[0026] To facilitate those skilled in the art to understand the present invention, specific implementations of the present invention are described below with reference to the accompanying drawings.

[0027] like Figure 1 , 2 As shown, this embodiment provides a split mobile construction platform system for a subway station that can avoid the middle plate 9 and the column 11, including a first mobile platform 2 located on the middle plate 9, a second mobile platform 3 located under the middle plate 9 and on one side of the column 11, and a third mobile platform 4 located under the middle plate 9 and on the other side of the column 11. The lower part of the truss structure of each platform is provided with a walking mechanism, and a truss corridor 1 is connected between the lower second and third mobile platforms 4, so that the two lower platforms are connected as a whole, which is convenient for construction. One end of the truss corridor 1 is hinged to the second mobile platform 3, and the other end is plugged into the third mobile platform 4. When a certain column 11 needs to be avoided or is not needed, the plug-in connection between the truss corridor 1 and the third mobile platform 4 is cancelled, and the truss corridor 1 is erected and fixed at the end of the second mobile platform 3. During the construction process, the connection of the truss corridor 1 can be released to form a separate structure for the two lower platforms. The column 11 can be avoided for mobile construction. The lower platform structure can be moved as a whole or in parts, which allows flexible construction. One end of the truss corridor 1 is hinged to the second mobile platform 3, and the other end is connected to the third mobile platform 4. Installation and dismantling are convenient and will not reduce construction efficiency.

[0028] The second and third mobile platforms use a separate structure to reserve the connection position of the truss corridor 1, which reduces the large-scale disassembly and assembly process of the platform during construction. When moving longitudinally, it can quickly pass through the middle plate 9 and the column 11. The structural stability of the platform is good and it can still maintain good support during the movement. The separate structure will not affect the overall stability of the structure, thereby improving the overall safety performance of the platform. After the truss corridor 1 connects the second and third mobile platforms, it acts as a truss structure, and the two ends are connected and fixed, thereby enhancing the stability between the two platforms.

[0029] The split mobile construction platform system of the utility model is mainly composed of three parts, which are divided into the first mobile platform 2 at the top and the second and third mobile platforms at the bottom. The split of the upper and lower parts solves the problem that it is impossible to effectively avoid the middle plate 9 for mobile construction, and the split in the lower part solves the problem that it is impossible to effectively avoid the column 11 for mobile construction. The first mobile platform 2 at the top and the second and third mobile platforms at the bottom can be translated longitudinally as a whole through the walking mechanism, and can also be moved by individual control. The entire platform is driven by a servo motor, and each part can move as a whole and individually to meet the requirements of efficiency and flexibility of modern subway construction platforms. In addition, the construction platform can move one link at a time, which improves the fault tolerance of component assembly.

[0030] The first, second and third mobile platforms are mainly composed of bottom rails, walking mechanisms, construction platforms, hydraulic devices and ladder handrails. The truss structure can use Q235 steel. Each assembly part is connected by a sheet-mounted flange.

[0031] like Figures 3 to 8 As shown, the end of the truss corridor 1 near the second mobile platform 3 is hinged to the second mobile platform 3 through a hinge 5, and the end of the truss corridor 1 near the third mobile platform 4 is plugged with the third mobile platform 4 through a plug-in assembly. The plug-in assembly includes a telescopic rod 6 installed on the truss corridor 1 and an Ω-shaped clamp 7 installed on the third mobile platform 4. The extended end of the telescopic rod 6 is inserted into the Ω-shaped clamp 7 to plug the truss corridor 1 and the third mobile platform 4.

[0032] In this embodiment, there are two truss corridors 1 which are arranged in parallel, and the gap between the two truss corridors 1 can accommodate one column 11 .

[0033] In this embodiment, two hinges 5 and two telescopic rods 6 are respectively provided at both ends of each truss corridor 1 .

[0034] like Figure 4 As shown, specifically, the hinge 5 includes a rotating shaft and two connecting plates, the rotating shaft is hinged to the two connecting plates, and the two connecting plates are respectively fixedly connected to the second mobile platform 3 and the third mobile platform 4 by screws.

[0035] Specifically, Figures 6 to 8 As shown, the telescopic rod 6 is configured as a two-section stepped rod, including a first stepped rod 61 and a second stepped rod 62 located outside the first stepped rod 61 .

