The principle and effect of this basic scheme lie in:

1. compared with the prior art, this device simple structure, the design is ingenious, though also utilized the ground tamping method of traditional ram, this device is different with traditional heavy hammer ground tamping method that this device realizes through bottom plate and first fixed pulley and second fixed pulley that whole heavy hammer ground rammer is portable, has increased the scope of use to the flexibility becomes strong.

2. Compared with the prior art, this device utilizes the limiting plate adjustment ram whereabouts height to the striking speed of adjustment ram, and the characteristic of utilizing the spring beam compression, increase the whereabouts speed of ram, thereby increased the tamping energy of ram whereabouts.

Further, the number of the universal wheels is at least four. The four universal wheels can stably support the whole device to move.

Further, the diameter of the rammer is smaller than or equal to the diameter of the first through hole. The rammer can impact the ground conveniently to generate ramming energy.

Further, the ram is cylindrical. The cylindrical shape can ensure that the tamping can be uniformly distributed, so that the tamping ground is uniformly stressed.

Detailed Description

The following is further detailed by the specific embodiments:

reference numerals in the drawings of the specification include: the device comprises a bottom plate 1, universal wheels 2, a machine base 4, a supporting block 5, a first fixed pulley 6, a second fixed pulley 7, a supporting rod 8, a motor 10, a sliding groove 12, a rammer 14, a spring rod 15 and a limiting plate 16.

Examples are shown in fig. 1 and 2:

a foundation tamping device for civil engineering comprises a bottom plate 1, a base 4, a support rod 8 and a motor 10 base are fixedly connected on the bottom plate 1 from left to right in sequence, the base 4 is U-shaped, a rotatable second fixed pulley 7 is fixedly connected at the upper end of the support rod 8, a plurality of universal wheels 2 are fixedly connected below the bottom plate 1, the number of the universal wheels 2 is at least four, the four universal wheels 2 can stably support the whole device to move, a first through hole is formed in the center of the bottom plate 1, a support block 5 is fixedly connected at the right end, far away from the bottom plate 1, of the base 4, a rotatable first fixed pulley 6 is connected on the support block 5 in a threaded mode, a motor 10 is arranged on the motor 10 base, a winding wire is wound and connected at the output end of the motor 10, the free end of the winding wire penetrates through the second fixed pulley 7, the first fixed pulley 6 and the top end of the base 4 and is fixedly connected with, the diameter of first hammer is less than the diameter of second hammer, and the diameter less than or equal to the diameter of first through-hole of rammer 14 makes things convenient for rammer 14 can strike ground, produces the ramming ability, and rammer 14 is cylindrical, and cylindrical can make ramming ability evenly distributed for the ramming ground atress is even.
