TECHNICAL FIELD

[0001] The present application relates to the field of port freight, in particular to a wear-resistant chute guide rail structure. BACKGROUND

[0002] The telescopic chute is a device commonly used for conveying goods at the port. After the cargo ship arrives at the port, the ship unloader takes out the goods in the ship's hold, and then the telescopic chute is extended into the transfer vehicle to guide the goods into the transfer vehicle.

[0003] When transporting some powdery or small-volume goods such as iron ore powder, coal powder, etc., a soft chute can be used to vertically send the goods down. For some larger objects such as sand or ore, a telescopic chute made of metal can be used to reduce the impact by extending the chute into the transfer vehicle at an angle.

[0004] However, when the telescopic chute is lowered, each section of the chute is prone to continuous rotation, which can cause the hydraulic cylinder controlling the extension and retraction of the chute to be subjected to a large pressure, thereby causing damage. CONTENT OF THE INVENTION
