APPARATUS FOR WING DOOR TYPE CONTAINER

摘要

The present invention provides a wing door type container apparatus, in order to improve productivity through a simplified structure as forming usage convenience by easy open/close switching of a wing door. The wing door type container apparatus of the present invention includes: a container case frame having a space to accommodate cargo in the inside; a wing door which is opened and closed by being connected to an upper part of the container case frame through a hinge axis; a hydraulic cylinder which has one end part hinged to the wing door and another end part hinged to the upper part of the container case frame, and is stretched selectively according to oil pressure in order to open and close the wing door; and an oil pressure control unit for controlling the oil pressure to open and close the wing door by including an oil pressure supply device connected to the hydraulic cylinder through a main passage, and a recovery passage comprising a blocking valve opened and closed selectively as being connected to a pressure-oil tank by being branched from the main passage. The oil pressure supply device includes an automatic oil pressure pump and a manual oil pressure pump connected to the main oil passage by being arranged in parallel with each other. The automatic oil pressure pump supplies a working fluid of the pressure-oil tank to the main passage via a first check valve by amplifying and converting torque of an external rotary force delivered to a first input axis. The manual oil pressure pump supplies the working fluid of the pressure-oil tank to the main passage via a second check valve by converting a discontinuous rotary force along one direction delivered to a second input axis.
