Abstract

The invention discloses a hydraulic inserted pin lifting device, and belongs to the field of marine engineering equipment. The hydraulic inserted pin lifting device comprises a pile fixing bracket, afirst ring beam, a second ring beam, a first ring beam inserted pin assembly and a second ring beam inserted bin assembly, wherein the pile fixing bracket comprises a pile fixing bracket ring beam; and the pile fixing bracket ring beam, the first ring beam and the second ring beam are coaxially arranged at intervals in sequence. The hydraulic inserted pin lifting device also comprises at least twolifting devices, wherein the at least two lifting devices are arranged at intervals around pile legs; each lifting device comprises a power toothed bar, a supporting oil cylinder, two lifting toothedbars, two lifting gears, two driving gears and two driving assemblies. The hydraulic inserted pin lifting device has the beneficial effects that a self-lifting type marine platform depends on the driving gears and the lifting gears to continuously crawl and lift on the lifting toothed bars and the power toothed bar to and fro so as to realize continuous lifting.

Description

technical field [0001] The invention relates to the field of marine engineering equipment, in particular to a hydraulic bolt lifting device. Background technique [0002] The hydraulic bolt lifting device is a commonly used lifting device for self-elevating offshore platforms. [0003] An existing hydraulic bolt lifting device mainly includes: pile legs, a moving ring beam, a fixed ring beam and a lifting cylinder. The movable ring beam and the fixed ring beam are connected by a lifting cylinder, the movable ring beam and the fixed ring beam are respectively sleeved on the pile legs, and the fixed ring beam is connected to the self-elevating offshore platform through a solid pile frame. The pile legs are provided with pin holes along the length direction, and the movable ring beam and the fixed ring beam are respectively provided with a bolt assembly inserted into the pile leg and a bolt assembly of the fixed ring beam. The lifting action of the self-elevating offshore pla...
