The fork device used between the movable beams of the articulated magnetic levitation turnout

Abstract

A fork poking device used between moveable beams of a maglev switch, comprising a fork poking hinge mechanism and a fork poking unit, the fork poking hinge mechanism comprising a base (7) and a hinge shaft (2) provided on the base (7), a sliding sleeve (3) and an antifriction plate (5) being coaxially sleeved on the hinge shaft (2) successively from inside to outside, the rotation of the hinge shaft (2) being able to drive the sliding sleeve (3) and the antifriction plate (5) to rotate; the fork poking unit comprises a fork poking plate (10), the middle portion of an extended end thereof being open to form an U shape having two legs; the hinge shaft (2) of the fork poking hinge mechanism and the sliding sleeve (3) and the antifriction plate (5) are used to pass through the opening of fork poking plate (10) such that, when the rotation of a driving beam drives the antifriction plate (5) to rotate, the fork poking plate (10) is driven by means of a frictional force to rotate accordingly, thereby driving a driven beam to rotate accordingly. Said fork poking device is not only able to ensure the driven beam to be driven to rotate together with the driving beam when the driving beam rotates, but also decreases the frictional resistance during the fork poking process, better smoothing the rotation of the driven beam driven by the driving beam, reducing the wear of the fork poking hinge mechanism, and improving the abrasion resistance performance and the service life of the fork poking device.

Description

technical field [0001] The invention belongs to the technical field of medium and low-speed maglev track switches, and in particular relates to a fork device used between movable beams of joint-type maglev track switches. Background technique [0002] Turnout is a line connection device used in rail transit to transfer rolling stock from one track to another. It is usually laid in the throat area of ​​a station or at the intersection of two lines. The turnouts of medium and low speed maglev rail transit usually include turnout beams, stacking beams, trolleys, beam upper guide rails, driving devices, locking devices, movable end guide rails, and electrical control systems. When the train needs to change lanes, through the control of the electrical system, The locking device is unlocked, and the turnout beam moves from one track to the other under the action of the driving device. After the track at the movable end is flush with the track on the stacking beam, the locking devi...

AI Technical Summary

Problems solved by technology

[0004] On the one hand, the existing switch fork device has a complex structure and is difficult to manufacture and process. On the other hand, its structure makes the frictional resistance large during the fork shifting process. The driven beam rotates slowly with the active beam, and the rotation is not smooth enough, resulting in low efficiency and may affect the smoothness of the track
