摘要：本発明は応力波の測定方法と、測定装置と、破岩装置とに関するものである。衝撃装置（7）は衝撃パルスを導波路（21）に与え、導波路では圧縮応力波および反射引張応力が生成され、これらは導波路を伝播する。圧縮応力波は導波路で拡張を、引張応力波は収縮を生じ、この場合、導波路の断面における幾何学的変化を測定することによって導波路の特性を判定してよい。この測定データは破岩装置の制御に利用される。

摘要： PROBLEM TO BE SOLVED: To provide a drive device for a turning tool operating with vibration superimposition by the improvement in a drive shaft, a support bearing for a support sleeve, and a packing in order to prolong the service life of the drive device and especially the tool provided with the drive device. SOLUTION: The drive device for the turning tool operating with vibration superimposition, has a drive casing 11, the support sleeve 15, the drive shaft 13, tool-retaining bodies 16A, 16B, and a vibration-energizing device. The support sleeve 15 is supported within the drive casing 11 with flexible rotation, and the drive shaft 13 is supported within the support sleeve 15 with flexible rotation. The tool-retaining bodies 16A, 16B store a working tool, and the vibration-energizing device generates the lap of vibration of the tool-retaining bodies 16A, 16B. In order to prolong the service life of the drive and especially the tool provided with the drive by simplifying the drive shaft, the support bearing for the support sleeve, and the packing, each vibration-energizing device of the tool-retaining bodies 16A, 16B has at least two intermediate shafts 30. The intermediate shafts 30 are each connected to the tool-retaining bodies 16A, 16B through the medium of one eccentric member 32, and are synchronously driven. COPYRIGHT: (C)2007,JPO&INPIT

摘要： PURPOSE: To enable the substantial shortening of construction hours and the accurate injection of chemicals and mortar, etc., capacitating it to use a long boring rod, while facilitating the positioning of this boring boring in a tunnel. CONSTITUTION: A boring rod 18 is connected to a hollow type drifter 16 via a holding device 19 after piercing through this this drifter 16 in it, whereby a this long boring rod 18 is made usable. In addition, this hollow type drifter 16 is attached to a turnable guide shell 11 and slidden to some extent, and further a turning device 9 of this guide shell 11 is made slidably to a mast 7 being free of elevation and holdable at an optional position respectively, through which the positioning of the boring rod 18 up to a boring position being radial from the tunnel center is facilitated. Moreover, a self-boring lock bolt is used in this boring rod 18, and simultaneously with the end of installation, chemicals and mortar, etc., are made injectable.

摘要： PURPOSE:To improve drilling efficiency by a method wherein a plurality of rotary type drills each provided at a tip part with a hammering device are juxtaposed in an adjoining state and a thrust device to simultaneously advance the drills is installed to a guide cell. CONSTITUTION:A slit drilling device is arranged in a sleeve 10 and the rear part of an excavation bit 11 is hammered. The drilling device is rotated through a rod 20 by a rotating device 35, a hole in a circular shape in cross section is continuously drilled in a rock-bed, and an elongated slit is formed. Constitution of the slit drilling device 1 is such that a plurality of down the hole(DTH) drills 2 are intercoupled in an adjoining state through a fitment 3 and disposed to a guide cell 5. Further, a thrust device 43 to simultaneously advance the drills 2 is arranged to the guide cell 5. The drilling device 1 is loaded on a running vehicle, such as a hydraulic shovel, and a guide rod 31 is inserted in an existing hole. Holes are drilled in succession to form a slit and a bedrock is crushed. This constitution simplifies the structure of a device and performs high-efficient excavation.

摘要： PURPOSE:To reduce operator's fatigue by detecting a defective swing of a rock bed facing machine for drilling with a line bit of a swing plate to indicate it on an indicator or the like and temporarily stop pressurized oil feed for automatic recovery. CONSTITUTION:Holes 15a are drilled in a rock bed 15 by two side drills 9 and while a swing plate 7 is swung horizontally, the rock bed is excavated between the holes 15a which communicate to each other through a slit 15b. Then oil pressure supplied to a swing motor and feed motor in drilling is detected by oil pressure detectors 24, 25 and inputted to a calculation process unit 28 to always judge the occurrence of a defective swing. Next, when the oil pressure is judged to be abnormal, the defective swing is indicated on an indicator 30 from the calculation process unit 28 through a D/A converter 29 and the feed motor 5 is stopped. After the stoppage for a certain time the swing is recovered from the defective one to resume feed.
