Description

Technical Field

[0001] This utility model belongs to the technical field of assembly auxiliary devices, specifically relating to a positioning tool for assembling and positioning the straight air supply pipe of an ironmaking blast furnace. Background Technology

[0002] In the operation of blast furnaces, the straight air supply pipe is a key part that is directly connected to the tuyeres of the blast furnace. The pulverized coal injection pipe is inserted into the straight air supply pipe and reaches the tuyeres, so that the pulverized coal is sent into the tuyeres for combustion, providing a continuous source of heat to the blast furnace to reach the temperature required for ironmaking.

[0003] Currently, in the use of straight air supply pipes, the tilt angle of the pulverized coal injection pipe relative to the straight air supply pipe is an important factor affecting the pulverized coal injection effect. Inaccurate positioning accuracy of the pulverized coal injection pipe angle not only affects pulverized coal injection, but also causes premature wear of the sleeve, thus affecting the operation of the blast furnace.

[0004] However, as described in Chinese invention patent application number "201510125021.0", in the existing assembly process of air supply pipe and pulverized coal injection pipe, the horizontally placed air supply pipe is usually supported by a fixed height support. It is difficult to make slight adjustments to the tilt angle of the air supply pipe, which can easily lead to low assembly positioning accuracy and thus affect the structural quality of the entire air supply device. Utility Model Content

[0005] The technical problem to be solved by this utility model is how to improve the accuracy of assembling and positioning the blast furnace air supply pipe and pulverized coal injection pipe. In view of the shortcomings of the existing technology, this utility model provides an assembly and positioning tooling for the blast furnace air supply pipe.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: This utility model provides an assembly and positioning fixture for a blast furnace blast pipe, including a base, a locking mechanism, a support mechanism, and an adjustment mechanism. The locking mechanism, the support mechanism, and the adjustment mechanism are spaced apart on the base. The locking mechanism is used to detachably connect one end of the air inlet of the horizontally placed blast pipe and is used to move closer to or away from the support mechanism along the base. The support mechanism is used to place one end of the air outlet of the blast pipe and to drive the air outlet end to reciprocate vertically. The adjustment mechanism is used to move closer to or away from the support mechanism along the base. When the adjustment mechanism moves closer to the support mechanism, it is used to drive the end of the pulverized coal injection pipe inside the opening of the air outlet end to move up and down.

[0007] Compared to existing technologies, the advantages of this utility model include: A base, a locking mechanism, a support mechanism, and an adjustment mechanism are used to assemble and position the blast furnace air supply pipe. The locking mechanism, support mechanism, and adjustment mechanism are spaced apart on the base. The locking mechanism can be detachably connected to the air inlet end of the air supply pipe, thus initially ensuring the stability of the air supply pipe. Simultaneously, the support mechanism can be used to place the air outlet end of the air supply pipe, providing stable support and cooperating with the locking mechanism to ensure the stability of the air supply pipe during assembly. Furthermore, the adjustment mechanism can move closer to or further away from the support mechanism along the base. When the adjustment mechanism moves closer to the support mechanism, it can drive the end of the pulverized coal injection pipe inside the opening at the air outlet end to move up and down. Thus, after the pulverized coal injection pipe is inserted, the movement of the adjustment mechanism enables a driving connection with the end of the pulverized coal injection pipe. The adjustment mechanism drives the end of the pulverized coal injection pipe to move up and down, thereby adjusting the tilt angle of the pulverized coal injection pipe relative to the axial direction of the air supply pipe. This allows for precise adjustment of the pulverized coal injection pipe, effectively improving the accuracy of assembling and positioning the air supply pipe and pulverized coal injection pipe in the blast furnace. Furthermore, the locking mechanism can move closer to or further away from the support mechanism along the base, allowing for adjustment of the distance between the locking mechanism and the support mechanism. This facilitates the placement and assembly of air supply pipes of different lengths, effectively expanding the applicability. Simultaneously, the support mechanism can drive one end of the air outlet to move back and forth vertically, adjusting the height of the air outlet end of the air supply pipe. This keeps the entire air supply pipe axially horizontal, further ensuring the convenience and accuracy of subsequent adjustment of the tilt angle of the pulverized coal injection pipe relative to the axial direction of the air supply pipe, further improving the accuracy of assembling and positioning the air supply pipe and pulverized coal injection pipe in the blast furnace.