[0036] like Figure 6 As shown, one end of the second step rod 62 passes through the side wall of the truss corridor 1 and is threadedly connected to the flange 63 fixed on the truss corridor 1, and the first step rod 61 cooperates with the Ω-shaped clamp 7. Both end surfaces of the Ω-shaped clamp 7 are fixed to the third mobile platform 4 by screws.

[0037] like Figure 7 , 8 As shown, two slide grooves 621 are symmetrically provided on the inner wall of the second step rod 62 along the axial direction, the opening end of the slide groove 621 starts from the end of the second step rod 62 away from the first step rod 61, the length of the slide groove 621 is less than the length of the second step rod 62, and the end of the slide groove 621 forms a limit slot for the first step rod 61 to be connected in place. Two raised strips 611 are radially symmetrically provided on the first step rod 61 near the end of the second step rod 62, and the raised strips 611 are adapted to the slide groove 621 to prevent the first step rod 61 from sliding out, and the first step rod 61 can be extended and retracted through the slide groove 621 to achieve the purpose of retractability.

[0038] like Figures 7 to 9As shown, two telescopic rods 6 are arranged on the right side of the truss corridor 1, and the second step rod 62 is fixedly connected to the truss corridor 1 through two flanges 63. The flange 63 on the left side is not through and is provided with a partial internal thread, and the middle of the flange 63 on the right side is a through hole, and the bottom end of the second step rod 62 is provided with an external thread, which can be connected to the side plate of the truss corridor 1 and the flange 63 respectively.

[0039] Correspondingly, two Ω-shaped clamps 7 are installed on the third mobile platform 4 on the right side, through which the first step rod 61 can pass. The Ω-shaped clamps 7 are fixedly connected to the third mobile platform 4 by bolts. When the truss corridor 1 is lowered during construction, the telescopic rod 6 extends into the Ω-shaped clamps 7. Figure 6 A threaded hole 71 is provided on one side wall of the Ω-shaped clamp 7 for installing a set screw (not shown in the figure). The set screw is used to lock the first step rod 61 inserted into the Ω-shaped clamp 7, so that the connection between the telescopic rod 6 and the Ω-shaped clamp 7 can be further strengthened. When the second and third mobile platforms 4 need to move, the locking screw is loosened and the telescopic rod 6 is retracted to the corresponding position so that it is no longer connected to the third mobile platform 4 on the right, and the truss corridor 1 is erected and stored on the side of the second mobile platform 3.

[0040] In another scheme, bolt holes can be opened on the side wall of the Ω-shaped clamp 7 and the first step rod 61 respectively. When the bolt hole of the first step rod 61 corresponds to the bolt hole on the side wall of the Ω-shaped clamp 7, bolts and nuts are installed on the bolt holes. When the construction platform needs to be moved, the bolts are removed and the telescopic rod 6 is retracted to the corresponding position so that it is no longer connected to the right construction platform. The truss corridor 1 is erected and stored on the side of the second mobile platform 3.

[0041] like Fig.10 As shown, the split mobile construction platform system also includes an electric push rod 8, which is used to drive the truss corridor 1 to stand up or down. The fixed end of the electric push rod 8 is hinged on the second mobile platform 3, and the extended end of the electric push rod 8 is hinged on the truss corridor 1. The purpose of standing up and lowering the truss corridor 1 is achieved by extending the length of the electric push rod 8. When the overall construction platform is running, it rotates and folds to the left construction platform and stops the electric push rod 8, which plays a role in fixing the truss corridor 1. The truss corridor 1 is perpendicular to the left construction platform, so as to achieve the purpose of folding and storage.

[0042] In another embodiment, the electric push rod 8 can be replaced by a rope with a hook, the rope is used to pull the truss corridor 1 to stand up, one end of the rope is connected to the hanging ring provided on the second mobile platform 3 through the hook, and the other end of the rope is connected to the hanging ring provided on the truss corridor 1 through the hook. Other structures remain unchanged and will not be repeated here.

[0043] The above-described implementation methods of the utility model do not constitute a limitation on the protection scope of the utility model. Any modification, equivalent replacement and improvement made within the spirit and principle of the utility model shall be included in the protection scope of the claims of the utility model.
