With reference to accompanying drawing 1-3, show in accordance with the principles of the present invention for the decomposing schematic representation of dismounting threaded connector, the in particular instrument of the threaded connector of large-scale petroleum instrument and equipment.Instrument 100 comprises cylindrical-shaped main body 2, spring 3, rotatable spanner 6 and block piece 5.One end of main body 2 is circumferentially provided with projection 21 and hole 22, preferably, be provided with multiple projection and multiple hole, and more preferably described hole circumferentially separates equally spacedly.As it will be appreciated by one of skill in the art that, advantageously, at least 3 holes are set, exemplarily, such as 6,8,9,12 (figure 1 illustrates 12 projections and 12 holes, and circumferentially alternately arrange), to enable bolt 1 main body 2 be firmly fixed relative to threaded connector (not shown) through described hole.In particular, bolt 1 can through pleasure boat hole corresponding on several in this some holes and threaded connector to be fixed relative to threaded connector by dismantling device, thus prevent dismantling device from sliding.
Rotatable spanner 6 has shank 61 and circular end 62, the side of shank 61 is provided with two locating pieces 611, and described circular end 62 can be held in main body 2 outer surface on rotate around its axis.As shown in Figure 1-2, the outer surface of the other end contrary with arranging porose one end of main body 2 is provided with helicitic texture, the circular end 62 of rotatable spanner 6 can be held on the outer surface of main body 2 by the retainer ring 7 like this by being spirally connected with this helicitic texture.Certainly it will be readily apparent to those skilled in the art that also by other fit structures, the circular end 62 of rotatable spanner 6 can be held in main body 2 outer surface on rotate around its axis.
Block piece 5 has bar portion 51 and tongue end 52, its king-rod portion 51 can be passed in the hole 612 of setting in the locating piece 611 on rotatable spanner 6 and make suit spring 3 thereon between locating piece 611, and in order to be made the projection 21 of tongue end 52 against main body 2 of block piece 5 in instrument use by the spring force of spring 3, one end of spring 3 and block piece 5 are fixed and the other end and rotatable spanner 6 are fixed.Advantageously, the size of the bar portion 51 of block piece 5 near the side of described tongue end 52 can be made larger than the size of its opposite side, exemplarily, the bar portion 51 of block piece 5 diametrically can be tapered towards opposite side near the side of described tongue end, the described side place that one end of such spring 3 can be held in the close tongue end 52 in bar portion 51 is fixed, and the other end of spring 3 can be fixed away from the locating piece 611 of circular end 62 on rotatable spanner 6.
With reference now to Fig. 4-6, show the assembly 200 that can combinationally use with the dismantling device of Fig. 1.Assembly 200 comprises header board 9 and rear plate 11, and described header board 9 and rear plate 11 can clamping be treated by the threaded connector of dismounting by bolt 8 being screwed into the hole 92,111 that is arranged on header board 9 and rear plate 11.In addition, in order to increase the clamping force of clamping when the threaded connector by dismounting, it is as visible in detail in Fig. 6 that the inner surface of header board 9 and rear plate 11 all has protruding 30().In addition, in order to can fixedly treat by the threaded connector of dismounting in case it skids in disassembly process further, the central authorities of header board 9 be provided with positioning threads through hole 91, to be fixed relative to threaded connector by header board by positioning threads pin 10.
Principle of the present invention will be described below.
When carrying out disassemble and assemble work, the main body 2 of dismantling device 100 is sleeved on the correct position of the side of threaded connector to be disassembled, and when being multiple through the hole 22(in main body 2 in hole by bolt 1, can only use wherein several, preferably equally spaced 3) so that dismantling device 100 is fixed relative to threaded connector (not shown).Then, the bar portion 51 of block piece 5 be passed in the hole 612 that arranges in the locating piece on rotatable spanner 6 and make suit spring 3 thereon between locating piece 611, then using retainer ring 7 to be held on the outer surface of main body 2 the circular end 62 of rotatable spanner 6.So just dismantling device is fitted together, as shown in Figure 3.
When needed, by the header board 9 in the assembly of Fig. 2 and the rear plate 11 chuck opposite side at threaded connector (not shown) to be disassembled, and can be treated by the threaded connector of dismounting by bolt 8 clamping.As will also be appreciated by those of skill in the art, bolt 8 can adjust the distance between header board 9 and rear plate 11, thus adapts to threaded connector to be disassembled better, as shown in Figure 4.
After fixing dismantling device (when using combination tool, this combination tool can be fixed by fixture such as bench vice and preventing it from sliding), pull the shank 61 of rotatable spanner 6, just can dismantle or threaded connector is installed.
Preferably, the front-end surface of the tongue end 52 of block piece 5 is that scarf 520(is as visible in detail in Fig. 3), like this can by the rotation direction of the rotatable spanner 6 of free adjustment towards (i.e. scarf 520 towards) of adjustment tongue end 52.
In addition, it is obvious to the person skilled in the art that by utilizing hydraulic transmission fix the shank 61 of rotatable spanner 6 and rotate, thus the larger applicability of dismantling device is realized.
Although describe at least one one exemplary embodiment in the detailed description above, be understood that to there is a large amount of distortion.Be to be further appreciated that an one exemplary embodiment described here or multiple one exemplary embodiment are only examples, be not intended to limit the scope of the invention by any way, applicability or structure.On the contrary, detailed description above by the guide of providing convenience for those skilled in the art to implement an one exemplary embodiment or multiple one exemplary embodiment.Be to be understood that and can make a variety of changes the function of element and arrangement when not departing from the scope of the invention illustrated by claims and legal equivalent thereof.
