[0036] The technical scheme in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0037] Please refer to Figs. 1-2 The articulated dump truck soft ladder structure comprises an upper layer pedal 1, a movable pedal 2 and a side plate 3, wherein:

[0038] The left and right ends of the upper layer pedal 1 are fixed with fixed plates, and the two groups of fixed plates are respectively a left fixed plate 4 located on the left side and a right fixed plate 5 located on the right side, and mounting holes are formed in the fixed plates for being fixed on the vehicle;

[0039] The movable pedal 2 is located below the upper layer pedal 1 and is uniformly spaced from top to bottom with multiple groups;

[0040] The side plate 3 has two groups, and the two groups of side plates 3 are respectively hingedly connected with the left fixed plate 4 and the right fixed plate 5, and each group of side plates 3 is fixed with a canvas long strip plate 6 at the bottom, and the left and right ends of the movable pedal 2 are respectively fixed at the corresponding height of the two groups of canvas long strip plates 6, specifically:

[0041] The side plate 3 is an L-shaped plate, and the vertical section at the top of the side plate 3 is hingedly connected with the fixed plate on the corresponding side, and the horizontal section at the bottom of the side plate 3 is fixed with the top end of the canvas long strip plate 6 through at least two groups of fasteners 8, and the fastener 8 is a bolt and nut, that is, the bolt is screwed with a nut after penetrating through the end head of the side plate 3 and the canvas long strip plate 6;

[0042] The left and right ends of the movable pedal 2 are also fixed to the canvas strip 6 by at least two sets of fasteners 8;

[0043] Limiting blocks 7 are also fixed on both the left fixed plate 4 and the right fixed plate 5. The limiting blocks 7 are located on the rear side of the vertical section of the L-shaped plate. When the side plate 3 is in the vertical position, the rear wall of the vertical section of the L-shaped plate contacts the front wall of the limiting block 7. The limiting blocks 7 are used to prevent the side plate 3 from continuing to rotate backward. Thus, the rope ladder remains vertical when vehicles are getting on and off normally. Once it passes over large rocks or piles of dirt, the rope ladder will automatically rotate forward.

[0044] Please see Figs. 1-2 The articulated dump truck ladder structure has a canvas strip 6 that contacts the side plate 3 on one side at the height of the transverse section of the side plate 3, and contacts a set of pressure plates 9 on the other side.

The canvas strip 6 is clamped by the side plate 3 and the pressure plates 9.

[0045] The canvas strip 6 contacts the end plate of the movable pedal 2 on one side at the height of the movable pedal 2, and contacts another set of pressure plates 9 on the other side. The bolts in the fasteners 8 pass through the opposite end plate, the canvas strip 6 and the set of pressure plates 9 in sequence and are fixed and tightened with nuts. The end plate and pressure plates 9 are used to clamp the canvas strip 6. The setting of the pressure plates 9 can cooperate with the side plate 3 and the end plate to achieve flat clamping of the canvas strip 6 and prevent the canvas strip 6 from being excessively twisted. The fixing method of multiple sets of bolts and nuts not only has high connection strength, but also plays a certain role in preventing loosening.

[0046] Please see Fig. 1 The articulated dump truck ladder structure has holes on the surface of both the upper step 1 and the movable step 2, which reduces weight and facilitates the flow of rainwater.
