Embodiment Construction

[0017] exist figure 1 Among them, a cylindrical transport box door opening and closing device includes a cylindrical box body 1 and two arc-shaped box doors 2 . Wherein, the top of the box body 1 has an open box mouth; two ends of the box door 2 are respectively provided with a connecting plate 3 .

[0018] Connecting plate 3 can adopt an integral connecting plate, and this connecting plate is an arc-shaped triangular connecting plate matching with the arc shape of the box door, and can also adopt the connecting plate that the arc-shaped plate and the triangular frame combine. Such as figure 1 As shown, what is preferred in this embodiment is the connecting plate combined with the arc-shaped plate and the triangular frame.

[0019] exist figure 1 Among them, the box door 2 is coaxially hinged at both ends of the box body 1 through the corresponding connecting plate 3 and hinge shaft 11 respectively, and the box door 2 rotates around the hinge shaft 11 to leave or close the ...

Abstract

The invention discloses a cylindrical conveying box door opening and closing device. The problem that an existing box door opening and closing device is high in manufacturing cost, poor in action synchronism and not tight in closing of a box door. The cylindrical conveying box door opening and closing device comprises a cylindrical box body and two arc-shaped box doors, wherein connecting plates are respectively arranged at two ends of the box doors; and the box doors are respectively hinged to two ends of the box body coaxially via the connecting plates and articulated shafts. The cylindrical conveying box door opening and closing device is characterized in that two oil cylinders are vertically fixed on end surfaces of two ends of the box body respectively via fixing pieces, a push-and-pull arm is transversely arranged at an end of a piston rod of each oil cylinder, and two chutes are symmetrically formed in each push-and-pull arm; a hinge pin is correspondingly arranged on each connecting plate, and the hinge pins positioned at the same end of the box body are respectively matched with the insides of the chutes correspondingly; and the oil cylinders communicate with a hydraulic station via hydraulic tubes respectively, and the working state of the hydraulic station is controlled via a control device. The using frequency of the oil cylinders is low, and the manufacturing cost is low; the oil cylinders drive the box doors to open and close, the action synchronism is good, a driving force is sufficiently, and the box doors are closed tightly.

Description

technical field [0001] The invention relates to a rigid large container specially suitable for transportation, in particular to a cylinder type transportation box door opening and closing device. Background technique [0002] At present, most materials are transported by conventional hopper trailers. During the transportation process, open hoppers are easy to leak materials and cause harm to the environment. In order to facilitate transportation and loading and unloading, the CN106241083A Chinese invention patent applied by the applicant and published on December 21, 2016 discloses "a cylindrical transport box", which includes a cylindrical box body, hinged on the box body The two ends of the box door rotate around the box axis. The two ends of the box are respectively equipped with cylinders corresponding to the box doors. The supports of the cylinders are respectively hinged on the box frame, and the piston rods are hinged on the corresponding box doors superior. The abo...
