Description

Technical Field

[0001] This utility model relates to the field of municipal road construction, specifically a vibratory leveling device for municipal road construction. Background Technology

[0002] In municipal road construction, conventional vibratory grading operations typically rely on vibratory grading devices to compact and level the paving materials, ensuring that the road surface flatness and compaction meet design requirements. Currently, at large road construction sites, heavy-duty self-propelled vibratory grading equipment equipped with drive systems has enabled mechanized operations, meeting the demands for high-efficiency and high-quality construction.

[0003] However, in narrow spaces such as urban road maintenance, sidewalk paving, and alleyway leveling, large equipment often cannot enter the site or begin operations smoothly due to its large size, limited maneuverability, and transportation difficulties. In such construction scenarios, construction workers generally still use hand-push or simple mechanical vibratory leveling devices for operation, which usually rely on manual pushing to move and operate. For example, patent CN219385910U discloses a vibratory leveling device for municipal road construction, including a base, a movable wheel fixedly connected to the middle of the lower outer surface of the base, a roller movably connected to one side of the lower outer surface of the base, a first connecting rod fixedly connected to one side of the upper outer surface of the base, a crossbar fixedly connected to the outer wall of the first connecting rod, a protective cover fixedly connected to the upper outer surface of the base, a telescopic component provided on the upper outer surface of the protective cover, and a vibratory leveling component provided on the inner wall of the protective cover. The telescopic components allow for adjustment of the distance between the vibratory plate and the ground, enabling better leveling. When not in use, the vibratory plate can be raised to prevent it from scraping the ground during movement. The leveling components also facilitate the installation and removal of the vibratory plate.

[0004] This method has obvious technical problems: the speed of manual movement is unstable, which can easily cause uneven leveling, and the labor intensity is high and the efficiency is low, which seriously affects the construction quality and progress. Existing patent technologies mainly focus on optimizing the structure or vibration mode of the leveling mechanism itself, but they do not provide an effective solution to the problem of how to achieve uniform automatic movement of the device in a narrow construction space to improve the leveling effect and construction efficiency.

[0005] Therefore, it is still necessary to develop a road construction vibratory leveling device that is suitable for confined spaces and has self-driving capabilities to improve construction efficiency and quality under such conditions. Utility Model Content

[0006] This utility model provides a vibratory leveling device for municipal road construction to solve the technical problem of unstable travel speed caused by manually pushing the vibratory leveling device in a narrow construction environment.

[0007] According to one aspect of this utility model, a municipal road construction vibratory leveling device is provided, comprising a frame as a base platform to provide support; a moving component mounted on the frame for moving the frame, wherein one moving component is respectively provided on each side of the frame, and each moving component includes a rotary motor and multiple moving wheels, the rotary motor being drivenly connected to two moving wheels to drive the moving wheels to rotate, and the rotary motors of the two moving components operating independently; a vibratory leveling component for vibrating and leveling the road surface, the vibratory leveling component being located between the two moving components; and a lifting component mounted on the frame for driving the vibratory leveling component to move up and down, so that the vibratory leveling component approaches or moves away from the ground.

[0008] Optionally, the two moving wheels of the same moving component are driven by a belt pulley assembly, and the output shaft of the rotary motor is connected to one of the moving wheels via a gear assembly.

[0009] Optionally, the gear assembly includes a driving gear and a driven gear that mesh with each other. The driving gear is fixed on a rotary motor, and the driven gear is coaxially and fixedly connected to the corresponding moving wheel. The number of teeth on the driving gear is less than the number of teeth on the driven gear.

[0010] Optionally, the vibratory leveling assembly includes a mounting plate and a vibrating plate, with a vibrating motor mounted on the mounting plate and the output shaft of the vibrating motor connected to the vibrating plate.

[0011] Optionally, a damper is provided between the mounting plate and the vibrating plate, and a buffer spring is sleeved on the outside of the damper.

