Description

Technical Field

[0001] The invention belongs to the field of offshore oil and gas platforms, and particularly relates to a hydraulic steel pile construction platform. Background Art

[0002] Steel piles are an important supporting part of the pile foundation fixed offshore platform structure. Currently, during the offshore installation process of jacket platforms, the construction process of steel piles includes: pile head cutting, grinding, welding, and inspection. Before construction, a large number of scaffolders are mainly used to manually build a scaffolding to make an operating platform, and then riveters, welders, and inspectors are mobilized to carry out operations such as cutting, grinding, welding, and inspection on the platform. Not only is the safety risk high, but the construction speed is also very slow.

[0003] Analyzing the traditional scaffolding erection process reveals the existing problems. First, the height of the scaffolding cannot be accurately controlled and adjusted arbitrarily. Second, in the conventional construction process of Bohai standard jacket platforms, each pile leg has at least three sections of steel piles, and there is a large amount of workload for cutting, grinding, and welding the pile heads with two weld joints. At the same time, to meet the width requirement of the hammer sleeve of the pile driving hammer, the jacket platform needs to be repeatedly demolished, thus consuming a large amount of time. Third, in harsh conditions such as high-altitude operations and hot weather at sea, there are more safety risks in the cumbersome work.

[0004] Therefore, there is an urgent need to design a hydraulic steel pile construction platform to solve the problems of inability to freely adjust, easy repeated demolition, and safety risks. Summary of the Invention

[0005] To solve the technical problems of inability to freely adjust, easy repeated demolition, and safety risks mentioned in the background art, a hydraulic steel pile construction platform is provided.

[0006] To achieve the above object, the specific technical solution of a hydraulic steel pile construction platform of the present invention is as follows: A hydraulic steel pile construction platform includes a base, a driving mechanism is arranged on the base, the output end of the driving mechanism is connected to a working platform, both the working platform and the base are provided with processing positions, and a clamping mechanism is arranged at the bottom of the working platform. The clamping mechanism is used to clamp the workpiece located at the processing position to limit the relative displacement between the working platform and the workpiece.

[0007] Further, the hydraulic steel pile construction platform further includes a support frame, the support frame is arranged between the working platform and the base, an avoidance hole is arranged on the support frame, the avoidance hole is communicated with the processing position, and the workpiece can pass through the avoidance hole and the processing position in sequence.

[0008] Further, the avoidance hole is circular.

[0009] Further, the clamping mechanism includes clamping jaws and a driving member. The driving member is disposed below the support frame, and the clamping jaws are disposed at the output end of the driving member. The driving member is configured to drive the clamping jaws to move towards or away from the workpiece.

[0010] Further, both the base and the working platform are configured as rectangles. The machining position is disposed at the central positions of the rectangular base and the rectangular working platform, and the clamping mechanisms are disposed at the four corners of the rectangular working platform.

[0011] Further, two sets of clamping mechanisms are provided, and the two sets of clamping mechanisms are symmetrically disposed with respect to the axis of symmetry of the rectangular working platform.

[0012] Further, the working platform includes a support table and a guardrail. The guardrail is disposed on the peripheral side of the support table and is connected to the support table.

[0013] Further, the guardrail is detachably connected to the support table.

[0014] Further, the hydraulic steel pile construction platform further includes a lifting module. The lifting module is disposed between the working platform and the base, and the lifting module is configured to be able to guide the working platform to rise or fall relative to the base.

[0015] Further, the lifting module includes two sets of lifting components arranged crosswise. The middle parts of the two sets of lifting components cross and are hinged to each other, and the two ends of each set of lifting components are respectively hinged to the working platform and the base.

[0016] The hydraulic steel pile construction platform of the present invention has the following advantages: The hydraulic steel pile construction platform can preset different platform lifting speeds and lifting height values according to the different actual construction requirements of different workpieces, ensuring the comfort of workers during construction to achieve the highest construction efficiency; when the construction platform rises to the ideal working height, the clamping mechanisms located below the working platform are successively extended. After all the multiple clamping mechanisms are extended, the construction platform will be firmly fixed to the workpiece, avoiding the shaking of the upper and lower platforms under the influence of sea waves and currents after rising to a certain height, and also enabling the working platform to be directly opposite the center of the workpiece. This not only greatly improves the safety of the operation but also ensures the quality of the construction. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some but not all of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Those skilled in the art can understand that although some embodiments herein include some features included in other embodiments rather than other features, the combination of the features of different embodiments means that it is within the scope of the present invention and forms different embodiments. For example, in the claims, any one of the claimed embodiments can be used in any combination.

[0021] The following refers to the attached Figure 1 to the attached Figure 2 Describe the hydraulic steel pile construction platform of the present invention.

[0022] This embodiment provides a hydraulic steel pile construction platform, as Figure 1 and Figure 2 shown. The hydraulic steel pile construction platform includes a base 1, a driving mechanism 2 is arranged on the base 1, the output end of the driving mechanism 2 is connected to a working platform 3, processing positions 4 are arranged on both the working platform 3 and the base 1, and a clamping mechanism 5 is arranged at the bottom of the working platform 3. The clamping mechanism 5 is used to clamp the workpiece located at the processing position 4 to limit the relative displacement between the working platform 3 and the workpiece.

[0023] This hydraulic steel pile construction platform can preset different platform lifting speeds and lifting height values according to the different actual construction requirements of different workpieces, ensure the comfort of workers during construction, and achieve the highest construction efficiency; when the construction platform rises to the ideal working height, the clamping mechanisms 5 located below the working platform 3 extend successively. After all the clamping mechanisms 5 are extended, the construction platform and the workpiece will be firmly fixed, avoiding the shaking of the upper and lower platforms under the influence of sea waves and currents after rising to a certain height, and also making the working platform 3 face the center of the workpiece. This not only greatly improves the safety of the operation, but also ensures the quality of the construction.

