Description

Technical Field

[0001] This utility model relates to a train anti-runaway stop device, specifically to a train anti-runaway stop device positioning indicator. Background Technology

[0002] A train anti-runaway stop, also known as a train anti-runaway device, is a safety device used on railway lines. Installed between two rails, it primarily stops and prevents runaway trains by applying friction braking to the inner surfaces of the wheelsets. To improve the safety of anti-runaway devices, it is necessary to monitor their operational status; therefore, the ability to indicate the braking and release states of the anti-runaway device is crucial. Utility Model Content

[0003] The purpose of this utility model is to overcome the defects and shortcomings of the above-mentioned background technology and provide a train anti-runaway stop device that can indicate the braking and release status of the anti-runaway stop device.

[0004] To achieve the above objectives, this utility model provides a train anti-runaway stop device positioning indicator, including a protective cover and a mounting base, a brake travel switch, a release travel switch, a push rod, and a stop block disposed within the protective cover. The push rod is disposed on the mounting base and arranged along the length of the mounting base, with one end connected to an indicator rod and the other end connected to a connecting seat. The connecting seat is mounted on the drive screw of the stop device, and the two are threaded together, so that the rotation of the drive screw drives the connecting seat to move linearly, pushing the push rod to move linearly along the length of the mounting base. The indicator rod is provided with an indicator mark for indicating whether the stop device is in the braking or release position, and the end of the indicator rod away from the push rod extends out of the protective cover. The stop block is connected to the push rod. The brake travel switch and the release travel switch are mounted on the mounting base and correspond to the two ends of the stop block, so that the stop block moves linearly under the drive of the push rod, triggering the corresponding travel switch. Each anti-slip device has a position indicator on its braking mechanism. It has one braking and one release limit switch installed inside. When the device moves to the braking or release position, the corresponding switch closes, stopping the mechanism and indicating the device's stopping status. It has a simple structure and is easy to use.

[0005] Furthermore, a connecting plate is provided on the impact block, and the push rod passes through the connecting plate and is locked by locking nuts located on both sides of the connecting plate. The locking nuts are threadedly connected to the push rod. The design of the connection structure between the push rod and the impact block through the locking nuts in this technical solution facilitates the adjustment of the impact block's position, thereby meeting the requirements of the brake rail opening size. Adjustment only requires adjusting the position of the locking nuts, making adjustment convenient and allowing for the use of brake rail openings of different sizes, thus demonstrating strong versatility.

[0006] Furthermore, the indicator markings consist of two different color segments painted on the indicator bar to distinguish whether the anti-rollover device is in the braking or releasing position. The two different colors on the markings are more conspicuous, making it easier to observe and distinguish whether the parking device is in the braking or releasing position.

[0007] Furthermore, the indicator rod is provided with an internally threaded hole coaxial with it, and the indicator rod is threadedly connected to the push rod through the internally threaded hole. This design facilitates the assembly of the device.

[0008] Furthermore, the brake travel switch and the release travel switch are respectively mounted on the mounting base via mounting plates. The mounting plate has a circular mounting hole, and the mounting base has an oblong mounting hole. The mounting plate is connected to the mounting base via bolts inserted into the circular and oblong holes. The oblong holes are provided to adjust the position of the switches, thereby meeting the requirements for the formation of the travel switches and satisfying the requirements for the brake rail opening size.

[0009] Furthermore, the push rod is connected to the connecting seat via a fixing plate and connecting screws, with the fixing plate being fixedly connected to the push rod. This structure facilitates the installation of the push rod.

[0010] Furthermore, the impact block is slidably connected to the guide shaft mounted on the mounting base. This sliding engagement between the impact block and the guide shaft improves the smoothness of the impact block's movement, thereby ensuring the stability of the device's operation and the accuracy of its indications.

