Description

Technical Field

[0001] This utility model relates to the field of mechanical technology for oil drilling engineering, and in particular to a multi-directional adjustment device for a steel driller and a steel driller. Background Technology

[0002] Iron drills are key pipe handling equipment in modern oil and gas drilling operations, widely used for attaching and detaching drill pipes, casings, and other tubing strings, directly impacting drilling efficiency and operational safety. With the development of drilling equipment towards miniaturization, modularization, and high mobility, such as the widespread use of small drilling rigs, trailer-mounted drilling rigs, and vehicle-mounted drilling rigs, existing iron drills face numerous technical challenges in terms of structural layout and functional adaptability.

[0003] In terms of height, miniature drilling rigs often use mast-type derricks with relatively low crossbeam heights. When equipped with a top drive system, the sag of components such as the water hose and cables is significant, easily causing spatial interference with the metal drill bit. The traditional metal drill bit's standby position and rotation require considerable vertical space, severely limiting its installation and operation in low-profile derrick environments. Furthermore, when the existing metal drill bit's lifting mechanism malfunctions, the limited space on the drilling platform and restricted lifting conditions make disassembly and replacement of critical components extremely difficult, increasing maintenance costs and downtime. On the other hand, the relatively high overall height also prevents it from fitting into standard-height containers during land or sea transport, significantly increasing transportation costs. Regarding horizontal spatial layout, miniature drilling rig derricks have narrow projected areas and small spacing between the columns on both sides. When the metal drill bit needs to be installed inside the derrick columns, the traditional telescopic boom structure positioned between the columns and the working tongs results in overlapping projected volumes, interfering with the derrick columns and limiting its rotational working range.

[0004] The tool handling unit of a steel driller must always be perpendicular to the drill pipe axis, i.e., in a horizontal position. If the tilt angle is too large, the contact area between the jaws or leveling rollers and the drill pipe will decrease, easily scratching the tool surface, damaging the jaws, and significantly reducing the efficiency of threading and unthreading. Currently, common leveling devices are usually installed between the telescopic boom and the tool handling unit. This structure not only increases the overall projected volume of the machine, causing layout redundancy, but also suffers from cumbersome adjustment operations and slow response speeds, making it difficult to meet the demands of efficient drilling operations.

[0019] (III) Beneficial Effects

[0020] The beneficial effects of this utility model are:

[0021] This utility model discloses a multi-directional adjustment device and a drill bit for pipe handling. Through the coordinated operation of a lifting and rotating mechanism, a telescopic mechanism, a C-frame, and adjustment components, it achieves flexible and precise adjustment of the pipe handling device in multiple directions. This utility model has a simple overall structure, uses few parts, and has low manufacturing, maintenance, and transportation costs.

[0022] The telescopic mechanism adopts a configuration in which the first telescopic component, the connecting component, and the second telescopic component are connected in series and rotated along the length direction, and are driven by an independent telescopic drive component. This structural design is extremely compact. In the fully retracted state, each component can be tightly folded, significantly reducing the structural volume and overall height of the entire iron drilling equipment, while greatly reducing the projected area of ​​the equipment on the platform, which is beneficial for the layout of drilling platforms with limited space.

[0023] The lifting and rotating mechanism adopts a low-profile integrated design, which effectively reduces the overall height and center of gravity of the equipment. This not only reduces the overall size of the equipment, but also significantly reduces the difficulty of on-site installation and disassembly, as well as the complexity of subsequent maintenance.

[0024] The adjustment component is hinged to the front end of the telescopic mechanism, allowing for convenient adjustment of the C-frame's pitch angle. Operation is simple and adjustment is easy. When retracted in conjunction with the telescopic mechanism, the adjustment component ensures the C-frame fits snugly against the side of the lifting and rotating device, further reducing the equipment's storage space and minimizing its footprint when not in operation.

[0038] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0039] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention can be understood more clearly and thoroughly, and that the scope of the present invention can be fully conveyed to those skilled in the art.

