Description

工事用エレベーター装置Elevator equipment for construction
　本発明は、工事用のエレベーター装置に関する。 The present invention relates to an elevator device for construction work.
　従来の工事用エレベーター装置の例は、特許文献１に記載されている。特許文献１に記載された工事用エレベーター装置は、建屋の昇降路内に設置された支持部材と、支持部材の下方に配置されて昇降路内を昇降方向に移動可能な機械室ユニットと、支持部材に支持されて機械室ユニットを昇降方向に移動させる機械室ユニット用揚重機と、機械室ユニットの下方に吊り下げられたかごを備える。支持部材は、支持部材の上方に設けられた第二の支持部材から吊られており、第二の支持部材に設置された揚重機によって昇降方向に移動可能である。支持部材は、昇降路の壁に向かう方向に伸縮可能な伸縮支持部を備え、この伸縮支持部が伸長することにより建屋に固定され、機械室ユニットとかごの重量を支持する。 An example of a conventional elevator device for construction work is described in Patent Document 1. The construction elevator device described in Patent Document 1 includes a support member installed in the hoistway of a building, a machine room unit arranged below the support member and capable of moving in the hoistway in the ascending / descending direction, and a support. It is provided with a lifting machine for the machine room unit that is supported by a member and moves the machine room unit in the elevating direction, and a car suspended below the machine room unit. The support member is suspended from a second support member provided above the support member, and can be moved in the elevating direction by a lifting machine installed on the second support member. The support member includes a telescopic support portion that can be expanded and contracted in the direction toward the wall of the hoistway, and the telescopic support portion is extended to be fixed to the building to support the weight of the machine room unit and the car.

　本実施例による工事用エレベーター装置の通常の運転時、すなわち、かご２を昇降させるときには、機械室ユニット４は、伸縮支持部６によって昇降路１の壁に固定されている。この期間中、エレベーター据付工事の作業者は、作業プラットフォーム１１に乗り込み、ガイドレール７や昇降路１内の機器（図示は省略した）の据付作業を行う。また、作業者は、機械室ユニット４を上方に移動させるために、機械室ユニット４を吊り下げて支持している支持部材９を上方に移動させる。 During normal operation of the construction elevator device according to this embodiment, that is, when raising and lowering the car 2, the machine room unit 4 is fixed to the wall of the hoistway 1 by the telescopic support portion 6. During this period, the elevator installation worker gets on the work platform 11 and installs the equipment (not shown) in the guide rail 7 and the hoistway 1. Further, in order to move the machine room unit 4 upward, the operator moves the support member 9 that suspends and supports the machine room unit 4 upward.
　作業者が伸縮支持部１３を短縮させて支持部材９を上方に移動させると、ガイドシュー１４ａ、１４ｂは、それぞれかご用ガイドレール７ａ、７ｂに案内され、ガイドシュー１４ｃ、１４ｄは、それぞれ釣り合いおもり用ガイドレール７ｃ、７ｄに案内されて、上方に移動する。このため、支持部材９は、ガイドシュー１４によってガイドレール７に案内されて、向きが一定のままで安全に垂直に移動することができる。 When the operator shortens the telescopic support portion 13 and moves the support member 9 upward, the guide shoes 14a and 14b are guided by the car guide rails 7a and 7b, respectively, and the guide shoes 14c and 14d are balanced weights, respectively. Guided by the guide rails 7c and 7d, it moves upward.

　さらに、本実施例による工事用エレベーター装置では、支持部材９の移動中に何らかの理由で支持部材９が落下したときに、非常止め部１５によって支持部材９の落下を防止でき、安全性をより向上させることができる。 Further, in the construction elevator device according to the present embodiment, when the support member 9 falls for some reason while the support member 9 is moving, the emergency stop portion 15 can prevent the support member 9 from falling, further improving safety. Can be made to.
　図４は、支持部材９が備えるガイドシュー１４と非常止め部１５を示す図であり、支持部材９が静止しているときの図である。 FIG. 4 is a diagram showing a guide shoe 14 and an emergency stop portion 15 included in the support member 9, and is a diagram when the support member 9 is stationary.
　ガイドシュー１４は、上述したように、ガイドレール７に嵌合する。 The guide shoe 14 fits into the guide rail 7 as described above.
