Description

Technical Field

[0001] This utility model relates to the field of road construction equipment technology, and in particular to a compaction molding device for multi-slope beam surfaces. Background Technology

[0002] In road and bridge construction, the quality and effect of beam surface compaction have a significant impact on the overall performance of the bridge. Simple compaction only ensures material density, but the quality of the surface finish affects the flatness and smoothness of the beam surface. High-quality finishing reduces surface defects and improves aesthetics; a good finish also enhances the adhesion between the beam surface and subsequent pavement layers, ensuring the integrity of the bridge structure. For example, on bridges with heavy vehicle traffic, poor compaction quality and finish can lead to cracks and potholes, affecting driving comfort and safety, and shortening the bridge's service life.

[0003] Traditional beam surface compaction molding devices have several shortcomings in practical applications. Most traditional devices can only achieve a single slope for beam surface finishing, making it difficult to meet the requirements of complex projects where multiple slopes are needed for the same interface. Their structural design lacks flexibility, failing to accurately create multiple slopes in different areas of the same beam surface to address the differences in drainage and stress in different parts of the bridge. This leads to poor drainage, increases the risk of water accumulation on the beam, and affects the beam's service life. Furthermore, traditional devices have limited precision in slope adjustment, failing to meet the standards of high-precision slope control, thus restricting their application in complex beam surface projects. Utility Model Content

[0025] Example 1:

[0026] like Figures 1 to 3 As shown in this embodiment, a compaction molding device for multi-slope beam surfaces includes a frame 10 and side rods 11 fixedly connected to both sides of the frame 10. Rollers 12 are rotatably connected to the ends of the side rods 11 that contact the ground. A connecting frame 13 is also fixed on the frame 10. The device also includes a first lifting roller 20 and a second lifting roller 21 rotatably connected to both sides of the first lifting roller 20. Both the first lifting roller 20 and the second lifting roller 21 are rotatably connected to the connecting frame 13. The frame 10 is provided with a wetting mechanism for spraying water onto the beam surface and a vibration mechanism for causing the first lifting roller 20 and the second lifting roller 21 to vibrate. The vibration mechanism is used to assist in compacting the beam surface.

[0027] This solution aims to address the problems of traditional beam surface compaction molding devices, such as difficulty in accurately controlling slope, poor compaction effect, and poor adaptability. In the device, the connecting frame 13, made of robust steel, is securely fixed to the frame 10, providing reliable support for the first and second slurry rollers 20 and 21. During operation, the frame 10 is driven forward by rollers 12. The motor 14 of the wetting mechanism drives blades 161 to spray water from the water tank 15 through the nozzles of the sprayer 17, wetting the beam surface. The vibration mechanism, through the motor 14's rotating shaft 16, drives the eccentric rod 212 and connecting rod 211, causing the second slurry roller 21 to vibrate and assist compaction. Precise slope control ensures smooth drainage of the beam surface, improving the compaction quality and stability of the beam surface. As an alternative, the rollers 12 can be replaced with tracks to adapt to different terrains and improve the device's adaptability.

[0028] In this embodiment, along the direction from the center of the beam surface to the curb, the end of the second slurry roller 21 near the curb has a slope, and the slope inclination ratio ranges from 1.5% to 4.5%.

[0029] The second lifting roller 21 is made of high-strength aluminum alloy. At its end near the curb, it is precisely machined to create a slope of 1.5%-4.5%. In practical applications, as the roller 12 drives the frame 10 forward along the beam, this slope of the second lifting roller 21 effectively compacts the beam surface and creates an inclination that meets drainage requirements, allowing rainwater to drain smoothly towards the curb. An alternative solution is to install an adjustable slope component at the end of the second lifting roller 21, allowing for real-time adjustment of the slope value according to actual needs.

