[0002] In most firefighting and flood control operations, the laying and retrieval of hoses still relies heavily on manual labor, which is extremely physically demanding. Currently, some auxiliary tools have emerged on the market to assist workers in laying and retrieving hoses. For example, Chinese Patent CN201810694936.7 discloses a hose laying and retrieval device. The device features a winding mechanism and a self-locking clamping mechanism on its frame assembly. The distance between the clamps can be adjusted by changing the left and right clamping arms of the self-locking clamping mechanism to accommodate quick-connect couplings of different diameters. These quick-connect couplings are used to connect hoses of different diameters. However, in this patent's solution, the device clamps the hose connectors from both sides using the clamps of the clamping mechanism, making the placement and removal of the hose roll still not very convenient.

Detailed Implementation

[0038] The following are specific embodiments of this application, described in conjunction with the accompanying drawings, to further illustrate the technical solutions of this application. However, this application is not limited to these embodiments. In the following description, specific details such as particular configurations and components are provided merely to aid in a comprehensive understanding of the embodiments of this application. Therefore, those skilled in the art should understand that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of this application. Furthermore, for clarity and brevity, descriptions of known functions and structures have been omitted.

[0039] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0040] This application provides a hose storage device that allows for convenient loading and unloading of hose rolls, making operation more convenient. A detailed description is provided below with reference to the accompanying drawings.

[0041] refer to Figures 1-6The hose collection device includes a frame 100, a winding assembly 200, a drive assembly 300, and limiting components. The winding assembly 200 includes a winding spindle 30 and a connector seat 90. The connector seat 90 is mounted on the winding spindle 30 and rotates with it, and is used to fix the hose connector 80. The drive assembly 300 is arranged at one or both ends of the winding spindle 30 and is mounted on the frame 100. It includes a drive shaft 60 and a power input source 70, which is connected to the drive shaft 60 and can drive the drive shaft 60 to rotate. The drive shaft 60 has a drive groove 61 with a lateral opening at one end near the winding spindle 30. The end of the winding spindle 30 can be inserted into or removed from the drive groove 61 from the opening side along the radial direction of the drive shaft 60. The drive shaft 60 and the winding spindle 30 placed in the drive groove 61 form a power connection, driving the winding spindle 30 to rotate together. The limiting component is used to limit the winding spindle 30 placed in the drive groove 61 to prevent the end of the winding spindle 30 from separating from the drive groove 61 from the opening side, or to remove the limiting component.

[0042] Specifically, when using the hose collection device to retrieve the hose, firstly, the hose connector 80 is fixed to the connector seat 90. Then, the drive assembly 300 drives the winding assembly 200 to rotate forward, continuously winding the hose onto the winding assembly 200 until a hose roll is formed. When using the hose collection device to release the hose, the drive assembly 300 drives the winding assembly 200 to rotate in the opposite direction, continuously releasing the hose roll from the winding assembly 200. After the hose is completely released, finally, the hose connector 80 is removed from the connector seat 90.

[0043] In this embodiment, the winding assembly 200 can be separated from the drive assembly 300, so different winding assemblies 200 can be used to wind and unwind different hoses. One set of winding assemblies 200 corresponds to one hose roll, and only the corresponding winding assembly 200 needs to be replaced when winding and unwinding different hose rolls.

[0044] like Figure 3 As shown, in one specific embodiment, a drive assembly 300 is arranged at each end of the winding spindle 30. The drive assemblies 300 on both sides are connected to the two ends of the winding spindle 30, and can drive the winding spindle 30 to rotate simultaneously from both sides.