[0024] An embodiment of this utility model provides an assembly and positioning fixture for a blast furnace air supply pipe, including a base 1, a locking mechanism 2, a support mechanism 3, and an adjustment mechanism 4. The locking mechanism 2, the support mechanism 3, and the adjustment mechanism 4 are spaced apart on the base 1. The locking mechanism 2 is used to detachably connect one end of the air supply pipe 5, which is placed horizontally, and is used to move closer to or away from the support mechanism 3 along the base 1. The support mechanism 3 is used to place one end of the air supply pipe 5, which is placed, and is used to drive one end of the air supply pipe 5 to move back and forth in the vertical direction. The adjustment mechanism 4 is used to move closer to or away from the support mechanism 3 along the base 1. When the adjustment mechanism 4 moves closer to the support mechanism 3, the adjustment mechanism 4 is used to drive the end of the pulverized coal injection pipe 51 in the opening of one end of the air supply pipe to move up and down.

[0025] Specifically, such as Figure 2 and Figure 3 As shown, the horizontal direction is parallel to the XY plane, and the vertical direction is the Z-axis direction; as Figure 1As shown, the air inlet of the air supply duct 5 is the left side opening of the air supply duct 5 in the horizontal direction, and the air outlet of the air supply duct 5 is the right side opening of the air supply duct 5 in the horizontal direction; as Figure 1 and Figure 2 As shown, the outer wall of the air supply pipe 5 is covered by a shell to form a cavity. The pulverized coal injection pipe 51 passes through the cavity and the air supply pipe 5 from the outside of the shell and forms a certain angle with the axial direction of the air supply pipe 5.

[0026] In this embodiment, as Figure 1 and Figure 2 As shown, a base 1, a locking mechanism 2, a support mechanism 3, and an adjusting mechanism 4 are arranged to form a positioning fixture for assembling the blast furnace air supply pipe. The locking mechanism 2, support mechanism 3, and adjusting mechanism 4 are spaced apart on the base 1. The locking mechanism 2 can be detachably connected to one end of the air supply pipe 5's inlet, thus initially ensuring the stability of the air supply pipe 5. Simultaneously, the support mechanism 3 can be used to place one end of the air supply pipe 5's outlet, providing stable support for the air supply pipe 5 and cooperating with the locking mechanism 2 to ensure the stability of the air supply pipe 5 during assembly. Furthermore, the adjusting mechanism 4 can move closer to or further away from the support mechanism 3 along the base 1. When the adjusting mechanism 4 moves closer to the support mechanism 3, it can drive the end of the pulverized coal injection pipe 51 inside the opening at the outlet to move up and down. Thus, after the pulverized coal injection pipe 51 is inserted, the movement of the adjusting mechanism 4 achieves a driving connection with the end of the pulverized coal injection pipe 51, thereby enabling the air supply pipe to move up and down. The adjustment mechanism 4 drives the end of the pulverized coal injection pipe 51 to move up and down, thereby adjusting the tilt angle of the pulverized coal injection pipe 51 relative to the axial direction of the air supply pipe 5, thus achieving precise adjustment of the pulverized coal injection pipe 51 and effectively improving the accuracy of the assembly and positioning of the air supply pipe and pulverized coal injection pipe in the blast furnace. In addition, the locking mechanism 2 can move closer to or further away from the support mechanism 3 along the base 1, so that the distance between the locking mechanism 2 and the support mechanism 3 can be adjusted to facilitate the placement and assembly of air supply pipes 5 of different lengths, effectively improving the applicability. At the same time, the support mechanism 3 can drive one end of the air outlet to move back and forth in the vertical direction, thereby adjusting the height of the air outlet end of the air supply pipe 5, so that the axial direction of the entire air supply pipe 5 is kept in the horizontal direction, further ensuring the convenience and accuracy of the subsequent adjustment of the tilt angle of the pulverized coal injection pipe 51 relative to the axial direction of the air supply pipe 5, and further improving the accuracy of the assembly and positioning of the air supply pipe and pulverized coal injection pipe in the blast furnace.

[0027] Optionally, the locking mechanism 2 includes a first support frame 21, a support plate 22, and locking blocks 23. The first support frame 21 is mounted on the base 1, and the support plate 22 is mounted on the first support frame 21 and located on the side of the first support frame 21 facing the support mechanism 3. There are multiple locking blocks 23, which are arranged at equal intervals on the support plate 22 in the horizontal direction. Two locking blocks 23 that are symmetrical about the horizontal direction are used to abut against the two inner side walls of the air inlet end that are opposite to each other in the opening direction.

