Freeze and shock proof turnout

Abstract

The invention relates to a freeze and shock proof turnout which comprises a base, a ram, a straightaway transition rail, a turnout transition rail, a drive device and a ram locking device, wherein the straightaway transition rail and the turnout transition rail are arranged on the ram. The freeze and shock proof turnout is characterized in that the straightaway transition rail and the turnout transition rail which are arranged on the ram in parallel move on the base through the ram to finish turnout conversion, and the ram is locked through a positioning device. The freeze and shock proof turnout has the advantages that because the connection between the transition rails and steel rail joints at both ends of the transition rails is smooth and has small gaps, clearance spaces in medium and low speed turnouts at present are eliminated; a high-strength precise positioning and locking device is adopted, which ensures that a train is stable and safe during passing the turnout, and impact shocks and noise between wheels and rails are greatly reduced, thus the train can quickly and safely pass the turnout without reducing the speed; and meanwhile, the drive device is arranged in the ram to thoroughly eliminate influences caused by snow and ice in winter on the turnout, thus a snow and ice thawing device does not need to be arranged in the turnout so as to reduce the investment, save energy and protect the environment. The freeze and shock proof turnout is widely applied to medium and low speed railways and urban metro and light rail routes.

Description

technical field [0001] The invention relates to a turnout device used on a railway track line, in particular to an antifreeze and shockproof railway safety turnout. Background technique [0002] At present, moveable turnouts are commonly used on railways, and the switch is realized by moving the switch rail between the straight track and the switch track. In winter, when snow accumulates, it is very easy to cause ice between the switch rail and the basic rail, resulting in improper movement of the switch rail. , so that the turnout function fails to cause accidents; the current solution is to install electric heating devices on the switch rail and the basic rail to melt the ice, which not only requires a large investment, but also consumes a lot of energy. In addition, in the current medium and low-speed turnouts, there are still harmful spaces such as turnout ditch, and the train has to slow down when passing the turnout, which restricts the running speed of the train when ...

[0002] At present, moveable turnouts are commonly used on railways, and the switch is realized by moving the switch rail between the straight track and the switch track. In winter, when snow accumulates, it is very easy to cause ice between the switch rail and the basic rail, resulting in improper movement of the switch rail. , so that the turnout function fails to cause accidents; the current solution is to install electric heating devices on the switch rail and the basic rail to melt the ice, which not only requires a large investment, but also consumes a lot of energy

In addition, in the current medium and low-speed turnouts, there are still harmful spaces such as turnout ditch, and the train has to slow down when passing the turnout, which restricts the running speed of the train when passing the turnout. At the same time, it generates large vibration and noise, and the maintenance cost of the turnout is high.
