Description

Technical Field

[0001] This invention relates to the field of machining technology for rotating bodies of annular coolers, and particularly to a scribing and measuring device and a measuring and machining method for rotating bodies of annular coolers. Background Technology

[0002] The annular cooler is a crucial piece of equipment used in the sintering process to cool the finished sintered ore. The current mainstream annular cooler structure includes the following components: a transmission device, a rotating body, support rollers, side rollers, pressure rails, a frame, a feed hopper, a cover, a safety device at the discharge point (cart buffer), a wind box, a discharge hopper, a discharge area cover, a double-layer ash discharge valve, and a discharge chute. The operating principle is as follows: the rotating body is placed on support rollers evenly distributed around its perimeter. The drive device, via pin gear transmission, drives the rotating body to rotate on the support rollers. The material is placed on a cart on the rotating body. The cart is supported within the rotating frame by a shaft passing through it. Since only one shaft supports the cart, a keyway is provided on the shaft to connect with the cart and prevent it from tipping over. A keyway is also provided at the shaft end to connect with the roller arm. The roller arm is restrained by the pressure rail to prevent tipping, thus preventing the cart from tipping over. During discharge, the pressure rail restraining the roller arm bulges upwards, causing the roller arm to rise and tilting the cart to discharge the material.

[0003] As described above, the trolley shaft runs through the inner and outer rings of the slewing frame. Therefore, the bearing seats of the inner and outer rings of the slewing frame must maintain a high degree of coaxiality to connect the trolley shaft. Otherwise, the trolley will not rotate smoothly or may not rotate at all, making it impossible to unload materials and causing production accidents.

[0004] In the existing rotary frame manufacturing process, the bearing housing is usually machined first and then welded to the other parts of the rotary frame. When two bearing housings are installed in the rotary frame, there may be a large coaxiality deviation in the bearing holes of the two bearing housings. After multiple rotary frames are combined, a large cumulative error will be caused, which will affect the installation and movement of the trolley's rotating shaft and cause the trolley to not rotate smoothly. Summary of the Invention

[0005] Based on the above situation, the main objective of this invention is to provide a scribing and measuring device and a method for using the rotating body of an annular cooler, so as to solve the problem of excessive coaxiality deviation of the bearing holes drilled in the bearing seats of the inner and outer frames during the machining of the rotating frame.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0008] A rotating assembly, comprising a connecting end and a rotating end, wherein the connecting end is connected to the axis of the rotating frame, and the rotating end is capable of rotating relative to the connecting end with the axis of the rotating frame as the center.

[0009] A connecting rod is slidably connected to the rotating assembly along a first direction, wherein the first direction is the projection direction of the line connecting the connecting end and the rotating end on the plane where the rotating frame is located;

[0010] A scriber, which is mounted on the connecting rod.

[0015] Preferably, the central rotating column is vertically arranged, the rotating beam is perpendicular to the central rotating column, the lower end of the central rotating column is fixed to the axis of the rotating frame, and one end of the rotating beam is fixed with a bushing, which is rotatably connected to the central rotating column.

[0016] Preferably, the rotating assembly includes a rotating beam, one end of which is bent downward to form a connecting end rotatably connected to the axis of the rotating frame, and the connecting rod is slidably connected to the lower side of the rotating beam.

[0017] Preferably, it also includes columns;

[0018] The rotating end extends to the outside of the outer ring of the rotating frame, the column is vertically fixed to the rotating end, and the lower end of the column is connected to a wheel, the axis of which is in the same direction as the first direction.

[0019] Preferably, a connecting frame is fixed to the lower end of the connecting rod, the scriber passes through the connecting frame, and a bolt is threaded to one side of the connecting frame, the shank end of the bolt being able to press against the scriber.

[0020] Preferably, a slide rail is fixed below the rotating assembly, a slide block is connected to the slide rail, and the connecting rod is fixed below the slide block.

[0021] On the other hand, this application also provides a measurement and processing method for a scribing measuring device for a rotating body of an annular cooler. The steps using the aforementioned scribing measuring device for a rotating body of an annular cooler are as follows:

[0022] Step 1: According to the design drawings, weld the bearing housing with the unbored bearing hole and the rotary frame subunit together;

[0034] The present invention is described below based on embodiments, but the present invention is not limited to these embodiments. In the following detailed description of the present invention, some specific details are described in detail, but well-known methods, processes, procedures, and elements are not described in detail in order to avoid obscuring the essence of the present invention.

[0035] Furthermore, those skilled in the art should understand that the accompanying drawings provided herein are for illustrative purposes only and are not necessarily drawn to scale.

[0036] Unless the context explicitly requires it, the words "comprising," "including," and similar terms throughout the specification and claims should be interpreted as encompassing rather than being exclusive or exhaustive; that is, meaning "including but not limited to."

