Description

Technical Field

[0001] The utility model relates to the technical field of pavement construction, and more specifically, to an intelligent pavement compaction device. Background Art

[0002] The pavement compaction device is a key equipment in road construction. Its main function is to compact the laid pavement materials to improve the density and flatness of the pavement, ensuring the service life of the road and driving safety. The importance of compaction operations is reflected in aspects such as improving material density, enhancing pavement bearing capacity, extending service life, and ensuring pavement flatness. With the progress of technology, pavement compaction devices have gradually developed into various types such as static rollers, vibratory rollers, and pneumatic-tyred rollers to meet the compaction requirements of different pavement materials. Modern compaction equipment has started to adopt intelligent control systems to automatically adjust compaction parameters, improving compaction efficiency and quality. At the same time, environmental protection, energy conservation, and multi-functional integration have also become the development trends of compaction device technology. However, technical challenges such as compaction uniformity, adaptability, and operation safety still need to be continuously overcome. Generally speaking, the technical development of pavement compaction devices is an important manifestation of the progress of road engineering technology and plays an important role in improving the quality and efficiency of road engineering.

[0003] Most of the existing pavement compaction devices use the method of static rolling, compacting by the gravity of the machine itself. The compaction efficiency of this method is relatively low because it has no vibration function and cannot promote the displacement between material particles through vibration, thus requiring more time and passes to complete the compaction work. Secondly, the penetration ability into the material during compaction is weak, and for some materials that are difficult to compact, the ideal compaction effect may not be achieved. In addition, the adaptability of the static rolling method is poor. For different types of pavement materials and different construction conditions, different compaction strategies may be required, but the adjustment range of the static rolling method is limited. Moreover, since the machines used in the static rolling method are usually large in volume and heavy in weight, there are certain limitations in operation flexibility, especially in construction sites with narrow spaces or complex terrains. Finally, the initial investment and operating costs of the machines used in the static rolling method are relatively high, and the maintenance is relatively complex.

[0004] A Chinese utility model patent with the publication number CN218756866 discloses an impact vibration wheel for improving road surface compaction degree, which includes two rolling wheels. A traction device is connected between the two rolling wheels, and the traction device is connected to a tractor. A placement bin is fixedly connected inside the rolling wheel. A counterweight block matching the placement bin is placed in the placement bin, and the counterweight block is movably connected inside the placement bin. A fixed block is fixedly connected to the bottom of the placement bin, and the fixed block is fixedly connected to the protruding part of the rolling wheel. A placement opening is formed on one side of the rolling wheel. The placement opening is matched with the placement bin and communicates with the placement bin. A cover plate matching the placement opening is movably connected inside the placement opening. A counterweight block is added inside the rolling wheel, and the counterweight block can move up and down inside the placement bin.

[0005] Although when the above device rotates to a high place and then falls, the counterweight block makes a free fall motion and hits the bottom of the placement bin, and the force is transmitted to the protruding part of the rolling wheel through the fixed block, achieving a more powerful effect of compacting the road surface, but vehicles need to be arranged for transportation before and after construction, and it cannot be directly towed behind the towing vehicle to the next construction site. Moreover, the vibration generated during construction will be directly transmitted to the tractor in front, affecting the driver's driving. Utility Model Content

[0006] The present utility model aims at the defects of the prior art and proposes a new type of road surface compaction device. This device can effectively reduce the impact of vibration on the driver during the construction process. At the same time, after the construction task is completed, it can be conveniently towed behind the towing vehicle and quickly transferred to the next construction site, thus avoiding frequent disassembly, installation, and unnecessary transportation burdens.

[0007] The technical solution measures of the present utility model are as follows:

[0008] An intelligent road surface compaction device includes a traction assembly. A rolling wheel is arranged behind the traction assembly. The traction assembly includes a traction frame. A limit sliding groove is formed on the traction frame. When the rolling wheel works, it slides up and down in the limit sliding groove to compact the road surface by using the high-position potential energy. A lifting assembly is also arranged on the traction frame. An auxiliary wheel is arranged below the lifting assembly on the traction frame. The lifting assembly lifts the rolling wheel off the ground, and when the road surface compaction device is towed, it does not affect the normal driving of the tractor in cooperation with the auxiliary wheel. A connection assembly is also arranged at the front end of the traction frame, and the connection assembly can reduce the vibration generated by the rolling wheel during work on the tractor.

