The utility model provides a pair of foundation stabilization rammer, beneficial effect lies in:

1. before tamping, the pull rope is tightened through the winch, so that the counterweight column acts on the return spring, the return spring accumulates larger elastic potential energy, then the pull rope is released, and at the moment, under the action of the elastic force of the return spring and the gravity of the counterweight column, the tamping plate can generate larger impact force on the foundation, so that the tamping effect is achieved;

2. the design of strengthening mechanism, the effect lies in, after ramming plate effect and solid piece, the reinforcement cover can guarantee that solid piece is vertical effect and ground all the time, and the area of contact of backup pad and ground is big, can disperse the impact force like this, guarantees that the ground atress is even can not cause local settlement.

fig. 3 is a schematic structural diagram of a reinforcing mechanism of a foundation reinforcing and tamping device according to the present invention.

In the figure: the device comprises a base 1, a frame body 2, a fixed seat 3, a fixed pulley 4, a pull rope 5, a limiting plate 6, a sleeve 7, a return spring 8, a counterweight column 9, a tamping plate 10, a solid block 11, a reinforcing mechanism 12, a reinforcing sleeve 121, a supporting plate 122 and an inclined support rod 123.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Example 1:

referring to fig. 1-2, a foundation reinforcement tamping device comprises a frame body 2, wherein a base 1 is fixedly installed at the bottom of the frame body 2, a fixed seat 3 is fixedly installed at the top of the frame body 2, a fixed pulley 4 is rotatably installed on one side of the fixed seat 3 through a pin shaft, a pull rope 5 is installed on the fixed pulley 4 in a transmission manner, one end of the pull rope 5 penetrates through the top wall of the frame body 2 and is in sliding connection with the frame body 2, a limiting plate 6 is fixedly installed at the top end inside the frame body 2, a sleeve 7 is fixedly installed at the bottom of the limiting plate 6, a return spring 8 is fixedly installed inside the sleeve 7, a counterweight column 9 is inserted into the bottom end inside the sleeve 7, the counterweight column 9 is in sliding connection with the sleeve 7, the top of the counterweight column 9 is fixedly connected with the pull; the bottom of the counterweight column 9 is fixedly provided with a tamping plate 10, a solid block 11 is arranged below the frame body 2, and the solid block 11 is matched with the tamping plate 10 in size. Before the tamping, tighten up stay cord 5 through the hoist engine for counter weight post 9 acts on answer spring 8, makes answer spring 8 accumulate great elastic potential energy, then releases stay cord 5, and under the effect of the elasticity of answer spring 8 and the gravity of counter weight post 9 this moment, tamping plate 10 can produce great impact force to the ground, thereby reaches the tamping effect.
