The adjustment mechanism drives the segment grabbing assembly 200 to swing and rotate in multiple directions relative to the second assembly arm 303; between the assembly arm and the first turntable, and between the first assembly arm and the second assembly arm In this embodiment, a swing-type oil cylinder is used for connection to provide pitch drive. It can also be driven by a telescopic rod-type oil cylinder or other mechanisms to drive mutual swinging actions. Among them, the second assembling arm is a telescopic arm structure, and is provided with a telescopic power push rod that drives the telescopic action, so as to facilitate targeted adjustments for different distances in different directions.
[0043] This embodiment provides the specific structures of the following types of adjustment mechanisms. The adjustment mechanism can be a multi-degree-of-freedom turntable or a universal adjustment head arranged at the end of the second assembly arm, or other existing technologies that can achieve this The adjustment assembly with local structural features satisfies the swing of multiple degrees of freedom and the rotation in the circumferential direction, so as to realize the fine adjustment and assembly of the tube slice orientation; the adjustment mechanism may also include two swing cylinders arranged in a cross, a third assembly arm and a second assembly arm. With three revolving platforms, the third assembling arm swings in multiple degrees of freedom relative to the second assembling arm, and the segment grabbing assembly is connected to the third assembling arm through the third revolving platform. The second form is selected in the figure in this embodiment.
[0044] In the above structure, the assembly arm assembly may also include more articulated assembly arms, and is not limited to a two-stage or three-stage assembly arm structure. The present embodiment only optimizes the structural features to achieve structural integration and compactness. It is easy to control and transfer, and provides corresponding structural features to optimize the product structure and promote construction efficiency and construction quality. In addition, a base can be fixed on the corresponding first turntable, The base can also be a telescopic structure to adjust the working range of the entire assembly arm assembly, or a new second turntable 309 is provided between the first assembly arm and the second assembly arm, which can enable the second assembly While the arm swings relative to the first assembly arm, it can also rotate circumferentially. The purpose is to further optimize the structure according to the different tunnel cross-sectional shapes and adjust the difficulty of segment assembly to ensure construction quality. figure 2 Shown.
[0045] The specific structure of the support arm assembly in this embodiment includes a first support arm 501 and a second support arm 502. A fourth turntable 503 is provided between the first support arm 501 and the crawler vehicle 100; one end of the second support arm 502 It is hinged with the first support arm 501, the other end of the second support arm 502 is hinged with the service platform 400, and adjustments are arranged between the first support arm 501 and the second support arm 502, and between the second support arm 502 and the service platform 400. The horizontal power push rod 504 realizes the rotation, lifting and leveling of the service platform, which is convenient for the working staff. In this embodiment, the first support arm or/and the second support arm is a telescopic arm structure, and is provided with a telescopic power push rod that drives the telescopic action; at the same time, the support arm assembly may also include more articulated support arms, It is not limited to a two-stage or three-stage support arm structure.
