A locking device suitable for self-elevating platform

Abstract

The invention discloses a locking device suitable for a self-elevating platform, and belongs to the field of ocean platforms. The locking device comprises a locking tooth block, a horizontal telescopic assembly, a plug pin assembly, a lifting assembly and a locking support. One end of the horizontal telescopic assembly is hinged to a pile fixing frame of the self-elevating platform, and the otherend of the horizontal telescopic assembly is hinged to the locking tooth block; and the locking tooth block is used for meshing with racks of a pile leg of the self-elevating platform. The lifting assembly is located above the locking tooth block, is hinged to the pile fixing frame, and is used for driving the locking tooth block to move along the length direction of the racks of the pile leg. Thelocking support is fixed on the pile fixing frame, and the bottom of the locking support is used for abutting against the top of the locking tooth block. The plug pin assembly is used for abutting against one side, back to the racks of the pile leg, of the locking tooth block. According o the locking device, a load of the self-elevating platform is transferred from a lifting system to the lockingdevice, and the pile leg and a platform structure are firmly locked so as to resist the load in working conditions of platform towing and storms.

Description

technical field [0001] The invention belongs to the field of ocean platforms, in particular to a locking device suitable for self-elevating platforms. Background technique [0002] A jack-up platform is a structure that provides production and living facilities for offshore drilling, oil production, transportation, observation, navigation, construction and other activities; it usually consists of platform structures, pile legs, lifting systems, locking devices and living buildings. Composition, wherein the locking device is used to firmly lock the legs and platform structure to resist the load under the platform towing and storm conditions. [0003] The existing self-elevating platform includes two locking devices, and the two locking devices are symmetrically arranged on both sides of the leg rack. Each of the locking devices includes: a locking tooth block, a mounting frame, and a on the leveling jack. One end of the horizontal jack is fixedly connected with the locking ...
