Recently, with the increase of the requirements of electric control, green manufacturing and light weight, the complexity of the shape and structure of the connecting rod is gradually increased. All parts of the connecting rod of the marine diesel engine are machined surfaces, the connecting rod needs to be machined on various machine tools, and a connecting rod workpiece is often required to be turned over and refuted for lifting for multiple times according to different machining states in the machining process.
At present, the hoisting and turning-over operation of the marine diesel engine connecting rod adopts the combination of a steel wire rope, a lifting hook and a coating material to turn over, and no special tool is provided. The traditional connecting rod workpiece hoisting method has many defects: the position of a steel wire rope is not easy to control in the lifting process, the steel wire rope and the rod body can slide, the rod body is easy to unbalance due to carelessness, the connecting rod falls, a machined surface on the connecting rod can be damaged, and equipment or personal safety accidents can be caused seriously; in addition, the danger degree of the hoisting operation is very high, the requirement on the skill level of hoisting personnel is very high, and the safety production can be ensured by equipping special hoisting workers. Therefore, the existing hoisting mode has the defects of low working efficiency, high labor intensity and high operation difficulty, and has numerous accident hidden dangers of quality, equipment, safety and the like.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the defects of the existing hoisting mode and provide a hoisting tool for a connecting rod of a WINGD type marine diesel engine, so that the hoisting and turning of the connecting rod among processing stations are realized in the processing process, and the effects of safety, high efficiency and convenience are achieved.
In order to achieve the above object, the technical solution of the present invention is as follows:
the utility model provides a lift by crane frock for WINGD type marine diesel connecting rod, the both ends of marine diesel connecting rod are thin end and thick end respectively, are equipped with the screw hole on this thin end, are equipped with on the thick end and connect screw, its characterized in that: the lifting tool comprises a lifting bolt and a special lifting seat, the lifting bolt is screwed on the screw hole of the thin end, the special lifting seat is fixed on the connecting screw hole of the thick end through a bolt, the special lifting seat comprises a bottom plate and a lifting plate, the lifting plate is perpendicularly welded on the bottom plate, lifting holes used for connecting a lifting hook and a steel wire rope are arranged, and the bottom plate is provided with fixing holes used for installation.
Further, the lifting bolt is a rotary lifting bolt.
Furthermore, a plurality of groups of connecting screw holes are formed in the marine diesel engine connecting rod, and the position of each group of connecting screw holes corresponds to the position of the fixing hole in the bottom plate of the special hoisting seat.
Furthermore, the bottom plate and the hanging plate are made of steel plates.
Compared with the prior art, the utility model has the beneficial effects that:
1) after the hoisting tool is used, the lifting hook is connected with the rotary lifting ring screw through one end of the steel wire rope, and one end of the lifting hook is connected with the special hoisting seat, so that the marine diesel engine connecting rod is stably hoisted and turned over, the phenomenon that the steel wire rope directly contacts with the rod body to cause sliding between the rod body and the rod body is avoided, the rod body is unbalanced, the machined surface on the connecting rod is damaged by falling, and even safety accidents are caused.
2) The utility model has the advantages of simple operation and high operation efficiency.
In a word, the utility model ensures the safety and convenience of the lifting and turning over of the connecting rod in the processing process and improves the operation efficiency.

Detailed Description
The present invention will be described in further detail with reference to the following drawings and examples, but the scope of the utility model as claimed should not be limited thereby.
The connecting rod of the marine diesel engine is used for hoisting and turning over the connecting rod of the marine diesel engine in the machining process, please refer to fig. 1, two ends of the connecting rod of the marine diesel engine are respectively a thin end A and a thick end B, the thin end A is provided with a screw hole A1, and the thick end B is provided with a connecting screw hole B1.
The hoisting tool comprises a hoisting ring screw and a special hoisting seat; the lifting ring screw is screwed on the screw hole A1 of the thin end A, and the special hoisting seat is fixed on the connecting screw hole B1 of the thick end B through a bolt.
