Description

簡易型防護管***器 Simple protective tube inserter

本發明係關於一種用以進行防護管之***或取下之不具備驅動裝置的簡易型防護管***器，該防護管係覆蓋架設於電線桿等上之電線。 The invention relates to a simple protective tube inserter without a driving device for inserting or removing a protective tube, the protective tube covering an electric wire erected on a telephone pole or the like.

為了保護架空電線免因樹木等之接觸而造成之損傷，使用有防護管。此外，於架空電線附近進行作業之情況下，為了防止作業者或作業機器碰觸電線，也利用防護管。 In order to protect overhead wires from damage caused by contact with trees, etc., protective tubes are used. In addition, when working near the overhead wire, in order to prevent the operator or the working machine from touching the wire, a protective tube is also used.

圖6為被連結之防護管101之立體圖。 FIG. 6 is a perspective view of the connected protective tube 101.

構成圖6所示之防護管101之本體部102、與形成於該本體部102之一端側之母型嵌合部103及形成於另一端側之公型嵌合部104，係使用具有彈性及可撓性之絕緣材料形成。其等如虛線所示具有可於內側收容架空電線100之內徑，並於本體部102之上方朝長邊方向呈一直線狀地形成有狹縫狀之開口部107。利用此種之材質及形狀，藉由將開口部107打開而將架空電線100收容於內側，且憑籍基於防護管101所具有之彈性而致之復原力使其閉合，藉此即可覆蓋架空電線100。自形成開口部107之對向之兩端緣部，分別形成有朝圓筒之擴徑側平行延長之一對翅片部109。 The body portion 102 constituting the protective tube 101 shown in FIG. 6 and the female fitting portion 103 formed on one end side of the body portion 102 and the male fitting portion 104 formed on the other end side are used to have elasticity and Flexible insulating material. As shown by the dotted line, they have an inner diameter capable of accommodating the overhead wire 100 inside, and a slit-shaped opening 107 is formed in a straight line above the body portion 102 in the longitudinal direction. Using this material and shape, the overhead wire 100 is housed inside by opening the opening 107, and closed by the restoring force based on the elasticity of the protective tube 101, thereby covering the overhead Wire 100. A pair of fin portions 109 extending parallel to the enlarged diameter side of the cylinder are formed from the opposite end edges of the opening 107.

此外，如圖6所示，於防護管101之長邊方向之一端形成有公型嵌合部104，且於另一端形成有母型嵌合部103，該母 型嵌合部103可與具有該公型嵌合部104之另一防護管101連接。其等連結之防護管101分別被設定為既定長度，且以彼此之母公型嵌合部103、104增加連接複數根，進而可覆蓋較長之架空電線100。 In addition, as shown in FIG. 6, a male fitting portion 104 is formed at one end of the protective tube 101 in the longitudinal direction, and a female fitting portion 103 is formed at the other end. The female fitting portion 103 may be The other protection tube 101 of the male fitting portion 104 is connected. The protective tubes 101 connected to each other are set to a predetermined length, and a plurality of female male fitting portions 103 and 104 are added to connect a plurality of pieces, so that the long overhead wire 100 can be covered.

其中，公型嵌合部104，係構成為外徑較本體部102大。並且，於母型嵌合部103形成有當嵌合時可收容公型嵌合部104且可使其於內部結合之收容部106。因此，母型嵌合部103之收容部106，係較公型嵌合部104之外徑更大。 Among them, the male fitting portion 104 is configured to have a larger outer diameter than the body portion 102. In addition, the female fitting portion 103 is formed with a receiving portion 106 that can receive the male fitting portion 104 and can be internally coupled when fitted. Therefore, the receiving portion 106 of the female fitting portion 103 is larger than the outer diameter of the male fitting portion 104.

通常，當將如上述之防護管101朝架空電線100上安裝時，首先，將第一根之防護管101***架空電線100之後，接著將第二根之防護管101之前端***架空電線100，且於被***架空電線100之狀態下，利用彼此之母公型嵌合部103、104連接其等之2根防護管101。然後，藉由重複地進行上述之動作，將複數根防護管101***架空電線100。 Generally, when installing the protective tube 101 as described above toward the overhead wire 100, first, after inserting the first protective tube 101 into the overhead wire 100, and then inserting the front end of the second protective tube 101 into the overhead wire 100, In the state where the overhead wire 100 is inserted, the two female protective tubes 101 are connected to each other by the male and female fitting portions 103 and 104 of each other. Then, by repeatedly performing the above operation, a plurality of protective tubes 101 are inserted into the overhead wire 100.

其次，對將如上述之防護管101***架空電線100之裝置進行說明。 Next, a device for inserting the protective tube 101 as described above into the overhead wire 100 will be described.

