本發明係鑒於上述先前技術的問題,目的在於提供一種小型且不佔用地方的繩索牽引裝置。而且,另一目的在於能夠在無商用電源的設備的地方使用。 In view of the above-mentioned problems of the prior art, the present invention aims to provide a rope traction device that is small and does not occupy space. Moreover, another purpose is to be able to be used in places where there is no commercial power supply equipment.
根據本發明的實施形態,繩索牽引裝置具備:差動減速式的減速裝置,具有可裝卸自如地連結旋轉式電動工具的輸出軸之輸入軸以及與可裝卸自如地供繩索纏繞的滑輪結合之輸出軸,並使施加至輸入軸的旋 轉減速且傳遞至輸出軸;支持體,裝有減速裝置;入口部及出口部,設置於支持體,且形成纏繞於滑輪之繩索的入口與出口;以及限制器件,設置於減速裝置或支持體,限制繩索的入口側被拉出至外側。 According to an embodiment of the present invention, a rope traction device is provided with: a differential reduction type reduction gear having an input shaft that is detachably connected to the output shaft of a rotary electric tool, and an output that is combined with a pulley that is detachably wound around the rope Shaft and make the rotation applied to the input shaft It is decelerated and transmitted to the output shaft; the support body is equipped with a deceleration device; the entrance part and the outlet part are arranged on the support body and form the entrance and exit of the rope wound around the pulley; and the restricting device is arranged on the deceleration device or the support body , The entrance side of the restriction rope is pulled out to the outside.
根據本發明的一實施形態,因能夠將旋轉式電動工具作為驅動源來牽引繩索,故裝置中無須裝入驅動源,且因纏繞於滑輪來進行牽引,故不需要捲取筒,從而使裝置整體小型。而且,作為旋轉式電動工具,能夠使用作業用的可攜帶的普通工具,從而無須耗費準備特殊驅動源的時間。若旋轉式電動工具是充電式,則不會有引繞電源線的麻煩,且在高層建築屋頂等難以取得商用電源的地方亦能夠使用。而且,藉由使用小型且減速比大的差動減速式的減速裝置,當在解除了限制器件的狀態下一邊使滑輪反轉一邊將繩索從入口側拉出至外側時,能夠進行緩行動作。 According to one embodiment of the present invention, since the rotary power tool can be used as the driving source to pull the rope, there is no need to install a driving source in the device, and because it is wound around the pulley for traction, the winding drum is not required, so that the device Overall small. Moreover, as a rotary electric tool, it is possible to use ordinary tools that can be carried for work, so there is no need to spend time preparing a special drive source. If the rotary power tool is a rechargeable type, there will be no trouble of winding the power cord, and it can also be used on the roof of a high-rise building where it is difficult to obtain commercial power. In addition, by using a small-sized differential reduction gear with a large reduction ratio, when the rope is pulled out from the entrance side to the outside while the pulley is reversed in a state where the restriction device is released, a slow motion can be performed.
而且,根據本發明的一實施形態,因與滑輪隔開間隔地設置入口部及出口部,並且於入口部及出口部與滑輪之間設置有將入口側繩索與出口側繩索分離的分離部,故能夠防止滑輪正轉時出口側繩索被捲入滑輪的入口側以及滑輪反轉時入口側繩索被捲入滑輪的出口側。 Furthermore, according to an embodiment of the present invention, since the inlet and outlet are provided at intervals from the pulley, and a separation portion is provided between the inlet and outlet and the pulley to separate the inlet-side rope from the outlet-side rope, Therefore, it is possible to prevent the outlet-side rope from being entangled in the inlet side of the pulley when the pulley is rotated forward, and the inlet-side rope being entangled in the outlet side of the pulley when the pulley is reversed.
而且,根據本發明的一實施形態,因入口部及出口部包含有隔開間隔而對向配置的入口部及出口部,形成為能夠通過入口部與出口部之間的間隙使繩索在外部與入口部之間進出以及使繩索在外部與出口部之間進出,故繩索對滑輪的裝載、卸除變得容易,並且因於滑輪蓋設置有阻礙部,上述阻礙部係於鎖定為關閉狀態時進入入口部與出口部之間的間隙以阻礙繩索從入口部或出口部脫落,故能夠防止使用中繩索從入口部或出口部脫落而意外地打開滑輪蓋。 Furthermore, according to an embodiment of the present invention, since the inlet portion and the outlet portion include the inlet portion and the outlet portion that are opposed to each other with an interval, they are formed so that the rope can be connected to the outside through the gap between the inlet portion and the outlet portion. The entry and exit between the entrance part and the entry and exit of the rope between the outside and the exit part facilitate the loading and unloading of the rope to the pulley, and because the pulley cover is provided with an obstruction part, the obstruction part is locked when it is closed. Entering the gap between the inlet and the outlet prevents the rope from falling off from the inlet or the outlet, so it can prevent the rope from falling off the inlet or the outlet during use and accidentally open the pulley cover.