[0045] refer to Figure 5The drive assembly 300 includes a drive shaft 60 and a power input source 70. The drive shaft 60 is used to power the winding spindle 30 to drive the winding spindle 30 to rotate. The power input source 70 is used to provide driving power to the drive shaft 60. In one specific embodiment, the power input source 70 includes a first power input source 71 and a second power input source 72. The first power input source 71 is composed of a manual input element, and the second power input source 72 is composed of an electric input element. The winding spindle 30 can be driven independently by the electric input element. By driving the winding spindle 30 electrically, it can complete the winding and unwinding of the water hose, which can reduce the labor intensity of the operator. The winding spindle 30 can also be driven by the manual input element. Manually driving the winding spindle 30 allows for more precise operation and can temporarily replace the electric input element when it is not working. Both the first power input source 71 and the second power input source 72 can independently drive the drive shaft 60 to rotate. The operator can choose to use the first power input source 71 or the second power input source 72 as needed. In one specific embodiment, see detailed reference. Figure 5 The first power input source 71 is specifically a rotary handle, through which driving force is input manually. In one specific embodiment, the second power input source 72 is specifically a motor.

[0046] refer to Figure 5 and Figure 6 The drive assembly 300 also includes a first drive gear 711 and a second drive gear 721. The first drive gear 711 is poweredly connected to a manual input element, and the second drive gear 721 is poweredly connected to an electric input element. A driven gear 62 is provided on the drive shaft 60, and the driven gear 62 meshes with both the first drive gear 711 and the second drive gear 721. Figure 5 As shown, the first power input source 71 is a rotary handle connected to the first driving gear 711. Operating the rotary handle directly drives the first driving gear 711 to rotate. The second power input source 72 is a motor, and the second driving gear 721 is mounted on the output shaft of the motor. The motor can directly drive the second driving gear 721 to rotate. Here, the first driving gear 711 and the second driving gear 721 mesh with the driven gear 62 respectively. Therefore, both the first driving gear 711 and the second driving gear 721 can independently drive the driven gear 62, transmitting power to the drive shaft 60 through the driven gear 62.

[0047] In addition, other types of transmission components can be integrated into the drive assembly 300 to independently transmit the power from the first power input source 71 and the second power input source 72 to the drive shaft 60, such as transmission belts and transmission chains, which will not be described in detail here.

[0048] refer to Figure 6In this embodiment of the application, the drive shaft 60 is provided with a drive groove 61 with a lateral opening at one end near the winding spindle 30. The end of the winding spindle 30 can be placed into or taken out of the drive groove 61 from the opening side of the drive groove 61 along the radial direction of the drive shaft 60. The drive shaft 60 and the winding spindle 30 placed in its drive groove 61 form a power connection and can drive the winding spindle 30 to rotate together.

[0049] Furthermore, the drive shaft 60 and the winding spindle 30, which is placed in its drive groove 61, form a power connection through a form fit. When using a hose reeling device to retrieve the hose, the winding spindle 30 of the winding assembly 200 is inserted into the drive groove 61 from the opening side along the radial direction of the drive shaft 60. Due to shape constraints, the end of the winding spindle 30 engages with the drive groove 61 of the drive shaft 60 to form a power connection. The structure provided in this application achieves a quick power connection between the winding assembly 200 and the drive assembly 300, making it easier to install and remove the winding assembly 200 for use with different hoses. In this application, simply placing the end of the winding spindle 30 into the drive groove 61 of the drive shaft 60 is sufficient to engage the winding assembly 200 and the drive assembly 300, thereby driving the winding assembly 200 to rotate through the drive assembly 300, thus realizing the unwinding and rewinding of the hose.

[0050] It should be understood that the end of the winding spindle 30 and the drive groove 61 of the drive shaft 60 transmit power through shape constraints. In other words, when the end of the winding spindle 30 is placed into the drive groove 61 of the drive shaft 60, they cannot rotate freely relative to each other due to shape constraints.

[0051] Further reference Figure 7 and Figure 10 In one specific embodiment of this application, the drive groove 61 is provided with a first sidewall 611, a second sidewall 612, and an arc-shaped sidewall 613. The first sidewall 611 and the second sidewall 612 are located on opposite sides, and the arc-shaped sidewall 613 is located at the bottom of the drive groove 61, connecting the first sidewall 611 and the second sidewall 612. The first sidewall 611 and the second sidewall 612 are planar sidewalls, and the end shape of the winding spindle 30 is adapted to the drive groove 61. Figure 7 As shown, the first sidewall 611, the second sidewall 612, and the arc-shaped sidewall 613 form a roughly U-shaped groove structure, namely the drive groove 61. Figure 10 As shown, the end of the winding spindle 30 is located in the drive groove 61 of the drive shaft 60, and the shape of the end of the winding spindle 30 is adapted to the shape of the drive groove 61. The two cannot rotate freely relative to each other. Therefore, when the drive shaft 60 outputs power, the winding spindle 30 can rotate synchronously.

