Abstract
Description
Technical Field
[0001] This utility model relates to the field of railway inspection technology, and in particular to an integrated inspection structure for railway TFDS and TWDS systems. Background Technology
[0002] Both TFDS and TWDS are core equipment in the railway 5T inspection system, mainly used for the safety inspection of freight cars. The TFDS system collects images of the bottom of the vehicle and focuses on inspecting the lower and outer parts of the components. The TWDS online inspection system uses laser sensors installed on both sides of the track to perform non-contact automatic measurement of the wheel hub geometry parameters of the rail vehicle.
[0003] Currently, TWDS relies on CCD cameras to capture wheel conditions, requiring precise angular matching between the light and the key detection area of the wheel. However, in existing technologies, the CCD cameras used for wheel detection are installed at a fixed angle and cannot be adjusted. After long-term operation, the track is prone to local settlement, and the fixed angle of the CCD camera will cause its relative height to deviate from the design benchmark, resulting in distortion of some wheel parameters and affecting the accuracy of the measurement. In view of this, this utility model is proposed. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0027] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0028] Reference Figures 1-7An integrated detection structure for railway TFDS and TWDS systems includes side boxes 1 installed on both sides of the railway. A CCD camera 101 for detection is installed inside the side box 1. The structure also includes a rotating shaft 2 rotatably installed inside the side box 1. A locking block 201 is provided on one end of the rotating shaft 2 located on the outer wall of the side box 1. The locking block 201 has multiple locking grooves 202. An end cover 203 is slidably installed on the outer wall of the side box 1. The end cover 203 has a limiting block 204 that cooperates with the locking grooves 202. A mounting leg 207 is fixedly connected to the rotating shaft 2. The bottom of the mounting leg 207 extends outward from the side box 1. The bottom of the side box 1 has a long groove 102 for the mounting leg 207 to move.
[0029] In this invention, before use, the mounting legs 207 are installed on the concrete roadbed located on both sides of the track and then fastened together with bolts. Then, the tilt angle of the side box 1 is adjusted. Specifically, the end cover 203 is pulled out of the side box 1, causing the limiting block 204 inside the end cover 203 to separate from the locking groove 202. At this point, the side box 1 can begin to rotate around the rotating shaft 2. After rotating to a suitable position, the end cover 203 is inserted again, causing the limiting block 204 on the end cover 203 to re-insert into the locking groove 202 on the locking block 201, thereby fixing the angle between the side box 1 and the rotating shaft 2. Furthermore, since the position of the mounting leg 207 is fixed during installation, and the top of the mounting leg 207 is fixedly connected to the rotating shaft 2, the position of the rotating shaft 2 can be fixed. At this time, rotating the side box 1 allows for easier angle adjustment, enabling the CCD camera 101 to better record the state of the wheel and achieve better detection results. Moreover, after long-term use, if the track experiences local settlement, the staff can readjust the angle of the side box 1 to adjust the position of the CCD camera 101, ensuring that the angle of the CCD camera 101 corresponds to the relative height of the wheel, avoiding distortion during measurement and improving measurement accuracy.
[0030] It should be noted that after the side box 1 is adjusted, the long groove 102 at the bottom of the side box 1 facilitates the placement of the mounting leg 207. Secondly, the mounting leg 207 can also be set in the form of a telescopic rod, thereby adjusting the height of the mounting leg 207 to adapt to different occasions. In this application, the structure of the side box 1 and CCD camera 101 is mainly used for wheel detection in the TWDS system. The side box 1 is also equipped with a connecting wire for connecting to the TFDS system to detect the bottom of the vehicle, thereby integrating the FDS and TWDS systems.
[0031] Reference Figure 4 and Figure 5A baffle 103 is fixedly connected to the inner wall of the side box 1. A rotating shaft 2 is located below the baffle 103. A support block 104 is fixedly connected to the baffle 103. The support block 104 is rotatably connected to the rotating shaft 2.
[0032] In this utility model, the baffle 103 can protect the components below the side box 1 and improve their service life. The support block 104 can improve the rotation and support effect between the side box 1 and the rotating shaft 2, and make it easier to adjust and use.
