Technical field
This utility model belongs to underground work technical field, particularly to the down-hole steel wire unfreezing fishing power tool during Oil/gas Well well workover, and a kind of pull bar hammer.
Background technology
Soviet Union's Sulige gas field exploitation uses downhole choke technology, underground throttle device is relied on to realize pit shaft reducing pressure by regulating flow, utilize ground temperature to heat so that after throttling, well head gas flow temperature substantially returns to the front temperature that throttles, reduce well head and the pressure of surface gathering system, simplify and optimize ground flow.
Along with the exploitation in gas field, well yield is more and more lower, and minority stripper well produces abnormal because of hydrops.For meeting Production requirement, gas well yield to be regulated or water pumping gas production measure to be carried out are to give full play to gas well deliverability, thus need to salvage reducer from pit shaft.
Underground throttle device salvages the main steel wire operation mode that uses, general use carry on directly or under pound directly to hit on instrument or under hit power so that it is solution be honored as a queen on mention.Because hydrops, fouling etc. affect, often occur reducer cannot unseal, solution be honored as a queen on put forward the situations such as difficulty of salvaging such as motionless, be therefore badly in need of developing a kind of instrument improving jarring force, hit under solving to cause because jarring force is little motionless, on put forward the problems such as chance card.
Utility model content
The purpose of this utility model is to develop a kind of instrument improving jarring force, hit under solving to cause because jarring force is little motionless, on put forward the chance problem such as card.
For this, this utility model provides a kind of pull bar hammer, including top connection, cylinder sleeve, piston, piston rod, urceolus, tail joint and female joint, top connection lower end and the screwed connection of cylinder sleeve upper end, cylinder sleeve lower end and the screwed connection of urceolus upper end, urceolus lower end and tail joint screwed connection；Piston embeds in cylinder sleeve, and piston rod upper end and piston screwed connection, piston-rod lower end and female joint screwed connection, tail fitting sleeve is on the piston rod.
The outer wall of described piston is provided with groove, is installed with piston ring in groove.
Described piston ring is provided with 2 or multiple.
Described piston ring is band breach ring segment.
Multiple bore hole is had on described urceolus.
Described top connection outer wall is irregular roundness cylindricality, is provided with two quad flat districts relatively set on the face of cylinder.
Sealing ring is had between described top connection and cylinder sleeve.
The beneficial effects of the utility model: this pull bar hammer that this utility model provides, mainly utilize the effect of inertia force and gravity, and reducer is produced jarring force, this structure of the present utility model, can produce bigger jarring force in operation, deblocking is hit, it is possible on carrying out, hit unfreezing under for.

Detailed description of the invention
Embodiment 1:
The present embodiment provides a kind of pull bar hammer, as shown in Figure 1, including top connection 1, cylinder sleeve 3, piston 5, piston rod 6, urceolus 7, tail joint 8 and female joint 9, top connection 1 lower end and cylinder sleeve 3 upper end screwed connection, cylinder sleeve 3 lower end and urceolus 7 upper end screwed connection, urceolus 7 lower end and tail joint 8 screwed connection；Piston 5 embeds in cylinder sleeve 3, piston rod 6 upper end and piston 5 screwed connection, piston rod 6 lower end and female joint 9 screwed connection, and tail joint 8 is enclosed within piston rod 6, has sealing ring 2 between top connection 1 and cylinder sleeve 3.
The installation process of the present invention is as follows:
By threaded to top connection 1 and cylinder sleeve 3, cylinder sleeve 3 and urceolus 7 are threaded, piston ring 4 puts into cylinder sleeve 3 inner chamber, piston rod 6 and piston 5 are threaded, piston 5 puts into cylinder sleeve 3 inner chamber, tail joint 8 is inserted in after piston rod 6 and urceolus 7 is threaded, female joint 9 and threaded through piston rod 6 lower end of tail joint 8.
The work process of the present invention is as follows:
Transfer to close after on reducer by the present invention with steel wire, on carry steel wire 1m, piston 5 is the most descending because of effects such as bottom weighted levers, after arriving urceolus 7 inner chamber, the instrument freely falling bodies such as the piston rod 6, female joint 9 and the bottom weighted lever that are attached thereto are descending, reducer is produced jarring force, it is possible to resolve the problem that conventional bumper jar jarring force is little.
Embodiment 2:
The present embodiment improves on the basis of embodiment 1 further, and in the present embodiment, the outer wall of piston 5 is provided with groove, is installed with piston ring 4 in groove, and piston ring 4 is provided with 2 or multiple, and piston ring 4 is band breach ring segment.
Piston ring is a kind of metallic elastic ring having and expanding outwardly more greatly deformation, and it is mounted in its corresponding cannelure of section.Reciprocal and the piston ring of rotary motion, rely on gas or the pressure differential of liquid, formed between ring periphery and cylinder and ring and a side of annular groove and seal, piston ring 4 in the present embodiment ensure that and is completely blocked out between the upper and lower cavity of piston 5, above it, in cylinder sleeve 3, intracavity is an independent sealed cavity, it is connected to the tubing string of top by top connection 1, and the cavity below piston 5 can form one with urceolus 7, not relevant with top cavity.
Embodiment 3:
Can be seen that from above-mentioned two embodiment, this structure of the present utility model, mainly by piston rod 6 and piston 5, the instrument freely falling body descending formation impulse forces such as female joint 9 and bottom weighted lever carry out jarring, owing to piston rod 6 and piston 5 are in cylinder sleeve 3 and urceolus 7 inner space, if do not communicated with outside, piston rod 6 and piston 5 can be obstructed due to gas pressure during declining, therefore, in the present embodiment, urceolus 7 is provided with multiple bore hole, so, in piston rod 6 and piston 5 dropping process, can remain that urceolus 7 external pressure communicates with inside, do not affect piston rod 6 and piston 5 is descending.
Embodiment 4:
The present embodiment improves on the basis of above-mentioned several embodiments further, due in this utility model annexation between all parts mainly by threaded form, this connected mode makes solid tool to dismantle, maintenance maintenance is the most more convenient, and it is known that, some large-scale apparatuses are during dismounting, owing to apparatus great majority are cylindrical, it is readily formed instrument landing when using extracting tool, the most bad apparatus is dismantled, it is also easy to apparatus is caused damage, for these features, in the present embodiment, top connection 1 outer wall is set to irregular roundness cylindricality, the face of cylinder is provided with two quad flat districts relatively set.
Such structure, during pull bar hammer is removed and installed, with pipe wrench be clamped on top connection 1 face of cylinder relatively and in the quad flat district set, can ensure during removing and installing, it is stronger to accommodate ratio, does not easily cause the scuffing of top connection 1.
In sum, this pull bar hammer of the present utility model, utilize the effect of inertia force and gravity, reducer is produced jarring force, this structure of the present utility model, bigger jarring force can be produced, under being used for, hit deblocking, it is possible on carrying out, hit unfreezing in operation.Solve hit under causing because jarring force is little motionless, on put forward the chance problem such as card.
Exemplified as above is only to illustration of the present utility model, is not intended that the restriction to protection domain of the present utility model, within the every and same or analogous design of this utility model belongs to protection scope of the present invention.
