Description

Technical Field

[0001] This utility model belongs to the field of foundation pit backfilling and compaction technology, specifically a large-section pipe backfilling vibratory compactor. Background Technology

[0002] A vibratory compactor is a type of engineering machinery used for compaction operations. Its working principle involves a vibrator inside its steel wheel that generates vibrations. This vibrator is typically a device that makes circular motions. When the vibrator rotates at high speed, it causes the steel wheel to generate a vertically downward vibratory force. These forces are transmitted to the soil or paving material to achieve the compaction effect.

[0003] However, in reality, due to the special nature of the working environment, compacting the ground also raises a lot of dust. This dust not only affects the health of the workers but also obstructs their vision. These problems undoubtedly affect the progress of the project, the safety of the workers, and the safety of the construction.

[0004] Meanwhile, patent specification CN 219555638 U discloses a soil compactor for afforestation, including a compactor body and a vertical plate. The surface of the compactor body is fixedly connected to the end of the vertical plate. The compactor body is rotatably connected to a cam via a bearing. A pulley is fixed to the outer wall of the cam. A tightening mechanism is provided inside the compactor body. A first motor in the tightening mechanism drives a worm gear to rotate, which in turn drives a worm wheel to rotate, and the worm wheel drives a connecting column to rotate.

[0005] However, in implementing the relevant technology, the following problems were found in the above-mentioned soil compactor for afforestation: due to the special working environment of the compactor, it will raise a lot of dust when working. At the same time, since the utility model lacks a dust suppression device, workers will inhale a lot of dust and have their vision obstructed when working. Utility Model Content

[0006] To address the problems mentioned in the background section, this invention provides a large-section pipe backfill vibratory compactor with the advantage of efficient dust suppression. This invention solves the problem of dust generation during ground compaction in existing technologies, while also preventing workers from inhaling dust, thus ensuring worker safety and construction safety.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a large-section pipe backfill vibratory compactor, comprising a compactor body, a base plate fixedly installed inside the compactor body, a motor fixedly installed on the top surface of the base plate, a main gear fixedly installed at the end of the main shaft of the motor, a first driven gear meshing with the outer teeth of the main gear, and the first driven gear being rotatably connected to the compactor body, a second driven gear meshing with the outer teeth of the first driven gear, and the second driven gear being rotatably connected to the compactor body, a threaded rod fixedly installed on the outer side of the second driven gear, a first moving block threadedly connected to the outer side of the threaded rod, a metal water pipe installed inside the first moving block, and multiple nozzles fixedly installed at the bottom of the metal water pipe.

[0008] Preferably, another threaded rod is fixedly disposed on the outside of the first gear, and a second movable block is threadedly connected to the outside of the other threaded rod, and another metal water pipe is disposed on the outside of the second movable block.

[0009] Preferably, a water inlet pipe is fixedly installed on the rear side of the first movable block, a water tank is fixedly installed on the other side of the water inlet pipe, and another water inlet pipe is fixedly installed on the rear side of the second movable block.

[0010] Preferably, a water pipe is fixedly installed on the rear side of the water tank, a water distribution pipe is fixedly installed at the bottom of the water pipe, and multiple water outlets are fixedly installed on the bottom surface of the water distribution pipe, with the water outlets penetrating the compactor body.

[0011] Preferably, a vibrating wheel is rotatably mounted on the bottom surface of the compactor body, and the vibrating wheel is located below the water outlet.

[0012] Preferably, the first movable block has multiple locking blocks slidably disposed inside, and the locking blocks are engaged with the metal water pipe.

[0013] Preferably, a fixed shaft is fixedly provided inside the first movable block, a spring is sleeved on the outside of the fixed shaft, a connecting shaft is fixedly provided on the outside of the spring, the fixed shaft slides inside the connecting shaft, and the connecting shaft is fixedly connected to the locking block.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention introduces water from the tank into the first and second moving blocks via a water pipe. A motor then drives the main gear, which in turn rotates the first and second driven gears and their external threaded rods. The threaded rods move the first and second moving blocks, spreading water in front of the compactor body as they move. This wets the ground, reducing dust during operation and solving the problem of dust flying during compaction in existing technologies. It also prevents workers from inhaling dust, ensuring worker safety and overall construction safety. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1 to 5As shown, this utility model provides a large-section pipe backfill vibratory compactor, including a compactor body 1. A base plate 2 is fixedly installed inside the compactor body 1. A motor 3 is fixedly installed on the top surface of the base plate 2. A main gear 4 is fixedly installed at the end of the main shaft of the motor 3. A first driven gear 5 is meshed with the outer teeth of the main gear 4, and the first driven gear 5 is rotatably connected to the compactor body 1. A second driven gear 6 is meshed with the outer teeth of the first driven gear 5, and the second driven gear 6 is rotatably connected to the compactor body 1. A threaded rod 7 is fixedly installed on the outer side of the second driven gear 6. A first moving block 8 is threadedly connected to the outer side of the threaded rod 7. The device is equipped with a metal water pipe 9, with multiple nozzles 10 fixedly mounted at the bottom. A water source is connected to the rear of the first moving block 8. Simultaneously, the motor 3 drives the main gear 4, which in turn drives the first driven gear 5, the second driven gear 6, and the threaded rod 7 on their outer side to rotate. The threaded rod 7 drives the first moving block 8 to move. As the first moving block 8 moves, it sprays water in front of the compactor body 1, thereby wetting the ground and reducing dust raised during operation. This solves the problem of dust flying during ground compaction in existing technologies, while also preventing workers from inhaling dust, ensuring worker safety, and guaranteeing construction safety.

