Description

Technical Field

[0001] The utility model belongs to the technical field of ramming devices, and more specifically, particularly relates to a foundation ramming device. Background Technique

[0002] Before constructing a power civil engineering project, it is necessary to first use a ramming device to ram the foundation, so as to improve the strength of the foundation soil and reduce its compressibility. The existing ramming device drives an eccentric wheel to rotate through a motor, so that the mounting bracket drives a pressing plate to swing under the action of centrifugal force, and the foundation is rammed by the impact of the pressing plate on the soil.

[0003] For example, CN218233424U discloses a foundation ramming device, including a base and a moving seat slidably mounted on the base. A support seat is fixedly mounted on the top of the moving seat. A first motor is fixedly mounted on one side of the support seat. The output end of the first motor is fixedly connected with a crank. One end of the crank is rotatably connected with a connecting rod. The lower end of the connecting rod penetrates to the bottom of the moving seat and is rotatably connected with a connecting plate. A ramming plate is arranged at the bottom of the connecting plate. Both ends of the top of the base are fixedly mounted with support plates. A second motor is fixedly mounted on one side of the support plate. The output end of the second motor is fixedly connected with a screw rod. The moving seat is threadedly sleeved on the screw rod. In the utility model, through the arrangement of the second motor, the screw rod, the guide rod and the moving seat, during ramming, the position of the moving seat can be adjusted, and different positions can be rammed without manually moving the device frequently, which saves time and effort.

[0004] Based on the above, during the working process of the existing ramming device, the soil in the foundation easily falls above the pressing plate, and when the pressing plate swings, the soil will be brought into the base, and the base needs to be cleaned after use, which not only causes a large labor burden on the staff, but also takes a long time, affecting the use effect of the ramming device.
