Description

The jig apparatus for the gear-box separation

The present invention relates to a jig device capable of stably separating a gearbox from a valve body to prevent safety accidents as well as prevent stress on the gearbox occurring during the separation process.

In general, a valve refers to a device that controls the flow rate, flow velocity, pressure, etc. of a fluid flowing through a pipe, and a ball valve, a type of valve, is a 90 degree rotation valve, has very good airtightness, and the seat surrounding the ball to ensure airtightness and also has a relatively low operating torque.

In addition, the flow resistance of the ball is very low, so the applicability of the ball valve is very diverse.

The body type of these ball valves is determined by how many pieces the body is composed of. Almost all ball valves are 2-piece or 3-piece because of the ease of design, manufacturing, and maintenance. It is divided into a floating type and a trunnion type, and there are a top entry type and a side entry type according to the ball insertion method.

In particular, a gearbox is applied to a ball valve installed as a side entry type. In order to maintain such a gearbox, when the gearbox, which is fitted and fixed on the stem of the ball valve body, is to be separated from the ball valve, the external force of a special vehicle such as a crane is towed to the upper part of the gearbox through a wire (lifting) to be withdrawn.

That is, a wire such as a chain (chain) is wound around the gearbox to be separated and the gearbox is separated from the ball valve through the lifting force of the specially equipped vehicle.

However, when the wire is wound on the outer surface of the gearbox that is strongly coupled to the ball valve (for example, due to foreign matter from long-time use or foreign matter contained in the flowing fluid), the center of gravity is unbalanced. Equipment damage such as deformation (stress) or breakage of the equipment due to the sudden separation of the gearbox from the shaft causes safety accidents such as equipment damage or operator injury.

Hereinafter, a jig device for separating a gearbox according to the present invention (hereinafter, simply referred to as a 'jig device') according to the present invention will be described in detail with reference to the accompanying drawings.

First, as shown in FIGS. 1 and 2, the jig device 1 according to the present invention largely includes a jig body 110 and an extension flange 200, and through this configuration, fastening means such as bolts (P) ) is disposed between the valve body (B-B) coupled to each other and the gearbox (G-B), which is a heavy object, and the corresponding gearbox (G-B) can be easily separated through the external force of the separating means 300 It is realized.

In more detail, the jig body 110 is a pair of bodies 110 made of two powders symmetrically to each other as shown in FIG. It is a configuration for separating the gearbox (G-B) from the valve body (B-B) by the external force of the separating means (300) by combining in the form of a ring (RING) having a hollow part.

For example, each body 110 is formed of a metal material or the like, and is formed in an arc shape as a whole, and is provided on both sides to connect with one side of the extension flange 200 .

An insertion groove 111 is formed in the longitudinal direction on the upper surface of the body 110 that faces the lower surface of the gearbox (G-B), and the insertion groove 111 is formed with a protrusion 121 protruding downward from the lower surface of the buffer member 120 and By fitting and detachably fitting the shape, the gearbox (G-B) and the upper surface of the body 110 are not only prevented from being damaged by the elastic force of the buffer member 120 when the upper surface is in contact with each other, but also separated from the valve body (B-B) By absorbing vibrations that may occur during operation, it is possible to reduce the stress on the gearbox (G-B).

To this end, the buffer member 120 is molded of a material capable of elastically restoring elasticity, such as rubber or urethane.

And, the extension flange 200 is a pair of body 110 is coupled in the shape of a ring by the fastening means (P) to support the lower gear box (G-B), and at the same time, the separation means (300) It is a configuration for providing a force that can be separated by receiving the traction force of the gear box (G-B) through the body (110).

For example, the extension flange 200 has a shape in which one side is connected to both sides of each body 110 and protrudes outward to have the shape of a bar, and at least one fastening hole 210 is perforated in the longitudinal direction. When the pair of the bodies 110 are coupled to each other, the fastening means P is inserted through the fastening holes 210 opposite to each other so that the ring-shaped jig member 100 shape can be completed. .

On the other hand, with further reference to FIG. 3 , the extension flange 200 in the present invention has a through hole 220 through which the traction wire W is inserted in addition to the fastening hole 210 according to the type of the separation means 300 . A gearbox whose lower surface is supported by the jig body 110 by exercising an external force to lift the traction wire (W) inserted through the through hole 220 by a specially equipped vehicle such as a crane (G-B) can be separated from the valve body (B-B).

As an example, the separation means 300 that provides an external force for lifting the gearbox G-B raises the load by pumping when replacing the tire of the vehicle, and raises the vehicle supported by the rod to a certain height. In the case of a normal jack (10: Jack) for lifting with a furnace, the jig member 100 coupled in a ring shape by the fastening means (P) between the gear box (G-B) and the valve body (B-B) is installed so that it can be disposed. do.

Here, the jack 10 is arranged in a plurality of configurations to be located under the extension flanges 200 formed on both sides of the body 110 as shown in FIG. 4 and supported by the jig body 110 Gearbox (G-B) It is preferable not to disturb the balance in either direction when separating from the valve body (B-B).

After that, the operator pumps the lifting bar 13 several times in a state where each jack 10 is supported on the ground (floor surface) so that the rod 11 rises from the inside of the corresponding jack 10 to the upper direction. However, in this process, the upper surface of the rod 11 rising in the process is made to be in contact with the lower surface of the extension flange 200 so that the gearbox (G-B) supported on the jig member 100 through the rise is the valve body (B-B) will receive a force that can be separated from

At this time, the jig member 100 used to separate the gearbox G-B is moved and stored integrally with the corresponding gearbox G-B so as not to be removed, and the gearbox G-B is re-coupled to the valve body B-B. When the lower surface of the extension flange 200 is seated on the upper surface of the rod 11 maintained in an elevated state at the time, the pressure applied to the jack 10 is relieved, so that the gearbox (G-B) and the valve body (B-B) are quickly reunited with each other. It is desirable to allow

Of course, the separation and coupling of the gearbox (G-B) using the jack (10) may be performed together with the help of a specially equipped vehicle using the traction wire (W) according to the weight of the corresponding gearbox (G-B).

On the other hand, as shown in Figure 5, when the separation means 300 for providing an external force for lifting the gearbox (G-B) is a specially equipped vehicle (not shown), a through hole formed in each extension flange 200 ( After fastening the traction wire (W) to 220), the external force to be lifted by connecting the central part of the traction wire (W) to the special vehicle is applied to the jig member 100 so that the balance of the gearbox (G-B) to be separated is maintained. It is transmitted so that the corresponding gearbox (G-B) can be easily and quickly separated from the valve body (B-B). This results in a reunion.
