Description

Technical Field

[0001] The present invention relates to the technical field of electric winches, in particular to an electric winch device. Background Art

[0002] With the continuous development of marine transportation and offshore operations, electric winches, as a key piece of equipment, have become widely used in vessels, offshore platforms, oil drilling platforms, and other fields. Electric winches play a crucial role in operations such as reeling in and out, adjusting ropes and cables, and performing other operations. They are used not only in navigation, fishing, and rescue missions, but also in a wide range of fields, including offshore oil and gas production and offshore wind power construction, carrying out critical operational tasks. However, traditional electric winches still face technical challenges in their long-term use, directly impacting their performance, stability, and efficiency.

[0003] The impact of ambient temperature fluctuations on equipment performance is gaining increasing attention, particularly in high and low temperature environments. Traditional electric winches often face operational challenges. In high-temperature environments, friction and heat accumulation can easily lead to overheating within the equipment. Lubricant oxidation and viscosity changes can reduce equipment efficiency and even cause seizures or failures.

The outer wall of the stabilizing wheel is slidably connected to a disk loader, and the disk loader is threadedly connected to the outer wall of the screw rod.

[0008] Preferably, a turbofan is installed on one end of the outer wall of the screw rod, and the screw rod passes through the blower box and is fixedly connected to one end of the second pulley.

[0010] Preferably, a gear ring is provided at one end of the outer wall of the rope winder, and the gear ring is meshingly connected to the transmission gear.

[0011] Preferably, the lighting and heating mechanism includes a lighting lamp and a heating lamp, the lighting lamp is installed on the top of the protective shell, and the heating lamp is installed inside the protective shell, and they are electrically connected in parallel with the energy storage group.

[0012] Preferably, the protective shell is divided into an upper part and a lower part, a running groove is provided on the side where the upper part and the lower part touch each other, and the plurality of filters are connected to the running groove.

[0013] Preferably, the outer walls of the pulley 2 and the pulley 1 are provided with belts, and the outer walls of the two synchronous wheels are provided with synchronous belts for transmitting power.

[0014] Preferably, one end of the rope winder is rotatably connected to the inner wall of the protective shell, and the other end is rotatably connected to the top of the frame.

[0015] Working principle: When the electric winch device is installed on a marine vessel, when the winch is used, first turn on the motor to drive the rope winch connected to the reducer to rotate forward or reverse, and through the power transmission of the power component, the upper winding device set on the front of the device is driven by the rotating thread of the screw rod to achieve left and right displacement, thereby achieving the whole line effect.

[0016] However, the state of the winch changes with different usage scenarios. For example, when the ship is on a temperate latitude route, the friction of the internal parts of the reducer due to thermal expansion and contraction increases, which will cause the temperature to remain high. As a result, the high temperature of the reducer will accelerate the oxidation of the oil, causing viscosity changes that affect the overall service life. However, during the operation of the entire line assembly, this device will synchronously drive the turbofan to rotate inside the blower box, thereby generating wind and discharging it into the protective shell through the air outlet of the blower box. After internal air circulation, the air is discharged from the filter on the other side, thereby improving internal heat dissipation.

[0017] Aside from tropical routes, when a vessel is in cold latitudes, the operating state of the device changes as the temperature drops. The low temperature inside the reducer increases the viscosity of the lubricating oil, thus affecting the overall operation of the device. However, the winch device of the present invention has a separate heating lamp installed inside the protective shell during use. The heating lamp is controlled by the energy storage group switch and combines with the airflow generated above to evenly heat the internal equipment. The circulation of hot and cold air prevents the temperature inside the protective shell from rising too high, thereby maintaining a good operating temperature.

[0018] The energy storage group stores electricity through the daily rotation of the rope winch. Specifically, during the daily forward and reverse rotation of the rope winch, the rotor connected to the transmission gear will be driven to rotate around the armature in the connector through the gear ring and the gear ratio engagement, thereby generating an electromotive force. After the induced current is generated, it is input to the input end of the energy storage group through the power cord. During daily use, it can also supply power to the lighting lamp, making it convenient for the entire device to be used in different visual conditions.