[0028] Specifically, there are 4 card blocks 23.

[0029] In this optional embodiment, such as Figure 2 As shown, a locking mechanism 2 is formed by a first support frame 21, a support plate 22, and a locking block 23. The first support frame 21 is mounted on the base 1, the support plate 22 is mounted on the first support frame 21, and the locking block is located on the support plate 22, thereby ensuring the structural stability of the entire locking mechanism 2 on the base 1. In addition, the support plate 22 is located on the side of the first support frame 21 facing the support mechanism 3, and there are multiple locking blocks 23. The multiple locking blocks 23 are arranged at equal intervals in the horizontal direction on the support plate 22. Two locking blocks 23 that are symmetrical about the horizontal direction can respectively abut against the two inner side walls of the air inlet end with opposite opening directions. In this way, the paired locking blocks 23 can cooperate to provide opposite support forces to the opposite side walls of the air inlet end of the air supply straight pipe 5, thereby achieving effective locking of the air inlet end and ensuring the positioning stability of the air supply straight pipe 5.

[0030] Optionally, the locking mechanism 2 further includes a first telescopic drive member 24. There are multiple first telescopic drive members 24, which are arranged at equal intervals around the horizontal direction on the support plate 22 and are connected to multiple locking blocks 23 in a one-to-one correspondence. The first telescopic drive members 24 are used to drive the locking blocks 23 to move closer to or away from another locking block 23 that is symmetrical about the horizontal direction.

[0031] Specifically, the first telescopic drive component 24 can be a telescopic hydraulic cylinder or a telescopic electric cylinder, etc.; the number of the first telescopic drive components 24 is the same as the number of the locking blocks 23.

[0032] In this optional embodiment, such as Figure 3 As shown, the locking mechanism 2 is also provided with a first telescopic drive member 24. There are multiple first telescopic drive members 24, which are arranged at equal intervals on the support plate 22 in the horizontal direction. In this way, the first telescopic drive members 24 can be connected to multiple locking blocks 23 one by one. Then, the first telescopic drive members 24 drive the locking blocks 23 to move closer to or away from another locking block 23 that is symmetrical about the horizontal direction. This reduces or increases the distance between the two pairs of locking blocks 23. At this time, not only can the driving force of the first telescopic drive members 24 make the locking blocks 23 tightly abut against the inner wall of the air outlet end, thereby improving the locking stability of the air inlet end, but also the movement of the locking blocks 23 can effectively lock the air outlet end of the air supply straight pipe 5 with different inner diameters, effectively improving the applicability range.

[0033] Optionally, the locking mechanism 2 also includes a limiting plate 25, which has multiple limiting plates 25 arranged at equal intervals on the support plate 22 in a horizontal direction. The limiting plates 25 are used to abut against the end face of one end of the air inlet.

[0034] Specifically, the extension dimension of the limiting plate 25 along the axial direction of the support plate 22 is greater than or equal to the farthest distance that the locking block 23 can move relative to the center of the support plate 22, so as to ensure that the limiting plate 25 is stably abutted against the end face of the air inlet; the number of limiting plates 25 and locking blocks 23 is the same.

[0035] In this optional embodiment, to prevent the air supply straight pipe 5 from moving axially, such as... Figure 3 As shown, the locking mechanism 2 is also provided with limiting plates 25. There are multiple limiting plates 25, which are arranged at equal intervals on the support plate 22 in the horizontal direction. At the same time, the limiting plates 25 can abut against the end face of one end of the air inlet. With this arrangement, after the air supply pipe 5 is locked by the locking block 23, the abutment between the limiting plates 25 and the end face of one end of the air inlet can effectively prevent the air supply pipe 5 from shifting in the axial direction, thereby ensuring the stability of the air supply pipe 5 during assembly.

[0036] Optionally, the locking mechanism 2 further includes a first rotary drive 26, which is mounted on the first support frame 21. The axial direction of the support disk 22 is parallel to the horizontal direction. The first rotary drive 26 is driven to connect with the support disk 22 and is used to drive the support disk 22 to rotate around the horizontal direction. The locking block 23 is located on the end face of the support disk 22 facing the support mechanism 3 in the horizontal direction.

[0037] Specifically, the first rotary drive component 26 is a rotary motor or a servo motor, etc.

