Description

Technical Field

[0001] This invention belongs to the field of lighting technology, specifically, it relates to a high-intensity emergency lighting fixture for railway emergency rescue vehicles. Background Technology

[0002] As a key piece of equipment for handling emergencies such as track accidents and tunnel collapses, railway emergency rescue vehicles require their high-intensity emergency lighting fixtures to operate reliably in extremely harsh environments. Rescue sites are often accompanied by large amounts of dust, water vapor, severe vibration, and sudden changes in high and low temperatures, and are also characterized by narrow spaces and dense obstacles, placing stringent requirements on the protective performance, adjustment flexibility, and environmental adaptability of the lighting fixtures.

[0003] In existing technologies, emergency lighting fixtures often employ multiple independent drive sources (such as multiple motors controlling the opening, closing, pitch, and horizontal rotation of the protective cover) to achieve protective unlocking and multi-angle adjustment, relying on complex electronic control systems to work together. However, in environments with dust intrusion, continuous vibration, or humidity, electronic components (such as sensors, control modules, and motor interfaces) are prone to short circuits, poor contact, or mechanical jamming, leading to unlocking failure, adjustment stagnation, or even complete paralysis. This severely impacts the efficiency of lighting deployment at rescue sites and delays rescue opportunities. Summary of the Invention

[0004] The purpose of this invention is to provide a high-intensity emergency lighting fixture for railway emergency rescue vehicles, thereby solving the aforementioned technical problems.

[0005] To achieve the above objectives, the present invention provides a high-intensity emergency lighting fixture for railway emergency rescue vehicles, including a base installed on the emergency rescue vehicle.

[0006] A horizontal adjustment mechanism is installed on the base, and at least one positioning seat is provided on the horizontal adjustment mechanism. A searchlight is rotatably installed on the positioning seat. An adjustment roller for unlocking the searchlight is provided on the horizontal adjustment mechanism in the middle of the positioning seat.

An outer cover for protecting the searchlight is installed on the top of the adjustment roller. The outer cover is sleeved with the end face of the searchlight. At least one combination groove is opened on the circumferential side of the adjustment roller. The combination groove is connected to the positioning seat through a guide rod for driving the positioning seat to move vertically to unlock and separate the searchlight from the outer cover.

[0007] The outer cover sidewall is also equipped with a ramp, and the outer cover sidewall is provided with a combination frame. After the searchlight is separated from the outer cover, the ramp squeezes the combination frame, causing the rocker arm installed at the rotation center of the searchlight to deflect, thereby adjusting the searchlight illumination angle.

[0008] Preferably, the base is fixedly provided with a mounting plate, the mounting plate has a mounting groove, the mounting groove is straight and is used to connect the mounting plate to the bottom of the emergency rescue vehicle, and a crossbeam is installed inside the base, the crossbeam is in the shape of a "Z".

[0009] Preferably, the leveling mechanism includes a guide ring fixedly connected to the base, a bracket, and a plate mounted on the bracket;

[0010] The inner wall of the guide ring has an inner groove, and the two ends of the bracket are equipped with outer protrusions. The outer protrusions are slidably disposed in the inner groove. A guide rail is installed on the outer protrusion, and the guide rail is slidably connected to the guide ring. A locking bolt is installed through the guide rail, and the end of the locking bolt abuts against the end of the guide ring to fix the water level position of the bracket. A positioning plate is installed on the outer wall of the guide ring, and the positioning plate is screwed to the base.

[0011] Preferably, the flat plate is connected to the support through several columns, and a fence is installed around the columns, with the top of the fence fitting against the lower surface of the flat plate and the bottom of the fence fitting against the upper surface of the support.

[0012] Preferably, the searchlight has a heat dissipation shell installed on its outer wall, a positioning shaft installed on the side wall of the heat dissipation shell, the positioning shaft being rotatably connected to the positioning seat, and a positioning rod for limiting the horizontal angle of the positioning seat being installed at the bottom of the positioning seat. One end of the positioning rod passes through the bracket and is positioned opposite to the positioning hole on the base.

[0013] Preferably, a sliding plate is installed on the outer wall of the positioning seat, the sliding plate is sleeved on the limiting rod, the bottom of the limiting rod is installed on the bracket, the top of the limiting rod is installed on the bottom of the plate, and a limiting spring is sleeved on the limiting rod. One end of the limiting spring is engaged with the sliding plate, and the other end of the limiting spring is engaged with the bracket.

[0014] Preferably, the inner wall of the outer cover is fitted with a soft pad, the stepper motor is mounted on the bracket, the output end of the stepper motor is fitted with a drive shaft, and the drive shaft passes through the flat plate and is connected to the rotation center of the adjusting roller.

