Preferably, a reinforcing rod is fixedly mounted on the horizontal sliding frame. The strength is improved.
In conclusion, the top is taken as the first step, the first step is fixedly provided with and fixes the step plates, the rest steps, namely the movable step plates, the diagonal draw bars and the step plate frame are movably connected, the movable step plates and the diagonal draw bars can rotate along with the step plates in the rotation process of the step plate frame, and the steps are always parallel to the ground; step board, oblique pull rod, ladder rack form the parallelogram structure, and when the contained angle was 180 between ladder rack and the horizontal sliding rack, oblique pull rod and step board can be hidden completely and form wholly at ladder rack inside, are more convenient for accomodate.
Specifically, the method has the following beneficial effects:
1. the boarding ladder has stable and reliable structure and convenient use;
2. the movable step plate can be linked with the ladder plate frame to overturn;
3. no matter how the height of the ground is changed, the steps can be always parallel to the ground;
4. the bottom of the sole is provided with the angle-adjustable sole, so that the contact area of the sole and the uneven ground is ensured to a greater extent, and the side slip is prevented;
5. the step plates, the diagonal draw bars and the ladder plate frames form a parallelogram structure, and when the included angle between the ladder plate frames and the horizontal sliding frame is 180 degrees, the diagonal draw bars and the antiskid steps can be completely hidden in the ladder plate frames to form a whole;
6. the boarding ladder is provided with a safety lock pin at a specific position when being used and stored, so that the boarding ladder is prevented from shaking;
7. the upper ladder is accommodated and rolled into the slide rail through a bearing and is fixed through a safety lock pin;
8. the safety handrail is arranged, and can be detached when not in use, so that the safety of boarding personnel is ensured.
