Description

本発明は、重量物を下段から上段へ揚重する揚重雇、及び、その揚重雇を用いた重量物の揚重運搬方法に関する。   The present invention relates to a lifting worker who lifts a heavy object from a lower stage to an upper stage, and a method for lifting and transporting a heavy article using the lifting person.

エレベーターのリニューアル工事時には、新しい巻上機や動力源等の重量物を機械室まで運搬・搬入し、古い巻上機や動力源等と交換する必要がある。この際、機械室までの通路に階段や段差がある場合は、重量物を持ち上げ階段や段差を乗り越えてから、機械室まで揚重・運搬する必要がある。   When renewing an elevator, it is necessary to transport and carry heavy objects such as new hoisting machines and power sources to the machine room and replace them with old hoisting machines and power sources. At this time, if there are stairs or steps in the passage to the machine room, it is necessary to lift the heavy object and get over the stairs or steps before lifting and transporting it to the machine room.

段差を超えて搬送物を搬送する搬送装置として、特許文献１に記載のものが知られている。この文献の要約書には、「搬送経路に段差がある場合でも、被搬送物を搬送できるようにする」ための搬送装置に関連して、「被搬送物を支持する複数の搬送物支持部と、搬送物支持部の夫々に、搬送物支持部を間に挟んで両側に配置され、搬送物支持部を支持して走行可能な一対の台車ユニットとを備える。各台車ユニットは、車輪部と伸縮可能な支柱部とを有する。一対の台車ユニットにおける一対の支柱部の上端を結ぶ直線は、鉛直方向から見て互いに交差するように配置されている。」との記載がある。   The thing of patent document 1 is known as a conveying apparatus which conveys a conveyed product over a level | step difference. In the abstract of this document, in relation to a transport device for “allowing transport of a transported object even when there is a step in the transport path”, “a plurality of transported object support units for supporting the transported object” And a pair of carriage units that are disposed on both sides of the carriage support section and can run while supporting the carriage support section. The straight lines connecting the upper ends of the pair of support columns in the pair of cart units are arranged so as to intersect each other when viewed from the vertical direction.

すなわち、特許文献１の搬送装置を用いることで、同文献の図４等に示されるように、揚重雇の形状に合致した張り出しがある場合には、重量物を張り出し部近傍に仮置きした上で、重量物を揚重している揚重雇を人力で移設しながら徐々に段差を乗り越えることができた。   That is, by using the transport device of Patent Document 1, as shown in FIG. 4 of the same document, when there is an overhang that matches the shape of lifting work, a heavy object is temporarily placed near the overhang portion. Above, I was able to get over the steps gradually while moving the lifting workers lifting heavy objects manually.

特開２０１５−１０１４１７号公報JP, 2015-101417, A

しかしながら、エレベーターの機械室近傍に設置された階段や段差の形状が、特許文献１の搬送装置に適した張り出し部状であるとは限らず、また、リニューアル工事時には機械室周辺の第三者の往来も多いため、重量物の搬送のためだけに、特許文献１の搬送装置に適した仮設の張り出し部を形成できるとも限らないため、特許文献１の搬送装置を、エレベーターのリニューアル工事時の重量物の揚重に採用するのは困難だった。   However, the shape of the steps and steps installed in the vicinity of the elevator's machine room is not necessarily the shape of an overhang suitable for the transport device of Patent Document 1, and the renovation work involves a third party around the machine room. Since there is a lot of traffic, it is not always possible to form a temporary overhanging part suitable for the transport apparatus of Patent Document 1 only for transporting heavy objects. Therefore, the transport apparatus of Patent Document 1 is weighted at the time of renewal work for an elevator. It was difficult to adopt for lifting goods.

そこで、本発明は、機械室近傍の階段や段差の形状によらず、重量物を下段側から上段側に揚重・運搬できる揚重雇、および、その揚重雇を用いた揚重運搬方法を提供することを目的とする。   Accordingly, the present invention relates to a lifting employer capable of lifting and transporting heavy objects from the lower stage side to the upper stage side regardless of the shape of the stairs and steps in the vicinity of the machine room, and a lifting and conveying method using the lifting employer. The purpose is to provide.

