Description

Technical Field

[0001] The utility model relates to the technical field of kiln structures, in particular to an installation structure of kiln rollers and a kiln. Background Art

[0002] Kiln rollers are typically supported by rollers (bearings). Due to long-term high-temperature operation, the rollers can wear and the fixing bolts can become stuck, causing the rollers to climb and break, necessitating replacement. In existing technology, the rollers (bearings) are bolted directly to the support plate. When replacing the rollers (bearings), the mating threads of the bolts and screw holes can become necrotic due to long-term thermal expansion and contraction. During disassembly, the bolts can easily break in the screw holes of the support plate, increasing the workload. Furthermore, replacement typically occurs during the dry-burn period, when the furnace temperature is very high, making the work difficult and posing a risk of burns. Utility Model Content

[0045] Combine Figures 1-8An embodiment of the utility model provides an installation structure of a kiln roller, which is used for rolling support of a kiln roller 100. The installation structure of the kiln roller includes a support plate 1, a bracket 2 and a supporting roller 3. The bracket 2 is clamped with the support plate 1. There are multiple supporting rollers 3. The multiple supporting rollers 3 are rotatably installed on the bracket 2, and the kiln roller 100 is rollingly supported on the multiple supporting rollers 3.

[0046] The utility model provides a kiln roller installation structure, such as Figure 1-Figure 3 The conveying direction of the kiln roller 100 is along the X direction, the length direction of the kiln roller 100 is along the Y direction, and the supporting wheel 3 is arranged below the kiln roller 100 along the Z direction for rolling support of the kiln roller 100. The X direction, Y direction, and Z direction are perpendicular to each other. In this embodiment, by providing a bracket 2, the supporting wheel 3 is pre-rotated and installed on the bracket 2 to form an assembly. The bracket 2 is clamped with the support plate 1, avoiding the threaded connection between the supporting wheel 3 and the support plate 1. The bracket 2 and the support plate 1 do not require additional parts for assembly and disassembly, making it easy to assemble and disassemble. This simplifies the installation structure of the kiln roller and solves the problem of the supporting wheel 3 of the kiln roller 100 being difficult to assemble and disassemble, which is conducive to improving the efficiency of disassembly of the supporting wheel 3. Compared with the prior art in which the supporting wheel 3 needs to be removed by removing bolts for disassembly, the supporting wheel 3 can be disassembled at room temperature, avoiding the safety risks caused by high-temperature disassembly.

[0047] In some embodiments, there are multiple brackets 2, and multiple supporting wheels 3 are installed on the multiple brackets 2 one by one. The multiple brackets 2 are arranged on the support plate 1 at intervals along the conveying direction of the kiln rollers 100 so that the multiple supporting wheels 3 roll and support the multiple kiln rollers 100 in sequence.

[0048] like Figure 3-Figure 5 As shown, multiple brackets 2 and multiple supporting rollers 3 are arranged in a one-to-one correspondence, and a kiln roller 100 is rollingly supported between any two adjacent supporting rollers 3. By setting multiple brackets 2, each supporting roller 3 can be individually mounted on the support plate 1 through a bracket 2, which facilitates individual disassembly and replacement of a single supporting roller 3 when a defect occurs, thereby reducing the difficulty of disassembly.

[0049] In some embodiments, the bracket 2 is provided with a mounting groove 21 , and the mounting groove 21 is buckled on the support plate 1 and fixedly connected to the support plate 1 .

[0050] like Figure 4-Figure 6 As shown, the mounting groove 21 on the bracket 2 is provided through the X-direction, and the two side walls of the mounting groove 21 along the Y-direction are buckled with the support plate 1 and snap-fitted to the support plate 1, facilitating installation and removal. The snap-fit ​​method allows installation without bolts or screws, which helps improve assembly and disassembly efficiency.

[0051] In some embodiments, along the length direction of the kiln roller 100 , the inner wall of the mounting groove 21 abuts against the outer wall of the support plate 1 .

[0052] For example Figure 4-Figure 6 Along the Y direction, the inner walls on both sides of the mounting groove 21 can abut against the outer walls on both sides of the support plate 1, thereby realizing the Y-direction limitation of the bracket 2, which is beneficial to ensure the consistency of the positions of multiple brackets 2 or supporting wheels 3 on the same support plate 1 in the X direction, thereby achieving balanced support for the kiln roller 100 and ensuring the accuracy of the conveying direction of the kiln roller 100.

