Description

Technical Field

[0001] The utility model relates to the technical field of tuyere of an ironmaking blast furnace, in particular to an installation tool for a tuyere blowpipe of a blast furnace. Background Art

[0002] As the blast furnace's air supply device, the tuyere blowpipe operates in an extremely harsh environment. In addition to enduring the high-speed blast of hot air, the erosion of liquid slag, the impact of hot coke, and the abrasion of pulverized coal ejected from the lance, if the corresponding fan fails, the tuyere blowpipe cannot generate positive pressure toward the blast furnace, which can easily cause slag to fill the tuyere blowpipe. These factors necessitate frequent replacement of the tuyere blowpipe. The tuyere blowpipe consists of a straight blowpipe at the front and an elbow at the rear. The straight blowpipe's diameter gradually decreases from front to back, and the addition of the elbow makes the tuyere blowpipe lighter at the front and heavier at the back, weighing approximately one ton overall. Traditionally, the tuyere blowpipe is supported by two clevises. During installation, a forklift is used to lift the tuyere blowpipe directly from the bottom of the clevis, transporting it to the installation location. The diameter of the blowpipe gradually decreases from front to back. To ensure the lifted blowpipe is horizontal and aligned with the tuyere sleeve and upper nipple for easy installation, a custom-built forklift is required, resulting in high costs. Furthermore, due to the unsuitability and limitations of conventional forklifts, ease of use is also limited. Furthermore, after the forklift lifts the blowpipe, temporary placement requires the pipe to be dropped to the ground, which can easily damage the tuyere platform. Utility Model Content

[0003] The utility model aims to provide a tool for installing a blast furnace tuyere blowpipe.

[0004] The technical solution for achieving the purpose of the utility model is: a tool for installing a blast furnace tuyere blowpipe, comprising a bracket, a front crossbeam and a rear crossbeam, the number of the brackets being two, the two brackets being arranged at intervals, each of the brackets comprising a stand and a channel steel, the stand being upright, the channel steel being located above the stand and being fixed to the stand, the channel steel having a horizontal through hole, the horizontal through holes of the channel steels in the two brackets being parallel; the front crossbeam being arranged horizontally between the two brackets, the two ends of the front crossbeam being fixed one-to-one with the two channel steels The top of the front crossbeam is higher than the horizontal through hole; the rear crossbeam is horizontally arranged between the two brackets, and the two ends of the rear crossbeam are fixed to the two brackets one by one, the rear crossbeam and the front crossbeam are arranged at intervals, and the rear crossbeam has an upward arc-shaped positioning opening, and the two ends of the arc-shaped positioning opening extend toward the two brackets respectively, and the bottom of the arc-shaped positioning opening is lower than the horizontal through hole, and the height difference between the bottom of the arc-shaped positioning opening and the top of the front crossbeam is limited to the horizontal state after the air outlet blowpipe is placed on the front crossbeam and the rear crossbeam.

[0005] Furthermore, the two brackets are arranged in parallel. The parallel arrangement is more regular and neater.

[0006] Furthermore, the vertical bracket is of a frame structure. The vertical bracket of the frame structure is lighter.

[0007] Furthermore, the channel steel is arranged longitudinally.

[0008] Furthermore, the cross-section of the horizontal through-hole is a flat rectangle. The horizontal through-hole of the flat rectangle fits better with the shape of the forklift fork, facilitating the insertion of the forklift fork into the horizontal through-hole and matching with the horizontal through-hole.

[0009] Furthermore, the front crossbeam is located above the channel steel and fixed to the channel steel. The front crossbeam can be fixed to the vertical bracket or fixed to the channel steel. When the front crossbeam is located above the channel steel and fixed to the channel steel, the firmness of the fixing structure is stronger and the load-bearing capacity of the front crossbeam is greater.

[0010] Furthermore, the rear crossbeam is located below the channel steel. The side surface of the rear crossbeam is fixed to the vertical bracket, and the top of the rear crossbeam is fixed to the channel steel. The rear crossbeam is fixed to both the vertical bracket and the channel steel, and the overall structure has better firmness.

[0011] Furthermore, the horizontal height of the bottom of the rear crossbeam is consistent with the horizontal height of the bottom of the vertical bracket. In this setting, when the vertical bracket stands on the ground, the rear crossbeam also stands on the ground. The rear crossbeam standing on the ground can also be used for support, sharing the force for the vertical bracket and making the support structure stronger.

[0012] For the installation tool of the blast furnace tuyere blowpipe of the present utility model, by horizontally fixing the front crossbeam and the rear crossbeam between the two brackets, and at the same time making the horizontal height of the bottom of the arc-shaped positioning port lower than the horizontal height of the top of the front crossbeam, after the straight blowpipe of the tuyere blowpipe is placed on the front crossbeam and the rear crossbeam, it can not only be supported by the front crossbeam and the rear crossbeam together, but also considering the structural feature that the diameter of the straight blowpipe gradually decreases from front to back, the front section with a smaller diameter of the straight blowpipe is placed on the front crossbeam at a higher position, and the rear section with a larger diameter of the straight blowpipe is placed on the rear crossbeam at a lower position. The height difference between the front crossbeam and the rear crossbeam can also perform height compensation for the diameter difference of the straight blowpipe that gradually decreases in diameter from front to back. Through this height compensation, finally, the straight blowpipe with a diameter gradually decreasing from front to back can be placed in a horizontal state.

[0013] After the tuyere blowpipe is placed horizontally on the installation tool for the blast furnace tuyere blowpipe of the present utility model, in addition to better stability during placement, it also combines the setting of the channel steel and the horizontal through holes thereon. When installing the tuyere blowpipe, the forklift forks can be directly inserted into the horizontal through holes, and the installation tool for the blast furnace tuyere blowpipe and the tuyere blowpipe placed thereon can be lifted horizontally for installation. When the forklift forks are directly inserted into the horizontal through holes and the installation tool for the blast furnace tuyere blowpipe and the tuyere blowpipe placed thereon are lifted horizontally for installation, on the one hand, the tuyere blowpipe is already in a horizontal state, and it does not require a specially customized forklift. An ordinary forklift can be used for operation. The application of the forklift is not restricted, and the use cost is low and the convenience is high. On the other hand, during the process of lifting and installing together with the installation tool for the blast furnace tuyere blowpipe, whenever it is necessary to put down the tuyere blowpipe, the installation tool for the blast furnace tuyere blowpipe can be put down together. The tuyere blowpipe can always be placed on the installation tool for the blast furnace tuyere blowpipe and will not be directly placed on the ground, so as not to damage the tuyere platform ground.

[0014] In addition, for the installation tool for the blast furnace tuyere blowpipe of the present utility model, the top of the front crossbeam is higher than the horizontal through hole, the bottom of the arc-shaped positioning port is lower than the horizontal through hole, and the horizontal through hole is located between the arc-shaped positioning ports of the front crossbeam and the rear crossbeam. After the straight blowpipe of the tuyere blowpipe is placed on the front crossbeam and the rear crossbeam, when the forklift forks are directly inserted into the horizontal through holes and the installation tool for the blast furnace tuyere blowpipe and the tuyere blowpipe placed thereon are lifted, the forklift forks are closer to the center of the tuyere blowpipe, and the center of gravity of the tuyere blowpipe is lower relative to the forklift forks. During the process of lifting the tuyere blowpipe, the tuyere blowpipe with a lower center of gravity relative to the forks has better running stability, greatly reducing the risk of the tuyere blowpipe shaking and falling during the handling process.