上記課題を解決するために、本発明に係る揚重雇は、重量物を下段側から上段側へ運搬するものであって、前記下段側に設置される略水平な第一レールと、該第一レールの一端を支持する第一支持具と、前記上段側に設置される略水平な第二レールと、該第二レールの一端を支持する第二支持具と、前記第一レールの他端と前記第二レールの他端を支持する、門型の第三支持具と、前記第一レール上を移動可能に設置される第一トロリと、前記第二レール上を移動可能に設置される第二トロリと、具備し、前記第一支持具の下端と前記第二支持具の下端の高さが異なるものとした。   In order to solve the above-mentioned problem, a lifting worker according to the present invention transports a heavy object from a lower stage side to an upper stage side, and includes a substantially horizontal first rail installed on the lower stage side, A first support for supporting one end of one rail; a substantially horizontal second rail installed on the upper side; a second support for supporting one end of the second rail; and the other end of the first rail And a gate-shaped third support that supports the other end of the second rail, a first trolley that is movably installed on the first rail, and a movably installed on the second rail. The second trolley includes a lower end of the first support and a lower end of the second support.

本発明の揚重雇、または、揚重方法によれば、階段や段差の形状によらず、重量物を下段側から上段側に揚重することができるため、例えば、これをエレベーターのリニューアル工事に用いれば、従来より能率良くリニューアル作業を行うことができる。   According to the lifting employment or lifting method of the present invention, a heavy object can be lifted from the lower stage side to the upper stage side regardless of the shape of the stairs or steps, for example, renewal work for an elevator. If used, the renewal work can be performed more efficiently than before.

図１は、重量物３０を階段の下段４０側から上段４１側へ移動させる際に用いられる、本発明の揚重雇１の一実施例を示す斜視図である。ここに示すように、揚重雇１は、階段の下段４０側に設置される主揚重雇１０と、階段の上段４１側に設置される追加揚重雇２０からなる。なお、重量物３０は、例えば、エレベーターのリニューアル工事時に更新される、巻上機、制御盤、油圧式パワーユニット等の機器であるが、以下では、重量物３０が箱状の新製油圧式パワーユニットである例を説明する。   FIG. 1 is a perspective view showing an embodiment of the heavy lifting 1 of the present invention used when moving a heavy article 30 from the lower stage 40 side to the upper stage 41 side of the stairs. As shown here, the lifter 1 includes a main lifter 10 installed on the lower stage 40 side of the stairs and an additional lifter 20 installed on the upper stage 41 side of the stairs. The heavy object 30 is a device such as a hoisting machine, a control panel, or a hydraulic power unit that is updated when the elevator is renewed. In the following description, the heavy object 30 is a box-shaped new hydraulic power unit. An example will be described.

図１に示すように、主揚重雇１０は、Ｈ型鋼材もしくはＩ型鋼材で構成された略水平なレール１１と、このレール１１の一端の支持具である門型構造体１２と、他端の支持具である門型構造体１３と、レール１１に設けられるトロリ１４と、このトロリ１４に連結され、重量物３０を揚重するチェーンブロック１５を有する。   As shown in FIG. 1, the main lifter 10 includes a substantially horizontal rail 11 made of H-type steel material or I-type steel material, a gate-type structure 12 that is a support at one end of the rail 11, and the like. It has a portal structure 13 which is an end support, a trolley 14 provided on the rail 11, and a chain block 15 which is connected to the trolley 14 and lifts a heavy object 30.

ここで、門型構造体１２は、略垂直な一対の支柱１２ａと、これらの頂部にボルト等で固定された略水平な梁１２ｂと、各支柱の下部に設置されるローラ１２ｃから構成されている。同様に、門型構造体１３も、略垂直な一対の支柱１３ａと、これらの頂部にボルト等で固定された略水平な梁１３ｂと、各支柱の下部に設置されるローラ１３ｃから構成されている。このような門型構造体１２、１３を梁同士が略平行となるように配置した後、レール１１の両端を梁１２ｂと梁１３ｂの夫々の中点にボルトまたはクリップで固定することで、レール１１、門型構造体１２、１３を一体化した、主揚重雇１０を構成する。   Here, the portal structure 12 is composed of a pair of substantially vertical support columns 12a, a substantially horizontal beam 12b fixed to the top of the support columns 12 with bolts or the like, and a roller 12c installed at the bottom of each support column.

Similarly, the gate-type structure 13 is also composed of a pair of substantially vertical columns 13a, a substantially horizontal beam 13b fixed to the top of these columns 13 with bolts, and a roller 13c installed at the bottom of each column. Yes. After arranging such gate-type structures 12 and 13 so that the beams are substantially parallel to each other, both ends of the rail 11 are fixed to the midpoints of the beams 12b and 13b with bolts or clips, so that the rail 11, the main lifting work 10 is formed by integrating the gate-type structures 12 and 13.

