Description

A built-in pneumatic wheel set turntable

technical field

The invention relates to the technical field of production and maintenance process equipment for railway vehicle wheelsets, in particular to a built-in pneumatic wheelset turntable.

Background technique

At present, the turntables used by the production and maintenance enterprises of railway vehicle wheelsets include electric turntables and pneumatic turntables (also known as rotary picks) when the railway wheelset passes through the production and maintenance lines. The price of the electric turntable is higher, and the maintenance cost is also higher; the pneumatic turntable directly jacks up the wheel set from the middle of the axle for manual or automatic reversing. It is not suitable for wheel sets with gearboxes and brake discs, as well as wheel sets for passenger cars, urban rail and high-speed trains. At the same time, because the rotary pick is higher than the ground, it affects the overall aesthetics and safe production of the workshop, and is gradually being eliminated by the enterprises that use it. .
