Description

Technical Field

[0001] The invention relates to the technical field of coal mine transportation, and in particular to a railway signal device. Background Art

[0002] The signal device in the coal mine transportation process is a key component to ensure the safety of coal mine railway transportation. It is mainly used to command and control the train operation and prevent accidents. For example, the signal point light source, which is the most common signal device, uses different colors of lights (such as red, green, and yellow) to indicate the status of the train, such as parking, driving, or deceleration. However, the signal point light source in the related technology is set beside the track. After it is fixed, it is difficult to adjust it according to the specific situation, resulting in poor adaptability and potential safety hazards. Summary of the invention

[0003] The present invention is based on the inventor's discovery and understanding of the following facts and problems:

[0004] Poor adaptability: Different coal mine railway environments may have different terrain and sight conditions. Fixed-height signal point light sources may not be able to adapt to all situations, resulting in signals not being clearly visible in certain locations.

[0005] Line of sight obstruction: If the height of the signal point light source is not appropriate, it may be blocked by surrounding environmental factors (such as trees, buildings, terrain, etc.), affecting the visibility of the signal.

[0006] Distance limitation: a signal point light source at a fixed height may only be clearly seen within a certain distance. For train drivers at long distances, the signal may not be obvious enough.

[0007] The environmental adaptability is weak. The coal mine environment may be changeable. Under severe weather conditions such as fog, rain, snow, etc., the fixed height of the signal point light source may reduce the signal recognition.

[0008] Difficult maintenance: If the height of the signal point light source is not suitable, additional structures or equipment may be required for maintenance and inspection, increasing the difficulty and cost of maintenance.

[0009] Safety hazards: Due to poor signal visibility, drivers may misunderstand the signals and take incorrect actions, increasing safety risks during transportation.

DETAILED DESCRIPTION

[0037] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0038] The railway signaling device according to the embodiment of the present invention will be described below with reference to the accompanying drawings.

[0039] like Figures 1 to 3 As shown, the railway signal device according to the embodiment of the present invention comprises: a base 1, an adjustment component, a signal lamp body 2 and a power supply component.

[0040] The base 1 is used for installation on the ground. The base 1 is square, and the base 1 is arranged horizontally. The four corners of the base 1 are respectively provided with installation holes 101 for installing connection parts such as anchor bolts.

[0041] The adjusting assembly is arranged on the base 1, and comprises a driving part, a transmission part and a moving part which are connected in sequence. The driving part operates to drive the transmission part to move, and the transmission part drives the moving part to move in the vertical direction.

[0042] The signal lamp body 2 is connected to the moving part, so that the moving part moves and drives the signal lamp body 2 to move, thereby realizing the height adjustment of the signal lamp body 2.

[0043] The power supply assembly is electrically connected to the driving part and the signal light body 2, and is used to supply power to the driving part and the signal light body 2, so that the driving part operates and the signal light body 2 emits light.

[0044] Therefore, the railway signal device of the embodiment of the present invention uses the adjustment component to adjust the height of the signal lamp body 2 to ensure the flexibility and reliability of the signal system, thereby improving the safety and efficiency of the coal mine transportation railway.

[0045] For example, by adjusting the height of the signal light source, it can be ensured that the light beam will not be blocked by the surrounding environment (such as terrain, buildings, trees, etc.) along the railway, ensuring that drivers and signalmen can clearly see the signal.

[0046] The signal lights of coal mine transportation railways need to cover different distances. By adjusting the height of the signal light source, it can adapt to different viewing distances so that drivers far away can also receive the signal.

[0047] The height adjustment of the signal light source helps improve the recognition of the signal. For example, a signal light that is too high or too low may be confused with other types of signals, and proper adjustment can help avoid this confusion.

[0048] Coal mine transportation railways may pass through different terrains and climate environments. The height adjustment of the signal light source can adapt to these environmental changes, such as fog, rain, snow, etc., to ensure the visibility of the signal.

[0049] In high-risk areas such as coal mines, the safety of railway transportation is of vital importance. The height adjustment of signal light sources can reduce misunderstandings and accidents caused by unclear signals and improve the safety of transportation.

[0050] In some embodiments, Figures 1 to 3 As shown, the transmission part includes: a cylinder 3, a screw rod 4 and a sliding rod 6.

[0051] The column 3 is arranged in the vertical direction, and the lower end of the column 3 is connected to the upper end surface of the base 1 by welding. A guide groove 301 is provided on the peripheral wall of the column 3, and the guide groove 301 extends along the axial direction of the column 3. The screw rod 4 is located in the column 3 and the central axes of the two are coaxially arranged. The screw rod 4 is rotatably connected to the column 3 through a sleeve bearing, and a ball nut 5 is sleeved on the screw rod 4.

[0052] The end of the slide rod 6 is connected to the ball nut 5, and the slide rod 6 passes through the guide groove 301 along the radial direction of the column 3. The peripheral wall of the slide rod 6 contacts the groove wall of the guide groove 301, so that the screw rod 4 rotates and drives the slide rod 6 to move along the extension direction of the guide groove 301 under the restriction of the guide groove 301.

