Description

作業車両の車体構造Work vehicle body structure
　本発明は、作業車両の車体構造の技術に関する。 The present invention relates to a technique for a vehicle body structure of a work vehicle.
　従来より、空調装置のコンデンサをエンジンの近傍に配置した作業車両が知られている（例えば特許文献１参照）。これは、エンジンのファンによって発生する空気流をラジエータのみならずコンデンサにも送るためである。このような構造の作業車両では、空調装置のエバポレータ等とコンデンサを長く複雑な形状の配管で接続することとなるため、コストの増加や生産性の悪化という問題を生じる場合があった。 Conventionally, a work vehicle is known in which a condenser of an air conditioner is arranged in the vicinity of an engine (see, for example, Patent Document 1). This is because the air flow generated by the engine fan is sent not only to the radiator but also to the condenser. In the work vehicle having such a structure, the evaporator of the air conditioner and the capacitor are connected with a long and complicated pipe, which may cause a problem of increase in cost and deterioration in productivity.
　また、ダンパを用いてフロアパネルやキャビンを支持した作業車両が知られている（例えば特許文献２参照）。これは、例えばエンジンの運転によって発生する振動をオペレータに伝えないようにするためである。このような構造の作業車両では、キャビンの外部に配置されるコンデンサも別途のダンパによって支持することとなるため、コストの増加や生産性の悪化という問題を生じる場合があった。 Also, a work vehicle that supports a floor panel and a cabin using a damper is known (see, for example, Patent Document 2). This is because, for example, vibration generated by engine operation is not transmitted to the operator. In the work vehicle having such a structure, a capacitor disposed outside the cabin is also supported by a separate damper, which may cause a problem of an increase in cost and a decrease in productivity.
　更に、例えばコンデンサがキャビンに固定される構造においては、フロアパネルにキャビンを載置した後に配管等を接続していく組立作業が必要となる。このような構造の作業車両では、作業時間が長く作業手順も煩雑になるため、コストの増加や生産性の悪化という問題を生じる場合があった。 Furthermore, for example, in a structure in which the capacitor is fixed to the cabin, an assembly operation is required in which piping is connected after the cabin is placed on the floor panel. In the work vehicle having such a structure, the work time is long and the work procedure is complicated, which may cause a problem of an increase in cost and a decrease in productivity.

　本発明は、空調装置のエバポレータ等とコンデンサを互いに近接した位置に配置することで配管を短く簡素な形状にできるとともに、フロアパネルやキャビンを支持するダンパによってコンデンサも支持できる車体構造を提供する。また、フロアパネルにキャビンを載置する前の工程で空調装置の配管等を全て接続できる車体構造を提供する。 The present invention provides a vehicle body structure in which an evaporator of an air conditioner and a condenser and a condenser are arranged at positions close to each other so that piping can be made short and simple, and the condenser can be supported by a damper that supports a floor panel and a cabin.

　本発明の効果として、以下に示すような効果を奏する。 As the effects of the present invention, the following effects are obtained.
　第一の態様によれば、フロアパネルに固定されたサイドパネルにコンデンサを取り付けるため、空調装置のエバポレータ等とコンデンサを互いに近接した位置に配置して配管を短く簡素な形状にすることができる。これにより、コストの低減や生産性の向上を図ることが可能となる。 According to the first aspect, since the condenser is attached to the side panel fixed to the floor panel, the evaporator and the condenser of the air conditioner and the condenser can be arranged at positions close to each other to make the pipe short and simple. This makes it possible to reduce costs and improve productivity.

This makes it possible to reduce costs and improve productivity.
　第三の態様によれば、サイドパネルに各種の操作具や配管等が取り付けられるため、フロアパネルにキャビンを載置する前の工程で空調装置の配管等を全て接続することができる。これにより、コストの低減や生産性の向上を図ることが可能となる。 According to the third aspect, since various operation tools, piping, and the like are attached to the side panel, it is possible to connect all of the piping of the air conditioner in the step before placing the cabin on the floor panel. This makes it possible to reduce costs and improve productivity.
