Description

Technical Field

[0001] This utility model relates to the field of exploration equipment technology, and more specifically to an adjustable guardrail, a pole-changing system including the adjustable guardrail, and an exploration drilling rig. Background Technology

[0002] The drilling rig is equipped with a rod-changing system to connect and disconnect drill rods, which can greatly improve the safety of the rod connection and disconnection process and reduce the labor intensity of workers, making it an increasingly preferred choice in the exploration drilling industry.

[0003] When an exploration drilling rig is not equipped with a rod-changing system, the guardrail is usually small, only needing to protect the rotating head and one other moving part. However, when an exploration drilling rig is equipped with a rod-changing system, the thread-breaking manipulator is fixed to the tower and swings to different positions via hydraulic cylinders. The operator's platform is located on one side of the tower, close to the thread-breaking manipulator, necessitating a guardrail to protect the manipulator and prevent operators from accidentally entering the moving area and sustaining injury. In short, with a rod-changing system, the moving parts of the thread-breaking manipulator need comprehensive protection, significantly increasing the protected area.

[0004] The inventors discovered that after traditional guardrails protect the threaded manipulator, the guardrails need to be removed when the exploration drilling rig is being transported or moving to prevent interference with other components (such as the hood and hydraulic tank) and to allow the tower to be lowered smoothly. This process is time-consuming, labor-intensive, and extremely inefficient.

[0005] Therefore, it is urgent to solve the interference problem that may occur during the transportation of exploration drilling rigs due to the increased area of ​​the guardrail after the installation of the rod replacement system. Utility Model Content

[0038] To enable those skilled in the art to better understand this technical solution, the technical solution of this utility model will be clearly and completely described below in conjunction with the accompanying drawings and embodiments.

Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, provided they do not affect the effectiveness or purpose of this invention, should still fall within the scope of the disclosed technical content. Furthermore, terms such as "upper end," "one side," "above," "first," "second," and "third" used in this specification are merely for clarity and not intended to limit the scope of implementation.

[0040] With the current exploration drilling rig equipped with a rod changing system, the protective area of ​​the thread-connecting manipulator 3 will be increased. Therefore, after the operation is completed, the protective railing must be removed before the drilling rig is transported or moved. Otherwise, the protective railing may interfere with other components such as the hood and hydraulic oil tank, making it difficult for the tower to be lowered smoothly, which is time-consuming, labor-intensive, and reduces work efficiency.

[0041] The basic idea of ​​this utility model is to design an adjustable guardrail when the exploration drilling rig is equipped with a rod changing system. When the exploration drilling rig is working, the adjustable guardrail can be extended to provide a large protective area that can meet the protection needs of the operators. When the exploration drilling rig is finished, the adjustable guardrail can be reduced to reduce the protective area so that the guardrail will not interfere with other components such as the machine cover and hydraulic oil tank, thereby reducing labor intensity and improving work efficiency.

[0042] refer to Figures 1 to 5As shown in the figure, an adjustable guardrail of this utility model is used in the rod changing system of an exploration drilling rig, including a fixed part 11 and an adjustable part 12. The fixed part 11 is installed and fixed on the tower 4 of the exploration drilling rig. The fixing method can be welding, screwing, riveting, or other fixing methods, which are not limited here and can be selected individually or in combination as needed. The adjustable part 12 is configured such that when the exploration drilling rig is in working state, the adjustable part 12 is located above the fixed part 11 and is rigidly connected to the fixed part 11, that is, when the exploration drilling rig is in working state, the adjustable part 12 is connected to the fixed part 11. As a whole, it hardly shifts or deforms when subjected to external forces, thus providing protection. When the exploration drilling rig is in transport mode, at least a portion of the adjustable part 12 overlaps with the fixed part 11. That is, when the exploration drilling rig is in transport or moving mode, the adjustable part 12 can be adjusted, such as by extension, retraction, or folding, so that at least a portion, preferably all, of the adjustable part 12 overlaps with the fixed part 11. The so-called overlap means that the adjustable part 12 and the fixed part 11 coincide, reducing the space occupied by the adjustable part 12 alone, so that the guardrail will not interfere with other components such as the machine cover and hydraulic oil tank.

[0043] In some embodiments, the fixing part 11 includes a first fixing part 111, a second fixing part 112, and a third fixing part 113. The first fixing part 111 is fixedly installed on the tower 4, the second fixing part 112 is fixedly connected to the first fixing part 111, and the third fixing part 113 is fixedly connected to the tower 4. One side of the third fixing part 113 is movably connected to one side of the adjustable part 12.

[0044] When the exploration drilling rig is in operation, the adjustable part 12 is located above the second fixed part 112. The adjustable part 12, the second fixed part 112, and the third fixed part 113 are located in the same plane, and the protective area is as large as possible to meet the protection needs of the operators. When the exploration drilling rig is in transport mode, the adjustable part 12 can be folded onto the third fixed part 113, that is, the adjustable part 12 and the third fixed part 113 overlap. The adjustable part 12 reduces the space occupied by it alone and avoids the guardrail from interfering with other components.

