Description

本発明は、エンジン発電機に関し、詳しくは、大型のエンジン発電機に設けられる吊り耳の構造に関する。   The present invention relates to an engine generator, and more particularly, to the structure of a hanging ear provided on a large engine generator.

従来、重量のある大型のエンジン発電機では、搬入時にクレーン等で吊り上げて所定の位置まで移動させることから、ケーシングやフレームに、ロープを掛ける吊り耳を突設したものがあった。しかし、搬入後の作業時には、突出した吊り耳が邪魔になることがあり、また、屋内型のエンジン発電機で搬入口の寸法が狭い場合では、吊り耳が搬入口に当接することがあった。   Heretofore, in a large-sized engine generator having a heavy weight, since it is lifted by a crane or the like and moved to a predetermined position at the time of loading, there has been one in which a hanging ear for hanging a rope is protruded on a casing or a frame. However, at the time of work after loading, the protruding hanging ears may sometimes get in the way, and when the size of the loading opening is narrow in an indoor engine generator, the hanging ears may come in contact with the loading opening .

このため、エンジン発電機の補強フレームに吊り耳挿通孔を形成し、該吊り耳挿通孔に、両端にフランジ部を備えた円筒状の吊り耳を出没可能に配置し、搬入時には、吊り耳を突出させてロープを掛け、クレーン等で吊り上げ可能とし、搬入後は、吊り耳を補強フレーム内に押し込んで、吊り耳が突出しないようにしたものがあった（例えば、特許文献１参照。）。   For this reason, a hanging ear insertion hole is formed in the reinforcing frame of the engine generator, and a cylindrical hanging ear provided with flanges at both ends is disposed in the hanging ear insertion hole so as to be able to project and retract. There is a system in which the rope is made to project and be lifted by a crane or the like, and after carrying in, the hanging ear is pushed into the reinforcing frame so that the hanging ear does not protrude (for example, see Patent Document 1).

特開昭６２−９８６０６号公報Japanese Patent Application Laid-Open No. 62-98606

しかし、上述の特許文献１のものを大型のエンジン発電機に適用した際には、吊り耳の重量が嵩むことから、エンジン発電機をクレーン等で吊って所定の位置まで移動させた後、吊り耳を補強フレーム内に押し込む際に、吊り耳挿通孔内で吊り耳が傾き、作業者が吊り耳をスライドさせて吊り耳を補強フレーム内に押し込む作業に手間が掛かっていた。また、吊り耳がケーシング上部の補強フレームに設けられていることから、補強フレームを太くしなければならず、エンジン発電機の重量が増す虞があった。   However, when the thing of the above-mentioned patent documents 1 is applied to a large-sized engine generator, since the weight of a suspending ear increases, after suspending an engine generator with a crane etc. and making it move to a predetermined position, suspending When pushing the ear into the reinforcing frame, the hanging ear is inclined in the hanging ear insertion hole, and it takes time for the operator to slide the hanging ear to push the hanging ear into the reinforcement frame. In addition, since the hanging lugs are provided on the reinforcing frame at the top of the casing, the reinforcing frame must be thick, which may increase the weight of the engine generator.

そこで本発明は、搬入時には、突出した吊り耳にロープを掛けて吊り上げて所定位置まで移動させ、移動後には、吊り耳をエンジン発電機内に良好に収容させることができるエンジン発電機を提供することを目的としている。   Therefore, the present invention provides an engine generator capable of hanging a rope on a projecting hanging ear, lifting it up to a predetermined position at the time of loading, and moving the hanging ear into a good position in the engine generator after movement. It is an object.

上記目的を達成するため、本発明のエンジン発電機は、エンジンと該エンジンにより駆動される発電機とを搭載する床フレームの外面の複数箇所に、吊上げ用の吊り耳を出没可能に備えたエンジン発電機において、前記床フレームの外枠をチャンネル材で形成し、該チャンネル材のフランジ先端部間に補強板を固着し、該補強板と前記チャンネル材のウェブとに吊り耳挿通孔をそれぞれ設け、両吊り耳挿通孔間に水平方向の吊り耳ガイド筒を設け、前記吊り耳は、円柱部と、該円柱部の両端に設けられる第１固定板と第２固定板とを有し、前記円柱部は、軸線方向の長さが前記吊り耳ガイド筒の軸線方向の長さよりも長く、吊り耳ガイド筒内を移動可能な外径を有し、前記各固定板は、前記吊り耳挿通孔の内径より大きく、前記補強板及び前記ウェブより小さな外形を有し、前記吊り耳を補強板側から突出させたときには、前記第１固定板が、該第１固定板に設けられた第１ボルト挿通孔を介して挿通され、前記ウェブに設けられた第１雌ねじ孔に螺着する固定ボルトによってウェブの外面に固定され、前記吊り耳をウェブ側から突出させたときには、前記第２固定板が、該第２固定板に設けられた第２ボルト挿通孔を介して挿通され、前記補強板に設けられた第２雌ねじ孔に螺着する固定ボルトによって補強板の外面に固定されることを特徴としている。   In order to achieve the above object, the engine generator of the present invention is an engine provided with lifting ears for projecting and retracting at a plurality of locations on the outer surface of a floor frame on which an engine and a generator driven by the engine are mounted. In the generator, an outer frame of the floor frame is formed of a channel material, a reinforcing plate is fixed between the flanges of the channel material, and a hooking hole is provided in the reinforcing plate and the web of the channel material. A hanging ear guide cylinder in the horizontal direction is provided between the hanging ear insertion holes; the hanging ears have a cylindrical portion, and a first fixing plate and a second fixing plate provided at both ends of the cylindrical portion; The cylindrical portion has an outer diameter such that the axial length is longer than the axial length of the hanging ear guide cylinder and can move in the hanging ear guide cylinder, and each fixing plate has the hanging ear insertion hole Larger than the inner diameter of the The first fixing plate is inserted through the first bolt insertion hole provided in the first fixing plate when the hanging ear is made to project from the reinforcing plate side, and has an outer shape smaller than the web, and the web is formed. Is fixed to the outer surface of the web by a fixing bolt screwed into a first female screw hole provided in the second mounting plate, and the second fixing plate is provided on the second fixing plate when the hanging ear is projected from the web side It is characterized in that it is fixed to the outer surface of the reinforcing plate by a fixing bolt which is inserted through the second bolt insertion hole and screwed to a second female screw hole provided in the reinforcing plate.

