| PURPOSE: To exchange cutting means composed of a plurality of segments as they are left as they are brought to the state of operation. CONSTITUTION: The tool contains a carrier means in which segments 22 can be charged for carrying the segments 22 to the ground drill 12 or them from the ground drill 12. The tool 20 can be operated so that the tool 20 relatively slides the segments 22 when the tool 20 is passed through a predetermined position in the ground drill 12. One end sections of the segments 22 are projected in the lateral direction of the tool 20 and engaged with a seating means 30, and held at the positions of cutting. COPYRIGHT: (C)1996,JPO | ||||||

| PURPOSE: To attain smooth seating by installing a circumferential seating means to the interior wall of a tubular member and mounting a surface formed so that a cutting means is slid to the tubular member in response to the lifting and lowering of the drill at the position of cutting to the seating means. CONSTITUTION: Bit segments 22 are installed to a specified carrying tool and lifted and lowered in the drill, and the lowering of the bits 22 is prevented when the steps 90 of each bit 22 are engaged with a latch dog 32 mounted on the tubular drive sub-assembly 18. An insert 24 extends the bits 22 to the outside in the radial direction, and positions each bit 22 in each recess 58. The insert 24 lowers the bits 22 up to the position of mounting held among the bits and the assembly 18, and locks the bits 22 in the periphery of the assembly 18. When bit crowns 70 are brought into contact with the bottom sections of the bits in the case of cutting, the bits 22 are retracted, and the surfaces 86, 112, 114 of the bits 22 are supported by the fixed surface of the assembly 18. Accordingly, when the bits are exchanged at the position of cutting, the bits can be seated surely. COPYRIGHT: (C)1996,JPO | ||||||

| PURPOSE:To perform simple, reliable, and rapid excavation of a vertical hole, a horizontal hole, or an oblique hole. CONSTITUTION:A hammering means 2 is coupled to the outside part of a handle body 1, an operating body 3 is mounted on the other part of the handle body 1, and a holding body 4 is attached to one side of the operating body 3. A pair of excavating bodies 5 and 5 to perform hammering and opening and closing operation through transmission to the outside part of the holding part 4 from the operating body 3 are axially rotatably mounted. This constitution relieves the work burden of a worker, ensures safety of a work, and achieves shortening of a term of works and sharp saving of a term of works. | ||||||

| PURPOSE: To mount and demount a bit by disposing an insert into a ground drill and moving a cutting means between the position of installation, where the cutting means is held by the insert, and the position of recovery, where the insert is retracted for releasing the cutting means, at the position of cutting. CONSTITUTION: When bit segments 22 are exchanged, a tool 20 in a recovery mode is lowered into the drill 12, and introduced into the insert 24 and a recovery latch dog 154 is engaged. When the tool 20 is lifted slightly by a wire line 256, the insert 24 is retracted by the dog 154, and slid in a drive sub-assembly 18 while the bit segments 22 are released and clamped and shrunk by an elastic band 198. The tool 20 is further pulled up, and engagement with the insert 24 is released and made to reach a land ring 252. A mounting latch dog 138 and the dog 154 are compressed, the tool 20 is passed through the ring 252 and pulled up onto a ground surface, and the segments 22 are exchanged. Accordingly, bits and reamers for the ground drill can be mounted and demounted as they are left as they are positioned at the place of operation. COPYRIGHT: (C)1996,JPO | ||||||

| (57)【要約】 収納可能なドリルビット装置（１０）は、地中ドリル（１２）の下端部に連結されるようになされた駆動副組立体（１８）と、この駆動副組立体（１８）にドリルビットセグメント（２２）を装着し、また駆動副組立体からセグメントを回収するための工具（２０）と、ビットセグメント（２２）を駆動副組立体（１８）の端部に選択的にロックし、またビットセグメントを解放させるためのインサート（２４）を含んでいる。 複数の凹部（５８）が駆動副組立体（１８）の一端部で内周壁面に沿って形成され、また座着手段（３２）が凹部（５８）の上流側の内壁面に沿って形成される。 座着手段（３２）と凹部（５８）との間の内壁面の面積部分は一連のテーパーを付された平坦面で付形される。 工具（２０）はスライド可能なクレードル（１７６）を含み、クレードルは装着および回収時にビットセグメント（２２）が保持される一端部から延在される。 ビットセグメント（２２）は弾性バンド（１９８）でクレードルのまわりの所定位置に保持される。 インサート（２４）は、ビットセグメントが駆動副組立体（１８）にロックされたときにビットセグメント（２２）の上に位置される一連のキー溝（２１８）を一端部に備えている。 インサート（２４）は、駆動副組立体（１８）の内部に常に保持される。 ビットセグメント（２２）は工具（２０）により駆動副組立体（１８）へと運ばれ、インサート（２４）で所定位置に位置決めされる。 工具（２０）は次ぎに抜き出されて、ドリル（１２）が通常のように作動される。 ビットセグメント（２２）を回収するために、工具（２０）はドリルの中に再度下ろされた後、インサート（２４）を回収するために必要とされる短い距離を引き上げられて、ビットセグメント（２２）がクレードル（１７６）上に緊縮できるようになされるとともに、ドリル（１２）から回収できるようになされる。 | ||||||

| PURPOSE: To safely and sanitarily perform work within a short time without staining a worker by performing a series of works cutting the road surface around a manhole lid and simultaneously drawing up the manhole lid and the cut road surface from a drive position by remote operation. CONSTITUTION: A cutter 10 is set to the annular cutting groove 90 of a manhole 92 to be engaged with a manhole plate 14 and key grooves 48a-48n are aligned with lever grip parts 38-38n. A key groove disk 16 is allowed to fall along a drive shaft 20 to be positioned at the part under the horizontal surface 94 of the manhole 92 to be arranged in a concrete part 96. The lever grips 38a-38n, the drive shaft 20, a cutter ring part 12 and the key groove disk 16 are revolved at this position. By this constitution, outside clean out grooves 40a-40n and inside clean out inclined parts 34a-34n feed waste refuse or rubbish on the surfaces thereof in order to effectively cut a black top 100.
