Description

本発明は、発電設備内に装置されている電動機等の重量物を分解点検する際に、この電動機等の運搬に用いる発電設備内における重量物運搬装置に関する。   The present invention relates to a heavy material transport device in a power generation facility used for transporting the motor or the like when disassembling and inspecting a heavy material such as an electric motor installed in the power generation facility.

発電設備内において、例えば複数に並列しているオイルミストセパレータ換気ファン用電動機について分解点検する際に、この電動機のような重量物は、チェーンブロック等の器具を使用しないで人力で運搬している。このような電動機等を設置している個所の天井部には、梁、ビーム等がないため、チェーンブロック等の吊り上げ用の器具が使用できないからである。   In a power generation facility, for example, when overhauling a plurality of oil mist separator ventilation motors in parallel, heavy objects such as this motor are transported by human power without using a chain block or the like. . This is because there is no beam, beam or the like at the ceiling where such an electric motor or the like is installed, so that lifting equipment such as a chain block cannot be used.

このような電動機等の重量物を運搬する運搬器具に関する技術について、例えば特許文献１の特開平８−３２４９９２号公報「昇降架台を有するフロア運搬機」に示すように、昇降架台に沿ってガイドされる昇降送り台を備えており、昇降送り台を少なくとも１つのチェーン接続部材によって、実質的に鉛直方向の少なくとも１本の荷重チェーンに固定している形式のフロア運搬機において、荷重チェーンが少なくとも部分的に、少なくとも片側の開いたチェーンガイド内でガイドされている昇降架台を有するフロア運搬機が提案されている。
特開平８−３２４９９２号公報 As for a technique related to a transporting instrument for transporting such a heavy object such as an electric motor, for example, as shown in Japanese Patent Application Laid-Open No. 8-324992 “Floor transporter having a lifting platform” in Patent Document 1, it is guided along the lifting platform. In a floor transporter of the type having a lifting feed base that is fixed to at least one load chain in a substantially vertical direction by at least one chain connecting member, the load chain is at least partially In particular, floor conveyors have been proposed that have a lifting platform guided in an open chain guide on at least one side.
JP-A-8-324992

しかし、重量が約５０ｋｇはある電動機等の重量物について、狭い場所で作業者が人力により運搬することは大変に危険な作業になりやすいという問題を有していた。そこで、特許文献１のようなフロア運搬機を利用して運搬することが望ましいが、このフロア運搬機は、発電設備内のような狭い場所では利用できないことが多かった。   However, a heavy object such as an electric motor having a weight of about 50 kg has a problem that it is very dangerous for an operator to carry it by hand in a small place. Then, although it is desirable to carry using a floor carrier like patent document 1, this floor carrier could not be used in a narrow place like the inside of power generation equipment.

本発明は、かかる問題点を解決するために創案されたものである。すなわち、本発明の目的は、着脱式の吊上げ用の運搬器具を利用することで、天井部に梁、ビーム等がなく、フロア運搬機を走行させることができない狭い場所でも電動機等の重量物を安全かつ迅速に運搬できる発電設備内における電動機運搬装置を提供することにある。   The present invention has been developed to solve such problems. That is, the object of the present invention is to use a detachable lifting lifting device so that there is no beam, beam, etc. on the ceiling, and heavy objects such as an electric motor can be used even in a narrow place where the floor transporter cannot be run. An object of the present invention is to provide a motor transport device in a power generation facility that can be transported safely and quickly.

