Description

Technical Field

[0001] This invention relates to the field of engineering management equipment technology, and in particular to an engineering management safety warning device. Background Technology

[0002] Safety warning devices play a crucial role in engineering management. Through printed warning graphics and text, they effectively remind workers and passersby of potential dangers, ensuring construction safety and the safety of personnel and property. However, existing engineering management safety warning devices have many problems. On the one hand, long-term exposure to the outdoor environment makes the surface of the warning boards prone to dust accumulation, resulting in blurred warning graphics and text, reducing the warning effect. On the other hand, traditional support structures are mostly fixed and unchanging, making it difficult to adapt to different terrains and installation heights. Moreover, they are unstable when subjected to external impacts (such as strong winds, vehicle collisions, etc.), and are prone to tipping over, which not only affects the normal use of the warning devices but may also create safety hazards.

[0003] Therefore, there is a need for an engineering management safety warning device that can automatically clean the surface of the warning board and has a stable and adjustable support structure. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the above-mentioned technologies. The technical solution adopted by this invention is as follows:

[0005] An engineering management safety warning device, comprising:

[0006] Warning signs are used to print warning graphics and text.

[0007] A cleaning structure, installed on the warning board body, is used to clean the surface of the warning board body;

[0008] The supporting structure connects to the warning board and provides support for the warning board.

[0009] The cleaning structure includes connecting frames and roller brushes. Four connecting frames are arranged in pairs on both sides of the warning board body, and are respectively located near the upper and lower ends of the warning board. Each connecting frame has a bearing 1 at the end away from the warning board. Threaded shafts are placed at the upper and lower ends of the warning board. The threaded shafts are movably inserted into two of the bearings 1. A motor 1 is located at one end of the threaded shaft, and the motor 1 is fixedly connected to the connecting frame. Threaded tubes are threaded onto the two threaded shafts. A bearing 2 is located on the side of the threaded tube away from the warning board. The roller brush is perpendicularly attached to the surface of the warning board body. Connecting shafts are located at both the upper and lower ends of the roller brush. Two connecting shafts are movably inserted into two of the bearings 2. A motor 2 is located at the end of one connecting shaft away from the roller brush, and the motor 2 is fixedly connected to one of the threaded tubes.

[0010] The support structure includes a support tube, a support rod inserted inside the top of the support tube, a fixing bolt threaded on the side of the support tube near the top, one end of the fixing bolt abutting against the side of the support rod, a sleeve movably fitted on the support rod near the top, a fixing bolt threaded on the side of the sleeve, one end of the fixing bolt abutting against the side of the support rod, and the sleeve being connected and fixed to the back of the warning plate by bolts.

[0011] Preferably, the threaded tube is adapted to the threaded shaft, and the threaded tube can rotate on the threaded shaft body.

[0012] Preferably, the support rod is adapted to the support tube, and the support rod body can be freely inserted and removed inside the support tube body.

[0013] Preferably, the bottom end of the support pipe is provided with a connecting plate, and a base plate is placed parallel below the connecting plate. The base plate is provided with a fixing rod near the corner. A support shaft is movably inserted into the connecting plate near the corner, and the bottom end of the support shaft is connected and fixed to the upward working surface of the base plate. A buffer spring is sleeved on the support shaft, and the upper and lower ends of the buffer spring are connected to the connecting plate and the base plate, respectively.

[0014] The beneficial effects of this invention are as follows:

[0015] Automatic cleaning function: The first motor in the cleaning structure drives the threaded shaft to rotate, causing the threaded tube to move axially along the threaded shaft, which drives the roller brush to scan the surface of the warning board laterally. At the same time, the second motor drives the roller brush to rotate, realizing automatic cleaning of the surface of the warning board without manual operation, effectively keeping the warning graphics and text clearly visible and improving the warning effect.

[0016] Height and angle adjustable: In the support structure, the support rod can be freely inserted and removed inside the support tube, and the height can be locked by fixing bolts to realize the adjustment of the vertical height of the warning plate. The sleeve is fitted on the top of the support rod, and the angle can also be locked by fixing bolts, so the tilt angle of the warning plate can be flexibly adjusted to adapt to different installation environments and viewing angle requirements, thus expanding the application range of the warning device.

[0017] Stable support: The buffer springs at the bottom of the support structure can effectively absorb ground vibrations and reduce the impact of external forces on the warning device. At the same time, the fixing rods on the base plate can be fixed to the ground with ground nails or bolts, which enhances the wind resistance and stability of the device, prevents the warning device from tipping over when subjected to external forces, and improves the safety of use.

The upper and lower ends of the buffer spring 308 are connected to the connecting plate 305 and the base plate 306, respectively.

[0036] Working principle and usage process of this invention:

[0037] Height adjustment: When the height of the warning board needs to be adjusted, loosen the fixing bolts on the support tube, move the support rod up or down inside the support tube to the appropriate height position, and then tighten the fixing bolts to fix the support rod inside the support tube, thereby realizing the adjustment of the vertical height of the warning board;

[0038] Angle adjustment: To adjust the tilt angle of the warning plate, loosen the fixing bolt on the sleeve, rotate the sleeve to the required angle, and then tighten the fixing bolt to fix the sleeve to the support rod, thereby driving the warning plate to adjust to a suitable tilt angle to meet different warning viewing angle requirements.

[0039] Stable installation: When installing the warning device, place the base plate on the ground and fix the fixing rod on the base plate to the ground with ground nails or bolts to ensure the base plate is stable. The support tube is connected to the base plate through the connecting plate, support shaft and buffer spring. When the device is subjected to ground vibration or external impact, the buffer spring can compress and deform to absorb the impact force, reduce the impact of vibration on the warning device and improve the stability of the device. Finally, the sleeve is connected and fixed to the back of the warning plate with bolts to complete the installation of the entire warning device.

[0040] Cleaning structure operation process:

[0041] Start-up preparation: When dust, stains, or other conditions appear on the surface of the warning board that affect the clarity of the warning graphics, the operator starts motor one and motor two in the cleaning structure;

[0042] Lateral movement of the roller brush: When the motor starts running, it drives the threaded shaft connected to it to rotate. Since the threaded tube is adapted to the threaded shaft and the thread is sleeved, under the action of the thread transmission principle, the threaded tube moves along the axial direction of the threaded shaft. Because the four connecting brackets are set in pairs on both sides of the warning plate to support the threaded shaft, the movement of the threaded tube will drive the roller brush to perform lateral scanning on the surface of the warning plate, so that the roller brush can cover the lateral area of ​​the warning plate.

[0043] Roller brush self-rotation cleaning: Motor 2 starts synchronously, driving the roller brush to rotate in bearing 2 through the connecting shaft. The roller brush is vertically attached to the surface of the warning board, and its bristles are in close contact with the surface of the warning board. During the rotation of the roller brush, the bristles continuously rub the surface of the warning board, separating dust, stains and other dirt from the surface of the warning board.

[0044] Comprehensive cleaning: Under the dual action of the lateral movement and rotation of the roller brush, the surface of the warning board can be thoroughly cleaned. As the threaded tube moves from one end to the other on the threaded shaft, the roller brush completes one lateral cleaning action. By controlling the forward and reverse rotation of motor one, the threaded tube can move back and forth to clean the surface of the warning board multiple times to ensure the cleaning effect.

[0045] Cleaning complete: After the warning panel surface is cleaned, the operator turns off motor one and motor two. The motors stop running, the threaded shaft and roller brush lose their power source, the threaded tube stops moving on the threaded shaft, and the roller brush also stops rotating, thus completing this cleaning process.
