Description

Technical Field

[0001] This utility model relates to the field of warning sign technology, specifically a warning sign for safety in construction projects. Background Technology

[0002] As we all know, safety is always paramount in the construction process. To effectively alert workers to potential dangers and prevent accidents, warning signs are widely used on various construction sites. Currently, most common construction warning signs use a structure where a support rod connects to a support plate. Specifically, fixing holes are pre-drilled in the support plate; the warning sign is secured by inserting ground nails into the ground and passing them through these holes.

[0003] However, these traditional warning signs have significant limitations. Firstly, because they are static, they struggle to stand out from the crowd of visual information in the complex environment of a construction site, failing to effectively attract the attention of workers. Especially when workers are distracted or the surrounding environment is highly disruptive, static warning signs are easily overlooked, thus reducing their warning effect and failing to fully fulfill their intended safety reminder function.

[0004] Therefore, in order to improve the warning effect and practicality of warning signs in construction projects, it is of great practical significance to develop a new type of warning sign device that can overcome the above-mentioned defects of existing technologies. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] In view of the shortcomings of the existing technology, this utility model provides a safety warning sign for construction projects, which solves the problems mentioned in the background technology.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a safety warning sign for construction projects, comprising a base plate and a warning plate. A support block is connected to the top of the base plate, and an installation groove is opened inside the support block. A sliding tube connected to the installation groove is connected to the top of the support block. A sliding cylinder with an opening facing downward and internal threads is inserted into the sliding tube. The outer wall of the sliding cylinder is multifaceted and matches the sliding tube. The sliding tube limits the rotation of the sliding cylinder. A fixing component for installing the warning plate is connected to the top of the sliding cylinder. A reciprocating rotating structure is rotatably connected in the installation groove. A threaded rod that is threadedly connected to the sliding cylinder is provided on the reciprocating rotating structure, and a motor installed on the support block is also connected thereto. The motor drives the reciprocating rotating structure, causing the threaded rod to rotate alternately in the forward and reverse directions of the sliding cylinder, thereby driving the sliding cylinder to slide up and down reciprocally in the sliding tube.

[0009] Furthermore, the reciprocating rotating structure includes a first rotating shaft and a second rotating shaft. A first helical gear and a second helical gear are mounted on the first rotating shaft. Two first rotating blocks are mounted on the first rotating shaft, which serve to limit the first rotating shaft on the support block. A second rotating block connected to the rotating end of the motor is mounted on the second rotating shaft. A toothed helical gear that meshes with both the first and second helical gears is also mounted on the second rotating shaft, which serves to limit the second rotating shaft on the support block.

[0010] Furthermore, the warning board consists of two panels, which are positioned one above the other, connected to each other, and perpendicular to each other.

[0011] Furthermore, the fixing component includes a mounting rod, the top of which is fixedly connected to a threaded post. The threaded post has a cross-shaped groove extending downwards from the top to the lower part of the mounting rod. A warning plate is inserted into the groove, and a threaded cap is threadedly connected to the threaded post for fixing the warning plate in the groove.

[0012] Furthermore, multiple rollers are installed on the bottom of the base plate.

[0013] Furthermore, the top of the base plate is fixedly connected with multiple evenly distributed external threaded pipes that are interconnected at the bottom of the base plate. Ground nails are inserted into the external threaded pipes and are used to insert into the underground base plate.

[0014] Furthermore, the externally threaded pipe is threaded with an internally threaded pipe for pulling out the ground nail.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a safety warning sign for construction projects, which has the following beneficial effects:

[0017] 1. Convenient Transfer and Positioning: The device is equipped with multiple evenly distributed casters at the bottom, allowing for easy relocation of the warning sign without the need for multiple people. A single person can easily push the device to the designated location, simplifying operation and significantly improving work efficiency. In contrast, traditional fixed-bracket-supported warning signs are typically bulky and require multiple people to move, wasting manpower and time.

[0018] 2. Flexible and reliable fixing method: The fixing method uses ground nails in combination with external and internal threaded tubes, which can not only firmly fix the device to the ground and adapt to different ground environments, but also easily pull out the ground nails by rotating the internal threaded tube during disassembly, which is convenient and quick.

