Description

Technical Field

[0001] This utility model relates to the field of ground construction technology, and more specifically, to a ground construction compaction device. Background Technology

[0002] A rammed earth machine is a compaction machine that uses impact and vibration to compact backfill soil in layers. During ground construction, rammed earth equipment is needed to compact the ground.

[0003] A search revealed that utility model patent CN218880799U discloses a ground compaction device, including a support frame and a drive motor. A threaded shaft is rotatably connected to the inner side of the support frame, and a lifting plate is helically connected to the outer side of the threaded shaft. A sliding rod is slidably connected to the inner side of the lifting plate, and a support plate is fixedly connected to the lower end of the sliding rod. The drive motor is fixedly connected to the lower end of the support plate, and a compaction base is fixedly connected to the lower end of the drive motor. A shrink sleeve is fixedly connected between the drive motor and the compaction base. Four casters are rotatably connected to the lower end of the support frame, symmetrically arranged about the central axis of the support frame. Rotation of the threaded shaft allows the lifting plate to rise and fall, which in turn moves the sliding rod up and down, allowing the height of the compaction base to be adjusted. This facilitates rapid movement of the compaction device or operation of the compaction work, improving the efficiency of ground compaction. However, the above patent still has the following shortcomings: Although the universal wheels can be used to move the device, when continuously compacting the ground, the device needs to be moved continuously, which is not very convenient to use. In addition, the stability of the device is not good when using the universal wheels to support it during compaction. Therefore, we have proposed a ground construction compaction device. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide a ground construction compaction device.

[0005] To solve the above problems, the present invention adopts the following technical solution:

[0006] A ground compaction device includes a support frame with a movable groove on the support frame. Slide grooves are respectively provided on both sides of the inner cavity of the movable groove. A screw is rotatably connected to the inner cavity of the movable groove. A movable seat is threaded onto the outer side of the screw. Both ends of the movable seat are movably sleeved into the inner cavity of the slide groove. A servo motor is fixedly installed at the end of the support frame. The output shaft of the servo motor is connected to the end of the screw. An electro-hydraulic rod is fixedly installed on the bottom surface of the movable seat. A compaction seat is fixedly connected to the bottom end of the electro-hydraulic rod. Multiple support mechanisms are provided on the bottom surface of the support frame.

[0007] As a preferred embodiment of this utility model, the support mechanism includes two support columns fixedly connected to the bottom surface of the support frame, a support plate fixedly connected to the bottom end of the two support columns, a through hole on the support plate, a U-shaped frame fixedly connected to the top surface of the support plate, an electric telescopic rod fixedly installed on the U-shaped frame, and the output end of the electric telescopic rod extending to the inner side of the U-shaped frame and fixedly connected to a moving wheel.

[0008] In a preferred embodiment of this utility model, a power supply box is fixedly connected to the top surface of the support frame, and a storage battery is installed inside the power supply box.

[0009] As a preferred embodiment of this utility model, push handles are fixedly installed on both sides of the support frame.

[0010] As a preferred embodiment of this utility model, a control panel is fixedly installed on the side of the support frame.

[0011] In a preferred embodiment of this utility model, the top and bottom surfaces of the two ends of the movable seat are respectively fitted with the top and bottom surfaces of the inner cavity of the slide groove.

[0012] Compared with existing technologies, the advantages of this utility model are:

[0013] (1) In this utility model, the electric hydraulic rod drives the compaction seat to move up and down, and the compaction seat is used to compact the ground. In addition, the servo motor drives the screw to rotate, and the position of the moving seat, the electric hydraulic rod and the compaction seat are adjusted by the threaded engagement between the screw and the moving seat, so as to adjust the compaction position of the compaction seat. At the same time, the problem of needing to move the compaction equipment continuously is avoided, and the practicality of the ground construction compaction equipment is improved.

[0014] (2) In this utility model, when the device needs to be moved, the electric telescopic rod is used to drive the moving wheel to extend to the lower part of the support plate to support the device so as to push the device to move. When the ground is compacted, the electric telescopic rod is used to drive the moving wheel to move upward so that the bottom surface of the support plate contacts the ground. The support plate and support column support the support frame, while ensuring the stability of the compaction equipment when it is working, thus improving the practicality of the ground construction compaction equipment.
