Description

Wire rope hook manufacturing device and towing rope forming the loop

The present invention is an automatic ring device for integrally forming the hook of the wire rope fastened to the crane hook to tow the heavy weight when moving the heavy weight to the crane in the crane operation of the ship vehicle unloading operation, or the traction operation for transporting heavy materials In particular, the present invention relates to a wire rope loop manufacturing apparatus which enables a simple manufacture of an eye on a traction wire rope by automatic operation.

As is well known, when moving a heavy object using a crane, the heavy material is carried by the crane, and at this time, a wire rope connected to the hook of the crane is used while supporting the heavy object.

These wire ropes form eye hangs on both ends of a certain size rope as known in the art to bundle the heavy goods in the rope or to support the lower part of the heavy goods, and to hang the ropes on the hooks of the cranes so that the crane can move the heavy goods. It consists of one configuration and the loop forms the end of the rope in an "o" shape, while the connection of the loop is intertwined with the eye splice and the compression stop and clip stop (U- bot onTension End) type.

These wire ropes require the strength and rigidity to support heavy loads, and use wire ropes with a diameter of about 10-50 mm depending on the weight used. Separate the strands of the rope into strands (consisting of about six strands) by size and form loops in the form of "o" and then separate each strand again at the junction, ie at the junction. Along with this process, the process of penetrating the separated company into this separated space constitutes a loop that connects with several twists.

That is, after forming the tail, the twist of the rope outside the point where the knot of the loop meets, and the unwrapped yarn is rotated in the opposite direction again to penetrate into the space formed between the strands. It will be reversed.

Accordingly, by inserting each strand separated at the end into the unwinded twist in the space formed between them in the state where the strands are open, the twist is repeated several times with the rope again so that the end is joined with the one-rope and a ring is formed. will be.

This work can be done with a wire rope of 10mm diameter as human power and technology, but in contrast, when the diameter exceeds 30mm, the wire rope cannot be bent by human force. Therefore, various types of towing devices, such as using a car pull and warp, a lot of people at the same time using a method, such as this method is extremely difficult and the efficiency of the work, such as the work requires a considerable amount of technical This work is avoided by the inability to obtain skilled workers and demanding a lot of labor.

In addition, the tow rope (eye splice) composed of the above operation is beautiful and robust and safe as the connecting portion of the loop is twisted together with the rope, but the wires of the cut rope yarns of the connected strands are exposed to the worker's hand during the towing operation. Accidents that cause injury are frequently occurring.

In other words, the twisted yarns are exposed to the outside from the connection portion is formed in the shape of a sharp pin peculiar to the steel wire, when the worker grabs such a rope, the steel wire pokes the worker's hand, causing a lot of accidents during work.

In order to correct such a closed end, the hazardous yarn is removed by a package (compression stop) in which lead is melted in the connecting twist or cutting of the yarn by a welding means. There is a disadvantage in that it is easily broken by pressure, and in the welding means, the removal of the yarn is not certain, and when cutting at a high temperature, heat-melting important yarns together with the hazardous yarns greatly damages the strength of the rope's traction.

Therefore, the damage caused during the work is easily cut off accidentally occurring.

In order to solve the above drawbacks, clip stops for fastening the loop-connected joints with 'U' bolts are used. However, bolt fastening is effective in manual work, but the bolts are not firm and the bolts are loosened. As there are many accidents during work, it has a disadvantage that cannot be used in towing work of heavy materials.

Along with the above-described manual work and simply forming a ring, the technique has been known from Japanese Patent Application Laid-Open No. 57-83199, but such a configuration is suitable for winding a connection part or a table with a wire in the above-mentioned hand. The above problem has not been improved.

The present invention has been devised for the purpose of mass production of a ring formed by a conventional manual work with an automated device, in particular, by supplying a wire rope cut to a certain size bent into a ring and the end of the ring The separation of the company strands in the ring and also the connection section side of the ring separates the company strands in the reverse rotation, and between each of the separated company strands inserted the strands of the separated end between the open strands between the strands of the aberration, both ends. To provide a tow rope automatic manufacturing device to form a ring.
