Description

Technical Field

[0001] This utility model relates to the field of tunnel engineering technology, specifically a warning device for tunnel construction that is easy to adjust. Background Technology

[0002] Tunnel engineering refers to structures built underground, underwater, or within mountains to lay railways or construct highways for motor vehicles. Based on their location, they can be divided into three main categories: mountain tunnels, underwater tunnels, and urban tunnels. Mountain tunnels are those that pass under mountains or hills to shorten distances and avoid steep gradients; underwater tunnels pass under rivers or straits to cross them; and urban tunnels are those that pass underground within cities to accommodate railways passing through large urban areas. Among these three types, mountain tunnels are the most commonly constructed. Warning devices are frequently used during tunnel construction.

[0003] The existing utility model with authorization announcement number CN210684532U discloses a warning device for tunnel construction, including a base plate, a support column, a first baffle, and a second baffle. Inclined plates are fixed to both ends of the base plate. Fixing plates are fixed to both sides of the upper surface of the base plate by bolts. Threaded holes adapted to the bolts are provided on both sides of the upper surface of the base plate and on the fixing plates. The bolts pass through the threaded holes on the fixing plates and are screwed into the threaded holes on the upper surface of the base plate. The upper surfaces of the two fixing plates are fixed to the bottom ends of two support columns. The opposite sides of the two support columns are rotatably connected to the first and second baffles via rotating shafts. The opposite sides of the first and second baffles are fixedly connected by pins. The front surfaces of both the first and second baffles are coated with reflective paint, and a warning sign is fixed to the center of the front surfaces of both the first and second baffles.

[0004] Although the present invention has the advantages of warning passersby and preventing them from entering the tunnel construction section, the above technical solution has limitations in use. Due to the uneven construction environment, existing devices generally require the ground to be leveled before they can be fixed, which is not only time-consuming and labor-intensive but also reduces the effectiveness of the device. In addition, due to environmental requirements, existing devices are generally displayed vertically and cannot be adjusted according to the needs of use, which affects the effectiveness of the device.

[0005] Therefore, those skilled in the art have provided an easily adjustable warning device for tunnel construction to solve the problems mentioned in the background art. Utility Model Content

[0022] Please see Figure 1-4 An easily adjustable warning device for tunnel construction includes a warning sign 1, an adjustment mechanism 2 on the outer side of the warning sign 1, an adjustment frame 201, and a micro motor 212 on the outer side of the adjustment frame 201.

[0023] The output end of the micro motor 212 passes through the adjustment frame 201 and extends into the interior of the warning sign 1. The outer surface of the output end of the micro motor 212 is fixedly connected to the inner wall of the warning sign 1. The left side of the warning sign 1 is rotatably connected to the outer surface of the adjustment frame 201. Two movable frames 210 are provided below the adjustment frame 201. The upper surface of one of the movable frames 210 is fixedly connected to the controller body 205. The outer surface of the output end of the micro motor 212 is rotatably connected to the outer surface of the adjustment frame 201. An L-shaped plate 7 is fixedly connected to the outer surface of the micro motor 212. The left side of the L-shaped plate 7 is fixedly connected to the right side of the warning sign 1. The controller body 205 is electrically connected to the micro motor 212 through wires. The L-shaped plate 7 can be used to fix the micro motor 212, avoiding the problem of shaking during use, which would affect the effect of the device.

[0024] Each mobile frame 210 has a protective sleeve 213 fixedly connected to its upper surface. The outer surface of the controller body 205 is fixedly connected to a fixed shell 5. The bottom surface of the fixed shell 5 is fixedly connected to the upper surface of the mobile frame 210. The fixed shell 5 can protect the controller body 205 and prevent it from moving after long-term use, which could easily lead to the breakage of the wiring connection.

[0025] Each protective cylinder 213 has a support rod 202 slidably connected inside. The top of each support rod 202 is fixedly connected to the bottom surface of the adjustment frame 201. Each movable frame 210 has an anti-slip pad 6 underneath. The upper surface of each anti-slip pad 6 is fixedly connected to the bottom surface of the movable frame 210. The anti-slip pad 6 can protect the movable frame 210 and prevent it from tilting or shaking during use. The anti-slip pad 6 can also increase the friction between the device and the ground, thus protecting the device.

[0026] Each support rod 202 has a fastening bracket 203 threadedly connected to the inner wall of the protective cylinder 213. Each protective cylinder 213 has a bearing 204 fixedly connected to its outer surface. Each bearing 204 has a fixing bracket 211 fixedly connected to its outer surface. Each fixing bracket 211 has three support brackets 206 hinged to its inner wall. Each support bracket 206 has a movable bracket 207 hinged to its inner wall. Each movable bracket 207 has a base 208 fixedly connected to its bottom surface. Each support rod 202 has a fixing ring 4 fixedly connected to its outer surface. The top of each fixing ring 4 is fixedly connected to the bottom surface of the adjustment frame 201. The fixing rings 4 protect the support rod 202 and prevent it from shaking during use.

[0027] Each base 208 has two sets of threaded pins 209 threadedly connected to its inner wall. Each support rod 202 has two bolts 3 on its upper part. The outer surface of each bolt 3 is threadedly connected to the inner wall of the adjustment frame 201 and the inner wall of the support rod 202, respectively. The bolts 3 can be used to fix the support rod 202 to the adjustment frame 201 in a good way, so as to avoid the problem of the adjustment frame 201 shaking or tilting during use, which would affect the use effect and work efficiency of the device.

[0028] The working principle of this utility model is as follows: In use, first connect the support rod 202 and the controller body 205 to the power supply. When using the device, the worker moves it to the tunnel. Due to the varying ground conditions at the tunnel construction site, uneven surfaces are present. Based on the rotatable relationship between the bearing 204 and the fixed frame 211, and the movable relationship between the support frame 206 and the movable frame 207, the contact relationship between the base 208 and the uneven ground can be continuously adjusted according to the needs of the ground environment, ensuring the base 208 better conforms to the uneven ground. Then, the threaded pin 209 is used to fix the base 208 to the ground. Finally, the adjustment frame 201 is adjusted according to the width of the tunnel and the road. The height is adjusted by utilizing the sliding relationship between the support rod 202 and the fastening frame 203. When the support rod 202 and the protective cylinder 213 are adjusted to a suitable height, the fastening frame 203 is used to thread and fix the support rod 202 and the protective cylinder 213 together. Then, the rotation angle between the warning sign 1 and the adjustment frame 201 is adjusted according to the needs of use. The controller body 205 controls the rotation of the micro motor 212. Under the support of the adjustment frame 201, the micro motor 212 drives the warning sign 1 to rotate around the adjustment frame 201. As needed, the controller body 205 controls the rotation angle of the micro motor 212, thereby suspending the warning sign 1 and realizing the display of the warning sign 1 at different angles, thereby improving the use effect of the device.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
