　本発明は整地板の上下振動によって地面を締め固める地固め装置に関する。 The present invention relates to a ground compaction device that compacts the ground by vertical vibration of a ground preparation plate.

When performing ground leveling work, while the operator grips the grip of the handle provided at the upper end of the rammer body, vertical vibration is applied to the ground leveling plate provided at the lower end of the rammer body, and the ground is leveled by this vibration. Is what you do.
　また、昨今の環境規制の高まりにより、エンジンの代わりに駆動源としてモータを使用し、燃料タンクをバッテリーに置き換えた電動地固め装置のニーズが高まりつつある。 In addition, due to the recent increase in environmental regulations, there is an increasing need for an electric consolidation device that uses a motor as a drive source instead of an engine and replaces the fuel tank with a battery.
特開２００２－３６３９１５号公報JP-A-2002-363915
　装置構成の電動化を想定した場合、バッテリー等の電装品は振動に対する耐久性が低いため、電装品に対する振動を抑制する必要がある。また、整地作業を行う際には、ハンドルの把持部に伝わる手腕振動による作業者の負担を低減するためにハンドルの振動を抑制する必要もある。 Assuming the electrification of the device configuration, it is necessary to suppress the vibration of the electrical components because the electrical components such as the battery have low durability against vibration. Further, when performing the ground leveling work, it is also necessary to suppress the vibration of the handle in order to reduce the burden on the operator due to the vibration of the hand and arm transmitted to the grip portion of the handle.
　特許文献１の装置構成において、燃料タンクの代わりにバッテリー等の電装品をハンドルに配置する場合、電装品に対する振動と、把持部に対する振動との双方を低減化するための防振対策を、ハンドルに施す必要が生じ得る。 In the device configuration of Patent Document 1, when an electrical component such as a battery is arranged on the handle instead of the fuel tank, anti-vibration measures for reducing both vibration of the electrical component and vibration of the grip portion are provided on the handle. May need to be applied to.
　しかしながら、電装品及び把持部のハンドル上の位置や質量はそれぞれ異なるため、電装品に対する防振対策と、把持部に対する防振対策とは、異なるものが必要とされる。そのため、ハンドルに対して、電装品及びハンドルの把持部のそれぞれに対応した異なる防振対策を施すことは困難となり得る。 However, since the positions and masses of the electrical components and the grip portion on the handle are different, different anti-vibration measures for the electrical components and the grip portion are required. Therefore, it may be difficult to apply different anti-vibration measures to the handle corresponding to the electrical components and the grip portion of the handle.
　本発明は、ハンドルとは別個に電装品の振動を低減することが可能な地固め装置の提供を目的とする。 An object of the present invention is to provide a consolidation device capable of reducing vibration of electrical components separately from a handle.
　本発明の一つの態様の地固め装置は、整地板と、前記整地板を駆動するモータとを有する地固め装置であって、
　前記地固め装置の上部半体に、ハンドルとは別個に防振部材を介して取付けられた支持部を備え、前記支持部に前記モータを駆動するための電装品が取付けられることを特徴とする。 The consolidation device according to one aspect of the present invention is a consolidation device having a ground preparation plate and a motor for driving the ground preparation plate.
The upper half of the consolidation device is provided with a support portion attached via a vibration isolator separately from the handle, and an electrical component for driving the motor is attached to the support portion.
　本発明によれば、ハンドルとは別個に電装品の振動を低減することが可能な地固め装置を提供することができる。 According to the present invention, it is possible to provide a consolidation device capable of reducing vibration of electrical components separately from the handle.

(Configuration example of consolidation device: rammer device)
FIG. 1 is a diagram showing a configuration of a rammer device 40A as a configuration example of the consolidation device according to the first embodiment. In FIG. 1, the right side of the paper is the front of the device, the left side of the paper is the rear of the device, and the direction of intersection in the front-rear direction is the vertical direction of the device. As shown in FIG. 1, the rammer device 40A includes a motor 10 that functions as a drive source, an upper portion above the vibration isolator member 41c described later (hereinafter, also referred to as “upper half body 41b”), and a stretchable vibration isolator. It has a member 41c, a lower portion below the anti-vibration member 41c (hereinafter, also referred to as "lower half body 41a"), and a ground leveling plate 42. The ground leveling plate 42 is connected to the lower half body 41a, and the lower half body 41a is connected to the upper half body 41b via the vibration isolator 41c.
　上部半体４１ｂには、ハンドル４５と、ハンドル４５とは別体の支持部７０とが設けられている。支持部７０には、バッテリーやＰＤＵ（パワードライブユニット）等の電装品を取付け可能な取付プレート５４が取付けられている。モータ１０に電力を供給するバッテリー５１は、取付プレート５４の上面に、保持トレイ５３を介して取付けられる。また、モータ１０の駆動を制御するＰＤＵ５５が配置されたＰＤＵケース５６は、取付プレート５４の下面に取付けられる。これら電装品の取付け構造については、後に図３を参照して詳細に説明する。 The upper half body 41b is provided with a handle 45 and a support portion 70 separate from the handle 45. A mounting plate 54 to which electrical components such as a battery and a PDU (Power Drive Unit) can be mounted is mounted on the support portion 70. The battery 51 that supplies electric power to the motor 10 is mounted on the upper surface of the mounting plate 54 via a holding tray 53. Further, the PDU case 56 in which the PDU 55 that controls the drive of the motor 10 is arranged is mounted on the lower surface of the mounting plate 54. The mounting structure of these electrical components will be described in detail later with reference to FIG.
　モータ１０は、スペーサ１５を介して上部半体４１ｂに取付けられており、バッテリー５１から供給された電力に基づいて駆動する。上部半体４１ｂの内部に収容された不図示の加振機構は、モータ１０の出力軸と連結されている。上部半体４１ｂから下部半体４１ａの内部にわたり形成されたクランクケース内で、モータ１０の出力軸の回転駆動は、不図示のピストンロッドにより往復直線運動（上下運動）に変換され、変換された上下運動は整地板４２に伝達される。これにより整地板４２が上下方向に振動する。整地板４２の振動により、地面ＧＮＤをたたいて締め固めていくことができる。 The motor 10 is attached to the upper half body 41b via the spacer 15 and is driven based on the electric power supplied from the battery 51. A vibration mechanism (not shown) housed inside the upper half body 41b is connected to the output shaft of the motor 10. In the crankcase formed from the upper half body 41b to the inside of the lower half body 41a, the rotational drive of the output shaft of the motor 10 is converted into a reciprocating linear motion (vertical motion) by a piston rod (not shown). The vertical movement is transmitted to the ground level plate 42. As a result, the ground level plate 42 vibrates in the vertical direction. By the vibration of the ground preparation plate 42, the ground GND can be struck and compacted.
