Background art:
in the process of drilling an oil field, a drill rod needs to be continuously additionally installed so as to achieve a sufficient depth, otherwise, the drill rod needs to be gradually removed after drilling is finished, and when the drill rod is installed and disassembled at present, a power mechanism is firstly utilized to drive two tong tooth plates to move relatively so that the two tong tooth plates can hold the drill rod tightly, a new drill rod can be installed at the upper end of the drill rod, or one drill rod on the upper portion of the drill rod is removed, so that the installation and the disassembly among different drill rods are completed.
At present, the tong die plate is all made by metal material to the interval is provided with the bar bead on the internal surface of tong die plate, with this clamping drilling rod, in the use, because the rigid contact causes drilling rod surface fish tail, serious can cause the drilling rod to scrap, has increased oil field manufacturing cost, and especially at present more and more oil field adopts the stainless steel drilling rod, and the manufacturing cost of stainless steel drilling rod is higher, and the economic loss who causes after scrapping is bigger.
The utility model has the following contents:
the utility model discloses the technical problem that will solve is: overcome prior art's not enough, provide a reasonable in design, change convenient and can reduce cost's oil field drilling rod dismouting with novel rubber tong die.
The technical scheme of the utility model is that:
the utility model provides a novel rubber tong dental lamina is used in dismouting of oil field drilling rod, contains tong dental lamina, tong dental lamina is the arc, its arc size and oil field drilling rod phase-match, be provided with the constant head tank on the intrados of tong dental lamina, be provided with curved rubber pad in the constant head tank, the extrados of rubber pad with the constant head tank laminating, the both ends of tong dental lamina are provided with the end plate respectively, the end plate is the semicircle crown plate.
Preferably, the two end plates are movably connected with the two ends of the tong die and fixedly connected through bolts; or one end plate is movably connected with one end of the tong tooth plate and fixedly connected with the other end of the tong tooth plate through a bolt, and the other end plate is fixedly connected with the other end of the tong tooth plate and fixedly welded or in an integrated structure.
Preferably, the inner arc surface of the rubber pad is provided with strip-shaped grooves at intervals, so that the friction coefficient and the sliding resistance are increased, the drill rod can be clamped at intervals, and the clamping firmness and stability are improved.
The utility model has the advantages that:
1. the utility model discloses set up the rubber layer at the internal surface of tong die, can eliminate the rigid connection between tong die and the drilling rod, reduce the damage to the drilling rod, adopt rubber lower and change easily as the bed course cost in addition.
2. The utility model discloses the interval sets up the strip recess on the internal surface of rubber pad, can form interval clamping drilling rod, increases coefficient of friction and sliding resistance, improves the fastness and the stability of centre gripping.
3. The utility model discloses the both ends of tong die are provided with the end plate, the dismouting rubber pad of being convenient for to can spacing rubber pad, guarantee that the rubber pad does not deviate from, the rubber pad adopts wear-resisting rubber to make simultaneously, long service life reduces use cost
4. The utility model relates to a rationally, change the convenience and can reduce cost, be applicable to clamping of oil field drilling rod, have good economic benefits after promoting.
Description of the drawings:
FIG. 1 is a schematic structural view of a novel rubber large tong die for disassembling and assembling a drill rod in an oil field;
fig. 2 is a top view of the novel rubber large tong die for dismounting the drill pipe in the oil field shown in fig. 1.
The specific implementation mode is as follows:
the first embodiment is as follows: referring to fig. 1-2, in the figure, 1-a large jaw plate, 2-a rubber pad, 3-a strip-shaped groove, 4-a positioning groove and 5-an end plate.
The dismouting of oil field drilling rod is with big tong dental lamina of novel rubber contains big tong dental lamina 1, and big tong dental lamina 1 is the arc, its arc size and oil field drilling rod phase-match, wherein: be provided with constant head tank 4 on the interior cambered surface of tong die 1, be provided with curved rubber pad 2 in the constant head tank 4, the outer cambered surface and the 4 laminating of constant head tank of rubber pad 2, the both ends of tong die 1 are provided with end plate 5 respectively, and end plate 5 is the semicircle ring board. The both sides limit of constant head tank 4 can shelter from the both sides of rubber pad 2, prevents that rubber pad 2 from deviating from the side of constant head tank 4, and end plate 5 can shelter from the both ends of rubber pad 2, prevents that rubber pad 2 from deviating from the both ends of constant head tank 4.
The preferable technical scheme is as follows: the interval is provided with bar recess 3 on the intrados of rubber pad 2, can form the clamping drilling rod of interval nature, improves the fastness and the stability of centre gripping, certainly, also can form bar bead, relies on bar bead to come the centre gripping drilling rod, and the two principle is the same, only the structure is different.
In addition, one end plate 5 is movably connected with one end of the large jaw plate 1 and fixedly connected with the other end of the large jaw plate 1 through a bolt (not shown in the figure), and the other end plate 5 is fixedly connected with the other end of the large jaw plate 1 and fixedly welded with the other end of the large jaw plate or integrally formed. With this structure, the end plate 5 can be removed, the rubber pad 2 can be inserted into the positioning groove 4 from the end, and then the end plate 5 and the tong die 1 are connected together to form a whole.
When the tool is used, the two tong die plates 1 are fixed on the power mechanism, the power mechanism is utilized to drive the two tong die plates 1 to move relatively, so that the two tong die plates 1 can tightly hold a drill rod, and the drill rod is disassembled and assembled. According to needs, rubber pad 2 adopts the rubber materials that have the wearability good, improves life.
Example two: the present embodiment is basically the same as the first embodiment, and the same points are not repeated, but the differences are: the two end plates 5 are movably connected with the two ends of the tong die 1 and fixedly connected through bolts; the structure is a split combined structure, is convenient to process and reduces the processing cost.
Example three: the present embodiment is basically the same as the first embodiment, and the same points are not repeated, but the differences are: the two end plates 5 are fixedly connected with the two ends of the large tong die 1 and are welded and fixed or in an integrated structure; this kind of structure has improved bulk strength, the rubber pad 2 under the exogenic action fill in within the constant head tank 4 can, because the rubber pad 2 has certain elasticity, can fill in constant head tank 4.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and any simple modifications made according to the technical spirit of the present invention are all within the scope of the technical solution of the present invention.
