Description

Technical Field

[0001] The present invention relates to a fire hose winding device for manually winding a fire hose.

Background Art

[0002] Fire hoses used in fire fighting activities and the like are stored and managed in a state of single winding wound around one end, or double winding wound around a folded part with the hose folded in half.

[0003] However, in a wound fire hose, if the central part of the winding is very tight and tightened, when stored in that state for a long time, damage such as cracks may occur in the fire hose, resulting in poor durability. Also, when winding a fire hose used in a fire fighting activity or the like, since a certain amount of water is inside, the hose is pushed by hand to drain the water inside, which is extremely laborious. Therefore, there has been a demand for a fire hose winding device that can solve these problems.

Summary of the Invention

Problems to be Solved by the Invention

[0004] Therefore, in view of the above circumstances, an object of the present invention is to provide a fire hose winding device that can easily wind a fire hose manually and can suppress a decrease in durability during storage.

Means for Solving the Problems

[0005] In order to solve the above problems, a fire hose winding device according to the present invention is “A fire hose winding device for winding a fire hose, a frame-shaped base frame, a column erected on the base frame, a main shaft rotatably supported near the upper end of the column with its axial direction parallel to the base frame, Extending outward from one end side of the main shaft in parallel with the axial direction, and three winding cores provided at equal angular intervals with respect to the axis of the main shaft, Three cylindrical members covering each of the three winding cores, A rotation operation unit for rotating the main shaft, A plurality of first guide rollers spaced apart in a direction perpendicular to the axial direction with respect to the plurality of winding cores and provided above the plurality of winding cores, A roller support frame that rotatably supports the first guide roller around an axis parallel to the axial direction and is erected on the base frame 、 A rotating wheel that rotates integrally with the main shaft, A lateral displacement prevention mechanism that is attached to the base frame and prevents displacement of the fire hose wound around the core as the main shaft rotates Comprising and the lateral displacement prevention mechanism includes a pair of mounting stays extending from the base frame and spaced apart in a direction parallel to the main shaft, a shaft rotatably attached at both ends to the pair of mounting stays, and a rod-shaped lateral displacement prevention member having a proximal end attached to the shaft, the lateral displacement prevention member extends linearly from the proximal end toward the three cores, curves so as to pass above them near the three cores, and then extends linearly downward, and is provided so as to be able to contact the cylindrical member covering the core from above with a distance slightly longer than the width of the hose body of the fire hose between it and the rotating wheel It is characterized by "".

[0006] According to the fire hose winding device of this configuration, the fire hose can be wound as follows. Specifically, for example, when winding the fire hose in a single layer, the rear end side of the fire hose is hung on the first guide roller and then held by the winding core. In this state, when the rotation operation unit is operated to rotate the main shaft in the winding direction, the fire hose is wound around the three cylindrical members. Along with this, the fire hose is pulled toward the three cylindrical members, and due to the friction with the fire hose, the first guide roller rotates, guiding the movement of the fire hose. Since the first guide roller is provided above the winding core, the fire hose is lifted to a high position first and then wound. As a result, the water inside can be naturally discharged from the front end side by the action of gravity.

[0007] After that, when the winding of the fire hose is completed, stop the rotation of the main shaft, pull the wound fire hose outward in the axial direction of the main shaft, and remove it from the main shaft (winding core) together with the three cylindrical members. Then, when the three cylindrical members are removed from the wound fire hose, the fire hose will be in a single-wound state.

[0008] As described above, according to the fire hose winding device of this configuration, the fire hose can be wound manually. When winding the fire hose, by hanging the fire hose on the first guide roller, the fire hose can be lifted to a high position once, so that the water inside can be discharged by the action of gravity, and different from the prior art, it does not require the labor of squeezing the water by hand. Also, as the water is naturally discharged as the winding progresses and the fire hose becomes lighter, the winding operation of the fire hose can be made easier.