[0053] In some embodiments, a limiting portion 111 is provided on the support plate 1 , and the bracket 2 can stop at the limiting portion 111 along the conveying direction of the kiln roller 100 .

[0054] like Figure 4 and Figure 5 As shown, the limiting portion 111 abuts against the bracket 2 along the X direction to limit the bracket 2 in the X direction, so that the spacing between multiple brackets 2 is fixed, thereby ensuring that the spacing between multiple supporting wheels 3 is fixed, and achieving stable and balanced rolling support for the kiln roller 100.

[0055] In some embodiments, there are multiple limiting portions 111 , which are spaced apart along the conveying direction of the kiln roller 100 , and both sides of the bracket 2 along the conveying direction of the kiln roller 100 respectively stop at one limiting portion 111 .

[0056] like Figure 4 and Figure 5 The bracket 2 is buckled with the support plate 1 from top to bottom along the Z direction, and the two sides of the bracket 2 along the X direction are respectively abutted against the two limit parts 111, and the two sides of the bracket 2 along the Y direction are respectively abutted against the outer wall of the support plate 1, and the kiln roller 100 is pressed onto the supporting wheel 3. Under the action of the gravity of the kiln roller 100, a reliable clamping is achieved between the bracket 2 and the support plate 1.

[0057] In some embodiments, a plurality of limiting grooves 11 are provided on the support plate 1, and the two side walls of the limiting groove 11 along the conveying direction of the kiln roller 100 form two limiting portions 111, and the bracket 2 is inserted into the limiting groove 11 and abuts against the two side walls of the limiting groove 11.

[0058] like Figure 5 Along the X-direction, multiple limiting slots 11 are spaced apart on the support plate 1. Each limiting slot 11 is provided through the Y-direction. The mounting slot 21 of the bracket 2 is inserted into the support plate 1 at the limiting slot 11 to achieve a snap connection. The two ends of the mounting slot 21 along the X-direction abut the two side walls of the limiting slot 11, and the two inner walls of the mounting slot 21 along the Y-direction abut the two outer walls of the support plate 1 along the Y-direction, achieving a snap connection between the bracket 2 and the support plate 1. During use, the weight of the kiln roller 100 is transmitted to the bracket 2 via the supporting roller 3, ensuring that the bracket 2 is securely connected to the support plate 1 below. When the supporting roller 3 needs to be removed, the bracket 2 is simply lifted up and separated from the support plate 1.

[0059] In some embodiments, a limiting block 12 is provided in the limiting groove 11 , and the mounting groove 21 of the bracket 2 is buckled on the limiting block 12 .

[0060] like Figure 7 and Figure 8 As shown, a limit block 12 is provided in the limit groove 11. The size of the limit block 12 along the Y direction is equal to the size of the support plate 1. The mounting groove 21 of the bracket 2 is buckled onto the limit block 12, and the inner walls of the mounting groove 21 along the Y direction abut against the outer walls of the limit block 12, thereby limiting the Y direction of the bracket 2. When the bracket 2 is inserted into the support plate 1, the limit block 12 is located in the mounting groove 21, thereby increasing the structural strength of the bracket 2 and improving the stability and reliability of the supporting roller 3.

[0061] In some embodiments, along the conveying direction of the kiln roller 100 , both sides of the limiting block 12 are fixedly abutted against the groove walls of the limiting groove 11 .

[0062] like Figure 8 As described, the two sides of the limit block 12 along the X direction abut against the two side walls of the limit groove 11 to fill the limit groove 11. Furthermore, the two sides of the limit block 12 can be welded and fixed to the side walls of the limit groove 11, or clamped to the side walls of the limit groove 11. For example, a slider and a slide groove assembly can be set between the side walls of the limit groove 11 and the side walls of the limit block 12, so that the limit block 12 can be slidably installed in the limit groove 11 along the Z direction, for limiting and fixing the bracket 2.

