Abstract
The utility model discloses a safety polished rod clip for a pumping unit well. The clip comprises a main body, a baffle plate, a fixing bolt and slips; and the main body 1 of the clip is a ''cros'' body formed by cutting a cuboid, the middle is provided with a tapered hole which is matched with three slips, the slips are preferably exposed for 8 to 10 millimeters, the middle is provided with an opening communicated with the tapered hole, a baffle plate groove is formed in the direction vertical to the opening, and the baffle plate is inserted into the baffle plate groove and fixed by the fixing bolt. The clip is used for clipping a polished rod to bear the underground load, has simple structure, low cost and safe operation, is convenient to process and use, saves time, and improves the oil recovery efficiency.
Description
One, technical field
The utility model relates to oil field beam pumping unit well auxiliary accessories, particularly is a kind of rod-pumped well safety polished rod clamp.
Two, background technology
Oil pumper is the capital equipment of crude oil production, drive a well all at every turn will on carry dead space, oil pumper is to be connected by the tight polished rod of polish rod clamp subcard on the polished rod eye with sucker rod, oil well pump connector.Because the polished rod clamp that uses is made up of two card body two bolts and slips sheet at present, the phenomenon of strip polished rod clamp in use often occurs, its reason mainly is that operating personnel exert oneself not enough and misoperation causes.Particularly some woman's strength is little, and is the operation of ascending a height, and does not use power when fastening bolt, causes strip polished rod clamp phenomenon to take place, and has influenced the ordinary production of rod-pumped well.
Three, summary of the invention
The purpose of this utility model is exactly the above-mentioned defective that exists at prior art, a kind of rod-pumped well safety polished rod clamp of designing.
The utility model comprises: main body, baffle plate, set bolt, slips; " ten " font body that its main body 1 is formed by the cuboid cutting, the centre is a tapered hole, cooperates with three lobe slips, slips 8～the 10mm that leaks outside is advisable, and is provided with the opening that communicates with tapered hole in the centre, is provided with baffle plate groove on perpendicular to opening direction, baffle plate inserts in the baffle plate groove, is fixed by set bolt.
The beneficial effects of the utility model are: be used for blocking polished rod and bear down-hole load, simple in structure, easy to process, with low cost, easy to use, handling safety is saved time, and improves rate when recovering the oil.
Four, description of drawings
Fig. 1-the utility model axle geodesic structure schematic diagram.
Fig. 2-the utility model The field schematic diagram.
In the accompanying drawing, 1. main body, 2. baffle plate, 3. set bolt, 4. slips, 5. mao plait, 6 polished rods, 7. rod-pumped well safety polished rod clamp 8. coils on the polished rod eye, 9. testing arrangement, 10. polished rod eye lower wall; A. opening, the b. baffle plate groove.
Five, the specific embodiment
Below in conjunction with accompanying drawing enforcement of the present utility model is further elaborated:
Rod-pumped well safety polished rod clamp comprises: main body 1, baffle plate 2, set bolt 3, slips 4; " ten " font body that its main body 1 is formed by the cuboid cutting, the centre is a tapered hole, cooperate with three lobe slips 4, the slips 4 8～10mm that leaks outside, be provided with the opening a that communicates with tapered hole in the centre, be provided with baffle plate groove b on perpendicular to opening a direction, baffle plate 2 inserts in the baffle plate groove b, and is fixing by set bolt 3.
Method of operating:
At first, oil pumper is parked near the lower dead point position tight brake of stopping, and cuts off the electricity supply.Secondly, rod-pumped well safety polished rod clamp 7 is stuck in well head and lays down the oil pumper load.The 3rd, the set bolt 3 of the simple and easy polished rod clamp 7 of rod-pumped well is unloaded pine, open baffle plate 2, making the simple and easy polished rod clamp 7 opening a of rod-pumped well block polished rod 6 is positioned on the polished rod eye on the dish 8, put down baffle plate, tighten set bolt 3, slips 4 is put into main body 1 middle coniform hole, with adze-eye hammer slips 4 is evenly pounded tightly then.The 4th, releasing of brake is laid down the rod-pumped well safety polished rod clamp 7 on the well head, closes a floodgate and send electricity, starts oil pumper, end of operation.
