Description

Technical Field

[0001] This application relates to the field of railway switches, and particularly to a sand baffle for railway switches. Background Art

[0002] A switch is a commonly used device in railway transportation, mainly used to control the direction of railway vehicle travel and the transformation of inbound and outbound line routes. Through the switch, trains from different directions can be adjusted to the appropriate tracks, thereby realizing the regulation of station traffic volume. The switch can control the travel direction of the train, thus avoiding collisions between vehicles and faults on the track, and ensuring the safety of the railway line. Through the flexible use of the switch, multiple lines can be used within a limited railway line, thereby improving the utilization rate of the railway line.

[0003] However, with the increase in train operating speed and transportation volume, the switch equipment faces a series of technical challenges. Especially when the locomotive brakes and decelerates passing through the switch, it is necessary to use a sand spraying system to spray sand grains, so as to increase the friction between the wheels and the rails, in order to achieve the purpose of rapid braking and deceleration. These sand grains may damage the locking mechanism of the switch and may also cause problems such as jamming of the external locking device of the switch, thus seriously affecting the normal use of the switch and reducing the operating efficiency and safety of the train.

Especially, the side protection plate and the baffle are made of rubber material, which avoids the hook forming an obstacle to the sand - blocking plate during installation, and further enhances the installation convenience of the sand - blocking plate.

[0016] 2. The sand - blocking plate of the present utility model is easy to install and has strong adaptability: The design of the sand - blocking plate fully considers the installation convenience. For example, the cooperation of the folding edge and the pressing plate on the main protection plate enables the side protection plate to be firmly pressed and fixed. At the same time, the rectangular notch design at one end of the main protection plate reduces the obstacle to the locking frame of the external locking device, making the installation easier. In addition, the sand - blocking plate can be applied to switches of different models and specifications, having strong adaptability.

[0017] 3.

[0024] The embodiment of this application discloses a sand baffle for railway turnouts. Referring to Figure 1 , a sand baffle for railway turnouts includes a main body protection plate 1, a baffle plate 2, two side protection plates 3 and two pressing plates 4.

[0025] On both sides of the main body protection plate 1 along the length direction, folding edges 11 perpendicular to the main body protection plate 1 are integrally provided. The two side protection plates 3 are located on both sides of the main body protection plate 1 along the length direction. The pressing plate 4 and the folding edge 11 cooperate to press and fix the side protection plate 3, and the pressing plate 4, the side protection plate 3 and the folding edge 11 are fixed by riveting.

[0026] One end of the main body protection plate 1 facing the stock rail 6 is provided with a rectangular notch 13. The main body protection plate 1 is fixedly connected with a baffle plate 2 by riveting at the rectangular notch 13, and the baffle plate 2 is a rubber plate. The rectangular notch 13 is provided to facilitate the installation of the sand baffle. The rectangular notch 13 can reduce the obstruction formed by the locking frame 8 of the outer locking device to the installation of the sand baffle during installation, and the baffle plate 2 is set as a flexible rubber plate to ensure that the sand baffle has a good sand blocking effect without affecting the installation.

[0027] Two square holes 12 are respectively opened on both sides of the main body protection plate 1 along the length direction. The square holes 12 are used to install the installation bolts of the outer locking device to fix the main body protection plate 1. The main body protection plate 1 is installed on the stock rail 6 and the bottom of the switch rail of the turnout. The side protection plate 3 is fixedly connected with the main body protection plate 1 to jointly form a space for accommodating the locking mechanism. The main body protection plate 1 is located on the locking rod 7 of the outer locking device, and the two side protection plates 3 are located on both sides of the locking rod 7 of the outer locking device.
