Description
Technical field
The present invention relates to oil field, and in particular to the pneumatic oil well of drawing and pulling type salvages structure.
Background technology
The junk of some influence operations and oil exploitation, usually one can be usually fallen into during oil well operation, in oil well
A little steel wire rope, cable, steel wire for logging etc. are elongated and the soft object of body, 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 salvage not thorough enough, the shorter thing that drops of many tiny, length is difficult to be salvaged, and causes the salvaging cycle also to extend.
The content of the invention
Structure is salvaged it is an object of the invention to provide the pneumatic oil well of drawing and pulling type, the conventional rope instrument that drags for is solved and beats
Drag for that efficiency is low, salvage halfway problem；Realize it is a kind of it is simple in construction, can be shorter to tiny, length drop and thing or be stuck in well
The column cap at bottom drops thing and rope form junk while the purpose for the fisher salvaged.
The present invention is achieved through the following technical solutions：
The pneumatic oil well of drawing and pulling type salvages structure, includes the support column of inner hollow, support column bottom is provided with one
A salvaging through hole is provided with the fishing socket that individual center line is overlapped with the center line of support column, the fishing socket, the salvaging is led to
Hole is communicated with support column internal cavities, and the diameter for salvaging through hole reduces on axis towards the dimension linear close to support column；Also wrap
Include the support bar being partially disposed in inside support column, one end of the support bar is connected with the handle positioned at support top end, another
End is connected with piston, and the piston is matched with support column wall；At least two crotches are additionally provided with fishing socket bottom, it is described curved
The inner concave of hook points to support column.Further, the present invention devises a kind of new fisher, and concrete structure is as noted above,
The thing that drops that nozzle alignment needs to salvage will be salvaged, handle, makes piston be moved towards the direction away from fishing socket then up, because
For support column long enough, during piston movement, salvage nozzle can to support column direction air-breathing, form negative pressure so that fall
Junk is firmly adsorbed in fishing socket；Compared with prior art by the way of electromagnetic adsorption drops thing, the present invention uses pneumatic side
Formula structure is simpler, economic and environment-friendly.The fisher can also be used to extracting the column cap for being stuck in shaft bottom and drop thing, will salvage through hole and hangs down
The straight column cap that blocks drops thing, and will salvage via design is that diameter reduces on axis towards the dimension linear close to support column
Structure so that the column cap that the present invention can block different-diameter drops thing, has widened the scope of application of the present invention.At fishing socket bottom
End is additionally provided with least two crotches, and the inner concave of the crotch points to support column, and crotch can be used for catching on rope form junk so that
The present invention shorter to tiny, length drop thing or can be stuck in the column cap in shaft bottom and drop thing simultaneously while rope form junk is caught on
Salvaged, improve salvaging efficiency.
It is preferred that, at least one set of support bar limit base, each support bar limit are additionally provided with the support column internal cavities
Position seat includes two arc dops, and the arc dop is symmetrical on the center line of support column, the outside wall surface of each arc dop
Fixed with support column internal cavities, the bar wall of internal face and support bar matches.Further, support bar and sky inside support column
There is gap between chamber, the present invention sets at least one support bar limit base to play position-limiting action to the direction of motion of support bar, kept away
Exempt from support bar to rock influence salvaging effect and cause piston wear.
It is preferred that, the cushion rubber layer of annular is additionally provided with the top end face of the support column.Further, in push-and-pull
During handle, cushion rubber layer is set to protect the hand of people, it is to avoid to strike support column and injured.
It is preferred that, anti-skidding protective case is also cased with the outside of support column, the anti-skidding protective case is close to support top end.Enter one
Step, the setting of anti-skidding protective case can strengthen the frictional force between people's palm of the hand and support column, it is to avoid rubber sleeve drops the present invention.
The present invention compared with prior art, has the following advantages and advantages：
The pneumatic oil well of drawing and pulling type of the present invention salvages structure, and a center line and support column are provided with support column bottom
The fishing socket that overlaps of center line, be provided with a salvaging through hole in the fishing socket, the salvaging through hole with it is empty inside support column
Chamber is communicated, and the diameter for salvaging through hole reduces on axis towards the dimension linear close to support column, causes the thing that drops using into negative pressure
Firmly adsorb in fishing socket；At least two crotches are additionally provided with fishing socket bottom, the inner concave of the crotch points to support
Post, crotch can be used for catching on rope form junk；The present invention it is applied widely, salvage efficiency high, it is environmental and durable the advantages of, production cost
It is low, it is applicable to industrial mass production.
