Description

本発明は大型機械、設備装置などの重量物を所定位置に吊り下げ搬送する荷役搬送装置及びこれに使用する荷役搬送用吊具に係わり、大型機械を所定の搬送エリアから作業エリアに搬送し、この重量物を分解修理などの作業に適した状態で吊り下げ支持する揚重構造の改良に関する。   The present invention relates to a cargo handling device that hangs and conveys heavy objects such as large machines and equipment devices to a predetermined position, and a cargo handling lifting device used therefor, and conveys a large machine from a predetermined conveyance area to a work area. The present invention relates to an improvement in a lifting structure that supports a heavy object suspended in a state suitable for work such as overhauling.

一般に、大型重量物(以下「揚重物」という)を所定の作業エリアに搬送し、この作業エリアで分解・修理などの作業に適した姿勢で吊り下げ支持する揚重構造は、例えば天井クレーンなどとして広く知られている。このような天井クレーンは重量物を所定の搬入エリアから作業エリアに吊下げ搬送する装置として広く知られている。   In general, a lifting structure that transports a large heavy object (hereinafter referred to as “lifted object”) to a predetermined work area and suspends and supports it in a posture suitable for work such as disassembly and repair in this work area is, for example, an overhead crane It is widely known as. Such an overhead crane is widely known as a device for suspending and transporting heavy objects from a predetermined carry-in area to a work area.

例えば特許文献1には、工場などの建造物に左右一対のガーダを配置し、このガーダに横行レールを架橋し、この横行レールにトロリを装備して揚重物を吊り下げ搬送する揚重構造が開示されている。このように揚重物を走行レール方向と横行レール方向にX−Y両方向に移動する揚重構造は、揚重物を任意の位置から任意の位置に移動することが出来る特徴がある。また、工場その他の建造物の天井に走行レールを敷設して所定の搬送軌道を構成し、この軌道に沿って揚重物を吊り下げ搬送する設備装置も知られている。   For example, Patent Document 1 discloses a lifting structure in which a pair of left and right girder is arranged in a building such as a factory, a traverse rail is bridged to the girder, and a trolley is provided on the traverse rail to suspend and transport a lifted object. Is disclosed. In this way, the lifting structure that moves the lifted object in both the XY directions in the traveling rail direction and the traverse rail direction is characterized in that the lifted object can be moved from an arbitrary position to an arbitrary position. In addition, there is also known an equipment device that constructs a predetermined transport track by laying a traveling rail on the ceiling of a factory or other building and suspends and transports a lifted object along this track.

そしてこれらクレーンなどの揚重装置で重量物を搬送する場合には、例えば1基のクレーン装置で1つの重量物を搬入位置から作業位置に搬送し、その位置で所定の作業が終了した後、その重量物を搬出する。このような重量物の「搬入」、「作業(組立・分解など)」、「搬出」の一連の工程が終了した後、次の重量物を搬入する搬送方法が採られている。   And when transporting heavy objects with a lifting device such as a crane, for example, one heavy object is transported from the loading position to the work position with one crane apparatus, and after the predetermined work is completed at that position, Unload the heavy item. After such a series of steps of “carrying in”, “work (assembly / disassembly, etc.)” and “carrying out” of heavy objects is carried out, a conveying method for carrying in the next heavy object is adopted.

そこで、例えば工場などで複数の重量物を複数の作業エリアに搬入し、各作業エリアで所定の作業を並行して行う場合には、従来の天井クレーン構造を採用すると同一軌道或いは同一空間内で複数の重量物を移動しなければ成らず、その操縦が複雑で事故が発生する恐れがある。従って複数の作業エリアに同時に複数の重量物を搬出入する場合には作業エリア毎にそれぞれ搬出入口を設け、搬送用の天井クレーン或いはトレーラ軌道を配置している。
特開平5−186182号公報
Therefore, for example, when carrying a plurality of heavy objects into a plurality of work areas in a factory and performing predetermined work in parallel in each work area, if a conventional overhead crane structure is adopted, the same track or the same space is used. A plurality of heavy objects must be moved, and the maneuvering is complicated and an accident may occur. Accordingly, when a plurality of heavy objects are carried in and out of a plurality of work areas at the same time, a carry-in / out entrance is provided for each work area, and a transport overhead crane or trailer track is arranged.
JP-A-5-186182

上述のように、製造工場、修理工場などの建造物内に複数の作業エリアを配置し、各作業エリアで並行して製造或いは修理などの作業を行う場合には、従来は各作業エリアそれぞれに搬出入口を設け、重量物を搬送するクレーン、トレーラ軌道などの搬出入装置と、更に各作業エリアで重量物を吊り下げ支持する揚重設備を配置している。   As described above, when a plurality of work areas are arranged in a building such as a manufacturing factory or a repair factory and work such as manufacturing or repair is performed in parallel in each work area, each work area is conventionally A loading / unloading entrance is provided, and a loading / unloading device such as a crane and a trailer track for carrying heavy objects, and a lifting equipment for hanging and supporting heavy objects in each work area are arranged.

従って、設備スペースは製造或いは分解修理などの作業に要するスペースと重量物の搬出入に要するスペースが必要で膨大なものとなる。更に各作業エリアに搬出入装置(クレーン或いはトレーラ軌道)と重量物を吊り下げ支持する揚重設備が必要となり設備費用も膨大なものとなる問題があった。   Therefore, the equipment space is enormous and requires a space required for operations such as manufacturing or disassembly and repair and a space required for carrying in and out heavy objects. In addition, there is a problem in that each work area requires a loading / unloading device (crane or trailer track) and a lifting equipment for suspending and supporting heavy objects, resulting in a huge equipment cost.

そこで本発明者は所定の搬入エリアから複数の作業エリアに重量物を搬送分配し、各作業エリアに配置した懸吊用の懸架部材に掛け替え懸吊することによって作業エリア毎に搬出入口と搬出入装置(クレーン設備など)を設ける必要がないとの知見に至った。この場合に作業エリアでは所定の搬送軌道に沿って移送された揚重物をこの軌道を挟んで左右2方向から牽引部材で安定した姿勢で懸吊する必要が生ずる。   Therefore, the present inventor transports and distributes heavy objects from a predetermined carry-in area to a plurality of work areas, and hangs and hangs on a suspension member for suspension arranged in each work area. It came to the knowledge that it was not necessary to install equipment (crane equipment etc.). In this case, in the work area, it is necessary to suspend the lifted material transferred along a predetermined conveyance track from the left and right directions with a pulling member in a stable posture across the track.

そこで本発明者は、揚重物を懸吊する吊り天秤部材を互いに分離可能に結合した第1、第2の吊り天秤部材で構成し、この両部材を結合した状態で揚重物を搬入エリアから作業エリアに搬入し、作業エリアで2つの天秤部材の一方を懸架部材に懸吊した後、これを分離することによって掛け替え懸吊することを案出し、先に特願2007−051864号として特許出願した。   Therefore, the present inventor configured the first and second suspension balance members that are separably coupled to each other to suspend the lifted material, and the lifted material is brought into the carry-in area in a state in which both members are coupled. And then suspending one of the two balance members on the suspension member in the work area, and then separating the two balance members to devise the suspension, and patented as Japanese Patent Application No. 2007-051864. I applied.

このように着脱自在の2つの吊り天秤部材を1セットとして揚重物の搬送(結合状態)と作業エリアでの懸吊(分離状態)に使い分けると広い工場設備内に天秤部材が散乱し、第1第2のセット状態が乱れて混乱することがある。   Thus, when two detachable lifting balance members are used as a set for transporting the lifted material (combined state) and hanging in the work area (separated state), the balance member is scattered in a wide factory facility. 1 The second set state may be confused and confused.

そこで本発明者は、作業エリアで揚重物を2方向から安定して懸吊する際に、これを吊り下げ支持する吊り天秤構造を、搬送軌道を横切るように伸縮自在又は回動自在に構成して軌道を挟んで反対側に位置する懸架部材に連結することによって搬送軌道の両側2方向から揚重物を掛け替え懸吊することが可能との着想に至った。   Therefore, the present inventor configures a lifting balance structure that suspends and supports a lifted object from two directions in a work area so that it can be extended and retracted or rotated so as to cross the conveyance track. Then, by connecting to a suspension member located on the opposite side across the track, the idea has been reached that it is possible to change and hang a lifted object from two directions on both sides of the transfer track.

