Abstract
The utility model discloses an auxiliary tool for changing packing of an oil pumping machine well head, which comprises a hook head (1), a fixing rubber gasket (2), a movable rubber gasket (3), a lock block (4), a screw sleeve (5), a 'T-shaped' screw rod (6), an ejector rod (7), a handle sleeve (8) and a handle (9). The fixing rubber gasket (2) is arranged inside the hook head (1); the other end of the hook head (1) is in screwed connection with the ejector rod (7); a screwed hole is arranged at the front end of the ejector rod (7); the 'T-shaped' screw rod (6) is in movable connection with the arc-shaped lock block (4) provided with the movable rubber gasket (3) through the screw sleeve (5); the 'T-shaped' screw rod (6) is in screwed connection with the ejector rod (7); the handle sleeve (8) is arranged at the rear end of the ejector rod (7); and the handle (9) is movably matched with the handle sleeve (8), and a square hole (10) is arranged in the middle of the handle (9). When the packing is changed in an oil pumping machine well, a press cap and a press cover of a fixed polish rod sealer are firm as well as safe and reliable; the auxiliary tool is convenient to use; therefore, the working efficiency and the production time rate of the oil well are improved; and the yield of crude oil is increased.
Description
Technical field
The utility model relates to a kind of replacing oil pumper well head packing aid.
Background technology
At present oilfield pumping well in process of production, the replacing of well head packing is regular work, when changing packing; Must horse head be parked near bottom dead centre; With hook or rope pressure cap and gland are hung bolt on polished rod eye, not firm because of hanging bolt, the frequent accident that injures operating personnel's hand by a crashing object; In addition, because operating personnel's qualification is different, often need shuts down and could horse head be parked in correct position for several times during shutdown, waste time and energy, influence crude oil production.
Summary of the invention
The purpose of the utility model is exactly the above-mentioned defective that exists to prior art, and a kind of replacing oil pumper well head packing aid is provided.
The utility model technical scheme comprises: eave tile, fixedly rubber blanket, active rubber pad, lock dog, silk braid, T-shape screw rod, push rod, grip, handle.Its inside of changing the eave tile of oil pumper well head packing aid is provided with fixedly rubber blanket; The eave tile other end and push rod thread connection, the push rod front end is provided with screwed hole, and silk braid is the T-shape screw rod and have movable connection of arc lock dog of active rubber pad; T-shape screw rod and push rod thread connection; The rear end of push rod is provided with grip, and the handle that the centre has square hole cooperates with grip is movable, takes off handle and can be used to switch rubber gate.
The beneficial effect of the utility model is: when rod-pumped well was changed packing, horse head can be parked in the optional position, and fixedly polished rod sealer pressure cap and gland are firm, and be safe and reliable, easy to use, and rate when increasing work efficiency with oil well production increases crude output.
Description of drawings
Accompanying drawing is that the utility model master looks the broken section structural representation.
In the accompanying drawing, 1. eave tile, 2. fixing rubber blanket, 3. active rubber pad, 4. lock dog, 5. silk braid, 6. T-shape screw rod, 7. push rod, 8. grip, 9. handle, 10. square hole, 11. polished rods.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is done further to describe:
Shown in accompanying drawing, change oil pumper well head packing aid by eave tile 1, fixedly rubber blanket 2, active rubber pad 3, lock dog 4, silk braid 5, T-shape screw rod (6), push rod 7, grip 8, handle 9 are formed.Fixedly rubber blanket 2 is posted in its inside of changing the eave tile 1 of oil pumper well head packing aid; Eave tile 1 other end and push rod 7 thread connection; Push rod 7 front ends are provided with screwed hole; Silk braid 5 is T-shape screw rod 6 and 4 movable connections of the arc lock dog that posts active rubber pad 3, and T-shape screw rod and 6 push rods, 7 thread connection penetrate the middle handle 9 that has square hole 10 in the rear end grip 8 of push rod 7.Eave tile 1 blocks polished rod 11 during use, clockwise rotates handle 9, and push rod 7 drives lock dog 4 polished rod 11 is held out against.Take off handle 9, square hole 10 blocks the valve rod square toes of rubber gate, can carry out switching manipulation.
