1000 t凹体运梁车液压顶升系统设计

Design of Hydraulic Iacking System for 1000 ton Concave Girder Transport Truck

1000 t运梁车的顶升系统对于预制箱梁从运梁车上起升性能起着至关重要的作用。针对1000 t运梁车的顶升系统,通过详细计算,得出顶升力。考虑1000 t运梁车的额定起升速度,对液压系统进行设计,使其满足最大负载时起升的需要,保证1000 t运梁车在额定负载时以额定速度正常顶升和下降;同时,使得顶升油缸起升下降稳定,不超速,并在实际运用时取得了良好效果。

The jacking system of 1000 t girder carrier plays an important role in lifting performance of prefabricated box girder from girder carrier.Aiming at the jacking system of 1000 t beam truck,the jacking force is obtained through detailed calculation.Considering the rated lifting speed of 1000 t beam truck,the hydraulic system is designed to meet the needs of lifting when the maximum load,so as to ensure the normal lifting and lowering of 1000 t beam truck at the rated speed when the rated load;At the same time,it makes the jacking cylinder rise and fall stably,not overspeed,and has achieved good eff ect in practical application.
