Description
Technical Field
[0001] This utility model relates to the field of rail transit technology, specifically a rail transit anti-collision device. Background Technology
[0002] Urban rail transit systems refer to transportation systems that use vehicles running on fixed tracks in cities and are mainly used for urban passenger transport. Rail transit has long existed as a form of public transportation in cities and plays an increasingly important role.
[0003] A collision avoidance device for rail transit, disclosed in publication number CN 212172196 U, includes a platform and a pressure sensor. A vertical rod is fixed to the top outer wall of the platform with screws, and a first sliding groove is formed on the opposite side outer wall of the vertical rod. An upper crossbar and a lower crossbar are fixed to the opposite side of the vertical rod with screws, and rubber sleeves are provided on the circumferential outer walls of the upper and lower crossbars. A vibration sensor is installed inside the rubber sleeve on the circumferential outer wall of the lower crossbar, and the vibration sensor is connected to an electrical system via a wire. This invention, by positioning the upper crossbar 4 and lower crossbar 7 at a distance from the track, prevents passengers from falling onto the track and causing injury or death, thus protecting passenger safety. When a passenger collides with the railing, the vibration sensor vibrates, transmitting a signal to the electrical system. The electrical system then sends the signal to a speaker on the ceiling, which issues a warning.
[0004] However, the above-mentioned device still has some shortcomings in use. It relies solely on the outer rubber sleeve of the crossbar for cushioning, which has weak energy absorption capacity and is difficult to cope with strong collisions, which can easily lead to personnel injury or structural damage. At the same time, the crossbar is fixedly installed, which hinders people from getting on and off the train after it enters the station. Manual adjustment is inefficient and can easily leave blind spots in protection. Furthermore, the device is designed as an integrated unit and cannot be modularly installed according to the needs of different platforms and track sections, resulting in high costs and long cycles. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a rail transit anti-collision device that solves the problems of relying solely on the outer rubber sleeve of the crossbar for buffering, which has weak energy absorption capacity, is difficult to cope with strong collisions, and is prone to causing personnel injury or structural damage. At the same time, the crossbar is fixedly installed, which obstructs people from getting on and off the train after it enters the station. Manual adjustment is inefficient and easily leaves blind spots. Furthermore, the device is designed as an integrated unit, which cannot be modularly installed according to the needs of different platforms and track sections, resulting in high costs and long cycles.
[0006] This utility model provides the following technical solution: a rail transit anti-collision device, including a protective component, the protective component including two mounting columns, two connecting rods fixedly connected between the two mounting columns, mounting boxes fixedly connected to the opposite sides of the two mounting columns, movable grooves opened on the surface of the two mounting columns, empty grooves opened on the surface of the two mounting boxes, and baffles provided inside the two empty grooves, the two baffles being movable inside the corresponding movable grooves respectively;
[0007] Two contact plates are fixedly connected between the two mounting columns. A row of through holes is opened on the surface of each of the two connecting rods. A short rod is slidably installed inside each of the through holes. A protective plate is fixedly connected to one end of each row of short rods. A long plate is fixedly connected to the other end of each row of short rods. A limit switch is fixedly installed on the surface of each of the two long plates. A spring is sleeved on the surface of each short rod.
[0008] Preferred technical solution 1: A row of vertical plates is fixedly connected between the two protective plates, and the surfaces of the two protective plates and each of the vertical plates are covered with protective pads.
[0009] Preferred technical solution 2: Screws are rotatably installed on the inner sidewalls of both empty slots, threaded grooves are opened on the surface of both stop gates, and the two stop gates are threaded onto the outside of the two screws through the two threaded grooves respectively. Drive motors are fixedly connected to the surface of both mounting boxes, and the output ends of the two drive motors extend into the interior of the connected mounting boxes and are fixedly connected to the two screws respectively.
[0010] Preferred technical solution 3: Limiting rods are fixedly connected to the inner sidewalls of the two empty slots, and limiting grooves are opened on the surfaces of the two blocking gates. The two blocking gates are slidably sleeved on the two limiting rods through the limiting grooves.
[0011] Preferred technical solution four: The bottom ends of the two mounting columns are fixedly connected to mounting plates, and the surfaces of the two mounting plates are provided with multiple mounting holes.
[0012] Preferred technical solution five: An alarm light is fixedly installed at the top of each of the two mounting columns, and the limit switch is electrically connected to the alarm light.
