Description

Technical Field

[0001] This utility model relates to the field of road construction technology, and in particular to a paving frame for improving the smoothness of asphalt pavement. Background Technology

[0002] Asphalt is a dark brown complex mixture composed of hydrocarbons of different molecular weights and their non-metallic derivatives. It is a type of high-viscosity organic liquid. When mixed with aggregates, it can be used as a material for asphalt pavement. At the same time, it needs to be compacted quickly using a road roller during paving.

[0003] The announcement number CN214737170U discloses an asphalt paving device for asphalt pavement construction. When the roller is rolling the asphalt pavement normally, the scraper can quickly scrape off the asphalt on the surface of the roller and guide the asphalt to the front of the roller, so that the surface of the roller is always kept clean, thereby improving the smoothness of the road surface rolled by the roller.

[0004] However, during the use of this device, the scraper makes contact with the roller through a spring, but after long-term use, the spring is prone to fatigue and loss of elasticity, which may result in the scraper and roller not fitting tightly together, causing asphalt residue to accumulate. Therefore, this utility model proposes a paving frame to improve the smoothness of asphalt pavement to solve the problems existing in the prior art. Utility Model Content

[0005] To address the aforementioned problems, this utility model proposes a paving frame for improving the smoothness of asphalt pavement. This solves the problem that in the prior art, the scraper achieves contact with the compaction wheel through a spring, but after long-term use, the spring is prone to fatigue and loss of elasticity, which may result in the scraper and compaction wheel not fitting tightly together, causing asphalt residue to accumulate.

[0006] To achieve the objectives of this utility model, the following technical solution is adopted:

[0007] A paving frame for improving the smoothness of asphalt pavement includes a fixed frame, a roller rotatably connected to the inner side of the fixed frame, an mounting frame fixedly installed on the top of the roller, a mounting seat engaged on the inner side of the mounting frame, a positioning frame penetrating the inner side of the mounting seat, an installation opening adapted to the mounting seat on the top of the mounting frame, a communication opening for the positioning frame to pass through on the bottom of the mounting frame, multiple first positioning holes on the left and right sides of the mounting seat, multiple rows of second positioning holes adapted to the first positioning holes on the inner side of the positioning frame near the top, each row of second positioning holes including multiple second positioning holes evenly distributed vertically, positioning components on the inner side of the mounting frame and located on the left and right sides of the mounting seat for positioning the mounting seat and the positioning frame in conjunction with the first and second positioning holes, and a cleaning component on the inner side of the positioning frame for cleaning the surface of the roller.

[0008] A further improvement is that cleaning rollers are rotatably connected to the inner side of the mounting bracket near the left and right sides.

[0009] A further improvement is that: the front and rear sides of the fixed frame are rotatably connected to a first grooved wheel, and the surface of the mounting frame and above the first grooved wheel are rotatably connected to a second grooved wheel. The first grooved wheel and the second grooved wheel are connected by a belt drive. The first grooved wheel and the second grooved wheel are respectively fixedly connected to one end of the rolling wheel and the cleaning roller on the side near the fixed frame.

[0010] A further improvement is that the positioning component includes a threaded rod, the left and right ends of which are rotatably connected to the inner sidewall of the mounting bracket, a movable plate is threadedly connected to the surface of the threaded rod, a positioning rod adapted to the first positioning hole is fixedly installed on the side of the movable plate near the mounting base, and adjusting blocks that drive the threaded rod to rotate are rotatably connected to the left and right sides of the mounting bracket.

[0011] A further improvement is that: the inner side of the mounting bracket is provided with a sliding groove for the movable plate to slide left and right, and the inner side of the mounting bracket is provided with a connecting hole for the positioning rod to pass through.

