Description
Technical Field
[0001] This utility model relates to the field of safety monitoring and control technology, specifically a railway safety early warning audible and visual alarm. Background Technology
[0002] As a critical national infrastructure, railway transportation relies on the stable operation of various early warning devices along the line for its safe operation. Among them, audible and visual alarms, as "safety sentinels" in scenarios such as level crossings, tunnels, and bridges, need to have high reliability, easy maintenance, and strong environmental adaptability. A review of the publicly disclosed (announcement) number CN220948012U reveals a railway safety early warning audible and visual alarm device. This technology discloses a solution that includes a railway safety audible and visual alarm device assembly. The upper surface of the assembly is fitted with a cleaning component, which solves the problem of excessive dust accumulation on the outer wall of the device after prolonged use, especially in outdoor environments, affecting the transmission of the alarm light and reducing its brightness, thus failing to meet warning requirements. This solution facilitates cleaning of the outer wall of the warning light and ensures light penetration. While the aforementioned applications meet the user's needs to a certain extent, certain shortcomings still exist during use. Specific problems include: the connection between the lampshade and mounting base of railway audible and visual alarms often uses bolt fastening structures, requiring individual tightening with tools such as wrenches. Railway lines are often located in remote environments (such as mountain crossings and desert sections), making it difficult to carry tools. Furthermore, bolts are prone to corrosion due to wind, sand, and rain, significantly increasing disassembly and maintenance time. Uneven bolt tightening can also cause localized stress concentration, leading to loosening under high-frequency train vibrations, requiring regular inspection and re-tightening, thus increasing maintenance costs. Therefore, this utility model designs a railway safety early warning audible and visual alarm to solve the above problems. Utility Model Content

[0016] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.
[0017] Example: Figure 1-5 As shown, this utility model provides a technical solution: a railway safety early warning audible and visual alarm device, including a support column 1 and an audible and visual alarm component 11 installed on the top of the support column 1. The surface of the audible and visual alarm component 11 is provided with a warning lamp cover 2. A mounting base A3 is fixedly connected to the top of the audible and visual alarm component 11. A lamp cover connecting block 21 is fixedly connected to the surface of the warning lamp cover 2. A mounting base connecting block 31 is fixedly connected to the surface of the mounting base A3. A first snap-fit adapter rod 22 is fixedly connected between the lamp cover connecting block 21 and the warning lamp cover 2. A second snap-fit adapter rod 32 is fixedly connected between the mounting base connecting block 31 and the mounting base A3. A first snap-fit adapter groove 23 is formed on the surface of the lamp cover connecting block 21 to cooperate with the second snap-fit adapter rod 32. A second snap-fit adapter groove 33 is formed on the surface of the mounting base connecting block 31 to cooperate with the first snap-fit adapter rod 22.
[0018] In this implementation plan: the support column 1 provides vertical support for the equipment, and the audible and visual alarm component 11 integrates electro-acoustic and electro-optical early warning functions. When installing the warning lamp cover 2, the lamp cover connecting block 21 of the warning lamp cover 2 is pressed down with the lamp cover until the bottom surface of the installed warning lamp cover 2 is in contact with the surface of the mounting base A3. Then, the warning lamp cover 2 is rotated and installed until the first snap-fit adapter rod 22 is inserted into the second snap-fit adapter slot 33 opened on the mounting base connecting block 31 on the mounting base A3. At the same time, the second snap-fit adapter rod 32 on the mounting base connecting block 31 is inserted into the first snap-fit adapter slot 23 opened on the lamp cover connecting block 21, so as to realize the rapid fastening of the warning lamp cover 2 and the mounting base A3, which greatly improves the assembly efficiency.
[0019] Furthermore: In an optional embodiment, the lampshade connecting clip 21, the first snap-fit adapter rod 22, the mounting base connecting clip 31, and the second snap-fit adapter rod 32 are each provided in three sets, and the three sets of the lampshade connecting clip 21, the first snap-fit adapter rod 22, the mounting base connecting clip 31, and the second snap-fit adapter rod 32 are evenly arranged on the surface of the warning lampshade 2 and the mounting base A3.