[0052] like Figure 3 and Figure 4As shown, in one embodiment of this application, a limiting hole 34 is provided on the end face of the winding spindle 30. The limiting component is a limiting pin 400 sleeved inside the drive shaft 60. The limiting pin 400 can be adjusted in position along the axial direction of the drive shaft 60 to insert into or retract from the limiting hole 34 on the winding spindle 30 located in the drive groove 61. In one embodiment, the limiting pin 400 is connected to a rotation operating component for manually turning the limiting pin 400.

[0053] like Figure 4 As shown, the limiting pin 400 is sleeved inside the drive shaft 60 and can move axially along the drive shaft 60 to insert into or retract from the limiting hole 34 on the winding spindle 30 located in the drive groove 61. Figure 3 As shown, the end of the winding spindle 30 is located within the drive groove 61 of the drive shaft 60. The limiting pin 400 is inserted forward into the limiting hole 34 on the end face of the winding spindle 30. In this state, the winding spindle 30 is restricted within the drive groove 61 of the drive shaft 60 and cannot disengage radially. When it is necessary to remove the winding spindle 30 from the drive groove 61 of the drive shaft 60, the limiting pin 400 can be adjusted to exit the limiting hole 34 on the end face of the winding spindle 30, thus removing the limiting pin. In one embodiment, a threaded engagement is provided between the limiting pin 400 and the drive shaft 60, and the axial position of the limiting pin 400 is adjusted by the threaded engagement.

[0054] In one embodiment of this application, a guide disk 10 is also arranged on the frame 100. The guide disk 10 surrounds the outer periphery of the end of the drive shaft 60 near the winding spindle 30. A radial guide groove is provided on the guide disk 10 for the end of the winding spindle 30 to pass through. When the radial guide groove is aligned with the opening of the drive groove 61, the end of the winding spindle 30 is guided to enter and exit the drive groove 61.

[0055] Further reference Figures 7-10 The guide disc 10 includes a left limiting portion 11 located on the left side and a right limiting portion 12 located on the right side. The left limiting portion 11 and the right limiting portion 12 together surround the outer periphery of the drive shaft 60, and there is a gap between the left limiting portion 11 and the right limiting portion 12 in both vertical positions to form an upper radial guide groove 13a located on the upper side and a lower radial guide groove 13b located on the lower side, respectively. When the upper radial guide groove 13a is aligned with the opening of the drive groove 61, it can guide the end of the winding spindle 30 to fall into the drive groove 61. When the lower radial guide groove 13b is aligned with the opening of the drive groove 61, it can guide the end of the winding spindle 30 to fall out of the drive groove 61.

[0056] Specifically, the drive shaft 60 can be rotated to align the opening of the drive groove 61 with the upper radial guide groove 13a located on the upper side or the lower radial guide groove 13b located on the lower side. For example... Figure 8As shown, the opening of the drive groove 61 of the drive shaft 60 is aligned with the upper radial guide groove 13a. At this time, the end of the winding spindle 30 can fall into the drive groove 61 through the upper radial guide groove 13a. After the end of the winding spindle 30 falls into the drive groove 61, the limiting pin 400 can be operated to be inserted forward into the limiting hole 34 on the end face of the winding spindle 30 to prevent the winding spindle 30 from disengaging from the drive groove 61 through the upper radial guide groove 13a or the lower radial guide groove 13b during rotation, so as to form a stable connection relationship, such as... Figure 10 As shown.

[0057] When it is necessary to remove the winding spindle 30 from the drive groove 61 of the drive shaft 60, adjust the limit pin 400 to exit the limit hole 34 on the end face of the winding spindle 30, and remove the limit. Figure 9 As shown, after the limiting pin 400 is removed, the opening of the drive groove 61 of the drive shaft 60 is aligned with the lower radial guide groove 13b. At this time, the end of the winding spindle 30 can fall out of the drive groove 61 through the lower radial guide groove 13b and disengage from the drive groove 61.