[0015] Preferably, the combined groove includes a horizontal flipping section and an inclined lifting section, which are connected to each other. A sliding rod is installed at the end of the guide rod, and the sliding rod is slidably disposed in the combined groove.

[0016] Preferably, the combined frame includes a timing frame and upright plates installed on both sides of the timing frame. The timing frame is equipped with guide wheels at its ends, and the guide wheels are in contact with the ends of the outer cover. The upright plates have slide rails on their side walls, and push plates are vertically slidably mounted on the slide rails. Push rods are mounted on the push plates, and the push rods are slidably connected to a limiting groove on the side wall of the positioning seat. The limiting groove is a horizontal groove, and the push rods are slidably mounted in a strip groove on the side wall of the rocker arm.

[0017] Preferably, the side wall of the synchronization frame is provided with a accumulator rod, one end of the accumulator rod is installed with a connecting seat, and the connecting seat is installed on the side wall of the positioning seat. The other end of the accumulator rod passes through the synchronization frame and is installed with a limit plate. An accumulator spring is sleeved on the accumulator rod. One end of the accumulator spring is clamped to the side wall of the synchronization frame, and the other end is clamped to the limit plate.

[0018] Therefore, the high-intensity emergency lighting fixture for railway emergency rescue vehicles described above has the following beneficial effects: through the linkage design of protection and unlocking, the outer casing fully encloses the searchlight when not in operation, which can isolate dust and rainwater. When starting, it drives the adjusting roller, which is linked with the lifting groove and the sliding rod to achieve rapid unlocking and separation without manual disassembly, thus balancing safety and emergency response efficiency. At the same time, the pitch angle is converted into motion through the outer casing's inclined compression combination frame; the horizontal angle relies on the rotation structure of the bracket and guide ring to achieve a wide range of rotation and stable locking. The combination of the two eliminates blind spots and covers complex rescue scenarios. Furthermore, the overall mechanical linkage and elastic component collaboration reduce the risk of electronic component failure. The sliding components and locking mechanism ensure stable and reliable operation, are adaptable to harsh environments, and can maintain adjustment accuracy even after long-term use.

[0035] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0036] Example 1

[0037] like Figure 1 As shown, a high-intensity emergency lighting fixture for a railway emergency rescue vehicle includes a base 1 installed on the emergency rescue vehicle. The base 1 secures the fixture to the roof of the emergency rescue vehicle. Figure 2 As shown, the mounting plates 11 around the base 1 are connected to the pre-set mounting positions on the roof by bolts through the straight mounting grooves 111. The elongated design of the mounting grooves 111 can accommodate the hole deviations of different roofs, making it easy to quickly align and fix. At the same time, the zigzag crossbeams 112 inside the base 1 enhance the overall structural strength, resist the vibration and impact during vehicle driving or operation, and prevent the base 1 from deforming and affecting the stability of the lamp.

[0038] A leveling mechanism is installed on the base 1, such as... Figures 3-4 As shown, the horizontal adjustment mechanism includes a guide ring 12, a bracket 13, and a plate 14 fixedly connected to the base. The hierarchical structure of the base 1, bracket 13, and plate 14 provides a stable mounting foundation for each component, facilitating modular assembly. A positioning plate 122 is installed on the outer wall of the guide ring 12, and the positioning plate 122 is bolted to the base 1, enhancing the connection strength between the guide ring 12 and the base 1. The bracket 13 is rotatably disposed inside the guide ring 12. An inner groove 121 is formed on the inner wall of the guide ring 12. Outer protrusions 131 are installed at both ends of the bracket 13, and the outer protrusions 131 are slidably disposed within the inner groove 121. The rotational cooperation between the guide ring 12 and the bracket 13, combined with the sliding limit of the outer protrusions 131 and the inner groove 121, ensures smooth horizontal rotation. A guide rail 132 is mounted on the protrusion 131, and the guide rail 132 is slidably connected to the guide ring 12. A locking bolt 133 is installed through the guide rail 132, and the end of the locking bolt 133 is tightly fitted with the end of the guide ring 12. The cooperation between the guide rail 132 and the locking bolt 133 achieves precise locking of the horizontal angle, improving the reliability of adjustment. Columns 141 are installed at the four corners of the plate 14. The bottom of the columns 141 is connected to the bracket 13. Enclosures 142 are installed around the columns 141, with the top of the enclosures 142 fitting against the lower surface of the plate 14 and the bottom of the enclosures 142 fitting against the upper surface of the bracket 13. The columns 141 increase the connection rigidity between the plate 14 and the bracket 13, enhancing the structural load-bearing capacity. The enclosures 142 form a protective space, reducing interference from external debris to internal components.

