Description

Technical Field

[0001] The invention relates to the technical field of building construction, in particular to a ground compacting device for building construction and a working method thereof. Background Art

[0002] In construction, compaction technology is widely used in the leveling and reinforcement of roads, foundations, yards and other sites. Through the vibration or impact of the compaction device, the density of soil and base materials can be effectively improved, providing a solid foundation for subsequent construction. Traditional compaction devices usually use a compaction plate in contact with the ground to compact the base material through external force. However, this traditional compaction method has some limitations, especially during the compaction process, the bottom of the compaction plate is prone to adhere to soil, gravel and other materials, resulting in uneven contact between the compaction plate and the ground, thereby affecting the stability and uniformity of the compaction effect. The accumulation or adhesion of materials on the base material not only reduces the construction efficiency, but also leads to the degradation of the compaction effect, making it difficult to ensure the construction quality.

[0003] In terms of dust reduction, a large amount of smoke and dust will be generated during the construction process due to the compaction effect, which not only affects the health of workers but also causes environmental pollution. Most of the existing compaction equipment is not equipped with an effective dust reduction system, resulting in the spread of smoke and dust, affecting the air quality at the construction site. Although some equipment has begun to use a water spray dust reduction system, there are still problems such as inaccurate water spray control, excessive or insufficient water spraying, making it difficult to achieve uniform coverage, resulting in unsatisfactory dust reduction effects, and also easily causing a waste of water resources.

[0004] Therefore, those skilled in the art have proposed a ground compaction device for construction and a working method thereof to solve the above-mentioned problems. Summary of the invention

[0010] Preferably, one-way valves are installed inside the air inlet pipe and the connecting pipe, and the conduction directions of the two one-way valves are opposite.

[0011] Preferably, the output end of motor 2 is fixedly connected to bevel gear 2, the outer side of bevel gear 2 is meshingly connected to bevel gear 1, the outer side of bevel gear 1 is fixedly connected to synchronous wheel 2, the outer side of synchronous wheel 2 is connected to synchronous wheel 1 via a belt, a rake roller is rotatably installed on one side of the bottom end of the vehicle body, and synchronous wheel 2 is fixedly connected to one end of the rake roller.

[0012] Preferably, the longitudinal section of the piston 2 is arranged to be square, and the outer surface of the piston 2 is slidably connected to the inner wall of the quantitative box.

[0013] Preferably, the bottom end of the movable rod passes through the top of the support frame and is fixedly connected to the top of the tamping plate, and the four corners of the bottom of the vehicle body are fixedly connected with walking wheels.

[0014] A working method of a ground compacting device for building construction comprises the following steps:

[0015] Step 1: Move the device to the working area to be compacted. At this time, start the motor 2 to drive the rotating disk to rotate, so as to drive the fixed block to rotate along the outer surface of the rotating disk. At this time, the fixed block moves along the movable groove inside the movable frame, and the movable frame moves up and down along the inner wall of the limit frame. The movement of the movable frame drives the connecting rod and the compacting plate to move synchronously, so as to compact the ground;

[0016] Step 2: As the output end of the second motor drives, the second bevel gear is driven to rotate, and then the meshing bevel gear is driven to rotate, the rotation of the first bevel gear drives the second synchronous wheel to rotate, the second synchronous wheel drives the first synchronous wheel to rotate through the belt transmission, and the first synchronous wheel drives the harrow roller to rotate to loosen the soil on the ground;

[0017] Step 3: When the compacting plate reciprocates up and down, the movable rod is driven to move up and down, thereby driving the piston to move up and down along the inner wall of the fixed cylinder, so that the air inside the fixed cylinder enters the air blowing pipe through the connecting pipe, and the base material at the bottom of the compacting plate is removed by high-pressure airflow;

[0018] Step 4. During the soil compaction process, smoke and dust will be generated. At this time, the dust-reducing water inside the water tank is transported to the second transport pipe through the first transport pipe by starting the pump body, and enters the cavity inside the quantitative box through the second transport pipe. After the cavity is filled, the driving screw is driven to rotate by starting motor 1. At this time, the threaded frame moves along the outer surface of the driving screw until the dust-reducing water is sprayed out through the spray pipe for dust reduction treatment. Subsequently, the initial position of piston 2 only needs to remain unchanged to spray the dust-reducing water quantitatively.