[0009] Also, if there were one or two winding cores, the fire hose would be wound very tightly around the winding core, and it would be difficult to remove the wound fire hose from the winding core. In contrast, in the present invention, since three winding cores (cylindrical members) are used for winding, a space can be left between the winding core and the hose body, and it is possible to alleviate the situation where the central part of the winding of the fire hose becomes very tight. Also, since each of the three winding cores is covered with a cylindrical member, by pulling out the wound fire hose from the winding core together with the three cylindrical members, the wound fire hose can be easily removed from the winding core.

[0010] Furthermore, since the fire hose is wound through the three cylindrical members, when the cylindrical members are removed from the wound fire hose, a gap is created by the amount of the removed cylindrical members, so that the central part of the winding becomes even looser. As a result, compared with the case where the fire hose is stored with the central part of the winding being very tightly tightened, damage such as cracks in the fire hose is less likely to occur, and a decrease in durability can be suppressed.

[0011] Also, the fire hose winding device according to the present invention, in addition to the above configuration, "A plurality of casters attached to the lower end of the base frame, "Further provided" may be a feature.

[0012] According to this configuration, since a plurality of casters are provided, the fire hose reel device can be easily moved, which is convenient for carrying.

[0013] Also, since casters are provided, the fire hose reel device can be moved while winding the fire hose. As a result, when winding a fire hose with water remaining inside, the fire hose that has become heavy due to the water remaining inside can be wound without dragging it, so that wear of the fire hose due to dragging can be avoided, and damage to the fire hose can be suppressed.

[0014] Furthermore, in addition to the above configuration, the fire hose reel device according to the present invention "A second guide roller having a rotation center at a position higher than the height of the main shaft and lower than the rotation center of the first guide roller and rotatably provided around an axis parallel to the axial direction, "Further provided" may be a feature.

[0015] According to this configuration, since the second guide roller is provided at a position lower than the first guide roller, when winding a fire hose that does not have water inside, by hanging it on the second guide roller, compared to the case of hanging it on the first guide roller, the height by which the fire hose is lifted can be reduced, and the fire hose can be wound with a small force.

Effects of the Invention

[0016] As described above, as an effect of the present invention, it is possible to provide a fire hose reel device that can easily wind a fire hose manually and suppress a decrease in durability during storage.

DETAILED DESCRIPTION OF THE INVENTION

[0018] A fire hose reel device 1 according to an embodiment of the present invention will be described in detail with reference to FIGS. 1 to 5. The fire hose reel device 1 of this embodiment is for winding a fire hose 2 (see FIG. 5). The fire hose reel device 1 of this embodiment includes a substantially rectangular frame-shaped base frame 10 in plan view, and casters 11 respectively attached to the four corners of the base frame 10. Two adjacent ones of the four casters 11 are swivel casters 11a, and the remaining two are fixed casters 11b. Hereinafter, the rolling direction of the fixed caster 11b will be referred to as the front-rear direction, the side on which the swivel caster 11a is located in the front-rear direction will be referred to as the front, and the horizontal direction and the direction orthogonal to the front-rear direction will be referred to as the left-right direction.

[0019] The fire hose reel device 1 of this embodiment includes a column 12 erected near the rear portion on one side of the center of the base frame 10 in the left-right direction, a box-shaped axle box 13 attached near the upper end of the column 12, a main shaft 14 passing through the axle box 13 in the left-right direction and rotatably supported by the axle box 13, and a rotary handle 15 attached to one end of the main shaft 14.

[0020] Further, the fire hose winding device 1 includes a rotating wheel 16 attached to an end of the main shaft 14 opposite to the end where the rotating handle 15 is attached, three winding cores 17 extending from the central portion of the rotating wheel 16 parallel to the main shaft 14 and on the side opposite to the rotating handle 15, and three cylindrical members 18 covering each of the three winding cores 17. A gripping member 19 is attached to one end of each cylindrical member 18.

[0021] Furthermore, the fire hose winding device 1 includes a first guide roller 20 having a rotation center at a position in front of and higher than the main shaft 14, a second guide roller 21 having a rotation center at a position not lower than the height of the main shaft 14 and lower than the rotation center of the first guide roller 20, and a roller support frame 22 standing on the front end side of the base frame 10 and rotatably supporting the first guide roller 20 and the second guide roller 21 respectively.

