また、昇降路１の天井部１ａには、それぞれ金属棒材をＵ字状に曲成してなる一対の掛け部材６，７が一定の間隔をあけて取り付けられている。そして一方の掛け部材６の内側に滑車装置１０が設けられている。   In addition, a pair of hanging members 6 and 7 each formed by bending a metal bar into a U shape are attached to the ceiling portion 1a of the hoistway 1 with a certain interval. A pulley device 10 is provided inside one of the hanging members 6.

滑車装置１０の構造を図２及び図３に示してある。図２は滑車装置１０の側面図で、図３は滑車装置１０の平面図である。滑車装置１０は本体１１を備え、この本体１１は互いに対向する一対の側板１２を鋼材１３で一体的に結合してなる。本体１１は水平部１１ａと垂直部１１ｂとを有するほぼＬ形状をなし、その水平部１１ａと垂直部１１ｂとが交差する部分の両側外面には鋼材１４が取り付けられ、その一方の鋼材１４の外面から前記両側板１２を貫通して他方の鋼材１４の外面側に達する滑車ボルト１５が設けられ、この滑車ボルト１５を介して両側板１２間に一対の滑車１８が並列するようにそれぞれ回転自在に支持されている。なお、１６は前記滑車ボルト１５の先端部に螺着されたナットである。   The structure of the pulley device 10 is shown in FIGS. FIG. 2 is a side view of the pulley device 10, and FIG. 3 is a plan view of the pulley device 10. The pulley device 10 includes a main body 11, and the main body 11 is formed by integrally joining a pair of side plates 12 facing each other with a steel material 13. The main body 11 has a substantially L shape having a horizontal portion 11a and a vertical portion 11b, and steel materials 14 are attached to both side outer surfaces of a portion where the horizontal portion 11a and the vertical portion 11b intersect, and the outer surface of one steel material 14 Is provided with pulley bolts 15 penetrating the both side plates 12 and reaching the outer surface side of the other steel material 14, and a pair of pulleys 18 are rotatably arranged in parallel between the side plates 12 via the pulley bolts 15. It is supported. Reference numeral 16 denotes a nut screwed to the tip of the pulley bolt 15.

本体１１における垂直部１１ｂの下部にはフック部材２０が設けられている。このフック部材２０は図４に示すように両側板１２間に設けられた断面コ字状の鋼材２１を介してその両側板１２間に配置するように支持されている。断面コ字状の鋼材２１は支持軸２２を介して両側板１２に対して回動自在に取り付けられ、フック部材２０の下端部は鋼材２１に摺動自在に貫挿され、その下側にナット２３が螺着され、フック部材２０の全体が鋼材２１と一体的に支持軸２２を中心としてその軸回り方向に回動することが可能となっている。   A hook member 20 is provided below the vertical portion 11 b of the main body 11. As shown in FIG. 4, the hook member 20 is supported so as to be disposed between both side plates 12 through a steel material 21 having a U-shaped cross section provided between the both side plates 12. A steel material 21 having a U-shaped cross section is rotatably attached to both side plates 12 via a support shaft 22, and a lower end portion of the hook member 20 is slidably inserted into the steel material 21, and a nut is provided below the steel member 21. 23 is screwed, and the entire hook member 20 can be rotated integrally with the steel material 21 around the support shaft 22 in the direction around the axis.

滑車装置１０を掛け部材６に取り付ける手順について説明すると、まず図２に示すように、本体１１の水平部１１ａをＵ字状の掛け部材６の内側に挿入し、この状態で本体１１の垂直部１１ｂに設けられているフック部材２０を回動してその先端部を掛け部材６の下端部に掛け止めるとともに、ナット２３を締め付け、フック部材２０を軸方向に移動させて本体１１の水平部１１ａの上面を昇降路１の天井部１ａに押し付けて圧着させる。これにより滑車装置１０の全体が昇降路１の天井部１ａに強固にかつ安定して固定されている。   The procedure for attaching the pulley device 10 to the hanging member 6 will be described. First, as shown in FIG. 2, the horizontal portion 11a of the main body 11 is inserted inside the U-shaped hanging member 6, and in this state, the vertical portion of the main body 11 is inserted. The hook member 20 provided on 11b is rotated so that its tip end is hooked on the lower end of the hooking member 6, and the nut 23 is tightened to move the hook member 20 in the axial direction so that the horizontal portion 11a of the main body 11 is moved. Is pressed against the ceiling portion 1a of the hoistway 1 for pressure bonding. Thereby, the whole pulley apparatus 10 is firmly and stably fixed to the ceiling portion 1 a of the hoistway 1.