　防振部材４１ｃは、上部半体４１ｂと下部半体４１ａとの間に設けられている。整地板４２が地面ＧＮＤをたたくことで、その反動がランマ装置４０Ａを上下動させるが、防振部材４１ｃの介在により、整地板４２及び下部半体４１ａ側の振動は低減した状態で上部半体４１ｂ側に伝達される。 The anti-vibration member 41c is provided between the upper half body 41b and the lower half body 41a. When the ground leveling plate 42 hits the ground GND, the reaction moves the rammer device 40A up and down, but the vibration on the ground leveling plate 42 and the lower half body 41a side is reduced by the intervention of the vibration isolator member 41c, and the upper half body. It is transmitted to the 41b side.
　（電装品の取付け構造）
　図３は電装品（バッテリー５１、ＰＤＵ５５）の取り付け構造を説明する図である。図３において、取付プレート５４は、支持部７０に取付けられるプレートであり、取付プレート５４の上面３５４Ａ（第１面）及び下面３５４Ｂ（第１面の裏面である第２面）に、バッテリー５１やＰＤＵ等の電装品が取付け可能である。 (Mounting structure of electrical components)
FIG. 3 is a diagram illustrating a mounting structure of electrical components (battery 51, PDU55). In FIG. 3, the mounting plate 54 is a plate to be mounted on the support portion 70, and the battery 51 and the battery 51 and the battery 51 and the battery 51 and the battery 51 and the lower surface 354B (the second surface which is the back surface of the first surface) of the mounting plate 54 Electrical components such as PDU can be attached.
　バッテリー５１を着脱可能に保持する保持トレイ５３は、取付プレート５４の上面３５４Ａに締結部材５３ｆ（例えば、ボルト）によって取り付けられる。バッテリー５１は、着脱可能に保持トレイ５３により保持され、保持トレイ５３を介して取付プレート５４の上面３５４Ａに取付けられる。バッテリー５１において、モータ接続部５１ａは、ＰＤＵ５５を介して、モータ１０と電気的に接続するコネクタケーブル５５ａと接続可能である。モータ１０とＰＤＵ５５とはケーブル５５ｂを介して電気的に接続されており、保持トレイ５３上にバッテリー５１が取付けられた状態でコネクタケーブル５５ａをモータ接続部５１ａに接続することで、モータ１０とバッテリー５１とが、コネクタケーブル５５ａ、ＰＤＵ５５及びケーブル５５ｂを介して電気的に接続した状態になる。 The holding tray 53 that detachably holds the battery 51 is attached to the upper surface 354A of the mounting plate 54 by a fastening member 53f (for example, a bolt). The battery 51 is detachably held by the holding tray 53, and is attached to the upper surface 354A of the mounting plate 54 via the holding tray 53. In the battery 51, the motor connection portion 51a can be connected to the connector cable 55a that is electrically connected to the motor 10 via the PDU 55. The motor 10 and the PDU 55 are electrically connected via a cable 55b, and the motor 10 and the battery are connected by connecting the connector cable 55a to the motor connection portion 51a with the battery 51 mounted on the holding tray 53. The 51 is electrically connected to the connector cable 55a, the PDU 55, and the cable 55b.
　外装部材５２（化粧部材）は、中央に開口部３５２を有している。外装部材５２は、取付プレート５４の上面３５４Ａに締結部材５２ａ（例えば、ボルト）によって取り付けられ、取付プレート５４上に取付けられた状態で、外装部材５２は、保持トレイ５３の外周及びバッテリー５１の下部を覆う。 The exterior member 52 (decorative member) has an opening 352 in the center. The exterior member 52 is attached to the upper surface 354A of the mounting plate 54 by a fastening member 52a (for example, a bolt), and in a state of being mounted on the mounting plate 54, the exterior member 52 is attached to the outer circumference of the holding tray 53 and the lower portion of the battery 51. Cover.
　ＰＤＵ５５は、保護用のＰＤＵケース５６内に配置され、ＰＤＵ５５が配置されたＰＤＵケース５６は、取付プレート５４の下面３５４Ｂに締結部材５６ａによって取り付けられる。 The PDU 55 is arranged in the protective PDU case 56, and the PDU case 56 in which the PDU 55 is arranged is attached to the lower surface 354B of the attachment plate 54 by the fastening member 56a.
　取付プレート５４の上面３５４Ａに電装品（電装品に含まれるバッテリー５１）を取付け、下面３５４Ｂに他の電装品（電装品に含まれる他の電装品（例えば、ＰＤＵ５５））を取付ける構造は、一方側の面（例えば、上面側）に電装品を積層する構造に比べて、取付プレート５４の下面側のスペースを有効利用することができるため、装置構成を小型化することができる。また、バッテリー５１は所定のタイミングで装置外部の充電器で充電する必要があるため、バッテリー５１の着脱頻度はＰＤＵ５５に比べて高くなる。着脱頻度の高いバッテリー５１を、着脱機構を有する保持トレイ５３を介して、取付プレート５４の上面３５４Ａ側に着脱可能に取付けることにより、作業者による作業効率の向上を図ることが可能になる。また、バッテリーの上面にバッテリー残量表示部を設けた場合には、作業者が作業中に残量を視認しやすくすることができるため、充電タイミングを把握しやすくなる。 One of the structures is such that the electrical component (battery 51 included in the electrical component) is attached to the upper surface 354A of the mounting plate 54 and the other electrical component (other electrical component (for example, PDU55) included in the electrical component) is attached to the lower surface 354B. Compared with the structure in which the electrical components are laminated on the side surface (for example, the upper surface side), the space on the lower surface side of the mounting plate 54 can be effectively used, so that the device configuration can be miniaturized. Further, since the battery 51 needs to be charged by a charger outside the device at a predetermined timing, the frequency of attachment / detachment of the battery 51 is higher than that of the PDU 55. By detachably attaching the battery 51, which is frequently attached and detached, to the upper surface 354A side of the attachment plate 54 via the holding tray 53 having the attachment / detachment mechanism, it is possible to improve the work efficiency by the operator. Further, when the battery remaining amount display unit is provided on the upper surface of the battery, the operator can easily visually recognize the remaining amount during the work, so that it becomes easy to grasp the charging timing.

It is attached to the connection portion 71b of 70b.
　図２の構成では、防振部材７３が、右フレーム７０ｂの接続部７１ｂに取付けられる構成例を示しているが、左フレーム７０ａについても同様であり、左フレーム７０ａの接続部７１ａに形成された貫通穴７１ｃと、防振部材７３のカラー７６とを貫通した回動支持部材７７ａが、回動係合部材７７ｂと係合することにより、防振部材７３が、左フレーム７０ａの接続部７１ａに取付けられる。 In the configuration of FIG. 2, the vibration isolator 73 is attached to the connecting portion 71b of the right frame 70b, but the same applies to the left frame 70a, which is formed in the connecting portion 71a of the left frame 70a.

