Elevator load test method based on liquid flow accurate control

Abstract

The invention discloses an elevator load test method based on accurate liquid flow control. A detection vehicle capable of moving to the vicinity of a detection point is included, detection equipment is mounted on the detection vehicle and comprises a liquid storage system, a liquid supply system, a control system and a detection weight. Other devices in the detection equipment are respectively connected and controlled through the control system. After the liquid injection amount is set on the control system, the liquid supply system is started, and liquid is injected into the detection weight to test the load capacity of an elevator to be detected. A liquid signal is fed back to the control system from the liquid supply system to monitor the liquid state and check the condition of the elevator to be detected, and a switch of the elevator to be detected is operated to be closed to continue the test. After the test is finished, the liquid in the detection weight is completely pumped back to the liquid storage system, the detection vehicle is lightly carried back and then is transported to the vicinity of the next detection point, so that the detection efficiency and the detection accuracy of the elevator load test are improved, and the problems of high labor intensity of workers and inaccurate measurement data in the prior art are solved.

Description

technical field [0001] The invention relates to the technical field of elevator safety detection, in particular to an elevator load test method based on precise control of liquid flow. Background technique [0002] In the elevator balance coefficient test and the elevator 125% load test, the existing technology needs to manually carry the weight according to the different requirements of the elevator counterweight. After the test, the tester will carry the weight out of the car. This method wastes a lot of manpower and time, and greatly reduces work efficiency. At the same time, it is also very common that the test data is inaccurate because the weight of the loaded weight does not match the calculated weight due to human factors. [0003] Moreover, the calculation of experimental loads in the prior art is manually calculated by the experimenter, and in actual operation, rework often occurs due to calculation errors by the operator. [0004] Patent CN 110044650 A discloses...
