Description

Technical Field

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

[0002] Ground compaction is an important part in building construction. Its purpose is to make the foundation compact and firm through compaction, improve the bearing capacity and stability of the foundation. The degree of foundation compaction needs to be uniform to avoid local looseness and ensure the overall stability of the foundation. Currently, most commonly used compaction equipment uses a compaction hammer to improve the stability of the foundation by compaction. For example, Chinese patent CN116837820B discloses a compactor for civil engineering. When the compactor is performing soil tamping operations, the worker pulls the compactor backward to compact the soil that has just been improved, and controls the extension and retraction of the hydraulic telescopic rod. The hydraulic extension pulls up the loose-screen-tamping integrated tamping head through the hydraulic head buckle and then presses it down to perform soil tamping. When the hydraulic telescopic rod is extended, the downward force is transmitted to the loose-screen-tamping integrated tamping head through the main shock-absorbing spring to improve the compaction effect. However, the compactor lacks a detection device and cannot detect the compaction degree of the soil. In actual operation, the compaction does not meet the standard.

[0003] Therefore, in view of the above problems, a soil compaction device for foundation construction is proposed to solve the above problems. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention develops a soil compaction device for foundation construction, which can compact the soil and detect the compaction condition of the soil at the same time.

[0005] The technical solution to the technical problem solved by the present invention is: a soil compaction device for foundation construction using a compaction method, comprising an outer shell, a compaction hammer disposed inside the outer shell, a handle disposed outside the outer shell, a compaction hammer disposed inside the outer shell, the compaction hammer connected to a driving structure, a detection structure disposed inside the compaction hammer, the detection structure connected to a water suction hose, a ground slide symmetrically disposed outside the outer shell, a mounting frame disposed on the ground slide, and a soil compensation structure disposed on the mounting frame.

[0006] The driving structure drives the compacting hammer to move, and the compacting hammer strikes the ground. The detection structure arranged in the compacting hammer strikes the ground to detect the hardness of the ground to ensure that the ground is compacted. The water on the ground is absorbed and discharged through the suction pipe to reduce the influence of the accumulated water on the compaction effect. The soil compensation structure of the mounting frame fills the soil on both sides of the device.

[0007] Preferably, the compacting hammer member includes a hammer block, which is slidably connected in the stopper of the outer shell. A boss is arranged on the hammer block, which cooperates with the stopper. An extrusion block is arranged on the hammer block, a driving structure is arranged above the extrusion block, and a hammer spring is arranged on the extrusion block. The two ends of the hammer spring are respectively connected to the hammer block and the inner wall of the outer shell.

[0008] The boss of the hammer block cooperates with the stopper to prevent the hammer block from falling off. The hammer spring arranged on the extrusion block stores energy and then releases it, driving the hammer block to hammer the ground multiple times, thereby improving the compaction effect.

[0009] Preferably, the driving structure includes a hammering ball, a groove is arranged on the extrusion block, the hammering ball cooperates with the groove of the extrusion block, the hammering ball is connected to the hammering hydraulic cylinder, and the hammering hydraulic cylinder is located on the outer shell.

[0010] The hammer hydraulic cylinder pushes the hammer ball to move, and the hammer ball passes through the extrusion block to make the hammer block compact the ground. The grooves arranged on the extrusion block increase the contact area of ​​the hammer ball, reduce the local pressure of the hammer ball hitting the extrusion block, and extend the service life of the extrusion block.

[0011] Preferably, the detection structure includes a down-pressure tube and a detection tube. The detection tube is slidably connected in the down-pressure tube. The down-pressure tube is passed through the middle part of the hammer block and the extrusion block. The down-pressure tube is connected to the hammer ball. A detection spring is arranged in the down-pressure tube. The two ends of the detection spring are respectively connected to the down-pressure tube and the detection tube. A conical end is arranged below the detection tube.

[0012] When the hammer ball moves downward, it drives the downward pressure tube to move. The downward pressure tube pushes the detection tube downward through the detection spring, and the compaction condition of the soil is detected by the depth of the detection tube inserted into the soil.

