本考案は、ランスパイプなどの、耐火筒外周面
を補修するパツチング補修装置に関するものであ
る。[Detailed Description of the Invention] The present invention relates to a patching repair device for repairing the outer peripheral surface of a refractory cylinder such as a lance pipe.
従来、溶融金属に、浸漬するランスパイプの浸
漬部の損傷の補修は、吹付け補修、パツチング補
修が行なわれているが、これらの補修手段には、
次のような問題点がある。 Conventionally, damage to the immersed part of a lance pipe that is immersed in molten metal has been repaired by spraying or patching.
There are the following problems.
吹付け補修は、耐火性骨材と、バインダーおよ
び水をあらかじめ混合し、スラリー状にしたもの
を吹付け機を用いて、吹付ける湿式吹付け法が採
用されているが、耐火材料のリバウンドロスが多
いことから、粉塵発生があつて、作業環境を悪化
したり、また補修面と耐火材料との接着度が弱
く、強固な再被覆層を確保することができない。 For spraying repair, a wet spraying method is used in which fire-resistant aggregate, binder and water are mixed in advance and made into a slurry using a spraying machine, but the rebound loss of the fire-resistant material is As a result, dust is generated, which worsens the working environment, and the degree of adhesion between the repaired surface and the fireproof material is weak, making it impossible to secure a strong recoating layer.
また、パツチング補修は、プラスチツク耐火物
を損傷部に、手で押し付けて補修する手段では、
リバウンドロス、および粉塵発生の必配はない
が、作業者による手作業が主であるため、亀裂部

た熱間（被補修面温度500〜700℃程度）での高温
作業となり作業環境面でも問題がある。したがつ
て粉塵発生の心配がないパツチング補修の手作業
にかわる自動化が強く望まれている。 In addition, patching repair is a method of repairing by manually pressing plastic refractories onto the damaged area.
Although rebound loss and dust generation are not inevitable, since it is mainly done manually by workers, it is not possible to fill cracks etc. sufficiently and the effect is small. In addition, there are problems in terms of the working environment as the work is carried out at high temperatures (temperature of the surface to be repaired is approximately 500 to 700°C). Therefore, there is a strong desire for automation that can replace manual patching repairs without the risk of dust generation.

ことができる。 The lance pipe patching repair device of the present invention having the above structure includes a cylindrical thin plate spring 1 lined with a plastic repair material 14 in advance.
The hooking hole (elongated hole) 12 of 1 is connected to the support hand 2,
When the cylindrical thin plate spring 11 is applied to the hooking claws 3, 3' (detailed in FIG. 2) of the arms 1, 2' and the output shaft 7 of the arm opening/closing cylinder 6 is moved backward (downward in the drawing) 1' and cylindrical thin leaf spring 1
1 is opened as shown in FIGS. 1, 3, and 4.
In this state, in the damaged part of the lance pipe 13 that requires repair,
An external force that presses and opens the cylindrical thin plate spring 11,
That is, by moving the output shaft 7 of the opening/closing cylinder 6 forward (upward in the drawing), the cylindrical thin plate spring 11 moves the lance pipe with the restoring force of the cylindrical thin plate spring 11, as shown in FIGS. The repair material 14 can be pressure-bonded to the damaged part and repaired by patching.

チング補修作業を終る。 The repair material 4 is completely attached to the lance pipe 13,
When the coating and patching repairs are completed, the output shaft 7 of the arm opening/closing cylinder 6 is further advanced (upwards in the drawing), the arms 1 and 1' are closed, and the hook 3' and the cylinder are closed as shown in Fig. 7b. The upper part of the thin plate spring 11 is released, the support stage (not shown) of the lance pipe 13 is raised, and the hooking hole 12 (elongated hole) is inserted into the seventh hole.
The arms 1 and 1' are separated as shown in Fig. c, the output shaft 7 of the arm opening/closing cylinder 6 is moved backward, the arms 1 and 1' are opened, and the support hands 2 and 2' are separated from the lance pipe 13 to complete the patching repair work.

きる。 By making the diameter of the cylindrical thin plate spring almost the same as the diameter of the lance pipe, the cylindrical thin plate spring will retain the repair material in its natural state (without applying any external force) when the repair material is crimped. The restoring force remains in the cylindrical thin plate spring by the thickness of . In other words, the repair material is pressurized evenly from the outer periphery of the cylindrical thin plate spring, penetrates into the damaged part of the surface to be repaired, and can be repaired by patching.
また円筒形状薄板ばねの厚みは約0.1〜10ｍ／
ｍあれば復元力は充分であり、補修材料を圧着す
ることができる。 In addition, the thickness of the cylindrical thin leaf spring is approximately 0.1 to 10 m/
m, the restoring force is sufficient and the repair material can be crimped.
円筒形状薄板ばねの長さは約50〜2500ｍ／ｍ程

周補修にも適用できるものである。 The cylinder of the opening/closing mechanism of the present invention may be driven by either hydraulic pressure or pneumatic pressure, but it is preferable to use a hydraulic cylinder since it generates a large force. Also,
Although the lance pipe patching repair device of the present invention has been described as being applied to lance pipes, it is not limited thereto, and can also be applied to repairing the outer periphery of similar cylindrical refractories.
以上、説明したように、本考案のランスパイプ
のパツチング補修装置は、下記の効果がある。 As described above, the lance pipe patching repair device of the present invention has the following effects.
従来の補修ではパツチング補修材料を損傷部に
圧着させる時間が短いので充分な接着力が得られ
なかつたが、円筒形状薄板ばねの復元力により長
時間圧着することができる。 In conventional repairs, the time required to press the patching repair material onto the damaged area is short, so sufficient adhesion force cannot be obtained, but the restoring force of the cylindrical thin plate spring allows for long-term pressure bonding.

したままで使い捨て使用することもできる。 Various shapes and dimensions are available depending on the size of the repaired area. Further, the cylindrical thin plate spring can be removed and reused after the patching repair is completed and the repair material is sufficiently crimped onto the damaged area. Alternatively, the cylindrical thin plate spring can be used disposable while attached to the lance pipe.
