Detailed Implementation
[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figure 1 , 2 As shown in Figures 3, 4, and 5, this utility model provides a technical solution: a tunnel illumination detection device, comprising: a mounting box 1 with mounting holes; an aluminum alloy support rod 2, which is composed of straight and arc-shaped structures for easy integration with the tunnel interior; the support rod 2 is rotatably mounted on the outside of the mounting box 1; and a tunnel illumination detector 3 is fixedly connected to the top of the support rod 2. The tunnel illumination detector 3 is model YG-TBQ9B; a drive assembly is placed inside the mounting box 1, which includes an electric push rod 13 for driving the support rod 2 to rotate and a transmission part; a limiting part is placed inside the mounting box 1, which includes a positioning baffle 7 that slides inside the mounting box 1 for pressing and fixing the support rod 2; a movable baffle 8 is fixedly connected to one side of the bottom of the positioning baffle 7; and a pressing inclined block 16 that presses the positioning baffle 7 to move is raised and lowered at the bottom of the positioning baffle 7; the inclined surface of the pressing inclined block 16 is slidably connected to the movable baffle 8.
[0024] It should be noted that, in this embodiment, the installation box 1 is equipped with a controller and a corresponding wireless receiving module. When the tunnel illumination detector 3 is being inspected, the controller sends a signal to the receiver on the electric push rod 10, causing the electric push rod 10 to move downwards to the squeezing inclined block 16, thus separating the positioning baffle 7 from the support rod 2. Then, the controller sends a signal to the receiver on the electric push rod 2 13. After receiving the signal, the microcontroller parses the command and starts the electric push rod 2 13 to extend. The electric push rod 2 13 drives the support rod 2 to rotate through the transmission part, thereby rotating the support rod 2 to a vertical downward position. In this way, personnel can stand on the corresponding pickup truck bed to inspect and maintain it without the need for lifting the truck or using auxiliary ladders for corresponding high-altitude operations.
[0025] In one embodiment, the transmission unit includes a gear 12 rotatably mounted inside the mounting box 1. The shaft of the gear 12 is fixedly connected to the support rod 2 via a transmission rod. The transmission rod is rotatably connected to the mounting box 1 via a bracket and a bearing. A rack 14 is meshed with the outer side of the gear 12. A vertical slide rod 15 is slidably connected inside the rack 14. The vertical slide rod 15 is fixedly connected to the mounting box 1. The rack 14 is slidably connected to the inner wall of the mounting box 1. An electric push rod 13 is fixedly connected inside the mounting box 1, and the output end of the electric push rod 13 is fixedly connected to the top of the rack 14.
[0026] It should be noted that, in this embodiment, when the support rod 2 is rotated and adjusted, the electric push rod 13 drives the rack 14 to slide along the vertical slide rod 15 and the inner wall of the mounting box 1. The rack 14 drives the gear 12 to rotate, and the gear 12 drives the support rod 2 to rotate, thereby rotating the support rod 2 to a vertically downward position, thereby reducing the height of the climbing operation.
[0027] In one embodiment, the top of the mounting box 1 is provided with a movable slide groove 6, and the positioning baffle 7 is slidably installed in the movable slide groove 6. A limiting block 4 is fixedly connected to the outside of the mounting box 1 to limit the support rod 2. A transverse slide rod 17 is fixedly connected inside the mounting box 1. The positioning baffle 7 is slidably connected to the transverse slide rod 17. A spring 18 is sleeved on the outside of the transverse slide rod 17 to drive the positioning baffle 7 to move toward the support rod 2. A fixed horizontal plate 9 is fixedly connected inside the mounting box 1. An electric push rod 10 is fixedly connected to the bottom of the fixed horizontal plate 9. The output end of the electric push rod 10 is fixedly connected to the extrusion wedge 16. A limiting rod 11 is fixedly connected to the bottom of the extrusion wedge 16 and slidably connected to the fixed horizontal plate 9. A positioning groove 5 that cooperates with the positioning baffle 7 is provided on one side of the support rod 2. The contact surfaces of the positioning groove 5 and the positioning baffle 7 are both provided with a chamfered structure.
[0028] It should be noted that, in this embodiment, when the support rod 2 needs to be rotated, the electric push rod 10 drives the pressing inclined block 16 downward. The inclined surface of the pressing inclined block 16 reduces the pressure on the moving baffle 8. Under the elastic force of the spring 18, the positioning baffle 7 slides along the transverse slide rod 17 and the moving slide groove 6, thereby causing the positioning baffle 7 to be misaligned and separated from the support rod 2, so that the rack 14 and gear 12 can drive the support rod 2 to rotate. When the support rod 2 is positioned, the electric push rod 10 drives the pressing inclined block 16 downward, pressing the inclined surface of the pressing inclined block 16 downward. Block 16 drives the limiting rod 11 to slide in the middle of the fixed horizontal plate 9. By squeezing the inclined surface of the squeezing block 16 and the contact squeezing of the moving baffle 8, the moving baffle 8 drives the positioning baffle 7 to move along the direction of the transverse slide rod 17 and the moving slide groove 6, and compresses the spring 18. Since the contact surfaces of the positioning baffle 7 and the positioning groove 5 are chamfered, the positioning baffle 7 can contact the inner wall of the positioning groove 5, thereby squeezing and fixing the support rod 2 between the positioning baffle 7 and the limiting block 4, thereby preventing the support rod 2 from loosening or swinging due to gear clearance or other reasons during use.
