Description

Technical Field

[0001] This invention relates to the field of municipal engineering technology, specifically to a municipal road compaction equipment and construction method. Background Technology

[0002] A road roller is a type of engineering machinery used for compacting soil, asphalt, concrete, and other ground surfaces. It primarily uses the weight and vibration of its rollers to compact loose granular materials on the ground, increasing the density and load-bearing capacity of the surface, making it more suitable for the construction and use of roads, railways, airport runways, etc. Road rollers compact loose granular materials on the ground through the weight and vibration of the rollers, making them tightly bound and improving the load-bearing capacity and stability of the ground. Static road rollers rely mainly on their own weight and static pressure for compaction; while vibratory road rollers, in addition to static pressure, can also improve the compaction effect through the dynamic force generated by the vibration system. Currently, the application of road rollers is relatively limited, often only allowing for static compaction or vibratory compaction.

[0003] The information disclosed in this background section is intended only to enhance the understanding of the overall background of the invention and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the above-mentioned technical defects and provide a municipal road compaction equipment and construction method. This equipment can not only improve the vibration effect of the compaction roller, but also perform secondary compaction, improve the compaction effect, and reduce the number of round trips of the road roller.

[0005] To solve the above problems, the technical solution of the present invention is: a municipal road compaction device, including a frame, a driver's cab at the upper end of the frame, a protective shell at the front end of the frame, and a movable compaction roller inside the protective shell; A vibration structure is disposed inside the compaction roller; A double-pressure structure is provided at the bottom of the inner part of the protective shell; A cleaning structure is provided inside the upper part of the protective shell; A filler filling structure is disposed at the lower end of the frame; The pressure-reinforcing structure includes a motor, which is fixedly connected inside the protective shell. A rotating shaft is fixedly connected to the lower output end of the motor. Two pulleys are fixedly connected to the surface of the rotating shaft. Multiple rotating shafts are provided on both sides of the rotating shaft. The rotating shafts are rotatably connected inside the protective shell. Two pulleys are fixedly connected to the surface of the rotating shafts. A belt is fitted between the corresponding pulleys. A rotating cylinder is fixedly connected to the lower end of both rotating shafts. A lifting cylinder is slidably connected to the surface of the rotating cylinder. A pressure plate is fixedly connected to the lower end of the lifting cylinder.

[0006] Preferably, the rotating cylinder has vertical grooves on both sides and an oblique arc groove on its surface. The two ends of the arc groove are connected to the groove. A spring is fixedly connected to the upper end of the lifting cylinder. The upper end of the spring is fixedly connected to the protective shell. A spring is fixedly connected to the inside of both ends of the upper part of the lifting cylinder. A sliding rod is fixedly connected to the other end of the spring and is slidably connected to the inside of the groove.

[0007] Preferably, the filler filling structure includes: The material bin is fixedly connected to the inner cavity at the bottom of the frame, and one end of the material bin is connected to a flexible hose; A lead screw is rotatably connected inside the frame. A motor is provided at one end of the lead screw. A sliding slider is fitted on the surface of the lead screw and is slidably connected inside the frame. A flexible tube is fixedly connected to the slider.

[0008] Preferably, the vibration structure includes: A ring shell is fixedly connected to both ends of the compaction roller. A motor three is fixedly connected inside the ring shell. A rotating rod one is fixedly connected to the output end of the motor three. Rotating rod two is provided on both sides of rotating rod one. An eccentric wheel is fixedly sleeved on the surface of rotating rod two. A pulley three is sleeved on the surface of rotating rod two. A pulley four is sleeved on the surface of rotating rod one. A belt two is sleeved on the surfaces of pulley three and pulley four.

[0009] Preferably, the cleaning structure includes multiple spring damping rods, one end of which is fixedly connected to the protective shell, and the other end of which is fixedly connected to a scraper, one end of which contacts the compaction roller.

[0010] This invention also discloses a construction method for a municipal road compaction device, comprising the following steps: Step 1: Construction preparation, including site clearing and foundation treatment, and compacting the original ground surface using municipal road compaction equipment; Step 2: Preparation and filling of roadbed fill material; after filling, re-compaction is carried out. Step 3: Compaction degree and flatness test; Step 4: Maintenance and Protection.

