[0002] With the increase of urbanization and high-rise buildings, the complexity of firefighting tasks and the requirements for efficiency are constantly increasing. In order to improve the efficiency and quality of firefighting operations and reduce the workload of firefighters, fire hose reel devices have emerged. In the current existing technology, fire hose reel devices generally use manual control to reel in or use sensors to detect the reeling degree of the reel. The former increases the workload and reduces the work efficiency, while the latter increases the cost of the device, complicates the structure of the device, and may result in errors in the number of turns detected. Utility Model Content

[0003] The utility model aims to provide a fire hose reeling device, aiming to solve the technical problems existing in the prior art, such as high production and processing costs of the device, high workload of operators, and low reeling efficiency and quality caused by detection errors.

[0004] In order to solve the above technical problems, the utility model provides a fire hose winding device, comprising: a chassis, on which a driving mechanism, a winding turntable and a number of turns detection mechanism are provided, the winding turntable is rotatably installed on the chassis, the driving mechanism is provided with an output shaft, and the output shaft is connected to the winding turntable; the number of turns detection mechanism includes a counter, a toggle member elastically provided on the counter, and a protrusion provided on the output shaft, the counter is triggered when the toggle member is squeezed, and a roller is rotatably provided at one end of the toggle member, and the protrusion can contact and squeeze the roller.

[0005] The fire hose is wound up by connecting the driving mechanism and the winding turntable, which eliminates manual labor and is beneficial to reducing work intensity and improving winding efficiency. The number of turns detection mechanism is used to directly detect the output end of the driving mechanism, which simplifies the structure of the number of turns detection and reduces the production and processing cost of the winding device. The selection of rollers at the squeezed part of the squeezed protrusion is beneficial to reducing the direct friction between the roller and the protrusion or the output shaft, and reducing possible disturbances. At the same time, the structure of the roller can stably drive the toggle member to trigger the counter for both the forward and reverse rotation of the output shaft, which is beneficial to improving the accuracy of the number of turns detection of the winding and further to improving the winding quality.

[0006] Preferably, the number of turns detection mechanism also includes an auxiliary trigger assembly, which includes a trigger body that is rotatably and elastically mounted on the chassis, and a rotating wheel that is rotatably connected to the trigger body, the protrusion can contact and squeeze the rotating wheel, and the roller abuts against the trigger body.

[0007] When the rotating wheel is squeezed by the protrusion of the output shaft, it drives the trigger body to rotate relative to the chassis. Since the trigger body is in contact with the roller, the trigger body will squeeze the roller more smoothly and stably when rotating. The roller will drive the toggle member to move relative to the counter, thereby triggering the counter. Therefore, the auxiliary trigger component is beneficial to improving the stability of trigger detection and increasing the life of the toggle member. At the same time, the structure of the rotating wheel can also enable the auxiliary trigger component to respond to the forward and reverse rotation of the output shaft, thereby further improving the accuracy of output shaft detection.

[0008] Preferably, the auxiliary trigger assembly further comprises a fixing member fixed to the chassis, the trigger body is elastically connected to the fixing member via an elastic member, and the elastic member pulls the trigger body to make the rotating wheel approach the output shaft.

[0009] The elastic member can make the trigger body reset after being squeezed by the protrusion and rotating, and make the rotating wheel close to the protrusion of the output shaft, which is beneficial to ensure that the rotating wheel on the trigger body can be stably squeezed by the circularly rotating protrusion, driving the trigger body to stably squeeze the roller on the toggle member, thereby improving the counting stability of the toggle member triggering the counter, and further improving the detection accuracy of the circle detection mechanism; the fixing member assists in connecting the elastic member and the trigger body, which is beneficial to the positioning of the elastic member and the trigger body, and makes the installation and disassembly of the elastic member and the trigger body more convenient.

[0010] Preferably, the winding turntable includes a rotating shaft rotatably connected to the chassis, and two turntables fixed on the rotating shaft at intervals, and both turntables are provided with limiting columns, and a belt feed port is formed between the two limiting columns and the rotating shaft.

