Description
Technical field
The present invention relates to drag chain technical fields, and in particular to a kind of long range heavy duty drag chain bearing device.
Background technology
The occasion that drag chain is suitable for moving back and forth, in numerically-controlled machine tool, mechanical arm, handling equipment, Automatic Warehouse etc.
Automation equipment field is widely used, and can play traction and protective effect to built-in cable, oil pipe, tracheae, water pipe etc..
Drag chain heavily loaded over long distances can be divided into three parts during the motion：Drag chain hypomere, drag chain turn to ring segment and drag chain
Epimere, drag chain hypomere are laid on the bearing support of drag chain, and drag chain epimere is stacked in due to heavy duty over long distances under drag chain
The top of section, and the steering ring segment of drag chain then forms ring seal shape, since drag chain epimere is stacked on drag chain hypomere, in drag chain
It can rub to drag chain hypomere in epimere moving process, drag chain can be seriously worn in the case of heavy duty.
To solve the above-mentioned problems, Chinese patent literature CN104085657A discloses a kind of long range heavy duty drag chain support