[0053] It is understandable that when the screw rod 4 rotates, the screw rod 4 will normally drive the ball nut 5 to rotate together. However, by providing the guide groove 301 and the slide bar 6, the limiting effect of the guide groove 301 and the slide bar 6 is utilized to prevent the ball nut 5 from rotating, so that it moves along the axial direction of the screw rod 4, thereby driving the slide bar 6 to move.

[0054] Thus, the signal light body 2 is connected to the slide bar 6 , and the screw rod 4 drives the slide bar 6 to move back and forth, thereby adjusting the height of the signal light body 2 .

[0055] Furthermore, if Figures 1 to 3 As shown, the transmission part further includes: a guide column 7 and a reinforcing rib plate 9.

[0056] The guide column 7 is arranged in parallel with the column tube 3, and the end of the guide column 7 is L-shaped, so that the end of the guide column 7 is fixedly connected to the outer peripheral wall of the column tube 3 by welding. A sliding sleeve 8 is sleeved on the guide column 7, and the sliding sleeve 8 can slide along the extension direction of the guide column 7. The reinforcing rib plate 9 is L-shaped, one end of the reinforcing rib plate 9 is connected to the sliding sleeve 8, and the other end of the reinforcing rib plate 9 is connected to the sliding rod 6.

[0057] Therefore, the guide column 7 and the sliding sleeve 8 are used to further limit the rotation of the ball nut 5, so as to improve the feasibility of height adjustment of the signal lamp body 2. In addition, the reinforcing rib plate 9 also serves to increase the reliability of the supporting structure of the signal lamp body 2.

[0058] In some embodiments, Figures 1 to 3As shown, the moving part includes a clamp 10, which is connected to the end of the slide rod 6 extending out of the cylinder 3 by welding, and the signal lamp body 2 is assembled on the clamp 10. The signal lamp body 2 is fixed by the clamp 10, which improves the convenience of disassembly and assembly of the signal lamp body 2.

[0059] Alternatively, if Figures 1 to 3 As shown, there are multiple guide slots 301, slide bars 6, clamps 10 and signal light bodies 2, and they correspond one to one. It is understandable that multiple signal light bodies 2 can increase the intensity and coverage of the light, making the signal more eye-catching and clearly visible to the driver even in poor light or low visibility environments. In addition, multiple signal light bodies 2 provide a redundancy mechanism to ensure that at least one signal light body 2 is working properly, which is very important for critical safety systems.

[0060] In some embodiments, Figures 1 to 3 As shown, the driving part includes a servo motor 11 , which is arranged on the base 1 , and the output shaft of the servo motor 11 is connected to the screw rod 4 .

[0061] Optionally, the servo motor 11 can be arranged directly below the screw rod 4 so that the central axis of the output shaft of the servo motor 11 is coaxially arranged with the central axis of the screw rod 4, and the output shaft of the servo motor 11 is directly connected to the lower end of the screw rod 4, thereby driving the screw rod 4 to rotate.

[0062] Specifically, Figures 1 to 3 As shown, the driving part also includes a first gear 12 and a second gear 13. The first gear 12 is mounted on the output shaft of the servo motor 11, and the second gear 13 is mounted on the screw rod 4. An arc groove is provided on the cylinder 3, and part of the first gear 12 passes through the arc groove and meshes with the second gear 13.

[0063] It is understandable that since the screw rod 4 directly connected to the servo motor 11 may not provide the required speed and torque, the use of gear transmissions of different sizes can meet different work requirements by speeding up or slowing down. In addition, during maintenance, the bearings in the gears are usually replaced to improve the convenience of maintenance.

[0064] In some embodiments, Figures 1 to 3 As shown, the driving part further includes a housing 14 , which is disposed on the base 1 , and the servo motor 11 , the first gear 12 and the lower end of the column 3 are all located in the housing 14 .

[0065] It should be noted that in order to more clearly illustrate the position of the servo motor 11 in the figure, the servo motor 11 is not placed in the housing 14. In practice, the servo motor 11 is enclosed in the housing 14. This protects the servo motor 11 and the gears from being affected by the external environment.

[0066] In some embodiments, Figures 1 to 3 As shown, the power supply assembly includes a protective cover 15 and a photovoltaic panel 16, a battery 17 and a controller 18 connected in sequence.

[0067] The protective cover 15 is in the shape of an umbrella and is disposed at the upper end of the column 3. The protective cover 15 can cover the components below it, thereby playing a role in shielding from rain. The photovoltaic panel 16 is laid on the upper wall of the protective cover 15, and the photovoltaic panel 16 is used to convert solar energy into electrical energy and store it in the battery 17. The battery 17 and the controller 18 are located below the protective cover 15, and the controller 18 is connected to the signal light body 2 and the servo motor 11.

[0068] Therefore, clean energy is used for energy storage and power generation, achieving self-sufficient power generation and improving the economy of the device.
