Abstract

【課題】循環式エレベーターの使用にも耐えられるような強力な懸垂用チェインを提供する。
【解決手段】チェインの構成部品として通常用いられている外リンクプレート９の内、所要個数を溝形外リンク５に取り替えてその側面中央部を突き出して負荷懸垂用軸７を設け、溝形外リンク５の脚部６をチェインホイール１０の歯部１１の根元に設けたタイヤ部１２の両側面に嵌合させた状態で、タイヤ部１２の円周面に載せることにより負荷懸垂用軸７に取り付けられた荷重を支えると共に、チェインの中心線より外れているこの荷重によるチェインの危険な傾きに耐えうるようにした懸垂用チェインを開発する。懸垂用チェインの直線運行区間において、懸垂用チェインの溝形外リンク５の溝側の内凹面にハット形の長尺案内材、そして背面には平滑面の長尺案内材を沿わせて、外力に起因する運行時の蛇行を防ぎうるようにした懸垂用チェインの案内通路を設ける。
【選択図】図１A powerful suspension chain that can withstand the use of a circulating elevator.
Of the outer link plates that are usually used as chain components, the required number is replaced with a groove-shaped outer link, and a load suspension shaft is provided by projecting the center of the side surface. In a state where the leg portions 6 of the links 5 are fitted to both side surfaces of the tire portion 12 provided at the root of the tooth portion 11 of the chain wheel 10, the load suspension shaft 7 is mounted on the circumferential surface of the tire portion 12. Develop a suspension chain that supports the attached load and that can withstand the dangerous tilt of the chain due to this load being off the centerline of the chain. In the linear operation section of the suspension chain, a long guide material with a hat shape is placed on the inner concave surface of the groove-shaped outer link 5 of the suspension chain, and a long guide material with a smooth surface is placed on the rear surface. A suspension chain guide passage is provided so as to prevent meandering during operation due to the operation.

Description

本案の懸垂用チェインは循環式エレベーター用及び物品を水平又は垂直に懸垂しで運行する搬送用機械に使用される。  The suspension chain of the present proposal is used for a circulating elevator and a transporting machine that operates articles suspended horizontally or vertically.

現在外リンクプレートの側面に重量物を懸垂して搬送する用途に適応したチェインは見当たらない。  There are currently no chains that are suitable for applications in which heavy objects are suspended from the side of the outer link plate.

循環式エレベーターのように重量物の籠をチェインホイールにより引き上げ、その頂点を循環させる動作に適応できる強力な構造の懸垂用チェインは未開発である。本案はこれを満足させる強度をチェインに持たせる。  A suspension chain with a strong structure that can be adapted to the operation of lifting a heavy load by a chain wheel and circulating the apex of it like a circulating elevator has not been developed yet. This proposal gives the chain the strength to satisfy this.

その上、本案の懸垂チェインの外力に起因する運行時の蛇行を防ぐための案内通路を附属させる。  In addition, a guide passage is attached to prevent meandering during operation due to the external force of the suspension chain of this plan.

チェインの構造部品として通常用いられている外リンクプレート９の内、所要個数を溝形外リンク５に取り替えてその側面中央部を突き出して負荷懸垂用軸７を設け、又、溝形外リンク５の脚部６をチェインホイール１０の歯部１１の根元に設けたタイヤ部１２の両側面に嵌合させた状態で、タイヤ部１２の円周面に載せることにより負荷懸垂用軸７に取り付けられた荷重を支えると共に、チェインの中心線より外れているこの荷重によるチェインの危険な傾きに耐えうるようにする。  The required number of outer link plates 9 usually used as the structural parts of the chain is replaced with a groove-shaped outer link 5, and the load suspension shaft 7 is provided by projecting the central portion of the side surface. Are attached to the load suspension shaft 7 by being placed on the circumferential surface of the tire portion 12 in a state where the leg portions 6 are fitted to both side surfaces of the tire portion 12 provided at the root of the tooth portion 11 of the chain wheel 10. And to withstand the dangerous tilt of the chain due to this load being off the center line of the chain.

