Abstract
Description
Technical Field
[0001] This utility model relates to the field of warning sign technology, specifically a construction warning sign frame. Background Technology
[0002] During construction, construction warning signs serve as crucial facilities to remind construction workers and those in the surrounding area to be aware of safety and avoid dangerous areas. Their warning effect directly impacts construction safety and the safety of people and property. Currently, most construction warning signs on the market adopt a column-supported structure, achieving their warning function through reflective paint spraying and the placement of warning slogans or patterns.
[0003] Existing warning sign racks lack auxiliary cleaning functions. However, construction sites are complex environments, often containing large amounts of dust, sand, and other pollutants. Traditional warning sign boards are exposed to such environments for extended periods, and their surfaces are easily covered with dust, mud, and other stains. This weakens the reflective effect of the reflective coating and makes the warning patterns and text unclear. Once the visibility of the warning sign boards is reduced, construction workers and those in the surrounding area will find it difficult to quickly identify dangerous information, thereby increasing the risk of safety accidents. Therefore, we propose a new construction warning sign rack. Utility Model Content
[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a construction warning sign rack that is easy to clean. This solves the problem that existing warning sign racks lack auxiliary cleaning functions. However, construction sites are complex environments, often containing large amounts of dust, sand, and other pollutants. Traditional warning signs are exposed to this environment for a long time, and their surfaces are easily covered with dust, mud, and other stains. This weakens the reflective effect of the reflective coating and makes the warning patterns and text unclear. Once the visibility of the warning signs is reduced, construction workers and people in the surrounding area cannot quickly identify the danger information, thereby increasing the risk of safety accidents.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a construction warning sign frame, comprising a support rod, a limiting rod fixedly connected to one side of the support rod, a sign plate inserted into the bottom of the limiting rod, a water tank provided inside the support rod, a water pump connected to the bottom of the back of the water tank, a drain pipe connected to one side of the water pump, a nozzle connected to one side of the drain pipe, a hollow rod provided at the bottom of the sign plate, a motor fixedly connected to the right side of the back of the hollow rod, a drive pulley fixedly connected to the output end of the motor, a belt sleeved on the surface of the drive pulley, a driven pulley sleeved on the left side of the inner surface of the belt, a fixing rod fixedly connected to the bottom of the belt, and a brush rod fixedly connected to one side of the fixing rod.
[0006] Preferably, a housing is fixedly connected to the other side of the support rod, the bottom of the housing is fixedly connected to the water tank, hollow blocks are connected to both sides of the top of the housing, a rotating shaft is movably connected to the central axis of the top of the housing, a lead screw is movably connected to both sides of the inner cavity of the housing, a threaded sleeve is threaded to the top of the surface of the lead screw, a connecting rod is fixedly connected to the top of the threaded sleeve, a crossbar is fixedly connected to one side of the connecting rod, the top of the crossbar is inserted into the marking plate, and the bottom of the crossbar is fixedly connected to the hollow rod.
[0007] Preferably, the inner cavity of the driven pulley is fixedly connected to a connecting shaft, and the rear side of the connecting shaft is movably connected to the hollow rod through a first bearing.
[0008] Preferably, the bottom of the support rod is fixedly connected to a base, and a mounting hole is provided on one side of the base.
[0009] Preferably, the bottom of the rotating shaft is movably connected to the housing via a second bearing, and the bottom of the lead screw is movably connected to the housing via a third bearing.

[0011] Preferably, a timing pulley is fixedly connected to the bottom of both the surface of the rotating shaft and the surface of the lead screw, and a timing belt is engaged with the surface of the timing pulley.
[0012] Preferably, the inner cavity of the fixing rod is slidably connected to a prism, and both sides of the prism are fixedly connected to the hollow rod.
[0013] Compared with the prior art, this utility model provides a construction warning sign frame, which has the following beneficial effects:
[0014] 1. When this utility model is used for warning purposes, water is injected into the inner cavity of the water tank. When cleaning is required, the water pump is started through the external controller to extract the water from the inner cavity of the water tank. Then, the water is sprayed onto the front of the signboard through the drain pipe and the nozzle. At the same time, the motor is started, which drives the drive pulley to rotate. Through the cooperation of the driven pulley, the drive pulley drives the belt to rotate, which in turn drives the fixed rod to move. The fixed rod drives the brush rod to move, and the brush rod cleans the front of the signboard.
