Description

Technical Field

[0001] The invention belongs to the technical field of annular coolers, and in particular relates to a rotation body deviation correction structure. Background Art

[0002] Currently, ring coolers are primarily used to cool hot sintered ore during the pre-iron sintering process in the metallurgical industry. Their main operating mechanism consists of a rotating body driven by two to three sets of friction or pin-tooth transmissions, rotating along a central axis. Because the ring cooler's rotating body is assembled from multiple fan-shaped rotating frames, its rotation radius is large, and its supporting mechanism consists of multiple support rollers evenly distributed circumferentially around its lower portion. This can easily lead to deviations during operation, resulting in operational failures. In severe cases, this can force the ring cooler to shut down, significantly impacting production.

[0003] The annular cooler has multiple side rollers evenly distributed around its circumference. These rollers are designed to restrict the position of the rotor when radial deviation reaches a certain level, preventing further deviation. However, existing side rollers are unable to correct any deviation that has already occurred before the rollers interact with the device and therefore lack a corrective function. Summary of the Invention

[0004] To address the problems in the prior art, such as the side rollers failing to correct the deviation of the rotating body that has already occurred before interacting with them and lacking a corrective function, the present invention provides a rotating body correcting structure. This structure uses a linear telescopic device to drive the rollers to move horizontally toward the rotating body, generating a squeezing force on the rotating body, causing it to gradually return to its normal trajectory as it rotates. This corrects the deviation that has already occurred, achieving the purpose of correcting the annular cooler. The specific technical solution is as follows:

[0005] A rotating body correction structure is arranged at a stop roller base on a ring cooler frame, and the correction structure includes: a stop roller, a linear telescopic device and a limit connection assembly; the stop roller is arranged on a side of the stop roller base close to the rotating body of the ring cooler, and the stop roller is movably connected to the stop roller base; the linear telescopic device is arranged perpendicular to the axial direction of the rotating body, the fixed end of the linear telescopic device is arranged on the frame, and the telescopic end of the linear telescopic device is arranged on the stop roller, and the linear telescopic device can drive the stop roller to move in the horizontal direction; the stop roller is slidably connected to the limit connection assembly, the first end of the limit connection assembly is arranged on the stop roller base, and the second end of the limit connection assembly is used to limit the stop roller.

[0006] In addition, a rotation body correction structure in the above technical solution provided by the present invention may also have the following additional technical features:

[0007] Optionally, a plurality of retaining roller bases are evenly arranged on the frame along the circumference of the rotating body.

[0008] Optionally, the linear telescopic device is symmetrically arranged on the upper and lower sides of the retaining roller.

[0009] Optionally, the stop roller includes: a mounting plate, a mounting frame and a stop roller body; the mounting plate is slidably connected to the limiting connection assembly; the mounting frame is connected to the mounting plate, and the mounting frame is arranged on the telescopic end of the linear telescopic device; the stop roller body is rotatably arranged on the mounting frame.

[0010] The support portion is disposed on the telescopic end of the linear telescopic device and is connected to the mounting frame. Connecting the mounting frame to the telescopic end of the linear telescopic device via the support portion increases the contact area between the linear telescopic device and the mounting frame, facilitating installation while also improving the stability of the connection between the mounting frame and the telescopic end, resulting in a reliable structure.

[0011] Optionally, the limiting connection assembly includes: a guide portion and a limiting portion; the guide portion passes through the stop roller base and the mounting plate in sequence, the first end of the guide portion is connected to the stop roller base, and the guide portion is slidably connected to the mounting plate; the limiting portion is arranged on the guide portion, the limiting portion is located on the side of the mounting plate close to the rotating body, and the limiting portion is used to limit the horizontal movement of the mounting frame.

[0012] Optionally, an external thread is provided on the outer wall of the guide portion, and an internal thread is provided on the inner wall of the limiting portion. The limiting portion and the guide portion are threadedly connected to adjust the relative position between the limiting portion and the guide portion.

[0013] Optionally, the linear telescopic device is hydraulically driven.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This structure drives the stop roller to move horizontally toward the rotating body through a linear telescopic device, which can generate an extrusion force on the rotating body, so that the rotating body gradually returns to its normal running trajectory as its own rotational motion proceeds, thereby correcting the deviation that has already formed, achieving the purpose of correcting the deviation of the ring cooler and preventing the deviation phenomenon from further aggravation.

