Elastic separate fastener for medium and low speed maglev track

Abstract

An elastic split type fastener of a medium and low speed magnetic suspension rail has enough strength and buckling pressure, has large rail vertical, transverse and longitudinal adjusting capacity simultaneously provides rail elasticity and achieves bidirectional vibration attenuation. The elastic split type fastener comprises two groups of connection bolt assemblies arranged transversely at intervals and two groups of anchoring bolt assemblies transversely arranged at intervals, wherein the connection bolt assemblies integrate an H-shaped steel pillow with a connection board, vibration attenuation gaskets are arranged on the contact surfaces of the connection bolt assemblies and the H-shaped steel pillow, an under-pillow elastic cushion plate is arranged between a base plate of the H-shaped steel pillow and the connection board, and connection bolt long round holes extending along the circuit direction and used for enabling the upper portions of the connection bolt assemblies to penetrate through are arranged on the bottoms on two sides of the H-shaped steel pillow; and the anchoring bolt assemblies integrate the connection board and a support rail table, the lower portions of the anchoring bolt assemblies are connected with the support rail table in anchoring mode, a buffering cushion plate is arranged between the connection board and an iron cushion plate at the top surface of the support rail table, and anchoring bolt long round holes extending along the direction perpendicular to the circuit and used for enabling the upper portions of the anchoring bolt assemblies to penetrate through are arranged on the connection board.

Description

technical field [0001] The invention relates to the field of maglev rails, in particular to an elastically separate fastener for a medium-low speed maglev rail and a rail support structure for connecting a row of medium-low speed maglev rails and a rail support structure and an adjustment method thereof. Background technique [0002] Medium and low-speed maglev transportation has the characteristics of strong climbing ability, small turning radius, strong line adaptability, low noise, small vibration, energy saving and environmental protection, beautifying the urban environment, low construction cost, and easy implementation. It is suitable for urban areas and close-distance cities It is a safe, reliable and environment-friendly new urban rail transit system. [0003] Medium and low-speed maglev is an attraction maglev system under constant guidance. It uses the levitation electromagnet placed under the guide rail on the vehicle to energize and excite to generate an electric...

AI Technical Summary

Problems solved by technology

(2) The rail row of medium and low speed maglev transit can be regarded as an overall structure, which is firmly connected and has large longitudinal and lateral rigidity, so it does not need to be considered and does not have the feasibility of gauge adjustment

This technology directly connects the fastener screw with the support frame pre-buried in the track beam body by welding, which is a non-separate fastening method; although the fastener is firmly connected and has high reliability, it also has poor vertical and horizontal adjustment capabilities of the rail row. And failed to solve the problem of two-way vibration reduction
