Description

Technical Field

[0001] The utility model relates to the technical field of fire-fighting equipment, and more specifically, to a hose storage and management device. Background Art

[0002] Fire trucks play a huge role in fire fighting and disaster relief, and there are also many classifications according to their different functions. Among them, a type of hose-laying fire truck is specifically used for laying and recovering hoses at the fire scene to assist firefighters in quickly carrying out fire fighting work or organizing equipment.

[0003] The Chinese patent discloses a hose collection and laying fire truck, including a vehicle main body, which includes a vehicle head, a power compartment and a hose storage compartment. The power compartment is located between the vehicle head and the hose storage compartment, and an opening part at the top of the hose storage compartment forms a hose storage compartment frame; a hose winding and unwinding mechanism and a hose laying mechanism. The characteristics are: the hose laying mechanism is movably arranged on the hose storage compartment frame of the hose storage compartment and is simultaneously slidably matched with the top of the power compartment, and the hose winding and unwinding mechanism is slidably arranged on the hose laying mechanism. Since the hose laying mechanism is arranged on the hose storage compartment frame of the hose storage compartment, the space of the hose storage compartment can be avoided from being occupied, so that the hose storage compartment can store more and longer fire hoses; since the hose winding and unwinding mechanism is slidably arranged on the hose laying mechanism and is above the vehicle head and the hose storage compartment, it will not interfere with the driver's vision and ensure the driving safety of the vehicle. However, the hose laying mechanism of this fire truck extends beyond the vehicle head. When entering some height-limited sections or building-dense areas, the protruding laying mechanism is easy to scratch the building. In the light case, the laying mechanism is bent, and in the heavy case, the vehicle overturns. Therefore, the driving range of the fire truck is greatly limited. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a hose storage and management device. The telescopic arm for guiding the hose of the device is provided with a telescopic structure to avoid the telescopic arm affecting the driving of the fire truck.

[0005] To solve the above technical problems, the technical solution adopted by the utility model is:

[0006] Provide a hose storage and management device, which is installed on the top of the fire truck carriage, including a telescopic arm, a first moving seat, a hose management device and a second moving seat. The first moving seat and the second moving seat are both connected to the top of the fire truck carriage. The telescopic arm is movably connected to the first moving seat. The hose management device is slidably connected to the second moving seat. The first moving seat is arranged beside the second moving seat; the vehicle forward direction is the first direction, and the second direction is on the same horizontal plane as the first direction and perpendicular to each other. The first moving seat is used to drive the telescopic arm to rotate and slide along the second direction, and the second moving seat is used to drive the hose management device to move along the first direction and the second direction.

[0007] With this setting method, when in the working state, the first moving seat works, rotates to make the telescopic arm face the first direction. At the same time, the first moving seat and the second moving seat cooperate with each other to make the telescopic arm and the hose arranging device overlap in the first direction. The telescopic arm extends, and the end crosses the front of the fire truck. The operator passes the hose through the telescopic arm and the hose arranging device in sequence. The telescopic arm works to make the hose move along the telescopic arm towards the hose arranging device. The hose arranging device works to make the hose fall into the carriage below the hose arranging device. While the hose is falling, the second moving seat drives the hose arranging device to move, making it move along a preset route, driving the falling hose to be folded in a Z shape or arranged in zones in the carriage, making the hose storage orderly and tidy, and reducing the sorting difficulty for the staff. When the vehicle is in the driving state, the hose collecting and arranging device is in the standby state. At this time, the telescopic arm shrinks to a state smaller than the vehicle width. The first moving seat drives the telescopic arm to move in the second direction to one side of the vehicle, and then rotates the telescopic arm to make the telescopic arm face the second direction. At this time, the telescopic arm will not exceed the vehicle body range, which is beneficial to reducing the overall volume of the fire truck, avoiding bumps of the collecting and arranging device when the fire truck enters special sections, and improving the applicable range and safety of the fire truck.