圖7為習知之管***器110之前視圖。該管***器110，係以藉由上端之電線抑制角鋼111與導件本體112夾持之方式被固定於架空電線100。沿自導件本體112延長之導引棒113而通過之防護管101，係通過導件本體112與驅動輪胎116之間。然後，繼續進行移位之防護管101，藉由擴管用板115而使開口部107(參照圖6)擴張而被朝架空電線100引導。 7 is a front view of the conventional tube inserter 110. The tube inserter 110 is fixed to the overhead wire 100 in such a manner that the upper wire restraining angle 111 and the guide body 112 are clamped. The protective tube 101 passing along the guide bar 113 extended from the guide body 112 passes between the guide body 112 and the driving tire 116. Then, the protective tube 101 that continues to be displaced is expanded toward the overhead wire 100 by expanding the opening 107 (see FIG. 6) by the tube expansion plate 115.

其中，為了降低與防護管101之摩擦，於導件本體112之側面及下端側設置有滾子127。藉此，可減小滑動接觸阻力，可不損失自驅動輪胎116施加之力而平滑地將防護管101***架空 電線100。專利文獻1記載有如上述之管***器110。 In order to reduce friction with the protective tube 101, rollers 127 are provided on the side and lower end sides of the guide body 112. Thereby, the sliding contact resistance can be reduced, and the protective tube 101 can be smoothly inserted into the overhead wire 100 without losing the force applied from the driving tire 116. Patent Document 1 describes the tube inserter 110 as described above.

專利文獻1：日本專利特開平8-182135號公報 Patent Document 1: Japanese Patent Laid-Open No. 8-182135

如上述之管***器110，需要驅動輪胎116及用以驅動該輪胎之裝置，這點會增加整體之重量。此外，除了管***器110整體之重量增大，而且還需要花費驅動系統之設置時間，因此作業效率不佳。因此，為了達到輕量化，省略包含驅動輪胎116之驅動系統之構成為最有效。 Like the tube inserter 110 described above, the tire 116 and the device for driving the tire are required, which increases the overall weight. In addition, in addition to the increased weight of the tube inserter 110 as a whole, it also takes time to set up the drive system, so the work efficiency is not good. Therefore, in order to achieve weight reduction, it is most effective to omit the configuration of the driving system including the driving tire 116.

另一方面，由於導引棒113相對於把持之架空電線100而傾斜，因此，當使防護管101沿導引棒113衝撞於架空電線100時，防護管101會自架空電線100側受到大的反作用力。因此，於省略驅動輪胎116之構成中，需要一面以不使防護管101自擴管用皮115脫落之方式朝架空電線100側按壓、一面進行作業。 On the other hand, since the guide bar 113 is inclined with respect to the overhead wire 100 being held, when the protective tube 101 is caused to hit the overhead wire 100 along the guide bar 113, the protective tube 101 may be greatly damaged from the overhead wire 100 side. Reaction force. Therefore, in the configuration in which the driving tire 116 is omitted, it is necessary to perform operations while pressing the protective tube 101 toward the overhead wire 100 side so as not to fall off the protective tube 101 from the tube-expanding skin 115.

有鑑於此，本發明之目的在於提供一種防護管***器，其為輕便且緊湊之構成，而且可防止***時之防護管之脫落。 In view of this, an object of the present invention is to provide a protective tube inserter, which is light and compact in structure, and can prevent the protective tube from falling off during insertion.

為了達成上述目的，本發明之簡易型防護管***器，係對形成有狹縫之防護管，一面使上述狹縫之一部分擴張一面將該防護管自相對於架空電線而傾斜之方向***者；其特徵在於具備：電線承接部，其緊貼於上述架空電線；***板，其立設於上述電線 承接部，且***上述狹縫內；導軌，其以在一端側與上述電線承接部之間形成銳角之角部之方式設於上述***板之邊緣，且滑動接觸於上述防護管之內壁而進行導引；及增寬器，其設於上述***板之上述角部，以朝上述一端側逐漸增加厚度之方式形成，並且以橫切上述導軌與上述電線承接部之間的方式形成有朝較上述導軌陡峻的方向延長之段差。 In order to achieve the above object, the simple protective tube inserter of the present invention inserts the protective tube from a direction inclined to the overhead wire while expanding a part of the slit to the protective tube formed with a slit; It is characterized by including: a wire receiving portion, which is closely attached to the overhead wire; an insertion plate, which is standingly arranged on the wire receiving portion and inserted into the slit; and a guide rail, which is between one end side and the wire receiving portion Forming the corner of the acute angle at the edge of the insertion plate and slidingly contacting the inner wall of the protective tube for guidance; and a widener at the corner of the insertion plate to face the one end The side is gradually increased in thickness, and a step extending in a steeper direction than the guide rail is formed so as to cross the guide rail and the wire receiving portion.

此外，本發明之簡易型防護管***器，其特徵在於，除了上述構成，還具備：電線夾持部，其藉由與上述***板一體設置之固定夾持片及可動夾持片而自二個方向夾持上述架空電線；及支撐手柄，其於上述電線夾持部之上述可動夾持片側，朝上述一端側延伸設置，用以支撐整體。 In addition, the simple protective tube inserter of the present invention is characterized in that, in addition to the above-mentioned configuration, it further includes: a wire clamping part which is separated from the two by a fixed clamping piece and a movable clamping piece provided integrally with the insertion plate Clamping the overhead wire in two directions; and a support handle extending from the movable clamping piece side of the wire clamping portion toward the one end side to support the whole.

