Description
Technical Field
[0001] This utility model relates to a vibratory rod height adjustment device and a slipform paver, belonging to the technical field of road construction machinery. Background Technology
[0002] In road construction, the height adjustment of the vibrator of a slipform paver directly affects the compaction and construction quality of the concrete pavement. Currently, the mainstream adjustment method in the industry still relies on a rigid frame connection structure, with drive mechanisms mainly divided into mechanical and hydraulic types. However, both have significant technical limitations: mechanical adjustment requires manual operation of bolts, gears, and other components to achieve height adjustment, which is not only cumbersome and time-consuming to install and disassemble, but also discontinuous, unable to achieve precise fine-tuning, and extremely inconvenient to operate; while hydraulic adjustment provides stable power output, it is affected by factors such as changes in hydraulic oil viscosity and pipeline leaks, making it difficult to accurately control the adjustment precision, easily leading to height deviations and inconsistent vibration depths. More importantly, both traditional structures lack a real-time linkage mechanism with the construction conditions, and cannot dynamically and intelligently adjust based on changes in concrete gradation, material moisture differences, and compaction feedback during the paving process. This makes it difficult to adapt to complex and ever-changing construction needs, thus affecting the uniformity of the pavement layer and the stability of project quality. Summary of the Invention
[0003] To address the problems existing in the prior art, this utility model provides a vibratory rod height adjustment device and a slipform paver, which are easy to operate and can meet the requirements of different construction widths.
[0004] To achieve the above objectives, this utility model employs a vibratory rod height adjustment device, comprising a telescopic electric cylinder, a linkage mechanism, a crossbeam support, an electrical control system, an installation assembly, and multiple vibratory rods. The installation assembly is connected to a slipform paver. The vibratory rods are arranged in an array and installed on the crossbeam support. The linkage mechanism is hinged to the crossbeam support and the installation assembly, respectively. The two ends of the telescopic electric cylinder are correspondingly hinged to the linkage mechanism and the installation assembly. The electrical control system is electrically connected to the telescopic electric cylinder. By controlling the telescopic extension and retraction of the telescopic electric cylinder, the linkage mechanism is driven to move synchronously, thereby adjusting the overall height of multiple vibratory rods while maintaining the horizontal position of the vibratory rods unchanged during the adjustment process.
[0005] As an improvement, the linkage mechanism includes an upper connecting plate, a middle connecting plate, and a lower connecting plate. One end of each of the upper, middle, and lower connecting plates is hinged to the mounting assembly. The upper side of the upper connecting plate away from the mounting assembly is hinged to the telescopic electric cylinder, and the lower side is hinged to the middle connecting plate. The end of the middle connecting plate away from the mounting assembly is hinged to the lower connecting plate, and the end of the lower connecting plate away from the mounting assembly is hinged to the crossbeam support, forming a multi-link linkage structure.
[0006] As an improvement, the upper connecting plate is bent into an L-shape. The long end of the L-shaped upper connecting plate is hinged to the mounting assembly, and the short end is hinged to the telescopic electric cylinder. The bent part of the upper connecting plate is hinged to the middle connecting plate through the first short plate. The end of the middle connecting plate away from the mounting assembly is hinged to the upper part of the second short plate. The lower part of the second short plate is connected to the crossbeam connecting clamp. The end of the lower connecting plate away from the mounting assembly is hinged to the middle part of the second short plate.
[0007] As an improvement, the telescopic electric cylinder includes a motor and a cylinder body, with the motor and cylinder body being connected in a transmission connection. The motor drives the cylinder body to extend and retract to actuate the linkage mechanism.
[0008] As an improvement, the crossbeam support is composed of multiple crossbeam segments spliced together by a detachable connection structure.
[0009] As an improvement, the vibrator is mounted on the crossbeam support via a snap-fit structure.
[0010] As an improvement, the beam support is hinged to the linkage mechanism via a beam connecting clamp, and the beam connecting clamp and the beam support are detachably connected.
[0011] As an improvement, the mounting assembly includes a fixed frame and a connecting rod slide, one end of which is fixedly connected to the fixed frame and the other end is slidably connected to the forming mold of the slipform paver; one end of the telescopic electric cylinder and one end of the connecting rod mechanism are respectively hinged to the fixed frame.
[0012] In a second aspect, this utility model also provides a slipform paver, wherein the slipform paver is equipped with the aforementioned vibratory rod height adjustment device.
[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. Precise and efficient height adjustment with strong adaptability. The telescopic cylinder is controlled by an electronic control system, driving the linkage mechanism synchronously to achieve flexible adjustment of the overall height of multiple vibrators. This allows for real-time adaptation to the vibration depth requirements of different concrete gradations. Compared to traditional mechanical or hydraulic adjustment methods, the electronically controlled drive combined with the linkage structure offers higher adjustment precision and faster response. It can optimize the vibration depth based on concrete density feedback during construction, ensuring uniform and stable paving quality.