懸垂用チェインの直線運行区間において、懸垂用チェインの溝形外リンク５の溝側の内凹面にハット形の長尺案内材１４、そして背面には平滑面の長尺案内材１５を沿わせて、外力に起因する運行時の蛇行を防ぎうるようにする。  In the linear operation section of the suspension chain, a hat-shaped long guide member 14 is placed on the inner concave surface of the suspension chain outer link 5 on the groove side, and a smooth long guide member 15 is placed on the back surface. To prevent meandering during operation caused by external force.

本案の懸垂用チェインの開発により多数の籠を取り付けて循環するエレベーターのように大きな荷重に耐え、その上安全性の要求に応えることが出来、従来のロープ懸垂式エレベーターに比し、格段に安全度の高いエレベーターが期待できる。  With the development of the suspension chain of this proposal, it can withstand a large load like an elevator that circulates with a large number of kites, and can meet the safety demands. It is much safer than conventional rope suspension elevators. A high-level elevator can be expected.

図１及び図２は本考案の懸垂用チェインがチェインホイール１０に噛み合った状態の実施の一例であって、外リンクプレート９は内プレートリンク４の外側に分離した２枚のプレートとして取り付けられているため、これに垂直用軸を取り付けても到底、大きな負荷には耐えられない。そのため本案では一対の外リンクプレート９の代わりに外リンクを溝形の一体形とし、その側面中央部に鍛造により、たたき出して負荷懸垂用軸７を設け、溝形外リンク５の脚部６の内面をチェインホイール１０の歯部１１の根元に設けたタイヤ部１２の両側面にあまり隙間なく嵌合させることにより、溝形リンク６が負荷によりチェインホイール１０から傾くことを防止すると共にその脚部６がタイヤ部１２の円周面に載り、これに荷重を負わせることが出来る。このようにしてチェインの危険な傾きに耐えうるようにする。  FIG. 1 and FIG. 2 show an example of the suspension chain according to the present invention in an engaged state with the chain wheel 10, and the outer link plate 9 is attached to the outside of the inner plate link 4 as two separate plates. Therefore, even if a vertical shaft is attached to this, it cannot withstand a large load. Therefore, in this proposal, instead of the pair of outer link plates 9, the outer link is formed into a groove-shaped integral, and the load suspension shaft 7 is provided by forging at the center of the side surface of the outer link plate 9. By fitting the inner surface to both side surfaces of the tire portion 12 provided at the root of the tooth portion 11 of the chain wheel 10 without much gap, the groove-shaped link 6 is prevented from being inclined from the chain wheel 10 due to a load and its leg portion. 6 is placed on the circumferential surface of the tire portion 12, and a load can be applied to this. In this way it will be able to withstand the dangerous tilt of the chain.

図３、図４及び図５は本考案の懸垂用チェインが直線運行区間において外力により、例えば地震等によりゆり起こされ、波打つ状態になることを防ぐために案内通路を設けるものである。チェインの波打つ状態はエレベーターに使用されるとき絶対に避けるべき現象である。本案の懸垂用チェインには負荷懸垂用軸７も設けた溝形リンク５以外にこの懸垂用軸７を取り付けていない溝形外リンク５を通常の外リンクプレート９の数個の間に、図３のように介在させることにより、溝形外リンク５の溝側の内凹面に嵌りこむようにハット形の長尺案内材１４を少し隙間をあけて配置し、又溝形外リンク５の背面の平面部に平滑面の長尺案内材１５を少し隙間をあけて配置し、これらを架台から支持腕１６により支えられている。従って本案の懸垂用チェインは地震等の外力によっても円滑な運行を続けることができる。  3, 4, and 5 are provided with a guide passage to prevent the suspension chain according to the present invention from being swayed by an external force, such as an earthquake, in a straight traveling section. Chain rippling is a phenomenon that should be avoided when used in elevators. In addition to the groove-shaped link 5 provided with the load suspension shaft 7 in the suspension chain of the present proposal, the groove-shaped outer link 5 to which the suspension shaft 7 is not attached is disposed between several ordinary outer link plates 9. 3, the hat-shaped long guide member 14 is arranged with a slight gap so as to fit into the inner concave surface of the groove-shaped outer link 5 on the groove side. A long guide material 15 having a smooth surface is arranged on the flat surface with a little gap, and these are supported by a support arm 16 from a gantry. Therefore, the suspension chain of the present plan can continue to operate smoothly even by an external force such as an earthquake.
