Problems solved by technology

And because the motor is the driving power source during the test, and its load is the load generated by the steel wire rope on the drum, therefore, the configuration of the motor, coupling, brake and reducer is the same as that of the drum when it is actually working, and is unique. The capacity changes. For different reels and different loads, it is necessary to configure matching motors and reducers, and the test cost is relatively high.
During the test, the two sets of devices need to start working at the same time, and the power consumed is twice the power required by the load, which consumes a lot of energy

Abstract

The invention discloses a drum stress test device and a method thereof and relates to the technical field of crane drum stress tests. The drum stress test device comprises a duplex-drum assembly, a steel wire rope (10), a drive assembly and a mounting rack (15). The duplex-drum assembly comprises a duplex drum (1). The test device further comprises a loading assembly. The loading assembly comprises a pulley set (11), a hydraulic oil cylinder (12) and a hydraulic pump station (13). According to the drum stress test device and the method, only one drive device set is needed, and the drive assembly and the loading assembly can be used as universal pieces to be suitable for different drums; the test cost is lowered, power consumption is lowered, and energy is saved.

Description

technical field [0001] The invention relates to the technical field of crane drum detection, and more particularly to a drum stress testing device and a method thereof. Background technique [0002] At present, in the research on the force of the reel, two sets of the same hoisting drive device are generally used, which are arranged horizontally and symmetrically. Each set is composed of a reel device, a reducer, a brake, a coupling and a motor. Two sets of hoisting drive devices are intertwined and connected together by wire ropes. One of them is the active device and the other is the loading device. When carrying out the loading test of the multi-layer winding drum, due to the limitation of the allowable deflection angle of the steel wire rope, the distance between the two sets of hoisting drives needs to be arranged far, and the requirements for the test site are very high. And since the motor is the driving power source during the test, its load is the load generated b...
