Loading device for entirely applying simulative load to ocean work-over rig

Abstract

The invention discloses a loading device for entirely applying a simulative load to an ocean work-over rig. The loading device comprises a front transverse beam and a back transverse beam which are symmetrically arranged at the both sides of an X shaft. The end parts of the front transverse beam and the back transverse beam are fixedly connected with a supporting leg of a base under the work-over rig; a left vertical beam and a right vertical beam are symmetrically arranged at the both sides of a Y shaft between the front transverse beam and the back transverse beam; loading boards are arranged on the end parts of the front transverse beam and the back transverse beam; connection through holes are arranged on the loading boards; and the front transverse beam, the back transverse beam, the left vertical beam and the right vertical beam are respectively provided with leveling and supporting hydraulic cylinders. The loading device disclosed by the invention can be used for entirely applying the simulative load to the ocean work-over rig when the ocean work-over rig carries out security detection and estimation test work in a condition of a field environment of an offshore platform, so that the comprehensiveness and the effectiveness of the test work can be ensured.

Description

technical field [0001] The invention relates to a loading device, in particular to a loading device for applying a simulated load to a marine workover rig under the environmental conditions of an offshore platform. Background technique [0002] As the design service life of offshore drilling and workover equipment is approaching, it is an indispensable task to conduct comprehensive and effective safety testing and evaluation of the structural bearing capacity of existing offshore drilling and workover equipment equipped on offshore oil production platforms . Through the implementation of the corresponding necessary inspection and test items for the drilling and workover equipment in service, the safe working performance of the drilling and workover equipment can be confirmed, and the unsafe state of the drilling and workover equipment can be reduced, thereby reducing the occurrence of safety accidents and effectively Improve the economy of the enterprise and the safety of p...

Problems solved by technology

Using this method to carry out the load loading work of the load test has great problems in terms of economy, safety, efficiency, etc., and it is difficult to bear for all aspects of implementation.

[0006] 2) When carrying out the test and evaluation of bearing capacity, the method of partial loading is adopted, that is, the test load is only applied to the main key component derrick. The method is to use simple tooling beams to connect with the turntable bearing beams, and the loading pins are designed on the tooling. After being assembled with the lifting ring suspended from the hook, the loading of the derrick part can be realized, which can be effectively implemented on the offshore platform site, but the disadvantage is that the loading of the main structure of the drilling and repairing machine is not comprehensive, and the test content is not comprehensive.

The structure and function of the existing loading tooling are relatively simple, and the loading range is small, which can only be used to apply test loads to the main structure of the derrick assembly of the drilling and workover rig, while the structure of the upper base assembly and the lower base assembly cannot realize the simulated load. load request

Similar devices do not have more auxiliary technical functions, and the functions are relatively single

The existing tooling structure can realize the test loading function on the offshore site, and can also realize the test loading function on the land site, but it has a small loading range for all structures that need to be tested on the drilling and repairing machine, which makes the structural bearing capacity test work effective and comprehensive. sex decline

[0009] To sum up, the loading effect of existing technical means and tooling is not ideal

Moreover, when the existing tooling is installed and connected at sea, because it interferes with the turntable structure, the turntable needs to be removed during the loading process to provide an effective and reasonable installation and connection space for tooling loading, and the working procedures are relatively cumbersome.
