Flatness detection device for T-shaped elevator guide rail

The utility model discloses a T-shaped elevator guide rail flatness detection device, which comprises a mounting plate, a first dial indicator, a second dial indicator and a T-shaped elevator guide rail, a mounting frame is fixedly mounted on the upper surface of the mounting plate, and a groove is formed in the inner top wall of the mounting frame. According to the utility model, the magnetic base slides along the sliding groove, so that the head of the first dial gauge is in contact with the side surface of the convex part of the T-shaped elevator guide rail, then the fixed bolt is unscrewed to make the head of the second dial gauge be in contact with the upper surface of the T-shaped elevator guide rail, and then the motor is driven to drive the T-shaped elevator guide rail through the spiral transmission of the threaded column and the sliding block. Therefore, the first dial indicator can be driven to move on the side face of the protruding part of the T-shaped elevator guide rail, meanwhile, the second d
