Embodiment Construction

[0027] The tramway fastener of the present invention is a non-separate type fastener with shoulder elasticity, such as figure 1 As shown, including: embedded sleeve 1, gauge baffle plate 2, gauge block 3, plastic pad 4, elastic bar 5, square gasket 6, spiral spike 7, rubber pad 8, under-rail height adjustment pad 9. Adjust the backing plate 10 as a whole.

[0028] Such as figure 2 As shown, the embedded casing 1: the material is glass fiber reinforced polyamide 66, which is embedded in the concrete sleeper, and the casing has internal threads to cooperate with the spiral spike 7.

[0029] Such as image 3 As shown, the gauge baffle 2: the material is glass fiber reinforced polyamide 66, and the sides of the gauge baffle are respectively in contact with the sleeper shoulder and the gauge block 3, which are used to ensure the position of the rail and transmit the lateral force of the rail to the sleeper . The gauge baffle is provided with a position for laying the elastic b...

Abstract

The invention discloses a tramcar rail fastener. The tramcar rail fastener comprises an embedded sleeve, a gauge apron, an elastic strip and a screw spike, wherein the embedded sleeve is embedded in aconcrete sleeper, the gauge apron is installed on the two sides of a rail bearing groove of the concrete sleeper, the inclined face of the gauge apron is tightly attached to the inclined face of therail bearing groove, and a round hole of the gauge apron is aligned with a round hole of the embedded sleeve; a rubber base plate is placed on the concrete sleeper, and a steel rail is placed on the rubber base plate; a gauge block is installed between the gauge apron and the steel rail, and a plastic pad is installed in a groove of the gauge block; the tail end of the elastic strip is installed on the gauge apron, and the front end of the elastic strip is pressed on the plastic pad; and the screw spike penetrates through the round hole of the gauge apron and is screwed into the embedded sleeve to press the elastic strip and the steel rail. Compared with like products in the prior art, the tramcar track fastener can provide enough buckling pressure, vibration reduction performance and insulation performance for a track, and it can be guaranteed that the steel rail has enough track gauge adjustment amount and height adjustment amount.

Description

technical field [0001] The invention relates to a rail fastener for a tram. Background technique [0002] With the development of urban rail transit, trams can be rapidly promoted and used due to their advantages of energy saving and environmental protection. The tram fastener is one of the important components of the tram project. Its main function is to fix the rail, keep the rail at a fixed gauge, and provide sufficient damping performance and insulation performance for the rail system. [0003] At present, existing tram fasteners have disadvantages such as complex structure, poor ability to adjust height or distance, or poor insulation performance. Contents of the invention [0004] In order to overcome the above-mentioned shortcomings of the prior art, the present invention proposes a rail fastener for a tram. [0005] The technical solution adopted by the present invention to solve the technical problem is: a tram rail fastener, including a pre-embedded sleeve, a g...
