Problems solved by technology
The usual locking mechanism is to configure locking racks on both sides of the rack, and use a jack to press the locking rack against the rack on the leg of the offshore platform, so that the two mesh, so as to achieve the purpose of locking the rack , but due to the heavy load on the offshore platform, the hydraulic cylinder usually needs to generate hundreds of tons or even thousands of tons of pressure to achieve the locking of the rack, and such a hydraulic cylinder is extremely expensive

Embodiment Construction
[0026] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0027] figure 1 is a structural diagram of a locking mechanism provided by an embodiment of the present invention, such as figure 1 As shown, the locking mechanism is suitable for locking the rack 1a on the leg. The locking mechanism includes a mounting bracket 110 and a rack and pinion locking unit. The rack and pinion locking unit includes a rotating shaft 120 and a locking pinion 122. , the locking gear 121, the oil cylinder assembly and the locking rack 131, the rotating shaft 120 is rotatably arranged in the installation frame 110, the locking pinion 122 is coaxially fixed on the rotating shaft 120, and the locking gear 121 is coaxially fixed on the rotating shaft 120, the indexing circle diameter of the locking gear 121 is great...

The invention discloses a locking mechanism, which belongs to the field of ocean platforms, and comprises an installation rack, a rotary shaft, a locking pinion, a locking gear wheel, an oil cylinder assembly and a locking rack. The rotary shaft is arranged in the installation rack; the locking pinion and the locking gear wheel are fixed to the rotary shaft; the locking pinion is meshed with a rack on a pile leg; when the rack needs to be locked, the movement of the locking rack is controlled through the oil cylinder assembly, so that the locking rack is meshed with the locking gear wheel; the locking rack is compressed on the locking gear wheel, so that the rack on the pile leg is locked; and when the rack on the pile leg is locked, the sum of moments of the locking gear wheel and the locking pinion on the rotary shaft is zero, but the pitch diameter of the locking gear wheel is larger than the pitch diameter of the locking pinion, so that the force produced by the locking rack on the locking gear wheel is smaller than the force produced by the rack on the locking pinion, and thus the oil cylinder assembly can compress the locking rack on the locking gear wheel to lock the rack through a smaller force.
Description
technical field [0001] The invention relates to the field of offshore platforms, in particular to a locking mechanism. Background technique [0002] An offshore platform is a structure that provides production and living facilities for activities such as drilling, oil extraction, consolidation, observation, navigation, and construction at sea. [0003] The rack-and-pinion offshore platform is widely used due to its fast lifting speed. The lifting gear on the offshore platform is meshed with the rack on the leg to control the rotation of the lifting gear, so that the lifting of the offshore platform can be realized. There is also a very important mechanism in the rack-and-pinion offshore platform - a locking mechanism. When the offshore platform stops lifting, the rack needs to be locked so that the offshore platform can be supported at a certain height. The usual locking mechanism is to configure locking racks on both sides of the rack, and use a jack to press the locking r...
