Description

Technical Field

[0001] This utility model relates to the technical field of derrick assembly auxiliary devices, and in particular to a hydraulic support device for intelligent derrick assembly and disassembly in oil drilling. Background Technology

[0002] In the exploration and development of resources such as oil and natural gas, derricks are a critical piece of surface equipment, and the precision, efficiency, and safety of their installation and assembly are of paramount importance. Traditional derrick assembly operations generally rely on temporary support platforms, combined with external lifting equipment for hoisting and positioning.

[0003] This traditional work method has many inherent flaws: Poor flexibility and low efficiency: When connecting the various parts or the entire derrick, precise horizontal and vertical alignment is required. If there is any deviation in the initial position, large lifting equipment must be called in for fine-tuning. This process is not only cumbersome, time-consuming, and labor-intensive, but also heavily reliant on the availability of lifting equipment and the skill of the operators, resulting in low overall assembly efficiency.

[0004] Safety concerns exist: Under heavy loads, if the position is maintained primarily by the suspension of the crane hook, there is a risk of accidental falls due to equipment failure or operational errors. Furthermore, the stability and reliability of traditional temporary support structures cannot be fully guaranteed when subjected to enormous loads.

[0005] Poor fit with the derrick: The rigid support platform cannot adequately support the slightly tilted derrick, and the derrick itself has welding points and is not a flat structure, which makes it easy to damage the derrick when supporting it. Utility Model Content

[0006] (a) Technical problems to be solved In view of the above-mentioned shortcomings and deficiencies of the prior art, this utility model provides a hydraulic support device for intelligent disassembly and assembly of oil drilling derricks, which solves the technical problems of poor flexibility, low efficiency, poor safety and poor fit with the derrick in the existing operation methods.

[0007] (II) Technical Solution To achieve the above objectives, the main technical solutions adopted by this utility model include: Firstly, this utility model provides an intelligent hydraulic support device for assembling and disassembling derricks in oil drilling, suitable for supporting the derrick during assembly. It includes a frame, a lifting frame, and a traveling device. Several support legs are formed at the bottom of the frame. The lifting frame is vertically and vertically fixedly connected to the frame, and its top is adapted to support the derrick. The traveling device is vertically and vertically fixedly connected to the frame and can switch between a traveling state where it descends to independently support the frame and a stopped state where it rises above the support legs and independently supports the frame. In the traveling state, the traveling device can drive the lifting frame to move laterally, thereby matching the position of the lifting frame to the required position of the derrick. In the stopped state, the lifting frame can support the derrick. It also includes a contact frame located on the top of the lifting frame, suitable for adaptively fitting the derrick.

[0008] In one technical solution of this utility model, the contact frame includes a first swing head and a second swing head extending along a first horizontal direction; the first horizontal direction is perpendicular to the second horizontal direction; both the first swing head and the second swing head are V-shaped, and the middle part of the second swing head is hinged to both ends of the first swing head along the second horizontal direction; the two ends of the second swing head form a support part for supporting the derrick.

[0009] In one technical solution of this utility model, a slide table is also included. The contact frame is slidably connected to the lifting frame along the second horizontal direction via the slide table, and the slide table can drive the contact frame to move laterally with a limit along the second horizontal direction. The contact frame is hinged to the slide table along the second horizontal direction.

[0010] In one technical solution of this utility model, a sensing unit is also included, which is suitable for detecting the position to be supported of the derrick, thereby enabling the slide table to drive the supporting part of the contact frame to actively correspond with the position to be supported.

[0011] In one technical solution of this utility model, the walking device includes a first moving member, which is located on both sides of the frame and can drive the frame to move laterally in a first horizontal direction.

[0012] In one technical solution of this utility model, the walking device further includes a second moving part, which is located on both sides of the frame and can drive the frame to move laterally in the second horizontal direction.

[0013] In one technical solution of this utility model, it further includes multiple sets of first telescopic drive members and second telescopic drive members that extend vertically; the two ends of the first telescopic drive member are respectively fixedly connected to the walking device and the frame, and the two ends of the second telescopic drive member are respectively fixedly connected to the lifting frame and the frame.

[0014] In one technical solution of this utility model, multiple sets of sliding sleeve assemblies are also included. The two ends of the sliding sleeve assembly are respectively fixedly connected to the lifting frame and the machine frame to serve as guide components when the lifting frame is raised or lowered.

