1, complex structure, the cost of manufacture height;

2, because the shield door design load of every subway line is different with rain model, its specification of column and the spacing of one of door body main stress member are also inequality, adopt other linkage must with the supporting design of column, and be subjected to the influence of stud, versatility and very flexible;

3, the installation of existing linkage and column, adjusting are finished simultaneously, and operation easier is big, the construction technical requirement height, and the adjustment time is long.

The utility model content

The utility model is in order to solve existing bearing connecting device complex structure, versatility and very flexible and Installation and Debugging difficult technologies problem, provide a kind of simple in structure, compliance strong and the telescopic easily bearing connecting device of Installation and Debugging.

For solving the problems of the technologies described above, technical solutions of the utility model are a kind of telescopic bearing connecting devices of structure, it comprises by base plate and is located at flanged pipe that the stay pipe of this backplate surface constitutes, constitutes extensible member by expansion link and the gripper shoe of being located at this expansion link upper end that the lower end activity of described expansion link inserts in the endoporus of stay pipe.

In the preferred embodiment of the present utility model, described stay pipe is a box section, is plugged with the insulating part of a band circular inner hole in the endoporus of this box section, is provided with annulus around the upper end of this insulating part, described expansion link is a cylindrical bar, and its lower end activity inserts in the endoporus of insulating part.

Among another embodiment of the present utility model, described stay pipe is a round tube, and described expansion link is a cylindrical bar, and its lower end activity inserts in the endoporus of stay pipe.

Be equipped with bolt hole on described base plate and the gripper shoe.

The structure that the utility model adopts flanged pipe to be connected with the extensible member kink, flanged pipe is connected with a member of subway shield door, and extensible member is connected with another member of subway shield door, can bear on the one hand load such as " Piston Wind " that train produces and crowd's extruding, on the other hand by extensible member relative to the moving of flanged pipe, can guarantee that shield door adapts to the distortion because of platform civil engineering structure generation sedimentation; When between flanged pipe and extensible member, an insulating part being set, realize the electrical isolation between shield door and the top civil engineering structure simultaneously, satisfy the insulating requirements of shield door and surrounding buildings and equipment.This device also can be used for also can being used in particular in the operating mode of linkage two ends requirement insulation in the stressed structure of free movable two other direction of a direction, and this apparatus structure is simple, compliance is strong and Installation and Debugging convenient.
