Description
本揭示是關於一種嚙合鍊條及使用該嚙合鍊條使可動體移動的可動體移動裝置。The present disclosure relates to an engaging chain and a movable body moving device that uses the engaging chain to move a movable body.
以往這種可動體移動裝置已知有例如專利文獻1所示的嚙合鍊條式進退作動裝置。這種嚙合鍊條式進退作動裝置中,可進退的一對嚙合鍊條(鍊條部件)隨著往前進方向移動進而相互嚙合而一體化,另一方面隨著往後退方向移動進而解除相互嚙合而分歧,藉此使升降台進行升降。Conventionally, such a movable body moving device is known as, for example, an engaging chain type forward and backward actuating device shown in Patent Document 1. In this meshing chain type forward and backward actuating device, a pair of meshing chains (chain members) that can advance and retreat are integrated as they move in the forward direction and then mesh with each other. On the other hand, they diverge as they move in the backward direction and are released from mutual meshing. As a result, the lifting platform is raised and lowered.
這種嚙合鍊條是由在嚙合鍊條的長邊方向連接的多個鏈結板所構成。詳細而言,各鏈結板具有一對銷孔。相鄰的鏈結板彼此藉由連接銷與銷孔而以能夠折彎的方式連接。各鏈結板具有平坦的鉤狀嚙合端面(嚙合面)與平坦的挫曲規制端面(卡合面)。鉤狀嚙合端面設置在鏈結板的進退方向的一端部,呈S字狀彎曲。挫曲規制端面設置在鏈結板的進退方向的其他端部,並在相對進退方向傾斜交叉的方向呈直線狀延伸。This meshing chain is composed of a plurality of link plates connected in the longitudinal direction of the meshing chain. In detail, each link plate has a pair of pin holes. Adjacent link plates are connected in a bendable manner by connecting pins and pin holes. Each link plate has a flat hook-shaped engagement end surface (engagement surface) and a flat buckling regulation end surface (engagement surface). The hook-shaped engaging end surface is provided at one end of the link plate in the advancing and retreating direction, and is curved in an S shape. The end face of the buckling regulation is provided at the other end of the link plate in the advancing and retreating direction, and extends linearly in a direction obliquely crossing with respect to the advancing and retreating direction.

發明所欲解決之課題 然而,如上述的嚙合鍊條式進退作動裝置,在一對嚙合鍊條隨著往前進方向移動而相互嚙合而一體化的狀態下,一對嚙合鍊條當中的一側的嚙合鍊條的鏈結板的鉤狀嚙合端面會與另一側的嚙合鍊條的鏈結板的鉤狀嚙合端面嚙合。Problems to be solved by the invention However, as in the above-mentioned meshing chain type forward and backward actuating device, in a state where the pair of meshing chains are meshed with each other as they move in the advancing direction, the hook of the link plate of the meshing chain on one side among the pair of meshing chains The meshing end face will mesh with the hook-shaped meshing end face of the link plate that engages the chain on the other side.
在一體化的狀態下,當對於一對嚙合鍊條在進退方向施加高的壓縮負載時,由於鏈結板的鉤狀嚙合端面是平坦的,故在鉤狀嚙合端面互相嚙合的相鄰2個鏈結板彼此會在連接銷的延伸方向滑動,導致在一體化的狀態下一對嚙合鍊條有發生挫曲之虞。因此,提升在一體化的狀態下一對嚙合鍊條的挫曲負載方面仍有改善的餘地。In the integrated state, when a high compression load is applied to a pair of engagement chains in the forward and backward directions, the hook-shaped engagement end surface of the link plate is flat, so the two adjacent chains that mesh with each other at the hook-shaped engagement end surface The knot plates can slide in the extending direction of the connecting pin, which may cause the pair of engagement chains to buckle in the integrated state. Therefore, there is still room for improvement in increasing the buckling load of a pair of engaging chains in an integrated state.
