Description

Technical Field:

[0001] The utility model relates to the technical field of steelmaking equipment, in particular to a drill rod bracket for a borer of a blast furnace taphole machine. Background Art:

[0002] The blast furnace taphole machine equipment is a general equipment for opening the iron notch in domestic blast furnace smelting at present, and is used for opening the iron notch and penetrating the iron notch during the production process. Due to frequent use, the drill rod bracket vibrates due to impact during use, and the bracket is close to the iron notch. High temperature and the splash and scouring of molten iron during tapping often cause the bracket to fall off and be damaged, and the replacement frequency is extremely high. Since the fixing method is bolt plus welding, after the bracket is damaged, it is necessary to use gas cutting to cut off the damaged bracket, replace it with a new bracket, fix it with bolts and then weld it. There are also environmental factors. Since the taphole machine is in a high-temperature environment, when replacing the bracket, the harm caused by high temperature to maintenance personnel is very great, and they are often scalded or burned by the splashing molten iron. Content of the Utility Model:

[0003] The purpose of the utility model is to overcome the deficiencies of the above-mentioned existing technologies, and provide a drill rod bracket for a borer of a blast furnace taphole machine, which improves safety and reduces the labor intensity of workers.

[0004] In order to solve the problems in the background art, the utility model adopts the following technical scheme: it includes a blast furnace taphole machine body, a robotic arm, a drill rod and a drill rod bracket. One end of the blast furnace taphole machine body is connected to one end of the robotic arm, and the other end of the robotic arm is connected to a fixing device. The drill rod bracket is welded on the fixing device, and the drill rod is placed on the drill rod bracket.

[0005] One side of the fixing device is connected to the robotic arm, and a suspension groove is opened on the other side of the fixing device.

[0006] The upper part of the drill rod bracket is L-shaped, and the lower part is J-shaped.

[0007] The upper L-shaped part of the drill rod bracket passes through the suspension groove and is fixedly connected to the suspension groove.

[0008] The end of the drill rod is placed inside the lower J-shaped part of the drill rod bracket.

[0009] The beneficial effect of the utility model is: in order to avoid scalding or burning caused by high temperature and the splash of molten iron, it is necessary to improve the convenience and practicability of replacing the bracket. In order to stabilize the operation of the equipment, it is necessary to improve the working efficiency of replacing the bracket and reduce the labor intensity of workers. Description of the Drawings:

[0011] Figure 2This is a diagram showing the connection relationship between the fixing device and the drill rod bracket of the utility model;

[0012] Figure 3 It is a schematic diagram of the structure of the fixing device of the utility model;

[0013] Figure 4 It is a structural schematic diagram of a drill rod bracket of the utility model. Specific implementation method:

[0014] With reference to the figures, the utility model specifically adopts the following implementation mode: it includes a blast furnace opening machine body 1, a mechanical arm 2, a drill rod 4 and a drill rod bracket 3, one end of the blast furnace opening machine body 1 is connected to one end of the mechanical arm 2, the other end of the mechanical arm 2 is connected to a fixing device 5, the drill rod bracket 3 is welded on the fixing device 5, and the drill rod 4 is placed on the drill rod bracket 3. One side of the fixing device 5 is connected to the mechanical arm 2, and the other side of the fixing device 5 is provided with a hanging groove 6. The upper part of the drill rod bracket 3 is L-shaped, and the lower part is J-shaped. The upper L-shaped part of the drill rod bracket 3 passes through the hanging groove 6 and is fixedly connected to the hanging groove 6. The end of the drill rod 4 is placed in the J-shaped part of the lower part of the drill rod bracket 3.

[0015] The tapping machine is used to open the tapping hole when tapping iron in a blast furnace. It is a medium-sized hydraulic hole-turning equipment. The working principle is to use the hydraulic system to propel the rock drill to rotate and impact and drive the 3.2-meter drill rod to turn the tapping hole. Since the drill rod 4 is relatively long, the original manufacturer designed to add a fixed bracket to the front section of the tapping machine to stabilize the drill rod. The bracket is fixed in two ways: bolts and welding. During use, the impact causes vibration and the bracket is close to the tapping hole. The high temperature and the splashing of molten iron during tapping often cause the bracket to fall and be damaged. The replacement frequency is very high. The disassembly and installation of the bracket fixed by welding and bolts is time-consuming and laborious, and it is difficult to replace it in a high-temperature environment during tapping iron. By improving the fixing method of the drill rod bracket 3, the bracket can be replaced quickly and conveniently, thereby improving work efficiency.

[0016] When the drill rod bracket of the blast furnace opening machine rock drill is in use, the self-made fixing device 5 is welded and fixed to the mechanical arm 2 at one time, and the self-made drill rod bracket 3 is fixed to the hanging groove 6 in a hanging manner, which is convenient and firm to use and not easy to fall off, and is easy to replace.

[0017] This blast furnace opening machine rock drill has improved bracket fixing method, which is more suitable for on-site application, improves maintenance work efficiency, reduces labor intensity of employees, and reduces the harm caused by long-term work of staff in high temperature environment.

[0018] In summary, in order to avoid scalding or burns caused by high temperature and molten iron splashing, the convenience and practicality of replacing the bracket must be improved. In order to stabilize the operation of the equipment, the work efficiency of replacing the bracket must be improved to reduce the labor intensity of the workers.
