[0020] Furthermore, the first rotating body 11 is meshed and rotationally connected with the second rotating body 13 .

[0021] Furthermore, preferably, both the first rotating body 11 and the second rotating body 13 are selected to be gears, and the transmission between the first rotating body 11 and the second rotating body 13 is the gear transmission in the industry, and the gear transmission has the following advantages: 1.

Compact structure: the gear transmission device is usually compact in design and can transmit greater power in a smaller space; 3. Strong load-bearing capacity: the gears can withstand larger loads; 4. Long service life: high-quality gears have a longer service life if properly lubricated and maintained.

[0022] Furthermore, the lower end surface of the second rotating body 13 is fixedly connected with a sleeve 14, the inner wall of the sleeve 14 is provided with a thread, the inner thread of the sleeve 14 is rotatably connected with a lifting rod 15, the lower end of the lifting rod 15 is fixedly connected with a universal wheel 17 through a movable top plate 16, and the bottom plate of the base 1 is provided with two fourth through grooves 10b, and the fourth through grooves 10b are placed below the universal wheel 17 to prevent motion interference when the universal wheel 17 descends.

[0024] Furthermore, a connecting block 18 is fixedly connected to one side of the base 1, and the cross-sectional shape of the connecting block 18 is the same as the cross-sectional shape of the third through groove 10a. A hanging ear 19 is provided on one side of the second connecting plate 2b, and a pulley 20 is provided at the lower end of the second connecting plate 2b. A warning light 21 is also provided at the top of the support frame 1.

[0027] In the first embodiment, during the road construction process, the warning light located above the support frame 1 is in working condition, which serves as a warning to pedestrians and vehicles on the road. When the device is used and stored, the staff rotates the rotating wheel 6, and the rotating wheel 6 drives the rotating shaft 4 to rotate, thereby driving the first rotating body 11 and the second rotating body 13 to rotate, and driving the sleeve 14 to rotate. Since the lifting rod 15 is threadedly connected to the sleeve 14, the lifting rod 15 and the universal wheel 17 move downward relative to the second rotating body 13 until the universal wheel 13 abuts the ground, which is convenient for the staff to move the device. At the same time, the rotating shaft 4 rotates to drive the first lifting slider 5 and the second lifting slider 6 to move closer to the middle of the rotating shaft 4. Since the lifting connection member 7 is connected to the first lifting slider 5 and the second lifting slider 6, the lifting connection member 7 is connected to the first lifting slider 5 and the second lifting slider 6. The two lifting sliders 6 and the first connecting plate 2a are hinged, thereby driving the first enclosure 2 to move toward the support frame 1 under the support of the pulley 20. When the first enclosure 2 moves toward the support frame 1, the first partition plate 2d moves along the second slide groove 3a toward the support frame 1 until the top of the first partition plate 2d abuts against the inner side of the second slide groove 3a. At this time, the limiting slider 9 fixedly connected to the second enclosure 3 moves along the second through groove 1b until the limiting slider 9 moves to the top of the second through groove 1b. At this time, the second connecting plate 2b crosses and overlaps with the second enclosure 3, which greatly saves the storage area of ​​the device.

[0028] In the second embodiment: Furthermore, the second enclosure 3 and one side of the support frame 1 can be slidably connected through a linear guide and a slider. The linear guide and slider are a common mechanical transmission and guiding device, which has the following advantages: 1. Strong load-bearing capacity: Modern linear guide design can withstand large radial and axial loads, and is suitable for heavy-load applications; 2. Smooth operation: The design of the linear guide and slider enables it to run smoothly with less vibration and noise; 3. Low friction resistance: Linear guides usually use rolling contact (such as balls or rollers) with a low friction coefficient, which reduces energy loss and improves movement efficiency. Low friction also means lower wear rate and extended service life.

[0029] Furthermore, the inner cavity of the base 1 is built with a turbine worm, a reducer and a drive motor, the output shaft of the drive motor is drive-connected to the reducer, one end of the turbine worm structure is drive-connected to the rotating shaft 4, and the other end of the turbine worm structure is drive-connected to the output shaft of the reducer, wherein the drive motor is connected to a controller, and the controller controls the forward and reverse rotation of the drive motor to achieve the forward and reverse rotation of the rotating shaft 4, thereby achieving the deployment and storage of the first enclosure 2 and the second enclosure 3, and the raising and lowering of the universal wheel 17, which can save manpower and material resources.

[0030] Working principle: The municipal road construction safety protection device provided by the invention comprises a support frame 1, a first enclosure 2 and a second enclosure 3. The support frame 1 is hollow, and first through slots 1a are provided on both sides of the support frame 1 along the length direction, wherein the first through slots 1a are connected with the inner cavity of the support frame 1, and the upper and lower ends of the first through slots 1a do not penetrate the top plate and the bottom plate of the support frame 1, and the inner cavity of the support frame 1 is rotatably connected with a rotating shaft 4, and a bearing is provided at the connection between the rotating shaft 4 and the support frame 1, so as to facilitate the rotatable connection between the rotating shaft 4 and the support frame 1.

[0031] Specifically, during the road construction process, the warning light located above the support frame 1 is in working condition, which serves as a warning to pedestrians and vehicles on the road. When the device is used and stored, the staff rotates the rotating wheel 6, and the rotating wheel 6 drives the rotating shaft 4 to rotate, thereby driving the first rotating body 11 and the second rotating body 13 to rotate, and driving the sleeve 14 to rotate. Since the lifting rod 15 is threadedly connected to the sleeve 14, the lifting rod 15 and the universal wheel 17 move downward relative to the second rotating body 13 until the universal wheel 13 abuts the ground, which is convenient for the staff to move the device. At the same time, the rotating shaft 4 rotates to drive the first lifting slider 5 and the second lifting slider 6 to move closer to the middle of the rotating shaft 4. Since the lifting connector 7 is connected to the first lifting slider 5 and the second lifting slider 6, the lifting connector 7 is connected to the first lifting slider 5 and the second lifting slider 6. The two lifting sliders 6 and the first connecting plate 2a are hinged, thereby driving the first enclosure 2 to move toward the support frame 1 under the support of the pulley 20. When the first enclosure 2 moves toward the support frame 1, the first partition plate 2d moves along the second slide groove 3a toward the support frame 1 until the top of the first partition plate 2d abuts against the inner side of the second slide groove 3a. At this time, the limiting slider 9 fixedly connected to the second enclosure 3 moves along the second through groove 1b until the limiting slider 9 moves to the top of the second through groove 1b. At this time, the second connecting plate 2b crosses and overlaps with the second enclosure 3, which greatly saves the storage area of ​​the device.
