Description

Technical Field

[0001] This invention relates to the field of municipal road construction equipment technology, and in particular to a municipal road construction equipment and its construction method. Background Technology

[0002] Municipal roads connect all areas of a city, serving as a means of transportation and pedestrian access, facilitating residents' lives, work, and cultural and recreational activities, and connecting with roads outside the city to bear external traffic burdens. Due to urban development, population concentration, and a surge in various modes of transportation, urban traffic is becoming increasingly congested. Public buses travel slowly, roads are blocked, and traffic accidents are frequent. Solving the increasingly dilapidated urban road problem has become a crucial issue. Measures that have been implemented or are under research include repairing or reconstructing the existing surface road system, and constructing new urban expressways, arterial roads, and ring roads to alleviate and disperse through traffic and intra-city traffic, reduce traffic pressure in the city center, and improve surface traffic conditions.

[0003] A rammer is a machine used to compact road surfaces; it is mainly used in road construction to level and compact the foundation. It is a compaction machine that uses impact and impact vibration to compact backfill soil in layers. It can also use impact and impact vibration to break up road surfaces in layers for ditching and the repair and maintenance of old road surfaces.

[0004] After repairs, municipal roads are prone to unevenness, leading to bumpy rides, poor road conditions, and in severe cases, endangering driving safety. A rammer is needed to level the repaired road surface. Currently, road rollers or compactors are commonly used, but both require large construction areas and long construction periods, making them unsuitable for small-scale municipal road repairs. Manual compaction is extremely time-consuming, labor-intensive, and ineffective. Therefore, designing a municipal road construction equipment suitable for small-scale operations and with fast compaction speed is crucial. In light of this, we propose a municipal road construction equipment and its construction method. Summary of the Invention

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] 1. This invention improves the structure of existing municipal road construction equipment by installing a compaction mechanism inside the rammer housing. A guide assembly and a drive assembly are mounted on the top plate of the compaction mechanism. A reduction motor on the mounting frame of the drive assembly drives a rotating handle to rotate, which in turn drives a connecting rod. The other end of the connecting rod is connected to a connecting seat, which in turn drives a movable disc to slide on a fixed guide column. The movable disc drives a central column and a transmission housing to pass through the chassis, thus compacting the bottom surface. This invention provides a compaction mechanism with good compaction effect and high efficiency, suitable for compaction operations in small areas after municipal road repairs, saving equipment and labor costs.

[0015] 2. This invention features two fixed guide pillars at the bottom of the top plate, a fixed plate seat fitted on the fixed guide pillars, and two movable guide pillars symmetrically positioned at the bottom of the fixed plate seats relative to the outer side of the fixed guide pillars. Movable plate seats are fitted at the bottom of the two movable guide pillars and the two fixed guide pillars. A first spring and a second spring are respectively fitted on the fixed guide pillars and the movable guide pillars. The drive assembly drives the movable plate seats to slide on the fixed guide pillars, and the movable plate seats drive the central pillar at the bottom to slide on the base plate. The base plate drives the transmission shell to compact the repaired municipal road surface. This invention has a small equipment size, is convenient for operation in small areas, and is easy to move, significantly reducing the cost of municipal road repair and contributing to energy conservation.

[0016] 3. This invention features a mounting frame at the bottom of the top plate, with a reduction motor mounted on the frame. The reduction motor drives a rotating handle to rotate, which in turn drives a connecting rod, a rotating shaft, and a connecting seat, causing the movable plate to slide on a fixed guide column. The movable plate then drives the central column at the bottom to slide on the base plate, which in turn drives the transmission shell to compact the repaired municipal road surface. The driving component in this invention has strong compaction force and good compaction effect, which helps to improve construction efficiency and enhance the value of production equipment.

[0017] 4. This invention uses connecting frames at both ends of the slider, with a lead screw inserted between the two connecting frames. A servo motor drives the lead screw to rotate on the connecting frames. Since the moving block is adapted to the lead screw, the rotation of the lead screw causes the moving block to slide on the slide groove. When the moving block moves to both ends of the lead screw, it causes the slider to vibrate violently on the slide column. When the moving block moves to the center of the lead screw, the slider stops vibrating. The variable stroke component allows the vibration mechanism to adjust the intensity of the vibration in real time according to the needs, resulting in precise control and good vibration breaking effect, which is beneficial to improving the construction effect of the equipment.

[0018] 5. This invention improves the construction quality of municipal roads by installing a stepper motor at the top of the top frame, which drives the rotating disk to rotate. The rotating disk drives the ball joint rod to rotate, and the ball joint rod drives the ball joint seat and slider to vibrate on the sliding column. The slider drives the transmission rod and the tamping head to produce a vibration and breaking effect on the ground protrusions. Attached Figure Description

This invention improves the structure of existing municipal road construction equipment by installing a compaction mechanism 4 inside the rammer housing 2 of the rammer 1. A guide component 402 and a drive component 403 are installed on the top plate 401 of the compaction mechanism 4. A reduction motor 4032 on the mounting bracket 4031 of the drive component 403 drives a rotating handle 4033 to rotate.

