Abstract
Description
Technical Field
[0001] This utility model relates to the field of metallurgical production equipment, and in particular to a blast furnace cleaning rod connecting device. Background Technology
[0002] In the metallurgical production and processing process, blast furnaces are often used to smelt metals. After long-term use, burrs will gradually accumulate inside the blast furnace. If the burrs are not cleaned in time, it will easily affect the normal use of the blast furnace.
[0003] Currently, blast furnace tinder removal involves inserting an excavator into the furnace through the maintenance manhole cover. However, the varying distances between the manhole cover and different areas of the tinder buildup within the furnace wall prevent the normal impact head from effectively removing it. Therefore, a tamping rod needs to be welded to the front of the impact head. Traditionally, to ensure the weld's strength, extensive welding is required at the connection point between the tamping rod and the impact head. This results in longer removal times and makes tamping rod replacement inconvenient. Furthermore, traditional tamping rods are typically single pieces, meaning that when the front end wears down and needs replacement, the entire rod must be replaced, leading to significant waste and increased production costs. Therefore, improvements are needed. Utility Model Content
[0004] To address the aforementioned problems, this utility model provides a blast furnace tampering rod connecting device, comprising a connecting sleeve, an installation column at the lower end of the connecting sleeve, and a tamping rod below the connecting sleeve. The tamping rod includes a first connecting section and a second connecting section. An installation groove is provided at the upper end of the first connecting section, and the installation column is installed in the installation groove. Both the first connecting section and the installation column have through holes, and the two through holes coincide when the first connecting section and the installation column are connected. A first pin is inserted at the position of the through hole, and a nut is installed on the first pin and fixed by the nut. An insertion groove is provided at the lower end of the first connecting section, and the second connecting section is located below the first connecting section. An insertion protrusion is provided at the upper end of the second connecting section, and the insertion protrusion is inserted into the insertion groove to connect the second connecting section and the first connecting section.
[0005] Preferably, an impact head is welded to the upper end of the connecting sleeve.
[0006] Preferably, the mounting post is provided with external threads.
[0007] Preferably, the upper end of the first connecting segment is provided with a mounting groove, and the mounting groove is provided with an internal thread.
[0008] Preferably, multiple reinforcing ribs are welded onto the first connecting segment.
[0009] Preferably, both the insertion slot and the insertion protrusion are provided with through holes, and the two through holes overlap after the first connecting section and the second connecting section are inserted. A second pin is inserted through the through hole, and a nut is provided on the second pin and fixed by the nut.
[0010] The beneficial effects of this utility model are: the structure of this utility model is reasonable and easy to use. Through the multi-segment assembly connection, the tamping rod can be installed quickly and easily, and the tamping rod can also be replaced locally, saving production costs.

[0018] like Figure 1 , 2A blast furnace tamper tamping rod connecting device shown in Figure 3 includes a connecting sleeve 2. A mounting post 4 is provided at the front end of the connecting sleeve 2. A tamping rod 1 is provided below the connecting sleeve 2. The tamping rod 1 includes a first connecting section 5 and a second connecting section 8. A mounting groove 6 is provided at the upper end of the first connecting section 5. The mounting post 4 is installed in the mounting groove 6. Both the first connecting section 5 and the mounting post 4 have through holes, and the two through holes coincide when the first connecting section 5 and the mounting post 4 are connected. A first pin 7 passes through the through hole. A nut is installed on the first pin 7 and fixed by the nut. A insertion groove 9 is provided at the lower end of the first connecting section 5. The second connecting section 8 is located below the first connecting section 5. An insertion protrusion 10 is provided at the upper end of the second connecting section 8. The insertion protrusion 10 is inserted into the insertion groove 9 to connect the second connecting section 8 with the first connecting section 5.
