Description

Technical Field

[0001] This utility model relates to the field of accessories technology for ring coolers, specifically to a rotary arm type ring cooler fine-tuning support roller. Background Technology

[0002] The rotary arm type liquid-sealed annular cooler (hereinafter referred to as the annular cooler) is the main main equipment for ironmaking processes (sintering, pelletizing) in the current iron and steel metallurgical industry. As a large-scale system that must be assembled and debugged on-site, the quality of on-site installation has a crucial impact on the equipment's performance and lifespan. When the annular cooler is working, the hot ore is supported by a rotating frame trolley with circular motion, and heat exchange occurs. At this time, the support rail on the underside of the rotating frame trolley and the support rollers move relative to each other. The support rollers consist of rollers and roller seats. These two parts are assembled as a whole at the factory. After arriving at the site, they are connected and installed with the base attached to the frame of the annular cooler to form the complete circular motion support of the annular cooler.

[0003] From the appendix Figure 1 As can be seen from the principles of motion geometry, the radius R of the support rail is the theoretical running trajectory of the rotating frame trolley of the ring cooler. Therefore, the installation accuracy requirement of the support rollers (the roller axis passing through the center of the ring cooler) is a core technical point for the operation of the ring cooler and is crucial to its operating characteristics. (See attached...) Figure 1 As shown in the dashed box, if the rollers are not installed correctly (the axis deviates from the center of the ring cooler), the rotating frame trolley will inevitably experience a deviating force from the theoretical running tangential direction shown in the diagram. This will cause the ring cooler to run off-center, often resulting in a series of adverse effects such as derailment, support roller jumping / abnormal noise, and accelerated wear of the track / rollers. This significantly affects the service life of the equipment and increases maintenance costs. Therefore, when installing the support rollers, if... Figure 1 Adjusting the roller position along the radial direction R of the annular cooler (position accuracy ±1mm) to ensure that the roller axis coincides with the center of the annular cooler is an indispensable and crucial step. However, in practice, due to the weight of the support rollers (up to 600kg each), the conventional adjustment method of striking with a hammer is insufficient to achieve the required level of precision.

[0004] In summary, there is an urgent need for a rotary arm type ring cooler with fine-tuning support rollers to solve or at least partially solve the problems existing in the prior art. Utility Model Content

[0028] To facilitate understanding of this invention, a more comprehensive description is provided below, along with preferred embodiments. However, this invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this invention.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0030] Example:

[0031] See Figures 2-7 This embodiment provides a fine-tuning support roller for a rotary arm type ring cooler, including a roller 1, a roller seat 2, a base 3, and an adjustment mechanism 4; the roller 1 is rotatably connected to the roller seat 2, and the roller seat 2 is detachably connected to the base 3; the first end of the adjustment mechanism 4 is connected to the base 3, and the second end of the adjustment mechanism 4 is connected to the roller seat 2; the adjustment mechanism 4 includes an adjustment seat 41 and an adjustment rod 42 for adjusting the relative distance between the adjustment seat 41 and the roller seat 2, the adjustment seat 41 is mounted on the base 3, the first end of the adjustment rod 42 is connected to the adjustment seat 41, and the second end of the adjustment rod 42 is connected to the roller seat 2.

[0032] It should be noted that the base 3 is installed on the frame of the annular cooler, or the base 3 is integrated with the frame of the annular cooler.

[0033] It can be seen that the relative distance between the adjusting seat 41 and the roller seat 2 is adjusted by adjusting the adjusting rod 42. Since the roller seat 2 is stationary relative to the base 3, the relative position between the roller seat 2 and the base 3 is changed by adjusting the adjusting rod 42, thereby changing the relative position between the roller 1 and the base 3. The adjustment process is carried out by adjusting the adjusting rod 42, which is convenient for adjustment and has higher adjustment accuracy than the adjustment method of using a hammer to strike. It improves the adjustment accuracy while reducing the adjustment difficulty.

[0034] In a preferred embodiment of this application, the base 3 is provided with a positioning hole 31, and the roller seat 2 is provided with a through hole 21. The through hole 21 is arranged correspondingly to the positioning hole 31, and the diameter of the through hole 21 is larger than the diameter of the positioning hole 31. A positioning rod 411 extends downward from the adjusting seat 41. The positioning rod 411 passes through the through hole 21 from top to bottom and is coaxially inserted in the positioning hole 31. The outer side wall of the positioning rod 411 is arranged to abut against the inner side wall of the positioning hole 31. A clearance is left between the positioning rod 411 and the through hole 21, so that the roller seat 2 can move relative to the base 3 and the adjusting seat 41 during the adjustment process, and the roller seat 2 will not interfere with the positioning rod 411 during the movement. At the same time, because the outer side wall of the positioning rod 411 is arranged to abut against the inner side wall of the positioning hole 31 during the adjustment process, the positioning rod 411 is always limited in the positioning hole 31 on the base 3 during the adjustment process. The adjusting rod 42 includes a screw 421, a first nut 422, a second nut 423, and an adjusting nut 427. The screw 421 is arranged horizontally through the adjusting seat 41. The adjusting nut 427 is threaded onto the screw 421 and abuts against the side wall of the adjusting seat 41. The roller seat 2 is provided with an adjusting hole 22. The screw 421 is arranged through the adjusting hole 22. The first nut 422 and the second nut 423 are both threaded onto the screw 421. The first nut 422 is arranged at the end of the adjusting hole 22 away from the adjusting seat 41, and the second nut 423 is arranged at the end of the adjusting hole 22 close to the adjusting seat 41. The screw 421 is fixedly connected to the roller seat 2 by the arrangement of the first nut 422 and the second nut 423.

