Description

Technical Field

[0001] This utility model relates to the field of cement production technology, and more specifically, it relates to a cement mill support mechanism for cement production. Background Technology

[0002] In the cement production process, the cement mill is an important key piece of equipment, responsible for grinding the raw materials. Because the cement mill is subjected to a large load during operation, especially when the mill cylinder is rotating, displacement or deviation may occur.

[0003] Therefore, the support system of the mill is required to have sufficient strength and stability to ensure the long-term efficient operation of the equipment. In the existing support system, the bottom of the mill cylinder is usually supported only. Although it can withstand a certain gravity load, it cannot effectively restrict or support the two sides of the mill cylinder. This design has certain limitations and cannot guarantee that the mill cylinder will not shake or shift abnormally under high load or vibration conditions. Utility Model Content

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, the present invention provides a support mechanism for a cement mill in cement production, which has the following advantages:

[0017] 1. This device significantly improves the stability of the cement mill cylinder by providing multi-directional support and restraint. Multiple support rollers on the mounting frame bear the weight load at the bottom of the mill cylinder. At the same time, the insertion holes and rods on the support plate add additional support and restraint functions on both sides of the mill cylinder. The installation of casters ensures the free movement of the mill cylinder in all directions. The precise fit between the fixed plate and the support plate can effectively reduce the vibration generated during high-speed operation of the mill, thereby improving the stability of the entire device and avoiding the shortcomings of relying solely on bottom support.

[0018] 2. This device also achieves precise positioning and adjustment functions. Through the combined design of the insertion rod, fixing sleeve and positioning rod, it can ensure accurate docking and fixation of the device during installation, avoiding the error problems existing in traditional support methods. In particular, with the cooperation of the fixing plate and the support plate, the positioning groove and positioning plate ensure the stable position of the mill cylinder throughout the working process, reducing mill offset or imbalance caused by improper installation or uneven support, thereby improving the working efficiency and safety of the cement mill.

[0019] 3. By rotating the rotating sleeve, the limiting rod is disengaged from the limiting hole, allowing the support structure to be easily released from its fixed position. This enables the mill cylinder to be quickly disassembled and reinstalled. The synergistic effect of the return spring and the tension spring makes the unlocking operation easier, avoiding the trouble of using complex tools or excessive manual operation required in traditional support mechanisms. This design not only improves the efficiency of maintenance and repair but also reduces equipment downtime and improves the overall operating efficiency of the production line.

[0030] A rotating sleeve 17 is rotatably mounted on the outer wall of the fixed sleeve 11. A mounting block 18 is fixedly mounted on the outer wall of the rotating sleeve 17. Multiple sets of mounting blocks 18 are distributed on the outer wall of the rotating sleeve 17, and each set has a limiting rod 19 fixedly mounted on its outer wall. A longitudinal rod 20 is fixedly mounted on the outer wall of the limiting sleeve 16. Multiple sets of longitudinal rods 20 are provided, and each set has a limiting hole 21 on its outer wall. This design, through the cooperation of the rotating sleeve 17 and the limiting rods 19, enables precise control of the rotating sleeve 17, ensuring appropriate rotational limitation during operation and guaranteeing the system's accuracy and stability.

[0031] The top of the insertion rod 7 is provided with a positioning hole 22, and the inner wall of the fixing sleeve 11 is fixed with a positioning rod 23. Both the positioning hole 22 and the positioning rod 23 are set as polygons. The polygonal design of the positioning hole 22 and the positioning rod 23 makes the connection between the insertion rod 7 and the fixing sleeve 11 more precise, preventing loosening or deviation caused by installation errors.

[0032] The outer wall of the fixed sleeve 11 is provided with a movable groove 24. Multiple movable grooves 24 are provided and are slidably connected to multiple sets of sliders. The top surfaces of multiple sets of push blocks 15 are all set to be arc-shaped. The cooperation between the movable groove 24 and the slider can keep the components running smoothly when sliding. The arc-shaped push block 15 design helps to reduce friction, thereby improving the stability and efficiency of the movement.

[0033] A reset spring 25 is provided between the limiting sleeve 16 and the fixing sleeve 11. Multiple sets of reset springs 25 are provided.

