Embodiment Construction
[0021] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0022] A kind of wire rope assisted self-locking underwater equipment remote salvage device of the present invention, such as figure 1 As shown, it includes an inner casing 12 arranged as a stepped gyratory structure, the upper end of the inner wall of the inner casing 12 is threadedly connected with a wire rope fixing ring 2, and a steel wire rope 1 is installed in the wire rope fixing ring 2, and the lower end of the outer wall of the inner casing 12 passes through The outer casing 10 is threadedly connected, and the inner side of the outer casing 10 is a stepped rotary surface. One end of the locking drive sleeve 9 is set between the inner casing 12 and the outer casing 10, and the other end of the locking drive sleeve 9 is sleeved on the wire rope. Between the fixed ring 2 and the outer shell 10, the inner shell 12 is provided with a grav...

The invention discloses a wire-rope-assisted self-locking remote salvage apparatus for underwater equipment. The wire-rope-assisted self-locking remote salvage apparatus is composed of a wire rope, awire rope fixing ring, a fastener, a plug, a compression spring, a hanging pin, a gravity ring, a gravity ring supporting block, a locking actuating sleeve, an outer shell, a locking block, an inner shell and an anchor. The wire-rope-assisted self-locking remote salvage apparatus provided by the invention can realize automatic alignment with and locking of the anchor fixed on the underwater equipment only through the gravity of the apparatus and a self-locking mechanism with the aid of ROV, so a damaged or broken guiding wire rope on a guide post can be rapidly replaced in deep water, the guiding effect of the guiding wire rope is restored, abnormal wire ropes can be replaced without recovery, re-lowering and re-installation of the underwater equipment under a deepwater condition, and theunderwater equipment can be rapidly recovered without a special tool; and thus, the working efficiency of the underwater equipment is effectively improved, and operation cost and operation risks are reduced.
Description
technical field [0001] The invention belongs to the technical field of oil and gas drilling equipment, and relates to a remote fishing device for a self-locking underwater equipment assisted by a wire rope. Background technique [0002] In the underwater wellhead device system with guide rope installation, the guidance of the drilling equipment when operating between the operation platform and the underwater wellhead is usually realized by the guide rope. The guide column is then fixed on the wellhead. During the drilling and completion operations, one or more guiding ropes often break or become damaged. If the damaged part of the guiding rope is beyond the scope of the diver’s work, the diver cannot dive down to complete the quick replacement of the guiding rope. At this time, it is necessary to Use special tools to retrieve the guiding device containing the guiding column back to the operation platform, replace the new wire rope, and re-lower and install the guiding devic...