[0040] Example 1:

[0041] like Figure 1As shown, this embodiment provides a multi-directional adjustment device for a drill bit operator, including a lifting and rotating mechanism 1, a telescopic mechanism 2, a C-frame 3, and an adjustment assembly 4 connected to the top of the C-frame 3. The telescopic mechanism 2 includes a first telescopic assembly 21, a connecting assembly 22, a second telescopic assembly 23, and a telescopic drive assembly 24, all hinged sequentially along its length. The first end of the first telescopic assembly 21 is hinged to the adjustment assembly 4, the first end of the telescopic drive assembly 24 is hinged to the first telescopic assembly 21, and the second ends of both the second telescopic assembly 23 and the telescopic drive assembly 24 are hinged to the lifting and rotating mechanism 1. A pipe handling device 5 is mounted on the C-frame 3. The lifting and rotating mechanism 1 drives the telescopic mechanism 2 to vertically lift and rotate, and the telescopic drive assembly 24 drives the first telescopic assembly 21 and the second telescopic assembly 23 to unfold or retract, adjusting the distance between the C-frame 3 and the lifting and rotating mechanism 1 so that the pipe handling device 5 can move to the drill bit position. The adjustment assembly 4 is used to adjust the horizontal angle of the pipe handling device 5. Through the coordinated operation of the lifting and rotating mechanism 1, the telescopic mechanism 2, the C-shaped frame 3, and the adjustment component 4, the pipe handling device 5 achieves flexible and precise adjustment in multiple directions. This utility model has a simple overall structure, uses few parts, and has low manufacturing, maintenance, and transportation costs.

[0042] like Figure 5 As shown, the adjustment assembly 4 includes an adjustment frame 41, two connecting frames 42, two connecting pins 43, and two adjusting pins 44. A C-shaped frame 3 is located inside the adjustment frame 41, and the two connecting frames 42 are symmetrically arranged on the outside of the adjustment frame 41. One end of the C-shaped frame 3, the adjustment frame 41, and the connecting frames 42 are coaxially rotatably connected by connecting pins 43, and the other end of the adjustment frame 41 and the connecting frame 42 are connected by adjusting pins 44. The two symmetrically arranged connecting frames 42, connecting pins 43, and adjusting pins 44, together with the adjustment frame 41 and the C-shaped frame 3, form a stable rigid frame with dual-sided synchronous drive. Figure 3 As shown, the first end of the first telescopic assembly 21 is hinged to both connecting pins 43 and two adjusting pins 44. Rotating the adjusting pins 44 drives the adjusting frame 41 to move relative to the connecting frame 42, thereby causing the C-frame 3 to rotate around the axis of the connecting pins 43 to adjust its angle. The adjusting assembly 4 is hinged to the front end of the telescopic mechanism 2, allowing for convenient adjustment of the pitch angle of the C-frame 3. Operation is simple and adjustment is convenient. Furthermore, the entire adjusting assembly 4 is embedded between the C-frame 3 and the first telescopic assembly 21, without adding a bulky external mechanism, minimizing space occupation in height and projection plane, avoiding interference with the derrick and other wellhead equipment, and meeting the stringent size requirements of compact drilling rigs.

[0043] Preferably, the adjusting pin 44 is designed as an eccentric shaft. Rotating the adjusting pin 44 precisely drives the adjusting frame 41 to produce displacement, which in turn drives the C-shaped frame 3 to rotate around the axis of the connecting pin 43, realizing the fine adjustment function of the horizontal clamping angle of the pipe handling device 5. This ensures that the jaws or rollers maintain the maximum contact area with the drill pipe during operation, effectively avoiding problems such as jaw slippage and drill pipe surface damage caused by excessive tilt angle. This protects the pipe, extends the jaw life, and improves the success rate and efficiency of coupling and uncoupling.

