Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1 In the embodiment of the utility model, a lifting reducer for a spinning machine includes a reducer case 1 and an upper cover plate 3 is arranged on the upper end of the reducer case 1, a lifting ring 2 is fixedly installed on the upper end of the upper cover plate 3, the upper cover plate 3 is connected to the reducer case 1 by bolts, and the upper cover plate 3 is connected to the lifting ring 2 by threads, which is convenient for the staff to carry, and the lifting ring 2 can also be unscrewed, and lubricating oil can be poured onto the gear inside the reducer through the mounting hole, which is convenient to use. A mounting plate 6 is arranged at the lower end of the reducer case 1, which can fix the reducer case 1, and a protective plate 4 is arranged on one side of the reducer case 1; the protective plate 4 is composed of three side baffles, and the three side baffles are respectively located at the front, one side and bottom of the reducer case 1, and the three side baffles are arranged at right angles to each other, which can protect the reducer case 1 from multiple sides and avoid some safety problems.

[0021] like Figure 2 As shown: a primary transmission shaft 7, a secondary transmission shaft 8 and a tertiary transmission shaft 9 are arranged in parallel inside the reduction gear box 1, and the primary transmission shaft 7, the secondary transmission shaft 8 and the tertiary transmission shaft 9 are connected through a gear set 11. A motor drive hole 12 is arranged at one end of the reduction gear box 1, and an auxiliary drive hole 13 is arranged at the lower end of the motor drive hole 12. A speed measuring piece 16 is fixedly installed at one end of the tertiary transmission shaft 9, and a speed sensor 10 is arranged on one side of the tertiary transmission shaft 9 on the reduction gear box 1. The speed measuring piece 16 is driven to rotate by the rotation of the tertiary transmission shaft 9. When the speed measuring piece 16 passes through the speed measuring sensor 10, the rotation speed of the speed measuring piece 16 can be detected.

[0022] like Figure 3 As shown: a transmission ring 5 is installed at the other end of the three-stage transmission shaft 9, and the transmission ring 5 is fixedly connected to the three-stage transmission shaft 9 through a fixing bolt 18, and a transmission chain 19 is arranged on one side of the transmission ring 5, and the transmission chain 19 is fixedly connected to the transmission ring 5 through a chain fixing hole 17. The transmission ring 5 is driven to rotate by the three-stage transmission shaft 9, and the rotation of the transmission ring 5 can pull the transmission chain 19 downward or move upward. The transmission chain 19 can be driven to do reciprocating motion by electric forward rotation or flipping.

[0025] The working principle of the utility model is: after the equipment is fixed, the output shaft of the motor is sleeved with a gear, and the gear is meshed and connected with the driving gear 20, and the driving gear 20 drives the gear set to rotate. Since there are three transmission shafts running through the middle of the gear set, the rotation of the gear set can drive the three-stage transmission shaft 9 to rotate. One end of the three-stage transmission shaft 9 is connected with a transmission ring 5, so the three-stage transmission shaft 9 drives the transmission ring 5 to rotate. The rotation of the transmission ring 5 can pull the transmission chain 19 downward or move upward. Through electric forward rotation or reversal, the transmission chain 19 can be driven to do reciprocating motion. The reciprocating motion of the transmission chain 19 can drive the main shaft of the spinning frame to do reciprocating motion. If the line is powered off or the equipment is debugged or maintained, the motor will not start. The same effect can be achieved by manually rotating the auxiliary drive shaft 14, which is convenient to use.
