Connecting device for active beam and buttress beam of turnout

Abstract

The invention discloses a connecting device for an active beam and a buttress beam of a turnout. The connecting device comprises two moving F rails, connecting cross beams, angle adjusting mechanisms and supporting beams, wherein the two moving F rails are transversely symmetrically arranged along a track; the connecting cross beams are fixedly arranged on the lower surfaces, close to the buttress beam end, of the two moving F rails along the track line direction, and are used for connecting the two moving F rails; each angle adjusting mechanism is arranged at the other end, opposite to the corresponding connecting cross beam, of each moving F rail, and is used for properly adjusting relative deflection angle of the corresponding moving F rail and the active beam of the turnout; the supporting beams are arranged at the bottom parts of the connecting cross beams; one end of each supporting beam is fixed to a supporting beam base which is mounted on the active beam of the turnout, and the other end of each supporting beam extends toward one end of the corresponding cross beam, and the extending end is fixed to the bottom end of the corresponding connecting cross beam. With the adoption of the connecting device, the vertical stiffness of the connecting device between the active beam and the buttress beam can be improved on the premise that the degree of vertical freedom and the degree of left and right freedom of the active beam of the turnout are limited after the active beam moves in place, and the stability of the connecting device of the turnout is improved, so that a train can be prevented from jumping while running through a connecting part, and a route is stable and smooth.

Description

technical field [0001] The invention belongs to the technical field of low- and medium-speed maglev track turnouts, and in particular relates to a connecting device used between active beams and stacking beams of a turnout. 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 de...

Problems solved by technology

[0005] However, the positioning connection device in this scheme also has obvious defects, that is, when the train passes through the connection device, the pressure acting on the movable end of the F rail completely acts on the guide wheel assembly and the extension end of the web of the switch beam. The unbalanced force will cause the vertical jump of the F rail; on the other hand, the lack of strength or stiffness of the connecting device in the vertical direction and instability will weaken the bearing capacity of the connecting device and reduce the bearing capacity of the entire track, which will lead to Decreased driving safety and stability
