この発明に係るねじれ防止ダンパーの取外し機により、ねじれ防止ダンパーを取外す際には、まず遠隔操作器(一般には無線操作器)又は機枠設置操作器からの操作信号(起動信号)に基づいて、前後の各車輪が回転駆動し、架空送電線に沿って前進する。この前進は、前側の車輪が取外すべきねじれ防止ダンパーの送電線クランプの上部を越えた後に、ダンパー検出センサーのねじれ防止ダンパーの検出信号に基づいて停止する。この時前後の車輪間の中央部にねじれ防止ダンパーの送電線クランプが位置するとともにねじれ防止ダンパーの真下にダンパー取外し装置が位置する状態になる。続いて制御信号に基づいて、ダンパー取外し装置の円筒昇降柱が、昇降の中間域を所定の高さ上昇(初期上昇)する。これによりねじれ防止ダンパーは、二連重りが重り受皿で不動状態に支持された後、所定高さ持上げられ、押えボルトの頭部がボルト取外し装置のボックスレンチのレンチボックスと正対するダンパー位置決め状態になる。   When removing the torsion prevention damper by the torsion prevention damper remover according to the present invention, first, based on an operation signal (start signal) from a remote operation device (generally a wireless operation device) or a machine frame installation operation device, The front and rear wheels are driven to rotate and move forward along the overhead power transmission line. This forward movement is stopped based on the detection signal of the torsion prevention damper of the damper detection sensor after the front wheel has passed over the upper part of the transmission line clamp of the torsion prevention damper to be removed. At this time, the transmission line clamp of the torsion preventing damper is located at the center between the front and rear wheels, and the damper removing device is located just below the torsion preventing damper. Subsequently, on the basis of the control signal, the cylindrical lifting column of the damper removing device raises a predetermined height (initial increase) in the middle region of the lifting. As a result, the torsion prevention damper is supported in a state where the double weight is fixedly supported by the weight receiving tray and then lifted to a predetermined height, so that the head of the presser bolt is in a damper positioning state in which the head of the bolt removing device faces the wrench box of the box wrench. Become.

次いで、ボルト取外し装置のレンチ進退台が、ねじれ防止ダンパーに向かって前進し、レンチ前進検出センサーの検出信号に基づいて前進を停止する。この前進の最終段階においては、ボックスレンチのレンチボックスが押えボルトの頭部に嵌合して後方へ押圧されるとともに、レンチシャンクがばねに抗して収縮(後退)し、続いて後端部がレバー後端部追従ガイドエッジの後部から前部へと追従係合しながら前進してきて前傾揺動自在になったレンチボックス掛止めレバーの先端のボックスレンチ掛止めフックが、レンチボックス掛止めレバーの前傾揺動力のままに内角近傍部がレンチボックスの最上部の外周面部に当接するまで、レンチボックスの直前部に下降して、レンチシャンクを収縮状態に保持する状態になる。この後電動ボックスレンチの作動により、レンチシャンクが所定量回転して、押えボルトを緩めると同時に、進退ねじ軸が逆転して、レンチ進退台を後退し、押えボルトを送電線クランプのねじ穴から引き抜く。 Next, the wrench advancement / retraction base of the bolt removing device advances toward the torsion prevention damper, and the advancement is stopped based on the detection signal of the wrench advancement detection sensor. In the final stage of the forward, while being pressed rearward by fitting the head of the bolt holding wrench box lug wrench, the wrench shank against the spring to contract (retreat), followed by the rear end portion The lever wrench hanging hook at the tip of the wrench box hanging lever that has moved forward and engaged forward and backward from the rear edge to the front of the lever trailing edge tracking guide edge With the forward tilting and swinging force of the lever, the inner vicinal part is lowered to the front part of the wrench box until it comes into contact with the outermost surface part of the uppermost part of the wrench box, and the wrench shank is held in the contracted state. After that, the wrench shank rotates a predetermined amount by operating the electric box wrench to loosen the presser bolt.At the same time, the advance / retreat screw shaft reverses, the wrench advancement / retreat base moves backward, and the presser bolt is removed from the screw hole of the transmission line clamp. Pull out.