[0016] This structure ensures that the stop roller can make stable horizontal movement within a certain range by setting a limit connection component between the stop roller base and the mounting plate, preventing the stop roller from moving too far during the correction process, thereby avoiding the problem of reverse deviation of the rotating body during the correction process, ensuring the efficiency of the correction, improving the timeliness of the correction, and preventing equipment operation failures.

[0017] This structure makes full use of the side roller device in the original structure of the ring cooler equipment, has a simple structure, and is easy to install and operate. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0025] See also Figure 1As shown, according to an embodiment of the present application, a rotating body correction structure is provided, and the correction structure is arranged at the stop roller base 12 on the annular cooler frame 10, and the correction structure includes: a stop roller 13, a linear telescopic device 14 and a limit connection assembly 15; the stop roller 13 is arranged on the side of the stop roller base 12 close to the rotating body 11 of the annular cooler, and the stop roller 13 is movably connected to the stop roller base 12; the linear telescopic device 14 is arranged perpendicular to the axial direction of the rotating body 11, the fixed end of the linear telescopic device 14 is arranged on the frame 10, and the telescopic end of the linear telescopic device 14 is arranged on the stop roller 13, and the linear telescopic device 14 can drive the stop roller 13 to move in the horizontal direction; the stop roller 13 is slidably connected to the limit connection assembly 15, the first end of the limit connection assembly 15 is arranged on the stop roller base 12, and the second end of the limit connection assembly 15 is used to limit the stop roller 13. The linear extension device 14 is extended and retracted to a certain height, thereby driving the stop roller 13 to move horizontally, gradually approaching the ring cooler rotor 11 and exerting a squeezing force on the rotor 11, causing the rotor 11 to gradually return to its normal running trajectory as it rotates, thereby correcting the deviation that has already occurred, achieving the purpose of correcting the deviation of the ring cooler and preventing the deviation from further aggravating. This structure fully utilizes the side stop roller 13 device in the original structure of the ring cooler equipment, has a simple structure, and is easy to install and operate. By providing a limit connection component 15 on the stop roller base 12 and slidably connecting the stop roller 13 to the limit connection component 15, the stop roller 13 is ensured to perform stable horizontal movement within a certain range. This not only guides the stop roller 13 and ensures the smooth movement of the stop roller 13, but also limits the maximum range of the stop roller 13's movement, preventing the stop roller 13 from moving too far during the deviation correction process, thereby avoiding the problem of reverse deviation of the rotor 11 during the deviation correction process, ensuring the efficiency of the deviation correction, improving the timeliness of the deviation correction, and preventing equipment operation failures.

[0026] Furthermore, a sensor may be provided on the frame 10 , which is electrically connected to the linear telescopic device 14 . The sensor senses whether the rotating body 11 is away from or close to the sensor at that position, thereby sending a signal to the control system, which controls the movement of the linear telescopic device 14 .

[0027] Several retaining roller bases 12 are evenly arranged on the frame 10 along the circumference of the rotating body 11. By evenly arranging the retaining roller bases 12 on the frame 10 along the circumference of the rotating body 11, the original retaining roller 13 structure of the ring cooler can be fully utilized, and multiple points of contact with the rotating body 11 can be achieved, effectively correcting any deviation that has occurred.

[0028] The linear expansion and contraction devices 14 are symmetrically arranged on the upper and lower sides of the stop roller 13. By synchronously adjusting the expansion and contraction length of the linear expansion and contraction devices 14, it is ensured that the stop roller 13 does not tilt when it is pressed against the rotating body 11 and receives the reaction force of the rotating body 11, thereby ensuring the stability of the stop roller 13 during the deviation correction and ensuring the deviation correction effect.

[0029] Furthermore, the linear telescopic device 14 adopts a separate hydraulic jack, which cooperates with a high-pressure oil pump station to achieve actions such as jacking, pushing, and squeezing. It has a large output force and can be operated remotely, making it easy to use.

