Description

Technical Field

[0001] This utility model relates to the field of municipal construction technology, specifically to a roadbed compaction device for municipal construction. Background Technology

[0002] In municipal construction, roadbed compaction is a key step in ensuring road quality. Existing roadbed compaction devices typically use rollers to compact the roadbed in order to improve its density and stability.

[0003] However, in actual use, the pressure rollers are in direct contact with the roadbed and are easily damaged by wear and corrosion, requiring regular maintenance. Currently, most compaction devices have pressure rollers designed as a single unit. Once problems occur on the surface of the pressure roller, such as wear or cracks, the entire pressure roller usually needs to be replaced, which is costly. Utility Model Content

[0004] In view of the problems existing in the current roadbed compaction devices for municipal construction, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide a roadbed compaction device for municipal construction, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A roadbed compaction device for municipal construction includes a road roller body and an installation frame. The installation frame is fixedly installed on one side of the road roller body. A pressure roller is rotatably installed on the inner side of the installation frame. A wear-resistant sleeve is fitted on the outer wall of the pressure roller. Multiple cavities are opened inside the pressure roller. A sliding plate is slidably installed inside each cavity. An active triangular plate is slidably installed on one side of the sliding plate. A passive triangular plate is abutted against the upper side of the active triangular plate. A limiting plate is fixedly installed on the upper side of the passive triangular plate. A slot is opened on the inner wall of the wear-resistant sleeve at a position corresponding to the cavity. A through hole is opened on one side of the cavity at a position corresponding to the slot. One end of the limiting plate passes through the through hole and engages with the corresponding slot. A fixing shell is fixedly installed on the outer wall of the pressure roller at a position corresponding to the cavity. A limiting mechanism for restricting the movement of the sliding plate is provided inside the fixing shell.

[0008] Preferably, the limiting mechanism includes a limiting shell and a connecting rod. The limiting shell is slidably disposed inside the fixed shell. The connecting rod is fixedly disposed on the side of the limiting shell near the slide plate. One end of the connecting rod extends into the cavity and is fixedly connected to the slide plate. A stop is slidably disposed inside the limiting shell. A locking rod is fixedly disposed on one side of the stop. A locking hole is opened on the side wall of the fixed shell. One end of the locking rod is engaged with the locking hole. A sliding rod is fixedly disposed inside the upper side of the limiting shell. One end of the stop is movably sleeved with the sliding rod. A first spring is movably sleeved on the wall of the sliding rod. The two ends of the first spring are respectively fixedly connected to the side of the corresponding stop away from the locking rod and the inner wall of the limiting shell.

[0009] Preferably, a second spring is movably sleeved on the wall of the connecting rod, one end of the second spring is fixedly connected to the limiting shell, and the other end of the spring is fixedly connected to the inner wall of the fixed shell.

[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0014] 1. This utility model allows for the individual disassembly of the wear-resistant sleeve on the surface of the pressure roller. During roadbed compaction, the wear-resistant sleeve is in direct contact with the roadbed surface and is easily subject to wear and damage. Traditional compaction devices may require the replacement or repair of the entire pressure roller, which is complex and costly. However, this device only requires the disassembly and maintenance of the wear-resistant sleeve, without the need to treat the entire pressure roller, thus greatly saving maintenance time and costs.

[0015] 2. This utility model allows for the disassembly of the wear-resistant sleeve through simple unlocking and pulling of the limiting shell; during installation, simply put the wear-resistant sleeve on, push the limiting shell and lock it. The entire disassembly and installation process is simple to operate, does not require complicated tools or professional skills, reduces the difficulty of maintenance, improves maintenance efficiency, and saves time and effort.

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0023] This utility model discloses a roadbed compaction device for municipal construction.

[0024] Reference Figures 1-3 A roadbed compaction device for municipal construction includes a roller body 1 and a mounting frame 2. The mounting frame 2 is fixedly mounted on one side of the roller body 1. A pressure roller 3 is rotatably mounted on the inner side of the mounting frame 2. A wear-resistant sleeve 4 is fitted on the outer wall of the pressure roller 3. Multiple cavities are opened inside the pressure roller 3. A sliding plate 13 is slidably mounted inside the cavity. An active triangular plate 14 is slidably mounted on one side of the sliding plate 13. A passive triangular plate 16 is abutted against the upper side of the active triangular plate 14. A limit plate 15 is fixedly mounted on the upper side of the passive triangular plate 16. A slot is provided on the inner wall of sleeve 4 at a position corresponding to the cavity. A through hole is provided on one side of the cavity at a position corresponding to the slot. One end of the limiting plate 15 passes through the through hole and engages with the corresponding slot. The cross-sections of the limiting plate 15 and the through hole are both rectangular, which allows the limiting plate 15 to slide stably. A third spring 17 is fixedly provided on the upper surface of the passive triangular plate 16. The upper side of the third spring 17 is fixedly connected to the inner wall of the cavity, which facilitates the reset of the passive triangular plate. A fixing shell 5 is fixedly provided on the outer wall of the pressure roller 3 at a position corresponding to the cavity.

