Rollerless folding cover plate

Abstract

This utility model relates to a rollerless folding cover plate, belonging to the technical field of asphalt insulation box cover plates. It includes an asphalt insulation box, a front cover plate, and a rear cover plate. The top of the asphalt insulation box is fixedly connected to a first hinge, a second hinge, an earring, and a fixed support. A hydraulic cylinder is hinged to the outer surface of the fixed support. The top of the rear cover plate is fixedly connected to an upper seat. A lever is fixedly connected to the rear end of the front cover plate. A steel wire rope is arranged between the earring and the lever. A steel wire rope roller is fixedly connected to the front end of the rear cover plate. The front end of the steel wire rope roller has a smooth surface. The rear cover plate is hinged to the asphalt insulation box via a second hinge. This rollerless folding cover plate uses a hydraulic cylinder to control the swing of the rear cover plate and utilizes a steel wire rope, lever, and steel wire rope roller to control the flipping angle of the front cover plate, achieving folding of the front and rear cover plates. This results in better applicability, a more reasonable design, and a wider range of applications.
