Description

Multipurpose conveying box

Technical Field

The invention relates to the technical field of multipurpose conveying devices, in particular to a multipurpose conveying box.

Background

The conventional conveying device has a single conveying function, and for example, a V-shaped conveying device disclosed in publication No. CN202807616U includes a bracket, a V-shaped conveying plate, a roller bracket, and a roller mounted on the roller bracket. The V-shaped transmission plates are split and symmetrically arranged on the bracket. The V-shaped transmission plates are multiple and are symmetrically distributed along the central line of the bracket. One end of the V-shaped transmission plate close to the support is higher than the other end which is symmetrical with the end, and the two symmetrical V-shaped transmission plates are V-shaped. The roller is arranged between the two adjacent V-shaped transmission plates. The material to be conveyed is placed between two rollers which are symmetrical along the centre line of the carriage. The technical solution of this conveyor is designed only for the purpose of winding copper material, such as copper strip or copper wire, on a reel, which can be rolled up into a cylindrical shape with a diameter of up to 2 meters for transport on a table during the copper processing operation.

And the existing fully-automatic conveying equipment has large volume and high cost, and for example, a logistics conveying device is disclosed in the publication of CN 2625350Y. The double-rail belt synchronous transmission rail is mainly characterized by comprising two parallel section bar supports, wherein one end of the rail is provided with two belt transmission wheels which are synchronously driven by a driving motor and are respectively arranged on the two section bar supports, and the other end of the rail is correspondingly provided with a belt driven wheel of the two belt transmission wheels. Such a transfer device is obviously too bulky.

In the logistics industry, the loading or unloading of the logistics articles still need to be carried to the conveying device by manpower, and when heavy articles are encountered, several persons are required to lift the heavy articles to the conveying device, and the logistics articles lifted by the persons are too costly if a crane is used.

In the moving industry, the furniture is manually assembled and disassembled, so that several people cannot pass through certain road sections when lifting the furniture, or the furniture cannot be changed after lifting the furniture, so that the moving personnel is very difficult to pay when sending the furniture into a truck, and even the furniture is damaged to compensate for owners, so that the moving personnel is unreliated.

When an old person needs to move a large object, the old person may be able to move the object but cannot keep moving for a long time.

In the field of transmission equipment, some large-scale transmission equipment needs to be shunted, the cost is too high due to the resetting of a shunting structure, and the structure is not easy to add.
