Description
Technical Field
The invention relates to an open-air drilling machine, in particular to a drill rod disassembling system and method of the open-air drilling machine.
Background
Currently, on the ground surface open-air drilling machine in the prior art, a rod replacing system has no professional system design for preventing a drill rod from falling when the drill rod is detached. The technical defect of the existing rod replacing system is that the working position of the drill rod clamp at the upper and lower positions of the drill rod disassembling platform is hidden and difficult to observe. In the disassembly operation of replacing the drill rods, operators can only judge whether the upper drill rod and the lower drill rod are connected or not according to visual inspection and operation experience. Especially, a novice is misoperated under the condition of misjudgment, and the lower disassembly platform is opened in advance when the upper drill rod and the lower drill rod are not connected stably. The consequence is that the underlying shank is caused to drop into the finished drill hole. If the shank falling into the hole is not removed, it is detrimental to the cost of the drill Kong Baofei and the economic cost of the pneumatic drill bit and the shank itself, which are connected to the bottom end of the shank. If the drill rod falling into the drilling hole is to be removed, the drill rod needs to be removed by means of self-operation experience and fortune of the operator. The labor cost and the psychological stress caused by the method are not small.
Aiming at the problems existing in the prior art, the drill rod disassembling system and the method thereof for the open-air drilling machine have important significance.

The pressure sensor judges whether the upper drill rod is screwed with the rotary module or not, if not, the step is returned to, namely, the rotary module is controlled to be screwed with the upper drill rod, and if so, the lower dismounting platform is controlled to execute loosening operation;
The device comprises a lower disassembly platform, a judging module, a re-clamping module, a rotating module, a re-clamping module, a returning step, and a resetting module, wherein the lower disassembly platform is controlled to be in a loosening operation, the lower disassembly platform is lifted to the position of the lower disassembly platform, the lower disassembly platform is controlled to be in clamping operation through a second operation key, the judging module judges whether the lower disassembly platform is clamped to the lower drill rod, the rotating module is controlled to separate the upper drill rod from the lower drill rod if yes, the re-clamping module is controlled to clamp the upper drill rod, the rotating module is controlled to separate from the upper drill rod and send the upper drill rod into a drill rod library, the lower drill rod is regarded as a new upper drill rod, the returning step is controlled to be in screwing with the rotating module, and the re-clamping module is controlled to clamp the upper drill rod and send the upper drill rod into the drill rod library if no.
The drill rod disassembling system and the method of the open-air drilling machine are used for specially solving the technical problem that the drill rod is easy to fall off when the drill rod is replaced by improving the original rod replacing mode. Even if an operator presses the disassembly platform opening control button under subjective or non-subjective consciousness, the drill rod cannot be dropped. Only when the locking control button of the lower dismounting platform is pressed and not released, the rotation movement necessary for dismounting the drill rod can occur. And when the trolley is in a rod replacing mode, the opening of the lower dismounting platform is automatically completed. When the drill bit of the upper drill rod is screwed into the drill bit tail of the lower drill rod and is locked to a stop by rotation, the lower dismounting platform starts to open to be completely opened. If the pushing and reciprocating action of the drill rod is normally performed. When the machine exits from the rod changing mode to the drilling mode, the locking and opening control buttons of the lower disassembling platform are normal in function, when the re-clamping module is started, a failure signal is transmitted to the pressure sensor, and when the re-clamping module is stopped, a re-starting signal is transmitted to the pressure sensor. The process is to prevent the lower drill rod from falling into the rock drilling hole when the rotary module is dismounted from the upper fiber rod, and the lower drill rod is opened due to reverse screwing of the rotary module caused by misoperation, so that an operator can normally and manually control the locking and opening actions of the lower dismounting platform.