[0022] Also, the fire hose winding device 1 includes a lateral displacement prevention mechanism 23 attached to the base frame 10 to prevent displacement of the fire hose 2 wound around the winding core 17 as the main shaft 14 rotates, and a handle 24 extending outward (forward) from the front end of the base frame 10.

[0023] The base frame 10 includes a pair of vertical frames 10a extending in the front-rear direction, a pair of horizontal frames 10b connecting the two ends of the pair of vertical frames 10a respectively, and an intermediate frame 10c connecting the pair of vertical frames 10a between the pair of horizontal frames 10b. The intermediate frame 10c is provided at a position closer to the rear than the center in the front-rear direction of the pair of vertical frames 10a.

[0024] Also, the base frame 10 includes four auxiliary frames 10d provided so as to protrude outward in the left-right direction at both the front and rear ends of each of the pair of vertical frames 10a. Each auxiliary frame 10d is formed in a right trapezoid shape and is provided such that the sides parallel to each other and the side orthogonal to them are located on the extension line of the horizontal frame 10b. The base frame 10 is formed of a strip-shaped plate material with its front and back surfaces facing horizontally.

[0025] The caster 11 includes two swivel casters 11a and two fixed casters 11b as described above. The swivel casters 11a are respectively attached to the front auxiliary frame 10d in the base frame 10, and the fixed casters 11b are respectively attached to the rear auxiliary frame 10d with the rotation axes parallel to the main shaft 14. The fire hose reel device 1 can be moved by the four casters 11. Note that the casters 11 may be those with stoppers.

[0026] The column 12 is composed of two strip plates that are long in the vertical direction, and the lower ends of each are attached to the rear horizontal frame 10b and the intermediate frame 10c in the base frame 10.

[0027] The axle box 13 is formed in a box shape with a rectangular parallelepiped shape and an open lower surface. A bearing for rotatably supporting the main shaft 14 is provided in this axle box 13. A bearing may be used as the bearing. The main shaft 14 is columnar and long in the left and right directions.

[0028] The rotation handle 15 has a paddle portion 15a with one end fixed to the main shaft 14 and extending in a direction perpendicular to the main shaft 14, and a grip portion 15b extending parallel to the main shaft 14 from the tip of the paddle portion 15a. The length of the rotation radius of the grip portion 15b around the axis of the main shaft 14 of the rotation handle 15 is smaller than the height from the upper end of the base frame 10 to the main shaft 14. Therefore, when the rotation handle 15 is rotated, the grip portion 15b or the like does not contact the base frame 10. In this rotation handle 15, since the paddle portion 15a is integrated with the main shaft 14, the main shaft 14 can be rotated by operating to rotate the grip portion 15b around the axis of the main shaft 14, which corresponds to the rotation operation portion of the present invention.

[0029] The rotating wheel 16 has a hub portion 16a attached to the main shaft 14 and rotating integrally with the main shaft 14, a plurality (here, six) of spoke portions 16b radially extending from the hub portion 16a, and a ring-shaped wheel portion 16c connecting the tips of the plurality of spoke portions 16b. The radius of the wheel portion 16c is substantially the same as the radius of the grip portion 15b of the rotating handle 15. The rotating wheel 16 is provided at the center in the left-right direction with respect to the base frame 10. By rotating the wheel portion 16c, the rotating wheel 16 can rotate the main shaft 14 and corresponds to the rotation operation portion of the present invention. That is, the main shaft 14 can be rotated either by rotating the rotating handle 15 or by rotating the rotating wheel 16.

[0030] As shown in FIG. 4, each of the three spools 17 is cylindrical and is attached to the hub portion 16a of the rotating wheel 16 so as to extend outward from one end of the hub portion 16a. The three spools 17 are provided at equal angular intervals with respect to the axis on the circumference of a predetermined radius centered on the axis of the main shaft 14. Therefore, the three spools 17 form an equilateral triangle. The length of the spool 17 is substantially the same as the width of the fire hose 2.

