Description

Technical Field

[0001] This invention belongs to the field of construction machinery technology, specifically relating to an asphalt paving device for road and bridge construction. Background Technology

[0002] The smoothness of asphalt pavement involves a wide range of aspects and is influenced by many factors. The key to asphalt concrete pavement construction is the rational allocation of personnel, materials, and equipment. Effective dynamic management of the entire construction process is required, along with strict control over various tests and inspections. The surface structure of uncompacted mixture should be uniform and smooth in both longitudinal and transverse directions, free from tearing, small waves, local roughness, and grooves.

[0003] A crucial factor in ensuring the smoothness of asphalt pavement is the paving effect of the asphalt raw materials. Currently, a large number of asphalt paving equipment imported into the market have achieved good paving results when dealing with straight roads. However, when dealing with curved roadbeds, the turning radius of the construction vehicles can cause an angle difference between the paving equipment and the road surface. This results in unequal sweeping speeds between the inner and outer diameter sections, leading to a difference in the amount of asphalt added to the inner and outer sections. Consequently, the outer diameter section requires manual replenishment of excess filler, increasing the intensity of manual labor. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this invention is to provide an asphalt paving device for road and bridge construction to solve the problems mentioned in the background.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

Detailed Implementation

[0024] To more clearly illustrate the structural features and effects of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] Please see Figures 1-5An embodiment of the present invention provides an asphalt paving device for road and bridge construction, comprising a frame component 1, which includes a main frame 101, a secondary frame 102, a support 103, and a guide plate 105. The secondary frame 102 is rotatably mounted on one end of the main frame 101, and the support 103 is fixedly mounted on the end of the secondary frame 102. The guide plate 105 is arranged on the support 103. A material conveying assembly 2 includes a main plate 201, a secondary plate 202, a guide column 203, a rotating shaft 207, and a tipping plate 208. The main plate 201 and the secondary plate 202 are fixedly connected and spaced apart. A guide column 203 is provided at one end of the main plate 201. The guide post 203 is slidably connected to the guide plate 105. A rotating shaft 207 is also rotatably provided on one side of the bottom of the main plate 201 and the sub-plate 202. A plurality of material turning plates 208 are arranged circumferentially on the rotating shaft 207. The drive assembly 3 includes a first driver 301 and a second driver 304. The first driver 301 and the second driver 304 are both located at one end of the main plate 201 and are used to control the input and output of materials. The feeding assembly 4 is fixedly located on one side of the main frame 101 and is used to feed the asphalt to be paved between the main plate 201 and the sub-plate 202.

[0026] In practical application, when the equipment is used for asphalt paving, the main frame 101 is fixedly connected to the work vehicle and positioned at the front of the vehicle. When the work vehicle is paving asphalt on a curve, the rotation angle of the auxiliary frame 102, which is mounted on the main frame 101, is controlled. This ensures that the construction plane of the auxiliary frame 102 and its support 103 remains perpendicular to the curved road surface, and the paved surface moves along the tangent of the curve, thus achieving full filling of the asphalt material. Furthermore, during the movement of the work vehicle, the guide plate 105 can be driven to slide on the guide post 203, thereby controlling the horizontal distance between the main frame 101 and the main frame 201. The sliding mechanism adjusts the horizontal movement trajectory of the main board 201. The discharge position of the material conveying component 2 can be adjusted according to different road conditions and construction needs. The asphalt material to be distributed is fed into the space between the main board 201 and the sub-board 202 via the feeding component 4 and then falls into the storage space at the bottom. When the rotating shaft 207 rotates under the driving force, the overturning plate 208 can quantitatively pour the stored asphalt material onto the ground, filling the foundation surface to achieve stable asphalt output. Simultaneously, it ensures that the area swept by each part of the material conveying component 2 is similar per unit time during the movement of the construction vehicle on curves, ensuring uniform distribution of asphalt material on the road surface and preventing uneven distribution on curves.

[0027] Please see Figure 2In a preferred embodiment of the present invention, the frame component 1 further includes a rotating gear shaft 104, which is disposed at one end of the sub-frame 102 and is used to control the rotation angle of the sub-frame 102.

[0028] In practical application, the rotating gear shaft 104 is located at one end of the sub-frame 102. An external drive source can drive the gear shaft to mesh and drive the sub-frame 102 to rotate at a certain angle. Thus, the rotation angle of the material conveying component 2 can be adaptively adjusted according to the rotation radius of the construction vehicle, so that the material conveying component 2 always delivers asphalt raw materials along the road subgrade section.

[0029] Please see Figure 3 In a preferred embodiment of the present invention, the material conveying assembly 2 further includes a drive screw 204, which is disposed parallel to the guide post 203 and rotatably mounted on one end of the main board 201, and is movably connected to the guide plate 105, for controlling the directional sliding of the guide plate 105.

[0030] In practical application, the drive screw 204 is rotatably mounted on one end of the main board 201 and is movably connected to the guide plate 105 at one end of the sub-frame 102. During the rotation of the drive screw 204, the other end of the guide plate 105 is limited and slidably mounted on the guide post 203, thereby enabling the main board 201 to slide directionally on one side of the main frame 101 to adjust the sliding distance of the main board 201 relative to the main frame 101.

