Abstract
The utility model relates to a descaling injection valve bushing detaching tool. The tool comprises lifting nuts, a transverse bar, a lifting screw rod, a drag hook base, an opening adjuster and drag hooks, wherein a rod hole for mounting the lifting screw rod is formed in the center of the transverse bar, the lifting nuts installed in a concave face of the transverse bar are fixed to the two ends of the lifting screw rod, the drag hook base is connected to the tail end of the lifting screw rod through threads, the drag hook base is subjected to spot welding after being installed in place, the drag hook base is connected with the two symmetrical drag hooks through cylindrical pins, and the size of the opening between the two drag hooks is adjusted through the opening adjuster. The detaching speed is high and detaching is safe; the detaching work can be completed by just one person, the working efficiency is greatly improved, and the labor intensity is reduced.
Description
Technical field
The utility model belongs to metallurgy industry Pressure Water Scale Removing technical field, relates to a kind of descaling injection valve bushing dismounting instrument.
Background technology
Descaling injection valve is mainly made up of cylinder or hydraulic cylinder, spool, lining, control valve and seal etc., and descaling injection valve is easily damaged at wash away bottom spool, lining and the seal of water under high pressure, and often, lining dismounting frequency is high in the maintenance of descaling injection valve.In the process of maintenance, general use driving firmly up draws to take out lining, at space for maintenance narrow and small or without driving place just pull out lining by guide chain, these two kinds methods of removing lining all cannot be fixed guide chain or steel wire rope, cause taking out fast lining, even owing in the situation such as excessive that skews in demolishing process, exerts oneself, lining and injection valve valve body mating surface being damaged.So just increase labour intensity and repair time, also strengthened the probability that damages lining simultaneously, if affected greatly especially normal production in the time of repairing.
Utility model content
In order to overcome the above-mentioned shortcoming of prior art
,the utility model provides a kind of simple in structure, dismounting quick and safe, dismounting time only to need a people just can complete the descaling injection valve bushing dismounting instrument of dismantlement work feature
.
The utility model solves the technical scheme that its technical problem adopts: a kind of descaling injection valve bushing dismounting instrument, comprise lifting nut, whippletree, lifting screw, drag hook seat, opening adjuster and drag hook, be provided with the bar hole that lifting screw is installed in the center of whippletree, be fixed with at lifting screw two ends the lifting nut being arranged in whippletree concave surface, end at described lifting screw adopts the drag hook seat that has been threaded, after being in place, drag hook seat is carried out to spot welding, on drag hook seat and between two drag hooks of symmetry, be connected by straight pin, drag hook regulates the openings of sizes between two drag hooks by opening adjuster.
Installed thrust bearing between described lifting nut and whippletree.
Be processed with the installing hole that adjusting screw(rod) is installed at described lifting screw center.
On described drag hook seat with groove and the pin hole of drag hook is installed.
Described drag hook is crank arm type.
Described opening adjuster is made up of adjusting screw(rod) and lifter plate.
The beneficial effects of the utility model are: in use can be because of in the situation such as excessive that skews in demolishing process, exerts oneself, lining and injection valve valve body mating surface being damaged; Fast and the safety of dismounting speed; When dismounting, only need a people just can complete dismantlement work, greatly improved operating efficiency, reduced labour intensity.
Brief description of the drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model embodiment 1 structural representation.
In figure: 1-lifting nut, 2-whippletree, 3-lifting screw, 4-drag hook seat, 5-opening adjuster, 6-drag hook, 7-valve body, 8-lining.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Referring to Fig. 1, a kind of descaling injection valve bushing dismounting instrument, comprise lifting nut 1, whippletree 2, lifting screw 3, drag hook seat 4, opening adjuster 5 and drag hook, be provided with the bar hole that lifting screw 3 is installed in the center of whippletree 2, be fixed with at lifting screw 3 two ends the lifting nut 1 being arranged in whippletree 2 concave surfaces, installed thrust bearing between lifting nut 1 and whippletree 2, be processed with the installing hole that adjusting screw(rod) is installed at lifting screw 3 centers, end at lifting screw 3 adopts the drag hook seat 4 that has been threaded, after being in place, drag hook seat 4 is carried out to spot welding, on drag hook seat 4 with groove and the pin hole of drag hook 6 is installed, on drag hook seat 4 and between two crank arm type drag hooks 6 of symmetry, be connected by straight pin, drag hook 6 regulates two openings of sizes between drag hook 6 by opening adjuster 5, opening adjuster 5 is made up of adjusting screw(rod) and lifter plate.
Embodiment 1: referring to Fig. 2, drag hook 6 is slowly put into lining 8, whippletree 2 is seated on injection valve valve body 7, adjusting opening adjuster 5 increases the opening of its drag hook 6, in the gib head of drag hook 6 enters lining 8 windows completely time, do not adjusting, rotation and lifting nut 1 up moves lifting screw 3, and under the effect of drag hook 6 and opening adjuster 5, lining 8 up moves, until until seal separate with sealing surface.
In use can be because of in the situation such as excessive that skews in demolishing process, exerts oneself, lining 8 and injection valve valve body mating surface being damaged; Fast and the safety of dismounting speed; When dismounting, only need a people just can complete dismantlement work, greatly improved operating efficiency, reduced labour intensity.