[0019] 3. Dynamic warning effect: The reciprocating rotation structure of this device enables the warning board to produce a dynamic motion effect. The toothed helical gear alternately meshes with the first helical gear and the second helical gear, driving the first rotating shaft to rotate alternately under force, thereby causing the warning board to produce dynamic changes. Compared with traditional fixed warning signs, it is more likely to attract the attention of staff, improve the warning effect, and reduce the possibility of safety accidents.

[0020] 4. Compact structure, easy to install and maintain: The overall device has a compact structure, reasonable connections between components, relatively simple installation process, and easy disassembly and replacement of components during maintenance. 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] Please see Figure 1-5The present invention relates to a safety warning sign for construction projects, comprising a base plate 1 and a warning plate 8. The warning plate 8 consists of two plates, which are arranged vertically and connected to each other and perpendicular to each other. The bottom of the base plate 1 is equipped with a plurality of evenly spaced rollers 20, which facilitate the transfer of the device by pushing the device.

[0029] Multiple evenly distributed insertion holes are opened at the top edge of the base plate 1. Each insertion hole is provided with an external threaded tube 21, and the external threaded tube 21 is fixedly connected to the top of the base plate 1. A ground nail 22 is inserted through the insertion hole into the external threaded tube 21. The ground nail 22 is driven into the ground by a tool along the external threaded tube 21. The device is then fixed. An internal threaded tube 23 is threadedly connected to the external threaded tube 21. The internal threaded tube 23 is clamped by a tool and rotated on the external threaded tube 21, so that the internal threaded tube 23 pushes the ground nail 22 upward along the external threaded tube 21, so that tension is formed between the ground nail 22 and the external threaded tube 21, and the ground nail 22 is pulled out from the ground.

[0030] A support block 2 is connected to the top of the base plate 1. The support block 2 has an installation groove inside. A slide tube 3 connected to the installation groove is connected to the top of the support block 2. A slide cylinder 4 with an opening facing downward and internal threads is inserted into the slide tube 3. The outer wall of the slide cylinder 4 is multifaceted and matches the slide tube 3. The slide tube 3 limits the rotation of the slide cylinder 4. A fixing assembly for installing a warning plate 8 is connected to the top of the slide cylinder 4. The fixing assembly includes an installation rod 16. The installation rod 16 is vertically fixed to the top of the slide cylinder 4. A threaded post 18 is fixedly connected to the top of the installation rod 16. The threaded post 18 has a cross-shaped slide groove from the top downward and extends to the lower part of the installation rod 16. A warning plate 8 is inserted into the slide groove. A threaded cap 19 is threadedly connected to the threaded post 18 for fixing the warning plate 8 on the slide groove.

[0031] A reciprocating rotating structure 5 is rotatably connected in the mounting slot. The reciprocating rotating structure 5 includes a first rotating shaft 9 and a second rotating shaft 13. A first helical gear 10 and a second helical gear 11 are mounted on the first rotating shaft 9. Two first rotating blocks 12 are mounted on the first rotating shaft 9, which limit the first rotating shaft 9 on the support block 2. A second rotating block 15 connected to the rotating end of the motor 6 is mounted on the second rotating shaft 13, and a toothed helical gear 14 is also mounted on it. The second rotating block 15 limits the second rotating shaft 13 on the support block 2. The toothed helical gear 14 has teeth on one side. During the rotation of the toothed helical gear 14, the second rotating shaft 13 drives the toothed helical gear 14 to rotate. The toothed helical gear 14 has teeth on one side and will only mesh with one of the first helical gears 10 or the second helical gear 11 on the first rotating shaft 9. When the toothed helical gear 14 meshes with the first helical gear 10, power is transmitted to the first helical gear 10, which drives the first rotating shaft 9 to rotate, and the first rotating shaft 9 is subjected to a thrust in one direction. When the missing tooth portion of the helical gear 14 rotates to the corresponding position, the two disengage. Then, the missing tooth helical gear 14 meshes with the second helical gear 11, and the power is transmitted to the second helical gear 11 to drive the first rotating shaft 9. At this time, the first rotating shaft 9 is subjected to a thrust in the opposite direction. The reciprocating rotating structure 5 continues to operate, and the missing tooth helical gears 14 alternately mesh, causing the first rotating shaft 9 to be subjected to thrust in the opposite direction alternately.

[0032] The first rotating shaft 9 is connected to a threaded rod 7 that is threaded to the slide cylinder 4, and is also connected to a motor 6 that is mounted on the support block 2. The motor 6 is provided with a rain cover that is connected to the support block 2, and the rain cover serves to protect the motor 6.