また、前記固定ボルトは、前記第１固定板を前記ウェブの外面に固定するための固定ボルトと、前記第２固定板を前記補強板の外面に固定するための固定ボルトとに同じボルトを用いると好適である。   In addition, the fixing bolt uses the same bolt for fixing the first fixing plate to the outer surface of the web and for fixing the second fixing plate to the outer surface of the reinforcing plate. Is preferred.

本発明のエンジン発電機によれば、搬入時には、吊り耳の円柱部を吊り耳ガイド筒に沿って外側にスライドさせ、第１固定板とチャンネル材のウェブの外面とを当接させて第１挿通孔に挿通した固定ボルトを第１雌ねじ孔に締結して、ウェブに第１固定板を固定する。これにより吊り耳が外方に突出し、この吊り耳にロープを掛けてクレーン等で吊り上げてエンジン発電機を所定の場所に移動させることができる。また、吊り耳が強度のある床フレームに設けられていることから、床フレームを太くすることなく吊り耳を取り付けることができる。   According to the engine generator of the present invention, at the time of loading, the cylindrical portion of the hanging ear is slid outward along the hanging ear guide cylinder, and the first fixing plate is brought into contact with the outer surface of the web of the channel material. The fixing bolt inserted into the insertion hole is fastened to the first female screw hole to fix the first fixing plate to the web. As a result, the hooking ears protrude outward, and a rope can be hung on the hooking ears and lifted by a crane or the like to move the engine generator to a predetermined location. Further, since the hanging ears are provided on the strong floor frame, the hanging ears can be attached without thickening the floor frame.

エンジン発電機を所定の位置まで移動させた後には、第１雌ねじ孔及び第１挿通孔から固定ボルトを外し、吊り耳の円柱部を吊り耳ガイド筒に沿って床フレームの内側に向けてスライドさせ、第２固定板と補強板の外面とを当接させて第２挿通孔に挿通した固定ボルトを第２雌ねじ孔に締結して、補強板に第２固定板を固定する。これにより、吊り耳がエンジン発電機内に収容された状態となることから、エンジン発電機を搬入後に作業をする際に、吊り耳が邪魔になることがない。さらに、屋内型のエンジン発電機で搬入口の寸法が狭い場合でも、吊り耳をエンジン発電機内に収容した状態でコロ等を用いて屋内に良好に搬入させることができる。   After moving the engine generator to a predetermined position, remove the fixing bolt from the first female screw hole and the first insertion hole, slide the cylindrical part of the hanging ear toward the inside of the floor frame along the hanging ear guide cylinder The second fixing plate is brought into contact with the outer surface of the reinforcing plate, and the fixing bolt inserted into the second insertion hole is fastened to the second female screw hole to fix the second fixing plate to the reinforcing plate. As a result, since the hanging ears are accommodated in the engine generator, the hanging ears do not get in the way when carrying out the work after carrying in the engine generator. Furthermore, even when the size of the loading port is narrow in an indoor type engine generator, the hanging ears can be favorably carried indoors using a roller or the like in a state of being accommodated in the engine generator.

また、補強板とウェブとに設けた吊り耳挿通孔に、水平方向の吊り耳ガイド筒を設けたことから、吊り耳の円柱部が傾くことを防止でき、作業者は円柱部を容易にスライドさせることができ、作業性の向上を図ることができる。   In addition, since the hanging ear guide cylinder in the horizontal direction is provided in the hanging ear insertion hole provided in the reinforcing plate and the web, the cylindrical portion of the hanging ear can be prevented from tilting, and the operator slides the cylindrical portion easily. The work efficiency can be improved.

さらに、第１固定板をウェブの外面に固定するための固定ボルトと、第２固定板を補強板の外面に固定するための固定ボルトとに同じボルトを用いることにより、コストの削減を図ることができるとともに、固定ボルトを紛失する虞がない。   In addition, cost reduction can be achieved by using the same bolt for fixing the first fixing plate to the outer surface of the web and the fixing bolt for fixing the second fixing plate to the outer surface of the reinforcing plate. And there is no risk of losing the fixing bolt.
