Description

Technical Field

[0001] This utility model relates to the field of warning light technology, specifically to a warning device for railway tracks. Background Technology

[0002] China has a vast territory, and most long-distance freight is transported by rail, air, and sea. Among these, rail transport is fast and inexpensive, making it the preferred choice for many customers. To improve the safety of goods and personnel during loading and unloading, rail transport requires setting up warning barriers or warning posts in the loading and unloading area.

[0003] Currently, existing technologies for warning devices used on railway tracks include warning lights. By installing multiple sets of warning lights next to the rails, a warning effect is achieved. This operation is convenient and quick. However, since railway transport warning lights are installed in the wild, wild animals often knock over the warning lights, causing damage and affecting their operation, which may lead to incalculable losses later. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a warning device for railway tracks, which aims to solve the problem that wild animals often knock over the warning lights, causing damage to the warning lights and affecting their operation.

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

[0006] A warning device for railway tracks includes a chassis, a column fixedly connected to the top of the chassis, a light box fixedly connected to the top of the column, a signal light fixedly connected to the outside of the light box, a protective cover fixedly connected to the outside of the signal light, a sleeve slidably connected to the bottom end of the column, mounting ears symmetrically fixedly connected to the outside of the sleeve, a guide rod rotatably connected to the outside of the mounting ears, a semi-circular frame rotatably connected to the end of the guide rod away from the mounting ears, a fixing rod fixedly connected to the inside of the semi-circular frame, and a buffer sleeve fixedly connected to the outside of the fixing rod.

[0007] As a preferred embodiment of this utility model, the surface of the chassis is symmetrically provided with sliding grooves, the fixing rod extends into the interior of the sliding grooves and is slidably connected to the sliding grooves, and the bottom end of the semi-arc frame is symmetrically rotatably connected with auxiliary wheels.

[0008] As a preferred embodiment of this utility model, a limiting ring is fixedly connected to the top of the column, and a shock-absorbing spring is sleeved on the outside of the column and located between the sleeve and the limiting ring.

[0009] As a preferred embodiment of this utility model, a fixing sleeve is fixedly connected to the top of the column, a bird spike is fixedly connected to the top of the fixing sleeve, a connecting ring is provided on the outside of the fixing sleeve, and a through groove is formed between the connecting ring and the fixing sleeve.

[0010] As a preferred embodiment of this utility model, the through groove is internally connected with multiple sets of balls, the connecting ring is internally fixedly connected with a toothed ring, the top of the toothed ring is meshed with a gear, and the middle of the gear is fixedly connected with an extension rod.

[0011] As a preferred embodiment of this utility model, the extension rod extends to the outside of the connecting ring and is rotatably connected to the connecting ring. An interference plate is fixedly connected to the end of the extension rod away from the toothed ring, and the surface of the interference plate is coated with a reflective film.

[0012] As a preferred embodiment of this utility model, the reflective film is a PET aluminum-coated reflective film, and the surface of the reflective film is provided with micron-level uneven texture.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. In this utility model, the impact of the buffer sleeve causes the fixed rod to slide and compress the guide rod. At this time, the guide rod is inclined and generates a thrust on the sleeve. The sleeve will compress the shock-absorbing spring. The shock-absorbing spring stores energy through its extension and contraction to relieve the impact force on the buffer sleeve. Then the shock-absorbing spring returns to its original position. This operation is repeated to achieve the buffering effect.

[0015] 2. In this utility model, by unfolding the bird-proof spikes, birds have no foothold, effectively preventing them from approaching the light box. The wind blows the interference plate, causing the gears to mesh on the outside of the gear ring. At the same time, when the largest surface of the interference plate is vertical, the ball bearings rotate on the outside of the through groove, causing the interference plate to revolve. When sunlight shines on its outside through the reflective film, it reflects the light, thus interfering with the birds' vision, and the birds will directly stay away from the overall device.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Example:

[0023] Please see Figures 1-4 This utility model provides a technical solution:

[0024] A warning device for railway tracks includes a chassis 1, a column 2 fixedly connected to the top of the chassis 1, a light box 3 fixedly connected to the top of the column 2, a signal light 4 fixedly connected to the outside of the light box 3, a protective cover 5 fixedly connected to the outside of the signal light 4, a sleeve 6 slidably connected to the bottom of the column 2, mounting ears 7 symmetrically fixedly connected to the outside of the sleeve 6, a guide rod 8 rotatably connected to the outside of the mounting ears 7, a semi-circular frame 9 rotatably connected to the end of the guide rod 8 away from the mounting ears 7, a fixing rod 10 fixedly connected inside the semi-circular frame 9, and a buffer sleeve 11 fixedly connected to the outside of the fixing rod 10. The device is constructed by digging a pre-buried pit in the field and then placing half of the chassis 1 into the pre-buried pit. Inside, concrete is poured around the chassis 1 to secure it firmly in the field. Then, the light box 3 is powered on to turn on the signal light 4 as a warning. The protective cover 5 is designed to protect the signal light 4 and prevent birds from directly colliding with it. When a wild animal on the ground impacts the column 2, it will first impact the buffer sleeve 11. After the buffer sleeve 11 is compressed, it will drive the fixing rod 10 to slide and compress the guide rod 8. The guide rod 8 swings outside the mounting ear 7. At this time, the guide rod 8 is tilted and generates a thrust on the sleeve 6. At the same time, the column 2 limits the sleeve 6, so that the sleeve 6 can move axially on the column 2.

