Description

Technical Field

[0001] This utility model belongs to the field of powder metallurgy technology, and specifically relates to a baking device for an oven. Background Technology

[0002] Powder metallurgy is a process technology that uses metal powders (or mixtures of metal and non-metal powders) as raw materials, and manufactures metallic materials, composite materials, and various types of products through forming and sintering. In the above production process, the ladle in the oven needs to be heated and dried using a baking oven.

[0003] In actual production, the position of the oven needs to be adjusted according to different working conditions. In existing technologies, a support frame is typically used to move the oven; common types include vertically tilting supports and horizontally swinging supports. Vertically tilting supports use a hinged structure to allow the oven to tilt vertically around a horizontal axis. While the structure is relatively simple, its vertical tilting stroke is large, it occupies a lot of space, and it is prone to interfering with other equipment in the workshop. Furthermore, this method makes it difficult to precisely control the height of the oven, and it is difficult to adapt to ovens of different heights. Horizontally swinging supports, while overcoming the spatial limitations of vertical tilting to some extent, have a limited swing range and cannot adjust the distance between the oven and the oven, making it difficult to meet the diverse needs for baking angles and distances under different working conditions.

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.

[0052] The powder metallurgy drying furnace 20 is typically hoisted onto a maintenance platform 10 nearly three meters high. A slag discharge bin is located beneath the maintenance platform 10, which is surrounded by a steel structure wall 30. Space in industrial sites is usually very limited. Furthermore, the drying furnace 20 comes in various sizes, and its position on the maintenance platform 10 varies with each hoisting. Therefore, conventional vertical tilting supports and horizontal swing supports cannot meet the requirements for optimizing space layout and precisely adjusting the position of the drying equipment to fit the furnace.

[0053] To resolve the above issues, please refer to the following: Figures 1 to 7 The present invention provides a baking device for an oven. The baking device includes a column 1, a cantilever beam 2, and a baking device 5. The column 1 is mounted on a maintenance platform 10. The cantilever beam 2 includes a first beam 21 and a second beam 22. The first beam 21 is rotatably connected to the top of the column 1 via a rotary drive assembly 3. The inner end of the second beam 22 is slidably connected to the first beam 21 via a telescopic drive assembly 4. The outer end of the second beam 22 is provided with a chain lifting assembly 6. The baking device 5 is connected to the chain 61 of the chain lifting assembly 6. The rotary drive assembly 3 is used to drive the cantilever beam 2 and the baking device 5 to swing horizontally, the telescopic drive assembly 4 is used to drive the second beam 22 and the baking device 5 to extend and retract horizontally, and the chain lifting assembly 6 is used to drive the baking device 5 to rise and fall.

[0054] This embodiment provides a baking device for an oven. The column 1 provides a stable support foundation for the entire baking device. The cantilever beam 2 is set as a separate structure of a first beam 21 and a second beam 22. The first beam 21 is rotatably connected to the column 1, and the second beam 22 is slidably connected to the first beam 21. This realizes the horizontal swing and horizontal extension of the baking device 5, which facilitates the precise adjustment of the installation angle and horizontal distance between the baking device 5 and the oven 20, thereby adapting to the oven 20 at different hoisting positions. On this basis, the chain lifting assembly 6 drives the baking device 5 to rise and fall through the chain 61, which facilitates the adjustment of the installation height of the baking device 5 to adapt to the oven 20 at different heights. At the same time, the flexible chain 61 makes the overall structure more compact, which helps to reduce the overall height of the device and further reduce the space occupation.

[0055] Compared with the prior art, the baking device for oven provided in this embodiment can realize multi-dimensional flexible adjustment of the installation angle, horizontal installation distance and vertical height of the baking device 5, which is convenient to adapt to the baking needs of the oven 20 under different working conditions. Moreover, the overall structure is compact and significantly optimizes the spatial layout of the industrial site.

[0056] Specifically, the column 1, the first beam 21, and the second beam 22 are all constructed from welded steel sections and have internal cavities, ensuring load-bearing strength while also helping to reduce weight. The bottom of the column 1 is equipped with a support base connected to the maintenance platform 10. A support rod is connected below the support base, and the bottom end of the support rod has a base plate pre-embedded in the ground. This structure effectively improves the overall stability of the device, preventing tipping when the baking oven 5 is moved, thereby increasing the safety factor of the device.

[0057] This embodiment does not limit the specific structure of the baking device 5, as long as it can be connected to the top cover of the oven 20 and achieve the purpose of spraying flames into the oven 20 for baking. The lower end of the chain 61 is provided with four branch chains, which are respectively connected to four connecting posts at the edge of the baking device 5. The four connecting posts are evenly distributed along the circumference of the baking device 5 to ensure the stable connection of the baking device 5.

