Problems solved by technology

[0013] The volume of the rope unwinding and rewinding device is fixed. When it is necessary to wind the rope in a certain area on the drilling platform, if the area is small, the existing large-volume rope unwinding and rewinding device cannot be installed; Rope uncoilers and rewinders can be installed in areas of different sizes on the drilling platform, and it is necessary to use rope rewinders of various sizes, which increases the cost; moreover, when transporting the rope unwinder and rewinder to the drilling platform During the process, the larger rope unwinding and rewinding device will also occupy a larger transportation space

Abstract

The invention relates to the technical field of rope winding, in particular to a rope unwinding and rewinding device for a drilling platform, which includes a cross mechanism, a support frame, a knob, a screw and a screw nut; two support frames are arranged side by side; There are two groups. The cross mechanism includes inner end plate, cross plate, outer end plate and connecting cylinder. The inner end plate, outer end plate and connecting cylinder are all annular structures, and the inner end plate, outer end plate and connecting cylinder are the same The shafts are arranged side by side, the connecting cylinder is connected with the outer end plate, the connecting cylinder is rotatably set on the support frame, the cross plate or the outer end plate is provided with a rope end connection structure, and the two ends of the cross plate are respectively connected with the inner end plate in the cross mechanism of the same group. Connected with the outer end plate, multiple cross plates are evenly arranged around the central axis of the inner end plate, and the multiple cross plates in each set of cross mechanisms are slidably connected to the inner end plate and the multiple cross plates in another set of cross mechanisms. The present invention can flexibly adjust the volume so as to be suitable for setting areas of different sizes.

Description

technical field [0001] The invention relates to the technical field of rope winding, in particular to a rope unwinding and rewinding device for a drilling platform. Background technique [0002] On offshore oil drilling platforms, various slings and cables are used, such as steel wire ropes, and the winding of steel wire ropes requires the use of rope unwinders and rewinders. In this case, the rope unwinding and rewinding device is a winch under the common knowledge, and can also be called a rope winder, which is used for winding or unwinding slings and cables. The rope unwinding and rewinding device (winch) includes at least the following three types of usage scenarios: [0003] 1. Application in emergency drills and rescue and escape [0004] 1.1. The lifeboat is generally put into the sea water through the rope, and the rope unwinding and rewinding device is set on the drilling platform, which can unwind the rope and put the lifeboat down to facilitate the escape of per...