更に、本発明者はこの場合に作業エリアで搬送軌道の左右2方向から揚重物を支持する部材と、揚重物を吊下げ搬送する部材を分離して離脱可能に連結することにより、作業エリアから揚重物を搬出する際にその作業が容易であるとの着想に至った。   Further, in this case, the present inventor separated the member supporting the lifted material from the left and right directions of the transport track and the member hanging and transporting the lifted material in the work area so as to be detachable. I came up with the idea that the work is easy when unloading lifted goods from the area.

本発明は所定の搬送軌道に沿って作業エリアに搬出入する揚重物を、この作業エリアで2方向から安定して掛け替え懸吊することが可能であり、同時にその掛け替え作業が容易で安全である荷役搬送用吊具の提供をその主な課題としている。
更に本発明は、作業エリアに搬入された揚重物を安定した2方向から作業レールに吊り換え支持すると共に揚重物をこの作業エリアから搬出する際に搬送レールに容易に吊り換えることが可能な荷役搬送用吊具の提供をその課題としている。
According to the present invention, it is possible to stably hang and lift a lifted object that is carried into and out of a work area along a predetermined transport path from the two directions in this work area, and at the same time, the work of changing is easy and safe. The main issue is the provision of a lifting device for cargo handling.
Furthermore, the present invention can support the lifted material carried in the work area by suspending and supporting the work rail from two stable directions and easily suspending the lifted material from the work area to the transport rail. The objective is to provide a proper lifting device for cargo handling.

上記課題を達成するため本発明は、揚重物を所定の搬出入エリアから複数の作業エリアに搬送する際に、各作業エリアに搬送軌道を挟んで少なくとも一対の懸架部材を対向配置する。そして揚重物を吊り下げ支持する吊り天秤部材を、第1第2の懸架部材間に架橋支持する架橋部材と、揚重物を吊下げ支持する懸吊部材で構成する。そして架橋部材は、その基端部を第1懸架部材に先端部が搬送軌道を横切るように摺動自在又は回動自在に支持すると共にその先端部を上記搬送軌道の反対側に位置する第2懸架部材に着脱可能に連結支持する。そこでこの架橋部材に懸吊部材を離脱(分離)可能に連結し、これに揚重物を連結支持する吊下げ連結部と、巻上機に連結する吊上げ連結部を設ける。以下その具体的構成について説明する。   In order to achieve the above object, according to the present invention, when a lifted object is transported from a predetermined carry-in / out area to a plurality of work areas, at least a pair of suspension members are opposed to each work area with a transport track therebetween. And the suspension balance member that suspends and supports the lifted material is constituted by a bridging member that bridges and supports the first and second suspension members, and a suspension member that supports and supports the lifted material. The bridging member supports the base end of the bridging member on the first suspension member so that the front end of the bridging member is slidable or pivotable so as to cross the transport track, and the second end is positioned on the opposite side of the transport track. The suspension member is detachably connected and supported. Therefore, a suspension member is connected to the bridging member so that the suspension member can be detached (separated), and a suspension connection portion for connecting and supporting a lifted material and a lifting connection portion for connecting to a hoisting machine are provided. The specific configuration will be described below.

所定の搬送軌道に沿って搬入された揚重物を作業エリアで掛け替え懸吊する荷役搬送用吊具であって、上記搬送軌道を挟んで対向配置された少なくとも一対の第1、第2懸架部材(30、35)と、この第1、第2懸架部材間に架橋支持される吊り天秤部材(40)(40)とを備える。上記吊り天秤部材(40)は、上記第1、第2懸架部材間に架橋支持される架橋部材(40A)と、揚重物を吊下げ支持する懸吊部材(40B)とで構成する。この架橋部材(40A)は、その基端部を上記第1懸架部材に先端部が上記搬送軌道を横切るように摺動自在又は回動自在に支持すると共に、その先端部を上記搬送軌道の反対側に位置する上記第2懸架部材に着脱可能に連結支持する。また上記懸吊部材(40B)には架橋部材(40A)に離脱可能に連結され、上記揚重物を連結支持する吊下げ連結部と、巻上げ機に連結する吊上げ連結部を設ける。   A cargo handling and lifting device for hanging and lifting a lifted object carried along a predetermined transfer track in a work area, wherein at least a pair of first and second suspension members disposed opposite to each other across the transfer track.

Each of the flange surface and the joint surface is provided with a projecting member on one side and a fitting recess that fits the projecting member on the other side, and the lifting connection portion of the suspension member (40B) is lifted upward to provide a flange. The connection between the surface and the fitting recess is released.

上記第1懸架部材(30)には、搬送軌道(20)と略々直交する方向にガイドレール(32g)を設け、上記第2懸架部材には、架橋部材(40A)の先端部を連結支持する連結支持部を設ける。そして架橋部材(40A)は、その基端部(40a)に上記ガイドレール(32g)に摺動自在に係合するトロリ部材(41a、41b)が、その先端部(40b)に連結支持部に係脱可能に係合する先端連結部(42)をそれぞれ設ける。   The first suspension member (30) is provided with a guide rail (32g) in a direction substantially perpendicular to the conveyance track (20), and the distal end portion of the bridging member (40A) is connected and supported to the second suspension member. A connecting support portion is provided.

A tip connecting portion (42) that is detachably engaged is provided.

所定の搬入エリア(A)から作業エリア(B)に揚重物を吊り下げ搬送する搬送レール(20L)と、搬送レールに走行移動可能に装架された走行トロリ(21)と、作業エリア(B)に配置され、搬送レール(20L)を挟んで対向配置された少なくとも一対の第1、第2の懸架部材(30、35)と、この第1、第2懸架部材間に架橋支持され、搬送レールに沿って移送された揚重物を掛け替え懸吊する吊り天秤部材(40)とを備える。そして上記吊り天秤部材(40)は、上記第1、第2懸架部材間に架橋支持される架橋部材(40A)と、揚重物を吊下げ支持する懸吊部材(40B)とで構成する。この架橋部材(40A)は、その基端部(40a)を第1懸架部材(30)に先端部(40b)が搬送レール(20L)を横切るように摺動自在又は回動自在に支持すると共に、その先端部を上記搬送軌道の反対側に位置する上記第2懸架部材(35)に着脱可能に連結支持する。上記懸吊部材(40B)は、上記架橋部材(40A)に離脱可能に連結し、これに揚重物を連結支持する吊下げ連結部(40d)と、巻上げ機(35)に連結する吊上げ連結部(40e)を設ける。   A transport rail (20L) for suspending and transporting a lifted object from a predetermined carry-in area (A) to a work area (B), a travel trolley (21) mounted on the transport rail so as to travel, and a work area ( B) and at least a pair of first and second suspension members (30, 35) disposed opposite to each other with the conveyance rail (20L) interposed therebetween, and are bridged and supported between the first and second suspension members, And a lifting balance member (40) for hanging and hanging the lifted material transferred along the transport rail. The suspension balance member (40) is composed of a bridging member (40A) that is bridge-supported between the first and second suspension members and a suspension member (40B) that suspends and supports the lifted material. The bridging member (40A) supports the base end portion (40a) on the first suspension member (30) so that the tip end portion (40b) crosses the transport rail (20L) so as to be slidable or rotatable. The tip portion is detachably connected to and supported by the second suspension member (35) located on the opposite side of the transport track. The suspension member (40B) is releasably connected to the bridging member (40A), and a suspension connection portion (40d) for connecting and supporting a lifted object to the bridge member (40A), and a lifting connection for connecting to a hoisting machine (35). A part (40e) is provided.

本発明は、揚重物を吊り下げ支持する吊り天秤部材を架橋部材と懸吊部材とで構成し、作業エリアに揚重物を搬入する搬送軌道を挟んで対向配置された一対の懸架部材の一方に、架橋部材の基端部を摺動可能又は回動可能に支持し、その先端部は搬送軌道を横切って反対側に位置する懸架部材に連結支持し、この架橋部材に離脱可能に連結した懸吊部材に揚重物を吊下げ支持する吊下げ連結部と、巻き上げ機に連結する吊上げ連結部を設けたものであるから次の顕著な効果を奏する。   According to the present invention, a suspension balance member that suspends and supports a lifted object is composed of a bridging member and a suspension member, and a pair of suspension members that are arranged to face each other across a conveyance track for carrying the lifted object into a work area. On the other hand, the base end of the bridging member is supported so as to be slidable or pivotable, and the distal end of the bridging member is connected to and supported by a suspension member located on the opposite side across the conveying track, and is detachably connected to the bridging member. Since the suspension connecting member is provided with the suspension connecting portion for hanging and supporting the lifted material and the lifting connection portion for connecting to the hoisting machine, the following remarkable effects can be obtained.

