Description

Technical Field

[0001] This utility model relates to the field of monitoring brackets, specifically a high-speed tunnel monitoring bracket. Background Technology

[0002] High-speed tunnels are passage structures built on highways to pass through mountains, underground or special terrains. They play an important role in shortening travel distances, improving transportation efficiency and protecting the ecological environment. High-speed tunnel monitoring brackets are key structural components used to install and fix various monitoring equipment during tunnel operation.

[0003] However, existing monitoring brackets typically use bolts to fix the monitors. Due to the continuous vibration generated by vehicles passing through the high-speed tunnel, the vibration is transmitted through the bracket to the bolt connection, causing the thread preload to gradually lose. This can lead to the monitor's position shifting, resulting in excessive measurement errors, or even the equipment falling off and damaging vehicles. Utility Model Content

[0024] 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 scope of protection of the present utility model.

[0025] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0026] This application discloses a high-speed tunnel monitoring bracket. (Refer to...) Figure 1 , Figure 5 and Figure 6 A high-speed tunnel monitoring bracket includes a fixing plate 1, which is fixedly connected to the wall by chemical anchors. A bracket body 3 is fixedly connected to the left side of the fixing plate 1, and a connecting mechanism 2 is installed on the top of the bracket body 3.

[0027] The connecting mechanism 2 includes a connecting frame 201. The top of the connecting frame 201 has an inclined surface. The bottom of the connecting frame 201 is slidably connected to the top of the support body 3. A connecting plate 205 is attached to the top of the connecting frame 201. A camera 202 is fixedly connected to the top of the connecting plate 205. An elastic block 206 is fixedly connected to the bottom of the connecting plate 205. The surface of the elastic block 206 engages with the inner cavity of the connecting frame 201. The elastic block 206 is made of thermoplastic polyester elastomer. The elastic block 206, made of thermoplastic polyester elastomer, combines elasticity and temperature resistance, effectively resisting erosion from moisture inside the tunnel. It also has fatigue resistance, maintaining its overall shape even after prolonged use, thus enhancing the elasticity of the locking mechanism. The lifespan of the 206 is extended, reducing the frequency of replacement of the elastic clip 206. When installing the camera 202, the operator holds the camera 202 and moves it downwards. The movement of the camera 202 drives the connecting plate 205 to move, so that the bottom of the connecting plate 205 is attached to the top of the connecting frame 201. During the movement of the connecting plate 205, the elastic clip 206 is also moved. After the connecting plate 205 is in place, the surface of the elastic clip 206 will engage with the inside of the connecting frame 201, thus stably fixing the camera 202 to the top of the bracket body 3. The fixation by the elastic clip 206 can effectively avoid the loosening caused by the continuous vibration of vehicles passing through the high-speed tunnel, ensuring the stability of the camera 202 during use.

[0028] Reference Figure 5 and Figure 6 Positioning rods 204 are fixedly connected to both sides of the bottom of the connecting plate 205. The surface of the positioning rods 204 is slidably connected to the inner cavity of the connecting frame 201. The positioning rods 204 guide the movement of the connecting plate 205, so that the connecting plate 205 can be stably attached to the top of the connecting frame 201, avoiding the position of the connecting plate 205 from shifting during the movement and reducing the installation efficiency of the connecting plate 205.

[0029] Reference Figure 5 and Figure 6 A positioning seat 210 is fixedly connected to the bottom of the inner cavity of the connecting frame 201. The inner cavity of the positioning seat 210 is inserted into the bottom of the surface of the positioning rod 204. The positioning seat 210 is made of polyurethane. The positioning seat 210, made of polyurethane, has high damping and temperature resistance, which can ensure the effective positioning of the positioning rod 204. The positioning seat 210 plays a positioning role in the position of the positioning rod 204, increases the friction force on the positioning rod 204, thereby improving the fixing effect of the connecting plate 205 and preventing the connecting plate 205 from shaking at the top of the connecting frame 201.

[0030] Reference Figure 5 and Figure 6The back of the connecting frame 201 is in contact with a handle 203. There are two handles 203. The front of the handle 203 is fixedly connected to a limiting rod 207. The surface of the limiting rod 207 is inserted into the inner cavity of the positioning rod 204. By setting the limiting rod 207, the position of the positioning rod 204 can be fixed, preventing the positioning rod 204 from detaching from the inside of the positioning seat 210 during use, further improving the stability of the camera 202 during use, and preventing the camera 202 from falling.

