Description

本発明は、バッテリを動力源として駆動装置で走行し、車体後端部の牽引装置で被牽引車を連結して牽引するバッテリ式トーイングトラクタに関する。   The present invention relates to a battery type towing tractor that travels with a drive device using a battery as a power source and that is towed by connecting a towed vehicle with a traction device at a rear end of a vehicle body.

バッテリ式トーイングトラクタは、バッテリを動力源として駆動装置で走行し、車体後端部の牽引装置で台車やトレーラー等の被牽引車を連結して牽引する(例えば、特許文献1及び2参照)。バッテリ式トーイングトラクタは、走行操作するためのアクセル手段と、停止操作するためのブレーキ手段とを備える。そして、バッテリ式トーイングトラクタは、アクセル手段の操作量に応じて前後進速度が変位して、アクセル手段の操作がなければ走行しないようになっている。   A battery type towing tractor travels with a drive device using a battery as a power source, and tows a towed vehicle such as a carriage or a trailer with a towing device at the rear end of the vehicle body (see, for example, Patent Documents 1 and 2). The battery-type towing tractor includes an accelerator means for running and a brake means for stopping. The battery type towing tractor is configured such that the forward / backward moving speed is displaced according to the operation amount of the accelerator means, and does not travel unless the accelerator means is operated.

そのため、運転者は、車体後端部に設けられた牽引装置に被牽引車を連結する際に、後を見ながら、アクセル手段を操作して微速走行させながら、ブレーキ手段で停止させているため、連結可能な位置に移動・停止させるまで、アクセル手段とブレーキ手段とを繰り返し操作しなければならず、連結作業が非常に困難であった。

バッテリを動力源として駆動装置で走行し、車体後端部に設けられた牽引装置で被牽引車を連結して牽引するバッテリ式トーイングトラクタにおいて、
牽引装置に設けられた連結手段と、連結手段の連結及び解除を検知する検知手段と、走行操作するためのアクセル手段と、停止操作するためのブレーキ手段と、駆動装置を制御する制御手段とを備え、
制御手段は、
検知手段が連結手段の連結を検知する際、アクセル手段の操作がなければ走行しないようにし、
検知手段が連結手段の解除を検知する際、アクセル手段の操作がなくても微速走行させる。
The battery type towing tractor according to the present invention is
In a battery type towing tractor that travels with a driving device using a battery as a power source and connects and pulls the towed vehicle with a towing device provided at the rear end of the vehicle body,
A connecting means provided in the traction device; a detecting means for detecting connection and release of the connecting means; an accelerator means for operating the vehicle; a brake means for stopping the operation; and a control means for controlling the driving device. Prepared,
The control means
When the detecting means detects the connection of the connecting means, it will not run unless the accelerator means is operated,
When the detecting means detects the release of the connecting means, it travels at a slow speed even if the accelerator means is not operated.

好ましくは、
連結手段は、被牽引車を連結及び解除するためのドローバーピンと、ドローバーピンを操作するための操作レバーとを備え、
検知手段は、操作レバーの操作に基づいて、ドローバーピンの連結及び解除を検知するスイッチ手段を備える。
Preferably,
The connecting means includes a draw bar pin for connecting and releasing the towed vehicle, and an operation lever for operating the draw bar pin,
The detection means includes switch means for detecting connection and release of the draw bar pin based on the operation of the operation lever.

