Description

Technical Field

[0001] This utility model relates to the field of support device technology, specifically a furnace roller support device. Background Technology

[0002] Furnace rollers are key components in industrial furnaces, primarily used to support and transport materials through the heating zone, ensuring uniform heating and stable transport of materials in a high-temperature environment. They are typically made of high-temperature resistant alloy steel or ceramic materials to withstand extreme temperatures and thermal stresses within the furnace, while also possessing oxidation resistance, corrosion resistance, and wear resistance to extend their service life. The surface of the furnace rollers is precision-machined to reduce friction with the materials, prevent scratches or deformation, and ensure product surface quality. Furnace rollers are divided into active rollers and passive rollers. The active rollers are driven by a motor to move the materials forward, while the passive rollers rotate with the material. The two work together to ensure continuous production. In industries such as metallurgy, glass, and ceramics, the performance of furnace rollers directly affects heating efficiency and finished product quality. Therefore, regular maintenance and lubrication are necessary to prevent oxide scale buildup or bearing damage. With technological advancements, furnace rollers are gradually developing towards lightweight, high-precision, and intelligent designs to meet the demands of high-efficiency and energy-saving production.

However, in the existing technology, if the furnace roller support device lacks effective buffering when the equipment is started up or stopped or the load fluctuates, the furnace roller may be subjected to instantaneous impact force, affecting the overall service life. Therefore, we need a furnace roller support device. Utility Model Content

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] This utility model embodiment provides a furnace roller support device, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the system includes a base 1, a lifting assembly 2 inside the base 1, a support shell 3 fixedly connected to the top of the base 1, a buffer assembly 4 on the top of the support shell 3, a telescopic block 5 on the top of the buffer assembly 4, a support platform 6 fixedly connected to the top of the telescopic block 5, a rotating roller 7 rotatably connected to one side of the support platform 6, the buffer assembly 4 includes a buffer shell 401, and the buffer shell 401 is located on top of the support shell 3, an installation block 402 fixedly connected inside the buffer shell 401, a guide rod 403 fixedly connected to one side of the installation block 402, a buffer spring 404 sleeved on the outer wall of the guide rod 403, a moving rod 405 hinged to the top of the installation block 402, a support rod 406 hinged to the outer wall of the moving rod 405, a sliding sleeve 407 hinged to one end of the support rod 406, a cylindrical sleeve 408 fixedly connected inside the buffer shell 401, a support spring 409 fixedly connected inside the cylindrical sleeve 408, and a support column 410 fixedly connected to one end of the support spring 409.

[0018] Furthermore, such as Figure 4 As shown, the sliding sleeve 407 forms a support structure with the moving rod 405 via the support rod 406. One end of the support rod 406 is hinged to the top of the sliding sleeve 407, and the other end of the support rod 406 is hinged to the outer wall of the moving rod 405. This allows the support rod 406 to push the moving rod 405 to move when the sliding sleeve 407 moves, thereby improving the support effect of the sliding sleeve 407 on the moving rod 405.

[0019] Furthermore, such as Figure 5 As shown, the cylindrical sleeve 408 forms an elastic structure with the support column 410 through the support spring 409. One end of the support spring 409 is fixedly connected to the inside of the cylindrical sleeve 408, and the other end of the support spring 409 is fixedly connected to one end of the support column 410. With the support spring 409, the support spring 409 can support the support column 410 with the support of the cylindrical sleeve 408, thereby improving the support effect of the cylindrical sleeve 408 on the support column 410.

[0020] In a further preferred embodiment of this utility model, such as Figure 1 , Figure 2 and Figure 3As shown, the lifting assembly 2 includes a fixed block 201, which is fixedly connected to the inside of the base 1. A motor 202 is provided on the top of the fixed block 201. The output end of the motor 202 is fixedly connected to a drive bevel gear 203 via a coupling. A transmission bevel gear 204 is meshed with the outer wall of the drive bevel gear 203. A rotating rod 205 is fixedly connected to the inner wall of the transmission bevel gear 204. A first support block 206 is rotatably connected to the outer wall of the rotating rod 205. The bottom of the first support block 206 is fixedly connected to the inside of the base 1. A first bevel gear 207 is fixedly connected to the outer wall of the rotating rod 205. A second bevel gear 208 is meshed with the outer wall of the first bevel gear 207. A screw 209 is fixedly connected to the inner wall of the second bevel gear 208. A second support block 210 is rotatably connected to the outer wall of the screw 209. One side of the second support block 210 is fixed inside the support shell 3. A movable sleeve 211 is threadedly connected to the outer wall of the screw 209.

[0021] Furthermore, such as Figure 3 As shown, the motor 202 forms a rotating structure through the drive bevel gear 203 and the transmission bevel gear 204. The outer wall of the drive bevel gear 203 meshes with the outer wall of the transmission bevel gear 204. The drive bevel gear 203 and the transmission bevel gear 204 are arranged perpendicularly, so that when the motor 202 drives the drive bevel gear 203 to rotate, the drive bevel gear 203 drives the transmission bevel gear 204 to rotate.

[0022] Furthermore, such as Figure 3 As shown, the rotating rod 205 forms a linkage structure with the first bevel gear 207 and the second bevel gear 208. The inner wall of the first bevel gear 207 is fixedly connected to the outer wall of the rotating rod 205, and the outer wall of the first bevel gear 207 is meshed with the outer wall of the second bevel gear 208. This allows the rotating rod 205 to drive the first bevel gear 207 to rotate, which in turn drives the second bevel gear 208 to rotate.

[0023] Furthermore, such as Figure 2 and Figure 3 As shown, the second bevel gear 208 forms a movable structure with the screw 209 and the movable sleeve 211. The outer wall of the screw 209 is fixedly connected to the inner wall of the second bevel gear 208, and the outer wall of the screw 209 is threadedly connected to the inner wall of the movable sleeve 211. This allows the screw 209 to move when the second bevel gear 208 drives the screw 209 to rotate.

[0024] Working principle: During operation, if the equipment starts or stops or the load fluctuates, the rotating roller 7 will move downwards. The rotating roller 7 drives the support platform 6 to move, and the support platform 6 drives the telescopic block 5 to move along the inner wall of the buffer shell 401. At this time, the telescopic block 5 pushes the moving rod 405 to move, and the moving rod 405 pushes the support rod 406 to move, so that the support rod 406 pushes the sliding sleeve 407 to move along the outer wall of the guide rod 403. This causes the sliding sleeve 407 to compress the buffer spring 404 and retract, completing part of the buffering. At the same time, the telescopic block 5 compresses the support column 410 to move along the inner wall of the cylindrical sleeve 408, so that the support column 410 compresses the support spring 409 and retracts, completing the buffering and preventing the furnace roller from being affected by instantaneous impact forces. For overall service life, if the height of the rotating roller 7 needs to be adjusted, the motor 202 can be started to drive the drive bevel gear 203 to rotate, the drive bevel gear 203 drives the transmission bevel gear 204 to rotate, the transmission bevel gear 204 drives the rotating rod 205 to rotate on the inner wall of the first support block 206, the rotating rod 205 drives the first bevel gear 207 to rotate, the first bevel gear 207 drives the second bevel gear 208 to rotate, the second bevel gear 208 drives the screw 209 to rotate on the inner wall of the second support block 210, and at the same time the screw 209 rotates on the inner wall of the movable sleeve 211, thereby causing the movable sleeve 211 to drive the rotating roller 7 to rise and fall, which can adapt to different working conditions and optimize the material conveying in the furnace.

[0025] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
