摘要： PURPOSE: To provide a fluid pressure reducing device which can make a fluid of constant pressure flow out regardless of pressure fluctuation with a simple structure. CONSTITUTION: A fluid pressure reducing device is constituted by forming a fluid inflow pipe 43 at the upper part of a body 42 of hollow conical shape large in diameter at the upper part and small in diameter at the lower part, along the peripheral tangential direction, and forming a control fluid inflow pipe 45 along a direction intersecting a fluid flowing inside from the fluid inflow pipe 43 while forming a fluid outflow pipe 44 at the lower part of the body 42, along the axial direction.

摘要： PURPOSE:To accurately and efficiently perform operations of extending a piping by allowing a dolly to travel forward in the direction of piping elongation until an end sensor senses the cut end of the already laid piping. CONSTITUTION:An expansion/contraction mechanism 3 is installed ahead of a dolly 2 which travels in the direction of pipe elongation. After separated from the already laid piping Pa, the mechanism 3 is shrunk, and meantime the dolly 2 is advanced in the direction of extending until and end sensor 7 senses the cut end of the old piping Pa. A new piping Pb prepared in the neighborhood of the connecting position is lifted by crane mechanisms 4, 4 down to the connecting position and held in the specified position by gripping mechanisms 5, 5. In this condition, connecting mechanisms 6, 6 are operated to connect the new piping Pb with the old piping Pa. This operating cycle is repeated, and the piping is extended into the specified length.

摘要： PROBLEM TO BE SOLVED: To easily insure a working space inside an excavator at exchange of cutters or maintenance of the interior of the excavator and easily restore the machine to its original state by making the belt conveyor of the excavator movable back and forth. SOLUTION: In a cylindrical excavator main body 1 equipped with a cutter head 2 on the front end part, a belt conveyor 4 extending from the inner part to the rear side is arranged. In this belt conveyor 4, a plurality of part positions 4a-4e are connected together through joint members 5, the last part position 4e is fitted to a slide base 6, movably supported by a frame base 8 on the main body 1 side, and the part positions 4a-4d are slidably supported on a receiving base 10. The slide base 6 is made slidable back and forth by a motor- driven winch 12 through a wire rope 14. Consequently at exchange of cutters 3 or maintenance of the interior of the excavator, the belt conveyor 4 is pulled out rearward, a working space can be insured in the main body 1, and at completing the work they can be easily restotred to the original state.

摘要： PURPOSE:To removably mount a crape-off claw and a bucket for scraping-up to a single working machine. CONSTITUTION:A scraping-off claw 11 is attached to the tip of the swing arm 22 of a working machine through a connection fitment 12. A bucket 10 for scraping-up is removably mounted on the scraping-off claw 11 through a lock device 16 incorporated in the scraping-off claw.

摘要： PURPOSE:To install struts easily in an unmanned manner even in a deep underground section by remotely controlling the struts holding retaining walls on both sides of a shaft from the ground even in water and adjusting and setting the struts. CONSTITUTION:A strut 7 is gripped through a clamp 20 and lowered between the retaining walls 1 of a shaft, and an automatic strut fixture 5 is fixed. The strut 7 is moved forward by the automatic strut fixture 5, and both ends of the strut 7 are fastened to opposed timberings 2. A clamp is opened, the strut 7 is removed, and the automatic strut fixture 5 is pulled up. A series of these operation are remotely operated. Accordingly, the struts can be mounted easily even in a deep underground section, and the operation can be conducted completely in an unmanned manner.
