Description

TECHNICAL FIELD

[0001] The application relates to the technical field of encoder support, in particular to a flexible encoder mounting support for a port. BACKGROUND

[0002] A cantilever telescopic mechanism of a port loading machine is a key component for ensuring accurate loading of bulk cargo, which moves along a portal through a belt conveyor to realize operation coverage of different tracks of trains. The driving of the mechanism depends on a three-in-one speed reducer controlled by a frequency converter, an open gear at the output end of the speed reducer is engaged with a rack to convert power into moving energy of the belt conveyor. In order to control the telescopic stroke in real time, a driven gear needs to be arranged beside the open gear of the three-in-one speed reducer, and an encoder body is fixed to the associated structure of the driven gear through a special support, stroke data is converted by using the encoder to collect gear rotation signals, and the loading position is ensured to be accurate.

[0003] However, when the open gear drives the belt conveyor to move, the belt conveyor is affected by load fluctuation (such as material flow change), and continuously exerts a radial extrusion force on the driven gear. The extrusion force is directly transmitted to the encoder support through the driven shaft, and the existing support is mostly a rigid fixed structure, which is easy to cause deformation of the support base and fatigue cracking of the welding part between the connecting plate and the side swing frame under long-term unidirectional load, thereby forming irreversible mechanical damage. The deformation of the support further causes the position of the encoder to deviate, resulting in inaccurate collection of stroke signals and affecting the loading accuracy.