[0012] Optionally, the lifting assembly includes a fixed frame, a lead screw, and a drive motor. The fixed frame is fixedly connected to the frame. The lead screw is vertically arranged inside the fixed frame and rotates with the fixed frame. The output shaft of the drive motor is drivenly connected to the lead screw to drive the lead screw to rotate. A first slider is threaded onto the lead screw. The first slider is fixedly connected to the vibrating and leveling assembly so that the movement of the first slider drives the vibrating and leveling assembly to rise and fall.

[0013] Optionally, the frame is provided with a guide rod parallel to the lead screw, a second slider is slidably connected to the guide rod, a fixing rod is provided between the first slider and the second slider, and a mounting seat is provided on the fixing rod, the mounting seat being fixedly connected to the mounting plate.

[0014] Optionally, a connecting frame is fixedly installed on the first slider, and the connecting frame is provided with a connecting seat for supporting it on the ground.

[0015] Optionally, a positioning pin is fixedly provided at the bottom of the connector.

[0016] Optionally, baffles are provided at both ends of the frame along the moving direction, and the lowest position of the baffles is not lower than the lowest point of the moving wheel.

[0017] In summary, this application includes at least one of the following beneficial technical effects:

[0018] In this design, the frame serves as the supporting foundation for the entire device, upon which independent moving components are arranged on the left and right sides. Each moving component is equipped with a rotary motor and two moving wheels. The rotary motor is connected to the moving wheels via a gear or belt structure, forming a stable drive transmission path. By directly using the rotary motor as the driving force source, the device can automatically move forward at a constant speed without manual pushing. The motors of the two moving components are controlled separately, enabling differential steering as needed, thereby significantly improving operability and maneuverability in narrow sections, winding passages, or complex sites. Compared to manual pushing, this electric drive structure ensures that the equipment maintains a stable and controllable forward speed during operation, significantly reducing uneven leveling caused by sudden speed fluctuations and ensuring the compaction and leveling quality of the construction road surface. Furthermore, the leveling component is positioned centrally between the two moving components, and its reasonable center of gravity distribution facilitates the even transmission of vibration force to the ground. The lifting component can be adjusted up and down via a screw mechanism, actively lowering the vibrating plate to contact the ground when leveling is required; it can be raised during relocation or movement to avoid friction with the ground. The introduction of this lifting structure further enhances the device's efficiency in switching functions and its adaptability to terrain at different construction stages.

[0019] In summary, this device effectively solves the problems of unstable movement, low efficiency, and uneven leveling of traditional manual vibratory leveling equipment in narrow construction environments. It has good self-driving ability, stability, and construction quality control capabilities, and significantly improves the level of mechanized operation in municipal road maintenance and paving.

[0027] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered below.

[0028] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0029] This application discloses a vibration leveling device for municipal road construction.

[0030] Reference Figure 1 This utility model provides a municipal road construction vibratory leveling device, suitable for construction sites with limited space such as urban sidewalks, small alleys, and road maintenance strips. It is used to compact and level paving materials such as asphalt, gravel, and cement base layers, thereby improving road construction quality and work efficiency. Compared with existing simple vibratory leveling equipment that relies on manual pushing, this device incorporates a self-driving mechanism and an adjustable vibration structure, enabling uniform speed movement and high-frequency vibratory leveling operations within limited space. This effectively overcomes the problems of uneven leveling, high labor intensity, and slow construction progress associated with traditional methods.

