Crankshaft hook

Abstract

The invention relates to a crankshaft hook which comprises a flying ring and a plate-shaped hook main body, wherein the lower part of the plate-shaped hook main body is an opened type semi-circular hook, the upper part of the plate-shaped hook main body is provided with a starlight plate, the flying ring is welded and fixed with the top surface of the straight plate of the plate-shaped main body, the outer side of the plate-shaped hook main body is provided with a handle, and the opened type semi-circular hook arranged at the lower part of the plate-shaped hook main body is internally provided with a crankshaft protecting cushion. When the crankshaft hook is used, the flying ring is cooperatively connected with a steel wire rope of a crane, and the handle is operated, so that the opened type semi-circular hook arranged at the lower part of the plate-shaped hook main body is embedded into a main shaft neck in the middle of a crankshaft, and the crankshaft can be stably hoisted when the crane starts up. The crankshaft hook is reasonable in structure, simple to construct, fast and convenient to operate, low in labor intensity, and safe and reliable, thereby being suitable for hoisting and transmitting the crankshafts among working procedures of processing lines.

Description

technical field [0001] The invention relates to a hoisting aid between crankshaft processing procedures, in particular to a crankshaft hook. Background technique [0002] We know that on the crankshaft machining line, most of the transfers between processes are carried out by means of small cranes, and the hooks used by the cranes are often made of bent steel bars. Since the hook is located in the middle of the crankshaft, the main journal and the cross-section of the steel bar are circular, and the crankshaft is in a swinging state during the lifting process. Therefore, it is necessary to hold the crankshaft by hand and transfer it to the processing machine tool for clamping. This method is not only labor-intensive, but also And it's not safe. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the above-mentioned prior art, and provide a crankshaft hook with reasonable structure, simple manufa...
