Description

Technical Field

[0001] The invention relates to the technical field of offshore construction, and in particular to a control vehicle for an offshore sliding system. Background Art

[0002] At present, when moving equipment or cargo on offshore platforms and offshore engineering vessels, rollers, hand winches and manual jacks are usually used for side loading of equipment. However, when the weight of the equipment is relatively large, the above methods will result in a large investment of manpower and material resources, and the construction efficiency is low; moreover, there is a risk of damage to the local structure of the platform or the hull structure, and even due to the arrangement of the structural beams under the deck surface of the platform module, it is impossible to directly use rollers as support for transportation.

[0003] In order to solve the above technical problems, a device for side loading and transporting of marine platform equipment has emerged. The patent document with Chinese patent application number 201620360894.X and announcement date 2016.11.23 discloses a transport device for side loading of marine platform equipment. The transport device for side loading of marine platform equipment includes a supporting device and a lifting mechanism arranged at the bottom of the equipment, and a traction mechanism arranged in front of the equipment, wherein the supporting device includes: a plurality of sliding plates and a plurality of assembly slideways arranged at the bottom of the equipment; a plurality of roller vehicle groups and a plurality of roller tracks arranged at the bottom of the plurality of roller vehicle groups; the traction mechanism includes: a traction cylinder installed on the deck, an equipment connector installed on the piston rod of the traction cylinder, and a reaction seat fixed on the deck; the lifting mechanism includes: a plurality of lifting cylinders installed on the deck, and a synchronous hydraulic pump station connected to the plurality of lifting cylinders, the synchronous hydraulic pump station is respectively connected to the traction cylinder and the lifting cylinder, and can perform transport, lifting and lowering operations.

[0004] However, the traction mechanism unidirectionally arranged at one end of the assembly slideway of the equipment realizes the transportation operation by connecting the steel strands through a piston rod. If bidirectional transportation is to be achieved, traction mechanisms need to be respectively arranged at both ends of the assembly slideway, and the long-distance steel strands may hinder other offshore operations during the transportation process.