このように、昇降路１の天井部１ａに設けられた掛け部材６の内側に滑車装置１０を取り付けた後には、この滑車装置１０の滑車１８に図１に示すように揚重用線条材としての玉掛けワイヤ２７を巻き掛ける。そしてこの玉掛けワイヤ２７の一端部をエレベータ用品としての巻上機３１に連結し、他端部を揚重機３０に連結する。揚重機３０の吊元側のワイヤ３２は、昇降路１の側壁面に設けられている吊元部３３に掛け止める。   Thus, after attaching the pulley apparatus 10 to the inner side of the hanging member 6 provided on the ceiling portion 1a of the hoistway 1, the pulley 18 of the pulley apparatus 10 is used as a lifting wire as shown in FIG. Wrap the slack wire 27. One end of the sling wire 27 is connected to a hoisting machine 31 as an elevator article, and the other end is connected to a lifting machine 30. The wire 32 on the suspension side of the lifting machine 30 is hooked on a suspension portion 33 provided on the side wall surface of the hoistway 1.

この状態で、揚重機３０を操作して玉掛けワイヤ２７を揚重機３０側に引き込み、巻上機３１を昇降路１の上部に向けて吊り上げる。そして巻上機３１がマシンベット５より上方の位置にまで達した際に揚重機３０の操作を停止し、マシンベット５の上に巻上機３１を乗せる。巻上機３１を横にずらすことが必要なときには、巻上機３１をマシンベット５に沿って移動させる。巻上機３１が所定の位置に配置された後には、ボルトやクリップなどの締結部品を用いて巻上機３１をマシンベット５に据え付けて固定し、巻上機３１から玉掛けワイヤ２７を取り外す。   In this state, the lifting machine 30 is operated to draw the sling wire 27 toward the lifting machine 30, and the hoisting machine 31 is lifted toward the upper part of the hoistway 1. When the hoisting machine 31 reaches a position above the machine bed 5, the operation of the lifting machine 30 is stopped and the hoisting machine 31 is placed on the machine bed 5. When it is necessary to shift the hoisting machine 31 to the side, the hoisting machine 31 is moved along the machine bed 5. After the hoisting machine 31 is disposed at a predetermined position, the hoisting machine 31 is installed and fixed to the machine bed 5 using fastening parts such as bolts and clips, and the sling wire 27 is removed from the hoisting machine 31.

このような揚重形態においては、巻上機３１の吊上頂部となる滑車１８が昇降路１の天井部１ａに設けられている掛け部材６の内側に配置されて天井部１ａの間近にあり、このため巻上機３１を天井部１ａの至近距離まで吊り上げて巻上機３１を天井部１ａの間近の最上部に据え付けることができる。なお、巻上機３１の場合のほか、他のエレベータ用品についても同様に吊り上げることができる。   In such a lifting configuration, the pulley 18 that is the top of the hoisting machine 31 is disposed inside the hanging member 6 provided on the ceiling 1a of the hoistway 1 and is close to the ceiling 1a. For this reason, the hoisting machine 31 can be lifted up to a close distance of the ceiling part 1a and the hoisting machine 31 can be installed on the uppermost part near the ceiling part 1a. In addition to the hoisting machine 31, other elevator equipment can be lifted in the same manner.