[0012] A further improvement is that the cleaning assembly includes a scraper, the bottom of the positioning frame has a lifting port for the scraper to slide up and down, multiple lifting rods are fixedly installed on the top inner side of the lifting port, the multiple lifting rods are evenly distributed on the inner side of the lifting port, the top of the scraper has a lifting hole that is slidably connected to the lifting rod, and a spring for driving the scraper to descend is provided on the inner side wall of the lifting port and at the outer edge of the lifting rod.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. The positioning assembly, through the cooperation of threaded rod, moving plate and positioning rod, can quickly and accurately fix or disassemble the mounting base and positioning frame, which facilitates the maintenance of the positioning frame and cleaning assembly or the replacement of springs and other components. This further simplifies the disassembly and assembly process, greatly shortens the maintenance time, reduces construction interruptions caused by equipment maintenance, and ensures the smooth progress of construction.

[0015] 2. When the spring's elasticity diminishes, the height of the positioning frame can be adjusted using the positioning assembly. The positioning rod can be inserted into the second positioning hole at different positions to compensate for the insufficient spring elasticity, temporarily maintaining close contact between the scraper and the compaction wheel. This avoids immediate work stoppage and replacement due to spring problems, extends the continuous working time of the device, and ensures that the smoothness of the road surface paving is not affected.

[0021] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0022] according to Figure 1-4As shown, this embodiment proposes a solution to improve the smoothness of asphalt pavement: a paving frame for improving the smoothness of asphalt pavement; including a fixed frame 1, a roller 2 rotatably connected to the inner side of the fixed frame 1, an mounting frame 3 fixedly installed on the top of the roller 2, a mounting seat 5 engaged on the inner side of the mounting frame 3, a positioning frame 6 penetrating the inner side of the mounting seat 5, an installation opening 7 adapted to the mounting seat 5 on the top of the mounting frame 3, a communication opening for the positioning frame 6 to pass through on the bottom of the mounting frame 3, multiple first positioning holes 8 on the left and right sides of the mounting seat 5, multiple rows of second positioning holes 9 adapted to the first positioning holes 8 on the inner side of the positioning frame 6 near the top, each row of second positioning holes 9 including multiple second positioning holes 9 evenly distributed vertically, positioning components are provided on the inner side of the mounting frame 3 and located on the left and right sides of the mounting seat 5, used to position the mounting seat 5 and the positioning frame 6 in conjunction with the first positioning holes 8 and the second positioning holes 9, and a cleaning component is provided on the inner side of the positioning frame 6 for cleaning the surface of the roller 2.

[0023] In this embodiment, the mounting base 5 is engaged with the mounting frame 3 through the mounting port 7, and the positioning frame 6 extends through the inner side of the mounting frame 3 through the connecting port to a suitable position. The mounting base 5 and the positioning frame 6 are positioned by the positioning component, the first positioning hole 8 and the second positioning hole 9. Based on the contact pressure between the scraper 16 and the compaction wheel 2, the positioning frame 6 is positioned at a suitable height, which to some extent compensates for the insufficient elasticity of the spring 19, temporarily maintains the close contact between the scraper 16 and the compaction wheel 2, and extends the service life of the device. In order to avoid the impact of work stoppage on the construction progress, and at the same time ensure the flatness of the road surface paving, the mounting base 5 can be quickly and accurately fixed or disassembled, which facilitates the maintenance or replacement of the positioning frame 6 and the cleaning component. Through the action of the cleaning component, a stable contact pressure is maintained, and the cleaning effect is improved.

[0024] The front and rear sides of the fixed frame 1 are rotatably connected to the first grooved wheel 10, and the surface of the mounting frame 3 and above the first grooved wheel 10 are rotatably connected to the second grooved wheel 11. The first grooved wheel 10 and the second grooved wheel 11 are connected by belt drive. The first grooved wheel 10 and the second grooved wheel 11 are respectively fixedly connected to the rolling wheel 2 and the cleaning roller 4 on the side near the fixed frame 1. When the rolling wheel 2 rotates, it will drive the first grooved wheel 10 fixedly connected to it to rotate synchronously. The first grooved wheel 10 drives the second grooved wheel 11 to rotate through the belt, so that the cleaning roller 4 rotates together with the rolling wheel 2, which can assist in cleaning the surface of the rolling wheel 2 and improve the cleaning efficiency in conjunction with the cleaning component.

