Description

Technical Field

[0001] The present invention relates to the technical field of fire-fighting equipment, and in particular to a water hose reeling device. Background Art

[0002] In situations like building fires and forest fires, large fires are difficult and time-consuming to extinguish, leading to significant economic losses. In these situations, ordinary fire trucks, due to their limited water capacity, are unable to carry out prolonged, intensive firefighting operations. This is especially true for fires in oil and gas fields and warehouses. Therefore, to effectively control large fires, multiple fire trucks and high-flow water cannons are required for sustained firefighting operations. Therefore, remote and continuous water supply, directly from the water source and utilizing large-diameter water supply pipelines, is particularly necessary.

[0003] Remote water supply requires large-diameter hoses to be quickly laid between the water source and the fire scene. Hose-laying vehicles are designed to quickly lay the hoses and store them in the vehicle after use. Due to the long distances and heavy weight of the hoses, they are typically retrieved mechanically, eliminating the labor-intensive process.

[0004] In the existing technology, the driving part of the hose reeling device is generally arranged at the front end and the top of the hose laying vehicle, and is generally fixedly installed on the upper end of the hose laying vehicle.

[0035] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, and are not used to limit the scope of the present invention.

[0036] like Figures 1 to 3 As shown, the present invention provides a water hose winding device, including a base 50, a gravity-sensing transmission device 10, a lifting device 20, a guide device 30 and a rotary drive component 40; the rear end of the gravity-sensing transmission device 10 is rotatably installed on the base 50, and the front end of the gravity-sensing device at least partially exceeds the base 50. The rotary drive component 40 is connected between the base 50 and the gravity-sensing transmission device 10 to push the front end of the gravity-sensing transmission device 10 to rotate up or down, and the guide device 30 is installed on the front end of the gravity-sensing transmission device 10 in a liftable manner through the lifting device 20.

[0037] Among them, the gravity sensing transmission device 10 includes a head frame 11, the guiding device 30 includes a guide frame 31, the lifting device 20 includes a support rod assembly 21 and a lifting drive mechanism 22, the support rod assembly 21 includes a first support rod 211 and a second support rod 212, one end of the first support rod 211 and the second support rod 212 is hinged to the guide frame 31, and the other end of the first support rod 211 and the second support rod 212 is hinged to the head frame 11, the length of the first support rod 211 and the second support rod 212 are equal and arranged in parallel, the first support rod 211 is located in front of the second support rod 212, and the lifting drive mechanism 22 is used to drive the first support rod 211 or the second support rod 212 to rotate to drive the guide frame 31 to rise and fall.

[0038] In an embodiment of the present application, the lifting drive mechanism 22 includes a lifting drive member 222 and a connecting rod assembly 221, the connecting rod assembly 221 includes a first connecting rod 223 and a second connecting rod 224, one end of the first connecting rod 223 is hinged between the two ends of the second connecting rod 224, the other end of the first connecting rod 223 is hinged to the head frame 11, the front end of the second connecting rod 224 is hinged to the first support rod 211 or the second support rod 212, the lifting drive member 222 is a first hydraulic cylinder, the cylinder body of the first hydraulic cylinder is rotatably installed on the head frame 11, and the piston shaft of the first hydraulic cylinder is hinged to the rear end of the second connecting rod 224.

[0039] The side of the head frame 11 is fixedly connected to the limiting beam 111, and the limiting beam 111 is located at the front end of the connection between the first support rod 211 and the fixing part. When the first support rod 211 abuts against the limiting beam 111, the guide frame 31 is located at the front end of the head frame 11, and the limiting beam 111 can effectively ensure the rotation angle of the support rod assembly 21.

[0040] Combine Figure 5As shown, the lifting device 20 connects the base 50 and the guide frame 31 through the support rod assembly 21 and the lifting drive mechanism 22, and drives the first support rod 211 or the second support rod 212 to rotate through the lifting drive mechanism 22, thereby realizing the lifting and lowering of the guide frame 31. Since the first support rod 211 and the second support rod 212 are equal in length and are arranged in parallel, a component of a parallel four-link structure is formed between the guide frame 31 and the head frame 11, ensuring the smooth lifting and lowering of the guide frame 31. When the guide frame 31 is raised, the whole will move upward, so that the guide frame 31 is as far away from its initial position as possible, ensuring a wide field of vision for the driver.