[0038] In this optional embodiment, to ensure that the position of the air supply straight pipe 5 for inserting into the pulverized coal injection pipe 51 is at the top, so as to facilitate the insertion of the pulverized coal injection pipe 51, such as... Figure 3 and Figure 4 As shown, the locking mechanism 2 is also provided with a first rotary drive component 26, which is mounted on the first support frame 21 to ensure the working stability of the first rotary drive component 26. On this basis, the axial direction of the support plate 22 is set to be parallel to the horizontal direction, and the first rotary drive component 26 is driven to connect with the support plate 22, so that the support plate 22 can be driven to rotate around the horizontal direction. The locking block 23 is located on the end face of the support plate 22 facing the support mechanism 3 in the horizontal direction. With this configuration, after the locking block 23 engages with the air supply straight pipe 5, the rotation of the support plate 22 can drive the rotation of the air supply straight pipe 5, thereby realizing the stable adjustment of the position of the air supply straight pipe 5 and ensuring the convenient insertion of the subsequent pulverized coal injection pipe 51.

[0039] Optionally, the engaging mechanism 2 further includes a first slide rail 27 and a second telescopic drive member. The first slide rail 27 is mounted on the base 1, and the first support frame 21 is slidably mounted on the first slide rail 27 and drivenly connected to the second telescopic drive member. The second telescopic drive member is used to drive the first support frame 21 to move closer to or away from the support mechanism 3 along the first slide rail 27.

[0040] Specifically, the second telescopic drive component is a telescopic electric cylinder or a telescopic hydraulic cylinder, etc.

[0041] In this optional embodiment, in order to achieve stable sliding of the locking mechanism 2 on the base 1, as shown in the figure and Figure 4 As shown, the engaging mechanism 2 is also provided with a first slide rail 27 and a second telescopic drive member. The first slide rail 27 is mounted on the base 1, and the first support frame 21 is slidably mounted on the first slide rail 27. Thus, the first slide rail 27 and the base 1 cooperate to ensure the smooth and stable sliding of the first support frame 21. On this basis, the first support frame 21 is driven to connect with the second telescopic drive member. In this way, the second telescopic drive member can drive the first support frame 21 to move closer to or away from the support mechanism 3 along the first slide rail 27, thereby realizing the stable sliding of the engaging mechanism 2 on the base 1.

[0042] Optionally, the support mechanism 3 includes a first bracket 31, a second bracket 32, and a sliding support 33. The sliding support 33 is mounted on the base 1. The first bracket 31 and the second bracket 32 ​​are arranged crosswise and are hinged at the intersection in the horizontal direction. The lower ends of the first bracket 31 and the lower ends of the second bracket 32 ​​are slidably mounted on the sliding support 33 so that they are close to or far apart from each other.

[0043] In this optional embodiment, such as Figure 1 , Figure 3 and Figure 4 As shown, a support mechanism 3 is formed by a first bracket 31, a second bracket 32, and a sliding support 33. The sliding support 33 is mounted on the base 1 to ensure the structural stability of the entire support mechanism 3. Based on this, the first bracket 31 and the second bracket 32 ​​are arranged crosswise, and the intersection is hinged horizontally, so that the first bracket 31 and the second bracket 32 ​​can rotate relative to each other. At the same time, the lower ends of the first bracket 31 and the lower ends of the second bracket 32 ​​are slidably mounted on the sliding support 33. In this way, when the first bracket 31 and the second bracket 32 ​​rotate relative to each other, the lower ends of the first bracket 31 and the lower ends of the second bracket 32 ​​can move closer or further away from each other, so that the upper ends of the first bracket 31 and the upper ends of the second bracket 32 ​​rise or fall, thereby driving one end of the air outlet on them to rise or fall, realizing the stable adjustment of the air supply pipe 5.

[0044] Optionally, the sliding support 33 is provided with a sliding groove 331 extending along a first direction, which is parallel to the horizontal direction and is used to be perpendicular to the opening direction of the air supply pipe 5. The lower end of the first support 31 and the lower end of the second support 32 are both connected to a sliding rod 34 that is slidably installed in the sliding groove 331. The upper end of the first support 31 and the upper end of the second support 32 are both rotatably installed with pulleys 35 around the horizontal direction.

[0045] Specifically, such as Figure 3As shown, the first direction is the X-axis direction.

