[0002] Oxygen-enriched side-blown technology has been widely used in copper smelting, lead smelting, and solid waste treatment industries in my country, and is a typical example of molten pool smelting. The oxygen-enriched side-blown furnace is the core equipment of this technology, and its structural characteristics are a crucial factor affecting smelting efficiency and equipment performance. The fixed metallurgical furnace structures in nickel smelters and copper companies typically utilize spiral springs (i.e., tensioning springs) to adjust the furnace structure.

[0003] The side-blown furnace body is fixed by columns and compressed by springs. Numerous spiral springs are evenly distributed on the walls around the furnace body, with each spiral spring capable of applying a compression force of up to 50 tons. During each annual overhaul, the compression force of the spiral springs must be adjusted according to the condition of the furnace body.

[0004] During adjustment, the spiral spring needs to be tightened using a jack, and the locking nut on the spring rod needs to be rotated to return the spiral spring to the preset position.

[0005] The problem is that the compression force of the spiral spring is relatively large, the spiral spring is located on the furnace wall and the columns around the furnace, the maintenance space is small, and the placement and adjustment of the jack are difficult, which makes the adjustment of the spiral spring difficult. Utility Model Content

[0006] The purpose of this utility model is to provide an adjustment fixture for a side-blown furnace top spring, which aims to solve the technical problem that the placement and adjustment of the jack in a confined space is difficult, leading to difficulties in adjusting the spiral spring.

The support includes a vertically connected fixed plate and a support plate. The fixed plate is bolted to the column of the side-blown furnace. The top-tightening seat has a Z-shaped structure and includes a first top plate, a connecting plate, and a second top plate connected vertically in sequence. The first top plate is provided with an arched positioning groove for inserting a spring tie rod. The jack is respectively positioned between the column and the second top plate, and between the support plate and the first top plate.

[0008] Furthermore, the support plate has a first support plate vertically connected to it on one side, and the connecting plate has a second support plate vertically connected to it. The second support plate is located on one side of the second top plate, and both the first support plate and the second support plate are used to support the jack.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0019] Reference Figure 1 An adjustment fixture for a side-blown furnace top-tightening spring includes a top-tightening seat 50 and a support 60. The support 60 is disposed on the column 20 of the side-blown furnace, and the top-tightening seat 50 is disposed on one side of the top-tightening spring 30. A jack 40 is disposed between the support 60 and the top-tightening seat 50. The jack is used to press the top-tightening spring 30. The position of the adjusting locking nut 32 on the spring rod 31 is rotated to adjust the top-tightening spring 30 back to the preset position.

[0020] Example 1

[0021] The top clamp 50 has a Z-shaped structure to accommodate the narrow space between the wall 10 and the column 20 (see reference). Figure 2 The top clamping seat includes a first top plate 51, a connecting plate 52, and a second top plate 53 connected vertically in sequence. The first top plate 51, the second top plate 52, and the third top plate 53 have the same width. The length of the first top plate 51 is greater than the length of the second top plate 53. The first top plate 51 is provided with an arched positioning groove 54, which is used to fit onto the outside of the spring tie rod 31. The arched positioning groove 54 is located on the side of the first top plate 51 near the connecting plate 52.

[0022] Reference Figure 3 The support 60 includes a fixed plate 61 and a support plate 62 connected vertically. One side of the support plate 62 is used to support the jack 40, and the other side is provided with a reinforcing rib 63 between it and the fixed plate 61. The fixed plate 61 is provided with a connecting hole 611. The fixed plate 61 is connected to the column 20 of the side-blown furnace by bolts.

[0023] The working process of Example 1:

[0024] The space between the column 20 and the wall 10 is narrow, and the clamping spring 30 and the spring rod 31 are installed in combination between the wall 10 and the column 20.

[0025] First, remove the crossbeam between the columns 20 to expose the space on one side of the column 20, as well as the screw holes on the column 20 for connecting with the crossbeam;

[0026] Then, align the connecting hole 611 of the fixing plate 61 on the support 60 with the screw hole of the column 20, and fix the support 60 to the column 20 with bolts, so that the support plate 62 is parallel to the wall 10.

[0027] Next, the arched positioning groove 54 is placed on the top spring 30, so that the spring rod passes through the arched positioning groove 54. At this time, the locking nut 32 is located on one side of the first top plate 51, and the second top plate 53 is located in the narrow space between the wall 10 and the column 20. Since the first top plate 51 is relatively long, the first top plate 51 extends to one side of the column 20, that is, one edge of the first top plate 51 is aligned with the edge of the support plate 62 of the support 60. At this time, the support plate 62 is parallel to the first top plate 51.

[0028] Finally, jacks 40 are installed between the support plate 62 and the first top plate 51, and between the column 20 and the second top plate 53. The jacks 40 on both sides are used to compress the clamping spring 30. The adjusting locking nut 32 is rotated to rotate to the preset position. The jacks 40 are slowly removed so that the clamping spring 30 and the locking nut 32 are pressed together. The clamping seat 50 and the support 60 are disassembled and the crossbeam is reinstalled, thereby completing the pressure adjustment of the clamping spring 30.

[0029] Example 2

[0030] Example 2 is a further improvement on Example 1, as detailed below:

[0031] Reference Figure 3 The support plate 62 is provided with a first support plate 82 perpendicular to it, which is used to assist in supporting the jack 40.

[0032] Reference Figure 4 The connecting plate 52 is provided with a second support plate 81, which is perpendicularly connected to the connecting plate 52. The second support plate 81 is located on one side of the second top plate 83 on the connecting plate 52. The second support plate 81 is used to assist in supporting the jack 40.

[0033] The working process of this embodiment follows that of Embodiment 1, and is described in detail as follows:

[0034] When the support 60 is fixed to one side of the column 20, the first support plate 82 is set in a horizontal direction. The jack 40 is placed horizontally on the upper surface of the first support plate 82, eliminating the need for manual lifting of the jack 40 and making it easier to adjust and operate the jack 40.

[0035] After the spring rod 32 passes through the arched positioning groove 54, the second support plate 81 is set in a horizontal direction. The jack 40 is placed horizontally on the upper surface of the second support plate 81, which facilitates manual operation and adjustment of the jack 40.

[0036] Example 3

[0037] Example 3 is a further improvement based on Example 1, as detailed below:

[0038] Reference Figure 2A first stiffener 71 is provided on the edge opposite to the arched positioning groove 54 on the first top plate 51. The first stiffener 71 is rectangular and is perpendicularly connected to the first top plate 51. A second stiffener 72 is provided on the first top plate 51 opposite to the connecting plate 52. The second stiffener 72 is parallel to the connecting plate 52 and is perpendicularly connected to one side of the first stiffener 71. The other side of the first stiffener 71 is perpendicularly connected to the connecting plate 52. The second stiffener 72 is triangular.

[0039] Reference Figure 4 Two third stiffeners 73 are provided on both sides of the second top plate 53. The third stiffeners 73 are right-angled triangles. One right-angled side of the third stiffener 73 is perpendicularly connected to the second top plate 53, and the other right-angled side is perpendicularly connected to the connecting plate 52.

[0040] In this embodiment, the first stiffener 71, the second stiffener 72, and the third stiffener 73 are mainly used to enhance the overall support strength of the top clamping seat.

[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