本発明に係るバッテリ式トーイングトラクタは、検知手段が連結手段の連結を検知する際、アクセル手段の操作がなければ走行しない。そのため、被牽引車を牽引する通常の走行時においては、運転者は従来通りにアクセル手段を操作して走行させる。
そして、本発明では、検知手段が連結手段の解除を検知する際、即ち、牽引装置に被牽引車を連結する際には、アクセル手段の操作がなくても微速走行するようになっている。そのため、アクセル手段を操作しなくても、微速走行で前後進して被牽引車に近づけたり離したりして、ブレーキ手段の操作だけで連結位置に停止させることができる。従って、運転者は、アクセル手段を操作せずに、ブレーキ手段の操作のみで所定の連結位置まで移動・停止できるので、連結作業を非常にスムーズに行うことができる。
The battery type towing tractor according to the present invention does not travel unless the accelerator means is operated when the detecting means detects the connection of the connecting means. Therefore, at the time of normal traveling for towing the towed vehicle, the driver operates the accelerator means as usual to travel.
In the present invention, when the detecting means detects the release of the connecting means, that is, when the towed vehicle is connected to the towing device, the vehicle travels at a low speed even if the accelerator means is not operated. Therefore, even if the accelerator means is not operated, the vehicle can be moved forward and backward at a slow speed to approach or separate from the towed vehicle, and can be stopped at the connected position only by operating the brake means. Therefore, the driver can move and stop to a predetermined connection position only by operating the brake means without operating the accelerator means, and the connection work can be performed very smoothly.

図2の通り、牽引装置1は、ドローバーピン11を備える。ドローバーピン11は、車体後端部30aに設けたドローバーブラケット14を介して、上下方向に昇降可能になっている。牽引装置1は、車体後端部30aに立設された支柱12を備える。支柱12は、軸12aを備えており、この軸12aには、ドローバーピン11に連結されたリンク部材13の基端部が軸支される。さらに、リンク部材13の基端部には、操作レバー10が連結されており、操作レバー10の操作によって、軸12aを中心にリンク部材13が回転して、ドローバーピン11を昇降動作するようになっている。   As shown in FIG. 2, the traction device 1 includes a draw bar pin 11. The drawbar pin 11 can be moved up and down through a drawbar bracket 14 provided at the rear end 30a of the vehicle body. The traction device 1 includes a support 12 that is erected on the rear end 30a of the vehicle body. The column 12 includes a shaft 12a, and a base end portion of the link member 13 connected to the draw bar pin 11 is pivotally supported on the shaft 12a. Further, an operation lever 10 is connected to the base end portion of the link member 13, and the link member 13 rotates about the shaft 12 a by the operation of the operation lever 10 so that the draw bar pin 11 is moved up and down. It has become.

牽引装置1は、被牽引車の連結バー4を連結及び解除する。連結バー4は、挿通孔4aが穿設されており、この挿通孔4aにドローバーピン1を挿脱することで、被牽引車の連結バー4を連結・解除するようになっている。図2(A−1)の通り、操作レバー10を図左側に倒すことで、ドローバーピン11を上げて、被牽引車の連結バー4からドローバーピン11を外して、解除状態にする。そして、図2(B−1)の通り、操作レバー10を図右側に倒すことで、ドローバーピン11を下げて、被牽引車の連結バー4にドローバーピン11を挿入して、連結状態にする。   The traction device 1 connects and releases the connecting bar 4 of the towed vehicle. The connecting bar 4 is provided with an insertion hole 4a, and the draw bar pin 1 is inserted into and removed from the insertion hole 4a so that the connection bar 4 of the towed vehicle is connected and released. As shown in FIG. 2A-1, the draw bar pin 11 is raised by tilting the operation lever 10 to the left side in the drawing, and the draw bar pin 11 is removed from the connecting bar 4 of the towed vehicle to be in the released state. Then, as shown in FIG. 2 (B-1), the draw bar pin 11 is lowered by tilting the operating lever 10 to the right side of the figure, and the draw bar pin 11 is inserted into the connecting bar 4 of the towed vehicle to establish a connected state. .

図2(A−2)及び(B−2)の通り、牽引装置1は、支柱12に設けられたスイッチ手段5を備える。スイッチ手段5は、操作レバー10の操作に応じて、オン・オフするようになっており、オン・オフ信号を制御部2へ送信する。制御部2は、このオン・オフ信号に基づいて、後述するように、駆動装置21による走行を制御する。   As shown in FIGS. 2 (A-2) and 2 (B-2), the traction device 1 includes switch means 5 provided on the support column 12. The switch means 5 is turned on / off according to the operation of the operation lever 10 and transmits an on / off signal to the control unit 2. Based on the on / off signal, the control unit 2 controls traveling by the drive device 21 as described later.

