Abstract
Description
Technical Field
[0001] This utility model relates to the field of highway survey warning technology, and in particular to a warning device for highway survey. Background Technology
[0002] Highway surveying is an important task involving the surveying and investigation of highways. It is usually carried out before highway construction, expansion, maintenance, or repair. Highway surveying aims to collect information on topography, geology, environment, and traffic to provide a scientific basis for highway design, construction, and operation. During highway surveying, warning devices are used to effectively identify potential danger zones, prevent vehicles from accidentally entering and damaging equipment or road facilities, and thus avoid highway damage caused by accidents.
[0003] Most existing warning devices are warning signs. When in use, the warning signs are placed in front of the survey area, and their reflective effect is used to improve their visibility at night or in low light conditions.
[0004] Although existing warning devices can serve their purpose, the height of existing warning signs is basically fixed. In some narrow roads or near obstacles (such as trees, billboards, buildings, etc.), the fixed-height warning signs will be obstructed, affecting their visibility and thus reducing the warning effect. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a warning device for highway surveying, which aims to improve the problem that the height of existing warning signs is basically fixed, and that the fixed-height warning signs will be blocked on some narrow roads or near obstacles (such as trees, billboards, buildings, etc.).
[0006] To achieve the above objectives, the present invention provides the following technical solution:
[0007] A warning device for highway surveying includes a base, a column fixedly connected to the upper part of the base, an adjusting column inside the column, an adjusting mechanism outside the column for adjusting the height of the warning sign, a mounting ring fixedly connected to the top of the adjusting mechanism, a frame fixedly connected to the outside of the mounting ring, a reflective warning plate installed inside the frame, and a replacement mechanism at the lower part of the frame for replacing the reflective warning plate.
[0008] The adjustment mechanism includes a fixed ring, which is fixedly connected to the outside of the column. A rotating rod is rotatably connected inside the fixed ring. A rotating plate is fixedly connected to the outside of the rotating rod. A handle is fixedly connected to the upper right side of the rotating plate. A pin is fixedly connected to the upper left side of the rotating plate. A first return spring is fixedly connected to the outside of the rotating plate. The top of the first return spring is fixedly connected to the outer left side of the rotating plate, and the bottom of the first return spring is fixedly connected to the outside of the fixed ring.
[0009] Furthermore, the replacement mechanism includes a U-shaped block, which is fixedly connected to the lower part of the frame. Fixed rods are fixedly connected to both sides inside the U-shaped block. The tops of the two fixed rods are fixedly connected to the lower sides of the frame. A movable plate is slidably connected to the outside of the two fixed rods. A second return spring is sleeved on the outside of the two fixed rods. A movable rod is fixedly connected to the lower part of the movable plate, and an insertion rod is fixedly connected to the upper part of the movable plate.
[0010] Furthermore, a third sliding hole is provided inside the column, and the adjusting column is slidably connected inside the third sliding hole.
[0011] Furthermore, a through hole is provided on the outer right side of the column, and the pin is slidably connected inside the through hole.
[0012] Furthermore, each of the adjusting columns has a slot on its outer right side, and the pin is inserted into the slot.
[0013] Furthermore, a first sliding hole is provided inside the U-shaped block, and the moving rod is slidably connected inside the first sliding hole. A second sliding hole is provided at the bottom of the frame, and the insert rod is slidably connected inside the second sliding hole.
[0014] Furthermore, the reflective warning plate has an insertion hole at its bottom, and the insertion rod is inserted into the insertion hole.
[0015] Furthermore, mounting holes are provided on all four sides of the inside of the base.
[0016] This utility model has the following beneficial effects:
[0017] 1. In this utility model, when adjusting the height of the reflective warning sign, first pull the handle to drive the rotating plate and rotating rod to rotate within the fixed ring. At the same time, the pin moves and stretches the first return spring. When the pin disengages from the slot, the adjustable column can be moved, thereby driving the mounting ring, frame and reflective warning sign to move. When the warning sign reaches the appropriate height, release the handle. The reaction force of the return spring causes the pin to re-insert into the slot, achieving locking. This design solves the problem of fixed height of traditional warning signs, avoids obstruction and improves the warning effect.
