Abstract
The invention discloses a test method of an elevator balancing coefficient. The test method comprises the following steps of placing a weighing sensor on an elevator counterweight buffer, enabling an elevator to move upwards the topmost story, then switching off a power supply of the elevator, and enabling the elevator to slide slowly and move upwards until counterweight is completely pressed on a buffer and the elevator cannot move upwards any more by manually loosening a brake of the elevator; keeping the brake of the elevator in an opening state, and reading a measuring value on the weight sensor at the moment, wherein the measuring value is the sum of a difference value of an elevator car and the counterweight and the weight of a drag steel wire roper on the upper end of the counterweight, and the difference value of the elevator car and the counterweight can be obtained by rejecting known weight of the drag steel wire rope; and calculating and obtaining the elevator balancing coefficient according to a balancing coefficient calculation formula of a drag type elevator: K=(P-W)/Q. The invention also provides an intelligent measuring instrument for quickly and conveniently measuring the elevator balancing coefficient.
