Description

Technical Field

[0001] This utility model relates to the field of road construction safety technology, and in particular to a mobile safety warning device for road marking construction. Background Technology

[0002] Road marking construction refers to the engineering work of drawing various traffic signs on the surface of roads using professional equipment and materials. It can regulate the behavior of traffic participants, clarify the rules of road use, and is an important infrastructure to ensure smooth and safe traffic.

[0003] Road marking construction is mostly carried out on open roads, which often requires occupying part of the lanes and interfering with normal traffic vehicles and pedestrians. This can lead to collisions due to drivers' inattention, excessive speed, or pedestrians' negligence. Therefore, a safety warning device is needed to provide warnings to pedestrians and vehicles.

[0004] Currently available road marking construction safety warning devices mainly consist of a base, bracket, audible alarm, and warning sign. During use, the audible alarm and warning sign provide warnings to pedestrians or vehicles. However, because road marking construction requires marking the entire road surface, the construction area frequently needs to be adjusted. Moving the device requires workers to carry it, a time-consuming and laborious process. To solve this problem, existing technology adds casters to the bottom, allowing workers to easily move the device. However, because of the casters, the device may shift when placed on slopes or subjected to external forces, not only damaging the integrity of the warning area but also potentially causing traffic accidents by entering the driving lane. This reduces the device's practicality and fails to meet user needs. Utility Model Content

[0007] As a further description of the above technical solution: The lifting mechanism includes a hollow column, which is fixedly connected to the top of the base. A rotating rod is rotatably connected to the bottom inner side of the hollow column, and a support plate is fixedly connected to the top of the rotating rod. Curved grooves are formed on both the left and right sides of the top of the support plate. A plug-in post is slidably connected to the inner side of the curved groove, and a locking block is fixedly connected to the top of the plug-in post. Multiple locking slots are equidistantly formed on both the left and right sides of the inner side of the sleeve.

[0008] As a further description of the above technical solution: The control component includes a fixing plate, two fixing plates are respectively fixedly connected to the left and right sides of the outer wall of the spline shaft, a return spring is fixedly connected to one side of the fixing plate, one end of the return spring is fixedly connected to the drive bevel gear, a paddle is rotatably connected to the outer side of the drive bevel gear, and holes are opened on both the left and right sides of the front wall of the housing, and the front end of the paddle passes through the hole.

[0009] As a further description of the above technical solution: The fixing mechanism also includes guide rods, and multiple guide rods are respectively fixedly connected to the front and rear sides of the top of the corresponding anti-slip plate, with the top of the guide rod penetrating the base.

[0010] As a further description of the above technical solution: The fixing mechanism also includes sliding grooves, two of which are respectively opened on the left and right sides of the inner top of the base, and the top of the slider is slidably connected to the sliding grooves.

In this utility model, the spline shaft drives the active bevel gear to rotate, and through the meshing transmission between the active bevel gear and the driven bevel gear, the bidirectional threaded rod rotates, thereby driving the slider to move. The slider pushes the anti-slip plate downward through the connecting rod to lift the device and prevent it from moving. The active bevel gear on one side is driven to move through the paddle, so that the anti-slip plates on both sides can be raised and lowered independently. The height difference between the two anti-slip plates allows the device to remain stable on the ramp.

[0015] 2. In this utility model, the support plate drives the support plate to rotate through the rotating rod. The support plate can push the plug-in column to move through the curved groove, so that the locking block disengages from the slot and is retracted into the hollow column. This allows the height of the sleeve to be adjusted to adapt to different construction environments. The torsion spring will push the support plate to reverse, so that the locking block extends out of the hollow column and engages with the slot. This can fix the position of the sleeve after adjustment. Attached Figure Description

[0018] 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.

