The certainly inversive fastening pumping rods tool of inversive fastening pumping rods problem.
Background technique
The principal contradiction of loose sand oil accumulation exploitation is exactly sand production, Gao Hansha, High water cut media environment make often
The average pump detection period for advising plunger oil-well pump is shorter and shorter, and sand card column plug often occurs in oil well pump, sand buries sucker rod or long-time
The accidents such as oil pumping rod centering device local shedding card piston are produced, so that oil well pump premature failure.For this purpose, when card sucker rod thing occurs
Therefore when, it needs to carry out back-off processing to sucker rod.Currently, scene is generally buckled to sucker rod using pipe wrench using manpower, not only deposit
In security risk, and it is time-consuming and laborious, and construction period is longer.
Therefore, a kind of tool easy to operate, safely and effectively carrying out back-off sucker rod is needed, manpower is solved and is buckled to sucker rod
Security risk problem, shorten construction period.
Utility model content
It is easy to operate technical problem to be solved by the utility model is to provide a kind of inversive fastening pumping rods tool, safely may be used
It leans on, eliminates security risk of the manpower using pipe wrench back-off sucker rod when, reduce security risk, improve working efficiency.
The technical solution adopted in the utility model is: a kind of inversive fastening pumping rods tool, including tool body, fastening nut,
Fastening bolt rotational pin, rotation connection pin, pincers tooth and mounting groove, tool body are the two halves symmetrical structure splitted among cylinder,
It is divided into tool body left part and tool body right part, tool body left part and tool body right part pass through upper and lower two rotation connections
It sells hinged, forms opening and closing left and right, it is symmetrical another with rotation connection pin on tool body left part and tool body right part
Side has a mounting groove, and 2 fastening bolt rotational pins are hinged on the ipsilateral of tool body left part or tool body right part
In upper and lower two mounting grooves, the outside movable end vehicle of fastening bolt rotational pin has the screw thread being adapted with fastening nut, using tight
Gu the mounting groove that bolt rotational pin is inserted into the other half tool body is fixed nut, at the inboard center of tool body cylinder
Position upper and lower ends are machined with pincers tooth, are inserted into the mounting groove of the other side by the fastening bolt rotational pin of side, utilize fastening
Nut is tightened, and pincers tooth is made securely to be engaged sucker rod.
The pincers tooth is the oblique conical form formed by way of wire cutting.
The beneficial effects of the utility model are: the inversive fastening pumping rods tool is easy to operate when carrying out inversive fastening pumping rods, peace
Entirely reliably, installation and debugging can be completed in one when construction, and operation hydraulic tongs machinery is buckled to sucker rod, eliminate manpower and use pipe wrench
It is buckled to security risk existing for sucker rod, security risk and labor intensity is reduced, improves work efficiency.

Specific embodiment
Illustrate specific embodiment of the present utility model with reference to the accompanying drawing:
As shown in Figure 1-3, the inversive fastening pumping rods tool of the utility model, including tool body 1, fastening nut 2, fastening spiral shell
Bolt rotational pin 4, rotation connection pin 3, pincers tooth 5 and mounting groove 6, tool body 1 are the two halves symmetrical structure splitted among cylinder, point
Pass through upper and lower two for tool body left part 1-1 and tool body right part 1-2, tool body left part 1-1 and tool body right part 1-2
A rotation connection pin 3 is hinged, forms opening and closing left and right, on tool body left part 1-1 and tool body right part 1-2 and turns
The dynamic symmetrical other side of connecting pin 3 has 6,2 fastening bolt rotational pins 4 of mounting groove and is hinged on tool body left part 1-1
Or in ipsilateral two mounting grooves 6 up and down of tool body right part 1-2, the outside movable end vehicle of fastening bolt rotational pin 4 have with
The adaptable screw thread of fastening nut 2, using fastening nut 2 by bolt rotational pin 4 be inserted into the mounting groove 6 of the other half tool body into
Row is fixed, and is machined with pincers tooth 5 in the inboard centre upper and lower ends of 1 cylinder of tool body, is turned by the fastening bolt of side
Dynamic pin 3 is inserted into the mounting groove 6 of the other side, is tightened using fastening nut 2, makes to clamp the securely occlusion sucker rod of tooth 5.
The pincers tooth 5 is the oblique conical form formed by way of wire cutting.
Specifically, the tool body left part 1-1 and tool body right part 1-2 connect in the rotation of rotation connection pin 3
A cylinder is formed after connecing lower fastening.In the centre upper and lower ends of tool body left part 1-1 and tool body right part 1-2
Pincers tooth 5 is processed by the way of wire cutting.When tool body or so two 1-1 and 1-2 are fastened, pincers tooth 5 can be engaged oil pumping
Bar.At this point, fastening bolt rotational pin 4 is inserted into the mounting groove 6, upper and lower fastening nut 2 is manually tightened using spanner, tightly
Gu nut 2 is twisted tighter, pincers tooth 5 is engaged the more secured of sucker rod.During inversive fastening pumping rods tool use, first should
Tool is fastened on sucker rod, tightens fastening nut 2;Then the tool body after being fastened using hydraulic tongs occlusion is realized mechanical
It is buckled to sucker rod.
Its working principle is that: in the pincers tooth of the central part upper and lower ends wire cutting high intensity of tool body, in tool sheet
When the two halves structure pairing of body, for being engaged sucker rod.When the two halves structure pairing of tool body, fastening bolt rotational pin is inserted
Enter in locking head, upper and lower fastening nut is manually tightened using spanner, fastening nut is twisted tighter, and pump rod is engaged more secured.
During the pump rod reversing tool use, the tool is fastened on sucker rod first, tightens fastening nut;Then it utilizes
Hydraulic tongs biting instrument ontology realizes mechanical back-off sucker rod.
In conclusion the content of the utility model is not limited to the above embodiments, the knowledgeable people in same area
It can propose other embodiments easily according to the technological guidance's thought of the utility model, but this embodiment is included in this reality
Within the scope of novel.
