Transition device for guiding surface or stabilizing surface between girders of straddling articulated turnout

Abstract

A straddling type joint turnout beam-to-beam guide face or stable face transition device is composed of connecting bolts, a flexible panel, a slide plate, a slide base plate and a fixing base. The connecting bolts penetrate through the fixed end of the flexible panel and the fixing base to be fixedly connected with the side vertical face of a first turnout beam. The slide base plate and the side vertical face of a second turnout beam are in bolt fit, and the upper side and the lower side of the outer end face of the slide base plate are provided with slide grooves. The slide plate is mounted in the slide grooves to freely slide through slide rails on the upper side and the lower side of the slide plate. The slide end of the flexible panel is fixedly connected with the outer end face of the slide plate through the connecting bolts to enable the flexible panel to be located between guide face or stable face connectors of the first turnout beam and the second turnout beam, and the outer vertical face of the flexible panel is flush with the guide faces or the stable faces of the first turnout beam and the second turnout beam. By adoption of the straddling type joint turnout beam-to-beam guide face or stable face transition device, the problem of mutual impact when a vehicle passes through the turnouts can be solved, traveling comfort and safety of the monorail vehicle are ensured, and the high-speed passing-through demand of a small-traffic-volume straddling type rail traffic system is met.

Description

technical field [0001] The invention belongs to the technical field of urban rail transit, and in particular relates to a transition device for guiding surfaces or stabilizing surfaces between girders of a straddling articulated turnout. Background technique [0002] The straddle-type articulated turnout is composed of multiple beam sections connected, and each beam section of the articulated turnout beam always maintains a straight line state, and there are relative rotation angles between adjacent beam sections. The articulated turnouts in the prior art, such as the single-track articulated turnouts used in the Chongqing straddle rail transit system, transition through the finger plates between the beams. Although the finger plates realize the continuous contact between the wheel lintels, However, the finger plate is a rigid body, and there is always a broken line transition between the beams. The broken line angle will have an impact on the wheel, affecting the service li...
