Description

Technical Field

[0001] This invention relates to the field of building construction, specifically a safety warning device for building construction. Background Technology

[0002] During the construction of buildings and civil engineering projects, there are often many safety hazards at the construction site, such as falling objects from heights, mechanical injuries, and foundation pit collapses. Therefore, it is crucial to set up safety warning devices to alert and isolate passing personnel and vehicles.

[0003] Traditional construction safety warning equipment has a fixed overall structure, is large in size, and cannot be folded, making it extremely inconvenient to move between multiple construction sites. This not only increases the difficulty and labor intensity of manual transportation but also reduces the utilization efficiency of the equipment. Secondly, because the warning components are exposed for a long time without an effective storage and protection structure, they are easily damaged by bumps and squeezes during transportation and storage, causing damage to key components such as displays and warning boards. At the same time, in the harsh natural environment of the construction site, long-term exposure also accelerates the aging and failure of the equipment, resulting in high maintenance costs and short service life. Summary of the Invention

[0004] The purpose of this invention is to provide a safety warning device for building construction, in order to solve the problems mentioned in the background art.

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

[0006] A safety warning device for building construction includes a protective box and an adjustable warning mechanism. The adjustable warning mechanism is slidably disposed at the center of the protective box for providing safety warnings at the building construction site. The mechanism includes a display frame, the four corners of which are slidably connected to the top plate of the protective box via first guide components. A display screen and a warning regulation display board are respectively provided at both ends of the display frame. The display screen is detachably installed inside the display frame, and the four corners of the warning regulation display board are slidably inserted into the display frame via second guide components. An internally threaded pipe is also fixedly installed at the center of the display frame. A rotating rod is rotatably connected to the bottom plate of the protective box at its bottom, and a threaded portion is provided at the top of the rotating rod, which is threadedly connected to the internally threaded pipe. A drive gear is also installed on the rotating rod. A synchronous protection mechanism is disposed on both side walls of the protective box for providing safety protection at the building construction site. This mechanism includes a sealing plate. The sealing plate is placed on the side walls at both ends of the protective box to seal the openings in the side walls of the protective box; the connecting frame is connected to the sealing plate at its outer end; the rack plate is placed on the inner wall of the connecting frame and meshes with the drive gear. The spatial action coupling of lifting warning and lateral isolation is achieved through a single rotational power source of the rotating rod. The threaded part of the rotating rod rotates, and the threaded part drives the internal threaded tube and the display frame to move upward to the outside of the protective box under the guidance of the first guide component. The display and warning display board on the display frame are used to provide safety warnings to the surrounding construction site. At the same time, the same rotating rod is used to split the power, and the rotating rod synchronously drives the drive gear to rotate. The drive gear drives the meshing rack plate and the connecting frame to move the sealing plate outward to unfold and protect the construction site. This achieves improved unfolding efficiency with a single power input while ensuring the synchronization of safety warning and physical protection actions.

[0007] Preferably, the protective box is equipped with casters around its bottom, and a reflective groove is provided on the outer side wall of the front of the protective box. An advertising board is installed in the reflective groove to enhance the visual cues to the outside world when the equipment is moving or under warning conditions.

[0008] Preferably, the first guide component includes an arc-shaped guide protrusion and an arc-shaped guide groove. The arc-shaped guide protrusion is fixedly disposed at the four corners of the outer wall of the display frame, and the arc-shaped guide groove is correspondingly disposed on the top plate of the protective box. The arc-shaped guide protrusion is inserted into the arc-shaped guide groove and is slidably connected in the vertical direction.

[0009] Preferably, the second guide component includes a T-shaped guide protrusion and a first T-shaped guide groove. The T-shaped guide protrusion is fixedly disposed on the four corner edges of the warning regulation display board, and the first T-shaped guide groove is correspondingly opened on the inner wall of the display frame. The T-shaped guide protrusion is inserted into the first T-shaped guide groove to realize the detachable connection between the warning regulation display board and the display frame.

[0010] Preferably, a protective cover is provided at the bottom of the rotating rod, the protective cover is fixedly installed on the bottom inner wall of the protective box, and a rotation drive assembly for driving the rotating rod to rotate is also installed on the protective cover.

[0011] Preferably, the rotation drive assembly includes a rotation motor, a first bevel gear, and a second bevel gear. The rotation motor is fixedly mounted on the protective cover, the first bevel gear is mounted on the output shaft of the rotation motor, and the second bevel gear is fixedly sleeved on the bottom of the rotating rod, and the second bevel gear is meshed with the first bevel gear.

