Description

Technical Field

[0001] This utility model relates to the technical field of safety protection and early warning devices, and in particular to a railway construction safety protection and early warning device. Background Technology

[0002] With the large-scale development of railway construction and maintenance, safety issues at construction sites have received increasing attention. During railway construction, workers often need to perform high-risk operations near the tracks, thus requiring effective safety protection facilities to ensure the safety of the construction area and personnel.

[0003] For example, Chinese utility model patent application number 202420590488.7 discloses a railway construction safety protection and early warning device. The device includes a support frame, a monitoring box, and a vest. The top of the support frame is connected to the bottom of the monitoring box. The monitoring box contains a camera, a controller, and a speaker. The vest has a connecting fabric on its exterior, and a vibration motor and an alarm are mounted on the connecting fabric. This utility model provides a railway construction safety protection and early warning device with dual warning components. When the monitoring box detects a train approaching via the camera, it provides an initial warning to the driver through supplemental lighting of warning signs and a loudspeaker announcement. Simultaneously, the alarm and vibration motor on the vest provide an independent warning to workers. This two-way warning system further enhances the safety warning effect and reduces safety hazards caused by trains approaching.

[0004] While the aforementioned devices can be installed on tracks for easy movement, the different track widths, particularly narrow and standard gauge tracks, prevent the devices from being interchangeable. Furthermore, the complex environment at railway construction sites often involves significant mechanical vibrations, which can negatively impact protective and warning devices, leading to performance degradation or damage. Additionally, warning signs are often inflexible, bulky, and difficult to store, resulting in them occupying a large amount of storage space when not in use and being easily damaged during transportation. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a railway construction safety protection and early warning device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a railway construction safety protection and early warning device, comprising a fixed base, a support frame fixedly connected to the bottom of the fixed base, two sets of springs fixedly connected to the bottom of the support frame, a shock absorber fixedly connected to the bottom of each set of springs, a guide component provided on the top of the shock absorber, two rotating shafts rotatably connected inside the two shock absorbers, two traveling wheels detachably connected to the outer wall of the rotating shafts, a fixed component provided on the traveling wheels, a battery box fixedly connected to the top of the fixed base, a snap-fit ​​plate fixedly connected to the top of the battery box, two concave plates snapped around the perimeter of the snap-fit ​​plate, a rotating shaft rotatably connected inside the two concave plates, and a warning component provided on the top of one of the concave plates.

[0016] The base of the fixed warning panel one has a built-in damping fixing shaft, which supports the folding of the warning panel two. The fixing shaft serves as the rotation fulcrum of the warning panel two. The warning panel one serves as the main warning panel, and when unfolded, it forms a triangular warning area with the warning panel two.

[0017] As a further description of the above technical solution:

[0018] Warning plates two are rotatably connected to the outer walls of the two fixed shafts on both sides of the warning plate one. A flower screw is threaded through the opposite side of the two warning plates two, and a flower nut is threaded to the outer wall of the flower screw.

[0019] Warning panel 2 serves as a secondary panel, and is locked in the unfolded state by a spiral screw and a spiral nut.

[0020] As a further description of the above technical solution:

[0021] Reflective strips are fixedly installed on both sides of both the second and first warning boards.

[0030] 1. Compared with existing technologies, this railway construction safety protection and early warning device, through the combined use of structures such as snap-fit ​​plates, concave plates, rotating shafts and warning components, allows the warning plate to be unfolded and fixed with simple operation, enhancing the visibility and safety of the device at the construction site. At the same time, when not in use, the warning device can be folded and stored, reducing the storage space occupied and the transportation volume, which not only reduces transportation costs but also effectively reduces the risk of collision or external damage during transportation.

[0031] 2. Compared with existing technologies, this railway construction safety protection and early warning device, through the coordinated use of structures such as springs, shock absorbers, fixed components, and rotating shafts, can effectively buffer vibrations when the equipment encounters joints or track settlement during movement.

The traveling wheels 6 are the core walking components that move along the track. The battery box 7 contains a high-capacity lithium battery pack to power the warning light 22, the alarm 23, and the camera 24. The snap-fit ​​plate 8 is welded to the top of the battery box 7, with a slot on the edge for fixing the protrusions of the concave plate 9. The concave plate 9 is the base for the folding warning component, and can be unfolded or folded up for storage via the rotating shaft 10. Through the coordinated use of the snap-fit ​​plate 8, the concave plate 9, the rotating shaft 10, and the warning component, the warning plate can be unfolded and fixed with simple operation, enhancing the visibility and safety of the device at the construction site. When not in use, the warning device can be folded and stored, reducing the storage space occupied and the transportation volume. This not only reduces transportation costs but also effectively reduces the risk of collision or external damage during transportation.

