Description

Technical Field

[0001] This invention relates to the field of building construction, specifically to a gravity-based reciprocating foundation compaction device for civil engineering construction. Background Technology

[0002] A tamping machine is a type of machinery that uses a crane to lift a hammer to a certain height and then uses the impact energy of free fall to repeatedly tamp and compact the surface of the foundation soil, forming a relatively dense hard shell layer, thereby reinforcing the foundation. It is suitable for reinforcing foundations of slightly moist cohesive soil, sandy soil, collapsible loess, miscellaneous fill, and layered fill soil that are more than 0.8m above the groundwater level.

[0003] Common compaction machines compact the ground by impacting it with a heavy hammer. The hammer generates a strong impact force when it falls. When there are stones in the area to be compacted, the impact force of the falling hammer will knock the stones away or squeeze them away. If there is no obstruction, the stones may injure nearby construction workers. Summary of the Invention

[0004] The purpose of this invention is to provide a gravity-based reciprocating foundation compaction device for civil engineering construction, so as to solve the problems mentioned in the background art.

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

A first support block is fixedly mounted on the end of the sliding rod away from the top plate to support it. The first support block is fixedly mounted on the mounting frame. A counterweight block for compacting the foundation is provided on one side of the top plate. Sliding parts that slide on the sliding rods are fixedly mounted on both sides of the counterweight block.

[0008] A vehicle body is fixedly installed on the side of the mounting bracket away from the top plate, and a drive assembly for moving the counterweight is installed on the vehicle body.

[0009] A protective baffle is provided on the side of the mounting bracket away from the top plate. Multiple movable blocks that are slidably connected to the slide rod are fixedly installed on the protective baffle. A lifting assembly connected to the protective baffle is installed on the vehicle body.

[0010] The vehicle is equipped with a cleaning component to remove mud from the bottom of the counterweight.

[0011] As a further aspect of the present invention: the sliding member includes a limiting slider fixedly installed on both sides of the counterweight and sliding on the sliding rod. The limiting slider has an installation cavity, and multiple arc-shaped rollers are rotatably connected between the inner walls of the two sides of the installation cavity. The arc-shaped rollers are distributed on both sides of the sliding rod and abut against the sliding rod.

[0012] As a further embodiment of the present invention: the drive assembly includes a circular hole in the top plate, and first support frames fixedly installed on the top plate and arranged opposite each other on both sides of the circular hole. A second support frame is fixedly installed on the vehicle body. Rollers are rotatably connected between the end of the second support frame away from the vehicle body and the two first support frames on both sides. Cables are placed on the two rollers.

[0013] As a further embodiment of the present invention: two opposing third support blocks are fixedly installed on the vehicle body, and a winch is rotatably connected between the two third support blocks. One side of the winch's shaft extends to the other side of one of the third support blocks and a second gear is fixedly installed thereon. One end of the cable is wound around the winch, and the other end of the cable passes through a round hole and is fixedly installed with a counterweight.

[0014] As a further embodiment of the present invention: a servo motor is fixedly installed on the vehicle body, a third gear is fixedly installed on the output shaft of the servo motor, two opposing second support blocks are fixedly installed on the vehicle body, a broken-tooth gear that meshes with the second gear is rotatably connected between the two second support blocks, one side of the broken-tooth gear extends to the other side of one of the second support blocks and a first gear is fixedly installed thereon, and the first gear meshes with the third gear.

[0015] As a further embodiment of the present invention: the lifting assembly includes a connecting rod disposed on one side of the mounting frame, the connecting rod being rotatably connected to a limiting block supporting it, the limiting block being fixedly mounted on the mounting frame, one end of the connecting rod being fixedly mounted to a protective baffle, the other end of the connecting rod being fixedly mounted to a push plate, a telescopic rod being fixedly mounted on the vehicle body, the side of the push plate away from the connecting rod being fixedly mounted to the movable end of the telescopic rod, a compression spring sleeved on the telescopic rod being abutted between the push plate and the vehicle body, and an electromagnet being fixedly mounted in the fixed section of the telescopic rod.

[0016] As a further embodiment of the present invention: a lifting rod is fixedly installed on one side of the push plate, and a retaining ring that engages with the second gear is fixedly installed on the side of the lifting rod away from the push plate.