此外，本發明之簡易型防護管***器，其特徵在於，除了上述構成，形成上述增寬器之上述段差之邊緣中的上述一端側之區域，係以相對於上述***板而呈平緩之角度形成。 In addition, the simple protective tube inserter of the present invention is characterized in that, in addition to the above-mentioned configuration, the region on the one end side of the edge forming the step of the widener is at a gentle angle with respect to the insertion plate form.

如上述，根據本發明，於設在導軌與電線承接部之間的***板上之角部的增寬器上形成有朝較導軌陡峻之方向延長之段差，因此，一面使狹縫擴張一面滑動接觸於增寬器上之防護管，沿著段差而被朝架空電線側導引。藉此，由於可將段差作為立足點而將防護管朝架空電線側壓入，因此可防止因前端朝架空電線衝撞時之回推而造成防護管浮起。 As described above, according to the present invention, the widener of the corner portion of the insertion plate provided between the guide rail and the wire receiving portion is formed with a step extending in a steeper direction than the guide rail, so that the slit is expanded while sliding The protective tube that is in contact with the widener is guided toward the overhead wire along the step. In this way, since the step can be used as a foothold to push the protective tube toward the overhead wire side, it is possible to prevent the protective tube from floating due to the pushing back of the front end against the overhead wire.

此外，根據本發明，除了上述功效，電線夾持部係於隔著架空電線而與固定夾持片之相反側之可動夾持片側設置有支撐手柄，其中，該固定夾持片係與***板一體設置，因此可使因通 過遠離架空電線之位置之防護管的重量而搖晃之防護管***器穩定。此外，支撐手柄係朝設置之架空電線之延伸方向即導軌之一端側延伸設置，且可維持與架空電線大致平行的關係，因此可不用換手或大幅改變姿勢地於任意之角度下穩定地握持。 In addition, according to the present invention, in addition to the above-mentioned effects, the wire holding portion is provided with a supporting handle on the side of the movable holding piece opposite to the fixed holding piece across the overhead wire, wherein the fixed holding piece is connected to the insertion plate The integral installation makes it possible to stabilize the protective tube inserter that is shaken by the weight of the protective tube away from the position of the overhead wire. In addition, the support handle is extended toward the extension direction of the installed overhead wire, that is, one end side of the guide rail, and can maintain a substantially parallel relationship with the overhead wire, so it can be stably held at any angle without changing hands or greatly changing the posture hold.

此外，根據本發明，除了上述功效，藉由增寬器上之段差而形成之邊緣中，導軌之一端側即防護管之***側，以相對於***板而呈平緩之角度形成。藉此，被擴張之防護管，不會卡在段差上而可平滑地自增寬器分離，進而移動至架空電線側。 In addition, according to the present invention, in addition to the above-mentioned effects, among the edges formed by the step difference on the widener, one end side of the guide rail, that is, the insertion side of the protective tube, is formed at a gentle angle with respect to the insertion plate. Thereby, the expanded protective tube can be smoothly separated from the widener without being stuck on the step difference, and then moved to the overhead wire side.

以下，使用圖式對本發明之防護管***器進行說明。 Hereinafter, the protective tube inserter of the present invention will be described using drawings.

圖1為自正面側觀察本實施形態之防護管***器1之整體立體圖。此外，圖2為顯示將圖1之防護管***器1之一部分(後述之增寬器8)分解之狀態之整體立體圖。其中，將***防護管之方向作為***側進行說明。此外，適宜參照圖6之防護管101，以如圖6所示之於狹縫107處形成有翅片部109之構成為例，對說明中出現之防護管進行說明。 FIG. 1 is an overall perspective view of the protective tube inserter 1 of this embodiment viewed from the front side. In addition, FIG. 2 is an overall perspective view showing a state in which a part of the protective tube inserter 1 of FIG. 1 (the widener 8 described later) is exploded. Here, the direction in which the protective tube is inserted is described as the insertion side. In addition, it is appropriate to refer to the protective tube 101 of FIG. 6 and take the configuration in which the fin portion 109 is formed at the slit 107 as shown in FIG. 6 as an example to describe the protective tube that appears in the description.

防護管***器1，具有自二個方向夾持架空電線100之電線夾持部10。該電線夾持部10，於上方具有作為固定夾持片之電線承接金屬片2，且於下方側與電線承接金屬件2對向地具有可動夾持片14。電線承接金屬件2係以能沿架空電線100之外面緊貼之方式於下方形成有溝。 The protective tube inserter 1 has a wire holding portion 10 that holds an overhead wire 100 from two directions. The wire holding portion 10 has a wire receiving metal piece 2 as a fixed holding piece on the upper side, and has a movable holding piece 14 on the lower side opposite to the wire receiving metal piece 2. The wire receiving metal piece 2 is formed with a groove below so as to be able to adhere closely to the outer surface of the overhead wire 100.

於電線承接金屬件2上立設有大致三角形之板狀之***板4。***板4係為了***防護管101之狹縫107內以修正扭曲而設置(參照圖6)。 A substantially triangular plate-shaped insertion plate 4 is erected on the wire receiving metal 2. The insertion plate 4 is provided to be inserted into the slit 107 of the protective tube 101 to correct twisting (see FIG. 6 ).

