Description

Technical Field

[0001] This utility model relates to the field of mechanical power transmission and control technology, and in particular to a manual power switching device. Background Technology

[0002] In modern industrial production, machinery, and various power-driven equipment, the flexibility and controllability of power transmission are crucial performance indicators. Many devices require both efficient and stable power output through electric drive during normal operation to meet the demands of large-scale, continuous production, and the ability to quickly switch to manual drive mode in special circumstances, such as electric system failures, maintenance, or when precise manual control is needed, to ensure continuous operation or safe operation. Traditional power units often only support either electric or manual drive. While electric drive provides greater power and higher efficiency, it often stops immediately in the event of power failures or motor damage, affecting production continuity, and the restart and repair process is complex. Manual drive alone suffers from limited power and low operational efficiency, making it difficult to meet the needs of large-scale production. Therefore, developing a power unit capable of flexibly switching between electric and manual drive modes is of significant practical importance. However, some existing manual switching power units suffer from complex structures, inconvenient switching operations, and unstable power transmission during switching, affecting the reliability and practicality of the device.

[0003] Chinese patent discloses an electric roller shutter door drive device (publication number: CN 217632215 U). The main shaft has a cylindrical structure, and the two ends of the main shaft are directly fixed to the wall columns of the building doorway through special connectors. The reel is circular and supported on the main shaft by bearings or sliding sleeves. The reel can rotate around the main shaft. The upper part of the roller shutter is connected to the arc surface of the outer circle of the reel. The reel winds the roller shutter. The feature is that a gear reel is set on the main shaft. However, most of these power devices can only use electric or manual drive. Electric drive is prone to equipment shutdown in case of emergencies and is complicated to repair. Manual drive has limited power and low efficiency. Moreover, some switchable devices have problems such as complex structure, inconvenient operation, and unstable power transmission during switching. It is difficult to meet the equipment's need for flexible and stable power supply under different working conditions. Therefore, a manual switching power device is needed. Utility Model Content

[0004] The purpose of this utility model is to solve the problems that most traditional power devices in the prior art can only use electric or manual drive. Electric drive is prone to equipment shutdown in case of emergencies and is complicated to repair. Manual drive has limited power and low efficiency. In addition, some switchable devices have problems such as complex structure, inconvenient operation and unstable power transmission during switching. They are difficult to meet the equipment's demand for flexible and stable power supply under different working conditions. Therefore, a manual switching power device is proposed.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: The manual switching power device of this utility model includes a drive housing device, characterized in that: the drive housing device includes a transmission rod, the transmission rod extends in the left and right direction and has a left linkage housing and a right drive housing respectively passing through its two ends, the right drive housing includes a right mounting bracket, the right mounting bracket includes a motor mounting plate, a reduction motor is mounted on the motor mounting plate, one end of the reduction motor is connected to a motor shaft, one end of the motor shaft is connected to a right bearing seat, the other end of the right bearing seat is connected to the transmission rod, a handwheel is provided on the transmission rod near the right bearing seat, and a shift fork is provided on one side of the sliding coupling. This design incorporates a drive housing, with the transmission rod serving as the key component for power transmission. The left and right linkage housings and the right drive housing are arranged around the transmission rod, resulting in a rational overall structural layout that provides a stable framework for power transmission and switching. The geared motor enables the device to be electrically driven. The connection between the motor shaft, the right bearing housing, and the transmission rod allows the power output from the geared motor to be transmitted to the transmission rod, achieving power transmission in electric mode. The handwheel provides manual operation; when manual control is required, the power can be manually transmitted by turning the handwheel. The presence of the sliding coupling and the shift fork provides the necessary structural foundation for switching between manual and electric modes. The shift fork controls the movement of the sliding coupling, thereby changing the power transmission path.

[0006] Preferably, the left linkage housing includes a left mounting bracket, on which a left bearing seat is provided. A left transmission gear is provided on one side of the left bearing seat, and both the left bearing seat and the left transmission gear are associated with one end of the transmission rod. The left linkage housing is supported and fixed by the left mounting bracket, ensuring the stability of the overall structure of the left linkage housing. The left bearing seat can support and position the transmission rod, reducing friction and shaking during rotation and improving the stability and efficiency of transmission. The left transmission gear is associated with the transmission rod, enabling the left transmission gear to transmit and cooperate with the transmission rod. When the left transmission gear meshes with other gears, it can change the direction and speed of power transmission, enriching the power transmission function of the device. The left linkage housing, the right drive housing, and the transmission rod together constitute a complete power transmission system. The various components cooperate with each other to achieve effective power transmission and distribution.

[0007] Preferably, the outer peripheral surface of the handwheel is provided with an anti-slip coating, which is a grid-like groove.

[0008] The anti-slip coating on the outer circumference of the handwheel increases the friction between the user's hand and the handwheel, preventing slippage during rotation and ensuring accurate and stable control. The grid-like groove design of the anti-slip coating not only provides excellent anti-slip properties but is also relatively simple to manufacture and implement without adding excessive cost or complexity. The anti-slip function improves the safety and convenience of device operation, making manual operation of the power unit easier and more reliable, reducing operational errors and safety hazards caused by slippage.

