[0032] See also Figures 1 to 9 A tunnel lighting device for a high-speed tunnel comprises a shell 1, a fixing member 2 is fixedly installed on the rear end face of the shell 1, the fixing member 2 is fixedly connected to the inside of the tunnel, a sleeve shell 3 is sleeved on the outer surface of the shell 1, a lighting compensation lamp 4 is fixedly installed on the front end face of the sleeve shell 3, a motor 5 is fixedly installed on the rear end face of the shell 1, a preliminary fixing mechanism is arranged inside the shell 1, a secondary reinforcement mechanism is arranged inside the preliminary fixing mechanism, a connection and stabilization mechanism is arranged outside the secondary reinforcement mechanism, a snap-fit fixing mechanism is arranged between the sleeve shell 3 and the shell 1, the preliminary fixing mechanism comprises a threaded rod 6 rotatably connected inside the shell 1, a threaded sleeve 7 is spirally connected to the rear side of the outer surface of the threaded rod 6, a connecting rod 8 is rotatably connected to the outer surface of the threaded sleeve 7, a threaded sleeve 9 is spirally connected to the front side of the outer surface of the threaded rod 6, and a connecting rod 10 is rotatably connected to the outer surface of the threaded sleeve 9.
[0033] A slide groove is provided on the outer surface of the shell 1, and a top block 13 is slidably connected inside the slide groove. The rear end of the top block 13 is rotatably connected to a second shaft 12, and the second shaft 12 is fixedly connected to the connecting rod 1 8. The front end of the top block 13 is rotatably connected to a second shaft 11, and the second shaft 11 is fixedly connected to the connecting rod 10.
[0034] A rectangular block 14 is fixedly installed on the upper end of the top block 13, a slot 15 is opened on the upper end of the rectangular block 14, a fixing ring 33 is fixedly installed on the inner wall of the sleeve shell 3, and a plug rod 16 is fixedly installed on the inner wall of the fixing ring 33 corresponding to the slot 15.
[0035] When it is necessary to install the lighting compensation lamp 4 in the tunnel, due to the special requirements of the environment, it is necessary to install it quickly. First, the sleeve 3 on the lighting compensation lamp 4 is placed on the outer shell 1 and abutted against the limit ring 30. Then, the motor 5 is started to rotate the threaded rod 6. The thread groove on the outer surface of the threaded rod 6 is a bidirectional thread groove. Therefore, when the threaded rod 6 rotates, the threaded sleeve 1 7 and the threaded sleeve 2 9 connected by the spiral transmission on the outer surface of the threaded rod 6 will move toward each other, and the threaded sleeve 1 7 carries the connecting rod 1 8 to move, and the threaded sleeve 2 9 carries The connecting rod 10 is displaced, the rotating shaft 12 on the connecting rod 1 8 is rotatably connected to the top block 13, and the rotating shaft 11 on the connecting rod 10 is also rotatably connected to the top block 13. Therefore, with the cooperation of the connecting rod 1 8 and the connecting rod 10, the top block 13 will be driven toward the casing 3, and the rectangular block 14 on the top block 13 will be displaced synchronously, so that the insertion rod 16 on the fixing ring 33 is inserted into the slot 15 on the rectangular block 14, and the three groups of insertion rods 16 are synchronously inserted into the corresponding slots 15, so as to preliminarily fix and install the casing 3.
[0036] The secondary fixing mechanism includes a transmission rod 17 fixedly installed at both ends of the rotating shaft 12, and a clamping shaft 18 fixedly installed at the other end of the transmission rod 17. A clamping groove 19 is opened inside the rectangular block 14 corresponding to the clamping shaft 18, and a clamping groove 20 is opened on the outer surface of the insertion rod 16 corresponding to the clamping groove 19.
[0037] Secondly, when the upper end of the connecting rod 1 8 carries the rotating shaft 2 12 to move, the transmission rod 17 on the rotating shaft 2 12 is synchronously displaced and deflected, and carries the card shaft 18 to slide into the card slot 1 19 and the card slot 2 20, and the insertion rod 1 16 and the rectangular block 14 are fixed for a second time, thereby enhancing the installation stability between the sleeve 3 and the outer shell 1.
[0038] The installation and replacement of lighting fixtures is a task that requires high caution. Due to the particularity of the working environment, maintenance operations usually require blocking half of the lane to ensure the safety of the staff. However, on the highway, any traffic interruption may bring safety hazards and efficiency losses. Therefore, shortening the replacement time of lamps can not only improve work efficiency, but also significantly improve the level of road safety and reduce the risk of traffic accidents. Therefore, this solution sets up a primary fixing mechanism and a secondary fixing mechanism to make the installation and removal process of the lamps fast and simple, greatly improving work efficiency. At the same time, the two-level fixing method significantly enhances the stability of the lamps, ensuring that safe and reliable lighting can be provided in various environments, extending the service life of the lamps and reducing maintenance costs.
[0039] The connection stabilization mechanism includes gears 21 fixedly installed at both ends of the rotating shaft 11, a transmission frame 22 is sleeved on the outer surface of the rectangular block 14, the transmission frame 22 is slidably connected to the rectangular block 14, and a rack 23 is fixedly installed on the rear end surface of the transmission frame 22, and the rack 23 is meshed with the gear 21.
[0040] An airbag 24 is fixedly installed between the transmission frame 22 and the top block 13, and a second plug rod 26 is fixedly installed on the upper end surface of the transmission frame 22. A second slot 34 is provided inside the rectangular block 14 and the first plug rod 16 corresponding to the second plug rod 26. A storage cavity 27 is provided at the upper end of the second plug rod 26, and a connecting pipe 25 is provided between the airbag 24 and the storage cavity 27.