[0041] For the winding device, the gravity-sensing transmission device 10 further includes a driving pulley assembly 312 , a transmission assembly 13 and a belt pressing assembly 14 .

[0042] The driving pulley assembly 312 includes a front driving pulley 121 and a rear driving pulley 122 . The front driving pulley 121 and the rear driving pulley 122 are rotatably mounted on the front end and the rear end of the head frame 11 , respectively.

[0043] Combine Figure 4 The conveying component 13 includes a first conveyor belt component 131, which is installed between the front drive pulley 121 and the rear drive pulley 122. The first conveyor belt component 131 includes a first conveyor belt and a first gravity trigger mechanism 134. The upper part of the first conveyor belt is the first conveying part. The first gravity trigger mechanism 134 is installed below the first conveying part. The first gravity trigger mechanism 134 is triggered by the gravity of the object at the upper end of the first conveying part.

[0044] The belt pressing assembly 14 includes a front belt pressing mechanism 141 and a rear belt pressing mechanism 142. The front belt pressing mechanism 141 is movably mounted at the front end of the head frame 11; the rear drive pulley 122 is movably mounted at the rear end of the head frame 11. The belt pressing assembly 14 has a first working state and a second working state. When the belt pressing assembly 14 is in the first working state, the front belt pressing mechanism 141 is separated from the front drive pulley 121, and the rear belt pressing mechanism 142 cooperates with the rear drive pulley 122 to press the water belt located at the rear end of the head frame 11; when the belt pressing assembly 14 is in the second working state, the rear belt pressing mechanism 142 is separated from the rear drive pulley 122, and the front belt pressing mechanism 141 cooperates with the front drive pulley 121 to press the water belt located at the rear end of the head frame 11; the belt pressing assembly 14 is configured to switch from the first working state to the second working state when the first gravity trigger mechanism 134 is triggered.

[0045] Combine Figures 6 to 12As shown, the first gravity trigger mechanism 134 includes a first sensor 1341, a first trigger member 1342 and a reset member 1343. One end of the first trigger member 1342 is rotatably installed in the head frame 11, and the other end of the first trigger member 1342 is in contact with at least part of the first conveying part. The first sensor 1341 is installed at a predetermined position below the first conveying part. When the first trigger member 1342 moves with the first conveying part to the preset trigger position of the first sensor 1341, the first gravity trigger mechanism 134 is triggered; the reset member 1343 is used to drive the free end away from the first sensor 1341.

[0046] The first trigger member 1342 includes a rotating link 1345, at least one contact roller 1346 and a baffle 1347. One end of the rotating link 1345 is rotatably installed in the head frame 11, and the contact roller 1346 is rotatably installed at the other end of the rotating link 1345. The upper surface of the contact roller 1346 abuts against the first conveying part. The baffle 1347 is installed at one end of the rotating link 1345 close to the contact roller 1346. The first sensor 1341 is a photoelectric sensor, which is installed at a predetermined position on the lower side of the baffle 1347.

[0047] When the water hose joint moves to the upper end of the contact roller 1346, the contact roller 1346 is pressed down, the rotating connecting rod 1345 rotates, and the baffle 1347 approaches the position of the photoelectric sensor. When the baffle 1347 reaches the trigger preset position of the photoelectric sensor, the photoelectric sensor is triggered, and the belt pressing assembly 14 realizes the switching of the working state.

[0048] The reset member 1343 is a spring latch installed at the lower end of the baffle 1347. The lower end of the spring latch is fixed to the head frame 11, and the upper end of the spring latch is used to elastically drive the baffle 1347 to reset.

