Problems solved by technology

At present, the guard rails of trams generally adopt integral alloy steel guard rails or surfacing welded guard rails, which are disposable parts and cannot be replaced
After the guard rail is worn out, it cannot be replaced or adjusted, and the overall operation status of the turnout mechanism cannot be guaranteed, which brings inconvenience to the maintenance of the works; after the guard rail is scrapped, the subgrade needs to be excavated for replacement, which virtually increases the maintenance cost and difficulty

Embodiment 1

[0043] Such as figure 1 As shown, the first embodiment of the present invention proposes a turnout mechanism 1 , including: a basic rail 12 , a mounting part 14 and a guard rail 16 .

[0044] Specifically, such as figure 2As shown, the basic rail 12 and the mounting part 14 are all arranged on the backing plate 10, the guard rail 16 is arranged on the mounting part 14, one side of the guard rail 16 is attached to the basic rail 12, and the guard rail 16 and the basic rail 12 are in common Constituted track groove 18, guarantees tram to advance.

[0045] Wherein, the installation part 14 installs the guard rail 16, avoids the casting installation method of the guard rail 16 in the related art, and can ensure the installation strength of the guard rail 16, and avoids the direct connection of the guard rail 16 and the basic rail 12 to the basic rail 12 in the related art. damage; the guard rail 16 and the mounting part 14 are detachably connected, and when the guard rail 16 we...

Embodiment 2

[0048] Such as figure 1 As shown, the second embodiment of the present invention provides a turnout mechanism 1 , including: a basic rail 12 , a mounting part 14 and a guard rail 16 , wherein the mounting part 14 includes a platform 142 and a base 144 .

[0049] Specifically, such as figure 2 As shown, the base plate 142 is arranged on the backing plate 10, and the base 144 is positioned above the base plate 142; figure 2 The position shown in the middle guard rail 16) and the contact portion 146. The guard rail 16 is arranged in the installation space, the top of the mounting part 14 is in contact with the bottom wall of the guard rail 16, and a supporting force is given to the guard rail 16 in the vertical direction; the contact portion 146 is in contact with the side wall of the guard rail 16 Fitting, a limit is given to the guard rail 16 in the horizontal direction.

[0050] Such as figure 2 As shown, the base 144 has an L-shaped structure as a whole, so that the in...

Embodiment 3

[0058] Such as figure 1 As shown, the third embodiment of the present invention proposes a track system (not shown in the figure), including the switch mechanism 1 of any of the above-mentioned technical solutions, therefore, based on all the beneficial effects of the above-mentioned switch mechanism 1, no Discuss them one by one.

[0059] Specifically, the track system is a track system for a tram, and the tram can run on the track system.

Abstract

The invention provides a turnout mechanism and a rail system. The turnout mechanism comprises a base plate, a stock rail arranged on the base plate, an installing part arranged on the base plate and located on one side of the stock rail, a protection rail detachably arranged on the installing part and forming a rail groove together with the stock rail. According to the turnout mechanism, the protection rail is detachably installed on the installing part, so the whole turnout mechanism has a function of replacing the protection rail; the protection rail can be directly replaced when abraded, the defect that a roadbed needs to be dug when a protection rail is replaced in the prior art is avoided, the maintenance difficulty of the rail system can be effectively reduced, and the maintenance cost and maintenance difficulty are greatly reduced.

Description

technical field [0001] The invention relates to the technical field of urban rail transit, in particular to a turnout mechanism and a rail system. Background technique [0002] In recent years, there has been an upsurge of trams around the world. More than 50 countries and more than 400 cities are operating trams, and foreign countries are constantly upgrading traditional trams or building new tram lines. In China, modern trams have also been valued and developed. There are at least hundreds of tram lines in the country under planning, with a total mileage of more than 6,000 kilometers. [0003] The guard rail is an important part of the turnout mechanism of the tram, and is an important part to ensure the safe crossing of the train. At present, the guard rails of trams generally adopt integral alloy steel guard rails or surfacing welded guard rails, which are disposable parts and cannot be replaced. After the guard rail is worn out, it cannot be replaced or adjusted, and ...