本発明の運搬装置は、発電設備内における電動機等の重量物（Ｈ）を吊り上げて運搬する重量物運搬装置（１）であって、前記重量物（Ｈ）を載置する架台（２）に取り付けた、横断面が四角形の筒状のポール支持部（３）と、上部に掛止リング（５）を有する吊りピース（６）を具備したポール（４）と、前記ポール（４）の下部は横断面が円形状の管に成り、該管内にベアリング（９）を取り付け、該ベアリング（９）に隣接して、上側の横断面が円形状で下側の横断面が四角形状に形成された連結軸（１０）の上側を、該ポール（４）の下部に軸周りに回動自在に挿入し、該ポール（４）の管から露出させた該連結軸（１０）の下側は、前記ポール支持部（３）に着脱自在に連結する構造に成る連結部（８）と、を備えた、ことを特徴とする。 The transport device according to the present invention is a heavy material transport device (1) for lifting and transporting a heavy object (H) such as an electric motor in a power generation facility, and is mounted on a gantry (2) on which the heavy object (H) is placed. A cylindrical pole support portion (3) having a rectangular cross section, a pole (4) having a suspension piece (6) having a retaining ring (5) at the top, and a lower portion of the pole (4) Has a circular cross section, and a bearing (9) is mounted in the pipe, and adjacent to the bearing (9), the upper cross section is circular and the lower cross section is formed in a square shape. The upper side of the connecting shaft (10) is inserted into the lower part of the pole (4) so as to be rotatable around the shaft, and the lower side of the connecting shaft (10) exposed from the tube of the pole (4) is connecting portion comprising a structure removably connected to the pole support (3) and (8), provided with, that characterized To.

前記吊りピース（６）は、前記ポール（４）上部において水平方向に前後動するように構成することが好ましい。
前記吊りピース（６）は、前記ポール（４）上部を中心にしてその掛止リング（５）側が円弧状に可動するように構成することができる。 The suspension piece (6) is preferably configured to move back and forth in the horizontal direction at the top of the pole (4).
The suspension piece (6) can be configured such that the retaining ring (5) side is movable in an arc shape around the top of the pole (4).

上記構成の発明では、天井部に梁、ビーム等がないような狭い発電設備内において、電動機等の重量物（Ｈ）を安全かつ迅速に運搬することができる。特に、ポール（４）は運搬作業時のみ設置する構造であり、複数台の重量物（Ｈ）の運搬に共用することができるため、設置コストを大幅に削減することができる。   In the invention with the above configuration, a heavy object (H) such as an electric motor can be transported safely and quickly in a narrow power generation facility where there are no beams, beams, or the like on the ceiling. In particular, the pole (4) has a structure that is installed only during transportation work, and can be shared for transportation of a plurality of heavy objects (H), so that the installation cost can be greatly reduced.

また、連結部（８）は、ポール（４）の下部の管内にベアリング（９）を取り付け、そのベアリング（９）に隣接して、連結軸（１０）の上側を軸周りに回動自在に挿入し、この連結軸（１０）の下側をポール支持部（３）に差し込んだ構造になるので、ポール（４）は吊りピース（６）と共に水平方向に回動させることができる。この連結軸（１０）の下側は、その横断面が四角形状になり、ポール支持部（３）も横断面が四角形の筒状になるため、連結軸（１０）の下側は回動しない。The connecting portion (8) has a bearing (9) mounted in a pipe below the pole (4), and the upper side of the connecting shaft (10) is rotatable around the axis adjacent to the bearing (9). Since it is inserted and the lower side of the connecting shaft (10) is inserted into the pole support (3), the pole (4) can be rotated in the horizontal direction together with the suspension piece (6). The lower side of the connecting shaft (10) has a quadrangular cross section, and the pole support (3) also has a quadrangular cylindrical shape, so the lower side of the connecting shaft (10) does not rotate. .

ポール（４）上部において水平方向に前後動するように構成した吊りピース（６）では、重量物（Ｈ）を吊り上げた後、ポール（４）と共に重量物（Ｈ）を水平方向に所定の位置に移動させることができる。即ち、重量物（Ｈ）を吊り上げた吊りピース（６）の移動半径の長さを可変できるので、重量物（Ｈ）を降ろす位置を微妙に調整することができる。   In the suspension piece (6) configured to move back and forth in the horizontal direction at the top of the pole (4), after lifting the heavy object (H), the heavy object (H) is placed in a predetermined position in the horizontal direction together with the pole (4). Can be moved to. That is, since the length of the moving radius of the suspension piece (6) that lifts the heavy object (H) can be varied, the position where the heavy object (H) is lowered can be finely adjusted.

