Description

Technical Field

[0001] The utility model relates to the technical field of annular cooler equipment, in particular to a rotary frame structure and a rotary frame of an annular cooler. Background Art

[0002] The rotary frame and the trolley are the rotary moving parts of the annular cooler, which rotate in the horizontal plane and are used for cooling and discharging high-temperature sintered ore materials. The rotary frame is of a fan-shaped structure, usually with large external dimensions, and is composed of an outer ring beam, a circular tube beam and an inner ring beam welded into a rigid body; the two ends of the outer ring beam and the inner ring beam of the rotary frame are flanges with holes, and bolts and nuts are inserted into the holes during on-site installation, so that several identical rotary frames are combined into a complete circumference, and several groups of bearing seats are arranged in pairs at a certain angle on the inner ring beam and the outer ring beam of the rotary frame to install the trolley shaft, thereby supporting the trolley.

[0003] Since the rotary frame is a welded structure, the inner and outer ring flanges are respectively welded to the top plate, the bottom plate and adjacent parts of the ring beam. There are mainly two types of existing technical solutions, one is surface-mounted welding and the other is embedded welding; the main disadvantage of flange surface-mounted welding is that it is impossible to avoid the dimensional changes caused by weld shrinkage, which affects the overall shape of the rotary frame. Even if the flanges at both ends can be positioned by welding jigs, due to the shrinkage of the weld during welding, the positions of the flanges will change, and it is impossible to ensure the fan angle A, chord length, diagonal and other dimensions of the structural unit.

[0004] The main disadvantage of flange embedded welding is that it has high requirements for the external dimensions of the top plate and the bottom plate of the ring beam. If the cutting dimensions of the top plate and the bottom plate are inaccurate, the outer surface of the flange cannot be flush with the end faces of the top plate and the bottom plate, which affects the appearance; and since the transverse weld is on the outer surface of the flange, it will affect the on-site assembly of the rotary frame, so this weld must be ground, which will damage the flatness of the flange surface; when grinding the weld, the angle grinder operates in the vertical plane, with high labor intensity; the weld is in the vertical plane, and the welding operation is not as convenient as in the horizontal plane, and the weld formation is not good.

[0005] In view of this, it is necessary to provide a rotary frame structure and a rotary frame of an annular cooler to solve or at least alleviate the above defects. Summary of the Utility Model

[0039] Please refer to the attached Figures 1-9 , a rotary frame structure of a ring cooler provided in an embodiment of the present utility model includes an inner ring structure, an outer ring structure, a circular pipe beam, and a positioning component. The circular pipe beam is arranged between the inner ring structure and the outer ring structure. First, it should be noted that different from the main disadvantage of the flange facing welding in the prior art that it is impossible to avoid the dimensional variation caused by weld shrinkage, which affects the overall shape of the rotary frame, and the main disadvantage of the flange embedded welding is that it has high requirements for the outer shape dimensions of the ring beam top plate and bottom plate. If the cutting dimensions of the top plate and bottom plate are inaccurate, the outer surface of the flange cannot be flush with the end surfaces of the top plate and bottom plate, affecting the appearance. The present application solves the above defects in the prior art by providing a rotary frame structure and a rotary frame of a ring cooler. Specifically as follows:

[0040] The inner ring structure 10 includes an inner ring beam 110 and two inner ring flanges 120. The outer ring structure 20 includes an outer ring beam 210 and two outer ring flanges 220. The outer ring beam 210 and the inner ring beam 110 are arranged at intervals in the radial direction, and the circular pipe beam 30 is connected between the outer ring beam 210 and the inner ring beam 110. Among them,

[0041] The two inner ring flanges 120 are oppositely connected to both sides of the inner ring beam 110 along the circumferential direction of the inner ring beam 110. An inner ring boss 121 is convexly provided on the side of the inner ring flange 120 close to the inner ring beam 110. The top plate of the inner ring beam 110 is connected to the top end of the inner ring boss 121, and the bottom plate of the inner ring beam 110 is connected to the bottom end of the inner ring boss 121. The positioning component 40 is fixed between the inner ring boss 121 and the top plate of the inner ring beam 110, and between the inner ring boss 121 and the bottom plate of the inner ring beam 110;

[0042] Two of the outer ring flanges 220 are oppositely connected to both sides of the outer ring beam 210 along the circumferential direction of the outer ring beam 210. An outer ring boss 221 is protrudingly formed on one side of the outer ring flange 220 close to the outer ring beam 210. The top plate of the outer ring beam 210 is connected to the top end of the outer ring boss 221, and the bottom plate of the outer ring beam 210 is connected to the bottom end of the outer ring boss 221. The positioning assemblies 40 are fixed between the outer ring boss 221 and the top plate of the outer ring beam 210, and between the outer ring boss 221 and the bottom plate of the outer ring beam 210.