[0018] 2. In this utility model, when replacing the reflective warning plate, pulling the moving rod moves the moving plate and the insert rod downwards, compressing the second return spring. Once the insert rod disengages from the insertion hole, the reflective warning plate can be removed. After replacing the new warning plate, releasing the moving rod causes the return spring's reaction force to re-insert the insert rod into the insertion hole, completing the fixation. This design facilitates quick replacement of different reflective patterns, adapts to constantly changing environments, and enhances the flexibility of the warning device. Attached Figure Description

[0027] 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.
[0028] Reference Figure 1, Figure 3 and Figure 5 This utility model provides an embodiment of a warning device for highway surveying, comprising a base 1, a column 3 fixedly connected to the upper part of the base 1 for easy fixation of the column 3, an adjusting column 4 inside the column 3, and an adjusting mechanism outside the column 3 for adjusting the height of the warning sign, an installation ring 5 fixedly connected to the top of the adjusting mechanism, a frame 6 fixedly connected to the outside of the installation ring 5, a reflective warning plate 7 installed inside the frame 6 for easy installation of the reflective warning plate 7, a replacement mechanism at the bottom of the frame 6 for replacing the reflective warning plate 7, and mounting holes 2 on all four sides of the inside of the base 1 for easy fixation of the base 1;
[0029] The adjustment mechanism includes a fixed ring 8, which is fixedly connected to the outside of the column 3. A rotating rod 10 is rotatably connected inside the fixed ring 8. A rotating plate 11 is fixedly connected to the outside of the rotating rod 10. A handle 12 is fixedly connected to the upper right side of the rotating plate 11, and a pin 14 is fixedly connected to the upper left side of the rotating plate 11. A first return spring 13 is fixedly connected to the outside of the rotating plate 11. The top of the first return spring 13 is fixedly connected to the outer left side of the rotating plate 11, and the bottom of the first return spring 13 is fixedly connected to the outside of the fixed ring 8. A third sliding hole 25 is provided inside the column 3, and the adjustment column 4 is slidably connected inside the third sliding hole 25. The third sliding hole 25 facilitates the movement of the adjustment column 4. A through hole 9 is provided on the outer right side of the column 3, and the pin 14 is slidably connected inside the through hole 9. The through hole 9 facilitates the movement of the pin 14. A slot 15 is provided on the outer right side of the adjustment column 4, and the pin 14 is inserted into the slot 15, which improves the stability of the adjustment column 4.
[0030] Specifically, when adjusting the height of the reflective warning plate 7, firstly, by pulling the handle 12, the movement of the handle 12 will drive the rotating plate 11 fixed at the bottom, and at the same time, the internally connected rotating rod 10 will rotate inside the fixed ring 8. During the rotation of the rotating plate 11, the pin 14 fixedly connected on the outer left side will also move. During this process, the first return spring 13 is gradually stretched, deformed, and stores elastic potential energy. When the pin 14 is completely disengaged from the slot 15, the height of the adjusting column 4 can be freely adjusted. When the adjusting column 4 moves upward, it drives the mounting ring 5 fixed at the top to move together, and the mounting ring 5 is directly connected to... As the external frame 6 moves, the internally installed reflective warning plate 7 also rises accordingly. The warning plate can be adjusted to a suitable height according to actual needs to ensure that it is not obstructed by surrounding objects and to maximize its reflective warning effect. When the reflective warning plate 7 reaches the expected height, the handle 12 is released. At this time, the reaction force generated by the first return spring 13 after being stretched will cause the pin 14 to automatically return to its original position and quickly insert into the slot 15 to achieve automatic locking. This solves the limitation of the fixed height of traditional warning signs and greatly improves the flexibility of use, especially when the environment is changing or needs to be adjusted according to the actual situation.
[0031] Reference Figure 2 , Figure 4 and Figure 6 The replacement mechanism includes a U-shaped block 16, which is fixedly connected to the lower part of the frame 6. Two fixing rods 17 are fixedly connected to both sides of the inside of the U-shaped block 16. The tops of the two fixing rods 17 are fixedly connected to the lower sides of the frame 6. A movable plate 18 is slidably connected to the outside of the two fixing rods 17. A second return spring 21 is sleeved on the outside of each of the two fixing rods 17. A movable rod 19 is fixedly connected to the lower part of the movable plate 18, and an insertion rod 20 is fixedly connected to the upper part of the movable plate 18. A first sliding hole 23 is opened inside the U-shaped block 16, and the movable rod 19 is slidably connected inside the first sliding hole 23. The first sliding hole 23 facilitates the movement of the movable rod 19. A second sliding hole 24 is opened at the bottom of the frame 6, and the insertion rod 20 is slidably connected inside the second sliding hole 24. The second sliding hole 24 facilitates the movement of the insertion rod 20. An insertion hole 22 is opened at the bottom of the reflective warning plate 7, and the insertion rod 20 is inserted into the insertion hole 22, improving the stability of the reflective warning plate 7 installation.