[0019] The present invention provides an electric winch device having the following beneficial effects:

[0020] 1. By combining the design of the turbofan and blower box in the cable management assembly, the present invention can effectively remove the heat generated during the operation of the equipment and discharge it through air circulation. Especially in high-temperature environments, the airflow system of the device effectively reduces the temperature inside the equipment through the cooperation of the filter and the blower box, avoiding equipment failure or damage due to overheating, and improving the stability and service life of the equipment.

[0021] 2. By combining the armature and rotor with permanent magnets, the present invention converts the mechanical energy of the rope winder into electrical energy and stores it in an energy storage system. This energy recovery function effectively eliminates the problem of energy waste during device operation, enabling the device to support functions such as lighting and heating through stored energy without the need for external power supply, thereby improving the device's autonomous operation and energy utilization efficiency.

[0022] 3. The cable management assembly design utilizes a screw and stabilizing wheel to ensure smooth movement of the loading device, avoiding malfunctions caused by vibration or unstable movement. Furthermore, the screw design combined with the turbofan increases the device's heat dissipation capacity, preventing performance degradation due to overheating. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The following will clearly and completely describe the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Please see the attached Figure 1 -Attached Figure 3The embodiment of the present invention provides an electric winch device, including a frame 1 and a protective shell 3. A motor 2 is provided on the top of the frame 1. The output end of the motor 2 is connected to the input end of a reducer 15 fixedly connected to the inside of the protective shell 3. The protective shell 3 is fixedly connected to the top of the frame 1. The output end of the reducer 15 is fixedly connected to a rope winch 17 for driving the rope winch 17 to rotate forward or reverse. A wire management component is installed at one end of the frame 1. A blower box 6 is installed at one end of the wire management component. The blower box 6 is fixedly connected to one end of the protective shell 3. The blower box 6 provides power to the wire management component through a transmission component. The front side of the protective shell 3 A filter 12 is provided, one end of the protective shell 3 is fixedly connected to the blower box 6, and a turbofan 13 is installed at one end of the wire management assembly, which is used to rotate with the wire management assembly and transport airflow to the inside of the protective shell 3 under the external surround of the blower box 6. One of the filters 12 is installed at one end of the blower box 6, and a gear ring is provided at one end of the outer wall of the rope winch 17. The gear ring is meshed with the transmission gear 20. The protective shell 3 is divided into an upper part and a lower part, and an operating groove is provided on the side where the upper part and the lower part touch each other. Multiple filters 12 are communicated with the operating grooves, and one end of the rope winch 17 is rotatably connected to the inner wall of the protective shell 3, and the other end is rotatably connected to the top of the frame 1.

[0032] Specifically, motor 2 is mounted on top of frame 1, with its output connected to the input of reducer 15. Reducer 15 converts the power provided by motor 2 into torque suitable for driving winch 17, which then rotates forward or backward to retract and extend the rope. The design of reducer 15 ensures smooth power transmission between motor 2 and winch 17, ensuring efficient operation of the equipment.

[0033] To ensure smooth operation of the rope winder 17, a cable management assembly is mounted on one end of the frame 1. One end of the cable management assembly is connected to the bellows 6, which in turn provides power to the cable management assembly via a transmission assembly. This power transmission helps the cable management assembly 17 maintain an orderly arrangement of the ropes, preventing them from becoming tangled during use.

[0034] Blower box 6 not only provides power but also dissipates heat. The combination of turbofan 13 and blower box 6 ensures a continuous airflow. Air flows through the interior of protective housing 3, removing heat generated by the device during operation and ultimately discharging it through another filter 12. This airflow circulation design effectively reduces the device's temperature even in high-temperature environments, preventing overheating and ensuring long-term, efficient operation.

[0035] At the same time, multiple filters 12 are installed on the front side of the protective shell 3 to ensure air circulation while preventing dust and impurities from entering the protective shell 3, maintaining clean airflow and preventing the device from affecting its heat dissipation. The filters 12 communicate with the operating grooves in the protective shell 3, allowing airflow to flow smoothly and reducing heat dissipation problems caused by poor airflow.