[0041] Telescopic rods 28 are slidably connected to both sides of the storage cavity 27 , and a clamping groove 29 is formed at the end of the clamping shaft 18 corresponding to the telescopic rods 28 .
[0042] Secondly, when the upper end of the connecting rod 2 10 carries the rotating shaft 11 to move, the gear 21 on the rotating shaft 11 deflects synchronously, and the gear 21 meshes with the rack 23 on the transmission frame 22. Therefore, when the gear 21 deflects, it will drive the transmission frame 22 to rise. An airbag 24 is fixedly installed between the transmission frame 22 and the top block 13, which then squeezes the airbag 24, so that the gas inside the airbag 24 enters the storage chamber 27 through the connecting pipe 25. When the transmission frame 22 rises, the insertion rod 26 will rise synchronously and be inserted into the inside of the slot 2 34. When the gas enters the storage chamber 27, the telescopic rod 28 inside the storage chamber 27 will be pushed out, and then inserted into the card slot three 29 on the card shaft 18, so that the preliminary fixing mechanism and the secondary reinforcement mechanism form a stable whole under the action of the connecting stabilization mechanism.
[0043] The clamping and fixing mechanism comprises a limiting ring 30 fixedly mounted on the outer surface of the housing 1 , a clamping plate 31 fixedly mounted on the end of the transmission rod 17 , and a groove 32 is formed on the rear end surface of the clamping plate 31 corresponding to the fixing ring 33 .
[0044] There are three corresponding groups of connecting rod 1 8 , connecting rod 2 10 , top block 13 , rectangular block 14 , plug rod 1 16 and slot 15 , which are dispersedly arranged in a ring shape. The three groups of connecting rod 1 8 are rotatably connected to threaded sleeve 1 7 , and the three groups of connecting rod 2 10 are rotatably connected to threaded sleeve 2 9 .
[0045] The secondary reinforcement mechanism, the connection stabilization mechanism and the clamping and fixing mechanism are respectively provided in three groups and are dispersedly arranged in a ring shape.
[0046] This solution integrates the primary and secondary fixing mechanisms into one by setting up a connection stabilization mechanism and a snap-fit fixing mechanism, which significantly enhances the stability of the equipment. The precise positioning of the snap-fit fixing device achieves the final safety locking, providing reliable operation guarantee, which is suitable for various application scenarios that require high stability and ensures long-term operation without any worries.
[0047] When the transmission rod 17 deflects, the card plate 31 will be deflected synchronously, the groove 32 on the card plate 31 will be clamped on the fixing ring 33, and the limiting ring 30 will be used to further fix and limit the housing 3 to improve stability, so that the fixed installation of the lighting compensation lamp 4 can be completed.
[0048] Directions:
[0049] When it is necessary to install the lighting compensation lamp 4 in the tunnel, due to the special requirements of the environment, it is necessary to install it quickly. First, the sleeve 3 on the lighting compensation lamp 4 is placed on the outer shell 1 and abutted against the limit ring 30. Then, the motor 5 is started to rotate the threaded rod 6. The thread groove on the outer surface of the threaded rod 6 is a bidirectional thread groove. Therefore, when the threaded rod 6 rotates, the threaded sleeve 1 7 and the threaded sleeve 2 9 connected by the spiral transmission on the outer surface of the threaded rod 6 will move toward each other, and the threaded sleeve 1 7 carries the connecting rod 1 8 to move, and the threaded sleeve 2 9 carries The connecting rod 10 is displaced, the rotating shaft 12 on the connecting rod 1 8 is rotatably connected to the top block 13, and the rotating shaft 11 on the connecting rod 10 is also rotatably connected to the top block 13. Therefore, under the cooperation of the connecting rod 1 8 and the connecting rod 10, the top block 13 is driven toward the casing 3, and the rectangular block 14 on the top block 13 is displaced synchronously, so that the insertion rod 16 on the fixing ring 33 is inserted into the slot 15 on the rectangular block 14, and the three groups of insertion rods 16 are synchronously inserted into the corresponding slots 15, so as to preliminarily fix and install the casing 3;
[0050] Secondly, when the upper end of the connecting rod 1 8 carries the rotating shaft 2 12 to move, the transmission rod 17 on the rotating shaft 2 12 moves synchronously and deflects, and carries the card shaft 18 to slide into the card slot 1 19 and the card slot 2 20, and the insertion rod 1 16 and the rectangular block 14 are fixed for a second time, thereby enhancing the installation stability between the sleeve 3 and the outer shell 1;
[0051] Secondly, when the upper end of the connecting rod 2 10 carries the rotating shaft 1 1 to move, the gear 21 on the rotating shaft 1 1 is synchronously deflected, and the gear 21 is meshed with the rack 23 on the transmission frame 22. Therefore, when the gear 21 is deflected, the transmission frame 22 is driven to rise. An air bag 24 is fixedly installed between the transmission frame 22 and the top block 13, and then the air bag 24 is squeezed, so that the gas inside the air bag 24 enters the storage chamber 27 through the connecting pipe 25. When the transmission frame 22 rises, the plug rod 26 will rise synchronously and be inserted into the inside of the slot 2 34. When the gas enters the storage chamber 27, the telescopic rod 28 inside the storage chamber 27 will be pushed out, and then inserted into the card slot 3 29 on the card shaft 18, so that the preliminary fixing mechanism and the secondary reinforcement mechanism form a stable whole under the action of the connection stabilization mechanism;
[0052] Secondly, when the transmission rod 17 deflects, the card plate 31 will be deflected synchronously, the groove 32 on the card plate 31 will be stuck on the fixing ring 33, and the limiting ring 30 will be used to further fix and limit the housing 3 to improve stability, so that the fixed installation of the lighting compensation lamp 4 can be completed.
[0053] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