[0046] In this optional embodiment, such as Figure 3 and Figure 4 As shown, to ensure the stability of the movement of the first support 31 and the second support 32, a sliding groove 331 extending along a first direction is provided on the sliding support 33. The first direction is parallel to the horizontal direction and can also be perpendicular to the opening direction of the air supply pipe 5. The lower ends of the first support 31 and the second support 32 are both connected to sliding rods 34 that are slidably installed in the sliding groove 331. With this configuration, the sliding rods 34 can move back and forth along the sliding groove 331, thereby causing the lower ends of the first support 31 and the second support 32 to move closer or further apart, ensuring the stability of the movement of the first support 31 and the second support 32. On this basis, pulleys 35 are rotatably installed on the upper ends of the first support 31 and the upper ends of the second support 32 around the horizontal direction. With this configuration, the wheel surface of the pulleys 35 can fit against the outer wall of the air supply pipe 5, so that the friction between the entire support mechanism 3 and the air supply pipe 5 is rolling friction, thereby avoiding friction from becoming an obstacle in the driving process of the support mechanism 3 on the air supply pipe 5, and thus ensuring the smoothness of the assembly and positioning of the air supply pipe 5.

[0047] Optionally, the adjustment mechanism 4 includes a second support frame 41, a second slide rail 42, a third telescopic drive member, and an adjustment component 43. The second slide rail 42 is mounted on the base 1. The second support frame 41 is slidably mounted on the second slide rail 42 and is drivenly connected to the third telescopic drive member. The third telescopic drive member is used to drive the second support frame 41 to move closer to or away from the support mechanism 3 along the second slide rail 42. The adjustment component 43 is mounted on the second support frame 41 and is used to drive the end of the pulverized coal injection pipe 51 to move up and down.

[0048] Specifically, the third telescopic drive component is a telescopic electric cylinder or a telescopic hydraulic cylinder.

[0049] In this optional embodiment, such as Figure 3 and Figure 4As shown, an adjustment mechanism 4 is composed of a second support frame 41, a second slide rail 42, a third telescopic drive component, and an adjustment component 43. The second slide rail 42 is mounted on the base 1, and the second support frame 41 is slidably mounted on the second slide rail 42, thereby ensuring the sliding stability of the second support frame 41 on the base 1. At the same time, the second support frame 41 is driven to move along the second slide rail 42 towards or away from the support mechanism 3, so that the adjustment mechanism 4 moves towards or away from the end of the pulverized coal injection pipe 51. On this basis, the adjustment component 43 is mounted on the second support frame 41. The adjustment component 43 can drive the end of the pulverized coal injection pipe 51 to move up and down. Thus, when the second support frame 41 is close to the support mechanism 3, the adjustment component 43 can be driven to connect with the end of the pulverized coal injection pipe 51 to adjust the tilt angle of the pulverized coal injection pipe 51.

[0050] Optionally, the adjustment assembly 43 includes a second rotary drive 431 and an adjustment rod 432. The second rotary drive 431 is mounted on the second support frame 41. The adjustment rod 432 extends horizontally and is inclined downward relative to the horizontal direction at one end near the support mechanism 3 so as to abut against the lower bottom wall of the end of the pulverized coal injection pipe 51. The second rotary drive 431 is driven to the middle section of the adjustment rod 432 and drives the adjustment rod 432 to rotate around a second direction so that the end of the adjustment rod 432 near the support mechanism 3 moves up and down. The second direction is parallel to the horizontal direction and is perpendicular to the opening direction of the air supply straight pipe 5.

[0051] Specifically, the second rotary drive component 431 is a rotary motor or a servo motor, such as... Figure 3 As shown, the second direction is the X-axis direction.

[0052] In this optional embodiment, in order to ensure precise adjustment of the tilt angle of the pulverized coal injection pipe 51, such as Figure 2 and Figure 4 As shown, an adjustment assembly 43 is formed by a second rotary drive 431 and an adjusting rod 432. The second rotary drive 431 is mounted on the second support frame 41, while the adjusting rod 432 extends horizontally. The end of the adjusting rod 432 near the support mechanism 3 is inclined downward relative to the horizontal direction. Thus, when the second support frame 41 is close to the support mechanism 3, the end of the adjusting rod 432 near the support mechanism 3 can abut against the lower bottom wall of the end of the pulverized coal injection pipe 51. At the same time, the second rotary drive 431 is driven to the middle section of the adjusting rod 432, thereby driving the adjusting rod 432 to rotate around a second direction. The second direction is parallel to the horizontal direction and perpendicular to the opening direction of the air supply straight pipe 5. This allows the end of the adjusting rod 432 near the support mechanism 3 to move up and down, thereby driving the end of the pulverized coal injection pipe 51 to move up and down, achieving precise adjustment of the tilt angle of the pulverized coal injection pipe 51.
