Description
Technical field
The present invention relates to oil field, in particular to horizontal well underground work to salvage frock.
Background technology
Some can be usually fallen into during oil well operation, in oil well influences the junk of operations and oil exploitation, and usually one
A little steel wire rope, cable, steel wire for logging etc. are elongated and object that body is soft, and these junks need pull out out of oil well in time, in order to avoid oil well
Block or damage equipment.Though the present rope instrument that drags for can pull rope form junk inside oil well out, efficiency is not only salvaged
It is low, and salvaging is not thorough enough, many things that drop tiny, that length is shorter are not easy to be salvaged, and cause the salvaging cycle also to extend.
The content of the invention
It is an object of the invention to provide horizontal well underground work to salvage frock, solves the conventional rope instrument that drags for and salvages effect
Rate is low, salvages halfway problem.
The purpose of the present invention is achieved through the following technical solutions：
Frock is salvaged in horizontal well underground work, is included the support column of inner hollow, is provided with the side wall of the support column
Multiple rectangular openings, the bottom of support column are provided with multiple spacing holes being connected with each other with rectangular opening, consolidated in the hollow cavity of support column
Surely there is the support bar of taper, multiple claws are connected with the side wall upper hinge of the support bar；Also include being fixed on support bar top
The electromagnet at end, electromagnet are connected by wire with external power source, and are provided with and electricity on side of the claw close to support bar
The magnet that magnet is engaged.During present invention work, rectangular opening forms L-shaped activity interval of the claw on support bar with spacing hole,
Support column is slowly put into oil well, while startup power supply so that electromagnet interacts with the magnet on claw, i.e. electromagnetism
Iron produces the upper end for attracting to cause claw to magnet and inwardly bounced back around pin joint, and the other end of claw around pin joint to extending out
So that the inner space increase for the column grasping part that multiple claws are formed, that is, ensure that claw can be whole to oil well
Internal debris, crushed stone, steel wire rope, cable rope etc. is cleared up；When the bottom of claw is placed in shaft bottom, electricity is passed through
Electric current in magnet changes so that attraction state of the electromagnet to magnet is changed into repulsion state, and the upper end of claw starts away from electricity
Magnet, and its other end is then close at mast axis place to supporting, and then cause debris in oil well etc. to enter multiple claws
The grasping part of formation, when claw inwall and spacing hole ends contact when, claw stop continue to move to, prevent multiple claws
Each other excessively movement and cause to be damaged.
Latch is fixed with the inner wall at end of the claw.Further to strengthen salvaging effect of the claw to debris, in card
Latch is installed on pawl, prevents debris from being dropped in uphill process is salvaged.
Multiple claws are in a ring and array distribution is on support bar.Multiple claw annular arrays are hinged on support bar
On so that multiple claws form a coniform grasping part, to ensure that claw is cleared up the debris in oil well completely.
Also include connector, the connector is fixed on the top of support column and coordinated with the lowering or hoisting gear of outside.Connection
Head is used to be connected with the lowering or hoisting gear of outside, and the lowering or hoisting gear can be steel cable or draw bar, passes through steel cable or draw bar
Lifting will salvage the related debris of structure and remove together in oil well.
The present invention compared with prior art, has the following advantages and advantages：
1st, support column is slowly put into oil well by the present invention, while startup power supply so that electromagnet and the magnetic on claw
Body phase interaction, i.e. electromagnet produce the upper end for attracting to cause claw to magnet and inwardly bounced back around pin joint, and claw is another
End expands outwardly around pin joint so that the inner space increase for the column grasping part that multiple claws are formed, that is, ensures claw
The debris of the whole inside of oil well, crushed stone, steel wire rope, cable rope etc. can be cleared up；
2nd, the present invention is provided with latch on claw, prevents debris further to strengthen salvaging effect of the claw to debris
Dropped in uphill process is salvaged；
3rd, the multiple claw annular arrays of the present invention are hinged on support bar so that multiple claws form a coniform folder
Space is held, to ensure that claw is cleared up the debris in oil well completely.

Embodiment
For the object, technical solutions and advantages of the present invention are more clearly understood, with reference to embodiment and accompanying drawing, to this
Invention is described in further detail, and exemplary embodiment of the invention and its explanation are only used for explaining the present invention, do not make
For limitation of the invention.
Embodiment 1
As depicted in figs. 1 and 2, the present embodiment includes the support column 2 of inner hollow, is opened in the side wall of the support column 2
There are multiple rectangular openings 6, the bottom of support column 2 is provided with multiple spacing holes 8 being connected with each other with rectangular opening 6, the middle cavity of support column 2
The support bar 7 of taper is fixed with vivo, and multiple claws 3 are connected with the side wall upper hinge of the support bar 7；Also include being fixed on
The electromagnet 95 on the top of support bar 7, electromagnet 95 are connected by wire with external power source, and in claw 3 close to the side of support bar 7

During present invention work, rectangular opening 6 forms L-shaped activity interval of the claw 3 on support bar 7 with spacing hole 8, will support
Post 2 is slowly put into oil well, while startup power supply so that electromagnet 95 interacts with the magnet on claw 3, i.e. electromagnet
95 pairs of magnet 9 produce the upper end for attracting to cause claw 3 and inwardly bounced back around pin joint, and the other end of claw 3 is outside around pin joint
Expansion so that the inner space increase for the column grasping part that multiple claws 3 are formed, that is, ensure that claw 3 can be to oil well
Whole internal debris, crushed stone, steel wire rope, cable rope etc. is cleared up；When the bottom of claw 3 is placed in shaft bottom,
Electric current in electromagnet 95 is passed through to change so that attraction state of the electromagnet 95 to magnet 9 is changed into repulsion state, claw 3 it is upper
End starts away from electromagnet 95, and its other end is then close to place where the axis of support column 2, and then so that debris in oil well
Deng the grasping part for entering multiple claws 3 and being formed, when the ends contact of inwall and the spacing hole 8 of claw 3, claw 3 stop after
Continuous movement, prevent multiple claws 3 each other excessive movement and cause to be damaged；Further to strengthen salvaging effect of the claw 3 to debris
Fruit, latch 4 is installed on claw 3, prevents debris from being dropped in uphill process is salvaged；Multiple annular arrays of claw 3 are hinged on
On support bar 7 so that multiple claws 3 form a coniform grasping part, to ensure that claw 3 is complete to the debris in oil well
All clear is managed.
Further, connector 1 is used to be connected with the lowering or hoisting gear of outside, and the lowering or hoisting gear can be steel cable or traction
Bar, the related debris of structure will be salvaged by the lifting of steel cable or draw bar and removed together in oil well.
