Description

Technical Field

[0001] The present application belongs to the technical field of ring cooler equipment, and in particular relates to a support wheel for a sintering ring cooler. Background Art

[0002] Annular cooler is the abbreviation of annular cooler. Its function is to effectively cool the sintered hot ore unloaded from the sintering machine. It is widely used in metallurgy, chemical industry, building materials and other industries. In many production processes, after the materials are produced at high temperature, they need to be quickly cooled by an annular cooler in order to proceed to the next step of processing or packaging.

[0003] With the development of large-scale equipment, the scale of sintering supporting ring coolers has gradually become larger. Due to the increase in the scale of the ring cooler, the weight of the ring cooler's rotating frame and the sintered ore inside the trolley body have increased significantly. The original ring cooler structure can no longer withstand the heavy load, which can easily cause the large-scale ring cooler to deviate and deform the structure. The problem is easily exposed and relatively more serious.

[0004] The support wheels are an important component of the ring cooler and are evenly arranged around the circumference. They bear the weight of the ring cooler's rotating frame and the weight of the sintered ore inside the trolley. The load borne by a single support wheel is very large, especially the support wheels in large ring coolers. Problems encountered during the use of the support wheels include: 1. The roller surface of the support wheel is prone to wear and fall off; 2. The risk of peeling of the support wheel. Utility Model Content

[0005] The present application aims to solve the technical problems of wear and peeling of the support wheel of the ring cooler to at least a certain extent. To this end, the present application provides a support wheel for a sintering ring cooler, which can effectively solve the problems of wear and peeling of the roller surface of the support wheel, extend the overall service life, and do not need to disassemble the support wheel during later maintenance, which is convenient for replacement and reduces repair costs and workload.

[0006] The embodiment of the present application provides a support wheel for a sintering ring cooler, comprising:

[0007] The support and roller include a roller body and a wear-resistant sleeve. The wear-resistant sleeve is fixed on the roller surface of the roller body by sleeve arrangement. The wear-resistant sleeve and the roller body have an interference fit. The support is used to install and fix the roller body.

[0008] The existing technology improves the hardness and wear resistance of the roller surface by surface quenching the support wheel, which can solve the problem of wear and falling off of the support wheel to a certain extent. However, for the situation where the support wheel bears a large load, especially the support wheel in a large annular cooler, the surface quenching method cannot solve the wear and falling off problem well, and the existing technology cannot meet the needs. The present application sets a wear-resistant sleeve on the roller surface of the roller body, which can be used as a component in contact with the top to bear the deadweight of the rotating frame of the annular cooler and the weight of the sintered ore, and converts the original roller's direct support of the top into the wear-resistant sleeve's support of the top, which will not directly cause wear to the roller body. The original surface quenching layer is improved to a wear-resistant sleeve, which increases the wear-resistant thickness, can further enhance the wear resistance, and prevent the outer part of the roller from falling off. It can effectively solve the roller surface wear and peeling problem of the support wheel and extend the overall service life. If the wear-resistant sleeve is damaged and needs to be replaced, the support wheel does not need to be disassembled for later maintenance, and only the wear-resistant sleeve needs to be replaced, which is convenient for replacement and reduces the repair cost and workload.

[0009] In an optional embodiment, the roller surface of the roller body or the contact surface of the wear-resistant sleeve facing the roller body are matched with each other in a concave-convex manner.

[0010] In an optional embodiment, the outer peripheral surface of the wear-resistant sleeve is provided with a layer structure of wear-resistant material or the wear-resistant sleeve is a ring structure of wear-resistant material.

[0011] In an optional embodiment, the support wheel further includes a support shaft, the support is provided with a groove, both ends of the support shaft are respectively connected to the support and placed in the groove, and the support shaft and the roller body are in a shaft sleeve matching relationship.

[0012] In an optional embodiment, the support wheel further includes a bearing, the bearing is sleeved on the support shaft, the roller body is sleeved on the bearing, and the roller body is rotatable relative to the support shaft through the bearing.

[0013] In an optional embodiment, the support wheel further includes a locking mechanism, which includes a positioning lock nut. Positioning lock nuts are provided on both sides of the bearing, and the bearing is clamped in the groove through the positioning lock nut.

