Description

Technical Field

[0001] This utility model relates to the field of coal mine drilling rig technology, specifically to a rectangular coordinate type drill rod transfer device. Background Technology

[0002] In the underground working environment of coal mines, drilling plays a crucial role in the coal mining operation chain. As the core equipment for performing drilling tasks, the performance of drilling rigs is undoubtedly a key factor determining construction efficiency and quality. With the continuous advancement of coal mining technology, the requirements for drilling rigs in terms of automation and work efficiency are becoming increasingly stringent.

[0003] As an indispensable key component of drilling rigs, the drill pipe transfer device plays a crucial pivotal role in the entire drilling process, and its performance directly affects the continuity and stability of the operation. Currently, the drill pipe transfer devices commonly used in the industry are mostly based on the technical solution disclosed in patent number CN110952972B. In this solution, the drill pipe is placed parallel to the frame inside the drill pipe box. The drill pipe is transported to the frame for easy installation through the coordinated operation of the rod delivery manipulator on the side of the drill pipe box, the drill pipe transfer device between the drill pipe box and the frame, and the main manipulator between the drill pipe transfer device and the frame. However, this solution has significant drawbacks. In terms of structural complexity, it relies on the coordinated operation of the rod delivery manipulator, the drill pipe transfer device, and subsequent conveying devices to achieve drill pipe transfer, which makes the system complex and difficult to coordinate. In terms of space utilization, the drill pipe transfer device increases the overall length of the drilling rig, which, in the limited downhole working space, squeezes the layout space of other equipment, hinders the passage of personnel and materials, reduces operating efficiency, and may also cause safety hazards such as equipment collisions and personnel not being able to avoid them.

[0004] In summary, existing drill pipe transfer devices can no longer meet the demands of efficient, safe, and convenient drill pipe transfer in underground coal mining operations. There is an urgent need for a new drill pipe transfer device to solve these problems and promote the development of coal mining technology. Utility Model Content

[0005] This utility model aims to provide a rectangular coordinate type drill pipe transfer device to overcome the problems of complex structure, low space utilization and safety hazards of existing drill pipe transfer devices, so as to realize efficient, safe and convenient transfer of drill pipes in coal mines, thereby better meeting the needs of coal mining operations and promoting the progress of coal mining technology.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a rectangular coordinate type drill pipe transfer device, comprising a first moving unit, which is located on the side of the drill pipe box near the frame and can slide along the axis perpendicular to the drill pipe inside the drill pipe box; a lifting unit is installed on the first moving unit, and a second moving unit is installed on the top of the lifting unit, which can drive the second moving unit to perform lifting and lowering actions, and the second moving unit can move along the axis of the drill pipe inside the drill pipe box; a telescopic gripping unit for gripping the drill pipe is installed on the second moving unit.

[0007] The beneficial effects of this solution are as follows: The transfer process for removing the drill pipe from the drill pipe box is as follows:

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

[0009] (2) The telescopic gripping unit is driven by the first 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) After the column selection is completed, the telescopic grabbing unit is driven by the second moving unit to move along the axial direction of the drill rod in the drill rod box until the telescopic grabbing unit reaches the middle position of the drill rod in the drill rod box, so as to ensure that the grabbing action can be carried out in a suitable lateral position.

[0011] (4) The lifting unit is then started, and in conjunction with the adjustment function of the telescopic gripping unit, the two work together to gradually adjust the height of the telescopic gripping unit until it accurately reaches the appropriate height value for gripping the drill rod, thus creating favorable height conditions for successfully gripping the drill rod.

[0012] (5) Once the height is adjusted to the correct position, the telescopic gripping unit performs a clamping action to firmly grip the drill pipe. Afterward, the height of the telescopic gripping unit is raised again through the combined adjustment of the lifting unit and the telescopic gripping unit, bringing it to the position above the drill pipe box.

[0013] (6) Through the joint cooperation of the No. 1 moving unit, the No. 2 moving unit, the lifting unit and the telescopic gripping unit, the drill rod is transported to the location of the drilling mechanism. Then, the angle of the drill rod is changed by the flipping manipulator to keep it parallel to the frame, which provides convenient conditions for the subsequent connection operation of the drill rod.

[0014] Compared with existing technologies, this technical solution has the following advantages:

[0015] This technical solution cleverly combines the No. 1 moving unit, the lifting unit, the No. 2 moving unit, and the telescopic gripping unit, eliminating the complex transfer device structure and reducing the intricate inter-component linkages, resulting in a simpler and more compact overall structure. This simplified structure not only reduces manufacturing and maintenance costs but also minimizes the risk of failure caused by complex structures, improving the reliability and stability of the device and providing strong support for long-term, high-intensity operations in coal mines.

[0016] In this technical solution, each unit can move flexibly in both vertical and horizontal directions without the need for additional large transfer components, resulting in a small footprint and more efficient use of limited underground space. Operators have more spacious operating space during operations, and material transportation is smoother, effectively avoiding the risk of collisions between equipment, improving the safety and efficiency of the entire work area, and better meeting the needs of the complex and confined working environment in coal mines.

[0017] This technical solution, through the ingenious combination of the lifting unit and the telescopic gripping unit, allows for smooth switching between high and low positions of the telescopic gripping unit through their coordinated operation. In complex working environments such as narrow-section roadways, this design effectively reduces the stringent requirements on the height of the work site, greatly expanding the application range of the device in special working environments.

[0018] Thanks to the inclusion of the second moving unit, this technical solution can precisely drive the telescopic gripping unit to move axially along the drill rod within the drill rod box. Regardless of the drill rod's size, it ensures the telescopic gripping unit is stably clamped at the center or center of gravity of the drill rod. This effectively maintains the drill rod's balance during transport, preventing swaying and misalignment caused by uneven force, significantly improving the stability and reliability of drill rod transport. This provides precise drill rod positioning conditions for subsequent drilling operations, thereby enhancing construction quality.

Two connecting blocks 9 with snap-fit ​​grooves are bolted to the outer side of the outer lifting cylinder 6.

The first driving component 8 is bolted to the bottom of the outer lifting cylinder 6. The output shaft of the first driving component 8 extends into the interior of the outer lifting cylinder 6 and is bolted to the bottom of the inner lifting cylinder 7 or a second moving unit, thereby driving the second moving unit to lift.

[0037] like Figure 1 As shown, the second moving unit is located at the top of the lifting inner cylinder 7 and can move along the axial direction of the drill rod. Specifically, the second moving unit includes a crossbeam 11, a connecting bar 12, and a second power component 13.

[0042] (3) Lateral centering: Next, the second power unit 13 starts to operate, driving the moving seat 14 to move along the second gear guide, driving the clamping claw 17 to move synchronously until the clamping claw 17 reaches the top of the middle position of the drill rod in the drill rod box 1.

[0043] (4) Height adjustment: Subsequently, the clamping drive 20 controls the clamping claw 17 to release, and the height of the clamping claw 17 is adjusted by the coordinated action of the first drive 8 and the second drive 19 until it reaches a suitable height value for gripping the drill rod.

[0044] (5) Grab the drill rod: Then, the clamping drive 20 drives the clamping claw 17 to clamp the drill rod again. Then, the height of the clamping claw 17 is adjusted by the first drive 8 and the second drive 19 together, so that it rises to the position above the drill rod box 1.

[0045] (6) Drill rod delivery: Through the joint cooperation of the No. 1 moving unit, the No. 2 moving unit, the lifting unit and the telescopic gripping unit, the drill rod is delivered to the location of the drilling mechanism.
