Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
As shown in fig. 1 and 2, the embodiment provides a fully-closed top-open type hydraulic opening and closing device, which comprises a rear cover plate 3 fixedly arranged above an enclosure 11, a top cover plate 2 connected with one side of the rear cover plate 3 through a hinge 5, and a front cover plate 1 connected with the other side of the top cover plate 2 through a hinge 4, wherein the enclosure 11, the rear cover plate 3, the top cover plate 2 and the front cover plate 1 are enclosed together for closing a silo opening, each cover plate adopts a square tube of 50 × 50 × 3 as a frame, a square tube of 30 × 30 × 3 as reinforcement, a steel plate with the thickness of 0.3 mm-1 mm is laid on the surface according to strength requirements, two hydraulic cylinders 6 are arranged in the silo, the hydraulic cylinders 6 are symmetrically arranged at two sides of the top cover plate 2, the lower ends of the hydraulic cylinders 6 are arranged on a base, the upper ends of the hydraulic cylinders are hinged with the top cover plate 2 through an upper hinge base 7, the hydraulic cylinders 6 are controlled by a hydraulic device 8, the front cover plate 1 and the top cover plate 2 are rotated upwards through the force of the hydraulic cylinder 6 to be opened, the front cover plate 1 and the dump truck is always kept perpendicular to the ground through the hinge 4 in the design, the optimized structure, and the.
In this embodiment, a stopper 10 is further provided, and the stopper 10 is used for limiting the rotation angle of the top cover plate 2. The stopper 10 is arranged at the rear cover plate 3 and is positioned at the position where the top cover plate 2 is hinged with the rear cover plate 3, so that the safety protection effect is achieved, and the installation position of the stopper 10 is adjusted to enable the angle B when the top cover plate 2 is opened and the opening distance A of the front side cover plate 1 to meet the use requirements.
In this embodiment, the hydraulic device 8 is installed on the rear cover plate, thereby saving installation space.
In this embodiment, a reinforcing rib 9 is provided at the lower end of the top cover plate, and the upper cylinder base 7 is connected to the reinforcing rib 9. Utilize strengthening rib 9 and upper cylinder seat 7 to do the fastness to top apron 2 and strengthen, guarantee that top apron 2 can not warp at the in-process of opening.
