Description

Technical Field

[0001] The utility model relates to the technical field of construction equipment, in particular to a soil compacting device. Background Art

[0002] With the development of the construction industry and the full utilization of soft soil foundations, traditional foundation treatment is becoming more and more perfect, and new foundation treatment methods are constantly emerging. Cement soil compaction piles, as a new foundation treatment method, are more suitable for collapsible loess areas. During the treatment process, a heavy hammer compactor is required to compact the soil inside the pile hole.

[0003] The existing compacting machine mainly includes a lifting mechanism and a rammer. The lifting mechanism is used to lift the rammer, and then the rammer falls to the soil inside the pile hole by gravity, and the operation is repeated many times to compact the soil.

[0004] The shortcomings of the existing rammers are that the rammer of the existing rammer includes a hammer rod and a hammer head. Since the hammer head is repeatedly used for impact, it is easy to be damaged. Once damaged, it needs to be disassembled and repaired, and rammers of different sizes need to be replaced according to the compaction needs. The area compacted by the rammer at a single time depends on the size of the hammer head, so related disassembly and assembly operations are also required; there are generally two ways to connect the existing hammer head and the hammer rod. One is to weld them together directly. In this way, the entire rammer needs to be disassembled and separated. Since the overall weight of the rammer is heavy, the disassembly and assembly is difficult. The other is to use bolts and other connecting parts to fix the hammer head and the hammer rod. Although this method can remove the hammer head alone, the bolts and other connecting parts need to be rotated and twisted during the disassembly process, and the operation time is long, resulting in low disassembly and assembly efficiency. Utility Model Content

[0005] The utility model aims to provide a soil compacting device to solve the technical problem that the hammer head of the rammer in the soil compacting equipment in the prior art is not convenient for quick disassembly and assembly, and the disassembly and assembly efficiency is low.

[0006] The technical problem to be solved by the utility model can be achieved through the following technical solutions:

[0007] A soil compacting device comprises a mobile body, a lifting mechanism and a rammer, wherein the lifting mechanism is arranged on the mobile body, the rammer comprises a hammer column and a hammer head, the hammer head is arranged at the bottom of the hammer column, and the hammer column is connected to the lifting end of the lifting mechanism, and further comprises:

[0008] A docking card, the docking card is arranged on the upper side of the hammer head, the docking card comprises a docking tube and a docking block, the docking tube is fixedly arranged on the hammer head, and the inner diameter of the docking tube matches the outer diameter of the hammer column, a plurality of docking blocks are arranged, and they are circumferentially distributed on the docking tube, each of the docking blocks transversely penetrates the docking tube, a limiting spring is connected between the end of the docking block on the outer side of the docking tube and the outer wall of the docking tube, and an extrusion slope is arranged on the end of the docking block on the inner side of the docking tube;

[0009] An annular groove, which is arranged near the bottom of the hammer column and matches with the docking block;

[0010] A linkage separation component is arranged on the upper side of the docking cylinder, and one end of each docking block outside the docking cylinder is cooperatively connected with the linkage separation component.

[0011] As a further solution of the present invention: the linkage separation component includes a linkage ring and a linkage rod, the linkage ring is arranged in parallel above the docking tube, there are multiple linkage rods, and the linkage rods are distributed corresponding to the docking blocks, one end of each linkage rod is movably connected to the linkage ring through a hinge, and the other end is movably connected to the corresponding docking block through a hinge.

[0012] As a further solution of the utility model: the inner diameter of the linkage ring is equal to the outer diameter of the hammer column.

[0013] As a further solution of the utility model: a plurality of universal ball pieces are circumferentially arranged on the bottom edge of the hammer column.

[0014] As a further solution of the utility model: the sliding sleeve on the hammer column is provided with a protective sleeve.