[0031] The overall structure of the municipal road construction vibratory leveling device includes multiple modules such as a frame 1, a moving component 2, a vibratory leveling component 3, and a lifting component 4. These modules are integrated onto a compact frame 1, providing excellent collaborative working capabilities. The frame 1 serves as the basic platform for the device, supporting the installation and structure of all functional components. Symmetrical moving components 2 are mounted on either side of its bottom. Each moving component 2 includes a rotary motor 22 and moving wheels 21, with the motor driving the wheels to achieve automatic movement of the device. The vibratory leveling component 3, including a vibratory motor 33, a mounting plate 31, and a vibrating plate 32, is installed in the middle of the frame 1 to generate continuous and uniform vibration compaction on the construction surface. The vibratory leveling component 3 is driven by a lifting mechanism, allowing it to move up and down while maintaining close contact with the ground during operation and automatically lifting to prevent wear during movement. During operation, the operator can activate the two rotary motors 22 via the control system to achieve adaptive movement of the device on straight or turning paths; simultaneously, the operator controls the lifting component 4 to adjust the contact state between the vibrating plate and the ground, and activates the vibratory motor 33 to generate high-frequency vibration, thereby achieving high-quality road leveling operations.

[0032] Reference Figure 1 and Figure 2 In this embodiment, the moving components 2 of the vibratory leveling device are symmetrically arranged on the left and right sides of the frame 1, with each side equipped with an independent moving drive unit to drive the entire device to move forward at a constant speed and turn flexibly on the road surface. Each set of moving components 2 mainly includes: a rotary motor 22, two moving wheels 21, a gear assembly, and a pulley assembly. The two moving wheels 21 are the first moving wheel and the second moving wheel, respectively, to realize the transmission of driving force and the coordinated work of the wheelset.

[0033] Specifically, the rotary motor 22 is fixedly mounted on the side bracket of the frame 1, and its output shaft is connected to a gear assembly. This gear mechanism consists of a driving gear 61 and a driven gear 62. The driving gear 61 is fixed to the motor output shaft, and the driven gear 62 is coaxially mounted with the first moving wheel. The driving gear 61 has fewer teeth than the driven gear 62, thereby reducing the rotational speed and amplifying the torque during transmission, ensuring that the moving device still has sufficient propulsion force under low-speed, high-load conditions.

[0034] To achieve synchronous rotation of the same wheelset, the second moving pulley is connected to the first moving pulley via a pulley assembly. This belt drive system includes pulleys mounted at the ends of the two axles and a rubber synchronous belt covering them, used to transmit the rotational motion of the first moving pulley to the second moving pulley, thus achieving wheelset linkage. Belt drive is a friction drive structure, which has advantages such as simple structure, flexible arrangement, low cost, and certain shock absorption performance.

[0035] The rotary motors 22 of the two moving components 2 are independently controlled, and the control system can adjust the speed of the left and right motors separately to achieve differential drive function. When the speeds of the left and right wheelsets are equal, the device moves forward at a constant speed in a straight line; when the speed of one side is faster than the other, the device will turn towards the slower side, thereby achieving precise path correction and steering control. This differential drive design eliminates the traditional steering mechanism, making the structure simpler and the response more flexible. It is particularly suitable for use in narrow working conditions with limited turning radii, such as sidewalks, urban alleyways, and construction joint edges.

[0036] Reference Figure 3 In this embodiment, the vibratory leveling component 3 is located in the middle of the frame 1, between the left and right sets of moving components 2. The vibratory leveling component 3 is connected to the slider of the lifting component 4 through the mounting plate 31, so that the height of the vibratory leveling component 3 can be adjusted in the vertical direction as the lifting component 4 moves up and down, so that the vibratory plate 32 is close to the ground during operation, or rises during movement to avoid contact with the ground.

[0037] The vibratory leveling assembly 3 includes a mounting plate 31, a vibratory motor 33, a vibratory pull plate, a vibratory plate 32, a damper 7, and a buffer spring 8. The mounting plate 31 supports the vibratory motor 33 and the vibrating structure. The vibratory motor 33 is mounted on the mounting plate 31, and its output shaft is connected to an eccentric structure and to the drive end of the vibratory pull plate. The vibratory pull plate has a structure with one end fixed and the other end freely vibrating; its free end is connected to the vibratory plate 32. After the vibratory motor 33 is powered on, its output shaft rotates and, through the eccentric structure, drives the vibratory pull plate to vibrate periodically up and down, thereby driving the vibratory plate 32 to achieve reciprocating vibration.

