Abstract

"Elevator balance coefficient steel wire rope tension detection method" is a no-load test method of elevator balance coefficient. The “BCD” device designed and manufactured according to this test method has the characteristics of convenience, quickness and high detection accuracy. In order to clarify the design requirements of this method on the testing equipment, this paper studies the influence of the diameter, length and bending degree of the wire rope on the bending reaction force in the testing process. In this paper, the elevator traction wire rope samples with three diameters of 10mm, 13mm and 16mm, 15, 20, 25, 30 and 40 times the diameter length, are selected respectively. Two groups of axial bending tests were carried out on the samples by using a pressure testing machine. The test results show that: 1. The installation distance of the upper and lower clamping device should be greater than 20 times of the diameter of the measured wire rope; 2. The lifting distance of the lifting device can be more than 5mm to obtain relatively stable test results; 3. The tension obtained from the steel wire rope group cannot be equivalent to the hanging mass of the steel wire rope group, and can only be used as the equivalent mass to calculate the elevator balance coefficient; 4.The testing equipment shall be calibrated separately for each wire rope diameter.