[0037] In the description of this invention, it should be understood that the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Furthermore, in the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0038] Reference Figure 1 This invention provides a scribing and measuring device for the rotating body of an annular cooler, used to scribble lines on the rotating frame 6, facilitating the machining of bearing holes with high coaxiality on the bearing seats 63 on the inner ring 61 and outer ring 62 of the rotating frame 6. It should be noted that the rotating frame 6 includes an inner ring 61 and an outer ring 62, which are connected as a whole by connecting bodies such as rods and plates. The annular rotating frame 6 is composed of multiple rotating frame 6 sub-units. In this application, "inner" refers to the position of the inner ring 61 of the rotating frame 6 near the axis of the rotating frame 6, while "outer" refers to the position of the outer ring 62 of the rotating frame 6 away from the axis of the rotating frame 6.

[0039] Reference Figure 2 The scribing and measuring device for the rotating body of the annular cooler provided in this application includes a rotating assembly 1, a connecting rod 2, and a scribing blade 3. The connecting rod 2 is mounted on the rotating assembly 1, and the scribing blade 3 is mounted on the connecting rod 2.

[0040] Specifically, the rotating assembly 1 includes a central rotating column 11 and a rotating beam 12. The central rotating column 11 is vertically arranged and coaxially arranged with the rotating frame 6. The lower end of the central rotating column 11 forms a connecting end 111, which is rotatably connected to the axis of the rotating frame 6, so that the central rotating shaft can rotate in place at the axis of the rotating frame 6.

[0041] The rotating beam 12 is a straight rod. The rotating beam 12 is fixed to the side of the central rotating shaft by a bushing, and the rotating beam 12 is set perpendicular to the central rotating column 11, so that the rotating beam 12 can extend in the horizontal direction. The end of the rotating beam 12 away from the central rotating column 11 forms a rotating end 121. When the central rotating shaft rotates, the rotating beam 12 can rotate around the central rotating shaft as the center of rotation, so that the rotating end 121 can rotate relative to the connecting end 111 with the axis of the rotating frame 6 as the center.

[0042] Link 2 is slidably connected to the lower side of rotating beam 12 along the first direction a. The scribing blade 3 is positioned below link 2, moving with it and contacting the rotating frame 6 to scribble lines on its surface. In this embodiment, since rotating beam 12 is a straight rod, and the first direction a is the extending direction of rotating beam 12, when rotating assembly 1 is stationary, link 2 slides along the first direction a, causing the scribing blade 3 to move radially along the rotating frame 6.

[0043] It should be noted that the shape of the rotating beam 12 is not necessarily a straight rod, and the first direction a is not necessarily the extension direction of the rotating beam 12. As long as the first direction a is the projection direction of the line connecting the connecting end 111 and the rotating end 121 on the plane where the rotating frame 6 is located, the connecting rod 2 can drive the scribing blade 3 to move in the radial direction of the rotating frame 6 when sliding.

[0044] Furthermore, it is understood that the composition and connection of the rotating assembly 1' are not limited to the forms described above. For example, refer to... Figure 3 In another embodiment, the lower end of the central rotating column 11' is fixed to the axial position of the rotating frame 6, and one end of the rotating beam 12' is sleeved on the central rotating column 11' through a bushing. This also satisfies the requirement that the rotating end 121' can rotate relative to the connecting end 111' with the axial center of the rotating frame 6 as the center.

[0045] Reference Figure 4 In another embodiment, the rotating assembly 1” only includes an integrally formed rotating beam 12”. The two ends of the rotating beam 12” are a connecting end 111” and a rotating end 121”, respectively. The connecting end 111” is bent downward and rotatably connected to the axis of the rotating frame 6. The rotating beam 12” can rotate directly on its own, so that the rotating end 121” can rotate relative to the connecting end 111” with the axis of the rotating frame 6 as the center.

[0046] In existing technologies, the bearing housing 63 is usually machined first and then installed into the rotating frame 6 subunit. This method will produce a large cumulative error after installing multiple bearing housings 63. Alternatively, the bearing housing 63 can be installed into the rotating frame 6 subunit without boring holes. In most cases, workers use a measuring ruler to draw lines for measurement, which has too much influence from human factors.