[0049] The front pressure belt mechanism 141 includes at least one front pressure belt pulley group 1411, each front pressure belt pulley group 1411 includes a flip driving component 1412, a front pressure roller frame 1413 and two front pressure belt pulleys 1414, the two front pressure belt pulleys 1414 are rotatably installed on the front pressure roller frame 1413, and the two front pressure belt pulleys 1414 are arranged side by side on the front pressure roller frame 1413. The flip driving component 1412 is installed on either side of the machine head frame 11 to drive the front pressure roller frame 1413 to flip to approach or move away from the front drive belt pulley 121.

[0050] The front pressure roller frame 1413 includes a flip link 1415, a rotating plate 1416 and two front mounting end plates 1417. The flip link 1415 is driven and connected to the flip driving member 1412. The middle part of the rotating plate 1416 is hinged to the flip link 1415. The two front mounting end plates 1417 are rotatably mounted on the two ends of the rotating plate 1416 and are arranged opposite to each other. The structure of the front mounting end plate 1417 is symmetrical on both sides and a front pressure pulley 1414 is installed on each side. The rotation axis of the front mounting end plate 1417 is located on its central axis surface, and the axis of the front pressure pulley 1414 is located on the plane where the flip link 1415 rotates.

[0051] The above structure ensures that when the front pressure pulley 1414 cooperates with the front drive pulley 121, the front drive pulley 121 is distributed on both sides of the front drive pulley 121, pressing the water hose in contact with the front drive pulley 121 into an arc, thereby increasing the friction between the front drive pulley 121 and the water hose, ensuring that the water hose can be transported backward more stably.

[0052] There are two front pressure pulley groups 1411 , which are symmetrically arranged on both sides of the machine head frame 11 , and the flip driving components 1412 of the two front pressure pulley groups 1411 drive the corresponding front pressure roller frames 1413 to flip synchronously.

[0053] There are two front pressure pulley groups 1411 and the two front pressure pulley groups 1411 are symmetrically arranged on both sides of the head frame 11, which fully ensures that the front pressure mechanism 141 can be tightly pressed with the front drive pulley 121, ensuring that when the front drive pulley 121 rotates, it can drive the water hose and water hose joint thereon to move.

[0054] It can be understood that in some embodiments of the present application, the structures of the front belt pressing mechanism 141 and the rear belt pressing mechanism 142 are the same. In other embodiments of the present application, the structures of the front belt pressing mechanism 141 and the rear belt pressing mechanism 142 adopt different designs. In this embodiment, the rear belt pressing mechanism 142 includes a swinging drive member 1421, two swinging links 1422, two rear mounting end plates 1423 and two rear pressure pulleys 1424. One end of the two swinging links 1422 is symmetrically hinged to the two sides of the head frame 11, and the two rear mounting end plates 1423 are respectively hinged to the other ends of the two swinging links 1422. The structure of the rear mounting end plate 1423 is symmetrical on both sides and a rear pressure pulley 1424 is installed on each side. The rotation axis of the rear mounting end plate 1423 is located on its central axis. The swing drive is installed on the head frame 11 to drive the swinging link 1422 to swing, so that the rear pressure pulley 1424 approaches or moves away from the rear drive pulley 122.

[0055] The swing drive 1421 is generally realized by hydraulic cylinders installed on both sides. By driving the swing link 1422 to swing, the two rear pressure pulleys 1424 are tightly pressed onto the rear drive pulley 122, which can provide a higher friction force than the front drive pulley 121. Since the front drive conveying is only used when the water hose joint passes through, and the rear drive conveying state is generally used, the rear pressure belt mechanism 142 has higher stability and can effectively ensure the transmission stability of the gravity sensing transmission device 10.

[0056] It also includes a bottom tensioning mechanism 315, which includes a bottom support plate 311151, a lateral link 152, a tensioning roller 153 and a tensioning telescopic rod 154. The bottom support plate 311151 is fixedly installed on the lower end of the head frame 11, and the upper end of the lateral link 152 is fixedly installed on the side of the head frame 11. The tensioning telescopic rod 154 has a fixed end and a telescopic end. The fixed end is hinged to the bottom support plate 311151, and the telescopic end is hinged to the lower end of the lateral link 152. The tensioning roller 153 is hinged between the two ends of the lateral link 152. The rotation axis of the tensioning roller 153 is parallel to the rotation axis of the front drive pulley 121. The lower part of the first conveyor belt is in contact with and tensioned on the outer side surface of the tensioning roller 153.

