Description

A storage rack with electric width and height adjustment

technical field

The present invention relates to a rack, more particularly, to a storage rack with electric width and height adjustment.

Background technique

In warehousing equipment, shelves are storage facilities specially used to store goods, and occupy a very important position in logistics and warehouses. Due to the large area of plane storage, the small volume ratio, and the limited warehouse area, the shelf can not only save storage space, but also make the goods organized and easy to manage. Therefore, modern storage companies need to use large-scale High and wide shelves to store goods.

With the rapid development of modern industry and the substantial increase in logistics flow, not only the number of shelves is required to increase, but also the shelves are required to have multiple functions to meet the placement of different items, which puts forward higher requirements for the automation and mechanization of shelves. In the existing shelf, the shelf is fixed on the column, the width and height are fixed, but the volume of the goods is different, which leads to the low space utilization rate of the shelf, and there is a lot of waste. . In general, the existing fixed shelves generally have the following shortcomings:

(1) Due to the fixed width of the storage shelf, when it does not match the width of the goods, it will affect the storage and loading and unloading efficiency of the goods;

(2) Due to the fixed height of the storage shelves, some super-high goods cannot be stored, and the flexibility of use is poor, which is not convenient for the unified storage and management of goods;

(3) When placing goods of different sizes in the same warehouse, it will be necessary to purchase different types of shelves with different widths and heights, and these different types of shelves are generally less regular in the same warehouse, and cannot make better use of the effective storage space. The loading and unloading of goods also has a greater impact.

In order to solve the problems of the above-mentioned fixed shelves, there are also some adjustable shelves in the prior art, such as the Chinese patent application number 201710238572.7, the application publication date is June 20, 2017, and the name of the invention is: an adjustable width Storage rack, the application relates to a storage rack with adjustable width, including a rack body, the upper end of the rack body is provided with a top plate, the lower end is provided with a bottom plate that is parallel and symmetrical with the top plate, and the rack body is provided with upper and lower connecting plates connecting the top plate and the bottom plate The opposite sides of the connecting plate are provided with horizontally evenly distributed card slots, and the card slots on the two connecting plates located on the same horizontal plane are provided with long holes at the matching ends of the card slots. Positioned by positioning bolts, the connecting block can slide laterally along the long hole. The width of the storage shelf in this patent application can be adjusted, but the adjustment method is manually controlled, and the support plate of the corresponding width needs to be replaced after the width is adjusted, and the support plate of different width needs to be equipped, which is less practical.

Another example is the Chinese patent number ZL201920143120.5, the authorization announcement date is November 22, 2019, and the name of the invention is: an adjustable multi-layer shelf. The application involves an adjustable multi-layer shelf, including a shelf body A plurality of shelves are arranged at intervals in the frame body, racks are also arranged vertically on the frame body, gears are rotatably connected to the shelves, and the shelves are movably arranged in the frame body through the meshing of the gears and the racks; the shelves are also provided with A fixing that restricts the rotation of the gear. The adjustable multi-layer shelf of the application can timely adjust the height between each layer of shelves according to the volume of the items to be placed, so as to make full use of the storage space. However, its height adjustment is achieved by manually rotating the knob to drive the gear to rise and fall on the rack, requiring four knobs to basically keep rotating synchronously, the adjustment operation is relatively cumbersome, and the height adjustment efficiency is low.

In addition, a storage shelf that can realize both the width adjustment and the height adjustment of the shelf has not yet been found.

When the width is adjusted, the bottom scissor adjusting electric push rod 43 of the bottom scissor width adjusting mechanism 4 and the top scissor adjusting electric push rod 63 of the top scissor width adjusting mechanism 6 work synchronously. When the angle of the rod assembly changes, the bottom scissor width adjusting mechanism 4 and the top scissor width adjusting mechanism 6 synchronously drive the bottom shelf space 7 and the top shelf space 9 to carry out telescopic adjustment in the width direction, thereby further driving the middle shelf space 8 to change the shelf together. Width dimension, at this time, the bottom shelf space 7 and the top shelf space 9 will also change in height direction at the same time, that is, the larger the width of the bottom shelf space 7 and the top shelf space 9, the shorter the corresponding height, and the bottom shelf space The smaller the width 7 and the top shelf space 9, the correspondingly higher height. When the height of the middle shelf space 8 is adjusted, the middle scissor adjustment electric push rod 53 of the corresponding scissor height adjustment mechanism 5 works, and the corresponding middle shelf space 8 is adjusted by the lifting movement of the X-shaped link assembly.
