Problems solved by technology

[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 rai

Example Embodiment

[0028] Example 1:

[0029] figure 1 As shown in the figure, the base 3 on one side of the ram 4 is provided with a straight rail, and the other side is provided with a straight rail 1 and a switch rail 2 at the same time; the ram 4 provided on the base 3 is simultaneously provided with a straight transition rail 6 and a switch rail Transition rail 7; the motor 8 and screw 9 of the ram driving device are arranged in the internal space of the ram (see diagram 2-1 ), one end of the screw is located in the thread fixed in the boss 10 on the base, and the other end of the screw is connected to the motor shaft or the motor decelerating device. The driving device is controlled by the travel switch or pressure sensor on the ram or the boss. stroke.

[0030] image 3 As shown in the figure, both ends of the straight transition rail 6 and the divergence transition rail 7 arranged side by side on the ram are fixedly installed on the ram, while the straight transition rail and the divergence ...

[0037] Example 2

[0038] Figure 5 As shown, a positioning device is provided between the ram 3 and the base 4. The positioning device is composed of a positioning sleeve 13, a positioning sliding shaft 14, a sliding shaft sleeve 15 and a driving device, and the sliding shaft in the positioning sleeve or located in the positioning sleeve The outer end of 14 is equipped with a travel switch or pressure sensor that controls the operation of the sliding shaft. In the sliding sleeve or the inner end of the sliding shaft in the sliding sleeve, there is a travel switch or pressure sensor that controls the return stroke of the sliding shaft; in the sliding sleeve 15 or at the inner end of the sliding shaft in the sliding sleeve, there is also Pressure sensor that controls the ram drive.

[0039] In application, when the traffic state of the turnout needs to be changed, the driving device power supply in the positioning device is turned on in the reverse direction, and the sliding shaft ...

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 ...
