Automatic detecting and testing system for tripper

Abstract

The invention relates to a kind of automatic testing system for safety devices. The test bench is equipped with the stand, and the main spindle, motor, reduction device and flywheel on the stand. A torque / speed sensor and a displacement sensor are also available on the test bench. The torque / speed sensor is serial connected between the main spindle of the test bench and the safety device. The signals from the sensors are first sent to the measurement instruments or A / D card and then are transmitted to the computer. The displacement sensor is placed at the rear of the safety device and it is connected to the A / D card and the computer. The displacement sensor detects the displacement of the nut on the rear of the safety device. The test bench is driven by a motor. Through the high-speed spindle, the braking energy of the test bench is transmitted to the flywheel charging device which is connected to the high-speed spindle. While performing a test, the safety device is charged with the energy stored in the flywheel charging device. The torque gauge samples the torque / speed signals from the main spindle of the safety device. The displacement of the safety device during a braking is automatically measured by the displacement sensor. The measurements are conversed by the A / D card and the test result is obtained. Then the computer automatically generates a test record and test report. The charging of this test bench is realized through the adjustable multi-level flywheel charging device.

Description

technical field [0001] The invention relates to a safety device detection and test system for construction lifting equipment, in particular to an automatic detection and test system for a safety brake on a rack-type elevator. Background technique [0002] The anti-drop safety device is the most important safety device in the construction elevator, which is directly related to the safety of the occupants. Calibration and factory inspection must be carried out before the safety device is used, and regular inspections must be carried out during use. The relevant standard JG121-2000 "Gear Conical Drum Progressive Falling Safety Device for Construction Elevators" stipulates the inspection method and content. [0003] The inspection work of the safety device is generally carried out on a special inspection test bench. At present, there are only several safety device test benches in China that have the following problems: [0004] 1. The measurement range is narrow, which cannot...
