[Industrial applications]

 TECHNICAL FIELD The present invention relates to a movable concrete compacting device for compacting concrete that has been driven into a form frame having reinforcing bars.

[0002]

[Prior Art]

 Concrete pouring works include compaction work to compact the poured concrete. The work of compacting this concrete is generally performed by inserting a vibrator into the concrete that has been placed, but this work is mainly performed manually by the operator holding the vibrator.

[0003]

[Problems to be solved by the device]

 The conventional manual compaction work described above is performed on rebars with poor scaffolding, but only on a soft floor, and because it involves heavy vibrators, the working environment is poor. , Has become a considerable amount of hard work. It also causes white wax disease because it supports the vibrator by hand.

In view of the above points, the present invention reduces the manual work in concrete compaction work to facilitate the work, and also prevents white wax disease by releasing the worker from the vibration of the vibrator, Further, the present invention provides a movable concrete compaction device for the purpose of protecting the mechanical device from the vibration of the vibrator and preventing the damage due to the vibration.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention has a structure in which a balancer device is mounted on a moving device, and a vibrator is attached to the arm tip end of the balancer device through a supporting device equipped with a vibration isolation mechanism. ..

In addition, in the supporting device provided with the vibration isolation mechanism, a base provided with a vibrator gripping portion is attached to a frame connected and fixed to an arm tip end by interposing an anti-rubber therebetween. The structure was fixed in contact.

[0007]

[Action]

 After moving to the destination by the moving device, the operator holds the arbitrary part of the tip of the arm of the balancer device to move the vibrator vertically, and inserts the vibrator into the concrete that has been placed. Since the vibrator is attached to the arm of the balancer device, the operator can move the vibrator in the vertical direction with a light force. Also, since the vibrator is attached to the arm tip of the balancer device via the support device equipped with a vibration isolation mechanism, the vibration of the vibrator is absorbed by the vibration isolation mechanism and is not directly transmitted to the arm tip. The hands of an operator who does not receive strong vibration at the arm tip and holds an arbitrary part of the arm tip is protected from the vibration of the vibrator, and the mechanical device is also protected from the vibration.