[0037] In this embodiment, during use, the mill cylinder 2 is placed on the support roller 4, then the universal wheel 10 abuts against the outside of the mill cylinder 2, the positioning plate 31 provided on the bottom surface of the fixing plate 8 is inserted into the positioning groove 32, then the insertion rod 7 is inserted into the insertion rod 7 and the fixing plate 8, then the fixing sleeve 11 is inserted into the top of the insertion rod 7, and the positioning rod 23 is positioned and inserted into the positioning hole 22, then the positioning rod 23 abuts against the abutment plate 28 and squeezes the compression spring 27, and then pushes... The movable limiting sleeve 16 abuts against the top of the multiple sets of push blocks 15, causing the multiple sets of push blocks 15 to push the slide rod 12 to slide and push the locking block 13 to engage in the slot 14. When the limiting sleeve 16 slides to the bottom, the multiple sets of limiting holes 21 are parallel to the limiting rod 19. Rotating the rotating sleeve 17 drives the multiple sets of mounting blocks 18 to rotate, thereby pushing the multiple sets of limiting rods 19 to be inserted into the limiting holes 21 to fix the limiting sleeve 16, thus completing the fixation of the fixing plate 8. The universal wheel 10 limits the outer wall of the mill cylinder 2.

[0038] More specifically, when it is necessary to release the limiting position of the mill cylinder 2, rotating the rotating sleeve 17 drives multiple sets of limiting rods 19 to disengage from the limiting hole 21, releasing the fixing of the limiting sleeve 16. Multiple sets of reset springs 25 push the limiting sleeve 16 to release the contact with multiple sets of push blocks 15. Multiple sets of tension springs 26 pull the locking block 13 to disengage from the locking groove 14. At the same time, the locking block 13 pushes the sliding rod 12 and causes the push block 15 to slide along the movable groove 24, releasing the contact with the insertion rod 7. The compression spring 27 resets and pushes the abutment plate 28. The abutment plate 28 abuts against the positioning rod 23 and pushes the insertion rod 7 to disengage from the fixing sleeve 11 and the insertion hole 6, completing the unlocking of the fixing plate 8.

[0039] In summary, during the use or operation of the overall equipment: When in use, place the mill cylinder 2 on the support roller 4, then abut the universal wheel 10 against the outside of the mill cylinder 2. Insert the positioning plate 31, located on the bottom surface of the fixing plate 8, into the positioning groove 32. Then, insert the insertion rod 7 into the fixing plate 8, and then insert the fixing sleeve 11 into the top of the insertion rod 7. Position the insertion rod 23 into the positioning hole 22, and then abut the positioning rod 23 against the abutment plate 28, compressing the compression spring 27. Press down, and then push the limiting sleeve 16 against the top of the multiple sets of push blocks 15, so that the multiple sets of push blocks 15 push the slide rod 12 to slide and push the locking block 13 to engage in the slot 14. When the limiting sleeve 16 slides to the bottom, the multiple sets of limiting holes 21 are parallel to the limiting rod 19. Rotate the rotating sleeve 17 to drive the multiple sets of mounting blocks 18 to rotate, thereby pushing the multiple sets of limiting rods 19 to be inserted into the limiting holes 21 to fix the limiting sleeve 16, and complete the fixation of the fixing plate 8. The universal wheel 10 limits the outer wall of the mill cylinder 2.

[0040] When it is necessary to release the limiting position of the mill cylinder 2, the rotating sleeve 17 drives multiple sets of limiting rods 19 to disengage from the limiting hole 21, releasing the fixing of the limiting sleeve 16. Multiple sets of reset springs 25 push the limiting sleeve 16 to release the contact with multiple sets of push blocks 15. Multiple sets of tension springs 26 pull the locking block 13 to disengage from the locking groove 14. At the same time, the locking block 13 pushes the sliding rod 12 and causes the push block 15 to slide along the movable groove 24, releasing the contact with the insertion rod 7. The compression spring 27 resets and pushes the abutment plate 28. The abutment plate 28 abuts against the positioning rod 23 and pushes the insertion rod 7 to disengage from the fixing sleeve 11 and the insertion hole 6, completing the unlocking of the fixing plate 8.