[0047] When using the scribing measuring device of this application to scribing the rotary frame 6, firstly, the bearing housing 63 is installed into a single rotary frame 6 subunit, and then multiple rotary frame 6 subunits are assembled to form a complete annular rotary frame 6. The axis of the rotary frame 6 is determined, and the central rotary column 11 is rotatably connected to this point. The rotating beam 12 is rotated to the position of the bearing housing 63, and the sliding connecting rod 2 is used to drive the scribing cutter 3 to move, so that the scribing cutter 3 can scribing the same direction of the inner ring 61 and outer ring 62 of the rotary frame 6, scribing in one go. Completed; After scribing, a dual-axis boring machine can be used between the inner ring 61 and the outer ring 62 of the rotary frame 6. The dual-axis boring machine first moves along the scribing direction to drill the first bearing hole, and then moves in the opposite direction to drill the second bearing hole. It can process and drill the inner and outer bearing holes at one time, and the two bearing holes have a high degree of coaxiality. This eliminates the cumulative error caused by the measurement error of a single rotary frame 6 subunit, and also ensures that the center line of the scribing bearing seat 63 passes through the axis of the rotary frame 6, ensuring that the trolley shaft can rotate smoothly without jamming.

[0048] It should be noted that when the central rotating column 11 rotates to the position where the scribing blade 3 needs to scribing, on the one hand, the rotating component 1 has a certain weight and does not rotate freely. It can maintain the position of the rotating beam 12 in the circumferential direction of the rotating frame 6 by its own weight; on the other hand, external positioning tools, such as positioning plates, can also be used to limit the position of the rotating beam 12 and prevent the rotating beam 12 from shaking.

[0049] Reference Figure 2 As one embodiment, the scribing and measuring device for the rotating body of the annular cooler also includes a positioning bearing 13. The positioning bearing 13 can be fixed at the axial position of the rotating frame 6. The lower end of the central rotating column 11 is fixed to the positioning bearing 13. In this embodiment, the positioning bearing 13 can maintain the stability of the rotating component 1 when it moves.

[0050] As one embodiment, the scribing and measuring device for the rotating body of the annular cooler also includes a column 4. The rotating end 121 located on the rotating beam 12 extends to the outside of the outer ring 62 of the rotating frame 6. The column 4 is vertically fixed to the rotating end 121. The column 4 is vertically arranged, and a rotatable wheel 41 is provided at the lower end of the column 4. The axis of the wheel 41 is in the same direction as the first direction a. When the rotating assembly 1 rotates, the wheel 41 can play a supporting role, so that the rotating assembly 1 can rotate stably.

[0051] Reference Figure 5 In one embodiment, a connecting frame 5 is fixed to the lower end of the connecting rod 2, and the scribing blade 3 passes through the connecting frame 5. A bolt 51 is threadedly connected to one side of the connecting frame 5, and the end of the bolt 51 can tighten the scribing blade 3. The height of the scribing needle can be adjusted by the bolt 51, thereby improving the applicability of the scribing and measuring device of the rotating frame 6 of the annular cooler.

[0052] In one embodiment, a slide rail 122 is fixed below the rotating beam 12. The slide rail 122 extends in the same direction as the rotating beam 12. A slide block 123 is slidably connected below the slide rail 122. The connecting rod 2 is fixed below the slide block 123, enabling the connecting rod 2 to slide stably along the radial direction of the rotating frame 6. It is understood that the sliding structure of the slide rail 122 and the slide block 123 is not limited, as long as a connection structure that can achieve sliding guidance is acceptable. This is prior art and will not be described in detail in this application.

[0053] This application also provides a measurement and machining method for the scribing measuring device for the rotating body of the annular cooler described above, the steps of which are as follows:

[0054] Step 1: According to the design drawings, weld the bearing housing 63 with the unbored bearing hole and the rotating frame 6 subunit together.

[0055] Step 2: Combine multiple slewing frame 6 sub-units to form a complete slewing frame 6, and determine the axis position of the slewing frame 6;

[0056] Step 3: Install the connecting end 111 of the rotating component 1 to the axial position of the rotating frame 6, rotate the rotating end 121 to the corresponding position of the bearing seat 63, slide the connecting rod 2 and the scribing blade 3, and scribing the inner ring 61 and outer ring 62 of the rotating frame 6 to draw the indexing lines.

[0057] After the above steps are completed, the scribing cutter 3 scribing index lines on the surfaces of the inner ring 61 and the outer ring 62 of the rotary frame 6, fixing the twin-axis boring machine between the inner ring 61 and the outer ring 62, and after clamping and fixing the boring machine, sliding along the extension direction of the indexing lines to machine bearing holes in the bearing seats 63 of the inner ring 61 and the outer ring 62 of the rotary frame 6 respectively, ensuring the coaxiality of the two bearing holes.

[0058] Those skilled in the art will understand that, without conflict, the above-mentioned preferred solutions can be freely combined and superimposed.

[0059] It should be understood that the above embodiments are merely exemplary and not restrictive. Various obvious or equivalent modifications or substitutions that can be made by those skilled in the art regarding the above details without departing from the basic principles of the present invention will be included within the scope of the claims of the present invention.