本揭示的目的在於提供一種嚙合鍊條以及可動體移動裝置,其能夠提升在鍊條部件彼此嚙合而一體化的狀態下的挫曲負載。An object of the present disclosure is to provide an engaging chain and a movable body moving device capable of lifting a buckling load in a state where chain members are engaged with each other and integrated.

此時,第1鏈結板22的第1卡合面27及第2鏈結板30的第2卡合面34是由能夠互相嵌合的凹凸面之波形的曲面所構成。因此,當第1鏈結板22的第1卡合面27與第2鏈結板30的第2卡合面34卡合時,藉由第1卡合面27與第2卡合面34凹凸嵌合,在第1卡合面27及第2卡合面34的延伸方向的第1鏈結板22與第2鏈結板30之間的位置偏移會被抑制。At this time, the
另一方面,如圖2所示,一對鍊條部件12A、12B彼此嚙合的成為嚙合狀態的嚙合鍊條12隨著往後退方向Z2移動使一對鍊條部件12A、12B彼此解除相互嚙合而往分歧方向X分歧。結果使嚙合鍊條12(鍊條部件12A、12B)的大部分收容在收容部13内。On the other hand, as shown in FIG. 2, the pair of
其中,一對鍊條部件12A、12B中,互相嚙合之位在前後方向Y的外側的第1鏈結板22及第2鏈結板30與互相嚙合之位在前後方向Y的内側的第1鏈結板22及第2鏈結板30之間,在進退方向Z的位置有所偏移,其程度僅為在進退方向Z排列的連接銷23的1個節距。Among the pair of
此外,如圖1及圖2所示,嚙合鍊條12在長邊方向的前進方向Z1側的端部與可動體15連接。可動體15安裝有各種機能構件(例如升降台或起重機等)。隨著嚙合鍊條12的進退使可動體15往進退方向Z移動時,安裝在可動體15的機能構件也會和可動體15一起往進退方向Z移動。In addition, as shown in FIGS. 1 and 2, the end portion of the meshing
接著,針對可動體移動裝置11中,隨著一對鍊條部件12A、12B往前進方向Z1移動使該等相互嚙合而一體化,從而嚙合鍊條12成為直棒狀的嚙合狀態時的作用進行說明。Next, the operation of the movable
在使一對鍊條部件12A、12B嚙合從而使嚙合鍊條12成為嚙合狀態時,首先將鏈輪16於圖2的時鐘方向進行旋轉驅動。然後,一對鍊條部件12A、12B藉由誘導溝18分別引導連接銷23而往前進方向Z1移動。When the pair of
以此方式,一對鍊條部件12A、12B中,互相對應的第1鏈結板22的第1嚙合面25與第2鏈結板30的第2嚙合面32依序嚙合,並且第1鏈結板22的第1卡合面27與第2鏈結板30的第2卡合面34依序卡合,如圖1所示,嚙合鍊條12成為嚙合狀態。In this way, in the pair of
此時,如圖6所示,第1鏈結板22的第1卡合面27及第2鏈結板30的第2卡合面34是由能夠互相嵌合的凹凸面之波形的曲面所構成。因此,當第1卡合面27與第2卡合面34卡合時,藉由第1卡合面27與第2卡合面34凹凸嵌合,在第1卡合面27及第2卡合面34的延伸方向的第1鏈結板22與第2鏈結板30之間的位置偏移會被抑制。At this time, as shown in FIG. 6, the
此外,如圖6所示,當第1卡合面27與第2卡合面34卡合時,形成在第1卡合面27的卡合凹部28與形成在第2卡合面34的卡合凸部35會嵌合(遊動嵌合)。除此之外,如圖6及圖7所示,當第1鏈結板22的第1嚙合面25與第2鏈結板30的第2嚙合面32嚙合時,形成在第2嚙合面32的嚙合凹部33與形成在第1嚙合面25的嚙合凸部26會嵌合(遊動嵌合)。因此,藉由該等卡合凹部28與卡合凸部35的嵌合、及嚙合凹部33與嚙合凸部26的嵌合,在前後方向Y(連接銷23的延伸方向)的第1鏈結板22與第2鏈結板30之間的位置偏移會被有效地抑制。In addition, as shown in FIG. 6, when the
因此,藉由第1卡合面27與第2卡合面34的嵌合、卡合凹部28與卡合凸部35的嵌合、及嚙合凹部33與嚙合凸部26的嵌合,得以提升嚙合鍊條12的挫曲負載,故即使在嚙合鍊條12成為直棒狀的嚙合狀態時對嚙合鍊條12在進退方向Z施加壓縮負重,嚙合鍊條12仍不容易挫曲。Therefore, it is improved by the fitting of the first engaging
根據以上詳述的實施方式,能夠發揮如下般的效果。According to the embodiment detailed above, the following effects can be exerted.