[0009] As a preference, the lifting assembly includes a hydraulic cylinder barrel arranged on the traction frame. A hydraulic rod is arranged inside the hydraulic cylinder barrel. The end of the hydraulic rod is provided with a wheel shaft sleeve connected to the wheel shaft of the rolling wheel.

[0010] Preferably, the connecting assembly comprises fixed wing plates arranged on the traction frame, a sliding shaft is arranged between the fixed wing plates, a sleeve is slidably arranged on the sliding shaft, and a spring damping plate is arranged on the sleeve.

[0011] As a preference, a plurality of telescopic rods are arranged on the spring shock-absorbing plate, the other ends of the telescopic rods are connected to the fixed wing plates, and shock-absorbing springs are also arranged on the outer sides of the telescopic rods.

[0012] As a preferred embodiment, a tractor joint is also provided at the end of the spring damping plate.

[0013] As a preferred embodiment, the traction frame is an I-shaped steel beam structure.

[0014] The beneficial effects of the utility model are:

[0015] 1. Significantly improved construction efficiency and transportation convenience: The utility model uses a carefully designed lifting assembly and auxiliary wheels to achieve rapid conversion of the road compaction device into towing mode after the construction task is completed. This innovation avoids the tedious disassembly and reinstallation steps that traditional equipment must undergo during the transfer process, greatly reducing the idle time of the equipment and the transportation preparation time, thereby significantly improving the continuity and overall efficiency of the construction process.

[0016] 2. Greatly enhanced driver comfort and driving safety: The unique connection components of the utility model, including spring damping plates and telescopic rods, form an efficient damping system, which effectively absorbs and reduces the vibrations generated by the rolling wheel during operation, and greatly reduces the impact of these vibrations on the tractor. This not only significantly improves the driver's comfort during construction and reduces fatigue caused by long-term operation, but also improves driving stability and reduces the risk of operational errors caused by vibration, thereby greatly enhancing safety during construction.

[0017] In summary, the utility model can improve construction efficiency and transportation convenience, enhance the driver's comfort and driving safety, and is suitable for the field of road construction technology. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings. Embodiment

[0026] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, but should not be construed as a limitation to the present invention.

[0027] As Figures 1 to 5 shown, a road surface intelligent compaction device includes a traction component 1. The traction component 1 includes a traction frame 11, which is connected to the tractor as the front-end part. It is designed to be strong and durable and can withstand the weight of the rolling wheel and the forces during the compaction operation. The rolling wheel 2 located behind the traction component is the core of the compaction operation. Its weight and material ensure effective road surface compaction. In particular, the rolling wheel is designed with a three-point convex shape, generating high potential energy when rolling and impacting the road surface for compaction. This design not only enhances the compaction effect but also improves the operation efficiency. The limit sliding groove 12 on the traction frame allows the rolling wheel to slide up and down during operation, automatically adjusting the compaction force using this high potential energy to adapt to the unevenness of the road surface, ensuring uniform and effective compaction under different road conditions. The lifting component 3 can control the position of the rolling wheel before and after the operation, and cooperate with the auxiliary wheel 13 to support the weight of the device during towing, ensuring the normal driving of the tractor and protecting the road surface. In addition, the design of the connection component 4 is aimed at reducing the vibration to the tractor during operation, improving the driving comfort and vehicle stability, making the entire compaction device easy to operate, highly adaptable, and significantly improving the compaction efficiency and operation quality. Through this three-point convex-shaped rolling wheel, the device can generate continuous impact forces during rolling, deeply compacting the road surface material and further enhancing the overall performance of the compaction operation.