[0031] The cylindrical member 18 is slightly longer than the length of the spool 17, and its inner diameter is larger than the outer diameter of the spool 17. As shown in FIG. 4, the gripping member 19 is attached to one end of the cylindrical member 18. The gripping member 19 of the present embodiment is formed by making a flexible string-shaped member into a ring shape and is attached in a state of passing through the cylindrical member 18.

[0032] The first guide roller 20 has a rotating shaft 20a having a length slightly longer than the width of the fire hose 2, a pair of disk-shaped side plates 20b attached near both ends of the rotating shaft 20a, and a plurality of connecting rods 20c connecting the pair of side plates 20b and provided at equal intervals on the circumference concentric with the rotating shaft 20a.

[0033] The second guide roller 21 has substantially the same configuration as the first guide roller 20 except for the attached position. That is, a rotating shaft 21a having a length slightly longer than the width of the fire hose 2, a pair of disk-shaped side plates 21b attached near both ends of the rotating shaft 21a, and a plurality of connecting rods 21c that connect the pair of side plates 21b and are provided at equal intervals on the circumference concentric with the rotating shaft 21a. Note that the outer diameter of the second guide roller 21 (side plate 21b) is smaller than the outer diameter of the first guide roller 20 (side plate 20b).

[0034] The roller support frame 22 includes a pair of frame bodies 22a that are separated in the left-right direction and long in the up-down direction. As shown in FIG. 3, the pair of frame bodies 22a each have a pair of first shaft support portions 22b provided at their upper ends, a pair of extension pieces 22c extending rearward from the middle in the up-down direction of each of the pair of frame bodies 22a, and a pair of second shaft support portions 22d provided on each of the extension pieces 22c.

[0035] The lower ends of the pair of frame bodies 22a are each attached to the base frame 10, extend vertically from the base frame 10 to a position higher than the main shaft 14, and then bend rearward and extend to a position higher than the upper end of the rotating wheel 16. The interval in the left-right direction between the pair of frame bodies 22a is wider than the interval between the pair of side plates 20b of the first guide roller 20 and narrower than the length of the rotating shaft 20a. The right frame body 22a of the pair of frame bodies 22a is attached to the front horizontal frame 10b, and the left frame body 22a is attached to the vertical frame 10a. The extension piece 22c is provided at a position at the same height as the main shaft 14 below the bent portion of the frame body 22a.

[0036] The first shaft support portion 22b and the second shaft support portion 22d are each in a groove shape that is notched in a U shape from above, and can respectively insert the rotating shaft 20a of the first guide roller 20 and the rotating shaft 21a of the second guide roller 21.

[0037] The roller support frame 22 can support the first guide roller 20 and the second guide roller 21 rotatably and detachably about an axis parallel to the axis of the main shaft 14 by inserting the rotation axis 20a of the first guide roller 20 and the rotation axis 21a of the second guide roller 21 into the first shaft support 22b and the second shaft support 22d from above. When the first guide roller 20 and the second guide roller 21 are supported by the roller support frame 22, the positions of the first guide roller 20 and the second guide roller 21 in the left - right direction coincide with the positions of the three core tubes 17 in the left - right direction.

[0038] The lateral displacement prevention mechanism 23 includes a pair of mounting stays 23a that extend rearward from the lateral frame 10b on the rear side of the base frame 10 and are spaced apart in the left - right direction, a shaft 23b whose both ends are attached to the pair of mounting stays 23a and extends parallel to the main shaft 14, and a rod - shaped lateral displacement prevention member 23c whose proximal end side is attached to the shaft 23b. The lateral displacement prevention member 23c rotates integrally with the shaft 23b.

[0039] The lateral displacement prevention member 23c has a substantially L - shaped curved form. As shown by the solid line in FIG. 3, when rotated toward the core tube 17 side, it extends linearly from the proximal end near the base frame 10 toward the rear of the three core tubes 17, then curves so as to pass above the three core tubes 17 in the vicinity of the three core tubes 17, and then extends linearly forward and downward.

