従来、新幹線用の保守用車は、モーターカーのスイッチ操作によって、電気接続された被牽引のトロッコの電磁弁ブレーキを作動させて空気ブレーキを掛けるように制御される。モーターカーとトロッコが切り離された場合には、トロッコの電磁弁ブレーキと減圧弁ブレーキの両方が自動的に作動し、トロッコに留置ブレーキが掛かるように構成されている。
しかし、トロッコを移動させる際に留置ブレーキを解除する必要が生じると、電磁弁と減圧弁に接続されている空気タンクの圧縮空気を、大気開放することにより減圧して制動を解除するため、再度留置ブレーキを掛けることができなくなる欠点があります。
また、トロッコに、圧縮空気がなくても作動する手動式のハンドルブレーキを併設したものも提案されているが、このハンドルブレーキは、作業員が意識して掛けない限り作動しないため、掛け忘れや操作ミス等で事故が発生する虞れがあった。 Conventionally, a Shinkansen maintenance vehicle is controlled to apply an air brake by actuating a solenoid valve brake of a towed trolley that is electrically connected by operating a switch of a motor car. When the motor car and the truck are separated, both the electromagnetic valve brake and the pressure reducing valve brake of the truck are automatically operated, and the indwelling brake is applied to the truck.
However, when it is necessary to release the indwelling brake when moving the truck, the compressed air in the air tank connected to the solenoid valve and the pressure reducing valve is decompressed by releasing it to the atmosphere to release the braking. There is a drawback that the indwelling brake cannot be applied.
In addition, a trolley truck with a manual handle brake that operates even when there is no compressed air has been proposed, but this handle brake does not operate unless the operator applies it consciously. There was a risk of accidents due to operational mistakes.

そこで、本発明は、モーターカーとの連結が切り離された状態で、自動的に駐車ブレーキがかかり、必要に応じて、軌道上を小移動させることができる保守用トロッコを提供することを目的とする。   Accordingly, an object of the present invention is to provide a maintenance truck that can automatically be parked in a state where the connection with the motor car is disconnected and can be moved small on the track as necessary. To do.

本発明に係る保守用トロッコは、モーターカーに連結されて軌道を走行する保守用トロッコに於て、上記連結が切断された分離状態下で、機械的ブレーキ機構を自動的に作動させる駐車ブレーキ用弾発部材を設け、手動レバーの一方向への揺動によって上記弾発部材の弾発付勢力に抗して上記機械的ブレーキ機構の制動作用を解除可能な手動解除手段を具備しているものである。   A maintenance truck according to the present invention is a maintenance truck that is connected to a motor car and travels on a track, for a parking brake that automatically operates a mechanical brake mechanism in a separated state in which the connection is disconnected. Provided with a bullet release member and provided with manual release means capable of releasing the braking action of the mechanical brake mechanism against the bullet urging force of the bullet member by swinging the manual lever in one direction It is.

また、上記手動解除手段は、上記弾発部材の弾発付勢力を利用した上記機械的ブレーキ機構の制動作用を、上記手動レバーの逆方向への揺動によって復元可能に構成されているものである。   Further, the manual release means is configured to be able to restore the braking action of the mechanical brake mechanism using the elastic biasing force of the elastic member by swinging the manual lever in the reverse direction. is there.

本発明の保守用トロッコによれば、空気タンク内に圧縮空気が無くても、機械的な駐車ブレーキを自動的に作動させることが可能となり、安全性が高い。また、必要に応じて、機械的ブレーキ機構による駐車ブレーキを手動で容易に解除できるため軌道上を簡単に移動させることができる。   According to the maintenance truck of the present invention, even if there is no compressed air in the air tank, the mechanical parking brake can be automatically operated, and safety is high. Moreover, since the parking brake by a mechanical brake mechanism can be easily released manually as needed, it can be easily moved on the track.

