DIAMOND SAW BLADE-PICK COMBINED ROCK BREAKING TEST DEVICE AND TEST METHOD THEREFOR

摘要

A diamond saw blade-pick combined rock breaking test device and a test method therefor, which relate to the technical field of roadheader cutting test benches. The device comprises a fixed bottom plate (1) on which a saw blade assembly and a box body assembly are provided; a saw blade assembly support frame (4) in the saw blade assembly may drive saw blades to move horizontally, a saw blade group (7) may move vertically along the saw blade assembly support frame (4), and the saw blades are driven by a motor (10) to rotate for cutting; and a box body propulsion cylinder (15) in the box body assembly controls the horizontal movement of a rock fixing device (14), and drives rocks therein to move below the saw blades; and after cutting, cutting and breaking are performed by a pick cutting assembly (12) and a cutting force is collected. First, the sawing of rocks is completed, and then a pick is used to break rock masses that have saw blade cutting cracks. The present device may be used for researching the saw blade-pick combined rock breaking performance to observe the rock breaking effect and cutting force changes of the rocks that have cutting cracks broken by the pick. The movement is stable, the device is easy to control, and the experimental effect is excellent.