　非常止め部１５は、ガイドレール７を挟んで互いに対向する、それぞれ一対のウェッジ２１とローラ２２とウェッジガイド２４を備える。ウェッジ２１は、支持部材９に対して、かご２の昇降方向に移動可能な楔型部材であり、図示しないウェッジ引き上げ部によって引き上げられる。ウェッジ引き上げ部は、例えば、作業プラットフォーム１１に乗り込んだ作業者が操作する引き上げロッドで構成することができる。ローラ２２とウェッジガイド２４は、ウェッジ２１の、かご２の昇降方向への移動を案内する案内部材であり、支持部材９に固定されている。ウェッジガイド２４は、ウェッジ２１に設けられた切り欠きに嵌合する板状部材である。ウェッジ２１は、ローラ２２とウェッジガイド２４に対して上方に移動できる。 The emergency stop portion 15 includes a pair of wedges 21, rollers 22, and wedge guides 24, which face each other with the guide rail 7 in between. The wedge 21 is a wedge-shaped member that can move in the elevating direction of the car 2 with respect to the support member 9, and is pulled up by a wedge pulling portion (not shown). The wedge pulling portion can be composed of, for example, a pulling rod operated by an operator who has boarded the work platform 11. The rollers 22 and the wedge guide 24 are guide members for guiding the movement of the wedge 21 in the elevating direction of the car 2, and are fixed to the support member 9. The wedge guide 24 is a plate-shaped member that fits into the notch provided in the wedge 21. The wedge 21 can move upward with respect to the roller 22 and the wedge guide 24.
　一対のウェッジ２１は、ウェッジ引き上げ部によって引き上げられると、ローラ２２とウェッジガイド２４に案内され、形状が楔型であるので上方にかつガイドレール７に近づく向きに移動し、ガイドレール７を挟むことができる。 When the pair of wedges 21 are pulled up by the wedge pulling portion, they are guided by the roller 22 and the wedge guide 24, and since the shape is wedge-shaped, they move upward and in a direction approaching the guide rail 7, and sandwich the guide rail 7. Can be done.
　図５は、支持部材９が備えるガイドシュー１４と非常止め部１５を示す図であり、支持部材９が上方に移動しているときの図である。 FIG. 5 is a diagram showing a guide shoe 14 and an emergency stop portion 15 included in the support member 9, and is a diagram when the support member 9 is moving upward.
　支持部材９を上方に移動させるときは、作業者がウェッジ２１をウェッジ引き上げ部で引き上げてウェッジ２１をガイドレール７に接触させ、ウェッジ２１がガイドレール７に接触した状態のままで支持部材９を移動させる。すなわち、支持部材９が上方に移動しているときは、ウェッジ２１は、ガイドレール７に接触している。但し、ウェッジ２１は、支持部材９が移動できるように、ガイドレール７を強い力で挟んでおらず、ガイドレール７に単に接触しているだけである。 When moving the support member 9 upward, the operator pulls up the wedge 21 with the wedge pulling portion to bring the wedge 21 into contact with the guide rail 7, and the support member 9 is moved while the wedge 21 is in contact with the guide rail 7. Move. That is, when the support member 9 is moving upward, the wedge 21 is in contact with the guide rail 7. However, the wedge 21 does not sandwich the guide rail 7 with a strong force so that the support member 9 can move, but merely contacts the guide rail 7.
　支持部材９が上方に移動中に何らかの理由で落下すると、ウェッジ２１は、ガイドレール７に接触しているので、ガイドレール７との間の摩擦力によって下方に移動せず、ローラ２２とウェッジガイド２４は、下方に移動する。すると、ウェッジ２１は、ローラ２２とウェッジガイド２４に対して上方に移動し、ローラ２２とウェッジガイド２４に案内されて、ガイドレール７を強い力で挟む（図５において、一対のウェッジ２１が更にガイドレール７に近づく）。ウェッジ２１は、支持部材９が落下すると、このようにして速やかにガイドレール７を強固に把持し、支持部材９の落下を停止させる。 If the support member 9 falls for some reason while moving upward, the wedge 21 is in contact with the guide rail 7 and therefore does not move downward due to the frictional force between the support member 9 and the roller 22 and the wedge guide. 24 moves downward. Then, the wedge 21 moves upward with respect to the roller 22 and the wedge guide 24, is guided by the roller 22 and the wedge guide 24, and sandwiches the guide rail 7 with a strong force (in FIG. 5, the pair of wedges 21 further sandwiches the guide rail 7). Approaching the guide rail 7). When the support member 9 falls, the wedge 21 promptly and firmly grips the guide rail 7 in this way to stop the fall of the support member 9.
　以上説明したように、本実施例による工事用エレベーター装置は、非常止め部１５によって支持部材９の落下を防止でき、支持部材９を安全に上方に移動させることができる。 As described above, in the construction elevator device according to the present embodiment, the emergency stop portion 15 can prevent the support member 9 from falling, and the support member 9 can be safely moved upward.
