Description

Technical Field

[0001] The utility model relates to the technical field of construction equipment, in particular to a compaction device for pipeline backfill construction. Background Art

[0002] In pipeline construction projects, after the pipeline laying operation is completed, the excavated soil needs to be backfilled into the pipeline trench to make the compactness and stability of the backfill meet the construction requirements. After backfilling the soil, generally, the backfill needs to be compacted and its surface made flat. At present, when compacting the backfill, construction workers usually only use tools to pat the soil, which is not only time-consuming and laborious, but also the compaction effect of the backfill is relatively poor. Summary of the Invention

[0003] The problem to be solved by the utility model is to provide a compaction device for pipeline backfill construction, which can effectively compact the backfill and ensure the compactness and stability of the pipeline backfill. The technical scheme adopted is as follows:

[0005] During use, after the construction workers complete the pipeline laying operation and backfill the soil into the pipeline trench, they adjust the distance between the two compaction mechanisms through the translation adjustment mechanism, and then drive the two compaction mechanisms to vibrate simultaneously through the vibration motor, so that the compaction mechanisms compact the backfill.

[0006] As a preferred scheme of the utility model, the translation adjustment mechanism includes a driving motor and a lead screw. The driving motor is arranged on the main frame body, the lead screw is rotatably installed on the main frame body in the horizontal direction, and one end of the lead screw is in transmission connection with the output shaft of the driving motor; a guide rail parallel to the lead screw is arranged on the main frame body, and the lead screw is provided with a positive thread section and a reverse thread section; the two compaction mechanisms are respectively threadedly connected to the positive thread section and the reverse thread section of the lead screw and can translate along the guide rail. When it is necessary to adjust the distance between the two compaction mechanisms, the driving motor is started to rotate the lead screw, so that the two compaction mechanisms respectively located on the positive thread section and the reverse thread section move towards or away from each other along the guide rail.

[0007] As a further preferred solution of the present utility model, the ramming mechanism includes a moving seat, a connecting plate and a pressing plate. A threaded hole matching the threaded section of the lead screw is provided on the moving seat. The moving seat is threadedly connected to the corresponding positive threaded section or reverse threaded section on the lead screw through the threaded hole, and the moving seat is slidably matched with the guide rail. The upper end of the connecting plate is connected to the moving seat, and the pressing plate is horizontally arranged at the lower end of the connecting plate. During use, the two pressing plates are respectively attached to the surfaces of the backfill soil on both sides of the pipeline. Driven by the vibration motor, the two pressing plates vibrate simultaneously to vibrate and compact the surfaces of the backfill soil on both sides of the pipeline.

[0008] In order to enable the pressing plate to fit the surfaces of the backfill soil at different heights, as a preferred solution of the present utility model, a height adjustment mechanism is further provided on the main frame body.

[0009] As a further preferred solution of the present utility model, the height adjustment mechanism includes two fixing frames, and the upper parts of the two fixing frames are respectively connected to the left and right sides of the main frame body. Slots are respectively provided on the front and rear sides of the fixing frame, and a support plate that slides up and down is installed in the slots.

[0010] As a further preferred solution of the present utility model, threaded holes communicating with the slots are provided on the fixing frames, at least one threaded hole corresponds to each slot, and limit bolts are installed in the threaded holes. The end of the limit bolt is in close contact with the surface of the support plate. After adjusting the height position of the support plate in the slot, lock the limit bolt to adjust the installation height of the pressing plate on the fixing frame.

[0011] In order to facilitate the movement of the device, as a further preferred solution of the present utility model, universal wheels are provided at the lower end of the support plate.

[0012] In order to facilitate the handling and moving operation of the device, as a preferred solution of the present utility model, a fixing ring is provided in the middle of the main frame body. A pulling rope is connected to the fixing ring. One end of the pulling rope is connected to the fixing ring, and the other end of the pulling rope is connected to a pulling ring. Buckle one end of the pulling rope on the fixing ring, and the entire device can be pulled through the pulling ring at the other end of the pulling rope. One end of the pulling rope can be connected to the fixing ring through a climbing buckle.

[0013] Compared with the prior art, the present utility model has the following advantages:

[0014] The pipeline backfill soil construction ramming device of the present utility model adjusts the distance between the two ramming mechanisms through the translation adjustment mechanism, and then drives the two ramming mechanisms to vibrate simultaneously through the vibration motor, so that the ramming mechanism compacts the backfill soil. It is not only convenient to operate, but also can effectively ram the backfill soil. The ramming area and effect are relatively good, ensuring the density and stability of the pipeline backfill soil. Description of the Drawings
