The invention discloses a modularized variable cross-section tunnel lining trolley and belongs to the field of tunnel trolleys. The modularized variable cross-section tunnel lining trolley comprises a portal-frame mechanism, a support mechanism, a travelling mechanism, bottom vertical beams, a steel rail, a sleeper, a top formwork and side formworks. The upper ends of a first portal-frame stand column, a second portal-frame stand column, a third portal-frame stand column and a fourth portal-frame stand column of the portal-frame mechanism are fixedly connected with four corners of a cross beam frame formed by connecting a front portal-frame cross beam, a rear portal-frame cross beam, a left portal-frame cross beam and a right portal-frame cross beam together, and the lower ends of the first portal-frame stand column, the second portal-frame stand column, the third portal-frame stand column and the fourth portal-frame stand column of the portal-frame mechanism are fixedly connected with the left and right bottom vertical beams. The modularized variable cross-section tunnel lining trolley is characterized in that the front portal-frame cross beam, the rear portal-frame cross beam, the left portal-frame cross beam, the right portal-frame, the first portal-frame stand column, the second portal-frame stand column, the third portal-frame stand column and the fourth portal-frame stand column are each formed by connecting n unit modules in sequence, and n is a positive integer; according to the structures of the unit modules, the upper ends of a first module stand column, a second module stand column, a third module stand column and a fourth module stand column are fixedly connected with upper flange plates correspondingly, the lower ends of the first module stand column, the second module stand column, the third module stand column and the fourth module stand column are fixedly connected with lower flange plates correspondingly, a cube is formed, and reinforcing ribs are installed on the side surface of the cube. The modularized variable cross-section tunnel lining trolley has the advantages that for tunnel cross sections with different sizes, different quantities of unit modules can be adopted and connected to met the requirement of a project; designing manufacturing cost can be saved, and producing efficiency can be improved.
Description
technical field [0001] The invention belongs to the field of tunnel trolleys, and in particular relates to a modular variable-section tunnel lining trolley. Background technique [0002] Nowadays, with the rapid development of the transportation industry, the lining of developed tunnels will be encountered in railways, highways, submarine transportation and urban underground transportation. At present, most of the tunnel lining projects are designed and built first. Carry out lining construction on the tunnel platform, dismantle the platform after a section is completed, redesign and build the platform, and carry out the lining work of the next section. Its disadvantages are that the tunnel lining trolley has a single structure and function, low production efficiency, waste of work and waste, and uneconomical. The patent application number is CN201521136685.9 "Large-span multi-section variable-diameter tunnel lining trolley". Its structure includes gantry, formwork, support...