[0033] Reference Figures 5-7 The inner wall of the side box 1 is provided with multiple sleeves 206, and multiple insertion rods 205 are fixedly connected to the outer wall of the end cover 203. The multiple insertion rods 205 are slidably connected in the multiple sleeves 206 inside the side box 1.
[0034] When the end cover 203 is pulled, the insertion rod 205 located on the end cover 203 will move out of the sleeve 206. At this time, the side box 1 can be rotated. After the insertion rod 205 is inserted into the sleeve 206 again, it can be fixed again. The sleeve 206 is designed to make the insertion of the insertion rod 205 more convenient and to improve the fixing effect of the insertion rod 205.
[0035] Reference Figure 1 and Figure 2 The side box 1 is provided with an arc-shaped cover 303 for protecting the CCD camera 101. The two side walls of the side box 1 are provided with a fixing bracket 3. The fixing bracket 3 is fixedly installed with an air collecting cover 301. The arc-shaped cover 303 is provided with a spray outlet 304. A conveying pipe 302 is provided between the air collecting cover 301 and the spray outlet 304. The spray outlet 304 faces the CCD camera 101.
[0036] In this embodiment, when natural wind is generated, or when the natural wind is strong, the wind blowing into the wind collector hood 301 will be collected by the wind collector hood 301 and then converge into the delivery pipe 302. Due to the smaller cross-section, the air velocity in the delivery pipe 302 will be increased, and then it will be ejected from the nozzle 304 to blow away the dust on the surface of the CCD camera 101, thereby improving the detection effect. It should be noted that after the natural wind is gathered by the funnel-shaped wind collector hood 301, the air velocity in the narrower delivery pipe 302 will be increased due to the reduced pipe diameter. Finally, when it is ejected from the end of the pipe, it forms a directional high-speed airflow, which can blow away the dust and debris on the surface of the CCD camera 101 to achieve the dust removal effect.
[0037] Reference Figures 1-4 The top of the side box 1 is provided with a cover plate 4, which is inclined and there is a gap between the cover plate 4 and the top of the side box 1. A support plate 401 is provided on the outer wall of the cover plate 4, and the support plate 401 is connected to the outer wall of the side box 1.
[0038] The inclined cover plate 4 on the top is designed to allow rainwater and snow to slide quickly down the slope, preventing them from accumulating on the top and causing damage to the box structure or short circuits in the internal equipment due to water freezing. Secondly, the inclined angle can, to some extent, avoid direct sunlight at noon, reducing the impact of sunlight on the imaging effect of the detection equipment inside the side box 1, ensuring the clarity and accuracy of wheel detection. The gap between the top cover plate 4 and the side box 1 provides a channel for air circulation, effectively dissipating the heat generated by the equipment operation, maintaining a suitable internal working temperature, and improving the stability and service life of the equipment. Furthermore, given the large temperature difference in the railway trackside environment, the gap can balance the air pressure inside the side box 1 and the outside, preventing deformation or damage to the side box 1 due to air pressure differences. It can also avoid condensation problems caused by a sudden increase in the temperature of the side box 1.
[0039] Reference Figure 4 The inner wall of the side box 1 is provided with an inclined V-shaped plate 5, which is located in the middle of the side box 1. The two side walls of the side box 1 are provided with inclined guide plates 501. The outer wall of the side box 1 is provided with a first drain pipe 105 corresponding to the V-shaped plate 5 and a second drain pipe 106 corresponding to the guide plate 501.
[0040] In this invention, if some rainwater enters through the gap between the cover plate 4 and the top of the side box 1, the rainwater in the middle will fall onto the V-shaped plate 5 and then be discharged to the outside of the side box 1 through the first drain pipe 105. The rainwater on both sides will pass through the gap between the V-shaped plate 5 and the inner wall of the side box 1 and fall onto the guide plate 501. The inclined guide plate 501 will guide the rainwater and discharge it to the outside of the side box 1 through the second drain pipe 106, which can effectively prevent water from accumulating inside the side box 1.
[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
