Description

Technical Field

[0001] This utility model relates to the field of rail brake components, specifically a rail brake linkage assembly. Background Technology

[0002] Industrial tracks refer to track systems used in the industrial field for transporting various materials and equipment or guiding the movement of mechanical parts. They are widely used in factories, mines and other places to transport raw materials, semi-finished products and finished products, such as tracks used to transport ore in mines and track systems used to load and unload goods in factories.

[0003] Currently, the braking method for industrial rail vehicles typically uses the braking of the drive motor to complete the braking process. However, when industrial rail vehicles are heavy, relying solely on the drive motor for braking will cause a large impact on the drive motor, which can easily lead to significant damage to the drive motor. Furthermore, the braking time of the drive motor is relatively long, resulting in slow braking response speed and other problems, making it difficult to meet the braking performance requirements of industrial rail vehicles. Therefore, those skilled in the art have provided rail brake linkage assemblies to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to provide a track brake linkage assembly to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A rail brake linkage assembly includes a movable plate, a support frame fixedly connected to the bottom surface of the movable plate, two industrial rails below the movable plate, and rail wheels rollingly connected to the outer surfaces of the two industrial rails. A drive shaft is fixedly mounted on the adjacent ends of the two rail wheels, and two brake wheels are fixedly mounted on the outer surface of the drive shaft. Two support cylinders are fixedly embedded in one side of the support frame, and cylinders are fixedly mounted on the inner walls of the two support cylinders.

The outer surfaces of the two brake pads are in contact with the outer surfaces of the two brake wheels, respectively.

[0007] As a further improvement of this utility model: the inner walls of the two support frames are inlaid with two bearing rings, and the inner rings of the two bearing rings are connected to the outer surface of the drive shaft.

[0009] As a further improvement of this utility model: a fixing block is fixedly installed on one side of the support frame, and the sides of the two support cylinders that are close to each other are connected to the outer surface of the fixing block.

[0010] As a further improvement of this utility model: two fixing members are fixedly connected to the outer surfaces of the two industrial tracks, and fixing holes are opened on the upper surfaces of the two fixing members.

[0011] As a further improvement of this utility model: the upper surface of the movable plate is provided with two sets of threaded fixing grooves, and the movable plate is located above the drive shaft.

[0021] Please see Figures 1-4In this embodiment of the utility model, the rail brake linkage assembly includes a movable plate 1. A support frame 2 is fixedly connected to the bottom surface of the movable plate 1. Two industrial rails 4 are provided below the movable plate 1. Rail wheels 3 are rolledly connected to the outer surfaces of the two industrial rails 4. A drive shaft 21 is fixedly installed at the end of the two rail wheels 3 that are close to each other. Two brake wheels 11 are fixedly installed on the outer surface of the drive shaft 21. Two support cylinders 5 are fixedly embedded in one side of the support frame 2. Cylinders 6 are fixedly installed on the inner walls of the two support cylinders 5. The cylinders 6 need to be connected to the pneumatic components and the brake control system. A linkage plate 7 is fixedly installed at the telescopic ends of the two cylinders 6. Two connecting rods 8 are fixedly installed on one side of the linkage plate 7. The outer surface of the support frame 2... Two circular openings 9 are provided, and brake pads 10 are fixedly installed at one end of each of the two connecting rods 8. The outer surfaces of the two brake pads 10 are in contact with the outer surfaces of the two brake wheels 11 respectively. The movable plate 1 can serve as the installation base and support platform for the entire component. The two sets of threaded fixing grooves 16 can be used to connect other equipment or components to realize the fixed installation of the component with the external system. The support frame 2 plays a supporting and connecting role and can provide installation positions for components such as track wheels 3 and support cylinders 5, ensuring the stability of the overall structure of the component. The linkage plate 7 moves under the drive of the cylinder 6, which can enable the connecting rod 8 to transmit the power of the cylinder 6 to the brake pads 10, so that the brake pads 10 can accurately contact the brake wheels 11 and apply braking force.

[0022] Two bearing rings 12 are embedded in the inner walls of the two support frames 2. The inner rings of the two bearing rings 12 are connected to the outer surface of the drive shaft 21. A sliding column 18 is fixedly connected to the outer surface of the linkage plate 7. A sliding hole 17 is opened on the outer surface of the linkage plate 7. The outer surface of the sliding column 18 is slidably connected to the inner wall of the sliding hole 17. A limit plate 19 is fixedly installed at one end of the sliding column 18. Two buffer pads 20 are fixedly installed on one side of the linkage plate 7. Both buffer pads 20 are located on one side of the limit plate 19. By setting the bearing rings 12, the friction and wear of the drive shaft 21 during rotation can be reduced, ensuring the stability and reliability of the drive shaft 21 during rotation and braking. Through the cooperation of the sliding column 18 and the sliding hole 17, the movement of the linkage plate 7 can be guided and limited, ensuring that the linkage plate 7 moves smoothly. This will allow the brake pad 10 to accurately contact the brake wheel 11. Through the cooperation of the buffer pads 20 and the limit plate 19, the linkage plate 7 can be limited and buffered when it resets and moves.

[0023] A fixing block 13 is fixedly installed on one side of the support frame 2. The sides of the two support cylinders 5 that are close to each other are connected to the outer surface of the fixing block 13. Two fixing parts 14 are fixedly connected to the outer surface of the two industrial rails 4. Fixing holes 15 are opened on the upper surface of the two fixing parts 14. Two sets of threaded fixing grooves 16 are opened on the upper surface of the moving plate 1. The moving plate 1 is located above the drive shaft 21. The fixing block 13 enhances the stability of the installation of the two support cylinders 5 and ensures the reliability of the cylinder 6 when it is working. The fixing parts 14 and fixing holes 15 can fix the industrial rails 4 in the required position and ensure the stability of the industrial rails 4.

[0024] The working principle of this utility model is as follows: When braking is required, the control system sends a command to the cylinder 6, and the cylinder 6 starts to work, which can push the linkage plate 7 to move. During the movement, the linkage plate 7 can drive the brake pads 10 to approach the brake wheel 11 through the connecting rod 8. As the cylinder 6 extends further, the outer surfaces of the two brake pads 10 are in close contact with the outer surfaces of the two brake wheels 11 respectively. The friction force causes the brake wheel 11 to decelerate. Since the brake wheel 11 is mounted on the surface of the drive shaft 21, the deceleration of the brake wheel 11 drives the track wheel 3 to decelerate. When braking is completed or braking needs to be released, the control system controls the cylinder 6 to retract, which drives the linkage plate 7, connecting rod 8 and brake pads 10 to reset. The brake pads 10 separate from the brake wheel 11, and the track brake linkage assembly returns to normal operation.