一方、追加揚重雇２０は、Ｈ型鋼材もしくはＩ型鋼材で構成された略水平な追加レール２１と、この追加レール２１の一端の支持具である追加門型構造体２２と、レール１１上に設けられた、追加レール２１の他端の支持具であるつなぎプレート２３と、追加レール２１に設けられる追加トロリ２４と、この追加トロリ２４に連結され、重量物３０を揚重する追加チェーンブロック２５を有する。   On the other hand, the additional lifter 20 includes a substantially horizontal additional rail 21 made of an H-type steel material or an I-type steel material, an additional portal structure 22 as a support at one end of the additional rail 21, and the rail 11 A connecting plate 23 that is a support at the other end of the additional rail 21, an additional trolley 24 provided on the additional rail 21, and an additional chain block that is connected to the additional trolley 24 and lifts the heavy load 30. 25.

ここで、追加門型構造体２２は、略垂直な一対の追加支柱２２ａと、これらの頂部にボルト等で固定された略水平な追加梁２２ｂと、各支柱の下部に設置される追加ローラ２２ｃから構成されている。そして、このような追加門型構造体２２を、追加梁２２ｂと梁１３ｂが略平行となるように配置した後、追加レール２１の両端を追加梁２２ｂの中点とつなぎプレート２３にボルトまたはクリップで固定することで、追加レール２１、追加門型構造体２２、つなぎプレート２３を一体化した、追加揚重雇２０を構成する。   Here, the additional gate-type structure 22 includes a pair of substantially vertical additional columns 22a, a substantially horizontal additional beam 22b fixed to the top of the columns with bolts, and an additional roller 22c installed at the lower part of each column. It is composed of Then, after arranging such an additional portal structure 22 so that the additional beam 22b and the beam 13b are substantially parallel, both ends of the additional rail 21 are bolted or clipped to the midpoint of the additional beam 22b and the connecting plate 23. As a result, the additional rail 21, the additional gate-type structure 22, and the connecting plate 23 are integrated to form the additional lifting worker 20.

なお、図１に例示した、各門型構造物の支柱１２ａ、１３ａ、追加支柱２２ａは、パイプサポート等を利用した伸縮可能なものである。また、梁１２ｂ、１３ｂ、追加梁２２ｂには角型鋼材を使用しているが、所望の強度を確保できれば、Ｈ型鋼材やＩ型鋼材のような他の形状のものを用いても良いし、アルミのような素材のものを用いても良い。   In addition, the support | pillars 12a and 13a of each portal type structure illustrated in FIG. 1, and the additional support | pillar 22a can be expanded-contracted using a pipe support.

以上の第１ステップ〜第７ステップを順次実行することにより、段差の形状に拘わらず、重量物３０を下段４０から上段４１に効率よく揚重・運搬することができる。   By sequentially executing the first to seventh steps described above, the heavy object 30 can be efficiently lifted and transported from the lower stage 40 to the upper stage 41 regardless of the shape of the step.

なお、以上では、重量物３０を下段４０から上段４１に運搬する方法を説明したが、重量物３０を上段４１から下段４０に運搬する際にも、本実施例の揚重雇１を利用することができる。この場合には、前述の第１ステップ〜第７ステップを逆の順序で実行すればよい。また、この場合には、主揚重雇１０を上段４１側に配置し、追加揚重雇２０を下段４０側に配置しても良い。   In the above description, the method for transporting the heavy article 30 from the lower stage 40 to the upper stage 41 has been described. However, when the heavy article 30 is transported from the upper stage 41 to the lower stage 40, the heavy lifting 1 of this embodiment is used. be able to. In this case, what is necessary is just to perform the above-mentioned 1st step-7th step in reverse order. In this case, the main lifting employer 10 may be arranged on the upper stage 41 side, and the additional lifting employer 20 may be arranged on the lower stage 40 side.

以上説明したように、本実施例に係る重量物の運搬及び揚重雇及び方法によれば、張り出しの有無によらず階段を経由して重量物３０の運搬を円滑に行うことができる。したがって、従来技術では困難であったエレベーターのリニューアル工事等にも適用でき、本実施例は従来技術に比べて優れた汎用性を確保することができる。また本実施例は、小型で比較的単純な構造の揚重雇１のみの構成で済むので、従来技術よりも簡単構成とすることができる。これにより本実施例は、従来技術に比べて施工工数及び施工費用を低減させることができる。   As described above, according to the heavy material transportation and lifting work and method according to the present embodiment, the heavy material 30 can be smoothly transported through the stairs regardless of the presence or absence of the overhang. Accordingly, the present invention can be applied to renovation work for an elevator, which has been difficult with the prior art, and this embodiment can ensure versatility superior to that of the prior art. In addition, since the present embodiment requires only the construction of the lifter 1 having a small and relatively simple structure, it can be made simpler than the prior art. Thereby, a present Example can reduce a construction man-hour and construction cost compared with a prior art.
