Technical Field

[0001] This invention relates to the field of dynamic compaction machine technology, and in particular to an automated dynamic compaction machine with navigation function. Background Technology

[0002] A dynamic compaction machine is a machine used in construction projects to compact loose soil.

[0003] The rammer is quite heavy. During the lifting process, the weight at the front of the dynamic compaction machine suddenly increases, which makes the machine prone to tilting forward. When the rammer is lifted to a certain height and released from the hook, the weight at the front of the machine suddenly decreases, causing the boom to be subjected to a huge reaction force and sway backward, making the machine unstable. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an automated dynamic compaction machine with navigation function.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

One end of the lifting rope is connected to a hook, the lower end of the hook is movably connected to a connector, and the lower end of the connector is fixed with a tamping hammer.

[0007] A connecting frame is installed at one end of the machine body, and a connecting plate is fixed at one end of the connecting frame. Reinforcing ribs are symmetrically fixed at the corners on the inner side of the connecting plate. An electric hydraulic rod is installed below the connecting plate.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] 1. The motor drives the drive gear to rotate clockwise, and the two driven gears rotate counterclockwise accordingly.

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0027] Reference Figure 1-5An automated dynamic compaction machine with navigation function includes a body 1, tracks 2, boom 3, support frame 4, and lifting rope 5. One end of the lifting rope 5 is connected to a hook 6, and the lower end of the hook 6 is movably connected to a connector 7. A tamping hammer 8 is fixed to the lower end of the connector 7. A connecting frame 9 is installed at one end of the body 1, and a mounting plate 10 is fixed to one end of the connecting frame 9. The mounting plate 10 is fixed to the body 1 by bolts 11. This structure enables the installation of the connecting frame 9 and the body 1. A connecting plate 12 is fixed to one end of the connecting frame 9. Reinforcing ribs 13 are symmetrically fixed at the corners on the inner side of the connecting plate 12. An electric hydraulic rod 14 is installed below the connecting plate 12. A first fixing plate 15 is fixed to the lower end of the electric hydraulic rod 14. A second fixing plate 27 is provided below the first fixing plate 15. An anchoring mechanism is installed below the second fixing plate 27. The anchoring mechanism includes a housing 28. A motor 29 is installed inside the housing 28. The output end of the motor 29 is connected to a first rotating shaft 30. One end of the housing 20 is fixed with a drive gear 31, and driven gears 33 are meshed on both sides of the drive gear 31. A second rotating shaft 35 is fixed above the driven gears 33. A fixing rod 36 is fixed inside the housing 28. The second rotating shaft 35 is rotatably connected to the fixing rod 36 through a bearing. A first anchor rod 32 is fixed below the drive gear 31, and a second anchor rod 34 is fixed below the driven gears 33. When the motor 29 is started, the motor 29 drives the drive gear 31 to rotate clockwise through the first rotating shaft 30. The two driven gears 33 then rotate counterclockwise. The first anchor rod 32 and the two second anchor rods 34 rotate clockwise and counterclockwise respectively, and indirectly drive the housing 28 to move slowly downward through the electro-hydraulic rod 14, so that the first anchor rod 32 and the second anchor rod 34 gradually screw into the ground. The bottom surface of the housing 28 is in contact with the ground. Then the motor 29 and the electro-hydraulic rod 14 are turned off, so that the anchoring mechanism can be stably supported at the front end of the machine body 1, ensuring the stability of the machine body 1.

[0028] The first fixed plate 15 is connected to the second fixed plate 27 via an adjustment mechanism. The adjustment mechanism includes a support column 16 and a connector 17. The connector 17 is fixedly connected to the second fixed plate 27, and a connecting shaft 18 is fixedly connected between the two connectors 17. The connecting shaft 18 is rotatably connected to the support column 16. A retaining seat 19 is fixed to one end of the connecting shaft 18. A spring 21 is connected to one side of the support column 16. A moving plate 22 is fixed to one end of the spring 21. A retaining block 23 is fixed to one side of the moving plate 22 at a position corresponding to the retaining seat 19. Protrusions 24 are evenly distributed on the side of the retaining block 23. The inner side of the retaining seat 19 has a protrusion that corresponds to the protrusion. The slot 20 that matches block 24 gradually pulls block 23 out of the seat 19, and protrusion 24 no longer engages with slot 20. At this time, spring 21 is stretched by external force. After block 23 is completely disengaged from seat 19, connector 17 can be rotated until the bottom surface of housing 28 is as parallel to the ground as possible. Then, align protrusion 24 with slot 20 one by one, and slowly release handle 25. Under the elastic force of spring 21, block 23 re-enters seat 19, and uses the engagement of protrusion 24 with slot 20 to fix connector 18, that is, connector 17 and housing 28.

