Abstract

The utility model discloses a flange opener which is safe, reliable and relatively high in efficiency during flange dismounting. The flange opener comprises a base station, an ejector rod, an ejector tip and brackets, wherein the ejector rod and the base station are connected through screw threads; the bottom of the ejector rod and the ejector tip are in universal ball connection; two ends of the base station are respectively hinged to one bracket; pin rolls at the upper surface of the brackets are hinged to the base station; the base station is positioned between each pair of connection boards; check rings penetrate through the pin rolls at the outer sides of the connection boards; cotters are inserted in the pin rolls at the outer sides of the check rings. When flanges are dismounted, the pointed part of the ejector tip is inserted into a gap between the two flanges, the pin rolls at the lower part of the brackets are fixed in screw holes of the flanges, the ejector rod is moved downwards by rotating the upper end of the ejector rod, the ejector tip is forced to be inserted between the two flanges to separate the flanges, and thus the exchange of a seal ring is facilitated. As the brackets and the flanges are fixed into a whole, only the ejector rod is operated to dismount the flanges, the operation efficiency is high, safety and convenience are realized, and the requirement on operation technologies of workers is not high.

Description

Flange opener

Technical field

The utility model relates to a kind of instrument, particularly dismantles the shedding motion of flange.

Background technology

Connection between pipeline is to be all spirally connected and to be fixed as one by the flange of two pipe ends conventionally.In the time carrying the easy leak materials such as gas, liquid, toward contact, sealing ring need be installed between two flanges, after service time is long, often sealing ring is aging, make to occur leakage or gas leak phenomenon between flange, now just must change sealing ring, otherwise easily cause large-area accident to occur.Traditional substitute mode mostly adopts the instruments such as crowbar, cucurbit, jack, wedge piece, pipeline flange is pried open, then changed sealing ring.When operation, be completely accustomed to arbitrarily carrying out according to workman, veteran worker and new worker's operant level differs larger, and the time used also differs widely, and fragile flange not only when new worker operates, also easily cause limb injury, and construction quality is difficult to be guaranteed.

Summary of the invention

The purpose of this utility model is to provide a kind of safe and reliable and flange opener that efficiency is higher while dismantling flange.

The technical solution of the utility model is: comprise base station, push rod, top and support, push rod and base station are spirally connected, and top is tri-prismoid, and push rod bottom is with top for multi-directional ball is connected, and base station two ends are hinged with respectively support; Described support is made up of a pair of bearing pin, a pair of connecting plate and a pair of back-up ring, and a bearing pin penetrates in the axis hole of a pair of connecting plate upper end simultaneously, and another root bearing pin penetrates this in the axis hole of connecting plate lower end simultaneously, bearing pin and connecting plate interference fit; In support, be positioned at bearing pin and base station above hinged, base station is between every pair of connecting plate, and back-up ring is through on the bearing pin in connecting plate outside, and split pin is inserted on the bearing pin that is positioned at back-up ring outside.

Owing to adopting the structure of base station, push rod, top and support in the utility model, when dismounting flange, top tip is inserted in the gap place between two flanges, the bearing pin of support bottom is fixed in the screw of flange, by turn push rod upper end, push rod is moved down, force between top insertion two flanges, flange is separated, to carry out the replacing of sealing ring.Because support and flange are fixed as one, only need operation push rod with regard to dismountable flange, not only operating efficiency is high, and safe ready, less demanding to workman's operating technology.

Detailed description of the invention

Below in conjunction with drawings and Examples, the utility model is described in further detail, but does not form any restriction of the present utility model.Shown in Fig. 1 and Fig. 2, the utility model comprises base station 2, push rod 1, top 6 and support.Push rod 1 is spirally connected with base station 2, and top 6 is tri-prismoid, and push rod 1 bottom is with top 6 for multi-directional ball is connected, and multi-directional ball is prior art, does not repeat them here.Base station 2 two ends are hinged with respectively support.Described support is made up of a pair of bearing pin 4, a pair of connecting plate 3 and a pair of back-up ring 5, and a bearing pin 4 penetrates in the axis hole of a pair of connecting plate 3 upper ends simultaneously, and another root bearing pin 4 penetrates this in the axis hole of connecting plate 3 lower ends simultaneously, bearing pin 4 and connecting plate 3 interference fit.In support, be positioned at bearing pin above 4 hinged with base station 2, base station 2 is between every pair of connecting plate 3, and back-up ring 5 is through on the bearing pin 4 in connecting plate 3 outsides, and split pin is inserted on the bearing pin 4 that is positioned at back-up ring 5 outsides.

When use, the affixed bolt of first dismantling on flange, the bearing pin of two stands bottom 4 is penetrated respectively in the corresponding screw on two flanges, make two flanges between two connecting plates 3, on the bearing pin 4 that passes flange, put back-up ring 5, on the bearing pin 4 in back-up ring 5 outsides, insert split pin, so far, support is fixing complete.Then, rotation push rod 1, makes push rod 1 move down with top 6, by top 6 junctions of aiming between two flanges, continues rotation push rod 1, makes top 6 to insert between two flanges, and two flanges are separated, and finally changes the operation of sealing ring.Because bearing pin in the utility model 4 all adopts articulated manner to be connected with connecting plate 3 and bearing pin 4 with flange with base station 2, bearing pin 4, can conveniently adjust top 6 position, the junction of rapid alignment two flanges.
