Abstract
The utility model discloses an auxiliary installation tool of a hydraulic cylinder sealing element, which is integrally a component in a taper sleeve shape, wherein the length of the taper sleeve is equal to or larger than the length of a small diameter section of the external thread at the outer end of a piston rod of a hydraulic cylinder, the outer diameter of the large-diameter end of the taper sleeve is consistent to the diameter of the piston rod, the inner diameter of the large-diameter end of the taper sleeve is larger than the inner diameter of the small-diameter end, and an internal thread matched with the external thread at the outer end of the piston rod is arranged in the small-diameter end. The utility model used for assembly can greatly improve the installation quality and efficiency of the sealing element, and has the advantages of convenient installation and no damage on a sealing ring.
Description
Technical field
The utility model relates to the seal auxiliary mounting tool of hydraulic cylinder when assembling that adopts in a kind of iron-smelter blast-furnace equipment.
Background technology
Existing a kind of iron-smelter State of Blast Furnace open front machine rotating hydraulic cylinder, this hydraulic cylinder generally is formed by connecting by front cylinder base, cylinder body, back cylinder seat, when mounted, again front cylinder base, cylinder body and back cylinder seat are connected as a single entity after earlier piston rod being packed into front cylinder base, adopt the sealing of " V " type to form slipper seal between piston rod and the front cylinder base and is connected, this " V " type hermetically-sealed construction generally is made up of support ring, sealing ring, pressure ring three parts.When " V " type of installation hermetically-sealed construction, following two kinds of mounting means are arranged generally: a kind of is after being installed in support ring, sealing ring, pressure ring on the front cylinder base earlier, piston rod to be assembled on the front cylinder base again; Another kind is after earlier piston rod and front cylinder base being assembled, support ring, sealing ring, pressure ring to be moved on the front cylinder base installation site by piston rod successively install again.First kind of mode wherein, because the piston rod outer end has the external thread section of a minor diameter, this minor diameter thread segment is used for being connected with the hydraulic cylinder cylinder head, and described outer end to piston rod is positioned at an end of hydraulic cylinder outside, so this thread segment and step place damage the sealing ring epipharynx easily; And the second way because sealing ring must be enclosed within and move on the piston rod, is difficult to the balance application of force, also causes the sealing ring inner lip to damage easily, and also possesses long defective of set-up time simultaneously.
So existing two kinds of mounting means all possess defectives such as the sealing ring epipharynx is destroyed easily, set-up time length, installation quality difference.
The utility model content
Technical problem to be solved in the utility model is, overcomes above-mentioned the deficiencies in the prior art and provides a kind of easy for installation and can not damage the hydraulic cylinder sealing element auxiliary mounting tool of sealing ring epipharynx.
In order to solve the problems of the technologies described above, adopted following technical scheme in the utility model:
A kind of hydraulic cylinder sealing element auxiliary mounting tool, its integral body is a tapered sleeve shape member, described tapered sleeve length is equal to or greater than the external screw thread reduced diameter section length of hydraulic cylinder piston rod outer end, tapered sleeve larger diameter end external diameter is consistent with diameter of piston rod, described tapered sleeve larger diameter end internal diameter is greater than the smaller diameter end internal diameter, and is provided with the internal thread with piston rod outer end external screw thread coupling in smaller diameter end.
When using this auxiliary mounting tool fitting tight part, earlier be installed in support ring, sealing ring, pressure ring three seals on the front cylinder base successively, again the utility model is socketed in the piston rod outer end, the external screw thread reduced diameter section of piston rod outer end is screwed on the tapered sleeve smaller diameter end internal thread, and make tapered sleeve larger diameter end step place direct and the piston rod outer end offset, because tapered sleeve larger diameter end external diameter is consistent with diameter of piston rod,, step place, piston rod outer end seamlessly transits so forming.At this moment, can pass through seal by shilling tapered sleeve shape member that the piston rod outer end fixes, thereby avoid the seal epipharynx directly to contact with step, make it avoid being scratched damage by piston rod outer end screw thread or step with piston rod outer end screw thread.During concrete enforcement, can also be coated with lubricating grease in the tapered sleeve appearance and reduce friction, further improve assembling speed and safety guarantee.
In sum, adopt the utility model to assemble, can improve seal installation quality and installation effectiveness greatly, possess easy for installation and can not damage the advantage of sealing ring.
Description of drawings
Fig. 1 is a cross-sectional view of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
During concrete enforcement, as shown in Figure 1, a kind of hydraulic cylinder sealing element auxiliary mounting tool, its integral body is a tapered sleeve shape member 3, its tapered sleeve length is equal to or greater than the external screw thread reduced diameter section length of hydraulic cylinder piston rod outer end, tapered sleeve larger diameter end 1 external diameter is consistent with diameter of piston rod, and described tapered sleeve larger diameter end 1 internal diameter is greater than the smaller diameter end internal diameter, and is provided with the internal thread 2 with piston rod outer end external screw thread coupling in smaller diameter end.
