Problems solved by technology

Using this kind of mechanical joint as a connecting piece will inevitably form a gap d at the joint, and the splicing surface will not be aligned due to errors in parts manufacturing and construction, resulting in vehicle current collectors (also known as collector shoes) The friction surface between the contact rail and the contact rail is not smooth, which affects the flow quality of the vehicle
[0003] Even if during the construction process, the joints are treated by replacing parts and grinding the joints, the smoothness requirements can be met temporarily, but usually the rail temperature changes in a large range, and in the operating environment of long-term frequent vibrations, the fast

Abstract

The invention discloses a seamless contact rail system and a connecting method of the contact rail system. The seamless contact rail system comprises multiple anchoring sections arranged in the line direction; each anchoring section comprises at least two current-carrying parts with current-carrying demands; and the two adjacent current-carrying parts are seamlessly connected with each other. According to the technical scheme of the embodiment of the invention, the use of a mechanical joint is avoided, and the operation workload is reduced. The integrity and smoothness of a contact rail are also improved, the dynamic characteristic between a collector shoe and the contact rail is improved, and the system and the method are beneficial for improving the current supplying quality and enhancing the adaptability to higher speed target value.

Description

technical field [0001] The invention relates to a contact rail system of rail transit, in particular to a seamless contact rail system and a connecting method of the contact rail system. Background technique [0002] Taking the connection of two adjacent contact rails as an example, along the line extension direction, two adjacent contact rails a are connected by mechanical joints, such as figure 1 As shown, the mechanical joint includes a fishplate b and a fastener c, and the fastener is generally a bolt. Using this kind of mechanical joint as a connecting piece will inevitably form a gap d at the joint, and the splicing surface will not be aligned due to errors in parts manufacturing and construction, resulting in vehicle current collectors (also known as collector shoes) The friction surface between the contact rail and the contact rail is not smooth, which affects the flow quality of the vehicle. [0003] Even if during the construction process, the joints are treated ...
