Technical Field

[0001] The utility model belongs to the technical field of low-altitude alarm for rail transit, and particularly relates to a low-altitude alarm switching device for rail transit. Background Technique

[0002] The low-altitude alarm switching device for rail transit is an advanced technical device applied in the field of rail transit, aiming to ensure the safe operation of trains and improve the response speed and accuracy of the alarm system.

[0003] The existing low-altitude alarm devices are usually fixed in position, resulting in a limited alarm range. In the rail transit road, there are various potential threats. Since the low-altitude alarm device is fixed in position and does not have an adjustment function, threats existing at different heights cannot be detected and alarmed in time, which may seriously cause potential safety hazards to rail transit vehicles and result in a large amount of economic losses. Therefore, we propose a low-altitude alarm switching device for rail transit. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a low-altitude alarm switching device for rail transit. By setting a lifting component, specifically, starting the motor to drive the first gear to rotate, the first gear drives the rotating rod to rotate through the second gear, and the winding disc rotates accordingly. Then the winding disc realizes the winding or unwinding of the steel wire rope, so as to adjust the height of the low-altitude alarm switching device, expand the alarm range, improve safety, avoid dead corners and prevent potential threats from not being detected in time, and ensure the normal operation of rail vehicles. It solves the problem that the existing low-altitude alarm devices are usually fixed in position, resulting in threats existing at different heights not being detected and alarmed in time, which may seriously cause potential safety hazards to rail transit vehicles.

[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0006] The utility model is a low-altitude alarm switching device for rail transit, including a column. A low-altitude alarm switching device is arranged in front of the column. A lifting component is arranged at the top of the column. The lifting component includes a shielding shell. The bottom of the shielding shell is fixedly connected to the top of the column. A motor is fixedly connected to the top of the column. The left output end of the motor is fixedly connected to a first gear. The bottom of the first gear is meshed with a second gear. The center of the second gear is fixedly connected to a rotating rod. The left and right sides of the rotating rod penetrate through the column and extend to the outside. The rotating rod is rotatably connected to the column. Winding discs are fixedly connected to the left and right sides of the rotating rod. Steel wire ropes are wound inside the winding discs.

[0007] Further, a stabilizing component is arranged outside the column. The stabilizing component includes a lifting ring. Three fixing blocks are fixedly connected inside the lifting ring. The three fixing blocks are arranged in a circumferential array centered on the column. A connecting block is arranged on one side of the fixing block close to the column. A roller is rotatably connected inside the connecting block. A moving rod is fixedly connected to the center of one side of the connecting block close to the fixing block. A spring is sleeved outside the moving rod. A partition board is fixedly connected to the inner wall of the fixing block.

[0008] Further, a limiting plate is arranged above the moving rod. One side of the limiting plate away from the partition board is fixedly connected to the surface of the connecting block. One side of the moving rod away from the connecting block penetrates through the partition board and extends to the outside.

[0009] Further, the moving rod is slidably connected to the partition board. One end of the spring is fixedly connected to the surface of the connecting block. The other end of the spring is fixedly connected to the surface of the partition board.

[0010] Further, the outer surface of the roller is in contact with the outer surface of the column. An installation plate is fixedly connected to the front of the lifting ring. Two positioning plates are fixedly connected to the back of the low-altitude alarm switching device. A limiting block is fixedly connected to the top of the front of the column. A sliding rod is slidably connected inside the limiting block. The bottom of the sliding rod is fixedly connected to the top of the lifting ring.

[0011] Further, the winding disc is inside the retaining shell. The top of the retaining shell is arc-shaped. The positioning plate is inserted into the installation plate. The back of the low-altitude alarm switching device is in contact with the front of the installation plate.

[0012] The utility model has the following beneficial effects:

[0013] By setting the lifting component in the utility model, specifically, starting the motor drives the first gear to rotate. Then the first gear drives the rotating rod to rotate through the second gear, and the winding disc rotates accordingly. Then the winding disc realizes the winding or unwinding of the steel wire rope, and thus the height of the low-altitude alarm switching device can be adjusted, which can expand the alarm range, improve safety, avoid dead corners that may cause potential threats not to be detected in time, and ensure the normal operation of the rail vehicle.

[0014] By setting the stabilizing component in the utility model, specifically, under the elastic action of the spring, the connecting block makes the roller closely adhere to the surface of the column. Through the close adhesion of the roller to the column, it can make the stabilizing component drive the low-altitude alarm switching device to move more stably. At the same time, the roller rolls on the column, reducing the friction force and making the lifting smoother, ensuring the stability during lifting.

Obviously, the described embodiments are only some embodiments of the present utility model, rather than 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 efforts belong to the scope of protection of the present utility model.

[0025] Please refer to Figures 1-5As shown in the figure, the utility model relates to a low-altitude alarm switching device for rail transit, which includes a column 1. In front of the column 1, there is a low-altitude alarm switching device 11. At the top of the column 1, there is a lifting component 12. The lifting component 12 includes a shielding shell 121. The bottom of the shielding shell 121 is fixedly connected to the top of the column 1. A motor 122 is fixedly connected to the top of the column 1. The left output end of the motor 122 is fixedly connected to a first gear 123. The bottom of the first gear 123 is meshed with a second gear 124. A rotating rod 125 is fixedly connected to the center of the second gear 124. The left and right sides of the rotating rod 125 penetrate through the column 1 and extend to the outside. The rotating rod 125 is rotationally connected to the column 1. Reel discs 126 are fixedly connected to the left and right sides of the rotating rod 125. Steel wire ropes 127 are wound inside the reel discs 126. By setting the lifting component 12, specifically, starting the motor 122 drives the first gear 123 to rotate. Then, the first gear 123 drives the rotating rod 125 to rotate through the second gear 124, and the reel discs 126 rotate accordingly. Then, the reel discs 126 can wind or unwind the steel wire ropes 127, thereby adjusting the height of the low-altitude alarm switching device 11, expanding the alarm range, improving safety, avoiding dead corners that may cause potential threats not to be detected in time, and ensuring the normal operation of rail vehicles.

