Embodiment 1

[0016] Embodiment 1: with reference to attached Figure 1-5 . A straddle-type monorail replacement beam single-crossing turnout equipment, the turnout is installed on the foundation floor 1-1 as a whole, and two supporting trolleys 1-5 are respectively used to support the front curve turnout beam and the rear curve at the center of rotation of the beam replacement turnout The turnout beam, and the curve connecting beam 1-7 is between the front curve turnout beam and the rear curve turnout beam, and the curve connection beam 1-7 is composed of the front curve turnout beam and the rear curve turnout beam, and the curve curve connection beam 1-7 is installed on a fixed On the supporting pier, the fixed supporting pier is used to connect the front curved turnout beam and the rear curved turnout beam, and two supporting trolleys 2 1-6 are respectively used to support the straight turnout beam 1-4 at the center of rotation of the beam replacement turnout, The driving running device...

Embodiment 2

[0027] Embodiment 2: with reference to attached Figure 6 and 7 . The detailed working method of the turnout: the turnout is installed on the foundation floor 1-1 as a whole, the supporting trolley 1-5 and the supporting trolley 2 1-6 are used to support the straight and curved turnout beams 1-4, and walk on the foundation floor ; The drive running device 1-3 provides power for the turnout switch and supports the turnout beam 1-4, and the drive gear 3-4 meshes with the rack 2-3 to push the switch drive running device 1-3 to move, thereby dragging the turnout beam 1-4 Rotate a certain angle along the predetermined position, and connect with the corresponding track beam to form a branch road, that is, to realize Figure 6 The turnout is open to traffic in a straight line, or Figure 7 Turnout curve opening state; connecting stack beams 1-7 are installed on fixed support piers and fixed on the foundation for connecting curved turnout beams. The locking device 1-2 adopts a bol...

Abstract

The invention relates to straddle-type monorail substitute beam single-crossover turnout equipment and a rail switching method. A turnout is integrally mounted on a basic bottom plate, and two first support platform trucks are used for supporting a front curved turnout beam and a rear curved turnout beam respectively, wherein the front curved turnout beam and the rear curved turnout beam are located at the turning center of the beam substitute turnout; a curved engagement beam is located between the front curved turnout beam and the rear curved turnout beam and is mounted on a fixed support pier and used for being connected with the front curved turnout beam and the rear curved turnout beam; two second support platform trucks are used for supporting straight turnout beams respectively, wherein the straight turnout beams are located at the turning center of the beam substitute turnout; a drive walking device provides power for turnout switching and supports the straight turnout beams; in the drive walking device, a drive gear meshes with a rack, in this way, the drive walking device is driven to move, and therefore the straight turnout beams are dragged to rotate by a certain degreealong a preset position and are in butt joint with corresponding rail beams to form the turnout; according to a locking device, a bolt locking mode is adopted, and after the turnout rotates in place,a locking bolt is inserted into a locking groove to achieve locking.

Description

technical field [0001] The invention relates to a straddle-type monorail replacement beam single-crossing turnout equipment, which can not only realize the smooth running of the turnout, the accurate position, but also can combine two sets of turnouts into a set of single-crossing turnouts by adding connecting stacking beams, which belongs to the monorail single-crossing Line turnout equipment manufacturing field. Background technique [0002] The straddle type single track turnout can be divided into pivot type (including joint type and joint flexible type), translation type turnout, and beam replacement type turnout. Each beam section of the articulated turnout always maintains a straight line state, and there are relative broken line corners between adjacent beam sections. The broken line angle will impact the wheel, affect the service life of the wheel, and bring about violent swing of the vehicle body at the same time. Joint-type flexible turnouts have a continuous li...