[0031] Reference Figure 5 and Figure 6 A limiting ring 208 is fixedly connected to the surface of the limiting rod 207. The front side of the limiting ring 208 contacts the surface of the positioning rod 204. A spring 209 is fixedly connected to the back side of the limiting ring 208. One end of the spring 209 is fixedly connected to the inner cavity of the connecting frame 201. The limiting ring 208 restricts the movement of the limiting rod 207, preventing the limiting rod 207 from detaching from the inside of the connecting frame 201 during movement, which could cause the limiting rod 207 to fall and potentially endanger passing vehicles. At the same time, the spring 209 positions the limiting ring 208. When the handle 203 is not under force, the spring 209 restores its deformation and drives the limiting ring 208 to move, allowing the limiting rod 207 to quickly reset. This facilitates the insertion of the surface of the limiting rod 207 into the inside of the positioning rod 204 for fixation.

[0032] Reference Figure 2 and Figure 3 A rotating wheel 4 is rotatably connected to the back side of the bracket body 3. A worm gear 11 is fixedly connected to the front side of the rotating wheel 4. A worm wheel 12 is meshed with the top of the surface of the worm gear 11. A lead screw 10 is fixedly connected to the inner cavity of the worm wheel 12. A movable plate 8 is threadedly connected to the surface of the lead screw 10. The top of the movable plate 8 is fixedly connected to the bottom of the connecting frame 201. Through the setting of the rotating wheel 4, the worm gear 11 can be driven to rotate during rotation. The rotation of the worm gear 11 can drive the worm wheel 12 to rotate. The rotation of the worm wheel 12 can drive the lead screw 10 to rotate. The rotation of the lead screw 10 can drive the movable plate 8 to move. In turn, the connecting frame 201 can be moved on the top of the bracket body 3 to adjust the position of the connecting frame 201, so as to facilitate the adjustment of the position of the camera 202 and allow the camera 202 to be adjusted to the actual needs of installation.

[0033] Reference Figure 3 and Figure 4The inner cavity of the bracket body 3 is provided with a movable groove 7, and the inner cavity of the movable groove 7 is slidably connected to the surface of the movable plate 8. A baffle 5 is fixedly connected to the top of the inner cavity of the movable groove 7, and the surface of the baffle 5 is slidably connected to the inner cavity of the movable plate 8. Guide grooves 6 are provided on the front and back sides of the inner cavity of the movable groove 7, and guide plates 9 are slidably connected to the inner cavity of the guide grooves 6. One side of the guide plate 9 is fixedly connected to the surface of the movable plate 8. The baffle 5 provides a sealing function for the interior of the movable groove 7, preventing foreign objects from entering the interior of the movable groove 7 and avoiding affecting the movement of the movable plate 8. At the same time, the guide groove 6 allows the guide plate 9 to slide inside the bracket body 3, thereby guiding the movement of the movable plate 8, improving the stability of the movable plate 8 during movement, keeping the movable plate 8 moving horizontally, preventing the position of the movable plate 8 from shifting during movement, and avoiding deviation in the position of the camera 202.

[0034] Working Principle: When installing the camera 202, the operator holds the camera 202 and moves it downwards. This movement of the camera 202 moves the connecting plate 205, causing its bottom to adhere to the top of the connecting frame 201. The movement of the connecting plate 205 also moves the positioning rod 204, guiding its movement and ensuring a stable fit between the connecting plate 205 and the top of the connecting frame 201, preventing positional shifts. The movement of the connecting plate 205 also moves the elastic locking block 206. After the connecting plate 205 is in place, the surface of the positioning rod 204 inserts into the positioning seat 210. The positioning seat 210 increases the friction on the positioning rod 204, improving its positioning effect and thus enhancing the fixation of the connecting plate 205. During the movement of the positioning rod 204, the handle 203 is pulled to move it. The movement of the handle 203 drives the limiting rod 207 to move, adjusting the position of the limiting rod 207 to avoid obstructing the movement of the positioning rod 204. After the positioning rod 204 is in place, the handle 203 is released, and the spring 209 restores its deformation, causing the limiting rod 207 to quickly reset. The surface of the limiting rod 207 is inserted into the interior of the positioning rod 204 to fix the position of the positioning rod 204, preventing it from detaching from the interior of the positioning seat 210 during use. Finally, the surface of the elastic block 206 is engaged with the interior of the connecting frame 201, thus stably fixing the camera 202 to the top of the bracket body 3. The fixation by the elastic block 206 effectively avoids the loosening caused by the continuous vibration of vehicles passing through the high-speed tunnel, ensuring the stability of the camera 202 during use.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
