Description

Technical Field

[0001] This utility model relates to the field of flattening device technology, and in particular to a road surface flattening device for municipal construction. Background Technology

[0002] In the field of municipal engineering construction, the quality of road construction is directly related to the stability and safety of urban transportation systems. A road surface compaction device for municipal construction, as a key piece of equipment to ensure the smoothness of the road surface, plays a role in compacting and leveling the paved road surface material by applying pressure, laying a solid foundation for subsequent road use. Whether it is building new roads or repairing and maintaining existing roads, this device undertakes an indispensable task, and its performance has a decisive impact on the final quality of the road surface.

[0003] Early road compaction devices mainly consisted of rigid rollers and simple power drive systems. This structure could play a certain role in compacting relatively flat roads. However, when encountering uneven surfaces, the rollers lacked self-adjustment capabilities, and one side was prone to lifting up during compaction, resulting in uneven road compaction and seriously affecting road quality. To solve this problem, existing devices have undergone many structural improvements, adopting rollers with elastic suspension systems. These systems attempt to adapt to road undulations through the deformation of elastic components. However, existing elastic suspension systems mostly rely on elastic elements such as springs. Under long-term high-intensity operation, these elastic elements will fatigue and deform. Once the performance of the elastic elements deteriorates, the rollers still cannot accurately conform to the road surface when facing complex uneven surfaces, and the lifting up of one side will still occur frequently, making it difficult to guarantee the compaction quality and smoothness of the road surface. Summary of the Invention

[0004] To overcome the above shortcomings, this utility model provides a road surface compaction device for municipal construction, which aims to improve the problem that under long-term high-intensity operation in the existing technology, the elastic element will fatigue and deform, and the compaction wheel still cannot accurately conform to the road surface.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a road surface compaction device for municipal construction, comprising an engineering vehicle, a hollow frame rotatably connected to the front side of the engineering vehicle, a connecting shaft fixedly connected to the middle of the inner wall of the hollow frame, a rotating block fixedly connected to the middle of the outer wall of the connecting shaft, a hollow limiting post rotatably connected to the outer wall of the rotating block, cavities being opened on both the front and rear sides of the right side of the hollow limiting post, a plurality of limiting posts slidably connected to the inner wall of the hollow limiting post, one end of the limiting post penetrating the hollow limiting post and fixedly connected to an arc-shaped plate, a plurality of buffer springs fixedly connected to the outer wall of the arc-shaped plate, the other end of the buffer springs fixedly connected to the outer wall of the hollow limiting post, a compaction cylinder slidably connected to the outer wall of the plurality of arc-shaped plates, an exhaust pipe connected to the rear side of the engineering vehicle, and a spraying mechanism provided at the top front end of the hollow frame for spraying water before compaction.

[0006] As a further description of the above technical solution: The spraying mechanism includes a water tank, the bottom of which is fixedly connected to the top front side of the hollow frame. A water pump is connected to the right side of the water tank, one end of which is connected to a hose. The other end of the hose passes through the hollow frame and is connected to a diversion pipe. Multiple nozzles are connected to the outer wall of the diversion pipe. A water tank cover is threadedly connected to the top left side of the water tank, and a filling port is connected to the top right side of the water tank.

[0007] As a further description of the above technical solution: A water level groove is provided on the front left side of the water storage tank, and a sealing sleeve is fixedly connected to the outer wall of the water level groove.

[0008] As a further description of the above technical solution: A column is fixedly connected to the top right end of the hollow frame, and a warning light is fixedly connected to the top of the column.

[0009] As a further description of the above technical solution: A limiting plate is fixedly connected to the top rear end of the hollow frame. A scraper is provided at the top of the limiting plate. Multiple bolts are provided on the inner wall of the scraper. The outer wall of the bolts engages with the inner wall of the limiting plate. The outer wall of the bolts is threadedly connected to the inner wall of the limiting plate.

[0010] As a further description of the above technical solution: The engineering vehicle is fixedly connected to rearview mirrors on both the left and right sides of its outer wall, and doors are rotatably connected to both the left and right sides of the engineering vehicle.