[0040] When the lateral displacement prevention mechanism 23 is in a state where the lateral displacement prevention member 23c is in contact with the cylindrical member 18 covering the core tube 17, the tip side rather than the curved part acts like a weight and abuts against the cylindrical member 18 from above. The distance between the lateral displacement prevention member 23c and the hub portion 16a is set to be slightly larger than the width of the hose body 2a.

[0041] The handle 24 is formed by bending a long cylindrical or tubular member into a U-shape. The two ends of the U-shaped handle 24 are attached to the front end of the base frame 10 so as to extend obliquely forward and upward from the front end of the base frame 10. The handle 24 is a part to be gripped when manually pulling and advancing the fire hose reel device 1. When the bent part is placed along the waist of the operator, it is easy to pull. Note that the handle 24 may be detachable or foldable with respect to the base frame 10.

[0042] Next, a method of winding the fire hose 2 using the fire hose reel device 1 of the present embodiment will be described with reference to FIG. 5 and the like. Note that in FIG. 5, the gripping member 19 is omitted. Here, the fire hose 2 includes a long tubular hose body 2a, a male fitting 2b attached to one end of the hose body 2a, and a female fitting (not shown) attached to the end of the hose body 2a opposite to the male fitting 2b. A plurality of fire hoses 2 can be connected by a joint between the male fitting 2b and the female fitting. Hereinafter, a case where the fire hose 2 with water remaining inside the hose body 2a is wound in a single layer will be described.

[0043] First, the fire hose reel device 1 is arranged so that the end on the side with the male fitting 2b (hereinafter referred to as the rear end of the fire hose 2) of the unwound fire hose 2 faces the fire hose reel device 1. Since the fire hose reel device 1 is provided with casters 11, it can be easily moved to a desired position and orientation.

[0044] In this state, the lateral displacement prevention member 23c of the lateral displacement prevention mechanism 23 is separated from the winding core 17 (cylindrical member 18). Specifically, as shown by the two-dot chain line in FIG. 3, the distal end side of the lateral displacement prevention member 23c is rotated (rotated in the clockwise direction in the drawing) so as to be located behind the rotating wheel 16.

[0045] Also, each of the three spools 17 is covered with a cylindrical member 18. At this time, the cylindrical member 18 is oriented such that the end opposite to the end where the gripping member 19 is attached faces the hub portion 16a side.

[0046] Then, lift the rear end of the fire hose 2 and place it on the first guide roller 20. Specifically, place the hose body 2a over the connecting rod 20c between the pair of side plates 20b of the first guide roller 20 from above. By lifting the rear end to the height of the first guide roller 20, the water remaining inside the hose body 2a flows to the front end side and is discharged.

[0047] Subsequently, pass the portion of the hose body 2a near the male fitting 2b through between two of the three cylindrical members 18, and then extend it outside through the space between one of them and the remaining cylindrical member 18. At this time, bring the male fitting 2b as close as possible to the cylindrical member 18.

[0048] Then, rotate the lateral displacement prevention member 23c of the lateral displacement prevention mechanism 23 so that it is in contact with the cylindrical member 18. In this state, operate the rotating handle 15 or the rotating wheel 16 to rotate the main shaft 14 in the winding direction. At this time, since water remains inside the hose body 2a and it is heavy, it is easier to perform the rotation operation with the rotating wheel 16 where there is a continuous portion for rotation operation by the wheel portion 16c.

[0049] By means of a rotating operation such as that of the rotating wheel 16, the hose body 2a is wound around the three cylindrical members 18, and as the hose body 2a is pulled toward the three cylindrical members 18, the first guide roller 20 rotates due to the frictional resistance with the hose body 2a. Since the hose body 2a is lifted to the height of the first guide roller 20 at a high position and then wound up, the water in the hose body 2a can be discharged from the front end side as it is wound up. At this time, the fire hose winding device 1 is advanced while winding up the hose body 2a. The fire hose 2 filled with water is heavy and difficult to move. In addition to this, it is not desirable to move it while dragging on the ground. However, since the fire hose winding device 1 is provided with casters 11, the fire hose winding device 1 can be moved.

