F-track movable end positioning and connection device for medium-and-low-speed magnetic suspension turnout

Abstract

The invention discloses an F-track movable end positioning and connection device for a medium-and-low-speed magnetic suspension turnout. The F-track movable end positioning and connection device comprises two sections of F-track movable ends which are symmetrical left and right. A movable hinged support is fixedly connected with the lower part of the rear end of each of the two sections of F-track movable ends which are symmetrical left and right; each movable hinged support consists of a pair of ear plates, an upper connection plate, a front side plate and a pin roll; the upper connection plate is fixedly connected with the upper ends of the pair of the ear plates and the lower part of the F-track movable end, and the front side plate is fixedly connected with the front end of the pair of the ear plates and the lower part of the upper connection plate; and the pair of the ear plates are inserted into two sides of an extension end of a turnouttrack web of the turnout and are hinged with two sides of the extension end of the turnouttrack web of the turnout through the pin roll, each front side plate is provided with an adjusting screw and the front end of the adjusting screw is pressed against the extension end of the turnouttrack web of the turnout. The left and right freedom degree of the F-track movable end positioning and connection device is limited on the premise that thevertical freedom degree of the device is limited, and the turnout is prevented from swinging left and right and jumping in a vertical direction.

Description

technical field [0001] The invention belongs to the technical field of turnout design for medium and low-speed maglev transportation systems, and in particular relates to a positioning and connecting device for the movable end of an F rail of a medium-low speed maglev turnout. 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 vertical positioning device for the movable end of the F rail of the medium and low speed maglev turnout is an important part of the medium and low speed maglev turnout. It is a device for docking and positioning the F rail on the movable beam of the turnout and the F rail on the fixed beam. The device should be able to move flexibly with the turnout beam, and the vertical degree of freedom should be restricted after moving in place, so that the F rail at the movable end can be ...