同様に、ポール（４）上部を中心にしてその掛止リング（５）側が円弧状に可動するように構成した吊りピース（６）でも、重量物（Ｈ）を吊り上げた吊りピース（６）の移動半径の長さを可変できる。   Similarly, the suspension piece (6) configured such that the retaining ring (5) side is movable in an arc shape around the top of the pole (4) is also used for the suspension piece (6) that lifts the heavy object (H). The length of the moving radius can be varied.

更に、電動機等の重量物（Ｈ）について分解点検の際に取り付ける方法、即ちポール（４）を常設していないので、発電設備内のパトロールの際には、このポール（４）は外されており、歩行の邪魔にならない。 Furthermore , since a heavy object (H) such as an electric motor is attached at the time of overhaul and inspection, that is, the pole (4) is not permanently installed, the pawl (4) is removed during patrol in the power generation equipment. And does not interfere with walking.

本発明の発電設備内における重量物運搬装置は、電動機等の重量物を載置する架台と、架台に取り付けたポール支持部と、上部に掛止リングを有する吊りピースと、下部にポール支持部に着脱自在に連結される連結部をそれぞれ具備したポールとを備えた装置である。   The heavy-duty carrying device in the power generation facility of the present invention includes a gantry on which a heavy object such as an electric motor is placed, a pole support portion attached to the gantry, a suspension piece having a retaining ring at the upper portion, and a pole support portion at the lower portion. It is an apparatus provided with the pole which each provided with the connection part detachably connected to.

以下、本発明の好ましい実施の形態を図面を参照して説明する。
図１は実施例１の発電設備内における重量物運搬装置を示す正面図である。図２はポール支持部とポール連結部を示すものであり、（ａ）は縦断面図、（ｂ）はｂ−ｂ線断面図、（ｃ）はｃ−ｃ線断面図、（ｄ）はｄ−ｄ線断面図、（ｅ）はｅ−ｅ線断面図である。
実施例１の重量物運搬装置１は、発電設備内において、機器のケーシングＩに隣接する位置に電動機等の重量物Ｈを載置する架台２を配置し、この架台２にポール支持部３を取り付け、このポール支持部３に差し込んで重量物Ｈを吊り上げて運搬するポール４を備えた装置である。 Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a front view showing a heavy material transport device in the power generation facility of the first embodiment. FIG. 2 shows a pole support part and a pole connecting part, (a) is a longitudinal sectional view, (b) is a sectional view taken along the line bb, (c) is a sectional view taken along the line cc, and (d) is a sectional view. dd line sectional drawing, (e) is an ee line sectional view.
In the heavy load carrying device 1 according to the first embodiment, a stand 2 for placing a heavy load H such as an electric motor is disposed at a position adjacent to the casing I of the device in the power generation facility, and the pole support 3 is provided on the stand 2. It is an apparatus provided with a pole 4 that is attached and inserted into the pole support 3 to lift and carry a heavy object H.

架台２は、発電設備内において、例えば複数に並列しているオイルミストセパレータ換気ファン用電動機のような重量物Ｈを載置する台である。この架台２は図示したように単純に床面に箱状のものを置いただけでなく、ケーシングＩ側又は他の機器（図示していない）から溶接した鋼材を突設するようにしたものを用いることもできる。   The gantry 2 is a pedestal on which a heavy object H such as a plurality of oil mist separator ventilation fan motors arranged in parallel in the power generation facility is placed. As shown in the figure, the gantry 2 is not simply a box-like object placed on the floor surface, but a steel member welded from the casing I side or other equipment (not shown) is used. You can also.