The movable disc seat 4024 drives a central column 4027 and a transmission housing 5 to pass through a base plate 4028, thus compacting the bottom surface. The compaction mechanism 4 of this invention has good compaction effect and high compaction efficiency, and is suitable for compaction operations in small areas after municipal road repairs, saving equipment and labor costs.

[0037] Specifically, the guide assembly 402 includes fixed guide posts 4021, fixed disc base 4022, movable guide posts 4023, movable disc base 4024, a first spring 4025, a second spring 4026, a center post 4027, and a base 4028. The fixed guide posts 4021 are symmetrically connected to the bottom end of the top plate 401. The fixed disc base 4022 is sleeved on several fixed guide posts 4021. The movable guide posts 4023 are symmetrically connected to the bottom end of the fixed disc base 4022 at positions relative to the outside of the fixed guide posts 4021. The movable disc base 4024 is movably inserted through the fixed guide posts 4021. On the fixed guide post 4021 and the movable guide post 4023, the first spring 4025 is sleeved on the fixed guide post 4021 at a position relative to the fixed disk seat 4022 and the movable disk seat 4024, and the second spring 4026 is sleeved on the movable guide post 4023 at a position relative to the bottom end of the movable disk seat 4024.

One end of the center post 4027 is connected to the bottom end of the movable disk seat 4024, and the other end of the center post 4027 is connected to the conductive housing 5. The center post 4027 passes through the chassis 4028. This invention features two fixed guide posts 4021 at the bottom of the top plate 401, a fixed plate seat 4022 fitted onto the fixed guide posts 4021, two movable guide posts 4023 symmetrically arranged at the bottom of the fixed plate seat 4022 relative to the outer side of the fixed guide posts 4021, and movable plate seats 4024 fitted onto the bottom of the two movable guide posts 4023 and the two fixed guide posts 4021. A first spring 4025 and a second spring 4026 are respectively fitted onto the fixed guide posts 4021 and the movable guide posts 4023. The driving assembly 403 drives the movable plate seat 4024 to slide on the fixed guide posts 4021, and the movable plate seat 4024 drives the central column 4027 at its bottom to slide on the base plate 4028. The base plate 4028 drives the transmission shell 5 to compact the repaired municipal road surface. This invention has a small equipment size, is convenient for small-area operations and easy to move, significantly reduces the cost of municipal road repair and is beneficial for energy conservation.

[0038] Furthermore, the drive assembly 403 includes a mounting bracket 4031, a geared motor 4032, a rotary handle 4033, a connecting rod 4034, a rotating shaft 4035, and a connecting seat 4036. The mounting bracket 4031 is connected to the bottom end of the top plate 401 on one side relative to the fixed guide post 4021. The geared motor 4032 is mounted on the mounting bracket 4031. The rotary handle 4033 is connected to the output end of the geared motor 4032. The connecting seat 4036 is connected to the bottom end of the fixed plate base 4022 at a position relative to the center. The rotating shaft 4035 is connected to the connecting seat 4036. One end of the connecting rod 4034 is connected to the end of the rotary handle 4033 away from the geared motor 4032, and the other end of the connecting rod 4034 is connected to the rotating shaft 4035. This invention provides a mounting frame 4031 at the bottom of the top plate 401, and a reduction motor 4032 on the mounting frame 4031. The reduction motor 4032 drives the rotating handle 4033 to rotate, which in turn drives the connecting rod 4034, the rotating shaft 4035, and the connecting seat 4036, causing the movable plate seat 4024 to slide on the fixed guide post 4021. The movable plate seat 4024 drives the central post 4027 at the bottom to slide on the base plate 4028, and the base plate 4028 drives the transmission shell 5 to compact the repaired municipal road surface. In this invention, the driving component 403 has strong compaction force and good compaction effect, which is conducive to improving construction efficiency and increasing the value of production equipment.

[0039] Furthermore, the vibration mechanism 6 includes a support component 601, a range-changing component 602, and a vibration component 603. The support component 601 is located inside the transmission housing 5, the range-changing component 602 is located on the support component 601 relative to the inside of the transmission housing 5, and the vibration component 603 is located at the bottom of the transmission housing 5 relative to the bottom of the range-changing component 602. By setting the support component 601, range-changing component 602, and vibration component 603 inside the transmission housing 5, this invention allows the compaction mechanism 4 to compact materials, while the vibration component 603 generates a slight vibration effect after compaction to clear protrusions on municipal road surfaces. This invention enhances the functionality of the equipment, enabling different construction effects to be achieved with a single device, shortening the construction cycle, and improving the construction quality of municipal roads.

