Description

Technical Field

[0001] This invention relates to the field of transportation equipment technology, and more particularly to a drill pipe transfer device and a vessel. Background Technology

[0002] A drill pipe is a steel pipe with threads at the end, used to connect the surface equipment of the drilling rig to the drilling equipment or bottom hole device located at the bottom of the well. It is one of the common exploration tools in oil exploration. Its purpose is to transport drilling mud to the drill bit and raise, lower or rotate the bottom hole device together with the drill bit.

[0003] In related technologies, during oil exploration, existing methods typically involve using non-powered flatbed trucks to transport and hoist tools such as drill pipes to designated locations. During the transport process, the non-powered flatbed trucks are mainly pushed manually. This method is not only inefficient, but also requires manual labor or a crane to lift the trucks when they encounter steps or obstacles, further reducing transport efficiency and causing many inconveniences for oil exploration. Summary of the Invention

[0004] One objective of this invention is to provide a drill pipe transport device and vessel that can solve the problem of low transport efficiency of drill pipes and other tools due to the difficulty of existing unpowered flatbed vehicles in climbing steps or crossing obstacles.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A drill pipe transfer device includes a main frame and traveling wheels; the traveling wheels are in at least two sets and are spaced apart along the length of the main frame; each set of traveling wheels can be controlled independently, and each set of traveling wheels includes at least one lifting mechanism; the lifting mechanism includes a lifting bracket, a swing member, a pulley, a rolling drive member, and a telescopic drive member; the lifting bracket is connected to the main frame; one end of the swing member is rotatably connected to the lifting bracket, and the pulley is rotatably connected to the other end of the swing member; the rolling drive member includes a main body and an output part; the main body is connected to the swing member, and the output part is connected to the pulley, and the rolling drive member can drive the pulley to rotate relative to the swing member; the telescopic drive member includes a first component and a second component that can be telescopically extended relative to each other; the first component is rotatably connected to the lifting bracket, and the second component is rotatably connected to the swing member, and the telescopic drive member can drive the swing member to rotate relative to the lifting bracket, so that the pulley can reciprocate between positions close to and far from the main frame.

[0007] Optionally, the swing component includes two parallel swing plates; the two swing plates are connected by a first rotating shaft, the two ends of the first rotating shaft being rotatably connected to the two sides of the lifting bracket respectively; the second component is connected to a second rotating shaft, the two ends of the second rotating shaft being rotatably connected to the two swing plates respectively.

[0008] Optionally, it also includes a shelf and a flipping drive; at least one end of the shelf is detachably rotatably connected to the main frame; one end of the flipping drive is connected to the shelf and the other end is connected to the main frame; the flipping drive can drive the shelf to rotate relative to the main frame.

[0009] Optionally, the flipping drive includes two telescopic mechanisms, the first end of which is hinged to the shelf and the second end of which is hinged to the main frame; and the first ends of the two telescopic mechanisms are spaced apart along the length of the shelf and the second ends of the two telescopic mechanisms are spaced apart along the length of the main frame.

[0010] Optionally, a rotating engagement assembly is provided between the main frame and the shelf, the rotating engagement assembly including a mounting shaft and a mounting seat, the mounting seat being provided with a mounting groove having an assembly opening, the mounting shaft being mounted in the mounting groove through the assembly opening; the mounting shaft is rotatably connected to the shelf, and the mounting seat is connected to the main frame; or, the mounting shaft is rotatably connected to the main frame, and the mounting seat is connected to the shelf.

[0011] Optionally, the rotating engagement assembly is in two sets, with the two sets of rotating engagement assemblies respectively distributed at both ends of the main frame.

[0012] Optionally, the main frame is provided with a first clutch, which includes a first clutch head, a guide seat, a first piston rod, and a first hydraulic cylinder. The guide seat is connected to the main frame, the first hydraulic cylinder is connected to the guide seat, the first clutch head is movably disposed on the guide seat, the first piston rod connects the first hydraulic cylinder and the first clutch head, and the first clutch head is provided with a first limiting groove corresponding to the mounting shaft. The first hydraulic cylinder can drive the first clutch head to move in a direction close to the mounting shaft through the first piston rod, so that the end of the mounting shaft is located in the first limiting groove, thereby limiting the mounting shaft.

[0013] Optionally, the mounting base is provided with a second clutch, which includes a second clutch head, a fixed seat, a second piston rod, and a second hydraulic cylinder.

