DETAILED DESCRIPTION

[0024] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0025] See also Figure 1-3 The present invention provides a technical solution: a safety protection device for municipal construction. It includes a base plate 110, four sets of movable adjustment components are installed at the bottom of the base plate 110, two sets of lifting components are installed at the bottom of the base plate 110, and warning components are installed at the ends of the two lifting components away from the base plate 110, and adjustment components are installed on the warning components;

[0026] The movable adjustment component includes a movable groove 210, which is opened at the bottom of the base plate 110. A first threaded rod 220 is rotatably connected to the top inner wall of the movable groove 210. A first worm gear 230 is installed on the first threaded rod 220. A connecting rod 240 is threadedly connected to the first threaded rod 220. A guide block 241 is installed on the side wall of the connecting rod 240. The end of the connecting rod 240 away from the first threaded rod 220 passes through the outside of the base plate 110, and a movable wheel 250 is installed on the end of the connecting rod 240 away from the first threaded rod 220.

[0027] When adjusting the height of the base plate 110, by rotating the first handle 270, the first handle 270 drives the first worm 260 to rotate, and the first worm 260 drives the first threaded rod 220 to rotate by engaging with the first worm wheel 230, so that the first threaded rod 220 drives the connecting rod 240 to move vertically, thereby adjusting the height of the moving wheel 250, and by adjusting the height of the four sets of moving wheels 250, the four sets of moving wheels 250 can meet the inclination requirements of the ground, so that the base plate 110 remains horizontal, so that the base plate 110 is not easy to fall when subjected to external forces, thereby improving the stability of the protective device. The moving wheel 250 adopts a universal wheel design, which is convenient for all-round movement. At the same time, the moving wheel 250 has a locking function to ensure that the position of the protective device can be moved when needed, which facilitates flexible arrangement and transfer at the construction site and reduces the labor intensity of the staff in moving the protective device.

[0028] A first worm 260 is rotatably connected to an outer wall of one side of the movable groove 210. The first worm 260 meshes with the first worm wheel 230. One end of the first worm 260 extends to the outside of the base plate 110, and a first turning handle 270 is mounted on one end of the first worm 260. The first worm 260 and the first worm wheel 230 drive the first threaded rod 220 to rotate, making the lifting and lowering of the movable wheel 250 more stable. The combination of the first worm 260 and the first worm wheel 230 provides a self-locking function, thereby preventing the first threaded rod 220 from rotating in the opposite direction, ensuring that the movable wheel 250 remains stable during use.

[0029] A guide groove 211 is formed on the inner wall of the other side of the movable groove 210. A guide rod 212 is mounted in the guide groove 211. The guide rod 212 is slidably connected to a guide block 241. The guide rod 212 guides the movement of the connecting rod 240 so that during the rotation of the first threaded rod 220, the connecting rod 240 does not rotate with the first threaded rod 220 due to friction, allowing the connecting rod 240 to move vertically.

[0030] A limit plate 280 is mounted on the inner wall of the other side of the movement groove 210. The limit plate 280 is located between the first worm gear 230 and the connecting rod 240. The limit plate 280 prevents the connecting rod 240 from colliding with the first worm gear 230 during movement, thereby limiting the position of the connecting rod 240 and preventing damage to the connecting rod 240 and the first worm gear 230.

[0031] The lifting assembly includes a lifting rod 310 mounted on top of the base plate 110. A second threaded rod 320 is threadedly connected to the end of the lifting rod 310 away from the base plate 110. The end of the second threaded rod 320 away from the lifting rod 310 is pivotally connected to the warning assembly. By rotating the second threaded rod 320, it moves vertically within the lifting rod 310, thereby adjusting the distance between the fixed plate 410 and the base plate 110 and adjusting the height of the warning sign 420. This allows the warning sign 420 to be adjusted to suit different construction site requirements and terrain conditions.

[0032] The warning assembly includes a fixed plate 410, which is rotatably connected to the two sets of second threaded rods 320. A warning sign 420 is mounted on the top of the fixed plate 410. The warning sign 420 is provided with a clear warning mark, such as a reflective strip or a warning light, which can provide a significant warning at night or in low-visibility environments, thereby reducing the probability of accidents.

[0033] The adjustment assembly includes an adjustment chamber 510, which is defined within the fixed plate 410. A second worm 520 is rotatably connected to the adjustment chamber 510. One end of the second worm 520 extends outside the fixed plate 410, and a second turning handle 530 is mounted on one end of the second worm 520. Two sets of rotating rods 540 are rotatably connected to the bottom inner wall of the adjustment chamber 510. One end of each set of rotating rods 540 extends outside the fixed plate 410, and one end of each set of rotating rods 540 is mounted on the end of each set of second threaded rods 320 away from the lifting rod 310. The other end of each set of rotating rods 540 is mounted on a second worm gear 550, and both sets of second worm gears 550 mesh with the second worm 520. By rotating the second handle 530, the second handle 530 drives the second worm 520 to rotate, and under the meshing action of the second worm 520 and the second worm wheel 550, the rotating rod 540 is driven to rotate, so that the rotating rod 540 drives the second threaded rod 320 to rotate, so that the two groups of second threaded rods 320 can move simultaneously in the lifting rod 310, making the height adjustment of the warning sign 420 more stable, and at the same time making the height of the warning sign 420 less likely to deviate, thereby improving the stability of the height adjustment of the warning sign 420.

[0034] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
