Description

Technical Field

[0001] The utility model relates to the technical field of reset wheels for annular coolers, in particular to a reset wheel device for annular coolers which is convenient for maintenance and replacement. Background Art

[0002] In recent years, with the advancement of technology and the continuous improvement of energy-saving and environmental protection requirements, the cooling equipment of newly built sintering plants generally adopts water-sealed ring coolers, and most of the original traditional rubber-sealed or mechanical-sealed ring coolers have also been transformed into water-sealed ring coolers. Therefore, water-sealed ring coolers are widely used in steel enterprises.

[0003] The reset wheel is a key component of the water-sealed annular cooler. After the annular cooler trolley fully loaded with sintered ore is unloaded in the unloading area, it needs to be reset by the reset wheel. The bottom plate of the empty trolley rolls forward along the wheel surface of the reset wheel and is lifted upward to complete the bottom plate reset. When the reset wheel has a bearing failure or other failures, the bottom plate of the trolley after unloading will not be able to be reset normally, which will cause other accidents.

[0004] The reset wheel is installed in the unloading bucket of the ring cooler. The gap between the upper part and the bottom plate of the trolley is 0-100mm, and the distance between the outer side and the water tank under the outer ring of the ring cooler is only about 150mm. The operating space is limited, and the weight of the reset wheel plus the base is 780Kg, which makes replacement extremely inconvenient. Figure 6 shown. Utility Model Content

[0005] The purpose of the utility model is to solve the problems raised in the above-mentioned background technology and to provide a ring cooler reset wheel device which is easy to repair and replace.

[0006] The specific technical scheme of the utility model is as follows: a reset wheel device for a ring cooler which is easy to repair and replace, comprising a mounting seat, a support shaft mounted on the mounting seat, a reset wheel mounted on the support shaft, a bearing mounted between the reset wheel and the support shaft, the mounting seat being composed of a fixed bracket and a movable bracket, the fixed bracket and the movable bracket being both L-shaped brackets, a bolt hole being provided at the bottom of the fixed bracket, a connecting hole corresponding to the bolt hole being provided at the bottom of the movable bracket, an axial hole being provided at the same position on the upper ends of the fixed bracket and the movable bracket, and the axial hole matching the support shaft.

[0007] Preferably, a positioning sink is provided at the bottom of the fixed bracket, and the positioning sink is used to position the movable bracket.

[0008] Preferably, a locking plate is installed at the upper end of the movable bracket outside the shaft hole, and the locking plate is connected to the end surface of the supporting shaft by screws.

[0009] Preferably, a limit plate is installed on the fixed bracket outside the shaft hole, and a limit groove is provided at the other end of the support shaft corresponding to the limit plate.

[0010] Preferably, a lubricating oil hole is provided at the center of one end of the support shaft facing the movable bracket, the inner end of the lubricating oil hole extends to the bearing, and the outer end of the lubricating oil hole is connected to an oil pipe.

[0011] The beneficial effects of the utility model are as follows: 1. The mounting seat is set to a split type, which is easy to disassemble and assemble, so that only the wheel body and the movable bracket part can be disassembled and assembled, and there is no need to disassemble and assemble the fixed bracket; 2. The fixed bracket does not need to be disassembled and assembled, and there is no need to reposition it, which saves the adjustment time for positioning and alignment, and shortens the replacement operation time; 3. The locking plate and the oil pipe are both set at one end of the support shaft facing the movable bracket. Compared with the other end which is only 150mm away from the water tank under the outer ring of the annular cooler, it has a larger operating space and is more convenient for disassembly and assembly operations or filling lubricating oil through the oil pipe.
