Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of engineering construction, and in particular relates to a foundation tamping reinforcement device. Background Art
[0002] Dynamic compaction is a foundation reinforcement method that involves lifting a large-tonnage rammer to a certain height using a crane and then allowing it to fall freely. This powerful impact energy imparts to the foundation soil, thereby increasing the foundation's bearing capacity and reducing its compressibility. Dynamic compaction can also improve site uniformity, eliminate collapsibility and expansion, and prevent vibration liquefaction. However, this type of machinery is primarily used on large construction sites. Large-scale dynamic compaction equipment is not suitable for applications where construction areas meet surrounding mountainous terrain.
[0003] After searching, we learned that the patent application number is 201420334927.4, which is a utility model patent for a light rammer for soft foundation reinforcement. This patent does not require a trailer when in use, which improves the maneuverability of the equipment. The drop point of the rammer is set at the center of the frame, and is equipped with reinforcement columns, which makes it more stable during rammer operations. In addition, the drop force of the rammer can be adjusted by adjusting the height of the gantry. In summary, the rammer is a light rammer with a reasonable structure, easy use, good stability and maneuverability, and can be used at the junction of the construction area and the surrounding mountains.
[0004] However, some of these small dynamic compaction machines require repeated starting and stopping of the winch to reel in the rope, which is then used to hoist the rammer into the air and then bring it down. However, repeated starting and stopping of the winch can reduce the life of the motor inside the winch, accelerate rope wear, and lead to low compaction efficiency. Therefore, to address these issues, we designed a foundation dynamic compaction reinforcement device. Utility Model Content

[0025] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the embodiments. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0026] like Figure 1 As shown, a foundation compaction reinforcement device includes a vehicle body 1, a push handle rod 12 connected to the vehicle body 1, and a pair of base plates 11 provided on the vehicle body 1;
[0027] like Figure 2 and Figure 3 As shown, when implemented, it includes: a ramming assembly 2, which includes a connecting rod 1 21 rotatably arranged on both sides of the push handle frame rod 12, a turntable 23 rotatably arranged on the outer wall of each base plate 11, a connecting rod 22 arranged at the edge of the turntable 23 and rotatably connected to each connecting rod 1 21 at one end, a mounting rod 24 arranged in the ends of the two connecting rods 22, and a ramming piece 3 arranged on the mounting rod 24, and the ground foundation can be further leveled, reinforced and compacted by the ramming piece 3;
[0028] Specifically, a slot 241 for fitting the rammed earth piece 3 is provided on the mounting rod 24, and a plurality of fixing bolts 242 are provided on the side of the mounting rod 24. The rammed earth piece 3 includes a mounting plate 31 and a rammed earth block 32 provided on the mounting plate 31. The bottom surface of the rammed earth block 32 is an arc surface, and a plurality of assembly holes 311 for fitting the fixing bolts 242 are provided on the mounting plate 31. During installation, the mounting plate 31 on the rammed earth piece 3 is inserted into the slot 241 of the mounting rod 24, and the rammed earth piece 3 is fixed with a plurality of fixing bolts 242, so as to realize convenient disassembly and replacement.
[0029] like Figure 1 and Figure 2 As shown, the embodiment includes: a drive assembly 4, which includes a gear box 41 and a servo motor 42 arranged on the bottom plate of the vehicle body 1, a pair of meshing spiral bevel gears 1 411 and 2 412 arranged in the gear box 41, and a transmission shaft 43 rotatably arranged on the inner sides of a pair of base plates 11 and inserted into the gear box 41, and the spiral bevel gear 2 412 is sleeved on the transmission shaft 43;
[0030] Specifically, the shaft of the spiral bevel gear 411 passes through the gear box 41, and the end is connected to the main shaft end of the servo motor 42 through a coupling. By starting the servo motor 42 to provide power, the spiral bevel gear 411 and the spiral bevel gear 2 412 in the gear box 41 are driven to rotate. When the spiral bevel gear 2 412 rotates, the transmission shaft 43 and the turntables 23 on both sides are synchronously driven to rotate, thereby transmitting the power of the servo motor 42 to the turntables 23 on both sides; when the two turntables 23 rotate synchronously, each connecting rod 22 is driven to perform reciprocating uniform circular motion on each turntable 23. At this time, the connecting rod 1 21 is pulled, and the connecting rod 1 21 and the connecting rod 2 22 are synchronously linked to ensure the stability of the rammed earth assembly 2 during reciprocating motion.
[0031] like Figures 1 to 3 As shown, in this embodiment, it should be noted that the actual size of each component in the application document is selected and installed before implementation according to the actual needs of the site. The traction of the vehicle body 1 can be manually pushed by on-site personnel or by traction equipment. It is a matter of choice and is not limited in this embodiment. In addition, it should be noted again that this application document only addresses the existing small-scale dynamic compaction machine, which requires repeated starting and stopping of the winch to reel in the lifting rope, and uses the lifting rope to lift the rammer into the air for hammering. However, repeated starting and stopping of the winch may reduce the service life of the motor in the winch, accelerate the wear of the lifting rope, and have the disadvantage of low compaction efficiency. Improvements are made, and other improvements are not involved. The following is an introduction to the working principle of this foundation dynamic compaction reinforcement equipment:
[0032] During installation and use, on-site workers move the entire reinforcement equipment to the designated construction site / yard, start the servo motor 42 to provide power, drive the spiral bevel gear 1 411 and the spiral bevel gear 2 412 in the gear box 41 to rotate, and when the spiral bevel gear 2 412 rotates, the transmission shaft 43 and the turntables 23 on both sides are synchronously driven to rotate, thereby transmitting the power of the servo motor 42 to the turntables 23 on both sides;
[0033] When the two turntables 23 rotate synchronously, they drive each connecting rod 2 22 to perform uniform circular motion on each turntable 23. At this time, the connecting rod 1 21 is pulled, and the connecting rod 1 21 and the connecting rod 2 22 are synchronously linked to ensure the stability of the rammed earth assembly 2 during reciprocating motion. When each connecting rod 2 22 moves to the highest point of each turntable 23, the rammed earth piece 3 is lifted to the highest point. When each connecting rod 2 22 moves to the lowest point of each turntable 23, the rammed earth piece 3 drops to the lowest point and acts on the ground. Then, after the rammed earth assembly 2 has reciprocated multiple times, the rammed earth piece 3 further levels, reinforces and compacts the ground foundation. This new structure is simple and has a better compaction effect than traditional small compactors. It is especially suitable for single-person operation when compacting the foundation of a small house. There is no need to repeatedly start and stop the winch to reel in the lifting rope. It has the characteristics of low investment cost, high compaction efficiency and convenient operation.
[0034] The above embodiments are only used to illustrate the technical method of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the present invention.
