears and the racks; the shelf is also provided with a fixing piece for limiting the rotation of the gear. The adjustable multi-layer shelf of the application can timely adjust the height between every two layers of shelves according to the volume of placed articles, so that the storage space is fully utilized. However, the height adjustment is realized by manually rotating the knobs to drive the gears to ascend and descend on the racks, four knobs are required to basically keep synchronous rotation, the adjustment operation is relatively complex, and the height adjustment efficiency is low.

In addition, a storage shelf capable of simultaneously realizing width adjustment and height adjustment of the shelf is not found at present.
