Specific embodiment
Unless otherwise defined, all technical terms used in the embodiment of the present invention all have usual with those skilled in the art
The identical meaning understood.To make the object, technical solutions and advantages of the present invention clearer, below in conjunction with attached drawing to this hair
Bright embodiment is described in further detail.
The embodiment of the invention provides a kind of apparatus for assembling packings, and as shown in attached drawing 1 and attached drawing 2, which includes: righting branch
Frame 1；Adjusting rod 2, level are adjustably fixed on the upper end of straightening support 1；Righting part 3 is connect with the free end of adjusting rod 2,
For offseting with polished rod；Clamping cylinder 4 is connect with the lower part of straightening support 1, as shown in Fig. 3, is provided on the wall of clamping cylinder 4
Open slot 401 for passing through polished rod, clamping cylinder 4 are sleeved on packing box for being rotatably fixed；First compressing member 5,
It is arranged on the inner wall of clamping cylinder 4, for compressing packing downwards.
The working principle with regard to apparatus for assembling packings provided in an embodiment of the present invention, which is given, below describes:
Before the application device, need by the pressure cap disassembly on packing box, to expose old packing.Old packing can make
After the device, is taken out, can also be taken out before using the device by tools such as hooks.
When using the device, it adjusts the horizontal position of adjusting rod 2 first to change the position of righting part 3, and then avoids shadow
Ring the installation of clamping cylinder 4.Then so that polished rod is passed through the open slot 401 on clamping cylinder 4, and be sleeved on clamping cylinder 4 on packing box
Portion.The skew direction of well mouth of oil well is observed, then rotating clamping cylinder 4 to adjust the direction of righting part 3 makes righting part 3 and polished rod
It offsets, and by the axial location on polished rod top to packing box, so that polished rod is concentric with packing box.By multiple packings with cutting mouth
It is put into the annular space of polished rod and packing box by the open slot 401 of clamping cylinder 4, is rotated down clamping cylinder 4, until clamping cylinder 4
Until cannot continuing to move down.In the process, the first compressing member 5 on 4 inner wall of clamping cylinder is set around the axis of polished rod
Line rotation, with uniform compaction packing.Further, cylinder 4 is rotatably compressed upwards, so that clamping cylinder 4 is detached from packing, is finally unloaded whole
A device is completed to add packing operation.
Apparatus for assembling packings provided in an embodiment of the present invention, by the way that open slot 401 is arranged on clamping cylinder 4, convenient for making polished rod
It penetrates or is pierced by, and then be sleeved on packing box convenient for clamping cylinder 4.It is compressed by the way that first is arranged on the inner wall of clamping cylinder 4
Part 5, convenient for driving the first compressing member 5 to rotate and being equably compacted packing when rotatably compressing cylinder 4.By the way that righting branch is arranged
Frame 1, adjusting rod 2, righting part 3 are convenient for by polished rod righting, to facilitate addition packing.As it can be seen that device provided in an embodiment of the present invention
Structure it is simple, be convenient for one man operation, can be by multiple packing uniform compactions, and improve plus the working efficiency of packing.
Specifically, the mode that clamping cylinder 4 can be connected through a screw thread is fixedly set on packing box, can also pass through friction
Power is fixedly set on packing box.In addition to this, clamping cylinder 4 can also be fixedly set on packing box by way of clamping.
Wherein, axially disposed on the inner wall of clamping cylinder 4 to have a groove, it is axially disposed on the outer wall of packing box to have multiple and groove
The height on packing box of clamping cylinder 4 may be implemented by the way that shackle member to be caught in different grooves in compatible shackle member
Adjustment and the fixation of clamping cylinder 4 and packing box.
Packing is uniformly compressed for the ease of the first compressing member 5, and does not scratch packing, as shown in Fig. 1, the first compressing member 5