[0015] In one technical solution of this utility model, a locking component is also included. The locking component is fixedly connected to the frame and is suitable for selectively locking the sliding sleeve assembly. The locking component includes a third telescopic drive member and a locking pin.

A locking hole is provided on the sliding sleeve assembly, and the locking pin can selectively engage with the locking hole under the drive of the third telescopic drive member to limit the lifting of the lifting frame.

[0016] In one technical solution of this utility model, a load detection unit is also included, which is fixedly connected to the support part and is suitable for detecting the load of the support part.

[0017] (III) Beneficial Effects The beneficial effects of this utility model are as follows: The intelligent hydraulic support device for assembling and disassembling derricks in oil drilling integrates the walking function and the lifting support function into one unit, and introduces a walking device design that can be switched between lifting and lowering. This effectively solves the problem of frequent adjustment of the support position by relying on external hoisting equipment during the traditional derrick assembly process. On the one hand, the system can autonomously complete the fine-tuning of the position, greatly improving assembly efficiency and reducing manual intervention and investment in auxiliary equipment; on the other hand, when the system is stationary, the rigid support legs bear the load, avoiding the risk of deformation or slippage of flexible or rolling parts such as walking wheels under heavy load conditions, significantly improving operational safety and structural reliability.

[0018] Furthermore, the contact frame, which can adaptively conform to the derrick, not only enhances the compatibility of the lifting frame system with different types or states of derricks, but also significantly improves the safety and operational fault tolerance during the assembly process, thereby increasing overall operational efficiency.

[0021] To better explain and facilitate understanding of this utility model, the following description is provided in conjunction with the appendix. Figures 1-5 This invention will be described in detail through specific embodiments. Wherein, directional terms such as "upper" and "lower" are used in this document. Figure 1 The orientation is used as a reference.

[0022] Example 1: Reference Figures 1-5 This utility model provides an intelligent hydraulic support device for assembling and disassembling derricks in oil drilling, suitable for supporting the derrick during assembly. It includes a frame 1, a lifting frame 2, and a traveling device 3. The frame 1 has several support legs at its bottom. The lifting frame 2 is vertically and vertically fixedly connected to the frame 1, and its top is adapted to support the derrick. The traveling device 3 is vertically and vertically fixedly connected to the frame 1 and can switch between a traveling state where it descends to independently support the frame 1 and a stopped state where it rises above the support legs and independently supports the frame 1. In the traveling state, the traveling device 3 can drive the lifting frame 2 to move laterally, thereby matching the position of the lifting frame 2 to the required position of the derrick. In the stopped state, the lifting frame 2 can support the derrick. It also includes a contact frame 4 located on the top of the lifting frame, suitable for adaptively fitting the derrick.

[0023] In this embodiment, the intelligent hydraulic support device for derrick assembly and disassembly in oil drilling is specifically designed for derrick assembly operations. The overall structure comprises three main parts: a frame 1, a lifting frame 2, and a traveling device 3. These components work together to achieve efficient, precise, and safe derrick support and positioning. The frame 1 serves as the system's basic load-bearing structure, with several support feet at its bottom to provide stable and reliable static support during operation. The lifting frame 2 is vertically and liftably connected to the frame 1, and its top has a support surface adapted to the derrick's bottom structure. This allows for reliable lifting of the derrick during assembly and flexible height adjustment according to the required derrick installation height.

[0024] The walking device 3 is integrated into the bottom of the frame 1 and has a height-adjustable structure, which can flexibly switch between two working states: When in walking state, the walking device 3 lowers to a position below the support feet, independently bears the weight of the entire system, and drives the frame 1 and the lifting frame 2 to move laterally as a whole through its own drive mechanism, thereby precisely adjusting the position of the lifting frame 2 on the horizontal plane so that it is precisely aligned with the required installation position of the derrick; after the position adjustment is completed, the walking device 3 rises to a position above the support feet, so that the support feet re-contact the ground and bear the full load of the system. At this time, the system enters a stopped state, and the walking device 3 no longer participates in load bearing, thereby ensuring the stability and safety of the entire support structure during the derrick assembly process.

