Description
【考案の詳細な説明】 イ.考案の目的 (産業上の利用分野) 本考案は、旋回台上にブーム等の作業機を備えてなる作
業装置に関し、さらには、この作業装置を所定位置に格
納するための装置に関する。[Detailed Description of Device] a. Object of the Invention (Industrial field of application) The present invention relates to a working device provided with a working machine such as a boom on a swivel base, and further to a device for storing the working device in a predetermined position.
(従来の技術) 高所作業車、クレーン車等の作業車には、その車体に対
して旋回自在な旋回台とその旋回台上に取り付けられた
ブームとからなる作業装置が搭載されている。このよう
な作業車を用いて作業を行うときは、作業者は、ブーム
先端に取り付けられた作業台上もしくは旋回台上に取り
付けられた操作席から旋回台の旋回操作もしくはブーム
の起伏、伸縮操作等を行う。(Prior Art) A work vehicle such as an aerial work vehicle or a crane vehicle is equipped with a work device including a swivel base that is rotatable about its vehicle body and a boom mounted on the swivel base. When performing work using such a work vehicle, the operator must turn the swivel platform, or raise and lower the boom, and extend and retract from the operator's seat mounted on the work platform mounted on the tip of the boom or on the swivel platform. And so on.
ところで、作業時以外では、上記ブームは作業車の車体
上に設けられたブーム支持台上に格納される。その支持
台は、ブームの先端側を支持すべく旋回台から離れて
(例えば、旋回台が車体後部に取り付けられている場合
には、車体前部に)設けられることが多い。By the way, except during work, the boom is stored on a boom support provided on the body of the work vehicle. The support base is often provided apart from the swivel base (for example, in the front part of the vehicle body when the swivel base is attached to the rear part of the vehicle body) to support the tip end side of the boom.
この支持台上にブームを格納するときにおいて、作業台
上の作業者にとっては支持台が作業台もしくはブームの
死角に入ってしまうことから、また、旋回台上の作業者
にとっては支持台とブームの位置関係が把握しにくいこ
とから、ブームを迅速、確実にブーム支持台上に位置さ
せるのは困難であった。When the boom is stored on this support base, the support base may enter the blind spot of the work base or the boom for the worker on the work base, and the support base and the boom for the worker on the swivel base. It was difficult to quickly and surely position the boom on the boom support because it was difficult to understand the positional relationship between the booms.
そこで、従来は、例えば、電気的な検出器により旋回台
の旋回角を検出し、その検出角が、ブームが支持台上に

ブ等を切換ええて、旋回台を駆動する旋回モータ等への
作動油の供給を遮断することにより旋回台の旋回作動を
停止させるといった方法が採られていた。Therefore, conventionally, for example, an electric detector detects a turning angle of a swivel base, and when the detected angle reaches an angle at which the boom is positioned on a support base, an electromagnetic signal is used to switch an electromagnetic valve or the like. Also, a method has been adopted in which the turning operation of the swivel base is stopped by cutting off the supply of hydraulic oil to the swivel motor or the like that drives the swivel base.

り面倒である。(Problems to be solved by the invention) However, in the electric control method as described above,
Since the configuration is complicated, there is a high possibility that troubles such as disconnection and short circuit of the electric circuit are likely to occur. In addition, there is a problem that the boom may be displaced from the support base and stopped due to a detection error of the detector. In this case, the operator needs to finely adjust the turning position, which is troublesome.
以上の問題に鑑み、本考案では、機械的に作業装置の旋
回作動を停止させて格納する作業装置の旋回自動格納装
置を提供することを目的としている。In view of the above problems, it is an object of the present invention to provide an automatic swing storage device for a working device that mechanically stops the swing operation of the working device and stores the working device.

Configuration of the Invention (Means for Solving the Problem) In order to achieve the above object, in the present invention, a recess is provided on the swivel surface of the swivel base, and at the time of storage operation, the swivel face is arranged so as to face the swirl circumference including the recess. By urging the installed post member to project in the direction of the swivel surface, and when the working device swivels to a predetermined storage position, the post member projects toward the recess and is fitted into the recess. The working device is configured to be locked and held in a predetermined storage position.