図５及び図６にはこの発明の第２の実施形態に滑車装置１０の構造を示してある。図５はその滑車装置１０の側面図で、図６は同じく平面図である。この滑車装置１０は、ベース３６を備え、このベース３６の上に３つの支持板３７，３８，３９がそれぞれ互いに離間して対向するようにボルト４０を介して取り付けられている。支持板３７，３８間には滑車ボルト４１が架設され、この滑車ボルト４１を介して支持板３７，３８間において一対の滑車４２がそれぞれ回転自在に支持されている。   5 and 6 show the structure of the pulley apparatus 10 according to the second embodiment of the present invention. FIG. 5 is a side view of the pulley apparatus 10 and FIG. 6 is a plan view of the same. The pulley apparatus 10 includes a base 36, and three support plates 37, 38, and 39 are attached to the base 36 via bolts 40 so as to face each other while being separated from each other. A pulley bolt 41 is installed between the support plates 37 and 38, and a pair of pulleys 42 are rotatably supported between the support plates 37 and 38 via the pulley bolt 41.

支持板３８，３９の一方の端面側にはその支持板３８，３９の双方に跨って配置するように当板４４が設けられている。この当板４４はそれぞれボルト４５を介して支持板３８，３９の端面に着脱可能に取り付けられている。そしてこの当板４４の内側にＵボルト４７を取り付けることができるようになっている。   A contact plate 44 is provided on one end face side of the support plates 38 and 39 so as to be disposed across both of the support plates 38 and 39. The contact plates 44 are detachably attached to the end surfaces of the support plates 38 and 39 via bolts 45, respectively. A U bolt 47 can be attached to the inside of the contact plate 44.

この滑車装置１０は昇降路１の天井部１ａの掛け部材６に次のような手順で取り付ける。まず、当板４４を取り外した状態で、滑車装置１０の側方側からＵ字状をなす掛け部材６の片側の垂直部を支持板３８，３９間の空間内に介入させる。次に、前記支持板３８，３９の端面に当板４４を突き当て、この当板４４をボルト４５で支持板３８，３９の端面に締結して固定する。次に、当板４４の内側から前記掛け部材６の垂直部を抱え込むようにＵボルト４７を挿入し、その挿入側の端部にナット４８を螺着し、これらナット４８を締め付け、Ｕボルト４７と当板４４とで掛け部材６の垂直部を挟み込んで締め付ける。これにより、滑車装置１０が掛け部材６の垂直部に水平に取り付けられ、滑車４２が掛け部材６の下端部より上方に位置に配置される。   This pulley apparatus 10 is attached to the hanging member 6 of the ceiling portion 1a of the hoistway 1 in the following procedure. First, with the abutment plate 44 removed, a vertical portion on one side of the U-shaped hanging member 6 from the side of the pulley apparatus 10 is inserted into the space between the support plates 38 and 39. Next, the contact plate 44 is abutted against the end surfaces of the support plates 38 and 39, and the contact plate 44 is fastened and fixed to the end surfaces of the support plates 38 and 39 with bolts 45. Next, a U bolt 47 is inserted from the inside of the abutment plate 44 so as to hold the vertical portion of the hanging member 6, a nut 48 is screwed to an end portion on the insertion side, the nut 48 is tightened, and the U bolt 47 And the vertical part of the hanging member 6 is sandwiched between the contact plate 44 and tightened. Thereby, the pulley apparatus 10 is horizontally attached to the vertical portion of the hanging member 6, and the pulley 42 is disposed at a position above the lower end portion of the hanging member 6.

このように掛け部材６に滑車装置１０を取り付けた後には、前述の場合と同様に、滑車装置１０の滑車４２に揚重用線条材としての玉掛けワイヤ２７を巻き掛け、その玉掛けワイヤ２７の一端部を揚重対象物であるエレベータ用品に連結し、他端部を揚重機に連結する。そして揚重機を操作してエレベータ用品を吊り上げる。   After the pulley device 10 is attached to the hanging member 6 as described above, a sling wire 27 as a lifting wire is wound around the pulley 42 of the pulley device 10 in the same manner as described above, and one end of the sling wire 27 is wound. The part is connected to an elevator article that is a lifting object, and the other end is connected to a lifting machine. Then the elevator is operated to lift the elevator equipment.

この場合においても、エレベータ用品の吊上頂部となる滑車４２が昇降路１の天井部１ａに設けられている掛け部材６の下端部より上方に配置されているから、そのエレベータ用品を天井部１ａの間近となるより高い位置にまで吊り上げて天井部１ａの間近の最上部の位置に据え付けることができる。   Also in this case, since the pulley 42 which becomes the lifting top of the elevator article is disposed above the lower end of the hanging member 6 provided on the ceiling part 1a of the hoistway 1, the elevator article is placed on the ceiling part 1a. It can be lifted to a higher position that is close to the ceiling, and can be installed at the uppermost position near the ceiling 1a.