It has a stepped portion 75d and a second flange portion 75c formed at the end of the stepped portion 75d. The first flange portion 75b is formed with an engaging portion 78b (for example, a screw hole) that engages with the fastening member 78a. Further, the second flange portion 75c is formed with a through hole 79b capable of penetrating the fastening member 79a (for example, a bolt).
　上部防振取付部材７４及び下部防振取付部材７５は、上下方向から防振部材７３を挟み込んだ状態で、締結部材７８ａを係合部７８ｂに係合させることにより、支持部７０に取付けられる。締結部材７８ａによる係合状態で、円弧部７４ａ及び円弧部７５ａは、防振部材本体７３ａの外周を上下方向から挟み、支持部７０を回動可能に保持するとともに、回動状態での支持部７０の位置を保持する。 The upper vibration-proof mounting member 74 and the lower vibration-proof mounting member 75 are attached to the support portion 70 by engaging the fastening member 78a with the engaging portion 78b while sandwiching the vibration-proof member 73 from the vertical direction. In the engaged state by the fastening member 78a, the arc portion 74a and the arc portion 75a sandwich the outer circumference of the vibration isolator main body 73a from the vertical direction, hold the support portion 70 rotatably, and support the support portion in the rotating state.

　第２フランジ部７５ｃを上部半体４１ｂ側の部品に当接させた状態で、締結部材７９ａを上部半体４１ｂ側の部品の係合部（例えば、螺子穴）と係合させることにより、支持部７０を、防振部材７３を介して、上部半体４１ｂに取付けることができる。図２では、ハンドル４５を保持するハンドル保持部材４４に第２フランジ部７５ｃを当接させて、締結部材７９ａで締結する例を示しているがこれに限らず、スペーサ１５から上方にフレームを伸ばし、該フレームに防振部材７３を介して支持部７０を設けてもよい。尚、第２フランジ部７５ｃの形状は平面状に限られず、当接する上部半体４１ｂ側の部品（ハンドル保持部材４４）の形状に合わせて形成することが可能である。例えば、ハンドル保持部材４４が円筒形状の外形を有する部品であれば、第２フランジ部７５ｃを円筒形状の外形に合わせた曲率を有する円弧形状として形成することも可能である。また、ハンドル保持部材４４が平面状の外形を有する部品であれば、第２フランジ部７５ｃを平坦に形成することも可能である。 With the second flange portion 75c in contact with the component on the upper half body 41b side, the fastening member 79a is supported by engaging with the engaging portion (for example, a screw hole) of the component on the upper half body 41b side. The portion 70 can be attached to the upper half body 41b via the vibration isolator member 73. FIG. 2 shows an example in which the second flange portion 75c is brought into contact with the handle holding member 44 holding the handle 45 and fastened by the fastening member 79a, but the present invention is not limited to this, and the frame is extended upward from the spacer 15. A support portion 70 may be provided on the frame via a vibration isolator member 73. The shape of the second flange portion 75c is not limited to a flat shape, and can be formed according to the shape of the part (handle holding member 44) on the upper half body 41b side that abuts. For example, if the handle holding member 44 is a component having a cylindrical outer shape, the second flange portion 75c can be formed as an arc shape having a curvature matching the outer shape of the cylindrical shape. Further, if the handle holding member 44 is a component having a flat outer shape, the second flange portion 75c can be formed flat.
　（ハンドル４５及び支持部７０の取付け構造）
　ハンドル４５は、防振部材７３と同様の構造を有するハンドル保持部材４４により、上部半体４１ｂに対して回動可能に取り付けられており、ハンドル保持部材４４の回転軸９０を回転中心として上下方向に回動可能に構成されている（図１）。支持部７０は、第２フランジ部７５ｃ（図２）の貫通穴７９ｂを貫通した締結部材７９ａとハンドル保持部材４４との係合により、ハンドル保持部材４４に取付けられ、防振部材７３の回転軸８０を回転中心として上下方向に回動可能に構成されている。 (Mounting structure of handle 45 and support 70)
The handle 45 is rotatably attached to the upper half body 41b by a handle holding member 44 having the same structure as the anti-vibration member 73, and is vertically oriented around the rotation axis 90 of the handle holding member 44. It is configured to be rotatable (Fig. 1). The support portion 70 is attached to the handle holding member 44 by engaging the fastening member 79a penetrating the through hole 79b of the second flange portion 75c (FIG. 2) with the handle holding member 44, and the rotation shaft of the vibration isolator member 73. It is configured to be rotatable in the vertical direction with 80 as the center of rotation.
　防振部材７３には、整地板４２から伝達される振動が防振部材７３の中心（回転軸８０）に加振力Ｆとして作用する。支持部７０は防振部材７３で支持された片持ち梁構造を有しており、加振力Ｆにより、片持ち梁構造の支持部７０が励振される。 The vibration transmitted from the ground leveling plate 42 acts on the vibration isolator 73 as a vibration exciting force F at the center of the vibration isolator 73 (rotation shaft 80). The support portion 70 has a cantilever structure supported by the vibration isolator member 73, and the support portion 70 of the cantilever structure is excited by the exciting force F.
　図１において、重心Ｇは、支持部７０及び電装品（バッテリー５１、ＰＤＵ５５）、外装部材５２、保持トレイ５３、取付プレート５４、ＰＤＵケース５６（以下、これらの全体的な構成を「支持ユニット」ともいう）の全体的な重心を示す。Ｌａは、防振部材７３の中心（回転軸８０）から支持ユニットの重心Ｇまでの距離（長さ）を示す。また、図１において、点Ｃは、電装品（バッテリー５１、ＰＤＵ５５）を取付プレート５４に取付ける位置（電装品の前後方向の中心位置）を示し、Ｌｂは重心Ｇから位置Ｃまでの距離（長さ）を示す。 In FIG. 1, the center of gravity G is a support portion 70, electrical components (battery 51, PDU 55), exterior member 52, holding tray 53, mounting plate 54, and PDU case 56 (hereinafter, the overall configuration thereof is referred to as a “support unit”. (Also known as) indicates the overall center of gravity. La indicates the distance (length) from the center of the vibration isolator 73 (rotational shaft 80) to the center of gravity G of the support unit. Further, in FIG. 1, the point C indicates the position where the electrical component (battery 51, PDU55) is mounted on the mounting plate 54 (the center position in the front-rear direction of the electrical component), and Lb is the distance (length) from the center of gravity G to the position C. ) Is shown.
