Description

Technical Field

[0001] This utility model relates to the field of molten iron sampling technology, specifically to a movable adapter for the main and auxiliary rods of an automatic molten iron ladle sampler. Background Technology

[0002] Currently, automatic molten iron ladle sampling machines generally use a main rod and a secondary rod together for sampling. Before operation, the main rod and the secondary rod need to be threaded together as one unit, and then the secondary rod can be fixedly connected to the molten iron sampler.

[0003] The aforementioned traditional main rod and auxiliary rod structure is relatively simple, but it faces many technical challenges in actual operation:

[0004] 1. Because the connection between the main rod and the auxiliary rod is a threaded connection, each time the auxiliary rod is replaced, the end of the other auxiliary rod needs to be sent to the machine repair shop to have external threads machined before it can be used with the main rod, which is quite troublesome;

[0005] 2. Since the slag thickness in the molten iron ladle is uncontrollable and unpredictable, the insertion depth of the auxiliary rod and the main rod may be too deep, resulting in the threaded connection of the main rod and the auxiliary rod being submerged in molten iron. This causes the threaded connection to be stuck together by the molten iron, making it difficult to separate the main rod and the auxiliary rod manually. Cutting or welding is required for repair.

[0006] 3. If the molten iron frequently submerges the main rod, this will require multiple repairs or prolonged repairs, causing the connection clearance between the main rod and external equipment to change continuously, thus affecting the clamping and use of the main rod.

[0007] Therefore, we have made technical improvements to address the structural defects of traditional main rods and auxiliary rods in order to meet usage requirements. Utility Model Content

[0008] The technical problem to be solved by this utility model is to address the shortcomings of the existing technology by providing a movable adapter for the main and auxiliary sampling rods of an automatic molten iron ladle sampler, which is easy to install, requires no additional thread processing when replacing the auxiliary rod, simplifies the pre-operation preparation process, and reduces losses.

[0009] The technical problem to be solved by this utility model is achieved through the following technical solution: a movable adapter for the main and auxiliary rods of an automatic iron ladle sampler, comprising:

[0010] The sampling rod has one end set as the clamping end and the other end set as the connecting end, and a threaded hole I is opened on the end face of the connecting end;

[0011] The sampling rod connector has an upper connection end at one end and a lower connection end at the other end. An external threaded post that can be threadedly connected to threaded hole I is fixed on the end face of the upper connection end, and an insertion hole is opened on the end face of the lower connection end.

[0012] The sampling rod has one end configured as an insertion end that can be inserted into the socket, and the other end configured as a fixing end for fixing to an external molten iron sampling container.

[0013] Several threaded holes II are provided on the outer circumferential surface of the sampling rod connector, which are connected to the insertion hole. The sampling rod in the insertion hole is locked in the insertion hole by bolts fasteners that are threaded into the threaded holes II.

[0014] The technical problem to be solved by this utility model can also be achieved through the following technical solution: the sampling main and auxiliary rod movable adapter of the automatic iron ladle sampling machine described above, wherein the axes of the sampling main rod, threaded hole I, sampling rod connector, insertion hole and sampling auxiliary rod are collinear.

[0015] The technical problem to be solved by this utility model can also be achieved through the following technical solution: the movable adapter of the main and auxiliary rods of the automatic iron ladle sampling machine described above, wherein the axis of the threaded hole II is perpendicular to the axis of the sampling rod connector.

[0016] The technical problem to be solved by this utility model can also be achieved through the following technical solution: the above-mentioned automatic sampling machine for molten iron ladle has two threaded holes II, and the axes of the two threaded holes II are parallel.

[0017] Compared with the prior art, the beneficial technical effects of this utility model are as follows: the sampling main rod is detachably installed with the sampling auxiliary rod through the sampling rod connector, which is simple to install. In addition, the sampling auxiliary rod is replaced by a non-threaded connection instead of a traditional threaded connection. This means that when sampling materials, the sampling auxiliary rod only needs to cut the scrap 16# threaded steel bars in the steel plant, and there is no need to process the external threads. The manufacturing cost is low and the practicality is strong. Attached Figure Description

[0020] The specific technical solutions of this utility model are further described below with reference to the accompanying drawings, so as to enable those skilled in the art to further understand this utility model, without constituting a limitation on its rights.

[0021] Example 1, referring to Figure 1 A movable adapter for the main and auxiliary sampling rods of an automatic iron ladle sampler, comprising:

[0022] The sampling main rod is formed into a roughly cylindrical rod structure. Its size and specifications can be selected according to the usage requirements. One end is set as the clamping end 1 and the other end is set as the connecting end 2. A threaded hole I10 is opened on the end face of the connecting end 2. The diameter of the threaded hole I10 can be selected according to the usage requirements.

[0023] The sampling rod connector is formed into a roughly cylindrical structure. One end is designated as the upper connecting end 3 and the other end as the lower connecting end 4. An external threaded post 5 that can be threadedly connected to the threaded hole I10 is fixed on the end face of the upper connecting end 3. An insertion hole 6 is provided on the end face of the lower connecting end 4. The insertion hole 6 is a cylindrical hole.

[0024] The sampling auxiliary rod is formed into a roughly cylindrical structure, with one end being an insertion end 7 that can be inserted into the insertion hole 6, and the other end being a fixing end 8 for fixing to an external molten iron sampling container (not shown in the figure).

[0025] Several threaded holes II9 are provided on the outer circumferential surface of the sampling rod connector, which are connected to the insertion hole 6. The diameter of the threaded holes II9 can be selected according to the usage requirements. The axis of the threaded holes II9 is ​​perpendicular to the axis of the sampling rod connector. The sampling auxiliary rod in the insertion hole 6 is locked in the insertion hole 6 by bolts fasteners threaded in the threaded holes II9. The axes of the sampling main rod, threaded hole I10, sampling rod connector, insertion hole 6 and sampling auxiliary rod are collinear.

[0026] The aforementioned threaded hole II9 is ​​provided in two parts, and the axes of the two threaded holes II9 are parallel. The number of threaded holes II9 can be selected according to the usage requirements and is not limited to two.

[0027] When using the movable adapter for the main and auxiliary sampling rods of this automatic molten iron ladle sampler, we only need to thread the threaded hole I10 of the main sampling rod to the external threaded post 5 of the sampling rod connector, then insert the insertion end 7 of the auxiliary sampling rod into the insertion hole 6 of the sampling rod connector, then thread the external bolt fastener into the threaded hole II9, and finally fix the external molten iron sampling container that can hold molten iron to the fixed end 8 of the auxiliary sampling rod. This fixing method can be welding or plugging. The clamped end 1 of the main sampling rod can be clamped and raised and lowered by external equipment to perform molten iron sampling.

[0028] Compared with the traditional main rod and auxiliary rod structure, the installation and connection method of the sampling main rod, sampling rod connector and sampling auxiliary rod in Example 1 is more reasonable, with a low maintenance rate. Moreover, the sampling auxiliary rod only needs to be cut from the scrap 16# threaded steel bars in the steel plant when sourcing materials, and there is no need to process the external threads, resulting in low manufacturing cost.
