[0021] Among them, the same reference numerals in the drawings all refer to the same components.

[0022] Embodiment 1

[0023] Referring to Figures 1-3 , an embodiment provided by the present utility model: an anti-falling climbing ladder, which includes a rigid guide rail 1 and an anti-falling device 2. The rigid guide rail 1 is provided in multiple sections and is connected and fixed through a mortise and tenon structure. Tread bars 3 are provided on both surfaces of the rigid guide rail 1. Dovetail groove interfaces 4 are provided on both end surfaces of the rigid guide rail 1. Double-sided connecting plates 5 are provided on both surfaces of the dovetail groove interface 4. Connecting bolts 6 are provided on the inner side of one surface of the double-sided connecting plate 5. A guide rail clamping plate 7 is provided at the top of the double-sided connecting plate 5. An anti-falling device 2 is provided on one surface of the rigid guide rail 1. An O-ring buckle 8 is provided on one end surface of the anti-falling device 2.

[0024] The rigid guide rail 1 and the tread bar 3 are both connected by threads. The tread bar 3 is provided in multiple groups and is arranged in sequence on both surfaces of the rigid guide rail 1. The rigid guide rail 1 is provided in multiple sections for assembly. The dovetail groove interfaces 4 at both ends of the rigid guide rail 1 are respectively provided as concave openings and convex openings.

[0025] The rigid guide rail 1 and the double-sided connecting plate 5 are connected and fixed by connecting bolts 6 at the dovetail groove interfaces 4 at both ends of the two ends of the rigid guide rail 1. The double-sided connecting plate 5 is a four-hole connecting plate, and connecting bolts 6 are provided in all four holes. The connecting bolt 6 includes a screw rod and a nut.

[0026] The rigid guide rail 1 and the guide rail clamping plate 7 are connected and fixed by bolts. Two guide rail clamping plates 7 are provided as a group and are sequentially arranged at both ends of one surface of each end of the rigid guide rail 1. The rigid guide rail 1 and the anti-falling device 2 are assembled by splicing, and the anti-falling device 2 and the O-ring buckle 8 are fixedly connected.

[0027] Specifically, its structure consists of a rigid guide rail 1, a fall arrester 2, a tread bar 3, a dovetail groove interface 4, a double-sided connecting plate 5, a connecting bolt 6, a guide rail clamping plate 7, and an O-ring buckle 8 to form a fall-proof climbing ladder. The fall-proof climbing ladder can effectively protect the safety of high-altitude workers and improve work efficiency at the same time. The overall rigid guide rail 1 made of I-beams is assembled and combined section by section. The dovetail groove interface is adopted to form a mortise and tenon structure connection and fixation, making the precision higher and the strength better. The two sides of the butt joint of two sections of the rigid guide rail 1 are clamped by the double-sided connecting plate 5 and fixed by inserting the connecting bolt 6 and tightening with a nut, so that the assembly of the rigid guide rail 1 is not easy to shift or misalign, ensuring the strength. Tread bars 3 are distributed at intervals on the rigid guide rail 1, facilitating workers to climb the tower. The front wing plate of the rigid guide rail 1 is smooth and flat, and the fall arrester 2 can slide up and down at the front wing of the rigid guide rail 1. The rigid guide rail 1 is clamped by the guide rail clamping plate 7 to make it more stable. The fall arrester 2 is quickly connected to the safety belt through the O-ring buckle 8, effectively ensuring the risk of workers falling. When the fall arrester 2 moves upward, it can slide smoothly. When descending, due to the rapid change in speed, the fall arrester 2 will lock due to the speed difference and stay on the rigid guide rail 1, achieving the functions of preventing falling and automatic locking, thus ensuring the safety of the personnel climbing the tower, enabling the fall-proof climbing ladder to effectively save work space, reduce the risk of high-altitude falling, improve work efficiency and overall practicality.