[0025] This technical solution integrates the walking and lifting support functions into one unit and introduces a walking device 3 that can be raised and lowered, effectively solving the problem of frequent adjustments to the support position requiring external hoisting equipment during traditional derrick assembly. On the one hand, the system can autonomously perform fine-tuning of the position, significantly improving assembly efficiency and reducing manual intervention and auxiliary equipment investment; on the other hand, when stationary, the rigid support legs bear the load, avoiding the risk of deformation or slippage of flexible or rolling components such as walking wheels under heavy load conditions, significantly improving operational safety and structural reliability. Furthermore, the contact frame 4, which can adaptively conform to the derrick, not only enhances the compatibility of the lifting frame 2 system with different types or states of derricks, but also significantly improves safety and operational fault tolerance during assembly, increasing overall operational efficiency.

[0026] Specifically, the top two sides of the frame 1 are equipped with suspended baskets, allowing workers to assemble the derrick within the baskets. The frame 1 is also equipped with ladders for workers to climb onto the suspended baskets.

[0027] Example 2: Reference Figures 1-5 In addition to possessing all the technical solutions of the above embodiments, the embodiments of this utility model further possess the following technical solutions: The contact frame 4 includes a first swing head 41 and a second swing head 42 extending along a first horizontal direction X; both the first swing head 41 and the second swing head 42 are V-shaped, and the middle part of the second swing head 42 is hinged to both ends of the first swing head 41 along a second horizontal direction Y; the two ends of the second swing head 42 form support parts for supporting the derrick. When the system is in use, the derrick extends along the vertical plane of the first horizontal direction X, which is perpendicular to the second horizontal direction Y.

[0028] The support part can be configured as a support plate 43, which is hinged to both ends of the second swing head 42 along the second horizontal direction Y, thereby forming two support surfaces at both ends of each second swing head 42. Since a contact frame 4 has two sets of second swing heads 42, it will have four sets of support surfaces. Furthermore, each support surface can adaptively fit the surface of the derrick, thereby improving the support stability of the derrick.

[0029] In this embodiment, the middle part of the first swing head 41 is hinged to the top of the lifting frame 2 along the second horizontal direction Y, so that the entire contact frame 4 can have a certain degree of swing freedom in this direction; the middle part of the second swing head 42 is also hinged to both ends of the first swing head 41 along the second horizontal direction Y, thereby forming a swingable double-arm structure. The two ends of the second swing head 42 are respectively provided with support parts for directly contacting and supporting the derrick.

[0030] Furthermore, the support portion can be specifically implemented as a support plate 43, which is hinged to both ends of the second swing head 42 along the second horizontal direction Y, so that each end of the second swing head 42 can form two independent support surfaces. Since one contact frame 4 is equipped with two second swing heads 42, the whole can provide four sets of support surfaces. These support surfaces are not only symmetrically distributed in space, but each also has a degree of freedom to rotate around the hinge axis, and can automatically adjust the angle according to the local changes in the bottom profile of the derrick to achieve adaptive contact with the derrick surface. This multi-point, multi-degree-of-freedom flexible contact mechanism effectively disperses the derrick load and avoids the risk of structural damage or slippage caused by local stress concentration.

[0031] In actual use, the derrick extends along the vertical plane of the first horizontal direction X, which is perpendicular to the second horizontal direction Y. The structural design of the contact frame 4 is precisely matched with this arrangement: the second swing head 42 swings in the plane of the first horizontal direction X, conforming to the geometry of the derrick; the hinge of the support plate 43 in the second horizontal direction Y allows for fine-tuning of its posture in the width direction of the derrick. This swing of the first swing head 41 relative to the lifting frame 2, the swing of the second swing head 42 relative to the first swing head 41, and the swing of the support relative to the second swing head 42 constitutes multiple adaptive adjustment capabilities. This ensures that regardless of slight manufacturing deviations, installation tilts, or surface unevenness of the derrick, the contact frame 4 can achieve stable and uniform support through the independent adjustment of each support surface.

[0032] In summary, this improvement not only enhances the compatibility of the lifting frame 2 system with different types or states of derricks, but also significantly improves safety and operational fault tolerance during assembly. Simultaneously, the ability to achieve high-fit support without additional manual intervention reduces adjustment time and labor costs, improving overall operational efficiency. Furthermore, the multi-support surface distribution structure provides better anti-overturning capability and dynamic stability when the derrick is subjected to dynamic loads such as wind loads or vibrations, further ensuring on-site construction safety.

