Grease injection head horn mouth oil scraping device

Abstract

The invention provides a grease injection head horn mouth oil scraping device. The grease injection head horn mouth oil scraping device comprises a support; a pressing block is arranged in the centerof the support; the center of the pressing block centralizes a cable and scrapes grease; a support inner cavity is formed in the upper end of the support; an oil discharge hole is formed in the bottomend of one side of the support inner cavity; a lower pressing plate is mounted at an opening in the upper end of the support; a through hole II is formed in the center of the lower pressing plate; amiddle pressing plate is arranged at the upper end of the lower pressing plate; an oil scraping packing of a C-shaped structure is mounted in the center of the middle pressing plate; an upper pressingplate is arranged at the top end of the middle pressing plate; the upper pressing plate, the middle pressing plate, the lower pressing plate and the support are fastened and connected into a whole through vertical bolts; middle embedded blocks are mounted in notches formed in the middle pressing plate; compression springs are mounted between two sets of middle embedded blocks through horizontal bolts; the middle embedded blocks and a middle pressing block are elastically connected into a whole through horizontal bolts; and meanwhile the middle embedded blocks extrude and push the oil scrapingpacking to scrape off the grease on the cable. The device is simple and compact in structure, safe, reliable, convenient and fast to assemble, convenient to disassemble and replace, economical, energy-saving, environment-friendly, more user-friendly and more efficient in scraping.

Description

technical field [0001] The invention belongs to the technical field of oilfield wellhead equipment, and in particular relates to a bell mouth oil scraping device of a grease injection head. Background technique [0002] The traditional bell mouth has a guiding function, but as the requirements for work efficiency become higher and higher, the single guiding function of the bell mouth can no longer meet the requirements of efficiency and environmental protection. [0003] The announcement number is CN208564508U, which discloses an online oil well head cleaning device for oil well minor repair operations; and the oil scraping plate and oil scraping device with announcement number CN210483646U. The common problems are that the structure is scattered, and the number of parts is too large, which is not conducive to miniaturization design. , and the assembly is complicated; especially after the wearing parts are damaged, it is not easy to quickly disassemble and replace them.
