Embodiment 1

[0024] see Figure 1-4 , the present embodiment provides a motor-driven failure emergency device, including a device housing 1 and a drive motor 3 fixedly installed inside the device housing 1, and a No. 1 rotating shaft 6 is fixedly installed on the output shaft of the drive motor 3, so The other end of the No. 1 rotating shaft 6 is connected with a machine 2, and a failure emergency mechanism acting on the drive motor 3 is installed in the device housing 1;

[0025] The failure emergency mechanism includes a No. 1 gear 5, an emergency motor 4, a No. 2 rotating shaft 9 and a control mechanism. The No. 1 gear 5 is fixedly installed on the No. 1 rotating shaft 6, and the emergency motor 4 is fixedly installed on the device housing 1 The inside and the output shaft of the emergency motor 4 are fixedly installed with the No. 2 gear 7 meshing with the No. 1 gear 5. The No. 2 rotating shaft 9 is rotatably installed in the inside of the device housing 1 and the No. 2 rotating shaft ...

Embodiment 2

[0035] When the rotating disk 10 rotates, it will constantly rub against the control assembly 24. After a long period of use, the rotating disk 10 and the control assembly 24 will cause the device to malfunction due to wear and tear. In order to solve this problem, this embodiment is based on the first embodiment A further improvement on the above, the improvement is: the top of the control assembly 24 is rotatably installed with a roller 26, so that the sliding friction between the rotating disk 10 and the control assembly 24 can be converted into friction between the roller 26 and the rotating disk 10 Rolling friction, thereby greatly reducing the wear of the rotating disk 10 and the control assembly 24.

Abstract

The invention discloses a motor drive fault emergency device, which comprises a device shell and a drive motor fixedly installed in the device shell, wherein a first rotating shaft is fixedly installed on the output shaft of the drive motor, the other end of the first rotating shaft is connected with a machine, a fault emergency mechanism acting on the drive motor is mounted in the device shell, and comprises a first gear, an emergency motor, a second rotating shaft and a control mechanism, and the control mechanism comprises a rotating disc, a sliding block, a rotating frame, a long rod and asecond switch. According to the invention, by means of the fault emergency mechanism, when the drive motor breaks down, the machine can continue to keep running, so that interference to the working process is avoided, and the problem that the service life of the machine is influenced by sudden stop of the machine can be avoided.

Description

technical field [0001] The invention relates to the technical field of motor drive, in particular to an emergency device for motor drive failure.