[0033] Example 3: Reference Figures 1-5 In addition to possessing all the technical solutions of the above embodiments, the embodiments of this utility model further possess the following technical solutions: The intelligent hydraulic support device for disassembling and assembling derricks in oil drilling also includes a slide table 5. The contact frame 4 is slidably connected to the lifting frame 2 along the second horizontal direction Y via the slide table 5, and the slide table 5 can drive the contact frame 4 to move laterally with a limit along the second horizontal direction Y. The contact frame 4 is hinged to the slide table 5 along the second horizontal direction Y.

[0034] In this embodiment, based on the aforementioned intelligent hydraulic support device for derrick assembly and disassembly in oil drilling, a slide table 5 structure is further introduced, enabling the contact frame 4 to not only possess multi-degree-of-freedom adaptive support capabilities but also controllable lateral adjustment functionality. Specifically, the contact frame 4 is not directly fixed to the top of the lifting frame 2, but is slidably connected to the lifting frame 2 along the second horizontal direction Y via the slide table 5. The slide table 5 itself integrates a drive mechanism, which can drive the entire contact frame 4 to perform limited lateral movement in the second horizontal direction Y.

[0035] First, the controllable lateral movement capability provided by the slide table 5 allows the contact frame 4 to actively adjust its position in the second horizontal direction Y even when the derrick is not fully in place or there is lateral offset, achieving rapid alignment with the bottom support point of the derrick and avoiding forced assembly or additional hoisting adjustments due to initial positioning deviations. Second, since the contact frame 4 is still installed on the slide table 5 via a hinge, the original adaptive swing capability of its first swing head 41 and second swing head 42 system remains unaffected. Even after the slide table 5 completes lateral positioning, each supporting surface can still independently adjust its posture according to the local contour of the derrick, ensuring multi-point contact and uniform force distribution.

[0036] The introduction of slide 5 significantly improves the adaptability and operational accuracy of the entire intelligent hydraulic support device for derrick assembly and disassembly in oil drilling under complex working conditions. It not only enhances the system's tolerance to lateral positional deviations of the derrick, but also forms a multi-level collaborative support mechanism with the existing adaptive structure of contact frame 4—slide 5 is responsible for positioning, and contact frame 4 is responsible for engagement. This not only shortens the preparation time for derrick assembly and reduces reliance on the accuracy of lifting equipment, but also further improves the reliability and safety of the support process, making it particularly suitable for large, heavy, or high-precision derrick installation scenarios.

[0037] Example 4: Reference Figures 1-5 In addition to possessing all the technical solutions of the above embodiments, the embodiments of this utility model further possess the following technical solutions: The intelligent hydraulic support device for disassembling and assembling derricks in oil drilling also includes a sensing unit, which is suitable for detecting the position of the derrick to be supported, so that the slide 5 can drive the support part of the contact frame 4 to actively correspond with the position to be supported.

[0038] In this embodiment, the sensing unit is configured to detect the position of the derrick in real time. Specifically, it may include a vision sensor to acquire the actual coordinates, attitude, and contour information of the bottom of the derrick in space. After processing by the control system, this data can accurately calculate the relative deviation between the current supporting part of the contact frame 4 and the ideal supporting point of the derrick.

[0039] Based on this deviation information, the control system can drive the slide table 5 to move precisely laterally along the second horizontal direction Y, allowing the contact frame 4 to actively adjust its position within a preset limit range, ensuring that its supporting part is accurately aligned with the area to be supported by the derrick. This process requires no manual intervention, significantly improving alignment efficiency and accuracy. Especially in complex situations such as manufacturing tolerances, transportation deformation, or on-site installation tilting of the derrick, the real-time feedback from the sensing unit and the dynamic response capability of the slide table 5 can effectively compensate for various spatial deviations, ensuring a high success rate for the supporting action.