沿著該***板4之上端之邊緣4b而設置有導軌6。導軌6係與***板4之上端之邊緣4b一同進入防護管101內，為了自內側導引防護管101而設置。於本實施形態之構成中，導軌6係採用摩擦係數小之樹脂材料。 A rail 6 is provided along the edge 4b of the upper end of the insertion plate 4. The guide rail 6 enters into the protective tube 101 together with the edge 4b of the upper end of the insertion plate 4, and is provided to guide the protective tube 101 from the inside. In the configuration of this embodiment, the guide rail 6 is made of a resin material with a small friction coefficient.

於形成在導軌6之一端與電線承接金屬件2之間的銳角之角部4a設置有增寬器8。雖未於圖1顯示，但該增寬器8係設於***板4之兩面。該增寬器8係可裝卸地安裝於***板4。圖2之分解圖顯示自***板4取下之狀態。可容易藉由2根螺栓進行拆卸。 A widener 8 is provided at a corner 4a formed at an acute angle between one end of the guide rail 6 and the wire receiving metal 2. Although not shown in FIG. 1, the widener 8 is provided on both sides of the insertion plate 4. The widener 8 is detachably attached to the insertion plate 4. The exploded view of FIG. 2 shows the state removed from the insertion plate 4. It can be easily disassembled by 2 bolts.

由圖1可知，上述電線承接金屬件2，係以於增寬器 8附近擴大寬度之方式形成。由於形成為此種構成，當防護管101滑動於導軌6上而朝架空電線100側移行時，可防止架空電線100之包覆層因防護管101而損傷之情形。 As can be seen from FIG. 1, the above-mentioned wire receiving metal 2 is formed in such a manner that the width is enlarged in the vicinity of the widener 8. Due to such a structure, when the protective tube 101 slides on the guide rail 6 and moves toward the overhead wire 100 side, the coating layer of the overhead wire 100 can be prevented from being damaged by the protective tube 101.

增寬器8之寬度，係被規定為能使防護管101相對於架空電線100平滑地移動之尺寸。在此被設定為較導軌6之寬度大且較電線承接金屬件2之寬度略小之尺寸。此外，於增寬器8之側面形成有朝與導軌6相同之方向傾斜之段差8e(容待後續使用圖3進行說明)。 The width of the widener 8 is defined as a size that enables the shield tube 101 to move smoothly relative to the overhead wire 100. Here, it is set to a size larger than the width of the guide rail 6 and slightly smaller than the width of the wire receiving metal member 2. In addition, a step 8e inclined in the same direction as the guide rail 6 is formed on the side of the widener 8 (to be described later using FIG. 3).

其次，對增寬器8之形狀詳細地進行說明。 Next, the shape of the widener 8 will be described in detail.

圖3為顯示2個零件中的一個增寬器8之圖，(a)為前視圖，(b)為俯視圖，(c)為仰視圖，(d)為右側視圖。再者，為了方便說明，放大顯示(d)之右側視圖。此外，藉由對以上之說明中涉及之段差8e所顯示之面加上斜線，以明示位置關係。防護管101之***側為紙面之左側。 FIG. 3 is a diagram showing one widener 8 of the two parts, (a) is a front view, (b) is a top view, (c) is a bottom view, and (d) is a right side view. In addition, for convenience of explanation, the right side view of (d) is enlarged. In addition, by adding diagonal lines to the surface displayed by the step 8e involved in the above description, the positional relationship is clearly indicated. The insertion side of the protective tube 101 is the left side of the paper.

首先，參照圖3(a)之前視圖，於增寬器8上顯示有4個面。其等面之中的位於紙面最右側的面，係形成有撈起部8a之面，該撈起部8a係供為了朝架空電線100***而移送至導軌6(參照圖1)上之防護管101開始乘上者。最先移送而至之防護管101之開口側之狹縫107，藉由該撈起部8a而以被撈起之方式擴張。 First, referring to the front view of FIG. 3( a ), four faces are displayed on the widener 8. Among the equal surfaces, the rightmost surface of the paper surface is a surface formed with a lifting portion 8a for the protection tube to be transferred to the guide rail 6 (refer to FIG. 1) for insertion into the overhead wire 100 101 started to ride. The slit 107 of the opening side of the protective tube 101 which is transferred first is expanded by the scooping portion 8a so as to be scooped up.

朝***側連接於該撈起部8a之面，係由第一漸變部8b形成之面。若以***板4(參照圖1)作為基準而進行觀察，第一漸變部8b，係由較撈起部8a平緩之傾斜形成。藉由撈起部8a而得以擴張之狹縫107，隨著防護管101朝***側移動而乘上至第一漸變部8b且被平緩地擴張。 The surface connected to the lifting portion 8a toward the insertion side is a surface formed by the first tapered portion 8b. If the insertion plate 4 (refer to FIG. 1) is used as a reference for observation, the first gradual change portion 8 b is formed to be inclined more gently than the lifting portion 8 a. The slit 107, which is expanded by the lifting portion 8a, rides on the first gradient portion 8b as the protective tube 101 moves toward the insertion side and is gradually expanded.

