本発明は、ボイラ炉内に設置される足場用梁挿入装置及び足場用梁挿入方法に関する。   The present invention relates to a scaffold beam insertion device and a scaffold beam insertion method installed in a boiler furnace.

ボイラ炉内点検用足場を組立てる際、ボイラの操業を停止し、ボイラ炉内で作業を行うことができる温度にボイラ炉内の温度が下がってから作業員がボイラ炉内に入って作業していたため、莫大なボイラ操業停止時間を要していた。そこで、ボイラ操業停止時間を短縮するための装置として、作業員が炉内に入れない程の高温であっても温度低下を待たずに足場用梁をボイラ炉内に設置することができる足場用梁挿入装置の提案がなされている。例えば、ボイラ炉壁に形成した足場用梁入口部の前面に、足場用梁を挟持してボイラ炉内へ送り込む上下対の足場用梁送りローラをボイラ炉壁に対し前後方向に複数組配設するとともに、ボイラ炉壁の足場用梁入口部より上方に設けた設置口からボイラ炉内へ挿入しかつ先端にボイラ炉内足場用梁と係合可能な係合具が取付けられたワイヤを備えたワイヤ繰出し用ドラムを設けた装置がある（特許文献１参照）。
また、例えば、炉壁の前面に設置されるボイラ鉄骨に固定され、かつ足場用梁置き台から送り出された足場用梁を受け取りボイラ炉内へ送り出すよう足場用梁送りローラを複数本回転自在に備えた下側足場用梁挿入枠体と、足場用梁送りローラと上下に対をなし足場用梁を挟持した状態でボイラ炉内に送り出す足場用梁送りローラを複数本回転自在に備えた上側足場用梁挿入枠体とからなる装置がある（特許文献２参照）。
特開平５−５３５８号公報 実開平５−３４８１号公報 When assembling a scaffold for inspection in the boiler furnace, the operation of the boiler is stopped and the worker enters the boiler furnace after the temperature in the boiler furnace has dropped to a temperature at which operation can be performed in the boiler furnace. For this reason, a huge boiler operation stoppage time was required. Therefore, as a device for shortening the boiler shutdown time, the scaffold beam can be installed in the boiler furnace without waiting for the temperature to drop even if the temperature is too high for workers to enter the furnace. A beam insertion device has been proposed. For example, a plurality of pairs of upper and lower scaffolding beam feed rollers that sandwich the scaffolding beam and feed it into the boiler furnace on the front surface of the scaffolding beam entrance formed on the boiler furnace wall. In addition, a wire inserted into the boiler furnace from the installation port provided above the scaffold beam entrance portion of the boiler furnace wall and provided with an engagement tool attached to the boiler furnace scaffolding beam at the tip is provided. There is a device provided with a wire feeding drum (see Patent Document 1).
Also, for example, a plurality of scaffolding beam feed rollers can be rotated to receive a scaffolding beam that is fixed to a boiler steel frame installed on the front surface of the furnace wall and that is sent out from a scaffolding table for the scaffolding and sent out into the boiler furnace. The lower scaffolding beam insertion frame body and the scaffolding beam feeding roller that are paired up and down and the scaffolding beam feeding roller that feeds into the boiler furnace while sandwiching the scaffolding beam is provided on the upper side. There is an apparatus comprising a beam insertion frame for a scaffold (see Patent Document 2).

足場用梁挿入装置１０は、足場用梁挿入装置本体１１と、足場用梁挿入装置本体１１の上部に配置された２つの足場用梁支持部１２とを備えている。
足場用梁挿入装置本体１１は、ボイラ１の炉壁２に沿うようにボイラ１の外部の地面に敷設されたレール７上に設置されている。この足場用梁挿入装置本体１１の各隅角部には、レール７を把持してレール７上を走行可能な走行部１３が設けられている。 FIG. 2 is a diagram illustrating a schematic configuration of the scaffold beam insertion device 10. In addition, only the main components in the scaffold beam insertion device 10 are shown, and the other components are not shown.
The scaffolding beam insertion device 10 includes a scaffolding beam insertion device body 11 and two scaffolding beam support portions 12 disposed on the upper part of the scaffolding beam insertion device body 11.
The scaffold beam insertion device main body 11 is installed on a rail 7 laid on the ground outside the boiler 1 along the furnace wall 2 of the boiler 1. In each corner portion of the scaffold beam inserting apparatus main body 11, a traveling portion 13 is provided that can grip the rail 7 and travel on the rail 7.

