Description

Technical Field

[0001] This utility model relates to the field of asphalt paving technology, specifically a paving device for high-modulus asphalt on highways. Background Technology

[0002] Asphalt pavement refers to various types of pavement constructed by mixing road asphalt materials into mineral materials. It is the main pavement structure of highways. Asphalt binder improves the ability of paving aggregates to resist damage to the pavement from traffic and natural factors, making the pavement smooth, dust-free, impermeable, and durable. Asphalt pavement is usually laid using paving equipment.

[0003] An investigation revealed that a utility model patent (publication number: CN214168652U) discloses an asphalt paving device for highway construction. A sweeping mechanism is rotatably connected to the inner side of the sweeping housing, a propeller is rotatably connected to the inner side of the feeding chamber, a leveling roller is rotatably connected to the inner side of the paving chamber at its front end, and a pressing roller is rotatably connected to the inner side of the paving chamber at its rear end. This utility model, through the pre-sweeping of the road surface by the sweeping mechanism, can sweep dust, gravel, etc., from the road surface to the roadside, ensuring a tight bond between the asphalt and the road surface. This prevents dust, gravel, etc., from affecting the bond between the asphalt and the road surface, thus avoiding asphalt separation and delamination, which can lead to peeling and water seepage over long-term use. Furthermore, during the paving process, the leveling roller evenly spreads the asphalt, and the pressing roller ensures uniform paving.

[0004] Although the aforementioned patent achieves the flat laying of asphalt, it cannot precisely adjust the asphalt material according to the paving thickness during the asphalt material processing, and it cannot ensure the uniformity of asphalt material distribution. As a result, the uneven distribution of asphalt material during compaction can easily lead to inconsistent compaction density, thereby reducing the service life of the asphalt pavement.

[0005] Therefore, this utility model provides a paving device for high-modulus asphalt on highways to solve the above problems. Utility Model Content

[0017] 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 protection scope of the present utility model.

[0018] like Figure 1-6 As shown, this utility model provides a paving device for high-modulus asphalt on highways, including a frame 1, a sweeping box at the front end of the frame 1, and a feeding assembly 2 inside the end of the frame 1 near the sweeping box; a bulk material assembly 3, which includes a vibrating disc 31, vibratingly installed below the discharge end of the feeding assembly 2; and a leveling assembly 4, located in the middle section inside the frame 1, including a leveling plate 41, which is vertically adjustable inside the frame 1. The upper surface of a support lug 45 is fixedly connected to the lifting end of a cylinder 6. Through the operation of the cylinder 6, the leveling plate 41 is adjusted vertically via the connected support lug 45. The adjustment allows for precise adjustment of the thickness of the asphalt material below. A discharge pipe 42 is integrally formed on the top of the flat plate 41, and a second auger 44 is rotatably connected inside the discharge pipe 42. Support ears 45 are connected to each corner of the flat plate 41. A pressure roller 5 is located inside the end of the frame 1 furthest from the feeding component 2 and is used for vibratory compaction of the asphalt. With the addition of asphalt material by the feeding component 2 and the vibration dispersion by the bulk material component 3, the asphalt material is evenly distributed. Further, with the cooperation of the leveling component 4, the asphalt material undergoes pre-compaction treatment, while the height of the asphalt material is precisely controlled. Finally, the compaction treatment by the pressure roller 5 achieves the laying of the asphalt pavement.

[0019] Furthermore, the feeding assembly 2 includes a feeding pipe 21, one end of which is fixedly connected to a distributing pipe 22, which is fixedly connected inside the frame 1. One end of the distributing pipe 22 is fixedly connected to a first motor 23, and the output end of the first motor 23 is fixedly connected to a first auger 24. The first auger 24 is rotatably disposed inside the distributing pipe 22. Driven by the first motor 23, the first auger 24 can be rotated. When the feeding pipe 21 guides the asphalt material into the distributing pipe 22, the rotation of the first auger 24 drives the asphalt material to move left and right, thereby achieving uniform feeding control of the asphalt material.

[0020] Furthermore, both ends of the vibratory plate 31 are fixedly connected to support plates 32. The bulk material assembly 3 also includes positioning seats 33, which are fixedly connected to the outer wall of the frame 1. A guide shaft 34 is fixedly connected to one side of the positioning seats 33 that is close to each other, and a spring 35 is sleeved on the outside of the guide shaft 34. The ends of the springs 35 that are close to each other abut against the upper and lower sides of the support plate 32. A vibration motor 37 is fixedly connected to the bottom of the vibratory plate 31, and the vibration motor 37 is used for vibration control of the vibratory plate 31. A vibrating rod 36 is fixedly connected to the side of the vibratory plate 31 near the leveling assembly 4 through a bracket. The upper surface of the vibratory plate 31 is inclined. The upper and lower sides of the support plate 32 are connected to the frame 1 through corrugated covers. The asphalt material is discharged from the distribution pipe 22 and falls onto the vibratory plate 31. At this time, the vibratory plate 31, under the vibration control of the vibration motor 37, makes the asphalt material fully dispersed. At the same time, under the vibration of the vibrating rod 36, the asphalt material on the base surface is evenly distributed horizontally, avoiding unevenness on the surface of the asphalt material.

[0021] Furthermore, a second motor 43 is fixedly connected to the center of the upper surface of the discharge pipe 42. Two sets of second augers 44 are symmetrically arranged, and the ends of the two sets of second augers 44 that are close to each other are connected to the output end of a gear commutator. The output end of the second motor 43 is connected to the drive end of the gear commutator. The second motor 43 drives the second augers 44 to rotate, thereby discharging the excess asphalt material collected by the plate 41, ensuring the consistency of the asphalt thickness. At the same time, conveying equipment can be connected to both ends of the discharge pipe 42 to mix the collected asphalt material for secondary use.

[0022] Furthermore, a support shaft 51 is connected to the center of the pressure roller 5, and bearing seats 52 are rotatably connected to both ends of the support shaft 51. The lifting end of the cylinder 6 is fixedly connected to the upper surface of the bearing seats 52 and the support ears 45, and the housing of the cylinder 6 is fixedly connected to the outer wall of the frame 1. The frame 1 is provided with guide grooves corresponding to the bearing seats 52 and the support ears 45. By connecting a drive device to one end of the support shaft 51 to drive the pressure roller 5 to move on its own, the compaction of the pre-tightened asphalt pavement can be achieved under the self-movement of the pressure roller 5.

[0023] Working principle: First, the device is connected to external equipment, and the feeding pipe 21 is connected to the external asphalt supply pipe. When the device moves on its own, the feeding pipe 21 feeds asphalt. Under the uniform dispersion of the material by the distribution pipe 22, the asphalt falls above the vibrating plate 31. Then, under the vibration of the vibrating plate 31 and the vibrating rod 36, the falling asphalt material is fully dispersed. The uniformly dispersed asphalt material is pre-compacted by the flat plate 41. At the same time, the excess asphalt is collected into the discharge pipe 42. The collected asphalt material is discharged by the rotation of the second auger 44 inside the pipe. Finally, the pre-tightened asphalt pavement is compacted by the pressure roller 5.

[0024] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
