Description

Technical Field

[0001] This utility model relates to the field of road engineering equipment technology, and in particular, to a concrete pavement compaction device. Background Technology

[0002] Concrete pavement construction is a complex road engineering project that requires strict adherence to procedures to ensure quality. After processing, compaction is necessary to improve the strength, rigidity, stability, and smoothness of the concrete pavement, thereby extending its service life.

[0003] For example, Chinese utility model patent CN218059809U discloses a road compaction device, which relates to the field of road engineering equipment technology. It includes a compaction device body, the output end of which is provided with a connecting end, and the lower end of the connecting end is connected to a compaction plate. Based on the traditional road compaction device, a mechanism for switching between walking and working states is added, which facilitates the quick disassembly and installation of the compaction plate. The controller drives two sets of electric push rods to extend and retract, which can realize the synchronous lifting and lowering of the limit plate, thereby synchronously driving the four sets of first and second rotating plates to rotate, and thus realizing the synchronous lifting and lowering of four sets of rollers. The switching between walking and working states is realized by the alternating contact between the four sets of rollers and the compaction plate. Moreover, the reset rotation of the collar can make the three sets of positioning columns engage in the three sets of sliding grooves to realize the fixed connection of the compaction plate. At the same time, by rotating the collar, the three sets of positioning columns can slide into the three sets of slots, which can quickly remove the compaction plate, making it convenient for workers to operate.

[0004] However, in the above-mentioned compaction device, because the height of its handle is relatively fixed, and the center of gravity of the construction personnel is different under different construction conditions, the angle of force application of the construction personnel is limited, which makes the operation time-consuming and laborious, easy to cause operator fatigue, and affects the construction efficiency. Utility Model Content

[0005] This utility model provides a concrete pavement compaction device to solve the technical problems of the relatively fixed height of the handle of the existing pavement compaction device, which limits the force application angle of the construction personnel, easily leads to operator fatigue, and affects the construction efficiency.

[0006] According to one aspect of the present invention, a concrete pavement compaction device is provided, comprising a compaction body for compacting concrete pavement, a rotating component rotatably arranged vertically on the compaction body, a lifting component connected to the rotating component for vertically raising and lowering as the rotating component rotates, a push-pull handle hinged to the lifting component, and a traction component hinged to the force-applying end of the push-pull handle and the compaction body respectively, wherein the traction component is used to control the tilt angle of the push-pull handle relative to the lifting component to adjust the height of the force-applying end of the push-pull handle.

[0007] As a further improvement to the above technical solution:

[0008] Furthermore, the rotating assembly includes a rotating screw arranged vertically and rotatably connected to the top of the compaction body, and a wheel fixedly arranged on the top of the rotating screw. The rotating screw is threadedly connected to the lifting assembly.

[0009] Furthermore, the lifting assembly includes a lifting frame threadedly connected to a rotating screw, and two connecting blocks respectively arranged on opposite sides of the lifting frame and hinged to opposite sides of the fixed end of the push-pull handle. The connecting blocks and the hinged ends of the push-pull handle maintain a preset vertical gap relative to the lifting frame.

[0010] Furthermore, the compaction device also includes a support frame sleeved around the rotating screw and connected to the compaction body.

[0011] Furthermore, the lifting frame has a vertical clearance opening, and the support frame includes a limiting plate sleeved on the rotating screw and a connecting plate passing through the clearance opening and connected to the compaction body and the limiting plate respectively.

[0012] Furthermore, the traction assembly includes a connecting shaft arranged horizontally on the compaction body, a first crank hinged to a first side of the force-applying end of the push-pull handle and a first end of the connecting shaft, and a second crank hinged to a second side of the force-applying end of the push-pull handle and a second end of the connecting shaft.

