[0025] 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.

[0026] Embodiment 1

[0027] Reference Figure 1-4 A high ladder comprises: a ladder body 1, six mounting posts 4 are welded to one side of the ladder body 1, a frame 5 is welded to one side of the six mounting posts 4, a mounting plate 6 is slidably connected to the inner wall of one side of the frame 5 for facilitating the installation of the ladder body 1, and a mounting hole 9 is opened on the mounting plate 6.

[0028] At the same time, the ladder is also provided with an adjustment mechanism, which is arranged on the six frames 5 and is mainly used to adjust the mounting plate 6 so that the mounting hole 9 is aligned with the reserved hole on the sludge thickening tank, thereby facilitating installation.

[0029] The specific structure of the adjustment mechanism is as follows: it includes six threaded rods 7 and six knobs 8. The six threaded rods 7 are used to adjust the six mounting plates 6, and the six knobs 8 facilitate the rotation of the threaded rods 7. A threaded hole is provided on one side of each frame 5, and the threaded rods 7 are threadedly connected to these threaded holes. In this way, when the knob 8 is rotated, the threaded rod 7 will perform a lifting movement, one end of the threaded rod 7 is rotatably connected to one side of the mounting plate 6, and one side of the knob 8 is fixedly connected to one end of the threaded rod 7.

[0030] Embodiment 2

[0031] refer to Figure 1-4 , improved on the basis of embodiment 1, an efficient modular large and medium-sized steel ladder is used in the field of ladders. On the ladder body 1, a plurality of convex strips 2 are fixedly arranged. These convex strips 2 are mainly used to increase the friction between the hands and feet of the personnel and the ladder body 1, thereby playing an anti-slip role. These convex strips 2 and the ladder body 1 are an integral structure and are directly formed during manufacturing without the need for additional installation, which greatly improves the manufacturing efficiency.

[0032] In addition, in order to improve the stability of the mounting plate 6, a T-shaped slide groove 10 is opened on the inner wall of one side of the frame 5. The inner wall of the T-shaped slide groove 10 is slidably connected with a T-shaped slider, and one end of the T-shaped slider is welded to one side of the mounting plate 6. When the mounting plate 6 slides in the frame 5, the T-shaped slider will slide in the T-shaped slide groove 10, thereby playing a guiding and stabilizing role.

[0033] In order to facilitate personnel to pay attention to some safety matters when using the ladder, a warning sign 3 is welded on one side of the ladder body 1. Some safety tips or precautions can be marked on the warning sign 3 to remind personnel to pay attention to safety when using the ladder.

[0034] Finally, in order to increase the friction of the person's hand when turning the knob 8, anti-skid grooves are provided on the knob 8. These anti-skid grooves can increase the friction between the person's hand and the knob 8, making the knob 8 easier to turn.

[0035] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