[0044] like Figure 3 and Figure 4 As shown, the first telescopic assembly 21 includes a connecting rod 211, two first telescopic arms 212, and two first pull rods 213. The two first telescopic arms 212 and the two first pull rods 213 are spaced apart and opposite to each other, with the two first telescopic arms 212 fixedly connected by the connecting rod 211. The first ends of the two first pull rods 213 are respectively hinged to two connecting pins 43, and the first ends of the two first telescopic arms 212 are respectively hinged to two adjusting pins 44. The first end of the telescopic drive assembly 24 is hinged to the connecting rod 211, and the second end is hinged to the lifting and rotating mechanism 1. The second telescopic assembly 23 includes two second telescopic arms 231 and two second pull rods 232, which are spaced apart and opposite to each other. The two first telescopic arms 212 and the two first pull rods 213 form a short parallelogram linkage structure, while the two second telescopic arms 231 and the two second pull rods 232 form a long parallelogram linkage structure. The short parallelogram linkage structure and the long parallelogram linkage structure provide a large horizontal extension stroke while strictly constraining the movement trajectory of the C-frame 3, ensuring that it maintains horizontal translation throughout the entire movement process without attitude drift or warping. This guarantees that the pipe handling device 5 can still be precisely aligned with the drill pipe after long-distance movement, greatly improving the positioning accuracy and success rate of the upper and lower couplings.

[0045] like Figure 3 and Figure 4As shown, the connecting assembly 22 includes a top plate 221, two connecting plates 222, and two trapezoidal connectors 223. The two trapezoidal connectors 223 are symmetrically arranged, with the top plate 221 fixedly connected to the tops of the two trapezoidal connectors 223. The two connecting plates 222 are respectively disposed inside the two trapezoidal connectors 223. The second end of the first telescopic arm 212 and the first end of the second telescopic arm 231 are hinged to the connecting plates 222. The second end of the first telescopic arm 212 and the second end of the first tie rod 213 are both hinged to the trapezoidal connectors 223. The first end of the second tie rod 232 and the middle end of the second telescopic arm 231 are both hinged to the trapezoidal connectors 223. The second end of the second telescopic arm 231 and the second end of the second tie rod 232 are both hinged to the lifting and rotating mechanism 1. This structural design is extremely compact. In the fully retracted state, all components can be tightly folded, significantly reducing the structural volume and overall height of the entire iron drilling equipment, while also greatly reducing the projected area of ​​the equipment on the platform, which is beneficial for layout on space-constrained drilling platforms.

[0046] like Figure 4 As shown, the telescopic drive assembly 24 includes two symmetrically arranged telescopic cylinders 241. The first end of each of the two telescopic cylinders 241 is hinged to the connecting rod 211, and the second end of each is hinged to the lifting and rotating mechanism 1.

[0047] Preferably, the ratio of the piston rod stroke of the telescopic cylinder 241 to the horizontal telescopic stroke of the C-frame 3 is 1:1.3, significantly expanding the working coverage of the pliers. This allows the driller to effectively reach and handle pipes at greater distances while minimizing the projected volume of his own structure.

[0048] Preferably, the telescopic mechanism 2 further includes a guardrail 25, which can be plugged into and fixed to the top of the top plate 221 to protect the control box of the telescopic mechanism 2.

[0049] To achieve precise positioning with multiple degrees of freedom and improve spatial adaptability, such as Figure 6As shown, the lifting and rotating mechanism 1 includes a column 11, a rotating assembly 12, and a lifting assembly 13. The column 11 is fixedly installed above the rotating assembly 12, which drives the column 11 to rotate horizontally. The lifting assembly 13 is slidably mounted on the column 11 and can move vertically up and down along the axis of the column 11. The second end of the telescopic drive assembly 24 and the second end of the second telescopic assembly 23 are both hinged to the lifting assembly 13. Through the horizontal rotation driven by the rotating assembly 12, the vertical lifting driven by the lifting assembly 13, and the cooperation with the telescopic mechanism 2, the end-capsule handling device 5 can move flexibly in three-dimensional space. This layout is particularly suitable for compact drilling rigs such as trailer-mounted drilling rigs and truck-mounted drilling rigs with small derrick projection areas and height restrictions imposed by top drive equipment. It can effectively avoid interference from obstacles such as derrick columns and top drive hoses, and accurately position itself to the working position. The lifting and rotating mechanism 1 adopts a low-profile integrated design, which effectively reduces the overall height and center of gravity of the equipment. This not only reduces the overall volume of the equipment, but also significantly reduces the difficulty of on-site installation and disassembly, as well as the complexity of subsequent maintenance work.

