特許文献１に示されたかご吊車取付装置においては、かご枠下梁の下方にかご枠下梁の長手方向とは斜交するように渡した吊車取付梁の両端部に吊車を配置しているため、この吊車取付梁の厚さの分だけエレベータ乗りかごの寸法が下方に大きくなり、昇降路下部に設けられるピットの深さをその分だけ深くしなければならないという課題があった。更に、斜め材である吊車取付梁を備えることにより、乗りかご全体の重量が大きくなり、また構造も複雑化するという課題もある。
また、特許文献２に示されたかご吊車取付装置においては、かご枠下梁と平行に別途吊車取付梁を設けているため、吊車を取付けるための部材はこの場合においても必要であり、乗りかご全体の重量が吊車取付部材を備えない場合に比して大きくなるという課題が存在すると共に、かご枠下梁及び上梁にガイドシューを介して係合したガイドレールが乗りかごを支持する支持点と、吊車に巻き掛けられた主索が乗りかごを吊る吊点とを一致させることができないため、次に挙げる２つの課題が生じる。
即ち、１つは、ガイドレールによる支持点と主索による吊点とのずれから偏荷重が生じ、ガイドシュー及びガイドレールの磨耗が激しくなる点であり、もう１つはガイドレールに対向してかご枠下梁に設けた非常止め装置が作動した際に吊車及び吊車取付梁に掛かる慣性モーメントに備え、十分強固に吊車及び吊車取付梁を固設しなければならないため、これらの固設構造が複雑化する点である。
特許文献３に示されたかご吊車取付装置においては、かご枠下梁両端部の一方側面と他方側面に、ガイドシューと非常止装置とを設け、一対のガイドレールを前記ガイドレールと非常止装置とに対応するように奥行き方向の前後にずらせて配設している。このため、乗りかご全体が鉛直軸に対し回転してガイドレールとガイドシューの交合が外れる恐れがあり、この交合外れを防ぐための外れ止めが別途必要になる等の課題があった。 In the car suspension vehicle mounting apparatus disclosed in Patent Document 1, suspension vehicles are arranged at both ends of a suspension vehicle attachment beam that passes under the car frame lower beam so as to be oblique to the longitudinal direction of the car frame lower beam. Therefore, there has been a problem that the size of the elevator car increases downward by the thickness of the suspension car mounting beam, and the depth of the pit provided at the lower part of the hoistway has to be increased accordingly. Furthermore, the provision of the suspension vehicle mounting beam, which is an oblique member, raises the problem that the weight of the entire car is increased and the structure is complicated.
In addition, in the car suspension vehicle mounting apparatus disclosed in Patent Document 2, a separate suspension vehicle mounting beam is provided in parallel with the car frame lower beam. Therefore, a member for mounting the suspension vehicle is also necessary in this case. There is a problem that the overall weight is increased compared to the case where the suspension vehicle mounting member is not provided, and a support point where the guide rail engaged with the lower beam and the upper beam of the car frame via the guide shoe supports the car. And the main rope wound around the suspension vehicle cannot match the suspension point at which the car is suspended, so the following two problems arise.
That is, one is a point in which an offset load is generated due to a deviation between the support point by the guide rail and the suspension point by the main rope, and the wear of the guide shoe and the guide rail becomes intense, and the other is the opposite of the guide rail. In order to prepare for the moment of inertia applied to the suspension car and the suspension car mounting beam when the emergency stop device provided on the car frame lower beam is activated, the suspension car and the suspension car mounting beam must be secured sufficiently. It is a complicated point.
In the car suspension vehicle mounting apparatus disclosed in Patent Document 3, a guide shoe and an emergency stop device are provided on one side surface and the other side surface of both ends of the car frame lower beam, and the pair of guide rails are connected to the guide rail and the emergency stop device. Are arranged so as to be shifted back and forth in the depth direction so as to correspond to the above. For this reason, there is a possibility that the entire car will rotate with respect to the vertical axis and the coupling between the guide rail and the guide shoe may be disengaged, and there is a problem that a separate stopper is required to prevent this disengagement.

一方、特許文献４に示された従来のエレベータの綱止装置においても、かご枠下梁の下方にかご枠下梁の長手方向とは斜交するように渡した綱止取付梁の両端部に綱止を配置しているため、この綱止取付梁の厚さの分だけエレベータ乗りかごの寸法が下方に大きくなり、昇降路下部に設けられるピットの深さをその分だけ深くしなければならないという課題、及び、乗りかご全体の重量が大きくなり、かつ、構造が複雑化するという課題がある。   On the other hand, in the conventional elevator pawl device shown in Patent Document 4, both ends of the pawl mounting beam passed below the car frame lower beam so as to be oblique to the longitudinal direction of the car frame lower beam. Since the pawl is located, the elevator car size will increase downward by the thickness of the pawl mounting beam, and the depth of the pit provided at the lower part of the hoistway must be increased accordingly. And the problem that the weight of the entire car is increased and the structure is complicated.

