Description

Technical Field

[0001] This utility model relates to the field of concrete construction equipment, and in particular to an auxiliary device for laying and compacting asphalt concrete with vibration function. Background Technology

[0002] Asphalt concrete is a commonly used road construction material. It is made by mixing aggregates such as crushed stone, stone chips, and sand with mineral powder in a certain proportion, using asphalt as a binder. It has good adhesion, impermeability and fatigue resistance, can adapt to thermal expansion and contraction caused by temperature changes, is easy to construct and has a high degree of flatness after molding. It is widely used in the surface paving of infrastructure such as highways, urban roads, and airport runways.

[0003] In asphalt concrete paving and compaction operations, existing auxiliary devices often lack effective gravity inertia restraint structures. When working on downhill sections, they are prone to sliding due to their own weight and the gravity component of the slope. Since the device itself has a certain weight, the inertia generated when going downhill will cause the sliding speed to gradually increase. It is difficult to counteract this inertial force by relying solely on manual pulling. This not only increases the physical burden on the operators but also causes the device to collide with surrounding structures or personnel, thereby causing safety accidents and affecting construction safety and work efficiency. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an auxiliary device for asphalt concrete paving and compaction with vibration function, which aims to solve the problem that "the existing technology lacks a gravity inertia constraint structure, which will increase the burden on operators and affect safety and efficiency".

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an auxiliary device for laying and compacting asphalt concrete with vibration function, comprising a flat plate, a first rotating wheel frame fixedly connected to the lower surface of the flat plate, a first roller rotatably connected to the inner wall of the first rotating wheel frame, a first pulley provided at the left end of the rotating shaft of the first roller, a rotating wheel provided at the right end of the rotating shaft of the first roller, and an adjustment component provided at the right end of the first rotating wheel frame. The adjustment assembly includes a limiting block, which is fixedly connected to the right end of the first rotating wheel frame. The rotating wheel is rotatably connected to the inner wall of the limiting block. A first locking block is engaged with the inner wall of the rotating wheel. A second locking block is engaged with both the upper and lower ends of the first locking block. A double-ended threaded rod is threadedly connected to the inner wall of the second locking block. Limiting rings are fixedly connected to the outer wall of the double-ended threaded rod near the upper and lower outer walls of the limiting block.

[0006] As a further description of the above technical solution: The double-ended threaded rod is rotatably connected to the inner wall of the limiting block, and the second locking block is slidably connected to the inner wall of the limiting block.

[0007] As a further description of the above technical solution: A mounting plate is connected to the rear end of the first rotating wheel frame, and a servo motor is mounted on the rear end of the mounting plate. A second pulley is provided at the left end of the output shaft of the servo motor. The second pulley is connected to the output shaft of the servo motor via a belt drive, and the belt drive is connected to the inner wall of the first pulley.

[0008] As a further description of the above technical solution: A push handle is installed on the upper surface of the plate.

[0009] As a further description of the above technical solution: A damping buffer mechanism is installed on the lower surface of the plate. A second rotating wheel frame is fixedly connected to the lower surface of the damping buffer mechanism. A vibration motor is installed on the upper surface of the second rotating wheel frame. A second roller is rotatably connected to the inner wall of the second rotating wheel frame.

[0010] As a further description of the above technical solution: The first card block is set as an arc-shaped structure with rounded corners at both the top and bottom. The end of the second card block closest to the center of the first card block is set as an arc-shaped structure.

[0011] As a further description of the above technical solution: The mounting plate is configured with an L-shaped structure.

[0012] This utility model has the following beneficial effects: 1. In this utility model, by means of the adjustment component set at the right end of the first rotating wheel frame, when going downhill, the operator can twist the double-ended threaded rod to drive the second locking block to move towards the center of the limiting block. The second locking block pushes the first locking block to squeeze the rotating wheel to the left and right sides through the squeezing action. In this way, the rotating wheel can be braked and buffered by friction, allowing the whole device to glide slowly. This not only reduces the physical burden on the operator, but also improves construction safety and work efficiency.

[0013] 2. In this utility model, when construction needs to be paused, the operator needs to twist the double-headed threaded rod through the adjustment component set at the right end of the first rotating wheel frame, which drives the second locking block to squeeze the first locking block, so that the first locking block is tightly attached to the rotating wheel, thereby locking the rotating wheel and improving the practicality of the overall device.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model. Reference Figure 1 - Figure 2 This utility model provides an embodiment of an asphalt concrete paving and compaction auxiliary device with vibration function, including a plate 1. The plate 1 provides a stable installation platform for the entire device, ensuring the fixed position and coordinated operation of each component. A first rotating wheel frame 3 is fixedly connected to the lower surface of the plate 1. The first rotating wheel frame 3 is used to rotatably support a first roller 4, ensuring that the first roller 4 can rotate around its own axis. The first roller 4 is rotatably connected to the inner wall of the first rotating wheel frame 3. The first roller 4 is used to initially pave and compact the concrete by its own rolling, improving the smoothness and density of the road surface. A first pulley 5 is provided at the left end of the rotating shaft of the first roller 4. The first pulley 5 is used to transmit the rotational power of the servo motor 7 to the first roller 4, realizing power transmission. A rotating wheel 14 is provided at the right end of the rotating shaft of the first roller 4. The rotating wheel 14 is used to achieve sliding buffering and locking of the device through contact and friction with a first locking block 22. An adjustment component 2 is provided at the right end of the first rotating wheel frame 3. Reference Figure 1 - Figure 2The adjusting component 2 is used to achieve sliding buffering and locking of the entire device through the contact friction of the first locking block 22. The adjusting component 2 includes a limiting block 21, which provides a sliding track for the second locking block 23, restricting the movement direction of the second locking block 23, and at the same time playing an auxiliary limiting role for the rotating wheel 14. The limiting block 21 is fixedly connected to the right end of the first rotating wheel frame 3. The rotating wheel 14 is rotatably connected to the inner wall of the limiting block 21. The inner wall of the rotating wheel 14 is engaged with the first locking block 22. The first locking block 22 is used to achieve braking through contact friction with the inner wall of the rotating wheel 14. The upper and lower ends of the first locking block 22 are both engaged with the second locking block 22. 3. The second locking block 23 is used to push the first locking block 22 outward by squeezing, so that the first locking block 22 can achieve braking by contacting and rubbing against the inner wall of the rotating wheel 14. The inner wall of the second locking block 23 is threaded with a double-ended threaded rod 24. The double-ended threaded rod 24 is used to drive the two second locking blocks 23 to move synchronously towards the center or sides of the limiting block 21 by twisting the threaded rod. The outer wall of the double-ended threaded rod 24 is fixedly connected to the upper and lower ends of the outer wall near the limiting block 21. The limiting ring 25 is used to restrict the axial movement of the double-ended threaded rod 24 in the limiting block 21 to prevent the threaded rod from shifting position during rotation.