[0011] The winding turntable has a simple structure, and the operator can easily place the fire hose at the hose inlet, which is conducive to simplifying the structure of the winding device, improving the winding efficiency, and facilitating subsequent maintenance.

[0012] Preferably, a mounting column is provided on the rotating shaft, and the mounting column is located between the two rotating disks.

[0013] On the one hand, the mounting column can make the two turntables more stable, which is beneficial to maintaining the stability of the winding turntable. On the other hand, it can cooperate with the limit column to narrow the belt inlet and limit the deviation of the entrance end of the fire hose, which is beneficial to improving the winding quality.

[0015] A transmission assembly is arranged between the winding turntable and the output shaft, which can improve the stability of the transmission, optimize the structure of the winding device, make the structure more compact and facilitate the installation and layout of the various components. When a favorable transmission ratio is set, the service life of the device can be increased, the transmission efficiency can be improved, and the winding efficiency of the fire hose can be further improved.

[0016] Preferably, a guide assembly is provided on the chassis, and the guide assembly is located next to the winding turntable. The guide assembly includes a fixed roller and a suspended roller. The fixed roller is connected to the chassis, and the suspended roller is connected to the chassis through a cantilever, and the position of the cantilever relative to the chassis is adjustable.

[0017] The guide component can support and guide the fire hose so that the fire hose can accurately enter and be wound around the winding turntable, which is beneficial to improving the winding efficiency and quality of the fire hose; the suspended roller can adjust its relative position with the chassis through the cantilever, and lengthen or shorten the distance between the fixed roller and the suspended roller, and adjust according to the material and length and width of the fire hose, which is beneficial to adapt to different types of fire hoses and improve the expandability of the winding device.

[0018] Preferably, both ends of the fixed roller and both ends of the suspended roller are provided with limiting members.

[0019] The limiter is helpful to limit the displacement of the fire hose relative to the fixed roller or the suspended roller, prevent the fire hose from falling off, and at the same time maintain the consistency of the position entering the winding turntable, which is further helpful to improve the winding quality.

[0020] Preferably, the driving mechanism comprises a rotating driving member arranged on the chassis, and a reducer connected to an output end of the rotating driving member, and the output shaft is the output end of the reducer.

DETAILED DESCRIPTION

[0033] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively with reference to the accompanying drawings. The accompanying drawings provide preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein.

[0034] In the description of the present invention, it should be understood that terms such as "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0035] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0036] In this embodiment, please refer to Figure 1 and Figure 2 As shown, the utility model provides a fire hose 70 winding device, which includes a chassis 10, a driving mechanism 20 arranged inside the chassis 10, a winding turntable 30 rotatably mounted on the chassis 10, and a number of turns detection mechanism 40 arranged on the chassis 10, the driving mechanism 20 is provided with an output shaft 21 extending out of the chassis 10, and the output shaft 21 is connected to the winding turntable 30 through a transmission connection so that the winding turntable 30 winds up the fire hose 70.

[0037] Please refer to Figure 3 The number of revolutions detecting mechanism 40 is used to record the number of revolutions of the output shaft 21, and includes a counter 41 mounted on the chassis 10, a toggle member 42 elastically connected to the counter 41, and a protrusion 43 arranged on the output shaft 21. A rotatable roller 421 is also provided at one end of the toggle member 42, and the roller 421 is adjacent to the output shaft 21. Every time the protrusion 43 rotates one circle with the output shaft 21, it will contact and squeeze the roller 421. After the roller 421 is squeezed, it drives the toggle member 42 to move relative to the counter 41 and triggers the counter 41 to record a number of revolutions. After the protrusion 43 moves away from the roller 421, the toggle member 42 is reset, and the output number of revolutions of the output shaft 21 is recorded in this reciprocating cycle.

[0038] It can be understood that the use of roller 421 can reduce the friction between it and the protrusion 43. At the same time, no matter whether the output shaft 21 rotates forward or reverse, when the protrusion 43 squeezes the roller 421, the toggle member 42 can move normally relative to the counter 41 and trigger the counter 41. Therefore, the roller 421 can also be replaced by a structure such as a ball that can achieve the above functions.

