Description

Technical Field

[0001] This utility model relates to the field of early warning technology for building construction, and in particular to an early warning device for building construction safety management. Background Technology

[0002] Currently, the safety warning signs used on construction sites are basically just a metal frame supporting a sign with words like "No Entry" or "Caution: Falling Objects." However, conditions on construction sites change rapidly. Today, a "No Entry" sign needs to be put up for digging a trench, and tomorrow a "Caution: Falling Objects" sign needs to be changed for scaffolding. The safety officer in charge of safety on the construction site has to carry several signs back and forth every day, not only getting tired and with a sore back, but sometimes no one is watching when changing the signs, and workers unknowingly enter the danger zone.

[0003] Existing technologies generally employ fixed warning signs or simple flip-up signage devices to provide safety warnings for construction areas through text and images. With fixed warning signs, the signs need to be replaced when the construction content changes, requiring manual removal of multiple bolts using tools. With flip-up warning signs, only one adjacent warning side can be switched at a time, and if the required warning sign is obscured, multiple rotations are required to adjust to the desired warning content, resulting in cumbersome operation. To solve the above problems, this application proposes a construction safety management early warning device. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a construction safety management early warning device. This device uses a rotating mechanism to rotate multiple warning signs, directing the desired signs to the front for warning purposes, thus meeting diverse usage needs and offering simple operation. Furthermore, a limiting mechanism allows the device to be opened or moved closer together, making it highly practical.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A construction safety management early warning device includes a rotating column, which is a multi-faceted column. Each face of the rotating column is fixedly connected to a construction early warning sign and multiple warning lights. A U-shaped plate is provided below the rotating column. A rotating mechanism is provided between the rotating column and the U-shaped plate. Four rotating rods are rotatably connected to the outer wall of the U-shaped plate. A gear is fixedly connected to the outer wall of each rotating rod. Two gears on the same side mesh with each other. A swing leg is fixedly connected to the end of each rotating rod. Two swing legs on the front side are fixedly connected to arc plates. The two arc plates pass through the corresponding swing legs and are slidably connected to them. The two swing legs on the front side and the two swing legs on the rear side are jointly fixedly connected to a reinforcing column. Each arc plate is provided with a limiting mechanism.

[0007] Preferably, the rotating mechanism includes two rotating rods fixedly connected to the outer wall of the rotating column. Both rotating rods are rotatably connected to the U-shaped plate. A worm gear is fixedly connected to the outer wall of the rotating rod on the right side. The worm gear meshes with a worm. A handle is fixedly connected to the front end of the worm. Two mounting blocks are fixedly connected to the inner wall of the U-shaped plate. The worm passes through the two mounting blocks and is rotatably connected to them.

[0008] Preferably, the limiting mechanism includes a swing leg and a T-shaped rod slidably connected thereto. A spring is sleeved on the outer wall of the T-shaped rod, and the two ends of the spring are fixedly connected to the swing leg and the T-shaped rod, respectively. Multiple insertion holes are provided on the arc plate, and the T-shaped rod is inserted into the corresponding insertion holes.

[0009] Preferably, the outer wall of the handle is covered with a protective sleeve, and the protective sleeve is made of rubber.

[0010] Preferably, the swing leg has a through opening, and the arc plate is provided through the through opening.

[0011] Preferably, the plurality of the sockets are distributed at equal intervals.

[0012] Compared with the prior art, the advantages of this utility model are as follows:

[0013] 1. This patent integrates multiple warning signs through a multi-faceted column structure, and uses a worm gear transmission mechanism to achieve precise angle positioning. Any warning face can be quickly switched with a single rotation, solving the problem of low switching efficiency in traditional devices.

[0014] 2. Integrates multiple sets of flashing warning lights to improve visibility through dynamic red light warnings.

[0015] 3. The innovative gear linkage mechanism enables the four legs to unfold synchronously. Two sets of meshing gears ensure the symmetrical movement of the swing legs. Compared with independently adjustable legs, the unfolding time is reduced and the support stability is improved.

[0016] 4. The arc plate and T-shaped rod limiting mechanism, together with the spring, reduce the volume of the outriggers to half of their unfolded state after folding, and the stowed state has a mechanical self-locking function, completely solving the structural interference problem during transportation.

[0017] In summary, the rotating mechanism allows multiple warning signs to be rotated so that the desired warning sign faces forward for effective warning, meeting various usage needs and offering simple operation; the limiting mechanism allows the device to be opened or closed for transport, making it highly practical.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figures 1-2 A construction safety management early warning device includes a rotating column 1, which is a multi-faceted column. Each face of the rotating column 1 is fixedly connected to a construction early warning sign 2. The construction early warning signs 2 are warning signs for various purposes, such as prohibiting passage, prohibiting unauthorized personnel from entering, construction site safety warning, and emergency exit. Each sign has a different function. By facing the construction early warning signs 2 with different warning messages, a warning effect is achieved. Each face of the rotating column 1 is fixedly connected to multiple warning lights 3. The warning lights 3 are connected to a built-in lithium battery and are controlled by a control module to achieve a red light flashing mode. They can flash red light at night or in low light conditions to serve as a warning.