而且,根據本發明的一實施形態,因支持體中具備供繩索纏繞而固定的卡住部(retainer),故於張力施加至繩索的入口側的狀態下解除限制器件對繩索從入口部朝外側的移動的限制,當想要使繩索從入口部朝外側移動時,預先將出口側的繩索纏繞並卡住於卡住部,藉此能夠在解除限制器件時防止繩索突然向反方向移動。而且,藉由一邊與卡住部滑動接觸一邊移動,亦能夠使摩擦制動發揮作用。 Furthermore, according to an embodiment of the present invention, since the support is provided with a retainer for the rope to be wound and fixed, the restriction device is released from the entrance to the outer side of the rope when tension is applied to the entrance side of the rope. When you want to move the rope from the entrance part to the outside, the rope on the exit side is wound and caught in the catch part in advance to prevent the rope from suddenly moving in the opposite direction when the restriction device is released. Moreover, by moving while slidingly contacting the catching portion, friction braking can also be exerted.
而且,根據本發明的一實施形態,當想要解除限制器件對繩索從入口部朝外側的移動的限制時,一邊使用手動旋轉具手動地使減速裝置的輸入軸正轉並使滑輪緩慢地正轉,一邊藉由操作部進行解除操作,由此能夠容易地解除。 Furthermore, according to an embodiment of the present invention, when it is desired to release the restriction on the movement of the rope from the entrance portion to the outside by the restriction device, the input shaft of the deceleration device is manually rotated forward and the pulley is slowly forwarded using a manual rotating tool. It can be easily released by performing the release operation with the operation part while turning.

The reference numeral 15 in FIG. 13 is used as a rechargeable electric drive of a rotary electric tool for electrically rotating and driving the
接下來,對上述實施例的使用方法進行說明。 Next, the method of using the above-mentioned embodiment will be described.
例如,如圖15所示,於想要將用以從屋頂卸貨的貨籃100吊起至建築物101的屋頂的情形下,屋頂側的作業人員要將垂吊具103設置於護牆102,並將兩個繩索固定具105、106設置於與護牆102為相反側的護牆104。而且,準備滑輪蓋50關閉且操作柄71固定於第一位置P1的繩索牽引裝置1、垂吊繩索(此處為纖維繩索)110,將繩索牽引裝置1的鎖定構件53向圖2的下方(圖9中之(1)箭頭B方向)下壓,卡合爪58遠離卡合槽38、39以解開鎖定,將滑輪蓋50向圖3的箭頭C方向打開。
For example, as shown in FIG. 15, in a situation where a
將垂吊繩索110的一端側從繩索牽引裝置1的入口部32與出口部33之間的間隙44***至入口通路部34,並通過分離部40的左側而在滑輪20上纏繞不到一圈,且通過分離部40的右側而從入口部32與出口部33的間隙44***至出口通路部35後(參照圖16),纏繞並卡住於卡住部80、81。然後,一邊將鎖定構件53向圖2的下方(圖9中之(1)的箭頭B方向)下壓一邊關閉滑輪蓋50(參照圖3的箭頭D),從而將嵌合部52嵌合於被嵌合部36、37。當釋放鎖定構件53的下壓時,藉由壓縮彈簧54、55將鎖定構件53向圖2的上方(圖9中之(1)的箭頭A方向)施力,卡合爪58卡合於卡合槽38、39內而鎖定。
One end of the hanging
於繩索牽引裝置1的繩索安裝孔4與繩索固定具105、106之間張緊設置有兩根繩索(可以是纖維繩索、纜繩索(wire rope)中之任一個)111、112,以確保支點。繩索111、112對繩索安裝孔4的安裝係藉由例如將繩索端部的掛鉤勾掛在已裝設於繩索安裝部4的鉤環(carabiner)來進行。然後,將垂吊繩索110的另一端側纏繞於垂吊具102的中繼皮帶輪113、前端皮帶輪114並垂下至地面。地面側的作業人員使貨籃100吊持於垂吊繩索110的下端。假如即使地面方向的力施加至垂吊繩索110而滑輪20試圖向反轉方向旋轉,繩索牽引裝置1的棘輪機構60的棘爪64的前端部亦卡合於棘輪齒輪62以限制輸入軸7的旋轉,因此滑輪20不旋轉,阻止了垂吊繩索110
的入口側被拉出至外部。
Two ropes (either fiber rope or wire rope) 111 and 112 are tensioned between the
於屋頂處,將已裝載於繩索牽引裝置1的垂吊繩索110的出口側繩索110a從卡住部80、81取下,操作柄71保持固定於第一位置P1。如圖13中之(1)所示,將具有鍵槽17的圓柱狀的柄18安裝到充電式電動驅動器15的夾具16,一邊使鍵19嵌合於繩索牽引裝置1的輸入軸7的鍵槽14、17,一邊將柄18***至軸孔13而連結,從而向正轉方向驅動充電式電動驅動器15。
