Abstract
The utility model relates to a hydraulic unloading device for an oil pumping unit in the petroleum industry, which is used for unloading the oil pumping unit, and assists to complete the test work of the indicator card of an rod pumped well and other works such as the unloading of the oil pumping unit. The hydraulic unloading device comprises a loading bracket and a hydraulic lifting mechanism, wherein the hydraulic lifting mechanism is placed below the loading bracket. The hydraulic lifting mechanism comprises two hydrocylinders, an oil circuit fixing plate 2 and a hand-operated hydraulic pump, wherein a pressure release valve is arranged on the hand-operated hydraulic pump, the hydrocylinders are fixed on the two sides of the lower end surface of the oil circuit fixing plate, the hand-operated hydraulic pump is mounted at one end of the upper end surface of the oil circuit fixing plate, the hydrocylinders are connected with the hand-operated hydraulic pump through a hydraulic pipeline arranged in the oil circuit fixing plate, and the hydraulic lifting mechanism is used for unloading the oil pumping unit. The hydraulic unloading device greatly reduces the damage brought forth by the repeated use of a square clamp to a polish rod during unloading, so as to prolong the service life of the polish rod, lower the labor intensity of workers, shorten the operating time and guarantee the well opening time rate.
Description
Technical field
The utility model belongs to the auxiliary equipment that the petroleum industry producing well uses, and particularly a kind of oil pumper hydraulic load is plucked and unloaded device, is used to pluck unload oil pumper load, and the auxiliary test job of finishing the rod-pumped well indicator card and other are plucked the work of unloading oil pumper load.
Background technology
In the extraction process of crude oil, because the oil well indicator diagram measurement need uninstall rod-pumped well load repeatedly.Method commonly used is: shut down when bottom dead centre upwards moves about 30 centimetres, brake the side's of accomplishing fluently clamp at polished rod; Start oil pumper once more, shut down when polished rod runs near bottom dead centre, the inertia that utilizes polished rod to move downward is removed load.Install load transducer, hang up properly load, the side's of laying down clamp is frustrated burr, tests.After test finishes, when bottom dead centre upwards moves about 30 centimetres, shut down, brake the side's of accomplishing fluently clamp at polished rod; Start oil pumper once more, shut down when polished rod runs near bottom dead centre, the inertia that utilizes polished rod to move downward is removed load.Take out load transducer, hang up properly load, unload the below clamp, rub burr with the hands, open oil pumper.So each test all must be made two power clamps, and polished rod is caused big repeatability injury, has shortened the application life of polished rod.Can cause the polished rod premature failure when serious, cause oil well stopping production crude oil to leak, bring harmful effect to production, labor strength is big, and the operating time is long.
Summary of the invention
The purpose of this utility model provides a kind of oil pumper hydraulic load and plucks and unload device, makes it can guarantee that pumpingh well carries out test job, can effectively reduce the injury to polished rod again, reduces working strength of workers, thereby increases work efficiency.
Following technical proposals can reach its purpose: a kind of oil pumper hydraulic load is plucked and is unloaded device and comprise load support and hydraulic lifting mechanism, hydraulic lifting mechanism is placed on the below of load support.Hydraulic lifting mechanism comprises hydraulic jack, oil circuit fixed head and hydraulic hand-pump, hydraulic hand-pump is provided with relief valve, hydraulic jack is fixed on the both sides of oil circuit fixed head lower surface, hydraulic hand-pump is installed in a side of oil circuit fixed head upper surface, be connected by the hydraulic line that is provided with in the oil circuit fixed head between hydraulic jack and the hydraulic hand-pump, utilize hydraulic lifting mechanism to unload for oil pumper.
The utlity model has following advantage and effect: the injury when 1, the utility model reduces the side's of repeated use clamp to a great extent to polished rod unloading load, thus prolonged application life of polished rod.2, the utility model simplicity of design, cost of manufacture is low, and easy operating only at the first time of the side's of accomplishing fluently clamp during the installed load support, just need not repeat the side's of loading and unloading clamp later.Reduced working strength of workers, shortened the operating time, thereby increased work efficiency, rate when guaranteeing to drive a well.
Description of drawings
Accompanying drawing is an application state schematic diagram of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further detailed description: referring to accompanying drawing, a kind of oil pumper hydraulic load is plucked and is unloaded device and comprise load support 1 and hydraulic lifting mechanism, hydraulic lifting mechanism is placed on the below of load support 1.Load support 1 is provided with fagging and standpipe, and the mouth of pipe of standpipe is welded on the central authorities of fagging, and this standpipe is used to wear polished rod.Hydraulic lifting mechanism comprises hydraulic jack 6, oil circuit fixed head 2 and hydraulic hand-pump 3, and hydraulic hand-pump 3 is provided with relief valve 4, is used for controlling the oil circuit between hydraulic jack 6 and the hydraulic hand-pump 3.Hydraulic jack 6 is fixed on the both sides of oil circuit fixed head 2 lower surfaces, and hydraulic hand-pump 3 is installed in a side of oil circuit fixed head 2 upper surfaces, is connected by the hydraulic lines that are provided with in the oil circuit fixed head 2 between hydraulic jack 6 and the hydraulic hand-pump 3.The plate body middle part of oil circuit fixed head 2 is provided with U type slot, and this U type slot cooperates with the standpipe of load support 1, makes hydraulic lifting mechanism and load transducer 8 can be inserted into the fagging below of load support 1.
First-selected assembling hydraulic lifting mechanism by screwed connection, is installed in the both sides of oil circuit fixed head 2 lower surfaces with hydraulic jack 6 respectively, and the side in oil circuit fixed head 2 upper surfaces installs hydraulic hand-pump 3 by screwed connection.The side's of accomplishing fluently clamp 5 on the polished rod above the load support 1 passes polished rod with load support 1 after the shutdown, drops on the polished rod eye 7, just can be installed on the polished rod eye 7 always and need not to unload through after load support 1 is installed for the first time.Oil pumper is parked in lower dead point position, load transducer 8 is placed on the oil circuit fixed head 2 of hydraulic lifting mechanism, relief valve 4 is closed in the below of together inserting load support 1 fagging.Suppress by the handle of hydraulic hand-pump 3 then, the piston of hydraulic jack 6 is stretched out, oil pumper load is seated on the load transducer 8, test then drives a well.When test is finished, oil pumper is parked in the position of nearly bottom dead centre, rotate relief valve 4, hydraulic lifting mechanism of the present utility model and load transducer 8 together can be taken out, and load support 1 is stayed on the polished rod eye 7 so that use next time, and oil pumper load is afterwards plucked and also be need not the side's of re-using clamp 5 in the process of unloading.
