The first first assembly frame 51 is fixedly connected to the end of the cantilever section 41, and then multiple first assembly frames 51 are sequentially fixedly connected end-to-end until the required height is reached. Finally, the second assembly frame 52 is fixedly connected to the last first assembly frame 51 and the working platform 6. The counterweight device 7 is installed on the side of the seat 1 away from the working platform 6, according to the load-bearing capacity of the working platform 6 and the operational requirements, to ensure the stability of the work vehicle during construction.

[0018] Specifically: The first assembly frame 51 includes four vertically arranged columns 511, adjacent columns 511 are fixedly connected by connecting rods 512 to form a rectangular frame. The upper end of each column 511 is provided with a first male head 513, and the lower end of each column 511 is provided with a first female head 514. The first male head 513 of each column 511 is fixedly connected to the first female head 514 of another column 511 located above the column 511 or the second female head 411 of the protruding section 41 by bolts or pins. The first female head 514 of each column 511 is fixedly connected to the first male head 513 of another column 511 located below the column 511 or the second male head 525 of the second assembly frame 52 by bolts or pins. The second assembly frame 52 includes four vertically arranged vertical rods 521, adjacent vertical rods 521 are connected by connecting rods 512 to form a rectangular frame. A rectangular frame is formed by multiple horizontal bars 522. The upper end of the vertical bar 521 is provided with a second male head (525) corresponding to the first female head (514) of the column 511, and the lower end of the vertical bar 521 is provided with a third female head (61) corresponding to the third male head (61) of the working platform 6. The third female head (524) of the vertical bar 521 and the third male head (61) of the working platform 6 are fixedly connected by bolts or pins. The length of the vertical bar 521 is greater than the length of the column 511. It also includes a diagonal bar 523, the two ends of which are fixedly connected to the two vertical bars 521 respectively. In this embodiment, during the assembly process, multiple first assembly frames 51 are firstly connected end to end by first male heads (513) and first female heads (514) with bolts or pins to form a frame structure of a certain height.

The weight of the counterweight blocks 72 can be flexibly adjusted according to actual construction needs. By increasing or decreasing the number of counterweight blocks 72, the overall center of gravity of the work vehicle can be changed, ensuring the stability of the work vehicle under different working conditions.
