Embodiment 1

[0022] Embodiment 1: with reference to attached Figure 1-3 . A high-speed maglev turnout floating support driving device, which consists of a driving rack 1, a driving gear 2, a driving shaft 3, a trolley frame 4, a trolley wheel 5, a driving motor 6, a running rail 7, a guide wheel 8, a guide rail 9, In this structure, racks 1, running rails 7, and guide rails 9 are arranged on the basic bottom plate 10, and they are all arranged in a concentric circle in the layout form; the trolley wheels 5 and the trolley frame 4 are axially fixed together , the trolley wheel 5 can only realize rotation relative to the trolley frame 4; the drive shaft 3 penetrates the trolley frame 4 and the trolley wheel 5 to realize rotary motion, and the two sides of the drive shaft 3 are respectively provided with torsion sliding rods 11 and one end of the torsion sliding rod 11 Connected with the trolley frame 4, the other end of the torsion sliding rod 11 is slidably matched with the connecting rod...

Embodiment 2

[0030]Embodiment 2: On the basis of Embodiment 1, a driving method for a high-speed maglev turnout floating support driving device, the driving motor 6 drives the driving gear 2 to rotate through the driving shaft 3, and the driving gear 2 is connected to the base plate 10 installed on the base The drive rack 1 meshes to drive the trolley frame 4 to move, thereby dragging the turnout beam installed on the trolley frame 4 (the turnout beam is installed in the middle and upper part of the trolley frame, and is connected to the trolley frame by bolts, and the turnout beam is not included in this In the system) move to realize the switch, because the turnout beam is a flexible beam body and the influence of the turnout timing sequence, the track of the platform wheel 5 is an irregular curve and the track is not unique during the switch process, and a circular curve is fitted The shape of the running rail 7 is to meet the actual walking of the trolley. During the movement, it is aff...

Abstract

The invention relates to a high-speed magnetic levitation turnout floating type supporting driving device and a driving method. The high-speed magnetic levitation turnout floating type supporting driving device is composed of a driving rack, a driving gear, a driving shaft, a bogie frame, bogie wheels, a driving motor, a walking rail, guide wheels, a guide rail and a foundation bottom plate. The rack, the walking rail and the guide rail are arranged on the foundation bottom plate in the structure; the bogie wheels and the bogie frame are axially fixed together, and the bogie wheels can only rotate relative to the bogie frame; the driving shaft penetrates into the bogie frame and the bogie wheels to realize rotary motion; and torsion sliding rods are arranged on the two sides of the drivingshaft respectively, one ends of the torsion sliding rods are connected with the bogie frame, the other ends of the torsion sliding rods are in sliding fit with the connecting rods, a guide device isconnected with the connecting rods, the two guide wheels located below the guide device are clamped on the two sides of the guide rail, and the bogie frame and the bogie wheels can axially slide on the driving shaft. A problem of rail gnawing of a bogie wheel edge during turnout beam switching is solved, stability of turnout switching is guaranteed, abrasion between the bogie wheel and a rail is reduced, and a service life is prolonged.

Description

technical field [0001] The invention relates to a high-speed maglev turnout that can not only solve the problem of rail gnawing at the edge of the trolley when the turnout girder turns, ensures the stability of the turnout, but also reduces the wear and tear of the trolley wheel and the track, and improves its service life. The invention discloses a type supporting driving device and a driving method, belonging to the field of manufacturing high-speed maglev turnout supporting driving devices. Background technique [0002] CN101294365B, title "rail changing device for magnetic levitation track and structural assembly for its manufacture", comprising a driveway part (1, 41, 48), at least one set transversely to the driveway part (1, 41, 48) The guide rail (17) and a driven support (31) supporting the carriageway part (1, 41, 48), said support has at least two rollers (16) supported on the guide rail (17), its characteristic In that, the support (31) comprises a support modul...
