Next, adjust the lifting seat, move the new rock drill up to the qualified height, reset the pressure plate, release the pressure on the new rock drill, and continue to adjust the lifting seat until the new rock drill is moved up into place. The workers can then install the new rock drill. After completion, lower the lifting seat to reset it. In this way, through this tooling, the new and old rock drills can be carried, lifted, lifted and adjusted in a more flexible and convenient manner. The operation is more flexible and convenient, saving time and effort. It can also greatly reduce the difficulty of disassembly and assembly of the rock drill, improve operational safety, and be more practical.

[0013] In addition, if the size of the rock drill to be disassembled and assembled changes, the bearing seat with an adaptable placement slot can be flexibly replaced by convenient disassembly and assembly of the bearing seat. The specific replacement operation is: first run the double-rod hydraulic cylinder to shrink its two piston rods, drive the fixed plate to retreat, until the fixed rod is pulled out of the corresponding blind hole, and then pull out the positioning plate, and the original bearing seat can be disassembled. Then, after taking the new bearing seat, first align the two positioning plates on it with the corresponding positioning slots and plug them in place, and then run the double-rod hydraulic cylinder to extend its piston rod until the fixed plate is pressed against the corresponding side. At this time, the fixed rod can be plugged into the corresponding blind hole, and the bearing seat is pressed and plugged in and fixed, and the fixed installation of the new bearing seat can be completed, and the installation is stable and does not affect subsequent use. In this way, the entire bearing seat can be flexibly and conveniently disassembled and replaced, so that the entire tooling can meet the disassembly and assembly requirements of rock drills of different specifications, and at the same time, the entire tooling can be suitable for the disassembly and assembly of other suitable equipment besides rock drills, with a wider range of applications and more flexible and convenient overall use.