また、これら２つの足場用梁支持部１２は、いずれも同形状であり、それぞれ２本の脚部１２ａ，１２ｂと梁部１２ｃとを有して門型に構成され、走行方向に対して平行となるように配置されている。それぞれの脚部１２ａ，１２ｂには、足場用梁４を両側から挟み込むように把持する把持部１４が設けられている。また、足場用梁挿入装置本体１１及び梁部１２ｃには、梁入口部３からボイラ１の内部に足場用梁４を送り出すローラ（送出部）１５が設けられている。なお、これら走行部１３、把持部１４及びローラ１５は、油圧モータを用いて駆動されている。ここで、走行部１３は、図示しないローラがレール７の上側及び下側からレール７を把持しており、それらローラを回転駆動することによって、レール７上をレール７に沿って走行可能となる。また、把持部１４は、足場用梁４に対して接近及び離間する方向に駆動する。また、ローラ１５は、足場用梁を送り出す方向に回転駆動する。これら走行部１３、把持部１４及びローラ１５を駆動するためのスイッチ１６は、足場用梁挿入装置本体１１に取付けられ、オペレータによって操作される。   The two scaffold beam supports 12 have the same shape, each having two leg portions 12a and 12b and a beam portion 12c, and are formed in a portal shape, and are parallel to the traveling direction. It is arranged to become. Each leg part 12a, 12b is provided with a gripping part 14 for gripping the scaffolding beam 4 from both sides. In addition, the scaffold beam insertion device main body 11 and the beam portion 12 c are provided with a roller (sending portion) 15 that feeds the scaffold beam 4 from the beam entrance portion 3 into the boiler 1. The traveling unit 13, the gripping unit 14, and the roller 15 are driven using a hydraulic motor. Here, the travel unit 13 is configured such that a roller (not shown) grips the rail 7 from the upper side and the lower side of the rail 7, and can travel along the rail 7 by rotating the rollers. . The gripping portion 14 is driven in a direction approaching and separating from the scaffold beam 4. Further, the roller 15 is rotationally driven in a direction in which the scaffold beam is sent out. A switch 16 for driving the traveling unit 13, the gripping unit 14, and the roller 15 is attached to the scaffolding beam insertion device body 11 and operated by an operator.

このような足場用梁挿入装置１０を用いて梁入口部３からボイラ１の内部に複数の足場用梁４を挿入する場合、足場用梁挿入装置１０は、梁入口部３ａの外側、すなわち正面で停止し、１本の足場用梁４を把持した後、１本の足場用梁４を送出して梁入口部３ａからボイラ１の内部に１本の足場用梁４を挿入し、足場用梁４の一部を梁出口部６ａから排出して足場用梁４を設置した後、レール７上を走行して梁入口部３ｂの正面まで移動して停止し、同様にして梁入口部３ｂからボイラ１の内部に１本の足場用梁４を設置する。このような工程を繰り返すことによって、梁入口部３からボイラ１の内部に複数の足場用梁４を設置する。すなわち、以下のような手順で複数の足場用梁４を設置する。   When a plurality of scaffolding beams 4 are inserted into the boiler 1 from the beam entrance 3 using such a scaffolding beam insertion device 10, the scaffolding beam insertion device 10 is located outside the beam entrance 3 a, that is, in front. After stopping and holding one scaffolding beam 4, one scaffolding beam 4 is sent out, and one scaffolding beam 4 is inserted into the boiler 1 from the beam entrance 3a. After a part of the beam 4 is discharged from the beam exit portion 6a and the scaffolding beam 4 is installed, the beam 4 travels on the rail 7 and moves to the front of the beam entrance portion 3b to stop, and similarly, the beam entrance portion 3b. From the above, one scaffolding beam 4 is installed inside the boiler 1. By repeating such a process, a plurality of scaffolding beams 4 are installed from the beam entrance 3 to the inside of the boiler 1. That is, a plurality of scaffolding beams 4 are installed in the following procedure.

