Problems solved by technology

[0006] (1) The way to adjust the gauge of the existing fastener system is often achieved by replacing the gauge baffles (or gauge blocks) of different specifications and models. This method not only results in higher production and design costs for the fastener system, but also Moreover, the maintenance and repair workload of the fastener system is large, the replacement work is complicated, and it is easy to make mistakes;
[0007] (2) The existing fastener system generally does not have an anti-overturning design for the rail, and there are certain hidden dangers in the driving safety of the tram;
[0008] (3) The existing fastener system has a large number of parts and complex structure combination, and the cost of on-site installation and maintenance is high, which is not conducive to shortening the construction period of the rail transit system

Embodiment

[0055]The tram fastener system in the preferred embodiment of the present invention is such asFigure 1~10 Shown in. It includes a track fixing component and a gauge adjustment component. Through the corresponding cooperation of the two components, accurate positioning of the lateral position of the rail 6 and rapid adjustment of the gauge of the rail 6 can be realized.

[0056]Specifically, in a preferred embodiment, the gauge adjustment component of the fastener system includes a gauge adjustment plate 1, a gauge baffle 2 and a sleeper 3 arranged in a corresponding combination. Among them, the combined arrangement of the gauge adjusting plate 1 and the gauge baffle 2 forms a gauge adjusting unit, and the gauge adjusting unit is separately arranged on two lateral sides of the steel rail 6, that is, the gauge adjusting unit is arranged in pairs.

[0057]Further, the gauge adjustment plate 1 in the preferred embodiment is asFigure 4 ,5As shown in the figure, it is a wedge-shaped structure w...

Abstract

The invention discloses a tramcar fastener system, and belongs to the technical field of track fasteners; track gauge adjusting components consisting of track gauge baffles and track gauge adjusting plates are arranged on two sides of a steel rail, and first matching parts on the track gauge adjusting plates are correspondingly matched with second matching parts on the track gauge baffles; and a double-inclined-plane coupling structure is formed between the track gauge adjusting assembly and a blocking shoulder of a sleeper, and reliable arrangement of the tramcar track system and rapid adjustment of the track gauge of the steel rail can be achieved. The tramcar fastener system is simple in structure, easy and convenient to arrange and adjust and low in maintenance difficulty, rapid adjustment of the rail gauge is effectively achieved, the stability of the arranged steel rail and the flexibility of rail gauge adjustment are guaranteed, and the safety and stability of tramcar rail system arrangement are guaranteed; and the development of a tramcar rail transit system is promoted, and good application prospects and popularization value are achieved.

Description

Technical field[0001]The invention belongs to the technical field of rail fasteners, and specifically relates to a tram fastener system.Background technique[0002]With the rapid development of society and the significant improvement of people's living standards, people have put forward higher requirements for travel, which has also strongly promoted the rapid development of the transportation industry. Among the many forms of urban rail transit, the new tram is a new form of urban rail transit with low investment cost and short construction period. It has already played a very important role in the transportation construction of a large number of cities.[0003]In rail transit, the fastener system is an indispensable important part. Its role is to fix the position of the rail, prevent the rail from longitudinal and lateral displacement, prevent the rail from overturning, and at the same time provide the necessary elasticity and insulation properties. For trams, the fastener system shou...