[0015] Beneficial effects of the utility model:

[0016] 1. When disassembling the hammer head in the rammer of the utility model, the linkage ring is directly pressed down, and the linkage ring drives the docking blocks inserted in the annular groove to slide and separate by means of the distributed linkage rods, so that the hammer head can be quickly separated from the bottom of the hammer column. When installing a new hammer head, the hammer head is placed on the ground, and then the hammer column is aligned with the docking tube and inserted into the docking tube by gravity. During the insertion process, the bottom of the hammer column first squeezes the extrusion inclined surfaces at the ends of each docking block, causing the docking block to slide to the outside of the docking tube. When the docking block is aligned with the annular groove, each docking block is quickly inserted into the annular groove by means of the rebound force of the corresponding limit spring, so that the hammer head and the hammer column can be quickly docked. This facilitates rapid disassembly and assembly, and is convenient for replacing hammer heads of different sizes or overhauling hammer heads.

[0017] 2. The hammer column of the utility model is equipped with a protective sleeve, which is used to shield and protect the linkage separation component and the docking block to prevent external substances from acting on the linkage separation component and the docking block during the process of compacting the soil, thereby affecting the subsequent disassembly and assembly of the hammer head.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 1-Figure 3As shown, a soil compacting device comprises a mobile body 1, a lifting mechanism 2 and a rammer, the lifting mechanism 2 is arranged on the mobile body 1, the rammer comprises a hammer column 3 and a hammer head 4, the hammer head 4 is arranged at the bottom of the hammer column 3, and the hammer column 3 is connected to the lifting end of the lifting mechanism 2, the lifting mechanism 2 can select a winch, and the rammer is lifted by winding a steel wire rope, and then released, so that the rammer falls into the hole by gravity, compacts the soil at the bottom of the hole, and then lifts it again, and repeats this process to realize soil compaction. The device also comprises a docking card, an annular card groove 13 and a linkage separation component, the docking card is arranged on the upper side of the hammer head 4, the docking card comprises a docking tube 5 and a docking card block 9, and the docking The tube 5 is fixedly arranged on the hammer head 4, and the inner diameter of the docking tube 5 matches the outer diameter of the hammer column 3. A plurality of docking blocks 9 are arranged and circumferentially distributed on the docking tube 5. Each docking block 9 penetrates the docking tube 5 transversely. A limit spring 12 is connected between the end of the docking block 9 on the outside of the docking tube 5 and the outer wall of the docking tube 5. An extrusion slope 10 is arranged on the end of the docking block 9 on the inside of the docking tube 5. When the hammer column 3 is lowered and inserted into the docking tube 5, the bottom edge of the hammer column 3 squeezes the extrusion slope 10 at the end of each docking block 9. Each docking block 9 is pushed by the lateral component force, thereby sliding to the outside of the docking tube 5. During this process, the limit spring 12 is stretched to generate a rebound force.

[0025] The annular card groove 13 is provided near the bottom of the hammer column 3, and the annular card groove 13 cooperates with the docking card block 9. When the hammer column 3 is lowered and inserted into the docking tube 5, each docking card block 9 first slides toward the outside of the docking tube 5 due to extrusion. When the bottom of the hammer column 3 is completely inserted into the docking tube 5, the position of each docking card block 9 is exactly aligned with the position of the annular card groove 13. In this way, each docking card block 9 slides into the annular card groove 13 by relying on the rebound force released by the corresponding limit spring 12, so that the hammer head 4 and the hammer column 3 are docked, so that quick docking can be achieved conveniently.

[0026] The linkage separation component is arranged on the upper side of the docking tube 5, and one end of each docking card block 9 outside the docking tube 5 is cooperated with the linkage separation component. The linkage separation component allows all the docking card blocks 9 to move simultaneously out of the annular card groove 13 on the hammer column 3, so as to facilitate the rapid disassembly of the hammer head 4, thereby facilitating the replacement of the hammer head 4, and multiple hammer heads 4 of different sizes can be produced. Each hammer head 4 is provided with a docking card matching the hammer column 3, so as to facilitate the rapid disassembly and replacement of the hammer head 4 of the corresponding size, so as to facilitate the compaction of the soil inside the hole of the corresponding size.

