Friction wheel-type heavy cargo carrying platform and storing and taking method

Abstract

The invention discloses a friction wheel-type heavy cargo carrying platform and a storing and taking method, and belongs to the field of heavy stacking. The friction wheel-type heavy cargo carrying platform comprises a cargo carrying rack, sliding rail assemblies, a friction wheel micro-feeding mechanism, friction wheel holding mechanisms and a guide rail tray, wherein the cargo carrying rack is of a frame structure, the friction wheel micro-feeding mechanism is installed in the middle of the upper end of the cargo carrying rack, and the friction wheel holding mechanisms are symmetrically installed at the two ends of the cargo carrying rack; the sliding rail assemblies are installed at two sides of the cargo carrying rack; the friction wheel micro-feeding mechanism feeds a driving motor 17 to drive the clamping rack to slide along a linear guide rail; the two friction wheel holding mechanisms are driven by a holding driving motor 8 to realize reverse rotation of two friction wheels; and a tray holding frame of the guide rail tray is clamped by two friction wheels, and the guide rail tray is driven to reciprocate along the guide rail of the guide rail through reverse rotation of the two friction wheels. A lead screw, a gear and a chain are adopted for transmission, so that the structure is simple, transmission is stable, and precision is high; and the guide rail is used as a guide part, so that the stored and taken goods can stably reach a specified position.

Description

technical field [0001] The invention belongs to the field of heavy-duty stacking, and in particular relates to a friction-wheel type heavy-duty loading platform and a storage and retrieval method. Background technique [0002] The automated three-dimensional warehouse has the advantages of high space utilization, intelligent access, and labor cost savings. With the continuous development of automated production lines and intelligent logistics, automated three-dimensional warehouses have become the inevitable development direction of storage equipment. Roadway stacker is a special crane developed with the emergence of three-dimensional warehouses. It is generally composed of upper and lower beams, columns, lifting mechanisms, horizontal walking mechanisms and cargo platforms. The cargo platforms are used as components for direct access to goods. Different industries There are different demands on cargo bed structures. At present, the common stacker loading platform is a fork...

Problems solved by technology

At present, the common stacker loading platform is a fork-type loading platform. When storing and withdrawing goods, the goods are stored through the telescopic lifting action of the fork. Since this type of fork-type loading platform is a cantilever beam structure, the access length is longer For long and heavy bar goods, the fork has a large deflection, and long-term use will cause the deformation of the fork and the decrease in positioning accuracy. Therefore, the rigidity of the fork, the performance of the supporting motor and the rigidity of the pallet are very high.

Aiming at this phenomenon, the present invention develops and designs a friction-wheel-type loading platform to replace the original fork-type loading platform, and solve the problem of large fork deflection when storing long and heavy bar goods, so as to realize long-heavy and heavy-duty storage. Three-dimensional storage safety and stability of bar goods
