Description

  The present invention relates to a fire hose winder capable of automatically winding a discharged fire hose while pushing it with a hand cart.

  When a fire-fighting hose that has already been drained is rolled up without using tools, it is rolled up on the ground, but the fire-fighting hose that has already been drained is heavy and contains residual water. In addition to the fact that it is carried out from the middle waist, it requires a lot of labor, and there are problems such as rubbing on the ground and adhesion of dust and the like.

  In order to reduce labor, various winding tools have been developed. These winding tools include a mobile type that winds up a fire hose while moving on the ground, and a stationary type that winds up by installing on the ground. As a movable type, for example, a fire hose winding device comprising a cylindrical body (winding drum) that rotates in only one direction on the ground and an operation handle for supporting the cylindrical body (Patent Document 1) And a wheelbarrow fire hose winding device in which the axle is fixed to the lower end of the frame having a substantially inverted U-shape and the moving wheel is mounted on the end of the axle protruding from the outer surface of the frame. In addition, a guide roller that is rotatably fitted on the axle, a support stand that is individually fixed to the opposite vertical frame portion with a wider interval than the width of the hose, and a rotary support that can be freely attached to and detached from these support stands. Winding supported freely Winder fire hose with a handle and the winding plate (see Patent Document 2) are disclosed.

  In addition, as a stationary type, the swinging seat is pivotally supported on the pedestal via the swinging shaft, and the swinging seat is provided so as to be rotatable around the horizontal axis of the swinging shaft. A pair of left and right guide portions for guiding the hose are provided on each of the rear portions, and a spring is interposed between the pedestal and the swing seat to urge the swing seat so that the front side is inclined downward, and the rear portion of the base A fire hose take-up device (see Patent Document 3) is disclosed in which a take-up shaft support frame is erected and a take-up tool for winding the hose on the take-up shaft support frame is detachably mounted. .

  However, the fire hose winding device described in Patent Document 1 does not use a winding tool because the hose is wound while the cylinder (winding drum) is rolled on the ground by pushing the operation handle. Although the labor is reduced compared to the above, it does not solve the problem that dust is easily attached to or scratched on the hose, and the hoisting device for a fire hose described in Patent Document 2 pushes the hand handle part. However, there is a problem that a double work that must be taken up by turning the take-up handle is performed at the same time, and the fire hose take-up device described in Patent Document 3 has a hose that moves on the ground as it takes up. Since it moves, there is a problem that the hose rubs on the ground or dust or the like adheres. An object of the present invention is to provide a fire hose winder made in view of these problems, and to achieve the object.

  In order to achieve the above object, the present invention provides a fire hose winder having means as described below, that is, a large frame is provided on both the left and right sides of the front part of the base frame base, and the left and right sides of the rear part. This is a hand cart-type hose winder that is provided with a small wheel and is pulled by a tension adjustment member so that it is tilted slightly backward above the base frame base, and a support column is provided obliquely and a hand handle is provided at the upper end. A take-up reel for winding the hose is configured to be driven to rotate by the rotation of the large wheel so as to wind up the hose.

  A support block is provided on the support column which is obliquely provided by being pulled by the tension adjusting member so that it is tilted slightly rearward above the base frame base, and the shaft to which the take-up reel is attached is rotatably supported by the bearing block. The driven pulley is attached to the shaft, the driving pulley is attached to the axle of the large wheel provided on the left and right sides of the front part of the base frame base, and the belt is put on the driving pulley and the driven pulley to rotate the large wheel. Thus, the take-up reel is driven to rotate.

  The take-up reel for winding the hose is configured to be driven to rotate via a clutch that is transmitted only by the rotation of the large wheel when the push handle is pushed and moved forward, and the push handle is pulled to the rear. The rotation of the large wheel when moving it was not transmitted.

  Also, a handwheel handle is attached to the other end of the shaft to which the take-up reel is attached, and a clutch that is transmitted only by the rotation of the large wheel when the hand handle is pushed forward and moved forward between the handwheel handle and the take-up reel. By interposing the driven pulley, the rotation of the large wheel when the push handle is pulled and moved backward is prevented from being transmitted to the take-up reel, and the hose starts to bite into the take-up reel. It is now possible to wind with a handwheel to improve it.

  As described in the above means, the present invention provides large wheels on the left and right sides of the front part of the base frame base, and provides small wheels on the left and right sides of the rear part, and tilts it slightly rearward above the base frame base. As described above, a hand carriage type hose winder provided with a support column obliquely and provided with a push handle at the upper end is pulled by a tension adjusting member, and a take-up reel for winding the hose is provided on the large wheel. It is a fire hose winder that is configured to be driven by rotation to wind up the hose. By simply pushing the hand handle and moving it forward, the hose is naturally wound up, greatly reducing the labor required for winding. it can.

  In addition, since winding is performed while moving forward, if the winding end of the hose is held at a certain height, the hose can be wound without coming into contact with the ground, rubbing on the ground, and dust or the like being attached. It can be wound up without doing.