[0036] A toothed ring is mounted on one end of the outer wall of the rope winch 17, which meshes with the transmission gear 20 to ensure stable power transmission. The cooperation between the toothed ring and the gear reduces energy loss during operation, while ensuring that the rope winch 17 can work efficiently during rotation, and noise and vibration during transmission are also controlled.

[0037] To enhance the stability and durability of the equipment, both ends of the rope winder 17 are rotatably connected. One end is rotatably connected to the inner wall of the protective shell 3, and the other end is connected to the top of the frame 1. This allows the rope winder 17 to rotate smoothly during operation, unaffected by external friction and vibration, improving work efficiency and extending the service life of the equipment.

[0038] Please see the attached Figure 3 -Attached Figure 4 The transmission assembly includes multiple synchronous wheels 5, one of which is fixedly connected to one end of the rope twister 17, one of which is rotatably connected to one side of the protective shell 3, one end of the synchronous wheel 5 is rotatably connected to a pulley 1 7, one end of the protective shell 3 is fixedly connected to a protective box 4, the inner wall of the protective box 4 is rotatably connected to a pulley 2 8, the outer walls of the pulley 2 8 and the pulley 1 7 are provided with belts, and the outer walls of the two synchronous wheels 5 are provided with synchronous belts for transmitting power.

[0039] Specifically, the transmission assembly design of the present invention utilizes multiple synchronous pulleys 5 and a belt system to transmit power. Each synchronous pulley 5 performs a different role, ensuring stable and efficient power transmission throughout the entire device. One end of the synchronous pulley 5 is fixedly connected to one end of the rope winch 17. This allows the rotation of the rope winch 17 to be directly transmitted to the belt system via the synchronous pulley 5, ensuring that the rotation of the rope winch 17 can be controlled through this mechanical transmission.

[0040] Another synchronous pulley 5 is rotatably connected to one side of the protective housing 3. A timing belt is sleeved around the outer walls of both synchronous pulleys 5. The precise fit of the timing belt with the synchronous pulleys 5 ensures efficient power transmission. This rotational connection of the synchronous pulleys 5 provides a mechanical linkage that prevents power transmission from being disrupted by external factors, ensuring smooth operation of the equipment.

[0041] Pulley 1 (7), connected to synchronous pulley 5, is mounted on the end face of synchronous pulley 5 and connected to pulley 2 (8) via a belt. Pulley 2 (8) is fixed to the inner wall of protective box 4 and connected to pulley 1 (7) via a belt. This belt system not only transmits power but also provides cushioning and shock absorption. The use of a belt reduces direct metal contact, reduces mechanical wear, and improves the durability and stability of the device over extended use.

[0042] Please see the attached Figure 2 -Attached Figure 3 The wire management assembly includes a screw rod 9, which is rotatably connected to one end of the frame 1, and a stabilizing wheel 10 is fixedly connected to one end of the frame 1. The outer wall of the stabilizing wheel 10 is slidably connected to a disk device 11, and the disk device 11 is threadedly connected to the outer wall of the screw rod 9. A turbofan 13 is installed at one end of the outer wall of the screw rod 9. The screw rod 9 passes through the blower box 6 and is fixedly connected to one end of the pulley 8.

[0043] Specifically, the design of screw rod 9 allows it to rotate freely on frame 1, enabling precise displacement control of screw rod 9 during operation. A stabilizing wheel 10 is also fixedly connected to one end of frame 1. This stabilizing wheel 10, aligned perpendicularly to screw rod 9, maintains the stability and support of the loading device 11. The outer wall of stabilizing wheel 10 is slidably connected to the loading device 11, allowing the loading device 11 to move smoothly up and down on the outer wall of stabilizing wheel 10.

[0044] The threaded connection between the winding mechanism 11 and the screw 9 ensures precise linear displacement of the winding mechanism 11 along the outer wall of the screw 9 as the screw 9 rotates. This threaded connection allows the winding mechanism 11 to move precisely laterally as the screw 9 rotates, effectively arranging and organizing the ropes on the capstan.

