Installing device for adjusting pipeline angle

The invention discloses an installing device for adjusting the pipeline angle. An installing base, a pipeline inclination angle adjusting device and a pipeline positioning device are included. The pipeline inclination angle adjusting device is rotationally connected to the installing base. The installing base is in sliding connection with a limiting table. A limiting groove is formed in the limiting table. The bottom of the pipeline positioning device is rotationally connected with a lifting device. The lifting device is kept in a vertical state. The bottom end of the lifting device is matchedin the limiting groove. According to the installing device, multi-time inclination angle adjustment can be conducted on a pipeline within the adjustable range, the pipeline installing accuracy is improved, and seal performance and safety of a water drainage system are improved. The lifting device is constantly kept in the vertical state and supported in the limiting groove of the limiting table,force exerted on the pipel