[0057] The transmission component 13 also includes a second transmission belt 136 component 132, which is installed on the rear side of the rear drive pulley 122. The second transmission belt 136 component 132 includes the second transmission belt 136 and a second gravity trigger mechanism 135. The second gravity trigger mechanism 135 is located at the lower end of the second transmission belt 136. The upper part of the second transmission belt 136 is the second transmission part. The second gravity trigger mechanism 135 is installed at the lower end of the second transmission part. The second gravity trigger mechanism 135 includes a second sensor 1351, an elastic support plate 1352 and The second trigger member 1353 and the elastic support plate 1352 are mounted at the lower end of the second conveying portion. The second trigger member 1353 is mounted at the lower end of the elastic support plate 1352. The second sensor 1351 is mounted at a predetermined position below the second conveying portion. When the second trigger member 1353 elastically displaces with the elastic support plate 1352 to the preset trigger position of the second sensor 1351, the second gravity trigger mechanism 135 is triggered. The belt pressing assembly 14 is configured such that when the second gravity trigger mechanism 135 is triggered, the belt pressing assembly 14 switches from the second working state to the first working state. Preferably, the guide device 30 also includes a joint transition assembly 32.

[0058] When the water hose is retracted, the belt pressing assembly 14 first operates in the first working state, which is the rear-driven conveying mode. The water hose is driven to be retracted under the cooperation of the rear belt pressing mechanism 142 and the rear drive pulley 122. When the water hose joint reaches the first conveying part position of the first conveyor belt assembly 131, the water hose joint presses down the water hose because it is heavier than other parts of the water hose. The first gravity trigger mechanism 134 is triggered, and the belt pressing assembly 14 switches to the second working state, which is the front-driven conveying mode. The rear belt pressing mechanism 142 is separated from the rear drive pulley 122, and the front belt pressing mechanism 141 cooperates with the front drive pulley 121 to press the water hose at the front end of the head frame 11 to ensure that the water hose joint can pass smoothly. When the water hose joint continues to move to the position of the second conveyor belt 136, the water hose joint presses the elastic support plate 1352 to move downward, thereby driving the second trigger member 1353 to move downward. When the second trigger member 1353 elastically displaces the second sensor 1351 to the preset trigger position with the elastic support plate 1352, the second gravity trigger mechanism 135 is triggered. At this time, the belt pressing assembly 14 switches from the second working state to the first working state, and continues to change to the rear-drive conveying mode. The gravity sensing transmission device 10 of the present application determines the position of the water hose joint by gravity. The weight of the water hose joint is much greater than the weight of the water hose, ensuring that the state switching of the belt pressing assembly 14 is more accurate and effectively preventing misoperation.

[0059] The guide frame 31 includes two oppositely arranged support plates 311, and a water hose channel 312 is formed between the two support plates 311; the joint transition assembly 32 is installed at the front of the water hose channel 312, and the joint transition assembly 32 includes a guide wheel group 321 and a guide conveyor belt 322. The guide wheel group 321 includes a horizontally arranged triangular roller frame 323 and three guide rollers 324. The triangular roller frame 323 is rotatably installed between the two support plates 311, and the three guide rollers 324 are rotatably installed on the triangular roller frame 323, and the three guide rollers 324 are respectively arranged at the three top angle positions of the triangular roller frame 323; the guide conveyor belt 322 is transmission-installed at the rear end of the guide wheel group 321, and the upper end surface of the guide conveyor belt 322 is its transmission surface, and the transmission surface is arranged parallel to the guide roller 324.

[0060] The guiding device 30 also includes a lateral guiding assembly 33, which includes two guiding side roller groups 331. The two guiding side roller groups 331 are symmetrically installed at the front ends of the two support plates 311. Each guiding side roller group 331 includes an extension arm 332, a support leg 333, a first mounting plate 334, a second mounting plate 335 and at least one lateral roller 336. The extension arm 332 extends to form the front end of the corresponding support plate 311, the support leg 333 is connected to the lower side of the front end of the support plate 311, the first mounting plate 334 is installed on the support leg 333, the second mounting plate 335 is installed at the end of the extension arm 332 and is arranged opposite to the mounting base. The lateral roller 336 is rotatably installed between the first mounting plate 334 and the second mounting plate 335, and the rotation axis of the lateral roller 336 is arranged perpendicular to the rotation axis of the triangular roller frame 323.

