The right side of the rear of the transmission mechanism 6 is fixedly connected to the left side of the lower part of the lifting mechanism 7. The right side of the lower part of the lifting mechanism 7 is fixedly connected to a matching mechanism 9, which can cooperate with the octagonal column 101 to clamp and fix the bearing base 71. The right part of the upper end of the outer surface of the base plate 1 is fixedly connected to a hydraulic cylinder 8, and the output end of the piston rod of the hydraulic cylinder 8 is fixedly connected to a locking mechanism 10, which can lock the docking height of the platform body 31.

[0023] In order to achieve the purpose of guiding the lifting of the carrying mechanism 3, refer to Figure 2 The guide mechanism 2 includes a fixed shell 21, a guide column 22 is slidably connected to the inner cavity of the fixed shell 21, and the lower end of the outer surface of the fixed shell 21 is fixedly connected to the upper end of the outer surface of the bottom plate 1.

[0024] When the platform body 31 is being raised and lowered, the four guide columns 22 fixedly connected to the four corners of the lower end of the platform body 31 will slide up and down along the corresponding inner cavities of the fixed shell 21, thereby guiding the movement trajectory of the platform body 31 during the raising and lowering adjustment process.

[0025] In order to achieve the purpose of lifting and lowering staff and mechanical equipment, refer to Figure 2 The supporting mechanism 3 includes a platform body 31, and a guardrail 32 is fixedly connected to the upper end of the outer surface of the platform body 31, which can protect the staff standing in the inner cavity of the platform body 31, and the lower end of the outer surface of the platform body 31 is fixedly connected to the upper ends of the outer surfaces of the four guide columns 22 respectively.

[0026] In order to achieve the purpose of lifting and lowering the platform body 31, refer to Figure 3 The lifting mechanism 7 includes a bearing base 71, and a rotating support member 72 is fixedly connected to the middle of the bearing base 71, which can realize the lifting and adjusting effect of pushing the platform body 31 upward or pulling it downward during the rotation process. The upper part of the rotating support member 72 is fixedly connected to the middle part of the lower end of the outer surface of the platform body 31.

[0027] In order to achieve the purpose of driving the rotating support member 72 to rotate, refer to Figure 3 The transmission mechanism 6 includes a rack 61, the upper part of the outer surface of the rack 61 is meshed with a gear 62, the middle part of the gear 62 is fixedly connected to a transmission shaft 63, the right end of the outer surface of the transmission shaft 63 is fixedly connected to the left end of the outer surface of the bearing base 71, and the lower part of the rack 61 is slidably connected to the inner cavity of the slide groove 11.

[0028] When the cylinder 5 starts to drive, the piston rod output end of the cylinder 5 will push the rack 61 to slide in the inner cavity of the slide groove 11. At this time, the gear 62 will engage with the upper outer surface of the rack 61 and drive the transmission shaft 63 to rotate, thereby driving the rotating support 72 to start rotating through the transmission of the bearing base 71.

[0029] In order to achieve the purpose of clamping and fixing the bearing base 71 in cooperation with the octagonal column 101, refer to Figure 4 The matching mechanism 9 includes a connecting shaft 91, and a clamping sleeve 92 is fixedly connected to the right end of the outer surface of the connecting shaft 91, which can realize the function of clamping and fixing the rotating support member 72 by matching with the octagonal column 101.

[0031] When the platform body 31 needs to be docked, first stop the cylinder 5 from pushing the rack 61, then the rotating support 72 will stop rotating, and then drive the hydraulic cylinder 8 so that its piston rod pushes the octagonal column 101 into the inner cavity of the octagonal clamping groove 93, thereby completely blocking and locking the rotation of the rotating support 72.

At this time, the piston rod output end of the cylinder 5 will push the rack 61 to start sliding, and the gear 62 will be meshed with the rack 61 to drive the transmission shaft 63 to rotate, thereby driving the rotating support 72 to rotate and support and raise and lower the platform body 31.