図2(A−1)及び(A−2)の通り、操作レバー10を図左側に倒して、解除状態にすると、スイッチ手段5がオン信号(解除信号)を制御部2へ送信する。そして、図2(B−1)及び(B−2)の通り、操作レバー10を図右側に倒して、連結状態にすると、スイッチ手段5がオフ信号(連結信号)を制御部2へ送信する。   As shown in FIGS. 2A-1 and 2A-2, when the operation lever 10 is tilted to the left side in the drawing and released, the switch means 5 transmits an ON signal (release signal) to the control unit 2. Then, as shown in FIGS. 2B-1 and 2B-2, when the operation lever 10 is tilted to the right side in the drawing to be connected, the switch means 5 transmits an off signal (connection signal) to the control unit 2. .

制御部2は、スイッチ手段5からオン信号(解除信号)が送信されると第1走行モードとし、スイッチ手段5からオフ信号(連結信号)が送信されると第2走行モードとするようになっている。   When the on signal (release signal) is transmitted from the switch unit 5, the control unit 2 enters the first travel mode, and when the off signal (connection signal) is transmitted from the switch unit 5, the control unit 2 enters the second travel mode. ing.

第1走行モードでは、制御部2は、アクセル手段33の操作がなくても、駆動装置21が駆動して、バッテリ式トーイングトラクタが微速走行するようになっている。そして、第2走行モードでは、制御部2は、アクセル手段33を操作することで、駆動装置21が駆動して走行するようになっており、アクセル手段33の操作がなければ、バッテリ式トーイングトラクタが走行しないようになっている。   In the first traveling mode, the controller 2 is configured such that the driving device 21 is driven and the battery type towing tractor travels at a low speed even when the accelerator means 33 is not operated. In the second traveling mode, the control unit 2 operates the accelerator unit 33 to drive the drive unit 21. If the accelerator unit 33 is not operated, the battery type towing tractor is operated. Is not going to run.

上記の通り、被牽引車を連結した状態(図2(B−1))においては、アクセル手段33の操作がなければ走行しないので、運転者は従来通りにアクセル手段33を操作して走行する。そして、被牽引車を解除した状態(図2(A−1))においては、アクセル手段33の操作がなくても駆動装置21で微速走行する。そのため、アクセル手段33を操作しなくても、微速走行(微速前後進)によって被牽引車へ牽引装置1を近づけたり離したりして、ブレーキ手段34の操作で連結位置に停止させる。従って、運転者は、アクセル手段33を操作する必要がなく、ブレーキ手段34の操作のみで所定の連結位置まで移動・停止できるので、連結作業を非常にスムーズに行うことができる。   As described above, in the state where the towed vehicle is connected (FIG. 2 (B-1)), since the vehicle does not travel without the operation of the accelerator means 33, the driver travels by operating the accelerator means 33 as usual. . And in the state (FIG. 2 (A-1)) which the towed vehicle was cancelled | released, even if there is no operation of the accelerator means 33, it drive | works at low speed with the drive device 21. FIG. For this reason, even if the accelerator means 33 is not operated, the traction device 1 is moved closer to or away from the towed vehicle by slow speed travel (slow forward and backward travel), and is stopped at the connected position by operating the brake means 34. Therefore, the driver does not need to operate the accelerator means 33 and can move and stop to a predetermined connecting position only by operating the brake means 34, so that the connecting work can be performed very smoothly.

なお、上記実施形態では、スイッチ手段5が、被牽引車の連結・解除を検知するが、位置センサー等で、ドローバーピン11等の有無を検知して、被牽引車の連結・解除を検知してもよい。   In the above embodiment, the switch means 5 detects the connection / release of the towed vehicle. However, the position sensor or the like detects the presence / absence of the draw bar pin 11 or the like to detect the connection / release of the towed vehicle. May be.
