Description

Technical Field

[0001] This utility model relates to the field of rotary drive technology, specifically a vertical rotary drive device. Background Technology

[0002] A rotary drive, also known as a rotary reducer or turntable reducer, is a full-circumference rotary reduction transmission mechanism that integrates a drive power source. It uses a slewing bearing as the driven component and attachment component of the mechanism. By attaching the driving component, drive source, and housing to one of the inner and outer rings, and the other ring as the driven component and connecting base, it integrates rotation, reduction, and drive functions into one.

[0003] A patent with publication number CN209587053U is known to disclose a vertical rotary drive device. Its background art addresses the problem that "due to the existence of overturning moment and radial runout of the gear ring, radial extrusion occurs between the connecting gear and the external gear ring of the external gear slewing bearing, leading to a reduction in the overlap ratio of the gear transmission and a decrease in transmission accuracy; simultaneously, excessive radial extrusion force directly acts on the shaft at one end of the reducer connected to the connecting gear, causing the shaft to be subjected to shear stress, making it highly susceptible to breakage." The technical solution to this problem is described as follows: "It includes: a housing, a slewing bearing, a rotating shaft, a drive gear, and a power element. One end of the rotating shaft is connected to the power element, and the other end is fitted with a hole fixed to the inner hole of the drive gear. The end of the drive gear away from the power element is provided with a support assembly, which includes a support bearing and a support seat."

[0004] However, during the implementation of the relevant technologies, the following problems were found with the above-mentioned technical solutions: During use, it is difficult to buffer and filter vibrations in the drive motor. Because external equipment and the motor generate a certain vibration amplitude during operation, long-term use can easily damage the device, affecting power transmission and the overall service life of the device. Furthermore, it is difficult to dissipate heat and cool the motor, easily causing the motor temperature to become too high, affecting the performance. Therefore, a vertical rotary drive device is proposed. Utility Model Content

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1 to 4 This utility model provides a vertical rotary drive device, including a base 1, a protective shell 2, and a rotary bearing 3. The protective shell 2 is fixedly installed on the top of the base 1, and the rotary bearing 3 is rotatably connected to the top of the base 1 and extends out of the protective shell 2. It also includes a protective component 4 and a drive mechanism 5. The protective component 4 is located on the top of the base 1 and is used to protect the drive mechanism 5. The drive mechanism 5 is located inside the protective component 4 and is used to drive the rotary bearing 3. The protective component 4 includes a shock-absorbing mechanism 42 and a heat dissipation mechanism 43, which are used to filter vibration and cool down the drive mechanism 5, respectively. With the above configuration, in use, the drive mechanism 5 drives the rotary bearing 3 to rotate. During the driving process, the shock-absorbing mechanism 42 filters vibration of the drive mechanism 5, and the heat dissipation mechanism 43 cools down the drive mechanism 5 to ensure the operational stability of the drive mechanism 5.

[0017] As one embodiment of this utility model, refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 The protective component 4 also includes a support plate 44 and a protective box 41. The support plate 44 is fixedly installed on the top of the base 1, and the protective box 41 is fixedly installed on the top of the support plate 44. The shock absorption mechanism 42 and the heat dissipation mechanism 43 are both located inside the protective box 41. Through the above-mentioned arrangement, the support plate 44 is set to facilitate the installation of the protective component 4 on the base 1, ensuring the stability of the protective component 4 in use. By setting the protective box 41, it is convenient to protect the drive mechanism 5, the shock absorption mechanism 42 and the heat dissipation mechanism 43, and prevent the external environment from affecting their operation.

[0018] As one embodiment of this utility model, refer to Figure 3 and Figure 4The damping mechanism 42 includes a set of dampers 421, two sets of springs 422, two guide rails 423, a connecting plate 424, a vibration sensor 425, and an audible and visual alarm 426. The dampers 421 are fixedly installed on one side of the inner wall of the protective box 41, the springs 422 are fixedly installed on one side of the inner wall of the protective box 41, the guide rails 423 are fixedly installed on both sides of the inner wall of the protective box 41, and the connecting plate 424 is slidably connected to the guide rails 423 via a slider. The connecting plate 424 is connected to one end of the dampers 421 and the springs 422. The vibration sensor 425 is mounted on the drive mechanism 5, and the audible and visual alarm 426 is fixedly mounted on the support plate 44. Through the above arrangement, the vibration force generated by the operation of the drive mechanism 5 can be transmitted to the connecting plate 424. The connecting plate 424 slides along the guide rail 423 via the slider, pressing the spring 422 and the damper 421. At the same time, the damper 421 and the spring 422 work together to filter the vibration of the drive mechanism 5, so as to prevent the drive mechanism 5 from vibrating too much and causing shaking that affects the driving effect. This effectively improves the transmission effect and stability of the device. The vibration sensor 425 facilitates real-time monitoring of the vibration of the drive mechanism 5. If the vibration amplitude and frequency of the drive mechanism 5 continue to be too large, and the damper 421 and the spring 422 cannot guarantee the stability of the drive mechanism 5, the feedback is sent to the controller of the device, and the controller controls the audible and visual alarm 426 to sound an alarm to remind personnel to maintain it in time.