[0025] The positioning assembly includes a threaded rod 12, with its left and right ends rotatably connected to the inner wall of the mounting bracket 3. A movable plate 13 is threadedly connected to the surface of the threaded rod 12. A positioning rod 14, which is adapted to the first positioning hole 8, is fixedly installed on the side of the movable plate 13 near the mounting base 5. Adjusting blocks 15, which drive the threaded rod 12 to rotate, are rotatably connected to the left and right sides of the mounting bracket 3. By rotating the adjusting blocks 15, the threaded rod 12 is driven to rotate inside the mounting bracket 3. The threaded rod 12 drives the movable plate 13 to move through the threaded connection. The movable plate 13 drives the positioning rod 14 to move synchronously. When the positioning rod 14 is inserted into the first positioning hole 8 on the side of the mounting base 5 and inserted into the inner side of the adjacent second positioning hole 9, the positioning bracket 6 is positioned at a suitable height, which can quickly and accurately fix or remove the mounting base 5, thereby facilitating the maintenance or replacement of the positioning bracket 6 and the cleaning assembly.

[0026] The mounting bracket 3 has a sliding groove on its inner side for the movable plate 13 to slide left and right, and a connecting hole on its inner side for the positioning rod 14 to pass through. The sliding groove allows the movable plate 13 to move stably.

[0027] The cleaning assembly includes a scraper 16. The bottom of the positioning frame 6 has a lifting port for the scraper 16 to slide up and down. Multiple lifting rods 17 are fixedly installed on the top inner side of the lifting port. The lifting rods 17 are evenly distributed inside the lifting port and guide the scraper 16 to slide up and down, preventing the scraper 16 from deviating during operation and ensuring the stability of the scraping action. The top of the scraper 16 has a lifting hole 18 that slides with the lifting rods 17. A spring 19 is provided on the inner side wall of the lifting port and located at the outer edge of the lifting rods 17 to drive the scraper 16 to descend. Under the elastic force of the spring 19, the scraper 16 is always subjected to downward pressure, so that its bottom is in close contact with the surface of the roller 2. When the roller 2 rotates, the scraper 16 can scrape off the residual asphalt on its surface, reducing the accumulation of asphalt residue.

[0028] The above embodiment discloses a paving frame for improving the smoothness of asphalt pavement. The mounting base 5 is engaged within the mounting frame 3 via the mounting port 7. The positioning frame 6 extends through the inner side of the mounting frame 3 via a connecting port to a suitable height. By rotating the adjusting block 15, the threaded rod 12 rotates within the mounting frame 3. The threaded rod 12, through a threaded connection, moves the moving plate 13. The moving plate 13 then moves the positioning rod 14 synchronously. When the positioning rod 14 is inserted into the first positioning hole 8 on the side of the mounting base 5 and then into the adjacent second positioning hole 9, the positioning frame 6 is positioned at a suitable height. This allows for quick and accurate fixing or disassembly of the mounting base 5, facilitating the positioning frame. 6. The cleaning components are maintained or replaced. Under the elastic force of the spring 19, the scraper 16 is always under downward pressure, so that its bottom is in close contact with the surface of the roller 2. When the roller 2 rotates, the scraper 16 can scrape off the residual asphalt on its surface, reducing the accumulation of asphalt residue. When the spring 19 shows slight elasticity decay, the adjusting block 15 can be rotated in the opposite direction to make the positioning rod 14 disengage from the inside of the second positioning hole 9, so that the positioning frame 6 slides down to a suitable height inside the mounting base 5, and then is inserted into the adjacent second positioning hole 9 through the positioning rod 14, thereby extending the service life of the device, avoiding the impact of work stoppage on the construction progress, and ensuring the flatness of the road surface paving.
