Abstract

The invention discloses a multifunctional rock cutting test bench, which comprises a bottom plate, a cutter module and a rock module. The threaded holes on the base plate are used to install the cutter module and rock module. The plunger cylinder and plunger rod of the cutter module can realize the expansion and contraction of the cutter and the linear cutting of single or multiple teeth, and the hydraulic motor can realize the rotary cutting. The motor of the rock module realizes the translation of the rock through a first-stage gear reduction device and a rack and pinion device. The four plunger cylinders and plunger rods can realize the lifting and tilting of the rock. The pressing block, rock fixing plate and bolts, nuts, Flat spacers fit to achieve rock fixation. The cutter module of the present invention can realize rotary cutting, linear cutting, and single-tooth cutting and multi-tooth cutting under the state of linear cutting by replacing the cutter, and the rock module can realize rock left and right translation, up and down stretching and tilting, and rock fixation.

Description

technical field [0001] The invention relates to a multifunctional rock cutting test bench, which belongs to the technical field of rock cutting research equipment. Background technique [0002] With the rapid development of my country's shipping industry and the vigorous development of infrastructure projects such as ports and waterways, the domestic demand for dredging ships is increasing. Cutter suction dredgers and trailing suction dredgers are the two most commonly used dredging ship types, but both have problems such as weak capacity, low efficiency, and severe wear during rock cutting. However, with the gradual widening and deepening of domestic and foreign port channels, the number of dredging projects for rocky bottom is increasing. Therefore, it is urgent to study new rock cutting equipment to improve the efficiency of rock dredging and reduce the cost of rock dredging. [0003] At present, most of the research in the domestic dredging industry is a large-scale te...