[0029] Through holes are provided at the bottom of the housing 28 at the positions corresponding to the first anchor rod 32 and the second anchor rod 34. The threads of the two second anchor rods 34 have the same direction, while the threads of the first anchor rod 32 and the second anchor rod 34 have opposite directions. The threads of the first anchor rod 32 and the second anchor rod 34 should be consistent with the rotation direction of the driving gear 31 and the driven gear 33, respectively.

[0030] A handle 25 is fixed on one side of the movable plate 22, and a limit rod 26 is fixed on the other side of the movable plate 22. A limit groove is opened on one side of the support column 16. The limit rod 26 is slidably connected to the limit groove. The limit rod 26 plays a limiting role on the movable plate 22, so that the movable plate 22 can only move in the horizontal direction.

[0031] A heat dissipation vent is provided on the surface of the housing 28 at the position corresponding to the motor 29. The opening of the heat dissipation vent is beneficial to the heat dissipation of the motor 29.

[0032] After moving the dynamic compaction machine to the designated position, start the motor 29. The motor 29 drives the drive gear 31 to rotate clockwise via the first rotating shaft 30, and the two driven gears 33 rotate counterclockwise accordingly. The first anchor rod 32 and the two second anchor rods 34 rotate clockwise and counterclockwise respectively, and indirectly drive the housing 28 to move slowly downwards via the electro-hydraulic rod 14. If the ground at the designated position is not flat enough, stop the motor 29 and the electro-hydraulic rod 14, hold the handle 25 by hand, and gradually pull the locking block 23 out of the locking seat 19. The protrusion 24 will no longer engage with the slot 20. At this time, the spring 21 is stretched by external force, and the limiting rod 26 limits the movement of the moving plate 22, so that the moving plate 22 can only move horizontally. After the locking block 23 is completely disengaged from the locking seat 19, the connecting piece 17 can be rotated until the bottom surface of the housing 28 is as parallel as possible to the ground. Next, align the protrusions 24 with the slots 20 one by one, and slowly release the handle 25. Under the elastic force of the spring 21, the block 23 re-enters the seat 19. The setting of the protrusions 24 and the slots 20 can enhance the fixing effect of the block 23 on the seat 19. After adjustment, restart the motor 29 and the electric hydraulic rod 14, so that the first anchor rod 32 and the second anchor rod 34 gradually screw into the ground, and the bottom surface of the box 28 is in contact with the ground. Then turn off the motor 29 and the electric hydraulic rod 14. When the hammer 8 is lifted, the sudden increase in weight at the front end of the boom 3 can prevent the machine body 1 from tilting forward due to the support of the box 28. When the hammer 8 is unhooked and falls, the sudden decrease in weight at the front end of the boom 3 can prevent the machine body 1 from swaying backward under the reaction force due to the anchoring effect of the first anchor rod 32 and the second anchor rod 34, which greatly improves the stability of the machine body 1.

[0033] A GNSS antenna 37 is installed on connector 7, and a tension sensor 38 is installed on the suspension rope 5. The machine body 1 is equipped with a cab, which contains a Beidou GNSS satellite navigation module and a vehicle-mounted integrated controller. The GNSS antenna 37, tension sensor 38, Beidou GNSS satellite navigation module, and vehicle-mounted integrated controller are electrically connected. The Beidou GNSS satellite navigation module collects the position coordinates of the dynamic compaction machine in real time, and calculates the spatial position information of the hammer 8 through the geometric relationship between connector 7 and the Beidou GNSS satellite navigation module. When the offset of the dynamic compaction machine exceeds the allowable value, the vehicle-mounted integrated controller issues a corresponding walking command to adjust the vehicle's attitude and automatically walk to the corresponding position until the offset requirement is met before starting work. Tension sensor 38 monitors the force on the hoisting rope 5 in real time. When the hammer 8 is lifted, tension sensor 38 triggers the maximum threshold, sends a command to the vehicle-mounted integrated controller, and records the position of GNSS antenna 37 at this time, which is then calculated to obtain the lowest position of hammer 8. When hammer 8 is lifted to its highest point and hook 6 releases connector 7, the force on tension sensor 38 decreases sharply, triggering the minimum threshold. At this time, it also sends a command to the vehicle-mounted controller, records the position information of GNSS antenna 37 at this time, and calculates the highest position of hammer 8. When hammer 8 is lifted, tension sensor 38 triggers the maximum threshold, sends a command to the vehicle-mounted integrated controller, and records the position of GNSS antenna 37 at this time. When hammer 8 falls again and connector 7 lifts hammer 8 again, the hoisting rope 5 will be tensioned, and the position information of GNSS antenna 37 at this time will be recorded. The height difference between the two spatial position information of GNSS antenna 37 is the depth of the soil compacted by hammer 8 in one fall.
