Abstract
The utility model provides a block hoop type position-restricting equipment, which is used for the axial displacement of the movable equipment which are limitation centralizer, wax scraper, etc. in the oil production with bars. The utility model is characterized in that a pumping rod is tightly sheathed through utilizing an elastic cushion in a block hoop and the friction force among the pumping rods; the position-restricting is realized. The utility model has the advantages of no specific requirements to the surface of the pumping rod, simple structure, and direct mounting at job sites.
Description
The invention belongs to oil has in the bar oil recovery, is installed in the stopping means on the sucker rod.Be used for limiting the axial displacement of heads such as the centralizer that is installed on the sucker rod, paraffin scraper.
Existing steel loop adhesion type stopping means is with bonding agent two semicircle steel loops to be bonded on the sucker rod, twines bonding reinforcing with thin wire and glass fabric again and forms.Its axial bearing capacity is big, but the adhesive linkage impact strength is low, and interface is easily aging.Another kind is a nylon packaging type guide position limiter, and a side of this device has gathering sill, block sucker rod after, pack tightly by the elastic force and the sucker rod of nylon spare self.Its axial bearing capacity is little, and appearance and size is big, is not suitable for using in the higher oil well of viscosity.
Task of the present invention provides the clamping hoop type stopping means that a kind of soft contact machine is installed.It can adapt to the well site assembled condition, can produce bigger axial bearing capacity, and the sucker rod surface quality is not had specific (special) requirements.
Content of the present invention: utilize mechanical clamping force with clip (1) chucking, the horizontal bar elasticity of compression rubber cushion (2) of clip (1) inner bulge packs tightly sucker rod by the frictional force between elastic rubber fitting (2) and the sucker rod.Clip (1) pins straight pin (3) under the expansion force effect of elastic rubber fitting (2).The size of package power can be adjusted by the elastic rubber fitting (2) of changing different-thickness.After adopting material to be the elastic rubber fitting (2) of oil resistant rubber, elastic rubber fitting (2) can have long application life.
Concrete implementation method: with 1 straight pin (3) two clips (1) are connected into the openable hinge bodies of a side hinge opposite side earlier, in clip (1), pack into behind the elastic rubber fitting (2), from pack into the precalculated position of sucker rod of open side, exert pressure in clip (1) both sides, make elastic rubber fitting (2) compression tightly be wrapped on the sucker rod, pin is gone into another straight pin (3) up to open side pan alignment back, and the direction of latch has an end of cap to make progress.
Description of drawings: accompanying drawing is represented the assembling schematic diagram and the A-A sectional view of stopping means.Tubing string is partly illustrated in double dot dash line.The entire infrastructure of stopping means as can be seen from the accompanying drawing.
Claims (3)
1, a kind of oil has bar to be used to limit the stopping means of head position on the sucker rod in recovering the oil, and it is characterized in that stopping means is made up of clip (1), elastic rubber fitting (2) and straight pin (3).
2, stopping means according to claim 1 is characterized in that there is the horizontal bar of some projectioies described clip (1) inboard.
3, stopping means according to claim 1 is characterized in that described elastic rubber fitting (2) can be an oil resistant rubber.
