The invention relates to a T-shaped
elevator guide rail flatness detection
system, which comprises a support, a transverse conveying device, a longitudinal conveying device, a guide rail flatness detection device and a guide rail turnover device, wherein the transverse conveying device, the longitudinal conveying device, the guide rail flatness detection device and the guide rail turnover device are arranged on the support. The guide rail flatness detection device comprises a
laser emitter and a
laser receiving target, wherein the
laser emitter and the laser receiving target are arranged on alinear rail spanning the transverse conveying device. The
system adopts the
laser detection method to detect the flatness of a guide rail. The
system is accurate in detection result, simple and convenient to operate and free of complex
machine equipment. According to the system, the automatic turnover of the guide rail is realized and the production efficiency is improved. The labor cost is saved,and the economic benefit of enterprises is improved. The turnover device is provided with a buffer mechanism, so that the
impact when an
elevator guide rail is in contact with a buffer block is reduced. The
elevator guide rail is protected. Two cylinders are respectively arranged on the turnover device and the buffer driving device of the mechanism, so that the turnover block and the buffer blockcan be effectively controlled. Therefore, the turnover process can be well controlled.