図１〜図４に示すように、本発明の保守用トロッコＴは、先導するモーターカーＭの駆動力によって軌道を走行する新幹線用保守用車を構成するものである。保守用トロッコＴは、モーターカーＭとの連結が切断された分離状態下で、機械的ブレーキ機構２を自動的に作動させる駐車ブレーキ用弾発部材２０を設けている。また、トロッコＴは、手動レバー１０の一方向Ａへの揺動によって弾発部材２０の弾発付勢力Ｆに抗して機械的ブレーキ機構２の制動作用を解除可能な手動解除手段１を具備している。手動解除手段１は、弾発部材２０の弾発付勢力Ｆを利用した機械的ブレーキ機構２の制動作用を、手動レバー１０の逆方向Ｂへの揺動によって復元可能に構成している。 Hereinafter, the present invention will be described in detail with reference to the drawings illustrating embodiments.
As shown in FIGS. 1 to 4, the maintenance truck T of the present invention constitutes a Shinkansen maintenance vehicle that travels on a track by the driving force of a leading motor car M. The maintenance truck T is provided with a parking brake resilient member 20 that automatically operates the mechanical brake mechanism 2 in a separated state in which the connection with the motor car M is disconnected. Further, the trolley T includes manual release means 1 that can release the braking action of the mechanical brake mechanism 2 against the bullet urging force F of the bullet member 20 by swinging the manual lever 10 in one direction A. is doing.

保守用トロッコＴは、４つの車輪４…を有し、モーターカーＭに牽引されて軌道上を走行可能である。保守用トロッコＴは、制動装置として、機械的ブレーキ機構２と空圧的ブレーキ機構３を備えている。保守用トロッコＴは、前後にカプラ１１を接続可能な元圧管１２及び貫通制動管１６と、複数の分岐管１３と、を有するエア配管６を備えている。エア配管６は、圧縮空気の圧力を利用してピストンを往復運動させるアクチュエータから成る往復気筒部材５と、ドレンコック３６を有し圧縮空気を備蓄可能なエアタンク３２を繋ぐように配管している。往復気筒部材５は、機械的ブレーキ機構２を操作するためのリターンシリンダ２５と、空圧的ブレーキ機構３を操作するためのブレーキシリンダ３５とから成り、リターンシリンダ２５とブレーキシリンダ３５を直列に連結している。なお、貫通制動管１６は、前後のトロッコＴに従来の減圧弁ブレーキが設けてある場合に備えて、単なる引き通しとして設けられていてもよい。   The maintenance truck T has four wheels 4... And is pulled by the motor car M and can travel on the track. The maintenance truck T includes a mechanical brake mechanism 2 and a pneumatic brake mechanism 3 as braking devices. The maintenance truck T includes an air pipe 6 having a main pressure pipe 12 and a through brake pipe 16 to which a coupler 11 can be connected before and after, and a plurality of branch pipes 13. The air pipe 6 is connected so as to connect the reciprocating cylinder member 5 composed of an actuator for reciprocating the piston using the pressure of compressed air and the air tank 32 having a drain cock 36 and capable of storing compressed air. The reciprocating cylinder member 5 includes a return cylinder 25 for operating the mechanical brake mechanism 2 and a brake cylinder 35 for operating the pneumatic brake mechanism 3, and the return cylinder 25 and the brake cylinder 35 are connected in series. is doing. Note that the through brake pipe 16 may be provided as a simple pull-in in case a conventional pressure reducing valve brake is provided in the front and rear trucks T.

手動解除手段１は、枢着部材１５に枢着された差込部材１７に着脱自在に差込まれると共に、揺動軸心Ｌ１廻りに揺動自在の手動レバー１０を有している。手動解除手段１は、手動レバー１０の揺動に連動して枢着部材１５の揺動軸心Ｌ１方向奥側に取付けられた揺動片７を揺動させ、揺動片７にロッドエンド（自在継手）を介して取り付けた可動部材１４を水平方向に移動させるように構成している。可動部材１４は、機械的ブレーキ機構２の一部に連結されている。
図４に於て、手動解除手段１は、手動レバー１０をブレーキ解除方向（図中矢印Ａ方向）へ揺動操作して、機械的ブレーキ機構２による制動作用を解除可能であり、かつ、手動レバー１０をブレーキ復元方向（図中矢印Ｂ方向）に揺動操作すると再び機械的ブレーキ機構２の制動作用を効かせるように構成している。
なお、図１に示すように、トロッコＴがモーターカーＭに連結されて走行している際は、（図２に二点鎖線をもって示した）手動レバー１０は取り外されている。 Manual release means 1 freely with the plugged removably in the insertion member 17 which is pivotally secured to the pivoted member 15, and a manual lever 10 in swingable pivot axis L 1 around. Manual release means 1, to oscillate the oscillation axis L 1 swinging piece 7 mounted in the direction rear side of the pivot member 15 in conjunction with the swinging of the manual lever 10, the rod end to the swing piece 7 The movable member 14 attached via (universal joint) is configured to move in the horizontal direction. The movable member 14 is connected to a part of the mechanical brake mechanism 2.
In FIG. 4, the manual release means 1 can release the braking action by the mechanical brake mechanism 2 by swinging the manual lever 10 in the brake release direction (arrow A direction in the figure), and manually. When the lever 10 is swung in the brake restoring direction (the direction of arrow B in the figure), the braking action of the mechanical brake mechanism 2 is applied again.
As shown in FIG. 1, when the truck T is traveling while being connected to the motor car M, the manual lever 10 (shown by a two-dot chain line in FIG. 2) is removed.

