Description
Technical field
The present invention relates to petroleum drilling completion tool field, and in particular to the hydraulic catwork for preventing guy wire from hurting sb.'s feelings.
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 directly passes through bottom plate frequently with integral structure
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 causes the accident broken during steel wire rope use, cause driller by
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
It is an object of the invention to provide the hydraulic catwork for preventing guy wire from hurting sb.'s feelings, to solve on hydraulic catwork in the prior art
Steel wire rope break the problem of easily causing security incident, realize the steel wire rope on reduction hydraulic catwork break after harm mesh
's.
The present invention is achieved through the following technical solutions：
The hydraulic catwork that guy wire is hurted sb.'s feelings, including the hydraulic catwork with steel wire rope, rope outlet are prevented, in addition to is arranged on liquid
The expansion plate of the rope outlet left and right sides of cat head is pressed, the expansion plate of both sides stretches out direction towards steel wire rope and extended, and two
The one end of the expansion plate of side away from rope outlet is provided with baffle plate；The baffle plate is fixed between the expansion plate of both sides, and the gear
It is provided with plate and allows the through hole of steel wire penetrating, the steel wire penetrating through hole, and the part of steel wire penetrating through hole to be fixed on
On through-hole wall.
After being broken for the steel wire rope on hydraulic catwork in the prior art, the problem of easily causing security incident, the present invention
Propose to be provided with rope outlet on a kind of hydraulic catwork for preventing that guy wire from hurting sb.'s feelings, hydraulic catwork, steel wire rope stretches out from rope outlet.Go out
The rope mouth left and right sides is respectively provided with expansion plate.Expansion plate use existing stretching structure, preferably for stainless steel expansion plate with
Improve intensity.Two pieces of expansion plates stretch out direction towards steel wire rope and extended, i.e., by two pieces of expansion plates in steel wire rope or so
Both sides are protected.One end away from rope outlet of two pieces of expansion plates connects one piece of baffle plate, baffle plate be fixed on both sides expansion plate it
Between, to reduce the space shared by baffle plate, it is to avoid baffle plate takes excessive space on the nervous rig floor in space.Will by baffle plate
Two pieces of expansion plates link together, while by the through hole on baffle plate, being easy to steel wire penetrating baffle plate to carry out normally upper shackle
Operation.The part of steel wire penetrating through hole is fixed on through-hole wall so that during steel wire rope movement elongation, pass through the flexible of both sides
Plate makes baffle plate also to move therewith, and expansion plate is to elongate or shorten in baffle plate moving process, from without influenceing hydraulic pressure
The normal of steel wire rope is used on cat head.During present invention work, the through hole on steel wire penetrating baffle plate, then the drilling well tong with well head
It is attached, the free end of steel wire rope is located near drilling well tong, and now baffle plate is also taken near drilling well tong therewith,
Expansion plate is extended therewith, and the barrier of the left and right sides, the accident once steel wire rope breaks, due to its left and right two are carried out to steel wire rope
The limitation being fixedly connected of through hole in the stop of the expansion plate of side and baffle plate, the splashing of steel wire rope can be by largely
Limitation so that injury of the reduction of high degree to the driller near rig floor, realize that the steel wire rope on reduction hydraulic catwork collapses
The purpose for the harm having no progeny.
It is preferred that, the expansion plate is arranged on the hydraulic catwork body of the rope outlet left and right sides by rotating shaft.It is to stretch
Contracting plate can be rotated on hydraulic catwork around the shaft, can suitably be protected hence for different upper shackle height
Shield, is adjusted flexibly the angle of expansion plate as needed, improves the applicability of the present invention.
It is preferred that, the expansion plate is made up of N sections of sheet materials, and N sections of sheet materials are from the connection end of expansion plate and hydraulic catwork, to stretching
The connection end of contracting plate and baffle plate, width is gradually reduced with height, and every section of sheet material can insert larger one block of sheet material adjacent thereto
In, wherein N is the integer more than or equal to 2.It is that sheet material of the expansion plate by N sections of width with highly gradually reducing is constituted, every section of plate
Material can be retracted into adjacent bigger one section sheet material so that expansion plate is the structure of mechanical retractable bar, so as to realize
Flexible function.
It is preferred that, two pieces of expansion plates are parallel to each other and perpendicular to baffle plate.So that two pieces of composition sides between expansion plate and baffle plate
The region of shape, is easy to steel wire rope freely to walk wherein, it is ensured that to the protection iris action of steel wire rope.
It is preferred that, the part of the steel wire penetrating through hole is bonded or is welded on through-hole wall.By being bonded or welding
Ensure the secure and reliable connection between steel wire rope and baffle plate, it is ensured that baffle plate can be moved with moving for steel wire rope, from
And ensure the protective action to steel wire rope.
The present invention compared with prior art, has the following advantages and advantages：
The present invention prevents the through hole on the hydraulic catwork that guy wire is hurted sb.'s feelings, steel wire penetrating baffle plate, then big with the drilling well of well head
Pincers are attached, and the part of steel wire penetrating through hole is fixed on through-hole wall so that during steel wire rope movement elongation, pass through both sides
Expansion plate baffle plate is also moved therewith, expansion plate is to elongate or shorten in baffle plate moving process, from without shadow
The normal of steel wire rope on hydraulic catwork is rung to use.Baffle plate is taken near drilling well tong with the free end of steel wire rope when using,
Expansion plate is extended therewith, and the barrier of the left and right sides, the accident once steel wire rope breaks, due to its left and right two are carried out to steel wire rope
The limitation being fixedly connected of through hole in the stop of the expansion plate of side and baffle plate, the splashing of steel wire rope can be by largely
Limitation so that injury of the reduction of high degree to the driller near rig floor, realize that the steel wire rope on reduction hydraulic catwork collapses
The purpose for the harm having no progeny.
