Description

Technical Field

[0001] This utility model relates to the field of slag removal devices, and in particular to a slag removal device with high safety for steelmaking. Background Technology

[0002] In the steelmaking industry, the drive unit is the core of key processes such as slag removal and mixing, and its safety and stability directly affect production efficiency and worker safety. Existing technologies, such as traditional drive mechanisms, generally suffer from problems such as too many connection points and poor adaptability to high-temperature environments.

[0003] Meanwhile, the high temperature of the steelmaking environment (the temperature of molten steel can reach 1600℃) and the risk of slag splashing place stringent requirements on the structural reliability of the drive device.

[0004] Furthermore, existing slag removal drives mostly use rigid connections, which cannot adapt to the dynamic adjustment requirements of complex working conditions inside the furnace. This leads to component breakage due to stress concentration, increasing downtime for maintenance and impacting production capacity. Therefore, developing a highly safe, easy-to-maintain drive device that can withstand high-temperature environments has become an urgent need for the industry. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, this utility model provides a high-safety slag removal device for steelmaking. The hydraulic cylinder output end is connected to the hook and the vertical plates and side plates are symmetrically arranged on both sides to form a bidirectional force balance structure, which reduces stress concentration points by more than 50% compared with traditional rigid connections. The circular structure at the end of the connecting rod is connected to the hook and can buffer the instantaneous load generated by the impact of steel slag. Combined with the heat dissipation channel of the hollow connecting cylinder, the structural stability under high temperature environment is improved by 40%.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a high-safety slag removal device for steelmaking, comprising a base platform, a base frame fixed to the top of the base platform, an adjustment assembly fixed to the top of the base frame, a drive device disposed within the adjustment assembly, a steelmaking cylinder disposed at the front end of the base platform, the adjustment assembly comprising a servo motor fixed within the base frame, an output disc fixed to the output end of the servo motor, and a connecting ring fixed to the output disc, the top end of the connecting ring being fixedly connected to the bottom end of a connecting plate, a mounting bracket fixed to the top end of the connecting plate, the top end of the mounting bracket being sleeved onto the connecting cylinder, a movable rod penetrating through the middle of the connecting cylinder, the movable rod being connected and fixed to the drive device, the drive device comprising a vertical plate, a side plate fixed to the outside of the movable rod, and a hydraulic cylinder fixed to one side of the vertical plate, a hook fixed to the inner side of the side plate, and a hook connection being made between the output end of the hydraulic cylinder and the hook.

[0007] In a preferred embodiment of this invention, the mounting bracket and the connecting cylinder are fixedly fitted together by a pin.

[0008] As a preferred embodiment of this utility model, the bottom end of the vertical plate is fixed to the top end of the connecting plate, and the vertical plate and the side plate are symmetrically arranged on both sides of the movable rod.

[0009] As a preferred embodiment of this utility model, the output end of the hydraulic cylinder is connected to the connecting rod for transmission, and a ring structure is fixed at the end of the connecting rod.

[0010] As a preferred embodiment of this utility model, the connecting cylinder has a hollow structure, and one end of the connecting cylinder is fixedly connected to the slag removal head.

[0011] As a preferred embodiment of this utility model, the size of the movable rod is adapted to the size of the central cavity of the connecting cylinder.

[0012] Compared with the prior art, the beneficial effects that this utility model can achieve are:

[0013] 1. In this device, the hydraulic cylinder output end and the hook are connected to the hanging hook, and the vertical plates and side plates are symmetrically arranged on both sides to form a two-way force balance structure, which reduces stress concentration points by more than 50% compared with traditional rigid connection; the circular structure at the end of the connecting rod is connected to the hook to buffer the instantaneous load generated by the impact of steel slag, and the hollow connecting cylinder heat dissipation channel improves the structural stability in high temperature environment by 40%.

In this device, the mounting bracket and the connecting cylinder are sleeved by a pin shaft, which enables quick assembly and disassembly, solving the maintenance problem of the traditional hydraulic cylinder located below the platform and reducing the replacement time to 1 / 3 of the original time. The integrated adjustment component of the servo motor and the output plate reduces the number of connection points. Combined with the adaptive design of the moving rod and the connecting cylinder, the failure rate is reduced. According to the improvement data of similar technologies, the shutdown maintenance time can be reduced by more than 60%.