[0011] Compared with the prior art, the present invention has the following technical effects:

[0012] 1. The positioning indicator of this utility model is installed on the first-position braking mechanism of each anti-rollover stop device. During operation, the drive screw of the anti-rollover stop device drives the connecting seat to move linearly. Under the push of the connecting seat, the push rod pushes the impact block to move linearly, thereby driving the indicator rod to move linearly. When the impact block contacts the corresponding brake limit switch and release limit switch, the corresponding switch closes, stopping the mechanism and indicating the stopping status of the equipment. It can clearly indicate whether the braking is in place. It is easy to use, with a simple and compact overall structure, reasonable design, and strong practicality. Moreover, the positioning indicator is connected to the drive screw of the anti-rollover stop device. The status of the anti-rollover device is directly transmitted to the positioning indicator through the drive screw. The drive screw is directly connected to the connecting seat, and the linear movement of the threaded seat directly drives the movement of the impact block. The transmission error is small, the indicated status is accurate, and the safety of use is high.

[0013] 2. The design of the push rod and the impact block of this utility model is based on the connection structure of the locking nut, which makes it easy to adjust the position of the impact block to meet the requirements of the brake rail opening size. The adjustment only requires adjusting the position of the locking nut, which is convenient and can be used with brake rail openings of different sizes, making it highly versatile.

[0018] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered by the claims.

[0019] The following is a reference to the appendix. Figure 1 and 2 This invention details the preferred embodiment of the train anti-runaway stop device's positioning indicator. This positioning indicator is installed on the first-position braking mechanism of the anti-runaway stop device and internally houses a brake and a release limit switch 8. When the device moves to the braking or release position, the corresponding switch closes, sending a feedback signal to the control system to stop the mechanism and indicate the device's stopping status. The stop device of this invention is a type of internally supported intelligent anti-runaway stop device and intelligent parking system disclosed in Utility Model Patent CN 222713486 U, as well as other anti-runaway devices with screw-driven braking mechanisms.

[0020] Example: Figure 1 and 2As shown, the train anti-runaway stop device in this embodiment includes a protective cover 11 and a mounting base 1, a brake travel switch 5, a release travel switch 8, a push rod 6, and a stop block 9 disposed within the protective cover 11. The push rod 6 is disposed on the mounting base 1 and arranged along the length direction of the mounting base 1. One end of the push rod 6 is connected to an indicator rod 10, and the other end is connected to a connecting seat 7. The connecting seat 7 is mounted on the drive screw of the stop device and is threadedly connected to the drive screw, so that the rotation of the drive screw drives the connecting seat 7 to move linearly, thereby pushing the push rod 6 to move linearly along the length direction of the mounting base 1. The stop block 9 is connected to the push rod 6 and is slidably connected to a guide shaft 2 mounted on the mounting base 1. The slidable connection between the stop block 9 and the guide shaft 2 ensures smooth movement of the stop block, ensuring the stability and accuracy of the device.

[0021] An indicator mark is provided on the indicator rod 10 to indicate whether the parking device is in the braking or releasing position. The end of the indicator rod 10 away from the push rod 6 extends out of the protective cover 11. For easy observation, the indicator rod 10 is painted with two different color segments to distinguish whether the parking device is in the braking or releasing position. In this embodiment, red and green are used. The red segment is located at the end of the indicator rod 10 away from the push rod 6, and the green segment is located at the end closer to the push rod 6. At this time, when only red is visible outside the protective cover 11, it indicates that the device is in the braking position; when both red and green are visible outside the cover 11, it indicates that the device is in the releasing position. At this time, if... Figure 1 and 2 As shown, the relief limit switch 8 is located at the end closer to the indicator rod 10, and the braking limit switch 5 is located at the end farther from the indicator rod 10. In other embodiments of this utility model, the markings on the indicator rod 10 can also be made using other marking methods, such as color markings or text markings.

