Abstract

An ejector for a crank pin of an oil pumping unit comprises a clamping seat (1), a center rod (2), a hollow jack (3), a high-pressure rubber hose (4) and a manual hydraulic pump (5). The ejector for the crank pin of the oil pumping unit is characterized in that the clamping seat (1) of the ejector for the crank pin of the oil pumping unit is of a channel steel shaped structure, the center rod (2) is arranged at the left center, the hollow jack (3) is sleeved on the center rod (2), and the hollow jack (3) is connected with the manual hydraulic pump (5) through the high-pressure rubber hose (4). The ejector for the crank pin of the oil pumping unit is simple in structure and safe to operate, the crank pin of the oil pumping unit can be quickly taken out, labor intensity of workers is reduced, operating efficiency is improved, oil well shutdown time is shortened, failed oil wells are less, and oil well yield is increased.

Description

The Crank Pin on Pumping Units backing-out punch
Technical field
the utility model relates to the beam type oil pumping machine crank pin and takes out tool technique, particularly is a kind of Crank Pin on Pumping Units backing-out punch.
Background technology
beam type oil pumping machine crank pin is as the main drive disk assembly of beam pumping unit quadric chain; Transfer ginseng, safeguarding, changing reduction box; During work such as commentaries on classics, last machine; Need frequent dismounting crank-pin, crank-pin dismounting efficient and installation quality have material impact to production.At present crank-pin being taken out needs two people's work high above the ground usually, pounds out in turn with sledge hammer, and labour intensity is big, dangerous high, easily the crank-pin screw thread is smashed, and the long sand well well of lying that is prone to cause consuming time, influence crude oil production.
Summary of the invention
The purpose of the utility model is exactly the technological deficiency to above-mentioned existence, designs a kind of Crank Pin on Pumping Units backing-out punch.
The purpose of the utility model is realized by following technical proposals:
the utility model comprises: deck, center-pole, hollow jack, high-pressure rubber pipe, hydraulic hand-pump.The deck of its Crank Pin on Pumping Units backing-out punch is channel-section steel shape structure, and center, the left side is provided with center-pole, and hollow jack is enclosed within on the center-pole, and high-pressure rubber pipe is connected hollow jack with hydraulic hand-pump.Hollow jack is selected commercially available RCH-603 type, bearing capacity 60T, stroke 89mm for use.
The beneficial effect of the utility model is: simple in structure, handling safety can be taken out Crank Pin on Pumping Units fast; Reduced worker's labour intensity, improved operating efficiency, shortened oil well and stop the well time; Reduce the oil well well of lying, increase oil well output.
Description of drawings
the utility model The field master TV structure sketch map.
In accompanying drawing, 1. deck, 2. center-pole, 3. hollow jack, 4. high-pressure rubber pipe, 5. hydraulic hand-pump, 6. decelerator, 7. crank-pin, 8. crank.
The specific embodiment
Below in conjunction with accompanying drawing further elaboration is done in the enforcement of the utility model:
the utility model is made up of deck 1, center-pole 2, hollow jack 3, high-pressure rubber pipe 4, hydraulic hand-pump 5.The deck 1 of its Crank Pin on Pumping Units backing-out punch is channel-section steel shape structure, and center, the left side is provided with center-pole 2, and hollow jack 3 is enclosed within on the center-pole 2, and high-pressure rubber pipe 4 is connected hollow jack 3 with hydraulic hand-pump 5.
Method of operating
at first are parked in the position base of crank-pin 7 facing to reduction box 6 with oil pumper, the outage of operating a switch, tension brake.Secondly, lay down the crown nut of crank-pin 7.The 3rd, be enclosed within hollow jack 3 on the center-pole 2, deck 1 is stuck on the base flange of reduction box 6, makes hollow jack 3 aim at crank-pin 7, connects high-pressure rubber pipe 4 two ends and hollow jack 3, hydraulic hand-pump 5.The 4th, close the relief valve of hydraulic hand-pump 5, the upper and lower handle that lifts hydraulic hand-pump 5 can eject crank-pin 7.
