Description

Technical Field

[0001] This utility model relates to the field of coal mine drilling rig technology, specifically to a direct-rotation drill rod conveying device. Background Technology

[0002] A coal mine drilling rig is a drilling device used in the field of coal mining. It has both drilling and hole enlargement functions and is an important piece of equipment to ensure the safety of coal mining and geological exploration.

[0003] Existing automatic mining drilling rigs mostly employ a drill rod conveying system combining dual manipulators and drill rod boxes. For example, Chinese invention patent CN110952972B discloses a coal mine drilling rig and its control method. This system increases the onboard drill rod storage capacity, allowing for continuous operation of the drilling rig for extended periods. However, the existing drill rod conveying mechanism involves numerous movements and complex processes, resulting in low efficiency in drill rod conveying and overall construction. Furthermore, the relative positions of the main manipulator with the drilling rig host and conveyor cause interference between the manipulator and the tracked vehicle or conveyor when conveying drill rods under large negative inclination angles, preventing automatic drill rod delivery.

[0004] Chinese utility model patent CN219299240U discloses a drill rod loading and unloading device and a tunnel drilling rig, including a drilling rig main unit, a mounting base, a through hole for the drill rod to pass through, and a loading and unloading mechanism connected to the mounting base. The loading and unloading mechanism includes a clamping component, a rotating component, and a telescopic component. The clamping component clamps the drill rod, and the rotating component is connected to the clamping component and drives the clamping component to rotate. The drill rod loading and unloading mechanism and the drill rod conveying mechanism are respectively connected to both sides of the mounting base. The conveying mechanism transmits the drill rod, perpendicular to the drill rod axis of the frame, to the loading and unloading mechanism through the through hole on the mounting base. The loading and unloading mechanism clamps the drill rod and rotates it until the drill rod coincides with the axis of the frame, thus completing the drill rod conveying. This technology still suffers from problems related to the complexity of the conveying route and mechanism. Utility Model Content

[0005] The present invention aims to provide a direct-rotation drill pipe conveying device to simplify the drill pipe conveying route.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a direct-rotation drill rod conveying device, comprising a drill rod box and a transfer mechanism, wherein the drill rod in the drill rod box is arranged parallel to the frame, and the transfer mechanism includes a moving unit located on the side of the drill rod box perpendicular to the frame, wherein a lifting unit is mounted on the moving unit, and a telescopic gripping unit for gripping the drill rod is provided on the lifting unit, wherein the moving unit can drive the telescopic gripping unit to move toward the frame, and the telescopic gripping unit is provided with a rotary drive component, which can drive the drill rod to be perpendicular to the frame.

[0007] The beneficial effects of this solution are as follows: The process for removing and transporting drill rods from the drill rod box is as follows:

[0008] (1) Initial setting: A certain number of drill rods are stored in the drill rod box. At this time, the telescopic gripping unit is located above the drill rod box and is in the initial ready-to-work state.

[0009] (2) Positioning and column selection: The telescopic gripping unit is driven by the moving unit to move along the axis perpendicular to the drill rod in the drill rod box, thereby determining the specific column of drill rod in the drill rod box and preparing for the subsequent gripping operation.

[0010] (3) Height adjustment: The lifting unit is then started, and in conjunction with the adjustment function of the telescopic gripping unit itself, the two work together to gradually adjust the height of the telescopic gripping unit with the minimum height movement until it accurately reaches the height value suitable for gripping the drill rod, thus creating favorable height conditions for successfully gripping the drill rod.

[0011] (4) Grab the drill rod: After the height is adjusted to the correct position, control the telescopic gripping unit to perform the clamping action and firmly grip the drill rod.

[0012] (5) Height adaptation: Relying on the joint cooperation of the lifting unit and the telescopic gripping unit, the height of the telescopic gripping unit is carefully adjusted so that it and the drill rod being gripped are adjusted to a specific height that meets the requirements of drill rod transportation, ensuring that the drill rod can move smoothly and steadily during subsequent transportation.

[0013] (6) Rotate the drill rod: Start the rotary drive, which controls the telescopic gripping unit to rotate, rotating the drill rod from a direction parallel to the frame to a direction perpendicular to the frame.

[0014] (7) Drill rod placement: The moving unit drives the telescopic gripping unit to move stably along the axis perpendicular to the drill rod inside the drill rod box in a direction away from the drill rod box, accurately delivering the drill rod to the location of the drilling mechanism, thus completing the drill rod delivery task. Afterwards, the angle of the drill rod is changed by the flipping manipulator to keep it parallel to the frame, facilitating subsequent drill rod connection operations.
