Description

Technical Field

[0001] The utility model relates to the technical field of blast furnace coal gun disassembly auxiliary tools, in particular to a tool for safely and quickly disassembling a blast furnace coal gun. Background Art

[0002] The blast furnace is a key piece of equipment in the steelmaking process, used to reduce iron ore into pig iron. During blast furnace operation, coal lances (also known as coal injection lances) inject pulverized coal into the blast furnace, acting as a reducing agent and heat source. Due to the long-term high temperature, high pressure, and corrosive environment, the coal lances require regular inspection, maintenance, and replacement.

[0003] Currently, when replacing a coal injection lance, a pipe clamp is used to remove the lance in-line. Before using the pipe clamp, the jaws are first opened to simulate the lance diameter. This results in an inappropriate opening width during the pipe clamp removal process, requiring readjustment. The heavy weight of the pipe clamp makes it extremely inconvenient to operate and is not suitable for flexible lance removal operations.

[0004] Therefore, there is an urgent need to design a tool for safely and quickly disassembling the blast furnace coal gun to solve the problems of inconvenient operation and being unable to adapt to the gun extraction operation. Utility Model Content

[0005] In view of the problems existing in the prior art, the purpose of the utility model is to provide a tool for safely and quickly disassembling a blast furnace coal gun.

[0006] The technical solution adopted by the utility model to solve its technical problems is: a tool for safely and quickly disassembling a blast furnace coal gun, comprising a handle and a tubular groove for placing the coal gun, wherein the handles are two and the two handles are connected by a rotating connecting shaft, and the tubular groove for placing the coal gun also comprises two pieces, which form a tubular groove when the two pieces of tubular grooves for placing the coal gun are combined.

[0007] Specifically, the handles are two openable and closable handles, and handle covers are provided at the ends of the handles.

[0008] Specifically, the handle cover is arranged at one end of the two handles, and the handle cover is used for anti-slip.

[0009] Specifically, the rotating connecting shaft connects the two handles, and the handles are opened and closed by the rotating connecting shaft.

[0010] Specifically, the coal gun placement tubular groove is a tubular groove when combined, and is two semicircular tubes respectively arranged on the two handles when separated, and an anti-slip pad is provided in the coal gun placement tubular groove.

[0011] Specifically, the anti-slip pad is arranged in the tubular groove where the coal gun is placed.

[0012] The utility model has the following beneficial effects:

[0013] The tool for safely and quickly disassembling the blast furnace coal gun designed by the utility model can effectively improve the disassembly efficiency, reduce the labor intensity of workers, and ensure the safety of operation; the disassembly work of the blast furnace coal gun is completed quickly and safely, which greatly shortens the time of pulling out the coal gun and improves the operation efficiency; at the same time, the tool can also effectively reduce the damage to the equipment caused by improper disassembly, or the burns to the operator caused by the high-temperature coal gun due to improper gun pulling operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 1 It is a schematic diagram of the structure of a tool for safely and quickly disassembling a blast furnace coal gun.

[0015] In the figure: 1-handle, 2-tubular groove for placing the coal gun, 3-rotating connecting shaft, 4-anti-slip pad, 5-handle cover. DETAILED DESCRIPTION

[0016] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely further describe the technical solutions in the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0017] Example 1:

[0018] like Figure 1 As shown, a tool for safely and quickly disassembling a blast furnace coal gun includes a handle 1 and a tubular groove 2 for placing the coal gun. The handles 1 are two and the two handles 1 are connected by a rotating connecting shaft 3. The tubular groove 2 for placing the coal gun also includes two pieces, which form a tubular groove when combined.

[0019] When in use, place the coal gun in the coal gun placement tubular groove 2, which is used to clamp the coal gun. An anti-slip pad 4 is provided in the coal gun placement tubular groove 2. The anti-slip pad 4 is used to increase the friction between the coal gun and the coal gun placement tubular groove 2 to achieve anti-slip. The handle 1 is used to apply force. The handle 1 is provided with a handle cover 5. The handle cover 5 is used to increase the friction between the hand and the handle 1. The handle 1 is connected by a rotating connecting shaft 3. Pull the handle 1 to pull out the coal gun.