[0016] The beneficial effects of this invention are as follows: When encountering steps or obstacles, the lifting mechanism of the front traveling wheels can control the telescopic movement between the first and second components through the telescopic drive component, thereby driving the swing component and the pulleys set on the swing component to rotate relative to the lifting bracket. This ensures that the minimum height of the pulleys of the front traveling wheels is higher than the minimum height of the pulleys of the rear traveling wheels, enabling each set of traveling wheels to climb steps and cross obstacles. This allows the entire drill pipe transfer equipment to climb steps or cross obstacles without manual lifting or crane lifting. In addition, the rolling drive component can provide rotational driving force for the pulleys, which can provide driving force for the entire drill pipe transfer equipment to move forward or backward. There is no need for manual pushing of the main frame. By enabling the drill pipe transfer equipment to climb steps or cross obstacles and to perform planar movement on its own, the transfer efficiency of drill pipes can be greatly improved, which helps to prepare for oil exploration and saves labor costs required for exploration.

Detailed Implementation

[0036] To make the technical problems solved by the present invention, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected" and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0038] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0039] In oil exploration, non-powered flatbed trucks, manpower, and cranes are typically used to move and hoist drill pipes and other tools that need to be transported. This method of transport has the following problems:

[0040] (1) In terms of transfer efficiency: The existing transfer methods are time-consuming and inefficient. They require the cooperation of multiple equipment (e.g., cranes) and a large number of personnel. Furthermore, they are not adaptable to the working environment during the transfer process and cannot cross obstacles, resulting in even lower transfer efficiency.

[0041] (2) Regarding the protection of items: The damage rate of items during transportation is relatively high;

[0042] (3) Equipment manufacturing cost: The existing drill pipe transfer solution requires the use of multiple equipment, and the cost of the drill pipe transfer equipment is relatively high;

[0043] (4) In terms of safety: The existing transfer tools use electricity as their power source and work by dragging cables, which poses a great safety hazard on offshore platforms. At the same time, the coordination of multiple people and multiple machines during the transfer process is also one of the safety hazards.

[0044] Based on the above situation, in order to resolve the above problem, please refer to... Figures 1 to 17This invention provides a drill pipe transfer device, including a main frame 100 and traveling wheels 200. There are at least two sets of traveling wheels 200, arranged at intervals along the length of the main frame 100. Each set of traveling wheels 200 can be independently controlled. Each set of traveling wheels 200 includes at least one lifting mechanism 300. The lifting mechanism 300 includes a lifting bracket 310, a swing member 320, a pulley 330, a rolling drive member 340, and a telescopic drive member 350. The lifting bracket 310 is connected to the main frame 100. One end of the swing member 320 is rotatably connected to the lifting bracket 310. The pulley 330 is connected to the swing member... The other end of 320 is rotatably connected to the rolling drive 340, which includes a main body and an output part. The main body is connected to the swing member 320, and the output part is connected to the pulley 330. The rolling drive 340 can drive the pulley 330 to rotate relative to the swing member 320. The telescopic drive 350 includes a first part and a second part that can be telescopically connected. The first part is rotatably connected to the lifting bracket 310, and the second part is rotatably connected to the swing member 320. The telescopic drive 350 can drive the swing member 320 to rotate relative to the lifting bracket 310, so that the pulley 330 can reciprocate between positions close to and away from the main frame 100.

[0045] It should be noted that the main frame 100 is also equipped with a power supply and control system. The power supply can provide power to the traveling wheels 200, and the control system can issue command signals to control the traveling wheels 200 to perform corresponding actions. There can be two or more sets of traveling wheels 200, and at least one set of traveling wheels 200 includes two lifting mechanisms 300. The two lifting mechanisms 300 are located on both sides of the main frame 100, that is, there are at least three lifting mechanisms 300 at the bottom of the main frame 100. Three or more lifting mechanisms 300 can be used to form a three-wheeled transfer device, a four-wheeled transfer device, or a multi-wheeled transfer device to ensure that the entire drill pipe transfer device can be in a balanced state during operation. The rolling drive component 340 of the lifting mechanism 300 can be an electric motor or a hydraulic motor, which can generate driving force to drive the pulley 330 to rotate. Each traveling wheel 200 or each lifting mechanism 300 is controlled independently, which can realize the lifting and support of a single pulley 330. In this way, not only can the drill pipe of the offshore platform be transferred, but the transfer device can also climb steps and cross obstacles.