[0019] The present invention provides a ground compaction device for construction and a working method thereof, which has the following beneficial effects:

[0020] 1. The present invention can automatically clean the base material at the bottom of the tamping plate during the tamping process, thereby maintaining good contact between the tamping plate and the base surface, avoiding the accumulation or adhesion of materials such as soil and gravel that affect the tamping effect, thereby ensuring the uniformity and stability of the tamping operation and improving the construction quality. Secondly, the device does not require manual intervention for cleaning, effectively reducing the workload of manual operations, saving time and labor costs, significantly improving work efficiency, and shortening the construction period.

[0021] 2. The present invention uses a quantitative water spraying method to treat the smoke and dust generated during the compaction process, ensuring that the water is evenly distributed during the dust reduction process, avoiding waste caused by too much or too little water spraying or failing to effectively suppress the smoke and dust, thereby saving water while ensuring the dust reduction effect and improving the efficiency of resource utilization. Secondly, by using quantitative water spraying to treat the smoke and dust in real time, the suspended particulate matter in the air is effectively reduced, the air quality at the construction site is significantly improved, the harm to the health of workers during the construction process is reduced, the occurrence of respiratory diseases is reduced, and the safety and comfort of the workers' working environment are improved.

[0022] 3. During the operation of the compacting plate, the present invention can drive the rake roller to rotate, and the soil, sand, gravel and other materials on the ground can be gathered and loosened by the rotating rake roller, thereby helping to eliminate unevenness, debris and particles on the ground, thereby improving the effect of the compaction operation.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Please see attached Figure 1 - Attachment Figure 8 The embodiment of the present invention provides a ground compacting device for construction, comprising a vehicle body 1, a support frame 401 is fixedly connected to one side of the top of the vehicle body 1, two fixed cylinders 402 are fixedly connected to the top of the support frame 401, a cavity is opened inside the fixed cylinder 402, a piston 406 is slidably connected inside the cavity, a movable rod 405 is fixedly connected to the outer side of the piston 406, an air intake pipe 407 is connected to the outer side of the fixed cylinder 402, a connecting pipe 404 is also connected to the outer side of the fixed cylinder 402, and an air blowing pipe 403 is fixedly connected to one end of the connecting pipe 404, a mounting frame 2 is fixedly connected to one side of the top of the vehicle body 1, two limiting frames 302 are fixedly connected to the outer side of the mounting frame 2, a movable frame 303 is slidably connected to the inner wall of the limiting frame 302, a connecting rod 305 is fixedly connected to the outer side of the movable frame 303, a tamping plate 306 is fixedly connected to the bottom end of the connecting rod 305, and a rotating disk 301 is installed on the outer side of the mounting frame 2. One-way valves are installed inside the air intake pipe 407 and the connecting pipe 404, and the two one-way valves are in opposite directions. The bottom end of the movable rod 405 passes through the top of the support frame 401 and is fixedly connected to the top of the tamping plate 306. The four corners of the bottom of the vehicle body 1 are fixedly connected with running wheels.

[0034] Specifically, the vehicle body 1, as the main part of the entire device, carries all other components, ensuring the stability and mobility of the device. The fixed cylinder 402 is fixedly connected to the support frame 401, and a cavity is provided inside it, and a piston 406 is slidably connected in the cavity. Piston 406 is one of the key components in the device, and drives the gas flow by sliding up and down. The outer side of piston 406 is fixedly connected with a movable rod 405, and the movable rod 405 moves up and down during the tamping operation to provide the necessary driving force for the tamping plate 306. The up and down movement of piston 406 is to control the flow of gas, thereby achieving the cleaning of the base material at the bottom of the tamping plate 306. The air inlet pipe 407 is connected to the external air source, and provides air to flow into the cavity of the fixed cylinder 402, thereby promoting the movement of piston 406. The connecting pipe 404 guides the air inside the fixed cylinder 402 to the blowing pipe 403. In order to avoid the backflow of air, one-way valves are installed inside the air intake pipe 407 and the connecting pipe 404, and the conduction directions of the two one-way valves are opposite, ensuring that the air can only flow in the correct direction, and there will be no reversal of airflow, thereby ensuring the stability of the device and the efficient use of airflow. The rotating disk 301 is installed on the outside of the mounting frame 2, and its function is to provide the device with a mobile function. The rotating disk 301 helps the compaction device to move on the construction site by rotating, thereby improving work efficiency. Walking wheels are provided at the four corners of the bottom of the vehicle body 1 to ensure that the device can move smoothly and flexibly in different construction environments. The design of the walking wheels allows the device to not only move smoothly on a flat ground, but also adapt to the requirements of some complex terrains.

