Embodiment Construction
[0024] Dynamic compaction, including a support frame 2 with a roller 1, a rotating shaft 3 is supported on the supporting frame 2, and a driven wheel 4 driven by a driving mechanism is fixed on the rotating shaft 3; Wheel 5, any eccentric wheel on the left side of the center line of the rotating shaft 3 is a group with any eccentric wheel on the right side of the center line of the rotating shaft. The eccentric shaft hole of the wheel is directly above the center of the eccentric wheel (at this time, its phase can be considered as zero), and the eccentric shaft hole of the other eccentric wheel should be directly below the center of the eccentric wheel (at this time, its phase is 180 degrees), By analogy, the inertia wheels 6 are fixed on both sides of the rotating shaft 3, and the outer edge of each eccentric wheel 5 is covered with an inherent bearing 7, and the bearing 7 is covered with a rammer assembly, which includes a rammer 8, one end and a tamper The rammer rod 9 conn...

The invention relates to tamping equipment for building foundations, roadways and the like, in particular to a power dynamic compaction tool which solves the problems that a gravity dynamic compaction tool has low working efficiency, high energy consumption and unsafely in usage. The power dynamic compaction tool comprises a support frame with rollers, wherein a rotating shaft is supported on the support frame, and a driven wheel driven by a driving mechanism is fixed on the rotating shaft; eccentric wheels are fixed at one of two sides of a center line of the rotating shaft, and the quantities of the eccentric wheels at two sides are the same, any one eccentric wheel at the left side of the center line of the rotating shaft and any one eccentric wheel at the right side of the center line of the rotating shaft are in one group, when installation is performed, the two eccentric wheels in each group, relative to the position of the rotating shaft, have 180-degree phase difference, an inertia wheel is fixed at one of two sides of the rotating shaft, a bearing is sheathed and fixed at the outer edge of each eccentric wheel, a rammer assembly is sheathed on the bearing, and comprises a rammer, a rammer rod of which one end is connected with the rammer and a bearing bush connected with the other end of the rammer rod, and the rammer assembly is sheathed on the bearing at the outer edge of the eccentric wheel through the bearing bush. The power dynamic compaction tool can be used for the application fields such as road pavement, treatment of building foundations, foundation reinforcement and the like.
Description
technical field [0001] The invention relates to compacting equipment for building foundations, foundations, road surfaces, etc., in particular to a dynamic dynamic compaction. Background technique [0002] The main large-scale equipment currently used for compaction is gravity compaction. Gravity compaction is powered to lift the rammer to a high place, and then falls freely, and the rammer relies on the strong gravitational potential energy to realize the compaction function. Gravity compaction has the disadvantages of low work efficiency, high energy consumption, and high safety risks. Contents of the invention [0003] In order to solve the problems of low working efficiency, high energy consumption and high safety risk of gravity dynamic compaction, the present invention provides a dynamic compaction method. The rammer of the power dynamic ram is tamped under the continuous drive of power. [0004] The present invention is realized by adopting the following technica...