At the roof, the outlet side rope 110a of the hanging
繩索牽引裝置1中,因棘輪機構60容許輸入軸7的正轉,故輸入軸7正轉,利用減速裝置本體6減速並傳遞至輸出軸8,與輸出軸8結合的滑輪20向圖16的逆時針方向旋轉。由此,垂吊繩索110的入口側通過入口通路部34與分離部40的左側而被拉入滑輪20的左上部,纏繞不到一圈並從滑輪20的右上部通過分離部40的右側與出口通路部35而來到外部。結果,貨籃100從地面上升。
In the
到達屋頂後,停止充電式電動驅動器15對繩索牽引裝置1的驅動。然後,垂吊繩索110的入口側繩索110b因貨籃100的荷重而被朝向護牆102方向拉拽,但因棘輪機構60限制輸入軸7的反轉以約束滑輪20的反轉,故阻止了垂吊繩索110從繩索牽引裝置1的入口側被朝向外側方向拉出。因此,貨籃100成為停止於護牆102的外側的狀態。
After reaching the roof, the driving of the
於將未圖示的貨物堆載於貨籃100後想要向地面下降的情形下,首先,將垂吊繩索110的出口側繩索110a纏繞於卡住部80、81,並固定成不會拉回到滑輪側。
In the case where unshown goods are stacked on the
接下來,為了解除繩索牽引裝置1的棘輪機構60的旋轉限制,要將操作柄71轉動到第二位置P2,使卡合突起74卡合於卡合凹部76並固定,但因被強力向護牆102的方向拉拽的入口側繩索110b對滑輪20向順時針方向施
力,故棘輪齒輪62強有力地按壓棘爪64的前端部,因此棘爪64變得難以旋動。
Next, in order to release the rotation restriction of the
因此,如圖14中之(1)所示,一邊將手動式旋轉工具90的突起91嵌合於輸入軸7的鍵槽14,一邊將旋轉軸部92***至軸孔13中。然後,一邊將把手部93向圖14中之(1)之逆時針方向(正轉方向)轉動以放鬆棘輪齒輪62對棘爪64的按壓,一邊將操作柄71轉動至第二位置P2,使卡合突起74卡合於卡合凹部76並固定。由此,棘爪64遠離棘輪齒輪62,解除了輸入軸7的旋轉限制。
Therefore, as shown in (1) of FIG. 14, while fitting the
該狀態下,用手抓住出口側繩索110a並從繩索牽引裝置1的卡住部80、81取下後,若出口側繩索110a的握持力減弱,則滑輪20利用入口側繩索110b的拉拽力而向圖16的順時針方向旋轉,且出口側繩索110a被拉回到入口側。此時,因減速裝置本體6的差動減速機構成為大的負載,故垂吊繩索110從入口部32緩慢地朝向外部拉出。
In this state, after grabbing the outlet-side rope 110a by hand and removing it from the catching
藉此,貨籃100緩慢下降。若將垂吊繩索110的出口側繩索110a壓接至卡住部80、81,則能夠施加摩擦制動而更緩慢地下降。當想要中斷下降時,將出口側繩索110a纏繞於卡住部80、81即可;當想要使貨籃100安全地停止時,將操作柄71移動至第一位置P1即可。
As a result, the
與上述情況不同地,如圖17所示,當作業人員A藉由繩索進入技術進行建築物101的外壁的修補時,於想要在作業人員A的下側升降自如地配備鋁製且上表面開口之箱型的垂吊式養護裝置120的情形下,使上端分別固定在已裝設於建築物101的護牆102的兩個垂吊具130、131之垂吊繩索(此處為纖維繩索)132、133垂下於地面,且於地面附近將垂吊繩索132、133裝載於兩個繩索牽引裝置1-1、1-2,經由兩根繩索(可以是纖維繩索、纜繩索中之任一個)134、135將垂吊式養護裝置120的左側吊持於一個繩索牽
引裝置1-1的繩索安裝孔4,並經由兩根繩索136、137將垂吊式養護裝置120的右側吊持於另一個繩索牽引裝置1-2的繩索安裝孔4。
Unlike the above situation, as shown in Fig. 17, when the worker A uses rope entry technology to repair the outer wall of the building 101, he wants to equip the lower side of the worker A with aluminum and upper surface In the case of an open box-type hanging type maintenance device 120, the upper ends of the hanging ropes (here, the fiber ropes) of the two hanging
將繩索固定具138、139裝設於建築物101的屋頂的護牆104,將作業人員A用的主側與支承側的安全繩索140、141的一端側固定,並將另一端側越過護牆102而垂落於地面附近。將作業人員A自身穿著的安全帶的主側的短索(lanyard)勾掛在已安裝於安全繩索140之升降器具(未圖示),將支承側的短索勾掛在已安裝於安全繩索141的防墜落器具(未圖示),越過護牆102而沿著建築物101的外表面垂吊於安全繩索140,並下降至垂吊式養護裝置120的正上方。
Install the rope fixtures 138, 139 on the
作業人員A以體重完全不施加或幾乎不施加至垂吊式養護裝置120的方式,且以安全繩索140與安全繩索141的下側懸掛於垂吊式養護裝置120中的方式,進行對建築物101的外表面的檢查、修補等作業。作業中產生的修補構件以及牆壁等的碎片等掉落至垂吊式養護裝置120中並防止向外部飛散。
The worker A performs the construction on the hanging type maintenance device 120 with no weight or almost no weight applied to the hanging type maintenance device 120, and the