[0011] The advantages of this invention compared to existing technologies are: (1) The invention starts the moving equipment. The motor three starts and drives the rotating rod one to rotate. The rotating rod one drives the pulley four to rotate, and then drives the pulley three to rotate through the belt two, which in turn drives the rotating rod two to rotate. This can drive the eccentric wheel to rotate, thereby using the compaction roller to vibrate as a whole. Thus, the compaction roller vibration can continuously compact the road surface. One end of the scraper plate contacts the compaction roller, and the scraper plate can remove the soil and debris stuck to the surface of the compaction roller in real time. (2) When the motor of the present invention starts, it drives the shaft to rotate, and then drives the shaft and multiple shafts to rotate through the pulley, the pulley and the belt, and then drives all the rotating cylinders to rotate. The rotating cylinder drives the slide rod to rise through the arc groove, and then drives the lifting cylinder to rise. The lifting cylinder compresses the spring. When the slide rod moves to the top of the arc groove, the slide rod enters the groove. At this time, the slide rod moves down quickly under the action of gravity and the spring, and then drives the lifting cylinder and the secondary pressure plate to move down quickly, so that the secondary pressure plate compacts the road surface a second time. When the motor rotates continuously, it will continuously drive the secondary pressure plate to compact the road surface. (3) The motor of the present invention starts in both directions and drives the lead screw to rotate in both directions, thereby driving the slider to move back and forth along the direction of the lead screw, thereby driving the hose to move back and forth, so that the filler is evenly covered on the road surface.

[0020] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings. Identical components are indicated by the same reference numerals.

[0021] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions shown in the attached diagram, while the terms “inside” and “outside” refer to the directions toward or away from the geometric center of a specific component, respectively.

[0022] To make the content of this invention easier to understand, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0023] like Figure 1-7 As shown, a municipal road compaction device includes a frame 1, a driver's cab 2 mounted on the upper end of the frame 1, a protective shell 3 mounted on the front end of the frame 1, and a movable compaction roller 4 installed inside the protective shell 3; a vibration structure 5 is disposed inside the compaction roller 4; the vibration structure 5 includes a ring shell 27, which is fixedly connected to both ends of the compaction roller 4, a motor 28 is fixedly connected inside the ring shell 27, a rotating rod 29 is fixedly connected to the output end of the motor 28, rotating rods 30 are mounted on both sides of the rotating rods 29, and an eccentric wheel 31 is fixedly sleeved on the surface of the rotating rods 30. The three pulleys 32 and 4 are mounted on the surface of the rotating rod 29. The two belts 34 are mounted on the surface of the three pulleys 32 and 4. When the motor 3 28 is started, it can drive the rotating rod 29 to rotate. The rotating rod 29 drives the pulley 4 33 to rotate, which in turn drives the pulley 32 to rotate through the belt 2 34. This drives the rotating rod 2 30 to rotate, which can drive the eccentric wheel 31 to rotate. This causes the compaction roller 4 to vibrate as a whole. The compaction roller 4 moves with the whole equipment, so the vibration of the compaction roller 4 can continuously compact the road surface and improve the compaction effect.

[0024] The pressure structure 6 is located at the bottom of the inner part of the protective shell 3. The pressure structure 6 includes a motor 9, which is fixedly connected to the inside of the protective shell 3. A rotating shaft 10 is fixedly connected to the lower output end of the motor 9. Two pulleys 12 are fixedly connected to the surface of the rotating shaft 10. Multiple rotating shafts 11 are installed on both sides of the rotating shaft 10. The rotating shafts 11 are rotatably connected to the inside of the protective shell 3. Two pulleys 13 are fixedly connected to the surface of the rotating shafts 11. A belt 35 is fitted between the corresponding pulleys 12 and 13. A rotating cylinder 14 is fixedly connected to the lower end of both the rotating shafts 10 and 11. A lifting cylinder 15 is slidably connected to the surface of the rotating cylinder 14. A pressure plate 16 is fixedly connected to the lower end of the lifting cylinder 15. Vertical grooves 19 are provided on both sides of the rotating cylinder 14. An oblique arc groove 18 is installed on the surface of the rotating cylinder 14. The two ends of the arc groove 18 are respectively connected to the groove 19. A spring 17 is fixedly connected to the upper end of the lifting cylinder 15. The upper end of the spring 17 is fixedly connected to the protective shell 3. A spring 21 is fixedly connected to the inside of both ends of the upper part of the lifting cylinder 15. A sliding rod 20 is fixedly connected to the other end of the spring 21. The sliding rod 20 is slidably connected to the inside of the groove 19. When motor 9 starts, it drives shaft 10 to rotate, which in turn drives shaft 10 and multiple shafts 11 to rotate via pulleys 12 and 13 and belt 35. This, in turn, drives all the rotating cylinders 14 to rotate. The rotating cylinders 14 drive the slide rod 20 to rise through the arc groove 18, which in turn drives the lifting cylinder 14 to rise. The lifting cylinder 14 compresses spring 17. When the slide rod 20 moves to the top of the arc groove 18, it enters the slide groove 19. At this time, the slide rod 20 moves rapidly downward under the action of gravity and spring 17, which in turn drives the lifting cylinder 15 and the secondary pressure plate 16 to move rapidly downward, so that the secondary pressure plate 16 performs secondary compaction on the road surface. As motor 9 continues to rotate, it continuously drives the secondary pressure plate 16 to compact the road surface. During the movement of the slide rod 20, spring 21 deforms to adapt to the surface curvature of the rotating cylinder 14.