[0017] Reference Figure 3 - Figure 4 The double-ended threaded rod 24 is rotatably connected to the inner wall of the limiting block 21, and the second locking block 23 is slidably connected to the inner wall of the limiting block 21. The rear end of the first rotating wheel frame 3 is connected to the mounting plate 8, which provides a mounting platform for the servo motor 7. The servo motor 7 is mounted at the rear end of the mounting plate 8. The servo motor 7 transmits its rotational power to the first roller 4 through the belt 6 and the first pulley 5 to achieve power transmission. The left end of the output shaft of the servo motor 7 is provided with a second pulley 15, which transmits the rotational power of the servo motor 7 to the first roller 4 to achieve power transmission. The second pulley 15 and the output shaft of the servo motor 7 are connected by the belt 6. The belt 6 transmits the rotational power of the servo motor 7 to the first roller 4 to achieve power transmission. The belt 6 is connected to the inner wall of the first pulley 5. A push handle 12 is mounted on the upper surface of the plate 1. The push handle 12 is used to facilitate the operator to push the entire device to work.

[0018] Reference Figures 5-6A damping buffer mechanism 10 is installed on the lower surface of the plate 1. The damping buffer mechanism 10 is used to buffer the vibration generated by the vibration and avoid the vibration from affecting the overall device. The damping buffer mechanism 10 is existing technology and can buffer the vibration generated by the vibration. Since it is existing technology and can be implemented by those skilled in the art, it will not be described in detail here. A second rotating wheel frame 9 is fixedly connected to the lower surface of the damping buffer mechanism 10. The second rotating wheel frame 9 is used to rotatably support the second roller 11 and ensure that the second roller 11 rotates around its own axis. A vibration motor 13 is installed on the upper surface of the second rotating wheel frame 9. The motor 13 is used to transmit the vibration force generated by itself to the second roller 11. The second roller 11 vibrates the concrete during rotation to enhance the density of the concrete. The inner wall of the second rotating wheel frame 9 is rotatably connected to the second roller 11. The second roller 11 is used to receive the vibration force transmitted by the vibrating motor 13. When vibrating the asphalt concrete, it further enhances the internal density of the concrete. The first clamping block 22 is set as an arc-shaped structure and both the upper and lower ends are set as rounded corner structures. The end of the second clamping block 23 near the center of the first clamping block 22 is set as an arc-shaped structure. The mounting plate 8 is set as an L-shaped structure.

[0019] Working principle: When preparing for work, the vibration motor 13 on the second rotating wheel frame 9 is started. The vibration force generated by the vibration motor 13 is transmitted to the second roller 11. During the rotation of the second roller 11, the asphalt concrete is vibrated to enhance the density of the concrete. At the same time, the damping buffer mechanism 10 on the lower surface of the plate 1 can buffer the vibration generated by the vibration, avoid the vibration from causing excessive impact on other parts of the device, and ensure the stable operation of the device. The servo motor 7 is started. The second pulley 15 set at the left end of its output shaft drives the first pulley 5 at the left end of the first roller 4 rotating shaft to rotate through the belt 6, thereby causing the first roller 4 to rotate on the inner wall of the first rotating wheel frame 3. At the same time, the rotating wheel 14 rotates synchronously with the rotating shaft of the first roller 4. The operator pushes the plate 1 with the push handle 12 to move the entire device. The first roller 4 initially lays and compacts the asphalt concrete.

[0020] When working downhill, the operator twists the double-threaded rod 24 in the adjustment component 2. Because the second locking block 23 is threadedly connected to the double-threaded rod 24 and slidably connected to the inner wall of the limiting block 21, the rotation of the double-threaded rod 24 drives the two second locking blocks 23 to move towards the center of the limiting block 21. The second locking blocks 23 push the first locking block 22 to move outward to the left and right ends through the squeezing action, so that the first locking block 22 is tightly attached to the inner wall of the rotating wheel 14. The friction force forms a braking buffer on the rotating wheel 14, so that the device can slide slowly.

[0021] When construction needs to be paused, the operator twists the double-ended threaded rod 24, causing the second locking block 23 to further press the first locking block 22, so that the first locking block 22 locks the rotating wheel 14, restricting the rotation of the rotating wheel 14, thereby locking the entire device and preventing the device from sliding accidentally.

[0022] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
