Embodiment Construction

[0032] The specific implementation manner of the present invention will be described in further detail below by describing the best embodiment with reference to the accompanying drawings.

[0033] A driving system for a door machine turning mechanism, including a motor 3; the motor 3 is connected to a speed reducer 4 through a torque-limiting permanent magnet coupling 1-2; the invention discloses a driving system for a door machine turning mechanism. The invention uses a torque-limiting permanent magnet coupling to replace the limit torque limiter, which makes the protection action of the entire drive system more sensitive, and can automatically recover at the same time, reducing or avoiding damage to parts.

[0034] As a preference, the torque-limiting permanent magnet coupling 1-2 in the present invention is connected to the motor shaft through a connecting piece; the above-mentioned connecting piece can also be a bushing structure, which can be called the first bushing 101; ...

Abstract

The invention relates to the field of portal crane swing equipment, in particular to a portal crane swing mechanism driving system which comprises a motor. And the motor is connected with the speed reducer through a torque-limiting permanent magnet coupling. According to the invention, a limit torque limiter is replaced by the torque-limiting permanent magnet coupling; the whole driving system ismore sensitive in protection action, meanwhile, automatic recovery can be achieved, damage to parts is reduced or avoided, meanwhile, a novel torque limiting type permanent magnet coupler is adopted,the driving system can have the soft start function, and the stability of the whole system is better guaranteed.

Description

technical field [0001] The invention relates to the field of door machine turning equipment, in particular to a door machine turning mechanism drive system. Background technique [0002] Portal cranes, commonly known as "gantry cranes", refer to cranes traditionally used at the front of port terminals. On the gate-shaped base running along the ground track, a rotatable lifting arm frame is set, which has four cooperative mechanisms of lifting, turning, luffing, and running. Railway trains or other vehicles can pass under the gate seat. Carry out vehicle and ship loading and unloading and transfer and direct fetching operations. The slewing mechanism is a mechanism that makes the slewing part of the crane rotate around the slewing centerline in the horizontal plane. The slewing mechanism is usually composed of a slewing support device and a slewing drive device. The slewing drive device is used to drive the slewing part to achieve slewing motion relative to the non-swivel pa...
