Embodiment Construction

[0036] Exemplary embodiments, features and aspects of the present invention will be described in detail below with reference to the accompanying drawings. The same reference numbers in the figures denote elements that have the same or similar functions. While various aspects of the embodiments are shown in the drawings, the drawings are not necessarily drawn to scale unless otherwise indicated.

[0037] Specifically, the present invention provides a new type of switch system that can eliminate harmful spaces for driving, such as figure 1 As shown, it includes a movable track 1, a bearing turntable 2, a turntable fastener 3, a self-locking support 4, a fork center backing plate 5, a fork center guard rail 6, a sliding plate 7 and a general track member.

[0038] like figure 2 As shown, the movable rail 1 includes a movable curved rail 101 and a movable straight rail 102. The movable curved rail 101 and the movable straight rail 102 are combined into an integral frame by conn...

Abstract

The invention provides a turnout system, which includes a movable track, a carrying turntable, a fastener for the carrying turntable, a self-locking support, a center backing plate, a center guard rail and a sliding plate. Among them, the movable track is a track that integrates the point rail, the guide rail, and the wing rail, and can move under the action of the switch machine. The bearing turntable is fastened on the turnout sleeper through threaded spikes, and the movable track is installed on the bearing turntable with fasteners to realize rotation around a fixed point. And it is equipped with self-locking support to ensure the stable operation of the movable curved rail; the fork center guard rail and the frog center are combined as a whole to guide the wheels to avoid collision and derailment and limit the limit position of the movable track; the fork center pad is used for installation Fork center assembly, the body is installed on the switch sleeper; the sliding plate provides support for the movable track to prevent jumping and deformation. The invention not only can effectively eliminate the harmful space of the turnout, but also simplifies the scheduling operation, reduces the possibility of wrong scheduling, and improves the scheduling efficiency.

Description

technical field [0001] The invention relates to the field of railway tracks, in particular to a switch system. Background technique [0002] With the development of my country's railway system and the continuous improvement of train speed, turnouts are used more and more widely as an important equipment to realize track switching in railway dispatching systems. However, in the working process of the switch, there is always a harmful space at the throat of the frog, that is, when the wheel passes through the frog, there is a gap between the narrowest part of the two wing rails and the tip of the frog core. When the wheels pass here, guard rails are provided, which can forcefully guide the running direction of the wheels due to the possibility of derailment due to the wrong frog groove. Nevertheless, the existence of harmful space still limits the speed of the train passing the switch, which is very unfavorable for the operation of high-speed trains. To solve the harmful spa...