於第一漸變部8b之上方顯示之面，係第二漸變部8c之側面。第二漸變部8c係以較第一漸變部8b略微增大傾斜之方式形成。藉此，於兩者間形成段差8e。該傾斜角之大小差異，顯示於圖3(b)。其中，以虛線顯示第一漸變部8b之傾斜面。如此，因傾斜角之大小差異而形成之段差8e，於圖3(c)之仰視圖中被施以斜線表示。同樣地，於圖3(d)中也對形成段差8e之面施加斜線。 The surface shown above the first gradient portion 8b is the side surface of the second gradient portion 8c. The second gradual change portion 8c is formed so as to slightly increase the inclination compared to the first gradual change portion 8b. As a result, a step 8e is formed between the two. The size difference of the tilt angle is shown in Fig. 3(b). Among them, the inclined surface of the first gradation portion 8b is shown by a dotted line. In this way, the step 8e formed due to the difference in the inclination angle is indicated by diagonal lines in the bottom view of FIG. 3(c). Similarly, in FIG. 3(d), a diagonal line is applied to the surface where the step 8e is formed.

最後，於第二漸變部8c之左側顯示之面，係規定增寬器8之擴張寬度之寬度規定部8d之外表面。於增寬器8中，該寬度規定部8d最朝寬度方向突出。於本實施形態之構成中，寬度規定部8d之外表面係與***板4大致平行地形成。 Finally, the surface shown on the left side of the second gradation portion 8c is the outer surface of the width defining portion 8d that defines the expanded width of the widener 8. In the widener 8, the width defining portion 8d protrudes most in the width direction. In the configuration of this embodiment, the outer surface of the width defining portion 8d is formed substantially parallel to the insertion plate 4.

以下，對使用狀態之作用進行說明。 Hereinafter, the function of the use state will be described.

圖4為顯示防護管***器1之使用狀態之圖，(a)顯示防護管101之前端位於***板4上之狀態，(b)顯示防護管101之前端位於增寬器8上之狀態。 4 is a diagram showing the use state of the protective tube inserter 1, (a) shows a state where the front end of the protective tube 101 is located on the insertion plate 4, and (b) shows a state where the front end of the protective tube 101 is located on the widener 8.

由樹脂材料形成之防護管101之狹縫107，於不被施加外力之狀態下會閉合，因此在到達增寬器8之前，該防護管101一面相對於***面滑動接觸一面被移送而來。由於導軌6係形成為較該閉合之狹縫107略大，因此即使為粗略之操作仍不會脫落而可到達增寬器8。 The slit 107 of the protective tube 101 formed of a resin material is closed when no external force is applied. Therefore, before reaching the widener 8, the protective tube 101 is transferred while sliding in contact with the insertion surface. Since the guide rail 6 is formed to be slightly larger than the closed slit 107, even if it is a rough operation, it will not fall off and the widener 8 can be reached.

如圖4(b)所示，若防護管101之前端到達增寬器8，則如上述，首先，狹縫107之開口側乘上撈起部8a，朝第一漸變部8b移動。在此，返回圖3(a)，形成於撈起部8a與第一漸變部8b之間的稜線，係朝與導軌6相同側傾斜，且以較導軌6陡峻之傾斜度形成。藉此，當自撈起部8a朝第一漸變部8b移動時，防護管101 之開口之狹縫107，沿著稜線被朝架空電線100側引導。如此，至少以不會自導軌6脫離之方式被移送而來之防護管101，無論在哪一高度上，皆會在第一階段藉由撈起部8a與第一漸變部8b之間的稜線而被朝架空電線100側修正位置。 As shown in FIG. 4(b), if the front end of the protective tube 101 reaches the widener 8, as described above, first, the opening side of the slit 107 rides on the lifting portion 8a and moves toward the first gradation portion 8b. Here, returning to FIG. 3( a ), the ridgeline formed between the scooping portion 8 a and the first gradation portion 8 b is inclined toward the same side as the guide rail 6 and is formed with a steeper slope than the guide rail 6. As a result, when the self-lifting portion 8a moves toward the first gradient portion 8b, the slit 107 of the opening of the protective tube 101 is guided toward the overhead wire 100 side along the ridge line. In this way, at least the protective tube 101 that is transferred in such a way as not to detach from the guide rail 6 will pass through the ridgeline between the scooping portion 8a and the first gradual transition portion 8b at the first stage at any height The position is corrected toward the overhead wire 100 side.

接著，當防護管101之狹縫107通過第一漸變部8b上時，如上述，由於在與第二漸變部8c之間形成段差8e，因此，狹縫107之端部抵接於該段差8e上。抵接之狹縫107沿形成於段差8e之邊緣而被引導。其中，關於該邊緣，將第一漸變部8b與第二漸變部8c之間的邊緣稱為第一邊緣8f，將寬度規定部8d與第一漸變部8b之間的邊緣稱為第二邊緣8g。 Next, when the slit 107 of the protective tube 101 passes through the first gradation portion 8b, as described above, since the step 8e is formed between the second gradation portion 8c and the end of the slit 107 abuts on the step 8e on. The abutting slit 107 is guided along the edge formed at the step 8e. With regard to this edge, the edge between the first gradation portion 8b and the second gradation portion 8c is called the first edge 8f, and the edge between the width regulation portion 8d and the first gradation portion 8b is called the second edge 8g .

