Device for taking up fire-fighting hose and method for taking up fire-fighting hose

摘要

A device for taking up a fire-fighting hose, allowing the user to quickly and reliably take up the hose with a small force in an upright posture and capable of accurately taking up the hose both in a single layer and in double layers. Wheels (2) are rotatably supported at the lower part of a frame body (1), and a handle (5) is provided to the upper part of the frame body (1). The frame body (1) can be moved by rotating the wheels (2) by pushing or pulling the handle (5). A rotatable reel (3) on which hose (H) is wound is provided to the frame body (1), a power transmitting circulation member (4) is passed over the rotating shaft (33) of the reel (3) and the rotation support shaft (21) of the wheels (2) to enable the reel (3) to rotate in association with the rotation of the wheels (2). A core member (3A) for a single-layer winding and a core member (3B) for double-layer winding, which are interchangeable, are provided to the reel (3), and either the core member (3A) for a single-layer winding or the core member (3B) for double-layer winding can be removably affixed to a rotating shaft section (30a) of a base plate (30) of the reel (3).

主权项

1. A method of taking up a fire-fighting hose, in which a long hose including couplers respectively arranged at both a leading end portion and a trailing end portion thereof is taken up and restored, the method comprising:
pivotably supporting a pair of wheels at ends of a rotational support shaft at a lower portion of a frame unit, the wheels respectively comprising a free wheel rotatably and pivotably supported and an associative wheel coupled to a transmission circulating member so that rotational torque of the wheels can be transmitted, the free wheel being free to rotate relative to the rotational support shaft; pushing and drawing a handle arranged at an upper portion of the frame unit so that the wheels are rotated and the frame unit can be moved; providing, to the frame unit, a rotatable reel around which the hose is rolled up; looping the transmission circulating member around a rotary shaft of the reel and the rotational support shaft of the associative wheel, the reel being rotatable in association with the rotation of the associative wheel; removably fixing one of a single-layer-roll core and a double-layer-roll core to a rotary-shaft portion of a base plate of the reel, the single-layer-roll core and the double-layer-roll core being replaceable with each other on the rotary-shaft portion of the base plate of the reel; when the single-layer roll core is removably fixed to the rotary-shaft portion of the base plate of the reel, rotating the reel so that the hose can be rolled up around the single-layer-roll core, with one of the couplers arranged at the end portions of the hose being a central axis, the one of the couplers being pinched by a holding member provided to the single-layer-roll core and capable of pinching the one of the couplers; when the single-layer roll core is removably fixed to the rotary-shaft portion of the base plate of the reel, rotating the reel under a state in which a fold formed by doubling over the hose is hooked to a hook bar so that the hose can be rolled up around the double-layer-roll core while being looped around a projecting shaft and the hook bar, the projecting shaft being provided to project from the double-layer-roll core, the hook bar being provided near and in parallel with the projecting shaft; and providing an extended guide plate to extend from the base plate of the reel so that the hose can be rolled up by passing a hose guide arranged on a front side of the frame unit and then being led to the reel, with a side edge of the hose being held in abutment with a surface of the extended guide plate, tensioning the hose in the front of the take-up device after the hose has been taken up by a predetermined length and an outer circumference of a taken-up part of the hose has become larger than unit circumferences of the wheels; lifting off the associative wheel under a state in which the opposite free wheel rotatably and pivotably supported by the rotational support shaft is grounded; temporarily stopping take-up operation performed by the reel after moving forward the take-up device in a lift-off state so that a tensioned state of the hose is cancelled; and after the temporarily stopping, grounding the associative wheel and moving forward the take-up device again, to thereby take up the hose.