具体的には、機械的ブレーキ機構２は、第１制動軸心Ｌ２廻りに揺動自在のアーム２１を備えている。機械的ブレーキ機構２は、アーム２１の揺動に対応して動くブレーキシュー９…を車輪４…に押し付けて回転を拘束することでトロッコＴを制動するように構成されている。また、アーム２１には、駐車ブレーキ用弾発部材２０と、リターンシリンダ２５のロッドと、が枢着されている。駐車ブレーキ用弾発部材２０は、常時伸長する方向（図中矢印方向）に弾発付勢力Ｆを作用している。機械的ブレーキ機構２は、ブレーキ用弾発部材２０によって、保守用トロッコＴに制動力を作用させるようにアーム２１を弾発付勢している。図２に於て、リターンシリンダ２５は、エアタンク３２内の圧縮空気を利用してロッドを縮退させ、駐車ブレーキ用弾発部材２０の弾発付勢力Ｆに抗して、機械的ブレーキ機構２の制動作用を解除している状態を図示している。なお、図３に於て、弾発部材２０は、省スペースでダンパー機能を有する一対のガススプリングから成るものを例示しているが、機械的なコイルスプリングを用いるもよく、また、リターンシリンダ２５の内部にロッドと同心状になるように配設するも好ましい。 Specifically, the mechanical brake mechanism 2 is provided with a pivotable arm 21 to the first brake axis L 2 around. The mechanical brake mechanism 2 is configured to brake the trolley T by pressing the brake shoes 9 that move in response to the swing of the arm 21 against the wheels 4 to restrain the rotation. The arm 21 is pivotally mounted with a parking brake resilient member 20 and a rod of a return cylinder 25. The parking brake elastic member 20 applies an elastic biasing force F in a direction in which the parking brake elastic member 20 always extends (the arrow direction in the figure). In the mechanical brake mechanism 2, the arm 21 is elastically biased by the brake elastic member 20 so as to apply a braking force to the maintenance truck T. In FIG. 2, the return cylinder 25 uses the compressed air in the air tank 32 to retract the rod, and against the elastic urging force F of the parking brake elastic member 20, A state in which the braking action is released is illustrated. In FIG. 3, the elastic member 20 is exemplified by a pair of gas springs having a space-saving and damper function. However, a mechanical coil spring may be used, and the return cylinder 25 may be used. It is also preferable to arrange it so as to be concentric with the rod.

図５に示すように、リターンシリンダ２５の空気圧が開放されると、弾発部材２０の弾発付勢力Ｆにより自動的に機械的ブレーキ機構２が作動するように構成されている。手動解除手段１は、可動部材１４をアーム２１の一端２３にロッドエンド（自在継手）を介して連結しており、手動レバー１０を取付けて操作することで、弾発部材２０の弾発付勢力Ｆに抗してアーム２１を強制的に揺動させ、機械的ブレーキ機構２の制動作用を解除させるように構成している。   As shown in FIG. 5, when the air pressure of the return cylinder 25 is released, the mechanical brake mechanism 2 is automatically operated by the elastic urging force F of the elastic member 20. The manual release means 1 connects the movable member 14 to one end 23 of the arm 21 via a rod end (universal joint), and is operated by attaching the manual lever 10 so that the elastic biasing force of the elastic member 20 is obtained. The arm 21 is forcibly swung against F to release the braking action of the mechanical brake mechanism 2.

