Description

Technical Field

[0001] The utility model belongs to the technical field of iron tapping trough detection, and in particular relates to an iron tapping trough erosion detection tool. Background Art

[0002] The taphole is an indispensable part of the blast furnace smelting process. Its main function is to safely guide the molten iron flowing out of the blast furnace to the molten iron tank or molten iron pretreatment facilities. The taphole is generally composed of the main ditch, iron ditch and slag ditch. The structure of each ditch is different due to the different materials it supports.

[0003] Molten iron passes through the trough for a long time, causing the working layer of the trough to be damaged by high temperature burning and other factors. During use, technicians are required to regularly perform erosion inspections on the trough to ensure the production quality of steel and the sustainable use of the trough. At present, technicians use their work experience to observe with the naked eye whether the working layer of the trough has fission or other unsafe phenomena. The quality of erosion inspection is limited. Sampling from the working layer is done by mechanical excavation, which is slow and difficult. In addition, existing workers use handheld ultrasonic thickness detection to operate the working layer directly and manually place the probe into the working layer of the trough during the thickness inspection. The pollutants and high temperature inside the working layer can easily cause harm to the workers.

[0004] In order to solve the above problems, this application proposes a taphole erosion detection tool. Utility Model Content

[0005] In order to solve the problems raised in the above background technology, the utility model provides a tapping channel erosion detection tool, which has the characteristics of simple operation and high safety.

[0006] To achieve the above purpose, the present invention provides the following technical solutions:

[0007] A tool for detecting erosion of an iron outlet groove comprises a base, a lifting mechanism is provided on the top of the base, a controller is also fixed on the top of the base, a lifting slider is provided on one side of the lifting mechanism, a mounting block is connected to one side of the lifting slider, a drilling rig is fixed to the bottom of the mounting block, a mounting shaft is connected to the main shaft end of the drilling rig, an index drill bit is connected to the bottom end of the mounting shaft, a spiral cutter rod is fixed to the inner middle part of the index drill bit, the bottom of the index drill bit is an open structure, and a plurality of crushing teeth are provided on the bottom edge of the index drill bit.

[0011] As a preferred embodiment of the iron outlet groove erosion detection tool of the present invention, a damping shaft is provided between the main support arm and the shaft seat, and between the main support arm and the auxiliary support arm.

[0013] As a preferred tool for detecting iron outlet groove erosion of the utility model, the insulating rod is a cylindrical structure, and a through hole is provided downwardly at the top of the insulating rod, a bolt is provided on one side of the through hole, and the data line can pass through the through hole.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. Through the index drill bit, samples can be quickly drilled from the working layer of the iron trough. The sampling cutter head of the index drill bit rises and falls synchronously with the lifting block of the lifting mechanism.

Through the setting of the lifting mechanism, the ultrasonic probe is connected to the data cable, and the end of the data cable extending upward is fixed on the end of the lifting mechanism. By adjusting the lifting structure, the ultrasonic probe can be moved. In the actual operation of detecting the thickness of the working layer, the staff manually moves and adjusts the height of the mechanical arm of the lifting mechanism according to the distance between the probe and the surface of the working layer to adjust the position of the ultrasonic probe. The staff does not need to have close contact with the working layer, and the non-contact detection is safer. Because it is placed vertically downward due to its own gravity, it has greater stability. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0026] The utility model provides Figures 1-6The illustrated tooling for detecting erosion of a taphole includes a base 6, a lifting mechanism 3 disposed on the top of the base 6, a controller 2 also fixed to the top of the base 6, a lifting slider disposed on one side of the lifting mechanism 3, a mounting block 4 connected to one side of the lifting slider, a drill 5 fixed to the bottom of the mounting block 4, a mounting shaft 18 connected to the end of the main shaft 17 of the drill 5, an indexing drill bit 16 connected to the bottom end of the mounting shaft 18, a spiral cutter rod 20 fixed to the middle portion of the inner portion of the indexing drill bit 16, an open bottom structure, and a plurality of crushing teeth 19 provided on the bottom edge of the indexing drill bit 16;

[0027] like Figure 2 As shown, the base 6 is placed on one side above the tapping trough working layer 15. The inner lining of the tapping trough working layer 15 is the part of the tapping trough structure that actually contacts the molten iron. When detecting the erosion condition of the working layer, by directly sampling from the working layer and then testing the sample with a dedicated machine, the degree of erosion of the working layer can be obtained, thereby determining whether the working layer needs to be replaced or other maintenance.

