As a crucial component of fire trucks and other rescue vehicles, the rapid and convenient retrieval and deployment of hoses is essential for timely fire suppression and rescue operations.

[0004] In summary, existing fire trucks have technical problems such as high hose storage location, inconvenient hose retrieval, and reduced rescue efficiency. Utility Model Content

[0035] The purpose of this application is to overcome the above-mentioned technical deficiencies and propose a vehicle-mounted water hose retrieval and placement device to solve the technical problems of water hoses being stored at a high position, inconvenient retrieval and placement, and affecting rescue efficiency in the prior art.

[0036] To achieve the above-mentioned technical objectives, this application adopts the following technical solution:

[0037] This application provides a vehicle-mounted water hose loading and unloading device, such as... Figures 1-4 As shown, Figure 1 This is a schematic diagram of the storage state of a vehicle-mounted water hose retrieval and placement device provided in an embodiment of this application;

[0038] Figure 2 This is a side view of a vehicle-mounted water hose loading and unloading device provided in an embodiment of this application;

[0040] Figure 4 This is a structural schematic diagram of the working state of a vehicle-mounted water hose loading and unloading device provided in an embodiment of this application.

[0041] A vehicle-mounted water hose loading and unloading device includes a base 1, a support frame 2, a linkage mechanism, a hydraulic cylinder 3, a winch mechanism, a hydraulic motor 4, and a transmission mechanism.

[0042] Base 1;

[0043] Support frame 2, the support frame 2 having a receiving space;

[0044] A linkage mechanism, wherein both ends of the linkage mechanism are rotatably connected to the base 1 and the support frame 2, respectively;

[0045] Hydraulic cylinder 3, the two ends of which are respectively connected to the linkage mechanism and the support frame 2 for transmission;

[0046] A winch mechanism, wherein the winch mechanism is located in the receiving space;

[0047] Hydraulic motor 4, which is connected to the support frame 2;

[0048] The transmission mechanism is connected at both ends to the hydraulic motor 4 and the winch mechanism, respectively.

[0049] This application utilizes a linkage mechanism to rotatably connect to the base 1 and support frame 2. The base 1 is fixed in position, and the hydraulic cylinder 3 drives the linkage mechanism to rotate. During rotation, the support frame 2 remains horizontal, and its height can be adjusted between a high and a low position. The high position facilitates storage of the support frame 2, while the low position allows operators to easily retrieve the hose from the winch mechanism. Simultaneously, the transmission mechanism is connected to the hydraulic motor 4 and the winch mechanism. When the hose needs to be retrieved, the hydraulic motor 4 drives the transmission mechanism to rotate, which in turn drives the winch mechanism to rotate, allowing the hose wound on the winch mechanism to rotate out. After use, the hydraulic motor 4 drives the transmission mechanism to rotate in the opposite direction, which in turn drives the winch mechanism to rotate in reverse, causing the released hose to retract. This device lowers the hose height, allowing operators to operate directly on the ground, achieving automatic hose reeling and deployment, and improving rescue efficiency.

[0050] Base 1 is the foundation of the vehicle-mounted water hose loading and unloading device. It is fixed to the vehicle and provides stable support for the entire device.

[0051] The support frame 2 has a receiving space for placing the winch mechanism, and the support frame 2 can be rotatably connected to the base 1 through a linkage mechanism.

[0052] The two ends of the linkage mechanism are rotatably connected to the base 1 and the support frame 2, respectively. The two ends of the hydraulic cylinder 3 are drively connected to the linkage mechanism and the support frame 2, respectively, so that the support frame 2 can maintain a horizontal state and adjust its height under the drive of the hydraulic cylinder 3.

[0053] The extension and retraction of the hydraulic cylinder 3 can drive the linkage mechanism to rotate, thereby realizing the height and horizontal position adjustment of the support frame 2. The higher position is farther away for storage, while the lower position is closer for easy access to the water hose.

[0054] The winch mechanism is located in the housing space of the support frame 2. The hydraulic motor 4 is connected to the support frame 2 and is connected to the winch mechanism through a transmission mechanism.

[0055] Driven by the hydraulic motor 4, the transmission mechanism rotates, which in turn drives the winch mechanism to rotate, thus enabling the automatic loading and unloading of the water hose.

