Description

Technical Field

[0001] The invention relates to the technical field of sintering cooling equipment, and in particular to a split rocker arm device and a pellet ring cooler. Background Art

[0002] Sintering production is the first process in the steel industry. During the sintering process, the ring cooler is the most important equipment in the sintering system. Its normal operation will play a key role in the output and quality of the product.

[0003] The pelletizing ring cooler plays a role in cooling and continuously transporting high-temperature sintered ore in the entire sintering process. In the pelletizing ring cooler, the rocker device is an important device to realize the horizontal operation of the trolley and the overturning unloading. The rocker devices commonly used in the market are usually composed of a roller arm and an eccentric wheel structure. The eccentric wheel is locked on the eccentric shaft by a locking mechanism. When the trolley is uneven, the locking mechanism is released, and the position of the eccentric wheel is adjusted by rotating the eccentric shaft, so that the trolley can be leveled. However, the structure of the existing rocker device is extremely complicated. The entire roller arm is usually twisted into a special-shaped structure, and the upward angle of the roller arm causes the keyway of the trolley shaft seat and the keyway of the shaft sleeve to form a certain angle, which is extremely inconvenient for manufacturing and processing, and the manufacturing accuracy is also difficult to control. Furthermore, in order to facilitate the installation of the locking mechanism and the locking of the eccentric shaft, the sleeve mounted on the eccentric shaft not only needs to be cast with a protruding boss to realize the bolt locking mechanism, but the sleeve also needs to be slit to facilitate the removal and installation of the eccentric shaft. At the same time, a chuck locking mechanism must be designed at the outer end of the eccentric shaft to prevent the shaft from loosening. The chuck locking mechanism is extremely complicated, which results in the structural design of the rocker arm device being very troublesome, with high forging cost, many defects, high risks, and extremely inconvenient installation and adjustment. Summary of the invention

[0032] The following embodiments of the present invention are described in further detail in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0033] like Figures 1 to 6 As shown, an embodiment of the present invention provides a split rocker arm device (the embodiment of the present invention is referred to as a "rocker arm device"), and provides a pellet ring cooler based on the rocker arm device.

[0034] like Figure 1 As shown, the specific operation process of the pelletizing ring cooler described in the embodiment of the present invention is as follows: driven by the driving mechanism, the trolley 3 of the pelletizing ring cooler is connected to the ring track under the rotating frame through the rocker device 4, and performs horizontal circular motion on the supporting roller. The ring track specifically includes a continuously arranged feeding cooling rail 11, a discharging rail 12 and a reset rail 13. The trolley 3 passes through the feeding cooling rail 11 of the ring track, and the rocker device 4 is pressed by the feeding cooling rail 11 to maintain the horizontal working state of the trolley 3; after the sintered ore on the trolley 3 is cooled, the rocker wheel of the rocker device 4 begins to rise along the discharging rail 12, and the bottom plate of the trolley 3 slowly tilts with the rotation of the rocker device 4 under the action of the trolley 3's own weight and the gravity of the material, and the cooled sintered ore is unloaded to the discharge chute ( Figure 1After the trolley 3 is unloaded, it begins to reset with the help of the reset roller 2, and the rocker device 4 also descends along the unloading pressure rail 12 to the reset pressure rail 13, forcing the trolley 3 to rotate in the opposite direction until it is leveled, so as to enter the feeding cooling pressure rail 11 again, thereby realizing the whole process of cooling the high-temperature sintered ore by the ring cooler. It can be seen that the rocker device 4 is connected between the trolley and the ring track, and is the key structure for changing the posture of the trolley 3.

[0035] like Figure 2 and Figure 3 As shown, the rocker device 4 includes a load-bearing beam 42 and a rocker wheel seat 44. A mounting surface is constructed on one side of the rocker wheel seat 44, and the rocker wheel seat 44 is detachably connected to one end of the load-bearing beam 42 through the mounting surface, and a shim group for adjusting the rocker wheel elevation is installed between the mounting surface and the load-bearing beam 42. During the operation of the pellet ring cooler, if the trolley 3 is uneven or the posture is incorrect, the posture adjustment of the trolley 3 can be quickly achieved by changing the overall size of the shim group, which is extremely convenient to operate and will not cause adverse effects on the overall operation of the pellet ring cooler.

[0036] Based on the above structure, the other end of the load-bearing beam 42 is used to connect the trolley 3. The rocker wheel seat 44 is mounted on one end of the rocker wheel shaft 46, and the other end of the rocker wheel shaft 46 is connected to the rocker wheel body 47. The rocker wheel body 47 can be pressed onto the circular track, thereby driving the trolley 3 to move along the circular track and driving the trolley 3 to adjust its posture in time during the movement of the trolley 3.

[0037] Compared with the prior art, the rocker arm device 4 is simpler in structure by setting the rocker arm wheel seat 44 and the bearing beam 42 as a detachably connected split structure, which is convenient for operation, installation, adjustment and manufacturing, and greatly reduces the production and maintenance costs of the pelletizing ring cooler. In addition, in actual installation and application, the rocker arm device 4 can be applied to ring coolers of various specifications by changing the structural parameters of the rocker arm wheel seat 44 and the bearing beam 42 as needed, effectively expanding the application range of the rocker arm device 4.

