[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0016] See also Figures 1 to 3 In an embodiment of the utility model, a tower crane ladder includes a standard section 1, which is equipped with a protective ring 2 through a connecting mechanism. There are multiple protective rings 2, and the multiple protective rings 2 are equidistantly distributed in the up and down directions. The multiple protective rings 2 are fixedly connected by welding plates 3. There are multiple welding plates 3, and the multiple welding plates 3 are equidistantly distributed in the circumferential direction of the protective rings 2. Two adjacent protective rings 2 are connected up and down through a docking mechanism.

[0017] In this embodiment: first, before the standard section 1 is docked, the protective ring 2 is installed on the inner side of the standard section 1 through the connecting mechanism. Then, when the standard section 1 is docked, the upper standard section 1 drives the protective ring 2 to dock with the protective ring 2 on the inner side of the lower standard section 1 through the docking mechanism. After docking, the upper and lower ends of the two sets of protective rings 2 are effectively docked.

[0018] Please refer to Figure 1 and Figure 2The connecting mechanism includes a protruding plate 5 integrally formed at the top and bottom ends of the outer periphery of the welding plate 3. A fixing plate 6 is integrally formed at the end of the protruding plate 5 away from the protective ring 2. The fixing plate 6 is fixedly connected to the cross bar portion of the standard section 1 by bolts and nuts.

[0019] In this embodiment: first, eight fixing plates 6 are attached to the inner side of the crossbar of the standard section 1, and the fixing plates 6 are fixed to the crossbar of the standard section 1 using bolts and nuts. At this time, the protective ring 2 is located at the inner center position of the standard section 1. In this way, a set of protective rings 2 can be fixedly installed on the inner side of the standard section 1.

[0020] Please refer to Figure 1 and Figure 3 The docking mechanism includes an upper docking clamp 9 fixedly connected to the top of the uppermost protective ring 2 and a lower docking clamp 11 fixedly connected to the bottom of the lowermost protective ring 2. Both the upper docking clamp 9 and the lower docking clamp 11 are provided with docking grooves 10, and the upper docking clamp 9 and the lower docking clamp 11 are staggered in the upper and lower positions.

[0021] In this embodiment: when the upper standard section 1 is docked with the lower standard section 1, the upper protective ring 2 drives the lower docking clamp 11 at its bottom end to dock with the lower protective ring 2, and the upper docking clamp 9 at the top of the lower protective ring 2 can be docked with the upper protective ring 2. At this time, the docking groove 10 is stuck on the outside of the protective ring 2 to ensure that the upper and lower sets of protective rings 2 are aligned in the upper and lower positions.

[0022] Please refer to Figure 2 The inner periphery of the top and bottom protective rings 2 are welded with fixing ears 8, and the inner walls of the fixing ears 8 aligned in the up and down directions are fixedly connected with vertical rods 7, and multiple equidistantly distributed cross bars 4 are vertically welded between the two vertical rods 7.

[0023] In this embodiment, the vertical rod 7 and the horizontal rod 4 form a climbing ladder, which allows workers to climb up along the standard section 1.
