The shearing device 400 is used for shearing the steel plate blank to be subjected to pendulum shear.

In an alternative embodiment, please refer to fig. 2 together, which is a schematic structural diagram of another pendulum shear fault detection system 10 provided in the embodiment of the present application. As shown in fig. 2, the power source device 100 may be an electric motor 1, and mainly provides a power source for the entire pendulum shear fault detection system.

And then, the determination result information and/or the sensing data (device information) are pushed to the client 305 through the network internet, so as to notify the relevant maintenance personnel to perform timely maintenance when the corresponding pendulum shear fault occurs.

Please refer to fig. 4, which is a flowchart illustrating a method for detecting a shear pendulum fault according to an embodiment of the present disclosure. The method shown in fig. 4 is applied to the shear pendulum fault detection system shown in fig. 1 or fig. 2, and comprises the following implementation steps:

s401, sensing data corresponding to each sensor in the pendulum shear fault detection system are obtained, wherein the sensing data comprise at least one of the following items: oil level data, oil temperature data, input shaft speed, transmission shaft amplitude and power output torque.

When the pendulum shear signal generated by the system is received, the pendulum shear fault detection system can be started, and then the sensing data of each sensor in the system is acquired. And the oil level data is the height of the oil level in the reduction gearbox 5 detected and collected by an oil level sensor 7 in the pendulum shear fault detection system. The oil level data is the oil temperature height in the reduction gearbox 5 detected and collected by an oil temperature sensor 8 in the system. The rotating speed of the input shaft is the rotating speed of the input shaft acquired by the rotating speed sensor 3 in the system. The amplitude of the transmission shaft is the amplitude value of the corresponding transmission shaft acquired by the acceleration sensor 4 in the system. The power output torque is the engine output torque measured by the torque sensor 19 in the system in real time.

S402, judging whether the sensing data meet preset fault detection conditions (also called fault detection standards).

The fault detection condition is set by the system in a self-defining way, and can include, but is not limited to, any one or combination of more of the following: the reduction gearbox oil level height indicated by the oil level data is less than or equal to a preset oil level height. The preset oil level height can be set by a system in a self-defined mode, for example, the height of a mailbox of the reduction gearbox is H, and the height of the preset oil level is 1/3H. When the oil level height indicated by the oil level data is less than or equal to 1/3H, indicating that the oil level is insufficient; conversely, when the oil level data indicates an oil level height greater than 1/3H, indicating that the oil level is normal, the next step may be performed.

The reduction gearbox oil temperature indicated by the oil temperature data is greater than or equal to a preset oil temperature. The preset oil temperature can also be set by a system in a self-defining way, such as 60 ℃. When the oil temperature indicated by the oil temperature data exceeds 60 ℃, the oil temperature is indicated to be too high and abnormal; on the contrary, when the oil temperature indicated by the oil temperature data is less than 60 ℃, the oil temperature is normal, and the next step can be carried out.

And the deviation value between the rotating speed of the input shaft and the preset rotating speed is greater than the preset deviation value. The preset deviation value is set by a system in a self-defined mode, for example, the difference is 1%. And when the deviation value between the rotating speed of the input shaft and the preset rotating speed is more than 1%, the equipment connection is not firm, the pendulum shear fault detection system does not allow shearing operation, and the process is ended. Conversely, when the deviation therebetween is less than or equal to 1%, it indicates that the next step can be performed.

The maximum output torque indicated by the power output torque is greater than a preset torque. The preset torque is set by a system in a self-defined mode and can also be called as a system set maximum value. Since the power output torque is obtained by real-time measurement of the torque sensor 19, the value thereof may be plural. When the maximum output torque is larger than the preset torque set by the system, the defect of the equipment is indicated, the pendulum shear fault detection system does not allow shearing operation, and the process is ended. Conversely, when the maximum output torque is less than or equal to the preset torque, the next step can be performed.

The maximum amplitude value indicated by the transmission shaft amplitude is larger than a preset amplitude. The preset amplitude is set by a system user, such as 30 um. In a similar way, because the vibration conditions of different transmission shafts acquired by the transmission shaft amplitude acceleration sensor 4 in real time and the number of the transmission shafts in the system exceeds 1, the maximum amplitude value indicated by the transmission shaft amplitude can be acquired for judgment, specifically, for example, when the maximum amplitude value is greater than 30um (preset amplitude), it indicates that the equipment has a defect, the pendulum shear fault detection system does not allow shearing operation, and the process is ended. Otherwise, when the maximum amplitude value is less than or equal to the preset amplitude, the next step can be carried out.

S403, when the sensing data meet preset fault detection conditions, determining that the pendulum shear equipment corresponding to the pendulum shear fault detection system has a pendulum shear fault.

Optionally, when the pendulum shear equipment corresponding to the pendulum shear fault detection system is judged to have a pendulum shear fault, corresponding pendulum shear fault early warning prompt can be performed. For example, when the oil level is judged to be abnormal, an oil level alarm can be carried out; when the oil temperature is judged to be abnormal, the oil temperature alarm can be carried out; when the rotating speed, the torque or the amplitude are judged to be abnormal, corresponding abnormal alarm can be carried out.

S404, when the sensing data do not meet the preset fault detection condition, determining that the pendulum shear equipment corresponding to the pendulum shear fault detection system does not have a pendulum shear fault.

Optionally, when the pendulum shear equipment corresponding to the pendulum shear fault detection system is judged not to have a pendulum shear fault, the shearing operation of the corresponding steel plate blank to be subjected to pendulum shear can be continuously performed in the system.

Optionally, the process may be ended when a cutting end signal generated by the system is received; if the cutting end signal is not received, the method can jump to the step S401 again to repeatedly detect the pendulum shear fault.

Through implementing this application, possess following several advantages: 1. the whole pendulum shear fault detection system is simple in structure and reliable in control, and manual intervention is not needed in the whole process; 2. the real-time monitoring of the state of the equipment is realized through the real-time monitoring of signals such as oil temperature, oil level, torque, rotating speed, vibration and the like, corresponding fault judgment standards are developed, and the self-determination detection or diagnosis of the pendulum shear fault is realized; 3. by using the embedded data acquisition station, the high-frequency multi-parameter data is rapidly acquired, and the problem of data loss in the conventional detection method is solved; 4. by adopting a wireless network or internet technology, the remote pushing of fault information and equipment information is realized, and the real-time performance of equipment personnel for understanding the operation condition of the pendulum shear is improved.