  Since it is a handcart type with wheels arranged at four places on the front, back, left, and right of the base frame, the hose can be wound up while moving forward in a stable state.

  The best mode for carrying out the present invention will be described below in detail with reference to the drawings illustrating embodiments.

FIG. 1 is a perspective view showing an embodiment of the present invention. As shown in the drawing, the present invention provides large wheels 2 and 2 on the left and right sides of the front portion of the base frame base 1 and small wheels 3 and 3 on the left and right sides of the rear portion. It is a hand carriage type hose winder that is pulled by the tension adjusting member 4a so as to be tilted backward, provided with the support column 4 at an angle, and provided with the push handles 5 and 5 at the upper end, for winding the hose. A drive pulley 8 attached to the axle 7 of the large wheels 2 and 2 and a follower coaxially attached to the take-up reel 6 so that the take-up reel 6 is rotationally driven by the rotation of the large wheels 2 and 2. A belt 10 is stretched around a pulley 9. Since the drive pulley 8 is attached, the front part is made up of large wheels 2 and 2.
Various means for transmitting the rotation of the large wheels 2 and 2 to the take-up reel 6 are conceivable and are not necessarily limited to the means shown in this embodiment.

  In the state where the belt 10 is properly stretched by being pulled by the tension adjusting member 4a so as to be slightly tilted rearward above the base frame base 1, the lower end portion of the column 4 is fixed by the shaft bolt 11 and the nut 11a and reinforced. Supported by the plate 12, the support column 4 is fixed in an oblique state. By tilting the column 4 obliquely backward, the center of gravity can be stably and easily pushed to push the push handles 5 and 5 provided at the upper end of the column 4 forward.

  The support block 4 provided above the base frame base 1 as described above is provided with a bearing block 13, which is attached to the front surface of the support column 4 and wound around one end as shown in FIG. A shaft 14 to which the take-up reel 6 is attached is rotatably supported by bearings 15, 15, and a handwheel handle 16 is attached to the other end of the shaft 14.

  A driven pulley 9 is rotatably fitted to the shaft 14, and is connected to a clutch 17 by a connecting pin 9a. The clutch 17 is connected to a shaft in a clutch body 17A as shown in FIG. 14 includes a claw wheel 17B fixed by a key member 14a, a claw 17D pivotally supported by a pin 17C on the clutch body 17A, and a push rod 17F that presses the back of the claw 17D with a spring 17E interposed therebetween. The toe of the claw wheel 17B is engaged with the tooth part of the claw wheel 17B, and the toe of the claw wheel 17D bites into the tooth part of the claw wheel wheel 17B and is locked by the rotation of the arrow of the clutch 17 itself (direction B). In the rotation of the arrow (b), the claw tip of the claw 17D is pushed by the inclined surface of the tooth portion of the claw wheel 17B, and the lock is released so that the spring 17E is contracted by the push rod 17F.

  The fact that the clutch 17 itself is locked by the rotation in the direction of the arrow (b) means that the driven pulley 9 connected to the clutch 17 by the connecting pin 9a is also locked to the rotation in the same direction, via the belt 10 and the driving pulley 8. Therefore, the rotation of the large wheels 2 and 2 in the same direction (the direction in which they move forward) is transmitted, and the shaft 14 is unlocked by the rotation of the arrow (b). The hand handle 16 attached to the end can be freely rotated in the direction of the arrow (b), and the take-up reel 6 can be rotated by the hand handle 16 to wind the hose in the same direction.

  The take-up reel 6 includes a disc 6A attached and fixed to one end of a shaft 14, a bar 6B attached to the disc in a cross shape, a ring 6C that supports an end of the bar 6B, and a disc It consists of winding rods 6D and 6E that are slightly decentered from the center of 6A and project, and the winding rod is folded by inserting a folded portion of a hose that is folded in half at an approximately middle portion.

  A guide stand 18 is provided in front of the take-up reel 6 as shown in FIG. 1 for guiding the hose without misalignment. The guide stand guides both sides of the hose. 18A and a guide roller 18B for guiding the lower surface.

  Next, winding the fire hose according to the present invention as described above will be described with reference to FIG. 4 showing a winding example. First, as shown in FIG. The hose S is guided by the guide rollers 18 </ b> A and 18 </ b> B, and the bent portion is inserted into the winding rods 6 </ b> D and 6 </ b> E of the winding reel 6.

  Next, the handwheel handle 16 is rotated about one turn in the direction of arrow A to start winding, and the hose bite is improved, and then moved forward (in the direction of arrow B) as shown in FIG. Thus, the large wheel 2 rotates in the direction of arrow C, the take-up reel 6 rotates in the direction of arrow A, and the fire hose S is naturally wound. When the winding is finished, the winding rods 6D and 6E of the winding reel 6 are extracted.

  The present invention may be used for winding a long hose other than a fire hose, a belt-like sheet or a belt.