[0030] Mounting plate 131 is slidably connected to the limiting connection assembly 15; mounting frame 132 is connected to mounting plate 131 and is positioned at the telescopic end of the linear telescopic device 14; and the retaining roller body 133 is rotatably mounted on mounting frame 132. Mounting plate 131 can slide on limiting connection assembly 15, which guides mounting plate 131 to prevent it from shifting and ensure that retaining roller 13 moves linearly in the horizontal direction. Mounting frame 132 is connected to mounting plate 131 and is driven to translate by the linear telescopic device 14, thereby driving mounting plate 131 to move synchronously. This guides the movement of mounting frame 132 through limiting connection assembly 15, ensuring smooth movement of mounting frame 132. By rotatably connecting the retaining roller body 133 with the mounting frame 132, the retaining roller body 133 can move synchronously with the mounting frame 132 and make rolling contact with the rotating body 11 under the drive of the mounting frame 132, thereby reducing the friction force on the rotating body 11, ensuring that the rotation speed of the rotating body 11 is not affected, and ensuring the normal operation of the equipment.

[0031] The support portion 16 is provided on the telescopic end of the linear telescopic device 14, and the support portion 16 is connected to the mounting frame 132. By providing the support portion 16 to mount the mounting frame 132 on the telescopic end, not only is it convenient to install and remove the mounting frame 132, but it also serves to limit the mounting frame 132, preventing the mounting frame 132 from tilting or deforming under the long-term action of the reaction force and gravity of the rotating body 11, thereby allowing the outer wall of the stop roller body 133 to remain parallel to the outer wall of the rotating body 11, ensuring that the stop roller body 133 can fully contact the outer wall of the rotating body 11 during deviation correction, avoiding excessive concentration of force on a certain part of the rotating body 11, and preventing damage to the outer wall of the rotating body 11.

[0032] The guide portion 151 sequentially passes through the retaining roller base 12 and the mounting plate 131. The first end of the guide portion 151 is connected to the retaining roller base 12, and the guide portion 151 is slidably connected to the mounting plate 131. A limiting portion 152 is provided on the guide portion 151. The limiting portion 152 is located on the side of the mounting plate 131 close to the rotating body 11. The limiting portion 152 is used to limit the horizontal movement of the mounting frame 132. The mounting frame 132 can slide along the guide portion 151. The limiting portion 152 limits the mounting frame 132, thereby adjusting the maximum range of motion of the retaining roller body 133, preventing the retaining roller 13 from over-moving, ensuring that the rotating body 11 is only adjusted and corrected within a certain range, and preventing it from deviating again under the pressure of the retaining roller body 133, thereby ensuring the efficiency and effectiveness of the correction.

[0033] The outer wall of the guide portion 151 is provided with an external thread, and the inner wall of the limiting portion 152 is provided with an internal thread. The limiting portion 152 is threadedly connected to the guide portion 151 to adjust the relative position between the limiting portion 152 and the guide portion 151. By threading the limiting portion 152 and the guide portion 151, it is easy to adjust the position of the guide portion 151, thereby adjusting the distance between the stop roller base 12 and the mounting plate 131, that is, adjusting the maximum range of movement of the stop roller 13. The self-locking and anti-loosening of the threads improves the stability of the guide portion 151 after adjustment, ensures the stability of the position of the stop roller 13, and prevents the stop roller 13 from moving too far.

[0034] Furthermore, the guide portion 151 and the limiting portion 152 can use matching bolts and nuts. By loosening the nuts and keeping them in a state of not being disengaged from the bolts, the motion range of the retaining roller 13 can be adjusted.

[0035] The linear telescopic device 14 is hydraulically driven. Compared to pneumatic pressure, hydraulically driven linear telescopic device 14 has a higher output pressure, and liquids are less compressible. Therefore, hydraulically driven linear telescopic device 14 has a smoother motion, and the telescopic length of the linear telescopic device 14 can be better adjusted according to the position of the rotating body 11, allowing the stop roller 13 to quickly and accurately approach the outer wall of the rotating body 11, ensuring timely and accurate correction.

[0036] It is easy for those skilled in the art to understand that, under the premise of no conflict, the above-mentioned advantageous methods can be freely combined and superimposed.

Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application. The above are merely preferred embodiments of the present application.