　第四の態様によれば、作業装置の後方であって操縦部の側方にコンデンサを配置するため、該コンデンサがオペレータの視界を遮らない。これにより、操縦性の向上や安全性の向上を図ることが可能となる。 According to the fourth aspect, since the capacitor is disposed behind the working device and on the side of the control unit, the capacitor does not block the operator's view. This makes it possible to improve maneuverability and safety.

　次に、発明の実施の形態を説明する。 Next, an embodiment of the invention will be described.
　まず、図１を用いて、作業車両であるバックホー１００の全体構成について説明する。なお、本発明の技術的思想は、以下に説明するバックホー１００に限るものではなく、その他の建設機械や農業機械等、作業車両全般に適用することが可能である。 First, the overall configuration of the backhoe 100 as a work vehicle will be described with reference to FIG. The technical idea of the present invention is not limited to the backhoe 100 described below, but can be applied to work vehicles in general such as other construction machines and agricultural machines.
　図１に示すように、バックホー１００は、主に走行装置１と、作業装置２と、旋回装置３と、で構成されている。 As shown in FIG. 1, the backhoe 100 mainly includes a traveling device 1, a work device 2, and a turning device 3.
　走行装置１は、バックホー１００を走行させるものである。走行装置１は、左右一対のクローラ１１や油圧モータ１２等で構成される。走行装置１は、油圧モータ１２が左右のクローラ１１を駆動することで前後進を可能としている。また、走行装置１は、油圧モータ１２が左右のクローラ１１を独立して駆動することで旋回を可能としている。 The traveling device 1 is for driving the backhoe 100. The traveling device 1 includes a pair of left and right crawlers 11, a hydraulic motor 12, and the like. The traveling device 1 can move forward and backward by the hydraulic motor 12 driving the left and right crawlers 11. Further, the traveling device 1 can turn by the hydraulic motor 12 driving the left and right crawlers 11 independently.
　作業装置２は、土砂等の掘削作業を行なうものである。作業装置２は、ブーム２１やアーム２２、バケット２３等で構成される。作業装置２は、これらを駆動することで掘削作業を可能としている。 Work device 2 performs excavation work such as earth and sand. The work device 2 includes a boom 21, an arm 22, a bucket 23, and the like. The work device 2 enables excavation work by driving them.
　具体的に説明すると、ブーム２１は、その一端部が旋回装置３の前部に支持されており、伸縮自在に可動するブームシリンダ２１１によって回動される。また、アーム２２は、その一端部がブーム２１の他端部に支持されており、伸縮自在に可動するアームシリンダ２２１によって回動される。そして、バケット２３は、その一端部がアーム２２の他端部に支持されており、伸縮自在に可動するバケットシリンダ２３１によって回動される。つまり、作業装置２は、三箇所の回動部を有する多関節構造を構成している。こうして、作業装置２は、これらを同時に又は互いに独立して駆動することで掘削作業を可能としている。 More specifically, one end of the boom 21 is supported by the front portion of the turning device 3 and is rotated by a boom cylinder 211 that is movable in a telescopic manner. Further, one end of the arm 22 is supported by the other end of the boom 21 and is rotated by an arm cylinder 221 that is movable in a telescopic manner. The bucket 23 is supported at one end by the other end of the arm 22 and rotated by a bucket cylinder 231 that is movable in a telescopic manner. That is, the working device 2 constitutes an articulated structure having three rotating parts. Thus, the work device 2 enables excavation work by driving them simultaneously or independently of each other.