レンチ進退台が後退する間に、レンチボックス掛止めレバーの後端部がレバー後端部追従ガイドエッジの前部及びここから後部への追従係合によりレンチボックス掛止めレバーの前傾揺動力に抗して押下げられて、レンチボックス掛止めフックがレンチボックス上にその上部の外周面部に臨む状態まで上昇し、これによって収縮状態のレンチシャンクがばねの作用力により瞬時に伸長するため、押えボルトの頭部はレンチボックスから離脱し、この結果押えボルトは自重により落下して、下方のダンパー受容器内に収容される。 While the wrench advancement / retraction base moves backward, the rear end of the wrench box latching lever is moved forward and swinging forward by the front edge of the lever rear end follower guide edge and from the rear to the rear. The wrench box latching hook is lifted to the state where it faces the outer peripheral surface of the upper part of the wrench box , and the wrench shank in the contracted state is instantly extended by the spring force. The head of the bolt is detached from the wrench box. As a result, the presser bolt falls by its own weight and is accommodated in the lower damper receiver.

レンチ進退台の後退が進むと、レンチ後退検出センサーの検出信号に基づいて、進退ねじ軸の逆転が停止する。この後、ダンパー取外し装置の円筒昇降柱が、ガイドピンと上下に真直ぐにのびる縦ガイド孔との係合により、押えボルトを取外されたねじれ防止ダンパー(すなわちダンパー本体)とともに、その昇降の上部域直前までを真直ぐに上昇した後、昇降の上部域において、ガイドピンと略90°軸周りの傾斜勾配でのびる縦ガイド孔部との係合により、略90°回転しながら上昇する。これにより送電線クランプは架空送電線から完全に離脱する。   When the wrench advance / retreat base moves backward, the reverse rotation of the advance / retreat screw shaft stops based on the detection signal of the wrench reverse detection sensor. After this, the cylindrical lifting column of the damper removing device is engaged with the guide pin and the vertical guide hole extending straight up and down, together with the torsion preventing damper (ie, the damper main body) from which the presser bolt is removed, and the upper region of the lifting and lowering. After ascending straight up to just before, in the upper region of the ascending / descending, it rises while rotating by approximately 90 ° due to the engagement between the guide pin and the vertical guide hole extending at an inclined gradient around the approximately 90 ° axis. As a result, the transmission line clamp is completely detached from the overhead transmission line.

続いて昇降ねじ軸が逆転して、円筒昇降柱は、ダンパー本体とともに、昇降の上部域を逆回転しながら下降した後、昇降の中間域を真直ぐに下降する。この下降が昇降の下部域に入ると、重り受皿が、前端部又は後端部の重り受皿ストッパーに当接して、その下降を制止されるため、後ろ下がり又は前下がりに傾斜する。これによりダンパー本体は二連重りを介して後方又は前方に滑り落ちて、ダンパー受容器内に受容され、目的のねじれ防止ダンパーの取外しが完了する。   Subsequently, the elevating screw shaft is reversed, and the cylindrical elevating column descends with the damper body while reversely rotating the upper region of the elevating operation, and then descends straight in the intermediate region of the elevating operation. When this descending enters the lower part of the ascending / descending, the weight receiving tray comes into contact with the weight receiving tray stopper at the front end portion or the rear end portion and is restrained from descending, so that it tilts backward or downward. As a result, the damper main body slides back or forward via the double weight, is received in the damper receiver, and the removal of the target anti-twisting damper is completed.

When the wrench shank 64 is contracted, the vicinity of the inner corner of the wrench box retaining hook 70 (the lower surface near the inner corner) abuts the outermost surface of the uppermost portion of the wrench box 65, and the wrench box is latched. The hook 70 has an unbalanced form of a forward and backward swinging type front-rear moment that can be lowered to the front part of the wrench box 65 (see the phantom line in FIG. 5) .

