Drilling and milling type tunneling machine cutting experimental mechanism

Abstract

The invention relates to a drilling and milling type tunneling machine cutting experimental mechanism. The drilling and milling type tunneling machine cutting experimental mechanism comprises a cutting head and a rocker arm part; the cutting head is composed of a tooth part cutting rotating cutter disc, a hobbing cutter disc, an end cover, a planetary gear, a sun gear and an inner gear; the rockerarm part is composed of a reduction gearbox and a driving motor; the driving motor drives the tooth part cutting rotating cutter disc and the hobbing cutter disc to rotate through the reduction gearbox, and a traction portion drives a rocker arm to swing left and right through a pin shaft, so that the cutting radius and the cutting area are increased, the cutting capacity is improved, rock breaking is easier in the tunneling process, the purpose of rapid tunneling is achieved, the rock breaking capacity of an underground space project can be improved, the construction progress time is shortened, tooth cutting and hobbing are integrated, and the cutting efficiency is greatly increased. The tunneling machine cutting mechanism is compact in structure, simple in mechanism, low in cost and good in rock breaking effect, and effectively reduces the tunneling ratio energy consumption of the tunneling.

Description

technical field

[0001] The invention relates to the fields of tunnel excavation in underground space engineering, coal and mineral mining, in particular to a drilling and milling type roadheader cutting experimental mechanism. Background technique

[0002] The cutting head is the core part of the cutting of the roadheader, and the design of the cutting head often determines the performance of the whole roadheader. A roadheader with good performance should have the advantages of high cutting efficiency, wide cutting range, easy handling and flexible cutting. The quality of the cutting head has a crucial impact on the performance of the whole machine, and the price of the cutting head is also very expensive. Therefore, the design and development of cutting head is the core issue of roadheader research and development. However, in this regard, there is still a lack of scientific and systematic design methods for cutting heads in China; lack of sufficient theoretical basis and...