　旋回装置３は、作業装置２を旋回させるものである。旋回装置３は、旋回台３１や油圧モータ３２等から構成される。旋回装置３は、油圧モータ３２が旋回台３１を駆動することで作業装置２を旋回可能としている。また、旋回装置３には、操縦部３３やエンジン３４が配置されている。 The turning device 3 turns the work device 2. The swivel device 3 includes a swivel base 31, a hydraulic motor 32, and the like. The swivel device 3 enables the work device 2 to swivel when the hydraulic motor 32 drives the swivel base 31. In addition, a steering unit 33 and an engine 34 are arranged in the turning device 3.
　詳細に説明すると、操縦部３３には、操縦席３３１や各種の操作具３３２が備えられている。そして、操縦席３３１や操作具３３２は、キャビン３３３によって覆われている。オペレータは、操縦席３３１に着座した状態で操作具３３２を操作することによってエンジン３４の制御を行なう。また、オペレータは、操作具３３２を操作することによって各モータ１２・３２や各シリンダ２１１・２２１・２３１の制御を行なう。こうして、オペレータは、バックホー１００の操縦を行なうのである。 More specifically, the control unit 33 is provided with a cockpit 331 and various operation tools 332. The cockpit 331 and the operation tool 332 are covered with a cabin 333. The operator controls the engine 34 by operating the operation tool 332 while sitting on the cockpit 331. The operator controls the motors 12 and 32 and the cylinders 211, 221 and 231 by operating the operation tool 332. Thus, the operator operates the backhoe 100.
　更に、操縦部３３には、空調装置４を構成するエキスパンションバルブ４４やエバポレータ４５等が備えられている（図４参照）。本バックホー１００において、エキスパンションバルブ４４やエバポレータ４５等は、操縦席３３１の側方に取り付けられたインストルメントパネル３３４内に納められている（図４参照）。 Furthermore, the control unit 33 is provided with an expansion valve 44, an evaporator 45, and the like constituting the air conditioner 4 (see FIG. 4). In the backhoe 100, the expansion valve 44, the evaporator 45, and the like are housed in an instrument panel 334 attached to the side of the cockpit 331 (see FIG. 4).
　ここで、空調装置４の構成について簡単に説明する。なお、説明の簡単のために、冷房機能部分に着目して説明する。 Here, the configuration of the air conditioner 4 will be briefly described. For the sake of simplicity of explanation, the explanation will be given focusing on the cooling function portion.
　図２は、空調装置４の構成を示す図である。図中の白い矢印は、空気の流れ方向を示している。図中の黒い矢印は、冷媒の流れ方向を示している。 FIG. 2 is a diagram showing the configuration of the air conditioner 4. White arrows in the figure indicate the direction of air flow. The black arrows in the figure indicate the direction of refrigerant flow.
　空調装置４は、主にコンプレッサ４１と、コンデンサ４２と、レシーバ４３と、エキスパンションバルブ４４と、エバポレータ４５と、で構成されている。また、空調装置４は、冷媒を案内する配管４６や空気を案内するブロア４７及びファン４８を備えている。 The air conditioner 4 mainly includes a compressor 41, a condenser 42, a receiver 43, an expansion valve 44, and an evaporator 45. The air conditioner 4 includes a pipe 46 that guides the refrigerant, a blower 47 that guides the air, and a fan 48.
　コンプレッサ４１は、気体状の冷媒を圧縮するものである。コンプレッサ４１は、キャビン３３３の外部に配置され（図１参照）、エンジン３４によって駆動される。冷媒は、例えばロータの回転によって空間に押し込められ、圧縮される。 The compressor 41 compresses a gaseous refrigerant. The compressor 41 is disposed outside the cabin 333 (see FIG. 1) and is driven by the engine 34. The refrigerant is pushed into the space by, for example, rotation of the rotor and compressed.
