Abstract
Description
Technical Field
[0001] This invention relates to the field of foundation compaction technology, specifically to a foundation leveling and compaction device for building engineering. Background Technology
[0002] Foundation compaction is a core process in building construction to ensure the density, uniformity, and bearing capacity of the foundation, directly affecting the overall stability, settlement control, and service life of the building. Currently, construction sites commonly use equipment such as electric impact rammers, hydraulic compactors, and vibratory plate compactors for foundation compaction. While these methods achieve the desired foundation compaction, they suffer from the following insurmountable technical drawbacks in practical engineering applications: 1. Poor impact resistance of the drive mechanism leads to easy damage and short lifespan of the equipment. Most existing compaction equipment uses a motor or hydraulic direct drive to lift the hammer. The strong reaction force generated by the hammer falling freely and hitting the foundation is directly transmitted to core components such as the motor, lead screw, gears, and frame through the transmission mechanism. Long-term high-frequency impact can easily cause thread stripping, bearing breakage, frame deformation and cracking, and transmission failure, which not only significantly increases the equipment failure rate and maintenance costs, but also poses construction safety hazards. 2. Fixed compaction weight, unable to adapt to diverse foundation conditions. Conventional compaction equipment has a fixed hammer weight, which cannot be adjusted according to the thickness of the foundation soil layer, soil hardness, and base layer type. For scenarios such as weak soil layers, thin foundations, and soil layers over concrete cushions, excessively heavy hammers can easily cause base layer breakage and structural damage; for bearing layers with high compaction requirements, excessively light hammers cannot achieve the designed compaction degree, resulting in serious deficiencies in equipment versatility and construction flexibility. 3. The tamping hammer is severely sticky with mud and lacks an automatic cleaning function. Clay, silty soil, wet soil and other soil types are very easy to stick to the bottom surface of the tamping hammer during tamping, forming mud bags. Mud sticking will reduce the effective tamping area and tamping strength, resulting in uneven foundation surface and uneven density. Existing equipment requires manual stopping to remove the mud, which is inefficient, labor-intensive and affects the continuity of construction. 4. Poor stability of lifting transmission and insufficient compaction flatness: Traditional compaction mechanisms often use single screw, single guide rail or eccentric wheel drive, which has poor controllability of lifting stroke. The hammer is prone to swinging and tilting, resulting in offset of the compaction point and poor flatness of the foundation, making it difficult to meet the requirements of high-precision site flatness and uniform compaction.
[0003] Therefore, a new type of foundation leveling and compaction device with stable structure, high durability and wide adaptability is being developed to solve this type of defect. Summary of the Invention

[0013] This invention provides a device for leveling and compacting the foundation of building projects. Compared with existing technologies, it has the following advantages: (1) The foundation leveling and compaction device for this construction project combines the weight adjustment mechanism and the compaction lifting mechanism. The two mechanisms can be driven by the first and second threaded rods to make the second threaded cylinder and the first threaded cylinder rise and fall alternately, and drive the square frame and the hammer pressing seat to rise and fall to compact the foundation. The hammer pressing seat uses its own weight to fall and strike, reducing the overall reaction force on the weight adjustment mechanism and avoiding damage to the equipment caused by the weight adjustment mechanism being subjected to reaction force frequently. At the same time, when the hammer pressing seat rises, it can be used with the second arc block and the first arc block to vibrate the hammer pressing seat, thereby shaking off the mud at the bottom for easy subsequent use. The weight of the hammer pressing seat can also be adjusted by the rectangular seat and the counterweight column, which improves the applicability of the equipment.
[0014] (2) The foundation leveling and compaction device for this construction project has a vertical frame installed on the top of the load-bearing platform, and a retractable vertical plate and a first arc block are set on the inner side of the vertical frame. It is used in conjunction with the bow-shaped frame and the second arc block. The structure allows the second arc block to collide with the first arc block when the tamping seat rises, thereby using the concave sliding frame to drive the tamping seat to vibrate left and right to shake off the mud at the bottom, which is convenient for subsequent use and does not require cleaning by the staff. After the tamping seat reaches the top, the inner pressure inclined plate can squeeze the side pressure plate, thereby retracting the first arc block to the inner side of the vertical frame, which makes it convenient for the tamping seat to drive the bow-shaped frame to descend, and avoids the bow-shaped frame and the second arc block from colliding with the first arc block.