[0056] The height and horizontal position of the support frame 2 can be adjusted through the cooperation of hydraulic cylinder 3 and linkage mechanism, facilitating the storage and retrieval of water hoses at different horizontal heights. In the low position, operators can operate directly on the ground without climbing, improving operational safety. The cooperation of hydraulic motor 4 and winch mechanism enables automatic deployment and retraction of the water hose, greatly reducing manual labor intensity. The automated deployment and retraction process significantly improves rescue efficiency and reduces rescue delays caused by operational inconvenience. The device has a compact design, effectively utilizing vehicle space for easy storage and transportation.

[0057] In some embodiments of this application, the linkage mechanism includes a first link 5 and a second link 6, the first link 5 and the second link 6 are parallel to each other, the first ends of the first link 5 and the second link 6 are rotatably connected to the base 1, and the second ends of the first link 5 and the second link 6 are rotatably connected to the support frame 2.

[0058] The linkage mechanism consists of a first link 5 and a second link 6. These two links are parallel to each other and form a stable linkage mechanism.

[0059] The first ends of both the first link 5 and the second link 6 are rotatably connected to the base 1, while their second ends are rotatably connected to the support frame 2. This design allows the support frame 2 to rotate at a fixed point on the base 1.

[0060] The force of the hydraulic cylinder 3 is transmitted to the support frame 2 through the linkage mechanism, enabling the support frame 2 to be height-adjusted while maintaining a horizontal position. When the hydraulic cylinder 3 extends or retracts, the linkage mechanism rotates around the connection point of the base 1, thereby causing the support frame 2 to rise or fall.

[0061] By controlling the extension and retraction of the hydraulic cylinder 3, the support frame 2 can be easily adjusted to a high or low position. In the high position, the winch mechanism on the support frame 2 is far from the ground, making it easy to store; in the low position, the winch mechanism is close to the ground, making it easy for operators to retrieve and deploy water hoses.

[0062] The parallel linkage design increases the stability of the entire mechanism, making the support frame 2 more stable during height adjustment. Because the two linkages are parallel, the force of the hydraulic cylinder 3 can be evenly distributed on the support frame 2, reducing the pressure from single-point stress and extending the service life of the device. The stable structural design reduces potential swaying or instability during height adjustment, improving operational safety.

[0063] In some embodiments of this application, a plurality of first hinge shafts 7 are also included, each of which passes through the side of the base 1. The base 1 is rotatably connected to the hydraulic cylinder 3, the first connecting rod 5, and the second connecting rod 6 respectively through the first hinge shafts 7.

[0064] In some embodiments of this application, a plurality of second hinge shafts 8 are also included, all of which pass through the side of the support frame 2. The support frame 2 is rotatably connected to the first connecting rod 5 and the second connecting rod 6 respectively through the second hinge shafts 8.

[0065] The first hinge shaft 7 passes through the side of the base 1, while the second hinge shaft 8 passes through the side of the support frame 2. These hinge shafts enable rotatable connections between the base 1 and the hydraulic cylinder 3, the first connecting rod 5, and the second connecting rod 6, as well as between the support frame 2 and the first connecting rod 5 and the second connecting rod 6.

[0066] Each first hinge shaft 7 is connected to one end of the hydraulic cylinder 3, the first connecting rod 5, and the second connecting rod 6, respectively, while each second hinge shaft 8 is connected to the other end of the first connecting rod 5 and the second connecting rod 6, respectively. This design allows the connecting rods to rotate freely on the hinge shafts, thereby realizing the lifting and positioning of the support frame 2.

[0067] In some embodiments of this application, a third hinge shaft is also included, which passes through the middle of the first connecting rod 5. The hydraulic cylinder 3 is rotatably connected to the first connecting rod 5 via the third hinge shaft and is located on the side of the first connecting rod 5 away from the second connecting rod 6.

[0068] When the hydraulic cylinder 3 extends or retracts, it transmits force through the first hinge shaft 7, causing the first connecting rod 5 and the second connecting rod 6 to rotate around the hinge shaft, thereby pushing or pulling the support frame 2 to achieve height adjustment of the support frame 2.

[0069] The third hinge shaft passes through the middle of the first link 5, providing an additional rotatable connection point. This hinge shaft allows the hydraulic cylinder 3 to be rotatably connected to the first link 5 and is located on the side of the first link 5 away from the second link 6.

