Embodiment Construction

[0027] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0028] refer to figure 1 , figure 2 , image 3 , Figure 8 and Figure 9 , the present invention can quickly adjust the medium and low speed maglev variable gauge track structure, including the buckle row composed of the left sleeper 11, the right sleeper 12, the F-shaped guide rail 7, the rail support platform 5 and the fastener system 3, and the horizontal interval The left sleeper 11 and the right sleeper 12 are arranged in pairs along the line extension direction, and the F-shaped guide rail 7 is fixedly installed on the top surface, and each left sleeper 11 and right sleeper 12 pass through the fastener system 3 and the rail bearing platform below it 5 to form a connection. The cross-sections of the left side sleeper 11 and the right side sleeper 12 are I-shaped, and U-shaped plates 20 corresponding to their contours are respectively arranged...

Abstract

The invention discloses a medium-low speed maglev variable-gauge track structure capable of being quickly adjusted, which is convenient for realizing quick adjustment of the gauge, greatly reduces repeated test line engineering construction cost, and is beneficial to guaranteeing organization and development of various medium-low speed maglev train test works. The cross sections of a left sleeperand a right sleeper are I-shaped, U-shaped plates with the contour being consistent with that of the left sleeper and the right sleeper are arranged on the two sides of the waist parts of the left sleeper and the right sleeper respectively, and the middle parts of the U-shaped plates are fixedly connected into a whole to clamp the left sleeper and the right sleeper. The bottom parts of the left sleeper and the right sleeper are located in transverse through grooves of a base steel plate, the lower part of the fastener system is fixedly connected with rail bearing platforms, and the upper partof the fastener system vertically buckles and presses the base steel plate and the U-shaped plates. A linear reciprocating motion mechanism acting on the left sleeper and the right sleeper to enable the left sleeper and the right sleeper to synchronously slide towards each other or away from each other transversely is arranged between the rail bearing platforms on the two sides.

Description

technical field [0001] The invention relates to a medium and low speed maglev rail transit system, in particular to a rapidly adjustable medium and low speed maglev variable gauge track structure. Background technique [0002] Gauge is an important parameter of medium and low speed maglev rail transit system, and it is an important basis for vehicle design and track line design. At present, there are mainly five gauge standards at home and abroad: 2000mm (Beijing S1 Line), 1900mm (Shanghai Lingang New City Low-speed Maglev Test Line), 1860mm (Changsha Maglev Express Line), 1850mm (Korean Incheon Airport Line), 1700mm (Japan Eastern Hills Line). [0003] In order to study the impact of different gauges on medium and low-speed maglev rail transit, and the vehicle factory needs to conduct relevant tests on the test line when the train is off the assembly line. If test lines with different gauge standards are constructed separately, the construction cost will be very high. Fo...