[0014] In an optional embodiment, the locking mechanism further includes a roller end cover, which is sleeved on the positioning lock nut, and the two sides of the roller are clamped and fixed by the roller end cover.

[0015] In an optional embodiment, the locking mechanism further includes a locking plate, a notch is provided on the outer circumferential surface of the support shaft, the locking plate is snapped into the notch, and the locking plate is fixedly connected to the support.

[0016] In an optional embodiment, the locking mechanism further includes a shaft end cover, which is connected to both ends of the support shaft, and the support shaft is clamped to the support through the shaft end cover.

[0017] In an optional embodiment, an oil channel is provided in the support shaft, one end of the oil channel is connected to one end of the support shaft, and the other end of the oil channel is connected to the contact surface of the support shaft and the bearing.

[0018] It can be seen from the above technical solution that the beneficial effects of this application are:

[0019] The support wheel of the present application is provided with a wear-resistant sleeve on the roller surface of the roller body, so that the wear-resistant sleeve can be used as a component in contact with the top to bear the deadweight of the rotating frame of the ring cooler and the weight of the sintered ore, and the original direct support of the roller to the top is converted into support of the top by the wear-resistant sleeve, which will not directly cause wear to the roller body. The original surface quenching layer is improved to the wear-resistant sleeve, which increases the wear-resistant thickness, can further enhance the wear resistance, and prevent the outer part of the roller from falling off, can effectively solve the roller surface wear and peeling problems of the support wheel, and extend the overall service life. If the wear-resistant sleeve is damaged and needs to be replaced, the support wheel does not need to be disassembled for later maintenance, and the wear-resistant sleeve only needs to be replaced, which is convenient for replacement and reduces the repair cost and workload.

[0029] The present application is described below with reference to specific embodiments and with reference to the accompanying drawings:

[0030] Please refer to Figure 1 and Figure 2The first embodiment of the present application provides a support wheel for a sintering ring cooler, wherein the support wheel 100 includes a support 110 and a roller 130, and the roller 130 includes a roller body 131 and a wear-resistant sleeve 132. The roller body 131 is set to be annular with a through hole in the middle of the ring. The roller body 131 is connected to the support 110 through the through hole, and the roller body 131 can rotate around the through hole. The outer peripheral surface of the roller body 131 is the roller surface, and the wear-resistant sleeve 132 is annular. The wear-resistant sleeve 132 is fixed on the roller surface of the roller body 131 by a sleeve arrangement. The wear-resistant sleeve 132 is interference fit with the roller body 131, thereby adding a layer of annular structure to the outer edge of the original roller 130; since the roller 130 needs to provide support to the outside, while ensuring that the outer diameter remains unchanged, the roller 130 is set to two parts: the roller body 131 and the wear-resistant sleeve 132, which can provide support to the outside through the wear-resistant sleeve 132. The support 110 is used to install and fix the roller body 131. The support 110 can adopt the existing support 110 structure. For example, if a connecting shaft is required, the connecting shaft is fixed to the support 110, and both ends of the connecting shaft are fixed through the support 110. The roller body 131 of the roller 130 is sleeved on the connecting shaft, so that the roller body 131 can rotate relative to the support 110. In other embodiments, other structural forms can also be adopted. It is necessary to fix the support 110 to the working area, such as fixing the support 110 to the ground by screws and welding. The above fixing method adopts welding, bolting or other connection methods. In an optional embodiment, the outer peripheral surface of the wear-resistant sleeve 132 is provided with a layer structure of wear-resistant material, that is, the wear-resistant sleeve 132 is made of wear-resistant material at least on the outer peripheral surface of the annular structure. In the optional embodiment, the wear-resistant sleeve 132 is a ring structure of wear-resistant material, that is, the entire wear-resistant sleeve 132 is made of wear-resistant material, providing better wear resistance.

