The invention discloses a universal connection device for driving a shield spiral conveyer. The universal connection device comprises a front ball base, a rear ball base, a universal spherical rotor, at least two fixing assemblies and a rotor connecting piece. The universal spherical rotor comprises a rotating rod and a universal ball head. One end of the rear ball base and the front ball base are connected and form an internal cavity, and the other end of the rear ball base is connected with a motor connecting piece. The universal ball head is arranged in the internal cavity and connected with the inner wall of the front ball base through the fixing assemblies. The rotating rod is connected with the front ball base through the rotor connecting piece. A sealing piece is arranged between the rotating rod and the rotor connecting piece. According to the universal connection device for driving the shield spiral conveyer, the service life of a driving device of the spiral conveyer can be prolonged.
Description
technical field [0001] The invention relates to the technical field of a shield screw conveyor, in particular to a universal connection device for driving a shield screw conveyor. Background technique [0002] The screw conveyor is one of the important components of the soil discharge system of the earth pressure balance shield machine. During shield tunneling construction, the main function of the screw conveyor is to discharge the excavated soil from the sealed soil bin with pressure to the shield machine. , in this process, the soil forms a sealed soil plug in the screw conveyor to prevent the water in the soil from flowing out and keep the soil pressure in the sealed chamber stable; in addition, the amount of soil discharge can also be adjusted by changing the speed of the screw conveyor, that is By adjusting the water and soil pressure in the sealed soil bin, it can maintain a dynamic balance with the water and soil pressure on the excavation surface. When working, t...