[0040] Furthermore, the sensing unit can also be linked with the height adjustment mechanism of the lifting frame 2 to achieve collaborative positioning in three-dimensional space. While the slide 5 completes lateral alignment, the lifting frame 2 simultaneously adjusts its height, ensuring the supporting surface precisely aligns with the bottom of the derrick in the vertical direction. Combined with the adaptive rotation capability of the contact frame 4, the entire support system forms a closed-loop control logic of "perception—decision—execution—adaptive alignment," which not only significantly shortens the preparation cycle for derrick assembly but also significantly reduces the risk of structural stress concentration, localized crushing, or slippage caused by misalignment. Simultaneously, because the entire process is recordable and traceable, it also provides a data foundation for subsequent quality control and digital construction management. Overall, the introduction of the sensing unit upgrades the intelligent hydraulic support device for oil drilling derrick assembly and disassembly from a simple mechanical support platform into an intelligent assembly auxiliary equipment with environmental perception, autonomous decision-making, and flexible execution capabilities, greatly improving the safety, efficiency, and accuracy of derrick installation operations.

[0041] Example 5: Reference Figures 1-5 In addition to possessing all the technical solutions of the above embodiments, the embodiments of this utility model further possess the following technical solutions: The walking device 3 includes a first moving part 31, which is located on both sides of the frame 1 and can drive the frame 1 to move laterally along the first horizontal direction X.

[0042] The walking device 3 also includes a second moving part 32, which is located on both sides of the frame 1 and can drive the frame 1 to move laterally along the second horizontal direction Y. Both the first moving part 31 and the second moving part 32 can be configured as a track drive mechanism.

[0043] Under the action of the first moving member 31, the system can achieve lateral movement along the first horizontal direction X, and can turn and turn around by the speed difference between the two sets of first moving members 31.

[0044] With the combined action of the first moving part 31 and the second moving part 32, the system can achieve horizontal plane apex movement without relying on the rotational speed difference between the two sets of first moving parts 31 and the two sets of second moving parts 32, thereby greatly improving the system's flexibility and convenience.

[0045] In this embodiment, the dual-axial drive structure of the first moving part 31 and the second moving part 32 significantly enhances the mobility and positioning capability of the whole machine in the horizontal plane. Both can adopt track drive mechanism, which not only provides good ground adhesion and obstacle crossing ability, but also maintains stable operation in soft, uneven or restricted well site environment.

[0046] The first moving component 31 not only supports the linear lateral movement of the entire machine along the first horizontal direction X, but also enables the system to turn or even turn around on the spot by adjusting the speed difference between the left and right first moving components 31, thus flexibly adjusting the orientation in confined spaces. The second moving component 32, on the other hand, gives the system the ability to move independently along the second horizontal direction Y, allowing it to directly approach or move away from one side of the derrick without relying on steering.

[0047] When the first moving part 31 and the second moving part 32 work together, the system can complete oblique movement or in-situ translation without relying on the speed difference control between the tracks on each side, so that the lifting frame 2 system can accurately reach the target position in a short path and in an efficient manner.

[0048] This biaxial tracked drive architecture, together with the aforementioned slide 5, contact frame 4, and sensing unit, forms a multi-layered positioning system: the walking device 3 is responsible for large-scale, highly mobile site-level positioning; the slide 5 enables the contact frame 4 to fine-tune its alignment in the second horizontal direction Y; the contact frame 4 itself achieves adaptive contact with the derrick surface through a hinge and the second swing head 42 structure; and the sensing unit provides position feedback and closed-loop control throughout the process. Thus, the entire system possesses high precision, high adaptability, and high automation levels across the three scales of macroscopic movement, mesoscopic alignment, and microscopic contact.

[0049] In summary, by introducing mutually perpendicular first and second moving parts 32 and adopting a tracked drive system, this intelligent hydraulic support device for assembling and disassembling derricks in oil drilling not only significantly improves the flexibility of passage and positioning in complex operating environments, but also significantly simplifies the operation process, reduces reliance on auxiliary equipment and manual intervention, and provides solid technical support for the efficient, safe, and precise assembly of derricks.

[0050] Example 6: Reference Figures 1-5 In addition to possessing all the technical solutions of the above embodiments, the embodiments of this utility model further possess the following technical solutions: The intelligent hydraulic support device for disassembling and assembling derricks in oil drilling also includes multiple sets of first telescopic drive components 6 and second telescopic drive components 7, all of which extend vertically. The two ends of the first telescopic drive component 6 are respectively fixedly connected to the walking device 3 and the frame 1, and the two ends of the second telescopic drive component 7 are respectively fixedly connected to the lifting frame 2 and the frame 1.

