Abstract

The invention relates to a drag chain, in particular to a drag chain capable of protecting cables and a production method of the drag chain. The drag chain consists of chain links which are sequentially and continuously distributed. Each chain link comprises a pair of symmetrically distributed link plates. The link plates are positioned through supporting plates. Link sleeves are arranged at the heads of the link plates. Link sleeve chambers are arranged in the link sleeves. Front positioning pin holes are formed in the link sleeves. Rear positioning pin holes which are distributed corresponding to the front positioning pin holes are formed in the tails of the link plates. The tail of one link is inserted into the link sleeve chamber of another link. Rear limiting notches are arranged on the outer side walls of the tails of the links. Front limiting raised blocks which are adjustably clamped with the rear limiting notches are arranged in the link sleeve chambers. The production method comprises the steps of cutting and formation, heating, cooling, burr removal, pin hole and fixing hole processing, and electroplating. The drag chain capable of protecting cables and the production method thereof have the advantages that the structure is compact, the overhead performance is promoted, the bearing capacity is increased and the torsion strength is enhanced.

Description

technical field [0001] The invention relates to a drag chain, in particular to a drag chain for protecting cables and a preparation method thereof. Background technique [0002] The chain links in the towline in the prior art are limited by the limit pins, resulting in a very limited overhead length of the towline and increased use limitations. [0003] Chinese patent 200880112506.4 discloses a cable drag chain, which is formed by connecting a plurality of frames to each other rotatably. Long objects such as cables are arranged in the guide part surrounded by each frame. It is characterized in that it has : a rotation angle limiting mechanism that limits the rotation angle of the frame; and a brake mechanism that applies a brake to the rotation of the frame before the limit of the rotation angle, the rotation angle limiting mechanism is composed of a brake integrally formed on each frame The brake plate and the brake receiver are formed, and the rotation angle between the...