[0058] In some embodiments, the second beam 22 and the baking oven 5 may be connected by a method such as Figure 4 The structure shown. See also Figure 4 The outer end of the second beam 22 is also connected to a guide frame 23, and the guide frame 23 is provided with a guide cylinder 231 extending in the vertical direction; the baking oven 5 is connected to a lifting seat 51, and the lifting seat 51 is provided with a guide column 511 extending in the vertical direction, and the guide column 511 is slidably connected to the guide cylinder 231.

[0059] In this embodiment, the guide frame 23 is a rectangular plate fixedly connected to the bottom wall of the outer end of the second beam 22, and four guide cylinders 231 are provided, respectively located near the four corners of the guide frame 23. The lifting seat 51 is a rectangular seat bolted to the baking oven 5, and four guide columns 511 are also provided.

[0060] After connecting the oven 5 to the chain 61, the four guide posts 511 are inserted into the four guide cylinders 231 one by one. When the chain 61 lifting mechanism drives the oven 5 to rise and fall through the chain 61, the sliding cooperation between the guide posts 511 and the guide cylinders 231 ensures the stability of the oven 5 during the rising and falling process, and avoids it from shaking and generating unnecessary additional load.

[0061] In some embodiments, the chain lifting component 6 described above can be adopted as follows: Figure 2 and Figure 4 The structure shown. See also Figure 2 and Figure 4 The chain lifting assembly 6 includes a first driving member 62 and a guide wheel 63. The first driving member 62 is connected to the top wall of the second beam 22, and the chain 61 is connected to the extended end of the first driving member 62. The guide wheel 63 is rotatably connected to the outer end of the second beam 22. The guide wheel 63 has a guide groove on its peripheral wall, and the chain 61 slides in the guide groove.

[0062] In this embodiment, the first drive component 62 is in the form of a cylinder or an electric push rod. One end of the chain 61 is connected to the first drive component 62, and the other end passes over the guide wheel 63 and is connected to the oven 5, thus forming a closed-loop transmission. When the oven 5 needs to be lowered, the first drive component 62 is activated, its extended end extends, and under the action of the oven 5's own weight, it pulls the chain 61 to move downward. When the oven 5 needs to be raised, the extended end of the first drive component 62 retracts, and the chain 61 pulls the oven 5 upward.

[0063] In the above structure, the guide groove (usually a semi-circular groove or trapezoidal groove) on the peripheral wall of the guide wheel 63 slides and engages with the chain 61 to limit the lateral displacement of the chain 61 and ensure that the baker 5 rises and falls smoothly in the vertical direction. By combining the first drive component 62 with the flexible chain 61, compared with the traditional lifting structure formed by gear rack or lead screw, the vertical installation space is greatly saved, and no additional support structure is required. This meets the lightweight design requirements of the cantilever beam 2 and improves the convenience of later maintenance.

[0064] As a variation of the chain lifting component 6, see [link to relevant documentation]. Figure 2 The chain lifting assembly 6 also includes an extension rod 64, which extends along the extension direction of the second beam 22, and the two ends of the extension rod 64 are connected to the first drive member 62 and the chain 61, respectively.

[0065] In actual installation, in order to reduce the end load of the cantilever beam 2, the first drive component 62 needs to be set close to the inner end of the second beam 22. At this time, the length of the chain 61 needs to be increased along the length direction of the second beam 22. However, due to the flexible characteristics of the chain 61, if its length is too long, it is easy to sag, resulting in uncontrolled tension.

[0066] In this embodiment, an extension rod 64 is added between the first drive member 62 and the chain 61, which effectively avoids the above-mentioned problems. Specifically, two guide supports are provided on the top wall of the second beam 22 to support the extension rod 64 and guide its axial sliding. The first drive member 62 and the second beam 22 are connected by a hinge, and the extension rod 64 is also connected to the extended end of the first drive member 62 by a hinge. This simplifies the assembly process, eliminates the need to strictly ensure that the axes of the first drive member 62 and the extension rod 64 are perfectly aligned, and the hinge connection can buffer mechanical impacts to a certain extent, increasing the reliability of the device.

[0067] The extension rod 64, as an independent component, can be further configured as a telescopic structure to easily adapt to different sizes of ovens 5 or adjust the lifting stroke according to different sizes of ovens 20 without disassembling the corresponding parts.

[0068] In some embodiments, the telescopic drive component 4 described above may employ, for example... Figure 2 and Figure 7 The structure shown. See also Figure 2 and Figure 7 The telescopic drive assembly 4 includes a second drive member 41 and a hinged support 42; the second drive member 41 is hinged to the top wall of the first beam 21; the hinged support 42 is connected to the top wall of the second beam 22, and a rotating shaft 43 is connected to the hinged support 42. The main shaft of the rotating shaft 43 extends perpendicularly to the extension direction of the second beam 22, and the pushing end of the second drive member 41 is hinged to the rotating shaft 43.

