[0034] See also Figure 1 The present embodiment discloses an automatic folding device for a fire hose, comprising a fire cabinet 1 and a horizontal stacking mechanism 2 and a clamping mechanism 3 arranged in the fire cabinet. A stacking platform 11 is arranged on the fire cabinet 1, two sets of clamping mechanisms 3 are symmetrically arranged at both ends of the stacking platform 11, and the horizontal stacking mechanism 2 is arranged between the clamping mechanisms 3.

[0035] The fire cabinet 1 is provided with a water inlet 101 and a water outlet 102 along a diagonal direction, and the height of the water outlet 102 is higher than that of the water inlet 101 , so that the fire hose 4 is stacked upward on the stacking platform along an S-shaped path near the water inlet 101 .

[0036] See also Figure 2The horizontal stacking mechanism 2 includes a vertical moving module 21, a horizontal moving module 22, a push rod fixing seat 23, and a first electric push rod 24. The vertical moving module 21 is arranged on the fire cabinet 1. The output end of the vertical moving module 21 is connected to the horizontal moving module 22, so that the horizontal moving module 22 can be driven to move vertically linearly on the vertical moving module 21. The output end of the horizontal moving module 22 is connected to the push rod fixing seat 23, so that the push rod fixing seat 23 can be driven to move horizontally back and forth on the horizontal moving module 22, thereby driving the first electric push rod 24 on the horizontal moving module 22 to move vertically. The first electric push rod 24 is arranged on the push rod fixing seat 23. Both ends of the horizontal moving module 21 are also connected to the clamping mechanism 3.

[0037] Specifically, the vertical movable module 21 includes a vertical support seat 211, a vertical drive component 212, a vertical screw transmission component 213, and a movable fixed plate 214. The vertical support seat 211 is fixed on the fire cabinet 1, and the vertical drive component 212 is fixed on the vertical support seat 211, and the output end is connected to the vertical screw transmission component 213 arranged on the vertical support seat 211, and the movable end of the vertical screw transmission component 213 is connected to the movable fixed plate 214, and the horizontal movable module 22 is fixed on the movable fixed plate 214, driving the vertical drive component 212, so that the vertical screw transmission component 213 drives the movable fixed plate 214 to move vertically, thereby driving the first electric push rod 24 on the horizontal movable module 22 to move vertically.

[0038] In this embodiment, the vertical drive component 212 is a vertical drive motor.

[0039] The horizontal moving module 22 includes a horizontal support seat 221, a horizontal driving component 222, and a horizontal screw transmission component 223. The horizontal support seat 221 is fixed on the movable fixed plate 214, and the horizontal driving component 222 is arranged on the horizontal support seat 221. The output end of the horizontal driving component 222 is connected to the horizontal screw transmission component 223 arranged on the horizontal support seat 221. The push rod fixed seat 23 is fixed on the output end of the horizontal screw transmission component 223. The horizontal driving component 222 is driven, so that the horizontal screw transmission component 223 drives the push rod fixed seat 23 to move horizontally on the horizontal support seat 221, and then drives the first electric push rod 24 to move horizontally; the two ends of the horizontal support seat 221 are also respectively connected to the clamping mechanism 3.

[0040] In this embodiment, the horizontal drive component 222 includes a horizontal drive motor 2221 and a synchronous belt transmission component 2222. The horizontal drive motor 2221 and the synchronous belt transmission component 2222 are both fixed on the horizontal support seat 221. One end of the synchronous belt transmission component 2222 is connected to the horizontal drive motor 2221, and the other end is connected to the horizontal screw transmission component 223.

[0041] See also Figure 3 and Figure 4 The clamping mechanism 3 includes a vertical slide rail 31, a sliding seat 32, a second electric push rod 33, a fixing plate 34, a clamping seat 35, a rotating shaft 36, a fixing screw 37, a nut 38 and a compression spring 39. The vertical slide rail 31 is fixed on the fire cabinet 1. The sliding seat 32 can be vertically slidably arranged on the vertical slide rail 31 and connected to the horizontal support seat 221. The vertical movement of the horizontal support seat 221 drives the sliding seat to move vertically on the vertical slide rail 31. The second The fixed end of the electric push rod 33 is hinged on the sliding seat 32, and the output end is connected to the fixed plate 34. The clamping seat 35 is rotatably set on the sliding seat 32 through the rotating shaft 36. A fixing screw 37 is set on the fixed plate 34. One end of the clamping seat 35 can be slidably sleeved on the fixing screw 37 and limited by a nut 38. A compression spring 39 is sleeved on the fixing screw 37 between the clamping seat 35 and the fixed plate 34, and the compression spring 39 is always in a compressed state.

[0042] The clamping seat 35 includes a driving portion 351 and a clamping portion 352 . The driving portion 351 is sleeved with the fixing screw 37 , and the clamping portion 352 is used to clamp the fire hose 4 .

