The invention relates to an open-air drilling machine, in particular to a drill rod disassembling system and a drill rod disassembling method of the open-air drilling machine.
Background
At present, on the ground surface open-pit drilling machines in the prior art, rod replacement systems have no professional system design for preventing the drill rod from falling when the drill rod is disassembled. The technical defect of the existing rod replacing system is that the working parts of the drill rod clamping devices at the upper and lower positions of a drill rod disassembling platform are hidden and difficult to observe. During the disassembly operation when changing the drill rods, an operator can judge whether the upper drill rod and the lower drill rod are connected or not only by visual inspection and operation experience. Especially, a novice user mistakenly operates under the condition of misjudgment, and opens the lower disassembling platform in advance when the upper drill rod and the lower drill rod are not connected stably. The consequence of this is that the lower drill rod falls into the finished rock hole. If the drill rod falling into the rock hole cannot be removed, the danger is that the rock hole is scrapped and the economic cost of the pneumatic drill bit connected to the bottom end of the drill rod and the drill rod itself is lost. If a drill rod dropped into a rock hole is to be removed, this is done by means of the operator's own operating experience and luck. The labor cost and the induced psychological stress are not small.
Aiming at the problems in the prior art, the drill rod disassembling system and the drill rod disassembling method of the open-air drilling machine are of great significance.

The invention relates to a drill rod dismounting system of an open-air drilling machine and a method thereof, which specially solve the technical problem that a drill rod is easy to drop when the drill rod is replaced by the ground open-air drilling machine by improving the original rod replacing mode, and are improved compared with the original system design as follows: after the machine switches to the pole change mode, the lower release platform deployment control button function must fail. Even if an operator presses the opening control button of the disassembling platform under subjective or non-subjective consciousness, the drill rod cannot be dropped. The necessary rotational movement to remove the drill rod can only occur when the lower removal platform locking control button is pressed and not released. When the trolley is in the rod changing mode, the opening of the lower disassembling platform is automatically completed. When the drill bit of the upper drill rod is screwed into the drill bit shank of the lower drill rod and is rotationally locked to stop, the lower disassembly platform begins to be opened to be completely opened. If the drill rod is normally pushed to reciprocate. When the machine exits from the rod changing mode to the drilling mode, the locking and opening control buttons of the lower dismounting platform have normal functions; when the re-clamping module is started, a failure signal is transmitted to the pressure sensor, and when the re-clamping module is terminated, a restart signal is transmitted to the pressure sensor. The process is to prevent the situation that when the rotary module is disassembled from the upper fiber rod next time, the rotary module is reversely screwed again due to misoperation, so that the lower drill rod clamps open, the lower drill rod falls into the rock drilling hole, and an operator can normally and manually control the locking and opening actions of the disassembling platform.
