Description

Technical Field

[0001] The invention relates to an open-pit drilling rig, in particular to a drill rod disassembly system and method of the open-pit drilling rig. Background Art

[0002] At present, on the ground open-pit drilling rigs of the prior art, the rod changing system does not have a professional system design to prevent the drill rod from falling when disassembling the drill rod. The technical disadvantage of the current rod changing system is that the working parts of the drill clamps at the upper and lower positions of the drill rod disassembly platform are relatively hidden and difficult to observe. When the operator is performing the disassembly operation when changing the drill rod, he can only judge whether the upper and lower drill rods are connected well by visual inspection and operating experience. Especially for novices, they misoperate under misjudgment and open the lower disassembly platform in advance when the upper and lower drill rods are not connected securely. The consequence is that the lower drill rod falls into the completed rock drilling hole. If the drill rod that falls into the rock drilling hole cannot be removed, the harm is that the rock drilling hole is scrapped, and the economic cost loss of the pneumatic rock drilling head connected to the bottom of the drill rod and the drill rod itself is caused. If the drill rod that falls into the rock drilling hole is to be removed, it is necessary to rely on the operator's own operating experience and luck. The labor cost and psychological pressure caused by it are not small.

[0003] In view of the problems existing in the prior art, it is of great significance to provide a drill rod disassembly system and method for an open-pit drill rig. Summary of the invention

[0004] In order to solve the above problems, the present invention provides a drill rod disassembly system and method for an open-pit drilling rig.

[0005] To achieve the above-mentioned purpose, the drill rod disassembly system of the open-pit drilling rig of the present invention comprises a control module, a lower disassembly platform, a first operating key and a second operating key; the lower disassembly platform is used to lock and / or release the lower drill rod; the drill rod disassembly system comprises a rock drilling mode and a rod changing mode; when the drill rod disassembly system is in the rock drilling mode, the first operating key is used to control the lower disassembly platform to perform a loosening operation, and the second operating key is used to control the lower disassembly platform to perform a clamping operation; when the drill rod disassembly system is in the rod changing mode, the control module is used to cut off the connection between the first operating key and the lower disassembly platform; at this time, the first operating key cannot control the lower disassembly platform to perform a loosening operation;

[0006] Furthermore, it also includes an upper drill rod, a pressure sensing module and a rotation module; when the drill rod disassembly system is in a rod changing mode, the pressure sensing module is used to determine whether the upper drill rod is tightened with the rotation module, and if so, the lower disassembly platform is controlled to perform a loosening operation; the rotation module is used to control the tightening with the upper drill rod;

[0007] Furthermore, it also includes a judgment module and a re-clamping module; the judgment module is used to judge whether the lower disassembly platform clamps the lower drill rod; the re-clamping module is used to clamp and fix the upper drill rod;

[0008] The present invention also provides a drill rod disassembly method for an open-pit drilling rig, comprising a control module, a lower disassembly platform, a first operating key and a second operating key, the method specifically comprising: switching the drill rod disassembly system of the open-pit drilling rig to a rod changing mode; the control module cutting off the connection between the first operating key and the lower disassembly platform; controlling the lower disassembly platform to perform a clamping operation through the second operating key;

[0009] Furthermore, it also includes an upper drill rod, a pressure sensing module and a rotation module. After the lower disassembly platform is controlled to perform a clamping operation by the second operation key, it also includes: controlling the rotation module to be tightened with the upper drill rod; the pressure sensor determines whether the upper drill rod and the rotation module are tightened; if not, returning to the step: controlling the rotation module to be tightened with the upper drill rod; if so, controlling the lower disassembly platform to perform a loosening operation;

[0010] Furthermore, it also includes a judgment module and a re-clamping module. If so, after controlling the lower disassembly platform to perform the loosening operation, it also includes: lifting the lower drill rod to the position of the lower disassembly platform; controlling the lower disassembly platform to perform the clamping operation through the second operation key; the judgment module judges whether the lower disassembly platform clamps the lower drill rod; if so, controlling the rotation module to separate the upper drill rod from the lower drill rod; controlling the re-clamping module to clamp the upper drill rod, controlling the rotation module to separate from the upper drill rod and sending the upper drill rod into the drill rod warehouse, and treating the lower drill rod as a new upper drill rod; returning to the step of controlling the rotation module to tighten the upper drill rod; if not, controlling the re-clamping module to clamp the upper drill rod, and sending the upper drill rod into the drill rod warehouse.