在想要相對於建築物101移動到比當前作業時高一層的作業範圍的情形下,作業人員A將安裝於安全繩索140、141的升降器具、防墜落器具的位置稍微向上方移動並進行登高。然後,藉由所攜帶的電動驅動器150將操作柄71位於第一位置P1的繩索牽引裝置1-1的輸入軸7向正轉方向旋轉驅動,使垂吊式養護裝置120的左側沿著垂吊繩索132稍微上升;同樣地,藉由所攜帶的電動驅動器150將操作柄71位於第一位置P1的繩索牽引裝置1-2的輸入軸7向正轉方向旋轉驅動,使垂吊式養護裝置120的右側沿著垂吊繩索133稍微上升,從而移動至高一層的作業範圍。
In a situation where he wants to move to a working area one level higher than the current work in the building 101, the worker A moves the lifting equipment and the fall prevention equipment installed on the
在移動前後或移動期間,作業員A的體重完全不施加或幾乎不施加至垂吊式養護裝置120。當上升高度不足時,將作業人員A的登高與 垂吊式養護裝置120的上升重複進行幾次。然後,在建築物101的外表面的比上一次作業的稍高側進行修補等作業。 Before and after the movement or during the movement, the weight of the operator A is not applied at all or hardly applied to the hanging type maintenance device 120. When the ascent height is insufficient, the ascent of operator A is The ascent of the hanging type curing device 120 is repeated several times. Then, work such as repair is performed on the outer surface of the building 101 slightly higher than the previous work.
以下,同樣地,重複進行對建築物101的外表面之修補等作業以及作業人員A的登高及垂吊式養護裝置120的上升,並從地面側到屋頂進行對建築物101的外表面之修補等作業。 Hereinafter, in the same way, the work of repairing the outer surface of the building 101, the ascent of the worker A and the lifting of the hanging type maintenance device 120 are repeated, and the repair of the outer surface of the building 101 is performed from the ground side to the roof. Wait for homework.
假如想要在中途將作業位置變更到建築物101的稍下方,則作業人員A藉由將安裝於安全繩索140、141的升降器具、防墜落器具的位置稍向下方移動,便下降至所期望的高度位置。
If you want to change the working position to slightly below the building 101 in the middle, the operator A moves the lifting equipment and the fall prevention equipment installed on the
然後,將繩索牽引裝置1-1的出口側繩索132a纏繞並卡住於卡住部80、81,使用手動式旋轉工具90,一邊使繩索牽引裝置1-1的輸入軸7正轉一邊將操作柄71改變到第二位置P2。隨後,用手抓住出口側繩索132a並從卡住部80、81取下後,若出口側繩索132a之握持力減弱,則滑輪20利用入口側繩索132b的拉拽力向圖16的順時針方向旋轉,且出口側繩索132a被拉回至入口側而垂吊式養護裝置120的左側下降。當下降至所期望的高度時,將出口側繩索132a卡住於卡住部80、81,將操作柄71改變至第一位置P1。對繩索牽引裝置1-2亦進行相同的操作,使垂吊式養護裝置120的右側下降至所期望的高度。當下降高度不足時,將作業人員A的下降與垂吊式養護裝置120的下降重複進行幾次即可。
Then, the outlet side rope 132a of the rope traction device 1-1 is wound and caught in the catching
另外,若首先使垂吊式養護裝置120上升至屋頂附近,則亦能夠一邊重複進行對建築物101的外表面之修補等作業以及作業人員A的下降及垂吊式養護裝置120的下降,一邊從屋頂側開始進行對建築物101的外表面之修補等作業。而且,當由兩個作業人員進行對建築物外表面之修補作業時,亦可分開進行對繩索牽引裝置1-1、1-2的操作。 In addition, if the hanging type maintenance device 120 is raised to the vicinity of the roof first, it is also possible to repeat the work such as repairing the outer surface of the building 101, the lowering of the worker A and the lowering of the hanging type maintenance device 120. Repairing the outer surface of the building 101, etc., is performed from the roof side. In addition, when two workers perform repair work on the outer surface of the building, the rope pulling devices 1-1 and 1-2 can also be operated separately.