亦即，自撈起部8a移送而至之防護管101，首先沿第一邊緣8f移動於第一漸變部8b上。該第一邊緣8f與上述之稜線相同，係朝與導軌6相同之方向傾斜，且以朝較導軌6陡峻之傾斜方向延伸之方式形成。但是，由於傾斜度較稜線小，因此被平緩地朝架空電線100側引導。 That is, the protective tube 101 transferred from the lifting portion 8a first moves on the first gradation portion 8b along the first edge 8f. The first edge 8f is the same as the aforementioned ridgeline, and is inclined in the same direction as the guide rail 6 and is formed to extend in a steeper inclined direction than the guide rail 6. However, since the inclination is smaller than the ridgeline, it is gently guided toward the overhead wire 100 side.

於防護管101滑動接觸於第一漸變部8b上之階段，防護管101之翅片部109之一部分開始與電線承接金屬件2之上側卡合。於自撈起部8a朝第一漸變部8b行進且將狹縫寬度107逐漸擴大之階段，翅片部109沿著架空電線100之外徑而擴大為充分之寬度。如此，架空電線100側之擴張作用逐漸成為支配性，因此防護管101可自增寬器8朝架空電線100側平滑地轉移。 At the stage when the protective tube 101 slidingly contacts the first gradation portion 8b, a part of the fin portion 109 of the protective tube 101 starts to engage with the upper side of the wire receiving metal 2. At a stage where the width of the slit 107 is gradually enlarged from the lifting portion 8a toward the first gradation portion 8b, the fin portion 109 is expanded to a sufficient width along the outer diameter of the overhead wire 100. In this way, the expansion effect on the side of the overhead wire 100 gradually becomes dominant, so the protective tube 101 can be smoothly transferred from the widener 8 toward the side of the overhead wire 100.

於本實施形態之構成中，如上述，由於第一邊緣8f之***側連接於以***板4為基準之傾斜較第一邊緣8f平緩之第二邊緣8g，因此，於翅片部109充分地朝架空電線100側轉移之狀 態下，防護管101之內壁可自第一邊緣8f分離而不會卡住。如此，關於形成在增寬器8之邊緣，本發明之特徵在於：藉由以自傾斜較大的第一邊緣8f朝在***側傾斜較小之第二邊緣8g連接之方式形成，可使防護管101之前端之狹縫107平滑地越過架空電線100。 In the configuration of this embodiment, as described above, since the insertion side of the first edge 8f is connected to the second edge 8g whose slope is gentler than the first edge 8f with respect to the insertion plate 4, the fin portion 109 is sufficiently In the state of being transferred toward the overhead wire 100 side, the inner wall of the protective tube 101 can be separated from the first edge 8f without being stuck. As such, regarding the edge formed on the widener 8, the present invention is characterized in that by forming the first edge 8f with a larger inclination toward the second edge 8g with a smaller inclination on the insertion side, protection can be achieved The slit 107 at the front end of the tube 101 smoothly crosses the overhead wire 100.

其次，使用圖5進行前視時之動作說明。 Next, the operation during the front view will be described using FIG. 5.

圖5為比較通過增寬器8之防護管101之狀態之圖，(a)顯示防護管101之前端通過之狀態，(b)顯示防護管101之中央部通過之狀態。其中，為了方便說明，以虛線顯示防護管101之位置，並對翅片部109之位置施以斜線而顯示。 FIG. 5 is a diagram comparing the state of the protective tube 101 passing through the widener 8, (a) shows a state where the front end of the protective tube 101 passes, and (b) shows a state where the central portion of the protective tube 101 passes. For convenience of description, the position of the shield tube 101 is shown by a dotted line, and the position of the fin portion 109 is shown by a diagonal line.

參照圖5(a)，當防護管101之前端被***時，防護管101沿導軌6直線突出至直到前端之開口部107之邊緣抵接於架空電線100之位置為止。因此，突出且抵接電線承接金屬件2之防護管101，因來自電線承接金屬件2之反作用力而受到朝自架空電線100分離之方向的力。如此，於未充分地朝架空電線100側移行之階段，因來自電線承接金屬件2(或架空電線100)之回推，防護管101處於容易自導軌6脫離之狀態，這點在習知技術中被當作一項課題。然而，於本實施形態之構成中，如上述，在至翅片部109充分地朝架空電線100側卡合為止，換言之，至翅片部109與架空電線100交叉為止，會因第一邊緣8f之朝架空電線100側按壓之作用發揮，因而可防止防護管101之脫落。 Referring to FIG. 5( a ), when the front end of the protective tube 101 is inserted, the protective tube 101 protrudes straight along the guide rail 6 until the edge of the opening 107 at the front end abuts against the position of the overhead wire 100. Therefore, the protective tube 101 that protrudes and abuts the wire receiving metal member 2 receives a force in a direction separating from the overhead wire 100 due to the reaction force from the wire receiving metal member 2. In this way, at the stage of not fully moving toward the overhead wire 100 side, the protective tube 101 is in a state where it is easily detached from the guide rail 6 due to the back push from the wire receiving metal 2 (or the overhead wire 100), which is known in the art Is regarded as a subject. However, in the configuration of this embodiment, as described above, until the fin portion 109 is sufficiently engaged toward the overhead wire 100 side, in other words, until the fin portion 109 crosses the overhead wire 100, the first edge 8f The function of pressing toward the side of the overhead wire 100 is exerted, so that the protection tube 101 can be prevented from falling off.