[0008] Preferably, the first moving seat includes a first guide rail frame and a first moving component. The first guide rail frame is fixedly installed on the roof of the vehicle and extends along the second direction. The first moving component includes a first sliding mechanism and a rotating mechanism. The first sliding mechanism is slidably connected to the first guide rail frame. The rotating mechanism is installed on the first sliding mechanism, and the telescopic arm is rotatably connected to the first sliding mechanism through the rotating mechanism.

[0009] The roof of the vehicle refers to the top of the fire truck carriage mentioned above. With this setting method, under the cooperation of the first sliding mechanism and the first rotating mechanism, the telescopic arm can slide and rotate along the first guide rail frame.

[0010] Furthermore, the first moving component and the first guide rail frame are connected through a gear-rack transmission pair, and the first moving component drives the gear-rack transmission pair through a motor.

[0011] Preferably, the rotating mechanism includes a chassis, a rotating gear disk, a driving worm and a driving motor. The chassis is installed on the first sliding mechanism, and a circular groove is provided in the middle of the chassis. The rotating gear disk is installed in the circular groove and is rotatably connected to the chassis. The driving worm is arranged beside the rotating gear disk and meshes with the rotating gear disk. The output shaft of the driving motor is connected to the driving worm, and the telescopic arm is fixedly connected to the rotating gear disk.

[0012] With this setting method, when the telescopic arm needs to rotate, the driving motor works, drives the driving worm to rotate, and the rotating gear disk meshing with the driving worm rotates under the drive of the driving worm, thereby driving the telescopic arm to rotate.

[0013] Preferably, the telescopic arm includes a connecting arm, a first support arm, a second support arm and a driving component. The connecting arm is movably connected to the first moving seat. The connecting arm, the first support arm and the second support arm are all hollow. The first support arm is slidably connected to the inner side of the connecting arm, and the second support arm is slidably connected to the inner side of the first support arm. The driving component is used to drive the second support arm and the first support arm to contract or extend. A conveying mechanism is further provided on the upper sides of the first support arm, the second support arm and the connecting arm.

[0014] In the working state of the telescopic arm, the end needs to extend out of the fire truck head to ensure that the guidance of the water hose is not interfered. Therefore, it is necessary to ensure that the maximum extension length of the telescopic arm is not less than a certain value. Through this setting method, the telescopic arm can be telescoped in multiple stages. The second support arm can be retracted into the first support arm, and the first support arm can be retracted into the connecting arm. The length of the connecting arm is the shortest length of the telescopic arm. The structure of hierarchical contraction further reduces the shortest contraction length of the telescopic arm while ensuring the maximum extension length of the telescopic arm, ensuring that the telescopic arm will not exceed the fire truck body in the standby state.

[0015] Furthermore, the driving component includes, but is not limited to, driving methods such as cylinders, hydraulic rods, and gear racks.

[0016] Preferably, the conveying mechanism includes a first belt conveying part and two first pressing roller parts. The first belt conveying part is movably arranged on the upper sides of the connecting arm, the first support arm and the second support arm, and the first pressing roller parts are respectively arranged at both ends of the first belt conveying part.

[0017] Through this setting method, when it is necessary to collect or release the water hose, the belt conveying part provides a supporting effect for the water hose, and the belt conveying part can move along with the water hose, which can not only prevent the water hose from falling, but also will not cause too much hindrance to the movement of the water hose. The first pressing roller parts press and rotate the water hose at both ends of the belt conveying part to provide power for the movement of the water hose.