　コンデンサ４２は、気体状の冷媒を液化するものである。コンデンサ４２は、キャビン３３３の外部に配置され（図３、図４、図５、図６参照）、ファン４８によって空気が送られる。冷媒は、フィンが設けられた配管の内部を流れることで放熱し、液化される。 The capacitor 42 liquefies gaseous refrigerant. The condenser 42 is disposed outside the cabin 333 (see FIGS. 3, 4, 5, and 6), and air is sent by the fan 48. The refrigerant dissipates heat and liquefies by flowing inside the pipe provided with the fins.
　レシーバ４３は、液体状の冷媒を貯溜するとともに異物を除去するものである。レシーバ４３は、キャビン３３３の外部であってコンデンサ４２の近傍に配置されている（図４、図５、図６参照）。冷媒は、レシーバボディの内部に一時的に貯溜され、フィルタによって異物が除去される。 The receiver 43 stores liquid refrigerant and removes foreign matters. The receiver 43 is disposed outside the cabin 333 and in the vicinity of the capacitor 42 (see FIGS. 4, 5, and 6). The refrigerant is temporarily stored inside the receiver body, and foreign matters are removed by the filter.
　エキスパンションバルブ４４は、冷媒を霧化してエバポレータ４５に供給するものである。エキスパンションバルブ４４は、キャビン３３３の内部に配置されている。より詳細に説明すると、エキスパンションバルブ４４は、インストルメントパネル３３４の内部に配置されている（図４参照）。冷媒は、例えば感熱部４４１に封入されたガスの膨張又は収縮によってエバポレータ４５への供給量が調節される。 The expansion valve 44 atomizes the refrigerant and supplies it to the evaporator 45. The expansion valve 44 is disposed inside the cabin 333. If it demonstrates in detail, the expansion valve 44 will be arrange | positioned inside the instrument panel 334 (refer FIG. 4). The supply amount of the refrigerant to the evaporator 45 is adjusted by, for example, the expansion or contraction of the gas sealed in the heat sensitive unit 441.
　エバポレータ４５は、霧状の冷媒を気化するものである。エバポレータ４５は、キャビン３３３の内部に配置されている。より詳細に説明すると、エバポレータ４５は、インストルメントパネル３３４の内部であってエキスパンションバルブ４４の近傍に配置されている（図４参照）。冷媒は、フィンが設けられた管の内部を流れることで吸熱し、気化される。 The evaporator 45 vaporizes the mist refrigerant. The evaporator 45 is disposed inside the cabin 333. More specifically, the evaporator 45 is disposed inside the instrument panel 334 and in the vicinity of the expansion valve 44 (see FIG. 4). The refrigerant absorbs heat and vaporizes by flowing inside the pipe provided with the fins.
　なお、エバポレータ４５には、ブロア４７によって空気が送られる。従って、エバポレータ４５に送られた空気は、該エバポレータ４５を通り抜ける際に熱を奪われて温度が低下することとなる。こうして、空調装置４は、温度が低下した空気を吹き出し口３３４ｈから排出可能としているのである（図３、図４、図５、図６参照）。 Note that air is sent to the evaporator 45 by the blower 47. Therefore, the air sent to the evaporator 45 is deprived of heat when passing through the evaporator 45 and the temperature is lowered. In this way, the air conditioner 4 can discharge the air whose temperature has decreased from the outlet 334h (see FIGS. 3, 4, 5, and 6).
　次に、本発明の一実施形態に係るバックホー１００の車体構造５について説明する。 Next, the vehicle body structure 5 of the backhoe 100 according to an embodiment of the present invention will be described.
　図３は、操縦部３３を示す図である。図４は、操縦部３３を図３における矢印Ｘの方向から見た図である。図５は、操縦部３３を図３における矢印Ｙの方向から見た図である。図６は、操縦部３３を図３における矢印Ｚの方向から見た図である。 FIG. 3 is a diagram showing the control unit 33. 4 is a view of the control unit 33 as viewed from the direction of the arrow X in FIG. FIG. 5 is a view of the control unit 33 viewed from the direction of the arrow Y in FIG. 6 is a view of the control unit 33 as viewed from the direction of the arrow Z in FIG.
