Embodiment 1

[0036] Such as Figure 1-4 As shown, the performance detection device of the double-broken wire drum multi-layer winding system includes a drive assembly, a load assembly, a pulley assembly, a control cabinet and a host computer; the pulley assembly is located between the drive assembly and the load assembly.

[0037]Described driving assembly comprises driving platform base 1, and the driving motor 2 that is arranged on driving platform base 1, the first speed reducer 4 and double broken line reel support, the output shaft of driving motor 2 is connected with the first speed reducer through coupling The input shaft of 4 is connected; the double-broken reel 3 to be tested is placed on the double-broken reel support, and the output shaft of the first reducer is connected to the rotating shaft of the double-broken reel to be tested through a coupling.

[0038] The load assembly includes a load platform base 8, and an eddy current power machine 9, a second speed reducer 10, and a...

Embodiment 2

[0047] The detection method based on above-mentioned testing device, comprises the steps:

[0048] Step 1. Place the double-broken reel to be detected on the double-broken reel support, and connect the rotating shaft of the double-broken reel to the output shaft of the first reducer;

[0049] Step 2. Turn on the inverter, PLC controller, host computer, drive motor, eddy current machine, high-definition camera, pin sensor, magnetoresistive sensor, resistive strain gauge and acceleration sensor;

[0050] The driving motor and the eddy current machine rotate in the same direction. The steel wire rope wound on the double-broken reel to be tested is wound out from the double-broken reel to be tested, and wound into the smooth reel after passing through the middle fixed pulley; during this process, The pin shaft sensor collects the stress value of the steel wire rope, the magnetic resistance sensor collects the wear and cross-sectional area change information of the steel wire rope,...

Abstract

The invention discloses performance detection device and method for a multi-layer winding system for a steel wire rope of the dual-broken line reel. The detection device comprises a driving assembly,a loading assembly, a pulley assembly, a control cabinet and an upper computer, wherein the pulley assembly is located between the driving assembly and the loading assembly; the pulley assembly comprises a pulley bracket and a fixed pulley arranged on the pulley bracket; and a to-be-tested dual-broken line reel is wound with the steel wire rope, one end of the steel wire rope is fixed with the to-be-tested dual-broken line reel, and the other end of the steel wire rope bypasses the fixed pulley and is fixedly connected with a smooth roller. The device is applicable to steel wire ropes and dual-broken line reel in different sizes can be used for completely simulating the real working condition of a hoisting mechanism of a crane through the cooperation with the variable hoisting speed and test load so as to acquire test data, so that the basis is provided for the data utilization and analysis; and compared with other testing devices for steel wire rope winding systems, the device is relatively applicable to the failure behavior research of parts of the multi-layer winding system for the steel wire rope of the dual-broken line reel.

Description

technical field [0001] The invention belongs to the technical field of cranes, and in particular relates to a comprehensive performance test device and a detection method based on a double-broken line reel steel wire rope multilayer winding system of a crane lifting mechanism. Background technique [0002] With the development of social economy, the hoisting height of the crane is getting bigger and bigger, and the rope capacity of the wire rope winding system of the hoisting mechanism is getting bigger and bigger. In the past, the increase of rope capacity was generally solved by increasing the diameter and length of the reel of the winding system or changing the magnification of the winding system. If the diameter or length is increased, its weight and moment of inertia will also be increased at the same time, which requires the lifting mechanism to use a motor with a larger capacity, and the winding system takes up more space. While adopting the method of increasing the ...