揚重物を搬送軌道に沿って所定の作業エリアに搬入する際は、架橋部材をこの軌道の一側部に位置する第1懸架部材に格納して(軌道から)退避させ、搬入後にこの架橋部材を摺動又は回動することによって先端部を、軌道を横切って反対側に位置する第2懸架部材に連結支持し、この状態で架橋部材に連結した懸吊部材に揚重物を(搬送軌道の)走行トロリから掛け替え懸吊することとなる。従って吊り天秤部材(架橋部材と懸吊部材)は作業エリアで搬送軌道の側部に退避した位置に格納され、揚重物の搬入後には軌道の左右2方向から揚重物を吊り下げ支持するため、大型大重量の揚重物を作業エリアで作業に適した個所を安定した姿勢で2方向から吊り下げ支持することが可能となる。   When a lifted object is carried into a predetermined work area along the conveyance track, the bridging member is stored in the first suspension member located on one side of the track and retracted (from the track). By sliding or rotating the member, the tip end portion is connected and supported to the second suspension member located on the opposite side across the track, and in this state the lifted material is transported to the suspension member connected to the bridging member (conveyance) It will be suspended from the traveling trolley. Therefore, the suspension balance member (the bridging member and the suspension member) is stored in the working area at a position retracted to the side of the conveyance track, and after the lifted material is loaded, the lifted material is suspended and supported from the left and right directions of the track. Therefore, it is possible to suspend and support a large and heavy weight lifted object from two directions in a stable posture in a work area.

更に本発明は、架橋部材と懸吊部材を着脱自在に連結するに際に、架橋部材に設けたフランジ面(載置面)に懸吊部材に設けた接合面を載置支持し、その一方に突起を、他方に嵌合凹部(孔又は溝)を設けることによって懸吊部材を巻上げ機などで吊上げると架橋部材から懸吊部材を切り離すことが可能となる。従って例えば作業エリアで作業レールに吊下げ支持している揚重物を搬送レールに簡単に吊り換えることが可能となり、搬送レールに沿って他の作業エリアに移送することが可能となる。この場合に作業エリアで揚重物を吊り換える必要がなくその作業が至って容易となる。   Further, in the present invention, when the bridging member and the suspension member are detachably connected, the joint surface provided on the suspension member is placed and supported on the flange surface (mounting surface) provided on the bridging member. When the suspension member is lifted by a hoisting machine or the like by providing a protrusion on the other side and a fitting recess (hole or groove) on the other side, the suspension member can be separated from the bridging member. Therefore, for example, the lifted object supported by the work rail in the work area can be easily suspended by the transport rail, and can be transferred to another work area along the transport rail. In this case, there is no need to hang the lifted material in the work area, and the work is facilitated.

このように本発明は揚重物を特定の搬入エリアから搬送軌道に沿って複数の作業エリアに分配搬送し、各作業エリアに配置された吊り天秤部材に吊り換え支持することが可能となり、作業エリアの省スペース化と同時に工場など建造物の敷地面積を効率的に活用することが可能となる。   As described above, the present invention enables the lifted material to be distributed and transported from a specific carry-in area to a plurality of work areas along the transport track, and can be suspended and supported by a suspension balance member arranged in each work area. It is possible to efficiently use the site area of buildings such as factories as well as space saving.

更に本発明は、複数の作業エリアでそれぞれ揚重物を吊り下げ支持する吊り天秤部材(架橋部材と懸吊部材)は、各作業エリアの天井部に配置された懸架部材に格納され、揚重物の搬出入の妨げとならず、搬入後には軌道を挟む2方向から揚重物を吊り下げ支持するため、吊り天秤部材が工場内に散乱することがない。   Further, according to the present invention, a lifting balance member (a bridging member and a suspension member) for supporting a lifted object in a plurality of work areas is stored in a suspension member disposed on a ceiling portion of each work area. It does not hinder the loading and unloading of objects, and after loading, the lifted objects are suspended and supported from two directions across the track, so that the lifting balance member is not scattered in the factory.

FIG. 1 shows the layout of a production factory that produces large heavy goods or a repair factory that disassembles, repairs, and maintains large heavy goods. The illustrated layout configuration includes one (or more than one) carry-in / out area A at a predetermined position of the building 10, and the lifted goods W carried from the carry-in / out area A are arranged in a plurality of work areas B. It is characterized by being distributed and conveyed. For this reason, the conveyance track | orbit 20 for conveying the lifting material W from the carrying in / out area A to several work area B1, B2, B3, B4, such as 1st work area B1 and 2nd work area B2, is arrange | positioned. The transport track 20 is composed of a transport rail 20L extending from the entrance / exit end 20a to the transport end 20b of each work area. The transport rail 20L is, for example, a section I-shaped steel and is laid on a solid beam such as the ceiling of the building 10. And the lift W is conveyed by the traveling trolley 21 (the structure will be described later) mounted on the conveyance rail 20L.

尚本発明にあって、搬出入エリアAから作業エリアBに所定の搬送軌道20に沿って揚重物Wを搬送するための搬送機構は、搬送レール20Lに嵌合した走行車輪を有する走行トロリ(例えばクラブトロリなど)21で構成する(レール搬送機構)か、或いは建造物10の天井に左右一対の走行レールを敷設し、この走行レールに架橋支持したガータを設け、このガーダに形成した横行レールに走行トロリを装架して揚重物WをY−Y方向に吊り下げ移送する天井クレーン機構であっても良い。以下前者のレール搬送機構について本発明を説明する。   In the present invention, the transport mechanism for transporting the lift W along the predetermined transport track 20 from the carry-in / out area A to the work area B has a travel trolley having travel wheels fitted to the transport rail 20L. (For example, a club trolley) 21 (rail transport mechanism) or a pair of left and right traveling rails laid on the ceiling of the building 10, and a girder supported by bridging on the traveling rails. It may be an overhead crane mechanism in which a traveling trolley is mounted on a rail and the lifted article W is suspended and transferred in the YY direction. The present invention will be described below with respect to the former rail transport mechanism.

[荷役搬送装置の構成]
本発明の荷役搬送装置は、建造物10の搬出入エリアAと作業エリアBとの間に敷設された搬送レール20Lと、この搬送レール20Lに装架された走行トロリ21と、この走行トロリ21に搭載された巻上機23と、各作業エリアBに敷設された一対の懸架部材30、35と、この一対の懸架部材30、35間に架橋支持される吊り天秤部材(以下「吊り天秤組」という)40とから構成される。更に吊り天秤組40は架橋部材40Aと懸吊部材40Bとで構成される。上記走行トロリ21と巻上機23の構成については後述する。
[Configuration of cargo handling equipment]
The cargo handling and conveying apparatus of the present invention includes a conveying rail 20L laid between a carry-in / out area A and a work area B of a building 10, a traveling trolley 21 mounted on the conveying rail 20L, and the traveling trolley 21. , A pair of suspension members 30 and 35 laid in each work area B, and a suspension balance member (hereinafter referred to as a “suspending balance assembly”) supported by bridging between the pair of suspension members 30 and 35. 40). Further, the suspension balance set 40 is composed of a bridging member 40A and a suspension member 40B. The configuration of the traveling trolley 21 and the hoisting machine 23 will be described later.

そこで上記懸架部材30、35は搬送レール20Lに沿って吊り下げ搬送された揚重物Wを作業エリアBで吊り換え支持する為に各作業エリアに少なくとも一対装備(図示のものは4対)する。つまり揚重物Wはその重心位置が搬送軌道20の略々直下に位置するように上述の走行トロリ21で吊下げ搬送される。そこでこの揚重物Wを、搬送軌道20を挟んで左右2方向から懸吊することによって安定した姿勢が得られ、同時にその吊り換え作業も安全となる。このため図3に示すように第1の懸架部材(以下「第1懸架部材」という)30は軌道20の右側に、第2の懸架部材(以下「第2懸架部材」という)35は軌道左側に左右一対をなすように配置されている。   Therefore, the suspension members 30 and 35 are equipped with at least one pair in each work area (four pairs shown in the figure) in order to suspend and support the lifted material W suspended and transported along the transport rail 20L in the work area B. . That is, the lifted article W is suspended and conveyed by the traveling trolley 21 so that the position of the center of gravity is located almost directly below the conveyance track 20. Therefore, a stable posture can be obtained by suspending the lifted object W from the left and right directions with the conveyance track 20 interposed therebetween, and at the same time, the suspending operation is also safe. Therefore, as shown in FIG. 3, the first suspension member (hereinafter referred to as “first suspension member”) 30 is on the right side of the track 20, and the second suspension member (hereinafter referred to as “second suspension member”) 35 is on the left side of the track. Are arranged in a pair.

