AI Technical Summary

Technical Problem

The weight of the existing blast furnace chute replacement tooling is small, which makes it difficult to remove the chute and cannot meet the weight required for chute removal.

Method used

A special tool for replacing blast furnace chutes is designed, including support rods, counterweights, connecting rods and reinforcement rods. By adjusting the angle between the connecting rods and the supporting rods to 150°, the lever principle is used to increase the force of disassemblying the chutes.

Benefits of technology

It realizes that the chute can be disassembled directly without external force, saves manpower and material resources, reduces the demand for new equipment and reduces the filing costs.

Description

Technical Field

[0001] The utility model belongs to the technical field of blast furnace chute replacement, and in particular relates to a special tool for replacing a blast furnace chute. Background Art

[0002] The existing blast furnace chute replacement tooling is 2500cm long, with a 45-degree curved opening size of 1070*980cm at the front end and a counterweight of 1.5 tons. The existing tooling has a small counterweight. Each time the chute is replaced, a lifting nose must be welded at the rear end of the tooling and a hand winch must be used to increase the counterweight and remove the chute.

[0003] The rear end of the tooling is a 180-degree parallel beam without any bends, and the counterweight cannot play its original counterweight role, making it difficult to remove the chute. The total length of the tooling is short, and according to the principle of leverage, the weight required for removing the chute cannot be reached (i.e., the tooling weight is less than the mass of the chute itself).

[0004] Therefore, a special tool for replacing a blast furnace chute is needed. Utility Model Content

[0005] The utility model aims to provide a special tool for replacing a blast furnace chute.

[0006] The technical solution adopted by the utility model to solve its technical problems is: a special tooling for replacing a blast furnace chute, comprising a support rod, a counterweight is installed at the first end of the support rod, a connecting rod is installed on the second end of the support rod, the angle between the connecting rod and the support rod is 150°, and an opening is provided at the end of the connecting rod.

[0007] Specifically, a reinforcement rod is provided on the connecting rod.

[0008] Specifically, the number of the support rods is 2 and they are installed on both sides of the counterweight.

[0009] Specifically, the number of the reinforcement rods is 2 and they are installed between the connecting rods.

[0010] The utility model has the following beneficial effects:

[0011] 1) After using the utility model, the chute can be directly disassembled without the help of other external forces, saving manpower and material resources;

[0012] 2) Changing the tooling crossbeam from 180 degrees to 150 degrees does not require additional counterweights, saving the cost of submitting new tooling parts. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 1 It is a structural schematic diagram of the utility model.

[0014] In the figure: 1-support rod; 2-counterweight; 3-connecting rod; 4-angle; 5-opening; 6-reinforcement rod. DETAILED DESCRIPTION

[0015] The utility model will now be further described in detail with reference to the accompanying drawings.

[0016] like Figure 1 As shown, a special tool for replacing a blast furnace chute includes a support rod 1, a counterweight 2 is installed on the first end of the support rod 1, a connecting rod 3 is installed on the second end of the support rod 1, the angle between the connecting rod 3 and the support rod 1 is 150°, and an opening 5 is provided at the end of the connecting rod 3.

[0017] A reinforcing rod 6 is provided on the connecting rod 3 , the number of the supporting rods 1 is two and they are installed on both sides of the counterweight 2 , and the number of the reinforcing rods 6 is two and they are installed between the connecting rods 3 .

[0018] The method of using the utility model is as follows: the opening 5 is connected to the end of the chute, and after the counterweight 2 is pressed down, since the angle between the connecting rod 3 and the supporting rod 1 is 150°, the counterweight is used to lift the chute by levering the original position, and at this time the chute is taken out from the opening of the side wall of the blast furnace, thereby improving the convenience of replacing the chute.

[0019] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0020] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
