Embodiment

[0027] Embodiment: A low-maintenance medium-low speed maglev three-dimensional adjustable fastener, comprising H-shaped sleepers 13, iron backing plates 5, and rail platforms 12 arranged from top to bottom. The H-shaped sleepers 13 have two bottom plates on both sides. An oblong hole 13A is provided. The iron backing plate 5 is provided with a first bolt connection hole 5C and a second bolt connection hole 5D. The H-shaped sleeper 13 is screwed into the oblong hole 13A by a T-bolt 7 and is connected to the first bolt. The hole 5C is connected to the iron backing plate 5. The iron backing plate 5 is connected to the rail support 12 by screwing the anchor bolt 1 into the second bolt connection hole 5D, and the first bolt connection hole 5C includes a T-bolt screw-in hole 5A And T-bolt locking hole 5B, the T-bolt screw-in hole 5A is located above the T-bolt locking hole 5B. The connecting portion of the T-bolt 7 and the H-shaped sleeper 13 is provided with a damping washer 9 and a...

Abstract

The invention discloses a low-maintenance low-and-middle-speed magnetic suspension three-dimensional adjustable fastener. The low-maintenance low-and-middle-speed magnetic suspension three-dimensional adjustable fastener sequentially comprises an H-shaped sleeper, an iron cushion plate and a rail supporting table from top to bottom, wherein oblong holes are respectively formed in bottom plates of two sides of the H-shaped sleeper; the iron cushion plate is provided with a first bolt connecting hole and a second bolt connecting hole; the H-shaped sleeper is screwed in the oblong holes and the first bolt connecting hole through T-shaped bolts and is connected with the iron cushion plate; the iron cushion plate is screwed in the second bolt connecting hole through an anchoring bolt and is connected with the rail supporting table; the first bolt connecting hole comprises a T-shaped bolt screwing-in hole and a T-shaped bolt locking hole; and the T-shaped bolt screwing-in hole is positioned above the T-shaped bolt locking hole. The oblong holes are formed in the H-shaped sleeper, so that lines along a rail row can be adjusted in the longitudinal direction, notches are formed in the iron cushion plate and the H-shaped sleeper, the rail row can be adjusted and limited in the transverse direction, and vertical large-range heightening can be implemented through a combination of different heightening cushion plates.

Description

technical field [0001] The invention relates to the technical field of maglev tracks, in particular to a low-maintenance, medium-low speed maglev three-dimensional adjustable fastener. Background technique [0002] Medium and low-speed maglev transportation has the characteristics of low vibration, low noise, fast acceleration, strong ability to climb slopes and curves, and can well overcome the shortcomings of wheel-rail transportation. It has obvious technical and economic advantages and is a green urban rail transportation in the 21st century. One of the important directions of development. [0003] The medium and low speed maglev is a constant conduction magnetic suction maglev system. The electric field is generated by the suspension electromagnet placed on the bogie, which makes the magnet and the ferromagnetic components on the track attract each other, suspends the train on the track, and the maglev vehicle passes through the track on the track. The sensors and cont...
