Embodiment 1

[0044] like Figure 1 to Figure 5 As shown, a ladle hydraulic tilting angle monitoring device in this embodiment includes a base 1 , a movable support 2 , an oil cylinder 3 and a rotation angle measuring mechanism 4 . Wherein, the base 1 has a column 101, the upper end of the movable support 2 and the column 101 is hingedly connected by a pin; one end of the oil cylinder 3 is hingedly connected with the base 1, and the other end is hingedly connected with the movable support 2.

[0045] When using the above-mentioned device to complete the ladle overturning process, the overturning angle of the ladle is a very important index. Through it, information such as the position of the ladle, the dumping status of the molten steel, and the stable operation of the equipment can be known. It is important for the stability of the equipment operation, Reliability and security are paramount. However, the measurement of the tipping angle of the ladle is very difficult, and several problems...

Embodiment 2

[0055] A ladle hydraulic flip angle monitoring device of this embodiment is basically the same as Embodiment 1, the difference is that: the device is provided with a position sensing device 5; figure 1 , image 3 , Image 6 and Figure 7 , the position sensing device 5 is provided with two, one is used to detect whether the movable support 2 is in the initial state position, and the other is used to detect whether the movable support 2 is in the position of the maximum tipping state, so that the operating state of the movable support 2 can be understood , it is convenient for the control system to control the action of the oil cylinder 3, and the time for pouring the molten steel from the ladle can be controlled through the control system to meet the requirements of intelligent control. Specifically, the position sensing device 5 includes a sensing trigger component 510 and a sensing receiving component 520. The sensing triggering component 510 includes a sensing touch panel...

Embodiment 3

[0058] A ladle hydraulic flip angle monitoring device of this embodiment is basically the same as Embodiment 2, except that the induction receiving component 520 includes a protection box 522, a rectangular tube 523 and a splint 524 in addition to the induction switch 521 , combined with figure 1 , image 3 , Image 6 , Figure 7 and Figure 8 , the rectangular tube 523 is set on the base 1 or the column 101 of the base 1, the protective box 522 is installed on the rectangular tube 523, the induction switch 521 is arranged in the protection box 522, and the induction switch 521 is protected to avoid damage; the rectangular tube 523 is provided with an adjustment slot along the length direction, and the protection box 522 is connected with the splint 524 arranged in the rectangular tube 523 through the adjustment slot of the rectangular tube 523 through bolts. In this structure, the installation position of the protection box 522 on the rectangular tube 523 Adjustable, it i...

Abstract

The invention discloses a device and a method for monitoring the hydraulic turnover angle of a molten steel ladle, and belongs to the technical field of metallurgy. In the device, a movable support is connected with the stand column of a base through a pin shaft. A turnover angle measurement mechanism comprises an upper angle gearbox and a lower angle gearbox. The movable support is provided with a large gear overlapped with the axis of the pin shaft. A pinion is mounted on the input shaft of the upper angle gearbox. The large gear and pinion are in engagement transmission with each other. The output shaft of the upper angle gearbox and the input shaft of the lower angle gearbox are connected through a universal coupling. The output shaft of the lower angle gearbox is connected with an encoder through an elastic coupling. According to the method, the angular displacement of the movable support is obtained through the turnover angle measurement mechanism. Meanwhile, the angular displacement is converted into an electric signal and the electric signal is sent to a control system. Therefore, the turnover angle of the molten steel ladle is monitored in real time. Based on the device and the method, the real-time monitoring of the turnover angle of the molten steel ladle in high-temperature, high-vibration, high-pollution and other severe environments is realized. Meanwhile, the stability, the reliability and the safety of equipment operation can be ensured.

Description

technical field [0001] The invention belongs to the technical field of metallurgical equipment, and more specifically relates to a ladle hydraulic flip angle monitoring device and a method thereof. Background technique [0002] At present, the steelmaking workshops of most iron and steel plants in the domestic and foreign metallurgical industry, especially the steelmaking production lines of the continuous casting process, need to be equipped with ladle hot repair devices - ladle turning devices. At present, the commonly used ladle overturning methods include: hoisting overturning, driving overturning, mechanical overturning, hydraulic overturning, etc., each with its own advantages and disadvantages. The investment in hoisting and tipping equipment is relatively small, but the investment in civil engineering is relatively large, and the investment in equipment maintenance is relatively large. The input cost is very high, and the track occupancy rate of the train is high, w...
