Abstract
The utility model discloses a pumping unit well mouth packing adding and extracting device. The adding and extracting device comprises a fixed clamp, a rotary adder and a spiral line extractor, wherein the fixed clamp is of a double-half-part structure with a disk-shaped groove in the middle; the rotary adder is also of a double-half-part structure and is provided with a disk-shaped bulge at the upper part; a limit groove is formed in the middle of the rotary adder; the disk-shaped bulge is located inside the disk-shaped groove of the fixed clamp; the rotary adder can rotate freely relative to the fixed clamp; a spiral line groove is formed below the rotary adder; the spiral line extractor is arranged in the spiral line groove of the rotary adder in advance; an external connection handle of the spiral line extractor penetrates through the spiral line groove to be fixed together with the spiral line extractor. The adding and extracting device is simple in structure, convenient to use, and capable of extracting a worn packing of a pumping unit and other sealing fillers out a packing box and then adding a new packing and other sealing fillers into the packing box at one step; the adding and extracting device can be used for saving time and labor and can accomplish the operation without being matched with other tools; besides, the safety risk during operation is lowered and the work efficiency is enhanced.
Description
Technical field
The utility model is the instrument that a kind of work of recovering the oil is used for adding, extracting the interior packing pad of oil pumping machine well head packing box and other airtight and watertight padding.
Background technology
Packing is to be installed in oil pumping machine well head packing kit of rubber valve and the packing material of the annular space of polished rod fitted seal packing box and polished rod, and material mostly is quality of rubber materials.Its effect is in the reciprocating process of polished rod, to stop oil, gas, water, prevents excessive.Between polished rod and packing, acutely, packing loss is large in friction.When changing and adding packing filling, because the external diameter of seal request additive will suitably be greater than be added device bore, therefore operation easier strengthens when adding packing.It is all to adopt hammer to strike that well head packing pad was installed in the past, the mode on screwdriver top, and labour intensity is larger, sometimes operating personnel, well head screw thread, polished rod is had to damage in various degree.
Summary of the invention
The purpose of this utility model is to provide a kind of interpolation and extraction element of beam-pumping unit portal disc radical, the utility model packing and other airtight and watertight padding simple in structure, easy to use, that oil pumper can be worn propose from packing box, then can new packing and other airtight and watertight padding be once added in packing box, the utility model is time saving and energy saving, do not need other instrument to coordinate and can complete this operation, reduce handling safety risk, improved operating efficiency.
The utility model is by fixation clamp, rotation adder, helix extractor and Special force application wrench form, fixation clamp is two half hitches structure, centre has plate-like groove, rotation adder is also two half hitches structure, the top of rotation adder is plate-like projection, the middle part of rotation adder is stopper slot, this plate-like projection is arranged in the plate-like groove of fixation clamp, rotation adder can freely rotate relative to fixation clamp, the below of rotation adder is provided with helix groove, helix extractor is arranged in the helix groove of rotation adder in advance, the external handle of helix extractor sees through helix groove and helix extractor is fixed together, the end of helix extractor has the incision cutter head of 40 ° of rake angles.
The beneficial effects of the utility model:
The utility model packing and other airtight and watertight padding simple in structure, easy to use, that oil pumper can be worn propose from packing box, then can new packing and other airtight and watertight padding be once added in packing box, the utility model is time saving and energy saving, do not need other instrument to coordinate and can complete this operation, reduce handling safety risk, improved operating efficiency.

The specific embodiment
Refer to shown in Fig. 1 to Fig. 7, the present embodiment is by fixation clamp 1, rotation adder 2, helix extractor 3 and Special force application wrench 4 form, fixation clamp 1 is two half hitches structure, centre has plate-like groove 11, rotation adder 2 is also two half hitches structure, the top of rotation adder 2 is plate-like projection 21, the middle part of rotation adder 2 is stopper slot 23, this plate-like projection 21 is arranged in the plate-like groove 11 of fixation clamp 1, rotation adder 2 can freely rotate relative to fixation clamp 1, the below of rotation adder 2 is provided with helix groove 22, helix extractor 3 is arranged in the helix groove 22 of rotation adder 2 in advance, the external handle 31 of helix extractor 3 sees through helix groove 22 and is fixed together with helix extractor 3, the end of helix extractor 3 has the incision cutter head 32 of 40 ° of rake angles.
The course of work of the present utility model:
Packing pressure cap and Glan are suspended on polished rod eye A, 2 pairs of adders of rotation are stuck on the polished rod B of packing box C top, fixation clamp 1 is fixed on polished rod B, the plate-like projection 21 of rotating adder 2 is combined with the plate-like groove 11 of fixation clamp 1, making to rotate adder 2 can rotate freely in fixation clamp 1 plate-like groove 11, helix extractor 3 is arranged in the helix groove 22 of rotation adder 2 in advance, when external handle 31 is subject to downward active force, helix extractor 3 is made rotating screw line around polished rod B downwards along rotation adder 2 helix grooves 22 and is moved.Because packing is done the otch of 30 ° to 45 ° before interpolation, therefore helix extractor 3 ends are the incision cutter head 32 of 40 ° of rake angles, during the line of spinning to bottom right at helix extractor 3 motion, the incision cutter head 32 of 40 ° is pressed in the incision of packing D, while continuing to move downward, packing D and other filler screw out to opposite direction helix with helix extractor 3.After all fillers are got only, new packing D filler is cut after 30 ° to 15 ° otch clockwise, 45 ° of bottom angles along rotation adder 2 are put into, use Special force application wrench 4 to be stuck in the stopper slot 23 of rotation adder 2, to anticlockwise, disposable packing D is pressed in packing box C, during a plurality of new packing D stack, to place in the 120 °Zhi180° positions of staggering, be rotated and be pressed into successively, realize the work that packing D adds, until fill up packing box C.Take off fixation clamp 1 and rotation adder 2, Glan and packing pressure cap are installed.