A hinge seat is installed between the cleaning plate and the movable end of the electric telescopic rod.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention has a novel design. The movable end of the downward-moving telescopic rod drives the push plate on one side to move downward. The moving push plate pushes the connecting rod fixed to it to move downward, while simultaneously pressing against the compression spring below to compress it. The moving connecting rod pushes the lower protective baffle to press against the ground. The protective baffle prevents the counterweight from hitting the ground and knocking stones flying. When the protective baffle is not in contact with the ground, the retaining ring will abut against the second gear, causing the equipment to malfunction. Conversely, when the protective baffle descends and presses against the ground, the retaining ring will move away from the second gear, and the equipment can work normally, thus enhancing the safety of the equipment.

[0028] 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.

[0029] Furthermore, elements in this invention are referred to as being "fixed to" or "set on" another element, which may be directly on the other element or may also include an intervening element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or may also include an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.

[0030] Please see Figure 1 , Figure 2 In this embodiment of the invention, a gravity-based reciprocating foundation compaction device for civil engineering construction includes:

[0031] Mounting frame 2, on which a top plate 3 is fixedly mounted. Two opposing sliding rods 5 are fixedly mounted on one side of the top plate 3. A first support block 4 is fixedly mounted on the end of the sliding rod 5 away from the top plate 3 to support it. The first support block 4 is fixedly mounted on the mounting frame 2. A counterweight block 9 for compacting the foundation is provided on one side of the top plate 3. Sliding parts that slide on the sliding rods 5 are fixedly mounted on both sides of the counterweight block 9.

[0032] Please see Figure 6The sliding component includes a limiting slider 6 fixedly installed on both sides of the counterweight 9 and sliding on the slide rod 5. The limiting slider 6 has an installation cavity, and multiple arc-shaped rollers 19 are rotatably connected between the inner walls of the two sides of the installation cavity. The arc-shaped rollers 19 are distributed on both sides of the slide rod 5 and abut against the slide rod 5.

[0033] The limiting sliders 6 on both sides of the counterweight 9 ensure that the downward direction of the counterweight 9 remains consistent. The multiple arc-shaped rollers 19 connected to the limiting sliders 6 allow the limiting sliders 6 to slide more smoothly on the slide bar 5. If the limiting sliders 6 are directly fitted onto the slide bar 5 without using the arc-shaped rollers 19, the counterweight 9 will generate greater friction when rising or falling, increasing the resistance of the counterweight 9. In particular, when the counterweight 9 falls, the high-speed downward movement of the counterweight 9 causes the limiting sliders 6 and the slide bar 5 to rub against each other. This high-speed friction generates extremely high heat, and prolonged operation under such conditions will reduce the service life of the slide bar 5. However, by using the arc-shaped rollers 19, the friction is greatly reduced, allowing the equipment to be used for a longer period of time.

[0034] The mounting bracket 2 is fixedly mounted on the side away from the top plate 3, and a vehicle body 1 is installed on the vehicle body 1 to drive the counterweight 9 to move upward.

[0035] Please see Figure 1 , Figure 2 , Figure 5 The drive assembly includes a circular hole on the top plate 3. A first support frame 10 is fixedly installed on the top plate 3 and arranged opposite to each other on both sides of the circular hole. A second support frame 12 is fixedly installed on the vehicle body 1. A roller 13 is rotatably connected between the end of the second support frame 12 away from the vehicle body 1 and the first support frames 10 on both sides. A cable 11 is placed on the two rollers 13.

[0036] Specifically, the first support frame 10 and roller 13 fixedly installed on the top plate 3 cause the cable 11 to be stretched downwards, allowing it to pass through the round hole and pull on the object below. The second support frame 12 fixedly installed on the vehicle body 1 and the roller 13 thereon prevent the cable 11 from contacting the top plate 3 below when stretched, thus avoiding the possibility of the cable 11 breaking.

[0037] Please see Figure 2 , Figure 4 , Figure 5Two opposing third support blocks 21 are fixedly installed on the vehicle body 1. A winch 22 is rotatably connected between the two third support blocks 21. One side shaft of the winch 22 extends to the other side of one of the third support blocks 21 and a second gear 23 is fixedly installed thereon. One end of the cable 11 is wound around the winch 22, and the other end of the cable 11 passes through a round hole and is fixedly installed with the counterweight 9.

[0038] In detail, the second gear 23 rotates, which drives the winch 22 on one side to rotate. When the winch 22 rotates forward, it pulls the cable 11 to wind around the winch 22. The cable 11, which is pulled backward, pulls the counterweight 9 below to rise. Of course, when the second gear 23 is released, the counterweight 9 slides down due to gravity, and the weight of the counterweight 9 compacts the ground.