[0015] 2. When the signboard needs to be replaced, the rotating shaft is rotated, and the timing pulley and timing belt work together to drive the lead screw to rotate. The lead screw drives the threaded sleeve to move, the threaded sleeve drives the connecting rod to move, the connecting rod drives the crossbar to move, and the crossbar drives the signboard to descend, so that the signboard moves away from the limit bar. Then the signboard is moved upward to separate the signboard from the crossbar, thus completing the disassembly work and facilitating the replacement of the signboard. Attached Figure Description

Both sides of the prism are fixedly connected to the hollow rod 12.
[0025] The specific function of this technical solution is as follows: When performing warning work, water is injected into the inner cavity of the water tank 20. When cleaning is required, the water pump 21 is started through the external controller to extract the water from the inner cavity of the water tank 20. Then, the water is sprayed onto the front of the signboard 3 through the drain pipe 22 and the nozzle 23. At the same time, the motor 14 is started, which drives the drive pulley 15 to rotate. Through the cooperation of the driven pulley 17, the drive pulley 15 drives the belt 16 to rotate, which in turn drives the fixed rod 18 to move. The fixed rod 18 drives the brush rod 19 to move, and the brush rod 19 cleans the front of the signboard 3.
[0026] Example 2, based on Example 1, the present invention as follows: Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, a housing 4 is fixedly connected to the other side of the support rod 1. The bottom of the housing 4 is fixedly connected to the water tank 20. Hollow blocks 5 are connected to both sides of the top of the housing 4. A rotating shaft 6 is movably connected to the central axis of the top of the housing 4. A lead screw 7 is movably connected to both sides of the inner cavity of the housing 4. A threaded sleeve 10 is threadedly connected to the top of the surface of the lead screw 7. A connecting rod 11 is fixedly connected to the top of the threaded sleeve 10. A crossbar 13 is fixedly connected to one side of the connecting rod 11. The top of the crossbar 13 is inserted into the marking plate 3. The bottom of the crossbar 13 is fixedly connected to the hollow rod 12. The bottom of the rotating shaft 6 is movably connected to the housing 4 through a second bearing. The bottom of the lead screw 7 is movably connected to the housing 4 through a third bearing. A sliding rod is slidably connected to one side of the inner cavity of the threaded sleeve 10. The bottom of the sliding rod is fixedly connected to the hollow block 5. A synchronous pulley 8 is fixedly connected to the surface of the rotating shaft 6 and the bottom of the surface of the lead screw 7. A synchronous belt 9 is engaged with the surface of the synchronous pulley 8.
[0027] The specific function of this technical solution is as follows: When the sign plate 3 needs to be replaced, the rotating shaft 6 is rotated, and through the cooperation of the synchronous pulley 8 and the synchronous belt 9, the lead screw 7 is driven to rotate. The lead screw 7 drives the threaded sleeve 10 to move, the threaded sleeve 10 drives the connecting rod 11 to move, the connecting rod 11 drives the crossbar 13 to move, and the crossbar 13 drives the sign plate 3 to descend, thereby moving the sign plate 3 away from the limit rod 2. Then the sign plate 3 is moved upward, so that the sign plate 3 is separated from the crossbar 13, thereby completing the disassembly work and facilitating the replacement of the sign plate 3.
[0028] Working principle: When performing warning work, water is injected into the inner cavity of the water tank 20. When cleaning is required, the water pump 21 is started by the external controller to draw out the water in the inner cavity of the water tank 20. Then, the water is sprayed onto the front of the signboard 3 through the drain pipe 22 and the nozzle 23. At the same time, the motor 14 is started, which drives the drive pulley 15 to rotate. Through the cooperation of the driven pulley 17, the drive pulley 15 drives the belt 16 to rotate, which in turn drives the fixed rod 18 to move. The fixed rod 18 drives the brush rod 19 to move, and the brush rod 19 cleans the front of the signboard 3.
[0029] When it is necessary to replace the sign plate 3, rotate the shaft 6. Through the cooperation of the synchronous pulley 8 and the synchronous belt 9, the lead screw 7 will rotate. The lead screw 7 will drive the threaded sleeve 10 to move. The threaded sleeve 10 will drive the connecting rod 11 to move. The connecting rod 11 will drive the crossbar 13 to move. The crossbar 13 will drive the sign plate 3 to descend, thereby moving the sign plate 3 away from the limit rod 2. Then, move the sign plate 3 upward to separate the sign plate 3 from the crossbar 13, thereby completing the disassembly work and facilitating the replacement of the sign plate 3.