　支持ユニットの重心Ｇの回りの慣性モーメントをＩＧ、支持ユニットの質量をＭとすると、加振力Ｆによる上下方向の振動の影響を受けない位置Ｃは、打撃中心の理論により、Ｌｂ＝ＩＧ／（Ｍ・Ｌａ）として求めることができる。Ｌｂにより定められる位置Ｃに電装品を取付けることにより、上下方向（並進方向）の振動の影響を低減することができる。 Assuming that the moment of inertia around the center of gravity G of the support unit is IG and the mass of the support unit is M, the position C, which is not affected by the vertical vibration due to the exciting force F, is Lb = IG / according to the theory of the center of impact. It can be obtained as (M · La). By attaching the electrical component to the position C determined by Lb, the influence of vibration in the vertical direction (translational direction) can be reduced.
　また、防振部材７３の弾性部材７２の弾性係数（ばね定数）を、ランマ装置４０Ａの振動周波数よりも十分小さく設定することにより共振による影響を低減することができる。 Further, the influence of resonance can be reduced by setting the elastic modulus (spring constant) of the elastic member 72 of the vibration isolator 73 to be sufficiently smaller than the vibration frequency of the rammer device 40A.
　ハンドル保持部材４４の内部においても、防振部材７３（図２のＳＴ２１）と同様に弾性部材が設けられている。支持部７０の防振部材７３及びハンドル４５のハンドル保持部材４４における弾性部材は、支持部７０の振動特性及びハンドル４５の振動特性に合わせて、異なる弾性係数を有する部材を使用することが可能である。支持部７０の防振部材７３は、ハンドル４５の防振部材（防振部材を含むハンドル保持部材４４）とは別個に、上部半体４１ｂと支持部７０の間に介在して設けられる。これにより、ハンドル４５と支持部７０に取付けられた電装品とに対する振動を個別に抑制することができる。本実施形態の装置構成によれば、ハンドルとは別個に電装品の振動を低減することができる。 Inside the handle holding member 44, an elastic member is provided as well as the anti-vibration member 73 (ST21 in FIG. 2). As the elastic member in the vibration isolator member 73 of the support portion 70 and the handle holding member 44 of the handle 45, it is possible to use a member having a different elastic modulus according to the vibration characteristic of the support portion 70 and the vibration characteristic of the handle 45. is there. The anti-vibration member 73 of the support portion 70 is provided between the upper half body 41b and the support portion 70, separately from the anti-vibration member of the handle 45 (the handle holding member 44 including the anti-vibration member). As a result, vibrations to the handle 45 and the electrical components attached to the support portion 70 can be individually suppressed. According to the device configuration of the present embodiment, it is possible to reduce the vibration of the electrical component separately from the handle.
　図１に示す装置構成では、側面視で、支持部７０はハンドル４５よりも下方に設けられており、ハンドル４５は、支持部７０に取付けられた電装品（例えば、バッテリー５１、ＰＤＵケース５６内に配置されたＰＤＵ５５）の少なくとも一部を覆うように構成されている。これにより、装置構成を小型化しつつ、かつ、ランマ装置４０Ａの不使用状態において、装置の転倒時等に電装品をハンドル４５で保護することができる。また、補強部材６３は、ハンドル４５を構成するハンドル右フレーム４８及びハンドル左フレーム４９の間に取付けられており、補強部材６３はバッテリー５１を保護する。補強部材６４は、ハンドル４５と上部半体４１ｂの可動プレート４３とを連結し、支持部７０に取付けられた電装品（例えば、バッテリー５１、ＰＤＵケース５６内に配置されたＰＤＵ５５）の少なくとも一部、およびモータ１０の少なくとも一部を覆う。これにより、装置の転倒時等に電装品およびモータ１０を補強部材６４で保護することができる。 In the device configuration shown in FIG. 1, the support portion 70 is provided below the handle 45 in a side view, and the handle 45 is inside an electrical component (for example, a battery 51 and a PDU case 56) attached to the support portion 70. It is configured to cover at least a part of the PDU 55) arranged in. As a result, it is possible to reduce the size of the device configuration and protect the electrical components with the handle 45 when the device falls over when the rammer device 40A is not in use. Further, the reinforcing member 63 is attached between the steering wheel right frame 48 and the steering wheel left frame 49 constituting the steering wheel 45, and the reinforcing member 63 protects the battery 51. The reinforcing member 64 connects the handle 45 and the movable plate 43 of the upper half body 41b, and is at least a part of the electrical components (for example, the battery 51 and the PDU 55 arranged in the PDU case 56) attached to the support portion 70. , And cover at least a portion of the motor 10. As a result, the electrical components and the motor 10 can be protected by the reinforcing member 64 when the device falls over.
　図４は、ランマ装置４０Ａを上方から見た図である。ハンドル４５は、前フレーム４７、後フレーム４６、及びハンドル右フレーム４８、ハンドル左フレーム４９を有し、略矩形状の枠体として形成される。また、支持部７０は、左右フレーム７０ａ、７０ｂ、及び中央フレーム７０ｃにより、略コの字形状の枠体として形成されており、支持部７０は、ハンドル４５の枠体の内側に配置される。作業者が整地作業を行う際には、ランマ装置４０Ａのハンドル４５の主に前フレーム４７（把手部）を把持して、ハンドル４５を上下方向に回動させ、下方に押し付ける操作が必要となるが、ハンドル４５の枠体の内側に、支持部７０を設けることにより、装置構成をコンパクトにするとともに、ハンドル４５の回動時に支持部７０との干渉を防止することができる。また、ハンドル保持部材４４を防振部材７３と別個に設けるとともに、電装品を支持部７０に設けている（ハンドル４５には電装品が設けられていない）ため、ハンドルを回動させた際に、電装品は連動して回動しないため、電装品が装置の他の部材（モータ等）と干渉することを抑制することができる。 FIG. 4 is a view of the rammer device 40A from above. The handle 45 has a front frame 47, a rear frame 46, a handle right frame 48, and a handle left frame 49, and is formed as a substantially rectangular frame. Further, the support portion 70 is formed as a substantially U-shaped frame body by the left and right frames 70a and 70b and the central frame 70c, and the support portion 70 is arranged inside the frame body of the handle 45. When the operator performs the ground leveling work, it is necessary to grip the front frame 47 (handle portion) of the handle 45 of the rammer device 40A, rotate the handle 45 in the vertical direction, and press the handle 45 downward. However, by providing the support portion 70 inside the frame body of the handle 45, it is possible to make the device configuration compact and prevent interference with the support portion 70 when the handle 45 rotates. Further, since the handle holding member 44 is provided separately from the vibration isolator member 73 and the electrical component is provided on the support portion 70 (the handle 45 is not provided with the electrical component), when the handle is rotated. Since the electrical components do not rotate in conjunction with each other, it is possible to prevent the electrical components from interfering with other members (motors, etc.) of the device.

As a result, it is possible to prevent interference with the support portion 70 when the handle 45 is rotated, while making the device configuration compact and lightweight.