[0027] It should be noted that the above-mentioned linkage separation component includes a linkage ring 7 and a linkage rod 8. The linkage ring 7 is arranged in parallel above the docking tube 5. The inner circle diameter of the linkage ring 7 is equal to the outer diameter of the hammer column 3, which is convenient for the linkage ring 7 to be fitted on the docked hammer column 3, so that the linkage ring 7 can slide up and down smoothly along the hammer column 3. There are multiple linkage rods 8, and the linkage rods 8 are distributed corresponding to the docking card blocks 9. One end of each linkage rod 8 is movably connected to the linkage ring 7 through a hinge, and the other end is movably connected to the corresponding docking card block 9 through a hinge. When it is necessary to disassemble and separate the hammer head 4 from the hammer column 3, the linkage ring 7 is pressed down, and the linkage ring 7 squeezes the linkage rod 8 downward, and the linkage rod 8 drives the distributed docking card blocks 9 to slide and be pulled out to the outside of the docking tube 5, so that the docking card block 9 is separated from the annular groove 13, thereby facilitating the separation of the hammer head 4 from the hammer column 3.

[0028] In some specific implementation schemes, in order to facilitate relative sliding when the hammer column 3 squeezes the extrusion inclined surface 10 at the end of the docking block 9, so that the docking block 9 moves laterally, a plurality of universal ball pieces 11 are circumferentially arranged on the bottom edge of the hammer column 3. The universal ball piece 11 includes a spherical shell and a sphere. The spherical shell is fixed on the hammer column 3, and the sphere is movably embedded in the spherical shell. In this way, when the hammer column 3 descends to squeeze the extrusion inclined surfaces 10 at the ends of each docking block 9, the bottom of the hammer column 3 slides relatively between the distributed universal ball pieces 11 and the extrusion inclined surfaces 10.

[0029] In some specific implementation schemes, in order to prevent external substances from acting on the linkage separation component and the docking block 9 during the rammer compacting soil, thereby affecting the subsequent disassembly and assembly of the hammer head 4, a protective sleeve 6 is slidably mounted on the hammer column 3. When the hammer head 4 and the hammer column 3 are docked together, the protective sleeve 6 is lowered along the hammer column 3 so that its bottom end contacts the hammer head 4, thereby providing shielding and protection for the linkage separation component and the docking block 9.

[0030] In order to facilitate the understanding of the embodiments of this solution by those skilled in the art, the working principle of this solution is briefly described in combination with specific application scenarios:

[0031] When it is necessary to replace the hammer head 4 of different sizes in order to compact the soil at the bottom of the hole of corresponding size, or to inspect and replace the hammer head 4, the linkage ring 7 above the originally installed hammer head 4 is first pressed downward, and the linkage ring 7 presses the linkage rod 8 downward, and the linkage rod 8 drives the distributed docking blocks 9 to slide out of the docking tube 5, so that the docking blocks 9 are separated from the annular groove 13 provided at the bottom of the hammer column 3, so that the hammer head 4 is separated from the hammer column 3;

[0032] Then place the new hammer head 4 on the ground, and rely on the mobile body 1 to drive the lifted hammer column 3 to move above the new hammer head 4, and then make the bottom of the hammer column 3 align with the docking tube 5 on the upper side of the hammer head 4 and descend. When the hammer column 3 descends and inserts into the docking tube 5, the bottom edge of the hammer column 3 squeezes the extrusion slope 10 at the end of each docking block 9, and each docking block 9 is pushed by the lateral component force, thereby sliding toward the outside of the docking tube 5. During this process, the limit spring 12 is stretched to generate a rebound force. When the bottom of the hammer column 3 is completely inserted into the docking tube 5, the position of each docking block 9 is exactly aligned with the position of the annular groove 13. In this way, each docking block 9 relies on the rebound force released by the corresponding limit spring 12 to slide into the annular groove 13, so that the hammer head 4 and the hammer column 3 are docked, so that quick docking can be achieved conveniently.

[0033] Several embodiments of the utility model are described in detail above, but the embodiments of the utility model are not limited thereto and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
