Description

TECHNICAL FIELD

[0001] The application relates to a hydraulic cylinder adjusting device, a base assembly and a method for multi-condition shared hydraulic cylinder lifting, and belongs to the technical field of oil drilling rigs. BACKGROUND

[0002] The rotary drilling rig using hydraulic cylinder lifting is widely applied in drilling operations due to the advantages of high lifting efficiency and convenient operation brought by hydraulic driving. The lifting-up and lifting-down process of the drilling rig mast and base can be accurately controlled through the hydraulic control system, and the single lifting time is greatly shortened, but at the same time, the installation precision of the hydraulic cylinder is strictly required. If the installation precision of the hydraulic cylinder is insufficient, the cylinder body is prone to uneven stress, causing problems such as body wear, lifting action jamming, and drilling rig structure deflection, and even causing operation interruption.

[0003] The hydraulic cylinder itself is heavy, and the traditional installation needs to rely on auxiliary equipment such as cranes and forklifts for lifting and positioning, which is difficult to operate and low in efficiency. Especially during the lifting process, the angle of the hydraulic cylinder is prone to shift due to vibration and load changes, and more importantly, the hydraulic cylinder cannot be adjusted in real time during the extension and retraction process, and accurate installation can only be achieved by repeated disassembly and adjustment, which is time-consuming and labor-intensive.

[0004] Although the patent No. CN201474606U discloses a device for transporting and installing the mast lifting hydraulic cylinder, the device fixes the hydraulic cylinder through a hoop and a bracket, and connects the hydraulic cylinder and the mast through the lifting device. However, the device has obvious limitations: the installation position is fixed, and it is only suitable for hydraulic cylinder transportation and single lifting of the mast, and cannot adapt to different working conditions of the shared hydraulic cylinder for alternating lifting of the mast and the base, and lacks the ability to continuously right the hydraulic cylinder during extension and retraction, and cannot solve the problem of deviation in dynamic operation. SUMMARY

[0005] The application aims to provide a hydraulic cylinder adjusting device, a base assembly and a method for multi-condition shared hydraulic cylinder lifting, which can solve the technical problems that the existing rotary drilling rig hydraulic cylinder installation relies on large auxiliary equipment, the debugging is time-consuming, the operation safety is low, and the existing adjusting device cannot adapt to the multiple lifting conditions of the shared hydraulic cylinder for the mast and the base, and lacks dynamic righting ability.

[0013] Alternatively, the support frame may include a semi-circular bracket, the bottom of which is hinged to the support platform.

[0014] Alternatively, a rubber pad may be attached to the inner side of the semi-circular bracket.

[0015] A base assembly for lifting a hydraulic cylinder under multiple working conditions includes a base, on which a hydraulic cylinder and two sets of hydraulic cylinder adjustment devices as described above are provided, the two sets of hydraulic cylinder adjustment devices being respectively located on the front and rear sides of the hydraulic cylinder.

[0016] A method for lifting using a shared hydraulic cylinder under multiple operating conditions includes the following steps: S1. The lower end of the hydraulic cylinder is connected to the base. The hydraulic cylinder is placed against the support frame of the front hydraulic cylinder adjustment device. The lifting device of the front hydraulic cylinder adjustment device is operated to lift and change the tilt angle of the hydraulic cylinder until the lug plate at the piston rod end of the hydraulic cylinder is coaxial with the hole of the hoisting lug plate of the derrick. The hydraulic cylinder and the derrick are connected with a pin. The derrick hoisting program is started.

Detailed Implementation

[0021] The present invention will now be described in detail with reference to the accompanying drawings.

[0022] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0023] Example 1 A hydraulic cylinder adjustment device for multi-condition shared hydraulic cylinder lifting, such as Figures 1-8 As shown, it includes a fixed seat 1 on a base 7, an mounting seat 2 connected to the upper part of the fixed seat 1, a telescopic rod 3 connected to the mounting seat 2 in a height-adjustable manner, a support platform at the top of the telescopic rod 3, a lifting device 5 between the mounting seat 2 and the support platform, and the support platform is lifted and lowered by the lifting device 5. A support frame 4 for supporting the hydraulic cylinder 10 is hinged on the support platform.

