Description

A kind of clamping device on offshore oil and gas process units crane dead man wirerope

Technical field

The utility model relates to the crane technical fields of offshore oil and gas process units, relate more specifically to a kind of offshore oil and gas Clamping device on process units crane dead man wirerope.

Background technique

Offshore oil and gas process units is stood among sea like an isolated island, and material supply, makes a trip at personnel's transhipment Equal operations must be completed frequently by platform crane, in addition to be chronically at salt fog, moisture and sunlight sudden and violent for offshore platform crane In the adverse circumstances of solarization, crane rope is highly prone to electrochemical corrosion caused by saliferous moisture and other impurities, chemistry corruption Erosion and the influence of fatigue wear.To causing crane rope comdemning period short, the problems such as frequency of more change steel rope is higher.

Therefore crane rope periodic maintenance is replaced, keeps its functional, the tragedy of car crash is avoided to occur, shown It obtains particularly important.Especially crane is up to the dead line head of crane dead man wirerope in more than ten meters of A type frame in replacement, it is necessary to according to By manpower by the rope made of hemp by the dead line head pulling to A type frame for weighing hundred jin, not only labor efficiency is low, and labor intensity is high, and Poor safety performance etc..Although the dead man wirerope dead line head in replacement crane A type frame is the basic work of field device maintenance maintenance Make, but be even more that more stringent requirements are proposed to paving assistant engineer tool, challenge is proposed to special maintenance work, to ensure the steady of crane It is fixed reliable.

When replacing crane dead man wirerope, roller side is easy practical loop wheel machine dead man roller and carries out promoting dragging wirerope, And after crane " A " type frame side then utilizes the rope made of hemp to bundle wirerope, it is pulled using manpower.It will cause various problems in this way:

1, operational security is poor, and over one hundred jin of the crane dead man wirerope dead line head of weighing is pulled to tens meters of high cranes In A type frame, it is desirable that operating personnel must be in fine weather and crane high-altitude drive all one's effort, while requiring operating personnel in operation Process hand cannot have skidding to be possible to accomplish；

2, labor efficiency is low, and over one hundred jin of the crane dead man dead line head of weighing is pulled in tens meters high of crane A type frame, It generally requires that 5, platform between twenty and fifty strength is concentrated to expend the time of 4 hours to complete；

3, large labor intensity, over one hundred jin of the crane dead man dead line head of weighing fully rely on manpower and pull to tens meters high In crane A type frame, large labor intensity.

4, the confidence that labourer establishes wisdom oil field is reduced, with the arrival in wisdom oil field, carries out crane dead man steel The installation of cord dead line head fully relies on manpower, reduces the confidence that platform operations personnel establish wisdom oil field, has hit new person The confidence of traditional gas industries is added.

5, the awkward situation for causing Modern platform operation to live at the mercy of the elements installs crane dead man especially at the South Sea that There are billows three feet high even if there is no wind Dead line head has to wait for fine weather, restores to wait the equal urgent work that makes a trip in the poor environment crane gin pole wirerope of weather When industry, it is but unable to the predicament of operation.

6, to operator, more stringent requirements are proposed for quality at heart, especially the feelings fewer in number of wellhead platform operation at sea Under condition, by crane dead man dead line head fully rely on manpower pull in tens meters high of crane A type frame, need to coordinate probably it is high, The high operator of quality at heart.
