Problems solved by technology

[0004] If a pure motor is used to drive a long-distance belt conveyor, in order to meet its high power demand, the volume of the motor needs to be large, which makes the reasonable arrangement of the motor on the belt conveyor extremely inconvenient, and a reducer must be added to realize the motor. Low-speed and high-torque conditions, which further increase the volume of the motor drive system

Abstract

The invention discloses a hybrid-driven long-distance belt conveyor. The hybrid-driven long-distance belt conveyor comprises speed reducers, gate control systems, driving rollers and a conveying belt. The hybrid-driven long-distance belt conveyor further comprises kinetic potential storage and transportation circuit and motor combination drive systems, supercapacitor sets and controllers. By recycling kinetic energy of the belt conveyor in the braking process, electro-hydraulic hybrid drive of the long-distance belt conveyor is achieved. According to the hybrid-driven long-distance belt conveyor disclosed by the invention is high in energy utilization rate, impact and vibration of an operating mechanism are eliminated, dynamic stresses of the operating mechanism are reduced, the degree of fatigue is lowered and the service life of main drive motors and the operating mechanism is prolonged.

Description

technical field [0001] The invention belongs to the field of belt conveying mechanical equipment, and in particular relates to a long-distance belt conveyer with hybrid drive. Background technique [0002] Long-distance belt conveyors are widely used in the production process of modern industrial enterprises. They are an indispensable part of the production process of modern industrial enterprises. They are basic equipment in material handling and production mechanization systems. Their performance determines the transportation mechanization and production. Efficiency and level of mechanization. How to correctly select a reliable and controllable drive device, control the start-up process to avoid excessive stress and oscillation, and improve the overall economy of the equipment has become a key issue in the design. [0003] At present, the commonly used drive devices include AC frequency conversion speed regulation drive system, liquid viscous friction soft start system, h...
