Description

Technical Field

[0001] This invention relates to the field of construction equipment technology, specifically to an automatic rammer. Background Technology

[0002] The fire-powered ram is made based on the principle of a two-stroke internal combustion engine. There are two pistons in the cylinder, the upper piston is the internal combustion piston, and the lower piston is the buffer piston. The ramming hammer with an inclined bottom is mounted on the lower part of the cylinder, so that the vertical axis of the cylinder is tilted forward. The upper piston rod extends from the through hole in the middle of the cylinder top cover, and the lower piston rod extends from the lower end face of the cylinder and is connected to the ramming hammer. The cylinder and the ramming hammer are tensioned by a spring, and there is a handle to control the forward direction of the ram. Under the action of the combustion and explosion force of the combustible mixture, the fire-powered ram jumps forward and upward off the ground, and under the action of its own weight, it falls to the ground to ram the soil. With each jump and fall of the ramming hammer, the machine moves forward step by step.

[0003] However, when using existing fire rammers, if the ground soil is loose and damp, some soil will stick to the rammer feet when the rammer body is used to compact the ground. If the soil sticking to the rammer feet is not cleaned in time, it may cause the rammer feet to become unstable, thus affecting the stability of the equipment. In order to clean the soil from the rammer feet, the rammer body is usually stopped and the soil is removed manually. When the soil is removed manually, the machine is stopped, which not only increases the cleaning process but also reduces work efficiency due to the equipment stopping.

[0004] Based on this, the present invention designs an automatic rammer to solve the above problems. Summary of the Invention

This allows for cleaning during ascent without interfering with the tamping foot's descent, ensuring continued ground compaction. The coordinated operation of these components enables automatic cleaning of the tamping foot's bottom surface, eliminating the need for manual cleaning and preventing disruption to the equipment's operation. Furthermore, the coordinated components ensure that cleaning occurs after each compaction cycle, preventing excessive soil buildup on the tamping foot's bottom, which could lead to instability and affect the equipment's performance. Finally, the coordinated operation allows for continuous cleaning without requiring the equipment to be stopped. Attached Figure Description

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figures 1-6 The present invention provides a technical solution:

[0029] An automatic rammer includes a rammer body 1, a piston rod 6 slidably connected inside the rammer body 1, a fixed housing 7 mounted on the piston rod 6, a rammer foot 9 mounted at one end of the piston rod 6, a rotating column 10 rotatably connected inside the fixed housing 7, two first gears 11 mounted on the rotating column 10, two pairs of first racks 12 slidably connected inside the rotating column 10, the two first racks 12 meshing on the upper and lower sides of the first gears 11, a first spring 13 sleeved on the first racks 12, a connecting rod 14 fixedly connected between the two first racks 12, and two second springs 15 fixedly connected to the connecting rod 14. A scraper 16 is installed between the rotating column 10 and a torsion spring 17 is fitted on the rotating column 10. A first conical tooth 18 is installed at the other end of the rotating column 10. A groove 19 is opened in the ramming body 1. A slider 20 is slidably connected in the groove 19. A second gear 21 is provided on the slider 20. A second conical tooth 22 is provided on the second gear 21. A second rack 23 is provided in the ramming body 1. The second gear 21 and the second rack 23 are movably meshed. A reversing mechanism 24 is provided between the second conical tooth 22 and the first conical tooth 18. The reversing mechanism 24 includes a connecting column 25 and a third conical tooth 26. A third spring 29 is fitted on the piston rod 6.

[0030] The ramming body 1 is equipped with four gyroscopes 2, and a jet engine 3 is installed on the ramming body 1. The jet engine 3 is equipped with four jet pipes, and a jet head 4 is installed at one end of each jet pipe. The four jet heads 4 are located on the four sides of the ramming body 1. This facilitates the adjustment of the angle of the ramming body 1, prevents the ramming body 1 from tilting, and facilitates the movement of the ramming body 1.

[0031] The ramming body 1 is equipped with a stroke cylinder, and an exhaust port 5 is provided on one side of the ramming body 1. The exhaust port 5 is located below the stroke cylinder, and the piston rod 6 is slidably connected inside the stroke cylinder to facilitate the return movement of the piston rod 6.

[0032] Among them, a shock-absorbing pad 8 is provided between the ramming body 1 and the fixed shell 7. The shock-absorbing pad 8 is a rubber corrugated pad to reduce the vibration of the ramming body 1.

[0033] The first spring 13 is fixedly connected at one end to the fixed shell 7 and at the other end to the first rack 12. The second spring 15 is provided with a telescopic rod. One end of the telescopic rod is fixedly connected to the scraper 16 and the other end is fixedly connected to the connecting rod 14. The two scrapers 16 are installed opposite each other, and the scraper 16 and the tamping foot 9 are located on the same horizontal plane, which facilitates the cleaning of the tamping foot 9.

