この発明は、昇降路内の頂部寄りに配置された巻上機の支持部材を、昇降路に立設されてつり合おもりの昇降を案内するつり合おもり用レールの上端部によって支持するエレベーター装置に関する。   The present invention provides an elevator apparatus that supports a hoisting machine support member disposed near the top in a hoistway by an upper end portion of a counterweight rail that is erected on the hoistway and guides the lifting and lowering of the counterweight. About.

図４及び図５は、例えば日本特開２０００−３１８９４６号公報に示された構成に類似した従来のエレベーター装置を示す図で、図４は縦断面図、図５は図４の要部横断面図である。図において、１はエレベーターの昇降路、２は昇降路１を昇降するかご、３は昇降路１に立設されて水平投影面においてかご２の両側にそれぞれ配置されてかご２の昇降を案内するかご用レールである。
４はレールブラケットで、一側が昇降路１の側面を形成した梁からなる固定体５に固定されて他側にはかご用レール３が締結され、昇降路１に上下方向に互いに離れて配置されている。
６はつり合おもり用レールで、昇降路１に立設されて水平方向に互いに離れて二列が配置されて二列の内の一列がレールブラケット４に締結され、他の一列は固定体５に固定されて昇降路１に上下方向に互いに離れて配置されたつり合おもり用ブラケット７に締結され、二列の間に配置されて昇降路１を昇降するつり合おもり８の昇降を案内する。
９は昇降路１の頂部寄りに配置された巻上機、１０は両端がそれぞれつり合おもり用レール６の上端部に連結されて巻上機９を支持する支持部材、１１はかご用レール３の上端寄りに突設された綱止め腕である。
１２は主索で、一端が綱止め腕１１に連結されかご２の下部に枢着されたかご滑車１３に巻掛けられて上方に延長され、巻上機９の駆動綱車に巻掛けられて下方に延長されつり合おもり８の吊り車１４に巻掛けられて、他端は支持部材１０に連結されている。
従来のエレベーター装置は上記のように構成され、巻上機９が運転されると主索１２を介してかご２及びつり合おもり８が互いに反対方向へ昇降する。そして、巻上機９の自重、主索１２の張力による荷重が、綱止め腕１１を介してかご用レール３、また支持部材１０を介してつり合おもり用レール６によって支持される。
このような構成において主索１２の張力等による下向きの荷重の大半がつり合おもり用レール６に軸方向の圧縮力として作用するので、つり合おもり用レール６はつり合おもり８の案内機能のために要する軸直角方向の曲げ強度に加え軸方向の圧縮力による強度も必要なため、軸方向の圧縮力が作用しない場合に比べ大サイズのつり合おもり用レール６が立設される。このため、エレベーター装置の製作費が嵩むという問題点があった。
なお、図４及び図５に示すエレベーター装置の構成では、昇降路１すなわちエレベーター装置が設置される建屋側にエレベーター装置のために作用する鉛直方向荷重が少なくなり建築費を低減することができる。また、建屋が鋼材を組立てた骨組に、アンカーボルトが立設不能な壁材が被着された構造、すなわち柔構造である場合には、建屋の階床を構成する骨組材にレールブラケット４、つり合おもり用ブラケット７を固定することになる。
このため、レールブラケット４等の上下方向の配置間隔は建屋の階高と同じになり、通常３ｍ〜４ｍの間隔でかご用レール３等を支持することになる。そして、つり合おもり用レール６に鉛直荷重が作用する場合に、支持間隔が長くなると座屈が発生するので、支持間隔に対応してつり合おもり用レール６を大サイズ化する必要がある。
したがって、この発明はつり合おもりの昇降を案内するつり合おもり用レールに圧縮荷重が作用する構成に対して、標準サイズのつり合おもり用レールを使用し支持間隔が長くなっても座屈が発生しないエレベーター装置を得ることを目的とする。 4 and 5 are views showing a conventional elevator apparatus similar to the structure shown in, for example, Japanese Patent Application Laid-Open No. 2000-318946. FIG. 4 is a longitudinal sectional view, and FIG. FIG. In the figure, 1 is an elevator hoistway, 2 is a car that raises and lowers the hoistway 1, and 3 is standing on the hoistway 1 and is arranged on both sides of the car 2 on the horizontal projection plane to guide the raising and lowering of the car 2. This is a rail for a car.
Reference numeral 4 denotes a rail bracket, one side of which is fixed to a fixed body 5 made of a beam that forms the side surface of the hoistway 1, and the other side is fastened with a car rail 3, which is arranged on the hoistway 1 apart from each other in the vertical direction. ing.