[0046] As one optional implementation, the telescopic drive 350 is a lifting cylinder, with a first component being the cylinder body and a second component being the piston rod. The cylinder body is rotatably connected to the lifting bracket 310, and the piston rod is rotatably connected to the swing member 320. The cylinder body can drive the swing member 320 to rotate relative to the lifting bracket 310 through the telescopic movement of the piston rod. As another optional implementation, the telescopic drive 350 is a lifting cylinder, with a first component being the piston rod and a second component being the cylinder body. The piston rod is rotatably connected to the lifting bracket 310, and the cylinder body is rotatably connected to the swing member 320. The cylinder body can drive the swing member 320 to rotate relative to the lifting bracket 310 through the telescopic movement of the piston rod.

[0047] Please see Figures 6-8 When encountering steps or obstacles, the lifting mechanism 300 of the front traveling wheel 200 can control the telescopic movement between the first and second components via the telescopic drive 350. This, in turn, drives the swing component 320 and the pulley 330 mounted on the swing component 320 to rotate relative to the lifting bracket 310. This ensures that the minimum height of the pulley 330 of the front traveling wheel 200 is higher than the minimum height of the pulley 330 of the rear traveling wheel 200, enabling each set of traveling wheels 200 to climb steps and cross obstacles. Consequently, the entire drill pipe transfer equipment can climb steps or cross obstacles without manual lifting or crane lifting. Furthermore, the rolling drive 340 provides rotational driving force to the pulley 330, which in turn provides driving force for the entire drill pipe transfer equipment to move forward or backward. This eliminates the need for manual pushing of the main frame 100. By enabling the drill pipe transfer equipment to climb steps or cross obstacles and to perform planar movement independently, the transfer efficiency of drill pipes can be greatly improved, which helps in the preliminary preparation for oil exploration and saves on the labor costs required for exploration.

[0048] Please see Figures 4-5 The swing member 320 includes two parallel swing plates 322 connected by a first rotating shaft 321. The two ends of the first rotating shaft 321 are rotatably connected to the two sides of the lifting bracket 310. A second component is connected to a second rotating shaft 351, the two ends of which are rotatably connected to the two swing plates 322. By having the two parallel swing plates 322 together form the swing member 320, it is not only convenient for the swing member 320 to be rotatably connected to the lifting bracket 310 via the first rotating shaft 321, but it also provides stable support for the pulley 330 located between the two swing plates 322, allowing the pulley 330 to roll stably under the drive of the rolling drive member 340. Simultaneously, the arrangement of the two swing plates 322 also facilitates the rotatable connection between the piston rod of the telescopic drive member 350 and the swing member 320 via the second rotating shaft 351.

[0049] It should be noted that the lifting bracket 310 includes a top plate and two side plates, which are respectively located on both sides of the top plate. The two ends of the first rotating shaft 321 are rotatably connected to the two side plates respectively. When the telescopic drive component 350 is a hydraulic cylinder, a collar is detachably fitted on the outer periphery of the hydraulic cylinder. The two sides of the collar are rotatably connected to the side plates through pins. The collar not only satisfies the rotatable connection between the hydraulic cylinder and the lifting bracket 310, but also allows for disassembly and replacement when the hydraulic cylinder needs to be replaced.

[0050] Please continue reading. Figures 4-5 The lifting bracket 310 is provided with a clearance hole 311 to allow space for the telescopic drive component 350 to move. When the lifting bracket 310 includes a top plate and two side plates, the clearance hole 311 is provided on the top plate. The clearance hole 311 allows space for the telescopic drive component 350 to move. In particular, when the lifting mechanism 300 needs to raise the height of the pulley 330 or reduce the distance between the pulley 330 and the main frame 100, the swing component 320 will drive the telescopic drive component 350 to move upward. The clearance hole 311 can effectively provide space for the telescopic drive component 350 to move. Moreover, the clearance hole 311 can make the entire lifting bracket 310 structure more compact, which is beneficial to improving space utilization.

