[0016] Compared with the prior art, the beneficial effects of the present invention are: the construction safety protection device has the following advantages:

[0017] 1. When the support frame contacts the ground, the applied pressure will cause the base to slide along the sliding hole and compress the spring.

The middle of the rotating shafts 26 are fixed with gears 25. The tooth grooves 22 are respectively opened at the left and right ends of the mounting plate 3. The tooth grooves 22 are meshed with adjacent gears 25. The height adjustment mechanism 2 also includes guide grooves 21 and guide rails 27. The guide rails 27 are all opened on the inner side of the mounting frame 1. The guide grooves 21 are connected to the inner side of the mounting frame 1. 1 is opened at the left and right ends of the mounting plate 3, the inner walls of the guide groove 21 are slidably connected to the outer surface of the adjacent guide rail 27, the height adjustment mechanism 2 also includes a driving mechanism 23, the driving mechanism 23 includes a worm 231, a rotating shaft 232 and a worm gear 234, the rotating shaft 232 is rotatably connected to the right inner wall of the mounting groove 24 at the right end, the left end of the rotating shaft 232 is fixedly connected to the worm 231, and the worm gear 234 is fixedly sleeved on the front end of the rotating shaft 26 at the right end, and the worm gear 234 is meshed with the worm 231. The driving mechanism 23 also includes The motor 233 is mounted on the upper right side of the mounting frame 1 at the right end by bolts. The left end of the output shaft of the motor 233 is fixedly connected to the right end of the rotating shaft 232. The input end of the motor 233 is electrically connected to the output end of the single chip microcomputer 5. When the height of the construction site environment changes, the motor 233 is controlled by the single chip microcomputer 5. The output shaft of the motor 233 drives the rotating shaft 232 to rotate. The rotating shaft 232 drives the worm 231 to engage and rotate with the worm gear 234, so that the worm gear 234 starts to rotate. The rotation of the worm gear 234 drives the right The rotating shaft 26 at the end rotates and drives the gear 25 to engage with the tooth groove 22 at the right end. The rotation of the gear 25 causes the mounting plate 3 to move upward along the guide groove 21. At the same time, the tooth groove 22 at the left end engages with the gear 25 at the left end, ensuring that the mounting plate 3 remains stable when moving upward to prevent it from tilting or shifting. When the mounting plate 3 moves to the specified height, the warning sign 4 will reach a height corresponding to the height of the construction site environment. At this time, the position of the warning sign 4 can effectively convey the warning information and ensure that the safety reminder of the construction site is in place.

[0028] The support mechanism 6 is arranged at the four corners of the lower surface of the support frame 7. The support mechanism 6 includes a slide post 61, a base 62 and a slide hole 64. The slide hole 64 is respectively opened at the four corners of the lower surface of the support frame 7. The inner wall of the slide hole 64 is slidably connected to the slide post 61, and the bottom end of the slide post 61 is fixedly connected to the base 62. The support mechanism 6 also includes a spring 63. The spring 63 is fixedly connected between the upper surface of the base 62 and the adjacent end of the lower surface of the support frame 7. The spring 63 is sleeved on the outer surface of the slide post 61. When the construction warning sign is placed at a place where a warning message needs to be conveyed on the construction site, the applied pressure will be transmitted to the base 62. The base 62 slides along the inner wall of the slide hole 64 due to the pressure and compresses the spring 63. The compression of the spring 63 will generate a reaction force. This force can adjust the height of the support frame 7 so that it can adapt to the unevenness of the ground, thereby being able to maintain a stable contact height when the ground is uneven, providing a stable support for the warning sign.

[0029] The working principle of a construction safety protection device provided by the present invention is as follows: first, a construction warning sign is placed at a place where a warning message needs to be conveyed on the construction site. When the support frame 7 contacts the ground, the applied pressure will be transmitted to the base 62. Due to the pressure, the base 62 slides along the inner wall of the sliding hole 64 and compresses the spring 63. The compression of the spring 63 will generate a reaction force. This force can adjust the height of the support frame 7 so that it can adapt to the unevenness of the ground, thereby maintaining a stable contact height under uneven ground conditions, providing a stable support for the warning sign. When the height of the construction site environment changes, the motor 233 is controlled by the single-chip microcomputer 5, and the output of the motor 233 is output. The output shaft drives the rotating shaft 232 to rotate, and the rotating shaft 232 drives the worm 231 to engage and rotate with the worm wheel 234, causing the worm wheel 234 to start rotating. The rotation of the worm wheel 234 drives the rotating shaft 26 at the right end to rotate, and drives the gear 25 to engage with the tooth groove 22 at the right end. The rotation of the gear 25 causes the mounting plate 3 to move upward along the guide groove 21. At the same time, the tooth groove 22 at the left end engages with the gear 25 at the left end, ensuring that the mounting plate 3 remains stable when moving upward to prevent it from tilting or offsetting. When the mounting plate 3 moves to the specified height, the warning sign 4 will reach a height corresponding to the height of the construction site environment. At this time, the position of the warning sign 4 can effectively convey warning information to ensure that safety reminders at the construction site are in place.
