Description

Technical Field

[0001] This utility model relates to the field of fastener technology, specifically to a fastening assembly for ball mill bolts. Background Technology

[0002] Ball mills are widely used crushing and grinding equipment in industries such as mineral processing, metallurgy, thermal power generation, and cement manufacturing. The working part of a ball mill is a rotating cylindrical body. The inner wall of the cylindrical body is lined with manganese steel plates that have high wear resistance and toughness. The liner plates are fastened to the outer shell with bolts and nuts. During operation, the ball mill contains wear-resistant steel balls and the material to be crushed. As the cylinder rotates, the steel balls and the material constantly collide and rub against each other, crushing and grinding the material into powder. Therefore, ball mills operate under conditions of strong vibration, and the liner plates are directly subjected to impact and wear. The bolts and nuts used to fasten the liner plates are very prone to loosening and slippage under strong vibration, causing powder leakage and even bolt breakage, leading to equipment malfunctions.

[0003] For example, Chinese patent CN213254829U discloses a ball mill rubber liner. This assembly includes a ball mill drum, a simple liner, a limiting block, a pressure strip assembly, and a T-bolt assembly. The pressure strip assembly includes a first rubber block, a support frame, a first metal plate, an outer metal frame, a second rubber block, a first connecting post, a second metal plate, threaded countersunk holes, and fastening bolts. Several second connecting posts are fixed to the surface of the outer metal frame, which is located inside the second rubber block. The second connecting posts penetrate the second rubber block and overlap its surface. Springs are fitted around the periphery of the fastening bolts. The T-bolt assembly includes a bolt post and a slider. The ball mill rubber liner provided by this invention has strong impact resistance, avoiding the difficulty of replacing the liner after deformation. It also allows for targeted replacement of specific parts of the liner, increasing its utilization rate and making replacement convenient and practical. However, in this solution, the bolt's anti-loosening effect is generally poor; the bolt may loosen under vibration. Therefore, we propose a fastening assembly for ball mill bolts. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a fastening assembly for ball mill bolts, solving the problems mentioned in the background art.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A fastening assembly for ball mill bolts, comprising:

[0007] A base, the top surface of which is connected to a bolt body;

[0008] Two sliding grooves are formed on the top surface of the base;

[0009] A fastening assembly is disposed inside the slide groove to limit the bolt body. The fastening assembly includes a positioning block disposed inside the slide groove. A rotating rod is rotatably connected to the top surface of the positioning block. A limit block is provided at one end of the rotating rod. A connecting groove is formed on the top surface of the limit block. A bearing is connected inside the connecting groove. One end of the rotating rod is connected to the inner ring of the bearing. A limit groove is formed on the bottom surface of the limit block. The limit groove has the same size as the bolt body.

[0010] By adopting the above technical solution and setting fastening components, when using the ball mill, after the operator installs the bolts, the positioning block is pushed to slide into the inside of the groove, so that the positioning block abuts against the end of the groove, completing the initial installation of the positioning block. Then, by rotating the rotating rod, the limiting block is moved vertically, so that the limiting block is close to the bolt body on the base. The limiting groove fits with the top of the bolt body, achieving the purpose of fastening the limiting bolt body.

[0011] Preferably, the fastening assembly further includes:

[0012] A top groove is formed on the inner top surface of the limiting groove, and multiple springs are connected inside the top groove, with one end of each spring connected to a top block.

[0013] By adopting the above technical solution and setting a top block, when the limiting block is in contact with the bolt body during use, the top of the bolt body will push the top block to move, causing the top block to compress the spring. When the limiting block moves to the limit position, the spring will release the absorbed potential energy and push the top block to move, so that the top block applies pressure to the bolt body, preventing the bolt body from loosening due to the vibration of the ball mill and improving the stability of the fastening.

[0014] Preferably, the top surface of the rotating rod is provided with a plurality of fixing holes, and the top surface of the positioning block is provided with a plurality of fixing grooves. The positions of the fixing holes correspond to the positions of the fixing grooves. A limiting screw is rotatably connected inside the fixing hole, and the limiting screw extends through the fixing hole into the interior of the fixing groove.

[0015] By adopting the above technical solution and setting a limit screw, after the limit block is installed, the operator inserts the limit screw into the fixing hole and then rotates the limit screw to fix it in the fixing groove, thereby achieving the purpose of fixing and limiting the rotating rod and preventing the rotating rod from being loosened by vibration.

[0016] Preferably, a sealing groove is provided on the top surface of the base, and a sealing gasket is connected inside the sealing groove.

[0017] By adopting the above technical solution and setting a sealing gasket, the top and bottom surfaces of the bolt body and the top surface of the base are buffered and fitted together during application, avoiding gaps between the bolt body and the base and improving practicality.

[0018] Preferably, the bottom surface of the positioning block is connected to two sliders, and the sliders are movably fitted together with the groove.

[0019] By adopting the above technical solution and setting a slider, the slider is engaged with the slide groove during use, which makes it convenient for operators to push the positioning block to move and improves its practicality.

[0020] Preferably, the positioning block has side grooves on its left and right sides, and the top surface of the base has two positioning holes. The positioning holes are connected to positioning screws, which pass through the slider and extend into the base.

[0021] By adopting the above technical solution and setting a positioning screw, after the positioning block is installed in place, the operator can rotate the positioning screw, which rotates through the positioning hole and extends into the interior of the base to achieve the purpose of fixing and limiting the positioning block.

[0022] In summary, the present invention has the following main advantages:

[0023] By setting up a fastening assembly, during use, after the operator installs the bolts of the ball mill, they push the positioning block to slide it into the groove, making the positioning block abut against the end of the groove, completing the initial installation of the positioning block. Then, by rotating the rotating rod, the rotation of the rotating rod drives the limiting block to move vertically, so that the limiting block is close to the bolt body on the base. Through the limiting groove, it fits against the top of the bolt body, achieving the purpose of fastening and limiting the bolt body. By setting up a top block, during use, when the limiting block is in contact with the bolt body, the top of the bolt body will push the top block to move, causing the top block to compress the spring. When the limiting block moves to the limit position, the spring will release the absorbed potential energy, pushing the top block to move, so that the top block applies pressure to the bolt body, preventing the bolt body from loosening due to the vibration of the ball mill, and improving the stability of the fastening.

[0024] By setting a limit screw, after the limit block is installed, the operator inserts the limit screw into the fixing hole and then rotates the limit screw to fix it in the fixing groove, thereby achieving the purpose of fixing and limiting the rotating rod and preventing the rotating rod from being loosened by vibration.
