Description

Technical Field

[0001] The utility model relates to the technical field of suspension conveyors, in particular to an accumulation type suspension conveyor. Background Art

[0002] The power-and-free overhead conveyor is a three-dimensional closed-loop continuous conveying system suitable for the automated transport of finished goods within and between workshops. It is widely used in modern industrial production in industries such as machinery, automobiles, steel rolling, aluminum smelting, light industry, home appliances, chemicals, and building materials.

[0003] The accumulation type overhead conveyor in the prior art suspends the workpiece on the conveying vehicle group through hooks when in use. However, when suspending larger workpieces, multiple hooks are needed to fix the workpiece together.

However, in the prior art, the hooks are fixedly connected to the conveying vehicle group through iron chains. In order to be suitable for workpieces of different sizes, additional hooks need to be set up, which increases the transportation cost and the hooks that do not suspend the workpiece will also affect the suspension of the workpiece, thereby affecting the transportation efficiency of the workpiece.
