The invention provides a multifunctional water hammer drill-rod lifter. The multifunctional water hammer drill-rod lifter comprises a drill-rod lifter trolley mounted on a water hammer drilling machine propelling beam, a drill-rod lifter base plate mounted on the drill-rod lifter trolley and a drill-rod lifter base fixed to the drill-rod lifter base plate. The drill-rod lifter base comprises an upper half drill-rod lifter base and a lower half drill-rod lifter base. An upper drill-rod lifter sleeve and a lower half drill-rod lifter sleeve are mounted on the upper drill-rod lifter base and thelower drill-rod lifter base through bolts. The upper drill-rod lifter sleeve and the lower half drill-rod lifter sleeve are combined to form a circular hole allowing a drill rod, a root canal sleeve and a rock core outer tube. Lug blocks are fixed to the connecting ends of the lower half drill-rod lifter base and the upper half drill-rod lifter base. The lug blocks are attached to the front and rear sides of the connecting ends. The lug blocks are provided with circular holes allowing pins to pass through. The ends of the pins are provided with safety pins. A pin rod fixed to the middle of a rectangular panel of the drill-rod lifter trolley penetrates into the circular hole formed in the middle of the drill-rod lifter base plate. The drill-rod lifter base plate is connected with the rectangular panel of the drill-rod lifter trolley through bolts. The multifunctional water hammer drill-rod lifter has the advantages of being reasonable in structure design, convenient to disassemble and assemble, stable in connection and suitable for different diameters of drilling machine drill rods, root canal sleeves and rock core outer tubes.
Description
technical field [0001] The invention relates to the technical field of drill props, in particular to a multi-functional water hammer which is suitable for drill pipes of drilling rigs, follower casings, and outer core pipes, reduces the disturbance of the drill pipes of the drilling rig ahead of the water hammer, and facilitates rod addition and removal. Drill pipe supporter. Background technique [0002] Drill pipes, follower casings, and core outer pipes of water hammer advanced drilling rigs have various thickness specifications: the diameters of commonly used drill pipes are 50mm, 70mm, 76mm, and 89mm, and the diameters of follower casings are 102mm, 108 mm, 114 mm, 127 mm, 140 mm, 152 mm, and the diameter of the core outer tube is 54 mm, 58 mm, 73 mm, 89 mm. There are two ways to install the drill pipe, heel casing, and core outer pipe: one is to manually insert the drill pipe, heel casing, and core outer pipe into the brazing sleeve; the other is to put the brazing sl...