[0012] Preferably, the module of the drive gear matches the module of the rack plate to ensure that the drive gear can accurately and smoothly drive the rack plates on both sides to perform synchronous linear reciprocating motion when rotating.

[0013] Preferably, the sealing plate facing the inside of the protective box is connected to the connecting frame via a third guide assembly; the third guide assembly includes a T-shaped guide frame and a second T-shaped guide groove; the T-shaped guide frame is fixedly installed at the outer end of the connecting frame, and the second T-shaped guide groove is opened on the inner side wall of the sealing plate, and the T-shaped guide frame and the second T-shaped guide groove cooperate to realize the sliding guidance when the sealing plate moves.

[0014] Preferably, the synchronous protection mechanism further includes a waterproof plate and a fixing component. The waterproof plate is disposed on the top of the rack plate and is fixedly connected to the inside of the connecting frame. A drainage groove is provided on the top inclined surface of the waterproof plate. A baffle is provided at the end of the drainage groove on the side away from the sealing plate, and a drainage recess is provided at the end of the drainage groove on the side close to the sealing plate. The fixing component includes a fixing seat and mounting holes. The fixing seat is fixed to the bottom of the protection box, and the mounting holes are opened at both ends of the bottom of the fixing seat for use with anchor bolts to fix the equipment.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] This invention uses a single rotating rod as a power source, with its threaded top driving the display frame to rise and fall vertically. Simultaneously, a drive gear on the rod moves the rack and pinion plate and the sealing plate horizontally. This design achieves spatial coupling between the upward display of warning components and the lateral unfolding of protective components, significantly improving the efficiency and synchronization of the equipment's unfolding and retraction, and solving the problems of traditional equipment's limited functionality and cumbersome operation.

[0017] When not in operation or during relocation, the display frame can be completely stored inside the protective box, and the sealing plate automatically closes, forming a closed protection for delicate and vulnerable components such as the display screen and warning notice display board. This effectively avoids damage caused by bumps, squeezing, or severe weather, and extends the service life of the equipment. Attached Figure Description

[0048] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other.

[0049] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the various embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been presented in the various embodiments of the present invention to facilitate a better understanding of this application. However, the technical solutions claimed in this application can be implemented even without these technical details and various changes and modifications based on the following embodiments.

[0050] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0051] See Figures 1-12 The present invention provides a safety warning device for building construction, including a protective box 1, an adjustable warning mechanism 2, and a synchronous protection mechanism 3. The protective box 1 serves as the supporting base of the device, and is equipped with casters 11 around its bottom for easy movement and relocation within the construction site. A reflective groove 12 is provided on the outer side wall of the front of the protective box 1, and an advertising board 13 is installed in the groove, which can provide passive reflective warning to the outside world when the device is in motion or stored.

[0052] See Figure 1 In one embodiment of the present invention, the adjustable warning mechanism 2 is slidably disposed at the center of the protective box 1 for displaying the main safety information. The adjustable warning mechanism 2 includes a display frame 21. The four corners of the display frame 21 are slidably connected to the top plate of the protective box 1 through a first guide component 22. The first guide component 22 is composed of an arc-shaped guide protrusion 221 and an arc-shaped guide groove 222. The arc-shaped guide protrusion 221 is fixed to the four corners of the outer wall of the display frame 21 and is inserted into the arc-shaped guide groove 222 opened on the top plate of the protective box 1 to achieve stable vertical lifting and lowering guidance, ensuring that the entire display frame 21 can be moved up and down smoothly for directional adjustment.

[0053] The display frame 21 is equipped with a display 24 and a warning notice display board 210 at its two ends. The display 24 is detachably installed inside the display frame 21 for dynamically displaying warning information. The four corners of the warning notice display board 210 are slidably connected to the display frame 21 through a second guide component 23. The second guide component 23 is composed of a T-shaped guide protrusion 231 and a first T-shaped guide groove 232. The T-shaped guide protrusion 231 is fixed at the four corners of the display board 210 and can be easily inserted into the first T-shaped guide groove 232 on the inner wall of the display frame 21, which facilitates quick disassembly and replacement, thereby making it easy to change different warning slogans or warning content to suit different building construction sites.