Reference numeral 6 denotes a counterweight rail, which is erected on the hoistway 1 and arranged in two rows apart from each other in the horizontal direction. One of the two rows is fastened to the rail bracket 4, and the other row is fixed to the fixed body 5. It is fastened to a counterweight bracket 7 that is fixed and arranged apart from each other in the vertical direction on the hoistway 1 and guides the raising and lowering of the counterweight 8 that is arranged between two rows and moves up and down the hoistway 1.
9 is a hoisting machine disposed near the top of the hoistway 1, 10 is a support member that supports the hoisting machine 9 by connecting both ends to the upper end of the counterweight rail 6, and 11 is a car rail 3. It is a rope stop arm projecting near the upper end of.
Reference numeral 12 denotes a main rope, one end of which is connected to the rope stopping arm 11 and is pivotally attached to the lower part of the car 2, is wound around the car pulley 13, is extended upward, and is wound around the driving sheave of the hoisting machine 9. The other end of the counterweight 8 is wound around the suspension wheel 14 of the counterweight 8, and the other end is connected to the support member 10.
The conventional elevator apparatus is configured as described above, and when the hoisting machine 9 is operated, the car 2 and the counterweight 8 are lifted and lowered in opposite directions via the main rope 12. Then, the load due to the own weight of the hoisting machine 9 and the tension of the main rope 12 is supported by the rail 3 for the cage 3 and the rail 6 for the counterweight via the support member 10 via the rope retaining arm 11.
In such a configuration, most of the downward load due to the tension of the main rope 12 acts on the counterweight rail 6 as an axial compressive force. Therefore, the counterweight rail 6 serves as a guide function for the counterweight 8. In addition to the bending strength in the direction perpendicular to the axis required for the shaft, the strength by the axial compressive force is also required, and therefore, the large-sized counterweight rail 6 is erected as compared with the case where the axial compressive force does not act. For this reason, there existed a problem that the manufacturing cost of an elevator apparatus increased.
In addition, in the structure of the elevator apparatus shown in FIG.4 and FIG.5, the vertical load which acts for the elevator apparatus on the hoistway 1, ie, the building side in which an elevator apparatus is installed, decreases, and a construction cost can be reduced. Further, when the building is a structure in which the steel material is assembled and the wall material on which the anchor bolt cannot be erected is attached, that is, a flexible structure, the rail bracket 4 is attached to the frame material constituting the floor of the building, The counterweight bracket 7 is fixed.
For this reason, the arrangement | positioning space | interval of the up-down direction of the rail bracket 4 grade | etc., Becomes the same as the floor height of a building, and will normally support the rail 3 for cars by the space | interval of 3m-4m. Then, when a vertical load is applied to the counterweight rail 6, buckling occurs when the support interval becomes long. Therefore, it is necessary to increase the size of the counterweight rail 6 according to the support interval.
Therefore, according to the present invention, a compressive load is applied to the counterweight rail that guides the lifting and lowering of the counterweight, but buckling occurs even when the support interval is increased by using a standard-size counterweight rail. The purpose is to obtain an elevator device that does not.