[0030] In the construction of multi-slope beam surfaces, this device has significant advantages in slope control. The second slurry roller 21 is precisely machined at its end near the curb to form a slope of 1.5%-4.5%. When the roller 12 drives the frame 10 forward, it can effectively compact the beam surface and precisely shape the inclination to meet drainage requirements, allowing rainwater to flow smoothly to the curb. The first slurry roller 20 is machined at its end near the second slurry roller 21 with a slope of 0.75%-2%. This slope, combined with that of the second slurry roller 21, makes the compaction transition of the beam surface from the center to the curb smoother, ensuring precise control and connection of the beam surface slope in all aspects.

[0031] In this embodiment, along the direction from the center of the beam surface to the curb, the end of the first slurry roller 20 near the second slurry roller 21 has a slope, and the slope inclination ratio ranges from 0.75% to 2%.

[0032] The first lifting roller 20 is made of alloy steel, and a slope of 0.75%-2% is machined at the end near the second lifting roller 21. The working principle is that when the device is in operation, the first lifting roller 20 rotates under the support of the connecting frame 13. The slope at this end, combined with the slope of the second lifting roller 21, makes the compaction transition of the beam surface from the center to the curb smoother, improving the overall compaction and finishing quality of the beam surface.

[0033] This solution offers significant advantages in achieving multiple slope finishes on the same surface. Firstly, it overcomes the limitations of traditional equipment, greatly improving construction efficiency. Traditional operations require frequent equipment changes or complex manual adjustments when multiple slopes are needed, which is time-consuming and labor-intensive. This device, by controlling the working states of the first and second slurry rollers, can quickly and accurately create different slopes on the same beam surface, significantly shortening the construction cycle. Secondly, from an engineering quality perspective, this function ensures optimal drainage performance of the beam surface. Based on the drainage requirements of different areas, such as setting a larger slope at the edges of the beam surface prone to water accumulation and a relatively smaller slope at the center, rainwater can be quickly and smoothly drained, effectively reducing the erosion of the beam structure by accumulated water, extending the bridge's service life, and providing a solid guarantee for the long-term stable operation of the bridge.

[0034] This device achieves a surface finishing accuracy within 1mm, ensuring the effectiveness of surface grinding before PPU waterproofing application. This high-precision finishing results in extremely high beam surface flatness, effectively preventing uneven application of the PPU waterproofing material due to uneven substrate surfaces. The uniformly applied waterproofing material forms a seamless, bubble-free waterproof layer, significantly improving waterproofing performance and effectively preventing rainwater and other external moisture from eroding the beam structure, extending the bridge's service life. Furthermore, the precise finishing accuracy reduces subsequent waterproofing repair steps, lowering construction costs and time, and improving overall construction efficiency.

[0035] In this embodiment, an adjusting wheel 111 is rotatably connected to the side rod 11.

[0036] The adjusting wheel 111 is rotatably connected to the side rod 11 via a high-precision bearing. During construction, when encountering uneven ground, the height of the adjusting wheel 111 can be adjusted to change the horizontal state of the frame 10, ensuring the smooth operation of the roller 12 and good contact between the slurry roller and the beam surface, thus guaranteeing smooth compaction. An alternative solution is to use retractable hydraulic support feet instead of the adjusting wheel 111, achieving more precise height adjustment and support.

[0037] In this embodiment, the humidification mechanism includes a water tank 15 fixed on the frame 10. A motor 14 and a sprayer 17 are fixedly connected to the water tank 15. The sprayer 17 has a cavity inside, which communicates with the inside of the water tank 15. An opening is provided on the sprayer 17 to communicate with the cavity. The rotating shaft 16 of the motor 14 passes through the cavity. A blade 161 is fixed to a section of the rotating shaft 16 inside the cavity. When the rotating shaft 16 drives the blade 161 to rotate, water can be sprayed out from the opening.

