Description

Technical Field

[0001] This utility model relates to the technical field of road construction, and in particular to a road construction roller pressing device. Background Technology

[0002] Asphalt pavement refers to various types of pavement constructed by incorporating road asphalt materials into mineral materials. Asphalt binders improve the ability of paving aggregates to resist damage to the pavement from traffic and natural factors, resulting in a smooth, dust-free, impermeable, and durable pavement.

[0003] In asphalt paving, the roller needs to complete three passes of compaction before the asphalt temperature drops to 90℃ to improve the density of asphalt particles. During the rolling process, some asphalt particles may adhere to the surface of the roller. If not cleaned in time, this will affect the rolling effect on the road surface. Currently, scrapers are usually used to remove these particles from the roller surface. However, because asphalt has a certain viscosity, the scraped asphalt particles will adhere to the contact surface between the scraper and the roller. As the asphalt particles accumulate, the scraper's removal effect on the roller surface becomes poor, and the particles will re-adhere to the roller surface, thus affecting the rolling effect on the road surface.

[0005] Therefore, one objective of this utility model is to provide a road construction roller pressing device that can effectively peel off asphalt particles from the surface of the roller and promptly adsorb them into the collection box, thereby improving the cleaning effect of the roller surface and improving the quality of road construction.

A mounting plate is provided on the bracket, and the adsorption assembly is disposed between the two mounting plates and communicates with the cylinder assemblies.

[0007] The road construction roller pressing device of this invention can effectively peel off asphalt particles from the surface of the roller and promptly adsorb them into the collection box, thereby improving the cleaning effect of the roller surface and improving the quality of road construction.

[0019] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0020] The road construction roller pressing device of this utility model is described below with reference to the accompanying drawings.

[0021] like Figures 1 to 3 As shown, the road construction roller pressing device of this utility model embodiment may include a support plate 1, a pressing roller 2, a cleaning component 3, two transmission components 4, two cylinder components 5, and an adsorption component 6.

[0022] The support plate 1 is rotatably connected to the support shaft 7, and the pressure roller 2 is set on the support shaft 7; the support plate 1 is provided with a bracket 8, and the cleaning component 3 is connected to the bracket 8.

[0023] It should be noted that the support plate 1 is a U-shaped plate to support the pressure roller 2, and the support plate 1 is connected to the drive trolley to drive the pressure roller 2 to roll on the construction road surface.

[0024] Furthermore, the cleaning component 3 can scrape off the asphalt particles attached to the surface of the roller 2, thereby improving the effect of road roller compaction.

[0025] Two transmission components 4 are symmetrically arranged on both sides of the support plate 1, and the transmission components 4 are connected to the support shaft 7; two cylinder components 5 are symmetrically arranged on the side wall of the support plate 1, and the two cylinder components 5 are respectively connected to the corresponding transmission components 4; the bracket 8 is provided with a mounting plate 9, the adsorption component 6 is arranged between the two mounting plates 9, and the adsorption component 6 is connected to the cylinder component 5.

[0026] It should be noted that when the support shaft 7 rotates with the pressure roller 2, with the cooperation of the transmission component 4, it can drive the piston 52 of the cylinder component 5 to move back and forth, and adsorb the asphalt particles on the cleaning component 3 through the adsorption component 6, so as to remove the asphalt particles on the cleaning component 3 in a timely manner.

[0027] In one embodiment of this utility model, such as Figure 1 and Figure 2 As shown, the cleaning assembly 3 includes two first connecting shafts 31, a cleaning groove 32, and multiple springs 33. The two first connecting shafts 31 are respectively disposed on the opposite inner walls of the bracket 8; the cleaning groove 32 is disposed between the two first connecting shafts 31, and one end face of the cleaning groove 32 is in contact with the outer wall of the pressure roller 2; the multiple springs 33 are respectively disposed on the bracket 8 and connected to the outer wall of the cleaning groove 32.

