Cast-molded lifting hook

Abstract

The invention provides a cast-molded lifting hook. The lifting hook comprises a lifting ring, a connecting hole in the middle of the lifting ring, a hook part hinged to the lifting ring and a bearing hole formed in the central axis direction of the hook part; the lifting hook is characterized in that upper fixing shafts are arranged on two sides of the lifting ring; lower fixing shafts are arranged on two sides, close to the lifting ring, of the hook part; spring pieces are connected between the upper fixing shafts and the lower fixing shafts; reinforcing bodies are arranged on two sides of the bottom of the hook part and surround the central axis of the bearing hole; and a bulge body is arranged at the tail of the hook part. According to the lifting hook, elastic pieces are arranged between the lifting ring and the hook part and have a buffering effect, and the condition that a carried object is thrown out due to excessively large swing amplitude of the hook part in the running process is avoided; the position of the bearing hole is reinforced, and breakage under the relatively large stress is avoided; and the bulge body is added to the tail of the hook part and has a stop effect, and the potential safety hazard caused by the fact that the object slides along the bearing hole in the conveyed process and separates from the lifting hook is avoided.

Description

technical field [0001] The invention specifically relates to a cast-molded suspension hook. Background technique [0002] The hook is a kind of spreader commonly used in hoisting machinery. It is generally composed of a suspension ring and a hook connected to the suspension ring. Inertia, when the ring and the hook part are connected separately, the ring and the hook are not on the same straight line, and the object on the hook body is easy to slip off the hook body under the influence of its own gravity. At this time, the joint of the hook body bears the force along the direction of motion, which easily breaks the joint between the suspension ring and the hook portion, causing potential safety hazards. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the technical solution provided by the present invention is: a casting hook, including a suspension ring, a connecting hole in the middle of the suspension ring, a hook part hinged...