[0038] It is understandable that the shim set installed between the mounting surface of the rocker wheel seat 44 and the load-bearing beam 42 includes at least one adjustment shim 43. By changing the thickness of a single adjustment shim 43 and / or increasing or decreasing the number of adjustment shims 43, the height of the gap between the mounting surface and the load-bearing beam 42 can be quickly and conveniently adjusted, thereby adjusting the rocker wheel elevation, and then changing the size of the above gap more efficiently and accurately, thereby improving the efficiency and accuracy of the posture adjustment of the trolley 3.

[0039] It can be understood that a connecting sleeve 41 is fixedly connected to one end of the load-bearing beam 42 away from the rocker wheel seat 44, and the connecting sleeve 41 is used to connect the trolley 3. The axial direction of the rocker wheel shaft 46 and the axial direction of the connecting sleeve 41 are set at a preset angle α, and the size of the preset angle α can be changed according to actual needs, so that the rocker device 4 can adapt to the angle requirements of the rocker wheel body 47 of the ring cooler of different specifications.

[0040] It is understandable that the load-bearing beam 42 described in the embodiment of the present invention can be a straight beam structure. Compared with the prior art, the load-bearing beam 42 does not need to be set as an eccentric shaft, which effectively reduces the difficulty of production and manufacturing, and can reduce production costs and improve manufacturing accuracy.

[0041] In some embodiments, Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, the rocker wheel seat 44 includes a seat body 441, an axial hole 442 and a flange 443. The above-mentioned mounting surface is constructed on one side of the seat body 441, and the mounting surface is preferably constructed as a plane so as to match the surface of the load-bearing beam 42. The mounting surface on the seat body 441 is extended to both sides to construct flanges 443, so as to expand the area of ​​the mounting surface by using the flanges 443, so as to facilitate the close installation between the rocker wheel seat 44 and the load-bearing beam 42, and the adjustment and control of the thickness of the gasket between the mounting surface and the load-bearing beam 42 is more accurate. The position of the seat body 441 facing away from the mounting surface is constructed with an axial hole 442 that runs through the seat body 441, and the mounting surface is arranged parallel to the central axis of the axial hole 442, and the axial hole 442 is sleeved on the outside of one end of the rocker wheel shaft 446 to ensure that the axial direction of the rocker wheel shaft 446 can be parallel to the mounting surface, to ensure the stability of the moment during the operation of the rocker wheel, and to improve the structural strength.

[0042] In some embodiments, the flange 443 is connected to the load-bearing beam 42 via a fastener 45. The fastener 45 is preferably a locking bolt that penetrates the flange 443 and is fastened in the load-bearing beam 42. Preferably, the fasteners 45 are arranged in pairs on the flanges 443 on both sides of the rocker arm wheel seat 44, and preferably the number of pairs of fasteners 45 is one pair or more, so as to improve the connection strength and connection stability between the rocker arm wheel seat 44 and the load-bearing beam 42.

[0043] It is understandable that the fastener 45 can also be a clamping plate or a pin, that is, as long as the rocker wheel seat 44 and the load-bearing beam 42 are detachably connected.

[0044] In one embodiment, the rocker arm wheel seat 44 is constructed as an integral shaft seat structure. That is, as shown in FIG. 5 , the distance between the mounting surface and the central axis of the shaft hole 442 is greater than the radius of the shaft hole 442 to ensure that the mounting surface and the shaft hole 442 are not connected, to ensure the structural strength of the seat body 441, and to avoid wear between the rocker arm wheel shaft 446 set in the shaft hole 442 and the surface of the load-bearing beam 42.

[0045] In another embodiment, the rocker arm wheel seat 44 can also be constructed as a split shaft seat structure. Figure 6 As shown, the distance between the mounting surface and the central axis of the shaft hole 442 is less than or equal to the radius of the shaft hole 442, so that at least a portion of the inner wall of the shaft hole 442 passes through the mounting surface, that is, when the seat body 441 is attached and fixed to the surface of the load-bearing beam 42 through the mounting surface, the rocker wheel shaft 446 is in contact with the surface of the load-bearing beam 42. This structural setting can reduce the thickness of the rocker wheel seat 44, so that the rocker device 4 has a smaller occupied space, which can be more powerful and space-efficient when there is insufficient space in the annular cooler.

[0046] In some embodiments, the mounting structure of the rocker wheel seat 44 connected to the end of the load-bearing beam 42 through the mounting surface can further be at least two mounting structures. Figure 3 As shown, the rocker wheel seat 44 is connected to the side of the load-bearing beam 42 through the mounting surface. In another embodiment, as Figure 4 As shown, the rocker arm wheel seat 44 is connected to the end surface of the load-bearing beam 42 through the mounting surface. The specific mounting position of the mounting surface of the rocker arm wheel seat 44 on the load-bearing beam 42 can be determined according to the positional relationship between the rocker arm wheel shaft 46 and the trolley 3 in the annular cooler. The above two mounting structures can effectively expand the installation and use range of the rocker arm device 4, so that the rocker arm device 4 can be applied to annular coolers of more specifications.

[0047] like Figure 1 As shown, the operation process of the pellet ring cooler proposed in the embodiment of the present invention is as described above, which will not be repeated here. The pellet ring cooler specifically includes the rocker device 4 as described above. By setting the rocker device 4, the pellet ring cooler has all the advantages of the rocker device 4, and the specific advantages will not be repeated here.