作業装置の旋回作動がロックされる。(Operation) In such a swing automatic storage device, when the storage operation is performed by the worker, the post member is urged by the urging means such as the solenoid in the lock mechanism so as to project in the direction of the rotation surface. The tip of the post member is pressed against the swivel surface while the working device is located at a position other than the predetermined storage position. At the same time when the working device is located at the predetermined storage position, the post member faces the recess and fits into the recess. In this way, the turning operation of the working device is locked.

ーム5の左右揺動を抑えている。A swivel base 3 is attached to the rear part of the vehicle body 2 of the aerial work vehicle 1, and the swivel base 3 is freely rotatable by a rotary operation of a hydraulic swing motor (not shown). A base end of a boom 5 is pivotally attached to the swivel base 3 via a stand member 4. The boom 5 can be raised and lowered and expanded and contracted by the expansion and contraction operation of the lift cylinder 6 and the like. A bucket 7 for mounting a worker is attached to the tip of the boom 5. It should be noted that this drawing shows a storage state of a working device including a swivel base 3, a boom 5 and a work base 6, and the boom 6 is supported by a boom support base 8 provided at a front portion of the vehicle body 2. . This boom support base 8 not only supports the boom 5 from below, but also prevents the boom 5 from falling from the top of the support base 8 by suppressing the left and right swing of the boom 5 with both end surfaces arranged substantially in the width of the boom. There is.

ている。The swiveling automatic storage mechanism 10 includes an insertion hole (recess) 11 and a lock mechanism 12. The insertion hole 11 is formed so as to penetrate from the swivel upper surface 3 of the swivel base 3 to the swivel lower surface 3b. In this example, the insertion position of the insertion hole 11 is the boom 5
However, the position is not limited to this and may be an arbitrary position. The lock mechanism 12 includes a post member 21 and a solenoid 22. The post member 21 has an insertion hole 11
It is arranged so as to face the turning circumference including. In addition,
The tip of the post member 21 is formed in a spherical shape or a roller shape. A solenoid 22 is attached to surround the post member 21. When the solenoid 22 is not excited, the post member 21 is pushed downward by the urging force of the spring 21b attached to the lower end of the post member 21 via the flange 21, and maintains the retracted state. When the solenoid 22 is excited, the post member 21 is pushed upward by the exciting force. The solenoid 22 is a storage switch.
23, and further, the storage switch 23 is connected to the power source B.
次に、本旋回自動格納装置10の作動について説明する。Next, the operation of the automatic turning storage device 10 will be described.

状態を維持し、旋回台11は自由に旋回作動する。During normal work, the storage switch 23 is turned off and the solenoid 22 is de-energized. Therefore, the post member 21 maintains the retracted state by the downward biasing force of the spring 21b, and the swivel base 11 freely swivels.

回作動がロックされ、ブーム5は確実に支持台8上に停
止する。In the storage operation, first, the storage switch 23 is turned on. As a result, an electric signal is sent from the power source B to excite the solenoid 22. This exciting force exceeds the biasing force of the spring 21b and pushes up the post member 21. When the boom 5 is located other than above the support base 8, the tip of the post member 21 abuts on the swivel lower surface 3b and does not project further. When the boom 5 is located above the support base 8, the insertion hole 11 is located at a position facing the post member 21, and at the same time, the post member 21 whose protrusion has been suppressed so far is projected and fitted into the insertion hole 11. To do. In this way, the swivel operation of the swivel base 3 is locked with respect to the vehicle body 2, and the boom 5 reliably stops on the support base 8.

Therefore, the swivel base 3 can be freely swung again. Further, in this example, the insertion hole 11 is used as the recess, but a notch provided in the center direction from the outer edge of the swivel base 3 or a non-through hole may be used.

As described above, the use of the automatic swivel storage device for the working device according to the present invention allows the post member to project and fit into the recess when the working device is located at the predetermined storage position, and the post members are engaged with each other. Since the swinging operation of the working device is locked, the working device can be reliably stopped without shifting from the predetermined storage position, although the construction is very simple.