[0028] It should be noted that, see Figure 2 The cross-section of the cleaning groove 32 is triangular, and the side wall of the cleaning groove 32 that is in contact with the pressure roller 2 is inclined. The end that is in contact with the pressure roller 2 is higher, and the end that is away from the pressure roller 2 is lower.

[0029] Furthermore, the spring 33 enables the cleaning groove 32 to fit tightly against the outer wall of the pressure roller 2. When the pressure roller 2 rotates, the asphalt particles on the surface of the pressure roller 2 are scraped off by the cleaning groove 32, thereby achieving the purpose of cleaning the pressure roller 2.

[0030] In one embodiment of this utility model, such as Figure 1 As shown, the transmission assembly 4 includes a turntable 41 and a rotating rod 42, wherein the turntable 41 is disposed at the end of the support shaft 7; the rotating rod 42 is eccentrically hinged to the turntable 41.

[0031] In the embodiments of this application, when the support shaft 7 rotates, it can drive the turntable 41 to rotate, thereby driving one end of the rotating rod 42 to rotate.

[0032] Furthermore, such as Figure 3 As shown, the cylinder assembly 5 includes a cylinder body 51, a piston 52, and a push rod 53. The cylinder body 51 is mounted on the side wall of the support plate 1; the piston 52 is slidably disposed inside the cylinder body 51; one end of the push rod 53 is connected to the piston 52, and the other end of the push rod 53 is hinged to the rotating rod 42.

[0033] It should be noted that an exhaust pipe is connected to the cylinder block 51, and a one-way valve is installed on the exhaust pipe. The one-way valve allows the gas inside the cylinder block 51 to be discharged, but does not allow external gas to enter the interior of the cylinder block 51.

[0034] Furthermore, as the turntable 41 rotates, the piston 52 can be driven to move up and down repeatedly with the cooperation of the rotating rod 42 and the push rod 53. When the piston 52 moves downward, it can generate suction on the adsorption component 6, thereby realizing the adsorption of asphalt particles.

[0035] In one embodiment of this utility model, such as Figure 1As shown, the adsorption assembly 6 includes an adsorption tank 61, two second connecting shafts 62, two connecting pipes 63, and two collection boxes 64. The two second connecting shafts 62 are respectively connected to the corresponding mounting plates 9 and to the two side walls of the adsorption tank 61. The two collection boxes 64 are respectively connected to the corresponding cylinders 51. The two connecting pipes 63 are respectively connected to the corresponding collection boxes 64 and are also connected to the adsorption tank 61.

[0036] It should be noted that the second connecting shaft 62 is a damping shaft. The angle of the adsorption tank 61 can be adjusted through the second connecting shaft 62 to better adsorb the asphalt on the cleaning shovel 32. The two collection boxes 64 are respectively set on the two side walls of the support plate 1, and a filter layer is provided at the connection between the collection box 64 and the cylinder 51 to prevent asphalt particles from entering the interior of the cylinder 51.

[0037] Specifically, when the road surface is rolled, the drive trolley is connected to the support plate 1. The drive trolley drives the support shaft 7 and the pressure roller 2 to rotate. The cleaning shovel 32 can scrape off the asphalt particles attached to the pressure roller 2. Because the asphalt particles have a certain stickiness, they will accumulate on the cleaning shovel 32.

[0038] At the same time, with the cooperation of the transmission component 4, the piston 52 is driven to move up and down reciprocally. When the piston 52 moves downward, the internal space of the cylinder 51 increases, and a certain adsorption force is generated on the cleaning shovel 32 through the connecting pipe 63 and the adsorption tank 61, thereby adsorbing the asphalt particles on the cleaning shovel 32 into the collection box 64, so as to better generate adsorption force on the roller.

[0039] In summary, the road construction roller pressing device of this utility model can effectively peel off asphalt particles from the surface of the roller and promptly adsorb them into the collection box, thereby improving the cleaning effect of the roller surface and improving the quality of road construction.