ポール支持部３は、ポール４を支えるために架台２の脇に取り付けた略筒状の部材である。このポール支持部３は、架台２の脇に常設して取り付ける。但し、このポール支持部３が発電設備内において作業者がパトロールする際の通行の邪魔になるときは、架台２に着脱式に取り付けることも可能である。このポール支持部３は図示したように架台２の脇に床面に設置したものだけでなく、架台２の脇に強固に取り付けるものであれば、必ずしも床面から設置する必要はない。   The pole support portion 3 is a substantially cylindrical member attached to the side of the gantry 2 to support the pole 4. The pole support 3 is permanently installed on the side of the gantry 2 and attached. However, when this pole support part 3 obstructs the passage when an operator patrols in the power generation facility, it can be detachably attached to the gantry 2. The pole support 3 is not necessarily installed from the floor as long as it is firmly attached to the side of the pedestal 2 as well as the one installed on the floor at the side of the pedestal 2 as shown.

連結部８は、上部に掛止リング５を有する棒状の吊りピース６と、下部にポール支持部３に着脱自在に連結される連結部８をそれぞれ具備したものである。吊りピース６はその先の掛止リング５にチェーンブロック７等の吊り下げ具を掛け止め、重量物Ｈを吊り下げる部分である。   The connecting portion 8 includes a rod-shaped suspension piece 6 having a retaining ring 5 at the upper portion and a connecting portion 8 that is detachably connected to the pole support portion 3 at the lower portion. The suspension piece 6 is a portion that suspends a hanging tool such as a chain block 7 and the like, and suspends a heavy object H from the previous retaining ring 5.

連結部８は、ポール支持部３に差し込む部分である。これはポール４が発電設備内において作業者がパトロールする際の通行の邪魔にならないように、使用しないときにポール４を取り外せるようにするためでる。   The connecting portion 8 is a portion that is inserted into the pole support portion 3. This is because the pole 4 can be removed when not in use so that the pole 4 does not obstruct the passage when the operator patrols in the power generation facility.

また、連結部８は、図２に示すように、ポール４をポール支持部３に挿入した状態で、吊りピース６と共に水平方向に回動させる部材である。図示するように、ポール４の下部の管内に、ベアリング９を入れ、そのベアリング９に隣接して、断面が円形の連結軸１０を軸周りに回動自在に挿入し、この連結軸１０の下側は、ポール４から露出させ、その断面形状が四角形になっている。この連結軸１０の下側は、上述したポール支持部３の断面が四角形の筒内に着脱自在に嵌め込むようになっている。即ち、ポール支持部３は断面が四角形であるために、連結軸１０の下側は回動しない。   Further, as shown in FIG. 2, the connecting portion 8 is a member that rotates in the horizontal direction together with the suspension piece 6 in a state where the pole 4 is inserted into the pole support portion 3. As shown in the drawing, a bearing 9 is placed in a pipe below the pole 4, and a connecting shaft 10 having a circular cross section is inserted adjacent to the bearing 9 so as to be rotatable around the shaft. The side is exposed from the pole 4 and its cross-sectional shape is a quadrangle. The lower side of the connecting shaft 10 is configured such that the pole support 3 described above is detachably fitted into a square cylinder. That is, since the pole support portion 3 has a square cross section, the lower side of the connecting shaft 10 does not rotate.

この連結部８とポール支持部３は、水平方向にポール４が吊りピース６と共に回動するものであれば、このような構造に限定されない。また、この連結部８の回動機能をポール支持部３側に組み込んで、ポール４側は単に接続するだけにすることも可能である。   The connecting portion 8 and the pole support portion 3 are not limited to such a structure as long as the pole 4 rotates together with the suspension piece 6 in the horizontal direction. It is also possible to incorporate the turning function of the connecting portion 8 on the pole support portion 3 side and simply connect the pole 4 side.

