Title: Body bending vibration preventing device and installation method thereof
Inventor: SATOU TOMOYUKI
IPC: B61D49/00
Filed: 1990-01-08
Abstract: PURPOSE:To provide a device having an excellent damping performance to body bending vibration and capable of supporting a weight or underfloor equipment even when a spring is broken by interposing a rubber vibration isolator working in the compressing direction under the floor of a rolling stock body to support the weight or underfloor equipment. CONSTITUTION:Four support members 2 formed of inverted L-shaped arm beams are disposed in rectangular positions on the floor lower surface of a rolling stock 1, and rubber vibration isolators 3 are mounted on the horizontal top ends of the members 2, and a weight or underfloor equipment 4 is supported in such a manner that a compressive force acts on the rubber vibration isolators 3. This vibration preventing device uses the rubbers 3 in compressing direction, and when a body primary bending vibration is generated, the weight or underfloor equipment 4 supported by the rubbers 3 acts as a dynamic absorber, and displaces the weight or underfloor equipment 4 reversely to the displacement by the body bending vibration. Hence, a force reversed to the body bending direction is generated to reduce the body bending vibration. When the rubbers 3 are broken, the weight or underfloor equipment is directly supported by the support members, so that its falling can be prevented.

Title: Free-slewing system of oil-pressure shovel
Inventor: MIYAOKA SATOSHI
IPC: E02F3/43
Filed: 1986-01-09
Abstract: PURPOSE:To permit functions matching various kinds of operations to be selected by the same machine by providing an oil path having paired working oil paths connected by a shuttle valve, etc., and a switch valve for the pressure oil-flowing-in and out port of an oil-pressure motor. CONSTITUTION:When the spool of an electromagnetic switch valve 15 is D under a condition that a switch 22 is opened, oil paths 30 and 31 are interrupted and oil paths 6 and 7 form an independent circuit. A slewing operation lever 25 is operated, an oil-pressure motor 5 is normally or reversely turned, and an upper slewing body is stopped by a great deceleration force. When the switch 22 is closed, the valve 15 is switched to E, a slewing free valve 14 is opened, and oil pressure in the oil paths 6 and 7 freely flows into other oil paths through each shuttle valve 13. When the lever 25 is restored to neutral, the motor 5 turns freely by the inertia of the upper slewing body without breaking torque. The efficiency of operations can thus be enhanced according to various conditions.
