[0002] Construction is an important stage in the implementation of engineering construction, involving the entire process of converting design drawings into specific buildings. During the construction process, construction site safety passages are often required.

[0003] After searching, the announcement number is CN214273007U, and the name is a safety passage for construction sites. It solves the problem that the existing safety passages for construction sites cannot be adjusted in height, making it difficult to connect with tables of different heights according to actual usage and unfavorable for use. Through research and analysis, it is found that although there is the advantage of adjustable height, there are still the following disadvantages to a certain extent.

[0004] For example, the safety passage used for construction sites mentioned above usually does not have an elastic support mechanism during use, which results in it being unable to provide good support stability after the height is adjusted, and usually does not have a snap-on quick assembly structure, which may affect the main body installation efficiency to a certain extent. In order to solve the above technical problems, we have designed a quick-installation safety passage for construction sites. Utility Model Content

[0020] See also Figure 1-Figure 4 , a quickly installed safety passage for a construction site, comprising a placement base plate 1 and an external contact member 2, a second stepping pedal 9 and a first stepping pedal 4 are respectively provided on both sides of the top of the placement base plate 1, and a fixed mounting plate 6 is welded on the left sides of the front and rear sides of the first stepping pedal 4, and the front side of the fixed mounting plate 6 is connected to a servo motor 7 by bolts, and the output end of the servo motor 7 passes through the rear side of the second stepping pedal 9 and is movably connected to the rear fixed mounting plate 6 by a bearing. An elastic support mechanism 22 is provided on the left side of the top of the placement base plate 1, and a hydraulic cylinder telescopic frame 5 is connected to the right side of the top of the placement base plate 1 by bolts. By setting the hydraulic cylinder telescopic frame 5, the support height of the first stepping pedal 4 can be lifted by hydraulic lifting, thereby achieving a better height lifting effect. The elastic support mechanism 22 includes a shell 8, the bottom of the shell 8 is welded to the top of the placement base plate 1, and a clamping mechanism 23 is provided at the bottom of the first stepping pedal 4. The clamping mechanism 23 includes a dual-axis motor 20, and the top of the dual-axis motor 20 is bolted to the top of the first stepping pedal 4.

[0021] See also Figure 2 The front and rear sides of the left side of the external contact member 2 are provided with a snap-in groove 12, the front and rear sides of the external contact member 2 are provided with a round hole 11, and the front and rear sides of the right side of the base plate 1 are welded with a snap-in block 10.

[0022] See also Figure 3, the output ends of the front and rear sides of the dual-axis motor 20 are welded with threaded rods 19, and the surface of the threaded rod 19 is threadedly sleeved with a threaded barrel 18. A transmission connecting plate 3 is welded on the side of the threaded barrel 18 away from the threaded rod 19. By setting the transmission connecting plate 3, the plug-in rod 17 can be transmitted during the movement of the threaded barrel 18, so that it is convenient to insert it into the inner cavity of the clamping block 10 and the circular hole 11 to position it. The plug-in rods 17 are welded on the opposite sides of the two transmission connecting plates 3.

[0023] See also Figure 2 The surface sliding sleeve of the threaded cylinder 18 is provided with a limit sleeve 21. By setting the limit sleeve 21, the threaded cylinder 18 can be limited during its movement, thereby preventing it from rotating with the threaded rod 19. The top of the limit sleeve 21 is welded to the bottom of the first pedal 4.

[0024] See also Figure 2 Both sides of the bottom of the inner cavity of the shell 8 are hot-melt connected with rubber spring columns 13, the top of the rubber spring column 13 is hot-melt connected with a sliding plate 14, and the top of the sliding plate 14 is welded with a contact bracket 16.

[0025] See also Figure 2 Both sides of the sliding plate 14 pass through the outside of the shell 8, and guide rods 15 are welded on the top of the bottom plate 1 and on both sides of the shell 8. The top of the guide rod 15 passes through the top of the sliding plate 14 and is welded with a limit block. By setting the limit block, the sliding plate 14 can be limited to prevent it from falling off the surface of the guide rod 15. Sliding holes used in conjunction with the sliding plate 14 are opened on both sides of the shell 8, and the surface of the sliding plate 14 is slidably connected to the connection between the inner wall of the sliding hole and the surface of the sliding plate 14.

[0026] During use, when installation is required, the user first pushes the clamping block 10 horizontally into the inner cavity of the clamping groove 12, and then starts the dual-axis motor 20 through the external controller. The output ends on both sides of the dual-axis motor 20 drive the threaded cylinder 18 to move through the threaded rod 19, thereby driving the plug-in rod 17 to move through the transmission connecting plate 3, so that the plug-in rod 17 is stuck in the circular hole 11 and the inner cavity of the clamping block 10 to position it, thereby completing the clamping installation. When the user completes the height adjustment of the equipment through the hydraulic cylinder telescopic frame 5, the servo motor 7 can be started through the external controller. The output end of the servo motor 7 drives the second pedal 9 to adjust the angle, so that the bottom of the second pedal 9 contacts the top of the contact bracket 16, and then the contact bracket 16 is pressed by the second pedal 9. The rubber spring column 13 is squeezed, and the second pedal 9 is elastically supported under the elastic force generated by the recovery of the deformation of the rubber spring column 13, thereby providing better support stability.

[0027] In summary, this quickly installed construction site safety passage solves the problems of poor support effect and complicated installation steps by providing a circular hole 11, a snap-in groove 12, a rubber spring column 13, a sliding plate 14, a guide rod 15, a contact bracket 16 and a plug-in rod 17.