[0035] It should be noted that when the adjusting nut 427 is positioned on the side of the adjusting seat 41 away from the roller seat 2, rotating the adjusting nut 427 applies a pulling force to the roller seat 2, causing the roller seat 2 to move towards the adjusting seat 41, thus adjusting the position of the roller seat 2 relative to the base 3. When the adjusting nut 427 is positioned on the side of the adjusting seat 41 close to the roller seat 2, rotating the adjusting nut 427 applies a pushing force to the roller seat 2, causing the roller seat 2 to move away from the adjusting seat 41, thus adjusting the position of the roller seat 2 relative to the base 3.

[0036] It can be understood that, through the above-mentioned arrangement, the positioning rod 411 passes through the through hole 21 from top to bottom and is inserted and fixed in the positioning hole 31, so that the positioning rod 411 and the adjusting seat 41 are limited to the base 3. Even if the positioning rod 411 and the adjusting seat 41 can only rotate around the axis of the positioning rod 411 on the base 3, the positioning rod 411 and the adjusting seat 41 are restricted from moving horizontally relative to the base 3.

[0037] Thus, when adjusting the adjusting rod 42, the distance between the roller seat 2 and the adjusting seat 41 is changed, that is, the relative distance between the roller seat 2 and the base 3 is changed, thereby realizing the adjustment of the position of the roller seat 2 relative to the base 3, and further realizing the adjustment of the position of the roller 1 relative to the base 3.

[0038] Furthermore, two sets of adjustment mechanisms 4 are provided, and the two sets of adjustment mechanisms 4 are respectively arranged on the sides of both ends of the roller seat 2. Specifically, the rotary frame trolley 7 supported on the support roller is annular. During adjustment, one set of adjustment mechanisms 4 moves the first end of the roller seat 2 closer to or further away from the center of the rotary frame trolley 7, while keeping the second end of the roller seat 2 stationary, thereby changing the direction of the roller seat 2 and the roller 1, so that the roller 1 rolls along the circular tangent direction of the rotary frame trolley 7; or by using the other set of adjustment mechanisms 4 to move the second end of the roller seat 2 away from or closer to the center of the rotary frame trolley 7, while keeping the first end of the roller seat 2 stationary, the direction of the roller seat 2 and the roller 1 can also be changed, so that the roller 1 rolls along the circular tangent direction of the rotary frame trolley 7.

[0039] It is understood that by moving one end of the roller seat 2 closer to or further away from the center of the rotary frame trolley 7, the position and angle of the roller 1 can be adjusted, causing the roller 1 to roll along the tangent of the arc of the rotary frame trolley 7, thereby reducing friction and preventing the rotary frame trolley 7 from derailing. Two sets of adjustment mechanisms 4 are used to adjust both ends of the roller seat 2 respectively. During adjustment, the angle of the roller 1 can be adjusted by adjusting the adjustment mechanism 4 at either end of the roller seat 2, facilitating the adjustment of the roller 1.

[0040] Furthermore, the adjusting rod 42 also includes a first pad 424 and a second pad 425. A screw 421 passes through the first pad 424 and the second pad 425. The first pad 424 and the second pad 425 are respectively arranged at both ends of the adjusting hole 22, and the first pad 424 and the second pad 425 are clamped on the roller seat 2 by the first nut 422 and the second nut 423.

[0041] It is known that the first pad 424 and the second pad 425 serve as pads to prevent the first nut 422 and the second nut 423 from being embedded in the adjustment hole 22, which would prevent the first nut 422 and the second nut 423 from being rotated in the future.

[0042] Furthermore, the adjusting rod 42 also includes a locking nut 426, which is threaded onto the screw 421, and one side of the locking nut 426 abuts against the adjusting seat 41. Specifically, the locking nut 426 and the adjusting nut 427 are respectively arranged on both sides of the adjusting seat 41. When the locking nut 426 is tightened, the locking nut 426 and the adjusting nut 427 clamp the adjusting seat 41.