[0058] It should be understood that the upper radial guide groove 13a is located on the upper side, and the end of the winding spindle 30 can fall into the drive groove 61 under the action of gravity through the upper radial guide groove 13a. The lower radial guide groove 13b is located on the lower side, and the end of the winding spindle 30 can fall out of the drive groove 61 under the action of gravity through the lower radial guide groove 13b and detach from the drive groove 61. The winding spindle 30 can enter and exit the drive groove 61 by gravity, which is faster and less strenuous in operation.

[0059] Further reference Figure 7 In this embodiment, the radial guide groove is configured in an expanding shape that opens to both sides on one side near the inner ring of the guide disk 10 and / or on one side near the outer ring of the guide disk 10. Here, configuring the outer ring of the radial guide groove in an expanding shape makes alignment easier and facilitates guiding the end of the winding spindle 30 in and out.

[0060] In this embodiment, a walking device 20 for movement is also disposed on the frame 100. (See reference...) Figure 1 and Figure 2 The walking device 20 consists of wheels, which move the hose reeling device by rotating. When reeling in the hose, the hose reeling device can be moved towards the hose to avoid dragging it.

[0061] In the above technical solutions, the winding assembly can wind the hose by rotation, and the drive assembly is used to drive the winding spindle to rotate, thereby enabling the winding assembly to wind and unwind the hose. The winding spindle is placed in the drive groove to form a power connection with the drive shaft and is limited by the limiting component, forming a stable drive connection. The hose winding device provided in this application allows for convenient loading and unloading of hose rolls, making operation more convenient.

[0062] In the technical solution of this application, the winding assembly 200 and the drive shaft are connected by a quick connection, and the winding assembly 200 can clamp water hose connectors of different specifications, thereby winding and storing water hoses of different specifications.

[0063] refer to Figures 11-16 In this embodiment, the winding assembly 200 includes a winding spindle 30, a first limiting component 40, and a second limiting component 50. The winding spindle 30 is rotatable, and the first limiting component 40 and the second limiting component 50 are arranged on the winding spindle 30 and can rotate with it, respectively, to limit and clamp the hose connector 80 from the left and right sides. The first limiting component 40 and / or the second limiting component 50 can be adjusted along the axial direction of the winding spindle 30 to change the distance between them, thereby adjusting the clamping width to clamp hose connectors 80 of different sizes. The first limiting component 40 and the second limiting component 50 installed on the winding spindle 30 correspond to a connector seat 90, used to install and fix the hose connector 80.

[0064] like Figure 11 As shown, the hose connector 80 is clamped and limited from the left and right sides by a first limiting component 40 and a second limiting component 50. The distance between the first limiting component 40 and the second limiting component 50 is adjustable. In the first embodiment, one of the first limiting component 40 and the second limiting component 50 is fixed to the winding spindle 30, while the other can be adjusted in position along the axial direction of the winding spindle 30. In the second embodiment, both the first limiting component 40 and the second limiting component 50 can be adjusted in position along the axial direction of the winding spindle 30. Both embodiments allow for adjustment of the distance between the first limiting component 40 and the second limiting component 50.

[0065] Specifically, when winding up the hose, firstly, the distance between the first limiting member 40 and the second limiting member 50 is adjusted to be large enough to accommodate the hose connector 80. Then, as... Figure 12 As shown, the hose connector 80 is placed between the first limiting member 40 and the second limiting member 50, and the positions of the first limiting member 40 and / or the second limiting member 50 are adjusted so that the first limiting member 40 and the second limiting member 50 clamp and limit the hose connector 80, as shown in the clamping state. Figure 11 As shown. After clamping the hose connector 80, the drive assembly 300 drives the winding spindle 30 to rotate and wind the hose around the hose connector 80.