この発明は、昇降路内の頂部寄りに配置され、支持部材により支持された巻上機と、この巻上機により主索を介して運転されて上記昇降路を互いに反対方向に昇降するかご及びつり合おもりと、上記昇降路に立設されて上記かごの両側にそれぞれ配置されてかごの昇降を案内するかご用レールと、一側が上記昇降路の固定体に固定されて他側には上記かご用レールの一列が締結され、上記昇降路に上下方向に互いに離れて配置されたレールブラケットと、上記昇降路に立設されて水平方向に互いに離れて二列が配置され上端部により上記巻上機の支持部材を支持し、上記二列の内の一列が上記レールブラケットに締結され、他の一列は上記固定体に固定されて上記昇降路に上下方向に互いに離れて配置されたつり合おもり用ブラケットに締結され、上記二列の間に配置された上記つり合おもりの昇降を案内するつり合おもり用レールと、上下方向における上記レールブラケットの相互間に配置され、一側に上記かご用レールが締結され他側には対向した上記つり合おもり用レールの内の一列が締結された連結体とを備え、上記主索は、一端の綱止め具が上記かご用レールの上端寄りに連結され、かご滑車に巻掛けられて上方に延長され、上記巻上機の駆動綱車に巻掛けられて下方に延長されつり合おもりの吊り車に巻掛けられて、他端の綱止め具が上記巻上機の支持部材におけるレールブラケット側のつり合おもりレール寄り位置に連結されていることを特徴とするエレベーター装置である。
これによって、エレベーターの主索の張力等による下向きの荷重によって、連結体寄りのつり合おもり用レールに発生する軸直角方向の変位が連結体を介してかご用レールに伝達されて支持される。したがって、連結体寄りのつり合おもり用レールはサイズを過大にすることなく座屈しないつり合おもりレールが得られるため、エレベーター装置の製作費低減が可能になる。 This invention is arranged near the top in the hoistway and is supported by a support member, and a car that is driven by the hoisting machine via a main rope to move up and down the hoistway in opposite directions. A counterweight, a rail for a car standing on the hoistway and arranged on both sides of the car to guide the raising and lowering of the car, one side being fixed to the fixed body of the hoistway and the other side being the above One row of car rails is fastened, and rail brackets arranged vertically apart from each other in the hoistway, and two rows arranged vertically apart from each other in the hoistway and arranged above the hoistway by the upper end. Supporting the support member of the upper machine, one of the two rows is fastened to the rail bracket, and the other row is fixed to the fixed body, and is balanced in the hoistway and spaced apart from each other in the vertical direction. Fastened to the weight bracket It is arranged between the counterweight rail that guides the lifting and lowering of the counterweight arranged between the two rows, and the rail bracket in the vertical direction, and the car rail is fastened to one side. The other side is provided with a connecting body to which one row of the counterweight rails facing each other is fastened, and the main rope has a rope stopper at one end connected to the upper end of the car rail, and a car pulley. Is wound around the drive sheave of the hoisting machine, is extended downward and is wound around the suspension weight of the counterweight, and the rope stopper at the other end is attached to the hoisting machine. It is the elevator apparatus characterized by being connected to the position near the counterweight rail on the rail bracket side in the support member.
As a result, due to a downward load caused by the tension of the main rope of the elevator or the like, the displacement in the direction perpendicular to the axis generated in the counterweight rail close to the connecting body is transmitted to and supported by the car rail through the connecting body. Therefore, the counterweight rail close to the connecting body can be obtained as a counterweight rail that does not buckle without being oversized, so that the manufacturing cost of the elevator apparatus can be reduced.

この発明をより詳細に説述するために、添付の図面に従ってこれを説明する。すなわち、図１〜図３において、１はエレベーターの昇降路、２は昇降路１を昇降するかご、３は昇降路１に立設されて水平投影面においてかご２の両側にそれぞれ配置されてかご２の昇降を案内するかご用レールである。
４はレールブラケットで、一側が昇降路１の側面を形成した梁からなる固定体５に固定されて他側にはかご用レール３が締結され、昇降路１に上下方向に互いに離れて配置されている。
６はつり合おもり用レールで、昇降路１に立設されて水平方向に互いに離れて二列が配置されて二列の内の一列がレールブラケット４に締結され、他の一列は固定体５に固定されて昇降路１に上下方向に互いに離れて配置されたつり合おもり用ブラケット７に締結され、二列の間に配置されて昇降路１を昇降するつり合おもり８の昇降を案内する。
９は昇降路１内の頂部寄りに配置された巻上機、１０は両端がそれぞれつり合おもり用レール６の上端部に連結されて巻上機９を支持する支持部材、１１はかご用レール３の上端寄りに突設された綱止め腕である。
１２は主索で、一端の綱止め具１５が綱止め腕１１に連結されかご２の下部に枢着されたかご滑車１３に巻掛けられて上方に延長され、巻上機９の駆動綱車に巻掛けられて下方に延長されつり合おもり８の吊り車１４に巻掛けられて、他端の綱止め具１６は支持部材１０におけるレールブラケット４側のつり合おもり用レール６寄り位置に連結されている。
１７は連結体で、上下方向におけるレールブラケット４の相互間に少なくとも一つが配置されて一側にかご用レール３が、レールクリップ１８及び連結体１７の縁部に挿通されたボルト１９並びにボルト１９の挿通端にねじ込まれたナット２０によって締結される。また、他側には対向したつり合おもり用レール６が、レールクリップ２１及び連結体１７の縁部に挿通されたボルト２２並びにボルト２２の挿通端にねじ込まれたナット２３によって締結される。
上記のように構成されたエレベーター装置において、巻上機９が運転されると主索１２を介してかご２及びつり合おもり８が互いに反対方向へ昇降する。そして、巻上機９の自重、主索１２の張力による荷重が、綱止め腕１１を介してかご用レール３、また支持部材１０を介してつり合おもり用レール６によって支持される。