根據該實施例,因能夠將旋轉式電動工具作為驅動源來進行
垂吊繩索110(132、133)的牽引,故裝置中無須裝入驅動源,且因纏繞於滑輪20來進行牽引,故不需要捲取筒,從而使裝置整體小型。而且,作為旋轉式電動工具,能夠使用電動驅動器15等作業用的可攜帶的普通工具,從而無須耗費準備特殊驅動源的時間。若旋轉式電動工具是充電式,則不會有引繞電源線的麻煩,且在建築屋頂或建築物外側等難以取得商用電源的地方亦能夠使用。而且,藉由使用小型且減速比大的差動減速式的減速裝置本體6,當在解除了限制器件60的狀態下一邊使滑輪20反轉一邊將垂吊繩索110(132、133)從入口部32拉出至外側時,能夠進行緩行動作。

The suspension rope 110 (132, 133) is hauled, so there is no need to install a driving source in the device, and because it is wound around the
而且,因由隔開間隔對向配置的入口部32及出口部33構成繩索出入口部31,且形成為能夠通過入口部32與出口部33之間的間隙44使垂吊繩索110(132、133)在外部與入口部32之間進出以及使垂吊繩索110在外部與出口部33之間進出,故垂吊繩索110(132、133)對滑輪20的裝載、卸除變得容易。
In addition, since the
而且,因與滑輪20隔開間隔地設置繩索出入口部31,並且於繩索出入口部31與滑輪20之間設置有將入口側繩索110b(132b、133b)與出口側繩索110a(132a、133a)分離的分離部40,故能夠防止滑輪20正轉時出口側繩索110a(132a、133a)被捲入滑輪20的入口側以及滑輪20反轉時入口側繩索110b(132b、133b)被捲入滑輪20之出口側。
Furthermore, because the rope entrance and
而且,因支持體2中具備供垂吊繩索110(132、133)纏繞而卡住的卡住部80、81,故於張力施加至垂吊繩索110(132、133)的入口側的狀態下解除限制器件10的限制,但當想要使垂吊繩索110(132、133)從入口部32朝外側移動時,預先將出口側繩索110a(132a、133a)纏繞並卡住於卡住部80、81,藉此能夠在解除限制器件10時防止垂吊繩索110(132、133)突然向反方向移
動。而且,藉由一邊與卡住部80、81滑動接觸一邊移動,亦能夠使摩擦制動發揮作用。
Furthermore, since the
而且,當想要解除限制器件10對繩索從入口部32朝外側的移動的限制時,一邊使用手動式旋轉工具90手動地使減速裝置本體6的輸入軸7正轉並使滑輪20緩慢地正轉,一邊藉由操作柄71進行解除操作,由此能夠容易地解除。
Moreover, when it is desired to release the restriction of the
另外,上述實施例中,列舉作為電動工具的充電式電動驅動器為例,但本發明不受該例任何限定,也可以是電動鑽頭等其他旋轉式電動工具。而且,亦可使用非充電式的電動工具。 In addition, in the above-mentioned embodiments, a rechargeable electric drive as an electric tool is taken as an example, but the present invention is not limited to this example at all, and other rotary electric tools such as electric drills may also be used. Moreover, non-rechargeable electric tools can also be used.
而且,上述實施例中,雖然於垂吊繩索之裝載後在入口部與出口部之間留出間隙,但亦可如圖18、圖19之繩索牽引裝置1A所示,將滑輪蓋50A之嵌合部向上方延伸設置,而能夠嵌合至入口部32A與出口部33A之上端,且於滑輪蓋50A之上方延長部之背面側設置阻礙部140,該阻礙部140堵住入口部32A與出口部33A之間的間隙44A,阻礙已***至入口部32A的入口通路部34的入口側繩索向間隙44A偏離以及阻礙已***至出口部33A的出口通路部35的出口側繩索向間隙44A偏離。藉由阻礙部140,於繩索牽引裝置之使用中,能夠防止垂吊繩索向入口部32A與出口部33A的間隙44A偏離並碰撞至滑輪蓋50A的上端部背面而使該滑輪蓋意外地打開。

而且,上述實施例中,雖然列舉在差動減速裝置本體之輸入軸側設置限制所裝載的繩索被從入口側拉回的限制器件的情形為例進行了說明,但亦可設置於輸出軸側。 Moreover, in the above-mentioned embodiment, although the case where a restraining device is provided on the input shaft side of the differential reduction gear main body to restrain the loaded rope from being pulled back from the inlet side has been described as an example, it may be provided on the output shaft side. .