[0069] The second driving component 41 pushes the rotating shaft 43, and then the hinged support 42 pushes the second beam 22 to extend outward along the first beam 21, thereby realizing the radial movement of the baking device 5.

[0070] The second driving component 41 is a cylinder or electric push rod, and is connected to the first beam 21 by a hinge, which allows the second driving component 41 to swing slightly in the vertical direction. The hinge support 42 can compensate for the height difference between the top wall of the second beam 22 and the axis of the pushing end of the second driving component 41, ensuring that the second driving component 41 applies a horizontal pushing force to the second beam 22. On the other hand, it forms a flexible node with the rotating shaft 43 and the pushing end of the second driving component 41. When the sliding of the second beam 22 is obstructed (such as by foreign objects), this flexible node allows the second driving component 41 to idle or swing briefly, avoiding damage to the components caused by rigid pushing.

[0071] The hinge between the second driving member 41 and the first beam 21, and the hinge between the pushing end of the second driving member 41 and the second beam 22, can also compensate for the installation error between the first beam 21 and the second beam 22, reduce the requirements for assembly accuracy, and help shorten the installation time.

[0072] In some embodiments, the first beam 21 may be adopted as follows: Figure 2 and Figure 5 The structure shown. See also Figure 2 and Figure 5 The first beam 21 includes a beam seat 211 and two C-shaped steel beams 212. The beam seat 211 is rotatably connected to the top of the column 1. The two C-shaped steel beams 212 are respectively connected to the side wall of the beam seat 211, and the openings of the two C-shaped steel beams 212 are arranged opposite to each other. The second beam 22 is slidably connected between the two C-shaped steel beams 212.

[0073] In this embodiment, the first beam 21 is configured as a combination of a beam seat 211 and two C-shaped steel beams 212. This structure can both contain the second beam 22 through the C-shaped steel beams 212 with their openings facing each other and provide a horizontal extension limit track for it, and also help to reduce the cross-sectional size of the first beam 21, thereby reducing the overall weight of the cantilever beam 2 and saving the cost of steel materials.

[0074] In some embodiments, the second beam 22 and the first beam 21 may be connected by, for example, Figure 2 , Figure 5 and Figure 7 The structure shown. See also Figure 2 , Figure 5 and Figure 7 A roller assembly 7 is provided between the second beam 22 and the first beam 21. The roller assembly 7 includes a first roller 71 and a second roller 72. The first roller 71 is rotatably connected to the outer wall of the second beam 22, and its main shaft extends in the vertical direction. The first roller 71 rolls with the inner wall of the C-shaped steel beam 212. The second roller 72 is rotatably connected to the outer wall of the second beam 22, and its main shaft extends in the horizontal direction. The second roller 72 rolls with the inner bottom wall of the C-shaped steel beam 212.

[0075] In this embodiment, the portion of the first beam 21 used to accommodate the second beam 22 is set as two C-shaped steel beams 212 with opposite openings. The roller group 7 is used to support and guide the second beam 22, which simplifies the overall structure and improves the performance of the cantilever beam 2.

[0076] Specifically, the second beam 22 is a rectangular tubular structure with a rectangular internal cavity and a flat outer wall. The first roller 71 is rotatably connected to the second beam 22 via a combination of two support plates and a pin, and is used for rolling engagement with the inner wall of the C-shaped steel beam 212, limiting the lateral displacement of the second beam 22. The second roller 72 is rotatably connected to the second beam 22 via a bolt and nut assembly, and is used for rolling engagement with the inner bottom wall of the C-shaped steel beam 212, supporting the second beam 22 and restraining its vertical sway. The combination of the first roller 71 and the second roller 72 achieves backlash-free rolling guidance of the second beam 22, improving guidance accuracy.

[0077] It should be noted that the second beam 22 has two outer side walls, left and right. Each outer side wall is provided with multiple first rollers 71 and second rollers 72 at intervals. The multiple first rollers 71 / second rollers 72 on the left and right outer side walls are arranged in a one-to-one correspondence to ensure that the second beam 22 is subjected to balanced force and can stably extend and retract.

[0078] In addition, the arrangement of the first roller 71 and the second roller 72 creates rolling friction between the second beam 22 and the first beam 21, which helps to reduce the extension and retraction driving force of the second beam 22 and can be adapted to a smaller second drive component 41, thereby reducing energy consumption and equipment cost.