[0070] When the hydraulic cylinder 3 extends or retracts, it pushes or pulls the first connecting rod 5 through the third hinge shaft, making the lifting and lowering of the support frame 2 more efficient.

[0071] The first link 5 rotates at the third hinge axis. Since the first link 5 is parallel to the second link 6 and is connected to the base 1 and the support frame 2 through the first hinge axis 7 and the second hinge axis 8, the movement of the first link 5 will drive the second link 6 to move synchronously, thereby realizing the synchronous lifting and lowering of the support frame 2.

[0072] Since the hydraulic cylinder 3 is directly connected to the first connecting rod 5, the lifting speed and position of the support frame 2 can be controlled more precisely.

[0073] In some embodiments of this application, the winch mechanism includes a first disc body 9 and a second disc body 10, the first disc body 9 and the second disc body 10 are disposed opposite to each other, and both the first disc body 9 and the second disc body 10 are rotatably connected to the support frame 2.

[0074] The winch mechanism consists of a first disc 9 and a second disc 10, which are arranged opposite each other and connected to the support frame 2 via a rotatable connection. It can rotate freely on the support frame 2, thereby enabling the winding and unwinding of the water hose.

[0075] In some embodiments of this application, the winch mechanism further includes a bearing seat 11, which is sleeved around the rotating shaft of the first disc body 9. The bearing seat 11 is rotatably connected to the first disc body 9 and fixedly connected to the support frame 2.

[0076] The bearing housing 11 is designed to be fitted around the shaft of the first disc 9, providing support for the shaft so that the first disc 9 can rotate.

[0077] The bearing housing 11 and the first disc 9 are rotatably connected, which means that the first disc 9 can rotate freely within the bearing housing 11 without generating excessive friction or resistance.

[0078] The bearing housing 11 is fixedly connected to the support frame 2, which provides a stable fulcrum for the winch mechanism and ensures the stability of the winch during operation.

[0079] The bearings within the bearing housing 11 significantly reduce friction during rotation, improving winch efficiency and reducing energy loss. The fixedly connected bearing housing 11 provides robust support for the winch, reducing vibration during operation and enhancing operational stability.

[0080] In some embodiments of this application, the transmission mechanism includes a first gear 12 and a second gear 13. The first gear 12 is connected to the output shaft of the hydraulic motor 4, the second gear 13 is meshed with the first gear 12, and the second gear 13 is connected to the rotating shaft of the second disc 10.

[0081] The transmission mechanism consists of a first gear 12 and a second gear 13. These two gears mesh with each other to transmit power and motion.

[0082] The first gear 12 is connected to the output shaft of the hydraulic motor 4. When the hydraulic motor 4 is working, its output shaft rotates, thereby driving the first gear 12 to rotate.

[0083] When the first gear 12 rotates, it drives the second gear 13 to rotate through the meshing action between the gears. This meshing connection ensures the efficiency and accuracy of power transmission.

[0084] The second gear 13 is connected to the shaft of the second disc 10, which means that the rotation of the second gear 13 will be directly transmitted to the second disc 10, thereby realizing the winding or unwinding action of the second disc 10.

[0085] When the winch is in operation, the operator can rotate the winch mechanism through the drive system. The bearings in the bearing housing 11 allow this rotation to proceed smoothly, while the water hose is wound between or released from the first disc body 9 and the second disc body 10.

[0086] Gear drive is a highly efficient transmission method that can transmit the power of the hydraulic motor 4 to the second disc 10 with almost no loss. Gear meshing provides a precise transmission ratio, allowing the operator to accurately control the winding speed and torque of the winch.

[0087] In some embodiments of this application, a connector 14 is also included, which is located between the first disc body 9 and the second disc body 10.

[0088] The connector 14 is used to connect the two ends of a water hose or to other water pipes or equipment. It typically has a specific shape and size to match the hose's interface.

[0089] The connector 14 is typically designed with a sealing ring or sealing surface to ensure an effective seal after connection, preventing leakage of the hose under high-pressure water flow.

[0090] The connector 14 may be connected to the hose by threaded connection, quick coupling, flange connection or other mechanical fastening methods.

[0091] When installing a water hose, connect one end of the connector 14 to one end of the water hose, and then connect the other end to the water pipe or equipment. Secure the connector by rotating, pressing or other means to complete the installation.

