Description

Technical Field

[0001] The present invention belongs to the technical field of asphalt construction, and specifically relates to a foreign asphalt applicability test layout and flattening device. Background Art

[0002] Asphalt is a viscoelastic material used in road construction, usually derived from petroleum processing, which acts as a cementing aggregate in asphalt concrete to form the road surface. The use of a compactor during asphalt laying is crucial as it ensures the density and uniformity of the asphalt concrete, thereby improving the load-bearing capacity and durability of the road. The compaction process helps eliminate air bubbles and voids in the mix, reduces water penetration, and prevents early damage such as the formation of cracks and potholes. In addition, proper compaction ensures a good bond between the asphalt layer and the base layer, preventing interlayer sliding and peeling. Therefore, the compactor not only improves construction efficiency, but also ensures the quality and service life of the road project.

[0003] Referring to the existing document with announcement number CN220908075U, a concrete pavement leveling device is disclosed, a flattening device for asphalt concrete pavement construction, including a mounting frame and a rotation control component, the inner wall of the mounting frame is rotatably connected with a flattening roller, the surface of the flattening roller is provided with a cleaning component for cleaning asphalt adhered to the surface of the flattening roller, a containing box for collecting asphalt is provided below the cleaning component, a locking component for limiting the containing box is provided on the surface of the mounting frame, and a traction joint is provided on the left side of the mounting frame.

[0004] The above device uses a cleaning component, mainly a scraper, arranged on the surface of the flattening roller to clean and collect the asphalt adhered to the flattening roller. However, in actual use, the scraper may gradually accumulate the adhered concrete. If the concrete adhered to the scraper cannot be cleaned in time and effectively, it will not only reduce the rotation efficiency of the flattening roller and increase the wear rate of the equipment, but also affect the compaction quality of the asphalt concrete, resulting in a decrease in the flatness of the road surface. Utility Model Content

[0005] The purpose of this scheme is to provide a flattening device for foreign asphalt applicability testing to solve the problem in the prior art that the flattening roller cannot be self-cleaned when cleaning.

[0006] In order to achieve the above-mentioned purpose, the present invention provides a foreign asphalt applicability test layout and flattening device, including a roller and a cleaning component arranged on the roller, wherein the cleaning component includes:

[0007] A cleaning roller, the cleaning roller being arranged at the rear end of the flattening roller of the roller, and the cleaning roller being rotatably connected to the support arm of the roller;

[0008] A support block, wherein the support block is arranged on the cleaning roller and has a hole;

[0009] A cleaning brush, wherein the cleaning brush is arranged on the supporting block;

[0010] A pressing block, the pressing block is slidably disposed in the hole, and the end of the pressing block away from the hole is a pressing block made of elastic material;

[0011] A spring, two ends of which are respectively connected to the inner walls of the pressing block and the supporting block.

[0012] The principle of this scheme is that when the flattening roller rotates, it comes into contact with the cleaning brush and the pressing block. The cleaning brush cleans the asphalt adhered to the flattening roller, and the pressing block is squeezed to compress the spring. After the pressing block moves away from the flattening roller, the spring drives the pressing block back to its position. The end of the pressing block is made of elastic material, which will shake and come into contact with the cleaning brush, shaking off the asphalt adhered to the cleaning brush.

[0013] The effect of this solution is that the cleaning brush can clean the asphalt adhering to the flattening roller, and the coordinated action of the pressing block and the spring realizes the self-cleaning function of the cleaning brush.

[0014] Furthermore, the number of the supporting blocks and the cleaning brushes are both multiple, and the supporting blocks are evenly arranged around the outer circumference of the cleaning roller.

[0015] The principle and effect of this solution are that there are multiple cleaning brushes that evenly surround the outer circumference of the cleaning roller. The advantage of this design is that it can increase the cleaning coverage of the flattening roller and avoid local residues.

[0016] Furthermore, the cleaning brush comprises a plurality of cylindrical cleaning rods, and the cleaning rods are arranged around the central axis of the support block.

[0017] The principle and effect of this solution is to further increase the cleaning effect of the cleaning brush.

[0018] Furthermore, the end of the pressing block is arranged in the middle of the supporting block.

[0019] The principle and effect of this solution are: increasing the amplitude range of the swing of the pressing block, so as to facilitate the transmission of the vibration generated by the pressing block to the surrounding cleaning rods.

[0020] Furthermore, it also includes a collecting trough arranged on the roller, and the collecting trough is used to collect asphalt.

[0021] The principle and effect of this solution are that the collecting trough can be arranged below the contact point between the flattening roller and the cleaning brush, and the collecting trough is not in contact with the ground. The collecting trough is arranged to collect the residual asphalt to prevent it from falling on the ground.

[0022] Furthermore, a slide groove is provided on the support block, and the pressing block is slidably connected to the slide groove.

[0023] The principle and effect of this solution are that the slide groove provides positioning and guiding functions for the movement of the pressing block.

[0024] Furthermore, it also includes a detection component, which includes a flexible chamber arranged in the support block, the chamber is provided with a marking paint, the end of the pressing block is matched with the chamber, the pressing block is provided with a channel, and the chamber is connected to the channel through a pipeline.