[0051] It should be noted that in the lifting mechanism 300, the lifting action of the pulley 330 is achieved by the extension and retraction of the piston rod controlled by the telescopic drive component 350, which in turn drives the extension and retraction of the lifting bracket 310. Since the lifting bracket 310 is connected and fixed to the main frame 100, the lifting action of the main frame 100 is indirectly realized. During transportation, the main frame 100 is generally at its highest point and moves forward. At the same time, since the hydraulic cylinder of the lifting mechanism 300 is controlled independently, when the main frame 100 encounters an obstacle or step, the retraction action of a single set of lifting mechanisms 300 can be realized, thereby realizing the function of crossing the obstacle.

[0052] Please see Figures 1-3It also includes a shelf 400 and a flip drive 500. At least one end of the shelf 400 is detachably rotatably connected to the main frame 100. One end of the flip drive 500 is connected to the shelf 400 and the other end is connected to the main frame 100. The flip drive 500 can drive the shelf 400 to rotate relative to the main frame 100. The tilting drive 500 can drive the carrier 400 to rotate relative to the main frame 100. On the one hand, before the transfer operation, the tilting drive 500 can tilt the carrier 400 so that the workers can install the drill rod or other objects on the carrier 400. After installation, the tilting drive 500 can rotate the carrier 400 loaded with objects to above the main frame 100 for subsequent transfer operations. On the other hand, when the transfer equipment moves to the required position, the tilting drive 500 can tilt the carrier 400 so that the workers can remove the drill rod or other objects from the carrier 400, thereby realizing the transfer of the drill rod or other objects to the designated position.

[0053] It should be noted that both ends of the shelf 400 can be detachably and rotatably connected to the main frame 100. Please refer to [link / reference]. Figure 1 The right end of the shelf 400 is detached from the main frame 100, while the left end of the shelf 400 is rotatably connected to the main frame 100. Driven by the tilting drive 500, the shelf 400 can tilt upwards from left to right. Please refer to [link / reference]. Figure 2 The left end of the shelf 400 is detached from the main frame 100, and the right end of the shelf 400 is rotatably connected to the main frame 100. Driven by the flipping drive 500, the shelf 400 can tilt upward from right to left.

[0054] Please continue reading. Figures 1-3 The tilting drive unit 500 includes two telescopic mechanisms 510. The first end of each telescopic mechanism 510 is hinged to the shelf 400, and the second end is hinged to the main frame 100. The first ends of the two telescopic mechanisms 510 are spaced apart along the length of the shelf 400, and the second ends are also spaced apart along the length of the main frame 100. The two telescopic mechanisms 510 can control the shelf 400 to tilt left or right according to the actual situation of installing or removing drill rods or other objects, allowing the shelf 400 to tilt at a more suitable angle. This makes it easier for workers to install or remove drill rods or other objects from the shelf 400.

[0055] As an optional implementation, the two telescopic mechanisms 510 are arranged in an X-shape, meaning that the first ends of the two telescopic mechanisms 510 are spaced apart along a first direction, and the second ends of the two telescopic mechanisms 510 are spaced apart along a second direction. When the main frame 100 is parallel to the carrying rack 400, the first and second directions are opposite. By using two telescopic mechanisms 510 arranged in an X-shape, not only can the tilting requirements of the carrying rack 400 to the left or right be met according to the actual situation of installing or disassembling objects such as drill rods, but it can also improve the stability of the carrying rack 400, which helps to avoid the risk of the carrying rack 400 tipping over due to excessive shift of its center of gravity to one side during the flipping process.

[0056] It should be noted that each telescopic mechanism 510 can be a hydraulic cylinder. The hydraulic cylinder is rotatably mounted on the main frame 100 via a rotating seat. The piston rod of the hydraulic cylinder is rotatably connected to the carrying rack 400. The two telescopic mechanisms 510 are arranged in an X-shape, meaning that the rotating seat of one telescopic mechanism 510 (hereinafter referred to as the left telescopic mechanism 510) is further to the left than the rotating seat of the other telescopic mechanism 510, and the hinge point between the piston rod of this left telescopic mechanism 510 and the carrying rack 400 is further to the right than the hinge point between the piston rod of the other telescopic mechanism 510 and the carrying rack 400. Please refer to [link / reference needed]. Figure 1 When the shelf 400 needs to be tilted to the left, the piston rod of the left telescopic mechanism 510 extends, and the piston rod of the right telescopic mechanism 510 shortens, thus tilting the shelf 400 to the left; please refer to Figure 2 When the shelf 400 needs to be tilted to the right, the piston rod of the left telescopic mechanism 510 will shorten and the piston rod of the right telescopic mechanism 510 will extend, so as to tilt the shelf 400 to the right.