[0028] During the sampling process, the lifting mechanism 3 is started, and the lifting slider of the lifting mechanism 3 drives the mounting block 4 to move downward, and the mounting block 4 pushes the drill rig 5 to move downward, and the drill rig 5 pushes the index drill bit 16 close to the working layer and continues to move downward. When the drill rig 5 rotates, the spiral cutter rod 20 first contacts the working layer and punches a hole on the working layer, and then positions it to ensure the stability of the index drill bit 16. The index drill bit 16 continues to move downward, and the crushing teeth 19 at the bottom end of the index drill bit 16 continue to cut downward from the top of the working layer, and finally cut out a cylindrical sample. After the lifting mechanism 3 is reset, the drill rig 5 and the index drill bit 16 are brought back to their original positions, and then the sample is taken out of the index drill bit 16 to obtain the sample, and finally the sample is sent for inspection.

[0029] Specifically, such as Figure 4 As shown, the bottom end of the spiral cutter bar 20 extends downward to the outside of the index drill bit 16;

[0030] It should be noted that the specific working principle of the drilling rig 5 is the existing technology, and the working principle of the drilling rig 5 has been disclosed in the Chinese patent application number CN206747634U and the patent name Drilling Machine.

[0031] like Figure 1 、 Figure 2 and Figure 6 As shown, in another embodiment, a lifting mechanism is further provided on the top of the base 6, and the lifting mechanism includes a base 7, an axle seat 8 is provided on the top of the base 7, a rotatable main support arm 9 is provided on the top of the axle seat 8, the end of the main support arm 9 is connected to the auxiliary support arm 10, the end of the auxiliary support arm 10 is connected to the connecting arm 11, and the end of the connecting arm 11 is connected to the insulating rod 12.

[0032] A damping shaft 101 is provided between the main support arm 9 and the shaft seat 8, and between the main support arm 9 and the auxiliary support arm 10. A counterweight 21 is provided on the side wall of the base 7 and one end of the auxiliary support arm 10. The bottom of the base 7 is fixedly connected to the base 6 by bolts.

[0033] The user pulls or pushes the main support arm 9 by hand, and the end of the main support arm 9 rotates on the shaft seat 8, and under the action of the damping shaft 101, the main support arm 9 can rotate slowly. The same principle applies. When the user pulls or pushes the secondary support arm 10 by hand, the end of the secondary support arm 10 rotates at the end of the main support arm 9, and under the action of the damping shaft 101, the secondary support arm 10 can rotate slowly. It should be noted that the use of the damping shaft 101 is a prior art and does not affect the rotation of the main support arm 9 and the secondary support arm 10.

[0034] It should be noted that if Figure 1 and Figure 6 As shown, a data line 13 is connected to the insulating rod 12, one end of the data line 13 is connected to the ultrasonic probe 14, and the other end extends to the top of the base 6 and is connected to the ultrasonic detector 1. The insulating rod 12 is a cylindrical structure, and a through hole is provided downwardly at the top of the insulating rod 12, and a bolt is provided on one side of the through hole, and the data line 13 can pass through the through hole;

[0035] Specifically, the insulating rod 12 is made of rubber and has strong plasticity. It can be punched to facilitate the data line 13 to pass through the insulating rod 12. The data line 13 is then tightened with bolts to fix the data line 13, ensuring that the data line 13 will not slide on the data line 13. In the process of detecting the thickness of the working layer, the user manually operates the main support arm 9 and the auxiliary support arm 10 to make the insulating rod 12 drive the data line 13 to move, thereby driving the ultrasonic probe 14 to move, so that the ultrasonic probe 14 is close to the top surface of the working layer. After starting the ultrasonic detector 1, the ultrasonic probe 14 detects the thickness of the working layer. The utility model patent with the Chinese announcement number CN216246171U and the patent name of a coating thickness measuring device based on ultrasonic waves has disclosed the working principle of ultrasonic detection.

[0036] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents.
