Summary of the invention
The invention provides a kind of bolt loading and unloading servicing unit, while having solved valve gap assembling in the past, assemble weak effect, and the problem that can not assemble for the valve gap of different-diameter.
For solving above-mentioned technical problem, the present invention is by the following technical solutions: a kind of bolt loading and unloading aid, the support bar that comprises elevating lever, level board, locking nut and threaded joint, described level board middle part is provided with stem through-hole, described level board is positioned at stem through-hole both sides a plurality of installing holes that have been arranged in a linear, described support bar be take the vertical axis of stem through-hole and is equidistantly arranged two as center line, and the nipple of described support bar is locked by described locking nut through after installing hole; Described elevating lever penetrating mounting holes and the vertical axis of the stem through-hole of take are equidistantly provided with two as center line, described elevating lever is positioned at support bar outside, described elevating lever upper/lower terminal is connection of rotating bar and hexagonal shoulder nipple respectively, and described hexagonal shoulder nipple is threaded with elevating lever.
Described support bar lower end is provided with locating piece.
Any one end of described dwang is provided with interior spliced eye.
The circumferential surface at described dwang two ends is provided with hatching knurling.
Compared with prior art, the invention has the beneficial effects as follows: this bolt loading and unloading aid of the present invention's design, easy to use, not only can well assist assembling valve gap, improve assembly precision and quality, guarantee that valve gap compresses evenly, guarantees valve bonnet seal simultaneously, and can be used for the valve gap assembling of multiple diameter, practical.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
Fig. 1 is structural representation of the present invention.
Fig. 2 is that valve gap bolt of the present invention screws schematic diagram.
Label in figure is expressed as: 1, interior spliced eye; 2, dwang; 3, elevating lever; 4, level board; 5, installing hole; 6, hexagonal shoulder nipple; 7, locking nut; 8, stem through-hole; 9, support bar; 10, locating piece.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is further illustrated.
Embodiment 1
A kind of bolt loading and unloading aid as shown in Figure 1 and Figure 2, the support bar 9 that comprises elevating lever 3, level board 4, locking nut 7 and threaded joint, described level board 4 middle parts are provided with stem through-hole 8, described level board 4 is positioned at stem through-hole 8 both sides a plurality of installing holes 5 that have been arranged in a linear, described support bar 9 be take the vertical axis of stem through-hole 8 and is equidistantly arranged two as center line, and the nipple of described support bar 9 through installing hole 5 after by described locking nut 7 lockings; Described elevating lever 3 penetrating mounting holes 5 and take the vertical axis of stem through-hole 8 and be equidistantly provided with two as center line, described elevating lever 3 is positioned at support bar 9 outsides, described elevating lever 3 upper/lower terminals are connection of rotating bar 2 and hexagonal shoulder nipple 6 respectively, and described hexagonal shoulder nipple 6 is threaded with elevating lever 3.
When the present embodiment is used, support bar 9 is placed on to valve gap end face middle part, valve rod is through stem through-hole 8, the corresponding valve gap bolt of elevating lever 3 of level board 4 both sides, by the corresponding bolt of hexagonal shoulder nipple 6 and with hex bolts head, coordinate, assembly crewman is dwang 2 hexagonal shoulder nipples of turn simultaneously 6 at hand-held two ends again, thereby bolts at two ends is screwed.When the valve gap assembling for different-diameter, can be according to the spacing of two support bars 9 of diameter adjustment, so that support bar 9 can keep balance when instrument uses, be convenient to assembling, simultaneously also can be according to valve gap diameter adjustment elevating lever 3 spacing, so that hexagonal shoulder nipple 6 can corresponding corresponding bolt, thereby meet the assembling demand of multiple diameter valve gap, make instrument more practical.
When bolt screws, described in the present embodiment, servicing unit compresses valve gap in conjunction with symmetry assembling mode, as shown in Figure 2, in advance by bolt a-bolt h pretension, again this device is lain in to valve gap upper end, by two hexagonal shoulder nipples, the 6 corresponding bolt a of difference and bolt e, by dwang 2, bolt a and bolt e are screwed, while screwing, feel and can stop screwing while having certain resistance, not exclusively screw, re-using the corresponding bolt c-bolt of hexagonal shoulder nipple 4 g not exclusively screws the two, then successively by bolt b and bolt f, bolt d and bolt h not exclusively screw, finally repeating above-mentioned steps screws bolt a-bolt h successively completely again.
The servicing unit of the present embodiment can be assisted assembling bolt, and the distance of elevating lever 3 lifting under the support of support bar 9 at two ends is identical when screwing, it is identical that the bolt that can guarantee two ends screws degree, thereby bolt is evenly compressed, can prevent that valve gap from screwing inequality and causing valve gap distortion, fracture or sealing leak, increase assembly precision, guaranteed the normal lifting of valve rod and the sealing of valve gap and valve seat junction.
The hexagonal shoulder nipple 6 of the present embodiment can be changed according to bolt head size, to be applicable to the use of multiple large stove bolt.