[0057] In one embodiment, please refer to Figures 9-10 A rotating engagement assembly 600 is provided between the main frame 100 and the shelf 400. The rotating engagement assembly 600 includes a mounting shaft 610 and a mounting base 620. The mounting base 620 is provided with a mounting groove 621 having an assembly opening. The mounting shaft 610 can be mounted in the mounting groove 621 through the assembly opening. The mounting shaft 610 is rotatably connected to the shelf 400, and the mounting base 620 is connected to the main frame 100. When the shelf 400 needs to be flipped, the mounting shaft 610 of the rotating engagement assembly 600 can serve as a rotation fulcrum between the shelf 400 and the main frame 100. Under the power drive of the flipping drive 500, the shelf 400 can rotate relative to the main frame 100 around the mounting shaft 610. By adding the rotating engagement assembly 600 as a rotation fulcrum between the shelf 400 and the main frame 100, the stability during the flipping process can be ensured, making it easier to control the shelf 400 to tilt to the required angle, improving work efficiency while ensuring operational safety.

[0058] It should be noted that you should refer to [link / reference]. Figures 9-10 The shelf 400 is rotatably connected to the mounting shaft 610 via the connecting seat 410. Please refer to [link / reference]. Figure 11 and Figure 12 The connecting seat 410 is rotatably connected to the mounting shaft 610 via the shaft assembly 420. This arrangement eliminates the need for the mounting shaft 610 to rotate during the flipping process, allowing the shelf 400 to rotate relative to the main frame 100. This avoids the situation where the mounting shaft 610 is prone to friction and wear during rotation and requires frequent replacement.

[0059] In another embodiment, a rotating engagement assembly 600 is provided between the main frame 100 and the shelf 400. The rotating engagement assembly 600 includes a mounting shaft 610 and a mounting base 620. The mounting base 620 is provided with a mounting groove 621 having an assembly opening. The mounting shaft 610 can be mounted in the mounting groove 621 through the assembly opening. The mounting shaft 610 is rotatably connected to the main frame 100, and the mounting base 620 is connected to the shelf 400. In this configuration, the mounting shaft 610 of the rotating engagement assembly 600 can also serve as a rotation fulcrum between the shelf 400 and the main frame 100. Under the power drive of the flipping drive 500, the shelf 400 can rotate relative to the main frame 100 around the mounting shaft 610.

[0060] Please see Figure 1 and Figure 2 The rotating engagement components 600 consist of two sets, located at opposite ends of the main frame 100. These components allow for detachable rotatable connection between the rack 400 and the main frame 100. The two sets of rotating engagement components 600 serve as pivot points for the rack 400 to rotate left and right relative to the main frame 100, ensuring good stability during these rotations. This improves work efficiency while maintaining operational safety. Furthermore, the rotating engagement components 600 also act as support points for the rack 400, ensuring it remains stably positioned at the required angle during installation or removal of items, facilitating easier installation and removal by operators.

[0061] Please see Figures 9-14The main frame 100 is provided with a first clutch 700, which includes a first clutch head 710, a guide seat 720, a first piston rod 730, and a first hydraulic cylinder 740. The guide seat 720 is connected to the main frame 100, and the first hydraulic cylinder 740 is connected to the guide seat 720. The first clutch head 710 is movably disposed on the guide seat 720. The first piston rod 730 connects the first hydraulic cylinder 740 and the first clutch head 710. The first clutch head 710 is provided with a first limiting groove 711 corresponding to the mounting shaft 610. The first hydraulic cylinder 740 can drive the first clutch head 710 to move in a direction close to the mounting shaft 610 through the first piston rod 730, so that the end of the mounting shaft 610 is located in the first limiting groove 711, thereby limiting the mounting shaft 610. When it is necessary to fix the mounting shaft 610, the first hydraulic cylinder 740 can control the first piston rod 730 to extend and retract, so that the first piston rod 730 pushes the first clutch head 710 to move under the guidance of the guide seat 720 until part of the mounting shaft 610 is located in the first limiting groove 711 of the first clutch head 710. The first clutch 700 can limit the mounting shaft 610 along the axial direction of the mounting shaft 610, which helps to prevent the mounting shaft 610 from being driven to move during the flipping of the shelf 400, and avoids the situation that is not conducive to the mounting shaft 610 being able to stably serve as the rotation fulcrum and support point of the shelf 400.