其次，參照圖5(b)，於防護管101之前端裝入架空電線100，且防護管101之中間位置通過增寬器8附近之階段，雖一面略微產生彎曲地追蹤導軌6，但一面也會於導軌6與電線承接金屬件2之交叉位置上產生上浮。但於該階段中，由於防護管101已 於***側咬入架空電線100，因此防護管101不會脫落。 Next, referring to FIG. 5(b), when the overhead wire 100 is installed at the front end of the protective tube 101, and the middle position of the protective tube 101 passes near the widener 8, although the guide rail 6 is slightly curved on one side, it is also on the other side. The floating will occur at the intersection of the guide rail 6 and the wire receiving metal 2. However, at this stage, since the protective tube 101 has bitten into the overhead wire 100 on the insertion side, the protective tube 101 will not come off.

其中，關於翅片部109與第二邊緣8g之間的位置關係，比較圖5(a)、(b)之狀態。於圖5(a)中，翅片部109之上端側即狹縫107之位置，逐漸自第一邊緣8f分離且朝第二邊緣8g上移動。亦即是防護管101之前端逐漸受到來自電線承接金屬件2之回推之階段(阻力成為最大之階段)，也是為了抑制上浮而獲得充分之力之階段。 Among them, regarding the positional relationship between the fin portion 109 and the second edge 8g, the states of FIGS. 5(a) and (b) are compared. In FIG. 5(a), the upper end side of the fin portion 109, that is, the position of the slit 107, gradually separates from the first edge 8f and moves toward the second edge 8g. That is, the stage where the front end of the protective tube 101 is gradually pushed back from the wire receiving metal 2 (the stage where the resistance becomes maximum) is also the stage where sufficient force is obtained to suppress the floating.

與此相對，於圖5(b)中，雖然防護管101略微上浮，但於已朝架空電線100側移動之部分中，被擴大之狹縫107藉由復原力而被施加欲閉合之力。亦即，藉由該復原力可抑制上浮，因此於該階段，增寬器8與防護管101之摩擦會變成問題。但是，如上述，翅片部109與重疊之第二邊緣8g之間幾乎不產生諸如相對於第一邊緣8f之摩擦般之阻擋因素。因此一旦架空電線100被裝入防護管101，則與第一邊緣8f之間的摩擦會急遽減小，因此可幾乎無阻力地陸續送出防護管101。 On the other hand, in FIG. 5(b), although the protective tube 101 floats slightly, in the portion that has moved toward the overhead wire 100 side, the enlarged slit 107 is applied with the force to be closed by the restoring force. That is, the restoring force can suppress the floating, so at this stage, the friction between the widener 8 and the protective tube 101 becomes a problem. However, as described above, there is hardly any blocking factor such as friction with the first edge 8f between the fin portion 109 and the overlapping second edge 8g. Therefore, once the overhead wire 100 is installed in the protective tube 101, the friction with the first edge 8f is sharply reduced, so that the protective tube 101 can be sent out almost without resistance.

如上述，根據本實施形態之防護管***器1，可防止防護管101之損傷，並且可防止因朝架空電線100之撞擊而引起之上浮，並且還可有效地抑制阻擋因素，而可平滑地送入防護管101。 As described above, according to the protective tube inserter 1 of the present embodiment, the damage of the protective tube 101 can be prevented, and the upward floating caused by the impact on the overhead wire 100 can be prevented, and the blocking factor can also be effectively suppressed, so that the送入保护管101。 Send into the protective tube 101.

如此，由於可將導軌6配置於架空電線100之上方而平滑地***防護管101，因此，不需要如習知之大多採用之將導軌6配置於下方之構成般，與導軌6對向地配置導輥等，而可簡單且輕量地構成整體。 In this way, since the guide rail 6 can be arranged above the overhead wire 100 and smoothly inserted into the protective tube 101, there is no need to arrange the guide rail 6 to face the guide rail 6 as is conventionally used to arrange the guide rail 6 below Rollers, etc., and the whole can be formed simply and lightly.

此外，即使於以導軌6位於架空電線100之下方之方式使整體反轉而使用本實施形態之防護管***器1的情況下，仍可 藉由第一邊緣8f及第二邊緣8g(主要為第一邊緣8f)作用將防護管101朝上方之架空電線100側抬起的力，因此不會使防護管101脫落而可安全地進行作業。 In addition, even when the protective tube inserter 1 of the present embodiment is used in such a manner that the guide rail 6 is positioned below the overhead wire 100 and the whole is reversed, the first edge 8f and the second edge 8g (mainly The first edge 8f) acts to lift the protective tube 101 upward toward the overhead wire 100 side, so the protective tube 101 can be safely operated without falling off.

