Description

Technical Field

[0001] This utility model belongs to the field of track emergency braking technology, and in particular relates to an emergency braking triggering device for a track signaling system. Background Technology

[0002] Emergency braking in track signaling systems is a core component of railway safety systems, designed to quickly stop trains automatically or semi-automatically to prevent accidents. Emergency braking is typically used in situations such as train speeding, erroneous signals, track obstructions, and equipment malfunctions. Its goal is to ensure trains can stop safely within a short time to mitigate the severity of an accident or avoid potential collisions.

[0003] In the prior art, the train braking system cannot be automatically triggered in case of an emergency during train operation, which may lead to accidents or incidents. Therefore, we propose an emergency braking triggering device for a track signal system. Utility Model Content

[0004] The purpose of this invention is to provide an emergency braking triggering device for a track signaling system. Through the cooperation of components such as the motor, push rod, and brake block of the emergency braking mechanism, when an emergency occurs during train operation, the signal receiving board detects the danger and starts the motor, driving the threaded rod to rotate. This rotation drives the threaded sleeve to move linearly through the limiting shaft, pushing the push rod to press the moving plate, causing the brake block to contact the wheel for emergency braking. This design achieves the effect of emergency braking of the train, preventing accidents or incidents and solving existing problems.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is an emergency braking triggering device for a track signal system, including a wheel control box, a wheel is installed inside the wheel control box, a signal receiving plate is installed on the top of the wheel control box, and an emergency braking mechanism is installed inside the wheel control box. The emergency braking mechanism includes a motor, which is fixedly connected inside the wheel control box. A threaded rod is fixedly connected to the output end of the motor. A threaded sleeve is threadedly connected to the circumferential surface of the threaded rod. A push rod is fixedly connected to the side of the threaded sleeve. A moving groove is opened inside the wheel control box. A moving plate is slidably connected inside the moving groove. A brake block is fixedly connected to the bottom of the moving plate.

[0006] Furthermore, a compression spring is fixedly connected to the inner wall of the wheel control box. The end of the compression spring away from the inner wall of the wheel control box is fixedly connected to the side of the moving plate. The initial state of the compression spring is a relaxed state, which is intended to ensure that the moving plate can automatically reset and reduce manual intervention.

[0007] Furthermore, a limiting plate is fixedly connected inside the wheel control box. The side of the limiting plate penetrates the circumferential surface of the threaded rod. A limiting shaft is fixedly connected to the side of the limiting plate. The circumferential surface of the limiting shaft penetrates and slides through the side of the threaded sleeve. The purpose of this is to limit the displacement distance of the threaded sleeve and prevent the threaded sleeve from rotating during movement.

[0008] Furthermore, there are two push rods, brake blocks, and compression springs, which are symmetrical to each other along the vertical central axis of the wheel control box. The side of the moving plate is located on the displacement trajectory of the push rod, the purpose of which is to ensure that the movement of the push rod can compress the moving plate.

[0009] Furthermore, the wheel control box is equipped with a warning mechanism, which includes a trigger rod fixedly connected to the side of the threaded sleeve. The inner wall of the wheel control box is equipped with a start button, and the top of the wheel control box is equipped with a warning reminder device, the purpose of which is to remind the driver and the people in the vehicle.

[0010] Furthermore, a reset spring is fixedly connected to the inner wall of the wheel control box. The end of the reset spring away from the inner wall of the wheel control box is fixedly connected to the circumferential surface of the start button. The purpose of this is to ensure that the start button can automatically reset and reduce manual intervention.

[0011] Furthermore, the trigger end of the start button is located on the displacement trajectory of the trigger rod, the purpose of which is to ensure that the movement of the trigger rod can press the start button.

[0012] This utility model has the following beneficial effects: This utility model utilizes the cooperation between components such as the motor, push rod, and brake block of the emergency braking mechanism. When an emergency occurs during train operation, the signal receiving board detects the danger and starts the motor, driving the threaded rod to rotate. This rotation, via the limiting shaft, causes the threaded sleeve to move linearly, pushing the push rod to press against the moving plate. This causes the brake block to contact the wheel for emergency braking. This design achieves the effect of emergency braking of the train, preventing accidents or incidents.

[0013] This invention utilizes the interplay between components such as the trigger rod, warning reminder, and return spring of the warning mechanism. The movement of the threaded sleeve triggers the emergency braking mechanism, which in turn moves the trigger rod and triggers the button, activating the warning reminder. This promptly issues a warning signal to remind the driver and occupants to take emergency measures. This design achieves the effect of timely warning in emergency situations, ensuring timely alerts and safety in emergency situations.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0020] As shown in the figure, a compression spring 48 is fixedly connected to the inner wall of the wheel control box 1. The end of the compression spring 48 away from the inner wall of the wheel control box 1 is fixedly connected to the side of the moving plate 46. The initial state of the compression spring 48 is a relaxed state, which is to ensure that the moving plate 46 can automatically reset and reduce manual intervention.

[0021] As shown in the figure, a limiting plate 49 is fixedly connected inside the wheel control box 1. The side of the limiting plate 49 penetrates the circumferential surface of the threaded rod 42. A limiting shaft 410 is fixedly connected to the side of the limiting plate 49. The circumferential surface of the limiting shaft 410 penetrates and slides through the side of the threaded sleeve 43. The purpose is to limit the displacement distance of the threaded sleeve 43 and prevent the threaded sleeve 43 from rotating during movement.

[0022] As shown in the figure, there are two push rods 44, brake blocks 47 and compression springs 48, which are symmetrical to each other along the vertical central axis of the wheel control box 1. The side of the moving plate 46 is located on the displacement trajectory of the push rod 44. The purpose is to ensure that the movement of the push rod 44 can compress the moving plate 46.

[0023] As shown in the figure, a warning mechanism 5 is provided inside the wheel control box 1. The warning mechanism 5 includes a trigger rod 51, which is fixedly connected to the side of the threaded sleeve 43.

[0025] As shown in the figure, the trigger end of the start button 52 is located on the displacement trajectory of the trigger rod 51. The purpose of this is to ensure that the movement of the trigger rod 51 can press the start button 52.

[0026] A specific application of this embodiment is as follows: When an emergency occurs during train operation, the signal receiving board 3 detects the danger and starts the motor 41. The output of the motor 41 automatically rotates, driving the threaded rod 42 to rotate. The rotation of the threaded rod 42 drives the threaded sleeve 43 to move linearly through the limiting shaft 410. The movement of the threaded sleeve 43 drives the push rod 44 to move. During the movement of the push rod 44, it presses against the moving plate 46. The moving plate 46 moves within the moving groove 45 under force. The movement of the moving plate 46 drives the brake block 47 to move. The brake block 47 moves and contacts the wheel 2, performing emergency braking. When the danger is cleared, the push rod 44... 4. The moving plate 46 moves away from the side, causing it to reset via the compression spring 48. When the threaded sleeve 43 moves to trigger the emergency braking mechanism 4, it simultaneously drives the trigger rod 51 to move. During the movement of the trigger rod 51, the trigger end contacts the start button 52. After the start button 52 is triggered, the warning reminder 53 is activated, issuing a warning signal to promptly remind the driver and occupants of the current emergency so that they can react quickly and take appropriate measures to ensure safety. When it moves away from the start button 52, the start button 52 automatically resets via the action of the reset spring 54, turning off the warning reminder 53, thereby stopping the issuance of the warning signal and restoring normal operation.
