[0048] The electric and manual integrated drive mechanism of this embodiment will be described below with reference to the accompanying drawings.

Figure 1 As shown, the electric and manual integrated drive mechanism includes: a base 1, a pair of reducer assemblies 2 installed on the base 1, a pair of drive motors 4 for driving the reducer assembly 2 and a manual mechanism assembly 3 installed on the base 1, the manual mechanism assembly 3 is connected to the pair of reducer assemblies 2, and is used to manually drive the reducer in the reducer assembly 2 to operate when the drive motor 4 is powered off or fails.

[0050] The transmission reducer driving mode is that the drive motor 4 directly drives the reducer, and in this embodiment, a manual mechanism component 3 is also provided between the drive motor 4 and the reducer assembly 2 to realize the electric and manual integration of the drive mechanism. Specifically, in order to improve the load driving efficiency, the drive motor 4 can usually be used to drive the reducer to realize the driving of the load, but when there is a power outage or equipment failure such as a drive motor failure, the manual mechanism component 3 can be used to manually drive the reducer in the reducer assembly 2 to operate, so as to solve the problem that the load cannot be driven.

[0051] like Figure 2 As shown, the manual mechanism assembly 3 includes: a lifting bracket assembly 31 and a supporting frame assembly 32 installed on the base 1, a worm 33 arranged on the lifting bracket assembly 31 and the supporting frame assembly 32, a first hand wheel 34 and a second hand wheel 35 respectively arranged at both ends of the worm 33, and a first worm wheel 36 and a second worm wheel 37. Among them, the first worm wheel 36 and the second worm wheel 37 are arranged between the lifting bracket assembly 31 and the supporting frame assembly 32, and are respectively connected to the motor shaft of the corresponding driving motor 4, and the first worm wheel 36 and the second worm wheel 37 are also respectively connected to the reducer in the corresponding reducer assembly 2.

[0052] Specifically, a meshing portion is provided on the worm 33. When the drive motor 4 is powered off or fails, the lifting bracket assembly 31 is moved downward so that the meshing portion on the worm 33 meshes with the first worm gear 36 and the second worm gear 37, and the worm 33 is shaken by the first hand wheel 34 and the second hand wheel 35 to drive the first worm gear 36 and the second worm gear 37 to rotate, thereby driving the reducer in the reducer assembly 2 to operate; when the drive motor 4 is operating normally, the lifting bracket assembly 31 is moved upward so that the meshing portion on the worm 33 disengages from the first worm gear 36 and the second worm gear 37, and the first worm gear 36 and the second worm gear 37 are driven to rotate by the corresponding drive motor 4 to drive the reducer in the reducer assembly 2 to operate.

[0053] In this embodiment, a pair of drive motors 4 are connected to the first worm gear 36 and the second worm gear 37 respectively, and the first worm gear 36 and the second worm gear 37 are connected to the corresponding reducers in the reducer assembly 2 respectively. When the drive motor 4 works normally, the motor shaft of the drive motor 4 drives the first worm gear 36 and the second worm gear 37 to rotate respectively, and the rotation of the first worm gear 36 and the second worm gear 37 drives the corresponding reducer in the reducer assembly 2 to operate. When the drive motor 4 is powered off or fails, the manual mechanism assembly 3 is used to manually drive the first worm gear 36 and the second worm gear 37 to rotate, so as to drive the reducer in the reducer assembly 2 to operate.

[0054] Specifically, when the driving motor 4 is powered off or fails, the hand wheel can be rotated manually to drive the worm 33 to rotate. The rotation of the worm 33 drives the worm wheel to rotate, and then drives the reducer to rotate.

[0055] like Figure 3 As shown, the lifting bracket assembly 31 includes: an outer frame 310, a lifting block 311, a locking screw 312 and a wedge block 313. The outer frame 310 is arranged on the base 1, and a first through hole is opened on one side of the outer frame 310; the lifting block 311 is arranged in the outer frame 310 and is slidably connected with the outer frame 310; the locking screw 312 passes through the first through hole and is used to lock the lifting block 311; the wedge block 313 is connected to the bottom end of the lifting block 311 and the base 1 respectively.

[0056] In this embodiment, the top of the lifting block 311 is connected to the worm 33, the wedge block 313 moves backward, and the lifting block 311 drives the worm 33 to move downward, so that the meshing portion of the worm 33 meshes with the first worm wheel 36 and the second worm wheel 37, and the worm 33 is shaken by the first hand wheel 34 and the second hand wheel 35 to drive the first worm wheel 36 and the second worm wheel 37 to rotate, thereby driving the reducer in the reducer assembly 2 to operate, so as to drive the corresponding load; the wedge block 313 moves forward, the wedge block 313 lifts the lifting block 311, drives the meshing portion of the worm 33 to disengage from the first worm wheel 36 and the second worm wheel 37, and drives the first worm wheel 36 and the second worm wheel 37 to rotate through the corresponding drive motor 4, so as to drive the reducer in the reducer assembly 2 to operate. Therefore, the present invention can realize both manual and electric driving modes of the driving mechanism, and can effectively solve the problem that the reducer cannot operate and the corresponding load cannot be driven when power failure or equipment failure occurs.

