Hopper bearing device of road surface paver

Abstract

The invention discloses a hopper bearing device of a road surface paver, belonging to the engineering machinery. The device comprises two sets of symmetrical supporting frames respectively arranged at the lower parts of a left hopper and a right hopper of the paver; each supporting frames comprises a hopper holding plate, a frame bearing plate, a frame fixing plate, a track bearing plate and a track fixing plate; the shape and the size of the hopper holding plate are matched with that of a hopper bottom plate of the paver; when the hopper of the paver is fully unfolded, the hopper bottom plate clings to the hopper holding plate; the frame fixing plate is fixed at the outer side of a frame beam; the upper end of the frame bearing plate is connected with the hopper holding plate while the lower end thereof is overlapped at the upper end of the frame bearing plate; the track fixing plate is fixed at the outer side of a track beam; and the upper end of the track bearing plate is connected with the hopper holding plate while the lower end thereof is fixed at the outer side of the track fixing plate through a bolt. The invention has the positive effects of: decomposing the impact force suffered by the hopper onto the frame so as to ensure that the stress of the hopper is rational and the service life of the hopper is prolonged, and ensuring that the mounting and the dismounting are convenient.

Description

technical field [0001] The invention relates to a construction machine, in particular to a road paver hopper support device. technical background [0002] The pavement paver is the most commonly used road paving machine. The hopper of the paver has two left and right sides, and the hopper is driven to rotate by a hydraulic cylinder. Unloading materials from the dump truck into the hopper will have a very large impact on the hopper, which will easily cause deformation of the hopper, and in severe cases, the hopper will be scrapped. The hopper support method of the existing pavement paver is to install additional rubber pads on the frame beam. When the left and right hoppers were in the maximum open state, the front parts of the left and right hoppers were in contact with the left and right rubber pads. This method has a certain effect, but due to the limited area of ​​the rubber pad and the frame, the force-bearing area of ​​the left and right hoppers and the rubber pad is l...

Problems solved by technology

This method has a certain effect, but due to the limited area of ​​the rubber pad and the frame, the force-bearing area of ​​the left and right hoppers and the rubber pad is limited, thus increasing the area per unit area of ​​the hopper. Bearing pressure, and due to the material factors of the rubber itself and the factors of the paving site environment, the rubber pads are easy to age, resulting in frequent replacement cycles of the rubber pads