レンチ進退用サイドガイド52の長さ方向の中間部には、ボックスレンチ62を跨ぐゲート形ガイド取付け枠72が取り付けてあり、このガイド取付け枠72のボックスレンチ62跨ぎ部内(ゲート内の上部)には、前部が前方に向かってボックスレンチ62から離隔するように上り勾配でのびるとともに後部が後方に向かってボックスレンチ62に近い位置を水平にのびるレバー後端部追従ガイドエッジ73a、73bを備えた側面から見て変形した逆台形状のレバー揺動ガイド73が取り付けてある(図1、図7参照)。このレバー揺動ガイド73のレバー後端部追従ガイドエッジに対しては、レンチボックス掛止めレバー69の後端部69aは、レンチ進退台55が待機位置(図1、図7参照)から初期の前進位置にある間は後部の73bに係合して、レンチボックス掛止めフック70をその下端がレンチボックス64の伸長により前進位置にあるレンチボックス65の上部の外周面部に臨むレンチボックス65上の位置に保持し(特に図5参照。但しこの図では簡略化のために、ボックスレンチ掛止めフック70の下端がレンチボックス65の外周面部に当接しているかのような状態で示してある)、これに続くレンチ進退台55の中間の前進時には、レンチボックス掛止めレバー69の前傾揺動力のままに後部の73bから前部の73aに係合し、レンチボックス掛止めフック70をその下端がレンチボックス65の上部の外周面部に当接する状態にした後、前部の73aを離れて、レンチボックス掛止めレバー69をレンチボックス65によりそれ以上の前傾を阻止された状態にする。この後レンチ進退台55の最前進時には後述するようにレンチボックス65付きレンチシャンク64のばね66に抗した収縮、後退により、レンチボックス掛止めフック70は内角近傍部がレンチボックス65の最上部の外周面部に当接する状態でレンチボックス65の直前部に下降(図5仮想線参照)可能になる一方、レンチ進退台55の後退時には、その中間においてレンチボックス掛止めレバー69の後端部69aが前部の73a及びそこから後部の73bへと係合して、レンチボックス掛止めレバー69の前傾揺動力に抗して先端のレンチボックス掛止めフック70をレンチボックス65の直前部からレンチボックス65上に上昇させる(図5実線参照)A gate-type guide mounting frame 72 that straddles the box wrench 62 is attached to the middle portion of the wrench advancement / retraction side guide 52 in the length direction, and the guide mounting frame 72 is placed in the portion straddling the box wrench 62 (upper part in the gate) . Includes lever rear end follower guide edges 73a and 73b that extend at an upward slope so that the front part is separated from the box wrench 62 toward the front and the rear part extends horizontally toward the rear toward the box wrench 62. An inverted trapezoidal lever swing guide 73 deformed when viewed from the side is attached (see FIGS. 1 and 7) . With respect to the lever rear end tracking guide edge of the lever swinging guide 73, the rear end portion 69a of the wrench box latching lever 69 is the initial position of the wrench advancement / retraction base 55 from the standby position (see FIGS. While in the forward movement position, it engages with the rear 73b, and the lower end of the wrench box retaining hook 70 faces the outer peripheral surface of the upper part of the wrench box 65 in the forward movement position due to the extension of the wrench box 64. (In particular, for the sake of simplicity, the lower end of the box wrench latching hook 70 is shown as if it is in contact with the outer peripheral surface of the wrench box 65.) during the subsequent middle wrench retractable stand 55 forward, engages the left to the rear of 73b before傾揺power wrench box latch lever 69 to the front of the 73a, wrench After the hook hook 70 is brought into contact with the outer peripheral surface of the upper portion of the wrench box 65, the front 73 a is released and the wrench box hook lever 69 is tilted further forward by the wrench box 65. Get blocked. After that, when the wrench advancement / retreat base 55 is moved forward most, the wrench box retaining hook 70 has its inner corner near the uppermost portion of the wrench box 65 due to contraction and retraction against the spring 66 of the wrench shank 64 with the wrench box 65 as described later. While being in contact with the outer peripheral surface portion, it is possible to descend to the front portion of the wrench box 65 (see the phantom line in FIG. 5), while when the wrench advancement / retraction base 55 is retracted , the rear end portion 69a of the wrench box latching lever 69 is in the middle. The front wrench hook 70 is engaged with the front portion 73a and the rear portion 73b, and the front wrench box hooking hook 70 is moved from the front portion of the wrench box 65 against the forward tilting swinging force of the wrench box hook lever 69. 65 (see the solid line in FIG. 5) .