[0009] Preferably, a right drive gear is provided on one side of the handwheel, and the right drive gear is correspondingly arranged with the left drive gear. The corresponding arrangement of the right drive gear and the left drive gear provides the conditions for meshing transmission between the two gears. When the right drive gear meshes with the left drive gear, power transmission and conversion can be realized, transmitting the power generated by the right drive housing or manual operation to the left linkage housing, thus expanding the power transmission path of the device.

[0010] Preferably, both the left and right drive gears are integrally forged 42CrMo gears with a surface hardness of HRC58-62. The integral forging of 42CrMo material gives the left and right drive gears high strength and toughness, enabling them to withstand large loads and impacts, ensuring that the gears are not easily damaged during long-term use, thus improving their service life and reliability. Gears with a surface hardness of HRC58-62 have good wear resistance, reducing tooth surface wear during gear meshing, maintaining gear accuracy and transmission efficiency, and lowering the failure rate caused by wear.

[0011] Preferably, the outer wall of the motor shaft is provided with keyways at both ends, and a flat key is provided on the keyway. The keyways and flat keys at both ends of the outer wall of the motor shaft enable a reliable connection between the motor shaft and related components (such as the right bearing housing), ensuring that the motor shaft can accurately transmit torque to the connected components when transmitting power, preventing relative slippage between components, and ensuring the efficiency and accuracy of power transmission. The keyway and flat key connection method has a simple structure, is easy to install and disassemble, facilitates the assembly and maintenance of the device, and reduces the maintenance cost and difficulty of the device.

[0012] The advantages of this utility model are: This utility model's manual power switching device boasts strong functionality and practicality. Through a rationally arranged drive housing, with the transmission rod as the core power transmission component, and left and right linkage housings and the right drive housing arranged around it, a stable and efficient power transmission framework is constructed. In electric mode, the geared motor connects to the transmission rod via the motor shaft and the right bearing seat, stably transmitting power to the transmission rod to achieve efficient electric drive and meet routine work requirements. The handwheel provides manual operation; in special working conditions, the transmission rod can be directly driven by turning the handwheel, ensuring the equipment can still operate in the event of an electric failure, enhancing adaptability to various working conditions. The sliding coupling and shift fork are key to mode switching; the shift fork controls the movement of the sliding coupling, flexibly changing the power transmission path to achieve convenient and reliable switching between electric and manual modes. The anti-slip coating (grid-like grooves) on the outer periphery of the handwheel increases hand friction, preventing slippage and ensuring accurate and safe manual operation. The right drive gear is set to correspond with the left drive gear, creating conditions for meshing transmission. By controlling meshing / disengagement, the direction and mode of power transmission can be changed, expanding the transmission path and enhancing applicability and versatility. The keyway and flat key on the outer wall of the motor shaft connect related components (such as the right bearing housing), ensuring accurate torque transmission, preventing component slippage, improving transmission efficiency and accuracy, and having a simple structure that is easy to assemble and maintain, reducing maintenance costs and failure risks, and ensuring the normal operation of the device.

Example

[0019] Please see Figure 1-3 As shown, a manually switchable power device includes a drive housing device, characterized in that: the drive housing device includes a transmission rod 4, the transmission rod 4 extends in a left-right direction and has a left linkage housing and a right drive housing respectively passing through its two ends, the right drive housing includes a right mounting bracket 5, the right mounting bracket 5 includes a motor mounting plate 14, a reduction motor 13 is mounted on the motor mounting plate 14, one end of the reduction motor 13 is connected to a motor shaft 10, one end of the motor shaft 10 is connected to a right bearing seat 8, the other end of the right bearing seat 8 is connected to the transmission rod 4, a handwheel 6 is provided on the transmission rod 4 near the right bearing seat 8, and a shift fork 12 is provided on one side of the sliding coupling 11. This design incorporates a drive housing, with the transmission rod 4 serving as the key component for power transmission. The left and right linkage housings and the right drive housing are arranged around the transmission rod 4, resulting in a rational overall structural layout that provides a stable framework for power transmission and switching. The geared motor 13 enables the device to be electrically driven. The connection between the motor shaft 10, the right bearing seat 8, and the transmission rod 4 allows the power output from the geared motor 13 to be transmitted to the transmission rod 4, achieving power transmission in electric mode. The handwheel 6 provides manual operation; when manual control is required, power transmission can be achieved by turning the handwheel 6. The sliding coupling 11 and the shift fork 12 provide the necessary structural foundation for switching between manual and electric modes. The shift fork 12 controls the movement of the sliding coupling 11, thereby changing the power transmission path.