[0022] In this embodiment, the brake travel switch 5 and the release travel switch 8 are mounted on the mounting base 1, corresponding to both ends of the impact block 9, and are kept at a certain distance from both ends of the impact block 9, so that the impact block 9 moves linearly under the drive of the push rod 6 to trigger the corresponding travel switch. Both the brake travel switch 5 and the release travel switch 8 are connected to the control module of the parking device to feed back the switch signal to the control module. In this embodiment, both the brake travel switch 5 and the release travel switch 8 are roller-type travel switches. The brake travel switch 5 and the release travel switch 8 are mounted on both sides of the mounting base 1 via the mounting plate 4 and bolts, respectively. The rollers of the travel switches are located on both sides of the guide shaft 9, so that the impact block 9 contacts the rollers when it moves, thereby triggering the travel switch.

[0023] When applying the train anti-runaway stop device in this embodiment, the device is installed on the first-position braking mechanism of each anti-runaway stop device. During operation, the drive screw of the anti-runaway stop device drives the connecting seat 7 to move linearly. Under the push of the connecting seat 7, the push rod 6 pushes the impact block 9 to move linearly along the guide shaft 9, thereby driving the indicator rod 10 to move linearly. When the impact block 9 contacts the brake travel switch 5, the brake travel switch 5 closes, sending a feedback signal to the control module to stop the braking mechanism. At this time, only red is visible on the indicator rod 10 outside the protective cover 11, indicating that the stop device is in the braking state. When the drive screw reverses, causing the push rod 6 to push the impact block 9 to contact the release travel switch 8, the indicator rod 10 will show both red and green colors outside the protective cover 11, indicating that the stop device is in the release position.

[0024] During assembly, to facilitate adjustment of the position of the impact block 9 and meet the requirements of the brake rail opening size, the impact block 9 and the push rod 6 are connected in the following way: a connecting plate 12 is provided on the impact block 9, and the connecting plate 12 is fixedly connected to the impact block 9. A through hole is opened in the connecting plate 12, and the push rod 6 passes through the connecting plate 12 and is locked by locking nuts 3 located on both sides of the connecting plate 12. The locking nuts 3 are threadedly connected to the push rod 6. With this connection method, when adjusting the position of the impact block 9, only the position of the locking nuts 3 needs to be adjusted, which is convenient to use. By adjusting the position of the impact block 9, the stopping position of the impact block 9 can be adjusted to meet the requirements of the brake rail opening size.

[0025] In this embodiment, to facilitate the assembly of the positioning indicator device, an internal threaded hole coaxial with the indicator rod 10 is provided on the indicator rod 10, and the indicator rod 10 is threadedly connected to the push rod 6 through the internal threaded hole. The push rod 6 is connected to the connecting seat 7 through the fixing plate 13 and the connecting screw, and the fixing plate 13 is fixedly connected to the push rod 6.

[0026] In another embodiment of this utility model, to facilitate adjustment of the stopping position of the impact block 9, the brake travel switch 5 and the release travel switch 8 are respectively mounted on the mounting base 1 via a mounting plate 4. A circular mounting hole is provided on the mounting plate 4, and an oblong mounting hole is provided on the mounting base 1. The mounting plate is connected to the mounting base 1 via bolts located in the circular and oblong mounting holes. By adjusting the position of the bolts in the oblong mounting holes, the position of the mounting base is adjusted, thereby adjusting the stopping position of the impact block to meet the forming requirements and thus satisfying the requirements of different sized openings in the brake rail, improving the versatility of this utility model.

[0027] This invention utilizes a connecting seat mounted on a drive screw of the anti-slip device. The linear movement of the connecting seat drives the movement of a push rod, which in turn moves the impact block. The impact block contacts corresponding brake and release limit switches, causing these switches to close and stopping the anti-slip device's braking mechanism. This design indicates the device's stopping status. The structure is simple, rationally designed, and easy to manufacture and assemble. Furthermore, the positioning indicator is connected to the drive screw of the anti-slip device, directly transmitting the anti-slip device's status to the positioning indicator via the drive screw. The drive screw is directly connected to the connecting seat, and the linear movement of the threaded seat directly drives the impact block, resulting in small transmission errors, accurate status indication, and high safety in use.

[0028] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
