[0002] In industrial production, the rotary kiln cylinder is one of the indispensable equipment, especially in the ceramic, cement, metallurgy and other industries, where it is widely used. The ends of the rotary kiln cylinder are usually provided with connection ends, through which they are connected to other equipment or structures. However, in actual operation, the end connection of the rotary kiln cylinder often faces many challenges.

[0003] First, due to the large weight and volume of the cylinder body, the traditional connection method usually requires the use of heavy equipment such as cranes for lifting and positioning, which not only increases the complexity and difficulty of the work, but also increases the working intensity of the crane and reduces work efficiency. Secondly, the traditional connection method often lacks a precise guiding mechanism, which leads to deviations during the connection process, affecting the stability and sealing of the connection. This may not only cause safety accidents, but also affect the normal operation of the rotary kiln cylinder and product quality. Therefore, a rotary kiln cylinder is proposed to solve the above-mentioned problems. Utility Model Content

[0025] See also Figure 1-3 A rotary kiln cylinder comprises a cylinder body 1, a connecting member 2 and a guide assembly, wherein the connecting member 2 is arranged outside the cylinder body 1 near one end, and a guide assembly is arranged outside the connecting member 2;

[0026] The guide assembly includes a motor 3, two rotating rods 4, two guide columns 5 and a guide block 6. The motor 3 is arranged on the connecting piece 2. The two rotating rods 4 and the guide columns 5 are distributed around the center and circumference of the top surface of the cylinder body 1. A rotating rod 4 is fixed to the output end of the motor 3 by bolts.

[0027] In this embodiment, the connecting member 2 is composed of a connecting ring 201 and two groups of connecting pins, the two groups of connecting pins are respectively a first connecting pin 202 and a second connecting pin 203 , and both groups of connecting pins are provided with four and are circumferentially distributed at the top and bottom of the outer side of the connecting ring 201 .

[0028] It should be noted that the connector 2 is composed of a connecting ring 201 and two sets of connecting feet. This design ensures that the connector 2 can be firmly installed on the outside of the cylinder body 1 and provides sufficient support points to fix the guide assembly. The two sets of connecting feet are respectively distributed circumferentially on the top and bottom of the outer side of the connecting ring 201, so that the entire connector 2 has a uniform force distribution, thereby improving the stability of the structure.

[0029] In this embodiment, the bottom of the motor 3 is plugged into a second connecting foot 203 and fixed by bolts. The top of the rotating rod 4 fixed by bolts to the output end of the motor 3 and the other rotating rod 4 and the two ends of the two guide columns 5 are rotatably connected to the two sets of connecting feet through bearings.

[0030] It should be noted that the bottom of the motor 3 is plugged into a second connecting foot 203 and then fixed with bolts. This fixing method ensures the stable operation of the motor 3 and simplifies the installation process. The motor 3 serves as a driving source and provides power for the entire guide assembly through the rotating rod 4 fixed with bolts at its output end.

[0031] In this embodiment, threads are provided on the outside of the two rotating rods 4 and the threads are in the same direction. The guide block 6 is composed of a guide seat 601 and a connecting cylinder 602 . The guide seat 601 is threadedly connected to the two rotating rods 4 .

[0032] It should be noted that the two rotating rods 4 are provided with threads on the outside and the threads are in the same direction. This design enables the rotating rod 4 to drive the guide seat 601 in the guide block 6 threadedly connected thereto to move along the axis direction of the rotating rod 4 when rotating. This movement method is accurate and reliable, ensuring that the guide block 6 can accurately move to the predetermined position.

[0033] In this embodiment, the guide seat 601 is also plugged into the two guide columns 5 , and the inner wall of the connecting column 602 is arranged in two layers from top to bottom, one layer is arranged on the outside of the end of the cylinder body 1 , and the other layer is arranged on the outside of the connecting ring 201 .

[0034] It should be noted that the guide block 6 is composed of a guide seat 601 and a connecting cylinder 602. This design enables the guide block 6 to tightly cover the end of the cylinder body 1 and the connecting ring 201. The two-layer design of the inner wall of the connecting cylinder 602 is respectively attached to the outer side of the cylinder body 1 and the connecting ring 201, further enhancing the tightness and stability of the connection.

[0035] In this embodiment, four circumferentially distributed moving grooves 603 are formed on the outer side of the connecting cylinder 602 . The width of the moving groove 603 is greater than the width of the first connecting pin 202 . The first connecting pin 202 is located inside the moving groove 603 .

[0036] It should be noted that the four moving grooves 603 opened on the outside of the connecting cylinder 602 allow the first connecting leg 202 to move freely inside. This design not only facilitates the movement of the guide block 6, but also facilitates the preliminary welding and fixing of the end of the cylinder body 1. The width of the moving groove 603 is greater than the width of the first connecting leg 202, ensuring the smoothness of the first connecting leg 202 during movement.

[0037] Working principle:

[0038] When it is necessary to connect the end of the cylinder body 1, the motor 3 starts and drives the rotating rod 4 fixed with the output end bolt to rotate. Since the two rotating rods 4 are provided with threads on the outside and the thread directions are consistent, when one rotating rod 4 rotates, the other rotating rod 4 will also rotate synchronously. The rotation of the rotating rod 4 will drive the guide seat 601 in the guide block 6 threadedly connected thereto to move along the axial direction of the rotating rod 4. The guide seat 601 is simultaneously plugged with the two guide columns 5 to ensure stability during the movement. The connecting column 602 is another part of the guide block 6, and its inner wall is tightly fitted to the outer side of the end of the cylinder body 1 and the outer side of the connecting ring 201, ensuring that the guide block 6 can tightly cover the cylinder body 1 and the connecting ring 201. During the movement of the guide block 6, since the width of the moving groove 603 is greater than the width of the first connecting leg 202, the first connecting leg 202 can move freely inside the moving groove 603. At the same time, the setting of the moving groove 603 is also convenient for preliminary welding and fixing of the end of the cylinder body 1.

[0039] Beneficial effects:

[0040] The rotary kiln cylinder drives the rotating rod 4 fixed with the output end bolts to rotate by starting the motor 3. Since the two rotating rods 4 are provided with threads in the same direction on the outside, they will rotate synchronously, thereby driving the guide seat 601 in the guide block 6 threadedly connected thereto to move along the axis direction of the rotating rod 4. The guide seat 601 is plugged with the two guide columns 5 at the same time, ensuring the stability during the movement. The connecting column 602 is a component of the guide block 6, and its inner wall is tightly fitted to the outer side of the end of the cylinder body 1 and the outer side of the connecting ring 201, so that the guide block 6 can tightly cover the two. In addition, the four moving grooves 603 opened on the outside of the connecting column 602 allow the first connecting foot 202 to move freely inside, which is not only convenient for the movement of the guide block 6, but also convenient for the preliminary welding and fixing of the end of the cylinder body 1. This design reduces the demand for the use of heavy equipment such as cranes, reduces the work intensity, improves the work efficiency, and also ensures the stability and reliability of the connection.