[0033] In summary, the first step in using this type of safety warning sign for construction projects is to relocate and position the device.

[0034] First, push the device. Because the base plate 1 has multiple evenly distributed rollers 20 installed on its bottom, the device can move relatively easily on the ground. Push the device to the desired location, and after determining the specific placement position according to actual needs, stop pushing.

[0035] Step 2: Fix the device.

[0036] After determining the location of the device, begin the fixing process. Take the ground stake 22 and insert it into the threaded tube 21 at the top edge of the base plate 1. The ground stake 22 will penetrate the insertion hole below the threaded tube 21. Use a hammer or similar tool to gently tap the ground stake 22 along the threaded tube 21, gradually driving it into the ground. Continue in this manner, inserting multiple ground stakes 22 into their respective threaded tubes 21 and driving them into the ground until the device is firmly fixed to the ground and will not easily move.

[0037] Step 3: Installation of Warning Board 8

[0038] Next, install the warning plate 8. First, align the edge of the warning plate 8 with the cross-shaped groove of the threaded post 18 on the fixed component of the slide cylinder 4 at the top of the support block 2, and then carefully insert the warning plate 8 into the groove, ensuring that the warning plate 8 is inserted in place. After that, screw the threaded cap 19 onto the threaded post 18, use a wrench or other tools to hold the threaded cap 19, and turn it clockwise to tighten the threaded cap 19, so that the warning plate 8 is firmly fixed on the slide groove, ensuring that the warning plate 8 will not loosen or fall off during subsequent use.

[0039] Step 4: Start motor 6 and the rotating structure to run.

[0040] After completing the above installation and fixing steps, connect the power supply to the motor 6 connected to the device. After the motor 6 starts, its rotating end will drive the second rotating block 15 on the second rotating shaft 13 to rotate, thereby causing the second rotating shaft 13 to start rotating. The rotation of the second rotating shaft 13 will then drive the tooth-deficient helical gear 14 mounted on it to rotate. During the rotation of the tooth-deficient helical gear 14, because it has teeth on one side, it will only mesh with one of the first helical gear 10 or the second helical gear 11 on the first rotating shaft 9. When the tooth-deficient helical gear 14 meshes with the first helical gear 10, the power will be transmitted to the first helical gear 10, thereby driving the first rotating shaft 9 to rotate. At this time, the first rotating shaft 9 will be subjected to a thrust in one direction. As the tooth-deficient helical gear 14 continues to rotate, when the tooth-deficient part rotates to the position opposite to the first helical gear 10, the two disengage. When the teeth of the helical gear 14 with missing teeth rotate to correspond with and mesh with the second helical gear 11, power is transmitted to the second helical gear 11, driving the first rotating shaft 9 to rotate. At this time, the first rotating shaft 9 will be subjected to a thrust in the opposite direction to the previous one. This cycle continues, and the reciprocating rotating structure 5 continues to operate, with the helical gears 14 meshing alternately, causing the first rotating shaft 9 to be subjected to thrust in the opposite direction alternately.

[0041] Step 5: Adjust the height of the warning board 8.

[0042] During the rotation of the first rotating shaft 9, a threaded rod 7, which is threadedly connected to the slide cylinder 4, is connected to the end of the first rotating shaft 9. As the first rotating shaft 9 rotates, the threaded rod 7 also rotates. Because of the threaded connection between the threaded rod 7 and the slide cylinder 4, the rotation of the threaded rod 7 causes the slide cylinder 4 to move up and down within the slide tube 3. By utilizing the rotation of the first rotating shaft 9, the slide cylinder 4 rises or falls, thereby achieving the reciprocating up and down movement of the warning sign 8, making it easier to attract the attention of staff to observe the warning sign, thus serving as a warning.

[0043] Step 6: Disassembly and relocation of the device.

[0044] When the device needs to be moved, first use a tool to clamp the internally threaded tube 23, and rotate the internally threaded tube 23 counterclockwise on the externally threaded tube 21. This causes the internally threaded tube 23 to push the ground nail 22 upwards along the externally threaded tube 21. As the internally threaded tube 23 rotates, tension is created between the ground nail 22 and the externally threaded tube 21, thereby pulling the ground nail 22 out of the ground. After all the ground nails 22 have been pulled out, the device can be pushed again, and the rollers 20 can be used to move the device to a new position. Repeat the above steps for reinstallation and use.

[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