　ここで、上述の車体構造５とは、操縦部３３を支持する構造をいう。より詳細に説明すると、車体構造５とは、操縦部３３を構成する操縦席３３１やキャビン３３３等を支持する構造をいう。本実施形態に係る車体構造５は、以下のように構成されている。 Here, the above-described vehicle body structure 5 refers to a structure that supports the control unit 33. More specifically, the vehicle body structure 5 refers to a structure that supports the cockpit 331, the cabin 333, and the like that constitute the steering section 33. The vehicle body structure 5 according to the present embodiment is configured as follows.
　本実施形態に係る車体構造５は、主にフロアパネル５１と、サイドパネル５２と、で構成されている。 The vehicle body structure 5 according to the present embodiment mainly includes a floor panel 51 and a side panel 52.
　フロアパネル５１は、操縦部３３の床面を構成する鋼板部品である。フロアパネル５１は、旋回台３１の上面に沿うように配置され、操縦席３３１等が取り付けられる。また、フロアパネル５１には、操縦席３３１等を覆うようにキャビン３３３が載置されている（図４、図６参照）。 The floor panel 51 is a steel plate component that constitutes the floor surface of the control unit 33. The floor panel 51 is disposed along the upper surface of the swivel base 31, and a cockpit 331 or the like is attached thereto. Further, a cabin 333 is placed on the floor panel 51 so as to cover the cockpit 331 and the like (see FIGS. 4 and 6).
　サイドパネル５２は、操縦部３３の側面を構成する鋼板部品である。サイドパネル５２は、フロアパネル５１に固定され、インストルメントパネル３３４等が取り付けられる。また、サイドパネル５２には、コンデンサ４２が取り付けられている（図３、図４、図５、図６参照）。 The side panel 52 is a steel plate component that constitutes the side surface of the control unit 33. The side panel 52 is fixed to the floor panel 51, and an instrument panel 334 or the like is attached thereto. In addition, a capacitor 42 is attached to the side panel 52 (see FIGS. 3, 4, 5, and 6).
　このように、本バックホー１００においては、フロアパネル５１に固定されたサイドパネル５２にコンデンサ４２を取り付けるため、空調装置４のエバポレータ４５等とコンデンサ４２を互いに近接した位置に配置して配管４６を短く簡素な形状にすることができる。これにより、コストの低減や生産性の向上を図ることが可能となる。 Thus, in this backhoe 100, in order to attach the condenser 42 to the side panel 52 fixed to the floor panel 51, the evaporator 45 and the like of the air conditioner 4 and the condenser 42 are arranged at positions close to each other to shorten the pipe 46. A simple shape can be obtained. This makes it possible to reduce costs and improve productivity.
　また、本実施形態に係る車体構造５は、例えばエンジン３４の運転によって発生する振動をオペレータに伝えないようにするため、ダンパ５３が備えられている。 In addition, the vehicle body structure 5 according to the present embodiment is provided with a damper 53 so as not to transmit vibrations generated by, for example, operation of the engine 34 to the operator.
　ダンパ５３は、ゴム等が弾性変形することによって振動を吸収する弾性部品である。ダンパ５３は、フロアパネル５１に固定され、該フロアパネル５１やキャビン３３３を支持する。なお、ダンパ５３は、コンデンサ４２がサイドパネル５２に取り付けられていることから、フロアパネル５１やキャビン３３３とともにコンデンサ４２も支持することとなる（図３、図４、図５、図６参照）。 The damper 53 is an elastic part that absorbs vibration when rubber or the like is elastically deformed. The damper 53 is fixed to the floor panel 51 and supports the floor panel 51 and the cabin 333. In addition, since the capacitor | condenser 42 is attached to the side panel 52, the damper 53 will also support the capacitor | condenser 42 with the floor panel 51 and the cabin 333 (refer FIG.3, FIG.4, FIG.5, FIG.6).