[0039] In this embodiment, please refer to Figure 3 As shown, the lap detection mechanism 40 further includes an auxiliary trigger assembly 44, which is disposed between the protrusion 43 and the roller 421, and is used to assist the protrusion 43 in squeezing the roller 421 and the toggle member 42 to trigger the counter 41. The auxiliary trigger assembly 44 includes a trigger body 442 rotatably connected to the chassis 10, and a rotatable wheel 444 mounted on the trigger body 442. The function of the wheel 444 is similar to that of the roller 421. Each time the protrusion 43 rotates one circle with the output shaft 21, it will contact and squeeze the wheel 444. The wheel 444 drives the trigger body 442 to rotate relative to the chassis 10. Since one side of the trigger body 442 abuts against the roller 421, when the trigger body 442 rotates, it will squeeze the roller 421 and cause the toggle member 42 to move relative to the counter 41, thereby triggering the counter 41 to record a lap.

[0040] In this embodiment, please refer to Figure 3 As shown, the trigger body 442 is an "L"-shaped structure. It can be understood that the shape structure of the trigger body 442, the rotational connection position of the trigger body 442 and the chassis 10, and the position of the rotating wheel 444 on the trigger body 442 can all be changed so as to realize the function of the above-mentioned auxiliary trigger component 44.

[0041] In addition, the rotating wheel 444 can also be replaced by a structure such as a ball that can achieve its function, just like the roller 421.

[0042] Specifically, the auxiliary trigger assembly 44 also includes a fixing member 441 and an elastic member 443 fixed to the chassis 10. One end of the trigger body 442 is elastically connected to the fixing member 441 by the elastic member 443, and the rotating wheel 444 is installed at the other end of the trigger body 442. When the auxiliary trigger assembly 44 is in a balanced state without being squeezed by the protrusion 43, the rotating wheel 444 is close to or abuts against the output shaft 21, and the rotating wheel 444 can be squeezed by the protrusion 43 on the rotating output shaft 21. After the rotating wheel 444 is squeezed by the protrusion 43 and the trigger body 442 rotates, the elastic member 443 can pull the trigger body 442 to reset. It can be understood that the elastic member 443 can be a leaf spring, a coil spring, a rubber belt, or other components that can achieve the above functions.

[0043] In addition, the trigger body 442 may not be rotationally connected to the chassis 10 , but may be rotationally connected to the fixing member 441 . In this case, the fixing member 441 also assumes the positioning function of the entire auxiliary trigger assembly 44 .

[0044] In addition, an elastic member 443 may be sleeved on the rotating connection of the trigger body 442 , and the trigger body 442 may be elastically connected to the chassis 10 or the fixing member 441 through the elastic member 443 , so as to realize the function of resetting the trigger body 442 .

[0045] In this embodiment, please refer to Figure 2 and Figure 4 As shown, the winding turntable 30 includes a rotating shaft 31 and two turntables 32 fixed on the rotating shaft 31 at intervals. The rotating shaft 31 can be rotatably connected to the chassis 10 through the bearing 11 and the bearing seat 12. When the rotating shaft 31 rotates, the two turntables 32 will also rotate. A limit column 321 is provided on each turntable 32. The limit column 321 extends toward the other turntable 32 and forms a clamping port for clamping the fire hose 70 together with the rotating shaft 31.

[0046] In addition, the outer turntable 32 can be disassembled when the winding is completed, which is convenient for taking out the wound fire hose 70; the limiting column 321 can also be one or more, so that the fire hose 70 can be clamped and the fire hose 70 can be normally wound on the winding turntable 30; handles can also be set on the non-opposite surfaces of the two turntables 32, so that the fire hose 70 can be manually wound without using the driving mechanism 20.