[0018] Preferably, the first belt conveying part includes a first wheel, a second wheel, a third wheel, a fourth wheel, a fifth wheel, a first tensioning wheel, a second tensioning wheel, a third tensioning wheel and a belt. The inner side of the belt is in contact with the first wheel, the second wheel, the third wheel, the fourth wheel and the fifth wheel, and the outer side of the belt is in contact with the first tensioning wheel, the second tensioning wheel and the third tensioning wheel. The first wheel is rotatably arranged at the end of the upper part of the connecting arm away from the first support arm, the second wheel is rotatably arranged at the end of the second support arm away from the connecting arm, the third wheel is rotatably arranged at the end of the first support arm away from the connecting arm. The fifth wheel and the fourth wheel are respectively rotatably arranged at the bottoms of both ends of the connecting arm. The fifth wheel is arranged away from the first support arm, and the fourth wheel is arranged close to the first support arm. The first tensioning wheel is rotatably arranged on the connecting arm and is located between the first wheel and the fifth wheel. The second tensioning wheel is rotatably arranged on the second support arm and is located between the second wheel and the third wheel. The third tensioning wheel is rotatably arranged on the first support arm and is located between the third wheel and the fourth wheel.

[0019] With this setting method, the belt between the first wheel and the second wheel provides a supporting effect for the water hose. The belt sequentially passes through the first wheel, the second wheel, the first tensioning wheel, the third wheel, the second tensioning wheel, the fourth wheel, the fifth wheel, and the third tensioning wheel and then returns to the first wheel; when the second arm retracts into the first arm, the distance between the belt between the first wheel and the second wheel decreases, the distance between the belt between the second wheel and the first tensioning wheel remains unchanged, the distance between the belt between the first tensioning wheel and the third wheel increases, and the total length of the belt path does not change, avoiding the change of the belt tightness when the second arm expands and contracts; when the first arm is retracted into the connecting arm, the distance between the belt between the first wheel and the second wheel decreases, the distance between the belt between the third wheel and the second tensioning wheel remains unchanged, the distance between the belt between the second tensioning wheel and the fourth wheel becomes larger, and the total length of the belt remains unchanged, which can also avoid the influence of the expansion and contraction of the first arm on the belt tightness; the third tensioning wheel is arranged between the first wheel and the fifth wheel, making the belt in an M-shaped path, ensuring that the belt can be in close contact with both the first wheel and the fifth wheel to prevent the belt from slipping.

[0020] Preferably, the first pressing roller part includes a first mounting seat, a first power roller, a first driving cylinder, a first crank, a first roller frame, and a first belt pressing roller. The first mounting seat is fixedly connected to the second arm or the connecting arm. The first power roller is rotatably connected to the first mounting seat. One side of the first roller frame is rotatably connected to the first mounting seat, and the other side of the first roller frame is rotatably connected to the first belt pressing roller. The first driving cylinder drives the first roller frame to rotate through the first crank, and the first roller frame can drive the first belt pressing roller to rotate close to or away from the first power roller.

[0021] With this setting method, in the standby state, the first belt pressing roller is lifted, and the water hose is laid between the first power roller and the first belt pressing roller; when it is necessary to drive the water hose to move, the first power roller rotates, the first driving cylinder works, and drives the first belt pressing roller to rotate and press down through the crank. The first belt pressing roller presses the water hose against the surface of the first power roller, increasing the friction between the water hose and the first power roller, so that the first power roller drives the water hose to move.

[0022] Preferably, a flushing nozzle for cleaning the water hose is further provided on the first pressing roller part, and the flushing nozzle is fixedly installed on the first roller frame.

[0023] With this setting method, when the first pressing roller part stores the water hose, the flushing nozzle can automatically spray water flow to flush the passing water hose.

[0024] Preferably, the second moving seat includes a second moving component, a second guide rail frame, and a third guide rail frame. The second guide rail frame extends along the second direction, the third guide rail frame extends along the first direction, the second guide rail frame is slidably connected to the third guide rail frame, the second moving component is slidably connected to the second guide rail frame, and the tape arranging device is installed on the second moving component.

[0025] With this arrangement, the second moving component and the second guide rail frame can respectively move the tape arranging device along the second direction and the first direction. The combination of the two can move the tape arranging device to any position within the plane, so as to control the path of the tape arranging device for placing the water hose. The second moving seat cooperates with the tape arranging device to achieve the effect of sorting the stacked water hoses.

