Description

Technical Field

[0001] The invention belongs to the technical field of railway wheel manufacturing, and in particular relates to a lifting device used in a railway wheel transport roller table and a use method thereof. Background Art

[0002] After sawing, rolling, heat treatment and finishing, the finished train wheels must pass through the inspection line for static balancing, marking, ultra-detection, magnetic flaw detection and surface strengthening of train wheels. At present, the wheels that have been finely processed by the lathe are sent to the transport roller of the inspection line through the lathe discharge roller. The roller structure is a double-row roller driven by a motor. In order to make the process layout compact and make rational use of the plant space, the lathe discharge roller and the inspection line transport roller are arranged vertically, and a turntable is set between the lathe discharge roller and the inspection line transport roller to realize the steering of the wheel on the roller. Considering the rotation of the turntable, a certain rotation distance is left between the turntable and the transport roller, which causes small-sized train wheels to slip or even fall off the track at the junction, seriously restricting reasonable production.

[0003] In order to solve the drawbacks of the turntable, the turntable is to be cancelled and a truss-type manipulator is used to achieve the overlap between the lathe discharge roller and the inspection line roller. The manipulator clamps the wheel rim with a claw to achieve the transition of the wheel between the two. When the wheel is transported on the inspection line, according to the inspection mark requirements, the inner rim surface or outer rim surface of the train wheel needs to be supported on two rows of rollers, and the manipulator has a certain thickness of claws. When the wheel needs to be transported on the roller with the inner rim facing down, if the manipulator turns the wheel with the outer rim facing down to the inner rim facing down and then directly falls on the roller, the manipulator claws will interfere with the roller surface.