[0038] The vibrating plate 32 is located below the vibrating and leveling assembly 3 and serves as the vibrating and leveling working surface in direct contact with the ground, used for compacting the laid material. To reduce the transmission of vibration to the upper structure and buffer impact, multiple dampers 7 are installed between the mounting plate 31 and the vibrating plate 32, and each damper 7 is externally fitted with a buffer spring 8. The dampers 7 can be made of hydraulic or rubber materials to attenuate high-frequency vibrations; the buffer springs 8 are used to absorb rebound impacts, stabilize vibration amplitude, and prevent structural fatigue.

[0039] In this embodiment, the high-frequency excitation force generated by the vibratory leveling component 3 can act on the construction ground, causing the road surface material to be compacted and tightly bound under vibration, effectively improving the overall smoothness and structural stability of the road surface. Compared with the traditional manual compaction method, this vibratory leveling component 3 achieves uniform and continuous operation through electric drive excitation, which not only reduces the intensity of manual labor, but also improves the uniformity of the leveling effect and construction efficiency. It is particularly suitable for narrow construction scenarios where the paved surface is locally uneven and the corner areas are difficult to compact.

[0040] In other alternative embodiments, the vibration motor 33 can be replaced with a hydraulic eccentric vibrator to meet the needs of higher frequencies or greater excitation forces; the vibration pull plate can be replaced with a crank-rocker structure to further improve the stability of vibration control; the damper 7 can be an air spring or a magnetorheological damper 7 to meet the dynamic response performance requirements under different working conditions. Through the optimization of the above structure and configuration, the vibration leveling assembly 3 of this embodiment has the technical advantages of simple structure, high excitation efficiency, excellent damping performance, and strong adaptability.

[0041] Reference Figure 1 and Figure 3 In this embodiment, the lifting assembly 4 is located in the middle of the upper structure of the frame 1, and is used to drive the vibratory leveling assembly 3 to move vertically, thereby achieving adjustable control of the contact state between the vibratory plate 32 and the ground, thus meeting the operational needs under different terrains and construction rhythms. The lifting assembly 4 includes multiple components such as a fixed frame 41, a drive motor 43, a lead screw 42, a first slider 44, a guide rod 45, a second slider 46, a fixed rod 47, and a mounting base 48. The overall structure is compact, the transmission is stable, and the lifting response is sensitive.

[0042] The fixed frame 41 is bolted to the inner longitudinal beam of the frame 1 and is vertically arranged to provide stable support for the lead screw 42 and the guide rod 45. The lead screw 42 is vertically arranged at the central axis of the fixed frame 41, and the drive motor 43 is mounted on the upper end of the fixed frame 41, transmitting power output to the upper end of the lead screw 42 through a coupling. After the drive motor 43 is powered on, it drives the lead screw 42 to rotate.

[0043] A first slider 44 is threadedly connected to the lower part of the lead screw 42. As the first slider 44 moves up and down along the lead screw 42, it drives the vibrating and leveling assembly 3 mounted on it to rise and fall accordingly. To improve the guiding stability of the slider's movement, a guide rod 45 is arranged parallel to one side of the lead screw 42. A second slider 46 is mounted on the guide rod 45 and can slide up and down on the guide rod 45. The first slider 44 and the second slider 46 are connected by a fixing rod 47. A mounting base 48 is installed in the middle of the fixing rod 47 to fix the upper mounting plate 31 of the vibrating and leveling assembly 3, thereby achieving overall linkage between the vibration mechanism and the rising and falling slider.