[0015] (3) The foundation leveling and compaction device for this building project has counterweight grooves at the front and rear of the tamping seat, and threaded positioning rods and circular plates are installed on the inner side of the counterweight grooves. It is used in conjunction with rectangular seats and counterweight columns. The setting of these structures can adjust the weight of the tamping seat by installing different numbers of counterweight columns on the inner side of the receiving circular groove when the foundation is thin or the foundation is covered with concrete. This can effectively avoid damage to the bottom concrete layer and the foundation during the tamping process, and improve the overall practicality and functionality of the equipment.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. 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.
[0019] Please see Figures 1-15 The present invention provides a technical solution: a foundation leveling and compaction device for building engineering, including a compaction lifting mechanism 2 installed inside a weight adjustment mechanism 1; Please refer to Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 The diagram illustrates the overall structure of the weight adjustment mechanism 1. The weight adjustment mechanism 1 includes a support platform 101. A protective box 102 is fixedly installed on the top of the support platform 101 through an opening. Roller cylinders 103 are installed on the front and rear sides of the bottom of the support platform 101. A motor 104, a servo motor, is fixedly installed on the top of the protective box 102 via a bracket. The output shaft of the motor 104 is fixedly connected to a first threaded rod 113 via a coupling. The bottom end of the first threaded rod 113 passes through the protective box 102 and is rotatably connected to the bottom of the inner cavity of the protective box 102 via a bearing. A second threaded rod 105 is rotatably connected between the top and bottom of the inner cavity of the protective box 102 via a bearing. Both the first threaded rod 113 and the second threaded rod 105 are reciprocating screws. Both the first threaded rod 113 and the second threaded rod 105 are fixedly connected to a meshing gear disk 106. The first threaded rod 113 and the second threaded rod 105 are driven synchronously in opposite directions or in the same direction through the meshing gear disk 106. The motor 104 drives the first threaded rod 113 to rotate, and the gear disk 106 drives the second threaded rod 105 to rotate synchronously, so that the first threaded cylinder 107 and the second threaded cylinder 108 rise and fall alternately, supporting the square frame 202 and the hammer seat 210, realizing continuous cyclic compaction. When the square frame 202 rises to the top, the arc-shaped pressure rod 112 squeezes the strip plate 205 to move laterally, so that the pressure plate 208 is disengaged from the support rod 109. The hammer seat 210 falls freely under its own weight to compact, and the counter-vibration force is not transmitted to the drive mechanism, realizing strong shock absorption protection. The surfaces of the first threaded rod 113 and the second threaded rod 105 are respectively threadedly connected to the first threaded cylinder 107 and the second threaded cylinder 108, and the first threaded cylinder 107 and the second threaded cylinder 108 are staggered vertically. The first threaded cylinder 107 and the second threaded cylinder 108 are fixedly connected to the two sides of the first threaded cylinder 107 and the second threaded cylinder 108. The top and bottom of the inner cavity of the protective box 102 are fixedly connected to the vertical guide frame 111. The opposite side of the first threaded cylinder 107 and the second threaded cylinder 108 are provided with concave guide grooves 110 that cooperate with the vertical guide frame 111. The front and rear of the bottom sides of the inner cavity of the protective box 102 are fixedly connected to the arc-shaped pressure rods 112. Vertical frames 114 are fixedly connected to the front and rear sides of the top of the load-bearing platform 101. Retractable vertical plates 115 are provided on both sides of the inner cavity of the vertical frame 114. Rectangular openings 116 are provided on both sides of the vertical frame 114, with several rectangular openings 116 arranged alternately on both sides. A first arc block 117, which cooperates with the rectangular opening 116, is fixedly installed on one side of the retractable vertical plate 115. A first spring 119 is fixedly installed between two retractable vertical plates 115. Hollow grooves 120 are provided on the upper and lower parts of both sides of the vertical frame 114. A side pressure plate 118 is fixedly connected to the top of the retractable vertical plate 115. One end of 18 passes through the hollow groove 120 and extends to the outside of the vertical frame 114. The top of the vertical frame 114 is slidably installed with a T-shaped baffle 136 that works with the retractable vertical plate 115 through an opening. After the two retractable vertical plates 115 are separated and extended out, the T-shaped baffle 136 is inserted between the two retractable vertical plates 115 to support the retractable vertical plates 115 and prevent the first arc block 117 from being squeezed and retracting. When it rises, it will first push the arc-shaped parts on both sides of the T-shaped baffle 136 to separate