Description

[Detailed description of the invention] This invention relates to the improvement of the hanging fittings used for transporting and constructing the reflux pipe of the RH device, and aims to improve the safety and simplicity of the attachment and detachment operations.

Hitherto, as a hanging metal fitting of this type, Japanese Utility Model Publication No. 57-6960 is known, in which the hanging metal fitting is held between a presser metal fitting and a receiving metal fitting, and the two are tightened with bolts.

That is, a bolt with a handle on its head is passed through the presser metal object and engaged with the receiving metal object, and the bolt and/or the nut screwed onto the bolt are tightened, thereby allowing the aforementioned presser metal object and the receiver object to be connected to each other. This is a brick setting hardware that holds the bricks in place.

However, with the above hanging bracket, the circulation pipe cannot be
In the work of removing the hanging metal fittings after setting them in the predetermined position in the lower tank of the RH equipment, after the bolts are released, the holding metal fittings are placed in the narrow lower RH tank.
In addition, each receiving metal item must be collected outside the tank, and at least two or more construction workers are required.
Moreover, appropriate work must be done inside and outside the tank. Additionally, RH equipment is generally installed at high places, making work outside the tank extremely dangerous.

This idea was made in view of the problems mentioned above.
To provide a safe and simple hanging fitting that allows a recirculation pipe brick to be attached and detached from only one side, eliminates any work outside the tank by a furnace builder.

This devised hanging fixture will be described in detail below with reference to the embodiments shown in Figures 1 to 5 of the drawings. 1 is a return pipe made of bricks, 2 is an elongated rectangular upper holding plate, and long holes 4, 4 are formed on both sides of the central part. are drilled in each case, and a hanging hand 3 is provided. Note that the left and right long holes 4, 4 may be formed into a series of long holes 4 integrally connected, if there is no problem with strength or the like. Reference numerals 5 and 5 denote bolts each having an approximately semicircular lower receiving plate 6 integrally attached to the lower end thereof, which is smaller than the semicircle of the hole of the circulation pipe 1, which can be inserted into the hole of the circulation pipe 1;
The bolts 5 and 5 are inserted into the reflux tube 1 so that the lower receiving plate 6 at the lower end thereof is located slightly below the lower end surface of the reflux tube 1, and the upper part of each is inserted into the reflux tube 1. are inserted into the left and right elongated holes 4 of the upper holding plate 2 placed across the center of the upper end surface, respectively;
Nuts 7 are screwed into the upper end portions of each of them that protrude upward. Then, the left and right bolts 5, 5 are moved in the centrifugal direction (in the direction of the arrow in FIG. 2) along the left and right elongated holes 4, 4 of the upper holding plate 2, respectively, and both nuts 7, 7 are screwed, respectively. Drawings 1-3
As shown in the figure, the circulation pipe 1 can be held between the upper holding plate 2 and the left and right lower receiving plates 6, and by unscrewing both nuts 7, 7, respectively, the left and right bolts 5, 5 are moved in the opposite centripetal direction (in the opposite direction). The left and right bolts 5 and the upper retaining plate 2 can be removed from the circulation pipe 1 by moving them in the directions shown in FIG. This is what happens. The upper holding plate 2 may be, for example, a doll with three projecting plates protruding radially from the center as shown in FIG. It is also possible to use a structure in which three or four bolts 7 are used, such as a cross-shaped structure in which long holes 4 are bored in each of the four projecting plates.

As mentioned above, the suspension fitting of this invention moves centrifugally along the elongated hole of each bolt, clamps the circulation pipe between the upper holding plate and the lower receiving plate by screwing the nut, and returns the reflux pipe by screwing the nut back down. Since it is possible to release the clamp and remove it upward by moving in the centripetal direction, the reflux tube can be removed easily.
The work of setting the RH equipment at the specified position in the lower tank and removing and recovering the hanging fittings after setting can be done extremely easily, conveniently, quickly and in a short time without requiring the troublesome time and labor required in the past. It has an outstanding effect. Furthermore, in terms of safety, the hanging metal fitting of this invention eliminates the need for collection work outside the tank at a high place, which eliminates danger and has the excellent effect of allowing work to be performed with a high degree of safety.
