The invention belongs to the technical field of water milling drills, and discloses a prying and clamping mechanism
assembly suitable for a drilling
rock core of a water milling
drill and a regulation and control method. The matching body comprises a prying and clamping cylinder outer
barrel, an outer
barrel end cover, a prying and clamping cylinder middle
barrel, a prying and clamping cylinder middle
piston rod, a prying and clamping
assembly body, a clamping jaw pin shaft, a pivot point and a clamping
jaw opening and closing pin shaft, wherein the pivot point is used for connecting the prying and clamping cylinder middle barrel with a clamping jaw of the prying and clamping
assembly body, so that the clamping jaw can rotate around the clamping jaw pin shaft; a middle
piston rod of the prying and clamping cylinder is connected with a pivot point of the locking sleeve of the prying and clamping assembly body, the
piston rod axially moves to drive the clamping
jaw opening and closing pin shaft to move in the direction of a key groove in one side of the middle cylinder, the locking sleeve is driven to move, and opening and closing of the clamping jaw are directly controlled. An existing hydraulic
system of the water milling drilling
machine is directly used for supplying energy, and an extra power source is not needed. Equipment transportation in
plateau areas is difficult, the mechanism can meet the multi-
caliber sampling requirement only by carrying a light-weight clamping jaw assembly replacement bag, the cost of spare parts is reduced, and the modular structural design, compatibility and
maintainability are excellent.