[0013] Furthermore, the compaction device also includes a linkage component, which includes a mounting frame mounted on the compaction body, a rolling element rotatably mounted on the mounting frame for the rolling end to roll relative to the road surface, and a linkage component connected to the rolling element and the lifting assembly respectively for driving the rolling end of the rolling element away from or in contact with the road surface as it rises and falls with the lifting assembly.

[0014] Furthermore, the rolling element includes a rocker arm, a sleeve, a rotating shaft, and rollers. The rotating shaft is rotatably mounted on the mounting frame and fixedly connected to the rocker arm and the sleeve respectively. The rollers are mounted on the free end of the rocker arm, and the sleeve is connected to the linkage element.

[0015] Furthermore, the linkage includes a linkage rod arranged vertically and fixedly connected to the lifting assembly, and a sliding rod arranged horizontally on the free end of the linkage rod and slidably connected to the inner cavity of the sleeve plate.

[0016] Furthermore, there are multiple linkage components, which are arranged symmetrically relative to the main body.

[0017] This utility model has the following beneficial effects:

[0018] This utility model discloses a concrete pavement compaction device. The compaction body compacts the concrete pavement to improve its strength, rigidity, stability, and smoothness. During compaction, a rotating component drives a lifting component to move vertically up and down. This, in conjunction with a traction component, controls the tilt angle of the push-pull handle relative to the lifting component, thereby adjusting the height of the force-applying end of the push-pull handle. This adapts to changes in the center of gravity during compaction, ensuring the handle maintains an ergonomic force-applying angle under different construction conditions. This facilitates operation by construction workers, minimizes operator fatigue, and improves construction efficiency. This solution achieves stepless adjustment of the height of the force-applying end of the push-pull handle on the compaction body through the coordinated operation of the rotating, lifting, and traction components. Construction workers can flexibly adjust the height according to changes in the center of gravity or force requirements during construction. The adjusted height remains relatively fixed, maintaining the optimal push-pull posture. Compared to existing technologies, the force-applying angle is unrestricted, operation is simple and easy, construction efficiency is high, and practicality is strong, making it suitable for widespread promotion and application.

[0019] In addition to the objectives, features, and advantages described above, this utility model has other objectives, features, and advantages. The present utility model will now be described in further detail with reference to the figures. Attached Figure Description

[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] like Figure 1 and Figure 2 As shown, the concrete pavement compaction device of this embodiment includes a compaction body 100 for compacting concrete pavement, a rotating component 200 rotatably arranged vertically on the compaction body 100, a lifting component 300 connected to the rotating component 200 for vertically raising and lowering as the rotating component 200 rotates, a push-pull handle 400 hinged to the lifting component 300, and a traction component 500 hinged to the force-applying end of the push-pull handle 400 and the compaction body 100 respectively. The traction component 500 is used to control the tilt angle of the push-pull handle 400 relative to the lifting component 300 to adjust the height of the force-applying end of the push-pull handle 400.

[0029] like Figure 1 and Figure 2 As shown, specifically, the concrete pavement compaction device of this utility model compacts the concrete pavement through the compaction body 100 to improve the strength, rigidity, stability, and flatness of the concrete pavement. During the compaction process, the rotating component 200 drives the lifting component 300 to move vertically up and down, which in turn works with the traction component 500 to control the tilt angle of the push-pull handle 400 relative to the lifting component 300. This adjusts the height of the force-applying end of the push-pull handle 400 to adapt to changes in the center of gravity during compaction, ensuring that the push-pull handle 400 maintains an ergonomic force-applying angle under different construction conditions. This design facilitates force application by construction workers, minimizes operator fatigue, and improves construction efficiency. Through the coordinated operation of the rotating component 200, lifting component 300, and traction component 500, the height of the force-applying end of the push-pull handle 400 on the compaction body 100 is infinitely adjustable. Construction workers can flexibly adjust the height according to changes in the center of gravity or force requirements during construction. The adjusted height remains relatively fixed, maintaining the optimal push-pull posture. Compared to existing technologies, the force application angle is unrestricted, operation is simple and easy, construction efficiency is high, and practicality is strong, making it suitable for widespread promotion and application.