このような構成において主索１２の張力等による下向きの荷重の大半がつり合おもり用レール６に作用するので、この荷重による座屈がつり合おもり用レール６に発生する。しかし、上下方向におけるレールブラケット４の相互間に少なくとも一個所に連結体１７が配置されて、かご用レール３につり合おもり用レール６が連結されている。
このため、主索１２の張力等による下向きの荷重によって、つり合おもり用レール６に発生する軸直角方向の変位が連結体１７を介してかご用レール３に伝達されて支持される。したがって、つり合おもり用レール６は座屈しなくなるので、つり合おもり８の案内機能のために要する強度に近づけることができる。
このため、簡易な装置構成により、また煩雑な手数を要することなくつり合おもり用レール６を標準的サイズ化、すなわちサイズを小さくすることが可能になりエレベーター装置の製作費を低減することができる。
また、連結体１７に対してかご用レール３及びつり合おもり用レール６が、それぞれレールクリップ１８、レールクリップ２１を介して締結される。このため、上下方向における適所において容易に連結体１７によりかご用レール３及びつり合おもり用レール６を連結することができ、またつり合おもり用レール６の軸直角方向の変位量を所定値に制限するために連結体１７の数を適宜に増加することも容易に可能となる。
したがって、エレベーター装置ごとに相違するつり合おもり用レール６の軸直角方向の変位量に容易に対応でき、簡易な作業によってつり合おもり用レール６の軸直角方向の変位対策を容易に実施することができる。
また、主索１２のつり合おもり８側の綱止め具１６が、支持部材１０における連結体１７に締結されたつり合おもり用レール６側の端部寄りに配置される。これにより綱止め具１６に作用する鉛直荷重の多くが、連結体１７に締結されたつり合おもり用レール６によって支持されて、綱止め具１６の荷重による連結体１７寄りのつり合おもり用レール６の軸直角方向の変位が、連結体１７を介してかご用レール３に伝達されて支持される。
したがって、連結体１７寄りのつり合おもり用レール６は座屈しなくなるので、連結体１７寄りのつり合おもり用レール６の強度をつり合おもり８の案内機能のために要する強度に近づけることができ、つり合おもり用レール６を標準的サイズ化することができてエレベーター装置の製作費を低減することができる。 In order to describe the present invention in more detail, it will be described with reference to the accompanying drawings. That is, in FIGS. 1 to 3, reference numeral 1 denotes an elevator hoistway, 2 denotes a car that raises and lowers the hoistway 1, and 3 denotes a car that stands on the hoistway 1 and is arranged on both sides of the car 2 on a horizontal projection plane. It is a rail for a car which guides the raising and lowering of 2.
Reference numeral 4 denotes a rail bracket, one side of which is fixed to a fixed body 5 made of a beam that forms the side surface of the hoistway 1, and the other side is fastened with a car rail 3, which is arranged on the hoistway 1 away from each other vertically. ing.
Reference numeral 6 denotes a counterweight rail, which is erected on the hoistway 1 and arranged in two rows apart from each other in the horizontal direction. One of the two rows is fastened to the rail bracket 4, and the other row is fixed to the fixed body 5. It is fastened to a counterweight bracket 7 that is fixed and arranged apart from each other in the vertical direction on the hoistway 1 and guides the raising and lowering of the counterweight 8 that is arranged between two rows and moves up and down the hoistway 1.
9 is a hoisting machine disposed near the top of the hoistway 1, 10 is a support member that supports the hoisting machine 9 by connecting both ends to the upper end of the counterweight rail 6, and 11 is a car rail 3 is a leash arm projecting toward the upper end of 3.
Reference numeral 12 denotes a main rope, and a leash stopper 15 at one end is connected to the leash arm 11 and is pivotally attached to the lower portion of the car 2 and is wound around a car pulley 13 and extended upward. The other end of the rope stopper 16 is connected to a position closer to the counterweight rail 6 on the rail bracket 4 side of the support member 10 by being wound around the suspension wheel 14 of the counterweight 8. Has been.
Reference numeral 17 denotes a connecting body, and at least one rail rail 4 is disposed between the rail brackets 4 in the vertical direction, and the car rail 3 is inserted on one side of the rail clip 18 and the edge of the connecting body 17 and the bolt 19. It is fastened by a nut 20 screwed into the insertion end. On the other side, the opposite counterweight rail 6 is fastened by a bolt 22 inserted into the rail clip 21 and the edge of the connecting body 17 and a nut 23 screwed into the insertion end of the bolt 22.
In the elevator apparatus configured as described above, when the hoisting machine 9 is operated, the car 2 and the counterweight 8 are lifted and lowered in opposite directions via the main rope 12. Then, the load due to the own weight of the hoisting machine 9 and the tension of the main rope 12 is supported by the rail 3 for the cage 3 and the rail 6 for the counterweight via the support member 10 via the rope retaining arm 11.
