If the number of ladder parts 100 is large and the length of the folding ladder module is long, the support part 200 can support the ladder part 100 to avoid brittle bending or deformation. The setting of the slat 300 can improve the grip of the ladder part 100 and the upper working surface, and the setting of the anti-skid part can improve the anti-skid performance of the ladder part 100 and the lower working surface, effectively improve the friction between the ladder part 100 and the ground, and avoid the ladder part 100 from slipping and displacement. The overall structure of the present application is complete and compact, which improves the stability, reliability and safety of climbing work, can be used in different working conditions and environments, and has a wide range of applications.

[0052] In a possible implementation, the ladder portion 100 includes: two side beams 110 and two or more tooth plates 120; the planes of the two side beams 110 are parallel to each other; the two or more tooth plates 120 are arranged between the two side beams 110; the two or more tooth plates 120 are arranged in sequence along the length direction of the side beams 110. It should be noted that the two side beams 110 serve as a skeleton structure to support and install the tooth plates 120, and the two or more tooth plates 120 are suitable for clamping the crawler robot during climbing to prevent the crawler robot from detaching, so as to enable the crawler robot to climb along the length direction of the side beams 110.

[0053] In a possible implementation, two ladder parts 100 are provided, the anti-slip part is fixedly connected to the end of one of the ladder parts 100, and the strap 300 is fixedly connected to the end of the other ladder part 100; the two ladder parts 100 are foldably connected via the folding part.

[0054] As shown in the figure, the main body of the side beam 110 is a rectangular plate-like structure, and an anti-skid foot 111 is provided at one end. The main body of the anti-skid foot 111 is a trapezoidal structure. The bottom surface of the trapezoidal structure is integrally arranged with the end surface of the side beam 110. The two side beams 110 are arranged opposite to each other and parallel to each other, and the distance between the two side beams 110 is the same as the length of the tooth plate 120.

Figure 6 As shown, the main body of the anti-skid plate 400 is a trapezoidal plate structure, which is fixed to the anti-skid foot 111 of the side beam 110 by multiple screws. The top surface of the anti-skid plate 400 protrudes from the inclined surface of the anti-skid foot 111 and is a sawtooth structure, which can reduce the grip area and increase the friction coefficient. Compared with the flat anti-skid plate, the setting of the sawtooth structure effectively improves the anti-skid performance. The two anti-skid plates 400 are respectively set on the outer side of the two side beams 110.

[0056] In a possible implementation, the strap 300 is fixed in the middle of the two side beams 110, and one end of the strap 300 protrudes out of the two side beams 110.

The other side beam 110 is inserted into the other folding splint 500 in the same way. The two folding splints 500 are arranged closely to each other, and the hinge part 510 of one folding splint 500 is inserted into the inner side of the hinge part 510 of the other folding splint 500 to achieve the correspondence of the hinge holes of the two hinge parts 510, and the rotating shaft 600 penetrates into the hinge holes of the two folding splints 500 to achieve the foldable connection of the two folding splints 500, thereby achieving the foldable connection of the two side beams 110.

When all the ladder parts 100 are folded, the support rod rotates and is set close to more than two tooth plates 120, and the support rod is smoothly clamped into the clamp 140 to achieve a close connection between the support rod and the ladder part 100 after folding, reducing the occupied area; when all the ladder parts 100 are unfolded, the support rod rotates and moves away from more than two tooth plates 120, and is supported on the ground to play a role of support and reinforcement.
