[0030] like Figures 1-4 As shown, this utility model provides a synchronous lifting mechanism for installation within a curing line 1 to lift and lower workpieces on the curing line 1. The synchronous lifting mechanism comprises:

[0031] At least two bases 2 are arranged at intervals;

[0032] At least four rotating lifting devices 3, with at least two rotating lifting devices 3 distributed on each base 2;

[0035] At least two platforms 5, and the lifting parts of at least two rotating lifting devices 3 on each base 2 are simultaneously connected to one platform 5.

[0036] Specifically, to address the problem that current segmented lifting mechanisms, where each platform determines its lifting position via sensors, often suffer from height discrepancies due to limitations in signal transmission time and sensor sensitivity, leading to workpiece deviations, this invention provides a synchronous lifting mechanism. The synchronous lifting mechanism uses a screw jack as its rotary lifting device. The input of each rotary lifting device 3 on the same base 2 is connected to a reversing output of a reversing device 4, and the output of the rotary drive is connected to the input of each reversing device 4. When lifting a workpiece via at least two platforms 5, the rotary drive is controlled... When the drive device is working, the rotary drive device can drive the input part of each reversing device 4 to rotate, and then drive the input parts of at least two rotary lifting devices 3 distributed on each base 2 to rotate through the transmission reversing of each reversing device 4. At this time, at least two platforms 5 can be lifted and lowered simultaneously to lift and lower the workpiece. During the lifting process, the synchronous lifting mechanism can achieve the lifting and lowering of at least two platforms 5 through a set of mechanical power systems. Compared with the control of traditional sensors, it ensures that the lifting height of at least two platforms 5 is consistent, avoids deviation of the workpiece during lifting and lowering, and saves the production cost of the synchronous lifting mechanism through a set of mechanical power systems.

[0047] Specifically, the first drive shaft 7 is used to connect the two commutators. The universal coupling can avoid the problem of a small height difference between the two commutators and avoid generating internal stress on the first drive shaft 7.

[0048] Preferably, the commutation output of the commutator is connected to the input of the rotary lifting device via a universal coupling or via a second transmission component.

The drive motor 6 can drive the input part of each commutator to rotate. Through the transmission of one commutator, two rotary lifting devices 3 can be driven to work at the same time. At this time, at least two platforms 5 can be lifted and lowered at the same time to drive the workpiece to lift and lower. During the lifting process, the synchronous lifting mechanism can realize the lifting and lowering of at least two platforms 5 through a set of mechanical power system. Compared with the control of traditional sensors, it ensures that the lifting height of at least two platforms 5 is consistent and avoids deviation of the workpiece during lifting and lowering.