[0066] Specifically, when releasing the hose, firstly, the distance between the first limiting member 40 and the second limiting member 50 is adjusted to be large enough to accommodate the wound hose. Next, the wound hose is placed between the first limiting member 40 and the second limiting member 50, and the positions of the first limiting member 40 and / or the second limiting member 50 are adjusted so that the first limiting member 40 and the second limiting member 50 clamp and limit the hose connector 80. After clamping the hose connector 80, the drive assembly 300 drives the winding spindle 30 to rotate and release the hose. Finally, the positions of the first limiting member 40 and / or the second limiting member 50 are adjusted to release the hose connector.

[0067] It should be understood that adjusting the position of the first limiting component 40 and / or the second limiting component 50 can be done by adjusting the axial position of one of the limiting components or by adjusting the axial position of both limiting components.

[0068] Furthermore, the first limiting component 40 and / or the second limiting component 50 are position-adjusted by threaded transmission. Threaded transmission can be achieved by setting a transmission thread on the winding spindle 30, or by setting a separate lead screw for threaded transmission.

[0069] In one embodiment of this application, as Figure 11 and Figure 16 As shown, the winding spindle 30 has a first length section 31, a second length section 32, and a third length section 33 located between the first length section 31 and the second length section 32. The first length section 31 and the second length section 32 are provided with threads. (Reference) Figures 11-14 The first limiting component 40 includes a first limiting block 41 and a first threaded sleeve 42. The first threaded sleeve 42 is disposed on the first length section 31 of the winding spindle 30 and is threadedly engaged with the winding spindle 30. The first limiting block 41 is arranged on the third length section 33 of the winding spindle 30 and can slide along the winding spindle 30. The second limiting component 50 includes a second limiting block 51 and a second threaded sleeve 52. The second threaded sleeve 52 is disposed on the second length section 32 of the winding spindle 30 and is threadedly engaged with the winding spindle 30. The second limiting block 51 is arranged on the third length section 33 of the winding spindle 30 and can slide along the winding spindle 30. The first limiting block 41 is located on the side near the first threaded sleeve 42, and the second limiting block 51 is located on the side near the second threaded sleeve 52. The first threaded sleeve 42 abuts against the first limiting block 41 by adjusting its position with the threaded transmission of the winding spindle 30, and the second threaded sleeve 52 abuts against the second limiting block 51 by adjusting its position with the threaded transmission of the winding spindle 30, so that the first limiting block 41 and the second limiting block 51 respectively limit and clamp the hose connector 80 from the left and right sides.

[0070] In this embodiment, threads for transmission are machined on the first length section 31 and the second length section 32 of the winding spindle 30. On the first length section 31, the first threaded sleeve 42 forms a threaded engagement with the winding spindle 30. On the second length section 32, the second threaded sleeve 52 forms a threaded engagement with the winding spindle 30. Therefore, the axial position can be changed by rotating the first threaded sleeve 42 and the second threaded sleeve 52.

[0071] like Figure 11 As shown, the first limiting component 40 includes a first limiting block 41 and a first threaded sleeve 42, located on the left side of the hose connector 80. The first threaded sleeve 42 is used to press against the first limiting block 41 to the right, causing the first limiting block 41 to press against the hose connector 80 to the right. The second limiting component 50 includes a second limiting block 51 and a second threaded sleeve 52, located on the right side of the hose connector 80. The second threaded sleeve 52 is used to press against the second limiting block 51 to the left, causing the second limiting block 51 to press against the hose connector 80 to the left. Thus, under the combined action of the first threaded sleeve 42 and the second threaded sleeve 52, the first limiting block 41 and the second limiting block 51 press against the hose connector 80 from both sides. When the hose connector 80 is located between the first limiting block 41 and the second limiting block 51, the distance between the first limiting block 41 and the second limiting block 51 can be changed by adjusting the first threaded sleeve 42 and the second threaded sleeve 52 to clamp or release the hose connector 80.

