Abstract
The utility model discloses a wear-resistant corrosion-resistant sucker rod with a clamping sheath, and is particularly suitable for a sucker rod with an outer anti-corrosive layer. The wear-resistant corrosion-resistant sucker rod disclosed by the utility model comprises a rod body (1), a protective layer (2) and an end part screw thread (8), wherein the end part screw thread (8) is provided with the clamping sheath (7) which is matched with the end part screw thread (8); the clamping sheath (7) is made of stainless steel or other anti-corrosive materials; a filler (3) is filled in a gap between the clamping sheath (7) and the rod body (1) of the sucker rod; the filler is a nonmetallic anti-corrosive material; a unloading groove (6) is arranged between the end part screw thread (8) of the sucker rod and a thickening section (5) of the rod body (1); the clamping sheath (7) is screwed on the end part screw thread (8); and an exposed part of the end part screw thread (8) can be connected with a coupling of a conventional sucker rod. When the coupling is loaded or unloaded, a spanner clamps the clamping sheath (4), the anti-corrosive layer, at the spanner, of the sucker rod with the anti-corrosive layer can be prevented from being bitted, accordingly, the corrosion-resistant capability of the sucker rod can be improved, and the service life can be prolonged.
Description
Technical field:
The utility model relates to the wear-resistant anti-rotten sucker rod that a kind of strap clamp is held sheath, is specially adapted to the sucker rod of external anti-corrosion layer.
Background technology:
The outer anti-corrosion pumping bar that uses mainly contains outer wall coating, injection moulding at present, or the form of outer wall plating, but a shortcoming of this outer wall anti-corrosion pumping bar is, on when unloading place, spanner side external anti-corrosion layer stung card by spanner, expose body, produce local corrosion after going into the well, easily cause sucker rod to lose efficacy, influence sucker rod application life.
Summary of the invention:
The purpose of this utility model provides the wear-resistant anti-rotten sucker rod that a kind of strap clamp is held sheath, connects or when dismantling sucker rod, spanner blocks the clamping sheath, can avoid the corrosion of sucker rod concentration of local to cause inefficacy, prolongs outer anti-corrosion pumping bar application life.
The utility model is by the body of rod; topping; end thread is formed; its end thread is provided with a clamping sheath that is mated; the clamping sheath is stainless steel or other anticorrosive; gap between clamping sheath and the sucker rod body of rod is filled by filler; filler is nonmetal anti-corrosion material; have the flash hole on the clamping sheath; after filler is full of fully; flash and flash removal is clean; one thick section is arranged between sucker rod end thread and the body of rod; one compensating groove is arranged between end thread and the thick section; between thick section and the body of rod transition arc is arranged; the clamping sheath is twisted and is connected on the end thread; the part that end thread is exposed can be connected with conventional rod collar, smears encapsulant before buckleing on the end thread of clamping sheath and sucker rod, prevents that liquid from entering thread pitch and causing corrosion; gap between clamping sheath and sucker rod transition arc is filled by filler, guarantees that the transition arc place does not have the bulk material of naked leakage.On when unloading box cupling, spanner is clamped on the clamping sheath, can avoid place, external anti-corrosion layer rod tong side anticorrosive coat to be bitten, thereby improves the anti-corrosion capability of sucker rod, increases the service life.
The utility model is simple in structure, and is easily manufactured, can avoid the anticorrosive coat at rod tong side place to be bitten during operation, can improve external anti-corrosion layer pumping rod anti-corrosive ability greatly, prolongs sucker rod application life.
Description of drawings:
Fig. 1 is the utility model structure principle chart
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is described in detail:
The utility model is by the body of rod (1); topping (2); end thread (8) is formed; its end thread (8) is provided with a clamping sheath (7) that is mated; clamping sheath (7) is stainless steel or other anticorrosive; gap between clamping sheath (7) and the sucker rod body of rod (1) is filled by filler (3); filler (3) is nonmetal anti-corrosion material; the clamping sheath has the flash hole on (4); after filler is full of fully; flash and flash removal is clean; between sucker rod end thread (8) and the body of rod (1) thick section (5) is arranged; between end thread (8) and thick section (5) compensating groove (6) is arranged; between thick section (5) and the body of rod (1) transition arc (4) is arranged; clamping sheath (7) is twisted and is connected on the end thread (8); the part that end thread (8) is exposed can be connected with conventional rod collar; clamping sheath (7) is smeared encapsulant before upward buckleing with the end thread (8) of sucker rod; prevent that liquid from entering thread pitch and causing corrosion; gap between clamping sheath (7) and sucker rod transition arc (4) is filled by filler (3), and assurance transition arc (4) locates not have the bulk material of naked leakage.On when unloading box cupling, spanner is clamped on the clamping sheath (4), can avoid place, external anti-corrosion layer rod tong side anticorrosive coat to be bitten, thereby improves the anti-corrosion capability of sucker rod, increases the service life.
Claims (2)
1. a strap clamp is held the wear-resistant anti-rotten sucker rod of sheath; by the body of rod (1); topping (2); end thread (8) is formed; it is characterized in that end thread (8) is provided with a clamping sheath (7) that is mated; gap between clamping sheath (7) and the sucker rod body of rod (1) is filled by filler (3); between sucker rod end thread (8) and the body of rod (1) thick section (5) is arranged; compensating groove (6) between end thread (8) and thick section (5); between thick section (5) and the body of rod (1) transition arc (4) is arranged; clamping sheath (7) is twisted and is connected on the end thread (8), and the gap between clamping sheath (7) and sucker rod transition arc (4) is filled by filler (3).
