The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
Embodiment 1
As Fig. 1, valve gap bolt loading and unloading tool a kind of easy to use shown in Fig. 2, comprise and horizontally rotate plate 3, elevating lever 4 and locating support, described locating support comprises the locating ring 9 of upper end and is connected to two support bars 10 of locating ring 9 lower ends, described locating ring 9 axis places arrange stem through-hole 7, described locating ring 9 peripheries are provided with buckling groove 8, describedly horizontally rotate plate 3 lower ends, middle part and mate with locating ring 9, and horizontally rotate plate 3 and be also provided with the bail wire 6 coordinating with buckling groove 8, describedly horizontally rotate plate 3 middle parts and be provided with equally valve rod hole, described elevating lever 4 is equidistantly arranged on and horizontally rotates plate 3 two ends, on described elevating lever 4, lower two ends are connection of rotating bar 2 and hexagonal shoulder nipple 5 respectively, and described hexagonal shoulder nipple 5 is threaded with elevating lever 4.
When the present embodiment is used, support bar 10 is placed on to location, valve gap end face middle part and compresses by pressing element, valve rod is through stem through-hole 7 and valve rod hole, horizontally rotate the corresponding valve gap bolt of elevating lever 4 of plate 3 both sides, by the corresponding bolt of hexagonal shoulder nipple 5 and with hex bolts head, coordinate, assembly crewman is dwang 2 hexagonal shoulder nipples of turn simultaneously 5 at hand-held two ends again, thereby bolts at two ends is screwed.
The plate 3 that horizontally rotates in the present embodiment is connected with buckling groove 8 by bail wire 6 with locating support, and horizontally rotating plate 3 can rotate in horizontal plane, thereby when screwing the corresponding bolt of valve gap, only need rotation to horizontally rotate plate 3 and make bolt corresponding to hexagonal shoulder nipple 5, thereby screw different bolts, complete screwing of all bolts, without repeatedly fixing and unload lower support bar, reduce tool positioned and regular time and step, simplified assembly process, extremely easy to use.
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 5 corresponding bolt a of difference and bolt e, by elevating lever 4, 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 5 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.