[0030] It should be understood that if the push-pull handle 400 is directly hinged to the compaction body 100, although the height of the force-applying end of the push-pull handle 400 can be adjusted more flexibly, its height cannot be fixed and will change at any time during construction. Therefore, it cannot achieve the best push-pull posture to facilitate construction personnel to apply force to push and pull the compaction body 100 and improve construction efficiency.

[0031] like Figure 1 , Figure 2 and Figure 4 As shown, in this embodiment, the rotating assembly 200 includes a rotating screw 210 arranged vertically and rotatably connected to the top of the compaction body 100, and a rotating wheel 220 fixedly arranged on the top of the rotating screw 210. The rotating screw 210 is threadedly connected to the lifting assembly 300. Specifically, rotating the rotating wheel 220 can drive the rotating screw 210 to rotate. The lifting assembly 300 is threadedly connected to the rotating screw 210 to convert rotation into vertical movement using the threaded transmission principle, thereby driving the lifting assembly 300 to rise and fall vertically. This allows the lifting assembly 300 to cooperate with the traction assembly 500 to control the tilt angle of the force-applying end of the push-pull handle 400 relative to the lifting assembly 300.

[0032] Alternatively, in another embodiment, the rotating assembly 200 includes a rotating handle fixedly disposed on the top of the rotating screw 210.

[0033] In this embodiment, the rotating screw 210 is rotatably connected to the top of the compaction body 100 via a bearing.

[0034] like Figure 1 , Figure 2 and Figure 4 As shown, in this embodiment, the lifting assembly 300 includes a lifting frame 310 threadedly connected to the rotating screw 210, and two connecting blocks 320 respectively arranged on opposite sides of the lifting frame 310 and hinged to opposite sides of the fixed end of the push-pull handle 400. The hinged ends of the connecting blocks 320 and the push-pull handle 400 maintain a preset vertical gap relative to the lifting frame 310. Specifically, the lifting frame 310 is threadedly connected to the rotating screw 210 so that the lifting frame 310 can be vertically raised and lowered when the rotating screw 210 rotates. Then, two connecting blocks 320 respectively arranged on opposite sides of the lifting frame 310 are hinged to opposite sides of the fixed end of the push-pull handle 400, and the hinged ends of the connecting blocks 320 and the push-pull handle 400 maintain a preset vertical gap relative to the lifting frame 310 so that the push-pull handle 400 can rotate relative to the lifting frame 310. This allows it to cooperate with the traction component 500 to control the tilt angle of the push-pull handle 400 relative to the lifting component 300, thereby adjusting the height of the force-applying end of the push-pull handle 400.

[0035] In this embodiment, the push-pull handle 400 is hinged to the connecting block 320 via a pin.

[0036] It should be understood that the preset vertical gap can be adaptively set according to adjustment needs. Generally, the larger the preset vertical gap, the greater the height adjustment range of the force application end of the lifting component 300.

[0037] like Figure 1 , Figure 2 and Figure 4 As shown, in this embodiment, the compaction device further includes a support frame 600 sleeved around the rotating screw 210 and connected to the compaction body 100. Specifically, the support frame 600 provides radial support for the rotating screw 210 to prevent the rotating screw 210 from shifting or swaying due to uneven force or vibration, thereby ensuring the stability and reliability of the lifting assembly 300 during vertical lifting.

[0038] like Figure 1 and Figure 2 As shown, in this embodiment, the lifting frame 310 has a vertical clearance opening, and the support frame 600 includes a limiting plate sleeved on the rotating screw 210 and a connecting plate passing through the clearance opening and connected to the compaction body 100 and the limiting plate respectively. Specifically, the support frame 600 uses the limiting plate to radially limit the rotating screw 210, providing radial support for the rotating screw 210. The connecting plate passes through the clearance opening and is connected to the compaction body 100 and the limiting plate respectively, so as to prevent the lifting frame 310 from rotating circumferentially while providing radial support for the rotating screw 210, and ensure that the rotation of the rotating screw 210 can drive the lifting frame 310 to rise and fall vertically.