この発明は、前述のような課題を解決するためになされたもので、第１の目的はピット深さを浅くできるかご吊車取付装置及び綱止装置を得るものである。
また、第２の目的は第１の目的に加え、乗りかごの重量を軽量化できるかご吊車取付装置及び綱止装置を従来より安価に得るものである。 The present invention has been made to solve the above-described problems, and a first object is to provide a car suspension vehicle mounting device and a pawl device that can reduce the pit depth.
In addition to the first object, the second object is to obtain a car suspension vehicle attachment device and a rope anchoring device that can reduce the weight of the car at a lower cost than conventional ones.

Here, an embodiment relating to a 2: 1 roping lift elevator will be described. Guide rails 1 are vertically attached to both side walls of a hoistway (not shown), and a car frame is disposed between the guide rails 1 via a guide shoe 2 so as to be lifted and lowered. The car is installed with a car supported from below.

前記かご枠は２本のかご枠縦柱３、かご枠上梁４及びかご枠下梁５を主要素として構成されている。前記かご枠縦柱３は、コの字状の断面を持ち、その上下両端凹陥部内に前記ガイドレール１に対向して内設された前記ガイドシュー２を介して、その凹陥部がそれぞれ左右の前記ガイドレール１に対向して上下動自在に配置される。
前記かご枠上梁４はコの字状の断面を持つ一対の枠材であって、互いにその凹陥部を外向して、前記かご枠縦柱３の上部を前後より挟む様にして左右前記かご枠縦柱３間に渡設される。同様に 前記かご枠下梁５もコの字状の断面を持つ一対の枠材であって、互いにその凹陥部を外向して、前記かご枠縦柱３の下部を前後より挟む様にして左右前記かご枠縦柱３間に渡設されるが、この時、前記かご枠下梁５を構成する枠材対は、前記かご枠縦柱３に内設された前記ガイドシュー２の高さ寸法だけ、前記かご枠縦柱３下端より上方の位置で、これを挟持する。このような構造にすることにより、前記かご枠上梁４を構成する枠材対及び前記かご枠下梁５を構成する枠材対同士は、前記かご枠縦柱３の幅だけ間隙を擁して配置されることになる。なお、この際、前記かご枠上梁４を構成する枠材対同士は、繋ぎ材４ａにより繋止される。
前記かご枠縦柱３には、押圧体７ａと非常止作動コロ７ｂとからなる早ぎき非常止装置７が、前記かご枠縦柱３凹陥部内の前記かご枠下梁５との交部に位置するように内設されており、左右の前記非常止装置７同士は、内蔵された前記非常止作動コロ７ｂが応動するように、非常止作動レバー８及び連結軸９ａにより連結されている。なお、前記非常止作動レバー８の一方には引上棒８ａが回動自在に軸着され、また、前記連結軸９ａは、前記かご枠下梁５の左右に設けられた軸受枠８ｂにより回動自在に軸支されている。前記昇降路の最下部にあるピット床（図示せず）の中央には衝撃を緩和する緩衝器１０が設置され、前記かご枠下梁５中央下部の前記緩衝器１０に対応する位置には緩衝器当て板１１が備えられている。 The car frame is composed of two car frame vertical columns 3, a car frame upper beam 4, and a car frame lower beam 5 as main elements. The car frame vertical column 3 has a U-shaped cross section, and the recesses are formed on the left and right sides of the recesses through the guide shoes 2 provided opposite to the guide rails 1. Opposed to the guide rail 1 is arranged to be movable up and down.
The car frame upper beam 4 is a pair of frame members having a U-shaped cross section, and the left and right cars are arranged so that the concave portions of the car frame are directed outward and the upper part of the car frame vertical column 3 is sandwiched from the front and rear. It is passed between the frame vertical pillars 3. Similarly, the car frame lower beam 5 is also a pair of frame members having a U-shaped cross section, and the left and right sides of the car frame vertical column 3 are sandwiched between the front and rear sides with the concave portions facing outward. At this time, the pair of frame members constituting the car frame lower beam 5 is a height dimension of the guide shoe 2 provided in the car frame vertical column 3. Only this is clamped at a position above the lower end of the car frame vertical column 3. By adopting such a structure, the frame material pair constituting the car frame upper beam 4 and the frame material pair constituting the car frame lower beam 5 have a gap corresponding to the width of the car frame vertical column 3. Will be placed. At this time, the frame material pairs constituting the car frame upper beam 4 are locked by the connecting material 4a.
In the car frame vertical column 3, an early emergency stop device 7 including a pressing body 7 a and an emergency stop roller 7 b is positioned at an intersection with the car frame lower beam 5 in the recessed portion of the car frame vertical column 3. The left and right emergency stop devices 7 are connected to each other by an emergency stop operating lever 8 and a connecting shaft 9a so that the built-in emergency stop roller 7b responds. A lifting rod 8a is pivotally attached to one of the emergency stop operating levers 8, and the connecting shaft 9a is rotated by bearing frames 8b provided on the left and right sides of the car frame lower beam 5. It is pivotally supported. A shock absorber 10 is provided at the center of a pit floor (not shown) at the lowermost part of the hoistway, and a shock absorber 10 is disposed at a position corresponding to the shock absorber 10 at the lower center of the car frame lower beam 5. An instrument plate 11 is provided.

