[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] Reference Figure 1-Figure 4The fire hook ladder comprises a hook ladder body 1, which is made of aluminum alloy. Two kinds of wooden ladder steps are arranged on the inner side of the hook ladder body 1. The two kinds of wooden ladder steps are twelve in total, including ladder step 1 2 and ladder step 2 3. Counting upward from the lower end of the hook ladder body 1, the ladder step 1 2 is distributed in the first section, the fourth section, the seventh section, the eleventh section and the twelfth section. Both ends of the ladder step 1 2 and the ladder step 2 3 are fixedly sleeved with titanium fixing rings 4, and the fixing rings 4 are welded to the inner wall of the hook ladder body 1. The ladder steps 1 2 and 2 3 are fixed on the hook ladder body 1, a steel wire rod is inserted inside the ladder step 1 2, and steel screws 5 are fixedly connected between the two ends of the steel wire rod and the hook ladder body 1, and the steel wire rod is used to improve the connection strength between the ladder step 1 2 and the hook ladder body 1. The outer walls of the two wooden ladder steps located at the upper end of the hook ladder body 1 are respectively fixedly sleeved with a titanium fixed sleeve 1 6 and a titanium fixed sleeve 2 7, and a ladder hook is fixed on the fixed sleeve 1 6 and the fixed sleeve 2 7.

[0020] The ladder hook includes a titanium connecting plate 18 and a connecting plate 29, the connecting plate 18 is fixedly sleeved on the fixing sleeve 16 and the fixing sleeve 27, the connecting plate 18 and the connecting plate 29 are integrally formed, and the connecting plate 18 is welded to the fixing sleeve 16 and the fixing sleeve 27, the connecting plate 29 is fixedly connected to the upper end of the connecting plate 18 and is perpendicular to the connecting plate 18, and a plurality of uniformly arranged saw teeth 10 are fixed on the lower side wall of the connecting plate 29, the tooth tips of the saw teeth 10 face the hook ladder body 1, and the angle of the saw teeth 10 is Less than 90 degrees, a titanium right-angle reinforcement rib 11 is attached at the angle between the connecting plate 1 8 and the connecting plate 2 9, and titanium strip reinforcement ribs 12 are attached on both sides of the connecting plate 2 9.
