Description
Technical field
The present invention relates to oil exploitation field of tool, and in particular to the drilling and completing fluids pressure cat head of three faces protection steel wire rope.
Background technology
With the development of petroleum equipment industry, oil-well rig automaticity more and more higher, the requirement to rig is also increasingly
Lightness, to meet the requirement of rig lightness, it is desirable to each matching component Highgrade integration of rig.Hydraulic catwork is on drill bit
Using also more and more frequently, shackle efficiency in the raising of high degree being capable of by hydraulic catwork, reduction makes up a joint, connects column
Time, so as to reduce time-consuming, the raising brill completion efficiency that makes a trip.Hydraulic catwork frequently with integral structure, directly by base plate
On drilling floor surface.But hydraulic catwork needs to use its active force of wire rope transfers to tong in use, and one
Denier is not in place to the inspection and maintenance of steel wire rope, then easily cause the accident broken during steel wire rope use, causes driller to be subject to
Injury.Especially for area it is small, hide the limited offshore drilling platform in space for because the steel wire rope on hydraulic catwork collapses
Security incident that is disconnected and causing happens occasionally.
The content of the invention
Drilling and completing fluids it is an object of the invention to provide three faces protection steel wire rope press cat head, to solve liquid in the prior art
Steel wire rope on pressure cat head breaks and easily causes the problem of security incident, after realizing that the steel wire rope reduced on hydraulic catwork breaks
The purpose of harm.
The present invention is achieved through the following technical solutions：
The drilling and completing fluids pressure cat head of three faces protection steel wire rope, including the support on rig floor is fixed on, it is rack-mount
Hydraulic cylinder, and the steel wire rope winding device at the top of hydraulic cylinder is connected to, housing is set outside the steel wire rope winding device and is gone out
Rope mouth, the left side of the rope outlet, right side, upside are provided with the expansion plate being connected on housing, the left side of rope outlet, right side
Expansion plate be connected on housing by rotating shaft, the expansion plate on the upside of rope outlet by gemel connection on housing；It is all flexible
Plate stretches out direction and is extended towards steel wire rope, and all expansion plates are also secured to one piece of baffle plate away from one end of housing
On；Through hole is opened up on the baffle plate.
After being broken for the steel wire rope on hydraulic catwork in the prior art, the problem of security incident is easily caused, the present invention
The drilling and completing fluids pressure cat head of three faces protection steel wire rope is proposed, the hydraulic cylinder of hydraulic catwork is fixed on rig floor by support, hydraulic pressure
Cylinder top sets steel wire rope winding device, housing and rope outlet according to existing mode, and in order to reduce potential safety hazard, the present invention is going out
The left and right sides and upside of rope mouth respectively set one piece of expansion plate, and expansion plate is connected on housing, is supported and carrying by housing.
Expansion plate uses existing stretching structure, is preferably Telescopic metal plate improving intensity.All expansion plates are towards steel
Cord is stretched out direction and is extended, i.e., protected in the steel wire rope left and right sides and upside by three pieces of expansion plates.Three pieces are stretched
Plate is each attached on one piece of baffle plate away from one end of housing, and each expansion plate is linked together by baffle plate, while passing through baffle plate
On through hole, be easy to steel wire penetrating baffle plate to carry out normally going up shackle operation.The left side of rope outlet, the expansion plate on right side pass through
Rotating shaft is connected on housing so that the expansion plate of both sides can be rotated on housing around the shaft, hence for different upper
Shackle height can be protected suitably, and the angle of expansion plate is adjusted flexibly as needed, improve applicability of the invention.
Expansion plate on the upside of rope outlet is by gemel connection on housing so that the expansion plate of upside can be with the shifting of both sides expansion plate
Move and adjust angle of inclination, it is ensured that the relative position between each expansion link keeps constant, is always positioned at three directions of steel wire rope.
During present invention work, the through hole on steel wire penetrating baffle plate, then be attached with the drilling well tong of well head, driller can pull gear
Plate makes baffle plate be moved near the region of drilling well tong, and now steel wire rope most areas are all carried out by each expansion plate elongation
The left and right sides and the obstruct of upside, the accident once steel wire rope breaks, due to the resistance of its left and right sides and the expansion plate of upside
Gear and baffle plate are spacing with through hole, and steel wire rope can all be limited to the splashing of both sides and top by largely, and under
Square region is rig floor ground, belongs to safety zone, so that injury of the reduction of high degree to the driller near rig floor, realizes drop
Steel wire rope on low hydraulic catwork break after harm purpose.
Preferably, the expansion plate is made by aluminum alloy materials.Aluminum alloy materials intensity is high, while light weight,
While ensuring the intensity of expansion plate, ensure its protective capacities, expansion plate own wt can be reduced, reduction is applied on housing
Load, while reducing flexible difficulty.
Preferably, the expansion plate is made up of N sections of sheet material, and N sections of sheet material is from the connection end of expansion plate and housing, to expansion plate
With the connection end of baffle plate, width gradually reduced with height, and every section of sheet material can be inserted in larger one block of sheet material adjacent thereto, its
Middle N is the integer more than or equal to 2.It is that expansion plate is made up of the sheet material that N sections of width is gradually reduced with height, every section of sheet material can
Retract into adjacent big sheet material, while also can easily be extracted out, that is, be so that expansion plate is mechanical retractable knot
Structure, so as to easily realize flexible function.
Preferably, the baffle surface is fixed with clamping device.Clamping device is fixed on baffle surface, for through logical
The steel wire rope in hole is clamped, so that baffle plate can be moved with the movement of steel wire rope, each expansion plate is driven with this
Elongation and contraction.The clamping device uses existing steel wire rope clamping device such as clip, buckle, anchor ear etc..
The present invention compared with prior art, has the following advantages and advantages：
The drilling and completing fluids pressure cat head of three faces protection steel wire rope of the invention, make through hole on steel wire penetrating baffle plate again with well head
Drilling well tong be attached, driller can pull the baffle plate baffle plate is moved near the region of drilling well tong, now each flexible
Plate is extended, and steel wire rope most areas are all carried out with the obstruct of the left and right sides and upside, the accident once steel wire rope breaks,
Because the stop of its left and right sides and the expansion plate of upside and baffle plate are spacing with through hole, steel wire rope is to both sides and top
Splashing can all be limited by largely, and lower zone is rig floor ground, belongs to safety zone, so that high degree
Reduce injury to the driller near rig floor, realize the steel wire rope reduced on hydraulic catwork break after harm purpose.