[0038] The water tank 15 is made of corrosion-resistant plastic and is fixed to the frame 10. The motor 14 is tightly connected to the water tank 15, and its rotating shaft 16 passes through the internal cavity of the sprayer 17. The sprayer 17 is made of stainless steel, and its internal cavity is connected to the water tank 15 through a sealed pipe. Multiple openings are evenly distributed on its surface. When the motor 14 operates, the rotating shaft 16 drives the blades 161 to rotate, generating pressure that sprays water from the water tank 15 at high speed through the openings, evenly wetting the beam surface. An alternative solution is to replace the blade 161 type water pump with a plunger pump to improve the spray pressure and stability.

[0039] In this embodiment, the vibration mechanism includes a connecting rod 211 fixedly connected to the second lifting roller 21. One end of the connecting rod 211 is fixed to the second lifting roller 21, and the other end of the connecting rod 211 is fixedly connected to the end of an eccentric rod 212. The axis of the eccentric rod 212 does not coincide with the axis of the connecting rod 211, and the other end of the eccentric rod 212 is fixedly connected to the outer end of the rotating shaft 16. When the motor 14 drives the rotating shaft 16 to rotate, the second lifting roller 21 can vibrate through the eccentric rod 212 and the connecting rod 211.

[0040] Both connecting rod 211 and eccentric rod 212 are made of high-carbon steel. One end of connecting rod 211 is welded and fixed to the second slurry roller 21, and the other end is firmly connected to the end of eccentric rod 212. The other end of eccentric rod 212 is connected to the outer end of the motor shaft 16 via a key. When the motor 14 is working, the shaft 16 drives the eccentric rod 212 to rotate. Since the axis of eccentric rod 212 does not coincide with the axis of connecting rod 211, the second slurry roller 21 vibrates through connecting rod 211, thereby improving the compaction density of the beam surface.

[0041] When the device is in operation, the roller 12, driven by the motor 14, propels the frame 10 forward along the multi-slope beam surface. During this process, the motor 14 of the wetting mechanism drives the blades 161 to rotate, spraying water from the water tank 15 through the opening of the sprayer 17 to evenly wet the beam surface. Simultaneously, the motor 14, which drives the lifting rollers, rotates, causing the first and second lifting rollers 21 to rotate and compact the beam surface, with the slope at the end of the second lifting roller 21 creating the beam surface inclination. In addition, the motor 14, through the structure of the eccentric rod 212 and connecting rod 211, causes the second lifting roller 21 to vibrate, assisting in compaction. When encountering uneven ground, the height of the adjusting wheel 111 on the side rod 11 can be adjusted to ensure stable operation of the device and good contact between the lifting rollers and the beam surface, completing the beam surface compaction and shaping work.

[0042] Example 2:

[0043] In this embodiment, the sprayer 17 has multiple openings. During operation, the motor 14 drives the blades 161 to spray water from the water tank 15 through the multiple openings, making the beam surface more evenly wetted and improving the compaction effect. An alternative is to use openings of different shapes, such as long strips or fan shapes, to adapt to different beam widths and wetting requirements.

[0044] In this embodiment, the connecting rod 211 and the eccentric rod 212 are the same size. Both the connecting rod 211 and the eccentric rod 212 undergo precise machining and heat treatment to ensure dimensional accuracy and strength. During manufacturing, the identical dimensions of both are strictly controlled to ensure smoother vibration transmission. During operation, the motor 14's shaft 16 drives the eccentric rod 212, which in turn causes the second lifting roller 21 to vibrate stably through the connecting rod 211. An alternative approach is to optimize the dimensional ratio of the connecting rod 211 and the eccentric rod 212 through computer simulation to find better vibration transmission parameters.

[0045] When applied to multi-slope beam compaction, this device offers several significant advantages. First, the precisely controlled slopes of the first and second lifting rollers 21 ensure the beam surface achieves a drainage-compliant inclination, effectively guiding rainwater down and preventing water accumulation that could damage the beam surface. Second, the wetting mechanism evenly wets the beam surface before compaction, laying the foundation for good compaction results; the vibration mechanism further enhances the compaction effect, improving the density and stability of the beam surface. Furthermore, the adjustable wheels 111 allow the device to adapt to complex terrain, improving construction efficiency and quality.