　このように、本バックホー１００においては、フロアパネル５１に固定されたダンパ５３によってコンデンサ４２も支持するため、該コンデンサ４２を支持するための別途のダンパが不要となる。これにより、コストの低減や生産性の向上を図ることが可能となる。 Thus, in this backhoe 100, the capacitor 42 is also supported by the damper 53 fixed to the floor panel 51, so that a separate damper for supporting the capacitor 42 becomes unnecessary. This makes it possible to reduce costs and improve productivity.
　更に、本実施形態に係る車体構造５の特徴として、サイドパネル５２には、アクセルレバー３３２ａやブレードレバー３３２ｂ等の各種の操作具３３２が取り付けられる（図５、図６参照）。また、サイドパネル５２には、空調装置４の配管４６や油圧装置の配管等が取り付けられる（図示せず）。 Furthermore, as a feature of the vehicle body structure 5 according to the present embodiment, various operation tools 332 such as an accelerator lever 332a and a blade lever 332b are attached to the side panel 52 (see FIGS. 5 and 6). In addition, the side panel 52 is attached with a pipe 46 of the air conditioner 4 and a pipe of a hydraulic device (not shown).
　このように、本バックホー１００においては、サイドパネル５２に各種の操作具３３２や配管４６等が取り付けられるため、フロアパネル５１にキャビン３３３を載置する前の工程で空調装置４の配管４６等を全て接続することができる（特に空調装置４については、サブアセンブリ工程を経て配管４６等が接続された半完成品の状態で搭載することもできる）。これにより、コストの低減や生産性の向上を図ることが可能となる。 As described above, in the present backhoe 100, since various operation tools 332, pipes 46, and the like are attached to the side panel 52, the pipes 46 and the like of the air conditioner 4 are installed in the process before the cabin 333 is placed on the floor panel 51. All of them can be connected (particularly, the air conditioner 4 can be mounted in a semi-finished product state in which the piping 46 and the like are connected through the sub-assembly process). This makes it possible to reduce costs and improve productivity.
　つまり、図７に示すように、本バックホー１００においては、空調装置４の配管４６等を全て接続した後にフロアパネル５１にキャビン３３３を載置することが可能であり、一連の組立作業を単純化できるのである。これにより、コストの低減や生産性の向上を図ることが可能となる。 That is, as shown in FIG. 7, in the backhoe 100, it is possible to place the cabin 333 on the floor panel 51 after all the pipes 46 and the like of the air conditioner 4 are connected, simplifying a series of assembly operations. It can be done. This makes it possible to reduce costs and improve productivity.
　次に、本実施形態に係る車体構造５のその他の特徴について説明する。 Next, other features of the vehicle body structure 5 according to this embodiment will be described.
　本実施形態に係る車体構造５においては、コンデンサ４２が作業装置２の後方であって操縦部３３の側方に配置されることを特徴としている（図５参照）。これは、オペレータの視界を広く確保することを目的として決定された位置である。即ち、これは、図８中に示す死角領域Ｂが大きくならないように考慮され、決定された位置である。 In the vehicle body structure 5 according to the present embodiment, the capacitor 42 is arranged behind the work device 2 and on the side of the control unit 33 (see FIG. 5). This is a position determined for the purpose of ensuring a wide field of view of the operator. That is, this is a position determined in consideration so that the blind spot area B shown in FIG. 8 does not become large.
　このように、本バックホー１００においては、作業装置２の後方であって操縦部３３の側方にコンデンサ４２を配置するため、該コンデンサ４２がオペレータの視界を遮らない。これにより、操縦性の向上や安全性の向上を図ることが可能となる。 As described above, in the backhoe 100, the condenser 42 is disposed behind the work device 2 and on the side of the control unit 33, so that the condenser 42 does not block the operator's view. This makes it possible to improve maneuverability and safety.
