Abstract
Description
Technical Field
[0001] This utility model relates to the field of subway signal acquisition technology, and in particular to a subway signal turnout acquisition and monitoring device. Background Technology
[0002] Subways are high-speed, high-capacity, electrically powered rail transit systems built in cities. Trains run on fully enclosed tracks. Lines in the city center are mostly located in underground tunnels, while lines outside the city center are generally located on viaducts or at ground level. As one of the most important outdoor devices in the subway signaling system, the operation of turnout equipment directly affects the safety and efficiency of train operation. Therefore, subway signal turnout acquisition and monitoring devices are needed to collect and monitor turnout data.
[0003] The applicant discovered through a search that a Chinese patent, "A Subway Signal Turnout Acquisition and Monitoring Device," with publication (announcement) number "CN214948020U," mainly uses a shock-absorbing device between the device body and the switch machine to achieve a flexible connection, giving the device good shock absorption. However, the angle and position of the device body cannot be adjusted, which may lead to blind spots in the monitoring range. A fixed-angle monitor can only cover a specific area and cannot flexibly respond to different monitoring needs or changes. It may not be able to accurately target the specific location or object to be monitored, resulting in inaccurate data. The monitoring needs of subway turnouts may vary, and a fixed-angle monitor is inadequate and lacks flexibility when dealing with multi-functional monitoring or different tasks. Therefore, we propose a subway signal turnout acquisition and monitoring device. Utility Model Content

[0011] The technical effects and advantages of this utility model are as follows:
[0012] 1. Through the set adjustment structure, the motor drives the gear to rotate through the shaft, causing the gear to rotate on the half-tooth ring, thereby causing the angle of the fixed frame to deflect, and the angle of the monitor on the fixed frame to rotate. The mechanical cooperation between the gear and the half-tooth ring can provide good self-locking, avoiding unnecessary angle deviation of the fixed frame due to external force after the angle is adjusted, ensuring that the monitoring device can maintain a stable monitoring angle for a long time. The monitor can accurately align with the required monitoring area, avoiding the inconvenience of manual adjustment. It is especially practical in narrow or dangerous environments, especially in complex monitoring environments such as subway switches and tracks, ensuring that the monitor can capture key switch actions or signal changes, and can greatly reduce data distortion caused by improper angle.
[0013] 2. In the set installation structure, the slide plate slides in the second slide rail, and then the limit rod is inserted into the limit hole to limit the slide plate, so that the position of the monitor on the slide plate can be adjusted, and the monitor can move smoothly and linearly within the slide rail range. It is convenient to adjust the installation position of the monitor according to the specific conditions of different tracks or turnouts. By inserting the limit rod into the limit hole, the slide plate can be precisely limited, ensuring that the monitor is stable and does not move after being adjusted to the appropriate position.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Example 1:
[0024] Please see the appendix Figure 1 - Appendix Figure 4 A subway signal turnout acquisition and monitoring device includes a first fixed plate 1, with ear plates 11 fixedly installed around the first fixed plate 1. The first fixed plate 1 is provided with an adjustment structure 2 and a mounting structure 3. The mounting structure 3 is connected to the first fixed plate 1 through the adjustment structure 2. The adjustment structure 2 includes a semi-cylinder 21, a ring rail 22, a fixing frame 25, and a first slide rail 29. The semi-cylinder 21 is fixedly installed on one side of the first fixed plate 1, and the ring rail 22 is fixedly installed at both ends of the semi-cylinder 21. Openings are provided on the ring rail 22. The device has a first slide groove 24, a semi-tooth ring 23 fixedly installed in the middle of a semi-cylinder 21, a first slide rail 29 fixedly installed on the side of a fixed frame 25, the first slide rail 29 extending into the first slide groove 24 and slidably connected to the first slide groove 24, a rotating shaft 26 rotatably installed in the middle of the fixed frame 25, a gear 27 fixedly installed in the middle of the rotating shaft 26, the gear 27 meshing with the semi-tooth ring 23, and a motor 28 fixedly installed on the outside of the fixed frame 25, the motor shaft of the motor 28 being fixedly connected to one end of the rotating shaft 26.
