Abstract
Description
Technical Field
[0001] This utility model belongs to the field of petroleum equipment manufacturing technology, specifically relating to a petroleum equipment transfer device. Background Technology
[0002] The base is a crucial component of the drilling rig, primarily supporting the derrick and facilitating the installation and operation of wellhead equipment. Its structural performance directly impacts the overall stability and operational efficiency of the drilling rig. Currently, the relocation of traditional drilling rig bases mainly employs two methods: one suitable for cluster drilling rigs, using sliding or short-distance hoisting for short-distance relocation within the well site, typically involving short distances and high operational frequency; the other used for long-distance relocation between oil fields, requiring heavy-duty transport vehicles or modular trailers, resulting in a complex process and stringent requirements for road and transportation conditions.
[0003] However, existing technologies often fall short when drilling rigs need to simultaneously meet the requirements of long-distance relocation and rapid inter-well transport. Because the two transport modes differ significantly in equipment requirements, operating procedures, and technical standards, two independent transport systems are typically required. This not only increases equipment investment and space requirements but also leads to difficulties in coordination and repeated disassembly and assembly during actual operation. Furthermore, the maintenance costs of multiple systems are high, and on-site commissioning and preparation are time-consuming and labor-intensive, severely impacting the continuity and economy of drilling operations and hindering the demand for efficient exploration and development. Utility Model Content
[0004] To address the aforementioned problems in the existing technology, this utility model provides a transfer device for oilfield equipment. The technical problem to be solved by this utility model is achieved through the following technical solution:
[0005] This utility model provides a transport device for oilfield equipment, comprising: a towing seat assembly, a front gooseneck assembly, a cantilever support, a telescopic rod, and tires, wherein...
[0006] The first end of the towing seat assembly is hinged to the rear of the trailer, and the second end is hinged to the first end of the front gooseneck assembly; the second end of the front gooseneck assembly is multi-directionally hinged to the front end of the drilling rig base.
[0007] The cantilever support is hinged to the rear end of the drilling rig base; the telescopic rod is hinged to the cantilever support; and the tire is fixedly connected to the end of the telescopic rod.
[0008] In one embodiment of the present invention, a towing pin is fixedly connected to the bottom of the first end of the towing seat assembly, and the towing pin is inserted into and hinged to the towing seat at the rear of the trailer.
[0009] In one embodiment of the present invention, the first end of the front gooseneck assembly is provided with an ear seat, and the front gooseneck assembly is hinged to the second end of the traction seat assembly through the ear seat and a pin inserted into the ear seat.
[0010] In one embodiment of the present invention, the second end of the front gooseneck assembly is hinged to the front end of the drill base via lugs in two directions.
[0011] In one embodiment of this utility model, the cantilever support is hinged to the bottom rear end of the drilling rig base via two lugs fixed at its lower end.
[0012] In one embodiment of this utility model, a plurality of pin holes are provided near the top of the telescopic rod. The plurality of pin holes are distributed at intervals along the radial direction of the telescopic rod.

[0013] In one embodiment of the present invention, the oil equipment transfer device further includes an auxiliary cylinder, the end of the cylinder barrel of the auxiliary cylinder being hinged to the cantilever support; the end of the piston rod of the auxiliary cylinder being hinged to the telescopic rod.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0015] This utility model discloses a transport device for oilfield equipment. By using multiple lugs in different directions to fix each component and restrict its degree of freedom, it prevents tilting even under the heavy pressure of the drilling rig base. Furthermore, by selecting different lug connections, foldable components can be achieved to save space. No external force is needed when lifting the drilling rig base, saving manpower and resources.

[0021] The foregoing and other technical contents, features, and effects of this utility model will be clearly presented in the following detailed description of the specific embodiments with reference to the accompanying drawings. Through the description of the specific embodiments, a more in-depth and specific understanding can be gained of the technical means and effects adopted by this utility model to achieve the intended purpose. However, the accompanying drawings are only provided for reference and illustration and are not intended to limit the technical solution of this utility model.
[0022] This utility model embodiment provides a device for transferring oilfield equipment. Please refer to [link to relevant documentation]. Figure 1 , Figure 1 This is a schematic diagram of the transportation status of a petroleum equipment transfer device provided in an embodiment of this utility model, as shown below. Figure 1 As shown, the oil equipment transfer device of this embodiment includes: a towing seat assembly 2, a front gooseneck assembly 3, a cantilever support 5, a telescopic rod 6, and a tire 7.
[0023] The first end of the towing seat assembly 2 is hinged to the rear of the trailer 1, and the second end is hinged to the first end of the front gooseneck assembly 3; the second end of the front gooseneck assembly 3 is multi-directionally hinged to the front end of the drill base 4; the cantilever support 5 is hinged to the rear end of the drill base 4; the telescopic rod 6 is hinged to the cantilever support 5; and the tire 7 is fixedly connected to the end of the telescopic rod 6.