[0045] A turbofan 13 is mounted on one end of the screw 9. The combination of the turbofan 13 and the screw 9 ensures that rotation not only drives the upper disc 11 but also generates air flow. The design of the turbofan 13 helps direct airflow into the blower box 6, creating an air circulation system. This airflow system helps maintain a low temperature during operation, preventing overheating due to prolonged operation.

[0046] In order to ensure the stability of the cable management assembly, the screw rod 9 passes through the blower box 6 and is fixedly connected to one end of the pulley 2 8. This design of the screw rod 9 enables it to not only transmit rotational power, but also cooperate with other transmission components, further enhancing the stability and efficiency of the equipment.

[0047] Please see the attached Figure 5 -Attached Figure 6The power transmission component includes an energy storage group 18, which is installed on the top of the frame 1. The output end of the energy storage group 18 is provided with a lighting and heating mechanism. An outer box 19 is installed at one end of the frame 1. The inner wall of the outer box 19 is fixedly connected to a connector 21. An armature 24 is installed at one end of the connector 21. The outer wall of the connector 21 is rotatably connected to a rotor 22. A plurality of permanent magnets 23 are installed on the inner wall of the rotor 22. One end of the rotor 22 is fixedly connected to the rotor 22. A power line 25 is provided at one end of the armature 24. The power line 25 is connected to the input end of the energy storage group 18. The lighting and heating mechanism includes a lighting lamp 14 and a heating lamp 16. The lighting lamp 14 is installed on the top of the protective shell 3, and the heating lamp 16 is installed inside the protective shell 3. They are electrically connected to the energy storage group 18 in parallel.

[0048] Specifically, energy storage group 18 is installed on top of frame 1. As the power source for the entire device, it not only provides electricity but also stores excess energy generated during the operation of the electric winch. This stored energy can be used for functions such as lighting and heating, making it particularly crucial when no external power source is available.

[0049] The output end of the energy storage group 18 is connected to the lighting and heating mechanism. The lighting and heating mechanism consists of a lighting lamp 14 and a heating lamp 16. The lighting lamp 14 is installed on the top of the protective shell 3, while the heating lamp 16 is installed inside the protective shell 3. The lighting lamp 14 provides necessary lighting support to ensure that the ship can still operate in a low-light environment. The heating lamp 16 is used to maintain the temperature inside the device and heat the device in a cold environment to avoid problems such as sticky lubricating oil and stuck components due to low temperature. The lighting lamp 14 and the heating lamp 16 are connected in parallel to the energy storage group 18 to ensure that both can obtain the required electricity from the energy storage group 18 when needed, and can independently control the switch to avoid energy waste.

[0050] In order to achieve efficient power conversion and transmission, the power transmission component also includes the design of an armature 24, a rotor 22 and a permanent magnet 23. The outer box 19 is installed at one end of the frame 1, and a connector 21 is fixedly connected to the inner wall of the outer box 19. The armature 24 is installed at one end of the connector 21. The armature 24 and the rotor 22 are connected through the connector 21. A plurality of permanent magnets 23 are installed on the inner wall of the rotor 22. The function of these permanent magnets 23 is to provide a stable magnetic field. The rotor 22 is connected to the outer wall of the connector 21 through rotation. The change in the magnetic field during rotation will induce current in the armature 24, thereby providing power to the energy storage group 18, achieving the effect of power generation.

[0051] A power cable 25 is attached to one end of the armature 24, connected to the input of the energy storage group 18. This cable transmits the current sensed by the armature 24 to the energy storage group 18, enabling energy recovery and storage. This design allows the device to convert mechanical energy generated during operation into electrical energy and store it for later use. Whether during winch operation or when other equipment is running, excess energy can be effectively stored and utilized.

[0052] The design of this power transmission component, through the interaction between permanent magnets 23 and armature 24, enables efficient electrical energy conversion during device operation, while energy storage group 18 ensures system self-sufficiency. The addition of lighting lamps 14 and heating lamps 16 allows the device to continue operating in extreme environments, preventing performance degradation caused by low temperatures or insufficient light.

[0053] While 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 these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