In such a configuration, most of the downward load due to the tension of the main rope 12 acts on the counterweight rail 6, so that buckling due to this load occurs in the counterweight rail 6 . However, the connecting body 17 is disposed at least at one location between the rail brackets 4 in the vertical direction, and the counterweight rail 6 is connected to the car rail 3.
Therefore, the displacement in the direction perpendicular to the axis generated in the counterweight rail 6 by the downward load due to the tension of the main rope 12 is transmitted to the car rail 3 via the connecting body 17 and supported. Accordingly, since the counterweight rail 6 does not buckle, the strength required for the function of the counterweight 8 can be approached.
For this reason, the balance weight rail 6 can be standardized, that is, the size can be reduced with a simple device configuration and without requiring complicated work, and the manufacturing cost of the elevator apparatus can be reduced. .
In addition, the car rail 3 and the counterweight rail 6 are fastened to the connecting body 17 via a rail clip 18 and a rail clip 21, respectively. For this reason, the car rail 3 and the counterweight rail 6 can be easily connected by the connecting body 17 at an appropriate position in the vertical direction, and the amount of displacement of the counterweight rail 6 in the direction perpendicular to the axis is set to a predetermined value. In order to limit, it is possible to easily increase the number of the coupling bodies 17 appropriately.
Therefore, it is possible to easily cope with the amount of displacement of the counterweight rail 6 in the direction perpendicular to the axis, which is different for each elevator device, and to easily take measures against the displacement of the counterweight in the direction perpendicular to the axis by simple work. Can do.
Further, the rope stopper 16 on the counterweight 8 side of the main rope 12 is arranged near the end on the counterweight rail 6 side fastened to the connecting body 17 in the support member 10. Accordingly, most of the vertical load acting on the rope stopper 16 is supported by the counterweight rail 6 fastened to the coupling body 17, and the counterweight rail near the coupling body 17 due to the load of the rope stopper 16. 6 is transmitted to and supported by the car rail 3 through the connecting body 17.
Therefore, the counterweight rail 6 near the connecting body 17 does not buckle, so that the strength of the counterweight rail 6 near the connecting body 17 can be made close to the strength required for the guide function of the counterweight 8. The counterweight rail 6 can be standard sized, and the manufacturing cost of the elevator apparatus can be reduced.

以上説明したように、この発明にかかるエレベーター装置においては、エレベーター装置が設置される建屋が鋼材を組立てた骨組に、アンカーボルトが立設不能な壁材が被着されてなる柔構造である場合に、建屋の階床を構成する骨組材にレールブラケットが固定される。そして、昇降路内の頂部寄りに配置された巻上機の支持部材を、昇降路に立設されてつり合おもりの昇降を案内するつり合おもり用レールの上端部によって支持する構成に対して、次に述べるようにしてつり合おもり用レールの軸方向の圧縮荷重による座屈をなくすことができる。
すなわち、かご用レールを昇降路の固定体に固定するレールブラケットの上下方向の相互間に配置された連結体によって、連結体寄りのつり合おもり用レールがかご用レールに連結される。これによって、連結体寄りのつり合おもり用レールに発生する軸直角方向の変位が連結体を介してかご用レールに伝達されて支持される。したがって、連結体寄りのつり合おもり用レールは座屈しなくなるので、つり合おもりの案内機能のために要する強度に近づけることができる。このため、連結体寄りのつり合おもり用レールを標準的サイズの小さいサイズのものとすることが可能になりエレベーター装置の製作費を低減する効果を得ることができる。 As described above, in the elevator apparatus according to the present invention, the building in which the elevator apparatus is installed has a flexible structure in which a wall material in which an anchor bolt cannot be erected is attached to a framework in which steel materials are assembled. In addition, the rail bracket is fixed to the frame material constituting the floor of the building. And with respect to the structure which supports the supporting member of the hoisting machine arrange | positioned near the top part in a hoistway by the upper end part of the balance weight rail which stands in the hoistway and guides the raising / lowering of a counterweight The buckling due to the axial compressive load of the counterweight rail can be eliminated as described below.
That is, the counterweight- side counterweight rails are connected to the car rails by the connecting bodies arranged between the rail brackets in the vertical direction that fix the car rails to the hoistway fixing bodies. As a result, the displacement in the direction perpendicular to the axis generated in the counterweight rail near the connecting body is transmitted to and supported by the car rail through the connecting body. Accordingly, since the counterweight rail near the connecting body does not buckle, it can be brought close to the strength required for the counterweight guide function.
