[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0023] Please see Figure 1-5 This utility model discloses a protective railing assembly for tower cranes, including a tower crane base 1 and a reinforcement platform 2. The tower crane base 1 is located inside the reinforcement platform 2. An installation notch is provided at the center of the reinforcement platform 2. The tower crane base 1 contacts the foundation through the installation notch. A protective railing 3 is provided around the reinforcement platform 2. A single-wing fall arrestor structure 4 and a double-wing fall arrestor structure 5 are respectively provided at the top of the protective railing 3.

[0024] The protective fence 3 includes a support frame 301, a protective baffle 302 is movably attached to the inner side of the support frame 301, and a connecting side post 303 is welded to the outer side of the support frame 301. Two adjacent support frames 301 are spliced ​​together by the connecting side post 303.

[0025] The single-wing fall arrestor structure 4 includes a connecting frame 401, a splicing guard plate 402 is fixedly inserted into the inner side of the connecting frame 401, a connecting brace 403 is fixedly installed on the outer side of the connecting frame 401, and the other end of the connecting brace 403 is fixedly connected to the connecting crossbar 404.

[0026] The surface of the splicing guard plate 402 is provided with a wear-resistant layer, which can increase the hardness of the surface of the splicing guard plate 402, thereby improving the wear resistance of the splicing guard plate 402, preventing the splicing guard plate 402 from being worn during use, and thus extending the service life of the splicing guard plate 402.

[0027] The dual-wing fall arrestor structure 5 consists of a splicing device 501 and two single-wing fall arrestor structures 4, with the two single-wing fall arrestor structures 4 arranged opposite each other on both sides of the splicing device 501.

[0028] The splicing device 501 includes two splicing plates 502, which are connected to each other by a connecting rod 503. A socket block 504 is movably inserted into the side end of the splicing plate 502, and a plug 505 is fixedly installed at the end of the socket block 504. The surface of the socket block 504 is provided with a plug-in port 506.

[0029] By setting up a protective fence 3, a single-wing fall arrestor 4, and a double-wing fall arrestor 5, the protective fence 3 can form a protective enclosure around the tower crane base 1. This not only effectively prevents personnel from accidentally entering the tower crane's working area but also protects the safety of the tower crane itself. In conjunction with the single-wing fall arrestor 4 and the double-wing fall arrestor 5, it can block objects falling from the tower crane, thereby protecting the safety of workers around the protective fence 3 and further improving the safety protection effect of the protective fence assembly.

[0030] Specifically, the surface of the protective baffle 302 is provided with reflective strips, which face outwards from the support frame 301.

[0031] In this implementation plan, by installing reflective strips, the presence of the protective fence 3 can be noticed by surrounding personnel at night or in low-light environments, further improving the safety protection effect. The reflective strips are made of highly reflective material, which can reflect bright light under illumination, thereby attracting the attention of personnel and preventing them from accidentally entering the tower crane working area, reducing the occurrence of safety accidents.

[0032] Specifically, the splicing guard plates 402 on the inner side of the connecting frame 401 are fitted together, and the fitted splicing guard plates 402 form a wave-like undulation on the inner side of the connecting frame 401.

[0033] In this implementation scheme, by setting the undulating splicing guard plate 402, the surface area of ​​the inner side of the connecting frame 401 can be increased, thereby improving the overall strength of the single-wing fall arrestor structure 4. Simultaneously, the undulating design also increases the friction between the object and the splicing guard plate 402, making it easier to stop falling objects and further improving the safety protection effect. Furthermore, the undulating design also acts as a buffer, reducing the impact force on the single-wing fall arrestor structure 4 when an object impacts the splicing guard plate 402, thus extending its service life.

[0034] Specifically, the side of the connecting crossbar 404 away from the connecting diagonal brace 403 is rotatably connected to the splicing plate 502 and the support frame 301 respectively via the hinge 405.

[0035] In this embodiment, by setting the hinge 405, the rotatable connection between the connecting crossbar 404 and the splicing plate 502 and the support frame 301 can be realized, thereby facilitating the installation and disassembly of the single-wing fall arrest structure 4 and the double-wing fall arrest structure 5 and improving the installation efficiency.

[0036] When in use, first connect the reinforcement platform 2 to the ground, then connect the tower crane base 1 to the notch in the center of the reinforcement platform 2 to make the tower crane base 1 contact the ground, and then fix the tower crane base 1 to the ground with bolts and other reinforcement components.

[0037] At this time, the protective fence 3 is installed around the tower crane base 1, so that the protective fence 3 can surround the outside of the tower crane base 1. The adjacent support frame 301 is spliced ​​by connecting the side column 303 to form a complete protective fence 3.

[0038] Then, the installation of the single-wing fall arrestor structure 4 and the double-wing fall arrestor structure 5 begins. First, the splicing guard plate 402 is inserted into the inner side of the connecting frame 401, and the splicing guard plate 402 is connected to the connecting frame 401 by a fixed plug-in method. Then, the connecting diagonal brace 403 is fixed to the outer side of the connecting frame 401. Finally, the connecting crossbar 404 is fixedly connected to the other end of the connecting diagonal brace 403 to form a complete single-wing fall arrestor structure 4.

[0039] Then, the two single-wing fall arrest structures 4 are placed opposite each other on both sides of the splicing device 501, the splicing plate 502 is connected to the single-wing fall arrest structure 4, and the connecting rod 503 is passed through the two splicing plates 502 to fix the two splicing plates 502 together to form a complete double-wing fall arrest structure 5.

[0040] Finally, the single-wing fall arrestor 4 and the double-wing fall arrestor 5 are installed on the top of the protective fence 3 to complete the installation of the entire tower crane protective fence assembly.

[0041] After installation, the tower crane base 1 is surrounded by a protective fence 3 to prevent personnel from accidentally entering the tower crane working area. At the same time, the single-wing fall arrestor 4 and the double-wing fall arrestor 5 are used to block falling objects, protect the safety of surrounding workers, and improve the overall safety protection effect.

[0042] In summary, this tower crane safety railing assembly, by setting up a safety railing 3, a single-wing fall arrestor 4, and a double-wing fall arrestor 5, can effectively prevent personnel from accidentally entering the tower crane working area and protect the safety of the tower crane itself. In addition, the single-wing fall arrestor 4 and the double-wing fall arrestor 5 can block objects falling from the tower crane, thereby protecting the safety of workers around the safety railing 3, and further improving the safety protection effect of the safety railing assembly.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
