Description

Technical Field

[0001] This invention relates to a signal used on railways, and more particularly to a through signal that displays forward and reverse directions on the same line within a section. Background Technology

[0002] In recent years, more and more new railway lines have been built. In order to meet the needs of operating speed, the new lines are usually double-tracked and bidirectional automatic block signaling. Each line is automatically blocked between stations when traveling in the opposite direction.

[0003] Single-track railways use automatic block signaling for both directions. As speed requirements on single-track railways increase, some lines have installed signals on both sides to achieve automatic block signaling for both directions. However, this increases equipment and construction costs. On double-track railways, the distance between the two tracks is smaller, making it very difficult to install signals on both sides of either track simultaneously.

[0004] Currently, the signals used on railways are color light signals, which indicate signals by the color, number, and illumination status of lights. Color light signals are divided into searchlight type, lens type, combination type, and LED type. Searchlight type color light signals have long been discontinued and are no longer in use; combination type signals are less commonly used in the field; lens type signals are the most widely used; while LED color light signals have a long display distance, long lifespan, and are safe and reliable, making them an energy-saving and maintenance-free new type of signal. However, regardless of the type of color light signal, they only provide a signal in one direction; when trains are traveling in the opposite direction, they cannot provide a signal.

[0005] In view of the above, a signal that can display both forward and reverse directions on the same line has many advantages. This signal can provide signal display from both directions, so that automatic blocking is performed regardless of whether the operation is in the forward or reverse direction on the same line, while also saving costs. Summary of the Invention

[0006] The purpose of this invention is to provide signal lights to direct train operation on the same line, regardless of whether the train is traveling in the forward or reverse direction, ensuring that the block system for both directions on the same line is automatic block signaling. For existing single-track railways, both directions use automatic block signaling between stations. Using the signals of this invention can achieve automatic block signaling for both directions. For existing double-track railways, each line uses automatic block signaling for forward travel and automatic block signaling between stations for reverse travel. If automatic block signaling is required for reverse travel, it can only rely on onboard signals, as there are no ground signals to rely on, resulting in poor safety. If each line of a double-track railway uses the signals of this invention, then each line can achieve automatic block signaling based on ground signals regardless of the direction of travel.

[0007] This invention provides a section passing signal that can be used on both single-track and double-track railways. The signal structure includes a pole, a signal mechanism, a signal clamp, a ladder, a ladder base, a ladder clamp, a chuck, and a flexible tube. The signal mechanism is a three-light mechanism, comprising green, red, and yellow lights from top to bottom. The clamp secures the signal mechanism to the pole. To provide signal lights for both forward and reverse traffic, two three-light mechanisms need to be installed on the signal pole. These two three-light mechanisms can use XSL-type LED color light signals. After using the LED signal mechanism, the LED railway color light signal mechanism is the same size as the lens-type color light signal mechanism, and using the LED color light signal mechanism does not require changing the existing signal lighting circuit.

[0008] Installing two three-lamp mechanisms requires four signal clamps, such as Figure 3 As shown. In Figure 3 In this configuration, the four clamps are staggered, effectively securing the two three-lamp mechanisms at the same height. Furthermore, using four clamps facilitates the installation of the signal mechanism. The signal clamp consists of two parts: a bracket and U-bolts. The dimensions of the bracket and U-bolts are as follows... Figure 6 As shown, there is one hole with a diameter of 1.7cm on the bracket for connecting to the three-light mechanism. One three-light mechanism has three signal lights, corresponding to three main units. The three-light mechanism also includes components such as canopies, bolt sets, and support bases. The support base has a hole with a diameter of 1.7cm. The specific method of fixing the three-light mechanism with the signal clamps is as follows: there is a support base on the uppermost main unit; align the hole on the support base with the hole on the bracket, and then connect and fix it using the bolt set. Similarly, there is also a support base under the lowermost main unit; align the hole on the support base with the hole on the bracket, and then connect and fix it using the bolt set. Therefore, one three-light mechanism requires two signal clamps for fixing, and two three-light mechanisms require four signal clamps for fixing.