　図１の例では、装置構成として、支持部７０がハンドル４５に比べて下方に配置されている例をしているが、この例の他、装置構成として、支持部７０がハンドル４５に比べて上方に配置される装置構成とすることも可能である。この場合、図２で示した下部防振取付部材７５における段差部７５ｄの上下方向の高さを、支持部７０がハンドル４５に比べて上方に配置される長さに形成したり、あるいは装置の上端部（上部半体４１ｂ）をハンドル４５よりも上方に突出形成し、該突出形成した部分に防振部材７３を介して支持部７０を設ければよい。 (Height of support 70 with respect to handle 45)
In the example of FIG. 1, as an apparatus configuration, the support portion 70 is arranged below the handle 45, but in addition to this example, as an apparatus configuration, the support portion 70 is compared with the handle 45. It is also possible to have a device configuration arranged above. In this case, the height of the step portion 75d in the lower anti-vibration mounting member 75 shown in FIG. 2 in the vertical direction may be formed to a length in which the support portion 70 is arranged above the handle 45, or the device may have a length. The upper end portion (upper half body 41b) may be formed so as to project above the handle 45, and the supporting portion 70 may be provided on the protruding portion via the vibration isolator member 73.

　支持部７０の構成として、支持部７０の防振部材７３を介して、電装品（バッテリー５１、ＰＤＵ５５）が取付けられている位置とは反対側に重量調整部を支持部７０に設けることも可能である。例えば、図４において、一点鎖線で示すように、支持部７０を構成する左右フレーム７０ａ、７０ｂを装置の後方側に延長した延長フレーム７０ｄ、７０ｅを形成し、重量調整部として、延長フレーム７０ｄ、７０ｅにカウンターウエイトＷを設けることも可能である。 (Weight adjustment part of support part 70)
As a configuration of the support portion 70, it is also possible to provide the support portion 70 with a weight adjusting portion on the side opposite to the position where the electrical components (battery 51, PDU 55) are attached via the vibration isolator member 73 of the support portion 70. Is. For example, in FIG. 4, as shown by the alternate long and short dash line, extension frames 70d and 70e are formed by extending the left and right frames 70a and 70b constituting the support portion 70 to the rear side of the device, and the extension frame 70d and 70d are used as weight adjusting portions. It is also possible to provide a counterweight W on the 70e.
　カウンターウエイトＷは重量の増減により調整可能であり、重量調整部（カウンターウエイトＷ）の重心Ｇの回りのモーメント（反時計回り方向）により、電装品の重心Ｇの回りのモーメント（時計回り方向）を低減することができる。電装品の重心Ｇの回りのモーメントを低減することにより、電装品が取付けられる位置Ｃを重心Ｇ側に移動させることができ、電装品から前方向に突出した支持部７０の突出長さＬ１（図１）を短くすることができる。支持部７０における突出長さＬ１を短くすることにより、支持部７０の中央フレーム７０ｃと、ハンドル４５の前フレーム４７とのクリアランスＬ２を拡大することがでる。これにより、装置構成をコンパクトにするとともに、ハンドル４５の回動時に支持部７０との干渉を、より一層防止することができる。 The counterweight W can be adjusted by increasing or decreasing the weight, and the moment around the center of gravity G of the weight adjusting unit (counterweight W) (counterclockwise) causes the moment around the center of gravity G of the electrical component (clockwise). Can be reduced. By reducing the moment around the center of gravity G of the electrical component, the position C where the electrical component is mounted can be moved to the center of gravity G side, and the protruding length L1 of the support portion 70 protruding forward from the electrical component ( Figure 1) can be shortened. By shortening the protruding length L1 of the support portion 70, the clearance L2 between the central frame 70c of the support portion 70 and the front frame 47 of the handle 45 can be increased. As a result, the device configuration can be made compact, and interference with the support portion 70 when the handle 45 is rotated can be further prevented.
　（支持部７０を板材で形成する構成）
　図２では、支持部７０として、複数のフレーム（左右フレーム７０ａ、７０ｂ、中央フレーム７０ｃ）の構成例を示したが、この例の他、板状の部材（板材）により支持部７０を構成してもよい。この場合、取付プレート５４の下面３５４Ｂに取り付けられたＰＤＵケース５６との干渉を回避するための開口部を板状の部材に形成すればよい。 (Structure in which the support portion 70 is formed of a plate material)
In FIG. 2, a configuration example of a plurality of frames (left and right frames 70a, 70b, central frame 70c) is shown as the support portion 70, but in addition to this example, the support portion 70 is configured by a plate-shaped member (plate material). You may. In this case, an opening for avoiding interference with the PDU case 56 attached to the lower surface 354B of the attachment plate 54 may be formed in a plate-shaped member.
　（取付プレート５４の変形例１（図７））
　図７は取付プレート５４の変形例１を示す図であり、ランマ装置４０Ａ（図１）を上方から見た図である。取付プレート５４に対する電装品（バッテリー５１、ＰＤＵ５５）の取り付け構造は図３、図４と同様であり、支持部７０の左右フレーム７０ａ、７０ｂの端部を防振部材７３に接続する構造は図２と同様である。また、支持部７０の重量調整部（カウンターウエイトＷ）の構造も図４と同様である。 (Modification example 1 of the mounting plate 54 (FIG. 7))
FIG. 7 is a diagram showing a modified example 1 of the mounting plate 54, and is a view of the rammer device 40A (FIG. 1) viewed from above. The mounting structure of the electrical components (battery 51, PDU55) to the mounting plate 54 is the same as in FIGS. 3 and 4, and the structure in which the ends of the left and right frames 70a and 70b of the support portion 70 are connected to the vibration isolator 73 is shown in FIG. Is similar to. Further, the structure of the weight adjusting portion (counterweight W) of the support portion 70 is the same as that in FIG.
　図７に示すように取付プレート５４は、平面視で矩形形状を有しており、締結部材５４ａ（例えば、ボルト）により支持部７０の上面を覆うように取付けられる。ここで、支持部７０は、左右フレーム７０ａ、７０ｂ及び中央フレーム７０ｃにより、略コの字形状の枠体として形成され、支持部７０の構成のうち破線で示す部分は取付プレート５４の下面に設けられる。 As shown in FIG. 7, the mounting plate 54 has a rectangular shape in a plan view, and is mounted so as to cover the upper surface of the support portion 70 by a fastening member 54a (for example, a bolt). Here, the support portion 70 is formed as a substantially U-shaped frame by the left and right frames 70a and 70b and the central frame 70c, and the portion of the structure of the support portion 70 shown by the broken line is provided on the lower surface of the mounting plate 54. Be done.
