The invention discloses a conveying
system and method capable of adjusting the blanking speed at a
constant speed for steel shell concrete. The
system comprises a pouring trolley frame, a hopper and aconstant-speed blanking
system, the hopper is fixed on the pouring trolley frame, and the constant-speed blanking system is connected with a hopper
discharge port. The constant-speed blanking systemis composed of a blanking valve, a gear blanking device, a
speed reduction frequency converter, a lead screw lifter and two motors, the inner structure of the blanking valve comprises a blanking baffle and a driving shaft, one motor is arranged at the top end of the lead screw lifter, the lead screw lifter is hinged to a driving shaft, and the driving shaft is connected with the blanking baffle. By means of the system and method, the defects that a concrete
surface layer is uneven and air is difficult to remove in a later period of pouring are overcome. And the working efficiency and the capacity are improved, the production cost is reduced, the construction qualification rate is improved, local cavities, large-area air holes and
honeycomb pitted surfaces of a steel shell and the concretesurface layer are prevented from being generated during pouring, and the
engineering quality is effectively guaranteed.
