Description

Technical Field

[0001] The utility model belongs to the technical field of taphole opening machines, and in particular relates to a large-angle rotary taphole opening machine. Background Art

[0002] The hydraulic taphole opening machine is one of the key equipment in front of the blast furnace. Its function is to open the taphole at a certain angle to ensure that the molten iron flows out smoothly from the channel. At present, the taphole opening machines used in most large and medium-sized blast furnaces on the market are KJT / X taphole opening machines. This type of taphole opening machine is generally a four-bar mechanism, and the rotation is driven by a hydraulic cylinder. The rotation angle is less than 115°, and the running track cannot be adjusted during the rotation process.

[0003] Moreover, the entire rotating mechanism of the KJT / X-type iron mouth opening machine is bolted to the base seat, and the base seat is installed on the plane of the iron-making yard in front of the furnace through anchor bolts. Before installation, the foundation of the iron-making yard needs to be aligned and the anchor bolts need to be grouted once; when the base seat is installed, it is necessary to measure and align it again, and perform secondary grouting, and the foundation installation is cumbersome; and the rotating mechanism of the KJT / X-type iron mouth opening machine is a four-bar mechanism with a small rotation angle; it does not contain a control connecting rod, and the trajectory cannot be adjusted during the rotation process, and it occupies a large area, and it is easy to interfere with the hydraulic mud gun and columns in front of the furnace; the KJT / X-type iron mouth opening machine also has problems such as most pipelines are connected by hoses, there are many types of hoses, which are easy to damage, users need to prepare more spare parts, and the cost is high.

[0004] Therefore, it is urgent to design a large-angle rotary taphole opening machine to solve the problems existing in the existing taphole opening machines.

[0005] In view of this, the present utility model is proposed. Utility Model Content
