Description

Technical Field

[0001] This utility model relates to the field of alarm devices, and in particular to a vehicle stop safety distance alarm device. Background Technology

[0002] In railway transportation systems, wheel stops are required at the end of dead-end tracks to prevent locomotives and rolling stock from accidentally crossing the line. Traditional protection methods rely on wheel stop indicators to visually indicate the location, but these are prone to damage and difficult to identify in low visibility conditions. To address this issue, existing technologies utilize proximity sensors, alarm hosts, and alarms installed inside the railway rails to proactively alert to approaching vehicles. Furthermore, solar power is used to reduce costs, effectively overcoming the passive warning shortcomings of traditional wheel stop indicators and improving the safety of shunting operations to a certain extent.

[0003] However, in existing technologies, core components such as proximity sensors and alarms are mostly fixed installations, which cannot be flexibly adjusted according to on-site operation requirements. For example, the passage of inspection vehicles and equipment maintenance may hinder temporary operations. In addition, the components of the device are mostly rigidly connected, and disassembly and replacement require the removal of a large number of fixed structures, which is complicated and affects the efficiency of fault handling, thus having certain defects.

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not 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 effort are within the protection scope of the present utility model.

[0036] This utility model provides, for example Figures 1-3 The vehicle stop safety distance alarm device shown.

[0037] Example 1: Includes a base 1, an alarm host 2, a rotating base 3, a drive column 4, a mounting assembly 5, a mounting column 6, a stop indicator 7, and an alarm 8. The base 1 is located on the side of the train track. The alarm host 2 is fixedly installed on the top of the base 1 and is connected to a proximity switch or camera installed on the train track. When a train passes the proximity switch, the proximity switch or camera sends an electrical signal to the alarm host 2. The alarm host 2 controls the stop indicator 7 and the alarm 8 to perform alarm operations via cables. The alarm host 2, stop indicator 7, and alarm 8 operate under external power supply, which is existing technology and will not be described in detail here. The rotating base 3 is fixedly installed on the top of the base 1, and the drive column 4... The transmission is mounted on the rotating base 3, which drives the drive column 4 to rotate via an electrical and gearbox structure. This is existing technology and will not be described in detail here. The mounting column 6 is set on one side of the drive column 4 via the mounting assembly 5. The vehicle stop indicator 7 and the alarm 8 are mounted on the outside of the mounting column 6. The vehicle stop indicator 7 and the alarm 8 are electrically connected to the alarm host 2. When a train approaches the vehicle stop indicator 7 and the alarm 8, or when an inspection vehicle needs to pass through the location of the vehicle stop indicator 7 and the alarm 8, the rotating base 3 can drive the mounting column 6 to rotate around the drive column 4 via the drive column 4 and the mounting assembly 5, so that the mounting column 6, the vehicle stop indicator 7 and the alarm 8 no longer block or restrict the passage of vehicles on the track.

[0038] Furthermore, the mounting assembly 5 includes a fence frame 51, a fixing collar 52, a mounting sleeve 53, a locking assembly 55, and a supporting collar 54. The fence frame 51 is disposed on one side of the drive column 4. One side of the fixing collar 52 is fixedly connected to the fence frame 51. The fixing collar 52 is fixedly installed on the outside of the mounting column 6 and is fixedly connected to the mounting column 6 by bolts. One side of the mounting sleeve 53 is fixedly connected to the fence frame 51. The mounting sleeve 53 is installed on the outside of the drive column 4 through the locking assembly 55. The supporting collar 54 is fixedly sleeved on the outside of the drive column 4. The top of the supporting collar 54 fits against the mounting sleeve 53. Under the action of the supporting collar 54, it is convenient for the mounting sleeve 53 at the end of the fence frame 51 to be sleeved at a specified height outside the drive column 4.

[0039] Furthermore, the mounting assembly 5 also includes a support frame 56 and a support roller 57. The support frame 56 is fixedly installed at the bottom of the fence frame 51, and the support roller 57 is installed at the bottom of the support frame 56. The bottom of the support roller 57 is in contact with the base 1. The support frame 56 and the support roller 57 can support the fence frame 51, thereby reducing the weight of the fence frame 51 acting on the drive column 4 and thus improving the service life of the drive column 4.

[0040] Example 2: Based on Example 1, the locking assembly 55 includes a fixed housing 551, a connecting block 553, and a locking rod 552. The fixed housing 551 is fixedly connected to the fence frame 51. The connecting block 553 is slidably disposed inside the fixed housing 551. One end of the locking rod 552 is fixedly connected to the connecting block 553. The outer wall of the locking rod 552 is slidably inserted into the mounting sleeve 53. The outer wall of the drive column 4 is provided with a locking groove. One end of the outer wall of the locking rod 552 is slidably engaged with the inner cavity of the locking groove. Under the action of the locking rod 552, the mounting sleeve 53 can be stably engaged with the outside of the drive column 4, and the drive column 4 can also drive the mounting sleeve 53 to rotate synchronously through the locking rod 552.

[0041] Furthermore, the locking assembly 55 also includes a handle 554, a guide rod 555, and a limiting spring 556. The end of the handle 554 is fixedly connected to the connecting block 553. The outer wall of the fixed housing 551 has a sliding hole that matches the handle 554, so that the handle 554 can drive the connecting block 553 to slide inside the fixed housing 551, thereby separating the locking rod 552 from the drive column 4, allowing the fence frame 51 to be disassembled and maintained directly. The guide rod 555 is fixedly connected to the inside of the fixed housing 551, and the outer wall of the guide rod 555 is slidably inserted into the connecting block 553. The limiting spring 556 is slidably sleeved on the outside of the guide rod 555. The limiting spring 556 is located on the side of the connecting block 553 away from the locking rod 552. The limiting spring 556 can provide an elastic compressive force to the locking rod 552 through the connecting block 553, thereby ensuring the stability of the locking rod 552 and the drive column 4.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