[0011] The present invention discloses a drill rod disassembly system and method for an open-pit drilling rig, which specifically solves the technical problem that the drill rod is easy to drop when the ground open-pit drilling rig is changing the drill rod by improving the original rod changing mode. The following improvements are made relative to the original system design: after the machine is switched to the rod changing mode, the function of the lower disassembly platform opening control button must be invalid. Even if the operator presses the lower disassembly platform opening control button under subjective or non-subjective consciousness, the drill rod will not drop. Only when the lower disassembly platform locking control button is pressed and not released, the rotation movement that is necessary for disassembling the drill rod can occur. When the trolley is in the rod changing mode, the opening of the lower disassembly platform is automatically completed. When the drill head of the upper drill rod is screwed into the drill tail of the lower drill rod and rotated and locked to a stop, the lower disassembly platform begins to open to fully open. In this way, the pushing reciprocating action of the drill rod is carried out normally. When the machine exits the rod changing mode to the drilling mode, the locking and opening control buttons of the lower disassembly platform function normally; 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. This process is to prevent the rotating module from being re-tightened in the reverse direction due to misoperation when it is subsequently removed from the upper fiber rod, causing the lower drill clamp to open and the lower drill rod to fall into the rock drilling hole. The operator can manually control the locking and opening actions of the lower disassembly platform normally. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] If not, in S82, the re-clamping module is started, and a failure signal is transmitted to the pressure sensor, and the re-clamping module is controlled to clamp the upper drill rod, and the rotating module is controlled to disengage from the upper drill rod, and the upper drill rod is sent to the drill rod warehouse.

[0035] In embodiment 1 of the present invention, the drill rod disassembly system and method of the open-pit drilling rig include a control module, a lower disassembly platform, a first operating key, a second operating key, an upper drill rod, a pressure sensing module, a rotation module, a judgment module, a re-clamping module and a mode switching module; the lower disassembly platform is used to lock and / or release the lower drill rod; the drill rod disassembly system includes a rock drilling mode and a rod changing mode; when the drill rod disassembly system is in the rock drilling mode, the first operating key is used to control the lower disassembly platform to perform a loosening operation, and the second operating key is used to control the lower disassembly platform to perform a clamping operation; when the drill rod disassembly system is in the rod changing mode, the control module is used to cut off the connection between the first operating key and the lower disassembly platform; at this time, the first operating key cannot control the lower disassembly platform to perform a loosening operation.

When the drill rod disassembly system is in the rod changing mode, the pressure sensing module is used to determine whether the upper drill rod is tightened with the rotating module. If so, the lower disassembly platform is controlled to perform the loosening operation; the rotating module is used to control the tightening with the upper drill rod; the rotating module includes a rotating main valve, a rotating motor and a rotating head; and also includes a third relay and a four-way solenoid valve. The third relay is electrically connected to the second relay, and the third relay is electrically connected to the four-way solenoid valve. When the drill rod disassembly system is in the rod changing mode, the control module triggers the third relay by turning on the second relay, so that the power is input to the four-way solenoid valve to be powered, thereby disconnecting the rotating module. When the second operation key is pressed, the second relay is disconnected, and the second relay cannot be turned on and trigger the third relay. Therefore, the four-way solenoid valve cannot be powered and fails, so the rotating module is not disconnected.

[0052] If not, the re-clamping module is controlled to clamp the upper drill rod and send the upper drill rod into the drill rod warehouse. When the upper and lower drill rods are separated, the re-clamping solenoid valve is energized and transmits a failure signal to the pressure sensing module, indicating that the pressure sensing module fails. The re-clamping solenoid valve clamps and fixes the upper drill rod, and the rotating module is detached from the upper end of the upper drill rod by spinning, and the re-clamping solenoid valve puts the upper drill rod into the drill rod warehouse. After the rod is put into the warehouse, the re-clamping solenoid valve loses power and transmits a restart signal to the pressure sensing module, and the pressure sensing module restarts.