[0044] Through the screw 42-slider transmission and the guide rod 45, the positional accuracy and posture stability of the vibratory leveling component 3 are effectively guaranteed during the lifting process, preventing uneven vibration or interference caused by the tilting of the vibratory plate 32 during operation. Furthermore, the lifting structure allows the vibratory leveling component 3 to be lifted off the ground when the equipment is not in operation, avoiding wear and tear on the vibratory plate 32 caused by prolonged dragging and extending its service life. In addition to enabling the switching between operation and retraction of the vibratory leveling component 3, the lifting operation can also flexibly adjust the initial compaction height of the vibratory plate 32 to accommodate paving materials of different thicknesses or unevenness, optimizing vibration efficiency and improving compaction consistency and construction quality.

[0045] In other embodiments, the connection structure between the drive motor 43 and the lead screw 42 can be replaced with a worm gear reduction mechanism to obtain higher torque output. The guide mechanism can also adopt a double guide rail structure to improve lateral anti-deviation capability. The slider material can be selected from high-strength nylon or aluminum alloy according to the application scenario to reduce structural weight and improve response speed.

[0046] To effectively distribute the dynamic load generated during the vibration leveling operation and prevent the excitation force from being directly transmitted to the lead screw 42 and the slider, which could cause the lead screw 42 to bend or the lifting transmission to become unstable, a synchronously lifting ground support and positioning structure is installed at the bottom of the vibration leveling assembly 3. This structure includes a connecting frame 9, a connecting seat 10, and a positioning pin 11, which rises and falls together with the vibration leveling assembly 3. During the vibration leveling operation, it contacts the ground and bears the reverse load, and is an important component of the entire structural force closed loop.

[0047] The connecting frame 9 is fixedly installed at the lower end of the first slider 44 and moves synchronously with the lifting mechanism. The lower part of the connecting frame 9 is connected to the connecting seat 10, which contacts the ground and supports the dynamic force of the entire vibrating and leveling assembly 3. The connecting seat 10 adopts a plate-like or frame structure, with several mounting holes at the bottom for inserting positioning pins 11. The structural dimensions and contact area of ​​the connecting seat 10 can be adjusted according to different ground materials to improve support stability.

[0048] The positioning pin 11 is located at the bottom of the connecting seat 10 and is installed via an interference fit or locking mechanism. It is used to insert into shallow pre-drilled holes or soft pavement layers in the road surface. After the vibratory leveling assembly 3 descends to the working position, the connecting seat 10 contacts the ground before or simultaneously with the pin, which embeds itself into the ground surface to construct a rigid support path. This directly guides the reaction force generated during vibration to the ground, avoiding its effect on the lead screw 42 or guide rod 45, thereby improving the overall stability and structural lifespan of the system.

[0049] This structure forms a rigid connection with the vibratory plate assembly 3, ensuring that the relative position remains consistent throughout the lifting process. A reasonable gap is provided between the connecting seat 10 and the vibratory plate 32 to ensure that the support surface is stressed during vibration, rather than the lead screw 42 bearing cantilever pressure, thus forming a "bottom-support" structural force path with excellent dynamic response performance and structural protection. Compared to traditional structures that rely solely on the lifting lead screw 42 to suspend the vibratory plate, this solution effectively alleviates the bending, loosening, and even fatigue damage problems caused by dynamic loads on the lead screw 42 transmission pair by setting up a synchronously grounded support structure, making it particularly suitable for high-frequency vibration and long-term continuous operation scenarios. Simultaneously, the pin insertion method further improves the coupling stiffness between the support point and the ground, preventing slippage or localized jumping of the support.

[0050] In alternative solutions, the pin structure can be replaced with a liftable strut, and the bottom of the connector 10 can also adopt a rubber buffer block or vibration damping pad structure to further improve ground flexibility or adapt to hard ground environments. In higher frequency vibration applications, an elastic support unit can be added between the connector 10 and the support foot to achieve semi-active vibration damping control.

