Problems solved by technology

Therefore, when the maglev train passes, it will generate vibration, which will affect the ride comfort and the service life of the switch
In the prior art, in order to reduce the vibration, the method of adding a damper to the turnout beam is generally adopted, but this method is more complicated and the cost is very high

Abstract

The invention provides a trolley limiting device of a magnetic suspension railroad switch. The trolley limiting device comprises a limiting component which is connected with a trolley foundation plateand a limiting shaft connected with a trolley crossbeam, wherein the free end of the limiting component is located on the free end of the limiting shaft, and is provided with a part which can be in contact with the free end of the limiting shaft. Through the adoption of the trolley limiting device disclosed by the invention, vibration generated on a trolley and a railroad switch beam when a magnetic suspension train passes can be reduced or removed; and the trolley limiting device is simple in structure and convenient to mount and maintain, so that the cost is low.

Description

technical field [0001] The invention belongs to the technical field of maglev turnouts, and in particular relates to a trolley limiting device for maglev turnouts. Background technique [0002] Because of the advantages of safety, comfort, strong climbing ability and low noise, medium and low-speed maglev transportation has broad development prospects as a new urban rail transit mode. The medium and low-speed maglev turnout trolley is an important mechanism of the maglev turnout. It is installed under the turnout beam and has a supporting effect on the turnout beam. The trolley walks on the running track during the switching process, and there is only a vertical downward limit but no vertical upward limit in the vertical direction. Therefore, when the maglev train passes, vibration will be generated, which will affect the ride comfort and the service life of the switch. In the prior art, in order to reduce vibration, a method of adding a damper to the turnout beam is gener...