[0047] Specifically, a mounting post 33 is fixedly connected to the rotating shaft 31, and the mounting post 33 is located between the two rotating discs 32. The two rotating discs 32 can be bolted to the mounting post 33 to improve the stability of the winding rotating disc 30. At the same time, the mounting post 33 replaces the rotating shaft 31 and forms a clamping opening for clamping the fire hose 70 with the two limiting posts 321, reducing the spacing between the clamping openings to improve the clamping effect.

[0048] More specifically, please refer to Figure 2 The winding turntable 30 is connected to the output shaft 21 through a transmission assembly 50. The transmission assembly 50 includes a driving wheel 51 fixedly mounted on the output shaft 21, a driven wheel 52 fixedly mounted on the rotating shaft 31, and a connecting member (not shown) connecting the driving wheel 51 and the driven wheel 52. In the present embodiment, they are a driving sprocket, a driven sprocket, and a chain, respectively. It can be understood that a gear combination, a pulley and a belt, a gear and a transmission chain, etc. can also be used as the transmission assembly 50 to realize that the output shaft 21 drives the winding turntable 30.

[0049] In addition, the winding turntable 30 can also be directly connected to the output shaft 21 .

[0050] In this embodiment, a guide assembly 60 is further provided next to the winding turntable 30, and the guide assembly 60 includes a fixed roller 61 rotatably connected to the chassis 10, a cantilever 63 arranged on the chassis 10 and capable of adjusting a rotation angle relative to the chassis 10, and a suspended roller 62 arranged on the cantilever 63. The cantilever 63 extends the winding turntable 30 outside the chassis 10, and the suspended roller 62 is arranged at one end of the cantilever 63. The rotation direction of the fixed roller 61 and the suspended roller 62 is consistent with that of the winding turntable 30, and can accurately guide the fire hose 70 to enter and be wound around the winding turntable 30.

[0051] In addition, a plurality of fixed rollers 61 or suspended rollers 62 may be provided.

[0052] It can be understood that the structural shape of the cantilever 63 and the position connected to the chassis 10 are variable, so that the suspended roller 62 can be set next to the winding turntable 30, and the fire hose 70 can be guided by the suspended roller 62 and the fixed roller 61 to enter and wrap around the winding turntable 30.

[0053] Specifically, both ends of the fixed roller 61 and both ends of the suspended roller 62 are provided with limit members 64, which on the one hand provide positioning for the fire hose 70, and on the other hand limit the position of the fire hose 70 from being offset or even falling off.

[0054] In this embodiment, the rotating driving member 22 of the driving mechanism 20 is a motor, and the reducer 23 reduces the output speed of the motor and increases the output end torque of the reducer 23, that is, the torque of the output shaft 21, to provide the driving mechanism 20 with a stronger load capacity.

[0055] In addition, the rotary drive member 22 may also be a speed-adjustable drive source such as an asynchronous motor, a servo motor, a hydraulic or pneumatic motor, etc.

[0056] In this embodiment, a control panel 80 is further provided on the side of the chassis 10. The control panel 80 is electrically connected to the driving mechanism 20 and the number of turns detection mechanism 40. After setting the number of turns required to rotate, the rotation speed and start and stop of the rotating driving member 22 are adjusted by the count fed back by the number of turns detection mechanism 40 to realize the winding of the fire hose 70.

[0057] In addition, the control panel 80 may also be provided with components such as a display screen 71, an emergency stop button 72, a power switch 73, etc., to control the switch, start and stop, and visually adjust the winding process of the fire hose winding device.

[0058] The specific application process of the utility model is as follows:

[0059] Adjust the suspension roller 62 and set the output number of turns required for the type of fire hose 70. Figure 5 The operator winds the unwound fire hose 70 around the suspended roller 62 and the fixed roller 61 in sequence, and then winds one end of the fire hose 70 located on the fixed roller 61 around the clamping port, sets the number of turns parameter, and the driving mechanism 20 drives the winding turntable 30 to start winding. When the number of turns detection mechanism 40 detects the set number of turns, the driving mechanism 20 stops, and the winding of the fire hose 70 is completed.

[0060] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