[0031] The present application sets a wear-resistant sleeve 132 on the roller surface of the roller body 131, so that the wear-resistant sleeve 132 can be used as a component in contact with the top to bear the deadweight of the rotating frame of the ring cooler and the weight of the sintered ore, and converts the original roller 130's direct support of the top into the wear-resistant sleeve 132's support of the top, which will not directly cause wear to the roller body 131. The original surface quenching layer is improved to the wear-resistant sleeve 132, which increases the wear-resistant thickness, can further enhance the wear resistance, and prevent the roller 130 from falling off. It can effectively solve the roller surface wear and peeling problems of the support wheel 100 and extend the overall service life. If the wear-resistant sleeve 132 is damaged and needs to be replaced, the support wheel 100 does not need to be disassembled for later maintenance, and the wear-resistant sleeve 132 only needs to be replaced, which is convenient for replacement and reduces the repair cost and workload.

[0032] Please refer to Figure 3In an optional embodiment, the inner side surface of the wear-resistant sleeve 132 facing the roller surface is recorded as the contact surface, and the roller surface of the roller body 131 or the contact surface of the wear-resistant sleeve 132 facing the roller body 131 is concave-convex matching, that is, the roller surface of the roller body 131 is provided with a boss or the contact surface of the wear-resistant sleeve 132 is provided with a boss, and the roller surface of the roller body 131 and the contact surface of the wear-resistant sleeve 132 match each other, thus forming a concave-convex matching method. In an optional embodiment, the boss surrounds the roller body 131 or the boss is provided around the contact surface of the wear-resistant sleeve 132. In an optional embodiment, the roller surface of the roller 130 is provided with a groove 133, and the contact surface of the wear-resistant sleeve 132 is convex toward the roller 130. The roller surface of the roller 130 and the wear-resistant sleeve 132 match each other, so that the wear-resistant The wearing sleeve 132 can be clamped on the roller 130 by means of concave-convex matching; in an optional embodiment, a groove 133 is provided on the inner side of the wear-resistant sleeve 132 facing the roller surface, that is, the contact surface of the wear-resistant sleeve 132 is concave, and the roller surface of the roller 130 is convex outward, and the roller surface of the roller 130 and the wear-resistant sleeve 132 match, so that the wear-resistant sleeve 132 can be clamped on the roller 130 by means of concave-convex matching; in an optional embodiment, the groove 133 is set as an annular groove, that is, the roller surface of the roller 130 or the contact surface of the wear-resistant sleeve 132 is concave inwardly provided with a circle of annular groove, and the corresponding wear-resistant sleeve 132 or roller 130 is matched with concave-convex settings, so that the wear-resistant sleeve 132 can be clamped on the roller surface of the roller 130, thereby increasing the stability of the wear-resistant sleeve 132. The groove 133 prevents the wear-resistant sleeve 132 from axial movement, so that the wear-resistant sleeve 132 can be stably fixed on the roller surface of the roller 130 and can also prevent the wear-resistant sleeve 132 from falling off.

[0033] Please refer to Figure 2In an optional embodiment, the support wheel 100 also includes a support shaft 120, and the support 110 is provided with a groove 133. Both ends of the support shaft 120 are respectively connected to the support 110 and placed in the groove 133. The longitudinal cross-section of the groove 133 can be set to a circle with a step structure, so that the roller 130 can be stuck in the groove 133; in an optional embodiment, the groove 133 is also matched with the bearing 140, the positioning lock nut 151 and other structures to provide an accommodating space; the support shaft 120 and the roller body 131 are in a shaft sleeve matching relationship, and the roller body 131 is sleeved on the outer periphery of the support shaft 120, so that the roller body 131 can rotate relative to the support 110. In an optional embodiment, the support wheel 100 further includes a bearing 140, that is, a bearing 140 is provided on the basis of the above-mentioned support shaft 120, and the roller body 131 is indirectly connected to the support shaft 120 via the bearing 140. Specifically, the bearing 140 is sleeved on the support shaft 120, and the roller body 131 is sleeved on the bearing 140. The roller body 131 is rotatable relative to the support shaft 120 via the bearing 140, thereby increasing the smoothness of rotation of the roller wheel 130. In an optional embodiment, an oil passage 121 is provided in the support shaft 120, one end of the oil passage 121 is connected to one end of the support shaft 120, and the other end of the oil passage 121 is connected to the contact surface between the support shaft 120 and the bearing 140. The provision of the oil passage 121 is to increase the smoothness of rotation between the bearing 140 and the support shaft 120, thereby facilitating lubrication.