[0020] In this embodiment, the left linkage housing includes a left mounting bracket 1, on which a left bearing seat 2 is provided. A left transmission gear 3 is provided on one side of the left bearing seat 2. Both the left bearing seat 2 and the left transmission gear 3 are associated with one end of the transmission rod 4. The left linkage housing is supported and fixed by the left mounting bracket 1, ensuring the stability of the overall structure of the left linkage housing. The left bearing seat 2 can support and position the transmission rod 4, reducing friction and shaking of the transmission rod 4 during rotation, and improving the stability and efficiency of transmission. The left transmission gear 3 is associated with the transmission rod 4, enabling the left transmission gear 3 to transmit and cooperate with the transmission rod 4. When the left transmission gear 3 meshes with other gears, it can change the direction and speed of power transmission, enriching the power transmission function of the device. The left linkage housing, the right drive housing, and the transmission rod 4 together constitute a complete power transmission system. The various components cooperate with each other to achieve effective power transmission and distribution.

[0021] In this embodiment, the outer peripheral surface of the handwheel 6 is provided with an anti-slip coating 15, which is a grid-shaped groove.

[0022] The anti-slip coating 15 on the outer circumference of the handwheel 6 increases the friction between the user's hand and the handwheel 6, preventing slippage during rotation and ensuring accurate and stable control. The grid-like groove design of the anti-slip coating 15 not only provides excellent anti-slip performance, but also offers a relatively simple structure that is easy to manufacture and implement without adding excessive cost or complexity. The anti-slip function improves the safety and convenience of device operation, making it easier and more reliable for users to manually operate the power unit, reducing operational errors and safety hazards caused by slippage.

[0023] In this embodiment, a right drive gear 7 is provided on one side of the handwheel 6, and the right drive gear 7 is correspondingly arranged with the left drive gear 3. The corresponding arrangement of the right drive gear 7 and the left drive gear 3 provides the conditions for meshing transmission between the two gears. When the right drive gear 7 meshes with the left drive gear 3, power transmission and conversion can be realized, transmitting the power generated by the right drive housing or manual operation to the left linkage housing, thus expanding the power transmission path of the device.

[0024] In this embodiment, both the left drive gear 3 and the right drive gear 7 are integrally forged 42CrMo gears with a surface hardness of HRC58-62. The integral forging of 42CrMo material gives the left drive gear 3 and right drive gear 7 high strength and toughness, enabling them to withstand large loads and impacts, ensuring that the gears are not easily damaged during long-term use, thus improving their service life and reliability. Gears with a surface hardness of HRC58-62 have good wear resistance, reducing tooth surface wear during gear meshing, maintaining gear accuracy and transmission efficiency, and lowering the failure rate caused by wear.

[0025] In this embodiment, keyways are provided at both ends of the outer wall of the motor shaft 10, and flat keys 9 are provided on the keyways. The keyways and flat keys 9 at both ends of the outer wall of the motor shaft 10 enable a reliable connection between the motor shaft 10 and related components (such as the right bearing housing 8), ensuring that the motor shaft 10 can accurately transmit torque to the connected components when transmitting power, preventing relative slippage between components, and ensuring the efficiency and accuracy of power transmission. The connection method of keyways and flat keys 9 has a simple structure, is easy to install and disassemble, facilitates the assembly and maintenance of the device, and reduces the maintenance cost and difficulty of the device.

[0026] The implementation principle of this embodiment is as follows: Electric Mode: When the device is in electric mode, the geared motor 13 starts working, and the motor shaft 10 rotates under the drive of the geared motor 13. Since one end of the motor shaft 10 is connected to the right bearing seat 8, and the other end of the right bearing seat 8 is connected to the transmission rod 4, the rotational motion of the motor shaft 10 is transmitted to the transmission rod 4 through the right bearing seat 8, causing the transmission rod 4 to rotate with the rotation of the motor shaft 10. The rotation of the transmission rod 4 then transmits power to other connected working parts, realizing power transmission and operation under electric drive. At this time, the sliding coupling 11 is in the connected state (controlled to be in the appropriate position by the shift fork 12), ensuring smooth power transmission between the motor shaft 10 and the transmission rod 4. The right transmission gear 7 and the left transmission gear 3 are in the disengaged state, avoiding interference from the manual transmission gear to the electric power transmission.

[0027] Manual Mode: When switching to manual mode, the user operates manually by turning handwheel 6. The rotation of handwheel 6 controls the axial movement of sliding coupling 11 via shift fork 12, disconnecting sliding coupling 11 from motor shaft 10 and transmission rod 4 (i.e., disconnecting the electric power transmission path). Simultaneously, the rotation of handwheel 6 drives transmission rod 4 to rotate. Since handwheel 6 is located on the transmission rod 4 near the right bearing seat 8, its rotation is directly transmitted to transmission rod 4. During the rotation of transmission rod 4, right transmission gear 7 rotates along with it, and through meshing with left transmission gear 3 (ensuring the right transmission gear 7 and left transmission gear 3 are in corresponding meshing positions during switching), manual power is transmitted from transmission rod 4 to left transmission gear 3. Then, through the connection between left transmission gear 3 and transmission rod 4, power is transmitted to the entire power transmission system, achieving manual drive power transmission and operation.
