Tension detection device for tooth-shaped belt of metro shielding door

The utility model provides a tension detection device for a tooth-shaped belt of a metro shielding door, belongs to the technical field of belt tension detection, and aims to solve the problems that the vibration frequency of the belt is possibly changed due to external factors during measurement, and the detection result has a large error. Comprising a detection table; a detection mechanism is fixedly arranged at the top of the detection table, and a fixing device is fixedly arranged at the top of the sliding seat; a connecting mechanism is fixedly arranged on the outer side of the fixing device, and an auxiliary device is fixedly arranged on the outer side of the fixing device. Through the hydraulic rod and the detection seat, the effect that the detection rod applies pressure to one side of the to-be-detected belt, so that the side of the to-be-detected belt is deformed is achieved; the distance measuring instrument is matched with the sliding frame, so that the purpose of measuring the deformation size of