また両サイドガイド52の上端には、その長さ方向に間隔をおいて、それぞれ相互に対向する発光器と受光器とからなる光電センサーからなるレンチ前進検出センサー74とレンチ後退検出センサー75が取り付けてあり、これによるレンチ進退台55の後端部の検出を介して、レンチ進退台55の所定の位置までの前進と後退を検出するようになっている。   Further, a wrench advance detection sensor 74 and a wrench retraction detection sensor 75, which are photoelectric sensors each composed of a light emitter and a light receiver, which are opposed to each other, are attached to the upper ends of both side guides 52 at intervals in the length direction. Thus, the forward and backward movement of the wrench advance / retreat base 55 to a predetermined position is detected through the detection of the rear end of the wrench advance / retreat base 55.

図1、図2に示すように、機枠16の基枠19には、略その全域にわたって開口する可撓性の網袋製のダンパー受容器76が垂下させてあるとともに、ダンパー取外し装置30の前部に隣接する基枠19部上には、円筒基柱32の上端部近傍からダンパー受容器76に向かって下方にのびるダンパー本体滑落用のダクト状のガイドシュート77設置してあり、またボルト取外し装置50のレンチ進退用サイドガイド52の前端部には、ガイドシュート77上に臨む押えボルト滑落用のガイドシュート78取り付けてある。 As shown in FIG. 1 and FIG. 2, the base frame 19 of the machine frame 16 is suspended by a flexible mesh bag-made damper receiver 76 that opens over substantially the entire area of the machine frame 16, and the damper removing device 30. A duct-shaped guide chute 77 for sliding down the damper main body extending downward from the vicinity of the upper end portion of the cylindrical base pillar 32 toward the damper receiver 76 is installed on the base frame 19 adjacent to the front portion. A guide chute 78 for sliding down the presser bolt facing the guide chute 77 is attached to the front end of the wrench advance / retreat side guide 52 of the bolt removing device 50.

さらに機枠16の基枠19上には、逐次制御装置本体とともに無線のアンテナ付き遠隔操作器(発信器)から発信される操作信号を受信可能なアンテナ付き受信器を含むとともに主操作(制御)盤を付設した制御ユニット(制御ボックス)79と、バッテリー80が設置してあるとともに、機枠16の後側の縦枠18の上端部には、手動操作用の起動ボタン82と緊急停止ボタン83を有する補助操作盤81が取り付けてある。   Further, the base frame 19 of the machine frame 16 includes a receiver with an antenna capable of receiving an operation signal transmitted from a wireless remote control device (transmitter) together with a sequential control device main body and main operation (control). A control unit (control box) 79 provided with a panel and a battery 80 are installed, and a start button 82 and an emergency stop button 83 for manual operation are provided at the upper end of the vertical frame 18 on the rear side of the machine frame 16. An auxiliary operation panel 81 having the above is attached.

図示の形態は大略上記のような構成で、遠隔操作器又は補助操作盤81の起動ボタン82からの起動操作信号に基づいて、前後の各車輪21を各電動モータ24により正転駆動して、架空送電線10に沿って前進させ、ダンパー検出センサー27によるねじれ防止ダンパー11の二連重り12の前端の検出信号により、各電動モータ24の駆動を停止して、ねじれ防止ダンパー11に対する位置決めをした後、次の制御信号に基づいて、ダンパー取外し装置30の円筒昇降柱34の電動手段である昇降ねじ軸43を、電動モータ45の初期の所定の駆動を介して規定量正転して、円筒昇降柱34を、図2の状態から昇降の中間域を所定の高さ上昇することにより、ねじれ防止ダンパー11を、重り受皿37によって二連重り12を支持しながら所定高さ持上げて、図1に示すように、ねじれ防止ダンパー11、従って押えボルト14をボルト取外し装置50のボックスレンチ62に対して位置決めにする。   The illustrated form is generally configured as described above, and the front and rear wheels 21 are driven forward by the electric motors 24 based on the start operation signal from the start button 82 of the remote controller or the auxiliary operation panel 81. The electric motor 24 is moved forward along the overhead power transmission line 10, and the driving of each electric motor 24 is stopped by the detection signal at the front end of the double weight 12 of the torsion prevention damper 11 by the damper detection sensor 27, and positioning with respect to the torsion prevention damper 11 is performed. Thereafter, on the basis of the next control signal, the lifting screw shaft 43, which is the electric means of the cylindrical lifting column 34 of the damper removing device 30, is rotated forward by a predetermined amount via the initial predetermined drive of the electric motor 45, and the cylindrical The lifting column 34 is lifted from the state shown in FIG. 2 by a predetermined height in the middle region of lifting, so that the torsion prevention damper 11 is supported by the weight receiving tray 37 and the double weight 12 is supported. Lift predetermined height, as shown in FIG. 1, the anti-twist damper 11, thus the positioning of the pressing bolt 14 against lug wrench 62 of the bolt removal device 50.