[0014] 2. Stable vibration posture and good construction effect. The hinged design of the linkage mechanism, crossbeam support, and installation components ensures that the horizontal position of the vibrator remains constant during height adjustment. This avoids the vibrator shifting forward or backward during adjustment, ensuring the continuity and consistency of the vibration area, effectively preventing local under-vibration or over-vibration of concrete, and further improving the construction and forming effect.
[0015] 3. The structure is rationally designed and easy to operate. Multiple vibrating rods are arranged in an array on the crossbeam support. Combined with the linkage drive of the telescopic electric cylinder and linkage mechanism, there is no need to adjust the height of each individual vibrating rod; overall synchronous adjustment is achieved, significantly reducing operational complexity and saving construction adjustment time. Simultaneously, the integrated design of the electrical control system eliminates the need for manual intervention, enabling automated and precise control and reducing labor costs.
[0016] 4. Wide adaptability and strong practicality. The device can be flexibly connected to slipform pavers through installation components, and can be adapted to different models of slipform pavers. The array-type installation and overall adjustment structure can meet the vibration requirements of paving construction of different widths. With the subsequent design of splicable crossbeams and adjustable vibrator spacing, the applicable scenarios of the device are further expanded and the construction flexibility is improved.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this application will be described in detail below through specific embodiments. It should be understood that the embodiments of this application and the specific features in the embodiments are detailed descriptions of the technical solutions of this application, rather than limitations on the technical solutions of this application. In the absence of conflict, the embodiments of this application and the technical features in the embodiments can be combined with each other.
[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0021] like Figures 1-5 As shown, a vibratory ram height adjustment device includes a telescopic electric cylinder, a linkage mechanism, a crossbeam support 3, an electrical control system, an installation component, and multiple vibratory rams 4. The installation component is connected to a slipform paver, providing a stable installation and strong adaptability, compatible with different paver models. The multiple vibratory rams 4 are arranged in a uniform array and installed on the crossbeam support 3, ensuring full coverage of the vibration area without dead corners and guaranteeing uniform compaction of the concrete pavement. The linkage mechanism adopts a linkage structure formed by multiple component hinges, with its two ends hinged to the crossbeam support 3 and the installation component, respectively. The two ends of the telescopic electric cylinder are correspondingly hinged to the linkage mechanism and the installation component. This hinge combination design makes power transmission smoother and can constrain the movement trajectory. The electrical control system is electrically connected to the telescopic electric cylinder, driving the telescopic electric cylinder to extend and retract through output control signals, thereby driving the linkage mechanism to move synchronously and achieve stepless and precise adjustment of the overall height of multiple vibratory rams 4, eliminating the need to adjust each individual vibratory ram 4 individually. Adjustments are made to significantly improve adjustment efficiency; at the same time, the articulated transmission design of the linkage mechanism can strictly ensure that the front and rear horizontal position of the vibrator 4 remains unchanged throughout the height adjustment process, avoiding problems such as under-vibration, over-vibration, or misalignment of the vibration area caused by positional deviation, and further ensuring the stability and consistency of construction quality.
[0022] As an improved embodiment, such as Figure 2 , Figure 5The upper connecting plate 1 adopts an L-shaped structure formed by integral bending. This structure design takes into account both the adaptability of installation space and the stability of power transmission, and can achieve a multi-directional hinged layout without additional splicing. The long plate end of the L-shaped upper connecting plate 1 is hinged to the corresponding mounting component, and the short plate end is hinged to the output end of the telescopic electric cylinder to ensure efficient transmission of driving force. The bending point of the upper connecting plate 1 is hinged to the first short plate 12, which is hinged to one end of the middle connecting plate 9 to achieve a smooth transition of power to the intermediate transmission component. The end of the middle connecting plate 9 away from the mounting component is hinged to the upper part of the independently set second short plate 13, and the lower part of the second short plate 13 is fixedly connected to the crossbeam connecting clamp 5. The second short plate 13 forms a connecting transfer node between the linkage mechanism and the crossbeam support 3. At the same time, the end of the lower connecting plate 8 away from the mounting component is hinged to the middle part of the second short plate 13, forming a linkage structure of the upper connecting plate 1, the first short plate 12, the middle connecting plate 9, the second short plate 13 and the lower connecting plate 8.
[0023] The specific layout of this multi-stage hinge can further optimize the power transmission path, so that the linear driving force of the telescopic electric cylinder can be accurately converted into the vertical lifting and lowering motion of the crossbeam connecting clamp 5 through the coordinated rotation of each connecting plate. Moreover, through the constraint of each hinge point, the horizontal displacement of the crossbeam support 3 can be limited to the maximum extent, ensuring that the vibrator 4 always maintains a constant front and rear horizontal position during the height adjustment process. At the same time, it improves the load-bearing capacity and motion stability of the entire linkage mechanism, adapting to the long-term, high-frequency construction adjustment needs.
[0024] As an improved embodiment, such as Figure 2 As shown, the telescopic electric cylinder specifically includes a motor 2 and a cylinder body 10. The motor 2 and the cylinder body 10 are connected by a screw drive structure, which has high transmission efficiency and high positioning accuracy. The motor 2 receives the drive signal converted by the driver from the electronic control system and operates precisely. Through the screw drive, the rotational motion is converted into linear motion, driving the cylinder body 10 to extend and retract smoothly along the axial direction. This outputs a continuous and stable driving force to the linkage mechanism, driving the linkage mechanism to move in precise linkage, ensuring the response speed and control accuracy of the height adjustment of the vibrating rod 4, and adapting to the dynamic adjustment needs during construction.