図１及び図６に示すように、空圧的ブレーキ機構３は、ブレーキシリンダ３５にてアーム３１を第２制動軸心Ｌ３廻りに揺動操作し、ブレーキシュー９…を動かして車輪４…の回転を拘束することでトロッコＴを制動するように構成されている。ブレーキシリンダ３５は、電磁弁ユニット３０のスイッチ操作によってエアタンク３２内の圧縮空気を利用して作動し、ブレーキシリンダ３５に供給する空気圧を電気的に制御することで保守用トロッコＴの車輪４…に付与する制動力を調整している。なお、空圧的ブレーキ機構３のアーム３１は、機械的ブレーキ機構２のアーム２１に連結杆８及び引っ張りバネ３４にて連結され、ブレーキシリンダ３５が減圧した状態では、ブレーキを解除するように弾発付勢されている。 As shown in FIGS. 1 and 6, pneumatic brake mechanism 3, the arm 31 in the brake cylinder 35 pivoted to the second brake axis L 3 around the wheels 4 to move the brake shoe 9 ... ... The trolley T is braked by restricting the rotation of the trolley. The brake cylinder 35 is operated by using the compressed air in the air tank 32 by a switch operation of the electromagnetic valve unit 30 and electrically controls the air pressure supplied to the brake cylinder 35 to thereby turn the wheels 4 of the maintenance trolley T. The braking force to be applied is adjusted. The arm 31 of the pneumatic brake mechanism 3 is connected to the arm 21 of the mechanical brake mechanism 2 by the connecting rod 8 and the tension spring 34, and when the brake cylinder 35 is depressurized, the arm 31 is released to release the brake. It is energized.

上述した本発明の保守用トロッコの使用方法（作用）について説明する。
図１に於て、保守用トロッコＴがモーターカーＭに連結されて走行している状態を示している。モーターカーＭは、連結器を介して保守用トロッコＴ…を牽引し、モーターカーＭの制御部と保守用トロッコＴの電磁弁ユニット３０とを電気回線にて電気的に接続すると共に、モーターカーＭのコンプレッサによって加圧した圧縮空気をカプラ１１を介して元圧管１２に供給している。機械的ブレーキ機構２は、エアタンク３２内の圧縮空気を利用して制動作用を解除し、かつ、空圧的ブレーキ機構３は、モーターカーＭの制御部からの電気信号により制動作用を適宜コントロールされる。 The use method (action) of the above-described maintenance truck of the present invention will be described.
FIG. 1 shows a state where the maintenance truck T is connected to the motor car M and is running. The motor car M pulls the maintenance trolley T through a coupler, electrically connects the control unit of the motor car M and the electromagnetic valve unit 30 of the maintenance trolley T with an electric circuit, and also the motor car. Compressed air pressurized by the M compressor is supplied to the main pressure pipe 12 through the coupler 11. The mechanical brake mechanism 2 releases the braking action by using the compressed air in the air tank 32, and the pneumatic braking mechanism 3 is appropriately controlled by the electric signal from the control unit of the motor car M. The

保守用トロッコＴとモーターカーＭの連結が切断され、電気的接続が切断されたことを検知すると、空圧的ブレーキ機構３は、エアタンク３２内の圧縮空気を利用してブレーキシリンダ３５を作動させ、トロッコＴに駐車ブレーキを効かせる（図６参照）。この際、電磁弁ユニット３０は、エアタンク３２内の圧縮空気が開放されないようにエア配管６を適宜遮断して、リターンシリンダ２５の空気圧を保持する。
次に、保守用トロッコＴを軌道上で小移動させる際には、ドレンコック３６を開放し、エアタンク３２内の圧縮空気を大気開放する。この際、ブレーキシリンダ３５の空気が開放され空圧的ブレーキ機構３による制動が解除されると共に、リターンシリンダ２５の空気が開放され機械的ブレーキ機構２が弾発部材２０の弾発付勢力Ｆにより自動的に駐車ブレーキを効かせる（図５参照）。そして、手動レバー１０を取付けて揺動操作を行なって、機械的ブレーキ機構２の制動作用を手動解除する（図２参照）。このようにして、保守用トロッコＴの駐車ブレーキを解除し、走行可能として、手押しで（人力にて）軌道上を移動させる。 When it is detected that the maintenance truck T and the motor car M are disconnected and the electrical connection is disconnected, the pneumatic brake mechanism 3 operates the brake cylinder 35 using the compressed air in the air tank 32. The parking brake is applied to the truck T (see FIG. 6). At this time, the solenoid valve unit 30 appropriately shuts off the air pipe 6 so that the compressed air in the air tank 32 is not released, and maintains the air pressure of the return cylinder 25.
Next, when the maintenance truck T is moved on the track, the drain cock 36 is opened, and the compressed air in the air tank 32 is released to the atmosphere. At this time, the air in the brake cylinder 35 is released and the braking by the pneumatic brake mechanism 3 is released, and the air in the return cylinder 25 is released and the mechanical brake mechanism 2 is operated by the elastic urging force F of the elastic member 20. The parking brake is automatically applied (see FIG. 5). Then, the manual lever 10 is attached and a swing operation is performed to manually release the braking action of the mechanical brake mechanism 2 (see FIG. 2). In this way, the parking brake of the maintenance truck T is released, and the vehicle can be moved and moved on the track by hand (by human power).