[0051] In this embodiment, the intelligent hydraulic support device for disassembling and assembling derricks in oil drilling is further configured with multiple sets of vertically extending first telescopic drive members 6 and second telescopic drive members 7, which are used to independently control the vertical position of the walking device 3 and the lifting frame 2 relative to the frame 1, thereby realizing reliable switching between the walking state and the stopped state, as well as precise adjustment of the derrick support height.

[0052] Specifically, the two ends of the first telescopic drive member 6 are fixedly connected between the walking device 3 and the frame 1, respectively. Its main function is to drive the walking device 3 to move vertically. When the system needs to move, the first telescopic drive member 6 extends, lowering the walking device 3 to the ground so that it bears the weight of the entire machine and enters the walking state. When the system reaches the target position, the first telescopic drive member 6 retracts, raising the walking device 3 to a position higher than the bottom support feet of the frame 1, so that the support feet contact the ground and bear the weight independently, and the system thus enters a stable and reliable stopped state. This structure ensures that the walking device 3 is completely detached from the load-bearing path when not moving, avoiding creep, deformation or accidental rolling of the tracks or wheel system under heavy load, and significantly improving operational safety.

[0053] The second telescopic drive component 7 is connected between the lifting frame 2 and the frame 1, and is used to precisely adjust the vertical height of the lifting frame 2. During the assembly of the derrick, the control system can drive the second telescopic drive component 7 to extend or retract based on the height information of the bottom of the derrick fed back by the sensing unit, so that the support part on the contact frame 4 is precisely aligned with the position to be supported on the derrick. This drive method not only provides a large stroke and high load capacity, but also enables millimeter-level height fine adjustment, meeting the requirements of high-precision assembly.

[0054] The first telescopic drive component 6 and the second telescopic drive component 7 can be arranged symmetrically to effectively balance the load, prevent tilting or jamming caused by uneven load during lifting, and further improve the stability and reliability of the system operation.

[0055] Example 7: Reference Figures 1-5 In addition to possessing all the technical solutions of the above embodiments, the embodiments of this utility model further possess the following technical solutions: The intelligent hydraulic support device for disassembling and assembling derricks in oil drilling also includes multiple sets of sliding sleeve assemblies 8. The two ends of the sliding sleeve assembly 8 are respectively fixedly connected to the lifting frame 2 and the frame 1 to serve as guide components when the lifting frame 2 is raised or lowered.

[0056] The intelligent hydraulic support device for disassembling and assembling derricks in oil drilling also includes a locking component 9, which is fixedly connected to the frame 1 and is suitable for selectively locking the sliding sleeve assembly 8. The locking component 9 includes a third telescopic drive 91 and a locking pin 92. The third telescopic drive 91 is horizontally fixedly connected to the frame 1, and the locking pin 92 is fixedly connected to the telescopic part of the third telescopic drive 91. The sliding sleeve assembly 8 is provided with a locking hole 80, and the locking pin 92 can selectively engage with the locking hole 80 under the drive of the third telescopic drive 91 to limit the lifting of the lifting frame 2.

[0057] In this embodiment, the intelligent hydraulic support device for dismantling and assembling derricks in oil drilling is further enhanced with multiple sets of sliding sleeve assemblies 8 and locking assemblies 9, significantly improving the guiding accuracy and operational safety of the lifting frame 2 during vertical movement. The sliding sleeve assembly 8 is rigidly connected at both ends to the lifting frame 2 and the frame 1, extending vertically to form a guiding mechanism for the lifting movement of the lifting frame 2. Its structure includes an outer cylinder 81 and an inner rod 82, which not only effectively constrains the lateral sway and torsion of the lifting frame 2 during lifting, but also withstands the eccentric load, lateral force, and vibration load transmitted by the derrick, ensuring that the entire support platform maintains good alignment and structural stability during dynamic adjustment and static support.