[0024] In an optional embodiment, a towing pin is fixed to the bottom of the first end of the towing seat assembly 2, and the towing pin is inserted into and hinged to the towing seat at the rear of the trailer 1.
[0025] Optionally, the towing pin can be a universal towing pin, and the towing seat can be a universal towing seat. The articulation point between the towing seat assembly 2 and the trailer constitutes the main traction force transmission point of the entire transfer device, allowing a certain degree of pitch and sway during travel.
[0026] In an optional embodiment, the first end of the front gooseneck assembly 3 is provided with an ear seat, and the front gooseneck assembly 3 is hinged to the second end of the traction seat assembly 2 via the ear seat and a pin inserted into the ear seat.
[0027] In this embodiment, the hinge point between the front gooseneck assembly 3 and the traction seat assembly 2 allows the traction seat assembly 2 to be folded relative to the front gooseneck assembly 3 when not in use, in order to save space.
[0028] In an optional embodiment, the second end of the front gooseneck assembly 3 is hinged to the front end of the drill base 4 via lugs in two directions.
[0029] In this embodiment, the two-direction lugs refer to the two hinged lugs with different pin axis directions. One set of lugs has a pin axis that is horizontal and perpendicular to the forward direction of the trailer 1 (i.e., laterally arranged). When the trailer 1 travels on rough roads, the front of the trailer and the base tend to move vertically. This hinge direction allows the front gooseneck assembly 3, along with the drill base 4, to swing up and down around the pin axis, thus preventing rigid interference and damage to the structure due to road undulations. This is crucial for ensuring smooth transportation. The other set of lugs can have a pin axis that is either vertical or horizontal and parallel to the forward direction of the vehicle (i.e., longitudinally arranged). If it is a vertical pin axis, then a small horizontal relative rotation (similar to a steering knuckle) is allowed between the front gooseneck assembly 3 and the drill base 4 to accommodate deviations caused by vehicle turning or lateral forces. If it is a longitudinal horizontal pin axis, then a small torsion in the lateral direction is allowed between the structures to counteract the lateral torque caused by uneven road surfaces. The hinge in this direction is mainly used to release harmful torsional stress, improve the fault tolerance of the entire connection device to complex working conditions, and ensure that the connection point will not be damaged due to stress concentration.
[0030] In this embodiment, the dual-direction lug connection allows the structure to generate the necessary relative movement during traction pitch, turning, and uneven road surfaces; simultaneously, it firmly restricts unintended movements in other directions (such as direct disengagement, lateral translation, etc.), ensuring the stability and reliability of the connection; moreover, it allows traction force, support force, and various impact forces to be smoothly transmitted and dissipated, rather than becoming destructive stress. This design fixes the relative position between the front gooseneck assembly 3 and the drill base 4, restricts unnecessary degrees of freedom, ensures connection rigidity, and adapts to stress and deformation in multiple directions.
[0031] Understandably, the cantilever support 5, telescopic rod 6, and tires 7 form a self-lifting rear axle assembly that integrates three major functions: travel, lifting, and support. By adjusting the height of this self-lifting rear axle assembly, the raising and lowering of the drilling rig base 4 can be controlled, thus enabling a single transport device to simultaneously meet the requirements of long-distance towing and well site positioning.
[0032] In an optional embodiment, the cantilever support 5 is hinged to the bottom rear end of the drill base 4 via two lugs fixed at its lower end.
[0033] In this embodiment, the hinge point between the cantilever support 5 and the drilling rig base 4 serves as the load-bearing fulcrum of the self-lifting rear axle assembly.
[0034] In an optional embodiment, the telescopic rod 6 is provided with a plurality of pin holes near its top end. The plurality of pin holes are distributed at intervals along the radial direction of the telescopic rod 6. By adjusting the pins, different pin holes can be selected to fix the telescopic rod 6 at different heights, thereby adjusting the height of the entire self-lifting rear axle assembly.
[0035] In an optional embodiment, the oilfield equipment transfer device further includes an auxiliary hydraulic cylinder ( Figure 1 (Not shown in the image) Optionally, the auxiliary cylinder can be integrated into the self-lifting rear axle assembly or used as a separate external tool.
[0036] When the auxiliary hydraulic cylinder is used as an independent external tool, the usage process of the oil equipment transfer device in this embodiment is as follows.
