DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dedicated tool for attaching and detaching a spray tip for spraying cooling water in a continuous casting facility.

[0002]

2. Description of the Related Art In continuous casting equipment, slabs are cooled by injecting cooling water from gaps between rolls. Generally, industrial water is used as cooling water. Due to this, the spray tip is easily clogged.
If the spray tip is clogged, insufficient cooling or uneven cooling occurs, which has a serious adverse effect on the casting operation and the quality of the slab. Therefore, the inspection, cleaning, and reassembling must be performed periodically.

[0003]

However, the interval between the rolls in the continuous casting equipment is extremely small, and the mounting position of the spray tip is located deep in the roll surface. It was difficult and sometimes had an inconvenient work posture. In addition, the spray tip is made of stainless steel for the purpose of rust prevention, and the suction means using magnetic force has no effect. Improvement was desired.

The present invention addresses such disadvantages of the prior art,
That is, it was devised to improve the point of low workability of spray tip attachment / detachment, and the main purpose is to improve the spray tip attachment / detachment tool which can improve work efficiency and work stability. Is to provide.

[0005]

SUMMARY OF THE INVENTION According to the present invention, there is provided a spray tip attaching / detaching tool, which is fixed to a nipple attached to a pipe with a cap nut, by using a socket for engaging the cap nut. wrench and an outer cylinder member formed on one end, and the inner cylinder member fitted freely relative rotation respect to the outer cylinder member, socket wrench end of the inner cylindrical member

The end on the trench side is elastically urged in the expanding direction, and
The direction in which the gap between the opposing surfaces increases as the distance from the fulcrum increases
Multiple slopes are provided at the end on the side opposite the socket wrench.
And chuck members, retractably in the axial direction by the rotation
Threaded to the inner cylinder member and formed at the tip of the
The slope of the chuck member with the tapered end
The socket wrench side end of the chuck member is closed
And a rod member for possess, Fukurona socket wrench
Sput that engages with the socket and protrudes from the end face of the cap nut.
While holding the tip of the laser chip with the chuck member,
Giving relative rotation between nut and spray tip
Is achieved by making it possible.

[0006]

According to the above construction, by screwing the rod member having the tapered end, the chuck member grasps the tip of the spray tip, and in this state, the socket wrench of the outer cylinder member is engaged with the cap nut. By rotating the spray tip, the spray tip can be detached together with the cap nut.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The construction of the present invention will be described below in detail with reference to specific embodiments shown in the accompanying drawings.

FIG. 1 shows an example of a spray tip attaching / detaching tool 1 constructed according to the present invention. The attachment / detachment tool 1 is composed of an inner cylinder member 2 and an outer cylinder member 3 which are double-fitted inside and outside, and a chuck member 4 composed of two small pieces provided at one end of the inner cylinder member 2.

A socket wrench 5 is formed at one end of the outer cylinder member 3. The inner cylinder member 2 is fitted in the outer cylinder member 3 so as not to move relatively in the axial direction and to be relatively rotatable. A handle 6 for rotating the socket wrench 5 is fixed to the other end of the outer cylinder member 3, and a handle 7 for rotating the inner cylinder member 2 is provided at the other end of the inner cylinder member 2. It is fixed.

The chuck member 4 can be tilted in a seesaw manner with a pin 4a inserted in the middle of the chuck member 4. The outer periphery of the chuck member 4 is controlled by a coil spring 8 contracted inside its outer end. Is always biased to open.

An inclined surface 4b is formed on the inner surface of the chuck member 4 on the inner end side so that the interval between the end portions is more widened. One end is engaged. And this rod member 9
The inner cylinder 2 has a screw portion 9b formed on the other end side.
Screw connection.

Next, the procedure for handling the tool will be described.

[0013] The nozzle tip C which can be detached with this tool is:
As shown in FIGS. 2 and 3, a nipple N screwed to the socket S of the pipe is fixed via a cap nut A.
Therefore, first, the tip of the tool 1 is inserted through the gap G between the rolls R, and the socket wrench 5 is engaged with the cap nut A. At the same time, the inner cylinder member 2 is rotated so that the nozzle tip C
The chuck member 4 is engaged with the tip of the
By twisting a knob 9c fixed to the other end, a tapered end 9a is formed between the inclined surfaces 4b on the inner end side of the chuck member 4.
Into the nozzle tip C between the outer ends of the chuck member 4.
Firmly sandwich the tip of Then, the chuck member 4 tightens the nozzle tip C.
This can be confirmed by the fact that the handle 7 provided on the other end side does not rattle.

In this state, if the cap nut A is loosened and removed, the nozzle tip C is removed together with the cap nut A.

When mounting, the procedure may be reversed.

[0016]

As described above, according to the present invention, the tip of the nozzle tip can be easily grasped and rotated by inserting it into the narrow gap between the rolls. Therefore, since the nozzle tip can be attached and detached without being forced to perform an unstable work posture and without being accidentally dropped, a great effect can be obtained in improving work efficiency.