[0035] When the compacting plate 306 starts to reciprocate up and down, the movable rod 405 drives the piston 1 406 to slide up and down inside the fixed cylinder 402. As the piston 1 406 moves, the air inside the fixed cylinder 402 enters the air blowing pipe 403 through the connecting pipe 404 and is ejected through the air blowing pipe 403. The high-pressure airflow through the air blowing pipe 403 can effectively clean the soil, gravel and other base materials accumulated at the bottom of the compacting plate 306, avoid the accumulation or adhesion of these materials, maintain good contact between the compacting plate 306 and the ground, and thus ensure the uniformity and stability of the compaction operation.

[0036] A second motor 602 is installed on the outside of the mounting frame 2, and the output end of the second motor 602 is fixedly connected to the rotating disk 301, and a fixed block 304 is fixedly connected to the outer eccentric part of the rotating disk 301. A movable groove is arranged inside the movable frame 303, and the fixed block 304 is arranged inside the movable groove.

[0037] Specifically, the movable groove ensures that the fixed block 304 can drive the movable frame 303 to move up and down during the movement.

[0038] A water tank 501 is fixedly connected to one side of the top of the vehicle body 1, a quantitative box 502 is fixedly connected to the top of the water tank 501, a motor 1 503 is installed on the outside of the quantitative box 502, a driving screw 504 is fixedly connected to the output end of the motor 1 503, a threaded rack 505 is threadedly connected to the outside of the driving screw 504, a piston 2 506 is fixedly connected to the outside of the threaded rack 505, and a liquid spraying pipe 507 is connected to one side of the bottom of the quantitative box 502. A pump body 701 is installed on the top of the water tank 501, a second transport pipe 703 is fixedly connected to the output end of the pump body 701, a first transport pipe 702 is fixedly connected to the input end of the pump body 701, one end of the first transport pipe 702 is connected to the outside of the water tank 501, one end of the second transport pipe 703 is connected to one side of the top of the quantitative box 502, and a control valve is installed on the outer surface of the second transport pipe 703. The longitudinal section of the second piston 506 is set to be square, and the outer surface of the second piston 506 is slidably connected to the inner wall of the quantitative box 502.

[0039] Specifically, the main function of the water tank 501 is to store dust suppression water. During the soil compaction process, the water in the water tank 501 is transported to the downstream dust treatment system through the driving system of the equipment. The quantitative box 502 is fixed on the top of the water tank 501, and a motor 503 is installed on the outside. The function of the motor 503 is to provide mechanical power to drive the screw 504. The motor 503 is connected to the drive screw 504 through its output end. The rotation of the drive screw 504 is one of the core actions of the entire dust suppression system, driving the threaded frame 505 to perform precise linear movement in the quantitative box 502. The threaded frame 505 is fixedly connected to the piston 2 506, so the movement of the threaded frame 505 directly causes the piston 2 506 to slide along the inner wall of the quantitative box 502. In this way, the movement of the piston 2 506 realizes the control of the quantitative water volume, ensuring that the dust suppression water of the system can be sprayed at precise timing and flow rate. The main function of the second piston 506 is to control the amount of liquid in the quantitative box 502. It adopts a square longitudinal section design so that it can slide well with the inner wall in the quantitative box 502 to avoid liquid leakage. As the threaded frame 505 moves, the second piston 506 moves forward or backward, pushing the water flow in the quantitative box 502 to spray through the liquid spraying pipe 507. Therefore, the second piston 506 can ensure that the water in the quantitative box 502 can be evenly and accurately sprayed through the liquid spraying pipe 507 after being filled, which is used for soil dust reduction.