(1)嚙合鍊條12中,鍊條部件12A的第1鏈結板22的第1卡合面27設有卡合凹部28,卡合凹部28沿著第1卡合面27延伸。鍊條部件12B的第2鏈結板30的第2卡合面34設有卡合凸部35,卡合凸部35沿著第2卡合面34延伸,並在當第1卡合面27與第2卡合面34卡合時與卡合凹部28嵌合。根據該構成,在鍊條部件12A、12B彼此在第1鏈結板22的第1卡合面27及第2鏈結板30的第2卡合面34卡合的狀態下,卡合凸部35與卡合凹部28會嵌合。因此,由於能夠抑制與連接銷23的延伸方向一致的前後方向Y中第1鏈結板22與第2鏈結板30之間的位置偏移,故能夠提升在鍊條部件12A、12B彼此嚙合而一體化的狀態下的挫曲負載。(1) In the engaging
(2)嚙合鍊條12中,鍊條部件12A的第1鏈結板22的第1嚙合面25設有嚙合凸部26,嚙合凸部26沿著第1嚙合面25延伸。鍊條部件12B的第2鏈結板30的第2嚙合面32設有嚙合凹部33,嚙合凹部33沿著第2嚙合面32延伸,並在當第1嚙合面25與第2嚙合面32嚙合時與嚙合凸部26嵌合。根據該構成,在鍊條部件12A、12B彼此在第1鏈結板22的第1嚙合面25及第2鏈結板30的第2嚙合面32嚙合的狀態下,嚙合凸部26與嚙合凹部33會嵌合。因此,由於能夠抑制與連接銷23的延伸方向一致的前後方向Y中第1鏈結板22與第2鏈結板30之間的位置偏移,故能夠提升在鍊條部件12A、12B彼此嚙合而一體化的狀態下的挫曲負載。(2) In the meshing
(3)嚙合鍊條12中,在鍊條部件12A的第1鏈結板22的第1卡合面27及鍊條部件12B的第2鏈結板30的第2卡合面34設有凹凸面,該凹凸面抑制卡合有第1卡合面27及第2卡合面34的鏈結板22、30彼此在卡合面27、34的延伸方向的位置偏移。根據該構成,在鍊條部件12A、12B彼此嚙合而一體化的狀態下,設於鏈結板22、30的卡合面27、34的凹凸面彼此會嵌合。因此,由於能夠抑制在卡合面27、34卡合的鏈結板22、30彼此在卡合面27、34的延伸方向的位置偏移,故能夠實現在鍊條部件12A、12B彼此嚙合而一體化的狀態下的挫曲負載的提升。(3) In the meshing
(4)嚙合鍊條12中,設於卡合面27、34的凹凸面為波形的曲面。根據該構成,當鍊條部件12A、12B彼此嚙合而一體化時,能夠使設於各個鏈結板22、30的卡合面27、34的凹凸面彼此圓滑地嵌合。(4) In the meshing