[0011] As a further description of the above technical solution: A ventilated plate is fixedly connected to the bottom of the outer wall of the car door, and a handle is fixedly connected to the middle of the outer wall of the car door.

[0012] As a further description of the above technical solution: A transparent window is provided at the top of the outer wall of the car door, and the transparent window is rounded.

[0013] This utility model has the following beneficial effects: 1. In this utility model, the buffer spring on the arc plate deforms during movement. When the compaction cylinder encounters a road surface protrusion, the arc plate is squeezed towards the limiting post, and the buffer spring is compressed, which plays a role in buffering and shock absorption, reducing the impact force. When the road surface is flat, the buffer spring pushes the arc plate and the compaction cylinder to move, maintaining close contact with the road surface. By using gravity and spring pressure, the road surface is compacted and flattened.

[0014] 2. In this utility model, a water storage tank provides a water source for watering operations. Before the device is started, water is quickly added through the filling interface. The water tank cover can be used to add chemicals. After starting, the water pump draws water from the water storage tank and delivers it to the distribution pipe through a hose. The distribution pipe evenly distributes the water to multiple nozzles, spraying the road surface in an atomized or columnar form to moisten and reduce hardness, making it easier for the compaction cylinder to compact the road surface and improving the compaction effect and quality.

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.

[0018] Reference Figure 1 , Figure 4 and Figure 5 This utility model provides an embodiment of a road surface leveling device for municipal construction, comprising an engineering vehicle 1, which serves as the carrier of the entire device. A hollow frame 3 is rotatably connected to the front of the engineering vehicle 1. A connecting shaft 4 is fixedly connected to the middle of the inner wall of the hollow frame 3. A rotating block 5 is fixedly connected to the middle of the outer wall of the connecting shaft 4. A hollow limiting post 6 is rotatably connected to the outer wall of the rotating block 5. Hollow cavities 12 are provided on the front and rear sides of the right side of the hollow limiting post 6. Multiple limiting posts 7 are slidably connected to the inner wall of the hollow limiting post 6. One end of the limiting post 7 passes through the hollow limiting post 6 and is fixedly connected to an arc-shaped plate 8. During the movement of the arc-shaped plate 8, its outer... Multiple buffer springs 9, which are fixedly connected to the wall, will continuously deform. Multiple buffer springs 9 are fixedly connected to the outer wall of the arc plate 8. When the roller 10 encounters a road protrusion, the arc plate 8 will be squeezed and moved towards the hollow limit post 6. The buffer springs 9 are compressed, which plays a role in buffering and shock absorption, reducing the impact force on the roller 10 and the entire device. The other end of the buffer spring 9 is fixedly connected to the outer wall of the hollow limit post 6. The roller 10 is slidably connected to the outer wall of multiple arc plates 8. The rear side of the engineering vehicle 1 is connected to the exhaust pipe 11. The top front end of the hollow frame 3 is provided with a spraying mechanism 2, which is used to spray water before compaction. Specifically, the engineering vehicle 1 serves as the carrier of the entire device. When the engineering vehicle 1 moves forward, it drives the hollow frame 3 connected to it to move synchronously. During the movement, the hollow frame 3 can flexibly rotate the engineering vehicle 1 according to the undulations of the road surface to maintain a suitable angle with the road surface and ensure the stability of the subsequent flattening operation. During the movement of the arc plate 8, the multiple buffer springs 9 fixedly connected to its outer wall will continuously deform. When the compaction cylinder 10 encounters a road surface protrusion, the arc plate 8 will be squeezed towards the hollow limit post 6, and the buffer springs 9 will be compressed, playing a role in buffering and shock absorption, reducing the impact force on the compaction cylinder 10 and the entire device. When the road surface is relatively flat, the buffer springs 9 will push the arc plate 8 and the compaction cylinder 10 outward, so that the compaction cylinder 10 always maintains close contact with the road surface. The compaction cylinder 10, which is slidably connected to the outer wall of the multiple arc plates 8, will perform compaction operations on the road surface by means of its own weight and the pressure applied by the buffer springs 9 during the movement of the device, flattening the road surface.