[0019] Reference Figure 1 , Figure 3 and Figure 4 The present invention provides an embodiment of a mobile safety warning device for road marking construction, comprising a base 1, a sleeve 4 provided on the upper side of the base 1, a fixing mechanism 2 provided on the inner side of the base 1, the fixing mechanism 2 being used to facilitate the use of the warning device on a ramp, and a lifting mechanism 3 provided on the top of the base 1, the lifting mechanism 3 being used to facilitate adaptation to different construction conditions. The fixing mechanism 2 includes two bidirectional threaded rods 21, which are rotatably connected to the left and right sides of the interior of the base 1, respectively. Slider 22s are threadedly connected to the front and rear sides of the outer walls of the bidirectional threaded rods 21. Rotation of the bidirectional threaded rods 21 drives the sliders 22 to move. A connecting rod 23 is rotatably connected to the bottom of the sliders 22. Anti-slip plates 24 are provided on the left and right sides of the bottom of the interior of the base 1. The top of the anti-slip plates 24 is rotatably connected to the connecting rod 23. Movement of the sliders 22 allows the connecting rod 23 to push the anti-slip plates 24 downwards. A housing 25 is provided on the front side of the base 1. A splined shaft 26 is rotatably connected to the inner side of the housing 25. The right end of the splined shaft 26 passes through the housing 25. The front end of the bidirectional threaded rods 21 passes through the base 1 and is fixedly connected to a driven bevel gear 27. The driven bevel gear 27 drives the bidirectional threaded rods 21 to rotate. Driving bevel gears 28 are slidably connected to the left and right sides of the outer walls of the splined shaft 26. 8 is meshed with the driven bevel gear 27. The spline shaft 26 can drive the driving bevel gear 28 to rotate, and the driven bevel gear 27 will rotate accordingly. Universal wheels 210 are rotatably connected to the four corners of the bottom of the base 1. The universal wheels 210 facilitate the movement of the device by the staff. The control component 29 is provided on the inner side of the outer shell 25. The control component 29 includes a fixing plate 291. The two fixing plates 291 are fixedly connected to the left and right sides of the outer wall of the spline shaft 26, respectively. A return spring 292 is fixedly connected to one side of the fixing plate 291. One end of the return spring 292 is fixedly connected to the driving bevel gear 28. The return spring 292 will push the driving bevel gear 28 to mesh with the driven bevel gear 27. A paddle 293 is rotatably connected to the outer side of the driving bevel gear 28. Holes 294 are opened on the left and right sides of the front wall of the outer shell 25. The front end of the paddle 293 passes through the hole 294. The paddle 293 will drive the driving bevel gear 28 to move. Specifically, when the device is moved to the construction area, rotating the splined shaft 26 causes the driving bevel gear 28 to rotate as well. Since the driving bevel gear 28 meshes with the driven bevel gear 27, when the driving bevel gear 28 starts to rotate, the driven bevel gear 27 will rotate accordingly. The driven bevel gear 27 will further drive the bidirectional threaded rod 21 to rotate. The rotation of the bidirectional threaded rod 21 will then drive the slider 22 to move. During the movement of the slider 22, the connecting rod 23 can push the anti-slip plate 24 downward until it contacts the ground, thereby lifting the device. The purpose is to prevent the device from moving unexpectedly. When using the device on a slope, by moving the lever 293, the lever 293 can drive the driving bevel gear 28 on one side to disengage from the driven bevel gear 27. When the spline shaft 26 continues to rotate, only the anti-slip plate 24 on the other side will move downwards, while the anti-slip plate 24 on the disengaged side will remain in place. A height difference will be formed between the two anti-slip plates 24, so that the device can maintain good stability and safety even on a slope, ensuring that the device will not slip due to the slope during use.

[0020] Reference Figure 1 , Figure 5 and Figure 6 The lifting mechanism 3 includes a hollow column 31, which is fixedly connected to the top of the base 1. A rotating rod 32 is rotatably connected to the bottom inner side of the hollow column 31. A support plate 33 is fixedly connected to the top of the rotating rod 32. The rotating rod 32 will drive the support plate 33 to rotate. Curved grooves 34 are provided on both the left and right sides of the top of the support plate 33. Insertion pins 35 are slidably connected to the inner side of the curved grooves 34. The support plate 33 can push the insertion pins 35 to move through the curved grooves 34. A locking block 36 is fixedly connected to the top of the insertion pin 35. The insertion pin 35 will drive the locking block 36 to move. Multiple locking slots are equidistantly provided on both the left and right sides of the inside of the sleeve 4. 37. One side of the locking block 36 passes through the hollow column 31 and engages with the slot 37. When the locking block 36 moves, it will disengage from the slot 37. A support ring 38 is fixedly connected to the upper middle part of the inner side of the hollow column 31. A torsion spring 39 is fixedly connected to the top of the support ring 38. The top of the torsion spring 39 is fixedly connected to the support plate 33. The torsion spring 39 can push the support plate 33 to rotate in the opposite direction. A support plate 310 is fixedly connected to the bottom front side of the rotating rod 32. A through slot 311 is opened at the bottom front side of the hollow column 31. The front side of the support plate 310 passes through the through slot 311. The support plate 310 will drive the rotating rod 32 to rotate. Specifically, when the device needs to be raised or lowered, the support plate 310 is pulled first. The support plate 310 will drive the rotating rod 32 to start rotating. The rotation of the rotating rod 32 will be transmitted to the support plate 33 connected to it, so that the support plate 33 will also start to rotate synchronously. The support plate 33 can push the plug-in column 35 to move through the curved groove 34. The plug-in column 35 will further drive the connected locking block 36 to move to the inside of the hollow column 31. The locking block 36 will then disengage from the originally engaged slot 37, thereby releasing the fixation restriction on the sleeve 4. At this time, the height of the sleeve 4 can be adjusted to adapt to various construction environments and needs. When the appropriate height is reached, the torsion spring 39 will push the support plate 33 to rotate in the opposite direction, so that the locking block 36 will extend out of the outside of the hollow column 31 and re-engage with the slot 37, thereby fixing the height of the sleeve 4 and ensuring stability during construction.