the T-shaped baffle 136 from the retractable vertical plate 115, and then squeeze the two retractable vertical plates 115 to close and retract. A retractable plate 121 is fixedly connected to the bottom end of the retractable vertical plate 115. One end of the retractable plate 121 passes through the hollow groove 120 and extends to the outside of the vertical frame 114. A positioning groove 122 is provided on the top of the retractable plate 121. A U-shaped sliding plate 123 is slidably installed on the inner side of the lower hollow groove 120. Both sides of the top of the U-shaped sliding plate 123 are fixedly connected to the plug-in block 124 that cooperates with the positioning groove 122. The plug-in block 124 is used to insert into the positioning groove 122 to achieve retraction and locking, ensuring that the hammer pressing seat 210 descends without interference. A second spring 135 is fixedly connected to the bottom of the U-shaped sliding plate 123, and the bottom end of the second spring 135 is fixedly connected to the bottom of the inner cavity of the vertical frame 114. Rectangular bases 126 are fixedly mounted on the front and rear sides of the bottom of the support platform 101 via brackets. Each rectangular base 126 has a receiving groove 127 on one opposite side, and several receiving grooves 127 are provided. A counterweight column 125 is provided inside the receiving groove 127. Threaded holes 129 are provided at the opposite ends of the front and rear counterweight columns 125. A polygonal groove 130 is provided at the other end of the counterweight column 125, and a magnetic sheet 131 is installed inside the polygonal groove 130. The inner cavities of the front and rear receiving grooves 127 are aligned. On one side, a pull rod 132 is slidably installed through an opening. One end of the pull rod 132 located inside the storage groove 127 is fixedly connected to a polygonal magnetic block 133 that works with the polygonal groove 130 and the magnetic sheet 131. The polygonal magnetic block 133 works with the polygonal groove 130 and the magnetic sheet 131 to achieve insertion, magnetic attraction, and twisting, thus completing the quick assembly and disassembly of the counterweight column 125. Smooth openings 134 are provided at the front and rear of both sides of the top of the support platform 101. Correction inclined plates 128 are fixedly connected to both sides of the bottom of the support platform 101.
[0020] Please refer to Figure 11 , Figure 12 , Figure 13 , Figure 14 and Figure 15 The diagram illustrates the overall structure of the tamping and lifting mechanism 2. The tamping and lifting mechanism 2 includes four lifting guide rods 201, which are located inside the protective box 102. A square frame 202 is fixedly connected between the top ends of the four lifting guide rods 201. The bottom ends of the lifting guide rods 201 penetrate the protective box 102 and extend to its bottom. Sliding grooves 203 are provided on both the front and rear sides of the inner side of the square frame 202. A horizontal sliding rod 204 is fixedly installed between the two sides of the inner cavity of the sliding groove 203. Between two sliding grooves 203 on the same side... A strip plate 205 is slidably installed. A third spring 206 is sleeved on the surface of the horizontal slide bar 204. A flip-up slot 207 is opened on the front and rear sides of the bottom of the strip plate 205. A pressure-bearing rotating plate 208 is rotatably installed on the inner side of the flip-up slot 207 through a rotating component. A fourth spring 209 is fixedly installed between the pressure-bearing rotating plate 208 and the bottom of the strip plate 205. The fourth spring 209 connects the pressure-bearing rotating plate 208 and the strip plate 205, so that the pressure-bearing rotating plate 208 is kept in a horizontal supporting state. It can be flipped downward to avoid obstacles, but cannot be flipped upward to disengage. An arched frame 219 is provided on the inner side of the smooth opening 134. A hammering seat 210 is fixedly connected between the bottom ends of the two arched frames 219. A concave sliding frame 211 is fixedly connected to the top of the hammering seat 210. The lifting guide rod 201 extends to one end of the bottom of the protective box 102 and is slidably connected to the concave sliding frame 211. A lifting groove 212 is provided on the top of the arched frame 219, and the vertical frame 114 is located inside the lifting groove 212. A second arc block 213 that cooperates with the first arc block 117 is fixedly installed on both sides of the inner cavity of the lifting groove 212. An inner pressure inclined plate 214 that cooperates with the side pressure plate 118 is fixedly connected to both sides of the top of the arched frame 219. The front and rear of the hammering base 210 are provided with counterweight grooves 215 that cooperate with the receiving circular groove 127 and the counterweight column 125. A threaded positioning rod 216 that cooperates with the counterweight column 125 and the threaded hole 129 is fixedly connected to one side of the inner cavity of the counterweight groove 215. A circular ring plate 217 is slidably installed on the inner side of the counterweight groove 215, and the circular ring plate 217 is sleeved on the surface of the threaded positioning rod 216. A fifth spring 218 is fixedly installed between the circular ring plate 217 and the inner wall of the counterweight column 125.
