All-round metal smelting slag salvaging robot

Abstract

The invention discloses an all-round metal smelting slag salvaging robot, which is suitable for clearing waste slag in the smelting process of steel, iron, copper, aluminum and various nonferrous metals. The slag salvaging robot comprises a grabbing mechanism, wherein the grabbing mechanism is connected to a four-connecting-rod mechanism, the four-connecting-rod mechanism comprises a large arm, the lower end of the large arm is hinged to a rotary disc, and is connected with a second servo motor through a slewing bearing, the upper end of the large arm is hinged to a small arm, the front end ofthe small arm is connected with the grabbing mechanism through a connecting arm, the rear end of the small arm is hinged to the upper end of a pull rod, and the pull rod is fixed on the rotary disc.According to the robot, the flexibility of the robot can be improved, dross can be grabbed in all directions, dross salvaging dead corners are avoided, the operation stability of the robot can be improved, the phenomena of shaking and vibration in the operation process of the robot are effectively reduced, the grabbing accuracy is improved, and molten iron splashing and robot pollution caused by dross falling due to shaking and vibration are avoided.

Description

technical field [0001] The invention relates to an all-round metal smelting slag removal robot, which belongs to the technical field of metal smelting equipment. Background technique [0002] As we all know, a large amount of scum will be generated during the metal smelting process, which will float on the inner surface of the smelting furnace or adhere to the inner wall of the furnace. If the scum is not cleaned, it will affect the quality of molten iron and castings. However, manual slag removal requires the slag remover to wear thick protective tools and use a long iron fork to pick slag outside the furnace. This method is not only dirty when picking slag many times, but also it is not safe to splash molten iron during the process. The temperature in the furnace can reach 1,500 degrees Celsius, especially in summer, around the furnace mouth can reach hundreds of degrees Celsius, the working environment is very harsh, and it is also dangerous. Moreover, the scum has a cer...

AI Technical Summary

Problems solved by technology

[0005] 1. During the slag removal operation, the existing slag removal equipment has poor flexibility. The slag removal gripper cannot grasp the scum in the smelting furnace in all directions. Dead corners require manual cleaning, which is time-consuming, labor-intensive, and poses a greater safety risk

[0006] 2. The slag removal equipment generally includes slag removal, slag transportation and slag discharge. During the operation of the existing slag removal equipment, the operating mechanism of the existing slag removal equipment shakes and vibrates relatively violently, and the operation stability is poor. The vibration and shaking of the mechanism are prone to inaccurate grasping; on the other hand, the dross grasped by the gripper is easy to fall into the melting furnace due to the vibration and shaking of the mechanism, causing molten iron to splash, which not only causes waste of molten iron, There is also a greater security risk

During the process of slag transportation, the scum caught by the gripper will fall due to the vibration and shaking of the mechanism and pollute the production equipment and production site, which will bring difficulties to the later cleaning

[0007] In summary, there are obviously inconveniences and defects in the actual use of the existing technology, so it is necessary to improve