　取付プレート５４を支持部７０に取付けた状態で、取付プレート５４の左端部２５４ａは支持部７０の左フレーム７０ａから枠体の外側に張り出している（張り出し長さＬｓ）。同様に取付プレート５４の右端部２５４ｂも支持部７０の右フレーム７０ｂから枠体の外側に張り出している（張り出し長さＬｓ）。また、取付プレート５４の前端部２５４ｃは中央フレーム７０ｃから枠体の外側に張り出している（張り出し長さＬｆ）。尚、前端部２５４ｃの張り出し長さＬｆを、左端部２５４ａ及び右端部２５４ｂの張り出し長さＬｓと同様に形成することも可能である（Ｌｆ＝Ｌｓ）。また、作業者がハンドル４５の前フレーム４７を把持しやすいように、前端部２５４ｃの張り出し長さＬｆを左端部２５４ａ及び右端部２５４ｂの張り出し長さＬｓに比べて短く形成することも可能である（Ｌｆ＜Ｌｓ）。 With the mounting plate 54 mounted on the support portion 70, the left end portion 254a of the mounting plate 54 projects from the left frame 70a of the support portion 70 to the outside of the frame body (overhang length Ls). Similarly, the right end portion 254b of the mounting plate 54 also projects from the right frame 70b of the support portion 70 to the outside of the frame body (overhang length Ls). Further, the front end portion 254c of the mounting plate 54 projects from the central frame 70c to the outside of the frame body (overhang length Lf). It is also possible to form the overhang length Lf of the front end portion 254c in the same manner as the overhang length Ls of the left end portion 254a and the right end portion 254b (Lf = Ls). Further, the overhang length Lf of the front end portion 254c can be made shorter than the overhang length Ls of the left end portion 254a and the right end portion 254b so that the operator can easily grip the front frame 47 of the handle 45. (Lf <Ls).
　図７に示す取付プレート５４の変形例１の構成によれば、取付プレート５４が支持部７０に当接する領域（図７において破線で示す支持部７０の領域）を増やすことができるため、支持部７０の左フレーム７０ａ、右フレーム７０ｂ及び中央フレーム７０ｃに対する締結部材５４ａの数を増やすことができる。 According to the configuration of the modification 1 of the mounting plate 54 shown in FIG. 7, the region where the mounting plate 54 abuts on the support portion 70 (the region of the support portion 70 shown by the broken line in FIG. 7) can be increased, so that the support portion The number of fastening members 54a with respect to the left frame 70a, the right frame 70b, and the center frame 70c of the 70 can be increased.
　例えば、図４に示した例では、取付プレート５４は、左フレーム７０ａに対して２箇所の締結部材５４ａより取り付けられ、右フレーム７０ｂに対して２箇所の締結部材５４ａにより取り付けられている。これに対して、図７に示した例では、取付プレート５４は、左フレーム７０ａに対して３箇所の締結部材５４ａより取り付けられ、右フレーム７０ｂに対して３箇所の締結部材５４ａにより取り付けられ、更に、中央フレーム７０ｃに対して２箇所の締結部材５４ａにより取り付けられている。これにより、取付プレート５４を支持部７０上面に安定した状態で配置することができ、取付プレート５４の外縁を支持部７０に対して、より強固に取り付けることが可能になる。 For example, in the example shown in FIG. 4, the mounting plate 54 is attached to the left frame 70a by two fastening members 54a, and is attached to the right frame 70b by two fastening members 54a. On the other hand, in the example shown in FIG. 7, the mounting plate 54 is attached to the left frame 70a by three fastening members 54a and attached to the right frame 70b by three fastening members 54a. Further, it is attached to the central frame 70c by two fastening members 54a. As a result, the mounting plate 54 can be arranged on the upper surface of the support portion 70 in a stable state, and the outer edge of the mounting plate 54 can be more firmly attached to the support portion 70.
　（取付プレート５４の変形例２（図８））
　図８は取付プレート５４の変形例２を示す図であり、ランマ装置４０Ａ（図１）を上方から見た図である。図８に示すように取付プレート５４は、平面視で矩形形状を有しており、締結部材５４ａ（例えば、ボルト）により支持部７０の上面を覆うように取付けられる構造は図７の変形例１と同様である。支持部７０の構成のうち破線で示す部分は取付プレート５４の下面に設けられる。また、支持部７０の重量調整部（カウンターウエイトＷ）の構造は図４及び図７と同様である。但し、変形例２では装置幅ＷＤ２が変形例１の装置幅ＷＤ１に比べて狭いため（ＷＤ２＜ＷＤ１）、図８における取付プレート５４の左右方向の長さＬＰ２は、図７における取付プレート５４の左右方向の長さＬＰ１に比べて短く構成されている（ＬＰ２＜ＬＰ１）。 (Modification 2 of the mounting plate 54 (FIG. 8))
FIG. 8 is a diagram showing a modification 2 of the mounting plate 54, and is a view of the rammer device 40A (FIG. 1) viewed from above. As shown in FIG. 8, the mounting plate 54 has a rectangular shape in a plan view, and a structure in which the mounting plate 54 is mounted so as to cover the upper surface of the support portion 70 by a fastening member 54a (for example, a bolt) is a modification 1 of FIG. Is similar to. The portion of the structure of the support portion 70 shown by the broken line is provided on the lower surface of the mounting plate 54. Further, the structure of the weight adjusting portion (counterweight W) of the support portion 70 is the same as that in FIGS. 4 and 7. However, in the second modification, the device width WD2 is narrower than the device width WD1 of the first modification (WD2 <WD1), so that the horizontal length LP2 of the mounting plate 54 in FIG. 8 is the mounting plate 54 in FIG. The length in the left-right direction is shorter than that of LP1 (LP2 <LP1).
　支持部７０の左右フレーム７０ａ、７０ｂの端部を防振部材７３に接続する構造は図２と同様であるが、図８の変形例２では、取付プレート５４に対する電装品（バッテリー５１）を取付ける向きが図４、図７における取付け向きと相違している。例えば、図７において、バッテリー５１は長手方向がランマ装置４０Ａの左右方向に沿って配置されているが、図８の変形例２では、バッテリー５１は長手方向がランマ装置４０Ａの前後方向に沿って配置されている。 The structure for connecting the ends of the left and right frames 70a and 70b of the support portion 70 to the vibration isolator member 73 is the same as in FIG. 2, but in the second modification of FIG. 8, the electrical component (battery 51) is attached to the mounting plate 54. The orientation is different from the mounting orientation in FIGS. 4 and 7. For example, in FIG. 7, the battery 51 is arranged in the longitudinal direction along the left-right direction of the rammer device 40A, but in the modified example 2 of FIG. 8, the battery 51 is arranged in the longitudinal direction along the front-rear direction of the rammer device 40A. Have been placed.