[0019] Reference Figure 1 , Figure 2 and Figure 3 The spraying mechanism 2 includes a water storage tank 201, which provides water for the entire spraying operation. The bottom of the water storage tank 201 is fixedly connected to the top front side of the hollow frame 3. A water pump 202 is connected to the right side of the water storage tank 201. One end of the water pump 202 is connected to a hose 203, and the other end of the hose 203 passes through the hollow frame 3 and is connected to a diversion pipe 204. Multiple nozzles 205 are connected to the outer wall of the diversion pipe 204. The water pump 202 draws water from the water storage tank 201 and transports it through the hose 203 connected to one end. After passing through the hose 203, the water enters the diversion pipe 204 that penetrates the hollow frame 3. The function of the diversion pipe 204 is to evenly distribute the water flow to multiple nozzles 205 connected to its outer wall, so that the water can be sprayed evenly on the road surface to be compacted in the form of atomization or columnar spray. The top left side of the water tank 201 is threaded with a water tank cover 206, which can be used to add other agents. The top right side of the water tank 201 is connected to a filling port 207, through which sufficient water can be quickly and conveniently injected into the water tank 201. Specifically, the water storage tank 201 provides water reserves for the entire watering operation. Before the device is started, sufficient water can be quickly and conveniently injected into the water storage tank 201 through the filling interface 207. At the same time, other agents can be added to the water tank cover 206. When the device is started and enters the road compaction preparation stage, the water pump 202 starts to work. The water pump 202 draws water out of the water storage tank 201 and transports it through the hose 203 connected to one end. After passing through the hose 203, the water enters the diversion pipe 204 that penetrates the hollow frame 3. The function of the diversion pipe 204 is to evenly distribute the water flow to the multiple nozzles 205 connected to its outer wall, so that the water can be sprayed evenly on the road surface to be compacted in the form of atomization or columnar spray, thereby wetting the road surface, reducing the hardness of the road surface material, and making the compaction cylinder 10 compact the road surface more during the compaction process, significantly improving the compaction effect and quality of the road surface.

[0020] Reference Figure 1 , Figure 2 and Figure 3A water level trough 13 is provided on the front left side of the water storage tank 201. The water level trough 13 provides a window for workers to directly observe the water level inside the water storage tank 201. A sealing sleeve 14 is fixedly connected to the outer wall of the water level trough 13. The sealing sleeve 14 can prevent dust, impurities and other foreign objects from entering the water storage tank 201 through the connection between the water level trough 13 and the outside. A column 15 is fixedly connected to the top right end of the hollow frame 3. The column 15 can raise the warning light 16 to a certain height, making it more conspicuous in the construction site. The top of the column 15 is fixed. A warning light 16 is connected, which can effectively attract the attention of people in the surrounding area; a limit plate 17 is fixedly connected to the top rear end of the hollow frame 3, and a scraper 18 is provided at the top of the limit plate 17. The scraper 18 can clean the debris that adheres to the top of the rolling cylinder 10 during the operation of the equipment. Multiple bolts 19 are provided on the inner wall of the scraper 18. The outer wall of the bolt 19 is engaged with the inner wall of the limit plate 17. The outer wall of the bolt 19 is threadedly connected to the inner wall of the limit plate 17. The bolts 19 make it easier to install and remove the scraper 18. Specifically, the water level tank 13 provides workers with a direct window to observe the water level in the water storage tank 201. This allows operators to monitor the water level in the tank in real time without opening it during construction, enabling timely replenishment. The sealing sleeve 14 prevents dust and impurities from entering the water storage tank 201 through the connection between the water level tank 13 and the outside, thus avoiding contamination and ensuring water quality. The pillar 15 allows the warning light 16 to be raised to a certain height, making it visible throughout the construction site. The device is highly visible, and the warning light 16 can effectively attract the attention of people in the surrounding area, alerting pedestrians, vehicles and other construction workers that there is a road compaction device in operation in the area, reminding them to pay attention to safety, avoid accidental collisions, and ensure the safety and order of the construction site. The scraper 18 can clean up the debris that adheres to the top of the compaction cylinder 10 during the operation of the equipment, ensuring the surface of the equipment is clean and preventing the accumulation of debris from affecting the normal operation of the equipment or interfering with subsequent construction. The bolt 19 makes it easy to install and remove the scraper 18.