次いで、ボルト取外し装置50のレンチ進退台55の電動手段を構成する進退ねじ軸58を電動モータ59からチェーン機構60を介して正転して、レンチ進退台55を待機位置からねじれ防止ダンパー11に向かって前進し、レンチ前進検出センサー74の検出信号に基づいて停止する。この間にレンチボックス掛止めレバー69の後端部69aのレバー揺動ガイド73のレバー後端部追従ガイドエッジの73bから73aへの係合を介して、レンチボックス掛止めフック71の前傾揺動力のままにその下端がレンチボックス65の上部の外周面部に当接する一方、最前進時には電動式ボックスレンチ62の先端のレンチボックス65の押えボルト14の頭部に対する嵌合による後方への押圧により、レンチボックス65付きレンチシャンク64がばね66に抗した収縮を介して後退し、この結果レンチボックス掛止めレバー69のレンチボックス掛止めフック70が、その内角近傍部がレンチボックス65の最上部の外周面部に当接する状態(図5仮想線参照)において、レンチボックス65の直前部に押えボルト14の頭部(及びワッシャー15)を挟むように下降し、レンチボックス65付きレンチシャンク64を収縮位置に保持する。この後ボックスレンチ62の作動により、レンチ軸63及びレンチボックス65付きレンチシャンク64が回転し、押えボルト14を緩めるとともに、電動モータ59の逆転駆動により進退ねじ軸58が逆転して、レンチ進退台55が後退し、押えボルト14をワッシャー15付きの状態でダンパー本体の送電線クランプ13のねじ穴から引き抜く。 Next, the forward / backward screw shaft 58 constituting the electric means of the wrench advance / retreat base 55 of the bolt removing device 50 is rotated forward from the electric motor 59 via the chain mechanism 60 to move the wrench advance / retreat base 55 from the standby position to the twist preventing damper 11. It moves forward and stops based on the detection signal of the wrench advance detection sensor 74. During this time, the forward tilting swinging force of the wrench box retaining hook 71 is established through the engagement of the lever trailing end tracking guide edge 73b to 73a of the lever swinging guide 73 of the rear end 69a of the wrench box retaining lever 69. While the lower end of the wrench box 65 is in contact with the outer peripheral surface portion of the wrench box 65 at the most forward position, the tip of the electric box wrench 62 is pressed backward by fitting with the head of the wrench box 65 of the wrench box 65 , The wrench shank 64 with the wrench box 65 is retracted through contraction against the spring 66. As a result, the wrench box latching hook 70 of the wrench box latching lever 69 has an inner corner near the outer periphery of the uppermost part of the wrench box 65. in contact with the state (see FIG. 5 phantom) to face the head of the holding bolts 14 immediately before end of the wrench box 65 And lowered to sandwich the washer 15) that holds the wrench shank 64 with wrenches box 65 in the retracted position. Thereafter, the wrench shaft 63 and the wrench shank 64 with the wrench box 65 are rotated by the operation of the box wrench 62, the presser bolt 14 is loosened, and the forward / backward screw shaft 58 is reversely rotated by the reverse drive of the electric motor 59. 55 is retracted, and the presser bolt 14 is pulled out from the screw hole of the transmission line clamp 13 of the damper body with the washer 15 attached.