[0023] A U-shaped plate 4 is provided below the rotating column 1. A rotating mechanism is provided between the rotating column 1 and the U-shaped plate 4. The rotating mechanism includes two rotating rods 5 fixedly connected to the outer wall of the rotating column 1. Both rotating rods 5 are rotatably connected to the U-shaped plate 4. A worm gear 6 is fixedly connected to the outer wall of the rotating rod 5 on the right side. The worm gear 6 meshes with a worm 7. A handle 8 is fixedly connected to the front end of the worm 7. A protective sleeve is provided on the outer wall of the handle 8. The protective sleeve is made of rubber to increase comfort. Two mounting blocks are fixedly connected to the inner wall of the U-shaped plate 4. The worm 7 passes through the two mounting blocks and is rotatably connected to them. The self-locking property of the worm gear and worm 7 can make the rotating column 1 rotate to different faces and lock them, so that different construction warning signs 2 face the front.

[0024] Four rotating rods 9 are rotatably connected to the outer wall of the U-shaped plate 4. Each rotating rod 9 is fixedly connected to a gear 10 on its outer wall. Two gears 10 on the same side mesh with each other. Each rotating rod 9 is fixedly connected to a swing leg 11 at its end. The gears 10 can make the swing legs 11 on both sides move relative to each other or away from each other, so as to realize the synchronous movement of the two pairs of swing legs 11 away from each other and close together, thus providing stable support for the device.

[0025] Both front swing legs 11 are fixedly connected to arc plates 12. The two arc plates 12 pass through the corresponding swing legs 11 and are slidably connected to them. The swing legs 11 have through openings, and the arc plates 12 pass through the through openings. The two front swing legs 11 and the two rear swing legs 11 are fixedly connected to reinforcing columns 13 to ensure the stability of the device. Each arc plate 12 is provided with a limiting mechanism, which includes a T-shaped rod 14 that is slidably connected to the swing leg 11. A spring 15 is sleeved on the outer wall of the T-shaped rod 14. The two ends of the spring 15 are fixedly connected to the swing leg 11 and the T-shaped rod 14, respectively. Multiple insertion holes 16 are provided on the arc plate 12. The multiple insertion holes 16 are evenly distributed. The T-shaped rod 14 is inserted into the corresponding insertion hole 16. By inserting the T-shaped rod 14 into different insertion holes 16, the distance between the two sets of swing legs 11 can be adjusted. They can be far apart for support or close together for easy handling and carrying.

[0026] In this invention, the worker holds the handle 8 and rotates it to drive the worm gear 7, worm wheel 6, right-side rotating rod 5, rotating column 1, and left-side rotating rod 5 to rotate. The rotation of the rotating column 1 drives multiple construction warning signs 2 to rotate, causing different signs 2 to face forward. Different signs 2 can be positioned facing forward according to the construction content, serving as a safety warning and preventing people from accidentally entering the construction site. When it is necessary to swing the front and rear swing legs 11 away from each other, the worker holds the two T-shaped rods 14 and moves them relative to each other. During this process, the spring 15 stretches until both T-shaped rods 14 are disengaged from the insertion hole 16, thus moving the front and rear swing legs 11 away from each other. During this process, the arc plate 12 slides within the opening. Move the device until the distance between the front and rear swing legs 11 is appropriate. At this point, release the T-shaped rod 14 and insert it into the corresponding socket 16 under the action of the spring 15. This limits the position of the four swing legs 11 and allows them to work together to support the device stably. The two pairs of gears 10 can also make the swing legs 11 on both sides swing at the same angle, making the device more stable. When the device needs to be moved, the operator holds the two T-shaped rods 14 and moves them relative to each other. During this process, the spring 15 is stretched and the T-shaped rods 14 are disengaged from the socket 16, which brings the front and rear swing legs 11 together. Inserting the T-shaped rods 14 into the corresponding socket 16 completes the closing and limiting of the four swing legs 11, which facilitates the movement and handling of the device.

[0027] This invention solves the problems of existing fixed warning signs, which require manual removal of multiple bolts to replace the signs when the construction content changes, and flip-up warning signs, which can only switch one adjacent warning face at a time. If the required warning sign is blocked, multiple rotation operations are required to adjust it to the desired warning content, which is cumbersome.
