Abstract

The invention discloses a steel belt tensile fatigue test device, which is characterized by comprising a tightening device, a stretching mechanism, a drive mechanism, a motor and a rack. The tightening device is arranged at the top end of the rack and is used for fixing and adjusting a tightening force of a steel belt to be tested; the stretching mechanism is an eccentric crank slide block mechanism, is perpendicularly arranged at the lower side of the tightening mechanism, and is used for stretching the steel belt to be tested according to a certain frequency; the drive mechanism is connected with a motor shaft, and is used for transmitting output torque of the motor to the stretching mechanism; the motor is fixedly arranged at the bottom part of the rack, and is used for driving the drive mechanism to move. The steel belt tensile fatigue test device provided by the invention has the advantages of compact structure, convenience in adjusting the tightening force, and capability of vertically stretching the steel belt to be tested according to a certain frequency.

Description

technical field [0001] The invention relates to a fatigue test device, in particular to a steel strip tensile fatigue test device, in particular to an elevator steel strip tensile fatigue test device. Background technique [0002] Nowadays, elevators are an essential infrastructure in our daily life. With the development of high-rise buildings, they will be used more and more in the future. Compared with traditional wire rope elevators, steel belt elevators have the following advantages: ①It is not easy to seep and grow, which avoids the trouble of collecting wire ropes; ②Will not break wires or strands, avoiding the trouble of changing wire ropes; Safety; ④The friction force is greater, which can effectively prevent the car from slipping. Enterprises such as Schindler and OTIS in the elevator industry have begun to produce and sell steel belt elevators. [0003] However, after working for a long time, the elevator steel belt will also experience tensile fatigue failure, s...
