| PROBLEM TO BE SOLVED: To provide a control method of a working module such as a hydraulic grab and a device which excavates a hole and removes obstacles from the hole extremely effectively (effective as hardware, time, and cost) and carry out a plurality of works through the working module. SOLUTION: The rotation of a drill rod 2 is transmitted to a working module 5 through a rotary head housing 17 and a switch housing 15. And a work such as drilling is carried out thereby. The first directional rotation of the drill rod 2 is converted i-times faster or slower (i is the transmission ratio of the gear) than the rod by a gear 7 and transmitted to a hydraulic pump 9 through a trip-free structure 11. And a hydraulic cylinder 6 is driven by the hydraulic pump 9 to give the axial movement to the working module 5. A grab is closed by the axial movement for instance. COPYRIGHT: (C)1998,JPO | ||||||

| The present invention relates to a power transmission unit of an impactor and a hydraulic jet impactor. A rubber seal of hydraulic jet impactor was subject to corrode and so did the hole of a upper splite-flow cap in the past, so that the impactor single-time service life was reduced, and also because of so many parts, the transmission unit had a low efficiency. In order to raise the velocity of drilling well and/or elongate impactor single-time service life, a passage located in a side wall is formed by separating waterproof seal in respect to inner wall of outer sleeve, so that said rubber seal could be omitted, then a anvil of the transmission unit is combined with its lower joint so that impacting power loss is reduced during the transmission. A nozzle of which the material made from is more antifriction than that of splite-flow cap's does is provided in said splite-flow hole. Especially, the nozzle is one of nozzles whose inner diameters are different with each other so that various flow requirements could be met by replacing a nozzle and abrasion of splite-flow hole would be relieved effectively. | ||||||
