Description

Technical Field

[0001] This utility model relates to the field of warning sign technology, specifically to a municipal engineering construction warning sign. Background Technology

[0002] Chinese patent CN221822790U discloses a warning sign for municipal engineering construction, including a warning frame. A support assembly is slidably installed within the warning frame. When needed, pulling the support base plate in the support assembly causes two sets of support columns to extend from the warning frame, allowing two sets of limiting plates to abut against the bottom of the warning frame. First threaded rods at the bottom of the two limiting plates extend from the second through holes at the bottom of the warning frame. Nuts are used to lock the first threaded rods to the bottom of the warning frame, thus placing the device in a supported state. After use, the nuts can be unscrewed from the first threaded rods, allowing the support base plate to fit against the warning frame. Two sets of second threaded rods at the bottom of the warning frame pass through the two limiting holes on the support base plate. The two sets of nuts unscrewed from the first threaded rods are then fixed to the second threaded rods, limiting and fixing the support base plate and the warning frame, thus enabling the device to be carried. This allows for both supported and retractable carrying states. However, there are still shortcomings that can be improved.

[0003] 1. In this utility model, two support columns are used to support the warning frame. However, it should be noted that the height of the support columns is constant. In reality, different construction projects have different environments, which leads to different optimal heights for pedestrians to see the warning signs. If the height cannot be adjusted, pedestrians may not be able to see the warning signs in time, so improvements are needed.

[0004] 2. In this utility model, a warning sign is used as a component to remind people around to stay away in time. However, during the construction of municipal engineering projects, a lot of dust will inevitably be generated. This dust will accumulate on the surface of the warning sign. If there are no maintenance personnel to clean it, it may obscure the warning sign, thereby affecting pedestrians' reading.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0013] As an improvement, a baffle is fixedly connected to the lower part of the inner wall of the protective sleeve, and a rotating hole is opened in the middle of the top of the baffle. A rotating shaft is rotatably connected in the rotating hole, and a threaded column is fixedly connected to the top of the rotating shaft. The threaded column is threadedly connected to the lifting column.

[0014] As an improvement, the bottom end of the rotating shaft passes through the bottom end of the rotating hole and is fixedly connected to a servo motor, which is fixedly connected to the bottom wall of the protective sleeve by a motor mount.

[0015] As an improvement, the cleaning device includes a connecting plate located on the lower front side of the cabinet door, and a brush plate is provided at the rear end of the connecting plate. The brush plate can clean the surface of the cabinet door as it moves up and down.

[0016] As an improvement, a receiving plate is fixedly connected to both sides of the connecting plate, and a connecting plate is fixedly connected to the upper part of the rear end of the receiving plate on both sides.

[0017] As an improvement, a multi-stage hydraulic rod is fixedly connected to the bottom end of each of the two connecting plates, and a fixed seat is fixedly connected to the bottom end of each of the multi-stage hydraulic rods. The adjacent sides of the fixed seats on both sides are fixedly connected to the warning box. A telescopic limiting rod is fixedly connected to the rear part of the bottom end of each of the two connecting plates, and a connecting frame is fixedly connected to the bottom end of each telescopic limiting rod. The adjacent sides of the connecting frames on both sides are fixedly connected to the warning box.

[0018] The advantages of this utility model compared with the prior art are as follows:

[0019] 1. In this utility model, a lifting device is provided, which indirectly drives the threaded column to rotate via a servo motor, thereby causing the threaded column to rotate the warning box. This allows users to adjust the height of the warning box in a timely manner according to the site conditions, ensuring that pedestrians can see the warning signs inside the box promptly, thus protecting their health and safety.

[0020] 2. In this utility model, a cleaning device is set in front of the cabinet door.

[0033] The present invention will now be described in further detail with reference to the accompanying drawings.

[0034] The working principle of this utility model is as follows: Figures 1-3 As shown, a construction warning sign for municipal engineering includes: a base 1; a warning box 3 is first set on the top of the base 1; a warning board 4 is fixedly connected to the middle of the bottom wall of the warning box 3; a warning slogan is affixed to the front of the warning board 4 to inform pedestrians that construction is underway; and several horizontally arranged lights 5 are set in front of the warning board 4, with the lights 5 fixedly connected to the front of the bottom wall of the warning box 3. In this way, the lights 5 illuminate the warning board 4, allowing pedestrians to see the warning slogan even in the dark.

[0035] Meanwhile, a cabinet door 6 is rotatably connected to the top of the front end of the warning box 3, and the middle of the cabinet door 6 has a glass window, so that pedestrians can see the warning board 4 inside through the glass window. In addition, in order to fix the cabinet door 6 after it is closed, quick-release female buckles 8 are fixedly connected to both sides of the bottom front of the warning box 3, and quick-release male buckles 7 are fixedly connected to both sides of the bottom of the cabinet door 6. It should be noted that the quick-release male buckle 7 is inserted into the quick-release female buckle 8, and the quick-release male buckle 7 is fixed by the limiting device of the quick-release female buckle 8, so that the cabinet door 6 is fixed and cannot be rotated.

[0036] In addition, a cleaning device 10 is installed in front of the warning box 3 to work with the cabinet door 6. The cleaning device 10 can clean the dust on the surface of the cabinet door 6.

[0037] In order to raise and lower the warning box 3 to a suitable height so that pedestrians can read the warning signs in time, a protective sleeve 2 is fixedly connected to the middle of the top of the base 1, and a lifting device 9 is installed inside the protective sleeve 2 to work with the warning box 3.

