Embodiment 1

[0039] An embodiment of the present invention provides a type test method for a lifting device, which is suitable for a hydraulic bolt-type lifting device for an offshore platform. The lifting device includes an upper ring beam, an upper bolt arranged on the upper ring beam, a lower ring beam, and a The upper and lower bolts, and the upper and lower ends are respectively connected to the lifting cylinders of the upper ring beam and the lower ring beam. see figure 1 , the method includes:

[0040] Step 101: Insert both the upper pin and the lower pin into the pin holes on the legs.

[0041] In an implementation manner of this embodiment, step 101 may include:

[0042] Both the upper and lower pins are inserted into the pin holes on the pile legs by a pin oil cylinder.

[0043] In another implementation manner of this embodiment, step 101 may include:

[0044] Manually insert both the upper pin and the lower pin into the pin holes on the legs.

[0045] Step 102 : providing ...

Embodiment 2

[0069] The embodiment of the present invention provides a system for realizing the type test method of the lifting device as provided in the first embodiment, see figure 2 , the system includes a lifting device 1 , legs 2 , a hydraulic pump station 3 , and an electrical control cabinet 4 .

[0070] In this embodiment, the lifting device 1 includes an upper ring beam 11, an upper bolt 12 arranged on the upper ring beam 11, a lower ring beam 13, a lower bolt 14 arranged on the lower ring beam 13, and upper and lower ends respectively connected to the upper Lift cylinder 15 of ring beam 11 and lower ring beam 13. The upper bolt 12 and the lower bolt 14 are respectively inserted into the bolt holes of the legs 2 .

[0071] The hydraulic pump station 3 is in communication with the lifting cylinder 15 , and the electrical control cabinet 4 is electrically connected with the hydraulic pump station 3 .

[0072] Optionally, the pitch of the pin holes of the legs 2 is greater than th...

Abstract

The invention, which belongs to the field of the marine technology, discloses a lifting device type testing method and a realization system thereof. The method comprises: an upper latch and a lower latch are inserted into latch holes of a pile leg; hydraulic oil is provided for a lifting cylinder, and the lifting cylinder is controlled to make extension motion until the oil pressure of the hydraulic oil reaches a maximum load value of the lifting cylinder; hydraulic oil is provided for the lifting cylinder, and the lifting cylinder is controlled to make contraction motion until the oil pressure of the hydraulic oil reaches the maximum load value of the lifting cylinder; and whether the upper latch, the lower latch, an upper ring beam, and a lower ring beam are damaged is checked. According to the invention, the upper latch and the lower latch are limited by the latch holes, so that the lifting cylinder can reach a set pressure. Therefore, simulation of the extra large load on the actual work condition can be realized, thereby completing the type testing of the lifting device.

Description

technical field [0001] The invention relates to the technical field of marine engineering, in particular to a type test method of a lifting device and a realization system thereof. Background technique [0002] The self-elevating offshore platform mainly includes pile legs, lifting device and platform main body. The lifting device is the key core equipment of the jack-up offshore platform, and the safety of the lifting device determines the overall safety of the jack-up offshore platform. In history, there have been many incidents in which the self-elevating offshore platform collapsed due to insufficient safety margin of the lifting device, resulting in serious accidents. [0003] In order to ensure that the safety of the lifting device meets the design requirements, it is necessary to carry out a type test (a test to verify whether the product can meet all the requirements of the technical specification) during the manufacturing process of the lifting device. The type te...