[0034] One end of the torsion spring 17 is fixedly connected to the rotating column 10, and the other end is fixedly connected to the fixed shell 7; this facilitates the reset and relocation of the scraper 16.

[0035] A limiting frame is provided between the connecting post 25 and the first conical tooth 18, and another limiting frame is provided between the connecting post 25 and the second conical tooth 22. A third conical tooth 26 is installed at both ends of the connecting post 25, and the two third conical teeth 26 mesh with the first conical tooth 18 and the second conical tooth 22 respectively; this facilitates the limiting of the connecting post 25.

[0036] The ramming body 1 is equipped with a handrail 27, the surface of which is covered with a rubber anti-slip layer. The ramming body 1 is also equipped with an oil injection pipe 28. The second gear 21 is a one-way gear, which allows the operator to operate the machine manually when the automatic function is not in use.

[0037] It also includes a remote-controlled vehicle, which can move in multiple directions after receiving commands. The middle part of the remote-controlled vehicle is fixedly connected to the ramming body 1. The ramming body 1 is also equipped with a control unit, which includes a data input module, a storage module, a comparison module, and an infrared scanning module. The data input module is used to input map information and import it into the storage module. The infrared scanning module is used to scan and obtain actual regional information and import the information into the comparison module. The comparison module is used to compare the information obtained by the infrared scanning module with the information stored in the storage module and issue working commands to the remote-controlled vehicle and the stroke cylinder.

[0038] Before starting work, the data input module of the control unit inside the tamping body 1 inputs the site map to be tamped into the storage module. The control unit inside the tamping body 1 identifies the required work site based on the site map in the storage module, strictly constrains the work boundary according to the site map, and places the remote control vehicle on the site to be tamped. The infrared scanning module first scans the actual information of the area and then transmits it to the comparison module. The comparison module compares the information transmitted by the infrared scanning module with the site map in the storage module. When they are the same, the comparison module controls the stroke cylinder to tampe. After tamping is completed, the comparison module controls the remote control vehicle to move forward a certain distance. By repeating the above operation, the tamping work can be completed autonomously.

[0039] Working principle:

[0040] The ramming body 1 is placed on the ground, with the ramming feet 9 in contact with the ground and the two scrapers 16 located on either side of the ramming feet 9. The stroke cylinder is then opened, causing the piston rod 6 to operate. When the piston rod 6 operates, the oil-gas mixture in the stroke cylinder is combusted, generating a force that causes the piston rod 6 to descend. Simultaneously, the third spring 29 is compressed. When the piston rod 6 slides to the appropriate position in the ramming body 1, the gas in the stroke cylinder is discharged through the exhaust port 5. At this time, the third spring 29 rebounds. When the third spring 29 rebounds, the piston rod 6 rises, and the ramming feet 9 move away from the ground. When the ramming feet 9 move away from the ground, the fixed shell 7 moves upward simultaneously. At this time, the second gear 21 rotates under the drive of the second rack 23, and the second conical tooth 22 rotates under the drive of the second gear 21. The amount of rotation of the second gear 21 is transmitted to the first bevel gear 18 through the third bevel gear 26 in the reversing mechanism 24. When the first bevel gear 18 rotates, the first gear 11 rotates. When the first gear 11 rotates, the two first racks 12 approach each other. At this time, the two scrapers 16 scrape off the soil on the ramming foot 9, and the torsion spring 17 is compressed. When the piston rod 6 moves to the upper side of the second rack 23, the second gear 21 and the second rack 23 disengage. The torsion spring 17 rebounds, which drives the first gear 11 to rotate in the opposite direction. When the piston rod 6 finishes its downward movement, the two scrapers 16 are still located on both sides of the ramming foot 9, thus repeatedly cleaning the ramming foot 9.

[0041] The first gear 11, first rack 12, first spring 13, scraper 16, first conical tooth 18, second conical tooth 22, second gear 21, second rack 23, and other parts of the equipment work together to clean the soil adhering to the bottom surface of the tamping foot 9 when it moves upward. When the tamping foot 9 descends, the two scrapers 16 return to their original positions on either side of the tamping foot 9. This allows for cleaning during ascent without interfering with the tamping foot 9 during descent, ensuring that the tamping foot 9 can still compact the ground. The coordinated operation of these parts enables the equipment to automatically clean the bottom surface of the tamping foot 9, eliminating the need for manual cleaning and preventing disruption to the equipment's operation. Furthermore, the coordinated movement of the parts ensures that cleaning occurs after each compaction, preventing excessive soil buildup on the bottom surface of the tamping foot 9, which could lead to instability and affect the equipment's performance.
