Description

Technical Field

[0001] The utility model relates to a motor platform support frame of a port cantilever conveyor, belonging to the technical field of motor support equipment. Background Art

[0002] Different types of cantilever conveyors are used in the loading operations at ports, and the motor of one type of cantilever conveyor must be fixedly supported by a support platform. The motor support platform currently used is a single support rod structure, and the upper end of the support rod is fixedly connected by a pin shaft, which has poor stability, causing the motor to swing left and right with a large amplitude. In addition, the output torque of the motor is large, which makes the pin shaft at the upper end of the support rod subject to a large torsional force. The pin shaft is very likely to be twisted, deformed and broken under the action of the torsional force and the deadweight of the motor. Since the support rod is only connected by a pin shaft, it is easy to cause the motor to vibrate, reducing safety. Therefore, it is very necessary to improve the existing motor support platform.
