Abstract
The utility model provides a tool for disassembling and assembling a top drive power accumulator, which consists of a disc main body, a plurality of holes, a stabilizing pin and a lug boss, wherein the center of the disc main body is a square lug boss, the periphery of the disc main body is provided with the holes with different sizes, and the sizes of the holes and the stabilizing pin can be adapted to that of the power accumulator, and the stabilizing pin is in clearance fit with the holes. The tool can combine three parts into a whole body, and is time-saving and labor-saving, very convenient for disassembling and assembling, simple in structure, practical, economic, and easy to machine and manufacture.
Description
Technical field
The utility model relates to a kind of specific purpose tool, especially a kind of specific purpose tool that can drive three kinds of accumulators of dismounting on oil drilling device VARCO top.
Background technology
At present, it is that three kinds of accumulators respectively have a dismantling device that the accumulator dismantling device is driven on well-known top, has three kinds, and shape differs, and the stable pin on the instrument is in use, easy deformation, thus do not reach good effect, not only time-consuming but also require great effort.In the oil drilling industry, drilling team moves about, and number of packages is many deposits and take up room, and loses easily.
Summary of the invention
The purpose of this utility model is to overcome two big shortcomings of existing accumulator dismantling device, a kind of use is provided and deposits all very easily the top and drive the accumulator dismantling device; Stable pin on the instrument can arbitrarily be changed and material changes into and is high-speed steel, is not easy distortion.Effectively the accumulator that drives is pushed up in maintenance and repair, reduces cost of equipment maintenance.
The technical scheme that the utility model adopted is: the accumulator dismantling device is driven on the top, is made up of disc body, hole, stable pin, boss, and the central authorities of disc body are square boss, are distributed with the hole of different size all around.The size and the accumulator of hole and stable pin adapt; Stable pin is a matched in clearance with the hole.
The beneficial effects of the utility model are, can three unifications, save time, laborsaving, and carry out dismounting very easily, simple in structure, practical, economic, processing and manufacturing easily.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a generalized section of the present utility model.
1 is big stable pin among the figure, and 2 is little stable pin, and 3 is boss, and 4 is disc body.
The specific embodiment
As shown in the figure: the accumulator dismantling device is driven on the top, is made up of disc body 4, hole, big stable pin 1, little stable pin 2 and boss 3, and the central authorities of disc body 4 are square boss 3, are distributed with the hole of different size all around.The size and the accumulator of hole and big stable pin 1 and little stable pin 2 adapt; Big stable pin 1 and little stable pin 2 are matched in clearance with corresponding hole.
Three accumulators that drive on VARCO top: hydraulic system accumulator, balance accumulator, the IBOP accumulator of delay time, when needing to change sealing, must dismantle the big plug at accumulator two respectively, could take out the piston in the cylinder, replacing seals.When disassembling system accumulator and balance accumulator, the stable pin that uses is that three sizes all sell 1 as the big stable of Φ 11.2mm, and the stable pin that the IBOP accumulator uses is the little stable pin 2 that two sizes all are Φ 4.8mm, and during the big plug at dismounting two, trustworthy rationed marketing is inserted in the hole on the big plug of accumulator, put instrument, also be inserted in the hole corresponding on the instrument, utilize monkey wrench, be stuck on the cubic boss 3 of tool body, rotation counterclockwise, the big plug of will dismantling very easily.During assembling, to clockwise direction rotation, till reaching certain spinner moment of torsion.
Utilize the disc body 4 of the disk of a steel as instrument, according to the different size in dismounting hole on three kinds of accumulators, stamp different corresponding three kinds of holes on disk, the stable pin of processing different size gets final product.When these three accumulators of dismounting, can use this instrument, just change stable pin and corresponding hole, convenient and labor-saving, reach save time, the labour-saving purpose.
Before use, check earlier whether stable greatly pin 1 or little stable pin 2 are out of shape, if the stable pin of improper just replacing, the hole on the anti-instrument here is also distortion under stressed situation.
In use, the hole correspondence on instrument and the accumulator is coincide,, note firmly wanting evenly to avoid swinging, take care with hand steered firmly this instrument with big stable pin 1 or little stable pin 2.
Claims (3)
1. the accumulator dismantling device is driven on the top, is made up of disc body, hole, stable pin, boss, and the central authorities that it is characterized in that disc body are square boss, are distributed with the hole of different size all around.
2. the accumulator dismantling device is driven on top according to claim 1, it is characterized in that the size and the accumulator of hole and stable pin adapts.
3. the accumulator dismantling device is driven on top according to claim 1, it is characterized in that stable pin is a matched in clearance with the hole.
