Abstract

The invention discloses a storage functional unloader in the unloading equipment domain, which comprises the following parts: lift system, spiral bulk and piston connection rod of hydraulic cylinder on the trolley operating system, wherein the lift system elevates the spiral bulk at the power-off time; the gear pump, two-step two-way hand change-over valve, one-way valve, three-step four-way hand change-over valve, speed-regulating valve, balanced valve and pilot-controlled one-way valve are set on the oil way between lower cavity of hydraulic cylinder and oil tank sequently; the flow-collecting shunt valve is set on the oil way between upper cavity of hydraulic cylinder and three-step four-way hand change-over valve; the one-way valve is fixed on the oil way between gear pump and accumulator; the hand change-over valve is set on the oil way between accumulator and three-step four-way hand change-over valve. The invention can be used in the steam-electric power plant and discharging operation.

Description

Technical field: [0001] The invention relates to a car unloading machine, in particular to a car unloading machine with energy storage function. Background technique: [0002] In thermal power, building materials, grain, chemical and other granular or powdery material enterprises, due to the large amount of transported materials, unloaders are generally used for mechanized unloading. The longitudinal and lateral shifts are completed by the cart running mechanism and the trolley running mechanism. The lifting mechanism adopts a chain drive system, and its disadvantage is that the lifting movement is not stable, especially when there is a power failure during the unloading process, the screw body cannot be lifted, and the vehicle cannot leave the site, which affects the transportation operation. Invention content: [0003] The technical problem to be solved in the present invention is to design a car unloader whose lifting mechanism has a stable lifting mechanism and the sc...
