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, it is necessary to excavate the roadbed for replacement, which virtually increases the maintenance cost and maintenance difficulty; In addition, the slight wear and tear of the guard rail will affect the operation of the tram, so the replacement frequency of the guard rail is high, which increases the maintenance cost and difficulty

Embodiment 1

[0045] Such as figure 1 with figure 2 As shown, the first embodiment of the present invention proposes a turnout mechanism 1 , including: a basic rail 10 , a base 12 , a guard rail 14 and an eccentric sleeve 18 .

[0046] Specifically, the base 12 is located on one side of the basic rail 10, the guard rail 14 is installed on the basic rail 10 through a fastener 28, one side of the guard rail 14 fits the basic rail 10, and the guard rail 14 and the basic rail 10 Together, they form the track groove 16, that is, the rail flange groove, to ensure that the tram travels; the eccentric sleeve 18 is sleeved on the fastener 28, and can rotate inside the guard rail 14, thereby driving the guard rail 14 toward the side of the basic rail 10 sports.

[0047] Wherein, the eccentric sleeve 18 is sleeved on the fastener 28, so that the switch mechanism 1 has the function of replacing the guard rail, and when the guard rail 14 is worn or deviated, the guard rail 14 can be moved by rotating...

Embodiment 2

[0053] Such as figure 1 with figure 2 As shown, the second embodiment of the present invention proposes a turnout mechanism 1 , including: a basic rail 10 , a base 12 , a guard rail 14 and an eccentric sleeve 18 . Wherein, there is an adjustment gap 32 between the fastener 28 and the installation hole of the guard rail 14 .

[0054] Specifically, such as figure 2 As shown, there is an adjustment gap 32 between the fastener 28 and the mounting hole, and the adjustment gap 32 matches the eccentricity of the eccentric sleeve 18 to ensure that the eccentric sleeve 18 can rotate inside the guard rail 14 to adjust the installation of the guard rail 14. position, to ensure that the track groove 16 matches the tram.

[0055] Further, optional, such as image 3 with Figure 4 As shown, the distance between the center of rotation of the eccentric sleeve 18 and one end of the eccentric sleeve 18 is L1, and the distance between the center of rotation of the eccentric sleeve 18 and ...

Embodiment 3

[0059] Such as figure 1 with figure 2 As shown, the third embodiment of the present invention proposes a turnout mechanism 1 , including: a basic rail 10 , a base 12 , a guard rail 14 and an eccentric sleeve 18 . Wherein, the top of the guard rail 14 is recessed to form a receiving groove (not shown in the figure), and the top of the receiving groove is provided with a protective cover 20 .

[0060] Specifically, such as figure 2 As shown, a receiving groove is provided on the top of the guard rail 14, so that the end of the fastener 28 and the eccentric sleeve 18 are all located in the receiving groove; the top cover of the receiving groove is provided with a protective cover 20, and the protective cover 20 is located The top of the fastener 28 can avoid impurities such as dust falling in the groove, and at the same time prevent the fastener 28 from being exposed to the outside, which plays a certain protective role. Wherein, the protective sheath 20 also uses an eccentr...

Abstract

The invention provides a turnout mechanism and a track system. The turnout mechanism includes a basic rail, a base, a guard rail and eccentric sleeves, wherein the base is arranged on one side of thebasic rail, the guard rail is installed on the base through fasteners, and forms a track slot with the basic rail; and the eccentric sleeves sleeve the fasteners and can rotate on the fasteners to drive the guard rail to move towards one side of the basic rail. According to the turnout mechanism, functions of adjusting and replacing the guard rail are achieved. In the case of deviation or slight wear of the guard rail, the eccentric sleeve can be rotated to adjust the distance between the guard rail and the basic rail to ensure that the track slot is matched with a tram, in the case of seriouswear of the guard rail, the guard rail can be replaced to overcome the disadvantage that a related technology needs to excavate a subgrade to replace the guard rail, maintenance difficulty of the track system can be effectively lowered, and the maintenance cost and repair difficulty are greatly lowered.

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 frog of the tramway switch and the guard rail, and is an important part to ensure the safety 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 adjus...
