Abstract
The utility model discloses a connector for an electric heating hollow oil pumping smooth rod. A bent pipe is installed on the left side surface of a connector body and obliquely and upward extends; an inner hole of the bent pipe is communicated with an inner hole in the lower part of the connector main body; a zero line fixed connector is installed on the right side surface of the connector main body; a heating cable guide pipe is mounted at the upper end of the bent pipe; an anti-abrasion lining tube is arranged in the inner hole of the bent pipe and the inner hole in the lower part of the connector main body; the lower part of the connector main body is in threaded connection with an externally hung connector; an internally hung connector is hung on the externally hung connector; a gasket ring is arranged between the upper end surface of the internally hung connector and the lower end surface of the connector main body; a hollow oil pumping rod thread is formed at the lower part of the internally hung connector; the anti-abrasion lining tube is arranged in the inner hole of the bent pipe and the inner hole in the lower part of the connector main body; the anti-abrasion lining tube is made of a non-metal material; the anti-abrasion lining tube has a very smooth surface and low hardness, a heating cable penetrates through the anti-abrasion lining tube, the heating cable cannot be abraded when the heating cable and the anti-abrasion lining tube move oppositely, so that the service life of the heating cable is prolonged, production stop and overhaul of an oil well are reduced, the oil well management difficulty is low, and the economic benefit is good.
Description
Technical field
The utility model is the instrument that hollow polished rod upper end that the oil field electric heating pumping well is used connects, and is the hollow oil pumping polish rod linkage of a kind of electrical heating.
Background technology
The joint that can obliquely wear cable of hollow polished rod upper end connection of electric heating pumping well, hollow polished rod is when moving back and forth along with oil pumper, the hollow rod of hollow polished rod bottom can extend shortening, and heating cable can not extend shortening, therefore, heating cable and inner nosepiece wall have relative motion, the inner nosepiece wall heating cable that can wear and tear causes heating cable often damaged, needs often to change maintenance, affect oil well production, increase the oil well management difficulty.
Summary of the invention
The purpose of this utility model is to provide the hollow oil pumping polish rod linkage of a kind of electrical heating, improves the application life of heating cable, reduces oil well and stops production and overhaul.
the purpose of this utility model is achieved in that and comprises bend pipe, body, the zero line anchor tip, the heating cable conduit, bend pipe is arranged on the body left surface, the oblique top of bend pipe, the endoporus of bend pipe communicates with the endoporus of body bottom, the body right flank is installed the zero line anchor tip, the heating cable conduit is arranged on the upper end of bend pipe, the endoporus of bend pipe, wear-resisting bushing pipe is arranged in the endoporus of body bottom, the body bottom is threaded with outer suspension joint, interior suspension joint is suspended on outer suspension joint, between interior suspension joint upper surface and body lower surface, joint ring is arranged, the hollow rod screw thread is arranged at interior suspension joint bottom.
The beneficial effects of the utility model are: in the endoporus of the endoporus of bend pipe, body bottom, wear-resisting bushing pipe is arranged, wear-resisting bushing pipe is nonmetals, its surface is very smooth, and hardness is low, after heating cable penetrates in it, when heating cable and wear-resisting bushing pipe relative motion, heating cable can not be worn, and can improve the application life of heating cable, reduces oil well and stops production and overhaul, the oil well management difficulty is little, and is good in economic efficiency.
Description of drawings
Accompanying drawing is the complete section figure of the utility model embodiment.
The specific embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described.
as seen from the figure, embodiment of the present utility model is by bend pipe 1, zero line anchor tip 2, body 3, wear-resisting bushing pipe 4, outer suspension joint 5, joint ring 6, interior suspension joint 7, heating cable conduit 9 forms, bend pipe 1 is arranged on body 3 left surfaces, the oblique top of bend pipe 1, avoid the heating cable bending excessive, the endoporus of bend pipe 1 communicates with the endoporus of body 3 bottoms, body 3 right flanks are installed zero line anchor tip 2, heating cable conduit 9 is arranged on the upper end of bend pipe 1, heating cable conduit 9 makes heating cable and zero line direction layout on request, the endoporus of bend pipe 1, wear-resisting bushing pipe 4 is arranged in the endoporus of body 3 bottoms, body 3 bottoms are threaded with outer suspension joint 5, interior suspension joint 7 is suspended on outer suspension joint 5, can relatively rotate between interior suspension joint 7 and outer suspension joint 5, between interior suspension joint 7 upper surfaces and body 3 lower surfaces, joint ring 6 is arranged, the sealing hollow polished rod is inner, hollow rod screw thread 8 is arranged at interior suspension joint 7 bottoms, can be connected with hollow polished rod.Its orientation can not change owing in bend pipe 1, cable being arranged, so body 3 can not rotate, therefore, the utility model will be realized by suspension joint in rotation 7 when being connected with hollow polished rod, therefore, adopt hang to fix between interior suspension joint 7 and outer suspension joint 5.