[0013] Preferably, the detection structure also includes an electric ring and springs. The electric ring is arranged in the hammer block. Multiple springs are arranged on the electric ring. Multiple connecting pieces are arranged on the outside of the detection tube. When the springs are in contact with the connecting pieces, the power is turned on and the indicator light is on. The indicator light is located outside the outer shell.

[0014] When the detection tube penetrates to a certain depth in the soil, the connector on the detection tube connects with the spring piece, lighting the indicator light to inform the operator that the ground compaction degree is poor.

[0015] Preferably, a plurality of water suction holes are arranged on the outer wall of the detection tube, a plurality of drainage ports are arranged on the outer wall of the down-pressure tube, a water delivery cavity is arranged in the extrusion block, the water delivery cavity is connected with the drainage port, the water delivery cavity is connected with the water suction hose, and the water suction hose is connected with the water pump.

[0016] When there is water accumulation on the ground, start the water pump, and the water pump draws water through the suction pipe. The accumulated water enters the detection pipe through the suction port, and then flows into the down-pressure pipe through the detection pipe, and flows into the suction pipe through the down-pressure pipe drainage port and the water delivery cavity and is discharged.

[0017] Preferably, the soil compensation structure includes a scraping motor, a connecting shaft and scraping blades. The scraping motor is arranged on the mounting frame, and a plurality of scraping blades are arranged outside the connecting shaft.

[0018] The motor drives the connecting shaft and the scraper blade to scrape the soil, pushing the soil to both sides of the equipment for soil compensation, improving the flatness of the ground and preventing a drop in the soil on both sides.

[0019] Preferably, the soil compensation structure further comprises a mounting tube, which is arranged on a ground slide plate, wherein a lower portion of the mounting tube is connected to the ground, an extrusion tube is slidably connected inside the mounting tube, and a detection column is slidably connected inside the extrusion tube.

[0020] Preferably, a compression spring is arranged in the extrusion cylinder, and the two ends of the compression spring are respectively connected to the extrusion cylinder and a detection column, the detection column is in contact with the ground, and a micro switch is arranged in the extrusion cylinder, and the micro switch controls the scraping motor on the same side.

[0021] When the soil on both sides of the equipment is soft or there is a drop, the detection column moves downward under the action of the compression spring. At this time, the extrusion cylinder moves downward, and the extrusion cylinder and the micro switch are disengaged. At this time, the motor starts and drives the scraper to rotate to compensate for the soil.

[0022] The effects provided in the content of the invention are only the effects of the embodiments, rather than all the effects of the invention. The above technical solution has the following advantages or beneficial effects: The driving structure drives the compacting hammer to move, and the compacting hammer hits the ground. The detection structure set in the compacting hammer detects the hardness of the ground to ensure that the ground is compacted. The water on the ground is absorbed and discharged through the water suction pipe to reduce the impact of the accumulated water on the compaction effect. The soil compensation structure of the mounting frame fills the soil on both sides of the device. When the hammer ball moves downward, it drives the pressure tube to move. The pressure tube pushes the detection tube downward through the detection spring. The soil compaction condition is detected by the depth of the detection tube inserted into the soil. When the detection tube penetrates to a certain depth in the soil, the connecting piece on the detection tube connects with the spring piece, and the indicator light is lit to inform the operator that the ground compaction degree is poor. When there is water accumulation on the ground, start the water pump, and the water pump pumps water through the water suction pipe. The accumulated water enters the detection pipe through the water suction port, and then flows into the down-pressure pipe through the detection pipe, and then flows into the water suction pipe through the drainage port and water delivery cavity of the down-pressure pipe and is discharged; When the soil on both sides of the equipment is soft or there is a drop, the detection column moves downward under the action of the compression spring. At this time, the extrusion cylinder moves downward, and the extrusion cylinder and the micro switch are disengaged. At this time, the motor starts and drives the scraper to rotate to compensate for the soil. BRIEF DESCRIPTION OF THE DRAWINGS