この第1、第2懸架部材30、35は建造物10の天井などに固定した梁状部材で構成しても良いが、図示のものは図2Y−Y方向(揚重物の長手方向)に敷設した固定レール(以下「作業レール」という)31、36に走行トロリ32、37で位置移動可能に装架してある。これは左右一対の懸架部材30、35の位置(吊下げ位置)を揚重物Wに付設されている牽引フックWfに位置合わせする為と、吊下げ後の揚重物WをY−Y方向に位置移動するためである。従って揚重物Wを吊下げ後に位置移動する必要のない場合には懸架部材30、35を建造物10の天井などに固定(固定構造)して設置しても良い。   The first and second suspension members 30 and 35 may be constituted by beam-like members fixed to the ceiling of the building 10 or the like, but the illustrated one is in the YY direction (longitudinal direction of the lifted object) in FIG. The fixed rails (hereinafter referred to as “working rails”) 31 and 36 are installed so as to be movable by traveling trolleys 32 and 37. This is because the position of the pair of left and right suspension members 30, 35 (hanging position) is aligned with the tow hook Wf attached to the lifted object W, and the lifted object W after being suspended is in the Y-Y direction. This is to move the position. Therefore, when it is not necessary to move the position of the lift W after suspending, the suspension members 30 and 35 may be fixed (fixed structure) to the ceiling of the building 10 or the like.

上記作業レール31、36は各作業エリアB1、B2、B3、B4に搬送軌道20を挟んで右側に作業レール31a、31bが、左側に作業レール36a、36bが所定の間隔を隔てて敷設されている(図1及び図3参照)。この作業レール31、36は搬送軌道20と略々並行で、そのレール長さは作業エリアBでの作業に適した長さに形成する。この右側作業レール31a、31bに第1懸架部材30が走行トロリ32a、32bで装架され、左側作業レール36に第2懸架部材35が走行トロリ37a、37bで装架されている。   The work rails 31 and 36 have work rails 31a and 31b on the right side and work rails 36a and 36b on the left side of the work areas B1, B2, B3, and B4 with the transport track 20 interposed therebetween at a predetermined interval. (See FIGS. 1 and 3). The work rails 31 and 36 are substantially parallel to the transport track 20, and the rail length is formed to a length suitable for work in the work area B. A first suspension member 30 is mounted on the right work rails 31a and 31b by travel trolleys 32a and 32b, and a second suspension member 35 is mounted on the left work rail 36 by travel trolleys 37a and 37b.

このように第1懸架部材30と第2懸架部材35とは、搬送軌道20を挟んで軌道スパンSLを形成して左右対向配置されている。この懸架部材30、35と上記作業レール31、36は適宜断面形状のビーム鋼で形成され、揚重物Wの重量を支えるように堅牢に建造物10の天井などに設置されている。そしてこの第1第2懸架部材30、35間に架橋支持した下記の吊り天秤組40で揚重物Wを吊り下げ支持する。   As described above, the first suspension member 30 and the second suspension member 35 are disposed opposite to each other while forming the track span SL across the transport track 20. The suspension members 30 and 35 and the work rails 31 and 36 are appropriately formed of beam steel having a cross-sectional shape, and are firmly installed on the ceiling of the building 10 so as to support the weight of the lifted article W. The lift W is suspended and supported by the following suspended balance set 40 supported by bridge between the first and second suspension members 30 and 35.

[Configuration of cross-linked member]
As described above, the bridging member 401A is made of beam steel longer than the track span SL, and the base end portion 40a thereof is supported by the first suspension member 30 so as to be slidable (or rotatable). FIG. 4 shows the connection support structure. In the figure, the first suspension member 30 is integrally provided with a guide rail (I-shaped steel lower end flange portion) 32g longer than the track span SL, and the base end portion 40a of the bridging member 40A is provided on the first trolley. 41a and the second trolley 41b are slidably fitted and supported. In the first and second trolleys 41a and 41b, the respective wheels 41r are fitted and supported by the rail 30g, and are coupled to the base end portion 40a of the bridging member 40A. The first trolley 41a is provided with an adjuster spring and a positioning bolt for the height position adjusting mechanism 41e. This is for the purpose of adapting the height positions of the first and second trolleys 41a and 41b to the guide rail 32g, and it may be arranged on either the first or second trolley.

上述のように第1懸架部材30に摺動自在に装架した架橋部材40Aには、これを位置決めロックするロック機構33と、懸架部材30に沿って摺動移動する駆動操作機構34が備えられている。ロック機構33は上述の第2トロリ41bに設けたストッパ(折曲げ片)33aと、これに係脱自在に歯合するロック爪33bと、このロック爪33bを付勢する付勢バネ(不図示)とで構成されている。このロック爪33bは第1懸架部材30に揺動(回動)自在に軸支持され、第2トロリに設けられたストッパ33a(第1トロリに設けても良い)に係合することによって架橋部材40Aをその位置に係止ロックする。そしてこのロック爪33bは架橋部材40Aの先端部40bが搬送軌道20から退避した格納位置でストッパ33aと係合する位置に配置されている。   As described above, the bridging member 40A slidably mounted on the first suspension member 30 is provided with a lock mechanism 33 that positions and locks the bridge member 40A, and a drive operation mechanism 34 that slides and moves along the suspension member 30. ing. The lock mechanism 33 includes a stopper (bending piece) 33a provided on the second trolley 41b, a lock claw 33b that is detachably engaged with the stopper, and a biasing spring (not shown) that biases the lock claw 33b. ) And.

Lock 40A into position. The lock claw 33b is disposed at a position where the distal end portion 40b of the bridging member 40A engages with the stopper 33a at the retracted position where it is retracted from the conveyance track 20.

また、上記ロック爪33bにはストッパ33aとの係合を解除する操作ワイヤ33cが連結されハンドルレバー33d(図3参照)を握ることによってロック爪33bがストッパ33aから離脱するようになっている。従って第1懸架部材30に摺動自在に装備された架橋部材40Aは搬送軌道20から退避した格納位置(図3の状態)でロック機構33によって係止され、ハンドル操作でロック解除してこれを摺動すると先端部40bが軌道20を横切って第2懸架部材35側に移動することとなる。この位置(吊り位置)では先端部40bが第2懸架部材35に連結されることによってその位置に保持される(図5の状態)。   Further, the lock claw 33b is connected with an operation wire 33c for releasing the engagement with the stopper 33a, and the lock claw 33b is detached from the stopper 33a by grasping the handle lever 33d (see FIG. 3). Accordingly, the bridging member 40A slidably mounted on the first suspension member 30 is locked by the lock mechanism 33 in the retracted position (state shown in FIG. 3) retracted from the transport track 20, and unlocked by operating the handle. If it slides, the front-end | tip part 40b will move to the 2nd suspension member 35 side across the track 20. At this position (hanging position), the tip end portion 40b is connected to the second suspension member 35 to be held at that position (state shown in FIG. 5).

上記駆動機構34は架橋部材40Aを第1懸架部材30のガイドレール32gに沿って図4左右方向に移動するように構成される。図示のものは第1懸架部材30に滑車34aが設けられ、この滑車34aとオペレータの操作位置との間に操作紐(ワイヤ、チェンなど)34bが掛け渡してある。そして操作紐34bは第1トロリ41aのフレームに固定ボルト34cで連結され、ループ状の操作紐の引っ張り方向によってトロリを図4左右いずれかの方向に移動するように構成されている。   The drive mechanism 34 is configured to move the bridging member 40A in the left-right direction in FIG. 4 along the guide rail 32g of the first suspension member 30. In the illustrated example, a pulley 34a is provided on the first suspension member 30, and an operation string (wire, chain, etc.) 34b is stretched between the pulley 34a and the operation position of the operator. The operation string 34b is connected to the frame of the first trolley 41a by a fixing bolt 34c, and is configured to move the trolley in either the left or right direction in FIG. 4 depending on the pulling direction of the loop-shaped operation string.