[0020] In this embodiment: three sets of lamp cover connecting clips 21, first clip adapter rod 22, mounting base connecting clips 31, and second clip adapter rod 32 are distributed at equal angles along the circumference of the warning lamp cover 2 and the mounting base A3. During assembly, each set of clip components is simultaneously rotated and inserted, and the force is evenly distributed to form a triangular stable support, which constrains the radial runout and circumferential torsion of the lamp cover.
[0021] Furthermore: In an optional embodiment, both the end of the first snap-fit adapter 22 away from the lampshade connecting block 21 and the end of the second snap-fit adapter 32 away from the mounting base connecting block 31 are provided with guide slopes 6.
[0022] In this embodiment: During assembly, the guide slope 6 at the end of the first snap-fit adapter rod 22 and the end of the second snap-fit adapter rod 32 first contacts the edges of the first snap-fit adapter groove 23 and the second snap-fit adapter groove 33. The wedge-shaped guide automatically corrects the installation deviation angle and radial misalignment of the lampshade, reducing the installation difficulty. At the same time, the slope contact replaces rigid collision, reducing component wear.
[0023] Furthermore: In an optional embodiment, the bottom end of the warning lamp cover 2 is fixedly connected to a lamp cover positioning boss 4, and the surface of the mounting base A3 is provided with a boss adapter groove 41 that mates with the lamp cover positioning boss 4.
[0024] In this embodiment: the lampshade positioning boss 4 is inserted into the boss adapter groove 41. The radial displacement of the warning lampshade 2 is limited by the geometric adaptation, and the left and right and back and forth swaying is restricted. This provides an initial alignment reference for the snap-fit assembly and ensures that the snap-fit rod is accurately inserted into the groove.
[0025] Furthermore: In an optional embodiment, a linkage plate 5 is slidably connected to the inner surface of the mounting base A3, and five sets of compression springs 51 are fixedly connected to the bottom end of the linkage plate 5. The other end of the compression springs 51 is fixedly connected to the audible and visual alarm component 11.
[0026] In this embodiment: when the lamp cover positioning boss 4 is inserted into the boss adapter groove 41, the linkage plate 5 is pressed down. The linkage plate 5 applies pressure to the compression spring 51, so that the compression spring 51 is compressed and stores mechanical energy. After the snap-fit assembly is installed, the elastic restoring force of the compression spring 51 pushes the linkage plate 5 upward, thereby making the first snap-fit adapter rod 22 and the second snap-fit adapter groove 33, and the second snap-fit adapter rod 32 and the first snap-fit adapter groove 23 fit more tightly, so that the warning lamp cover 2 and the snap-fit surface of the mounting base A3 fit tightly together and eliminate gaps.
[0027] Furthermore: In an optional embodiment, a damper 52 is provided inside the compression spring 51, and the two ends of the damper 52 are fixedly connected to the linkage plate 5 and the audible and visual alarm component 11, respectively.
[0028] In this embodiment, the damper 52 is nested inside the compression spring 51. After the snap-fit is completed, the spring rebounds to provide preload, while the damper 52 suppresses the high-frequency reciprocating vibration of the spring, such as the continuous flutter of a passing train, so that the preload remains stable rather than fluctuating, ensuring that the snap-fit assembly is always in a tight fit.
[0029] Furthermore: In an optional embodiment, a top plate 53 is provided on the surface of the linkage plate 5, and a rotating shaft 54 is fixedly connected to the bottom end of the top plate 53. The top plate 53 is rotatably connected to the linkage plate 5 through the rotating shaft 54.
[0030] In this embodiment: when the warning light cover 2 is rotated and installed, the top plate 53 is driven to rotate on the surface of the linkage plate 5 via the rotating shaft 54, so that the contact between the bottom end of the warning light cover 2 and the linkage plate 5 changes from rigid sliding friction to rotational engagement, thus avoiding surface scratches caused by relative sliding between the two.