[0050] Also, since the distance between the lateral displacement prevention member 23c of the lateral displacement prevention mechanism 23 and the hub portion 16a is set to be slightly longer than the width of the hose body 2a, the hose body 2a being wound up is prevented from being displaced by the lateral displacement prevention member 23c and becoming a bamboo shoot shape. Further, since the lateral displacement prevention member 23c also has the effect of imparting rotational resistance to the main shaft 14 via the cylindrical member 18, when the rotational operation of the rotating wheel 16 or the like is weakened or stopped midway, the main shaft 14 is suppressed from rotating in the direction opposite to the winding direction.

[0051] After that, when the hose body 2a is wound up to the female fitting portion, the joint with the male fitting 2b of the subsequent fire hose 2 is disconnected, the rotational operation of the rotating wheel 16 or the like is stopped, and the rotation of the main shaft 14 is stopped. Then, the lateral displacement prevention member 23c is rotated backward so that the lateral displacement prevention member 23c is not in contact with the cylindrical member 18. In this state, the wound hose body 2a is pulled outward in the left - right direction and pulled out from the winding core 17 together with the three cylindrical members 18. Since the inner diameter of the cylindrical member 18 is larger than the outer diameter of the winding core 17 and there is a gap, the operation of pulling out the wound hose body 2a from the winding core 17 is easy.

[0052] When the wound fire hose 2 is removed from the winding core 17 together with the cylindrical member 18, grasp and pull the gripping member 19 provided on each cylindrical member 18 to extract the cylindrical member 18 from the wound hose body 2a. As a result, the fire hose 2 is in a single-wound state. Since a gap is created at the center of the winding by removing the three cylindrical members 18, the hose body 2a at that portion can be shaken by hand to loosen the winding at the center portion.

[0053] When single-winding the fire hose 2 with no water remaining inside the hose body 2a, such as during training, since there is no need to drain the water, the hose body 2a is hung on the lower-positioned second guide roller 21 instead of the higher-positioned first guide roller 20 and wound up. Compared with the case of hanging the hose body 2a on the first guide roller 20 and winding it up, since the height at which the hose body 2a is lifted is lower, the fire hose 2 can be wound up with a small force.

[0054] Also, when double-winding the fire hose 2, the hose body 2a is folded in half at approximately the center in its longitudinal direction, and one cylindrical member 18 is passed through the folded valley portion so that the folded peak portion passes between the three cylindrical members 18. Also, depending on the presence or absence of water remaining inside the hose body 2a, the hose body 2a is placed in a state of being hung on the first guide roller 20 or the second guide roller 21. Then, in that state, by rotating an operation wheel 16 or the like so that the main shaft 14 rotates in the winding direction, the fire hose 2 can be double-wound.

[0055] Thus, according to the fire hose winding device 1 of the present embodiment, the fire hose 2 can be wound manually. Also, when winding the fire hose 2 with water inside, by hanging the hose body 2a on the first guide roller 20, the fire hose 2 is lifted to a high position once and then wound up, so that the water inside can be easily discharged by the action of gravity, and unlike the prior art, no labor is required to push out the water by hand. Also, by naturally discharging the water as the winding progresses, the hose body 2a becomes lighter, making it easier to wind up the fire hose 2.

[0056] Further, according to the present embodiment, since the three core members 17 (cylindrical members 18) are used for winding, it is possible to alleviate that the central portion of the winding of the hose body 2a becomes very tight as compared with the case of using one or two core members, and a space can be left around the core member 17. Further, since each of the three core members 17 is covered with the cylindrical member 18, the wound fire hose 2 can be easily removed from the core member 17 together with the three cylindrical members 18.