このように構成した、このポール４の連結部８をポール支持部３に差し込んだ状態で、ポール４は吊りピース６と共に水平方向に回動させる。そこで、吊りピース６で重量物Ｈを吊り下げた状態で、このポール４の軸方向を回動中心にして、この重量物Ｈを回動して移動することができる。   With the connecting portion 8 of the pole 4 thus configured inserted into the pole support portion 3, the pole 4 is rotated together with the suspension piece 6 in the horizontal direction. Therefore, in a state where the heavy object H is suspended by the suspension piece 6, the heavy object H can be rotated and moved with the axial direction of the pole 4 as the rotation center.

図３は本発明の重量物運搬装置で電動機を運搬する方法を示す説明図であり、（ａ）はポールを取り付ける前の状態、（ｂ）はポールを取り付ける状態、（ｃ）は吊りピースにチェーンブロックを取り付ける状態、（ｄ）は重量物を吊り上げ、回動移動させる状態、（ｅ）は重量物を降ろす状態である。
本発明の運搬方法では、先ず、倉庫等の保管場所からポール４を取り出し、このポール４を分解点検する電動機等の重量物Ｈを載置する架台２まで運ぶ（図３（ａ））。
吊り上げて運搬する重量物Ｈの上方に、吊りピース６の掛止リング５が位置するように、ポール４の連結部８をポール支持部３に差し込む（図３（ｂ））。 3A and 3B are explanatory views showing a method of transporting an electric motor with the heavy article transport device of the present invention, in which FIG. 3A shows a state before the pole is attached, FIG. 3B shows a state where the pole is attached, and FIG. A state in which the chain block is attached, (d) is a state in which a heavy object is lifted and rotated, and (e) is a state in which the heavy object is lowered.
In the carrying method of the present invention, first, the pole 4 is taken out from a storage place such as a warehouse, and carried to the gantry 2 on which a heavy object H such as an electric motor for overhauling the pole 4 is placed (FIG. 3 (a)).
The connecting portion 8 of the pole 4 is inserted into the pole support portion 3 so that the retaining ring 5 of the suspension piece 6 is positioned above the heavy object H to be lifted and transported (FIG. 3B).

吊りピース６の掛止リング５にチェーンブロック７を引っ掛ける。このチェーンブロック７下端のフック１１を重量物Ｈに掛け止めて吊り上げる（図３（ｃ））。ポール４と共に重量物Ｈを水平方向に所定の位置に回動移動させる（図３（ｄ））。その位置においてその重量物Ｈを降ろす（図３（ｅ））。例えば台車１２に載せて別の場所へ運搬する。
最後に、ポール支持部３からポール４を抜き取り、保管場所に戻す。 The chain block 7 is hooked on the retaining ring 5 of the suspension piece 6. The hook 11 at the lower end of the chain block 7 is hung on the heavy object H (FIG. 3C). The heavy object H is rotated and moved to a predetermined position in the horizontal direction together with the pole 4 (FIG. 3D). The heavy object H is lowered at that position (FIG. 3 (e)). For example, it is placed on the carriage 12 and transported to another place.
Finally, the pole 4 is removed from the pole support 3 and returned to the storage location.

本発明は、天井部に梁、ビーム等がない狭い発電設備内において、重量物Ｈを安全かつ迅速に運搬することができる。特に、ポール４は作業時のみ設置することで、複数台の重量物Ｈの運搬に共用することができる。   The present invention can safely and quickly transport a heavy object H in a narrow power generation facility having no beam, beam or the like on the ceiling. In particular, the pole 4 can be shared only for transporting a plurality of heavy objects H by installing it only during work.

