Embodiment
[0038] An embodiment of the present invention provides a locking mechanism for a rack and pinion lifting system, which is suitable for locking the leg rack a of the rack and pinion lifting system, such as figure 1 As shown, the locking mechanism includes a mounting frame 1 fixed on the platform, a first locking component 2 and a second locking component 12, and the first locking component 2 and the second locking component 12 are symmetrically arranged on the mounting frame 1 Inside.
[0039] The structure of the second locking component 12 is the same as that of the first locking component 2 . For ease of description, in this embodiment, the components or structures represented by "first" belong to the first locking assembly 2, and the components or structures represented by "second" belong to the second locking assembly, which are only used for distinction.
[0040] figure 2 It is a schematic diagram of the rear view structure of the locking mechanism. image 3 It is a s...

The invention discloses a locking mechanism of a gear rack lifting system, and belongs to the field of ocean platform fittings. The locking mechanism also comprises a first locking assembly and a second locking assembly, wherein the first locking assembly and the second locking assembly are respectively located in a mounting frame, and are symmetrically arranged on two sides of a spud leg rack; the first locking assembly comprises a rack frame, a guide rail assembly, a locking rack, a horizontal locking sloping block, a vertical locking sloping block, a locking sloping block oil cylinder, horizontal locking rack oil cylinders and a vertical locking rack oil cylinder; the rack frame comprises an upper connecting plate, a lower connecting plate and a side plate; the upper connecting plate and the lower connecting plate are arranged in a relatively parallel manner, and are respectively and vertically fixed on the side plate; the guide rail assembly is fixed to the mounting frame; and the side plate is mounted on the guide rail assembly in the length direction of the spud leg rack in a sliding manner. According to the locking mechanism disclosed by the embodiment of the invention, only an ordinary locking sloping block oil cylinder is needed to realize the function of locking, and the cost of the ordinary oil cylinder is greatly lower than that of a jack, so that the cost of the locking structure is greatly reduced.
Description
technical field [0001] The invention relates to the field of offshore platform accessories, in particular to a locking mechanism of a rack and pinion lifting system. Background technique [0002] The current offshore platform lifting system, especially the rack and pinion lifting system with a large operating support load such as a drilling platform, is usually equipped with a separate locking device. The locking device can lock the legs and the platform, and is used to bear the load of the platform in offshore operation, storm conditions and towing conditions. [0003] An existing rack and pinion lifting system is provided with two locking devices. The two locking devices are symmetrically arranged on both sides of the leg rack of the self-elevating offshore platform. Each locking device includes a locking inclined block, two A locking tooth block, a horizontal jack fixed on the mounting frame, a connecting plate, and a telescopic device, the upper and lower ends of the lo...