[0025] The principle and effect of this solution are as follows: (1) In the prior art, if the problem of excessive thickness in local areas during asphalt paving and pouring is solved by flattening and subsequent detection and leveling, it will lead to reduced construction efficiency and increased additional costs. In contrast, real-time detection during the asphalt flattening process can significantly improve construction efficiency and quality. (2) When the pressing block on the cleaning roller comes into contact with thicker asphalt, the asphalt will resist and squeeze the pressing block to compress the chamber, so that the paint in the chamber is squeezed out, and then flows through the pipeline to the tunnel, and finally flows out from the tunnel mouth, thereby spraying the paint on the thicker concrete area. (3) By setting up a detection component, this solution realizes real-time detection and marking of local over-thick areas during the asphalt paving and pouring process, thereby improving construction efficiency.

[0026] Furthermore, the travel of the pressing block after contacting the flattening roller is smaller than the distance from the end of the pressing block to the chamber.

[0027] The principle and effect of this solution is to prevent the pressing block from being squeezed into the cavity after contacting the flattening roller.

[0028] Furthermore, a one-way valve is provided on the pipeline.

[0029] The principle and effect of this solution is to make the paint in the pipeline flow in a preset direction.

[0030] Furthermore, the chamber is an airbag.

[0031] The principle and effect of this solution is that the airbag is compressed by the pressing block to make the water-based paint inside it flow out. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] The following will clearly and completely describe the concept and technical effects of the utility model in combination with the embodiments, so as to fully understand the purpose, features and effects of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, other embodiments obtained by technicians in this field without creative work are all within the scope of protection of the utility model:

[0039] Embodiment 1:

[0040] See also Figure 1-Figure 4 A foreign asphalt applicability test layout and flattening device includes a roller 1. A cleaning assembly 2 is provided on the support arm of the roller 1. The cleaning assembly 2 includes a cleaning roller 21 and a support block 22 provided on the cleaning roller 21. The cleaning roller 21 is rotatably connected to the support arm of the roller 1, and the cleaning roller 21 is provided at the rear end of the cleaning roller 11 of the roller 1. A circular blind hole is provided on the support block 22, and a pressure block 24 is slidably provided in the blind hole. A slide groove is provided on the support block 22, and the pressure block 24 is slidably connected to the slide groove. The slide groove provides positioning and guiding functions for the movement of the pressure block 24. The pressing block 24 is provided in the support block 22 and is provided with a spring 25. The two ends of the spring 25 are respectively connected to the inner wall of the pressing block 24 and the support block 22. The support block 22 is provided with a cleaning brush 23. The cleaning brush 23 includes a plurality of cylindrical cleaning sticks. The end of the pressing block 24 away from the blind hole is a pressing block made of elastic material. After contacting the side wall of the flattening roller 11, the flattening roller will squeeze and touch the pressing block 24, so that it will retract into the support block 22. At this time, the cleaning brush 23 contacts the side wall of the flattening roller 11 to clean the asphalt adhered to the flattening roller 11. When the pressing block 24 is away from the flattening roller 11, it returns to its original position driven by the spring 25. Since the end of the pressing block 24 is made of elastic material, it will shake after returning to its original position to hit the surrounding cleaning brush 23, causing it to vibrate and throw off the asphalt adhered to the cleaning brush 23. In order to facilitate the collection of the cleaned asphalt, a collection trough is provided below the contact point between the flattening roller 11 and the cleaning brush 23, and the collection trough is not in contact with the ground. This collects the remaining asphalt and prevents it from falling to the ground.

[0041] In order to further increase the cleaning effect of the cleaning brush, the number of support blocks 22 and cleaning brushes 23 are both multiple. The support blocks 22 are evenly arranged around the outer circumference of the cleaning roller 21. The cleaning brush 23 includes multiple cylindrical cleaning sticks. The cleaning sticks are arranged around the central axis of the support block 22, and the end of the pressing block 24 is arranged in the middle of the support block 22, which increases the amplitude range of the swing of the pressing block 24 and facilitates the transmission of the vibration generated by the pressing block 24 to the surrounding cleaning sticks.

[0042] Embodiment 2:

[0043] See also Figure 5 The difference between this embodiment and the previous embodiment is that it also includes a detection component 3, which includes a flexible chamber 31 arranged in the support block 22, which can be a flexible airbag, and a marking paint is provided in the chamber 31, which can be a water-based paint, and will disappear after the road surface is cleaned by spraying water. The end of the pressing block 24 is arranged in cooperation with the chamber 31, and the pressing block 24 is provided with a passage 241. The chamber 31 is connected to the passage 241 through a pipeline, and a one-way valve 32 is provided on the pipeline, and the flow path of the one-way valve 32 is from the chamber 31 to the passage 241. In the prior art, if the problem of excessive thickness in the local area during the asphalt paving and pouring process is solved by later detection and leveling after flattening, it will lead to a decrease in construction efficiency and an increase in additional costs. In contrast, real-time detection during the asphalt flattening process can significantly improve construction efficiency and quality. When the pressing block 24 on the cleaning roller 21 contacts the thicker asphalt, the asphalt will resist and squeeze the pressing block 24 to compress the chamber 31, so that the paint in the chamber 31 is squeezed out, and then flows to the tunnel 241 through the pipeline, and finally flows out from the port of the tunnel 241, so that the paint is sprayed on the thicker area of ​​the concrete. In order to prevent the pressing block from being squeezed into the chamber after contacting the flattening roller, the travel of the pressing block 24 after contacting the flattening roller 11 can be limited to be less than the distance from the end of the pressing block 24 to the chamber 31, and the travel of the pressing block 24 generated by the thicker asphalt to squeeze the pressing block 24 is greater than the distance from the end of the pressing block 24 to the chamber 31.

[0044] The above is only an embodiment of the utility model, and the common knowledge such as the known specific structure and characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the structure of the utility model, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
