[0020] The following is combined with Figure 1-3 This application is described in further detail.

[0021] The embodiment of the present application discloses a safety protection device for building construction.

[0022] Reference Figure 1 and Figure 2The housing construction safety protection device comprises a platform bottom plate 1 horizontally arranged at the upper end of a lifting device, wherein the lifting device is such as a cross-scissor lift; in this embodiment, a guardrail assembly 2 is arranged at the upper edge of the platform bottom plate 1, and the guardrail assembly 2 comprises a plurality of cylindrical bottom rods 21 vertically welded to the upper surface of the platform bottom plate 1, the interior of the bottom rod 21 is hollow, and a matching movable rod 22 is penetrated in the bottom rod 21, and the movable rod 22 is slidably connected with the bottom rod 21; a limiting assembly 3 is arranged on the inner side wall of the guardrail assembly 2, and the limiting assembly 3 comprises a limiting rod 31 abutting against the side of the bottom rod 21, the limiting rod 31 is cylindrical and arranged along the arrangement direction of the bottom rod 21, and a cylindrical plug-in block 32 is vertically fixedly connected to the side of the limiting rod 31, and a plurality of positioning holes 23 are opened on the movable rod 22 and the bottom rod 21, and the plurality of positioning holes 23 are arranged equidistantly along the longitudinal direction, and the plug-in block 32 is penetrated in the positioning hole 23, so that the height of the movable rod 22 can be adjusted.

[0023] To prevent the limit assembly 3 from slipping during use, a lock buckle 4 is passed through the end of the plug-in block 32 away from the limit rod 31, and the lock buckle 4 is set in a "U" shape. The lock buckle 4 is passed through the plug-in block 32 and the side is abutted against the bottom rod 21. By passing the lock buckle 4 through the plug-in block 32, the limit assembly 3 will not fall off during use. By abutting the limit rod 31 on the inner side wall of the bottom rod 21 and the plug-in block 32 passing through the positioning hole 23, the height of the movable rod 22 can be fixed; a handrail rod 6 is welded to the upper end of the movable rod 22, the handrail rod 6 is cylindrical and a distance is left between two adjacent handrail rods 6, so as not to affect the adjustment of the height of the movable rod 22, and the handrail rod 6 is rectangular when viewed from above and the handrail rod 6 on one side is open.

[0024] Reference Figure 2 and Figure 3In order to facilitate the entry and exit of users, an access plate assembly 5 is provided at the opening of the handrail 6. A first rotating shaft 55 is fixedly connected to the side of the handrail 6, and a second rotating shaft 56 is fixedly connected to the upper end surface of the platform bottom plate 1. The access plate assembly 5 includes an upper access plate 51 rotatably connected to the handrail 6 through the first rotating shaft 55 and a lower access plate 52 rotatably connected to the platform bottom plate 1 through the second rotating shaft 56. The upper access plate 51 and the lower access plate 52 are vertically connected between the handrail 6 and the platform bottom plate 1. When the movable rod 22 is lowered to the lowest position, the upper access plate 51 abuts against the lower access plate 52; the upper access plate 51 and the lower access plate 52 are in contact with each other. A sliding rod 53 is passed through between the access plates 52. By setting the sliding rod 53, it is convenient for the user to synchronously open and close the upper access plate 51 and the lower access plate 52; a bolt assembly 54 is fixedly connected to the inner side of the lower access plate 52. The bolt assembly 54 is square in shape. The bolt assembly 54 includes a bolt block 541 fixedly connected to the inner side of the lower access plate 52 and a bolt handle 542 passed through the bolt block 541. A positioning groove is provided at a position opposite to the bolt handle 542 of the platform bottom plate 1. When a person enters the device of the present application, the bolt handle 542 needs to be clamped in the positioning groove to prevent the access plate assembly 5 from automatically opening when in use.

[0025] Reference Figure 1 In order to prevent the user from accidentally falling, a fixing rod 7 is welded on the side of the handrail rod 6. The fixing rod 7 is U-shaped when viewed from above. A safety rope buckle 8 is provided inside the fixing rod 7. A safety rope 9 is connected to the safety rope buckle 8. The user needs to wear the safety rope 9 when working.

[0026] Since the plate needs to be transported and placed in the device of the present application, a support block 11 is fixedly connected to the upper surface of the platform base plate 1. The support block 11 is "concave" in a top view and is provided with an opening, which faces the side of the guardrail assembly 2 where the access plate assembly 5 is located, so as to facilitate the placement of the plate in the support block 11. A blocking block 12 is fixedly connected to one side of the support block 11, and the blocking block 12 abuts against the lower end of the plate.

[0027] Instructions for use: Before use, the movable rod 22 is at the lowest position. At this time, the plate can be moved into the support block 11, and the blocking block 12 abuts against the lower end of the plate. Then the person enters the platform bottom plate 1, and then closes the access plate assembly 5 and lowers the bolt handle 542 of the bolt assembly 54 to close the access plate assembly 5. Then, adjust the movable rod 22 to a suitable height, use the limit rod 31 to align the positioning hole 23, and then insert the plug-in block 32 into the positioning hole 23, use the lock buckle 4 to fix the plug-in block 32, and finally put on the safety rope 9 to perform high-altitude operations.

[0028] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
