Description

Technical Field

[0001] The invention relates to the technical field of road construction, and in particular to road paving equipment with a vibrating function. Background Art

[0002] During cement road construction, after pouring concrete into the prepared road formwork, bubbles must be removed and tamping and compaction must be performed to ensure a dense bond between the concrete and eliminate honeycombed surfaces. This improves the strength of the concrete and ensures the quality of the concrete components. Currently, after pouring the cement, the concrete must be evenly spread on the formwork manually. A handheld vibrator is then used to vibrate the concrete, and after the vibration is completed, the road surface is flattened using a push plate. This process is time-consuming and labor-intensive. For example, Chinese Patent Publication No. CN218540284U discloses a concrete road surface paving and leveling vibration device. The device, through the provision of a vibrating mechanism, first lays guide rails on both sides of the road surface, and places the vibrating structure on top. A first motor is provided to move the tamping motor forward, and a second motor is provided to move the tamping motor left and right, thereby improving the vibration effect. Furthermore, a cylinder and a push plate are used to push the road surface back and forth, ensuring a flattening effect. The device has a high degree of mechanization, reduces labor costs, and improves work efficiency. However, the device still has the following problems:

[0003] 1. The device does not spread the concrete on the road surface evenly before vibration, resulting in uneven distribution of cement on the road surface, affecting the subsequent vibration and compaction work. It still requires artificial tidal flat cement work before work, which is time-consuming and labor-intensive.

[0004] 2. During the cement compaction process, a push plate or roller is usually required to roll back and forth on the cement surface to improve the cement compaction effect. However, the vibration structure in this device is fixed. During the back-and-forth movement, the vibration structure moves in the cement slurry, which is easy to destroy the road surface flattened last time, which is not conducive to the reciprocating cement compaction work.

[0005] 3. The vibrating structure of the device is fixed, and it is not easy to set the length of the device extending into the cement according to the actual depth of the cement slurry, resulting in poor vibration effect. Summary of the Invention

[0024] Example 1:

[0025] Reference Figures 1 to 3 The present invention provides a road paving device with a vibrating function, including a frame 1, a lifting frame 2, a swing frame 3 and a track 11. The frame 1 is movably mounted on the track 11. The frame 1 is provided with a driving wheel 12 driven by a motor. The driving wheel 12 is used to drive the frame 1 to move on the track 11. The lifting frame 2 is movably mounted on the frame 1. The frame 1 is provided with a lifting mechanism 13 for driving the lifting frame 2 to rise and fall. The lifting frame 2 is provided with a flattening mechanism 4, a pressure roller assembly 5 and a plurality of vibrating assemblies 6.

[0026] The lifting frame 2 is driven to rise and fall by the lifting mechanism 13 to drive the pressure roller assembly 5 to be close to the cement surface. The flipping mechanism 7 first drives the swing frame 3 to drive the vibrating rod 63 to be inserted into the cement and cooperates with the driving wheel 12 to drive the entire frame 1 forward to perform the vibration work. The leveling mechanism 4 cooperates with the movement of the frame 1 to evenly spread the cement on the road surface. Among them, the adjustment mechanism 9 can adjust the distance between the moving frame and the mounting frame 31 to adjust the depth of the vibrating rod 63 inserted into the cement to be suitable for the vibration work of cement of different thicknesses; after the vibration work is completed, the swing frame 3 is driven to rotate by the flipping mechanism 7, and the swing frame 3 moves the vibrating rod 63 out of the cement and drives the compacting mechanism 8 to press it on the cement surface. The compacting mechanism 8 cooperates with the reciprocating movement of the pressure roller assembly 5 and the frame 1 to compact and level the road surface. It has the functions of automatically spreading cement, vibrating and compacting the road surface, reducing labor costs while improving the efficiency of road trimming.

[0027] Specifically, the flattening mechanism 4 includes a driving motor 41 and a rotating rod 42 . The driving motor 41 is in transmission connection with the rotating rod 42 and can drive the rotating rod 42 to rotate. A first spiral blade 421 and a second spiral blade 422 with opposite rotation directions are provided on the outer periphery of the rotating rod 42 .

[0028] The rotating rod 42 is driven to rotate by the driving motor 41. During the rotation of the rotating rod 42, the first threaded blades and the second threaded blades on the rotating rod 42 spread the cement they contact from the middle of the road to both sides, so that the cement can be spread more evenly on the road surface, making the cement thickness more uniform in various parts of the road.