[0051] To enhance the durability and environmental adaptability of the vibratory leveling device during construction and prevent structural damage or operational deviations caused by external obstacles such as road surface protrusions and boundary collisions, protective and limiting structures are installed at both ends of the frame 1. These structures include a front baffle 12 and a rear baffle 12, serving as the first contact protection interfaces at both ends of the device during longitudinal movement.

[0052] The baffles 12 are fixedly installed at the foremost and rearmost edges of the frame 1 along the forward and backward directions, arranged vertically, and made of rigid metal sheet or high-strength composite material, providing good impact resistance. The lower edge of each baffle 12 is lower than the bottom surface of the frame 1 but slightly higher than the ground contact point of the moving wheel 21, and its lowest point is designed to be no lower than the lowest point of the moving wheel 21, thus forming a front edge protective surface close to the ground without affecting the movement function. During the device's forward movement, if it encounters obstacles such as manhole covers, paving joints, fallen objects, or road edges, the baffles 12 can make contact with them first, and undergo slight elastic deformation or rebound locally, preventing the frame 1 body, moving wheel 21, or vibrating and leveling assembly 3 from being directly impacted. The contact surfaces of the baffles 12 are rounded or equipped with buffer strips, which helps guide the device to slide around small obstacles and reduce the risk of stopping or deviating.

[0053] A limited gap is reserved between the baffle 12 and the moving wheel 21 to ensure that the wheel assembly rotation is not interfered with. Simultaneously, it acts as a guide and buffer during obstacle encounters, direction changes, or retreat, improving the smoothness and safety of the walking path. This structure provides both basic physical limiting function and protective buffer zones in the forward and backward directions for the entire device. Through these features, during automatic movement, manual turning, or reversing, common problems such as structural interference, wheel detachment, and device tilting caused by ground debris, small obstacles, or site edges can be effectively avoided, improving operational stability and device lifespan. It is particularly suitable for scenarios such as municipal road repair and sidewalk paving where materials are densely stacked or the ground conditions are complex.

[0054] This embodiment has the following advantages: By setting symmetrically distributed moving components 2 and configuring independent rotary motors 22, the device can achieve self-driven uniform speed movement under narrow road conditions. The motor output drives the two wheels to rotate synchronously through a gear and pulley transmission structure. Under the adjustment of the control system, it can realize various path control modes such as straight-line movement, differential turning, and stationary adjustment, ensuring stable movement speed and eliminating uneven compaction caused by changes in the operating rhythm during manual pushing.

[0055] The vibratory leveling component 3 adopts an eccentric vibration motor 33 drive structure. The excitation force is transmitted to the vibrating plate 32 through the pull plate, and then applied to the road paving material. The material is fully compacted through high-frequency, low-amplitude reciprocating vibration. A damper 7 and a buffer spring 8 structure are set between the mounting plate 31 and the vibrating plate 32. While providing stable vibration output, it effectively suppresses the impact of the upper structure, thereby improving the leveling quality and structural durability.

[0056] The lifting assembly 4, driven by the drive motor 43 and linked to the vertically arranged lead screw 42, drives the first slider 44 to rise and fall. The fixed rod 47 and mounting base 48 then move the entire vibratory leveling assembly 3 vertically. The guide rod 45, in conjunction with the second slider 46, forms a rigid guiding constraint, preventing the vibratory leveling mechanism from tilting or swaying during lifting. Through lifting adjustment, the vibratory leveling assembly 3 can be quickly switched between its operating and traveling states, avoiding wear caused by contact between the vibrating plate 32 and the ground when not in operation, thus extending its service life.

[0057] The connecting frame 9, connecting seat 10 and positioning pin 11 are set below the vibration leveling component 3. The support structure rises and falls synchronously with the vibration leveling component 3. During the vibration process, it is in contact with the ground and bears the excitation reaction force, thereby avoiding the lifting structure such as the lead screw 42 and guide rod 45 from directly bearing the dynamic load, and improving the mechanical rationality and structural stability of the overall system.

[0058] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
