Working method of the present utility model is: strong planet tapper structural concrete vibrating head drives tapper rotation in the barred body by flexible axle, make the conical section of tapper become line to contact and roll along raceway with raceway, the tapper of eccentric rotation produces centrifugal force, and make the vibrating head barred body produce dither according to the speedup principle of planetary motion, cone is when dynamic, middle short cone is line with raceway and contacts, and the bus of other cone is parallel with the bus of barred body cylindrical shroud tube inner chamber and maintain the gap.
Strong planet tapper structural concrete vibrating head, can be according to the needs of operating mode, determined barred body external diameter and plane, vibrating head tip top to the bearing centre of gyration apart from length after, the size of determining other major part in the barred body is one group of nondimensional modulus, the housing internal diameter optimum value of short sleeve is 0.78～0.83 times of barred body external diameter in the cylindrical sleeve, length is plane, vibrating head tip top 0.22～0.24 times to bearing centre of gyration distance, the housing internal diameter optimum value of long sleeve is 0.66～0.71 times of barred body external diameter, and length is plane, vibrating head tip top 0.495～0.506 times to bearing centre of gyration distance; Tapper in the sleeve is of a size of, the tapper cone top diameter in raceway left side is 0.54～0.59 times of barred body external diameter, length is plane, vibrating head tip top 0.20～0.22 times to bearing centre of gyration distance, the tapper cone diameter at butt end on raceway right side is 0.58～0.63 times of barred body external diameter, and length is plane, vibrating head tip top 0.48～0.51 times to bearing centre of gyration distance; Under the duty angle of tapper center and sleeve centerline be (0.10～0.3) doubly the vibrating head external diameter and plane, vibrating head tip top to the merchant of bearing centre of gyration distance; The tapering of the short cone of raceway tapering and tapper can be tried to achieve with conventional design formulas according to the angle of tapper center and sleeve centerline under the duty.
Limit excellent shell systems and the distribution of tapper mass of system by above-mentioned modulus, can optimize the structure design of vibrating head, increased the pivot angle under the tapper duty--be the angle of tapper center and sleeve centerline under the duty, can make this angle increase 5%～12%; The major part of tapper is three sections cones, in working order down, middle short cone becomes line to contact with raceway, the bus of its both sides cone is parallel with barred body barrel bore bus and maintain the gap, this has just made full use of the sleeve system inner chamber, increased the quality of tapper, thereby made vibrating head not improve rational vibration parameters of maintenance and the bigger exciting force of generation under the condition frequently of shaking; The length of the most advanced and sophisticated solid section of strong planet tapper structural concrete vibrating head of the present utility model can reach plane, vibrating head tip top 0.13～0.14 times to bearing centre of gyration distance, thereby can be designed to threaded solid tip to tip, so both be convenient to processing, crack when having avoided heat treatment again, improved the reliability of vibrating head, tip wearing and tearing back maintenance is also more convenient.
The utility model is applicable to vibrated concrete in the concrete constructions such as building, harbour, bridge, water conservancy project.