[0026] Furthermore, the second moving component is connected and driven to the second guide rail frame, and the second guide rail frame is connected and driven to the third guide rail frame through a gear-rack transmission pair.

[0027] Preferably, the tape arranging device includes two second pressing roller parts, a second tape conveying part, and a housing. The housing is installed on the second moving component, the second tape conveying part is arranged on the top of the housing, the second pressing roller parts are respectively arranged at both ends of the second tape conveying part, and the second pressing roller part is rotatably connected to the housing.

[0028] With this arrangement, the water hose extending from the connecting arm sequentially passes through the second pressing roller part, the second tape conveying part, and the other second pressing roller part and then drops. The second pressing roller parts respectively provide power for the movement of the water hose at both ends of the second tape conveying part, the second tape conveying part provides support for the water hose, and the water hose loses support after being sent out by the second pressing roller part far away from the telescopic arm and vertically falls into the carriage at the bottom. The tape arranging device moves on the second moving seat, so that the falling water hoses are stacked neatly.

[0029] Preferably, the second pressing roller part includes a second mounting seat, a second power roller, a second driving cylinder, a second crank, a second roller frame, and a second pressing belt roller. The second mounting seat is fixedly connected to the second support arm or the connecting arm, the second power roller is rotatably connected to the second mounting seat, one side of the second roller frame is rotatably connected to the second mounting seat, the other side of the second roller frame is rotatably connected to the second pressing belt roller, the second driving cylinder drives the second roller frame to rotate through the crank, and the second roller frame can drive the second roller to rotate close to or away from the second power roller.

[0030] With this arrangement, in the standby state, the second pressing belt roller is lifted, and the water hose is laid between the second power roller and the second pressing belt roller; when it is necessary to drive the water hose to move, the second power roller rotates, the second driving cylinder works, and drives the second pressing belt roller to rotate and press down through the second crank. The second pressing belt roller presses the water hose against the surface of the second power roller, increasing the friction between the water hose and the second power roller, so as to drive the water hose to move by the second power roller.

[0031] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0032] (1) The telescopic arm of the present device for guiding the water hose is provided with a telescopic structure. When working, it extends to provide guidance and support for the water hose.

[0047] Embodiment 1

[0048] As Figures 1 to 4The figure shows a first embodiment of a hose storage device of the present utility model, which is installed on the top of a fire truck compartment. It includes a telescopic arm 1, a first moving seat 2, a hose arranging device 3 and a second moving seat 4. The first moving seat 2 and the second moving seat 4 are both connected to the top of the fire truck compartment. The telescopic arm 1 is movably connected to the first moving seat 2. The hose arranging device 3 is slidably connected to the second moving seat 4. The first moving seat 2 is arranged beside the second moving seat 4. The vehicle forward direction is the first direction, and the second direction is on the same horizontal plane as the first direction and perpendicular to each other. The first moving seat 2 is used to drive the telescopic arm 1 to rotate and slide along the second direction. The second moving seat 4 is used to drive the hose arranging device 3 to move along the first direction and the second direction.

[0049] Through this setting method, when in the working state, the first moving seat 2 works. It rotates to make the telescopic arm 1 face the first direction. At the same time, the first moving seat 2 and the second moving seat 4 cooperate with each other to make the telescopic arm 1 and the hose arranging device 3 overlap in the first direction. The telescopic arm 1 extends, and its end crosses the front of the fire truck. The operator passes the hose through the telescopic arm 1 and the hose arranging device 3 in sequence. The telescopic arm 1 works to make the hose move along the telescopic arm 1 towards the hose arranging device 3. The hose arranging device 3 works to make the hose fall into the compartment below the hose arranging device 3. While the hose is falling, the second moving seat 4 drives the hose arranging device 3 to move, making it move along a preset route, driving the falling hose to be folded in a Z shape or arranged in zones in the compartment, making the hose storage orderly and tidy, and reducing the sorting difficulty for the staff. When the vehicle is in the driving state, the hose storage device is in the standby state. At this time, the telescopic arm 1 is shortened to a state smaller than the vehicle width. The first moving seat 2 drives the telescopic arm 1 to move in the second direction to one side of the vehicle, and then rotates the telescopic arm 1 to make the telescopic arm 1 face the second direction. At this time, the telescopic arm 1 will not exceed the vehicle body range, which is beneficial to reducing the overall volume of the fire truck, avoiding bumps of the storage device when the fire truck enters special sections, and improving the applicable range and safety of the fire truck.

