[0022] Example
[0023] refer to Figure 1 , Figure 2 and Figure 3 as well as Figure 4A multifunctional rotary shaft turning device for a stirred tank in a polydimethylsilane production line is disclosed. This device is mounted on the rotating shaft 1 of the stirred tank and includes a handle 2 and a ratchet head connected to the handle 2. The ratchet head contains a lower half-gear 41 and an upper half-gear 42, with the upper half-gear 42 positioned above the lower half-gear 41. When the upper half-gear 42 and lower half-gear 41 are engaged on the rotating shaft 1, they are fastened together by gear connecting bolts 43. Two opposing limiting rods 51 are connected to the sides of the ratchet head below the lower half-gear 41, respectively. The two limiting rods 51 are connected to the sidewalls of the ratchet head via elastic elements. A reversing paddle 53 is located in the middle of the ratchet head between the two limiting rods 51. When the reversing paddle 53 rotates towards one of the limiting rods 51 and abuts against it, the end of the limiting rod 51 separates from the lower half-gear 41. This structure, with its unidirectional rotation function, avoids reverse rotation of the mixing vessel's rotating shaft 1, reducing the risk of equipment damage and personnel injury due to improper operation and ensuring the safety of the maintenance process.
[0024] The upper gear 42 is threaded with a locking bolt 44. When the upper gear 42 and the lower gear 41 are engaged on the rotating shaft 1 of the mixing vessel, the locking bolt 44 is threaded through the upper gear 42 and tightened on the rotating shaft 1. With this structure, the device adopts a split design, directly installed on the rotating shaft 1 of the mixing vessel. The depth of the locking bolt 44 can be adjusted according to the size of the rotating shaft 1 to accommodate different sizes of rotating shafts, thus having wide applicability.
[0025] The upper gear 42 and the lower gear 41 form a locking hole 6 at their center for engaging the rotating shaft of the mixing vessel. The cross-section of the locking hole 6 is a regular hexagon. This structure divides the gear design into upper and lower parts. The upper gear 42 and the lower gear 41 are fixed on both sides with gear connecting bolts 43, and the rotating shaft 1 of the mixing vessel is fixed in the middle with a locking bolt 44. Since the part being used is a round shaft, if the inner ring of the gear were designed as a circle and fixed only by a single locking bolt 44, it would be difficult to tighten properly. Therefore, designing the cross-section of the locking hole 6 as a hexagon significantly improves its reliability after engagement, thereby limiting axial and radial displacement and ensuring the stability and reliability of the device.
[0026] The ratchet head includes a ratchet seat 31, and a detachably connected ratchet cover 32 is provided above the ratchet seat 31. The ratchet cover 32 is rotatably connected to one end of the ratchet seat 31 via a hinge 7, and the other end of the ratchet cover 32 is detachably connected to the ratchet seat 31 via a locking bolt. This structure facilitates the inspection and replacement of components located inside the ratchet head.
[0027] The reversing lever 53 is rotatably connected to the ratchet seat 31, both limit rods 51 are rotatably connected to the ratchet seat 31, and the handle 2 is fixedly connected to the ratchet seat 31.
[0028] The elastic element is a spring 52. One end of the spring 52 is fastened to the inner wall of the ratchet seat 31, and the other end of the spring 52 is fastened to the outer wall of the limit rod 51. With this structure, the spring 52 provides support and cushioning, ensuring that the gear is always in the correct position and providing a certain amount of buffering force during rotation, making the device operate more smoothly.
[0029] In practical use:
[0030] I. Installation Steps:
[0031] 1. Prepare components: Confirm that all sub-components of the device are complete, including handle 2, ratchet seat 31, ratchet cover 32, lower half gear 41, upper half gear 42, gear connecting bolt 43, locking shaft bolt 44, limit rod 51, spring 52, reversing lever 53, etc. (e.g.) Figure 1 and Figure 2 (As shown); Clean the surface of the rotating shaft 1 of the mixing vessel to ensure it is free of oil or rust.
[0032] 2. Install the upper and lower gear halves: Secure the hexagonal locking holes 6 of the lower gear 41 and upper gear 42 onto the rotating shaft 1 of the mixing vessel, ensuring a tight fit (e.g., ...). Figure 2 (As shown); use gear connecting bolts 43 to fasten the lower half gear 41 and the upper half gear 42 (as shown). Figure 2 (As shown).
[0033] 3. Secure the locking bolt: Screw the locking bolt 44 into the top of the upper half gear 42 until its end presses against the rotating shaft 1 to prevent axial slippage of the entire device (e.g., Figure 2 (As shown).
[0034] 4. Assemble the ratchet head: Connect the ratchet cover 32 to the ratchet seat 31 via the movable hinge 7, and secure the other side with locking bolts, ensuring that the limit rod 5 and spring 52 inside the ratchet head are properly installed (e.g., Figure 1 and Figure 3 (As shown).
[0035] II. Operating Procedures:
[0036] 1. Unidirectional rotation operation:
[0037] Grip handle 2 firmly and apply force in the direction of the target (clockwise or counterclockwise);
[0038] Clockwise rotation: The upper gear 42 and the lower gear 41 drive the rotating shaft 1 of the stirring vessel to rotate synchronously. The limiting rod 51 engages with the lower gear 41 to lock and prevent reverse rotation.
[0039] Counterclockwise rotation: Limit rod 51 disengages, allowing reverse operation (direction needs to be switched via reversing lever 53).
[0040] 2. Switch rotation direction:
[0041] (1) Move the reversing lever 53 to the target limit lever 51;
[0042] (2) When the reversing paddle 53 abuts against the target limiting rod 51, the end of the limiting rod separates from the lower half gear 41 and the lock is released;
[0043] (3) Rotate handle 2 in the opposite direction to complete the direction switching and then reset the reversing paddle 53.
[0044] 3. When disassembling the device, follow these steps:
[0045] (1) Loosen the locking bolt 44;
[0046] (2) Remove the gear connecting bolt 43 to separate the upper gear 42 from the lower gear 41;
[0047] (3) Remove the ratchet head and handle 2.
