Abstract

The invention relates to a special lifting hook for a K type derrick. The special lifting hook is formed by combining an 8-shaped steel wire rope and a safe lifting hook and is provided with the 8-shaped steel wire rope and the safe lifting hook, wherein the upper part of the 8-shaped steel wire rope is a small circle ring, the lower part of the 8-shaped steel wire rope is a large circle ring, the upper part of the safe lifting hook is an oblate lifting hole, the lower part of the safe lifting hook is a bent hook, the large circle ring of the 8-shaped steel wire rope passes through the oblate lifting hole of the upper part of the safe lifting hook, the small circle ring penetrates out of the large circle ring and is straightened, and the 8-shaped steel wire rope and the safe lifting hook are combined into the special lifting hook for the K type derrick. The special lifting hook has the advantages that the special lifting hook for the K type derrick is convenient to install and can not be unhooked, the safety coefficient is reliable, and the wire breakage and the deformation of the steel wire rope can not be caused.

Description

technical field [0001] The invention relates to the field of machinery manufacturing, in particular to a special hook for a K-shaped derrick composed of an 8-shaped steel wire rope and a safety hook. Background technique [0002] Known oil drilling K-type derrick is used in the dismantling, transfer, and installation process as an auxiliary tool. The steel wire rope is easy to slip during use, which brings hidden dangers to safety, and the steel wire rope is often broken, bent, and deformed, resulting in Scrapping is a big waste, and there has been no good technical solution for this drawback. Contents of the invention [0003] The purpose of the present invention is to provide a special hook for K-type derrick, which is not only easy to install, will not slip, has a reliable safety factor, and will not cause the problems of wire rope breakage and deformation. Disadvantages of derricks. [0004] In order to achieve the above object, the special suspension hook for K-type...
