Abstract

The invention discloses a lifting device for a metro bogie, and relates to the technical field of metro vehicle lifting devices. The device comprises a first half lifting hook, a second half lifting hook, an adjusting pad and a cotter pin; the second half lifting hook comprises a second half circular truncated cone, a second half cylinder, a second half ring table and a second half connecting column. The lifting device has the beneficial effects that the lifting device can penetrate two equal-diameter unthreaded holes at the same time, connection of the lifting device and the interior of a lifted part is achieved, in the mounting and dismounting process, operation from one side of the lifted part is achieved, on the other side, operation space does not need to be assisted or provided, after mounting, the lifting function can be achieved without fixing, a split structure is adopted in the lifting device, the two half lifting hooks are of an integral molding structure, and the lifting strength can be ensured; the matching face of the two half cylinders is designed with the slope and the radian, in the lifting process, self locking of a certain degree can be achieved under the effect of the self weight of the lifted object, and the safety of the lifting process can be ensured.

Description

technical field [0001] The invention relates to the technical field of lifting devices for subway vehicles, in particular to a lifting device for a subway bogie. Background technique [0002] At present, the subway hoisting devices used at home and abroad are mostly external connection structures due to the limitation of installation and operation space, which need to occupy the installation and layout space of other equipment, and are inconvenient to disassemble. This externally connected lifting device cannot realize the connection of the two parts of the equal-diameter double holes from the inside, for example, the connection and lifting of the framework of the bogie and the bolster cannot be realized. [0003] In view of the current situation at home and abroad, it is urgent to design a lifting device that does not occupy external space, is easy to install and disassemble, and can be connected from the inside. Contents of the invention [0004] In order to solve the t...