[0039] In this embodiment, there are two connecting plates, located on opposite sides of the limiting plate.

[0040] like Figure 1 and Figure 2 As shown, in this embodiment, the traction assembly 500 includes a connecting shaft 510 arranged horizontally on the compaction body 100, a first crank 520 hinged to the first side of the force-applying end of the push-pull handle 400 and the first end of the connecting shaft 510, and a second crank 530 hinged to the second side of the force-applying end of the push-pull handle 400 and the second end of the connecting shaft 510. Specifically, the first crank 520, the second crank 530, the push-pull handle 400, the lifting assembly 300, and the rotating assembly 200 constitute a four-bar linkage, so that when the rotating assembly 200 drives the lifting assembly 300 to rise and fall, and the lifting assembly 300 drives the fixed end of the push-pull handle 400 to rise and fall, the first crank 520 and the second crank 530 move synchronously, converting the vertical movement of the lifting assembly 300 into an angular change of the push-pull handle 400, thereby adjusting the angle of the force-applying end of the push-pull handle 400.

[0041] In this embodiment, the first crank 520 is hinged to the push-pull handle 400 via a pin.

[0042] In this embodiment, the second crank 530 is hinged to the push-pull handle 400 via a pin.

[0043] like Figure 1 In this embodiment, the compaction device further includes a linkage component 700, which is mounted on a mounting frame 710 on the compaction body 100, a rolling element 720 rotatably mounted on the mounting frame 710 for rolling relative to the road surface, and a linkage component 730 connected to the rolling element 720 and the lifting component 300 respectively for moving the rolling end of the rolling element 720 away from or in contact with the road surface as the lifting component moves up and down. Specifically, the linkage 730 drives the rolling element 720 to rotate relative to the mounting frame 710, so that the rolling end of the rolling element 720 is away from or in contact with the road surface. This allows the compaction device to have a "moving mode" and a "compacting mode", and can quickly switch between the two modes. In the moving mode, the lifting component 300 moves upward, which drives the linkage 730 to move upward, and then drives the rolling element 720 to rotate relative to the mounting frame 710. This allows the rolling end of the rolling element 720 to touch the ground and support the compaction body 100, so that it can roll relative to the road surface and be easily dragged. In the compacting mode, the lifting component 300 moves downward, which drives the linkage 730 to move downward, and then drives the rolling element 720 to rotate relative to the mounting frame 710. This allows the rolling end of the rolling element 720 to move away from the road surface, and the compaction body can compact the concrete road surface.

[0044] It should be understood that the rolling end of the rolling element 720 contacting the road surface means that after the rolling end of the rolling element 720 touches the bottom, it supports the compaction body 100 and can roll relative to the road surface, thereby facilitating the movement of the compaction device.

[0045] like Figure 3 As shown, in this embodiment, the rolling element 720 includes a rocker arm 721, a sleeve plate 722, a rotating shaft 723, and a roller 724. The rotating shaft is rotatably mounted on the mounting frame 710 and fixedly connected to the rocker arm 721 and the sleeve plate 722 respectively. The roller 724 is mounted on the free end of the rocker arm 721. The sleeve plate 722 is connected to the linkage element 730. Specifically, when the linkage element 730 drives the sleeve plate 722 to rotate relative to the mounting frame 710, the sleeve plate 722 drives the rocker arm 721 to rotate synchronously through the rotating shaft, so that the roller 724 moves away from or contacts the road surface.

[0046] It should be understood that the swing arm 721, sleeve plate 722 and rotating shaft 723 can be made of high-strength alloy steel or structural steel, with excellent tensile, compressive and bending strength, so that when the compaction device is in the moving mode and the compaction body 100 is supported by the roller 724, it can withstand the dynamic load and impact of the compaction body 100.