[0024] Specifically, a threaded rod 7 is fixedly installed on the outside of the first gear 5, and a second moving block 15 is threadedly connected to the outside of the other threaded rod 7. A metal water pipe 9 is installed on the outside of the second moving block 15. The first moving block 8 and the second moving block 15 alternately wet the bottom surface, which can ensure the dust suppression effect and at the same time avoid wasting water.

[0025] Furthermore, a water pipe 16 is fixedly installed on the rear side of the first moving block 8, and a water tank 17 is fixedly installed on the other side of the water pipe 16. Another water pipe 16 is fixedly installed on the rear side of the second moving block 15. The water pipe 16 is made of soft material and can move with the first moving block 8 and the second moving block 15, while providing them with a water source.

[0026] Furthermore, a water pipe 18 is fixedly installed on the rear side of the water tank 17, and a water distribution pipe 19 is fixedly installed at the bottom of the water pipe 18. Multiple water outlets 20 are fixedly installed on the bottom surface of the water distribution pipe 19, and the water outlets 20 penetrate the compactor body 1. Water is drawn into the interior of the water distribution pipe 19 by the water pipe 18 and then sprayed out from the water outlets 20 to perform dust suppression work again.

[0027] It is worth noting that a vibrating wheel 21 is rotatably mounted on the bottom surface of the compactor body 1, and the vibrating wheel 21 is located below the water outlet 20. The water sprayed from the water outlet 20 will spray onto the vibrating wheel 21, thereby wetting the surface of the vibrating wheel 21 and reducing dust in a small area near the vibrating wheel 21.

[0028] It is worth noting that the first moving block 8 has multiple locking blocks 13 inside, and the locking blocks 13 are engaged with the metal water pipe 9. The second moving block 15 has the same structure as the first moving block 8. When the metal water pipe 9 is not in use, it can be locked inside the locking blocks 13, thereby reducing the space occupied.

[0029] It is worth mentioning that a fixed shaft 11 is fixedly installed inside the first moving block 8, and a spring 14 is sleeved on the outside of the fixed shaft 11. A connecting shaft 12 is fixedly installed on the outside of the spring 14, and the fixed shaft 11 slides inside the connecting shaft 12. The connecting shaft 12 is fixedly connected to the locking block 13. When the metal water pipe 9 is working, the spring 14 pops out the locking block 13, thereby limiting the metal water pipe 9 and preventing it from swinging randomly due to the power of reciprocating motion.

[0030] Among them, the electric motor 3 is existing technology and will not be described in detail; at the same time, this utility model also includes a power supply, a controller, and a switch, etc., which are not the main technical points of this patent and will not be described in detail; the "front, back, left, and right" perspectives of this device are as follows: Figure 1 The direction shown in the diagram is the reference.

[0031] Working principle:

[0032] When using a vibratory compactor for backfilling large-section pipes, the vibratory roller 21 on the bottom of the compactor body 1 first compacts the pipe pit on the ground. During operation, the compactor body 1 inevitably generates a lot of dust. Then, the switch for the motor 3 on the top surface of the base plate 2 is turned on. The motor 3 drives the main gear 4 to rotate, which in turn drives the first driven gear 5 and the second driven gear 6. The second driven gear 6 and the first driven gear 5 drive the threaded rod 7 on its outer side to rotate. When the threaded rod 7 rotates, it drives the first moving block 8 and the second moving block 15 on its outer side to move. This movement causes the metal water pipe 9 to move. Water from inside the water tank 17 enters the metal water pipe 9 through the water inlet pipe 16 and is then sprayed out through the nozzle 10, thus wetting the ground and reducing dust. Water from the water tank 17 is then introduced into the metal water pipe 9 through the water inlet pipe 16. The water is then sprayed out through the nozzle 10, thus wetting the ground and reducing dust. Water pipe 18 on the other side of the water tank 17 leads the water from its interior to… The water enters the interior of the water inlet pipe 19 and is then sprayed onto the outside of the vibrating wheel 21 through the outlet 20, thus performing dust removal on one side. After use, the metal water pipe 9 is rotated and inserted into the clamping block 13 to store the metal water pipe 9 and reduce the space it occupies. When the metal water pipe 9 is in use, the spring 14 on the outside of the fixed shaft 11 will pop out the clamping block 13 through the connecting shaft 12, thus preventing the metal water pipe 9 from swinging randomly due to the back-and-forth force during operation. This utility model can reduce the dust raised during the compaction of the pipeline foundation pit through the internal water spray system, solving the problem of dust flying when compacting the ground in the prior art. It also avoids workers inhaling dust, ensuring the safety of workers and the safety of construction.