図5は架橋部材40Aの先端部40bを第2懸架部材35に連結した状態を示す。架橋部材40Aの先端部40bには先端ジョイント機構42が設けられ、第2懸架部材35にはジョイント受け機構38が設けられ、それぞれが着脱自在に連結及び離脱するように構成されている。先端ジョイント機構42はクランプ部材42aと、結合扞42bと着脱操作レバー42cで構成されている。またジョイント受け機構38は嵌合部38aと、ロック爪38bとインデックスプランジャ38cとで構成されている。   FIG. 5 shows a state in which the distal end portion 40 b of the bridging member 40 </ b> A is connected to the second suspension member 35. A distal end joint mechanism 42 is provided at the distal end portion 40b of the bridging member 40A, and a joint receiving mechanism 38 is provided at the second suspension member 35, which are configured to be detachably connected and detached. The tip joint mechanism 42 includes a clamp member 42a, a coupling rod 42b, and an attaching / detaching operation lever 42c. The joint receiving mechanism 38 includes a fitting portion 38a, a lock claw 38b, and an index plunger 38c.

上記先端ジョイント機構42は、連結扞42bの一端を架橋部材40Aの先端部に着脱自在に結合し、この連結扞42bの他端部を第2懸架部材35のジョイント受け機構38に着脱自在に連結するように構成されている。つまり図6(b)に示すように連結扞42bには上下端部に連結孔42x、42yが設けられ、その下端連結孔42xに天秤部材40のクランプピン42zが嵌合し、上端連結孔42yに第2懸架部材35の嵌合部38aが嵌合するようになっている。   The tip joint mechanism 42 removably couples one end of the connecting rod 42b to the tip of the bridging member 40A and removably connects the other end of the connecting rod 42b to the joint receiving mechanism 38 of the second suspension member 35. Is configured to do. That is, as shown in FIG. 6B, the connection rod 42b is provided with connection holes 42x and 42y at the upper and lower ends, and the clamp pin 42z of the balance member 40 is fitted into the lower connection hole 42x, and the upper connection hole 42y. The fitting portion 38a of the second suspension member 35 is fitted to the second suspension member 35.

つまり架橋部材40Aの先端部40bには連結用のブラケット42qが溶接などで一体成形され、このブラケット42qに連結扞42bの下端部を挿入する係合凹部が設けられている。そして架橋部材40Aの先端部にはブラケット42qと連結扞42bの連結孔42xを貫通するクランプピン42zが互いを連結するように設けられている。尚、この連結扞42bをクランクピン42zで着脱する構成を図示するが、連結扞42bは架橋部材40Aの先端部に溶接などで一体に形成しても良い。   That is, the connecting bracket 42q is integrally formed by welding or the like at the distal end portion 40b of the bridging member 40A, and an engaging recess for inserting the lower end portion of the connecting rod 42b is provided in the bracket 42q. And the clamp pin 42z which penetrates the bracket 42q and the connection hole 42x of the connection rod 42b is provided in the front-end | tip part of bridge | crosslinking member 40A so that it may mutually connect. In addition, although the structure which attaches and detaches this connecting rod 42b with the crank pin 42z is illustrated, the connecting rod 42b may be integrally formed by welding or the like at the distal end portion of the bridging member 40A.

一方、第2懸架部材35のジョイント受け機構38は、上述の連結扞42bの上端連結孔42yが嵌合する嵌合部38aで構成されている。この嵌合部38aには図6(b)に示すように上端連結孔42yの嵌合を案内する傾斜ガイド面38xが設けられている。また、第2懸架部材35には、ロック爪38bが連結扞42bを係止ロックするように揺動自在に配置されている。このロック爪38bには、図示しない付勢バネで図6(b)矢示方向に付勢され、このバネに抗して矢示反対方向に退避する傾斜カム面38yが設けられている。従って、連結扞42bがガイド面38xに沿って進入する際には、その上端縁がロック爪38bの傾斜カム面38yに係合し、このロック爪38bは上方に押し上げて退避する。そして互いに嵌合した後は、付勢バネ(不図示)で同図矢印方向に揺動して連結扞42bの上端部を係止ロックすることとなる。尚図示38cはインデックスプランジャであり、ロック爪38bと協働して連結扞42bの位置を規制する。上記ロック爪38bには、操作紐39が連結され、この操作紐39先端のレバー39rを操作することによってロック爪38bの係止を解除するようになっている。   On the other hand, the joint receiving mechanism 38 of the second suspension member 35 includes a fitting portion 38a into which the upper end connecting hole 42y of the connecting rod 42b described above is fitted. As shown in FIG. 6B, the fitting portion 38a is provided with an inclined guide surface 38x for guiding the fitting of the upper end connecting hole 42y. In addition, a lock claw 38b is swingably disposed on the second suspension member 35 so as to lock and lock the connecting rod 42b. The lock claw 38b is provided with an inclined cam surface 38y that is urged in a direction indicated by an arrow in FIG. 6B by an urging spring (not shown) and retracts in a direction opposite to the arrow against the spring. Therefore, when the connecting rod 42b enters along the guide surface 38x, the upper end edge of the connecting rod 42b engages with the inclined cam surface 38y of the lock claw 38b, and the lock claw 38b is pushed upward and retracted. Then, after being fitted to each other, the urging spring (not shown) swings in the direction of the arrow in the figure to lock the upper end of the connecting rod 42b. Incidentally, an index plunger 38c shown in the figure regulates the position of the connecting rod 42b in cooperation with the lock claw 38b. An operation string 39 is connected to the lock claw 38b, and the lock claw 38b is unlocked by operating a lever 39r at the tip of the operation string 39.

A lifting connection portion 40e that is connected to the hoisting machine 23 and a suspension connection portion 40d that supports the lifting object W in a suspended manner are provided. A pair of hanging connecting portions 40d shown in the figure are formed at two left and right locations, and a lifting connecting portion 40e is integrally formed at the center. The suspended connecting portion 40d is configured by a connecting hole as in the first embodiment, and a lifting member (chain, wire, etc.) is hooked on the connecting hole to support the lifted article W. . The lifting connection portion 40e is integrated with the central portion of the suspension member 40B by welding or the like in an inverted T shape. The connecting member 40x is provided with a joint surface 40y. And the connection hole connected with the winding machine 23 is provided in the upper end part of the connection member 40, and the hanging connection part is comprised by this connection hole.

上記接合面40yは架橋部材40Aの上面フランジ40fに載置支持され、第1実施形態と同様に構成されている。この上面フランジ40fと接合面40yには一方に位置決め用の突起40tが、他方にこれと適合する嵌合凹部40uが設けられている。そしてこの突起40tと嵌合凹部40uとは鉛直方向に嵌合及び離脱するように形成されている。   The joint surface 40y is placed and supported on the upper surface flange 40f of the bridging member 40A, and is configured in the same manner as in the first embodiment. The upper surface flange 40f and the joint surface 40y are provided with a positioning projection 40t on one side and a fitting recess 40u adapted to the other side. The protrusion 40t and the fitting recess 40u are formed so as to be fitted and detached in the vertical direction.

[第3実施形態]
また、図9に示す懸吊部材40Bは、前述の架橋部材40Aに連結される縦長鋼で構成されている。つまり略々水平方向に配置された架橋部材40Aに対してこの懸架部材40Bは垂直方向に連結される。この懸吊部材40Bには前述のものと同様に揚重物Wを吊下げ支持する吊下げ連結部40dと吊上げ連結部40eが、それぞれシャックルなどを掛け止めする連結孔で形成されている。
[Third Embodiment]
Moreover, the suspension member 40B shown in FIG. 9 is comprised by the vertically long steel connected with the above-mentioned bridge | crosslinking member 40A. That is, the suspension member 40B is connected in the vertical direction with respect to the bridging member 40A arranged substantially in the horizontal direction. In the suspension member 40B, a suspension connection portion 40d and a suspension connection portion 40e for suspending and supporting the lifted object W are formed in the suspension members 40B as connection holes for retaining shackles and the like, respectively.