[0047] It should be understood that both high-strength alloy steel and high-strength structural steel are materials well known to those skilled in the art.

[0048] like Figure 3 As shown, in this embodiment, the linkage 730 includes a linkage rod 731 arranged vertically and fixedly connected to the lifting assembly 300, and a sliding rod 732 arranged horizontally on the free end of the linkage rod 731 and slidably connected to the inner cavity of the sleeve plate 722. Specifically, the sleeve plate 722 has a waist-shaped groove. When the lifting assembly 300 moves vertically and the linkage rod 731 moves vertically, the sliding rod 732 moves vertically simultaneously and slides within the waist-shaped groove of the sleeve plate 722, causing the sleeve plate 722 to rotate relative to the mounting frame 710. During the mutual linkage process, interference and obstruction between the components are avoided.

[0049] It should be understood that the linkage rod 731 can also limit the rotational freedom of the lifting assembly 300, ensuring that the lifting assembly 300 moves only vertically along the axis of the rotating screw 210, and preventing the push-pull handle 400 from deflecting and becoming uncontrollable.

[0050] It should be understood that the linkage rod 731 and the sliding rod 732 are made of high-strength alloy steel or structural steel, and have excellent tensile, compressive and bending strength, so that when the compaction device is in the moving mode and the compaction body 100 is supported by the roller 724, it can withstand the dynamic load and impact of the compaction body 100.

[0051] like Figure 3 As shown, in this embodiment, multiple linkage components 700 are provided, and the multiple linkage components 700 are symmetrically arranged relative to the compaction body 100. The mounting frame 710, rolling element 720, and linkage element 730 are arranged in a one-to-one correspondence. Specifically, in the moving mode, the multiple linkage components 700 jointly support the compaction body 100 to share the load, so as to avoid the phenomenon of individual components breaking due to excessive load. Moreover, if any group of linkage components 700 fails, the other linkage components 700 can still temporarily maintain the stability of the moving mode.

[0052] In this embodiment, there are four linkage components 700 arranged in a rectangular pattern. The lifting frame 310 is connected to all four linkage components 700 to drive them to move synchronously.

[0053] like Figures 1-4As shown, in one embodiment, the working principle of the compaction device is as follows: the construction worker rotates the rotating wheel 220, driving the rotating screw 210 to rotate, thereby causing the lifting frame 310 to move vertically. This, in turn, drives the fixed end of the push-pull handle 400 to rise and fall synchronously via two connecting blocks 320. Under the pull of the traction component 500, the push-pull handle 400 rotates relative to the connecting blocks 320, controlling the tilt angle of the push-pull handle 400 relative to the lifting frame 310, thus adjusting the height of the force-applying end of the push-pull handle 400. Under the action of the linkage component 700, the roller 724 moves away from or touches the ground as the height of the push-pull handle 400 changes. When the lifting frame 310 moves vertically upward, the push-pull handle 400 tilts downward to reduce the height of the force-applying end of the push-pull handle 400. Simultaneously, the linkage rod 731 moves upward to drive the sliding rod 732 upward, thereby causing the swing rod 721 to retract inward around the mounting frame 710, so that the roller 724 contacts the road surface, the bottom of the compaction body 100 separates from the concrete road surface, and the compaction device enters the moving mode, so that the compaction device can be dragged at a low center of gravity; when the lifting frame 310 moves vertically downward, the push-pull handle 400 tilts upward to increase the height of the force application end of the push-pull handle 400. At the same time, the linkage rod 731 moves downward to drive the sliding rod 732 downward, thereby causing the swing rod 721 to unfold outward around the mounting frame 710, so that the roller 724 moves away from the road surface, the bottom of the compaction body 100 contacts the concrete road surface, and the compaction device enters the compaction mode, so that the concrete road surface can be pushed and compacted at a high center of gravity.

[0054] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0055] 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.