[0025] Reference Figures 1-3The fixed housing 5 has a limiting mechanism inside to restrict the movement of the sliding plate 13. The limiting mechanism includes a limiting housing 6 and a connecting rod 11. The limiting housing 6 is slidably disposed inside the fixed housing 5. The connecting rod 11 is fixedly disposed on the side of the limiting housing 6 near the sliding plate 13. One end of the connecting rod 11 extends into the cavity and is fixedly connected to the sliding plate 13. The longitudinal section of both the sliding plate 13 and the cavity is rectangular, so that the sliding plate 13 cannot rotate, that is, it can slide stably. A stop 7 is slidably disposed inside the limiting housing 6. A locking rod 10 is fixedly disposed on one side of the stop 7. The side wall of the fixed housing 5 has an opening There is a locking hole, and one end of the locking rod 10 is engaged with the locking hole. A sliding rod 8 is fixedly installed inside the upper side of the limiting shell 6. One end of the stop block 7 is movably sleeved with the sliding rod 8. A first spring 9 is movably sleeved on the rod wall of the sliding rod 8. The two ends of the first spring 9 are respectively fixedly connected to the side of the corresponding stop block 7 away from the locking rod 10 and the inner wall of the limiting shell 6. A second spring 12 is movably sleeved on the rod wall of the connecting rod 11. One end of the second spring 12 is fixedly connected to the limiting shell 6, and the other end of the second spring 12 is fixedly connected to the inner wall of the fixed shell 5, so that the limiting shell 6 cannot rotate, that is, it can slide stably.

[0026] In this invention, during normal operation of roadbed compaction, the roller body 1 moves the mounting frame 2, and the roller 3, which is rotatably mounted inside the mounting frame 2, rotates accordingly. The wear-resistant sleeve 4, fitted on the outer wall of the roller 3, directly contacts the roadbed surface to compact the roadbed. When the wear-resistant sleeve 4 needs to be disassembled for maintenance, the limiting mechanism is first unlocked by pulling the stop block 7 away from the locking hole, causing the locking rod 10 to disengage from the locking hole. At this time, the first spring 9 is compressed, and since the locking rod 10 is no longer locked in the locking hole... Next, the limiting shell 6 can slide within the fixed shell 5 under the elastic force of the second spring 12. Pulling the limiting shell 6 causes the sliding plate 13 to slide within the cavity via the connecting rod 11. Because both the sliding plate 13 and the cavity have rectangular longitudinal sections, the sliding plate 13 can only slide stably without rotating. As the sliding plate 13 slides, the active triangle 14 moves accordingly and no longer applies an upward thrust to the passive triangle 16. Under the elastic force of the third spring 17, the passive triangle 16 moves downward and resets, causing the limiting plate 15 to move out of the slot in the inner wall of the wear-resistant sleeve 4. After all the limit plates 15 have exited the slots, the connection between the wear-resistant sleeve 4 and the pressure roller 3 is released. At this point, the wear-resistant sleeve 4 can be easily removed from the pressure roller 3 for maintenance. After maintenance of the wear-resistant sleeve 4 is completed, the installation operation is performed. The wear-resistant sleeve 4 is placed on the outer wall of the pressure roller 3, aligning the slot on the inner wall of the wear-resistant sleeve 4 with the through hole on the pressure roller 3. The limit shell 6 is pushed, causing the sliding plate 13 to slide in the opposite direction within the cavity via the connecting rod 11. The active triangular plate 14 on the sliding plate 13 again abuts against the passive triangular plate 16. As the active triangle plate 14 moves, it pushes the passive triangle plate 16 upward, compressing the third spring 17. The passive triangle plate 16 moves upward, causing the limiting plate 15 to pass through the through hole and insert into the slot in the inner wall of the wear-resistant sleeve 4, thus achieving the initial connection between the wear-resistant sleeve 4 and the pressure roller 3. Then, the stop block 7 is released, the first spring 9 returns to its original state, and the stop block 7 is pushed to make the locking rod 10 insert into the locking hole in the side wall of the fixed shell 5 again, fixing the limiting shell 6 in the fixed shell 5, thereby restricting the movement of the slide plate 13, completing the installation of the wear-resistant sleeve 4, and allowing the compaction device to continue to be used.

[0027] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