[0025] Specifically, in the adjustment structure 2, the motor 28 drives the gear 27 to rotate on the semi-gear ring 23, causing the fixed frame 25 and the monitor to deflect at an angle. The mechanical engagement between the gear 27 and the semi-gear ring 23 has a self-locking property, ensuring the stability of the monitoring device and accurate alignment with the monitoring area. This avoids the inconvenience of manual adjustment and is suitable for use in complex environments such as subway switches. It ensures the capture of key motion changes, reduces data distortion, and improves monitoring accuracy.
[0026] Example 2:
[0027] Please see the appendix Figure 5 - Appendix Figure 7 The mounting structure 3 includes a mounting plate 301 and a sliding plate 304. The mounting plate 301 is fixedly mounted on one side of the fixing frame 25. A second slide rail 302 is symmetrically fixedly mounted on the mounting plate 301. Limiting holes 303 are symmetrically provided on both sides of the mounting plate 301. Slider blocks 305 are fixedly mounted on both sides of one end of the sliding plate 304. The sliders 305 are engaged with the second slide rail 302, and the sliding plate 304 is slidably connected to the second slide rail 302 via the sliders 305. A second fixing plate 306 is fixedly mounted on the upper and lower ends of the sliding plate 304. A screw 307 is threaded onto the second fixing plate 306. A clamping plate 309 is rotatably mounted on one end of the screw 307. Guide rods 308 are fixedly installed on both sides of rod 307. The guide rods 308 pass through the second fixed plate 306 and extend to the outside of the second fixed plate 306. The guide rods 308 are slidably connected to the second fixed plate 306. Fixed blocks 310 are fixedly installed on both sides of slide plate 304. Limiting rods 311 are slidably installed on the fixing blocks 310. The limiting rods 311 cooperate with the limiting holes 303. A connecting plate 312 is fixedly installed at the top of the limiting rods 311. A pull rod 313 is fixedly installed on the connecting plate 312. A spring 314 is sleeved on the limiting rods 311. One end of the spring 314 is fixedly connected to the connecting plate 312, and the other end of the spring 314 is fixedly connected to the fixing block 310.
[0028] Specifically, in the installation structure 3, the slide plate 304 slides in the second slide rail 302. The limit rod 311 is inserted into the limit hole 303 to limit the slide plate 304, thereby realizing the position adjustment of the monitor on the slide plate 304. The monitor can move smoothly and linearly within the range of the second slide rail 302, which is convenient for adjusting the position according to different tracks and turnouts. Inserting the limit rod 311 precisely limits the slide plate 304, ensuring that the monitor is stable after adjustment and improving the accuracy and reliability of monitoring.
[0029] Working principle: This utility model is a subway signal turnout acquisition and monitoring device. The first fixing plate 1 is fixed to the desired installation position via the ear plate 11. The monitor is placed on the sliding plate 304. Rotating the screw 307 moves the clamping plate 309, clamping the monitor. Pulling the pull rod 313 moves the connecting plate 312, causing the limiting rod 311 to slide within the fixing block 310. Simultaneously, stretching the spring 314 pushes the sliding plate 304, causing the slider 305 to slide on the second slide rail 302. When the sliding plate 304 moves to the appropriate position, it is released... When the pull rod 313 is opened, the connecting plate 312, under the elastic force of the spring 314, causes the limiting rod 311 to be inserted into the limiting hole 303, thereby limiting the slide plate 304 and fixing the slide plate 304 on the mounting plate 301. The motor 28 is started, and the motor shaft of the motor 28 drives the rotating shaft 26 to rotate. The rotating shaft 26 drives the gear 27 to rotate. Because of the meshing relationship between the gear 27 and the half-tooth ring 23, the gear 27 moves on the half-tooth ring 23, thereby causing the fixing frame 25 to drive the first slide rail 29 to slide in the first slide groove 24, thereby adjusting the angle of the fixing frame 25. The fixing frame 25 drives the mounting plate 301 to rotate, and the mounting plate 301 drives the angle adjustment of the monitor.
[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