而且,使已於上端側處確保支點的垂吊繩索上下垂下,將該垂吊繩索的下端側裝載於繩索牽引裝置,利用繩索來連結作業人員所穿著的線束的D環與繩索牽引裝置的繩索安裝孔,藉此能夠利用所攜帶的充電式電動驅動器等進行驅動而上升。 In addition, the hanging rope with the fulcrum at the upper end side is suspended down, the lower end of the hanging rope is loaded on the rope pulling device, and the rope is used to connect the D ring of the harness worn by the operator and the rope of the rope pulling device The mounting hole can thereby be driven and raised by a portable electric drive or the like.
繼而,限制器件亦可構成為取代棘輪機構而包含有:凸輪(comb),構成為當繩索欲朝向從入口部被拉出至外側的方向移動時咬入繩索以限制移動,當欲向相反方向移動時遠離繩索以容許移動;施力器件,將凸輪向咬入繩索的方向施力;以及解除器件,使凸輪遠離繩索以解除限制。 Then, the restricting device may be configured to replace the ratchet mechanism and include: a cam (comb) configured to bite into the rope to restrict movement when the rope is going to be pulled out from the entrance to the outside, and when it is going to the opposite direction When moving, move away from the rope to allow movement; apply a force device to force the cam in the direction of the rope; and release the device to move the cam away from the rope to release the restriction.
將凸輪式的限制器件的具體例之一表示於圖20。圖20的繩索牽引裝置1B中支持體2B的上部向上方延伸設置,於正面側裝有凸輪式的限制器件200。限制器件200中,元件符號201是裝設於支持體2B的上端部的正面側之支持板,左側部是呈U字狀彎折且於內側形成有作為繩索抵接部的繩索插通部202之彎折部203,右側部是呈U字狀彎折且旋轉自如地裝有旋動軸204之彎折部205。繩索插通部202沿著裝載於繩索牽引裝置1B之繩索的入口側的路徑而配備,且相對於入口部32的入口通路部34呈直線配置。凸輪208的基端部嵌著於旋動軸204,該凸輪208係於外周部206突出設置有許多齒207而成。凸輪208以旋動軸204為旋動中心而能夠相對於插通至繩索插通部202的繩索向接近的方向(參照圖20的箭頭I)與遠離的方向(參照圖20的箭頭J)旋動。於旋動軸204與凸輪208之間夾設有對凸輪208一直向圖20的順時針方向施力的扁平螺旋彈簧(未圖示)。
One specific example of the cam type restricting device is shown in FIG. 20. In the rope pulling device 1B of FIG. 20, the upper part of the support body 2B is extended upward, and the cam
於凸輪208之正中附近旋轉自如地裝有旋動軸209,L字狀的解除操作構件210的基端部嵌著於該旋動軸209。向支持體2B的前方突出之圓柱狀的操作突起211裝設於解除操作構件210的角部,藉由用手指操作操
作突起211而以旋動軸209為中心使解除操作構件210旋動自如(參照圖20的箭頭K、L)。解除操作構件210的前端側是卡合部212,呈J字狀彎折且扣卸自如地卡合於支持板201的彎折部205的外側。旋動軸209與解除操作構件210之間夾設有對解除操作構件210一直向圖20的逆時針方向施力的扁平螺旋彈簧(未圖示)。
A
對圖20的繩索向繩索牽引裝置1B裝載的方法進行說明,首先,用手指操作限制器件200的操作突起211,平行地進行凸輪208的旋動與解除操作構件210的旋動,如圖21所示將卡合部212卡合於彎折部205的外側。打開滑輪蓋50將垂吊繩索110的一端側插通至限制器件200的繩索插通部202,進而從入口部32與出口部33之間的間隙44***至入口通路部34,通過分離部40的左側而在滑輪20上纏繞不到一圈,通過分離部40的右側從入口部32與出口部33的間隙44***至出口通路部35後(參照圖21),纏繞並卡住於卡住部80、81。
The method of loading the rope to the rope traction device 1B of FIG. 20 will be described. First, the operation protrusion 211 of the