[0019] As one embodiment of this utility model, refer to Figure 1 , Figure 2 , Figure 3 and Figure 4The heat dissipation mechanism 43 includes a heat sink 431, a cooling fan 432, a filter plate 433, a filter screen 434, and a temperature sensor 435. The heat sink 431 is fixedly installed on the top of the protective housing 41. The cooling fan 432 is fixedly installed inside the heat sink 431. The filter plate 433 is fixedly installed inside the heat sink 431 and located above the cooling fan 432. The filter screen 434 is fixedly installed on the top of the heat sink 431. The temperature sensor 435 is fixedly installed on one side of the inner wall of the protective housing 41. A heat dissipation hole is provided on one side of the protective housing 41. Through the above arrangement, during the operation of the drive mechanism 5, the temperature sensor 435 detects the temperature of the drive mechanism. The temperature of the drive mechanism 5 is monitored. When the temperature is too high, feedback is sent to the controller of the device. The controller then controls the cooling fan 432 to blow air into the protective box 41 to cool the drive mechanism 5. This allows the heat from the drive mechanism 5 to be discharged through the heat dissipation holes on one side of the protective box 41, thereby achieving the effect of cooling the drive mechanism 5 and preventing the overheating of the drive mechanism 5 from affecting its use. This effectively improves the operational stability of the drive mechanism 5. Furthermore, when the cooling fan 432 blows air, the air drawn in by the cooling fan 432 can be filtered sequentially by the filter screen 434 and the filter plate 433 to prevent dust particles from entering the protective box 41 and affecting the operation of the drive mechanism 5.

[0020] As one embodiment of this utility model, refer to Figure 2 The drive mechanism 5 includes a motor 51, a coupling 52, a reducer 53, a helical gear 54, and a helical ring gear 55. The motor 51 is fixedly mounted on one side of the connecting plate 424. The coupling 52 is fixedly connected to the output end of the motor 51. The reducer 53 is fixedly mounted on the bottom of the protective box 41. The coupling 52 rotatably passes through the protective box 41 and connects to the input end of the reducer 53. The output end of the reducer 53 rotatably passes through the protective shell 2. The helical gear 54 is fixedly mounted on the output end of the reducer 53. The helical ring gear 55 is fixedly mounted on the surface of the slewing bearing 3 and meshes with the helical gear 54. The vibration sensor 425 is fixedly mounted on... The surface of the motor 51 includes a universal coupling 52. With the above configuration, when driving the slewing bearing 3, the motor 51 drives the coupling 52 to rotate, and the coupling 52 drives the reducer 53 to run. The reducer 53 drives the helical gear 54 to rotate, which in turn drives the helical gear ring 55 that meshes with it to rotate, thereby causing the slewing bearing 3 to rotate. Moreover, by using the meshing transmission of the helical gear 54 and the helical gear ring 55, compared with the traditional spur gear transmission, it has excellent meshing performance, high load-bearing capacity and low noise, which makes it easier to ensure the operational stability of the device and extend the service life of the device.

[0021] Working principle: When driving the slewing bearing 3, the motor 51 drives the coupling 52 to rotate, and the coupling 52 drives the reducer 53 to run, which in turn drives the helical gear 54 to rotate. This causes the helical gear 54 to drive the helical ring gear 55 that meshes with it to rotate, thereby causing the slewing bearing 3 to rotate. Compared with the traditional spur gear transmission, the transmission through the meshing of the helical gear 54 and the helical ring gear 55 has excellent meshing performance, high load-bearing capacity and low noise. The vibration force generated by the operation of the drive mechanism 5 can be transmitted to the connecting plate 424, causing the connecting plate 424 to slide along the guide rail 423 via the slider, and to compress the spring 422 and the damper 421. At the same time, under the combined action of the damper 421 and the spring 422, the drive mechanism 5 can be subjected to vibration filtering treatment to prevent the drive mechanism 5 from vibrating too much and causing shaking that affects the driving effect. This effectively improves the transmission effect and operational stability of the device. Furthermore, the vibration sensor 425 facilitates real-time monitoring of the vibration magnitude of the drive mechanism 5. If the vibration amplitude and frequency of the drive mechanism 5 continue to be too large, and the damper 421 and the spring 422 are unable to guarantee the stability of the drive mechanism 5, the audible and visual alarm 426 will sound an alarm to remind personnel to perform timely maintenance. During the operation of the drive mechanism 5, the temperature of the drive mechanism 5 is detected by the temperature sensor 435. When the temperature is too high, the cooling fan 432 blows air into the protective box 41 to cool the drive mechanism 5 and dissipate heat from the protective box 41. This achieves the effect of cooling the drive mechanism 5 and prevents the drive mechanism 5 from operating at too high a temperature, which would affect its use. This effectively improves the operational stability of the drive mechanism 5. Furthermore, when the cooling fan 432 blows air, the air drawn in by the cooling fan 432 can be filtered sequentially by the filter screen 434 and the filter plate 433 to prevent dust particles from entering the protective box 41 and affecting the operation of the drive mechanism 5.

[0022] It should be noted that this device is controlled by connecting to an external PLC controller, and the vibration sensor 425, the audible and visual alarm 426, the temperature sensor 435, and the motor 51 in this device are all electrically connected to the PLC controller. Those skilled in the art can select the model and type of the components according to their usage requirements and complete the debugging of the components to ensure the normal operation of this device. This is a mature technology that has been disclosed in the prior art and will not be described in detail here.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
