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.

[0020] This utility model provides, for example Figure 1-5 The diagram illustrates a reusable safety passage auxiliary device for building construction projects, comprising a protective plate 1 with a groove at the bottom. Two rotating rods 3 are rotatably mounted within the groove. To rotatably mount the rotating rods 3 onto the protective plate 1, rotating slots are formed on the inner walls of both sides of the groove. The two ends of each rotating rod 3 extend into the two rotating slots and are respectively fitted with bearings. The outer rings of the two bearings are fixedly connected to the inner walls of the two rotating rods 3, thus stabilizing the rotation of the rotating rods 3 on the groove. Supporting columns 4 are fixedly mounted on each of the two rotating rods 3. Fixed bases 16 are fixedly mounted on the bottom of the four supporting columns 4. Worm gears 15 are fixedly mounted on each of the two rotating rods 3. A protective box 8 is fixedly installed inside the groove. Two worm gears 2 are rotatably installed inside the protective box 8. The ends of the two worm gears 2 that are far apart from each other are rotatably connected to the inner wall of the groove, and the two worm gears 2 are respectively engaged with two worm wheels 15. The ends of the two worm gears 2 that are close to each other are respectively fixedly installed with first bevel gears 7. A crossbar 6 is rotatably installed inside the protective box 8. In order to make it easier for people to turn the handle 9, a handle 9 is fixedly installed at the bottom of the crossbar 6, and an anti-slip sleeve is fixedly fitted on the handle 9 to prevent people from slipping when turning the handle 9. A second bevel gear 10 is fixedly fitted at the top of the crossbar 6, and the second bevel gear 10 is engaged with the two first bevel gears 7.

[0021] In order to enable the support column 4 to quickly rotate to a vertical downward position to support the protective plate 1, limit iron plates 5 are fixedly installed in the two grooves respectively.

[0022] To enable the protective plates 1 to be quickly aligned and spliced ​​together to form a protective canopy and improve work efficiency, alignment holes 14 are respectively opened on the inner walls of both sides of the groove. Alignment rods 12 are slidably installed in the two alignment holes 14, and magnetic plates 11 are fixedly installed on the adjacent ends of the two alignment rods 12. Tension springs 13 are movably sleeved on the two alignment rods 12. To improve the service life of the tension springs 13, the surfaces of the two tension springs 13 are tin-plated, and the adjacent ends of the two tension springs 13 are fixedly connected to the two magnetic plates 11. The ends that are far apart from each other are fixedly connected to the inner walls of the two grooves respectively. By moving the magnetic plate 11, it separates from the limiting iron plate 5. At this moment, the tension spring 13 changes from the tensioned state to the free state, driving the alignment rod 12 to move out of the alignment hole 14. Then the worker repeats the above operation to rotate the other support column 4 on this device to a vertical downward state, and then moves the two protective plates 1 closer to each other, so that the alignment rod 12 on one protective plate 1 is inserted into the alignment hole 14 on the other protective plate 1, thereby accurately splicing the two protective plates 1 together. In this way, a protective shed is formed by connecting multiple protective plates 1 together.

[0023] The working principle of the reusable safety passage auxiliary device for building construction provided by this utility model is as follows: In the initial state, the magnetic plate 11 is attracted to the limiting iron plate 5, the tension spring 13 is in the stretched state, and the four support columns 4 are horizontally housed in the groove. When the device needs to be used, the rotating handle 9 is rotated clockwise. The rotation of the rotating handle 9 drives the second bevel gear 10 to rotate, which in turn drives the first bevel gear 7 to rotate. The rotation of the first bevel gear 7 drives the worm gear 2 to rotate, which in turn drives the worm wheel 15 to rotate. The rotation of the worm wheel 15 drives the rotating rod 3 to rotate, which in turn drives the four downward support columns 4 to rotate and contact the limiting iron plate 5. At this moment, all four support columns 4 are in a vertical downward state. Then, the magnetic plate 11 is moved to separate from the limiting iron plate 5. At this moment, the tension spring 13 changes from the stretched state to a free state, driving the alignment rod. 12. Move the device out of the alignment hole 14. Then, the worker repeats the above operation to rotate another support column 4 of the device to a vertical downward position. Then, move the two protective plates 1 closer to each other so that the alignment rod 12 on one protective plate 1 is inserted into the alignment hole 14 on the other protective plate 1, thereby accurately splicing the two protective plates 1 together. In this way, multiple protective plates 1 are joined together to form a protective canopy. Then, the fixing base 16 is fixed to the ground by external fixing screws. The assembled protective canopy is then fixed to the ground to complete the protection of the worker. When the protection work is completed and the device is no longer needed, first remove the fixing base 16 from the ground, then turn the rotating handle 9 counterclockwise. Turning the handle 9 rotates the crossbar 6, which in turn rotates the four support columns 4 upwards and stores them into the groove, completing the quick storage of the device and greatly improving work efficiency.

[0024] Compared with related technologies, the reusable safety passage auxiliary device for building construction provided by this utility model has the following beneficial effects:

[0025] This utility model provides a reusable safety passage auxiliary device for building construction projects. By rotating the handle 9 clockwise, the four downward support columns 4 rotate to a vertical downward position. Then, the magnetic plate 11 and the limiting iron plate 5 are moved away from the alignment rod 12 and out of the alignment hole 14. The two protective plates 1 are moved closer to each other, so that the alignment rod 12 on one protective plate 1 is inserted into the alignment hole 14 on the other protective plate 1, accurately splicing the two protective plates 1 together. In this way, multiple protective plates 1 are joined together to form a protective canopy. Then, the fixing base 16 is fixed to the ground by external fixing screws, and the spliced ​​protective canopy is fixed to the ground, completing the protection of workers. When the device is no longer needed, by rotating the handle 9 counterclockwise, the four support columns 4 rotate upward and are stored in the groove, completing the quick storage of the device and greatly improving work efficiency.