図示の吊下げ連結部40dは懸吊部材40Bの下端部に1個所設けられ、揚重物Wを1点で吊り下げ支持するように構成されている。そして懸吊部材40Bの上端部には巻上げ機23に連結する連結孔が設けられ、この連結孔で吊上げ連結部40eが構成されている。また懸吊部材40Bには接合面40yが前述の第1、第2実施形態と同様に設けられ、この接合面40yで架橋部材40Aの上面フランジ40fに載置支持されるようになっている。この上面フランジ40fと接合面40yには一方に位置決め用の突起40tが、他方にこれと適合する嵌合凹部40uが設けられている。そしてこの突起40tと嵌合凹部40uとは鉛直方向に嵌合及び離脱するように形成されている。   The illustrated suspension connecting portion 40d is provided at one position on the lower end of the suspension member 40B, and is configured to suspend and support the lifted object W at one point. And the connection hole connected with the hoisting machine 23 is provided in the upper end part of the suspension member 40B, and the lifting connection part 40e is comprised by this connection hole. The suspension member 40B is provided with a joint surface 40y in the same manner as in the first and second embodiments described above. The joint surface 40y is placed and supported on the upper surface flange 40f of the bridging member 40A. The upper surface flange 40f and the joint surface 40y are provided with a positioning projection 40t on one side and a fitting recess 40u adapted to the other side. The protrusion 40t and the fitting recess 40u are formed so as to be fitted and detached in the vertical direction.

従って上記第1乃至第3、いずれの実施形態においても、揚重物Wは懸吊部材40Bに吊下げ支持され、この懸吊部材40Bは上記架橋部材40Aを介して第1第2の懸架部材30、35に支持される。そして各懸吊部材40Bの吊上げ連結部40eを巻上げ機23に連結して上方に吊上げれば懸吊部材40Bは架橋部材40Aから離脱し、揚重物Wを他の作業エリアB或いは搬出入エリアAに搬送することが可能となる。   Therefore, in any of the first to third embodiments, the lifted object W is suspended and supported by the suspension member 40B, and the suspension member 40B is supported by the first and second suspension members via the bridging member 40A. 30 and 35. Then, if the lifting connection portion 40e of each suspension member 40B is connected to the hoisting machine 23 and lifted upward, the suspension member 40B is detached from the bridging member 40A, and the lifted material W is moved to another work area B or a carry-in / out area. A can be conveyed to A.

そこで、この揚重物Wを支持した懸吊部材40Bを巻上げ機23で上方に吊上げて架橋部材40Aから分離するとき上述の懸吊部材40Bでは次の問題が起きる。例えば架橋部材40Aをビーム鋼で構成し、懸吊部材40Bを断面コの字状の鋼材で構成すると吊下げ連結部40dの上縁部Hが架橋部材40Aの下縁部Jと衝合することとなる。そこで作業者が巻上げ機(不図示)の操作を誤って切り離し高さLより過剰に吊上げると架橋部材40Aの下縁部Jを持ち上げる。このとき架橋部材40Aが前述の第2懸架部材35に連結されているため、その連結部を破損する恐れがある。   Therefore, when the suspension member 40B supporting the lifted object W is lifted upward by the hoisting machine 23 and separated from the bridging member 40A, the above-described suspension member 40B has the following problem. For example, when the bridging member 40A is made of beam steel and the suspension member 40B is made of a steel material having a U-shaped cross section, the upper edge H of the suspension coupling portion 40d abuts the lower edge J of the bridging member 40A. It becomes. Therefore, when the operator accidentally cuts off the operation of the hoisting machine (not shown) and lifts it excessively from the height L, the lower edge portion J of the bridging member 40A is lifted. At this time, since the bridging member 40A is connected to the second suspension member 35 described above, the connecting portion may be damaged.

このような懸吊部材40Bの切り離しの際に、上述の連結部の破損を防ぐため、図10(b)に示す装置は、架橋部材40Aの下縁部Jと懸吊部材40Bの上縁部Hのいずれか一方に傾斜面(緩衝面)kを形成してある。これと同時に架橋部材40Aは図示矢印a方向に揺動するように第2架橋部材40A、40Bにピン連結してある。このような構造を採用することにより、懸吊部材40Bを誤って過剰に吊上げても同図(c)に示すように傾斜面kの作用で懸吊部材40Bは矢印b方向に、また架橋部材40Aは矢印a方向に、互いに逃げる方向に揺動することとなる。この傾斜面kによる衝合で吊り下げ部材40や巻上機23等に過負荷がかかることがない。   In order to prevent breakage of the above-described connecting portion when such a suspension member 40B is separated, the apparatus shown in FIG. 10B includes a lower edge portion J of the bridging member 40A and an upper edge portion of the suspension member 40B. An inclined surface (buffer surface) k is formed on either one of H. At the same time, the bridging member 40A is pin-coupled to the second bridging members 40A and 40B so as to swing in the direction of the arrow a. By adopting such a structure, even if the suspension member 40B is accidentally lifted excessively, the suspension member 40B is moved in the direction of the arrow b by the action of the inclined surface k as shown in FIG. 40A swings in the direction of the arrow a so as to escape from each other. The collision by the inclined surface k does not overload the suspension member 40, the hoisting machine 23, and the like.

[搬送レールのトロリ構造]
次に搬送レール20Lに揚重物Mを吊り下げ支持するクレーン構造について説明する。
図11に示すように、上述の搬送レール20Lは例えば断面I型鋼などでレール面20r、20qが設けられている。そこでこの搬送レール20Lに沿って揚重物Mを吊り下げた状態で走行するトロリ21が装架される。この走行トロリ21としては種々の構造が知られているが図示のものは断面I型形状の搬送レール20Lのレール面20r、20qに装架された自走式トロリを示す。
[Conveyor rail trolley structure]
Next, a crane structure that suspends and supports the lift M on the transport rail 20L will be described.
As shown in FIG. 11, the above-described transport rail 20 </ b> L is made of, for example, I-section steel and has rail surfaces 20 r and 20 q. Therefore, a trolley 21 that travels with the lifted object M suspended along the transport rail 20L is mounted. Although various structures are known as the traveling trolley 21, the illustrated one shows a self-propelled trolley mounted on the rail surfaces 20r and 20q of the conveying rail 20L having an I-shaped cross section.

上記走行トロリ21は、ユニットフレーム26に一対の走行輪27a、27b及び27c、27dがそれぞれ回転軸に回動自在に軸受け支持され、この走行輪27a、27bがレール面20rに、走行輪27c、27dがレール面20qに係合支持されるようになっている。つまりユニットフレーム26はI型レール(搬送レール)を挟むように断面U字状に構成され、このユニットフレーム26の対向側壁にそれぞれ走行輪27a、27b及び27c、27dが軸受け支持されている。そしてユニットフレーム26には走行モータMO1が搭載され、この走行モータMO1は走行輪27aの回転軸を駆動回転するようになっている。尚、図示24a、24bは左右一対のガイドコロであり搬送レール20Lのレール側面に係合して摺動回転するように上記ユニットフレーム26に軸支持されている。図示24cは電装ボックスである。従って走行トロリ21は搬送レール20Lに走行輪27a、27b及び27c、27dで装架され、走行モータMO1でレール面20r、20qに沿って自走することなる。そして上記ユニットフレーム26には揚重物Mを吊り下げ支持する巻上げ機23が連結扞23jを介して連結されている。   In the traveling trolley 21, a pair of traveling wheels 27a, 27b, 27c, and 27d are rotatably supported on a rotating shaft on a unit frame 26, and the traveling wheels 27a and 27b are supported on a rail surface 20r and traveling wheels 27c, 27d is engaged and supported by the rail surface 20q. That is, the unit frame 26 has a U-shaped cross section so as to sandwich the I-shaped rail (conveying rail), and the running wheels 27a, 27b and 27c, 27d are supported by bearings on the opposite side walls of the unit frame 26, respectively. A traveling motor MO1 is mounted on the unit frame 26, and the traveling motor MO1 drives and rotates the rotation shaft of the traveling wheel 27a. 24a and 24b shown in the figure are a pair of left and right guide rollers, which are axially supported by the unit frame 26 so as to engage with the rail side surface of the transport rail 20L and rotate. 24c shown is an electrical equipment box. Accordingly, the traveling trolley 21 is mounted on the transport rail 20L by the traveling wheels 27a, 27b, 27c, and 27d, and travels along the rail surfaces 20r and 20q by the traveling motor MO1. The unit frame 26 is connected to a hoisting machine 23 for suspending and supporting the lift M through a connecting rod 23j.