[0092] In some embodiments of this application, a bracket 15 is also included, which is fixedly connected to the support frame 2, and the hydraulic motor 4 is fixedly connected to the bracket 15.

[0093] The bracket 15 is an additional structural component that is fixedly connected to the support frame 2, providing a stable mounting base for the hydraulic motor 4.

[0094] The hydraulic motor 4 is fixedly connected to the bracket 15. This is to ensure that the hydraulic motor 4 remains stable during operation and will not shift due to external forces or vibrations.

[0095] The vehicle-mounted hose retrieving and deploying device includes a base 1 fixed to the vehicle; a pair of parallel first connecting rods 5 and second connecting rods 6, one end of which is connected to the base 1 via a first hinge shaft 7, and the other end is connected to the support frame 2 via a second hinge shaft 8; the two ends of a hydraulic cylinder 3 are respectively connected to the base 1 via the first hinge shaft 7 and to the first connecting rod 5 via a third hinge shaft; a first disc 9 is mounted on the support frame 2 via a bearing seat 11; a hydraulic motor 4 is mounted on a bracket 15; the bracket 15 is mounted on the support frame 2; a first gear 12 is mounted on the hydraulic motor 4; a second gear 13 is mounted on the second disc 10; and a connector 14 is fixed between the first disc 9 and the second disc 10 for hose installation. When the hydraulic motor 4 rotates, it drives the second gear 13 to rotate via the first gear 12, thereby retrieving and deploying the hose; when the hydraulic cylinder 3 extends, it drives the first connecting rod 5 and the second connecting rod 6 to rotate around the hinge shaft, thereby moving the winch mechanism on the support frame 2 forward and downward, reducing the height of the winch mechanism for easier operation.

[0096] The vehicle-mounted hose loading and unloading device is fixed to the vehicle base 1 and connected to the support frame 2 via a pair of parallel first connecting rods 5 and second connecting rods 6, forming a double-link mechanism. A hydraulic cylinder 3 is connected between the base 1 and the first connecting rods 5 to drive the linkage mechanism.

[0097] The first disc 9 is mounted on the support frame 2 via the bearing seat 11, and the hydraulic motor 4 is mounted on the bracket 15, which is fixed to the support frame 2. The first gear 12 is mounted on the hydraulic motor 4, and the second gear 13 is mounted on the second disc 10.

[0098] When the hydraulic motor 4 rotates, the first gear 12 drives the second gear 13 to rotate, thereby realizing the winding and unwinding of the water hose.

[0099] When the hydraulic cylinder 3 extends, it pushes the first connecting rod 5 and the second connecting rod 6 to rotate around the hinge axis, causing the winch mechanism on the support frame 2 to move forward and downward, thereby reducing the height of the winch mechanism and facilitating operation.

[0100] Compared with the prior art, the beneficial technical effects of the technical solution provided in this application include:

[0101] This application utilizes a linkage mechanism to rotatably connect to the base 1 and support frame 2. The base 1 is fixed in position, and the hydraulic cylinder 3 drives the linkage mechanism to rotate. During rotation, the support frame 2 remains horizontal, and its height can be adjusted between a high and a low position. The high position facilitates storage of the support frame 2, while the low position allows operators to easily retrieve the hose from the winch mechanism. Simultaneously, the transmission mechanism is connected to the hydraulic motor 4 and the winch mechanism. When the hose needs to be retrieved, the hydraulic motor 4 drives the transmission mechanism to rotate, which in turn drives the winch mechanism to rotate, allowing the hose wound on the winch mechanism to rotate out. After use, the hydraulic motor 4 drives the transmission mechanism to rotate in the opposite direction, which in turn drives the winch mechanism to rotate in reverse, causing the released hose to retract. This device lowers the hose height, allowing operators to operate directly on the ground, achieving automatic hose reeling and deployment, and improving rescue efficiency.

[0102] Those skilled in the art will understand that the steps, measures, and schemes in the various operations, methods, processes, and procedures discussed in this application can be alternated, modified, rearranged, decomposed, combined, or deleted.

[0103] The specific embodiments described above do not constitute a limitation on the scope of protection of this application. Any other corresponding changes and modifications made based on the technical concept of this application should be included within the scope of protection of the claims of this application.