[0024] In this design, the fixed base 1 connects the overall structure to the base 7, preventing loosening or displacement during operation. The mounting base 2 connects to the fixed base 1, serving as the load-bearing component of the lifting structure. It provides a stable support foundation for the telescopic rod 3 and the lifting device 5, ensuring the overall structure's installation stability and operational safety. The lifting of the telescopic rod 3 drives the support frame 4 to rise and fall, changing the position of its contact point with the hydraulic cylinder 10, enabling the hydraulic cylinder 10 to rotate slightly around its bottom, ensuring precise matching of the installation position. The lifting device 5 provides power for the lifting of the support platform. Specifically, the lifting device 5 can be a jack, allowing for precise manual length adjustment. Compared to using a hydraulic cylinder, this provides a faster power response and more precise control. The support platform provides a bearing surface for the telescopic rod 3 and connects with the lifting device 5, achieving a uniform distribution of force and load, adapting to various load conditions. The support frame 4 drives the hydraulic cylinder 10 to make minor angle adjustments during the docking process, and simultaneously supports and straightens the hydraulic cylinder 10 during its extension and retraction. It is hinged to the top of the telescopic rod 3, allowing it to rotate back and forth to match the relative angle of the hydraulic cylinder 10 during rotation, ensuring stable contact, uniform pressure distribution, and avoiding localized stress concentration. In this text, the front side is the side where the derrick 8 is placed; the derrick 8 rotates from front to back to achieve lifting, while the left and right directions are the left and rear sides in the forward-backward direction.

[0025] This solution uses the lifting device 5 to drive the telescopic rod 3 to fine-tune the angle of the hydraulic cylinder 10, ensuring that the piston rod end lug of the hydraulic cylinder 10 is coaxially aligned with the lifting lug hole of the derrick 8 or base 9. This eliminates the need for large equipment such as cranes and forklifts, reducing operating costs and shortening installation and commissioning time. Furthermore, the hydraulic cylinder adjustment device 6 is located on the base 7, between the base 7 and the hydraulic cylinder 10, allowing for angle adjustment of the hydraulic cylinder 10 from a low position, avoiding the risks of high-altitude auxiliary operations. Moreover, the hydraulic cylinder 10 is always aligned by the support frame 4 throughout its extension and retraction, effectively preventing uneven force distribution due to cylinder misalignment, reducing wear and operational interruptions caused by installation deviations, and extending the service life of the hydraulic cylinder 10.

[0026] Example 2 Based on Example 1, as a further solution, such as Figure 1 , 2As shown in Figure 3, the mounting base 2 includes two sets of support frames arranged parallel to each other in the left-right direction. The two sets of support frames are connected by a crossbeam 26. Each set of frames includes a sleeve 24. The telescopic rod 3 includes two insert rods 31, each insert rod 31 is inserted into a sleeve 24, and the insert rod 31 can move along the sleeve 24. The tops of the two insert rods 31 are connected by a support platform. A lifting device 5 is provided between the support platform and the crossbeam 26. The two sets of support frames can provide coordinated support and limit, and evenly distribute the overall load to each mounting base 2, avoiding local overload problems and ensuring the structural stability after installation. The crossbeam 26 and the support platform can connect the two sets of support frames and insert rods 31 into one unit, ensuring the synchronous movement of the components and avoiding overall movement disorder caused by the movement deviation of a single component; and also providing a force plane for the lifting device 5, distributing the load to the left and right support frames, reducing stress concentration on a single rod. The insert rod 31 and sleeve 24 provide precise and stable guidance for lifting and moving, ensuring the straightness of the movement trajectory, reducing offset errors, and ensuring smooth and stable operation.

[0027] Example 3 Based on Example 2, as a further solution, such as Figure 1 , 2 As shown in Figure 4, the bottom of the mounting base 2 is provided with at least two single-ear seats 21, and the fixing base 1 is a double-ear seat, with each fixing single-ear seat 21 connected to a double-ear seat. The components are fixed by connecting with pins, eliminating the need for additional complex fixing structures and cumbersome positioning steps. No professional positioning tools are required, allowing for rapid installation, shortening on-site construction time, and facilitating disassembly of the device to other bases 7. Furthermore, the pins maintain a stable stress state and possess excellent load-bearing capacity.