[0037] Transitioning from working to transport mode: The auxiliary support cylinder lifts the rear of the drilling rig base 4, partially unloading its weight. The operator adjusts the telescopic rod 6, selecting the lower pin hole position, allowing the tires 7 to lower and contact the ground, fully bearing the weight of the rear of the base, and then retracts the auxiliary support cylinder. The front gooseneck assembly 3 is connected to the lowered and locked towing seat assembly 2 using a pin. Simultaneously, the universal towing pin of the towing seat assembly 2 is connected to the universal towing seat at the rear of the trailer 1. The entire device is then moved by the trailer 1. Traction force is transmitted through the towing seat assembly 2, the front gooseneck assembly 3, and to the drilling rig base 4. Throughout the transport process, the multi-directional lug hinge design ensures structural stability, preventing tilting or deformation under heavy pressure and bumps.
[0038] Transitioning from transport to working status: After the transport unit arrives at the new well site, the auxiliary support cylinder lifts the rear of the drilling rig base 4, partially unloading its weight. The operator adjusts the telescopic rod 6, selects a higher pin hole position, and raises the tire 7 upwards. The auxiliary support cylinder slowly retracts, forcing the rear of the drilling rig base 4 to gradually descend until it is securely seated on the ground. The connection between the trailer 1 and the towing assembly 2 is disconnected, and the trailer 1 drives away. The towing assembly 2 is folded up from its connection point with the front gooseneck assembly 3 and secured in this storage position with a pin, minimizing the space occupied by the unit during well site operations and avoiding interference with drilling operations. A schematic diagram of the working status of the oilfield equipment transport unit is shown below. Figure 2 As shown, in the working state, the drilling rig base 4 sits directly on the ground and is in a stable state, allowing for derrick installation and drilling operations.
[0039] When the auxiliary cylinder is integrated into the self-lifting rear axle assembly, optionally, the cylinder end of the auxiliary cylinder is hinged to the cantilever support 5; the piston rod end of the auxiliary cylinder is hinged to the telescopic rod 6.
[0040] Understandably, the telescopic rod 6 and the cantilever support 5 are connected not only by the adjustable pin but also by a main pin. The main pin always connects the cantilever support 5 and the telescopic rod 6, allowing them to rotate relative to each other. That is, the extension and retraction of the auxiliary cylinder drives the telescopic rod 6 to rotate around the main pin hole connecting it to the cantilever support 5. The adjustable pin is inserted into a specific pin hole to lock the two together. This connection is rigid and static, designed to permanently bear the enormous weight and impact loads of the drilling rig base 4 during transport and operation.
[0041] When the auxiliary hydraulic cylinder is integrated into the self-lifting rear axle assembly, the usage process of the oil equipment transfer device in this embodiment is as follows.
[0042] Transitioning from working to transport mode: The base rests on the ground, the telescopic rod 6 is fixed to a high hole via the main pin, the tire 7 is off the ground, and the auxiliary support cylinder is retracted. The hydraulic system is activated, and the auxiliary support cylinder begins to extend. Since the two ends of the auxiliary support cylinder are hinged to the cantilever support 5 (fixed side) and the telescopic rod 6 (movable side) respectively, its extension generates a strong thrust, pushing the telescopic rod 6 to rotate downwards around the main pin. The telescopic rod 6 moves downwards, causing the tire 7 at its end to contact the ground. The auxiliary support cylinder continues to exert force, increasing the pressure of the tire 7 on the ground, and its reaction force eventually lifts the rear of the drilling rig base 4 entirely off the ground. Once the drilling rig base 4 is lifted to a sufficient height (at which point the target pin hole on the telescopic rod 6 aligns with the hole on the cantilever support), the operator inserts a high-strength adjustable pin. After the pin is inserted, the weight of the drilling rig base 4 is entirely borne by this rigid mechanical path of the cantilever support 5, the adjustable pin, the telescopic rod 6, the tire 7, and the ground. The hydraulic pressure in the auxiliary support cylinder is released, allowing it to retract completely or remain in a slightly unstressed state. At this point, the device enters the transport phase.
[0043] Transitioning from transport to operating mode: The auxiliary support cylinder extends slightly, pressing against the telescopic rod 6 to bear a small amount of weight, thus relieving the previously locked pin of stress. The operator can easily pull out the locking pin. The auxiliary support cylinder is then slowly retracted. The pulling force (or supporting force) of the auxiliary support cylinder controls the telescopic rod 6 to slowly retract upwards, causing the drill base 4 to descend smoothly and slowly. Once the drill base 4 is fully seated on the ground, the telescopic rod 6 is adjusted to its highest pin hole and the pin is inserted to lock it, lifting the tire 7 off the ground. The auxiliary support cylinder then fully retracts.
[0044] This utility model discloses a transportation device for oilfield equipment. By using multiple lugs in different directions to fix each component and restrict its degree of freedom, it prevents tilting even under the heavy pressure of the drilling rig base. Furthermore, by selecting different lug connections, foldable components can be achieved to save space. No external force is needed when lifting the drilling rig base, saving manpower and resources. For grounding, only the rear tires need to be lifted to bring the base to the ground, greatly saving time and making the entire transportation process faster and more efficient.
