Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to a foundation compacting device for building construction. Background Art

[0002] Currently, foundation laying is required before civil construction. Since the civil construction foundation is relatively soft after laying, in order to make the civil construction foundation more solid, the foundation is compacted by a compaction device. By compacting the soil, the density and bearing capacity of the soil are increased to ensure that the building or structure can be firmly built on the foundation. By compaction, the compressibility of the soil is reduced, thereby reducing the problem of settlement after the building is built.

[0003] A foundation compacting device for civil engineering disclosed in Chinese patent CN115198721A includes a frame, a tamping head frame, an eccentric hammer and a driving mechanism, wherein one right end of the tamping head frame is rotatably mounted on the frame around a first rotating shaft extending forward and backward; the eccentric hammer includes a center wheel, a weight, a weight and an adjustment assembly, wherein the center of the center wheel is rotatably mounted on the tamping head frame around a second rotating shaft extending forward and backward, and the weight is fixed to the edge of the center wheel; the driving mechanism drives the center wheel to rotate around the second rotating shaft along the first direction, and the weight drives the tamping head frame to move upward and left intermittently while rotating with the center wheel, so that the tamping head frame compacts the ground when it falls back to the ground; the weight The sliding part is installed in the weight pendulum. When the weight pendulum swings above the second rotating shaft, the weight slides towards the second rotating shaft under the action of gravity, so that the center of gravity of the weight pendulum is close to the second rotating shaft, thereby reducing the force that moves the ram head frame to the right when the weight pendulum rotates; when the weight pendulum swings below the second rotating shaft, the weight slides away from the second rotating shaft under the action of gravity, so that the center of the weight pendulum is away from the second rotating shaft, thereby increasing the force that moves the ram head frame to the left when the weight pendulum rotates; the adjustment component adjusts the distance that the weight slides away from the second rotating shaft, thereby adjusting the center of gravity of the weight when it swings below the second rotating shaft; wherein the first direction is the counterclockwise direction viewed from front to back.

[0004] However, compared with the prior art and the comparative scheme, it can be seen that the foundation compaction device still has the following problems in actual use: When the existing frog-type rammer is working, the eccentrically arranged heavy pendulum drives the rammer frame to swing up and down to tamp the ground. There is a certain inclination angle when the rammer plate at the bottom of the rammer frame contacts the ground, so that the ground compacted by the rammer plate has a certain inclination angle each time, resulting in relatively poor flatness after tamping, which affects the foundation compaction effect. Summary of the invention

The second rack 342 and the first rack 333 are both transmission-connected to the tooth tube 315 through the gear 314.

[0028] The working process is as follows: S1. When in use, the driving member 4 is started, the driving member 4 drives the first transmission wheel 6, the first transmission wheel 6 drives the second transmission belt 10 to rotate through the first transmission belt 9, the second transmission belt 10 drives the third transmission wheel 8 to rotate through the connecting shaft 5, the third transmission wheel 8 drives the fourth transmission wheel 22 to rotate through the second transmission belt 10, and the fourth transmission wheel 22 drives the heavy pendulum 23 to rotate on the connecting frame 21; S2, during the rotation of the fourth transmission wheel 22 with the heavy swing 23, the centrifugal force generated drives the connecting frame 21 to swing back and forth on the connecting shaft 5, and the connecting frame 21 drives the compacting mechanism 3 to compact the building foundation; S3, when the heavy pendulum 23 rotates downward with the fourth transmission wheel 22, since the horizontal height of the second tamping plate 331 is greater than the horizontal height of the first tamping plate 321, the horizontal height of the third tamping plate 341 is equal to the horizontal height of the second tamping plate 331, and the first tamping plate 321 tamps the ground at the position corresponding to the first tamping plate 321; S4. When the first tamping plate 321 contacts the ground, the connecting seat 311 rotates in the through slot 25 via the rotating shaft 312, so that the first tamping plate 321 fits the ground, thereby ensuring the flatness of the tamped ground. At the same time, after the first tamping plate 321 contacts the ground, the connecting frame 21 continues to move downward due to the centrifugal force of the weight pendulum 23, the sliding shaft 322 slides in the tooth tube 315, and the second elastic member 323 contracts. S5. After the tooth tube 315 contacts the first tamping plate 321, the tooth tube 315 stops moving, the connecting seat 311 continues to move downward along with the connecting frame 21, the first elastic member 317 stretches, the tooth tube 315 drives the first rack 333 and the second rack 342 to move downward through the gear 314, and the first rack 333 and the second rack 342 respectively drive the second tamping plate 331 and the third tamping plate 341 to move downward relative to the connecting seat 311; S6, the connecting seat 311 is still moving downward with the connecting frame 21, increasing the downward moving speed of the second tamping plate 331 and the third tamping plate 341, and the second tamping plate 331 and the third tamping plate 341 tamp the ground; S7, when the heavy pendulum 23 rotates upward with the fourth transmission wheel 22, the connecting frame 21 swings upward, the tamping mechanism 3 leaves the ground, the first elastic member 317 and the second elastic member 323 rebound, driving the first tamping assembly 32, the second tamping assembly 33 and the third tamping assembly 34 to reset; S8. Push the equipment forward by the handrail 11, and the second compacting plate 331 pre-compacts the ground. By setting the inclined surface 332, when the second compacting plate 331 moves toward the ground, the gravel on the ground is pushed away. As the equipment moves, the first compacting plate 321 compacts the ground pre-compacted by the second compacting plate 331. As the equipment continues to move, the third compacting plate 341 compacts the ground again after being compacted by the first compacting plate 321, thereby improving the effect of compacting the foundation.