[0061] Each guide side roller group 331 has multiple lateral rollers 336, and the distance between the two corresponding lateral rollers 336 decreases from front to back. When the water hose joint is in a position deviating from the guide frame 31, the lateral rollers 336 with a distance decreasing from front to back can effectively guide the water hose joint to the correct position.

[0062] More preferably, the projections of the rotation axes of the plurality of lateral rollers 336 on the first mounting plate 334 or the second mounting plate 335 are located on the same arc.

[0063] In order to enhance the structural stability between the guide frame 31 and the extension arms 332 , a horizontally arranged first reinforcement beam 337 is connected between the ends of the two extension arms 332 , and a horizontally arranged second reinforcement beam 338 is connected between the two legs 333 .

[0064] In an embodiment of the present application, a limiting roller is rotatably installed between the two extension arms 332. The limiting roller is horizontally arranged and a water hose inlet is formed between the limiting roller and the guide wheel group 321. The setting of the limiting roller can effectively ensure that the water hose joint reaches the position of the guide wheel group 321 smoothly.

[0065] In a preferred embodiment of the present application, the upper end surface of the guide conveyor belt 322 includes an uphill section and a horizontal section from front to back, wherein the front end position height of the uphill section is lower than the rear end height, and the water hose joint reaches the front end of the uphill section under the guidance of the guide wheel group 321, and is then transported to the horizontal section and smoothly enters the next storage step.

[0066] In order to ensure the conveying stability of the guide conveyor belt 322, a guide pulley is installed on the portion of the lower end surface of the guide conveyor belt 322 corresponding to the horizontal section.

[0067] In an embodiment of the present application, the triangular roller frame 323 includes two tripods 325 and three support columns 326. The two tripods are rotatably installed on the inner sides of the two support plates 311 respectively. The two tripods are coaxially arranged relative to each other. The three support columns 326 are fixedly connected between the two tripods, and the three support columns 326 are evenly spaced and installed around the rotation axis of the tripod.

[0068] In order to enhance the structural stability of the triangular roller frame 323 , triangular reinforcement plates 327 are installed between the three support columns 326 .

[0069] When the water hose guiding device 30 of this embodiment is in use, the water hose joint abuts against any guide roller 324, driving the triangular roller frame 323 to rotate. At this time, the guide roller 324 revolves around the axis of the triangular roller frame 323. At the same time, the friction between the water hose and the guide roller 324 causes the guide roller 324 to rotate, so that the water hose joint can naturally move from the hanging state at the front end of the guide frame 31 to the guide conveyor belt 322 without getting stuck, which facilitates the storage of the water hose and improves the water hose storage efficiency.

[0070] The lifting drive component 40 is a second hydraulic cylinder, and the base 50 includes a base body and a rotating column fixedly connected to the upper end surface of the base body. The rotating column is located on the rear side of the base body, and the head frame 11 is hinged to the upper end of the rotating column; the two ends of the second hydraulic cylinder are respectively hinged to the base body and the head frame 11, and one end of the second hydraulic cylinder connected to the head frame 11 is higher than the other end.

[0071] The water hose reeling device provided by the present invention, after being installed and used, when the vehicle head needs to be inspected, the rotary lift drive 40 operates to rotate and lift the front end of the gravity sensing transmission device 10. Since the lifting device 20 and the guide device 30 are installed at the front end of the gravity sensing transmission device 10, and the front end part of the gravity sensing device exceeds the base 50, a maintenance space is formed between the gravity sensing transmission device 10 and the base 50, thereby facilitating the inspection of the vehicle head.

[0072] The above are only preferred specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or replacements that can be easily thought of by any technician familiar with this technical field within the technical scope disclosed by the present invention should be covered by the scope of protection of the present invention.