[0028] Example 4 Based on embodiments two and three, as a further solution, the sleeve 24 and the insertion rod 31 are provided with corresponding inner and outer fixing holes, and the sleeve 24 and / or the insertion rod 31 are provided with multiple fixing holes. After the lifting device 5 is adjusted to a suitable position, the height can be locked by inserting a pin into the corresponding fixing hole, avoiding damage to the lifting device 5 due to prolonged stress, extending the overall service life of the components, and reducing the frequency and cost of subsequent maintenance.

[0029] Example 5 Based on embodiments two to four, as a further solution, such as Figure 2As shown, each frame includes a sleeve 24, at least one diagonal brace 23, and at least one connecting rod 22. The upper parts of the diagonal brace 23 and the sleeve 24 are directly connected, and the lower parts of the diagonal brace 23 and the sleeve 24 are connected through the connecting rod 22. The bottoms of the diagonal brace 23 and the sleeve 24 are connected to the fixed seat 1. Specifically, at least one triangular structure is formed between the sleeve 24, the diagonal brace 23, and the connecting rod 22. The triangle will not deform under stress and can effectively disperse external forces. By evenly distributing the load to each node and member, deformation or fracture caused by local stress concentration is avoided, and the self-weight is reduced while achieving high strength and rigidity. Specifically, the bottom of the diagonal brace 23 and the front or rear side of its top are designed to enhance the load-bearing capacity in the front-rear direction, corresponding to the tilting direction of the hydraulic cylinder 10 and the tilting direction of the derrick 8. The bottom of the diagonal brace 23 and the sleeve 24 are provided with a single-ear seat 21 according to Embodiment 2.

[0030] Example 6 Based on embodiments three to five, as a further solution, such as Figure 2 As shown, a baffle 25 is provided on the crossbeam 26, located on the front and / or rear side of the bottom of the lifting device 5. When the lifting device 5 is placed on the crossbeam 26, the baffles 25 located at the front and rear of the crossbeam 26 prevent the lifting device 5 from slipping off the crossbeam 26 during lifting. Compared to directly fixing the lifting device 5 to the crossbeam 26, the assembly process is faster, and existing lifting devices 5 can be placed directly without modification.

[0031] Example 7 Based on embodiments one through six, as a further solution, such as Figure 1 , 3 As shown in Figure 4, a connecting lug 33 is provided on the support platform, and a connecting lug 41 is provided at the bottom of the support frame 4. The connecting lug 41 and the connecting lug 33 are hinged together. A limiting plate 34 is provided on the front and / or rear side of the connecting lug 33 to restrict the rotation range of the connecting lug 41. The connection between the connecting lug 41 and the connecting lug 33 can ensure that the support frame 4 can rotate flexibly around the hinge point, cooperating with the rotation of the hydraulic cylinder 10, and can self-adapt by fine-tuning the force position when in contact with the hydraulic cylinder 10. Among them, the connecting lug 41 and the connecting lug 33 are hinged by a pin. The double positioning point of the connecting lug 33 can constrain the displacement and deflection of the pin, ensuring that the connecting lug 41 only has rotational freedom. The limiting plate 34 provided on the front and / or rear side of the connecting lug 33 can constrain the rotation of the support frame 4 within a safe range and prevent loss of support function due to excessive rotation. Among them, H-beam 36 is provided with first stiffening plates 32 on both sides inside the H-beam 36; and a second stiffening plate 35 is connected between the lower part of the limiting plate 34 and the upper surface of the support platform.

[0032] Example 8 Based on Examples 1 to 7, as a further solution, such as Figure 4 As shown, the support frame 4 includes a semi-circular bracket 42, the bottom of which is hinged to the support platform. The semi-circular bracket 42 can adapt to the shape of the hydraulic cylinder 10, allowing the pressure on the contact surface to be evenly distributed, avoiding local stress concentration, reducing wear or damage to components due to uneven force, and making the relative sliding of the contact surface smoother during movement. The axis and inner diameter of the semi-circular bracket 42 are adapted to the hydraulic cylinder 10.