[0039] like Figure 5As shown, three positioning seats 22 are inserted into the plate 14. A searchlight 2 is rotatably mounted on the positioning seats 22. An adjusting roller 3 is rotatably mounted on the plate 14. An outer cover 32 for protecting the searchlight is mounted on the top of the adjusting roller 3. A soft pad 321 is installed on the inner wall of the outer cover 32 to buffer the vibration and impact between the outer cover 32 and the searchlight 2, preventing wear of the components. A stepper motor 31 is connected to the bottom of the adjusting roller 3. The stepper motor 31 is mounted on the bracket 13. A drive shaft 311 is installed on the output shaft of the stepper motor 31. The drive shaft 311 passes through the plate 14 and is connected to the rotation center of the adjusting roller 3, realizing the rotation of the adjusting roller 3, providing power for unlocking and angle adjustment, and realizing automatic control.

[0040] like Figure 6 As shown, two parallel combination grooves 33 are formed on the circumference of the adjusting roller 3. The combination grooves 33 are connected to the positioning seat 22 via guide rods 34. They are used to drive the positioning seat 22 to move vertically to unlock and to separate the searchlight 2 from the outer cover 32. The combination grooves 33 include a horizontal flipping section 332 and an inclined lifting section 331, which are connected. A slide rod 341 is installed at the end of the guide rod 34. The slide rod 341 is slidably disposed in the combination grooves 33. The horizontal flipping section 332 and the inclined lifting section 331 cooperate with each other. The sliding of the slide rod 341 realizes the continuous action of unlocking the positioning seat 22 and flipping the searchlight 2. The cooperation between the guide rod 34 and the slide rod 341 ensures that the movement transmission between the adjusting roller 3 and the positioning seat 22 is accurate and reliable.

[0041] like Figure 7 As shown, a heat dissipation shell 21 is installed on the outer wall of the searchlight 2 to improve the heat dissipation efficiency of the searchlight 2 and ensure the stability of high-intensity lighting. A positioning shaft 211 is installed on the side wall of the heat dissipation shell 21. The positioning shaft 211 is rotatably connected to the positioning seat 22. The positioning rod 221 passes through the bracket 13 and is positioned opposite to the positioning hole 222 opened on the base 1. When not in use, the positioning rod 221 is inserted into the positioning hole 222. The insertion and engagement of the positioning rod 221 and the positioning hole 222 enhances the reliability of angle locking in the non-working state. The positioning shaft 211 realizes the rotatable connection between the searchlight 2 and the positioning seat 22, providing a fulcrum for pitch adjustment. A sliding plate 23 is installed on the outer wall of the positioning seat 22. The sliding plate 23 is sleeved on the limiting rod 231. The bottom of the limiting rod 231 is installed on the bracket 13, and the top of the limiting rod 231 is installed on the bottom of the plate 14. A limiting spring 232 is sleeved on the limiting rod 231. One end of the limiting spring 232 is engaged with the sliding plate 23, and the other end of the limiting spring 232 is engaged with the bracket 13. The limiting rod 231 provides guidance for the vertical movement of the positioning seat 22, ensuring smooth movement. The limiting spring 232 assists the positioning seat 22 in resetting through elastic force, enhancing the stability of the structural linkage.

[0042] like Figures 8-9As shown, the outer cover 32 is also equipped with a ramp 4 on its side wall, and a combination frame is provided on the side wall of the outer cover 32. After the searchlight 2 is separated from the outer cover 32, the ramp 4 presses against the combination frame, causing the rocker arm 43 mounted at the rotation center of the searchlight 2 to deflect, thereby adjusting the illumination angle of the searchlight 2. The linkage design of the outer cover 32, ramp 4, combination frame, and rocker arm 43 makes the protection and angle adjustment of the searchlight 2 integrated.

