Abstract
The utility model discloses a steel pipe arch rib pushing movement roller box. The movement roller box comprises four roller box rollers, rotating shafts, connection capstan stands and connection section steel. The roller box rollers and the connection capstan stands are fixedly connected through the rotating shafts. The connection section steel is welded above the connection capstan stands to enable the four roller box rollers to be connected as a whole. Each roller is a steel roller that is [Phi] 50cm in diameter. Each rotating shaft is a steel pin which is [Phi] 10cm in diameter. Each connection capstan stand is formed by two 100cm*50cm*4cm steel plates on the top surface and 2.4cm-thick steel plates at two sides. The connection section steel is I28a I-steel. The steel pipe arch rib pushing movement roller box is reasonable in structural design. The construction time is greatly shortened, the work efficiency is improved, influence upon traffic on highways is minimized during construction of a steel pipe arc rib, and safety coefficients are increased.
Description
Technical field
The utility model relates to a kind of roller box, more specifically says a kind of steel tube arch rib pushing tow walking roller box.