[0057] Please continue to refer to Figure 3 The lifting bracket assembly 31 further includes: a shaft frame 314, a lifting shaft 315 and a lifting wheel 316. In this embodiment, the shaft frame 314 is mounted on the base 1, and a second through hole is opened at the top of the shaft frame 314 in the horizontal direction; the first end of the lifting shaft 315 is connected to the lifting wheel 316, and the second end of the lifting shaft 315 passes through the second through hole and is set on the wedge block 313 through the shaft pressure plate 317.

[0058] When the driving motor 4 is powered off or fails, the lifting wheel 316 is rotated to drive the wedge block 313 to move backward through the lifting shaft 315, so that the lifting block 311 drives the worm 33 to move downward to achieve manual drive; when the driving motor 4 is working normally, the lifting wheel 316 is rotated to drive the wedge block 313 to move forward through the lifting shaft 315, so that the lifting block 311 drives the worm 33 to move upward to achieve motor drive.

[0059] In this embodiment, the second end of the lifting shaft 315 is spherical, and the second end of the lifting shaft 315 is matched with a groove formed at a corresponding position on the wedge block 313 and can rotate in the groove.

[0060] Specifically, the lifting shaft 315 is threadedly connected to the shaft frame 314. After the lifting shaft 315 is screwed into the threaded hole of the shaft frame 314, the lifting wheel 316 is shaken to drive the lifting shaft 315 to move linearly in the horizontal direction, thereby driving the wedge block 313 to move forward and backward, and then realizing motor drive and manual drive.

[0061] Please continue to refer to Figure 3The lifting bracket assembly 31 also includes: a first bearing sleeve 318, a first bearing 319 and a first bearing pressure plate 320. The first bearing sleeve 318 is arranged at the top of the lifting block 311; the first bearing 319 is installed in the first bearing sleeve 318, and one end of the worm 33 passes through the first bearing 319 and is connected to the first hand wheel 34; the first bearing pressure plate 320 is sleeved on the worm 33 and is used to tighten the first bearing 319.

[0062] Specifically, when the driving motor 4 is powered off or fails, the lifting bracket assembly 31 is moved down so that the meshing portion on the worm 33 meshes with the first worm wheel 36 and the second worm wheel 37. In order to enable the worm 33 to be shaken by the first hand wheel 34 and the second hand wheel 35, a bearing assembly can be set at the top of the lifting block 311, and then one end of the worm 33 is inserted through the first bearing 319 in the bearing assembly, so that the worm wheel can be driven to rotate by shaking the worm 33.

[0064] Similarly, another bearing assembly can be arranged at the top of the support frame assembly 32, and then the other end of the worm 33 is passed through the second bearing 323 in the bearing assembly, so that the worm wheel can be driven to rotate by shaking the worm 33.

[0065] It should be noted that in actual application, if a drive motor is required, the support frame assembly 32 can be used as a support, and the lifting block 311 can be driven upward by the lifting wheel 316, the lifting shaft 315 and the wedge block 313, so that the worm 33 and the first worm gear 36 and the second worm gear 37 are disengaged, and then the first worm gear 36 and the second worm gear 37 are driven to rotate by the corresponding drive motor 4 to drive the reducer in the reducer assembly 2 to operate.

[0066] As a specific example, Figure 5 and Figure 6As shown, when power failure or equipment failure occurs, the locking screw 312 is loosened, and the lifting shaft 315 is driven by the lifting wheel 316 to move the wedge block 313 backward. The wedge block 313 lowers the lifting block 311 and the worm 33 to achieve the engagement of the worm 33 with the first worm gear 36 and the second worm gear 37. Then, the lifting block 311 is locked by the locking screw 312, and the reducer assembly 2 is manually driven to operate by the first hand wheel 34 and the second hand wheel 35 at both ends of the worm 33. When the drive motor 4 is used for driving, the locking screw 312 is loosened, and the lifting shaft 315 is driven by the lifting wheel 316 to move the wedge block 313 forward. The wedge block 313 lifts the lifting block 311 to achieve the disengagement of the worm 33 and the first worm gear 36 and the second worm gear 37. After the worm 33 and the first worm gear 36 and the second worm gear 37 are completely disengaged, the locking screw 312 is used to lock the lifting block 311.