[0042] The guide assembly includes two guide rods 11 fixedly installed on the top of the shock absorber 4. A limiting disc 12 is fixedly connected to the top of the guide rod 11.

[0043] The fixing component includes a fixing ring 13 fixedly installed on one side of the driving wheel 6. Several fixing bolts 14 slide through the inside of the fixing ring 13. The outer wall of the fixing bolts 14 is adapted to the threaded hole opened on the rotating shaft 5. The fixing ring 13 is embedded with a rubber gasket to prevent the bolts from loosening.

[0044] The warning assembly includes two storage seats 15 fixedly mounted on the top of one of the concave plates 9. A fixing shaft 16 is fixedly connected to one side of each of the two storage seats 15. A warning plate 17 is fixedly connected to the outer wall of each of the two fixing shafts 16. The base of the warning plate 17 has a built-in damping fixing shaft 16, supporting the folding of the warning plate 2 18. The fixing shaft 16 serves as the rotation fulcrum of the warning plate 2 18. The warning plate 17 serves as the main warning panel, forming a triangular warning area with the warning plate 2 18 when unfolded. The two fixing shafts 16... Warning plates 18 are rotatably connected to the outer wall of warning plate 17 on both sides. A threaded screw 19 is threaded through the opposite side of the two warning plates 18. A nut 20 is threaded to the outer wall of the threaded screw 19. The warning plate 18 serves as a secondary panel and is locked in the unfolded state by the threaded screw 19 and the nut 20. Reflective strips 21 are fixedly installed on both sides of warning plates 18 and warning plates 17. The reflective strips 21 provide visual warning to alert construction workers and passing train drivers to the construction area.

[0045] A warning light 22 is fixedly installed on one side of the battery box 7 to serve as a strong visual warning signal, especially in low visibility conditions such as at night or in severe weather conditions, to enhance the warning effect.

[0046] An alarm 23 is installed on the front of the battery box 7, and a camera 24 is fixedly installed on the top of the battery box 7.

The camera 24 is used to monitor the construction area or railway conditions in real time, capture relevant images, and transmit them to the monitoring center in real time to provide real-time data for management personnel.

[0047] Working principle: When encountering a track gauge different from my country's standard track gauge, such as a narrow gauge, the fixing bolt 14 can be rotated with a tool to release it from the fixing ring 13, allowing the traveling wheel 6 to move on the rotating shaft 5. Then, the fixing ring 13 on the traveling wheel 6 is aligned with the threaded hole on the rotating shaft 5, and the fixing bolt 14 is screwed into the threaded hole to achieve the required track gauge. The device can then be placed on the railway construction track and moved along the railway track, improving the adaptability and versatility of the equipment. When the device encounters a track with large joints or a subsided track during movement, the fixing seat 1 will be pressed down due to the bumps and vibrations, thus pushing the fixing seat 1 to move down synchronously and compressing the spring 3, causing it to deform, thereby reducing the vibration of the device. The fixing seat 1 will also slide along the internal guide rod 11 to ensure stable movement, thereby reducing the impact of vibrations during railway construction on the device, extending the service life of the equipment and improving its stability.

[0048] Then, when a warning is needed, the two concave plates 9 can be rotated to form a cross shape. The concave plates 9 are then pressed down, allowing them to engage with the four edges of the locking plate 8 via the bottom protrusions. The two warning plates 18 are then lifted and rotated from the fixed shaft 16, forming a triangular shape with the first warning plate 17 and the two second warning plates 18. At this point, the worker can pass the threaded rod 19 through the two second warning plates 18 and screw the threaded nut 20 onto the threaded rod 19, thus achieving the warning function. When not in use... The flower nut 20 can be removed by reverse screwing, and then the flower screw 19 can be removed. The two warning plates 18 can be rotated relative to each other so that they are located on both sides of the warning plate 18. Then, the concave plate 9 can be moved to release it from the locking plate 8. After that, the concave plate 9 can be rotated to make it overlap. The warning device can be easily stored and folded, reducing the space occupied during storage and reducing the volume during transportation. It can also effectively reduce the risk of damage caused by collision or external force, reduce the difficulty of manual handling, and improve work efficiency.

[0049] 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.