[0043] Specifically, the rotary frame structure of the annular cooler in this application is a fan-shaped structure. Therefore, it includes an inner ring structure 10, an outer ring structure 20, and a circular tube beam 30. The inner ring structure 10 and the outer ring structure 20 are arranged at intervals in the radial direction to form a fan-shaped structure. The inner ring structure 10 includes an inner ring beam 110 and two inner ring flanges 120. The outer ring structure 20 includes an outer ring beam 210 and two outer ring flanges 220. They are both common structural forms in the rotary frame structure. The function of the flange is to facilitate the connection of two adjacent rotary frame structures. They are usually arranged oppositely along the circumferential direction on both sides of the ring beam. Then, the inner ring structure 10 and the outer ring structure 20 are connected by the circular tube beam 30 to form a rotary space for the movement of the annular cooler trolley. Therefore, the circular tube beam 30 is connected between the outer ring beam 210 and the inner ring beam 110, and bearing seats for installing bearings are provided on both the inner ring beam 110 and the outer ring beam 210. Since this is a common technical feature, it will not be elaborated here in detail. The rotary frame structure in this application further includes a positioning assembly 40, and the positioning assembly 40 is used to play a positioning role when the inner ring structure 10 and the outer ring structure 20 are welded internally to control shrinkage deformation.

[0044] Among them, an inner ring boss 121 is convexly formed on one side of the inner ring flange 120 close to the inner ring beam 110. The inner ring boss 121 is used to connect with the top plate and the bottom plate of the inner ring beam 110. Under the action of the inner ring boss 121, the top plate of the inner ring beam 110 is in close contact with the top end of the inner ring boss 121, and the bottom plate of the inner ring beam 110 is in close contact with the bottom end of the inner ring boss 121. In this way, the distance between the top plate and the bottom plate of the inner ring beam 110 can be strictly ensured to be consistent, thereby ensuring the flatness of the flange surface. Then, the positioning assembly 40 is fixedly arranged between the inner ring boss 121 and the top plate of the inner ring beam 110, and between the inner ring boss 121 and the bottom plate of the inner ring beam 110. Through the mutual abutting action of the positioning assembly 40 between the inner ring boss 121 and the top and bottom plates of the inner ring beam 110, the shrinkage and depression of the flange during the welding process are controlled, effectively ensuring the consistency of the overall shape of the slewing frame structure. It should be noted that the structure of the outer ring boss 221 of the outer ring flange 220 is similar to that of the inner ring boss 121, that is, the top plate of the outer ring beam 210 is in close contact with the top end of the outer ring boss 221, and the bottom plate of the outer ring beam 210 is in close contact with the bottom end of the outer ring boss 221, so as to ensure that the distance between the top and bottom plates is consistent to form a flat flange surface, and the positioning assembly 40 is added between the outer ring boss 221 and the top and bottom plates of the outer ring beam 210 to prevent the shrinkage and depression of the outer ring flange 220.

[0045] As a preferred embodiment of the present invention, the positioning assembly 40 includes a plurality of rib plates 410. The rib plates 410 are fixed between the inner ring boss 121 and the top plate of the inner ring beam 110, and between the inner ring boss 121 and the bottom plate of the inner ring beam 110. The rib plates 410 are also fixed between the outer ring boss 221 and the top plate of the outer ring beam 210, and between the outer ring boss 221 and the bottom plate of the outer ring beam 210, and the plurality of rib plates 410 are arranged at intervals in the radial direction.

[0046] It should be noted that the rib plates 410 can increase the structural bearing capacity and reduce the structural deformation. They have strong bending resistance and can significantly reduce the shrinkage between structures. Therefore, they are arranged between the inner ring boss 121 and the top plate of the inner ring beam 110, between the inner ring boss 121 and the bottom plate of the inner ring beam 110, between the outer ring boss 221 and the top plate of the outer ring beam 210, and between the outer ring boss 221 and the bottom plate of the outer ring beam 210. In this way, the outer ring boss 221 and the outer ring beam 210 are positioned, and the inner ring boss 121 and the inner ring beam 110 are positioned. Under the supporting action of the rib plates 410, the outer ring flange 220 and the inner ring flange 120 will not have shrinkage grooves during the welding process, thereby ensuring the consistency of the structural dimensions of the slewing frame.

[0047] As a preferred embodiment of the present utility model, the inner ring flange 120 and the end face of the inner ring beam 110, as well as the outer ring flange 220 and the end face of the outer ring beam 210 are fixedly connected by welding, and the welds between the inner ring flange 120 and the end face of the inner ring beam 110, as well as the welds between the outer ring flange 220 and the end face of the outer ring beam 210 are groove welds 510.