[0021] In use, the roller 103 is used to push the equipment to the foundation. Then, the weight of the hammering seat 210 is adjusted according to the foundation conditions. First, the pull rod 132 is pushed by hand to move the polygonal magnetic block 133 against the counterweight column 125, so that one end of the counterweight column 125 enters the inner side of the counterweight groove 215 and pushes the receiving groove 127. When the threaded hole 129 contacts the threaded positioning rod 216, the pull rod 132 is rotated, and the polygonal magnetic block 133 drives the counterweight column 125 to rotate as well. Then, the counterweight column 125 is threadedly connected to the threaded positioning rod 216 until the counterweight column 125 is completely inside the counterweight groove 215. Then, the pull rod 132 and the polygonal magnetic block 133 are pulled back to the inner side of the receiving groove 127. After several counterweight columns 125 are in place as required... After installation, the starter motor 104 uses two gear discs 106 to mesh, thereby driving the first threaded rod 113 and the second threaded rod 105 to rotate synchronously. Since the first threaded cylinder 107 and the second threaded cylinder 108 are staggered vertically, when the first threaded cylinder 107 rises, the second threaded cylinder 108 is in a descending state. Initially, the support rods 109 on both sides of the first threaded cylinder 107 contact the bottom of the pressure plate 208. Then, the first threaded cylinder 107, supporting the strip plate 205, the square frame 202, the lifting guide rod 201, and the hammer seat 210, rises synchronously. When the first threaded cylinder 107 drags the square frame 202 to the top, the second threaded cylinder 108 just reaches the bottom. Then, after the square frame 202 reaches the top, the two... The side arc-shaped pressure bar 112 uses its arc shape to compress the strip plate 205, causing the strip plates 205 on both sides to move in opposite directions through the sliding groove 203 and the horizontal sliding bar 204. The movement of the strip plates 205 causes the pressure-bearing rotating plate 208 to separate from the supporting rod 109. At the moment the pressure-bearing rotating plate 208 separates from the supporting rod 109, the hammer pressure seat 210 falls downwards to strike the foundation for compaction. When the hammer pressure seat 210 reaches the top, it also causes the bow-shaped frame 219 to rise until the inner pressure inclined plate 214 presses the side pressure plate 118, causing the two retractable vertical plates 115 and the first arc block 117 to retract to the inside of the vertical frame 114. At the same time, the insertion block 124 rises elastically through the second spring 135 and inserts into the inside of the positioning groove 122 to fix the retractable vertical plate 115. When the hammering seat 210 contacts the ground, the square frame 202 will not fall to the bottom of the protective box 102, but will only reach the top of the load-bearing platform 101. After the hammering seat 210 drives the bow-shaped frame 219 to the bottom, the bow-shaped frame 219 will press against both ends of the U-shaped slide plate 123, thereby causing the U-shaped slide plate 123 to drive the plug block 124 to descend and separate from the positioning groove 122. Then, the retracting vertical plate 115 pushes the first arc block 117 to both sides of the vertical frame 114 again through the elastic force of the first spring 119. While the first threaded cylinder 107 descends, the second threaded cylinder 108 rises. When the second threaded cylinder 108 rises to the top plane of the load-bearing platform 101, the support rods 109 on both sides of the second threaded cylinder 108 contact the bottom of the pressure rotating plate 208.Then, the second threaded cylinder 108, supporting the strip plate 205, the square frame 202, and the hammering seat 210, begins to rise again. When the square frame 202 rises and encounters the descending first threaded cylinder 107, the supporting rods 109 on both sides of the first threaded cylinder 107 press down on the pressure-bearing rotating plate 208, causing it to flip and pass through the flipping slot 207. This allows the first threaded cylinder 107 to pass through the square frame 202 and reach the bottom to continue descending. As the hammering seat 210 is driven to rise, the two second arc blocks 213 continuously interact with the first arc block. The first arc block 117 contacts the second arc block 219, causing the bow-shaped frame 219 to drive the tamping seat 210 to vibrate left and right under the guidance of the concave sliding frame 211, thus shaking off the mud at the bottom. This continues until the second arc block 213 reaches the top of the vertical frame 114 and no longer contacts the first arc block 117. However, both sides of the tamping seat 210 also contact the straightening inclined plates 128.