順便一提，於導軌6配置於架空電線100之上方之狀態下進行作業之情況下，防護管101之重量係被附加於導軌6上。 Incidentally, when the rail 6 is disposed above the overhead wire 100, the weight of the protective tube 101 is added to the rail 6.

與此相對，由於防護管***器1藉由電線夾持部10而被固定於架空電線100，因此大幅遠離架空電線100之導軌6之一側(與上述角部4a側之一端相反之另一端側)容易變得不穩定。 On the other hand, since the protective tube inserter 1 is fixed to the overhead wire 100 by the wire clamping portion 10, it is far away from one side of the guide wire 6 of the overhead wire 100 (the other end opposite to one end of the above-mentioned corner 4a side) Side) easily become unstable.

但是，於本實施形態之構成中，由於在電線夾持部10之可動夾持片14側設置有支撐手柄16(參照圖1)，因此可有效地抑制導軌6側之防護管101之振動。 However, in the configuration of the present embodiment, since the support handle 16 (see FIG. 1) is provided on the movable holding piece 14 side of the wire holding portion 10, the vibration of the shield tube 101 on the guide rail 6 side can be effectively suppressed.

此外，由於朝沿架空電線100之延伸方向之方向配置支撐手柄16的延伸方向，因此於抑制防護管***器1欲以架空電線100作為中心而旋轉之動作之情況下，可保持相對於架空電線100之平行姿勢。藉此，可防止握持支撐手柄16之手腕不自然扭轉之情形。 In addition, since the extension direction of the support handle 16 is arranged in the direction along the extension direction of the overhead wire 100, it is possible to maintain relative to the overhead wire when the protective tube inserter 1 is prevented from rotating about the overhead wire 100 as a center 100 parallel poses. Thereby, the situation that the wrist holding the support handle 16 is not twisted naturally can be prevented.

再者，以上所述之構成，係本發明之一實施例而已，還包含如下之變形。 In addition, the above-mentioned configuration is an embodiment of the present invention, and includes the following modifications.

於上述實施形態中，例示了形成於增寬器8之側面之邊緣，在相對於***板4之傾斜度比較陡峻之第一邊緣8f之***側連設有較其平緩傾斜的第二邊緣8g之構成。但是，該邊緣也可直線性地形成。 In the above embodiment, an edge formed on the side of the widener 8 is exemplified, and a second edge 8g that is gently inclined relative to the insertion edge of the first edge 8f that has a steeper slope with respect to the insertion plate 4 is connected Composition. However, the edge may be formed linearly.

此外，於上述實施形態中，例示了連設於增寬器8之第一漸變部8b而形成有撈起部8a之構成。但是，也可為自*** 板4直接朝第一漸變部8b連接之構成。再者，藉由形成撈起部8a，可平緩地設置第一漸變部8b之傾斜。 In addition, in the above-mentioned embodiment, the configuration in which the scooping portion 8a is formed in the first gradation portion 8b of the widener 8 is exemplified. However, it may be configured to connect directly from the insertion plate 4 toward the first gradation portion 8b. Furthermore, by forming the scooping portion 8a, the inclination of the first gradual changing portion 8b can be provided gently.

此外，於上述實施形態中，例示了支撐手柄16以朝與架空電線100大致平行之方向延伸之方式配置之構成。但是，只要為朝導軌6之一端側即***側延伸設置之構成，支撐手柄16也可不必完全平行於架空電線100。 In addition, in the above-described embodiment, the configuration in which the support handle 16 is arranged to extend in a direction substantially parallel to the overhead wire 100 is exemplified. However, as long as it is configured to extend toward one end side of the guide rail 6, that is, the insertion side, the support handle 16 need not be completely parallel to the overhead wire 100.

此外，於上述實施形態中，例示了電線承接金屬件2於電線夾持部10中被作為與可動夾持片14對向設置之固定夾持片而構成之例子。但是，也可為分開設置為了保護架空電線100而設之電線承接金屬件2及固定架空電線100之固定夾持片之構成。 In addition, in the above-mentioned embodiment, an example in which the wire receiving metal 2 is configured as a fixed clamping piece provided opposite to the movable clamping piece 14 in the wire clamping portion 10 is exemplified. However, it may be configured to separately provide the wire receiving metal 2 provided for protecting the overhead wire 100 and the fixed clamping piece for fixing the overhead wire 100.

(產業上之可利用性) (Industry availability)

本發明之防護管***器1，可使防護管101相對於架空電線100平滑地滑動，因此不僅具有***防護管101之用途，而且對拔取防護管101之作業也有用。 The protective tube inserter 1 of the present invention can smoothly slide the protective tube 101 relative to the overhead wire 100, so it is not only useful for inserting the protective tube 101, but also useful for the operation of pulling out the protective tube 101.