まず、ボイラ１の炉壁２の最も左側に配置されている梁入口部３ａの正面まで足場用梁挿入装置１０が走行して停止する。そして、足場用梁４の一部である小梁４ａを運搬して足場用梁支持部１２内に挿入し、その小梁４ａを把持部１４で把持する。その後、小梁４ａの把持部１４での把持を解除して小梁４ａをローラ１５で炉壁２の梁入口部３ａの方向に送出する。
小梁４ａの一端が支持台８ａに支持されたとき、小梁４ａの送出を一時的に停止し、足場用梁４の一部である小梁４ｂを運搬して小梁４ａの他端に直列に接合する。小梁４ａと小梁４ｂとを接合した後、小梁４ｂを送出して小梁４ａの先端を梁入口部３ａに挿入する。 First, the scaffolding beam insertion device 10 travels to the front of the beam entrance 3a disposed on the leftmost side of the furnace wall 2 of the boiler 1 and stops. Then, the small beam 4 a which is a part of the scaffolding beam 4 is transported and inserted into the scaffolding beam support part 12, and the small beam 4 a is gripped by the gripping part 14. After that, the grip of the small beam 4a at the grip 14 is released, and the small beam 4a is sent by the roller 15 in the direction of the beam inlet 3a of the furnace wall 2.
When one end of the small beam 4a is supported by the support base 8a, the delivery of the small beam 4a is temporarily stopped, and the small beam 4b which is a part of the scaffolding beam 4 is transported to the other end of the small beam 4a. Join in series. After joining the small beam 4a and the small beam 4b, the small beam 4b is sent out, and the tip of the small beam 4a is inserted into the beam entrance 3a.

上記と同様にして小梁４ｂに小梁４ｃ，４ｄ，４ｅ，４ｆ，４ｇをそれぞれ直列に接合しながら、梁入口部３ａからボイラ１の内部にこれら小梁４ａ〜４ｇによって構成された１本の足場用梁４を挿入し、足場用梁４の一部、すなわち小梁４ａの先端を梁出口部６ａから排出して足場用梁４を設置する。このとき、小梁４ａの先端が支持台９ａに支持される。その後、小梁４ａを支持台９ａに固定し、小梁４ｆを支持台８ａに固定し、小梁４ｆと小梁４ｇとの接合を解除することで、梁入口部３ａに挿入された足場用梁４の設置が完了する。   In the same manner as described above, the small beams 4c, 4d, 4e, 4f, and 4g are joined in series to the small beam 4b, and one beam composed of the small beams 4a to 4g is formed inside the boiler 1 from the beam entrance portion 3a. The scaffold beam 4 is inserted, and a part of the scaffold beam 4, that is, the tip of the small beam 4 a is discharged from the beam exit portion 6 a to install the scaffold beam 4. At this time, the tip of the small beam 4a is supported by the support base 9a. Thereafter, the small beam 4a is fixed to the support base 9a, the small beam 4f is fixed to the support base 8a, and the joint between the small beam 4f and the small beam 4g is released, so that the scaffold is inserted into the beam entrance 3a. Installation of the beam 4 is completed.

梁入口部３ａに挿入された足場用梁４の設置が完了した後、梁入口部３ａの隣りに配置された梁入口部３ｂの正面まで足場用梁挿入装置１０が走行して停止する。そして、上記と同様の方法で、梁入口部３ｂに挿入された足場用梁４を設置する。
その後、足場用梁挿入装置１０が梁入口部３ｃ，３ｄ，３ｅ，３ｆそれぞれの正面に移動して、上記と同様の方法を繰り返すことで、梁入口部３ｃ，３ｄ，３ｅ，３ｆそれぞれに挿入された足場用梁４の設置が完了することとなる。 After the installation of the scaffolding beam 4 inserted into the beam entrance 3a is completed, the scaffolding beam insertion device 10 travels to the front of the beam entrance 3b arranged adjacent to the beam entrance 3a and stops. And the beam 4 for scaffolds inserted in the beam entrance part 3b is installed by the method similar to the above.
Thereafter, the scaffold beam insertion device 10 is moved to the front of each of the beam entrance portions 3c, 3d, 3e, and 3f, and is inserted into each of the beam entrance portions 3c, 3d, 3e, and 3f by repeating the same method as described above. The installation of the scaffold beam 4 is completed.

