Modern tram trough type steel rail fastener

Abstract

The invention discloses a modern tram trough type steel rail fastener which comprises a steel rail, a base plate, a bolster below the rail, two gauge blocks, two screw spikes, two elastic strips, two lock washers, an embedded sleeve, a heightening bolster below the rail, a heightening bolster below the plate and a sleeper. The embedded sleeve is arranged below the sleeper, the base plate is located on the sleeper, the heightening bolster below the plate is located on the base plate, the heightening bolster below the rail is located on the heightening bolster below the plate, the steel rail is located on the heightening bolster below the rail, the gauge blocks are arranged on the two sides of the steel rail, the elastic strips are located between the gauge blocks and the base plate, and the screw spikes fix the elastic strips through the lock washers. Compared with the prior art, the fastener system is matched with the trough type steel rail, enough fastening force is provided, it is ensured that the trough type rail and the concrete short sleeper with a retaining shoulder is reliably and stably linked, the number of parts is small, university is good, the structure is simple, and installation is convenient.

Description

technical field [0001] The invention relates to a traffic equipment component, in particular to a grooved steel rail fastener for a modern tram. Background technique [0002] The construction cost of modern tram is low, the cycle is short, and the transportation capacity is between the subway and the conventional bus. It can be used as an encrypted line of the existing rail transit in a large city, and can also be used as an extension of the subway, light rail and other rail transit lines in the suburbs. The feeder line can also be used as a satellite city (new town) around a large city and a public transportation backbone in a small and medium-sized city, becoming an important part of the urban public transportation system. In recent years, modern trams have been used in Dalian, Shenyang, Suzhou, Tianjin And other cities have been applied, and other cities are also vigorously developing and promoting applications. [0003] Modern tram rails adopt grooved rails, and the inc...

Problems solved by technology

Therefore, the fastener system of modern trams cannot directly use the track components of the original national railway or subway

[0004] Since the running speed of urban trams is lower than 80km / h, and the rail fasteners are buried in the road in the shared right-of-way section, the existing subway or low-grade railway line rail fastener systems are used to fix the trams Rail rails, which can easily cause system mismatch and waste of materials. More importantly, the components of the fasteners are mostly iron or cast iron parts. There are no protective measures after being buried underground, which is easy to rust and corrode, which is not convenient for future track maintenance. repair

The development of modern trams in foreign countries has been relatively mature and has corresponding supporting track systems, but its buckle fittings system has monopolized the tram market, and the price is high, which is not conducive to promoting the development of the tram track system industry.
