[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a breaker device for hard disk excavation.

[0002]

[Prior art]

 Conventionally, for example, when an electric pole is erected, a hydraulic motor with a speed reducer is suspended at the tip of a crane, and the hydraulic motor is operated via a hydraulic pump mounted on a mobile crane to output the output shaft of the hydraulic motor. The means to drive the auger linked to the and to dig a vertical hole in the soil to erect a utility pole is adopted.

However, in the case of a hard disk, it becomes impossible to excavate it with an auger, so that it is unavoidable to excavate the hard disk with a breaker for hard disk excavation.

[0004]

[Problems to be solved by the device]

 However, excavating a hard disk with a breaker puts a heavy burden on the operator.

In particular, the vibration of the breaker causes pollution such as white wax, and further, there are many dangers when working in a place where the scaffolding is poor.

In this invention, the excavation work with the breaker is performed using the crane used in the auger, and the breaker is easily attached to the tip of the boom so that the excavation work can be performed.

[0007]

[Means for Solving Problems]

 In this invention, a hydraulic motor and speed reducer are attached to the boom end of a crane through a swing device, a connecting shaft is detachably connected to the output shaft of the speed reducer, and a side surface of the hydraulic breaker is attached to the lower end of the connecting shaft. Auxiliary shafts installed side by side are detachably connected, and a mounting plate is installed side by side on the outer peripheral surface of the auxiliary shaft via a bracket.The mounting plate is a mounting bolt hole formed on the side surface of the hydraulic breaker. It is intended to provide a breaker device for hard disk excavation configured to be fixed to a hydraulic breaker with a mounting bolt by utilizing.

[Action]

 In this invention, when using a hydraulic breaker on a hard board, a swing device that operates with a hydraulic cylinder is attached to the boom end of the crane, and a speed reducer integrated with the hydraulic motor is attached to the swing device.

Therefore, the swing device can freely displace in the output shaft direction of the speed reducer.

A connecting shaft is connected to the output shaft of the reduction gear, and an auxiliary shaft integrated with a hydraulic breaker is connected to the lower end of the connecting shaft.

Since the auxiliary shaft is integrally mounted on the hydraulic breaker via the bracket and the mounting plate, the auxiliary shaft is connected to the connecting shaft so that the hydraulic breaker is attached to the lower end of the connecting shaft. In such a state, if the swing device is appropriately swung by the operation of the hydraulic cylinder, the hydraulic breaker will be positioned in any direction, for example, in the vertical direction, through the connecting shaft to perform excavation work on the hard disk. Therefore, the hydraulic breaker connected to the boom tip of the crane can be used without any manual labor.

Further, when the hydraulic breaker is removed after the work is completed, it is easy to remove the hydraulic breaker from the auxiliary shaft, the auxiliary shaft from the connecting shaft, and the connecting shaft from the output shaft of the reducer. Can be decomposed into