[0025] As an improved embodiment, as shown in Figures 3 and 4, the crossbeam support 3 adopts a modular splicing design, assembled from multiple independent crossbeams of uniform specifications through a detachable connection structure. The mating ends of adjacent crossbeams are integrally formed with flanges, and bolt holes are provided on the flanges for inserting and tightening locking bolts. This ensures a tight fit between the two crossbeams and guarantees the overall structural rigidity and load-bearing stability of the crossbeam support 3 after splicing, effectively resisting high-frequency vibration impacts during vibration operations. By increasing or decreasing the number of independent crossbeam segments, the total length of the crossbeam support 3 can be flexibly adjusted to precisely adapt to different paving width requirements, from narrow to wide. This eliminates the need for custom-designed integral supports for specific construction scenarios, significantly reducing equipment customization costs and inventory storage space. Simultaneously, the flange and locking bolt connection method makes the disassembly, assembly, and length adjustment of the crossbeams convenient and efficient, allowing for rapid device adaptation according to the construction plan, improving construction preparation efficiency and equipment turnover flexibility.
[0026] As an improved embodiment, such as Figure 4 As shown, the vibratory rod 4 is installed on the crossbeam support 3 via a quick-release snap-fit structure 11. The snap-fit structure 11 includes a retainer connected to the vibratory rod 4 and a locking ring adapted to the crossbeam support 3. During installation, the crossbeam support 3 is snapped into the retainer and fixed by the locking ring. During disassembly, it can be removed simply by loosening the locking ring, making the operation convenient and efficient. In addition, the snap-fit structure 11 has a certain buffer margin, which can reduce the impact of vibration on the installation structure during vibration operation, improve the stability of the vibratory rod 4 installation, and avoid loosening problems caused by long-term high-frequency vibration.
[0027] As an improved embodiment, such as Figure 2 As shown, the crossbeam support 3 is hinged to the lower connecting plate 8 of the linkage mechanism via the crossbeam connecting clamp 5. The crossbeam connecting clamp 5 adopts a split clamping structure, including an upper clamp and a lower clamp that cooperate with each other, and is fixed to the preset installation position of the crossbeam support 3 by bolts. This detachable connection design facilitates the precise alignment and installation of the crossbeam support 3 and the linkage mechanism, and allows for individual replacement when parts are damaged, reducing maintenance costs. At the same time, the hinged connection method can adapt to the rotation trajectory of the linkage mechanism, ensuring smooth power transmission and avoiding stress concentration problems caused by hard connections.
[0028] As an improved embodiment, such as Figure 2As shown, the installation assembly includes a fixed frame 7 and two connecting rod slides 6. The connecting rod slides 6 are integrally machined from high-strength alloy profiles into an L-shaped structure, combining lightweight and high rigidity. One end of the slides 6 is welded to the fixed frame 7 to form a stable connection, while the other end is slidably connected to a T-shaped track pre-set on the forming mold of the slipform paver. By synchronously sliding the two connecting rod slides 6, the entire adjustment device can be driven to smoothly adjust the installation position along the length of the forming mold, adapting to different construction layout requirements. The fixed ends of the telescopic electric cylinder and the connecting rod mechanism are both hinged to the fixed frame 7. The fixed frame 7 adopts a rigid frame structure, with balanced force distribution, providing a stable installation benchmark and support for the entire device, effectively constraining the movement trajectory of each component, and improving the stability of the device during operation.
[0029] In a second aspect, this utility model also provides a slipform paver, wherein the frame of the slipform paver is equipped with the vibrator height adjustment device described in any of the above embodiments via an installation assembly, and the installation is stable; The height adjustment device for the vibrator is precisely matched with the paving operation process of the slipform paver. During construction, the overall height of the vibrator 4 can be controlled in real time through the electrical control system, flexibly adapting to the vibration depth requirements of different gradations of concrete materials, while ensuring the continuity and uniformity of the vibration area, effectively improving the density and forming quality of the concrete pavement.
[0030] In addition, the device features a multi-segment splicing crossbeam support 3 and a vibratory rod 4 installation structure with adjustable spacing via a snap-fit structure 11, which can adapt to the paving operation requirements of slipform pavers of different widths without the need for additional adaptation and modification. The stable transmission design of the linkage mechanism and the precise drive of the telescopic electric cylinder further ensure the reliability of vibration adjustment during continuous operation of the paver, reduce the frequency of manual intervention, improve construction efficiency and operational safety, and expand the applicable scenarios and construction quality limits of slipform pavers.
[0031] Furthermore, those skilled in the art will understand that although some embodiments described herein include certain features found in other embodiments but not others, combinations of features from different embodiments are also within the scope of protection of this utility model and form different embodiments. For example, in the embodiments described above, those skilled in the art can use them in combination based on known technical solutions and the technical problems to be solved by this application.