[0050] Furthermore, such as Figure 6 As shown, the lifting assembly 13 includes a lifting trolley 131, a lifting cylinder 132, and a lifting cylinder support 133. The lifting trolley 131 is slidably mounted on the column 11, and the lifting trolley 131 is detachably connected to the lifting cylinder support 133. The piston rod end of the lifting cylinder 132 is fixedly connected to the lifting cylinder support 133, and the cylinder body end of the lifting cylinder 132 is mounted on a rotary mechanism. The extension and retraction movement of the lifting cylinder 132 drives the lifting cylinder support 133 to rise and fall, thereby causing the lifting trolley 131 to rise and fall along the column 11. The lifting cylinder 132 indirectly drives the lifting trolley 131 by pushing the lifting cylinder support 133, converting the main pushing and pulling force into the smooth movement of the trolley along the sturdy column. Since the lifting trolley 131 and the lifting cylinder support 133 are detachably connected, when the lifting cylinder 132 or related components need to be repaired or replaced, the cylinder and internal pipeline cables can be installed and disassembled without separating the column 11 and the lifting trolley 131. This greatly facilitates maintenance operations and solves the problems of difficult maintenance of the lifting assembly 13 and high-altitude hoisting.

[0051] The second end of the telescopic cylinder 241, the second telescopic arm 231, and the second end of the second pull rod 232 are all hinged to the lifting trolley 131.

[0052] Preferably, the lifting cylinder 132 is a two-stage hydraulic cylinder with a short length and a long stroke, which further solves the problem of the lifting assembly 13 occupying a large vertical space.

[0053] Preferably, the lifting trolley 131 includes multiple composite rollers, which are distributed on the inner side of the lifting trolley 131 and are slidably disposed in the guide rail of the column 11.

[0054] like Figure 6 As shown, the rotary assembly 12 includes a rotary base 121 and a rotary drive 122. The column 11 is fixedly mounted on the rotary base 121, and the rotary drive 122 is located on one side of the rotary base 121 and is connected to it for transmission. The rotary drive 122 drives the rotary base 121 and the column 11 fixed thereon to rotate around a vertical axis in a horizontal plane.

[0055] like Figure 2 As shown, when the telescopic mechanism 2 is in the fully retracted state, the top plate 221 of the connecting assembly 22 is located directly above the column 11, and the side wall of the C-shaped frame 3 is in contact with the outer surface of the second telescopic arm 231 of the second telescopic assembly 23. When the multi-directional adjustment device retracts, the C-shaped frame 3 can be tightly attached to the side of the lifting and rotating mechanism 1, further compressing the storage space of the equipment and reducing the floor space occupied in the non-working state.

[0056] Example 2:

[0057] like Figure 1 and Figure 2 As shown, this embodiment provides a steel drill, which includes the multi-directional adjustment device for the steel drill in embodiment 1 and the pipe handling device 5 installed on the C-frame 3.

[0058] like Figure 1 As shown, the pipe handling device 5 includes a screw fastening mechanism 51 and a punching mechanism 52. The screw fastening mechanism 51 is slidably connected to the top of the C-shaped frame 3, and the punching mechanism 52 is installed on the inner side of the C-shaped frame 3.

[0059] like Figure 1 As shown, the iron drill also includes a mounting base, and the bottom of the rotating base 121 is fixedly mounted on the mounting base 6 by multiple fasteners.

[0060] Preferably, such as Figure 2 As shown, when the telescopic mechanism 2 is in the fully retracted state, the projected outline of the iron drill is completely within the projection range of the mounting base 6.
