Description

Technical Field

[0001] The utility model relates to a construction device for ocean engineering, in particular to a large-size prefabricated single-piece lifting device for oil and gas modules. Background Art

[0002] In the construction process of oil and gas modules on an offshore platform, the commonly used method is layer-by-layer construction. During construction, single pieces are prefabricated first, and then various equipment for the oil and gas modules is installed. After installation, the prefabricated single pieces of each layer are assembled and installed. During the assembly and installation process, the combined hoisting method is usually adopted. However, as the size and weight of the large-size prefabricated single pieces continue to increase, the combined hoisting method is no longer suitable for the installation of large-size prefabricated single pieces. Moreover, the combined hoisting method is prone to deformation of the prefabricated single pieces during hoisting, affecting the installation accuracy. In addition, the combined hoisting is somewhat dangerous and is prone to tipping over during hoisting, easily causing dangerous accidents. Summary of the Invention

[0021] The hydraulic cylinder, the bearing hydraulic cylinder 1-2 and the clamping hydraulic cylinder 1-4 are connected to a computer through data lines.

[0022] The working principle of this system is as follows:

[0023] During the construction of the large-sized prefabricated single piece 2 in the oil and gas module, multiple jacking devices 1 are placed at the bottom of the large-sized prefabricated single piece 2. When it is necessary to construct the second layer after the completion of the first layer of the prefabricated single piece 2, the first layer of the prefabricated single piece 2 needs to be lifted. The jacking height of the load-bearing hydraulic cylinder 1-2, the first descent distance, and the second descent distance are set in the computer. The computer controls the telescopic rod of the clamping hydraulic cylinder 1-4 to extend, pushing the insertion plate 1-7 into the insertion plate through-hole 1-6-3 of the support cushion pier 1-6. The telescopic rod of the clamping hydraulic cylinder 1-4 stops extending. Then the computer controls the telescopic rod of the load-bearing hydraulic cylinder 1-2 to extend, jacking up the load-bearing plate 1-3, the clamping hydraulic cylinder 1-4, and the support cushion pier 1-6 to the set jacking height. The telescopic rod of the load-bearing hydraulic cylinder 1-2 stops extending. On-site, a forklift is used to fork and install through the forklift jacking hole 1-6-2 on the support cushion pier 1-6 onto the positioning block 1-1-1 on the load-bearing block 1-1. The load-bearing head of the forklift withdraws from the forklift jacking hole. The load-bearing hydraulic cylinder 1-2 retracts the first descent distance, placing the load-bearing plate 1-3, the clamping hydraulic cylinder 1-4, and the support cushion pier 1-6 on the newly installed support cushion pier 1-6. The clamping hydraulic cylinder 1-4 retracts, driving the left and right insertion plates 1-7 to disengage from the insertion plate through-hole 1-6-3 on the support cushion pier 1-6. The load-bearing hydraulic cylinder 1-2 retracts the second descent distance. Then the telescopic rod of the clamping hydraulic cylinder 1-4 extends again, pushing the insertion plate 1-7 into the insertion plate through-hole 1-6-3 of the support cushion pier 1-6. The computer controls the telescopic rod of the load-bearing hydraulic cylinder 1-2 to extend, jacking up the load-bearing plate 1-3, the clamping hydraulic cylinder 1-4, and the support cushion pier 1-6 to the set jacking height. On-site, the forklift is used again to fork and install through the forklift jacking hole 1-6-2 on the support cushion pier 1-6 onto the positioning block 1-1-1 on the load-bearing block 1-1. This is repeated until the first layer of the prefabricated single piece 2 is jacked up to the height of the load-bearing support column 3, and the load-bearing support column 3 is supported at the bottom of the large-sized prefabricated single piece 2.