この場合、足場用梁４を把持部１４で把持しボイラ１の内部に挿入した後、足場用梁挿入装置１０が梁入口部３ａ〜３ｆのいずれか一つの正面に停止できるようボイラ１の外部に敷設されたレール７を走行できるため、足場用梁４を把持部１４で把持して梁入口部３ａから足場用梁４をボイラ１の内部に挿入する作業を１台の足場用梁挿入装置１０のみで順次行うことが可能となる。したがって、足場用梁挿入装置１０を設置する際の設置コスト、及びそれら足場用梁挿入装置１０をメンテナンスするためのメンテナンスコストを削減することができる。   In this case, after the scaffolding beam 4 is gripped by the gripping part 14 and inserted into the boiler 1, the scaffolding beam insertion device 10 can be stopped outside the boiler 1 so as to be stopped at any one of the beam entrance parts 3 a to 3 f. The scaffolding beam 4 is gripped by the gripping portion 14 and the scaffolding beam 4 is inserted into the boiler 1 from the beam entrance portion 3a. It becomes possible to carry out sequentially with only 10. Accordingly, it is possible to reduce the installation cost when installing the scaffold beam insertion device 10 and the maintenance cost for maintaining the scaffold beam insertion device 10.

また、足場用梁挿入装置１０がボイラ１の外部に敷設されたレール７上を走行することにより、足場用梁挿入装置１０の走行がレール７上で安定し、また、足場用梁挿入装置１０の走行に関する操作が容易となる。   Further, when the scaffold beam insertion device 10 travels on the rail 7 laid outside the boiler 1, the scaffold beam insertion device 10 travels on the rail 7, and the scaffold beam insertion device 10. This makes it easier to operate the vehicle.

なお、上記実施の形態において、梁入口部３ａ，３ｂ，３ｃ，３ｄ，３ｅ，３ｆの順に足場用梁４を挿入して設置することは、作業効率を向上させるという点で好ましいが、必ずしもこの順番で足場用梁４を挿入して設置することはない。足場用梁４を挿入して設置する順番を任意に変化させても、足場用梁挿入装置１０がレール７上を自由に移動できることで、上記実施の形態と同様、１台の足場用梁挿入装置１０のみで対応可能である。したがって、このような場合においても、足場用梁挿入装置１０の設置コスト及びメンテナンスコストの点において十分な効果が得られる。   In the above embodiment, it is preferable to insert and install the scaffolding beams 4 in the order of the beam entrance portions 3a, 3b, 3c, 3d, 3e, and 3f from the viewpoint of improving work efficiency. The scaffolding beams 4 are not inserted and installed in order. Even if the order of installing and installing the scaffolding beams 4 is arbitrarily changed, the scaffolding beam insertion device 10 can freely move on the rails 7, so that one scaffolding beam can be inserted as in the above embodiment. This can be handled only by the device 10. Therefore, even in such a case, a sufficient effect can be obtained in terms of installation cost and maintenance cost of the scaffold beam insertion device 10.

また、上記実施の形態において、足場用梁挿入装置１０は、ボイラ１の外部に敷設されたレール７上を走行するものでなくてもよい。すなわち、レール７が敷設されていない場合、ボイラ１の炉壁２に沿って走行可能な足場用梁挿入装置１０であれば、レール７上を走行する足場用梁挿入装置１０と同様の効果が得られる。   Moreover, in the said embodiment, the beam insertion apparatus 10 for scaffolds does not need to run on the rail 7 laid outside the boiler 1. FIG. That is, when the rail 7 is not laid, the scaffold beam insertion device 10 that can travel along the furnace wall 2 of the boiler 1 has the same effect as the scaffold beam insertion device 10 that travels on the rail 7. can get.