[0026] A stabilizing component 13 is arranged outside the column 1. The stabilizing component 13 includes a lifting ring 131. Three fixing blocks 132 are fixedly connected inside the lifting ring 131. The three fixing blocks 132 are arranged in a circumferential array centered on the column 1. A connecting block 134 is arranged on the side of the fixing block 132 close to the column 1. A roller 341 is rotationally connected inside the connecting block 134. A moving rod 343 is fixedly connected to the center of the side of the connecting block 134 close to the fixing block 132. A spring 344 is sleeved outside the moving rod 343. A partition plate 135 is fixedly connected to the inner wall of the fixing block 132. By setting the stabilizing component 13, specifically, under the elastic action of the spring 344, the connecting block 134 makes the roller 341 closely adhere to the surface of the column 1. Through the close adhesion of the roller 341 to the column 1, the stabilizing component 13 can drive the low-altitude alarm switching device 11 to move more stably. At the same time, the roller 341 rolls on the column 1, reducing the friction force and making the lifting smoother, ensuring the stability during lifting.

[0027] A limiting plate 342 is arranged above the moving rod 343. The side of the limiting plate 342 away from the partition plate 135 is fixedly connected to the surface of the connecting block 134. The side of the moving rod 343 away from the connecting block 134 penetrates through the partition plate 135 and extends to the outside. The limiting plate 342 is used to limit the connecting block 134 to prevent the connecting block 134 from shifting.

[0028] The moving rod 343 is slidably connected to the partition plate 135. One end of the spring 344 is fixedly connected to the surface of the connecting block 134, and the other end of the spring 344 is fixedly connected to the surface of the partition plate 135. The moving rod 343 is used to drive the connecting block 134 to move, so that the connecting block 134 has a certain moving space, thereby avoiding the situation that the roller 341 is stuck by an obstacle.

[0029] The outer surface of the roller 341 is in contact with the outer surface of the column 1. A mounting plate 133 is fixedly connected to the front surface of the lifting ring 131. Two positioning plates 111 are fixedly connected to the back surface of the low-altitude alarm switching device 11. A limiting block 14 is fixedly connected to the top of the front surface of the column 1. A sliding rod 141 is slidably connected inside the limiting block 14. The bottom of the sliding rod 141 is fixedly connected to the top of the lifting ring 131. The bottom of the steel wire rope 127 is fixedly connected to the top of the lifting ring 131. When the lifting ring 131 is lifted or lowered, it will drive the sliding rod 141 to slide on the limiting block 14, which is used to play a limiting role, so that the low-altitude alarm switching device 11 moves in a straight line, avoiding the situation of shaking or deviation.

[0030] The winding disc 126 is located inside the retaining shell 121. The top of the retaining shell 121 is arc-shaped. The positioning plate 111 is inserted into the mounting plate 133. The back surface of the low-altitude alarm switching device 11 is in contact with the front surface of the mounting plate 133. The low-altitude alarm switching device 11 is inserted into the mounting plate 133 through the positioning plate 111, and then the low-altitude alarm switching device 11 is installed and fixed with nuts.

[0031] A specific application of this embodiment is:

[0032] Insert the low-altitude alarm switching device 11 into the mounting plate 133 through the positioning plate 111, and then use nuts to install and fix the low-altitude alarm switching device 11. The low-altitude alarm switching device 11 mainly consists of a sensor, a data processing unit, an alarm generator, a communication interface, etc. The sensor is responsible for detecting flying objects or potential obstacles in the low-altitude area along the rail transit, such as drones, birds, etc. The data processing unit analyzes and processes the information collected by the sensor in real time. Once a potential threat is detected, the alarm generator will be immediately activated, and an alarm will be sent to the train driver and the dispatching center by means of sound, light or vibration. At the same time, the communication interface can transmit the alarm information to the train control system in real time to implement emergency measures such as automatic braking or deceleration. Start the motor 122 to drive the first gear 123 to rotate, then the first gear 123 drives the rotating rod 125 to rotate through the second gear 124, and the winding disc 126 will rotate accordingly. Then the winding disc 126 realizes the winding or unwinding of the steel wire rope 127. When the steel wire rope 127 is wound, it will drive the lifting ring 131 to move upward, and then the low-altitude alarm switching device 11 moves upward. When the steel wire rope 127 is unwound, the lifting ring 131 moves downward due to its own gravity, and then the low-altitude alarm switching device 11 moves downward. In this way, the height of the low-altitude alarm switching device 11 can be adjusted, which can expand the alarm range, improve safety, avoid dead angles that may cause potential threats not to be detected in time, and ensure the normal operation of the rail vehicle. At the same time, when the lifting ring 131 is lifted or lowered, it will drive the sliding rod 141 to slide on the limiting block 14, which is used for limiting, so that the low-altitude alarm switching device 11 moves in a straight line, avoiding shaking or deviation. At the same time, under the elastic action of the spring 344, the connecting block 134 will make the roller 341 close to the surface of the column 1, and the limiting plate 342 plays a limiting role on the connecting block 134 to avoid the deviation of the connecting block 134. By the close contact between the roller 341 and the column 1, it can make the stable component 13 drive the low-altitude alarm switching device 11 to move more stably. At the same time, the roller 341 rolls on the column 1, reducing the friction force and making the lifting smoother, avoiding jamming, and ensuring the stability during lifting.