その後、手動解除手段１によって機械的ブレーキ機構２の制動作用を復元し、保守用トロッコＴを停留する。この際、手動解除手段１の手動レバー１０は、駐車ブレーキ用弾発部材２０の弾発付勢力Ｆにより逆方向Ｂへ揺動するように弾発付勢される。手動解除手段１の操作者は、レバー１０から手を離すと自動的に制動作用を復元し、ワンタッチで駐車ブレーキを効かせて保守用トロッコＴを停止させる。保守用トロッコＴは、駐車ブレーキ用弾発部材２０の弾発付勢力Ｆを利用して機械的ブレーキ機構２を作動させるため、小移動を行なうために駐車ブレーキの解除・復元を複数回繰り返しても制動力を失うことがなく、所望の場所にて確実に停止保持し安全な状態で留置が可能である。   Thereafter, the manual release means 1 restores the braking action of the mechanical brake mechanism 2 and stops the maintenance truck T. At this time, the manual lever 10 of the manual release means 1 is elastically urged to swing in the reverse direction B by the elastic urging force F of the parking brake elastic member 20. When the operator of the manual release means 1 releases the lever 10, the braking action is automatically restored, the parking brake is applied with one touch, and the maintenance truck T is stopped. The maintenance trolley T operates the mechanical brake mechanism 2 by using the elastic urging force F of the elastic member 20 for the parking brake, so that the parking brake is repeatedly released and restored several times for small movement. However, the braking force is not lost, and it is possible to stop and hold at a desired place and to place it in a safe state.

なお、本発明に於て、機械的ブレーキ機構２及び空圧的ブレーキ機構３は、トロッコＴの４つの車輪４，４，４，４に対して、均等に制動力を作用するように構成されている。従って、例えば、保守用トロッコＴに重量１５ｔの荷物や重機等を積載した場合であっても信頼性の高い駐車ブレーキを掛け、確実に逸走を防止する。   In the present invention, the mechanical brake mechanism 2 and the pneumatic brake mechanism 3 are configured to apply the braking force equally to the four wheels 4, 4, 4, 4 of the truck T. ing. Therefore, for example, even when a 15-ton load, heavy machinery, or the like is loaded on the maintenance truck T, a highly reliable parking brake is applied to reliably prevent a runaway.

以上のように、本発明は、モーターカーＭに連結されて軌道を走行する保守用トロッコに於て、連結が切断された分離状態下で、機械的ブレーキ機構２を自動的に作動させる駐車ブレーキ用弾発部材２０を設け、手動レバー１０の一方向Ａへの揺動によって弾発部材２０の弾発付勢力Ｆに抗して機械的ブレーキ機構２の制動作用を解除可能な手動解除手段１を具備しているので、エアタンク３２内に圧縮空気が無くても、弾発部材２０の弾発付勢力Ｆを利用した機械的な駐車ブレーキを自動的に作動させることができ、安全性が高い。また、必要に応じて、機械的ブレーキ機構２による駐車ブレーキを手動で容易に解除できるため軌道上を簡単に（人力にて）移動させることができる。   As described above, the present invention is a parking brake that automatically operates the mechanical brake mechanism 2 in the maintenance truck that is connected to the motor car M and travels on the track in a separated state in which the connection is disconnected. Manual release means 1 that is provided with an elastic member 20 and can release the braking action of the mechanical brake mechanism 2 against the elastic force F of the elastic member 20 by swinging the manual lever 10 in one direction A. Therefore, even if there is no compressed air in the air tank 32, the mechanical parking brake using the bullet urging force F of the bullet member 20 can be automatically operated, and the safety is high. . Moreover, since the parking brake by the mechanical brake mechanism 2 can be easily released manually as needed, it can be easily moved (by human power) on the track.

また、手動解除手段１は、弾発部材２０の弾発付勢力Ｆを利用した機械的ブレーキ機構２の制動作用を、手動レバー１０の逆方向Ｂへの揺動によって復元可能に構成されているので、ワンタッチで機械的ブレーキ機構２による駐車ブレーキを復元させて確実に逸走を防止でき、軌道上に安全に留置できる。   Further, the manual release means 1 is configured to be able to restore the braking action of the mechanical brake mechanism 2 using the elastic urging force F of the elastic member 20 by swinging the manual lever 10 in the reverse direction B. Therefore, the parking brake by the mechanical brake mechanism 2 can be restored with one touch, and the escape can be surely prevented and can be safely placed on the track.