[0062] It should be noted that there can be two sets of first clutches 700, with the two sets of first clutches 700 respectively located at both ends of the mounting shaft 610. The two sets of first clutches 700 together limit the mounting shaft 610 along the axial direction of the mounting shaft 610. Alternatively, there can be one set of first clutches 700, with one end of the mounting shaft 610 directly abutting and limiting it through a component on the main frame 100, while the first clutch 700 is located at the other end of the mounting shaft 610. The first clutch 700 and the component on the main frame 100 together limit the mounting shaft 610 along the axial direction of the mounting shaft 610.

[0063] Please see Figure 9 , Figure 10 as well as Figures 15-17The mounting base 620 is provided with a second clutch 800, which includes a second clutch head 810, a fixed base 820, a second piston rod 830, and a second hydraulic cylinder 840. The second hydraulic cylinder 840 is connected to the mounting base 620. The mounting base 620 is provided with a guide groove 622. The second clutch head 810 is movably disposed in the guide groove 622. The second piston rod 830 connects the second hydraulic cylinder 840 and the second clutch head 810. The second clutch head 810 is provided with a second limiting groove 811. The second hydraulic cylinder 840 can drive the second clutch head 810 to move in a direction close to the mounting shaft 610 through the second piston rod 830, so that the groove wall of the second limiting groove 811 abuts against the mounting shaft 610 to form a limiting effect on the mounting shaft 610. When it is necessary to fix the mounting shaft 610, the second hydraulic cylinder 840 can control the second piston rod 830 to extend and retract, so that the second piston rod 830 pushes the second clutch head 810 to move under the guidance of the guide groove 622 of the mounting seat 620 until the second clutch head 810 contacts and abuts against the outer peripheral wall of the mounting shaft 610 through the second limiting groove 811. The setting of the second clutch 800 can limit the mounting shaft 610 in the radial direction, which helps to prevent the mounting shaft 610 from being driven to rotate during the flipping of the shelf 400, and avoids the situation that is not conducive to the mounting shaft 610 being able to stably serve as the rotation fulcrum and support point of the shelf 400. Combined with the setting of the first clutch 700, the axial and radial directions of the mounting shaft 610 can be fixed and limited, ensuring that the mounting shaft 610 can stably serve as the rotation fulcrum and support point of the shelf 400, so that the workers can perform object disassembly or installation operations.

[0064] It should be noted that the second clutch 800 also includes a fixed seat 820. The second oil cylinder 840 is fixed to the mounting seat 620 through the fixed seat 820. There can be two sets of second clutches 800. The two sets of second clutches 800 are arranged along the length direction of the mounting shaft 610. The two sets of second clutches 800 can jointly limit the mounting shaft 610 along the radial direction of the mounting shaft 610.

[0065] Please see Figures 1 to 17 This embodiment provides a drill pipe transfer device, the working principle of which is as follows: During operation, the transfer device first extends the entire lifting mechanism 300 through the telescopic movement of the telescopic drive component 350. Once the device reaches its maximum height, drill pipes or other objects are loaded. Figure 6 As shown; under the driving action of the rolling drive component 340, the transfer equipment moves to the drilling platform step position via the pulley 330. The telescopic drive component 350 in front of the transfer equipment performs a return motion, causing the entire lifting mechanism 300 to retract. Then, the rolling drive component 340 drives the pulley 330 to move upward to cross the step, as shown. Figure 7As shown; after the front lifting mechanism 300 has completely crossed the step or obstacle, the telescopic drive component 350 drives the lifting mechanism 300 to extend, so that the pulley 330 contacts the guide rail 900 to support the transfer equipment again. Then the rear lifting mechanism 300 repeats the previous action of the front lifting mechanism 300 until the traveling wheels 200 have completely crossed the step or obstacle, as shown. Figure 8 As shown; when the transfer equipment reaches the designated position, it begins to flip. The transfer equipment can flip left and right, as shown. Figure 1 As shown, when the transfer equipment flips to the left, the mounting shaft 610 located on the left side of the carrier 400 is fitted into the mounting groove 621 of the mounting seat 620 located on the left side of the main frame 100. The first clutch 700 and the second clutch 800 located on the left side of the main frame 100 close to limit and fix the mounting shaft 610. The first clutch 700 and the second clutch 800 located on the right side of the main frame 100 open to no longer restrict the mounting shaft 610. Then, the telescopic mechanism 510 of the flipping drive 500 correspondingly telescopically moves to flip the carrier 400 to the left, thereby achieving the leftward flipping of the carrier 400 to the required angle for installing or removing drill rods or other objects; as Figure 2 As shown, when the transfer equipment flips to the right, the mounting shaft 610 located on the right side of the carrier 400 is fitted into the mounting groove 621 of the mounting seat 620 located on the right side of the main frame 100. The first clutch 700 and the second clutch 800 located on the right side of the main frame 100 close to limit and fix the mounting shaft 610. The first clutch 700 and the second clutch 800 located on the left side of the main frame 100 open to no longer restrict the mounting shaft 610. Then, the telescopic mechanism 510 of the flipping drive 500 telescopically extends and retracts accordingly to flip the carrier 400 to the right, thereby flipping the carrier 400 to the right to the required angle for installing or removing drill rods or other objects.

