TLDR
In this article, a double-screw synchronous lifting mechanism is described, which consists of a base, a top plate, a first screw rod, a second screw rod and a lifting platform, a rotary drive assembly, a driving synchronous pulley and a synchronous belt.Abstract:
The invention discloses a double-screw synchronous lifting mechanism which comprises a base, a top plate, a first screw rod, a second screw rod, a lifting platform assembly, a rotary drive assembly, a first driven synchronous pulley, a second driven synchronous pulley and a synchronous belt. The top plate is arranged above the base. One end of the first screw rod and one end of the second screw rod are arranged on the base in a rotatable mode, the other end of the first screw rod and the other end of the second screw rod are arranged on the top plate in a rotatable mode, and the first screw rod and the second screw rod are parallel. The lifting platform assembly is matched with the first screw rod and the second screw rod in a threaded mode and located between the base and the top plate. The rotary drive assembly is arranged on the base or the top plate. A driving synchronous pulley is arranged on an output shaft of the rotary drive assembly. The first driven synchronous pulley is arranged on the first screw rod and identical with the driving synchronous pulley. The second driven synchronous pulley is arranged on the second screw rod and identical with the driving synchronous pulley. The synchronous belt enables the driving synchronous pulley to be connected with the first driven synchronous pulley and the second driven synchronous pulley. The double-screw synchronous lifting mechanism can effectively lower the stress of each screw rod, and the ascending and descending process of the lifting platform can be more stable.read more
