Abstract
The utility model relates to a paraffin scraper for a pump rod, which is mainly used for clearing greasy dirt, such as crude petroleum, paraffin, etc. on a pump rod. During workover operation, a pump rod lifted from a well has crude petroleum or paraffin with certain thickness, which can result in the problems of taking time and labor if the pump rod is repeatedly flushed and consuming water and electricity. The paraffin scraper for a pump rod, which is provided by the utility model, is composed of an upper and a lower circular discs, rollers, springs, steel wires, struts and strut rings. Because the upper and the lower circular discs of the structure can be mutually rotated, if rotated, the upper and the lower circular discs create relative displacement, and thus, a circular ring is formed by the steel wires in the paraffin scraper for a pump rod. The steel wires are tightly stuck to a pump rod body with certain tensioning force so as to fix the relative positions of the upper and the lower circular discs. In the process of lifting the pump rod, paraffin can be automatically scraped.
Description
Technical field
The utility model relates to a kind of pump rod paraffin scraper, is mainly used in greasy dirts such as the crude oil removed on the pump rod and paraffin, belongs to the special tool in the petroleum machinery.
Background technology
At present, in workover operation construction, the pump rod that proposes in the well often has certain thickness crude oil or wax, for removing these waxs, often need to rinse out wax on the pump rod with high steam, the pump rod surface needs that flushing several times could be clean repeatedly, waste time and energy, also cause water power consumption.
Summary of the invention
The purpose of this utility model is to provide the easy well head pump rod of a kind of convenience wax scraping apparatus, both has been convenient to remove wax on the pump rod etc., reach again save time, economize on water, economic purpose.
The utility model adopts following technical scheme: promptly a kind of pump rod paraffin scraper its by last, following two disks, roller, spring, steel wire, pillar and Zhi Zhuhuan constitute, it is characterized in that last, the center of lower disc has the pump rod through hole, by identical arc length several rollers are installed at interval on the periphery of last disk, the axis of each roller is all parallel with the tangent line of the last disk at this place, correspondence mounting column below roller, pillar is an angle steel, angle steel is outwards uncovered, mounting spring in the outside of angle steel is uncovered, the spring lower end is fixed on the Zhi Zhuhuan of pillar bottom, the spring upper end connects steel wire, the steel wire of spring upper end is walked around roller and is fixed on the lower disc, and pillar props up lower disc downwards, and the pillar ring set is in the lower disc outside.
In the said structure, 6-8 roller is installed usually on the periphery of last disk, steel wire is selected the steel wire of 3 mm dias for use, selects the spring of 5 kilograms of pulling force for use.
Also Zhi Zhuhuan can be installed in the upper end of pillar in the said structure, pillar and lower disc are linked together, Zhi Zhuhuan places the outside of disk, and spring is fixed on the pillar bottom.
Screw is arranged on Zhi Zhuhuan, when upper and lower disk rotation reaches requirement, use screw can temporarily fix the relative position of upper and lower disk by screw.
Operating principle of the present utility model is:
The pump rod paraffin scraper is installed on the operation well head, make pump rod pass on the paraffin scraper, the pump rod through hole of lower disc, because said structure, thereby two disks can rotate mutually up and down, when carrying out paraffin cutting with the pump rod paraffin scraper, disk in the rotation (or lower disc), making up and down, two disks produce relative displacement, then the steel wire in the pump rod paraffin scraper has just been formed an annulus, the angle of rotating is big more, the circle diameter that steel wire is formed is more little, and steel wire is close on the pump rod body with certain tensile force, and screw will be gone up by the screw of Zhi Zhuhuan, the relative position of lower disc is temporarily fixing, in putting forward the pump rod process, automatically finish the pump rod paraffin cutting, its wax that scrapes flows out from the slit of paraffin scraper, finishes the paraffin cutting operation.