レンチ進退台55が待機位置まで後退する間には、レンチボックス掛止めレバー69の後端部69aのレバー揺動ガイド73のレバー後端部追従ガイドエッジの前部の73a及びここから後部の73bへの係合を介して、レンチボックス掛止めフック70がレンチボックス65の直前部から跳ね上がり、収縮状態のレンチボックス65付きレンチシャンク64のばね66の作用力による瞬時の伸長を介して、レンチボックス65が瞬時に前進して復動するので、レンチボックス65から押えボルト14の頭部が離脱する。この結果ワッシャー15を伴っている押えボルト14は自重によりガイドシュート78からガイドシュート77を通してダンパー受容器76内に落下する。 While the wrench advancement / retreat base 55 is retracted to the standby position, the front 73a of the lever rear end tracking guide edge of the lever swing guide 73 of the rear end 69a of the wrench box latching lever 69, and the rear 73b of the rear end follower guide edge. Through the engagement with the wrench box, the wrench box latching hook 70 jumps up from the front part of the wrench box 65, and through the instantaneous extension by the action force of the spring 66 of the wrench shank 64 with the wrench box 65 in the contracted state , the wrench box 65 immediately advances and moves backward , so that the head of the presser bolt 14 is detached from the wrench box 65. As a result, the presser bolt 14 with the washer 15 falls from the guide chute 78 through the guide chute 77 into the damper receiver 76 by its own weight.

レンチ進退台55が所定の位置まで後退すると、レンチ後退検出センサー75の検出信号に基づいて、後退が停止する。この後ダンパー取外し装置30の円筒昇降柱34の電動手段の電動モータ45の正転駆動により、昇降ねじ軸43が正転して、円筒昇降柱34、従って重り受皿37が図1に示す状態から昇降の上部域直前までを真直ぐに上昇した後、昇降の上部域を略90°回転しながら上昇する。これによって重り受皿37上のダンパー本体は送電線クランプ13が架空送電線10から外れる状態まで真直ぐに上昇した後、送電線クランプ13が架空送電線10から離脱する。   When the wrench advance / retreat base 55 moves backward to a predetermined position, the backward movement stops based on the detection signal of the wrench reverse detection sensor 75. Thereafter, by the forward rotation of the electric motor 45 of the electric means of the cylindrical elevating column 34 of the damper removing device 30, the elevating screw shaft 43 is rotated forward, and the cylindrical elevating column 34, and thus the weight receiving tray 37 is moved from the state shown in FIG. After ascending straight up to just before the upper region of the ascending / descending, it ascends while rotating the upper region of the ascending / descending approximately 90 °. As a result, the damper main body on the weight receiving tray 37 rises straight until the power transmission line clamp 13 is detached from the overhead power transmission line 10, and then the power transmission line clamp 13 is detached from the overhead power transmission line 10.

この後電動モータ45の逆転駆動に基づいて、昇降ねじ軸43が逆転し、円筒昇降柱34が重り受皿37及びその上のダンパー本体とともに、昇降の上部域を逆回転しながら下降した後、昇降の中間域を真直ぐに下降する。この下降が昇降の下部域に入ると、直ちに重り受皿37は後端部が受皿ストッパー41に当接して、前下がりに傾斜し(図3参照)、これによりダンパー本体は二連重り12を介して前方に滑り落ちて、ガイドシュート77を通してダンパー受容器76内に受容され、一つのねじれ防止ダンパー11の取外しが完了する。   Thereafter, based on the reverse drive of the electric motor 45, the elevating screw shaft 43 is reversed, and the cylindrical elevating column 34 is lowered together with the weight receiving tray 37 and the damper body on the upper elevating area while rotating in the reverse direction. It goes down straight in the middle area. As soon as this descent enters the lower area of the lift, the weight receiving tray 37 comes into contact with the receiving stopper 41 at the rear end and tilts forward downward (see FIG. 3), so that the damper body passes through the double weight 12. Then, it slides forward and is received in the damper receiver 76 through the guide chute 77, and the removal of one of the twist preventing dampers 11 is completed.