[0040] The pump body 701 is installed on the top of the water tank 501 and is responsible for transporting the dust suppression water in the water tank 501 to the second transport pipe 703 through the first transport pipe 702. The output end of the pump body 701 is connected to the top of the quantitative tank 502 through the second transport pipe 703 to form a closed water circulation system. After the pump body 701 is started, it drives the water flow to be transported to the quantitative tank 502 through the pipeline to ensure the supply of water. In addition, the outer surfaces of the second transport pipe 703 and the spray pipe 507 are both installed with control valves, which can adjust the water flow according to actual needs to ensure that the amount of water in the quantitative tank 502 does not exceed the set value for accurate spraying.

[0041] The output end of motor 2 602 is fixedly connected to bevel gear 2 604, the outer side of bevel gear 2 604 is meshingly connected to bevel gear 1 603, the outer side of bevel gear 1 603 is fixedly connected to synchronous wheel 2 606, the outer side of synchronous wheel 2 606 is connected to synchronous wheel 1 605 via a belt, and a rake roller 601 is rotatably installed on one side of the bottom end of the vehicle body 1, and synchronous wheel 2 606 is fixedly connected to one end of the rake roller 601.

[0042] Specifically, the output end drive of motor 2 602 drives bevel gear 2 604 to rotate, and then drives the meshing bevel gear 1 603 to rotate. The rotation of bevel gear 1 603 drives synchronous wheel 2 606 to rotate. Synchronous wheel 2 606 drives synchronous wheel 1 605 to rotate through belt transmission. The synchronous wheel 1 605 drives the harrowing roller 601 to rotate to loosen the soil on the ground. The rotating harrowing roller 601 gathers and loosens the soil, sand, gravel and other materials on the ground, helping to eliminate unevenness, debris and particles on the ground, thereby improving the effect of the compaction operation.

[0043] A working method of a ground compacting device for building construction comprises the following steps:

[0044] Step 1, move the device to the working area to be compacted, and at this time, start the motor 2 602 to drive the rotating disk 301 to rotate, so as to drive the fixed block 304 to rotate along the outer surface of the rotating disk 301, and at this time, the fixed block 304 moves along the movable groove inside the movable frame 303, and the movable frame 303 moves up and down along the inner wall of the limit frame 302. The movement of the movable frame 303 drives the connecting rod 305 and the compacting plate 306 to move synchronously, so as to compact the ground;

[0045] Step 2: As the output end of the second motor 602 drives, the second bevel gear 604 is driven to rotate, and then the meshed bevel gear 1 603 is driven to rotate, and the rotation of the bevel gear 1 603 drives the synchronous wheel 2 606 to rotate, and the synchronous wheel 2 606 drives the synchronous wheel 1 605 to rotate through the belt transmission, and the synchronous wheel 1 605 drives the rake roller 601 to rotate to loosen the soil on the ground;

[0046] Step 3: When the compacting plate 306 reciprocates up and down, the movable rod 405 is driven to move up and down, thereby driving the piston 1 406 to move up and down along the inner wall of the fixed cylinder 402, so that the air inside the fixed cylinder 402 enters the blowing pipe 403 through the connecting pipe 404, and the base material at the bottom of the compacting plate 306 is removed by high-pressure airflow;

[0047] Step 4. During the soil compaction process, smoke and dust will be generated. At this time, the dust-reducing water inside the water tank 501 is transported to the second transport pipe 703 through the first transport pipe 702 by starting the pump body 701, and enters the cavity inside the quantitative box 502 through the second transport pipe 703. After the cavity is filled, the driving screw 504 is driven to rotate by starting the motor 1 503. At this time, the threaded frame 505 moves along the outer surface of the driving screw 504 until the dust-reducing water is sprayed out through the spray pipe 507 for dust reduction treatment. Subsequently, the initial position of the piston 2 506 only needs to remain unchanged to spray the dust-reducing water quantitatively.

[0048] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.

At this time, the dust-reducing water in the water tank (501) is transported to the second transport pipe (703) through the first transport pipe (702) by starting the pump body (701), and enters the cavity inside the quantitative box (502) through the second transport pipe (703). After the cavity is filled, the driving screw (504) is driven to rotate by starting the motor 1 (503). At this time, the threaded frame (505) moves along the outer surface of the driving screw (504) until the dust-reducing water is sprayed out through the spray pipe (507) to carry out dust reduction treatment. Subsequently, the initial position of the piston 2 (506) only needs to remain unchanged to spray the dust-reducing water quantitatively.
