Description

An automatic manufacturing equipment for anchor chain rings with controllable length

technical field

The invention relates to the technical field of anchor chain ring manufacturing, in particular to an automatic manufacturing equipment for an anchor chain ring with a controllable length.

Background technique

Anchor chain refers to a special chain that connects the anchor and the hull and transmits the anchor's grasping force. It is often composed of anchor end links, middle links and end links. There are two kinds of anchor chains, the strength of the former is greater than that of the latter. According to the manufacturing method, anchor chains can be divided into cast steel anchor chains and electric welding anchor chains. The length of anchor chains is in knots, and the standard length of each anchor chain is 27.5 m, and the joints are connected by connecting links or connecting shackles. Usually, the chain length of the main anchor on each side of the 10,000-ton ship is about 12 knots.

The anchor chain is a steel chain connecting the hull and the anchor. When manufacturing the anchor chain ring, it is necessary to consider the size of the hull to select the matching length of the anchor chain ring. In the manufacture of ordinary anchor chain rings, the anchor chain ring cannot be controlled. The length of the anchor chain ring may not necessarily require many different types of equipment to manufacture, which will not only increase the cost but also increase the error, so a controllable length of the anchor chain ring automatic manufacturing equipment is proposed to solve the problem. the questions raised above.
