Technical Field

[0001] The invention relates to a foundation dynamic compaction construction device and a control system thereof, belonging to the technical field of foundation dynamic compaction construction devices. Background Art

[0002] A dynamic compactor is a machine used to compact loose soil in construction projects. There are many types of dynamic compactors, and all types of dynamic compactors complete the compaction process by impacting and compacting the loose soil with the hammer columns on the dynamic compaction base.

[0003] Each time the hammer column of the existing dynamic compaction machine is lifted upward and then falls freely to compact the foundation, only one impact can be achieved. However, the impact compaction of a foundation point requires countless upward lifting of the hammer column, which is obviously inefficient. How to ensure that each time the hammer column falls to compact the foundation can generate multiple impact waves, so that the number of compaction times of the dynamic compaction machine can be reduced, thereby improving construction efficiency, is an urgent problem to be solved. In response to the above needs, the present invention proposes a foundation dynamic compaction construction device and a control system thereof. Summary of the Invention

It rises vertically in the lifting slide arm. When the telescopic assembly rises to a fixed high position, it cooperates with the push seat to perform automatic hooking operation, allowing the multiple hammer core assembly to fall freely as a whole to hammer the foundation. The strong vibration sensor on the synchronized multiple hammer core assembly has a strong vibration sensing function, which enables the control system to cut off the power to the electromagnetic suction cup body at the right time, causing the free fall of the first hammer core component and the second hammer core component to collide with the hammer column group, providing multiple conducted shock waves for the hammer column group, so that each fall of the multiple hammer core assembly has multiple forces to strongly compact the foundation, thereby effectively reducing the number of strong compaction times for a foundation point and improving construction efficiency.

[0026] The lifting and telescopic assembly 62 includes a lifting and pulling seat 621, and a plurality of supporting slide rod openings 622 are vertically opened on the four sides of the top surface of the lifting and pulling seat 621, and a telescopic lifting rod slide opening 623 is opened through the middle of the left side of the lifting and pulling seat 621, and a lifting rod 624 and a return spring 625 are movably sleeved in the telescopic lifting rod slide opening 623.

[0027] The bottom surface of the push seat 64 is provided with a push wheel running slope 641 for pushing the push wheel 627 after it rises vertically, so that the lifting rod 624 is retracted in the opposite direction of the lifting handle 525.

[0028] The control system 8 is electrically connected to the dynamic compaction construction device 2 and fixedly mounted on the upper end of the lifting frame body 3 . The other end of the control system 8 is electrically connected to an operating console fixedly mounted in the cab of the mobile vehicle 1 .

[0029] Working principle: When the foundation is strongly compacted, the compaction construction device 2 is moved to the construction site by the mobile vehicle 1, and the lifting frame body 3 is used for adjusting the height when compacting the ground, so that the hammer head 513 can always be in contact with the ground. When in use, the control system 8 is used as the overall control, and the oil cylinder 61 on the first lifting mechanism 6 and the second lifting mechanism 7 is first synchronously lowered to drive the lifting and telescopic assembly 62 to descend vertically. Under the action of the return spring 625, the second oblique section 626 and the two oblique sections of the first oblique section 526 are pushed to realize the automatic hooking of the lifting rod 624 and the lifting handle 525. Then, when the oil cylinder 61 rises synchronously, the control system 8 will control the electromagnetic suction cup body 542 to pass through the hydraulic cylinder 61. When the two lifting and telescopic components 62 are lifted vertically, they will first lift the first hammer core piece 52 and the second hammer core piece 53 in a linked manner. When the first hammer core piece 52 rises, the pressure spring 524 will be compressed. After the top surface of the first hammer core piece 52 rises to abut against the electromagnetic suction cup body 542 to establish an electromagnetic connection, the two lifting and telescopic components 62 continue to rise, which will be linked to the hammer column group 51 to rise vertically in the lifting slide 42, thereby realizing the multi-linked lifting operation of the first hammer core piece 52, the second hammer core piece 53, and the hammer column group 51 on the multiple hammer core assembly 5 in the lifting slide 4 by the first lifting mechanism 6 and the second lifting mechanism 7. Figure 2 .

[0030] When the lifting and telescopic assembly 62 rises vertically to roll against the push seat 64, the pressure wheel 627 will slide outward on the pressure wheel walking slope 641, so that the lifting rod 624 will retract in the opposite direction of the lifting handle 525, so that the lifting rod 624 and the hook of the lifting handle 525 are separated, and the hammer column group 51 is allowed to fall freely in the lifting slide 42 to hammer the foundation. This is the first hammering. When the hammer column group 51 hammers the foundation, the strong vibration sensor 55 will synchronously sense the strong vibration generated by the hammer column group 51, thereby transmitting a signal to the control system 8, and the control system 8 issues an instruction to the electromagnetic suction cup body 542 to electromagnetically cut off the power. The rope 532 is initially in a loose state, so the bottom surface of the second hammer core piece 53 will first hit the bottom of the second lifting hammer slot 5112 to provide the first shock wave to the hammer column group 51, and realize the second hammering of the hammer column group 51 to the foundation. At the same time, the first hammer core piece 52 will fall freely and accelerate its descent under the action of the elastic force released by the pressure spring 524, so that the bottom surface of the first hammer core piece 52 hits the bottom of the first lifting hammer slot 5111 to provide the second shock wave to the hammer column group 51, and realize the third hammering of the hammer column group 51 to the foundation, thereby realizing that each fall of the multiple hammer core assembly 5 can have the coordinated cooperation of direct impact on the foundation and conduction hammering of multiple shock waves.
