Abstract
The utility model discloses a pumping unit polished rod rotation shock absorber which belongs to the technical field of pumping units and solves the problem that a pumping unit polished rod clamp and a wire rope suspended supporting plate on the pumping unit horse head impact and collide easily. The shock absorber comprises an inner sleeve, an outer sleeve, a bearing, a spring and a base sleeve, wherein the surface of the top outer edge of the outer sleeve and the lower surface of the top outer edge of the inner sleeve are provided with right-angled grooves; the inner sleeve is sheathed with the outer sleeve through the bearing in the groove; the bottom of the inner sleeve is connected with a pressure plate through a bolt; the lower surface of the top outer edge of the outer sleeve presses against the top end of the spring; the bottom of the spring presses against the lower surface of the top outer edge of the base sleeve; the pushing surface is fixed by means of welding; and the top outer edge of the inner sleeve is welded with a dirt-proof boot. The shock absorber has the characteristics of long service life, simple structure, convenient installation, reliable performance and low cost, and can effectively protect the pumping unit polished rod and the polished rod clamp and prolong the service life of a motor.
Description
One, skill is stated field the utility model and is belonged to the oil pumper technical field, particularly relates to a kind of oil-extractor polish-rod damping device.
Two, background technology is present, beam pumping unit is a kind of mechanical oil recovery equip ment that generally adopt in the oil field, particularly when the heavy crude producing oil field, polished rod twisting and polished rod down stroke and the nonsynchronous situation of pumping unit horsehead appear in oil pumper easily, make the wire rope suspensioning supporting plate on polished rod clamp and the pumping unit horsehead that impact often take place, cause polished rod and polished rod clamp to damage easily, can influence the normal operation of oil pumper when serious, even causing accidents such as stopping production frequently to take place, field maintenance is time-consuming, effort and dangerous.
Three; the summary of the invention the purpose of this utility model provides a kind of oil-extractor polish-rod rotary vibration damper; solved the problem that impact often takes place for wire rope suspensioning supporting plate on oil-extractor polish-rod clamp and the pumping unit horsehead; it comprises inner sleeve; outer sleeve; bearing; spring and base sleeve; be provided with right angle groove below outer sleeve top outer fringe surface and the inner sleeve top outer rim; inner sleeve is by being arranged on bearing and the outer sleeve socket in the groove; be connected with platen by bolt in the inner sleeve bottom; offset with the spring top below the outer rim of outer sleeve top; offset below spring bottom and the base sleeve top outer rim; conflict face is fixing by welding; outer rim is welded with dirt-proof boot on the inner sleeve top; has long service life; simple in structure; easy for installation, dependable performance, characteristics with low cost; can protect oil-extractor polish-rod and polished rod clamp effectively, prolong the application life of motor.