[0050] As an embodiment of the present utility model, the first moving seat 2 includes a first guide rail frame 21 and a first moving component 22. The first guide rail frame 21 is fixedly installed on the fire truck. The first moving component 22 includes a first sliding mechanism 23 and a rotating mechanism 24.

The rotating mechanism 24 is installed on the first sliding mechanism 23, and the telescopic arm 1 is rotationally connected to the first sliding mechanism 23 through the rotating mechanism 24.

[0051] Through this setting method, with the cooperation of the first sliding mechanism 23 and the first rotating mechanism 24, the telescopic arm 1 can slide and rotate along the first guide rail frame 21.

[0052] As an embodiment of the present utility model, the first moving assembly 22 is connected to the first guide rail frame 21 through a gear-rack transmission pair, and the first moving assembly 22 drives the gear-rack transmission pair through a motor.

The output shaft of the driving motor 244 is connected to the driving worm 243, and the telescopic arm 1 is fixedly connected to the rotating gear disk 242.

[0054] In this setting mode, when the telescopic arm 1 needs to rotate, the driving motor 244 works to drive the driving worm 243 to rotate. The rotating gear disk 242 meshing with the driving worm 243 rotates under the drive of the driving worm 243, thereby driving the telescopic arm 1 to rotate.

[0055] As an embodiment of the present utility model, the telescopic arm 1 includes a connecting arm 11, a first support arm 12, a second support arm 13, and a driving assembly 14.

The first support arm 12 is slidably connected to the inner side of the connecting arm 11, and the second support arm 13 is slidably connected to the inner side of the first support arm 12. The driving assembly 14 is used to drive the second support arm 13 and the first support arm 12 to contract or extend. A conveying mechanism 15 is further provided on the upper sides of the first support arm 12, the second support arm 13, and the connecting arm 11.

[0056] In the working state of the telescopic arm 1, the end needs to extend out of the fire truck head to ensure that the guidance of the water hose is not interfered. Therefore, it is necessary to ensure that the maximum extension length of the telescopic arm 1 is not less than a certain value. In this setting mode, the telescopic arm 1 can be telescopically extended in multiple stages. The second support arm 13 can be retracted into the first support arm 12, the first support arm 12 can be retracted into the connecting arm 11, and the length of the connecting arm 11 is the shortest length of the telescopic arm 1. The hierarchical contraction structure further reduces the shortest contraction length of the telescopic arm 1 while ensuring the maximum extension length of the telescopic arm 1, ensuring that the telescopic arm 1 will not exceed the fire truck body in the standby state.

[0060] Through this setting method, when it is necessary to collect or release the water belt, the first belt conveying part 16 provides a supporting effect for the water belt, and the first belt conveying part 16 can move along with the water belt, which can not only prevent the water belt from falling, but also will not cause too much hindrance to the movement of the water belt. The first pressing roller parts 17 then press and rotate the water belt at both ends of the first belt conveying part 16 to provide power for the movement of the water belt.

[0061] As an embodiment of the present utility model, the first belt conveying part 16 includes a first wheel 161, a second wheel 162, a third wheel 163, a fourth wheel 164, a fifth wheel 165, a first tensioning wheel 166, a second tensioning wheel 167, a third tensioning wheel 168 and a belt 169.
