The middle of the upper petal inner side of the polished rod sleeve locking casing is provided with a projected shaft, which is inserted into the relevant bolt groove at the inner side of the lower petal of the polished rod sleeve locking casing and is connected by a fixing pin. After involution, the bolt on the outer side of the polished rod sleeve locking casing lower petal is provided with the bolt groove on the outer side of the polished rod sleeve locking casing upper petal. The upper part of the disk root installing head is embedded into the lower middle part of the polished rod sleeve locking casing lower petal, and the parts of the screw are provided with a pair of handles symmetrically. The disk root is provided with rapid installation by the utility model.
Description
One, technical field
The utility model relates to a kind of used packing dress lifting device of rod-pumped well well head packing of changing.
Two, background technology
Changing at present the packing in the rod-pumped well well head packing box, all is outwards to rise singly or dress inwards with screwdriver, because of the packing box diameter smaller, when having adorned packing, just can't see packing at all, can not find packing inclined-plane tooled joint, pure is to become blind eyes outwards to choose packing or sabot root, change a packing and need more than 1 hour, and packing is not necessarily adorned flat, does not reach desirable sealing state, wastes time and energy, off-time is long, rate when influencing the production of oil well.
Three, summary of the invention
The purpose of this utility model provides a kind of packing dress lifting device, and overcoming above-mentioned replacing packing wastes time and energy, the defective that the off-time is long.
The technical solution of the utility model realizes in the following manner:
The utility model by polished rod cover, screw, polished rod cover locking cover, bolt, handle, screw, packing dress start, rotating shaft and bolt slot form, it is characterized in that the polished rod cover is made as two lobe formula cylinders, the polished rod cover locking portion of putting is made as two lobe formula cylinders, its underpart is a semicylinder, and the packing dress is started and is made as semicylinder; The vertical center that polished rod cover, polished rod cover locking cover and packing dress are started is provided with the semicircle orifice of polished rod; The lower end that polished rod overlaps a lobe is embedded in the hypovalve inner face upper end that the locking of polished rod cover is overlapped, be screwed together, the lower end of another lobe of polished rod cover is embedded in the epivalve inner face upper end of polished rod locking cover, be screwed together, the middle inside of the epivalve of polished rod cover locking cover is protruded a rotating shaft, being inserted in the polished rod cover locks in the bolt slot of the correspondence of overlapping the hypovalve inboard, connect by steady pin, two lobe symmetric involutions, involutory back cooperates fixing by the set bolt in the polished rod cover locking cover hypovalve outside with its corresponding set bolt slot in epivalve outside; The packing dress top of starting is embedded in the middle part, bottom of polished rod cover locking cover hypovalve, and is fixing together by screw, and be arranged with a pair of handle at screw with the upper part.
The packing dress top and the bottom semicolumn diameter of starting is big, and the middle part diameter is little, and top is arranged with screw hole, and half end of bottom semicolumn is made as the awl point, and second half end is flat mouthful or tiltedly flat mouthful.
The utility model top is involutory to be fastened on the polished rod, the packing dress is started and is inserted in the packing box, with the counter-rotating of handle to the packing angle, the packing angle can be started, once changeing a packing be tripped out again, forward rotate to the packing angle as the sabot root, the packing angle can be flattened, rotation just flattens packing again, and it is convenient, time saving and energy saving to have adorned packing, has improved the operating efficiency of changing packing.
Four, description of drawings
Accompanying drawing is a structural representation of the present utility model
1-polished rod cover 2-screw 3-polished rod cover locking cover 4-bolt 5-handle 6-screw 7-packing is adorned the 8-rotating shaft 9-bolt slot of starting among the figure
Five, the specific embodiment
For further disclosing the technical solution of the utility model, elaborate by embodiment below in conjunction with Figure of description:
The utility model by polished rod cover 1, screw 2, polished rod cover locking cover 3, bolt 4, handle 5, screw 6, packing dress start 7, rotating shaft 8 and bolt slot 9 form, it is characterized in that polished rod cover 1 is made as two lobe formula cylinders, polished rod cover locking cover 3 tops are made as two lobe formula cylinders, its underpart is a semicylinder, and packing dress is started and 7 is made as semicylinder; The vertical center that polished rod cover, polished rod cover locking cover 3 and packing dress are started is provided with the semicircle orifice of polished rod; The lower end that polished rod overlaps a lobe is embedded in the hypovalve inner face upper end that the locking of polished rod cover is overlapped, fix together with screw 2, the lower end of another lobe of polished rod cover is embedded in the epivalve inner face upper end of polished rod locking cover, fix together with screw 2, the middle inside of the epivalve of polished rod cover locking cover is protruded a rotating shaft 8, being inserted in the polished rod cover locks in the bolt slot of the correspondence of overlapping the hypovalve inboard, connect by steady pin, two lobe symmetric involutions, involutory back cooperates fixing by the set bolt 4 in the polished rod cover locking cover hypovalve outside with the corresponding set bolt slot 9 in its epivalve outside; The packing dress top of starting is embedded in the middle part, bottom of polished rod cover locking cover hypovalve, and is fixing together by screw, and be arranged with a pair of handle 5 at screw with the upper part.
When using the utility model, the utility model top is involutory to be fastened on the polished rod, the packing dress is started and is inserted in the packing box, with the counter-rotating of handle to the packing angle, the packing angle can be started, once changeing a packing is tripped out again, forward rotate to the packing angle as the sabot root, the packing angle can be flattened, rotation just flattens packing again, it is convenient, time saving and energy saving to have adorned packing, has improved the operating efficiency of changing packing.