[0079] In some embodiments, the rotary drive component 3 described above may employ, for example... Figure 2 and Figure 3 The structure shown. See also Figure 2 and Figure 3 The rotary drive assembly 3 includes a third drive member 31, a drive gear 32, and a driven gear 33. The third drive member 31 is connected to the lower part of the first beam 21 and has a downwardly extending drive end. The drive gear 32 is sleeved on the outer periphery of the drive end. The driven gear 33 is sleeved on the outer periphery of the column 1, and the drive gear 32 meshes with the driven gear 33.

[0080] In this embodiment, the third driving component 31 adopts a combination structure of motor reducer and is connected to the lower part of the first beam 21 through the mounting base 34. The mounting base 34 is connected to the bottom wall of the first beam 21 and extends downward. The third driving component 31 is installed on the mounting base 34 in the vertical direction. The driving gear 32 is connected to the driving end of the third driving component 31, and the driven gear 33 is fixedly sleeved on the outer periphery of the column 1.

[0081] The third driving member 31 drives the driving gear 32 to rotate. The meshing action of the driving gear 32 and the driven gear 33 causes the driving gear 32 and the third driving member 31 to rotate around the axis of the column 1. On this basis, the beam seat 211 of the first beam 21 is rotatably connected to the column 1 through the bearing, thereby realizing the horizontal swing of the first beam 21.

[0082] The above structure is simple and compact, which can effectively reduce space utilization and facilitate precise control of the horizontal swing angle of the oven 5.

[0083] In some embodiments, see Figures 3 to 5 A baking device for an oven also includes a gas pipeline 8, which includes a first pipe section 82 and a second pipe section 83. The first pipe section 82 is laid on the outer wall of the column 1 and extends upward; the second pipe section 83 is located in the internal cavity of the cantilever beam 2 and extends along the extension direction of the cantilever beam 2; wherein, the first pipe section 82 is connected to the gas source, the extended end of the second pipe section 83 is connected to the top of the baking device 5, and the first pipe section 82 and the second pipe section 83 are connected by a first flexible section 81.

[0084] The first pipe section 82 is laid on the outer wall of the column 1 using pipe clamps. The rigidity of the column 1 serves as support, preventing pipe vibration caused by suspended installation and avoiding positional interference with other equipment. The second pipe section 83 is hidden in the internal cavity of the cantilever beam 2, without occupying external space. It is also able to isolate the high-temperature ring between the cantilever beam 2 and the furnace 20 below, preventing the high temperature from adversely affecting the gas pipeline 8.

[0085] The first flexible section 81 can be configured as a metal corrugated pipe structure and connected to the first pipe section 82 and the second pipe section 83 respectively through flanges. The first flexible section 81 can absorb the displacement of the gas pipeline 8 caused by the angle change when the cantilever beam 2 swings horizontally, avoid the problem of mutual interference between the connection of the gas pipeline 8 and the swing of the cantilever beam 2, and ensure the continuity of gas transmission.

[0086] It should be noted that the second pipe section 83 enters the interior of the second beam 22 through the cavity between the two C-shaped steel beams 212, and the second pipe section 83 itself is also provided with a flexible section, the length of which is greater than the maximum length of the cantilever beam 2, so as to meet the gas supply when the second beam 22 is extended.

[0087] In some embodiments, a baking apparatus for an oven further includes an air duct 9, which includes a third pipe section 92 and a fourth pipe section 93. The third pipe section 92 is located in the internal cavity of the column 1 and extends upward; the fourth pipe section 93 is located in the internal cavity of the cantilever beam 2 and extends along the extension direction of the cantilever beam 2. The third pipe section 92 is connected to a fan, and the extended end of the fourth pipe section 93 is connected to the baking device 5. The third pipe section 92 and the fourth pipe section 93 are connected by a second flexible section 91.

[0088] The diameter of the air pipe 9 is larger than that of the gas pipe 8, making it inconvenient to lay along the outer wall of the column 1. In this embodiment, the column 1 is a cylindrical component, and the third pipe section 92 is placed in the internal cavity of the column 1, which effectively saves external space and ensures the overall neatness of the device.

[0089] The design concept of the second flexible segment 91 is the same as that of the first flexible segment 81, both designed to accommodate the horizontal swing of the cantilever beam 2.

[0090] The fourth pipe section 93 is installed in the same way as the second pipe section 83, also within the internal cavity of the cantilever beam 2, and has a flexible section to accommodate the expansion and contraction of the cantilever beam 2. Similarly, when the cross-sectional dimensions of the cantilever beam 2 are relatively small, the second pipe section 83 and the fourth pipe section 93 can be laid at the bottom of the cantilever beam 2. Furthermore, by covering the second beam body 22 with a protective cover, the second pipe section 83 and the fourth pipe section 93 are isolated from the high-temperature environment of the furnace 20, effectively protecting the safety of the pipeline.

[0091] Gas line 8 and air line 9 provide reliable gas and air sources for baker 5, ensuring continuous baking operation of baker 5.

[0092] 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.