[0045] Furthermore, the adjustable part 12 includes a first adjustable part 121 and a second adjustable part 122. The second adjustable part 122 is movably connected to the third fixed part 113. The first adjustable part 121 is rotatably connected relative to the second adjustable part 122 about the upper end of the second adjustable part 122.

[0046] When the exploration drilling rig is in operation, the first adjustable part 121 is located above the second adjustable part 122 and is rigidly connected to the second adjustable part 122, that is, the first adjustable part 121 and the second adjustable part 122 are connected as one unit, further increasing the protective area of ​​the guardrail. When the exploration drilling rig is in transport mode, the first adjustable part 121 can be rotatably folded over the second adjustable part 122. The first adjustable part 121 can rotate around the upper end of the second adjustable part 122 as an axis and fit together with the second adjustable part. Then, the second adjustable part 122 rotates and folds around one side as an axis over the third fixed part 113. At this time, the first adjustable part 121, the second adjustable part 122 and the third fixed part 113 overlap, further compressing the space occupied, so that the adjustable guardrail will not interfere with other components.

[0047] Preferably, the first adjustable part 121 is connected to the second adjustable part 122 via a latch 14. When the exploration drilling rig is working, the first adjustable part 121 and the second adjustable part 122 are latched together to form a rigid whole and jointly play a protective role; when the exploration drilling rig is in transport mode, the latch 14 is disengaged from the first adjustable part 121 and the second adjustable part 122, and the first adjustable part 121 is folded into the second adjustable part 122.

[0048] A spring pin 15 is installed on one side of the third fixing part 113, and a pin hole 16 is provided at a corresponding position of the first adjustable part 121. When the exploration drilling rig is in transport mode, the spring pin 15 can be inserted into the pin hole 16 to fix the first adjustable part 121 and the second adjustable part 122. In this way, the adjustable guardrail is more stable and less prone to shaking during the transportation of the exploration drilling rig.

[0049] The second adjustable part 122 is movably connected to the third fixed part 113 via a hinge 13. Of course, other movable connection methods can also be used to connect the second adjustable part 122 and the third fixed part 113. This is not limited here and can be selected according to actual needs.

[0050] In some embodiments, the fixing part 11 includes a first fixing part 111 and a second fixing part 112, wherein the first fixing part 111 is fixedly mounted on the tower 4, and the second fixing part 112 is fixedly connected to the first fixing part 111.

[0051] When the exploration drilling rig is in operation, the adjustable part 12 is located above the second fixed part 112 and is rigidly connected to the second fixed part 112. When the exploration drilling rig is in transport mode, at least a portion of the adjustable part 12 can be accommodated within the second fixed part 112. If the second fixed part 112 is box-shaped with an internal cavity to accommodate the adjustable part 12, when the exploration drilling rig is in operation, the adjustable part 12 extends upward from the cavity inside the second fixed part 112, expanding the protective area of ​​the guardrail to meet the protection needs of the operator. When the exploration drilling rig is not in operation, the adjustable part 12 can retract into the cavity inside the second fixed part 112 to reduce the protective area of ​​the guardrail and prevent interference between the guardrail and other components. The extension and retraction can be achieved using a linkage mechanism or springs, similar techniques already used in existing technologies and will not be detailed here. Based on this, automatic control technology can also be introduced to control the adjustable part 12 to rise and fall automatically, which can further improve work efficiency. As for the implementation method, it has been applied in the existing technology, and will not be described in detail here.

[0052] Preferably, the adjustable part 12 includes a first adjustable part 121 and a second adjustable part 122;

[0053] When the exploration drilling rig is in operation, the second adjustable part 122 is located above the second fixed part 112 and rigidly connected to the second fixed part 112, and the first adjustable part 121 is located above the second adjustable part 122 and rigidly connected to the second adjustable part 122. When the exploration drilling rig is in transport mode, the second adjustable part 122 can be at least partially accommodated in the second fixed part 112, and the first adjustable part 121 can be at least partially accommodated in the second adjustable part 122. A more preferred arrangement is that the second fixed part 112 just completely accommodates the second adjustable part 122, and the second adjustable part 122 just accommodates the first adjustable part 121. In this arrangement, the protective area of ​​the guardrail is maximized when extended and minimized when retracted, better meeting the protection needs of operators while minimizing interference between the guardrail and other components.

[0054] This utility model also relates to a rod changing system, including the aforementioned adjustable guardrail. While achieving efficient connection and disconnection of drill rods, it can effectively protect the safety of operators and ensure that the guardrail does not interfere with other components, thereby improving rod changing efficiency.

[0055] Finally, this utility model also relates to an exploration drilling rig, including the aforementioned rod changing system.

[0056] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. If any person skilled in the art, inspired by this description, designs a similar structure to the present invention without departing from its inventive spirit, such design shall fall within the protection scope of the present invention.