[0048] It should be noted that when welding and fixing, welding is performed between the end faces of the inner ring flange 120 and the inner ring beam 110. The end faces here refer to (after the top plate of the inner ring beam 110 is tightly attached to the top of the inner ring boss 121, the side of the top plate of the inner ring beam 110 facing the inner ring flange 120 and the inner ring flange 120; and after the bottom plate of the inner ring beam 110 is tightly attached to the bottom end of the inner ring boss 121, the side of the bottom plate of the inner ring beam 110 facing the inner ring flange 120 and the inner ring flange 120). In this way, the weld will not be on the outer surface of the flange, so it will not affect the on-site assembly of the revolving frame, and the weld is moved from the vertical plane to the horizontal plane (the horizontal weld becomes Flat weld), its welding operation is more convenient, the weld formation is more beautiful, when grinding the weld, the angle grinder does not need to be lifted laboriously like in the existing operation, but is placed flat on the weld on the horizontal plane for grinding, the labor intensity of weld grinding is significantly reduced, and the efficiency is significantly improved; further, the weld between the inner ring flange 120 and the end face of the inner ring beam 110 is a groove weld 510, and the groove weld 510 has low stress concentration, high weld quality and good fatigue resistance; it is worth mentioning that the connection between the outer ring flange 220 and the end face of the outer ring beam 210 is similar to the inner ring flange 120, and also adopts the same welding connection method, and its effect can be directly referred to the inner ring flange 120, so it is not described in detail here.

[0049] It is worth mentioning that positioning welding can be applied at the groove of the flange to determine the radial position of the top plate (or bottom plate).

[0050] As a preferred embodiment of the utility model, the inner ring boss 121 and the inner ring beam 110, as well as the outer ring boss 221 and the outer ring beam 210 are fixedly connected by welding, and the welds between the inner ring boss 121 and the inner ring beam 110, as well as the outer ring boss 221 and the outer ring beam 210 are fillet welds 520.

[0051] It should be noted that, in addition to welding between the end faces of the inner ring flange 120 and the inner ring beam 110, in order to ensure the connection effect, welding is also required between the inner ring boss 121 and the inner ring beam 110. Here, it refers to between the side wall surface of the inner ring boss 121 and the top plate of the inner ring beam 110, and between the side wall surface of the inner ring boss 121 and the bottom plate of the inner ring beam 110. The fillet weld 520 connection method is adopted, which is more convenient during construction welding, and has better welding strength and durability.

[0052] As a preferred embodiment of the present utility model, a plurality of groups of flange holes 122 arranged at intervals in the vertical direction are provided on both the inner ring flange 120 and the outer ring flange 220. Each group of flange holes 122 includes a plurality of flange holes 122 arranged at intervals in the radial direction.

[0053] It should be noted that since the heights of the slewing frames of each project are almost the same, the dimensions in the height direction are fixed and consistent; and each group of flange holes 122 includes a plurality of flange holes 122 arranged at intervals in the radial direction. During welding, the flange needs to be first position-welded with the flange positioning welding tooling for positioning. Since the adjacent hole spacing of the drilled holes in the flange positioning welding tooling in the horizontal direction is a multiple of 50, the spacing between two adjacent flange holes 122 in the horizontal direction (radially spaced arrangement) in each group of flange holes 122 can also be set as a multiple of 50. In this way, the corresponding points can be better found during the connection of the corresponding tooling, and the adaptability is better; in a preferred embodiment, the spacing between two adjacent flange holes 122 in each group of flange holes 122 is 100 mm to 250 mm, and the dimensions can be taken as 100 mm, 150 mm, 200 mm, 250 mm, just set as a multiple of 50; among them, if the dimensions are larger in other project sizes, values above 250 mm can also be taken, such as 300 mm, 350 mm, 400 mm, etc., and the specific value of the spacing needs to be set as a multiple of 50, and can be specifically selected according to the actual size specifications of the flange.

[0054] Furthermore, a gap is reserved between the end faces of the inner ring flange 120 and the inner ring beam 110, and between the end faces of the outer ring flange 220 and the outer ring beam 210.

[0055] It should be understood that reserving such a gap can make the arc length of the top plate (or bottom plate) smaller than the theoretical maximum value, so as to reduce the precision requirements for the cutting of the top plate (or bottom plate), increase the error tolerance range within the allowable range of dimensional changes, and the slewing frame can be smoothly hoisted into the tooling for group welding without affecting the overall dimensional accuracy; in a relatively optimal embodiment, the gap distance is within 2 mm, so the arc length of the top plate (or bottom plate) can be 4 mm smaller than the theoretical maximum value.

[0056] Furthermore, the circumferential protruding width of the inner ring boss 121 and the outer ring boss 221 is 10 mm to 15 mm.

[0057] It should be noted that the larger the circumferential protruding width of the inner ring boss 121 and the outer ring boss 221 is, the easier it is for the top plate (or bottom plate) to fit closely. However, it will greatly increase the processing cost and construction difficulty. Therefore, the circumferential protruding width of the inner ring boss 121 and the outer ring boss 221 can be set to 10 mm to 15 mm. Preferably, it is set to 10 mm, and those skilled in the art can set it according to needs.

[0058] The present application also provides a rotary frame, which includes a rotary frame structure of a plurality of ring coolers as described above, and the rotary frame structures of the plurality of ring coolers are sequentially connected in the circumferential direction.

[0059] It can be understood that after the rotary frame structures of the ring coolers in a plurality of the present applications are sequentially closed and connected in the circumferential direction, a complete rotary frame can be formed. After closing and passing the installation adjustment, the welding groove can be filled with welds to avoid loosening.

[0060] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the specification and drawings of the present invention, or directly or indirectly applied to other related technical fields, shall be equally included in the patent protection scope of the present invention.