[0009] Railway color light signals also require a ladder for maintenance work. In this invention, the ladder is positioned to the left of the three-light mechanism used for forward traffic, i.e., on the side furthest from the railway line, such as... Figure 1 As shown. Because the two three-light mechanisms are positioned "back-to-back," and the ladder is on the left side (away from the railway line) of the three-light mechanism used for forward traffic, maintenance personnel need to work sideways when simultaneously repairing both mechanisms. However, considering the limited maintenance work on the signal poles, placing the ladder on the side away from the railway line also meets the needs of maintenance personnel. The ladder's clamps consist of two semi-circular bolts and two brackets. The two semi-circular bolts need to be interlocked, such as... Figure 8As shown. While securing the two semi-circular bolts with the bolt group, the shorter end of the bracket can also be fixed simultaneously. The leftmost ends of the two brackets need to be connected and fixed to the ladder, which can be done by welding. The final connection between the ladder and the signal post is as follows. Figure 9 As shown. Furthermore, the length of the ladder brackets varies from top to bottom; the specific lengths are already shown. Figure 9 The information is provided in the text.

[0024] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will now be described more fully with reference to the accompanying drawings. Preferred embodiments of the present invention are shown in the drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of the present invention.

[0025] like Figure 4 The diagram illustrates an embodiment of the invention on a single-track railway. Figure 4 On the railway line shown, signals indicating the forward and reverse directions are placed at the boundary points. First, the signal post is installed on the left side of the line, at the same height as the existing through signal for the section. Next, the signal mechanism is installed; two three-light mechanisms are secured by four clamps, which are staggered to ensure the two three-light mechanisms are fixed at the same height on the post. Finally, a ladder for signal maintenance is installed outside the line. In this way, the signal is... Figure 4 The signal has been installed on the single-track railway shown. This signal meets the needs for both forward and reverse traffic, enabling automatic block signaling for both directions on this single-track railway.

[0026] like Figure 5 The diagram illustrates an embodiment of the invention on a double-track railway. Figure 5 On the railway line shown, signals indicating the forward and reverse directions are placed on the outer sides of both tracks. The implementation steps are the same as those for a single-track railway. Figure 5 Once the signal lights are arranged on the line shown, automatic block signaling can be achieved on each track of the double-track railway regardless of the direction of travel. Additionally, when... Figure 5 When one track of the double-track railway shown malfunctions and cannot be opened normally, automatic block signaling can still be implemented on the other track for both forward and reverse directions.

[0027] Taking the implementation method on a single-track railway as an example, the signal of the present invention can also be designed with a lighting circuit. First, the track relay excitation circuit is designed, which can use conditions to excite the same group of track relays in different running directions to realize the occupancy check of the track section, such as... Figure 10 As shown.

[0028] Next, a repeater relay for the track relay needs to be added. Considering that there is only one track relay per track section, but the signal has added three lights for reverse operation, there might be insufficient track relay contacts in the lighting circuit. Therefore, to achieve the desired lighting circuit design, a repeater relay for the track relay needs to be added, so that the contacts of the repeater relay can be used to control the three lights for reverse operation. For example... Figure 11 As shown, a repeater relay has been added to each track relay.

[0029] It is also necessary to add repeating relays for the forward and reverse direction relays of the section. In the lighting circuit, it is also necessary to consider that when the train is running in the forward direction, the three lights controlling reverse train movement are in the off state; and when the train is running in the reverse direction, the three lights controlling forward train movement are in the off state. To achieve this, the contacts of the forward and reverse direction relays of the section should be added to the lighting circuit. Similarly, considering the possibility that the contacts of the forward and reverse direction relays of the section are insufficient, repeating relays for the forward and reverse direction relays of the section should be added, such as... Figure 12 As shown. In the lighting circuit for the three lamp positions that direct trains to run in the opposite direction, a repeating relay with forward and reverse direction relays is used uniformly.

[0030] Therefore, taking the implementation method on a single-track railway as an example, for signal 0043, the lighting circuit for the three-lamp position that directs the train to move forward is as follows: Figure 13 As shown. The lighting circuit for the three lamp positions that direct the train to run in reverse is as follows. Figure 14 As shown.
