CN2903344Y - Multifunctional rope hanging device of oil pumping machine - Google Patents

Abstract

The oil pumping machine multi-functional rope suspending device is a device suspending the down-hole load of oil pumping machine, which overcomes the previous shortcomings and comprises a main body, an anti-twist bearing, a dish-shaped spring, a block plate groove, a block plate bolt hole, a vibration damping spring groove, a block plate, a stabilizing tooth piece and a adjusting top wire. The dish-shaped spring is disposed inside the vibration-dumping spring groove on the upper portion of the main body and the anti-twist bearing is fixed inside a hair braid plummet groove. The block plate is connected with the block plate bolts and the block plate bolt holes and is fixed inside the block plate groove. The adjusting top wire which is provided with the stabilizing tooth piece is connected with the block plate through threads. The oil pumping machine multi-functional rope suspending device can automatically adjust the suspending position of the oil pumping machine polish rod, prevent the square clips from rolling up with vibration-dumping function while bearing the load, and prevent oil dumping machine hair braid from twisting and is characterized by comprehensive complement operational technique, strong specialty, high safety degree and long life in use.

Description

The multi-functional polished rod eye of oil pumper

One, technical field: the utility model relates to the multi-functional polished rod eye of a kind of device, especially oil pumper that oil pumper hangs down-hole load.

Two, background technology: polished rod eye is the capital equipment that oil pumper hangs down-hole load, in oil pumper day-to-day operation process, because the unreasonable structure of old-fashioned polished rod eye, the preposition other horse head of polished rod appears when eating load, the hair plait is beaten and is turned round, and square clamp strip damages phenomenons such as tester, seriously affect the normal operation of oil pumper, our every work has all been produced tremendous influence.

Three, summary of the invention: the purpose of this utility model provides the multi-functional polished rod eye of a kind of oil pumper rational in infrastructure, handling safety, it has overcome the shortcoming of original device, the purpose of this utility model is to realize like this, it be by main body, anti-beat turn round bearing, disk spring, baffle plate groove, baffle plate bolt hole, shock-absorbing spring groove, baffle plate, set upright block teeth, the adjusting jackscrew is formed by connecting, disk spring is positioned at the top shock-absorbing spring groove of main body; Anti-beating turned round bearing fixing in hair plait plummet groove; Baffle plate is connected by baffle plate bolt, baffle plate bolt hole with main body, and is fixed in the baffle plate groove; Regulate jackscrew and baffle plate by screwed connection; Setting upright block teeth is connected on the adjusting jackscrew.

This device can be regulated the hanging position of oil-extractor polish-rod automatically; Automatically the side's of preventing clamp strip and shock-absorbing function is arranged when it eats load; Can prevent automatically that oil pumper hair plait from beating turns round; Operating technology is supporting comprehensive, strongly professional; The safety factor height; Long service life.