そしてこの場合には、滑車装置１０が掛け部材６の垂直部にＵボルト４７を介して取り付けられているため、そのＵボルト４７を緩めることにより滑車装置１０の全体をその掛け部材６の垂直部の軸回り方向に回動してその向きを変えることができる。したがって、エレベータ用品を吊り上げる揚重方向が変わるような場合であってもそれに容易に対応することができる。   In this case, since the pulley device 10 is attached to the vertical portion of the hanging member 6 via the U bolt 47, the entire pulley device 10 is moved to the vertical portion of the hanging member 6 by loosening the U bolt 47. It can be rotated around its axis to change its orientation. Therefore, even when the lifting direction in which the elevator article is lifted changes, it can be easily handled.

図７乃至図９にはこの発明の第３の実施形態に係る滑車装置１０の構造を示してある。図７はその滑車装置１０の平面図、図８は同じく正面図、図９は同じく側面図である。   7 to 9 show the structure of a pulley apparatus 10 according to a third embodiment of the present invention. FIG. 7 is a plan view of the pulley apparatus 10, FIG. 8 is a front view, and FIG. 9 is a side view.

この滑車装置１０は一対の側板５０を有する本体５１を備えている。各側板５０は、それぞれ水平部５０ａと垂直部５０ｂとを有する断面Ｌ字状に形成され、その各側板５０の水平部５０ａがそれぞれ外側を向き、垂直部５０ｂが互いに対向する状態でその両垂直部５０ｂ間に２本の滑車ボルト５２が架設され、これら滑車ボルト５２で両側板５０が互いに連結されて一体的な本体５１として組み立てられている。そして前記各滑車ボルト５２にそれぞれ滑車５３が回転自在に設けられている。   The pulley apparatus 10 includes a main body 51 having a pair of side plates 50. Each side plate 50 is formed in an L-shaped cross section having a horizontal portion 50a and a vertical portion 50b. The horizontal portions 50a of the side plates 50 face outward and the vertical portions 50b face each other. Two pulley bolts 52 are installed between the portions 50 b, and both side plates 50 are connected to each other by these pulley bolts 52 to be assembled as an integral main body 51. A pulley 53 is rotatably provided on each pulley bolt 52.

各側板５０における水平部５０ａの先端縁の中間部及び垂直部５０ｂの下端縁の中間部にはそれぞれ切欠部５４，５５が形成されている。また、また各側板５０における水平部５０ａの両端寄りの部分にはその下面側から押しボルト５６が垂直に螺挿され、これら押しボルト５６にはそれぞれ緩み止め用のナット５７が螺着されている。   In each side plate 50, notches 54 and 55 are formed in the middle portion of the front edge of the horizontal portion 50a and the middle portion of the lower end edge of the vertical portion 50b, respectively. In addition, push bolts 56 are vertically screwed into the side plates 50 near the both ends of the horizontal portion 50a from the lower surface side, and nuts 57 for preventing loosening are screwed to the push bolts 56, respectively. .

この滑車装置１０は昇降路１の天井部１ａの掛け部材６に次のような手順で取り付ける。まず、本体５１をＵ字状をなす掛け部材６の内側に挿入する。この際、各側板５０がやや傾く姿勢で本体５１を掛け部材６の内側に挿入する。そして挿入後に、本体５１を正立させ、切欠部５４を掛け部材６の垂直部に嵌合させ、切欠部５５を掛け部材６の下端部に嵌合させる。次に、各押しボルト５６を工具を用いて回し、その先端を昇降路１の天井部１ａに圧接させる。この後、各ナット５７を締め付けて各押しボルト５６の緩み止めを図る。   This pulley apparatus 10 is attached to the hanging member 6 of the ceiling portion 1a of the hoistway 1 in the following procedure. First, the main body 51 is inserted inside the hanging member 6 having a U-shape. At this time, the main body 51 is inserted inside the hanging member 6 with each side plate 50 tilted slightly.