[0058] Based on this, the system introduces a locking component 9 to reliably lock the lifting frame 2 after it reaches the target height, preventing accidental settlement due to hydraulic leakage, drive failure, or external disturbance. This locking component 9 is fixed to the frame 1 and mainly includes a third telescopic drive 91 and a locking pin 92: the third telescopic drive 91 is horizontally mounted on the frame 1 structure, and its telescopic end is connected to the locking pin 92; the outer cylinder 81 and inner rod 82 of the sliding sleeve assembly 8 are respectively provided with locking holes 80 that match the locking pin 92. When the lifting frame 2 is adjusted to the required height, the control system drives the third telescopic drive 91 to extend, pushing the locking pin 92 into the locking hole 80 on the sliding sleeve assembly 8, thereby mechanically restricting the vertical displacement of the lifting frame 2. Even if the second telescopic drive 7 fails or is unloaded, the locking pin 92 can still independently bear all or part of the derrick load, forming redundant safety protection.

[0059] This locking mechanism boasts advantages such as rapid response, reliable operation, and convenient unlocking. When height readjustment is required, the third telescopic drive 91 retracts, disengaging the locking pin 92 from the locking hole 80, thus restoring the free movement of the lifting frame 2. Multiple sets of locking components 9 can be arranged one-to-one with multiple sets of sliding sleeve components 8 to achieve multi-point synchronous locking, further improving load uniformity and anti-overturning capability. Furthermore, multiple locking holes 80 can be vertically spaced along the sliding sleeve components 8, supporting mechanical locking at different height positions and enhancing the system's adaptability to various working conditions and specifications of derricks.

[0060] In summary, the synergistic introduction of the sliding sleeve assembly 8 and the locking assembly 9 not only provides the lifting frame 2 with high-precision and high-rigidity motion guidance, but also constructs a mechanical safety barrier independent of the main drive system. This design significantly improves the system's reliability under prolonged support, sudden power outages, or extreme operating conditions, effectively preventing the derrick from shifting, tilting, or even collapsing due to support failure. Combined with the aforementioned omnidirectional travel, sensor module alignment, adaptive support, and sensor closed-loop control, this system has formed a derrick assembly and support solution that combines high mobility, high precision, high safety, and high reliability, fully meeting the stringent requirements of modern oil and gas fields, offshore platforms, and other complex engineering scenarios for the rapid, safe, and intelligent installation of heavy structures.

[0061] Specifically, a first moving part 31 and a second moving part 32 can correspond to two first telescopic driving parts 6, and the lifting frame 2 can correspond to two telescopic driving parts and four sliding sleeve assemblies 8 to ensure the stability and tracking of each component during lifting.

[0062] Example 8: Reference Figures 1-5 In addition to possessing all the technical solutions of the above embodiments, the embodiments of this utility model further possess the following technical solutions: The intelligent hydraulic support device for oil drilling derricks also includes a load detection unit, which is fixedly connected to the support section and suitable for detecting the load on the support section, significantly enhancing its intelligent sensing and safety control capabilities during derrick support. The load detection unit uses high-precision pressure sensors, strain gauges, or weighing modules to monitor the actual load borne by each support point in real time and accurately. Since each contact frame 4 in the system is equipped with two sets of V-shaped second swing heads 42, and each set of second swing heads 42 has hinged support plates 43 at both ends, forming up to four independent support surfaces, multiple load detection units can be arranged accordingly to achieve multi-point, distributed load sensing of the derrick support status.

[0063] By collecting load data from each support component in real time, the control system can dynamically assess whether the stress distribution of the derrick is uniform and whether there are abnormalities such as uneven loading or single-point overload. For example, if the load detected on a certain support surface is significantly higher than that at other locations, the system can determine that the derrick may have problems such as tilting, local deformation, or misalignment during installation, and issue a timely warning, or even automatically suspend lifting or traveling movements to avoid structural damage or instability caused by uneven stress. In scenarios where multiple derricks operate collaboratively, the load data between each device can also be shared through a communication network to achieve balanced load distribution and synchronous control, further improving the safety and coordination of the overall operation.

[0064] It can be understood that, except for conflicting parts, the above embodiments 1-8 can be freely combined to form other embodiments of this utility model.

[0065] In the description of this utility model, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0066] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., 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. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0067] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is 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 "beneath" the second feature can mean that the first feature is 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.

[0068] The term "comprising" or any other similar term is intended to cover non-exclusive inclusion, such that a process, article, or apparatus / device that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to those processes, articles, or apparatus / devices.

[0069] The technical solution of this utility model has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