　図８に示す取付プレート５４の変形例２の構成によれば、変形例１と同様に
取付プレート５４を支持部７０上面に安定した状態で配置することができ、取付プレート５４の外縁を支持部７０に対して、より強固に取り付けることが可能になる。更に、変形例２の構成によれば、変形例１のランマ装置４０Ａの装置幅（ＷＤ１）に比べて、変形例２のランマ装置４０Ａの装置幅（ＷＤ２）を低減することができ（ＷＤ２＜ＷＤ１）、よりコンパクトなランマ装置４０Ａを提供することが可能になる。 According to the configuration of the deformation example 2 of the mounting plate 54 shown in FIG. 8, the mounting plate 54 can be stably arranged on the upper surface of the support portion 70 as in the modification 1, and the outer edge of the mounting plate 54 is the support portion. It becomes possible to attach more firmly to 70. Further, according to the configuration of the modified example 2, the device width (WD2) of the rammer device 40A of the modified example 2 can be reduced as compared with the device width (WD1) of the rammer device 40A of the modified example 1 (WD2 < WD1), it becomes possible to provide a more compact rammer device 40A.
　（取付プレート５４の変形例３（図９））
　図９は取付プレート５４の変形例３を示す図であり、ランマ装置４０Ａ（図１）を上方から見た図である。図９に示すように取付プレート５４は、平面視で矩形形状を有しており、締結部材５４ａ（例えば、ボルト）により支持部７０の上面を覆うように取付けられる。支持部７０の構成のうち破線で示す部分は取付プレート５４の下面に設けられる。図９の変形例３では、支持部７０の構造が、図４の第１実施形態、図７及び図８の変形例１、２の構造と相違している。 (Modification 3 of the mounting plate 54 (FIG. 9))
FIG. 9 is a diagram showing a modified example 3 of the mounting plate 54, and is a view of the rammer device 40A (FIG. 1) viewed from above. As shown in FIG. 9, the mounting plate 54 has a rectangular shape in a plan view, and is mounted so as to cover the upper surface of the support portion 70 by a fastening member 54a (for example, a bolt). The portion of the structure of the support portion 70 shown by the broken line is provided on the lower surface of the mounting plate 54. In the modified example 3 of FIG. 9, the structure of the support portion 70 is different from the structure of the first embodiment of FIG. 4, and the structures of the modified examples 1 and 2 of FIGS. 7 and 8.
　図４、図７及び図８において、支持部７０は、左右フレーム７０ａ、７０ｂ及び中央フレーム７０ｃにより、略コの字形状の枠体として形成されているが、図９の変形例３において、支持部７０は、前後方向フレーム１７０ａ及び左右方向フレーム１７０ｂにより、略Ｔ字形状として形成されている点で相違している。図４の第１実施形態、図７及び図８の変形例１、２に比べて、支持部７０の剛性が低下しないように、図９の変形例３では、前後方向フレーム１７０ａ及び左右方向フレーム１７０ｂの部材幅ＷＤ４は、例えば、図７及び図８に示したフレーム（左フレーム７０ａ、右フレーム７０ｂ及び中央フレーム７０ｃ）の部材幅ＷＤ３に比べて幅広に形成されている（ＷＤ４＞ＷＤ３）。 In FIGS. 4, 7 and 8, the support portion 70 is formed as a substantially U-shaped frame by the left and right frames 70a and 70b and the central frame 70c, but in the third modification of FIG. 9, the support portion 70 is supported. The portion 70 is different in that it is formed in a substantially T-shape by the front-rear direction frame 170a and the left-right direction frame 170b. In the modified example 3 of FIG. 9, the front-rear direction frame 170a and the left-right direction frame are not lowered as compared with the first embodiment of FIG. 4, FIGS. 7 and 8, and the rigidity of the support portion 70 is not lowered. The member width WD4 of 170b is formed to be wider than the member width WD3 of the frames (left frame 70a, right frame 70b and center frame 70c) shown in FIGS. 7 and 8 (WD4> WD3).
　図９の変形例３では、部材幅ＷＤ４が部材幅ＷＤ３に比べて幅広に形成されている例を示しているが、この例に限られず、例えば、紙面に垂直な方向で、前後方向フレーム１７０ａ及び左右方向フレーム１７０ｂの部材厚さを、図７及び図８に示したフレーム（左フレーム７０ａ、右フレーム７０ｂ及び中央フレーム７０ｃ）の部材厚さに比べて厚く形成してもよい。支持部７０の断面特性（断面二次モーメント）が所定値になるように、部材幅及び部材厚のうち少なくともいずれか一方を形成することにより、図４、図７及び図８に示した支持部７０と同等の剛性を実現することができる。 In the modified example 3 of FIG. 9, an example in which the member width WD4 is formed wider than the member width WD3 is shown, but the present invention is not limited to this example, and for example, the frame 170a in the front-rear direction in the direction perpendicular to the paper surface. The member thickness of the horizontal frame 170b may be formed to be thicker than the member thickness of the frames (left frame 70a, right frame 70b, and center frame 70c) shown in FIGS. 7 and 8. The support portion shown in FIGS. 4, 7 and 8 is formed by forming at least one of the member width and the member thickness so that the cross-sectional characteristic (second moment of area) of the support portion 70 becomes a predetermined value. Rigidity equivalent to 70 can be realized.
　図４の第１実施形態、図７及び図８の変形例１、２では、支持部７０の左右フレーム７０ａ、７０ｂの端部が、それぞれ左右の防振部材７３に接続する構造であるが（図２）、図９の変形例３では、前後方向フレーム１７０ａの端部が単一の防振部材７３に接続する構造になっている。図９に示す取付プレート５４の変形例３の構成によれば、防振部材７３に接続するための部品点数（例えば、図２に示す弾性部材７２、上部防振取付部材７４、下部防振取付部材７５、カラー７６等）を低減することができ、防振部材７３に関する構造を簡素化することが可能になる。 In the first embodiment of FIG. 4, and the modified examples 1 and 2 of FIGS. 7 and 8, the ends of the left and right frames 70a and 70b of the support portion 70 are connected to the left and right anti-vibration members 73, respectively ( 2) and 9 have a structure in which the end portion of the front-rear frame 170a is connected to a single anti-vibration member 73. According to the configuration of the modification 3 of the mounting plate 54 shown in FIG. 9, the number of parts for connecting to the vibration-proof member 73 (for example, the elastic member 72, the upper vibration-proof mounting member 74, and the lower vibration-proof mounting shown in FIG. 2). (Member 75, collar 76, etc.) can be reduced, and the structure related to the vibration isolator 73 can be simplified.
　図４の第１実施形態、図７及び図８の変形例１、２では、重量調整部として左右のカウンターウエイトＷを使用している。図９の変形例３では、１つのカウンターウエイトとして２つ分のカウンターウエイト２Ｗを設けることで、図４の第１実施形態、図７及び図８の変形例１、２と同様の重量調整効果を実現することができる。 In the first embodiment of FIG. 4, and the modified examples 1 and 2 of FIGS. 7 and 8, the left and right counterweights W are used as the weight adjusting unit. In the modified example 3 of FIG. 9, by providing two counterweights 2W as one counterweight, the same weight adjustment effect as that of the first embodiment of FIG. 4, FIG. 7 and the modified examples 1 and 2 of FIG. 8 is provided. Can be realized.