[0063] In some embodiments, the limit block 12 and the support plate 1 are an integral structure. Figure 8 In the embodiment in which the limit block 12 and the support plate 1 are an integrated structure, the top of the limit block 12 is the bottom of the limit groove 11, and the mounting groove 21 is buckled on the limit block 12. The bottom of the mounting groove 21 abuts against the top of the limit block 12 for limiting positioning. The inner walls on both sides of the mounting groove 21 along the Y direction fit and abut against the limit block 12, and the two ends of the mounting groove 21 along the X direction abut against the groove walls on both sides of the limit groove 11 (i.e., the limiting portion 111), thereby realizing the clamping and fixing of the bracket 2 and the support plate 1.

[0064] In some embodiments, the bracket 2 includes a top plate 22 and two side plates 23 . The two side plates 23 are spaced apart on both sides of the top plate 22 and are parallel to each other to form a mounting groove 21 . The supporting wheel 3 is rotatably mounted on the side plates 23 .

[0065] like Figure 6As shown, the top plate 22 and two side plates 23 enclose a U-shaped mounting groove 21. The bottom and walls of the mounting groove 21 are flat, facilitating positional mounting with the support plate 1 or the stop block 12. In a preferred embodiment, the bracket 2 is a one-piece structure, which is easy to process and has high structural strength. One supporting roller 3 is rotatably mounted on any one of the side plates 23, or two supporting rollers 3 are simultaneously rotatably mounted on both side plates 23. When two supporting rollers 3 are mounted on a single bracket 2, the two supporting rollers 3 are symmetrically mounted on either side of the bracket 2 along the Y direction.

[0066] In some embodiments, a connecting shaft 4 is fixedly provided on the side plate 23 , and the connecting shaft 4 is provided perpendicular to the side plate 23 . The supporting wheel 3 is connected to the connecting shaft 4 via a rolling bearing 31 .

[0067] For example Figure 6 A connecting shaft 4 is vertically disposed on one side plate 23 of the bracket 2 for rotatably mounting the supporting roller 3. The connecting shaft 4 and the side plate 23 may be integrally formed. The supporting roller 3 is connected to the connecting shaft 4 via a rolling bearing 31. The connecting shaft 4 is disposed along the Y direction. Of course, in other embodiments, connecting shafts 4 may be disposed on each of the two side plates 23 of the bracket 2 for symmetrically mounting two supporting rollers 3, thereby achieving multi-point support for the kiln roller 100 and improving stability.

[0068] In some embodiments, a set distance L is provided between the top of the limiting block 12 and the top of the limiting groove 11 , and the set distance L is equal to the thickness of the top plate 22 .

[0069] like Figure 5 and Figure 8 As shown, when the mounting groove 21 is buckled above the limit block 12, the bottom of the mounting groove 21 is in contact with the top of the limit block 12, and the set distance L is equal to the thickness of the top plate 22, so that the bracket 2 is flush with the upper surface of the support plate 1 after being snapped onto the support plate 1, forming a Figure 5 The upper surface shown thereby realizes the Z-direction positioning of the bracket 2 or the supporting wheel 3, which is beneficial to the consistent installation and positioning of multiple supporting wheels 3.

[0070] In some embodiments, the support plate 1 is extended along the conveying direction of the kiln roller 100 , and at least two support plates 1 are provided. The at least two support plates 1 are spaced apart along the length direction of the kiln roller 100 .

[0071] like Figure 4 As shown, two support plates 1 are provided as an example. The two support plates 1 are spaced apart in the Y direction to support two rows of kiln rollers 100. The length of the support plates 1 in the X direction is greater than the arrangement length of the multiple kiln rollers 100. Any two adjacent supporting wheels 3 rollingly support one kiln roller 100, reducing the friction on the kiln rollers 100.

[0072] In some embodiments, the limiting grooves 11 are evenly spaced along the length direction of the support plate 1 , thereby achieving uniform supporting force for the kiln roller 100 .

[0073] The present invention also provides a kiln, including a kiln roller mounting structure provided by the present invention. The kiln roller 100 of the kiln is rollingly supported on a supporting roller 3, which is rotatably mounted on a bracket 2, which is engaged with a support plate 1. The kiln provided by the present invention pre-assembles the supporting roller 3 on the bracket 2 and allows the supporting roller 3 to be mounted by engaging the bracket 2 with the support plate 1. This improves the efficiency of installing and removing the supporting roller 3 and greatly enhances safety during replacement of the supporting roller 3.

[0074] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