[0021] Reference Figure 1 , Figure 2 and Figure 3 The fixing mechanism 2 also includes guide rods 212, and multiple guide rods 212 are fixedly connected to the front and rear sides of the top of the corresponding anti-slip plate 24. The top of the guide rods 212 penetrates the base 1. The fixing mechanism 2 also includes slide grooves 211, and two slide grooves 211 are respectively opened on the left and right sides of the top of the inside of the base 1. The top of the slider 22 is slidably connected to the slide grooves 211. The slide grooves 211 can provide guidance for the movement of the slider 22. Specifically, the guide rod 212 can guide the movement of the anti-slip plate 24, so that the anti-slip plate 24 will not deflect, and the slider 22 can only slide inside the groove 211, so that when the bidirectional threaded rod 21 rotates, the slider 22 can move accordingly.

[0022] Reference Figure 1 and Figure 2 A bracket 5 is fixedly connected to the middle of the outer side of the sleeve 4, a storage battery 6 is fixedly connected to the inner side of the bracket 5, a solar panel 7 is fixedly connected to the top of the sleeve 4, the solar panel 7 is electrically connected to the storage battery 6, and the electrical energy generated by the solar panel 7 can enter the storage battery 6. A warning light 8 is fixedly connected to the top of the sleeve 4, an audible warning device 9 is fixedly connected to the front side of the bracket 5, a remote control module 10 is fixedly connected to the top of the bracket 5, and a reflective strip 11 is provided on the outer side of the sleeve 4. Specifically, the solar panel 7 generates electricity, which is stored in the battery 6. The warning light 8 and the audible alarm 9 greatly enhance the warning performance of the device. The operation of the warning light 8 and the audible alarm 9 is controlled by the remote control module 10. The reflective strip 11 can alert passing vehicles at night.

[0023] Working principle: When the device is moved to the construction area, rotating the splined shaft 26 will drive the driving bevel gear 28 to rotate. Since the driving bevel gear 28 meshes with the driven bevel gear 27, the driven bevel gear 27 will drive the double-threaded rod 21 to rotate as the driving bevel gear 28 rotates. The double-threaded rod 21 will then drive the slider 22 to move. When the slider 22 moves, it can push the anti-slip plate 24 downward to contact the ground through the connecting rod 23, thus lifting the device and preventing it from moving. This is especially important when using the device on a ramp. By moving the paddle 293, the paddle 293 will cause the driving bevel gear 28 on one side to disengage from the driven bevel gear 27, so that when the spline shaft 26 rotates, only the anti-slip plate 24 on one side will move downward. The height difference between the two anti-slip plates 24 allows the device to remain stable on the ramp. During the use of the device, the warning effect of the device can be improved by the sound alarm 9 and the warning light 8. The device is powered by the solar panel 7 and the battery 6, reducing dependence on external power and reducing the cost of using the device. Furthermore, when the device needs to be raised or lowered, the support plate 310 is pulled, which drives the rotating rod 32 to rotate. The rotating rod 32 drives the support plate 33 to rotate. When the support plate 33 rotates, it can push the insertion post 35 to move through the curved groove 34. The insertion post 35 will drive the locking block 36 to move to the inside of the hollow post 31, thereby disengaging from the slot 37. Then, the height of the sleeve 4 can be adjusted to adapt to different construction environments. After the adjustment is completed, the torsion spring 39 will push the support plate 33 to reverse, so that the locking block 36 extends out of the hollow post 31 and engages with the slot 37, thereby fixing the height of the sleeve 4.