[0072] In one embodiment of this application, the cross-sectional shape of the winding spindle 30 is set to a non-circular shape in the third length interval 33, and it passes through through holes with the same cross-sectional shape on the first limiting block 41 and the second limiting block 51, so that the first limiting block 41 and the second limiting block 51 form a non-rotatable sliding fit with the winding spindle 30. It should be understood that the cross-sectional shape of the winding spindle 30 is set to a non-circular shape here, and the cross-sectional shapes of the first limiting block 41 and the second limiting block 51 are adapted. The non-circular cross-section cannot generate relative rotation when the shaft and hole are fitted, and the shape fit between the first limiting block 41, the second limiting block 51 and the winding spindle 30 can restrict the rotation of the first limiting block 41 and the second limiting block 51 relative to the winding spindle 30. Under this setting, the first limiting block 41 and the second limiting block 51 can only slide. When adjusting the position of the first limiting block 41 and the second limiting block 51, the first limiting block 41 and the second limiting block 51 will not rotate freely, making operation more convenient and eliminating the need to control the angle.

[0073] It should be understood that a non-circular cross section cannot generate relative rotation when the shaft and hole are fitted. Therefore, it is only required here that the through holes on the first limiting block 41 and the second limiting block 51 and the cross section profile of the winding spindle 30 be set to non-circular shapes, such as hexagons, quadrilaterals, etc.

[0074] like Figure 16As shown, in one specific embodiment, a planar structure 331 is machined along the axial direction on the winding spindle 30 to form a non-circular shape. Further, a planar structure 331 is machined at symmetrical positions on both sides of the winding spindle 30. Here, machining the planar structure 331 on the winding spindle 30 enables the cross-section to form a non-circular shape.

[0075] like Figures 13-15 As shown, both the first limiting block 41 and the second limiting block 51 are provided with limiting grooves 44 / 54 for locking the hose connector 80. The limiting grooves 44 / 54 are adapted to the edge of the hose connector 80, enabling them to lock in place. The left edge of the hose connector 80 is locked in the limiting groove 44 of the first limiting block 41, and the right edge of the hose connector 80 is locked in the limiting groove 54 of the second limiting block 51. The edges of the hose connector 80 are secured within the limiting grooves, facilitating stable locking by the first limiting block 41 and the second limiting block 51.

[0076] In one embodiment of this application, a first baffle 43 is installed on the first limiting block 41, and a second baffle 53 is installed on the second limiting block 51. The space between the first baffle 43 and the second baffle 53 is used to accommodate the water hose wound around the outer circumference of the winding spindle 30. The first baffle 43 and the second baffle 53 are used to limit the water hose and reduce excessive axial displacement during the winding and unwinding of the water hose. Both the first baffle 43 and the second baffle 53 can be installed and fixed in a detachable manner. Specifically, the first baffle 43 can be fixed to the first limiting block 41 with screws, and the second baffle 53 can be fixed to the second limiting block 51 with screws.

[0077] Furthermore, the first baffle 43 is detachably installed on the first limiting block 41 near the first threaded sleeve 42, and the second baffle 53 is detachably installed on the second limiting block 51 near the second threaded sleeve 52.

[0078] In another embodiment of this application, the first limiting member and / or the second limiting member are slidable on the winding spindle. The first and second limiting members are connected by a lead screw, and at least one limiting member has a threaded engagement with the lead screw. The distance between the first and second limiting members is adjusted by the threaded transmission with the lead screw. In this structure, the winding spindle serves as a guide, directing the first and / or second limiting members to slide axially, and the threaded transmission between the lead screw and the first and / or second limiting members serves as a drive.

[0079] It should be understood that, in the first and second limiting components, one can be fixed and the other can slide, or both can be slideable. The lead screw can be threaded into one of the first and second limiting components, or it can be threaded into both simultaneously.

[0080] In one embodiment of this application, the lead screw is provided with a first thread and a second thread. The first thread cooperates with the first limiting member 40, and the second thread cooperates with the second limiting member 50. The first thread and the second thread have opposite directions of rotation. Thus, when the lead screw rotates, the first limiting member 40 and the second limiting member 50 can move in opposite directions, thereby increasing or decreasing the distance between the first limiting member 40 and the second limiting member 50.

[0081] The winding assembly provided in this application clamps the hose connector by arranging a first limiting component and a second limiting component on a rotatable winding spindle. Furthermore, by adjusting the distance between the first and second limiting components, hose connectors of different specifications can be clamped, thereby accommodating hoses of different specifications. Therefore, the technical solution provided in this application can be conveniently used for winding hoses of different specifications.
