Switching hook of crane lifting hook

Abstract

The invention provides a switching hook of a crane lifting hook. The switching hook comprises a switching part and a hanging part, wherein the switching part comprises a switching ring, a switching loop is formed in the space in the switching ring, and the switching loop is of a closed quasi-circular structure, the hanging part comprises an object hanging ring and an anti-falling block, a U-shapedobject hanging loop is formed in the space in the object hanging ring, and the switching ring is fixedly connected with the object hanging ring. The switching hook has the advantages that through unique angle design, the switching hook of the crane lifting hook is designed, conversion connection between the crane lifting hook and a gas turbine tool lifting eye is achieved to complete assembly operation of a gas turbine, and the situation that due to mismatching of connection, operation is difficult, and potential safety hazards are caused is prevented, meanwhile, an automatic anti-disengagingfunction is achieved, an anti-disengaging block is automatically located at the position limiting disengaging of the lifting hole in the object lifting ring during lifting, and use safety is improved, the switching hook is integrally formed and welded, so processing cost is saved while the strength is ensured.

Description

technical field [0001] The invention belongs to the technical field of engineering hangers, and in particular relates to an adapter hook for a driving hook. Background technique [0002] Due to the fixed specifications of the crane hooks, it cannot be applied to hoist all devices in the same workshop. In order to adapt to different devices, the process of replacing the crane hooks is cumbersome and the cost of purchasing too many crane hooks is huge; therefore, the workshop usually adopts the crane hook transfer hooks to reduce costs and complete lifting tasks. In the production and processing workshop of gas turbines, the hoisting adapter is the link between the crane and the gas turbine and its parts. It is an important tool to ensure the assembly of the gas turbine, and it is also closely related to the personal safety of the operator. [0003] At present, on the market and on the Internet, the size of the crane hook adapter of any specification cannot match the size of ...

Problems solved by technology

[0003] At present, on the market and on the Internet, the size of the crane hook adapter of any specification cannot match the size of the lifting eye on the tooling of the gas turbine, which cannot guarantee the product processing requirements and the safety of personnel, which brings great obstacles to the operation and product shipment. , so it is urgent to design a driving hook adapter hook suitable for gas turbine engine tooling
