Abstract
The utility model relates to a special tool for adding and replacing packing, which is used for fixing a packing box pressure cap when the packing is replaced in an oil field. The special tool for adding and replacing the packing mainly consists of a handle, a screw rod and a U-shaped pipe. The U-shaped pipe is of a cylinder shape and is provided with a center hole. The wall of the U-shaped pipe is provided with an axial notch. Both lateral surfaces of the axial notch are parallel. The width of the axial notch is equal to the diameter of the center hole, i.e. a polished rod can enter the center hole. The wall of the U-shaped pipe is provided with a screw hole. The center line of the screw hole is vertical to the center line of the U-shaped pipe and simultaneously the center line of the screw hole is vertical to the lateral surfaces of the notch of the U-shaped pipe. The screw rod is arranged in the screw hole of the U-shaped pipe. The handle is welded at the outer end of the screw rod. The special tool for adding and replacing the packing has the effects that the packing box pressure cap can be fixed on the polished rod of an oil pumping unit, so that the packing box pressure cap cannot fall down and hands of an operator are prevented from being injured by the packing box pressure cap; the working intensity of the operator is reduced; the working efficiency is improved; the special tool is convenient to operate; and the time is saved.
Description
Technical field
The utility model relates to oil recovery technique field, oil field, particularly a kind ofly prevents the operative employee when changing packing, and fixedly the special tool of packing lid is a kind of dedicated fixed device of fixedly packing box.
Background technology
Add on pumpingh well that to change packing operation be one of the general and the most frequent work in the normal work on work day of recovering the oil.Because the restriction of thick oil horizontal well and straight well space and condition in adding the packing operating process very easily causes and squeezes the generation of hindering hand and injuring well head operation injury accidents such as hand by a crashing object.At present, add when changing the packing operation, adopt iron wire to lash the packing box pressure cap more.Take off when iron wire is disconnected suddenly, cause the landing of packing box pressure cap, cause to injure operating personnel's hand incident by a crashing object.
The utility model content
The purpose of this utility model is: a kind of special tool that changes packing that adds is provided, can be on oil-extractor polish-rod fixing packing box pressing cap, the packing box pressure cap can not be fallen, prevent that the packing box pressure cap from injuring operating personnel's hand by a crashing object.
The technical solution adopted in the utility model is: add the special tool that changes packing, mainly form by handle, screw mandrel and U-shaped pipe, it is characterized in that: the U-shaped pipe is the cylinder bodily form and centre bore is arranged, axial gap is arranged on the wall of U-shaped pipe, axially the two sides of gap are parallel to each other, axially the width of gap is identical with the diameter of centre bore, and promptly polished rod can enter in the centre bore; On the wall of U-shaped pipe screw is arranged, center line of bolt hole is vertical with the center line of U-shaped pipe, and the center line of screw is vertical mutually with the gap side of U-shaped pipe simultaneously; A screw mandrel is arranged in the screw of U-shaped pipe; Outer end at screw mandrel is welded with handle.In polished rod entered the centre bore of U-shaped pipe, by rotating handles, the inner of screw mandrel compressed the polished rod outer wall, and the U-shaped pipe is securely fixed on the polished rod.U-shaped pipe upper support packing box pressing cap.The packing box pressure cap can not landing, thoroughly solves the accident that the packing box pressure cap injures maintenance mans' staff by a crashing object.
In order to make the U-shaped pipe can support the packing box pressing cap better, the upper end diameter of described U-shaped pipe is greater than lower end diameter.
The beneficial effects of the utility model: the utility model adds the special tool that changes packing, can be on oil-extractor polish-rod fixing packing box pressing cap, the packing box pressure cap can not be fallen, prevent that the packing box pressure cap from injuring operating personnel's hand by a crashing object.Reduce employee's working strength, increase work efficiency, and easy to operate, also saved the time.
Description of drawings
Fig. 1 is that the utility model adds the special tool structural profile schematic diagram that changes packing.
Fig. 2 is the vertical view of Fig. 1.
Among the figure, 1-handle, 2-screw mandrel, 3-U shape pipe.
The specific embodiment
Embodiment 1: adding the special tool that changes packing with one is example, and the utility model is described in further detail.
Consult Fig. 2.The utility model adds the special tool that changes packing, mainly is made up of handle 1, screw mandrel 2 and U-shaped pipe 3.U-shaped pipe 3 is the cylinder bodily form, the lower end external diameter 50mm of U-shaped pipe 3, and upper end external diameter 70mm, overall height is 50mm.It is the centre bore of 30mm that U-shaped pipe 3 has diameter, and an axial gap is arranged on the wall of U-shaped pipe 3, and axially the two sides of gap are parallel to each other, and axially the width of gap is identical with the diameter of centre bore, and promptly polished rod can enter in the centre bore, and the diameter of polished rod is 29mm.The screw of a M14 is arranged on the wall of U-shaped pipe 3, and center line of bolt hole is vertical with the center line of U-shaped pipe 3, and the center line of screw is vertical mutually with the gap side of U-shaped pipe 3 simultaneously.The screw mandrel 2 that a M14 is arranged in the screw of U-shaped pipe 3; The length of screw mandrel 2 is 60mm.Be welded with cylinder bodily form handle 1 in the outer end of screw mandrel 2.