図４は吊りピースを可動し得る状態に構成した実施例２の重量物運搬装置を示す正面図であり、（ａ）は吊りピースに重量物を吊り下げる状態、（ｂ）は重量物を吊り下げた吊りピースを可動した状態である。
実施例２の重量物運搬装置１では、吊りピース６がポール４上部において水平方向に前後動するように構成した。例えば、重量物Ｈを降ろす場所がポール４から離れた位置にあるときに、この吊りピース６を可動して重量物Ｈを降ろす位置を微妙に調節することができる。逆に、重量物Ｈを降ろす場所がポール４に近いときも吊りピース６をポール４側に近づけるように可動する。 4A and 4B are front views showing the heavy article transporting apparatus according to the second embodiment configured to be able to move the suspension piece, where FIG. 4A is a state in which the heavy article is suspended from the suspension piece, and FIG. This is a state in which the suspended piece is moved.
In the heavy article transport device 1 of Example 2, the suspension piece 6 is configured to move back and forth in the horizontal direction at the top of the pole 4. For example, when the place where the heavy object H is lowered is at a position away from the pole 4, the position where the heavy object H is lowered can be finely adjusted by moving the suspension piece 6. On the contrary, even when the place where the heavy object H is lowered is close to the pole 4, the suspension piece 6 is movable so as to approach the pole 4 side.

実施例２の重量物運搬装置１は、ポール４の上部において、略Ｔ字形状に吊りピース６を組み付ける。この吊りピース６は垂直状態のポール４において水平方向に前後動するように構成する。この吊りピース６の長手方向にギヤ１３を形成し、このギヤ１３に噛合するギヤを、ハンドル１４の回動操作により、吊りピース６を直線方向に可動させる。   In the heavy material transport device 1 according to the second embodiment, the suspension piece 6 is assembled in a substantially T shape at the top of the pole 4. The suspension piece 6 is configured to move back and forth in the horizontal direction on the pole 4 in the vertical state. A gear 13 is formed in the longitudinal direction of the suspension piece 6, and the gear meshing with the gear 13 is moved in the linear direction by the turning operation of the handle 14.

図５は吊りピースを可動し得る状態に構成した実施例３の重量物運搬装置を示す正面図である。
実施例３の重量物運搬装置１では、吊りピース６がポール４上部を中心にしてその掛止リング５側が円弧状に可動するように構成した。例えば、ポール４の上部において、吊りピース６を略Ｌ字形状に組み付け、この吊りピース６の基端部に形成したギヤで角度を調整し得るように構成したものである。この実施例３の重量物運搬装置１でも、重量物Ｈを吊り上げた吊りピース６の半径の長さを可変することができる。 FIG. 5 is a front view showing the heavy-duty carrying device of Example 3 configured so that the suspension piece can be moved.
In the heavy article transport device 1 of Example 3, the suspension piece 6 is configured such that the side of the retaining ring 5 is movable in an arc shape around the top of the pole 4. For example, in the upper part of the pole 4, the suspension piece 6 is assembled in a substantially L shape, and the angle can be adjusted by a gear formed on the base end portion of the suspension piece 6. Also in the heavy material transport device 1 of the third embodiment, the length of the radius of the suspension piece 6 that lifts the heavy material H can be varied.

なお、本発明は、着脱式の吊上げ用のポール４を利用することで、天井部に梁、ビーム等がなく、フロア運搬機を走行させることができない狭い場所でも安全かつ迅速に電動機等の重量物Ｈを運搬できる構成であれば、上述した発明の実施の形態に限定されず、本発明の要旨を逸脱しない範囲で種々変更できることは勿論である。   The present invention uses the removable lifting pole 4 so that the weight of the electric motor or the like can be safely and quickly even in a narrow place where there is no beam, beam or the like on the ceiling and the floor transporter cannot be run. Of course, as long as the configuration can transport the product H, the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the scope of the present invention.

本発明の発電設備内における電動機運搬装置は、狭い空間であって重量物を運搬する際にも利用することができる。   The electric motor transport apparatus in the power generation facility of the present invention is a narrow space and can be used when transporting heavy objects.