[巻上機の構成]
上記巻上機23は、通常のホイストで構成されている。図11に示すようにこの巻き上げ機23はユニットフレーム23Uに軸承した駆動回転軸23x(不図示)にロードシーブ23rが設けられ、この駆動回転軸23xに減速歯車を介して巻上げモータMO2を連結して構成し、図示しないブレーキ、リミットスイッチなどが内蔵されている。そしてユニットフレーム23Uは、その上方を前記走行トロリ21に連結してあり、上記ロードシーブ23rにはロードチェーン25が歯合してある。従って巻上げモータMO2を正逆転することによって駆動回転軸23x(不図示)が正逆転し、これに取付けたロードシーブ23rに歯合されたロードチェーン25が上下動することとなる。そこでロードチェーン25の下端部にはフック25fが連結され、後述する吊り天秤部材40を掛け止め支持する。
[Configuration of hoisting machine]
The hoisting machine 23 is composed of a normal hoist. As shown in FIG. 11, in the hoisting machine 23, a load sheave 23r is provided on a drive rotating shaft 23x (not shown) supported by a unit frame 23U, and a hoisting motor MO2 is connected to the driving rotating shaft 23x via a reduction gear. Built-in brakes, limit switches, etc. (not shown). The unit frame 23U is connected to the traveling trolley 21 at an upper portion thereof, and a load chain 25 is engaged with the load sheave 23r. Accordingly, when the hoisting motor MO2 is rotated forward and backward, the drive rotary shaft 23x (not shown) is rotated forward and backward, and the load chain 25 engaged with the load sheave 23r attached thereto moves up and down. Therefore, a hook 25f is connected to the lower end portion of the load chain 25, and a hanging balance member 40 described later is latched and supported.

[荷役搬送装置の作用]
次に上述の荷役搬送装置及び吊具の作用について「揚重物の搬出入」「揚重物の吊り換え」「揚重物の分解・組立」「揚重物の転送」の順に説明する。
[Operation of cargo handling equipment]
Next, the operations of the above-described cargo handling device and the hanging tool will be described in the order of “carrying in / out of the lifted object”, “replacement of the lifted object”, “disassembling / assembling the lifted object”, and “transfer of the lifted object”.

「揚重物の搬出入」
図1で説明したレイアウト構成において、揚重物Wを搬入エリアAから作業エリアBに搬入する場合を説明する。このとき、各作業エリアB1、B2、B3、B4に配置されている吊り天秤組40は第1懸架部材30側の格納位置に待機させる。この状態を図2に示すが、天秤組40を構成する架橋部材40Aは第1懸架部材30に図示状態に操作紐34bで移動されロック機構33で係止ロックされている。この状態では架橋部材40Aの先端部42bは搬送軌道20から離れた位置に待機し、この架橋部材40Aに懸吊部材40Bが連結されている。従ってこの架橋部材40Aと懸吊部材40Bが不用意に移動することはなく、揚重物Wを走行トロリ21で移動しても揚重物が天秤組40に衝突することがない
"Loading and unloading lifted goods"
In the layout configuration described with reference to FIG. 1, a case where the lifted object W is carried from the carry-in area A to the work area B will be described. At this time, the suspension balance set 40 arranged in each work area B1, B2, B3, B4 is made to stand by at the storage position on the first suspension member 30 side. Although this state is shown in FIG. 2, the bridging member 40 </ b> A constituting the balance assembly 40 is moved to the first suspension member 30 by the operation string 34 b in the state shown in the figure and is locked by the lock mechanism 33. In this state, the leading end 42b of the bridging member 40A stands by at a position away from the transport track 20, and the suspension member 40B is connected to the bridging member 40A. Therefore, the bridging member 40A and the suspension member 40B do not move carelessly, and the lifted object does not collide with the balance set 40 even if the lifted object W is moved by the traveling trolley 21.

尚、この格納位置で架橋部材40Aの先端ジョイント機構42の連結扞42bはその上端連結孔42yが第1懸架部材30の先端に設けられている傾斜嵌合部32kに嵌合して位置保持されている(図3参照)。   In this retracted position, the connecting rod 42b of the tip joint mechanism 42 of the bridging member 40A is held in position by fitting its upper end connecting hole 42y to an inclined fitting portion 32k provided at the tip of the first suspension member 30. (See FIG. 3).

そこで揚重物Wを搬送レール20Lに装備されている走行トロリ21の巻上げ機23にチェンなどの牽引部材で吊り下げ支持する。そして走行トロリ21を駆動モータMO1で駆動し、所定の作業エリアBに移動する(図2の状態)。   Therefore, the lifted object W is suspended and supported by the hoisting machine 23 of the traveling trolley 21 mounted on the transport rail 20L with a pulling member such as a chain. Then, the traveling trolley 21 is driven by the drive motor MO1 and moved to a predetermined work area B (state shown in FIG. 2).

「揚重物の吊り換え」
所定の作業エリアBに揚重物Wが移送されると走行トロリ21を停止し、制動ブレーキで位置保持する。そこで揚重物Wを懸吊している牽引部材と緩衝しない位置に天秤組40を作業レール31、36に沿って移動する。例えば図示のように揚重物Wを搬送方向前後4個所で吊り下げ支持するときには、各天秤組40を揚重物Wに付設されている4個所の牽引フックWf位置に図2Y−Y方向に移動する。この天秤組40の移動はオペレータが手動で移動するか、或いはトロリ32、37に駆動モータを内蔵(不図示)して、これで移動する。
"Replacing lifted objects"
When the lift W is transferred to the predetermined work area B, the traveling trolley 21 is stopped and the position is held by the brake. Therefore, the balance set 40 is moved along the work rails 31 and 36 to a position where the lifted material W is suspended and is not buffered. For example, as shown in the figure, when the lifted object W is suspended and supported at four places before and after the conveying direction, each balance set 40 is placed at the four tow hook hooks Wf attached to the lifted object W in the Y-Y direction in FIG. Moving. The balance 40 is moved manually by the operator, or the trolleys 32 and 37 have built-in drive motors (not shown) and are moved by this.

次にオペレータは、操作ハンドル33dを把持操作してロック爪33bを解除する。すると天秤組40の架橋部材40Aは第1懸架部材30のガイドレール30Gに沿って移動可能(フリー)となる。そこで操作紐34bを操作して架橋部材40Aの先端部40bを、搬送軌道20を横切って反対側の第2懸架部材35側に移動する。   Next, the operator holds the operation handle 33d and releases the lock claw 33b. Then, the bridging member 40A of the balance assembly 40 is movable (free) along the guide rail 30G of the first suspension member 30. Accordingly, the operating string 34b is operated to move the distal end portion 40b of the bridging member 40A across the conveying track 20 to the second suspension member 35 side on the opposite side.

この架橋部材40Aの先端部40bが搬送軌道を横切った状態を図5に示すが、先端部40bはガイドレール30Gに沿って移動する際に、前述の連結扞42bの上端連結孔42yが第2懸架部材35の嵌合部38xに嵌合する。そして連結扞42bはロック爪38bで係止ロックされる。この状態で天秤組40は基端部40aを第1懸架部材30に第1第2トロリ41a、41bを介して支持され、先端部40bを第2懸架部材35に連結扞42bを介して支持されることとなる。従って天秤組40は第1第2懸架部材30、35に架橋支持され、揚重物Wの重量は、懸吊部材40B、次いで架橋部材40A、第1第2懸架部材30、35更に作業レール31、36を介して建造物10の天井に支持されることとなる。   FIG. 5 shows a state in which the distal end portion 40b of the bridging member 40A crosses the conveying track. When the distal end portion 40b moves along the guide rail 30G, the upper end coupling hole 42y of the coupling rod 42b is second. It fits into the fitting part 38x of the suspension member 35. The connecting rod 42b is locked and locked by the lock claw 38b. In this state, the balance assembly 40 is supported at the base end portion 40a by the first suspension member 30 via the first and second trolleys 41a and 41b, and at the tip end portion 40b by the second suspension member 35 via the connecting rod 42b. The Rukoto. Accordingly, the balance set 40 is bridged and supported by the first and second suspension members 30 and 35, and the weight of the lifted material W is the suspension member 40B, then the bridge member 40A, the first and second suspension members 30 and 35, and the work rail 31. , 36 is supported by the ceiling of the building 10.