[0021] Reference Figure 1 and Figure 2The engineering vehicle 1 has rearview mirrors 20 fixedly connected to both the left and right sides of its outer wall. The rearview mirrors 20 can clearly observe the road conditions behind and to the sides of the vehicle. The engineering vehicle 1 has doors 21 rotatably connected to both the left and right sides of its outer wall. The doors 21 provide convenient access for the driver and passengers to get on and off the vehicle. A ventilator 22 is fixedly connected to the bottom of the outer wall of the door 21. The ventilator 22 allows fresh air from the outside to enter the vehicle through small holes. A handle 23 is fixedly connected to the middle of the outer wall of the door 21. The handle 23 can be used to open the door 21 or close it when getting off the vehicle. A transparent window 24 is opened at the top of the outer wall of the door 21. The transparent window 24 is rounded and provides a certain range of vision for the people inside the vehicle. Specifically, the rearview mirror 20 provides a clear view of the road conditions behind and to the sides of the vehicle. The door 21 provides a convenient passage for the driver and passengers to get in and out of the vehicle. The vent 22 allows fresh air from the outside to enter the vehicle through small holes, while stale air inside the vehicle can be expelled outside, effectively improving the air quality inside the vehicle and providing a fresher breathing environment for the driver and passengers. This enhances driving and riding comfort and avoids discomfort such as stuffiness and dizziness caused by poor air circulation, thus helping to improve work efficiency. The handle 23 provides a point of leverage for both opening and closing the door 21 when getting out of the vehicle. The transparent window 24 provides a certain field of vision for the occupants, allowing them to observe some of the outside situation without opening the door 21, enhancing communication and perception with the outside world.

[0022] Working principle: First, as the supporting platform of the entire device, the engineering vehicle 1 moves forward, driving the connected hollow frame 3 to move synchronously. During the movement, the hollow frame 3 can rotate flexibly relative to the engineering vehicle 1 according to the undulation of the ground to maintain a suitable angle with the ground and ensure the stability of subsequent leveling operations. During the movement of the arc plate 8, the multiple buffer springs 9 fixedly connected to its outer wall will continuously deform. When the rolling cylinder 10 encounters a ground protrusion, the arc plate 8 will be squeezed towards the hollow limit post 6, and the buffer springs 9 will be compressed, playing a role in buffering and shock absorption, reducing the impact force on the rolling cylinder 10 and the entire device. When the ground is relatively flat, the buffer springs 9 will push the arc plate 8 and the rolling cylinder 10 outward, so that the rolling cylinder 10 always maintains close contact with the ground. The rolling cylinder 10, which is slidably connected to the outer wall of the multiple arc plates 8, rolls the ground with its own weight and the pressure applied by the buffer springs 9 during the movement of the device, flattening the ground. Furthermore, through the spraying mechanism 2, the water storage tank 201 serves as the water source reserve for the entire watering operation. Before the device is started, an appropriate amount of water can be quickly and conveniently injected into the water storage tank 201 through the filling interface 207. At the same time, the water tank cover 206 can be used to add other agents. When the device is started and enters the preparation stage of the road compaction operation, the water pump 202 starts to operate, drawing water from the water storage tank 201 and transporting it through the hose 203 connected to one end. After passing through the hose 203, the water enters the diversion pipe 204 that penetrates the hollow frame 3. The function of the diversion pipe 204 is to evenly distribute the water flow to the multiple nozzles 205 connected to its outer wall, so that the water can be evenly sprayed on the road surface to be compacted in the form of atomization or columnar spray, thereby wetting the road surface, reducing the hardness of the road surface material, and making the compaction cylinder 10 compact the road surface more during the compaction process, significantly improving the compaction effect and quality of the road surface.