[0040] It is worth noting that the support assembly 601 includes a sliding column 6011, a top frame 6012, a slider 6013, and a groove 6014. The sliding columns 6011 are symmetrically arranged inside the conductive housing 5. The top frame 6012 is located inside the conductive housing 5 relative to the top of the sliding columns 6011. The slider 6013 is slidably sleeved on the sliding columns 6011 relative to the bottom of the top frame 6012. The groove 6014 is opened on the slider 6013. The stroke variable assembly 602 is located on the groove 6014. The oscillation assembly 603 is located on the top frame 6012. The present invention symmetrically arranges two sliding pillars 6011 inside the conductive housing 5, sets a top frame 6012 at the top of the sliding pillars 6011, fits a slider 6013 on the sliding pillars 6011, and opens a sliding groove 6014 on the slider 6013. The variable range component 602 is set on the sliding groove 6014, and the support component 601 plays a role in bearing the load, which facilitates the installation of the variable range component 602 and the oscillation component 603 inside the conductive housing 5.

[0041] It is worth noting that the variable stroke assembly 602 includes a connecting frame 6021, a lead screw 6022, a servo motor 6023, and a moving block 6024. The connecting frame 6021 is connected to both ends of the slider 6013, the lead screw 6022 is connected to the connecting frame 6021, the servo motor 6023 is connected to the connecting frame 6021 at a position relative to one end of the lead screw 6022, the moving block 6024 is sleeved on the lead screw 6022 at a position relative to the slide groove 6014, and the moving block 6024 and the slide groove 6014 are size-matched. One end of the oscillation assembly 603 is connected to the moving block 6024, and the other end of the oscillation assembly 603 is connected to the top frame 6012. This invention provides a connecting frame 6021 at both ends of the slider 6013, with a lead screw 6022 inserted between the two connecting frames 6021. A servo motor 6023 drives the lead screw 6022 to rotate on the connecting frame 6021. Since the moving block 6024 is adapted to the lead screw 6022, the rotation of the lead screw 6022 causes the moving block 6024 to slide on the slide groove 6014. When the moving block 6024 moves to both ends of the lead screw 6022, it causes the slider 6013 to vibrate violently on the slide column 6011. When the moving block 6024 moves to the center of the lead screw 6022, the slider 6013 stops vibrating. The variable stroke component 602 allows the vibration mechanism 6 to adjust the intensity of the vibration in real time according to the needs, resulting in precise control and good vibration and breaking effect, which is beneficial to improving the construction effect of the equipment.

[0042] It is worth mentioning that the oscillation assembly 603 includes a stepper motor 6031, a rotary disk 6032, a ball head seat 6033, a ball head rod 6034, a transmission rod 6035, a spring 6036, and a tamping head 6037. The stepper motor 6031 is located at the top of the top frame 6012. The rotary disk 6032 is connected to the output end of the stepper motor 6031 relative to the bottom of the top frame 6012. The ball head seat 6033 is connected to the top of the moving block 6024. One end of the ball head rod 6034 is connected to the rotary disk 6032, and the other end is connected to the ball head seat 6033. The transmission rod 6035 is symmetrically arranged on the slider 6013 relative to the bottom of the connecting frame 6021. The spring 6036 is sleeved on the transmission rod 6035, and the tamping head 6037 is connected to the bottom of the transmission rod 6035. This invention uses a stepper motor 6031 installed at the top of the top frame 6012. The stepper motor 6031 drives the rotating disk 6032 to rotate, which in turn drives the ball joint rod 6034 to rotate. The ball joint rod 6034 causes the ball joint seat 6033 and the slider 6013 to vibrate on the sliding column 6011. The slider 6013 drives the transmission rod 6035 and the tamping head 6037 to produce a vibration and breaking effect on the ground protrusions, which is beneficial to improving the construction quality of municipal roads.

[0043] Example 2: A working method for municipal road construction equipment, comprising the following steps:

[0047] S202. After the municipal road is compacted, when it is necessary to break up protrusions on the compacted road surface, turn off the reduction motor 4032. If it is necessary to break up larger or harder protrusions, first drive the servo motor 6023 to rotate the lead screw 6022. The rotation of the lead screw 6022 moves the moving block 6024 to the end. Since connecting frames 6021 are set at both ends of the slider 6013, the lead screw 6022 is inserted between the two connecting frames 6021. The servo motor 6023 drives the lead screw 6022 to rotate on the connecting frame 6021. Since the moving block 6024 is adapted to lead screw 6022. The rotation of lead screw 6022 drives moving block 6024 to slide on slide groove 6014. Moving block 6024 moves to the end. Stepper motor 6031 is set at the top of top frame 6012.