[0043] The assembly frame includes a timing frame 41 and upright plates 42 installed on both sides of the timing frame 41. Guide wheels 411 are installed at the ends of the timing frame 41, and the guide wheels 411 are in contact with the ends of the outer cover 32. A slide rail 422 is provided on the side wall of the upright plate 42, and a push plate 421 is vertically slidably mounted on the slide rail 422. A push rod 432 is installed on the push plate 421, and the push rod 432 is slidably connected to a limiting groove 433 opened on the side wall of the positioning seat 22. The limiting groove 433 is a horizontal groove. The 432 is slidably mounted in the strip groove 431 on the side wall of the rocker arm 43. A accumulator rod 44 is movably mounted through the side wall of the synchronous frame 41. One end of the accumulator rod 44 is fitted with a connecting seat 441, which is mounted on the side wall of the positioning seat 22. The other end of the accumulator rod 44 is fitted with a limit plate 442. A accumulator spring 443 is sleeved on the accumulator rod 44. One end of the accumulator spring 443 is engaged with the side wall of the synchronous frame 41, and the other end is engaged with the limit plate 442. The guide wheel 411 reduces the friction between the synchronous frame 41 and the outer cover 32, improving the smoothness of the linkage. The slide rail 422 cooperates with the push plate 421 to realize the conversion of horizontal movement to vertical movement. Combined with the push rod 432, the strip groove 431 and the rocker arm 43, it precisely drives the tilt adjustment of the searchlight 2. The accumulator spring 443 provides power for the reset of the combined frame, ensuring the repeatability of the angle adjustment.

[0044] The implementation principle of a high-intensity emergency lighting fixture for a railway emergency rescue vehicle in this embodiment is as follows:

[0045] When not in operation or during movement, the lamp is in a protective locking mode. The searchlight 2 is completely covered by the outer cover 32. The soft pad 321 on the inside of the outer cover 32 buffers vibration and prevents the searchlight 2 from directly colliding with the outer cover 32. The outer cover 32 is connected to the flat plate 14 through the adjusting roller 3 to form a closed protective space, blocking dust or rainwater from directly corroding the searchlight 2. The positioning rod 221 at the bottom of the positioning seat 22 is inserted into the positioning hole 222 of the base 1. Together with the limiting spring 232 on the sliding plate 23, the positioning seat 22 and the searchlight 2 are firmly locked at a fixed angle to prevent the angle from shifting due to bumps when the vehicle moves.

[0046] Before turning on the lighting, the fixed state of the searchlight 2 and the outer cover 32 must be unlocked.

[0047] When the stepper motor 31 on the bracket 13 starts, it drives the adjusting roller 3 to rotate through the transmission shaft 311. The inclined lifting section 331 on the side wall of the adjusting roller 3 rotates accordingly. At this time, the slide rod 341 at the end of the guide rod 34 on the side wall of the positioning seat 22 slides in the inclined lifting section 331. Since the inclined lifting section 331 is in an inclined state, it generates an upward lifting force on the slide rod 341, which drives the positioning seat 22 to move upward along the limiting rod 231. The positioning rod 221 is pulled out from the positioning hole 222, releasing the angle lock of the searchlight 2.

[0048] As the positioning seat 22 moves upward, it drives the searchlight 2 to move vertically as a whole, eventually separating the searchlight 2 from the outer cover 32 and completing the unlocking operation. As the adjusting roller 3 continues to rotate, the slide bar 341 moves from the inclined lifting section 331 to the horizontal flipping section 332, at which point the outer cover 32 is completely detached from the searchlight 2.

[0049] At this time, the slope 4 on the side wall of the outer cover 32 begins to squeeze the guide wheel 411 at the end of the synchronous frame 41 of the combined frame, pushing the synchronous frame 41 to move away from the outer cover 32. The upright plates 42 on both sides of the synchronous frame 41 move accordingly. The push plate 421 on the upright plate 42 slides vertically on the slide rail 422. The push rod 432 on the push plate 421 slides along the strip groove 431 on the side wall of the rocker arm 43. At the same time, the push rod 432 slides horizontally in the limiting groove 433 on the side wall of the positioning seat 22, causing the rocker arm 43 to deflect around the rotation center of the searchlight 2, thereby driving the searchlight 2 to adjust the pitch angle with the positioning shaft 211 as the fulcrum. During this process, the storage spring 443 on the storage rod 44 is stretched, providing power for subsequent angle reset.

[0050] To adjust the horizontal angle, loosen the locking bolt 133 on the bracket 13, and push the bracket 13 to rotate within the guide ring 12. The outer protrusion 131 on the side wall of the bracket 13 slides along the inner groove 121 of the guide ring 12. The guide rail 132 ensures smooth rotation. After adjusting to the target angle, tighten the locking bolt 133 so that its end fits tightly against the guide ring 12, thus locking the horizontal angle. After use, loosen the locking bolt 133 on the bracket 13, and push the bracket 13 to rotate within the guide ring 12 so that the bracket 13 returns to its initial position. The stepper motor 31 starts, restoring the fixed state of the searchlight 2 and the outer cover 32. At the same time, the positioning rod 221 inserts into the positioning hole 222, returning to the initial position for protection.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solutions of the present invention, and these modifications or equivalent substitutions cannot cause the modified technical solutions to deviate from the spirit and scope of the technical solutions of the present invention.