　また、図４、図７及び図８において、ＰＤＵケース５６は取付プレート５４の下面３５４Ｂ（図３）に取り付けられる構造であるが、図９の変形例３では、前後方向フレーム１７０ａと交差し得るＰＤＵケース５６に切り欠き部５６ｂ、５６ｃ（図１０）を形成することで、前後方向フレーム１７０ａとの干渉を回避してＰＤＵケース５６を取付プレート５４の下面３５４Ｂ（図３）に取り付けることができる。これにより、変形例３においても、図４の第１実施形態、図７、図８の変形例１、２と同様に、取付プレート５４の下面側のスペースを有効利用することができるため、装置構成を小型化することができる。 Further, in FIGS. 4, 7 and 8, the PDU case 56 has a structure of being attached to the lower surface 354B (FIG. 3) of the attachment plate 54, but in the modified example 3 of FIG. 9, it may intersect the front-rear frame 170a. By forming the notches 56b and 56c (FIG. 10) in the PDU case 56, the PDU case 56 can be attached to the lower surface 354B (FIG. 3) of the attachment plate 54 while avoiding interference with the front-rear frame 170a. .. As a result, even in the modified example 3, the space on the lower surface side of the mounting plate 54 can be effectively used as in the first embodiment of FIG. 4, and the modified examples 1 and 2 of FIGS. The configuration can be miniaturized.
　図９の変形例３では、バッテリー５１は、図４の第１実施形態や図７の変形例１と同様に長手方向がランマ装置４０Ａの左右方向に沿って配置されている例を示している。バッテリー５１の配置方向は、この例に限られず、例えば、図８の変形例２のように、バッテリー５１の長手方向がランマ装置４０Ａの前後方向に沿って配置されるようにランマ装置４０Ａを構成してもよい。これにより、変形例２と同様に、変形例３のランマ装置４０Ａの装置幅を低減することができ、よりコンパクトなランマ装置４０Ａを提供することが可能になる。 In the third modification of FIG. 9, the battery 51 shows an example in which the longitudinal direction is arranged along the left-right direction of the rammer device 40A as in the first embodiment of FIG. 4 and the modification 1 of FIG. .. The arrangement direction of the battery 51 is not limited to this example, and the rammer device 40A is configured so that the longitudinal direction of the battery 51 is arranged along the front-rear direction of the rammer device 40A, for example, as in the modified example 2 of FIG. You may. As a result, the device width of the rammer device 40A of the modification 3 can be reduced as in the modification 2, and a more compact rammer device 40A can be provided.

　（地固め装置の構成例：プレートコンパクタ装置）
　第１実施形態では、地固め装置の構成例として、ランマ装置４０Ａの構成例を説明したが、この例の他、例えば、支持部７０および電装品（バッテリー５１、ＰＤＵ５５）の取付け構造を、プレートコンパクタ装置に適用することも可能である。図５は第２実施形態に係る地固め装置の構成例として、プレートコンパクタ装置４０Ｂの構成を示す図である。 [Second Embodiment]
(Configuration example of consolidation device: plate compactor device)
In the first embodiment, a configuration example of the rammer device 40A has been described as a configuration example of the consolidation device, but in addition to this example, for example, the mounting structure of the support portion 70 and the electrical components (battery 51, PDU55) may be mounted on a plate compactor. It can also be applied to devices. FIG. 5 is a diagram showing a configuration of a plate compactor device 40B as a configuration example of the consolidation device according to the second embodiment.
　プレートコンパクタ装置４０Ｂは、駆動源として機能するモータ１５０と、防振部材１４６より上側の上部半体１４４、１５４と、防振部材１４６と、防振部材１４６より下側の下部半体１４５と、励振機構１５８、整地板１４２とを有する。ハンドル１４７は第１実施形態で説明したハンドル４５と同様に略矩形状の枠体として構成される。上部半体１４４にハンドル１４７が取付けられている。整地板１４２は下部半体１４５に連結しており、励振機構１５８の振動により下部半体１４５及び整地板１４２が振動する。 The plate compactor device 40B includes a motor 150 that functions as a drive source, an upper half body 144 and 154 above the vibration isolator member 146, a vibration isolator member 146, and a lower half body 145 below the vibration isolator member 146. It has an excitation mechanism 158 and a ground preparation plate 142. The handle 147 is configured as a substantially rectangular frame like the handle 45 described in the first embodiment. A handle 147 is attached to the upper half body 144. The ground preparation plate 142 is connected to the lower half body 145, and the lower half body 145 and the ground preparation plate 142 vibrate due to the vibration of the excitation mechanism 158.
　図５において、モータ１５０はスペーサ１５１を介して上部半体１５４内に設けられており、モータ１５０の出力軸１５０ａには駆動プーリ１５２が取付けられている。また、励振機構１５８の回転軸１５３ａには従動プーリ１５３が取付けられており、駆動プーリ１５２と従動プーリ１５３との間には動力伝達機構１５５（ドライブベルト）が設けられている。モータ１５０の回転駆動力は、駆動プーリ１５２、動力伝達機構１５５、従動プーリ１５３を介して励振機構１５８に伝達され、伝達された回転駆動力に基づいた励振機構１５８の振動により下部半体１４５及び整地板１４２が振動する。 In FIG. 5, the motor 150 is provided in the upper half body 154 via the spacer 151, and the drive pulley 152 is attached to the output shaft 150a of the motor 150. A driven pulley 153 is attached to the rotating shaft 153a of the excitation mechanism 158, and a power transmission mechanism 155 (drive belt) is provided between the drive pulley 152 and the driven pulley 153. The rotational driving force of the motor 150 is transmitted to the exciting mechanism 158 via the driving pulley 152, the power transmission mechanism 155, and the driven pulley 153, and the lower half body 145 and the lower half body 145 and the vibration of the exciting mechanism 158 based on the transmitted rotational driving force are transmitted. The leveling plate 142 vibrates.
　整地板１４２の振動に対する反動がプレートコンパクタ装置４０Ｂを上下動させるが、防振部材１４６の介在により、整地板１４２及び下部半体１４５側の振動は低減され、上部半体１４４、１５４、及び上部半体１４４に取付けられたハンドル１４７側に伝達される。防振部材１４６は、上部半体１４４、１５４、及び上部半体１４４に取付けられたハンドル１４７の防振部材として機能し、後述する支持部７０の防振部材７３とは別個の構成である。 The reaction to the vibration of the ground preparation plate 142 moves the plate compactor device 40B up and down, but the vibration on the ground preparation plate 142 and the lower half body 145 side is reduced by the intervention of the vibration isolator 146, and the upper half body 144, 154, and the upper part are reduced.