[0039] Please see Figure 3 , Figure 4 , Figure 5 A servo motor 14 is fixedly installed on the vehicle body 1. A third gear 28 is fixedly installed on the output shaft of the servo motor 14. Two opposing second support blocks 16 are fixedly installed on the vehicle body 1. A broken gear 15 that meshes with the second gear 23 is rotatably connected between the two second support blocks 16. One side of the broken gear 15 extends to the other side of one of the second support blocks 16 and a first gear 20 is fixedly installed thereon. The first gear 20 meshes with the third gear 28.

[0040] When the servo motor 14 is in operation, the output shaft of the servo motor 14 drives the third gear 28 fixed to it to rotate. The rotating third gear 28 drives the first gear 20 meshing with it to rotate. The rotating first gear 20 drives the broken-tooth gear 15 coaxial with it to rotate. The rotating broken-tooth gear 15 drives the second gear 23 meshing with it to rotate. Of course, because the broken-tooth gear 15 has a missing tooth, when the missing tooth part of the broken-tooth gear 15 rotates to the meshing point with the second gear 23, the second gear 23 is not stuck, so the second gear 23 will rotate in the opposite direction due to the slippage of the counterweight 9.

[0041] The mounting bracket 2 is provided with a protective baffle 7 on the side away from the top plate 3. Multiple movable blocks 8 are fixedly installed on the protective baffle 7 and slidably connected to the slide rod 5. A lifting assembly connected to the protective baffle 7 is installed on the vehicle body 1.

[0042] Please see Figure 3 , Figure 8The lifting assembly includes a connecting rod 17 disposed on one side of the mounting frame 2. The connecting rod 17 is rotatably connected to a limiting block that supports it. The limiting block is fixedly installed on the mounting frame 2. One end of the connecting rod 17 is fixedly installed to the protective baffle 7. The other end of the connecting rod 17 is fixedly installed to a push plate 18. A telescopic rod 26 is fixedly installed on the vehicle body 1. The side of the push plate 18 away from the connecting rod 17 is fixedly installed to the movable end of the telescopic rod 26. A compression spring 27 sleeved on the telescopic rod 26 abuts against the push plate 18 and the vehicle body 1. An electromagnet 32 ​​is fixedly installed in the fixed section of the telescopic rod 26.

[0043] Specifically, when electromagnet 32 ​​is energized, it generates magnetic force, pulling the movable end of the upper telescopic rod 26 downward. Of course, an iron plate is fixed on the movable end of the telescopic rod 26. The downward movement of the movable end of the telescopic rod 26 drives the push plate 18 on one side to move downward. The moving push plate 18 pushes the connecting rod 17 fixed to it to move downward, while pressing against the compression spring 27 below to compress it. The moving connecting rod 17 pushes the protective baffle 7 below to press against the ground. The protective baffle 7 prevents the counterweight 9 from hitting the ground and knocking stones flying. Of course, when not in use, electromagnet 32 ​​is de-energized, and the compressed spring 27 pushes the push plate 18 on one side back to its original position.

[0044] Please see Figure 3 , Figure 4 A lifting rod 25 is fixedly installed on one side of the push plate 18, and a toothed ring 24 that engages with the second gear 23 is fixedly installed on the side of the lifting rod 25 away from the push plate 18.

[0045] In detail, when the push plate 18 rises, the rising push plate 18 drives the lifting rod 25 on one side to move upward. The moving lifting rod 25 pushes the retaining ring 24 fixed thereon to abut against the second gear 23, so that the second gear 23 cannot rotate. Through the above structure, the retaining ring 24 will only move away from the second gear 23 when the protective baffle 7 descends and touches the ground, and the equipment can work normally. Of course, if the protective baffle 7 does not contact the ground, the retaining ring 24 will abut against the second gear 23, causing the equipment to stop operating.

[0046] Please see Figure 5 , Figure 7 The cleaning assembly includes an electric telescopic rod 29 mounted on the vehicle body 1. The electric telescopic rod 29 is fixedly mounted on the vehicle body 1 by a buckle. A cleaning plate 31 for cleaning the bottom of the counterweight 9 is provided on one side of the electric telescopic rod 29. A hinge seat 30 is installed between the cleaning plate 31 and the movable end of the electric telescopic rod 29.

[0047] The cleaning plate 31 is moved by the electric telescopic rod 29, which pushes up the soil that is stuck on the counterweight block 9 due to the compaction of the ground. This prevents the ground from sinking due to excessive residual soil when the counterweight block 9 continues to compact the ground.

[0048] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0049] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