[0066] It should be noted that the lifting mechanism 300, the tilting drive component 500, the first clutch 700, and the second clutch 800 are all controlled by a control unit located on the main frame 100. By adding an electrical system control unit, the transfer equipment becomes more intelligent, achieving continuous, smooth, and stable operation, which helps improve the transfer efficiency between the offshore platform and the exploration vessel. Furthermore, by installing the first clutch 700 and the second clutch 800 on both sides of the main frame 100, the left and right tilting function of the load rack 400 can be achieved by controlling the operation of these clutches. This not only eliminates the cumbersome work of a crane but also simplifies the coordination of multiple personnel and machinery, while improving work efficiency and operational safety. It also reduces the types and number of equipment on the offshore platform, thus saving exploration costs. Compared to unpowered flatbed trucks, this invention has advantages such as simple structure, high level of intelligence, strong functionality, low cost, high safety, convenient use and maintenance, high efficiency, and wide applicability. Moreover, the transfer efficiency is at least half higher than that of unpowered flatbed trucks.

[0067] This invention also provides a vessel, including a hull and the aforementioned drill pipe transfer equipment. The hull is equipped with a guide rail 900, and the drill pipe transfer equipment is slidably mounted on the guide rail 900 via pulleys 330. Due to the special structure of ships, manually handling drill pipe equipment is more inconvenient on ships. By setting the guide rail 900 on the hull corresponding to the pulleys 330 of the drill pipe transfer equipment, the drill pipe transfer equipment can be easily moved on the hull, facilitating the rapid transport of drill pipes and other objects to the required location on the hull. In particular, when ships are conducting offshore exploration, the drilling location needs to change according to changes in survey results. The guide rail 900 and the drill pipe transfer equipment can well adapt to the transportation needs of changing drilling locations, thereby solving the inconvenience of offshore exploration and other operations. Furthermore, compared to some existing transfer equipment with obstacle-crossing capabilities (such as tracked transfer equipment), the guide rail 900 of this invention not only utilizes the limiting effect of the guide rail 900 on the pulley 330 to ensure the stability of the drill pipe transfer equipment during the transfer process, but also serves to remind the personnel on board that this is the operating channel of the drill pipe transfer equipment. This helps to prevent the personnel on board from lingering in the operating channel of the drill pipe transfer equipment and interfering with the normal transfer operation. At the same time, the guide rail 900 also limits the operation of the drill pipe transfer equipment to a designated area, which helps to avoid the risk of the drill pipe transfer equipment colliding with the personnel on board.

[0068] Please see Figure 1 and Figure 2Each set of traveling wheels 200 includes two lifting mechanisms 300, which are respectively located on both sides of the main frame 100. All pulleys 330 located on the same side of the main frame 100 are arranged on the same straight line. This allows for the installation of guide rails 900 on the pulleys 330 located on the same side of the main frame 100, enabling the pulleys 330 to slide along the guide rails 900 during transport. This not only provides excellent guidance, ensuring smooth and unobstructed transport operations in the area where the guide rails 900 are installed, thus improving transport efficiency, but also helps the drill pipe transport equipment maintain a balanced state during operation, ensuring stability when transporting drill pipes or other objects, thereby significantly reducing the damage rate of drill pipes or other objects during transportation.
