Description

Technical Field

[0001] The utility model belongs to the technical field of roller equipment used in metal smelting, cement, chemical and other industries, and particularly relates to a roller ring installation structure in rotary long cylindrical equipment. Background Art

[0002] Rotating long cylindrical equipment is generally installed at an angle on a base platform, and relies on gear meshing transmission to drive the cylinder to rotate. Due to the long cylinder, a roller and a supporting roller assembly are required to support the cylinder and assist in its rotation. One existing roller installation structure is a roller sleeved on the outside of the cylinder, with hook-shaped pads evenly distributed in the circumferential direction between the cylinder and the roller. One side of the roller is fixed by the hook-shaped pad, and the other side is fixed by a pressure plate block bolt. In order to facilitate the installation of the roller, the gap between the pad and the roller in this structure is relatively large; another roller installation structure is also a roller sleeved on the outside of the cylinder, with flat pads and an inclined iron structure evenly distributed in the circumferential direction between the cylinder and the roller. The roller is fixed to the cylinder by this structure, but after a period of actual production operation of the equipment, the inclined iron becomes loose due to slight vibration of the equipment. Both of the above structures are prone to cause problems such as loosening between the cylinder ring and the cylinder, and the cylinder losing its rotation during actual production operation, thereby affecting the operating efficiency of the equipment. Summary of the Invention

[0003] The utility model aims to solve the above problems and provides a new roller ring installation structure which can ensure the strength of the rotating cylinder, solve the problems of loose sleeve between the existing roller ring and the cylinder and the cylinder losing rotation, and ensure the operating efficiency of the whole equipment.

[0015] The utility model includes a cylindrical body 5 and a rolling ring 1, and is characterized in that: the cylindrical body 5 is composed of a plurality of cylinder segments 8, and the rolling ring 1 is arranged at the joint between two cylinder segments 8; the rolling ring 1 and two adjacent cylinder segments 8 are connected as one by welding and / or mechanical connection.

[0016] By placing the roller ring 1 at the joint between the two cylinder sections 8 and using welding and / or mechanical connection, the cylindrical body 5 and roller ring 1 are integrated. This structure effectively avoids the problems of loosening and loss of the traditional roller ring 1, improves the connection strength between the roller ring 1 and the cylinder, and improves the overall operational stability of the equipment, fundamentally reducing equipment failures caused by loose roller ring 1.

[0017] One side of the roller ring 1 is connected to the outer surface of one cylinder segment 8 by fillet welding, and the other side of the roller ring 1 is connected to the outer surface of the other cylinder segment 8 by fillet welding; the two cylinder segments 8 are connected at the inner surface joint by a U-shaped weld.

[0018] The corner welding connection between the rolling ring 1 and the outer surfaces of the two cylinder segments 8 further enhances the fixing strength of the rolling ring 1 and the cylinder segments 8, ensuring their shock resistance during operation; the U-shaped weld connection method is adopted at the inner surface joints to enhance the structural rigidity between the cylinder segments 8, thereby improving the reliability of equipment operation.

[0019] The inner surface of the rolling ring 1 is provided with two connecting holes corresponding to the two cylinder sections 8 , and the two cylinder sections 8 are provided with through holes corresponding to the connecting holes, and the through holes and the connecting holes are connected by a pin 9 .

[0020] The connection hole provided on the inner surface of the rolling ring 1 is connected to the through hole on the cylinder segment 8 through the pin 9 to form a mechanical connection, which improves the connection firmness between the rolling ring 1 and the cylinder segment 8 and prevents the rolling ring 1 from loosening or shifting due to vibration or force during long-term operation.

[0021] One side of the rolling ring 1 is connected to the outer surface of a cylinder segment 8 by fillet welding, and the other side of the rolling ring 1 is connected to the outer surface of the other cylinder segment 8 by fillet welding; the two cylinder segments 8 are connected at the inner surface joint by a U-shaped weld; the inner surface of the rolling ring 1 is provided with two connecting holes corresponding to the two cylinder segments 8, and the two cylinder segments 8 are provided with through holes corresponding to the connecting holes, and the through holes and the connecting holes are connected by a pin 9; the length of the pin 9 is greater than the depth of the connecting hole and less than the sum of the depths of the connecting hole and the through hole; the pin 9 passes through the through hole and is inserted into the bottom of the connecting hole, so that a groove is formed at the through hole on the inner surface of the cylinder segment 8, and the groove is closed by welding.

[0022] By combining mechanical connection with welding, a multi-level connection structure is formed between the roller ring 1 and the cylinder segment 8. The length of the pin 9 is designed so that it can be firmly inserted into the through hole and the connection hole, and the groove is closed by welding, further improving the connection strength.

[0025] Two sets of rollers 1 and a large gear 3 are mounted on the cylindrical body 5, the main component of a rotating long cylindrical device. The cylindrical body 5 is supported by two supporting rollers 2 mounted on an inclined base platform 7. A transmission 6 drives the rotation of the small gear 4, which in turn meshes with the large gear 3 to drive the cylindrical body 5, thereby achieving functions such as mixing and drying the material inside the cylindrical body. The utility model integrates the rollers 1 and the cylindrical body 5 into a single unit through the innovative design of the mounting structure of the rollers 1 and the cylindrical body 5, effectively eliminating problems such as loosening of the rollers 1 and the cylindrical body 5 and loss of rotation of the cylindrical body 5.
