[0023] like Figure 1-4 As shown, a new type of platform lifting insulated ladder comprises a supporting main ladder 1, two universal wheels 6 are installed at the lower front end of the supporting main ladder 1, two anti-slip support pads 7 are installed at the lower end of the supporting main ladder 1, an adjusting ladder 2 is movably installed at the rear end of the supporting main ladder 1, a No. 2 support frame 4 is fixedly installed at the lower rear end of the adjusting ladder 2, a No. 1 support frame 3 is fixedly installed at the upper rear end of the adjusting ladder 2, a number of ladder handrails 5 are fixedly installed between the left inner wall and the right inner wall of the supporting main ladder 1 and the adjusting ladder 2, two fixing frames 9 are fixedly installed at the upper rear end of the adjusting ladder 2, and the upper ends of the two fixing frames 9 are fixedly connected to the No. 1 support frame 3, two handrails are fixedly installed at the upper end of the adjusting ladder 2, and both handrails are provided with safety belt hooks 8.

[0024] A connecting shaft 20 is movably installed on the left inner wall and the right inner wall of the adjusting ladder 2, and a lifting card plate 21 is fixedly installed on the outer surface of the two connecting shafts 20. The lower ends of the two lifting card plates 21 are provided with handrail slots 22, and a pull rope 25 is commonly installed on the rear ends of the two lifting card plates 21. A fixing plate 23 is fixedly installed on the left inner wall and the right inner wall of the adjusting ladder 2, and a group of springs 24 are installed at the front ends of the two fixing plates 23. The front ends of the two groups of springs 24 are fixedly connected to the two lifting card plates 21 respectively, and two sliders 26 are fixedly installed at the front end of the adjusting ladder 2; the handrail slot 22 is consistent with the size of the ladder handrail 5 and the position corresponds up and down; the adjusting ladder 2 is movably installed on the rear end of the supporting main ladder 1 through the slider 26. When the adjusting ladder 2 is moved to a suitable height, the handrail slot 22 on the lifting card plate 21 will be clamped on the ladder handrail 5 to limit the adjusting ladder 2.
