Sliding intermediate supporting system for forced-cooling sliding column of spiral ship unloader

Abstract

The invention discloses a sliding intermediate supporting system for a forced-cooling sliding column of a spiral ship unloader. The sliding intermediate supporting system comprises a connecting shaft, a supporting outer tube, open-web sliding columns, a double-ended spiral blade, spring mandrels and disc springs, wherein the two ends of the connecting shaft are equipped with flanges; the double-ended spiral blade is packaged on the shaft neck of the connecting shaft in a Huff-shaped mode; the periphery of the double-ended spiral blade is connected with two thin-wall semi-cylindrical tubes; the inner periphery of the double-ended spiral blade is connected with two thick-wall semi-cylindrical tubes; the double-ended spiral blade is fastened onto the shaft neck of the connecting shaft through the two thick-wall semi-cylindrical tubes; the two ends of the supporting outer tube are equipped with flanges; a plurality of bosses are arranged on the tube wall of the supporting outer tube; a centering hole is bored in each boss; the open-web sliding columns are arranged in the holes; disc spring groups are mounted in the open-web sliding columns; the disc spring groups comprise the spring mandrels and a plurality of disc springs which are mounted in a superposed mode; the spring mandrels are arranged in a step mode, and are fixedly arranged in end openings of the bosses on the supporting outer tube; and one end of each open-web sliding column is equipped with an arc-shaped curved surface which fits to the surface of each thin-wall semi-cylindrical tube, and has the same curvature with the corresponding thin-wall semi-cylindrical tube.

Description

technical field [0001] The invention relates to the field of screw ship unloaders, in particular to a sliding intermediate support system for forced cooling sliding columns of the screw ship unloader. Background technique [0002] At present, the equipment used to unload granular and small block materials in ports and wharves is mainly grab ship unloader, which is characterized by interval work. A working cycle includes grabbing, lifting, turning, lowering, discharging and return. Its lifting, The main disadvantage is that the turning and discharging links will cause serious dust pollution to the surrounding environment. Spiral ship unloaders are used abroad to unload granules and small block materials, which are characterized by continuous operation. Compared with grab ship unloaders, the dust pollution to the environment during the working process is greatly reduced, and the productivity is also high, which can meet the requirements of wharf operations. However, its suppor...

Problems solved by technology

[0004] In order to solve the deficiencies in the prior art, the purpose of the present invention is to provide a sliding intermediate support system for the strong cooling sliding column of the screw ship unloader, which aims to solve the lack of spiral blades at the connecting shaft of the existing screw ship unloader, which is not suitable for coal unloading Small lump materials and the screw blades at the connecting shaft are continuous without missing, but the vibration and noise are relatively large during operation, which is not suitable for empty operation.