[0057] Furthermore, according to the present embodiment, when the cylindrical member 18 is removed from the wound fire hose 2, a gap is created by the amount corresponding to the disappearance of the cylindrical member 18, so that the central portion of the winding becomes looser. As a result, compared with the case where the fire hose is stored in a state where the central portion of the winding is tightly tightened, damage such as cracks is less likely to occur in the fire hose 2, and a decrease in durability can be suppressed.

[0058] Also, according to the present embodiment, since the casters 11 are provided, the fire hose winding device 1 can be moved while winding the fire hose 2. Thereby, when winding the fire hose 2 in which water remains inside the hose body 2a, it is possible to wind the hose body 2a that has become heavy due to the water remaining inside without dragging it, so that abrasion of the fire hose 2 due to dragging can be avoided, and damage to the fire hose 2 can be suppressed.

[0059] Also, according to the present embodiment, since the distance between the lateral displacement prevention member 23c of the lateral displacement prevention mechanism 23 and the hub portion 16a of the rotating wheel 16 is set to be slightly larger than the width of the hose body 2a, during the winding of the fire hose 2, a plurality of spoke portions 16b and the lateral displacement prevention member 23c are positioned on both left and right outer sides of the hose body 2a, and it is possible to prevent the hose body 2a during winding from being displaced in the left-right direction and becoming a bamboo shoot shape, and the fire hose 2 can be wound neatly.

[0060] Further, according to the present embodiment, since two guide rollers with different heights, i.e., the first guide roller 20 and the second guide roller 21, are provided, when the fire hose 2 with water inside is wound up, by hanging it on the first guide roller 20 with a higher height, the water inside can be easily discharged by the action of gravity. On the other hand, when the fire hose 2 without water inside is wound up, by hanging the fire hose 2 on the second guide roller 21 with a lower height, the height by which the fire hose 2 is lifted becomes lower, so that the fire hose 2 can be wound up with a small force.

[0061] Furthermore, according to the present embodiment, since the first guide roller 20 and the second guide roller 21 are each detachably provided with respect to the roller support frame 22, when storing the fire hose winding device 1 in a warehouse or the like, by leaving the first guide roller 20 and the like removed, the fire hose winding device 1 can be prevented from being bulky.

[0062] As described above, the preferred embodiments of the present invention have been described. However, the present invention is not limited to the above embodiments, and various improvements and design changes are possible without departing from the gist of the present invention.

[0063] For example, in the above embodiment, the lateral displacement prevention member 23c is shown to also have the effect of restricting the rotation of the main shaft 14. However, the present invention is not limited thereto, and a configuration including a rotation restricting mechanism 30 as shown in FIG. 6 may be adopted. This rotation restricting mechanism 30 is rotatably attached to the base frame 10 and includes a cam 30a provided so as to be able to contact the wheel portion 16c of the rotating wheel 16, and a handle 30b for rotating the cam 30a. In a state where the cam surface of the cam 30a is not in contact with the wheel portion 16c (see FIG. 6(a)), the rotation restricting mechanism 30 can freely rotate the wheel portion 16c. In a state where the cam 30a is rotated by the handle 30b and the cam surface of the cam 30a is in contact with the wheel portion 16c (see FIG. 6(b)), the rotation of the wheel portion 16c is restricted by the frictional force. Thereby, the rotation of the main shaft 14 can be restricted via the rotating wheel 16.

[0064] Also, as a rotation restricting mechanism different from the above, a ratchet that restricts rotation of the main shaft 14 in the direction opposite to the winding direction may be used. In this case, it is desirable to be able to release the rotation restriction by the ratchet.

[0065] Also, in the above embodiment, the rotation operation unit is shown as including two components, the rotation handle 15 and the rotation wheel 16, but it is not limited to this, and it may include only one of them. Also, a reduction gear may be provided between the rotation operation unit and the main shaft 14. Thereby, the rotation operation unit can be rotated with a light (weak) force. Such a gear and the above-described ratchet can be installed inside the axle box 13.

[0066] Furthermore, in the above embodiment, the one including the second guide roller 21 is shown, but it is not limited to this, and it may not include the second guide roller 21.