[0043] It can be understood that by loosening the locking nut 426, the adjusting nut 427 can be smoothly rotated to adjust the relative position of the roller seat 2. When locking is required, the locking nut 426 is tightened. At this time, the locking nut 426 and the adjusting nut 427 are clamped on both sides of the adjusting seat 41. The friction prevents the adjusting nut 427 from rotating, thus achieving the purpose of locking. When unlocking is required, the locking nut 426 is rotated to separate the locking nut 426 from the adjusting seat 41. At this time, the adjusting nut 427 can be smoothly rotated to complete the unlocking. It should also be noted that in this embodiment, the locking nut 426 and the adjusting nut 427 can be interchanged. After the interchange, the adjusting mechanism 4 changes from applying a pulling force to the roller seat 2 to applying a pushing force to the roller seat 2, or from applying a pushing force to the roller seat 2 to applying a pulling force to the roller seat 2.

[0044] Furthermore, the roller seat 2 includes a base plate 23 and two vertical plates 24. The two vertical plates 24 are arranged parallel to each other and vertically on the base plate 23. The through hole 21 is arranged on the base plate 23 and located at the edge of the base plate 23. The adjustment hole 22 is arranged on one of the vertical plates 24. The roller 1 is arranged between the two vertical plates 24 and is simultaneously rotatably connected to the two vertical plates 24. The axis of the roller 1 is arranged horizontally.

[0045] Specifically, the two upright plates 24 are fixedly connected to the base plate 23 by welding, forming a stable support for the roller 1, so that the roller 1 can run smoothly. Through the arrangement of the adjustment hole 22 and the through hole 21, the adjustment mechanism 4 can smoothly drive the roller seat 2 to move, thereby realizing the adjustment of the position of the roller seat 2.

[0046] Furthermore, the roller seat 2 also includes a reinforcing rib 25. The first end of the reinforcing rib 25 is welded and fixed to the base plate 23, and the second end of the reinforcing rib 25 is welded and fixed to the vertical plate 24. The reinforcing rib 25 is arranged on the side of the vertical plate 24 away from the roller 1.

[0047] It is understood that the stiffening ribs 25 are welded and fixedly connected to the base plate 23 and the upright plate 24 to strengthen the connection rigidity between the upright plate 24 and the base plate 23, and to prevent the upright plate 24 from being damaged by irreversible deformation during use.

[0048] Furthermore, the base 3 is provided with a plurality of transverse strip holes 32, and the roller seat 2 is provided with a plurality of longitudinal strip holes 231. The transverse strip holes 32 and the longitudinal strip holes 231 are arranged in a one-to-one correspondence, and the longitudinal strip holes 231 are arranged on the base plate 23; it also includes fastening bolts 5, which are arranged to pass through the transverse strip holes 32 and the longitudinal strip holes 231 in sequence.

[0049] It is known that the roller seat 2 and the base 3 are locked by the fastening bolt 5. When the roller seat 2 needs to be adjusted, the fastening bolt 5 is loosened and the position of the roller seat 2 is adjusted by the adjustment mechanism 4. After the adjustment is completed, the fastening bolt 5 is tightened to fix the roller seat 2 to the base 3. With the setting of the transverse strip hole 32 and the longitudinal strip hole 231, the roller seat 2 can still move horizontally relative to the base 3 when the fastening bolt 5 passes through the transverse adjustment hole 22 and the longitudinal adjustment hole 22 during the adjustment process. With the setting of the transverse adjustment hole 22 and the longitudinal adjustment hole 22, the roller seat 2 can move horizontally relative to the base 3 and can be locked at any position by the fastening bolt 5.

[0050] Furthermore, it also includes an adjusting pad 6, which is arranged between the roller seat 2 and the base 3, and the roller seat 2 is supported on the base 3 by the adjusting pad 6.

[0051] It should be noted that during the manufacturing process, the plane on which the base 3 is used to install the roller seat 2 may have a height difference due to manufacturing errors, that is, the surface of the base 3 used to install the roller seat 2 is not flat; secondly, the roller 1 will wear during use. When the wear is too great, a gap may easily appear between the roller 1 and the rotating frame trolley 7 of the ring cooler, resulting in the inability to provide stable support.

[0052] It can be seen that by adjusting the setting of the pad 6, on the one hand, the surface of the base 3 used to install the roller seat 2 can be made flatter, and on the other hand, the height of the roller seat 2 and the roller 1 can be adjusted by adjusting the pad 6, so that the roller 1 can stably support the rotating frame trolley 7 of the ring cooler.

[0053] The working principle and operation process of this utility model are as follows:

[0054] When roller 1 needs adjustment, first loosen all the fastening bolts 5 and loosen the locking nuts 426 on the two adjusting mechanisms 4. Measure the angle of roller 1 using an external measuring device to determine the direction and amount of adjustment required. Then adjust the adjusting nut 427 in the adjusting mechanism 4 while measuring until the adjustment is in place. After adjustment, tighten the locking nut 426 and the fastening bolts 5 to achieve the adjustment of roller 1 angle. The entire adjustment process is done by rotating the adjusting nut 427, which is more accurate and convenient than adjusting by striking with a hammer.

[0055] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
