Design and Optimization of the Bridge Expansion Joints Cleaning Machine

摘要

Bridges are hinges of city road and railway, which play an important function in national economy. The changes of temperature affect the length of the highway bridge beams, so the bridge should be equipped with the expansion joint device. When vehicles pass the bridge, dust flies up and clogs the gap of the bridges. The bridge expansion joints should be cleaned in time. The main task of this project is to study a kind of device used to clean the bridge expansion joints, which including two parts: the cleaning system and vacuum dust removal system. First, we use the sweeping wheels to loose dust, then the air-blower to blow away the dust. The optimization of vacuum dust removal system was discussed in this paper. Especially, the Cyclone dust removal device works well. The machine is of higher productivity, wide application, low energy consumption, simple structure compared with similar equipments.