[0031] Furthermore: In an optional embodiment, a rubber pad 55 is fixedly connected to the surface of the top plate 53.
[0032] In this embodiment: when the warning light cover 2 is rotated and installed, the rubber pad 55, due to its high coefficient of friction, generates sufficient friction with the lamp cover positioning boss 4, causing the top plate 53 to rotate synchronously with the warning light cover 2 via the rotating shaft 54, thus avoiding scratches on the contact surface caused by relative sliding between the two. At the same time, the rubber pad 55, as a soft pad layer, undergoes elastic deformation when the lamp cover positioning boss 4 is pressed down, buffering the rigid contact pressure between the boss and the top plate 53, filling the small unevenness of the contact surface, and ensuring uniform force transmission without hard impact.
[0033] Furthermore: In an optional embodiment, three sets of limiting blocks 56 are uniformly fixedly connected to the surface of the linkage plate 5, and the surface of the mounting base A3 is provided with a limiting groove 57 that cooperates with the limiting blocks 56.
[0034] In this embodiment: when the warning light cover 2 rotates and drives the top plate 53 to rotate through the rotating shaft 54, the limiting block 56 is radially constrained by the limiting groove 57, which forcibly restricts the rotational freedom of the linkage plate 5, so that it can only slide up and down along the axial direction and cannot rotate synchronously with the top plate 53, ensuring that the compression spring 51 and the damper 52 always only bear axial pressure or tension, and avoid structural deformation caused by torsion.
[0035] Working Principle: Holding the warning light cover 2, align it with the mounting surface of the mounting base A3, aligning the lamp cover positioning boss 4 at the bottom of the warning light cover 2 with the boss adapter groove 41 on the surface of the mounting base A3. Slowly lower the warning light cover 2, allowing the lamp cover positioning boss 4 to insert into the boss adapter groove 41. Through geometric adaptation, the radial swaying, left-right and front-back displacement of the warning light cover 2 is limited, completing the initial alignment. Continue to press down on the warning light cover 2, the bottom of the lamp cover positioning boss 4 contacts the rubber pad 55 on the surface of the linkage plate 5, and pushes the top plate 53 down. The top plate 53 drives the linkage plate 5 to slide down along the inner wall of the mounting base A3 through the rotating shaft 54. The five sets of compression springs 51 at the bottom of the linkage plate 5 are compressed synchronously, converting mechanical energy into elastic potential energy for storage. The damper 52 nested inside the compression spring 51 is compressed with the spring, slowing down the compression speed through the viscous resistance of the internal medium, avoiding rigid impact, and maintaining the downward state. Rotate the warning light cover 2, causing the lamp cover connecting block 21 to rotate synchronously. The first As the mounting bracket 22 rotates, it gradually approaches the second locking adapter groove 33 of the mounting bracket connecting block 31. Simultaneously, the second locking adapter 32 on the mounting bracket connecting block 31 approaches the first locking adapter groove 23 of the lamp cover connecting block 21 until they are fully engaged. Releasing the pressure, the elastic restoring force of the compression spring 51 pushes the linkage plate 5 upwards. The linkage plate 5, through the top plate 53 and the rubber pad 55, presses against the lamp cover positioning boss 4, ensuring a tight fit between the warning lamp cover 2 and the locking surface of the mounting bracket A3. When the gap is eliminated, the damper 52 suppresses the high-frequency reciprocating vibration of the compression spring 51, keeps the preload stable, and ensures that the snap-fit assembly is always in a tight fit. When disassembling, rotate the warning lamp cover 2 in the reverse direction so that the first snap-fit adapter rod 22 and the second snap-fit adapter rod 32 slide out of the corresponding groove, release the circumferential interlock, lift the warning lamp cover 2 upward, the lamp cover positioning boss 4 disengages from the boss adapter groove 41, the compression spring 51 and the damper 52 reset, and the linkage plate 5 moves upward accordingly, completing the disassembly.
[0036] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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 this utility model should be included within the protection scope of this utility model.
