Detailed Implementation

[0021] The present invention will be further described below with reference to embodiments and accompanying drawings:

[0022] like Figures 2-6 As shown, a fully prefabricated assembled station with columns is available, suitable for prefabricated assembled stations with a single-column, double-span structure, such as... Figure 1 As shown, the prefabricated assembly station 80 has a rectangular structure formed by a top plate 81, side wall blocks 82 and a bottom plate 83. At the same time, a middle plate 84 is horizontally arranged in the middle of the rectangular structure and a central column 85 is vertically arranged. A central longitudinal beam 86 is arranged in the middle of the middle plate 84, a top longitudinal beam 87 is arranged in the middle of the top plate 81, and a bottom longitudinal beam 88 is arranged in the middle of the bottom plate 83.

[0023] The assembly trolley mainly consists of two bottom trolleys 10 and two top trolleys 20, spaced apart on either side of the central column. To enable movement of the bottom and top trolleys, a bottom traveling mechanism 30 is provided on the bottom trolley 10, which can move back and forth on a bottom rail 40 set on the bottom plate. A middle traveling mechanism 50 is provided at the bottom of the top trolley 20, which can move back and forth on a middle rail 60 set on the middle plate. To ensure stable support of the bottom and top trolleys at the assembly station, automatic anti-locking devices are installed between the bottom traveling mechanism and the bottom rail, and between the middle traveling mechanism and the middle rail. These automatic anti-locking devices are existing technology.

[0024] To facilitate the assembly of the middle plate, a middle plate trolley 70 is provided at the rear end of the top surface of each bottom trolley 10. The middle plate trolley 70 is equipped with a middle plate adjustment assembly for adjusting the position of the middle plate. Specifically, the middle plate trolley 70 includes a segmented crossbeam 71 located at the upper end of the bottom trolley 10. The middle plate adjustment assembly includes a horizontal movement mechanism 72, a vertical movement mechanism 73, and a lifting mechanism 74. The horizontal movement mechanism 72, the vertical movement mechanism 73, and the lifting mechanism 74 use hydraulic cylinders to achieve fine-tuning of the middle plate in the left-right, front-back, and up-down directions, that is, fine-tuning in the horizontal, vertical, and longitudinal directions.

[0025] Lateral adjustment components 11 for positioning the side panels and central columns are provided on both the left and right sides of the bottom trolley 10. The lateral adjustment components are lateral hydraulic cylinders, which are used for fine-tuning the side panels and central columns. At the same time, side wall tensioning frames 12 for installing the corresponding side panels are provided on the left and right sides of the two bottom trolleys 10. The side wall tensioning frames include a side wall tensioning hoisting mechanism for tensioning the hydrocephalus and a side wall tensioning operation platform for workers to operate. The side wall tensioning frames are used to ensure that the front side panel and the rear side panel can be tightly spliced ​​together.

[0026] The top trolley 20 includes a frame platform 21 and a top slab tensioning frame 22 set on the frame platform 21. The frame platform is segmented, so that the top trolley can adapt to stations of different widths. The top slab tensioning frame is used to achieve a tight connection between the previous top slab and the next top slab. In order to ensure the tensioning effect, several top slab tensioning frames are set at intervals on the two top slab trolleys. The top slab tensioning frame can provide a top slab operating platform for workers to operate and a top slab hoisting mechanism for tensioning the hydrocephalus.

[0027] The bottom trolley 10 includes two rows of support columns 14 spaced apart on the left and right. A main beam 15 is provided between the upper ends of each row of support columns 14, and a connecting beam 16 is provided between the two main beams 15. A longitudinal beam 17 is provided in the middle of each row of support columns 14. The connecting beam 16, the main beam 15, and the longitudinal beam 17 are all segmented, which makes the bottom trolley not only easy to dismantle the equipment later, but also suitable for different station widths.

[0028] To facilitate worker operation, a lifting platform 13 is provided at the front end of the top surface of the bottom trolley 10 for workers to install the top longitudinal beam. A ladder is provided on the bottom trolley 10 for workers to move from the bottom trolley to the top trolley. At the same time, walkways are provided on the bottom trolley and the top trolley, and guardrails are provided on the walkways.

[0029] When assembling prefabricated modular stations, the bottom slab, bottom longitudinal beam, bottom trolley, central column, central longitudinal beam, side wall block, middle slab, top slab trolley, bottom longitudinal beam, and top slab are installed in sequence. The bottom trolley and top slab trolley are installed on their corresponding tracks and then pushed forward during subsequent installation.