そこで、作業者は懸吊部材40Bの中央部40cに位置する吊下げ連結孔40dと揚重物Wに付設されている牽引フックWfをチェンなどの牽引部材で連結する。このとき揚重物Wは搬送レール20Lの走行トロリ21に装備されている巻上げ機23で懸吊している。この懸吊部材40Bと揚重物Wの1個所又は複数個所を牽引部材で連結する作業の後、走行トロリ21の巻上げ機23を操作して揚重物Wの荷重を走行トロリ21から天秤組40に徐々にシフトする。   Therefore, the operator connects the suspension connection hole 40d located in the central portion 40c of the suspension member 40B and the tow hook Wf attached to the lifted object W by a pulling member such as a chain. At this time, the lift W is suspended by a hoisting machine 23 provided on the traveling trolley 21 of the transport rail 20L. After connecting the suspension member 40B and one or a plurality of places of the lifted article W with a pulling member, the hoisting machine 23 of the traveling trolley 21 is operated to load the load of the lifted article W from the traveling trolley 21 to the balance assembly. Gradually shift to 40.

これによって揚重物Wは走行トロリ21及び搬送レール20Lから懸吊部材40Bに吊り換えられ、その荷重は懸吊部材40Bを介して架橋部材40Aと、これを架橋支持している第1、第2懸架部材30、35に支持されることとなる。そこで走行トロリ21の牽引部材を揚重物WのフックWfから取り外す。その後、走行トロリ21は搬出入エリアAに戻り、後続する次の揚重物Wを先と異なる作業エリアBに搬送する。その手順は上述と同様である。   As a result, the lifted article W is suspended from the traveling trolley 21 and the transport rail 20L to the suspension member 40B, and the load is bridged through the suspension member 40B to the bridging member 40A and the first and second bridges supporting it. The two suspension members 30 and 35 are supported. Therefore, the traction member of the traveling trolley 21 is removed from the hook Wf of the lifted object W. Thereafter, the traveling trolley 21 returns to the carry-in / out area A, and transports the subsequent lifted object W to the work area B different from the previous one. The procedure is the same as described above.

「揚重物の分解・組立」
図5に天秤組40に揚重物Wを吊り下げ支持した状態を示すが、この状態で揚重物Wは1個所若しくは複数個所(図示のものは4個所)を懸吊部材40Bに吊り下げ支持されている。そこで、例えば揚重物Wを分解修理する場合は、作業エリアBで分解作業を実施し、揚重物Wをユニットに分解する。また、作業エリアBで組立作業を実施する場合には前述した手順で搬出入エリアAから所定の作業エリアBに揚重物(ユニット)を搬送し、懸吊部材40Bに掛け替え懸吊する。このように順次搬入された揚重物(ユニット)を組立てる。
"Disassembly and assembly of lifted goods"
FIG. 5 shows a state in which the lifted object W is suspended and supported by the balance assembly 40. In this state, the lifted object W is suspended at one or a plurality of places (four places in the drawing) from the suspension member 40B. It is supported. Therefore, for example, when disassembling and repairing the lifted object W, the disassembling work is performed in the work area B, and the lifted object W is disassembled into units. Further, when the assembly work is performed in the work area B, the lifted object (unit) is transported from the carry-in / out area A to the predetermined work area B according to the procedure described above, and is suspended by being suspended on the suspension member 40B. In this way, the lifted objects (units) sequentially carried in are assembled.

上述のように各作業エリアBで分解或いは組立など所定の作業を実施する際に揚重物(ユニット)Wは作業レール31、36に沿って移動し、複数の揚重物(ユニット)W相互の間隔を作業に適するように移動する。このときは各ユニットを吊下げ支持している天秤組40を作業レール31、36に沿って例えば作業者が手動で移動する。   As described above, when a predetermined work such as disassembly or assembly is performed in each work area B, the lifted object (unit) W moves along the work rails 31 and 36, and a plurality of lifted objects (units) W are mutually connected. Move the interval to suit the work. At this time, for example, an operator manually moves the balance set 40 that supports each unit in a suspended manner along the work rails 31 and 36.

「揚重物の転送」
そこで、分解或いは組立てた揚重物(ユニット)を別の作業エリアBに転送する場合、或いは修理・組立作業後の揚重物Wを搬出入エリアAに搬送する場合には、図7に示すように懸吊部材40Bを架橋部材40Aから分離する。この分離作業は、揚重物(ユニット或いは完成物)の吊上げ連結孔40e(複数の場合は選択された1つ又は2つの連結孔)位置に、搬送レール20Lに装備されている走行トロリ21を移動する。そしてこのトロリ21の巻上げ機23と吊上げ連結孔40eとを牽引部材で連結する。この連結後に巻上げ機23で懸吊部材40Bを吊上げる。すると懸吊部材40Bは架橋部材40Aから上方に分離して揚重物Wの重量は巻上げ機23で吊り下げ支持される。
"Transfer of lifted goods"
Therefore, when transferring the disassembled or assembled lifted object (unit) to another work area B, or when transporting the lifted object W after repair / assembly work to the carry-in / out area A, it is shown in FIG. Thus, the suspension member 40B is separated from the bridging member 40A. This separation operation is performed by placing the traveling trolley 21 mounted on the transport rail 20L at the position of the lifting connection hole 40e (one or two selected connection holes in a plurality of cases) of the lifted object (unit or finished product). Moving. And the hoisting machine 23 of this trolley 21 and the lifting connection hole 40e are connected by a traction member. After this connection, the hoisting member 40B is lifted by the hoisting machine 23. Then, the suspension member 40B is separated upward from the bridging member 40A, and the weight of the lifted material W is suspended and supported by the hoisting machine 23.

次に架橋部材40Aの先端部40bを搬送軌道20から第1懸架部材30側に退避させる。このため作業者はレバー39rを操作してロック爪38bを操作し、架橋部材40Aの先端ジョイント機構42(連結扞42bの係止)をロック解除する。このロック解除の後、使用者は操作紐34bを操作して架橋部材40Aを図3の格納位置に移動する。このように懸吊部材40Bを架橋部材40Aから分離して揚重物Wを所定位置に移動した後、この懸吊部材40Bは元の作業エリアに戻り、図3の状態に格納位置に格納される。   Next, the front end portion 40b of the bridging member 40A is retracted from the transport track 20 to the first suspension member 30 side. For this reason, the operator operates the lever 39r to operate the lock claw 38b, and unlocks the tip joint mechanism 42 (engagement of the connecting rod 42b) of the bridging member 40A. After unlocking, the user operates the operation string 34b to move the bridging member 40A to the storage position in FIG. After separating the suspension member 40B from the bridging member 40A and moving the lift W to a predetermined position, the suspension member 40B returns to the original work area and is stored in the storage position in the state of FIG. The

尚、本発明にあって、懸吊部材40Aの先端部40bを搬送軌道20から退避させて格納し、揚重物Wの搬入後に搬送軌道を横切って反対側に位置する第2懸架部材35に連結する際に、この懸吊部材40Bの基端部40aを第1懸架部材30に摺動自在に連結する場合について説明したが、この懸吊部材40Aの基端部40aを第1懸架部材30に回動自在に軸支持しても良い。この場合には、例えば第1懸架部材30に軸受け部を設け、この軸受け部に懸吊部材40Aの基端部40aを回動ピンで軸支持する。これによって懸吊部材40Aは回動ピンを中心に所定角度(例えば90度〜180度)回転させることによって天秤先端部40bは搬送軌道20から退避した位置(格納位置)と軌道20を横切って反対側に位置する第2懸架部材35に架橋(連結位置)させることが出来る。   In the present invention, the distal end portion 40b of the suspension member 40A is retracted from the conveyance track 20 and stored, and the second suspension member 35 located on the opposite side across the conveyance track after the lifted material W is loaded is stored in the second suspension member 35. Although the case where the base end portion 40a of the suspension member 40B is slidably connected to the first suspension member 30 when connecting is described, the base end portion 40a of the suspension member 40A is connected to the first suspension member 30. The shaft may be rotatably supported. In this case, for example, the first suspension member 30 is provided with a bearing portion, and the base end portion 40a of the suspension member 40A is axially supported on the bearing portion by a rotation pin. As a result, the suspension member 40A is rotated by a predetermined angle (for example, 90 degrees to 180 degrees) around the rotation pin, so that the balance tip end portion 40b is opposite to the position retracted from the transport track 20 (storage position) across the track 20. The second suspension member 35 located on the side can be bridged (connected position).