前記乗りかごは、かご室１２と、前記かご室１２の前面に開閉自在に設けられたかご戸１３と、前記かご室１２の下部に取付けられたかご床１４と、前記かご室前面下部に装着されたかご敷居１５とを主要素として構成され、前記かご床１４は床支持枠５ａ及び防振ゴム５ｂを介して前記かご枠下梁５に支持されている。この時、前記かご室１２の奥行き方向と前記かご枠下梁５の長手方向とは直交しており、また、前記乗りかごの重心は、前記かご枠下梁５を構成する枠材対の長手方向中心線上にあるように配置されている。   The car is mounted on a car room 12, a car door 13 provided on the front surface of the car room 12 so as to be freely opened and closed, a car floor 14 attached to the lower part of the car room 12, and a lower front part of the car room. The car sill 15 is configured as a main element, and the car floor 14 is supported by the car frame lower beam 5 via a floor support frame 5a and a vibration isolating rubber 5b. At this time, the depth direction of the car room 12 and the longitudinal direction of the car frame lower beam 5 are orthogonal to each other, and the center of gravity of the car is the length of the pair of frame members constituting the car frame lower beam 5. It is arranged so that it is on the direction center line.

前記かご室１２の幅寸法を、前記かご枠の内法幅寸法よりも小さくすることにより、前記かご室１２両側壁及び前記かご床１４両側壁と、左右の前記かご枠縦柱３との間に間隙を設けている。
前記かご枠下梁５の左右には吊車１６が回転自在に軸着されており、従って、前記かご枠下梁５は従来の吊車取付梁として兼用されている。主索１７は、鉛直上方より前記かご枠上梁４を構成する枠材対の間を通し、次いで前記かご室１２側壁及び前記かご床１４側壁と前記かご枠縦柱３との間隙を通して、更に前記かご枠下梁５を構成する枠材対の間を通した上で、前記かご枠下梁５に軸着された左右の前記吊車１６に順に巻き掛けられて方向転換され、今度は前述とは逆の順序で、すなわち、下方より前記かご枠下梁５を構成する枠材対の間を通し、前記かご室１２側壁及び前記かご床１４側壁と前記かご枠縦柱３との間隙を通し、前記かご枠上梁４を構成する枠材対の間を通して引き回されている。 By making the width dimension of the car room 12 smaller than the internal width dimension of the car frame, the car room 12 side walls and the car floor 14 both side walls and the left and right car frame vertical pillars 3 Is provided with a gap.
Suspension wheels 16 are rotatably mounted on the left and right sides of the car frame lower beam 5, so that the car frame lower beam 5 is also used as a conventional suspension car mounting beam. The main rope 17 passes between the frame material pair constituting the car frame upper beam 4 from above vertically, and then passes through the gap between the car chamber 12 side wall and the car floor 14 side wall and the car frame vertical column 3. After passing between a pair of frame members constituting the car frame lower beam 5, it is wound around the left and right suspension wheels 16 that are pivotally attached to the car frame lower beam 5, and the direction is changed. Are passed in the reverse order, that is, from below, between the pair of frame members constituting the car frame lower beam 5 and through the gap between the car room 12 side wall and the car floor 14 side wall and the car frame vertical column 3. The car frame upper beam 4 is routed between a pair of frame members.

以上のように構成されたエレベータのかご吊車取付装置においては、専用の吊車取付梁は不要であり、ピット深さを浅くすることができ、かつ、軽量化された乗りかごを従来より安価に得ることができる。更に、乗りかごの重心と、ガイドレールが乗りかごを支持する支持点と、主索が乗りかごを吊る吊点とが一致するため、偏荷重がかからずガイドレール及びガイドシューの磨耗を抑え、かつ、非常止め装置作動時に吊車にかかる慣性モーメントを極小とすることができる。また、一対のガイドレールは、奥行き方向に垂直な同一平面内に配置されるため、ガイドレールとガイドシューとの交合が外れ易いということもなく、ガイドレール外れ止めも必要ない。   In the elevator car suspension vehicle mounting apparatus configured as described above, a dedicated suspension vehicle mounting beam is not required, the pit depth can be reduced, and a lighter passenger car can be obtained at a lower cost than before. be able to. In addition, the center of gravity of the car, the support point where the guide rail supports the car, and the hanging point where the main rope suspends the car match, so there is no uneven load and wear of the guide rail and guide shoe is suppressed. In addition, the moment of inertia applied to the suspended vehicle when the emergency stop device is activated can be minimized. Further, since the pair of guide rails are arranged in the same plane perpendicular to the depth direction, the guide rail and the guide shoe are not easily disconnected from each other, and the guide rail does not need to be detached.