[0033] Example 9 Based on Example 8, as a further solution, such as Figure 4 As shown, a rubber pad 44 is connected to the inner side of the semi-circular bracket 42. The rubber pad 44 is made of soft and elastic material, which can closely conform to contact surfaces with different flatness, further enhancing the contact effect, providing stable support, and reducing rigid collisions between contact surfaces. Specifically, the rubber pad 44 is connected to the semi-circular bracket 42 by screws 43.

[0034] Example 10 A base assembly for multi-condition shared hydraulic cylinder lifting, such as Figures 5-8 As shown, it includes a base 7, on which a hydraulic cylinder 10 and two sets of hydraulic cylinder adjustment devices 6 as described above are provided. The two sets of hydraulic cylinder adjustment devices 6 are respectively located on the front and rear sides of the hydraulic cylinder 10.

[0035] In the complete lifting operation cycle of the derrick 8 and the base 9, the alternating use of two hydraulic cylinder adjustment devices 6 enables the installation, adjustment and full alignment of the hydraulic cylinder 10 under different working conditions. The entire process is free from large auxiliary equipment such as cranes, simplifying the operation process, shortening the installation and debugging time, and avoiding the risks of high-altitude operations and installation deviations, thus significantly improving operational safety and equipment reliability.

[0036] Example 11 A method for lifting using a shared hydraulic cylinder under multiple operating conditions includes the following steps: S1, such as Figure 5 As shown, the lower end of the hydraulic cylinder 10 is connected to the base 7. The hydraulic cylinder 10 is placed against the support frame 4 of the front hydraulic cylinder adjustment device 6. The lifting device 5 of the front hydraulic cylinder adjustment device 6 is operated to lift and change the tilt angle of the hydraulic cylinder 10 until the piston rod end ear plate of the hydraulic cylinder 10 is coaxial with the lifting ear plate hole of the derrick 8. The hydraulic cylinder 10 and the derrick 8 are connected by a pin, and the lifting program of the derrick 8 is started. The hydraulic cylinder adjustment device 6 continues to straighten and support the hydraulic cylinder 10 until the hydraulic cylinder 10 is lifted and detached from the support frame 4 with the derrick 8, thus completing the initial lifting assistance of the derrick 8. S2, such as Figure 6As shown, after the derrick 8 is raised to the position, when the hydraulic cylinder 10 needs to be retracted, the rear hydraulic cylinder adjustment device 6 and the lifting device 5 are operated to adjust the length of the telescopic rod 3 so that the support frame 4 fits against the outer wall of the hydraulic cylinder 10. The pin connecting the hydraulic cylinder 10 and the derrick 8 is removed. The hydraulic cylinder 10 retraction program is started. During the entire retraction process, the hydraulic cylinder adjustment device 6 keeps the retraction angle of the hydraulic cylinder 10 stable through the support frame 4 to avoid deviation until the hydraulic cylinder 10 returns to its initial state. S3, such as Figure 7 As shown, switch to the lifting mode of base 9, operate the rear hydraulic cylinder adjustment device 6 and lifting device 5, adjust the length of telescopic rod 3 until the piston rod end ear plate of hydraulic cylinder 10 is coaxial with the lifting ear plate hole of base 9, connect hydraulic cylinder 10 and base 9 with pin, and start the lifting program of base 9. S4, such as Figure 8 As shown, after the base 9 is raised to the position, when the hydraulic cylinder 10 needs to be retracted, operate the lifting device 5 of the front hydraulic cylinder adjustment device 6 to adjust the length of the telescopic rod 3 so that the support frame 4 fits against the outer wall of the hydraulic cylinder 10, and remove the pin connecting the hydraulic cylinder 10 and the base 9; start the hydraulic cylinder 10 retraction program. During the entire retraction process, the hydraulic cylinder adjustment device 6 keeps the retraction angle of the hydraulic cylinder 10 stable through the support frame 4 to avoid deviation until the hydraulic cylinder 10 returns to its initial state.

[0037] Based on this embodiment, after the lifting device 5 is adjusted to a suitable position, a pin can be inserted into the corresponding fixing holes of the sleeve 24 and the insertion rod 31 to prevent the lifting device 5 from being subjected to force for a long time.
