The boot body columns comprise a fixed column 3, a boot middle column 2, and a boot column column core 1, wherein the fixed column 3 is fixedly mounted on the top of the base frame 7, the boot middle column 2 is located on the inner side of the fixed column 3 and is slidably connected to the fixed column 3, and the boot column core 1 is located on the inner side of the boot middle column 2 and is slidably connected to the boot middle column 2.

[0021] It should be noted that a lifting platform 11 is arranged above the base frame 7, and each of the four corners of the top of the base frame 7 has a boot body column, which is used to move the lifting platform 11 up and down. The boot body column is composed of a fixed column 3, a boot middle column 2 and a boot column core 1. The fixed column 3 is fixedly installed on the top of the base frame 7, the boot middle column 2 is located on the inner side of the fixed column 3 and is slidably connected thereto, and the boot column core 1 is located on the inner side of the boot middle column 2 and is slidably connected thereto. The up and down movement of the boot middle column 2 and the boot column core 1 is achieved through the sliding connection of the boot body column. When the height of the lifting platform 11 needs to be adjusted, the boot middle column 2 is moved up and down by operating the corresponding driving member, thereby driving the boot column core 1 and the entire lifting platform 11 to rise or fall together.

[0022] In the embodiments of the present invention, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4The bottom of the fixed column 3 extends into the underframe 7 and is connected to the fixed column lower steering wheel 5, the top of the fixed column 3 is equipped with a fixed column plate chain upper steering wheel 10, the top of the fixed column 3 close to the middle column 2 of the sleeve boot is connected to the middle column plate chain fixed end 14, the top of the middle column 2 of the sleeve boot is equipped with an middle column plate chain steering wheel 9, the bottom of the middle column 2 of the sleeve boot close to the fixed column 3 is connected to the fixed column plate chain lifting end 15, the top of the middle column 2 of the sleeve boot close to the sleeve boot column column core 1 is equipped with a column core plate chain fixed end 12, the bottom of the sleeve boot column core 1 close to the sleeve boot middle column 2 is connected to the middle column plate chain lifting end 13, the top of the sleeve boot column core 1 is equipped with a column core plate chain rotating end 13. Steering wheel 8, a hydraulic cylinder 6 is installed in the base frame 7, the output end of the hydraulic cylinder 6 is connected to a fixed column plate chain 18, the end of the fixed column plate chain 18 away from the hydraulic cylinder 6 passes through the outer side of the steering wheel 5 under the fixed column and the steering wheel 10 on the fixed column plate chain and is connected to the fixed column plate chain lifting end 15, the intermediate column plate chain fixed end 14 is connected to the intermediate column plate chain 17, the end of the intermediate column plate chain 17 away from the intermediate column plate chain fixed end 14 passes through the outer side of the intermediate column plate chain steering wheel 9 and is connected to the intermediate column plate chain lifting end 13, the column core plate chain fixed end 12 is connected to the column core plate chain 16, the end of the column core plate chain 16 away from the column core plate chain fixed end 12 passes through the outer side of the column core plate chain steering wheel 8 and is connected to the lifting platform 11.

[0023] It should be noted that the steering wheel 5 under the fixed column, the steering wheel 10 on the fixed column plate chain, the steering wheel 9 of the intermediate column plate chain and the steering wheel 8 of the column core plate chain are all used to guide the movement of the chain to ensure that the chain moves smoothly during the lifting process while reducing friction resistance. The fixed column plate chain 18, the intermediate column plate chain 17 and the column core plate chain 16 are interconnected with each other under the guidance of the steering wheel to form a closed loop link. When the hydraulic cylinder 6 applies force, the fixed column plate chain 18 connected to the output end of the hydraulic cylinder 6 begins to move, and then through the guidance of the steering wheel, the intermediate column plate chain 17 and the column core plate chain 16 also follow the movement, thereby driving the lifting platform 11 to move.

[0024] In the embodiments of the present invention, please refer to Figure 1 , Figure 2 and Figure 3 Equipment travel driving wheels 4 are installed at both ends of one side of the bottom of the chassis 7, and equipment travel steering wheels 19 are installed at both ends of the bottom of the chassis 7 away from the equipment travel driving wheels 4.

[0025] It should be noted that the equipment travel driving wheels 4 are installed at both ends of one side of the bottom of the chassis 7, and are used to provide power for the equipment to travel, and drive the entire equipment to move in the working area by rotating. The equipment travel steering wheels 19 are installed at both ends of the bottom of the chassis 7 away from the equipment travel driving wheels 4, and are used for steering control of the chassis 7, so that the direction of the chassis 7 changes when traveling, thereby improving maneuverability and operational flexibility.

[0026] The working principle of the movable lifting device provided by the utility model is as follows: when the output end of the hydraulic cylinder 6 is recovered, the fixed column plate chain 18 is pulled, and the other end of the fixed column plate chain 18 is connected to the fixed column plate chain lifting end 15, and the fixed column plate chain 18 passes through the fixed column lower steering wheel 5 and the fixed column plate chain upper steering wheel 10, so that the fixed column plate chain lifting end 15 moves upward, and at this time, the middle column 2 of the sleeve shoe moves upward, and one end of the middle column plate chain 17 is connected to the middle column plate chain fixed end 14, and the other end is connected to the middle column plate chain through the middle column plate chain steering wheel 9. The intermediate column plate chain lifting end 13 is connected. At this time, the intermediate column plate chain lifting end 13 will move upward due to the action of the intermediate column plate chain fixed end 14 and the intermediate column plate chain steering wheel 9. At this time, the column core 1 of the boot column also moves upward. One end of the column core plate chain 16 is connected to the fixed end 12 of the column core plate chain, and the other end is connected to the lifting platform 11 through the column core plate chain steering wheel 8. At this time, the lifting platform 11 will rise. Conversely, when the output end of the hydraulic cylinder 6 extends forward, the lifting platform 11 is driven down through the correlation between the plate chains at all levels and the column steering wheels.

[0027] The circuits and controls involved in the present invention are all prior art and will not be described in detail here.