[0024] It should be noted that in this embodiment, the above-mentioned workpiece is a steel pile.

[0025] Further, as Figure 2 shown, the hydraulic steel pile construction platform further includes a support frame 6. The support frame 6 is disposed between the working platform 3 and the base 1. An avoidance hole 61 is provided on the support frame 6. The avoidance hole 61 communicates with the processing position 4, and the workpiece can sequentially pass through the avoidance hole 61 and the processing position 4.

[0026] Preferably, the avoidance hole 61 is circular.

[0027] Further, the clamping mechanism 5 includes a clamping jaw 51 and a driving member 52. The driving member 52 is disposed below the support frame 6. The clamping jaw 51 is disposed at the output end of the driving member 52. The driving member 52 is used to drive the clamping jaw 51 to move towards or away from the workpiece.

[0028] Optionally, the driving member 52 is a push hydraulic cylinder. After the construction platform is lifted to the ideal working height, the four push hydraulic cylinders located below the platform will be successively extended under the action of hydraulic pressure. The maximum thrust of each cylinder reaches 15t. After all four hydraulic cylinders are extended, the construction platform will be firmly fixed to the pile leg, avoiding the upper and lower platforms from shaking under the influence of sea waves and currents after rising to a certain height, and also making the platform directly face the center of the steel pile. This not only greatly improves the safety of the operation, but also ensures the construction quality.

[0029] Further, both the base 1 and the working platform 3 are set as rectangles. The processing position 4 is disposed at the center positions of the rectangular base 1 and the rectangular working platform 3. The clamping mechanism 5 is disposed at the four corners of the rectangular working platform 3.

[0030] Further, the clamping mechanism 5 is set as two groups, and the two groups of clamping mechanisms 5 are symmetrically disposed with respect to the axis of symmetry of the rectangular working platform 3.

[0031] Further, the working platform 3 includes a support table 31 and a guardrail 32. The guardrail 32 is disposed on the peripheral side of the support table 31 and is connected to the support table 31; optionally, the guardrail 32 is detachably connected to the support table 31, so as to achieve quick disassembly and assembly. By designing a guardrail 32 with quick plug-in and unplugging, during construction preparation, personnel and construction tools can board the construction platform without obstacles. After the preparation is completed, install the guardrail 32, and then the construction tabletop can be lifted to carry out subsequent construction operations.

[0032] As a preferred implementation manner, to avoid problems such as water accumulation at the quick plug-in interface causing corrosion of the guardrail 32 and the buckle, a water leakage hole is opened at the quick interface to quickly drain rainwater, seawater, etc. during construction.

[0033] Further, the hydraulic steel pile construction platform further includes a lifting module 7. The lifting module 7 is disposed between the working platform 3 and the base 1. The lifting module 7 is configured to be able to guide the working platform 3 to rise or fall relative to the base 1.

[0034] It can be understood that the above-mentioned lifting module 7 can preset different platform lifting speeds and lifting height values through the PLC control unit in the electric control system, and can also arbitrarily adjust the lifting height of the construction tabletop through the control panel or remote control, ensuring the comfort of workers during construction to achieve the highest construction efficiency.

[0035] Furthermore, the lifting module 7 includes two sets of lifting components 71 arranged crosswise. The middle parts of the two sets of lifting components 71 cross and are hinged to each other. The two ends of each set of lifting components 71 are respectively hinged to the working platform 3 and the base 1.

[0036] Optionally, the lifting module 7 can be replaced with a scissor structure in the prior art, and the lifting component 71 is a scissor arm.

[0037] Optionally, the driving mechanism 2 includes a hydraulic system and an electric control system. The hydraulic system provides the power source for the lifting and clamping of the entire platform through an integrated sealed hydraulic station; the electric control system controls the lifting of the working platform 3 and the telescoping of the hydraulic cylinder through the system.

[0038] It should be noted that the implementation process of the hydraulic steel pile construction platform provided in this embodiment is as follows: After the first section of the steel pile is driven, use a crane to lift the entire construction platform, lower it so that the pile head of the first section of the steel pile passes through the reserved hole in the middle of the upper platform of the present invention, place the base 1 on the prefabricated I-beam tooling, and at the same time use the fixed rib plates to fix the construction platform on the catwalk of the jacket.

[0039] Connect power to the electric control system, and then start the hydraulic system to provide energy for the scissor structure. The hydraulic cylinder rod inside the scissor mechanism extends, driving the scissor arm to move, thereby raising the working platform 3 to the designed height. When the ideal working height is reached, the clamping arm hydraulic cylinder near the pile leg at the lower part of the working platform 3 extends under the control of the hydraulic system, generating a maximum clamping force of 15t on the steel pile, thereby firmly fixing the entire working platform 3 tabletop on the pile leg to ensure the construction safety of construction personnel and construction tools.

[0040] Construction personnel will, in accordance with the process of steel pile construction, first use a magnetic cutter to cut the pile head, and then grind the cut part of the steel pile. After the groove reaches the welding standard, hoist and assemble the second section of the steel pile to the groove position, and start the assembly and welding work. After welding is completed, the weld joint needs to be inspected. After the inspection is completed, control the four hydraulic cylinder clamping mechanisms 5 to release through the remote control, and then control the scissor mechanism to retract the working platform 3. After retracting to the minimum height, connect the sling and move the construction platform to the remaining pile legs to continue construction.

[0041] Obviously, the above-mentioned embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limitations on the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation manners here. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the claims of the present invention.