[0043] Specifically, the second electric push rod 33 is extended to drive the fixed plate 34 to move downward and then drive the driving part 351 to rotate downward around the rotating shaft 36, so that the clamping part 352 rotates upward around the rotating shaft 36 to provide stacking space for the fire hose 4; when a layer of fire hose 4 is stacked, the second electric push rod 33 is contracted to drive the fixed plate 34 to move upward and then drive the driving part 351 to rotate upward around the rotating shaft 36, so that the clamping part 352 rotates downward around the rotating shaft 36, and then the fire hose 4 on the stacking platform 11 is clamped, and the next layer of fire hose 4 is stacked.

[0044] When the horizontal support seat 221 moves vertically upward, it drives the sliding seat 32 to move vertically on the vertical slide rail 31, and then drives the second electric push rod 33 and the sliding seat 32 to move upward. Since a compression spring 39 that is always in a compressed state is sleeved on the fixed screw 37 between the clamping seat 35 and the fixed plate 34, the clamping part 352 will always be pressed on the fire hose 4 when the sliding seat 32 moves upward.

[0045] For further information, see Figure 5 The clamping portion 352 is U-shaped, one end of the opening end of the clamping portion 352 is connected to the rotating shaft 36, and the other end is a clamping end head away from the rotating shaft 36. The clamping end head and the middle connection of the clamping portion 352 are concavely arranged, so that the fire hose 4 fits on the clamping portion 352 and there is a gap 301 between the clamping end head and the fire hose 4, ensuring that the first electric push rod 24 can be inserted into the gap 301, thereby realizing the stacking of the fire hose 4.

[0046] The working principle of this embodiment is as follows: when the fire hose 4 is stacked without water, the vertical drive assembly 212 is first driven, so that the vertical screw transmission assembly 213 drives the movable fixed plate 214 to move vertically, and then drives the first electric push rod 24 and the sliding seat 32 on the horizontal moving module 22 to move vertically downward to the stacking platform 11, such as Figure 6 As shown; since the height of the water outlet 102 is higher than the height of the water inlet 101 and is arranged in the diagonal direction, a part of the fire hose 4 is attached to the stacking platform 11 before stacking begins, and then the second electric push rod 33 near the position is driven to contract, driving the fixing plate 34 to move up and then driving the driving part 351 to rotate upward around the rotating shaft 36, so that the pressing part 352 rotates downward around the rotating shaft 36, thereby pressing the fire hose 4 on the stacking platform 11, and then driving the first electric push rod 24 to extend, and then The horizontal driving assembly 222 is driven, so that the horizontal screw transmission assembly 223 drives the push rod fixing seat 23 to move horizontally on the horizontal support seat 221, thereby driving the first electric push rod 24 to move horizontally. The fire hose 4 follows the trajectory of the first electric push rod 24 under the action of the horizontal movement to stack the first layer of fire hoses, and then drives the second electric push rod 33 on the other side to contract, so that the pressing part 352 rotates downward around the rotating shaft 36, thereby pressing the fire hose 4 on the stacking platform 11. Figure 7 As shown, after clamping, the clamping mechanism 3 on the other side is released, and then the first electric push rod 24 is driven to retract, so that the first electric push rod 24 is driven to be pulled out from the folding part of the fire hose 4, and then the vertical driving assembly 212 is driven, so that the vertical screw transmission assembly 213 drives the movable fixed plate 214 to move vertically upward, thereby driving the first electric push rod 24 and the sliding seat 32 to move vertically upward. When the sliding seat 32 moves upward, since the fixed screw 37 between the clamping seat 35 and the fixed plate 34 is provided with a compression spring 39 that is always in a compressed state, when the sliding seat 32 moves upward, the clamping part 352 will always be pressed on the fire hose 4 to prevent the fire hose 4 from being stacked and deformed, and then the first electric push rod 24 is driven to extend and insert into the gap 301 between the fire hose 4 and the clamping part 352, as shown in FIG. Figure 8 As shown, the horizontal drive assembly 222 is then driven to drive the first electric push rod 24 to move horizontally to achieve the stacking of the second layer of fire hoses, as shown in FIG. Fig. 9 Repeat the above steps so that the fire hose 4 is stacked upward along the S-shaped path on the stacking platform 11 until the fire hose 4 is folded, as shown Fig.10 shown.

[0047] In this embodiment, the fire hose 4 is stacked on the stacking platform 11 by driving the horizontal moving module 22 to drive the first electric push rod 24 to move back and forth horizontally. During the stacking process, the fire hose 4 is clamped and fixed by the clamping mechanisms at both ends of the stacking platform 11 to prevent the fire hose 4 from deforming when stacked. The stacking process does not require manual operation, and automatic stacking is achieved, thereby improving the stacking efficiency of the fire hose 4.