然後,關閉滑輪蓋50,並且用手指操作解除操作構件210的操作突起211,解開卡合部212的卡合,平行地進行凸輪208的旋動與解除操作構件210的旋動,使凸輪208接近垂吊繩索110並拿開手指。凸輪208藉由扁平螺旋彈簧向外周部206插通至繩索插通部202的繩索方向上施力而壓接至垂吊繩索110。當於繩索插通部202的出口側處垂吊繩索110被朝向下方(參照圖22的箭頭R)拉拽時,對凸輪208施加逆時針方向的外力,但因外周部206處於遠離垂吊繩索110的方向上,故凸輪208容易向逆時針方向旋動,容許入口側繩索110b向滑輪方向的移動。相反,當於繩索插通部202的入口側處垂吊繩索110被朝向上方(參照圖22的箭頭S)拉拽時,對凸輪208施加順時針方向的外力,但因外周部206處於接近垂吊繩索110的方向上,從而凸輪208咬入垂吊繩索110而限制移動(垂吊繩索110由繩索插通部202與凸輪
208夾持)。
Then, the
在開始垂吊繩索110的牽引的情形下,從卡住部80、81取下出口側繩索110a,當藉由充電式電動驅動器15使輸入軸7正轉時,滑輪20正轉,此時因限制器件200處於容許移動的方向上,故垂吊繩索110被順利牽引。
When the traction of the hanging
在想要停止垂吊繩索110的牽引的情形下,停止充電式電動驅動器15對輸入軸7的驅動。當於繩索插通部202的入口側處將垂吊繩索110朝向上方拉拽時,對凸輪208施加順時針方向的外力,但因外周部206處於接近垂吊繩索110的方向上,故凸輪208咬入垂吊繩索110以限制移動。因此,入口側繩索110b不會被拉回。
When it is desired to stop the traction of the hanging
當在入口側繩索110b被朝向圖22的上方拉拽的狀態下,想要向被拉拽的方向拉回時,將出口側繩索110a纏繞並卡住於卡住部80、81,使手動式旋轉工具90與輸入軸7結合並正轉,放鬆凸輪208對垂吊繩索110的咬入,用手指操作限制器件200的操作突起211,平行地進行凸輪208的旋動與解除操作構件210的旋動,如圖21所示使卡合部212卡合於彎折部205的外側。然後,當握持從卡住部80、81取下的出口側繩索110a的握持力減弱時,滑輪20利用入口側繩索110b的拉拽力而反轉,出口側繩索110a被拉回至入口側。
When the entrance side rope 110b is pulled upward in FIG. 22 and you want to pull it back in the pulled direction, the exit side rope 110a is wound and caught in the catching
根據圖20的變形例,不使用棘輪機構便能夠限制於垂吊繩索110的牽引中或停止中入口側繩索110b被拉回,且於想要使垂吊繩索110回到原來位置的情形下能夠解除限制。而且,在支持體2B中比入口部32靠入口側處配設有限制器件200的繩索插通部202,因此入口側處的繩索通路變長,能夠更順利地進行垂吊繩索110向滑輪20的導引。
According to the modification of FIG. 20, it is possible to restrict the entrance side rope 110b from being pulled back during traction or stopping of the hanging
將凸輪式的限制器件的另一具體例表示於圖23、圖24中。於圖23、圖24之繩索牽引裝置1C中支持體2C之正面側右上部,在出口部33、
滑輪20及卡住部80之間裝有凸輪式的限制器件300。限制器件300中,元件符號301是裝設於支持體2C的正面側的右上部之支持板,右側部是呈U字狀彎折且內側旋轉自如地裝有旋動軸304的彎折部305。於外周部306突出設置有許多齒307而成之凸輪308的基端部嵌著於旋動軸304。凸輪308能夠以旋動軸304為旋動中心而相對於通過後述繩索抵接部的繩索槽的繩索向接近的方向以及遠離的方向旋動(參照圖24的箭頭M、N)。於旋動軸304與凸輪308之間夾設有對凸輪308一直向圖23、圖24的逆時針方向施力的扁平螺旋彈簧(未圖示)。
Another specific example of the cam type restricting device is shown in FIGS. 23 and 24. In the rope pulling device 1C of FIGS. 23 and 24, the upper right part of the front side of the support body 2C is in the
於凸輪308的正中附近旋轉自如地裝有旋動軸309,L字狀的解除操作構件310的基端部嵌著於該旋動軸309。於解除操作構件310的角部裝設有向支持體2C的前方突出之圓柱狀的操作突起311,藉由用手指操作操作突起311而以旋動軸309為中心使解除操作構件310旋動自如(參照圖24的箭頭O、Q)。解除操作構件310的前端側是卡合部312,呈J字狀彎折且扣卸自如地卡合於支持板301的彎折部305的外側。於旋動軸309與解除操作構件310之間夾設有對解除操作構件310一直向圖23、圖24的順時針方向施力的扁平螺旋彈簧(未圖示)。
