Glass curtain wall performance detection device

The invention provides a glass curtain wall performance detection device comprising a track assembly which is designed into a linear, S-shaped, arc-shaped or O-shaped closed structure according to the overall contour of a building glass curtain wall; the rail trolley is connected to the rail assembly in a rolling manner; the retracting and releasing mechanism is arranged on the small rail car; and the detection mechanism is connected with the take-up and pay-off mechanism through a pair of mooring ropes, and the mooring ropes are driven by the take-up and pay-off mechanism to pull the detection mechanism to move up and down. The track trolley bears the retracting and releasing mechanism to advance on the track assembly, after the track trolley reaches a designated position, the track trolley stops moving, the retracting and releasing mechanism lowers the detection mechanism to a designated area, by means of movement of the track trolley and retracting and releasing of the detection mechanism through the retra