[0029] Example 2:

[0030] Reference Figures 1 to 3 In combination with the technical solution of Example 1, in this embodiment, the flipping mechanism 7 is composed of a plurality of driving cylinders, the piston rods of the driving cylinders being hingedly mounted on the swing frame 3, and the cylinder bodies of the driving cylinders being hingedly mounted on the lifting frame 2. The swing frame 3 is flipped by the synchronous extension and retraction of the plurality of driving cylinders.

[0031] Specifically, the mounting frame 31 is provided with a slide rod 32 for the movable installation of the swing frame 3. The adjustment mechanism 9 includes a drive motor 91 and a screw rod 92. The drive motor 91 is transmission-connected to the screw rod 92 and can drive the screw rod 92 to rotate. The drive motor 91 is set on the mounting frame 31, and a screw hole that cooperates with the screw rod 92 is set on the movable frame.

[0032] The screw 92 is driven to rotate by the driving motor 91, and the screw 92 cooperates with the screw hole on the movable frame to drive the movable frame to move along the slide rod 32, that is, the distance between the movable frame and the mounting frame 31 is adjusted, thereby adjusting the depth of the vibrating rod 63 inserted into the cement.

[0033] Example 3:

[0034] Reference Figures 1 to 3 Combining the technical solutions of Example 1 and Example 2, in this embodiment, the compacting mechanism 8 includes a pressing plate 81, a vibration motor 82 and a traction assembly 83. The vibration motor 82 is arranged on the pressing plate 81, and one side of the pressing plate 81 is rotatably mounted on the swing frame 3. The traction assembly 83 is connected to the other side of the pressing plate 81 and can adjust the flipping angle of the pressing plate 81.

[0035] Specifically, the traction assembly 83 includes a hoist 831 and a traction rope 832 . The traction rope 832 is wound around the hoist 831 , and the free end of the traction rope 832 is connected to the pressure plate 81 .

[0036] After the vibration work is completed, when the cement compaction work needs to be carried out, the turning mechanism 7 drives the swing frame 3 to rotate, and the swing frame 3 moves the vibrating rod 63 out of the cement and drives the pressing plate 81 close to the cement surface until the pressing plate 81 is pressed tightly on the cement surface. During the process of the pressing plate 81 approaching the cement surface, the winch 831 cooperates with the traction rope 832 to pull one side of the pressing plate 81 so that the pressing plate 81 is slightly tilted relative to the cement surface (in a state of left lower and right higher). The left side of the pressing plate 81 first contacts the cement surface, and the swing frame 3 continues to drive the pressing plate 81 to approach the cement surface. The traction rope 83 2 gradually relaxes, and the right side of the pressing plate 81 gradually approaches the cement surface until the right side of the pressing plate 81 is in close contact with the cement surface, and the swing frame 3 stops flipping. At this time, the entire pressing plate 81 is in close contact with the cement surface under the action of its own weight. The pressing plate 81 cooperates with the vibration process of the vibration motor 82 and the movement process of the frame 1 to perform vibration compaction on the cement. The setting of this structure is convenient for adjusting the flip angle of the pressing plate 81 in conjunction with the lifting process of the lifting frame 2 and the swing process of the swing frame 3, so that the pressing plate 81 can adaptively fit the cement surface, thereby improving its vibration compaction effect on the cement.

[0037] Specifically, the two sides of the pressing plate 81 are upwardly tilted arc-shaped flange structures. By arranging the arc-shaped flange structures on both sides of the pressing plate 81, the pressing plate 81 is not likely to scrape the cement surface and cause road surface defects during the movement of the random frame 1.

[0038] Specifically, the pressure roller assembly 5 includes a front roller 51 and a rear roller 52 , and both the front roller 51 and the rear roller 52 are rotatably mounted on the lifting frame 2 .

[0039] Specifically, the lifting mechanism 13 is a hydraulic cylinder, which is in transmission connection with the lifting frame 2 and can drive the lifting frame 2 to move up and down relative to the frame 1 .

[0040] The above are only preferred embodiments of the present invention and are not intended to limit the present invention in any form. Any person skilled in the art can, without departing from the scope of the technical solution of the present invention, use the above technical content to make many possible changes and modifications to the technical solution of the present invention, or modify it into an equivalent embodiment with equivalent changes. Therefore, any changes, modifications, equivalent changes and modifications made to the above embodiments based on the technology of the present invention without departing from the content of the technical solution of the present invention shall fall within the scope of protection of the present technical solution.