[0013] Compared with the prior art, this utility model provides a rail transit anti-collision device with the following beneficial effects: In use, multiple protective components are combined by installing them in a suitable position through a mounting plate to form a protective device. When a person collides with the device, they first come into contact with the protective plate. Subsequently, the protective plate is pushed by force to slide the short rod in the through hole on the surface of the connecting rod. The spring sleeved on the surface of the short rod is compressed and further absorbs the collision energy. At the same time, the long plate at the other end of the short rod moves synchronously with the short rod. When the long plate contacts the contact plate fixedly connected between the mounting column and the mounting post, the limit switch fixedly installed on the surface of the long plate is triggered. Since the limit switch is connected to the alarm light fixedly installed at the top of the mounting post, the alarm light immediately lights up to issue a collision warning signal.
[0014] Before the train enters the station, two barriers extend to form a barrier, preventing passengers from falling onto the tracks and causing injury or death, thus protecting passenger safety. After the train enters the station, the drive motor rotates, which in turn rotates the screw, causing the barriers to retract into the mounting box, allowing people to enter and exit quickly and easily.

Two connecting rods 3 are fixedly connected between the two mounting posts 2. Mounting boxes 4 are fixedly connected to the opposite sides of the two mounting posts 2. Movable grooves are opened on the surface of the two mounting posts 2. Hollow grooves 5 are opened on the surface of the two mounting boxes 4. A stop door 6 is provided inside the two hollow grooves 5. The two stop doors 6 can move inside the corresponding movable grooves respectively.
[0021] Two contact plates 7 are fixedly connected between the two mounting posts 2. A row of through holes 8 is opened on the surface of the two connecting rods 3. A short rod 9 is slidably installed inside each through hole 8. A protective plate 10 is fixedly connected to one end of each row of short rods 9. A long plate 11 is fixedly connected to the other end of each row of short rods 9. A limit switch 12 is fixedly installed on the surface of each of the two long plates 11. A spring 13 is sleeved on the surface of each short rod 9.
[0022] Example 2: The difference between this example and Example 1 is that a row of vertical plates 14 are fixedly connected between the two protective plates 10, and the surfaces of the two protective plates 10 and each vertical plate 14 are covered with protective pads.
[0023] Example 3: The difference between this example and Example 1 is that, in this example, screws 15 are rotatably installed on the inner sidewalls of the two empty slots 5, threaded grooves 16 are opened on the surface of the two stop gates 6, and the two stop gates 6 are threadedly installed on the outside of the two screws 15 through the two threaded grooves 16 respectively. Drive motors 19 are fixedly connected to the surface of the two mounting boxes 4, and the output ends of the two drive motors 19 extend into the interior of the connected mounting boxes 4 and are fixedly connected to the two screws 15 respectively.
[0024] Example 4: The difference between this example and Example 1 is that the inner sidewalls of the two empty slots 5 are fixedly connected with limit rods 17, and the surfaces of the two gates 6 are provided with limit grooves 18. The two gates 6 are slidably sleeved on the two limit rods 17 through the limit grooves 18.
[0025] Example 5: The difference between this example and Example 1 is that the bottom ends of the two mounting posts 2 are fixedly connected to mounting plates 20, and the surfaces of the two mounting plates 20 are provided with multiple mounting holes.
[0026] Example 6: The difference between this example and Example 1 is that an alarm light 21 is fixedly installed on the top of each of the two mounting posts 2, and the limit switch 12 is electrically connected to the alarm light 21.
[0027] In summary, the control method and detailed connection means of this rail transit anti-collision device are known technologies in the field. Those skilled in the art can connect all electrical components and their compatible power supplies through wires, and should select a suitable controller according to the actual situation to meet the control requirements. The detailed connection means and control scheme are known technologies in the field. The following mainly introduces the working principle and process, and will not explain the electrical control. At the same time, the screw 15 and the thread groove 16 meet the self-locking condition and the thread helix angle is less than the equivalent friction angle.
[0028] In use, multiple protective components 1 are assembled in appropriate positions via mounting plate 20 to form a protective device. When a person collides with the device, they first come into contact with the protective plate 10. Subsequently, the protective plate 10 is pushed by force to slide the short rod 9 in the through hole 8 on the surface of the connecting rod 3. The spring 13 sleeved on the surface of the short rod 9 is compressed and further absorbs the collision energy. At the same time, the long plate 11 at the other end of the short rod 9 moves synchronously with the short rod 9. When the long plate 11 contacts the contact plate 7 fixedly connected between the mounting column 2, the limit switch 12 fixedly installed on the surface of the long plate 11 is triggered. Since the limit switch 12 is electrically connected to the alarm light 21 fixedly installed at the top of the mounting column 2, the alarm light 21 immediately lights up to issue a collision warning signal.
[0029] Before the train enters the station, the two barrier doors 6 extend to form a barrier, preventing passengers from falling onto the tracks and causing injury or death, thus protecting passenger safety. After the train enters the station, the drive motor 19 rotates, which drives the screw 15 to rotate, thereby causing the barrier doors 6 to retract into the mounting box 4, allowing personnel to enter and exit quickly and easily.