[0054] A threaded tube 25 is fixedly connected to the center of the display frame 21, and a rotating rod 26 is set at the bottom. The bottom of the rotating rod 26 is rotatably connected to the bottom plate of the protective box 1 through a bearing, and the top is provided with a threaded part 261, which is threadedly connected to the threaded tube 25. A protective cover 27 is provided at the bottom of the rotating rod 26 and fixed to the bottom plate of the protective box 1. A rotation drive assembly 28 is installed on the protective cover 27. The rotation drive assembly 28 includes a rotation motor 281, a first bevel gear 282 and a second bevel gear 283. After the rotation motor 281 is started, the first bevel gear 282 drives the second bevel gear 283 fixedly sleeved at the bottom of the rotating rod 26, thereby driving the rotating rod 26 to rotate. A drive gear 29 is also fixedly installed in the middle of the rotating rod 26. During the up and down movement of the display frame 21, the rotation of the drive gear 29 is controlled synchronously.

[0055] The synchronous protection mechanism 3 is located on both side walls of the protective box 1 to provide physical isolation protection. The synchronous protection mechanism 3 includes a sealing plate 31, a connecting frame 32, and a rack plate 34. The sealing plate 31 is located at the openings on both side walls of the protective box 1 to achieve closed storage of the equipment. The outer end of the connecting frame 32 is connected to the sealing plate 31 through a third guide assembly 33. The third guide assembly 33 includes a T-shaped guide frame 331 fixed to the outer end of the connecting frame 32 and a second T-shaped guide groove 332 opened on the inner side wall of the sealing plate 31. The two work together to achieve precise sliding guidance when the sealing plate 31 is translated. The rack plate 34 is fixedly connected to the inner wall of the connecting frame 32 and meshes with the drive gear 29. The module of the drive gear 29 and the rack plate 34 are perfectly matched to ensure precise and stable transmission.

[0056] The synchronous protection mechanism 3 is also equipped with a waterproof plate 35 and a fixing component 36. The waterproof plate 35 is fixedly connected inside the connecting frame 32 and located on the top of the rack plate 34. A drainage groove 351 is provided on the inclined surface of its top. A baffle 352 is provided at the end of the drainage groove 351 away from the sealing plate 31, and a drainage recess 353 is provided at the end near the sealing plate 31, forming a complete rainwater diversion system to shield the synchronous protection mechanism 3 after it is deployed, so as to divert rainwater to the outside of the equipment. The fixing component 36 includes a fixing seat 361 fixed to the bottom of the protective box 1. Mounting holes 362 are provided at both ends of its bottom, which are used to fix the entire equipment at the predetermined working point with anchor bolts, thereby realizing the protection of the equipment during the warning operation.

[0057] Working principle and usage procedure of safety warning equipment for building construction:

[0058] In the initial storage state, the display frame 21 is retracted inside the protective box 1, and the sealing plate 31 is closed on both sides of the protective box 1 to protect the internal components such as the display 24. After the equipment is moved to the work point of the construction site by the casters 11.

[0059] When the rotating motor 281 is started, the power is transmitted to the rotating rod 26 through the meshing of the first bevel gear 282 and the second bevel gear 283, causing it to rotate. The rotational power of the rotating rod 26 is divided into two paths: First, the threaded part 261 at its top rotates, driving the internally threaded tube 25 connected to it to move the entire display frame 21. Under the guidance of the first guide assembly 22, it rises smoothly and vertically until it is fully extended from the top of the protective box 1. At this time, the display 24 and the warning display board 210 face the outside world to provide safety warnings.

[0060] At the same time, the drive gear 29 in the middle of the rotating rod 26 rotates synchronously, driving the two rack plates 34 meshing with it to move in a straight line. The rack plates 34 push the sealing plate 31 through the connecting frame 32, so that it unfolds horizontally to the left and right sides of the protective box 1 under the sliding guidance of the third guide component 33, forming a physical isolation area. The staff uses the mounting holes 362 and anchor bolts to fix the equipment to the ground. During this process, the waterproof plate 35 unfolds into place together with the connecting frame 32. If it rains, the rainwater falls on the slope of the waterproof plate 35, flows along the drainage channel 351 to the drainage recess 353 and is guided to the outside of the equipment, effectively protecting the equipment.

[0061] After the equipment is used up, the control motor 281 is reversed, and the above process is executed in reverse. The display frame 21 is lowered and stored, the sealing plate 31 is closed inward, and the equipment returns to a tight closed state. The anchor bolts can then be released, and the equipment can be easily moved to the next work point via the casters 11.

[0062] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