[0031] Please see Figure 3 In a preferred embodiment of this invention, the material conveying assembly 2 further includes a scraper 205, an arc-shaped cavity 206, and a vibrating plate 209. The scraper 205 is fixedly disposed at one end of the main plate 201 and is located near the ground. The arc-shaped cavity 206 is disposed at the bottom of the auxiliary plate 202 and is matched with the turning plate 208 to cooperate with the turning plate 208 to quantitatively output the asphalt to be paved. The vibrating plate 209 is elastically limited and slidably assembled between the main plate 201 and the auxiliary plate 202.

[0032] In practical application, the scraper 205 is fixedly installed at one end of the main board 201. This allows the asphalt material released from one side of the tipping plate 208 to be flattened and spread when it falls to the ground, preventing excessive accumulation of asphalt material at the same point and ensuring uniform spreading of the asphalt material. The arc-shaped groove of the arc cavity 206 is matched with the tipping plate 208, allowing the material in the cavities of the main board 201 and the secondary plate 202 to fall between the two tipping plates 208 during the accumulation process. When the tipping plate 208 rotates to one side of the arc cavity 206, it can rotate the quantitatively stored asphalt material between the two tipping plates 208 to the bottom of the arc cavity 206 for release, thereby realizing quantitative output of the material.

[0033] Please see Figure 4 In a preferred embodiment of the present invention, the drive assembly 3 further includes a first bevel gear 302, a second bevel gear 303, a drive wheel 305, a driven wheel 306, a cam 307, a bevel gear shaft 308, and a third bevel gear 309. The first bevel gear 302 is fixedly mounted on the first driver 301. One end of the second bevel gear 303 is fixedly connected to the drive screw 204, and the other end is meshed with the first bevel gear 302. The drive wheel 305 is fixedly mounted on the second driver 304. One end of the driven wheel 306 is linked to the drive wheel 305, and the other end is fixedly connected to the cam 307. The cam 307 movably abuts against the vibrating plate 209. One end of the bevel gear shaft 308 is linked to the drive wheel 305, and the other end is meshed with the third bevel gear 309. The end of the third bevel gear 309 is fixedly mounted on the rotating shaft 207.

[0034] In practical application, in this embodiment, when the first driver 301 is in the start-up state, its first bevel gear 302 can mesh with and drive the second bevel gear 303 to rotate. Since one end of the second bevel gear 303 is fixedly connected to the drive screw 204, it can drive the drive screw 204 to rotate synchronously, thereby driving the relative sliding between the motherboard 201 and the main frame 101. When the second driver 304 is in the start-up state, since one end of its drive wheel 305 is linked with the driven wheel 306 and the bevel gear shaft 308, the driven wheel 306 can synchronously drive the rotation of the cam 307 when it rotates. The cam 307, since one end of its drive wheel 305 is linked with the driven wheel 306 and the bevel gear shaft 308, can synchronously drive the rotation of the cam 307. The vibrating plate 209 rotates and abuts against the main plate 201, thus driving the vibrating plate 209 to elastically reciprocate between the main plate 201 and the secondary plate 202. This allows the asphalt input through the feeding assembly 4 between the main plate 201 and the secondary plate 202 to be uniformly vibrated, so that the asphalt material is evenly filled on the surface of the vibrating plate 209. Under the action of vibration, the asphalt material passes through the sieve holes on the vibrating plate 209 and falls into the cavity between the main plate 201 and the secondary plate 202 for storage. During the rotation of the bevel gear shaft 308, it can mesh with and drive the rotation of the third bevel gear 309, so that the rotating shaft 207 fixedly connected to the third bevel gear 309 rotates synchronously to achieve continuous feeding of asphalt material.

[0035] Please see Figure 2 In a preferred embodiment of the present invention, the feeding assembly 4 includes a feeding pipe 401, a guide plate 402, a guide disc 403, and a discharge plate 404. The feeding pipe 401 is fixedly disposed at one end of the main frame 101 and communicates with the output end of the asphalt raw material. The guide plate 402 is fixedly disposed on the auxiliary frame 102. The guide disc 403 is disposed on the side of the guide plate 402 near the feeding pipe 401. The guide disc 403 is disposed facing the discharge end of the feeding pipe 401. The discharge plate 404 is disposed at the other end of the guide plate 402. The discharge plate 404 is disposed between the main plate 201 and the auxiliary plate 202 and is spaced apart from the main plate 201 and the auxiliary plate 202. The discharge end of the feeding pipe 401 is coaxially disposed with the guide disc 403.

[0036] In practical application, the feed pipe 401 can be used to connect the asphalt material conveying mechanism and output the asphalt material along the feed pipe 401 to the guide plate 403, so that the asphalt material rolls down the inclined surface of the guide plate 402 between the main plate 201 and the auxiliary plate 202. Since the discharge end of the feed pipe 401 is coaxially arranged with the guide plate 403, when the main plate 201 rotates with the auxiliary frame 102, the receiving center of the guide plate 403 is always aligned with the opening of the feed pipe 401, thereby ensuring the continuous output of asphalt material. Furthermore, when the position of the main plate 201 on one side of the main frame 101 is adjusted, since the discharge plate 404 is spaced apart from the main plate 201 and arranged parallel to the main plate 201, the feeding of material is not affected by the position movement of the main plate 201.

[0037] The above embodiments of the present invention provide an asphalt paving device for road and bridge construction. By providing a rotatable sub-frame 102 on one side of the main frame 101 and slidingly mounting a material conveying component 2 on the sub-frame 102, the device can rotate the material conveying component 2 to a position tangent to the curved roadbed during the turning of the construction vehicle, ensuring that the asphalt material on the roadbed can be evenly distributed and avoiding uneven distribution of asphalt material at curves.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
