Description

Technical Field

[0001] The utility model relates to the technical field of automatic sampling equipment for ironmaking raw materials in the metallurgical industry, in particular to an auxiliary installation tool for a blast furnace tuyere sleeve. Background Art

[0002] As the air supply device of the blast furnace, the tuyere sleeve works in a very harsh environment. It not only has to withstand the high-speed scouring of high-temperature hot air, the erosion of liquid slag iron, and the impact of high-temperature coke, but also the coal powder sprayed from the coal gun may cause wear and tear. In such a harsh working environment, the tuyere sleeve is very easy to burn out and often needs to be replaced. The installation process of the tuyere sleeve is as follows: after the tuyere sleeve is hoisted to the tuyere of the blast furnace, a striker is used to hit the tuyere sleeve so that the tuyere sleeve is embedded in the tuyere of the blast furnace. When using the striker to hit the tuyere sleeve, the manual method is mainly used, that is, manually lifting and moving the striker to hit the tuyere sleeve.

[0003] In the process of manually lifting and moving the striker, in order to save effort, the existing practice is to erect a bracket as a fulcrum, and after the striker is placed on the bracket, manually adjust the impact angle of the striker at the end of the striker, and push and pull the striker to impact the air inlet sleeve. The impact rod impacts the air outlet sleeve, and the impact parts include the upper part, middle part, lower part and other parts of the air outlet sleeve. Under the existing impact method, due to the height limitation of the operator, the adjustable impact angle of the impact rod is limited. For this reason, not all positions of the air outlet sleeve can be impacted with the aid of the bracket. In other words, the impact range that can be impacted with the aid of the bracket is small and cannot cover all parts of the upper part, middle part and lower part of the air outlet sleeve. For the parts that are not covered by the air outlet sleeve, it is still necessary to manually lift the impact rod to impact. If the impact range that can be impacted with the aid of the bracket covers the upper and middle parts of the air outlet sleeve, but does not cover the lower part of the air outlet sleeve, then when impacting the lower part of the air outlet sleeve, it is impossible to use the bracket, but can only rely on manually lifting the impact rod to impact. This impact method is still more laborious, and the convenience of operation needs to be further improved. Moreover, even if part of the position of the covering air inlet sleeve can be hit with the help of the bracket, when the push-pull frame is placed on the impact rod of the bracket, there is sliding friction between the impact rod and the bracket, and the friction force is relatively large. It is laborious to move the impact rod manually, and the labor intensity is high. The operation is still time-consuming and labor-intensive, and the installation efficiency needs to be further improved. Utility Model Content

[0004] The utility model aims to provide an auxiliary installation tool for a blast furnace tuyere sleeve.

[0005] The technical solution for achieving the purpose of the utility model is: an auxiliary installation tool for a blast furnace tuyere sleeve, used for setting up a striker rod for striking the tuyere sleeve to install the tuyere sleeve, comprising a bracket, on which a first roller and a second roller are rotatably mounted, the first roller and the second roller are parallel and arranged with an interval up and down, the spacing between the first roller and the second roller is greater than the maximum diameter of the striker rod, the first roller is located above the second roller, the position height of the first roller is limited to the striker rod frame being placed on the first roller to strike the upper part of the tuyere sleeve, and the position height of the second roller is limited to the striker rod frame being placed on the second roller to strike the lower part of the tuyere sleeve.

[0006] Furthermore, the bracket includes a left bracket and a right bracket connected to each other, and the two end rollers of the first roller and the second roller are installed on the left bracket and the right bracket, and the first roller is located on the top of the left bracket and the right bracket. After the first roller is located on the top of the left bracket and the right bracket, there is no obstacle above the first roller, and the space above the first roller is more open, which is convenient for the impact rod frame to be placed on the first roller for impact operation. At the same time, the impact angle that can be adjusted by the impact rod frame on the first roller is also larger, which is more conducive to operation.

[0007] The utility model provides an auxiliary installation tool for a blast furnace tuyere sleeve, wherein the first roller and the second roller arranged on the bracket can not only serve as brackets for the striker rod to provide supporting force for the striker rod; and after the striker rod is supported on the first roller or the second roller, in addition to manually holding the end of the striker rod and slightly adjusting the impact angle of the striker rod, when the first roller and the second roller are arranged in an upper and lower interval arrangement and the impact height of the striker rod supported on the first roller is different from the impact height of the striker rod supported on the second roller, the striker rod can also be mounted on the first roller or the second roller, and the impact height of the striker rod can be greatly adjusted by selecting and using one of the first roller and the second roller for replacement, and the impact height of the striker rod is greatly adjusted, and the impact range of the striker rod is not only large, but also the combination of small adjustment and large adjustment makes the adjustment of the impact position of the striker rod more flexible. In addition, the rotatable installation of the first roller and the second roller enables rolling friction between the impact rod and the first roller, or between the impact rod and the second roller when the impact rod is placed thereon and pushed and pulled to impact, resulting in small friction and more labor-saving push and pull operations.

[0008] With the support of the auxiliary installation tool of the blast furnace tuyere sleeve of the utility model, the impact range of the impact rod is not only large, but also the entire tuyere sleeve including the upper part and the lower part can be impacted, and the impact position of the impact rod can be flexibly adjusted, and the flexibility of the installation operation can be higher. At the same time, the push-pull friction force of the impact rod is also small, and the entire installation operation saves time and labor, and the installation operation can be more convenient and the installation efficiency is higher.