[0025] Furthermore, in this embodiment, the surface of the chassis 1 is symmetrically provided with sliding grooves 12, the fixed rod 10 extends into the interior of the sliding groove 12 and is slidably connected to the sliding groove 12, and the bottom end of the semi-arc frame 9 is symmetrically rotatably connected with auxiliary wheels. The sliding groove 12 limits the fixed rod 10. When the buffer sleeve 11 is impacted, the fixed rod 10 will slide inside the sliding groove 12 and generate a thrust on the semi-arc frame 9. At this time, the auxiliary wheel slides outside the chassis 1 to assist multiple sets of fixed rods 10 to move closer to each other.

[0026] In this embodiment, a limiting ring 13 is fixedly connected to the top of the column 2. A shock-absorbing spring 14 is sleeved on the outside of the column 2 and between the sleeve 6 and the limiting ring 13. As the sleeve 6 rises, the sleeve 6 will squeeze the shock-absorbing spring 14. The shock-absorbing spring 14 stores energy through its extension and contraction to relieve the impact force on the buffer sleeve 11. Then the shock-absorbing spring 14 resets. This operation is repeated to achieve the buffering function.

[0027] Furthermore, in this embodiment, a fixing sleeve 15 is fixedly connected to the top of the column 2, and a bird spike 1501 is fixedly connected to the top of the fixing sleeve 15. A connecting ring 16 is provided on the outside of the fixing sleeve 15, and a through groove 17 is formed between the connecting ring 16 and the fixing sleeve 15. By unfolding the bird spike 1501 to form a fan-shaped array, birds have no foothold, effectively preventing birds from approaching the light box 3.

[0028] Furthermore, in this embodiment, multiple sets of ball bearings 18 are rolled inside the through groove 17, a toothed ring 19 is fixedly connected inside the connecting ring 16, a gear 20 is meshed with the top of the toothed ring 19, an extension rod 21 is fixedly connected to the middle of the gear 20, the extension rod 21 extends to the outside of the connecting ring 16 and is rotatably connected to the connecting ring 16, and an interference plate 22 is fixedly connected to the end of the extension rod 21 away from the toothed ring 19. The surface of the interference plate 22 is coated with a reflective film, which is a PET aluminized reflective film. The surface of the reflective film has a micron-level uneven texture. Since the outdoor area is an open area, The area has ample wind, which blows the interference plate 22, causing the extension rod 21 to rotate. This allows the gear 20 to mesh with the gear ring 19. Simultaneously, when the maximum surface of the interference plate 22 is vertical, the wind blows it, causing the ball bearing 18 to rotate outside the through groove 17, thus making the interference plate 22 revolve. Through the design of the reflective film, sunlight shines on its exterior, reflecting the light and thus interfering with the birds' vision. At the same time, the textured surface of the reflective film creates diffuse reflection when sunlight shines on it, causing the light to reflect from various angles, and the birds will move away from the device.

[0029] In this embodiment, the specific implementation scenario is as follows: a pre-buried pit is dug in the field, then half of the chassis 1 is placed inside the pre-buried pit, and then concrete is poured around it to firmly fix the chassis 1 in the field. Then, the light box 3 is powered on to turn on the signal light 4 as a warning. The design of the protective cover 5 protects the signal light 4 and prevents birds from directly colliding with it. When a wild animal on the ground collides with the column 2, it will first impact the buffer sleeve 11. After the buffer sleeve 11 is compressed, it will drive the fixing rod 10 to slide and compress the guide rod 8. The guide rod 8 swings outside the mounting ear 7. At this time, the guide rod 8 is tilted and generates a thrust on the sleeve 6. At the same time, the column 2 limits the sleeve 6, so that the sleeve 6 moves axially on the column 2. The sleeve 6 will compress the shock-absorbing spring 14. The energy stored by the extension and contraction of the shock-absorbing spring 14 will compress the buffer sleeve 1. The impact force on the light box 1 is dissipated, and then the shock-absorbing spring 14 is reset. This operation is repeated to achieve the buffer function. By unfolding the bird spikes 1501 into a fan-shaped array, birds have no foothold and are effectively prevented from approaching the light box 3. Since the outdoor area is an open area with sufficient wind, the wind blows the interference plate 22. Then the extension rod 21 is rotated so that the gear 20 meshes with the gear ring 19. At the same time, when the maximum surface of the interference plate 22 is vertical, the wind blows it. At this time, the ball bearing 18 rotates outside the through groove 17, so that the interference plate 22 revolves. Through the design of the reflective film, when sunlight shines on its exterior, it will reflect the light, thus interfering with the birds' vision. At the same time, the concave and convex texture designed on the surface of the reflective film forms diffuse reflection when sunlight shines on it. The light is reflected from all angles, and the birds will directly stay away from the overall device.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
