Hobbing cutter abrasion test experimental platform and matched measurement evaluation method

Abstract

The invention relates to a hobbing cutter abrasion test and abrasion resistance research experimental platform and a measurement evaluation method, aiming at solving the problems that in the prior art, measurement results have hysteresis, lower in engineering guidance and large in measurement error. The hobbing cutter abrasion test and abrasion resistance research experimental platform is providedwith an abrasive box and a transmission device, wherein an output end of the transmission device is provided with a clamping element used for clamping a cutter ring of a hobbing cutter, and the cutter ring of the hobbing cutter is enabled to be positioned above the abrasive box; the clamping element comprises cutter shaft support seats arranged at the two sides, wherein the cutter shaft support seat arranged at one side is fixed at an output end of the transmission device, and the cutter shaft support seat arranged at the other side is fixed on the abrasive box; the outer ring of a cutter hubis matched with the cutter ring of the hobbing cutter, and the inner ring of the cutter hub is matched with the cutter shaft support seats; the transmission device is also provided with a sensor bracket; an eddy current sensor element is arranged on the sensor bracket and at the position corresponding to the outer side of the outer ring of the hobbing cutter. The hobbing cutter abrasion test andabrasion resistance research experimental platform and the measurement evaluation method have the advantages that measurement is carried out on the cutting basis of simulation of a working environment, and an abrasion test is effectively combined with evaluation; real-time detection is realized, the measurement accuracy is increased, and the equipment application size is wide.

Description

technical field [0001] The invention relates to an experiment platform, in particular, a hob wear test platform for hob wear test and wear resistance research and a matching measurement and evaluation method are designed. Background technique [0002] As an important construction equipment for underground engineering, shield / TBM is playing an increasingly important role in tunnel construction. The hob is a key component of shield / TBM cutter head, which directly interacts with rock formations, and its wear resistance directly affects Shield / TBM tunneling efficiency. At present, due to the lack of relevant wear resistance test platforms and methods, the wear resistance of hobs varies greatly, and the quality is uneven, resulting in abnormal wear of cutter heads in shield / TBM construction, which is not conducive to construction risk control and cost management. , but also cause a waste of social resources. [0003] The main technology for hob wear testing at this stage is to ...
