Label in figure is expressed as: 1, outer-hexagonal joint; 2, blind hole; 3, screwed hole; 4, cylinder body; 5, interior hexagonal jack; 6, collecting tank; 7, infusion hole; 8, pilot hole.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is further illustrated.
Embodiment 1
The erecting tools for valve rod locking nut location as shown in Figure 1 and Figure 2, comprise cylinder body 4, cylinder body 4 two ends arrange respectively interior hexagonal jack 5 and outer-hexagonal joint 1, described cylinder body 4 middle parts set gradually collecting tank 6, infusion hole 7 and the pilot hole 8 of connection vertically, described collecting tank 6 is positioned at the end of outer-hexagonal joint 1 place end, and the described collecting tank 6 tapered structures in cross section, described pilot hole 8 is communicated with interior hexagonal jack 5, and the diameter of described pilot hole 8 is greater than the diameter of infusion hole 7.
When the present embodiment is used, locking nut is screwed in to part in advance to valve rod, then by interior hexagonal jack 5, coordinate with locking nut, hand-held cylinder body 4 rotary cylinder main bodys 4, by cylinder body 4, rotate and drive locking nut to rotate, thereby by locking nut precession, pilot hole 8 is for guiding valve rod and pilot hole 8 length identical with valve rod position length, when precession, valve rod upper end clamps by pilot hole 8 upper ends, thereby reach the position location of locking nut, after setscrew nut is had good positioning, instrument is taken out; When taking out setscrew nut, also can adopt this instrument; The present embodiment is socketed handwheel on hex union 1 outside when precession nut, and staff can hold hand wheel rotating cylinder body 4, time saving and energy saving, and handwheel can arbitrarily take off, and does not take up space; When precession locking nut, as occurred the situations such as precession difficulty, jam, can in collecting tank 6, add lubricating fluid, lubricating fluid flows into valve rod and locking nut contact-making surface by infusion hole 7 and pilot hole 8, plays lubrication, reduces nut precession difficulty.
The present embodiment passes through said structure; can carry out very easily the handling of locking nut, and position location that can positioning and locking nut by pilot hole 8, locking nut rigging error is less; and hex union 1 inner sleeve enters handwheel outside when rotating cylindrical main body 4; reduce precession time and difficulty, and also can add lubricating fluid to be lubricated valve rod and locking nut, reduced precession resistance; not only protected threaded stem; and can improve nut precession speed, safety, efficient, practical.
Embodiment 2
Embodiment has increased following structure on the basis of embodiment 1, is specially: described cylinder body 4 is positioned at the outer circumference face diameter of infusion hole 7 to being provided with two symmetrically arranged blind holes 2.
In the present embodiment blind hole 2, can insert threaded straight-bar, with handwheel drive torque compared with large and when precession is slow or nut resistance is larger, staff can hold two straight-bars in blind hole 2, carrys out rotary cylinder main body 4 by straight-bar, can reduce positioning difficulty, save manpower.
Embodiment 3
The present embodiment has been done following optimization on the basis of embodiment 1 or embodiment 2: the outer circumference face that described cylinder body 4 is positioned at infusion hole 7 is also radially provided with two symmetrically arranged screwed holes 3.
There is certain resistance while considering instrument precession locking nut in the present embodiment, screws for convenience, and it is to apply a downward pressure that people personnel are generally installed, people personnel consumption power after permanent installation is installed larger, both hands are very easily tired, therefore, and for reducing the working strength of installation personnel, make to install more laborsaving, can be threaded and there is the weight of constant weight at screwed hole 3, for the downward weight of reinforcement instrument, reduce the working strength of installation personnel, improved installation effectiveness and quality, practical.
Embodiment 4
The present embodiment has been done following optimization on the basis of above-mentioned arbitrary embodiment: described cylinder body 4 outer circumference surfaces are also provided with hatching knurling.
The present embodiment considers that installation personnel hand speckles with oil stain, when with hand precession nut, need to carry out precession with gloves and rag, and during precession, frictional force is less, hand easily skids, impact is installed, therefore spy is also provided with hatching knurling at cylinder body 4 outer circumference surfaces, for increasing the frictional force of hand and cylinder body 4, is convenient to install.
Embodiment 5
The present embodiment has been optimized cylinder body on the basis of above-mentioned arbitrary embodiment, is specially: described cylinder body 4 adopts chromansil steel to make.
There are wearing and tearing in long-term use of the interior hexagonal jack 5 of the cylinder body 4 in the present embodiment and outer-hexagonal joint 1, in the course of time may damage, and because instrument generally uses in factory, affected by environmently very easily be subject to corruption, therefore, the present embodiment adopts chromansil steel to make cylinder body 4, and chromansil hardness of steel is high, corrosion-resistant and wear-resistant, can meet permanent use of instrument and can not be out of shape, greatly extend service life.
Be as mentioned above embodiments of the invention.The present invention is not limited to above-mentioned embodiment, and anyone should learn the structural change of making under enlightenment of the present invention, and every have identical or close technical scheme with the present invention, within all falling into protection scope of the present invention.
