Abstract

The invention discloses a lifting device, and belongs to the field of lifting platforms. The lifting device comprises a pile fixing rack, plug pin mechanisms, platform lifting mechanisms and pile leg lifting mechanisms, wherein the platform lifting mechanisms comprise gears, supporting shafts, sleeves, main cylinders and sub cylinders; the gears coaxially sleeve the supporting shafts; a plurality of check blocks are arranged on the side walls of the gears in the circumferential direction at intervals; the sleeves sleeve the supporting shafts; sub cylinder mounting plates are arranged on the outer side walls of the sleeves; one ends of the sub cylinders are hinged to the sub cylinder mounting plates; pushing blocks are further hinged to the outer side walls of the sleeves; the other ends of the sub cylinders are hinged to the pushing blocks; one ends of the main cylinders are hinged to the pile fixing rack; and the other ends of the main cylinders are hinged to the outer side walls of the sleeves. According to the lifting device, the sub cylinders can be controlled to extend and retract, the pushing blocks are appressed to the check blocks, the main cylinders are controlled to extend and retract, the gears are pushed to rotate, a platform is lifted, after the platform moves for a certain distance, plug pin cylinders are controlled to extend, plug pins stretch into plug pin holes, and the platform is supported.

Description

technical field [0001] The invention relates to the field of lifting platforms, in particular to a lifting device. Background technique [0002] Lifting platform is a structure that provides production and living facilities for drilling, oil extraction, container transportation, observation, navigation, construction and other activities at sea, and is the basic equipment for developing offshore oil. The lifting platform is usually composed of a platform body, a pile leg, a pile fixing frame, and a lifting device. The lifting device is set on the fixing pile frame, and the fixing pile frame is connected with the platform body. By controlling the lifting device to move along the pile legs, the platform body can be realized. movement. As a key part of the lifting platform, the lifting device is highly valued in the design, manufacture and use of the platform, and its performance directly affects the safety performance, performance and economy of the platform. [0003] There a...