[0038] The above-mentioned structures together constitute the general appearance structure of a municipal engineering construction warning sign according to this utility model.

[0039] like Figure 5 and 6As shown, in order to further explain the specific working principle of the municipal engineering construction warning sign of this utility model, the cleaning device 10 includes a connecting plate 1001 located on the lower side in front of the cabinet door 6. Then, a fixed seat 1006 is fixedly connected to the lower part of both sides of the warning box 3. Then, a multi-stage hydraulic rod 1005 is fixedly connected to the top of both fixed seats 1006. At the same time, a connecting plate 1004 is fixedly connected to the top of the multi-stage hydraulic rod 1005. In this way, the multi-stage hydraulic rod 1005 can push the connecting plate 1004 to rise and fall.

[0040] Meanwhile, telescopic limit rods 1007 are fixedly connected to the rear of the bottom of the two side connecting plates 1004, and connecting frames 1008 are fixedly connected to the bottom of the two side telescopic limit rods 1007. The connecting frames 1008 are fixedly connected to the warning box 3. In this way, when the two side multi-stage hydraulic rods 1005 push the connecting plates 1004 to rise and fall, the telescopic limit rods 1007 can extend and retract accordingly, which can limit the connecting plates 1004 and prevent overshoot. At the same time, it can make the rising and falling of the connecting plates 1004 more stable.

[0041] In addition, a receiving plate 1003 is fixedly connected to the front end of both connecting plates 1004, and the adjacent sides of the receiving plates 1003 on both sides are fixedly connected to the connecting plate 1001. When the connecting plate 1004 moves up and down, the receiving plate 1003 fixedly connected to the connecting plate 1004 will drive the connecting plate 1001 to move up and down.

[0042] Finally, a brush plate 1002 is fixedly connected to the rear end of the connecting plate 1001. When the connecting plate 1001 is raised or lowered, the brush plate 1002 fixedly connected to the connecting plate 1001 can clean the dust on the surface of the cabinet door 6.

[0043] It should be noted that the brushes on the brush plate 1002 are soft and have a certain degree of deformation ability. Therefore, during the process of the brush plate 1002 rising and falling along with the connecting plate 1001, its brushes are in contact with the surface of the cabinet door 6, and the brushes can continuously clean the surface of the cabinet door 6.

[0044] The technical effect achieved by the technical solution composed of the above-mentioned technical features is as follows: the multi-stage hydraulic rods 1005 on both sides first push the corresponding connecting plates 1004 to rise and fall. During the rising and falling process, the connecting plates 1004 on both sides will drive the receiving plates 1003 to move together. In this way, the connecting plate 1001 fixedly connected to the receiving plate 1003 will drive the brush plate 1002 to move together. Since the brush plate 1002 and the cabinet door 6 are used in conjunction, the cabinet door 6 can be cleaned during the rising and falling process of the brush plate 1002. It should be noted that when the cleaning device 10 stops running, the connecting plate 1001 is located below the cabinet door 6, so the rotation of the cabinet door 6 is not affected.

[0045] like Figure 4 As shown, in order to further explain the specific working principle of the municipal engineering construction warning sign of this utility model, the above-mentioned lifting device 9 includes a baffle 904 fixedly connected to the lower part of the inner wall of the protective sleeve 2, and a rotating hole 905 is opened in the middle of the top of the baffle 904. At the same time, a servo motor 908 is provided below the baffle 904. The servo motor 908 is fixedly connected to the bottom wall of the protective sleeve 2 by a motor base 909. Then, a rotating shaft 906 is fixedly connected to the top of the servo motor 908, and the rotating shaft 906 is rotatably connected in the rotating hole 905.

[0046] Next, a threaded post 907 is fixedly connected to the top of the rotating shaft 906. It should be noted that the fixed connection between the threaded post 907 and the rotating shaft 906 is a key connection. The rotating shaft 906 is driven to rotate by the servo motor 908, and the rotating shaft 906 can drive the threaded post 907 to rotate.

[0047] Meanwhile, a lifting column 901 is threadedly connected to the threaded column 907, and the top of the lifting column 901 is fixedly connected to the warning box 3. In addition, the lifting column 901 is also slidably connected inside the protective sleeve 2. Then, limit blocks 903 are fixedly connected to the lower parts of both sides of the lifting column 901, and sliding grooves 902 are opened on the upper parts of the two side walls of the protective sleeve 2. The limit blocks 903 are slidably connected in the corresponding sliding grooves 902, thus ensuring the stability of the lifting column 901 during the lifting process.

[0048] The technical effect achieved by the technical solution composed of the above technical features is as follows: In specific use, the servo motor 908 drives the rotating shaft 906 to rotate. During the rotation of the rotating shaft 906, the threaded column 907 will rotate together. Since the threaded column 907 and the lifting column 901 are threaded together, the lifting column 901 will rise and fall when the threaded column 907 rotates. During this process, the limit blocks 903 on both sides will slide in the sliding groove 902. Finally, the lifting column 901 will drive the warning box 3 to rise and fall.

[0049] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.

[0050] In addition, all electrical components mentioned in this article are connected to an external main controller and 220V AC mains power. The main controller can be a conventional known device such as a computer for control. The multi-stage hydraulic rod mentioned in the article is connected to an external oil circuit. The detailed description of known functions and known components is omitted in the specific implementation of this disclosure. In order to ensure the compatibility of the equipment, the operating methods adopted are consistent with the parameters of commercially available instruments.
