By virtue of the hoisting device of the electric-measuring crown pulley, the long-standing potential risk can be solved, the production efficiency can be improved, the production time can be saved, and the labor intensity can be reduced.
Description
Technical field
The utility model relates to drilling well lifting device equipment technical field, is specifically related to a kind of electrical measurement crown sheave hanging apparatus.
Background technology
At present, the operation of marine drilling platform extension electrical measurement crown sheave must be carried out operation by the professional staff who takes appointment with certificate.The defect of its method of work and existence is as follows: employment is many, and job schedule is slow.Before starting working, will at first hang cage, and check cage, pneumatic hoist is safe and reliable can mannedly construct.Use two pneumatic hoists, one is lifted by crane another and does safety precaution use (two people operate simultaneously pneumatic hoist and are equipped with interphone).Preparation tool is various, and horse-shoe collar is arranged, spanner, steel rope, hauling rope, pin, hand vice waits instrument, will be all tail rope after instrument is ready to, and prevents in lifting and installs, in decentralization process, fall and cause the generation of accident, must before construction, be checked, confirm that it is intact, can place in operation.Go up simultaneously two people's wear safety belts and be equipped with interphone and just start lifting, in the lifting process, hinder manyly, inevitable scratching, strengthened danger coefficient.Sitting cage installation electrical measurement crown sheave is subjected to weather effect large.When rainy day and snow day carry out operation, must take that failure-free is anti-skidding, winter protection and antifreezing measures.All water, ice, frost, snow all should be removed in time.Strong wind, snow day, the rainy day, the weather such as dense fog exist higher risk, and the length that expends time in, and generally need one hour more than, and inclement weather is even longer or cause can't normal operation.It is that tourist bus can not raise and decentralize that stiff drilling tool in electrical measurement crown sheave process is installed, and in horizontal drainhole, causes sticky bit freezing or other down-hole accidents inhaled because rest time is long, has serious consequences to production.Because of extension electrical measurement crown sheave below derrick crown wheel, high and the pneumatic hoist rope in position, liquid gas tong, and the existence of other sling cables causes narrow space and limitation of activity and pneumatic hoist rope have been at the end, even safety puts in place, rise and put personnel that cage is gone up and still can refuse this work (due to the feared state of mind).In installation process lest fear psychology etc. former thereby can not the once mounting success and hand tool or pin etc. have drop may, under cage, be the operating personal (manned pneumatic hoist must not from the people) of two pneumatic hoists, increased potential safety hazard.In decentralization process, still exist above-mentioned danger.While after electrical measurement, tearing the electrical measurement crown sheave open, still will repeat said process, will first pulley be hung on cage after arriving the crown sheave position, recurrence hanging cage, if the bad and accident such as cause that personnel fall is very easily drawn cage in contact not in time up and down.The electrical measurement of water horizontal well will twice just can complete at least, has therefore strengthened again potential safety hazard.
Summary of the invention
The purpose of this utility model is exactly the defect existed for prior art, and a kind of electrical measurement crown sheave hanging apparatus is provided.
Its technical scheme is: electrical measurement crown sheave hanging apparatus comprises portable clamping piece, hold-down arm, suspension ring, fixed pulley, movable pulley, stay cord, bolt and bearing pin.Described portable clamping piece is the U-steel structure of open end towards a side, its end is interspersed with bolt, one end of described hold-down arm is fixedly connected on the downside of portable clamping piece, the other end of hold-down arm is connected with semi-round suspension ring by bearing pin, the hook of fixed pulley is articulated on suspension ring, one end of described stay cord becomes the live line of circular ring to buckle by bolt clamp mounting ring, and the other end of stay cord passes the wheel shaft of movable pulley and the wheel shaft of fixed pulley in turn, and the hook of movable pulley is downward.
Wherein, described hold-down arm is metal tube.Described stay cord is steel rope, coir rope or nylon rope.
The utility model is reasonable in design, simple in structure, safe and convenient to use.It has the following advantages compared with prior art: 1, whole working process need only two people.Forble board one people, rig floor pneumatic hoist one people, in the lifting process, crown sheave need only be risen and rises to forble board, derrick monkey's operation hangs over the electrical measurement crown sheave on the movable pulley of system, pneumatic hoist can be pulled down, then by derrick monkey's operation, the electrical measurement crown sheave is risen and rises to suitable height and the live line end is fixed and can be completed whole work.2, serviceable tool only needs the open-end spanner of 17 to get final product (forble board operative employee use).3, when manual pneumatic hoist is installed, only need a people and deducted the use of instrument and complete whole working process.
The accompanying drawing explanation
Fig. 1 is the structural representation of a kind of embodiment of the utility model.
The specific embodiment
With reference to Fig. 1, a kind of electrical measurement crown sheave hanging apparatus, comprise portable clamping piece 1, hold-down arm 2, suspension ring 4, fixed pulley 5, movable pulley 6, stay cord 7, bolt 10 and bearing pin 3.Described portable clamping piece 1 is the U-steel structure of open end towards a side, its end is interspersed with bolt 10, one end of described hold-down arm 2 is fixedly connected on the downside of portable clamping piece 1, the other end of hold-down arm 2 is connected with semi-round suspension ring 4 by bearing pin 3, the hook of fixed pulley 5 is articulated on suspension ring 4, one end of described stay cord 7 becomes the live line of circular ring to buckle 9 by bolt clamp 8 mounting rings, the other end of stay cord 7 passes the wheel shaft of movable pulley 5 and the wheel shaft of fixed pulley 6 in turn, and the hook of movable pulley 6 is downward.Wherein, described hold-down arm 2 is metal tube.Described stay cord 7 is steel rope, coir rope or nylon rope.
During use, portable clamping piece 1 is articulated on the derrick crossbeam, and fixing by bolt 10, and the live line of the circular ring of stay cord 7 is buckled 9 and is enclosed within on the derrick crossbeam, on the hook of movable pulley 6, articulates the electrical measurement pulley and gets final product.
Whole working process need only two people.Forble board one people, rig floor pneumatic hoist one people, in the lifting process, crown sheave need only be risen and rises to forble board, derrick monkey's operation hangs over the electrical measurement crown sheave on the movable pulley 6 of this device, pneumatic hoist can be pulled down, then by derrick monkey's operation, the electrical measurement crown sheave is risen and rises to suitable height and the other end of stay cord 7 is fixed and can be completed whole work.When manual pneumatic hoist is installed, only need a people and deducted the use of instrument and complete whole working process.The utility model has solved the potential safety hazard existed for a long time and has improved production efficiency, saves production time, has reduced labour intensity.