A
分離部40C係圖23、圖24的右側向斜下方向呈鷹鼻狀延伸設置並成為寬鬆地***至滑輪20的H字槽21中的繩索抵接部45,於繩索抵接部45的外側面側形成有剖面呈圓弧狀的繩索槽46。滑輪蓋50C係於圖23的右上部分之側面形成有開口400,使得即使凸輪308與解除操作構件310旋動亦不與滑輪蓋50C發生干擾。
The separating
對將繩索裝載至如圖23、圖24般構成的繩索牽引裝置1C的方法進行說明,首先,用手指操作限制器件300的操作突起311,平行地進行凸輪308的旋動與解除操作構件310的旋動,且如圖25所示將卡合部312卡合
於彎折部305的外側。打開滑輪蓋50C將垂吊繩索110的一端側從入口部32與出口部33之間的間隙44***至入口通路部34,並通過分離部40C的左側在滑輪20上纏繞不到一圈,嵌入分離部40C的繩索導引部45的繩索槽46中,並從入口部32與出口部33的間隙44***至出口通路部35後(參照圖25),纏繞並卡住於卡住部80、81。
The method of loading the rope to the rope pulling device 1C configured as shown in FIGS. 23 and 24 will be described. First, the operation protrusion 311 of the
然後,關閉滑輪蓋50C,並且用手指操作解除操作構件310的操作突起311,解開卡合部312的卡合,平行地進行凸輪308的旋動與解除操作構件310的旋動,使凸輪308接近垂吊繩索110並拿開手指。凸輪308藉由扁平螺旋彈簧使外周部306向繩索方向旋動施力從而將垂吊繩索110壓接至繩索抵接部45(參照圖26)。當對垂吊繩索110施加從滑輪20的繩索出口附近(繩索槽46的入口附近)朝向出口部33的方向(參照圖26的箭頭T)的力時,對凸輪308施加順時針方向的外力,但因外周部306處於遠離已嵌入繩索槽46的垂吊繩索110的方向上,故凸輪308容易向順時針方向旋動,容許從出口側繩索110a之出口部33朝向外側方向的移動。相反,當對垂吊繩索110施加從入口部32向圖26的上方拉拽的方向(參照圖26的箭頭U)的力時,對凸輪308施加逆時針方向的外力,但因外周部306處於接近已嵌入繩索槽46的垂吊繩索110的方向上,故凸輪308係外周部306咬入垂吊繩索110以限制移動(垂吊繩索110夾持於凸輪308與繩索抵接部45之間)。
Then, the pulley cover 50C is closed, and the operating protrusion 311 of the operating
在開始垂吊繩索110的牽引的情形下,從卡住部80、81取下出口側繩索110a,當藉由充電式電動驅動器15使輸入軸7正轉時,滑輪20正轉,此時因限制器件300處於容許垂吊繩索110的移動的方向上,故垂吊繩索110被順利牽引。
When the traction of the hanging
在想要停止垂吊繩索110的牽引的情形下,停止充電式電動驅動器15對輸入軸7的驅動。當將入口側繩索110b向入口部32的上方拉拽時,嵌入繩
索抵接部45的繩索槽46的出口側繩索110a被朝向滑輪20的方向拉拽而對凸輪308施加逆時針方向的外力,但因外周部307處於接近垂吊繩索110的方向上,故凸輪308咬入垂吊繩索110以限制移動。因此,垂吊繩索110不會被拉回。
When it is desired to stop the traction of the hanging
當在入口側繩索110b被朝向圖26的上方拉拽的狀態下想要向被拉拽的方向返回時,將出口側繩索110a纏繞並卡住於卡住部80、81,使手動式旋轉工具90與輸入軸7結合並正轉,放鬆凸輪308對垂吊繩索110的咬入,用手指操作限制器件300的操作突起311,平行地進行凸輪308的旋動與解除操作構件310的旋動,如圖25所示使卡合部312卡合於彎折部305的外側。然後,當握持從卡住部80、81取下的出口側繩索110a的握持力減弱時,滑輪20利用入口側繩索110b的拉拽力而反轉,出口側繩索110a被拉回至入口側。
When the entrance side rope 110b is pulled upward in FIG. 26 and wants to return to the pulled direction, the exit side rope 110a is wound and caught in the catching
根據圖23、圖24的變形例,不使用棘輪機構便能夠限制於垂吊繩索110之牽引中或停止中入口側繩索110b被拉回,且於想要使垂吊繩索110回到原來位置的情形下能夠解除限制。而且,在支持體2C中的出口部33、滑輪20、卡住部80之間裝備限制器件300,故裝置不必很大。而且,因藉由繩索抵接部45與凸輪308夾持垂吊繩索110,故能夠確實地限制垂吊繩索110向被拉回的方向的移動。
According to the modification of FIGS. 23 and 24, without using a ratchet mechanism, it is possible to restrict the
另外,亦可將限制器件300裝備於入口部32與滑輪20之間(該情形下,將分離部的圖23、圖24中之左側向斜下方向延伸設置來作為繩索抵接部即可)。
