A centralizer that is convenient and quick to disassemble

Abstract

The invention provides a centralizer convenient and quick to disassemble and assemble. The centralizer comprises a centralizer body, an oil guide groove, a rotating shaft, a ball bearing, a bottom plate connecting sleeve, a convenient detachable connecting threaded column structure, an adjustable centralizer fixing hoop sheet structure, an anti-drop convenient detachable handle structure, a connecting pipe seat, a pulley, a clamping seat, a nameplate sticker, an anti-corrosion layer, a convenient detachable lug plate, a crowbar inserting hole and a slidable adjusting supporting seat structure,wherein the oil guide groove is formed in the front surface of the centralizer body; the rotating shaft is connected to an inner ring of the ball bearing in an inserting mode. According to the centralizer, the arrangement of the connecting threaded column, a wrench clamping block, a through hole and an arc-shaped convex block is beneficial to the installation and disassembly of the centralizer byusing different tools; and the arrangement of a limiting stop dog plate, a first dismounting connecting pipe, a second dismounting connecting pipe, a convenient detachable hand grip, a connecting steel ring and a rubber convex ball is favorable for adjusting and lengthening when the centralizer is assembled and disassembled , and the use convenience is increased.

Description

technical field [0001] The invention belongs to the technical field of centralizers, in particular to a centralizer which is convenient and quick to assemble and disassemble. Background technique [0002] In the process of oil production in my country, the sealing of the wellhead polished rod of the oil pumping unit directly affects the output of crude oil and the working time of the oil well. At present, there are many oil wells in production in various oil fields in my country. The existing problems are: first, crude oil leakage or large-scale pollution caused by the eccentric wear of the polished rod; fast, resulting in an increase in workload, the main problem is that the centralizing body and support rods are prone to jamming, which is equivalent to ordinary eccentric wear section hoops after jamming; the cost is high and the price is relatively expensive, which affects the scope of on-site promotion and use. [0003] Stabilizer, also known as centralizer, is a tool for ...