[0032] Specifically, when it is necessary to replace different reflective warning plates 7, firstly, pull the moving rod 19. The downward movement of the moving rod 19 drives the top-fixed moving plate 18 to slide outside the two fixed rods 17. During the movement of the moving plate 18, the plug rod 20 connected to it will also move downward synchronously. At this time, the movement of the moving plate 18 will also exert a squeezing effect on the second return spring 21 sleeved outside the two fixed rods 17, causing the second return spring 21 to deform under force and accumulate elastic energy. When the plug rod 20 is completely disengaged from the plug hole 22, the connection between the reflective warning plate 7 and the frame 6 is released, and the reflective warning plate 7 can be easily removed from the inside of the frame 6. After removing the old warning plate, the user can select and install different reflective warning plates 7 according to the current working environment or site requirements. During installation, only... Align the new reflective warning plate 7 with the inside of the frame 6 and snap it into the fixed position of the frame 6. After placing the new warning plate, release the moving rod 19. At this time, the two second return springs 21, after being deformed by the previous force, will release their stored elastic energy and generate a reaction force, pushing the insertion rod 20 to automatically return to its original position. Under the action of the second return springs 21, the insertion rod 20 is inserted into the inside of the insertion hole 22, ensuring that the warning plate is locked back on the frame 6. This allows for quick adjustment of the warning content according to the actual situation, thereby better adapting to different working environments or emergency situations. For example, in different construction sites, traffic control areas, or other occasions where warnings are required, operators can flexibly change reflective patterns or information prompts to ensure timely and accurate transmission of warning information, greatly improving the practicality and flexibility of the warning device.
[0033] Working principle: When the height of the reflective warning plate 7 needs to be adjusted, firstly, by pulling the handle 12, the handle 12 moves and causes the rotating rod 10 fixed inside the rotating plate 11 at the bottom to rotate inside the fixed ring 8. When the rotating plate 11 rotates, it moves the pin 14 fixed on the left side of the outside and stretches the first return spring 13, causing the first return spring 13 to deform under force. Then, when the pin 14 disengages from the inside of the slot 15, the adjusting column 4 can be moved. The adjusting column 4 moves and causes the mounting ring 5 fixed at the top to move. The mounting ring 5 moves and causes the frame 6 fixed on the outside to move. The frame 6 moves and causes the reflective warning plate 7 installed inside to move. When the reflective warning plate 7 moves to the appropriate height, the handle 12 is released. Under the reaction force of the first return spring 13, the pin 14 is inserted into the inside of the slot 15. This makes it easy to adjust the height of the reflective warning plate 7, solves the problem that the height of traditional warning signs is basically fixed, avoids the warning sign being blocked, and thus improves the warning effect of the warning sign.
[0034] When it is necessary to replace different reflective warning plates 7, firstly, pull the moving rod 19. The moving rod 19 moves the top-fixed moving plate 18 downward outside the two fixed rods 17. When the moving plate 18 moves, it moves the upper-fixed insertion rod 20 synchronously. When the moving plate 18 moves with the insertion rod 20, it squeezes the second return spring 21 sleeved outside the two fixed rods 17, causing the two second return springs 21 to deform under force. Then, when the insertion rod 20 is disengaged from the inside of the insertion hole 22, the reflective warning plate 7 can be taken out from the inside of the frame 6 for replacement. When installing different reflective warning plates 7, the different reflective warning plates 7 are stuck inside the frame 6. Then, the moving rod 19 is released, and under the reaction force of the two second return springs 21, the insertion rod 20 is inserted into the inside of the insertion hole 22. This makes it easy to replace different reflective warning plates 7, and different reflective patterns or information content can be quickly adjusted according to the needs of the site, adapting to constantly changing environments or working conditions, and improving the flexibility of the warning device.
[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
