However, such traditional methods are time-consuming and laborious, and there is a high safety risk. SUMMARY

[0040] The starting device 10 is fixed at the edge of the steel plate 6, and comprises a transmission track controller and a power supply for the transmission track controller.

[0041] The transmission track controller is used for controlling the starting, stopping, transmission speed and transmission direction of the transmission structure 8.

[0042] Embodiment 2:

[0043] The main structure of the embodiment is the same as that of embodiment 1, and further, the transmission structure 8 comprises a track 801, a rotating shaft 802, a chain 804 and a gear 805.

[0044] The rotating shafts 802 are arranged along the axis direction of the secondary beam 7.

[0045] The outer side of the rotating shafts 802 is surrounded by the track 801.

[0046] One side end surface of the rotating shafts 802 faces the secondary beam 7, and the other side end surface is fixed with the gear 805. The outer side of the gears 805 is surrounded by the chain 804, and the chain 804 is engaged with the gear teeth of each gear 805.

[0047] Embodiment 3:

[0048] The main structure of the embodiment is the same as that of embodiment 2, and further, the outermost two rotating shafts 802 are integrated with a direct-current driving motor, the output shaft of the direct-current driving motor is connected with the rotating shaft 802 through a shaft coupling, for driving the outermost two rotating shafts 802 to rotate, and based on the outermost two rotating shafts 802, the gears 805 fixed thereon are driven to rotate, then through the chain 804 engaged with the gears 805, all the gears 805 are driven to rotate, and all the gears 805 rotate at the same time and further drive all the rotating shafts 802 to rotate, so as to realize the movement of the track 801.

[0051] The motor driver is built-in with a current sensor for real-time monitoring of the armature current of the DC driving motor, and a current change rate threshold or a current threshold is set in the motor driver, so that when the current changes too fast or exceeds the threshold, the system determines that the load is too large or an abnormal situation occurs, and the alarm 11 is started to alarm. The alarm 11 is electrically connected with the motor driver.

[0052] Among them, the judgment basis of the current changing too fast is that when the current rising rate exceeds 300A / s, it is judged that the conveying belt appears to be stuck, the alarm is triggered, and the machine is stopped within 500 milliseconds.

[0053] Exceeding the threshold: The general judgment standard is mainly that the absolute value of the current exceeds a certain percentage of the rated value and lasts for a period of time. The early warning value is 110% to 115% of the rated current, and the shutdown value is 125% to 150% of the rated current.

[0054] The current sensor generally uses a Hall effect current sensor (such as Allegro ACS712, ACS758, and domestic CH704), and the sensor has a magnetic core inside, and the current lead passes through the magnetic core or is close to the Hall element. The magnetic field generated by the current in the lead is detected by the Hall element and outputs a voltage signal proportional to the current.