[0025] The cleaning structure 7 is located inside the upper part of the protective shell 3. The cleaning structure 7 includes multiple spring damping rods 36. One end of the spring damping rod 36 is fixedly connected to the protective shell 3, and the other end of the spring damping rod 36 is fixedly connected to a scraper 37. One end of the scraper 37 contacts the compaction roller 4. The scraper 37 can remove soil and debris adhering to the surface of the compaction roller 4 in real time. The compaction roller 4 vibrates under the action of the vibration structure 5, which will continuously squeeze the scraper 37. The scraper 37 will squeeze the spring damping rod 36, causing the scraper 37 to move slowly, ensuring that the scraper 37 always keeps in contact with the compaction roller 4.

[0026] The filler filling structure 8 is located at the lower end of the frame 1. The filler filling structure 8 includes a material box 22, which is fixedly connected to the inner cavity at the bottom of the frame 1. One end of the material box 22 is connected to a flexible hose 26. A lead screw 23 is rotatably connected inside the frame 1. A motor 24 is installed at one end of the lead screw 23. A sliding slider 25 is mounted on the surface of the lead screw 23 and is slidably connected inside the frame 1. The flexible hose 26 is fixedly connected to the slider 25. The motor 24 can rotate the lead screw in both directions, thereby causing the slider 25 to move back and forth along the direction of the lead screw 23, which in turn causes the flexible hose 26 to move back and forth, ensuring that the filler is evenly distributed and covered on the road surface.

[0027] In practical use, the site for compaction is first cleaned and the base is treated. Then, municipal road compaction equipment is used to compact the original ground. After the roadbed filler is prepared, it is compacted again after the filler is filled. After the construction is completed, the compaction degree and flatness are tested. Then, maintenance and protection are carried out.

[0028] The specific process of using municipal road compaction equipment is as follows: First compaction: Start the equipment and move it. Motor 328 starts and drives the rotating rod 129 to rotate. The rotating rod 129 drives the pulley 433 to rotate, which in turn drives the pulley 32 to rotate via belt 234, which in turn drives the rotating rod 20 to rotate. This drives the eccentric wheel 31 to rotate, thus causing the compaction roller 4 to vibrate as a whole. The vibration of the compaction roller 4 can continuously compact the road surface. One end of the scraper 37 contacts the compaction roller 4, and the scraper 37 can remove soil and debris adhering to the surface of the compaction roller 4 in real time. Motor 19 starts and drives the rotating shaft 10 to rotate, which in turn drives the rotating shaft 10 and multiple rotating shafts 21 to rotate via pulley 12, pulley 23 and belt 13, which in turn drives all the... Rotating cylinder 14 rotates, and rotating cylinder 14 drives sliding rod 20 to rise through arc groove 18, which in turn drives lifting cylinder 14 to rise. Lifting cylinder 14 compresses spring 17. When sliding rod 20 moves to the top of arc groove 18, sliding rod 20 enters the sliding groove 19. At this time, sliding rod 20 moves rapidly downward under the action of gravity and spring 17, which in turn drives lifting cylinder 15 and secondary pressure plate 16 to move rapidly downward, so that secondary pressure plate 16 compacts the road surface a second time. When motor 9 rotates continuously, it will continuously drive secondary pressure plate 16 to compact the road surface. Motor 24 starts in both directions and drives screw to rotate in both directions, which drives slider 25 to move back and forth along the direction of screw 23, which in turn drives hose 26 to move back and forth, so that filler is evenly covered on the road surface.

[0029] Second compaction: The equipment is started and moved. Motor 328 starts, driving rotating rod 129 to rotate. Rotating rod 129 drives pulley 433 to rotate, which in turn drives pulley 323 via belt 234, which in turn drives rotating rod 230 to rotate. This drives eccentric wheel 31 to rotate, causing the compaction roller 4 to vibrate as a whole. The vibration of compaction roller 4 continuously compacts the road surface. One end of scraper 37 contacts compaction roller 4, and scraper 37 can remove soil and debris adhering to the surface of compaction roller 4 in real time. Motor 19 starts, driving rotating shaft 10 to rotate, which in turn drives pulley 12, pulley 213, and belt 13 to rotate... Rotating shaft 10 and multiple rotating shafts 11 rotate, thereby driving all rotating cylinders 14 to rotate. The rotating cylinders 14 drive the sliding rod 20 to rise through the arc groove 18, which in turn drives the lifting cylinder 14 to rise. The lifting cylinder 14 compresses the spring 17. When the sliding rod 20 moves to the top of the arc groove 18, the sliding rod 20 enters the sliding groove 19. At this time, the sliding rod 20 moves rapidly downward under the action of gravity and the spring 17, thereby driving the lifting cylinder 15 and the secondary pressure plate 16 to move rapidly downward, so that the secondary pressure plate 16 performs secondary compaction on the road surface. When the motor 9 rotates continuously, it will continuously drive the secondary pressure plate 16 to compact the road surface.