[0028] As Figure 3 and Figure 5As shown, the lifting component 3 of the road surface compactor uses a hydraulic system, which includes a hydraulic cylinder barrel 31 installed on the towing frame 11 and a hydraulic rod 32 inside. The end of the hydraulic rod is equipped with a wheel axle sleeve 33, which is connected to the wheel axle of the rolling wheel 2. This design enables the rolling wheel to be quickly lifted off the ground by operating the hydraulic system after the construction task is completed, and work in coordination with the auxiliary wheel 13 to quickly convert the device into the towing mode. This innovative design avoids the complex disassembly and reassembly processes that traditional compaction equipment must go through during the transfer process, significantly reducing the idle time of the equipment and the preparation time before transportation. This not only simplifies the operation process but also significantly improves the continuity of the construction process and the overall operation efficiency, providing a more efficient and convenient solution for road surface construction.

[0029] As Figure 4 shown, the design of the connection component 4 aims to provide a stable and shock-absorbing connection method for the road surface compactor. This component consists of fixed wing plates 41 on the towing frame 11. A sliding shaft 42 is installed between the two fixed wing plates, and a sleeve 43 is slidably arranged on the sliding shaft. A spring shock-absorbing plate 44 is provided on the sleeve. Such a configuration is designed to absorb and relieve the vibrations generated during the operation through the spring shock-absorbing plate, protecting the tractor and the compactor from damage, while ensuring the stability of the connection and the comfort of operation.

[0030] As Figure 4 shown, the connection component 4 further optimizes its shock-absorbing performance. A number of telescopic rods 441 are installed on the spring shock-absorbing plate 44, and the other ends of these telescopic rods are connected to the fixed wing plate 41, forming a flexible support structure. In addition, shock-absorbing springs 442 are equipped on the outside of the telescopic rods 441. These shock-absorbing springs work in coordination with the telescopic rods. When the road surface compactor encounters bumps or vibrations during operation, they can effectively absorb and buffer these vibrations, thereby protecting the tractor and the compactor from excessive impacts and improving the stability and durability of the entire system.

[0031] As Figure 4 shown, the spring shock-absorbing plate 44 of the connection component 4 is equipped with a tractor joint 443 at the end. This joint is designed to be connected to the towing device of the tractor. Such a configuration not only ensures that the road surface compactor can be firmly combined with the tractor but also effectively reduces the vibrations generated during the operation to the lowest level through the shock-absorbing system composed of the spring shock-absorbing plate and the telescopic rods 441 and shock-absorbing springs 442 on it, improving the comfort of the driver and the operation safety of the equipment, while also protecting the tractor and the compactor from damage caused by vibrations.

[0032] As Figure 2As shown, the traction frame 11 adopts an "I"-shaped steel beam structure. This structural design provides extremely high strength and stability, enabling the traction frame to withstand various forces and pressures during road compaction operations. Due to the good bending resistance performance and relatively high sectional moment of inertia of the "I"-shaped steel beam, it can effectively disperse and bear the weight from the rolling wheel as well as the vibrations and impacts generated during operation, thus ensuring the reliability and durability of the entire road compaction device. In addition, the "I"-shaped steel beam structure is also convenient for installation and maintenance, further enhancing the overall performance and usage efficiency of the device.

[0033] Working process:

[0034] The working process of this road compaction device is as follows: First, the tractor is connected to the compaction device through the traction frame 11 of the traction assembly 1. The traction frame adopts an "I"-shaped steel beam structure, ensuring the stability of the connection. At the start of the operation, the hydraulic system of the lifting assembly 3 lowers the rolling wheel 2 and retracts the auxiliary wheel 13. The rolling wheel rolls on the road surface with its three-point convex shape, generating high-position potential energy for impact compaction. At the same time, the limit sliding groove 12 allows the rolling wheel to automatically adjust the compaction force according to the road surface unevenness. The spring shock-absorbing plate 44, the telescopic rod 441, and the shock-absorbing spring 442 of the connection assembly 4 work together to absorb and buffer the vibrations during the operation, protecting the tractor and the compaction device. After the operation is completed, operate the hydraulic system, and the lifting assembly 3 quickly lifts the rolling wheel off the ground. The auxiliary wheel 13 supports the weight of the device, converting it into a towed mode for convenient transfer. The entire process simplifies the operation process, improving the compaction efficiency and operation quality.

It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation.