[0034] Please refer to Figure 2 In an optional embodiment, the support wheel 100 further includes a locking mechanism 150. Since the wear-resistant layer generally has a higher hardness, the surface hardness is increased to resist pressure and improve wear resistance. However, after the hardness of the wear-resistant sleeve 132 is increased, the roller 130 may be at risk of structural deviation and deformation. The locking mechanism 150 is provided to solve this problem. The locking mechanism 150 includes a positioning lock nut 151, which is annular and sleeved on the outer periphery of the support shaft 120, and the inner side of the ring of the positioning lock nut 151 can just clamp the support shaft 120, so that the positioning lock nut 151 is placed in the groove 133, and positioning lock nuts 151 are provided on both sides of the bearing 140. The side surfaces of the positioning nut are close to the two sides of the bearing 140, and the bearing 140 is clamped in the groove 133 by the positioning lock nut 151. The width of the positioning nut is the same as the remaining width of the space in the groove 133 except the space occupied by the bearing 140, so that both sides of the positioning nut can be clamped in the groove 133; the setting of the positioning lock nut 151 is to prevent the roller 130 from structural deviation and deformation. The position of the roller 130 can be adjusted by the positioning lock nut 151, and the bearing 140 is clamped, thereby indirectly fixing the roller 130 so that the roller 130 can rotate stably.

[0035] Please refer to Figure 2In an optional embodiment, the locking mechanism 150 further includes a roller end cover 152. The roller end cover 152 is annular. The inner side of the roller end cover 152 matches the outer periphery of the positioning lock nut 151. The roller end cover 152 is sleeved on the positioning lock nut 151. Both sides of the roller 130 are clamped and fixed by the roller end covers 152. In this way, the connection between the roller 130 and the bearing 140 can be enclosed by the roller end covers 152, which increases the stable connection between the roller 130 and the bearing 140, so that the roller 130 can be positioned and stably rotated by the two roller end covers 152. In an optional embodiment, the outer diameter of the bearing 140 is larger than The outer diameter of the positioning lock nut 151 is equal to the outer diameter of the bearing 140, and the outer diameter of the roller end cover 152 is smaller than the outer diameter of the roller end cover 152. The interior of the roller end cover 152 is precisely abutted and locked against both sides of the bearing 140. In this way, the roller end cover 152 can position and lock the roller 130. In an optional embodiment, the roller end cover 152 is bolted to the roller body 131. In an optional embodiment, grooves are provided on both sides of the roller body 131 near the inner edge. The grooves are shallow, forming a step-like shape on both sides of the roller body 131. The roller end cover 152 is precisely locked into the grooves, which can further increase the rotation stability of the roller 130. This arrangement can further prevent the roller 130 from structural deviation and deformation, allowing the roller 130 to rotate stably.

[0036] Please refer to Figure 2 In an optional embodiment, the locking mechanism 150 further includes a locking plate 153, which is in the shape of a plate, block or strip, and has a notch on the outer peripheral surface of the support shaft 120. As shown in the figure, a notch is opened at the top of the support shaft 120, and the notch is located in the groove 133. The shape and size of the bottom end of the locking plate 153 just match the notch, and the locking plate 153 is stuck in the notch, thus forming an indirect clamping structure between the support 110 and the support shaft 120. The locking plate 153 is fixedly connected to the support 110, and welding, bolting or other connection methods can be adopted. For example, threaded holes are provided at both ends of the locking plate 153, and the locking plate 153 is fixed to the support 110 with screws, thereby further strengthening the connection strength between the support shaft 120 and the support 110. In an optional embodiment, the locking mechanism 150 also includes a shaft end cover 154, which is connected to both ends of the support shaft 120. The shape of the shaft end cover 154 is the same as the end shape of the support shaft 120. The edge of the shaft end cover 154 can be clamped on the support 110. The end cover is provided with a bolt hole, and the side of the shaft end cover 154 is fixed by bolt connection, so that the support shaft 120 is clamped to the support 110 through the shaft end cover 154.