　さらに、本実施例による工事用エレベーター装置では、機械室ユニット４を移動させるときに、支持部材９から建屋（昇降路１の壁）に加わる荷重を小さくでき、支持部材９を支持する建屋に加わる負担を軽減することができる。高層の建屋では、工事用エレベーター装置が大型化し、支持部材９が支持する機械室ユニット４やかご２などの重量が大きい。このため、機械室ユニット４を移動させるときに、支持部材９が伸縮支持部１３のみで建屋に支持されていると、支持部材９から建屋に加わる荷重が大きく、支持部材９を支持する建屋への負担が大きい。 Further, in the construction elevator device according to the present embodiment, when the machine room unit 4 is moved, the load applied from the support member 9 to the building (the wall of the hoistway 1) can be reduced, and the load is applied to the building that supports the support member 9. The burden can be reduced. In a high-rise building, the construction elevator device becomes large, and the machine room unit 4 and the car 2 supported by the support member 9 are heavy. Therefore, when the machine room unit 4 is moved, if the support member 9 is supported by the building only by the telescopic support portion 13, the load applied from the support member 9 to the building is large, and the building supports the support member 9. Is a heavy burden.
　既に述べたように、機械室ユニット４は、支持部材９から機械室ユニット用揚重機８によって吊り下げられており、機械室ユニット用揚重機８によってかご２の昇降方向に移動可能である。 As already described, the machine room unit 4 is suspended from the support member 9 by the machine room unit lifting machine 8, and can be moved in the elevating direction of the car 2 by the machine room unit lifting machine 8.
　機械室ユニット４を上方に移動させるときには、作業者は、ウェッジ引き上げ部で、支持部材９の非常止め部１５のウェッジ２１を、ウェッジ２１がガイドレール７を強い力で挟むまで引き上げる。すると、ウェッジ２１は、ガイドレール７を強固に把持する（図５において、一対のウェッジ２１が更にガイドレール７に近づく）。支持部材９は、機械室ユニット４が上方に移動しているときは、一対のウェッジ２１がガイドレール７を挟んで把持していることでガイドレール７に固定され、機械室ユニット４やかご２などの重量を支持する。ガイドレール７に支持部材９が固定されると、ガイドレール７は、支持部材９に加わる荷重の一部を受けることができる。 When moving the machine room unit 4 upward, the operator pulls up the wedge 21 of the emergency stop portion 15 of the support member 9 with the wedge pulling portion until the wedge 21 sandwiches the guide rail 7 with a strong force. Then, the wedge 21 firmly grips the guide rail 7 (in FIG. 5, the pair of wedges 21 further approaches the guide rail 7). When the machine room unit 4 is moving upward, the support member 9 is fixed to the guide rail 7 by being gripped by a pair of wedges 21 sandwiching the guide rail 7, and the machine room unit 4 or the car 2 is fixed. Support weight such as. When the support member 9 is fixed to the guide rail 7, the guide rail 7 can receive a part of the load applied to the support member 9.
　本実施例による工事用エレベーター装置では、機械室ユニット４が上方に移動しているときに、支持部材９を建屋とガイドレール７で支持することができるので、支持部材９から建屋に加わる荷重を小さくでき、建屋の負担を軽減することができる。 In the construction elevator device according to the present embodiment, when the machine room unit 4 is moving upward, the support member 9 can be supported by the building and the guide rail 7, so that the load applied from the support member 9 to the building can be applied. It can be made smaller and the burden on the building can be reduced.
　本発明の実施例２による工事用エレベーター装置について説明する。本実施例による工事用エレベーター装置は、実施例１による工事用エレベーター装置と同様の構成を備えるが、釣り合いおもり３と釣り合いおもり用ガイドレール７ｃ、７ｄの位置と、支持部材９の構成が、実施例１による工事用エレベーター装置と異なる。以下では、本実施例による工事用エレベーター装置について、実施例１による工事用エレベーター装置と異なる点を主に説明する。 The construction elevator device according to the second embodiment of the present invention will be described. The construction elevator device according to the present embodiment has the same configuration as the construction elevator device according to the first embodiment, but the positions of the equilibrium weight 3 and the counterweight guide rails 7c and 7d and the configuration of the support member 9 are implemented. It is different from the construction elevator device according to Example 1. Hereinafter, the construction elevator device according to the present embodiment will be mainly described as being different from the construction elevator device according to the first embodiment.
　図３は、本発明の実施例２による工事用エレベーター装置の支持部材９を示す平面図である。本実施例による工事用エレベーター装置では、かご用ガイドレール７ａ、７ｂが互いに対向する向きが、釣り合いおもり用ガイドレール７ｃ、７ｄが互いに対向する向きと異なっており、これらの向きは互いに直交する。 FIG. 3 is a plan view showing a support member 9 of the construction elevator device according to the second embodiment of the present invention.
