Abstract
Description
Technical Field
[0001] This invention belongs to the field of intelligent equipment technology, specifically an adjustment mechanism for a bridge deck compaction device. Background Technology
[0002] As the scale of bridge construction continues to expand, the compaction quality of components such as bridge deck pavement, abutment backfill, and bridge deck subbase directly determines the overall structural stability, traffic comfort, and long-term service life of the bridge. In the bridge deck construction phase, bridge deck compaction is a key process for controlling the density of the base layer and preventing subsequent pavement settlement, cracking, and bumps. Therefore, increasingly stringent requirements are placed on the operational accuracy, adjustment flexibility, and adaptability of compaction equipment. While conventional bridge deck compaction devices on the market can complete foundation compaction work, they still have many obvious defects in actual on-site operations, especially in terms of the structural design and performance of the adjustment mechanism. The adjustment mechanism of traditional compaction equipment has a simple structure and single function, mostly only having basic lifting and limiting functions. It cannot flexibly adjust the compaction height, levelness, and working angle according to the actual construction conditions of the bridge deck. When facing different bridge deck structures such as straight bridge decks, arched bridge decks, and bridge approach slopes, it is difficult to quickly complete the posture adaptation, which easily leads to problems such as loose contact of the compaction plates and one-sided suspended compaction, resulting in local over-compaction and local under-compaction of the bridge deck, and the overall compaction uniformity is difficult to meet the standards. Meanwhile, the existing adjustment mechanism has poor synchronous adjustment performance, and the lifting and lowering adjustment stroke on both sides is prone to deviation. During the operation, the tamping plate is prone to tilting and shifting, which not only reduces the compaction efficiency, but also easily causes squeezing damage to the asphalt surface layer and concrete bridge deck. Traditional equipment cannot accurately control the hydraulic impact force and vibration frequency, and cannot distinguish and match the compaction strength for thin-layer paved bridge decks and thick-layer backfill pads. Either the impact force is too large and damages the bridge deck structure, or the compaction energy is insufficient and cannot achieve the standard density. In addition, conventional compaction devices lack supporting edge auxiliary adjustment structures, and there are no adaptive vibration auxiliary compaction structures around the compaction plate. Compaction blind spots are easily formed at the corners of the bridge deck and construction joints, and loose fill material cannot be effectively compacted. During construction, the compaction operation generates a lot of dust, which not only carries away the fine aggregate of the bridge deck and affects the compaction effect, but also easily intrudes into the hinged moving parts of the adjustment mechanism, causing torsion spring jamming and adjustment screw corrosion and jamming, further shortening the service life of the adjustment mechanism and frequently causing adjustment failures, unstable positioning and locking and other faults.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0020] Example 1: To effectively solve the above problems, see the attached diagram in the instruction manual. Figures 1-7 As shown, an adjustment mechanism for a bridge deck compaction device is provided. The adjustment mechanism is installed inside the compaction device and connected to the compaction plate. It includes an adjustment cover 1, a height adjustment unit, and a horizontal tilt angle adjustment unit. Both the height adjustment unit and the horizontal tilt angle adjustment unit are installed inside the adjustment cover 1 and are used to detect the working height of the hammer and the working tilt angle of the compaction device. It also includes: A vibrating plate 11 is slidably connected to the tamping plate around its perimeter, and the sidewalls of the vibrating plate 11 slide up and down with the sidewalls of the tamping plate. A vibrating rod 12 is provided on the vibrating plate 11, and a vibrating tube 13 is provided at the bottom of the adjusting cover 1. The top of the vibrating rod 12 slides inside the bottom of the vibrating tube 13. The sidewall of the vibrating tube 13 has an opening, and a vibrating block 14 is slidably connected inside the vibrating tube 13 by a spring. One end of the vibrating block 14 extends out of the vibrating tube 13 and is hinged to a lever 15 by a torsion spring. The stepped sidewall of the tamping hammer in the tamping device contacts the lever 15. The spring at the top of the vibrating block 14 is connected to the top of the vibrating tube 13, and the spring at the bottom of the vibrating block 14 is connected to the top of the vibrating rod 12. The tamping plate is rotatably installed at the bottom of the tamping device, and the sidewall of the vibrating plate 11 is connected to the tamping plate by a threaded strip 16. An adjusting rod 17 is provided, with one end hinged to the side wall of the adjusting cover 1 and the other end slidably connected to an adjusting column 18 via a spring. A detection sensor in part of the horizontal tilt adjustment unit is installed between the adjusting column 18 and the adjusting rod 17. A stop plate 19 is hinged to the bottom of the adjusting column 18 and contacts the bridge surface. An adjusting rope 2 is provided between the adjusting rod 17 and the adjusting cover 1, and the adjusting rope 2 is wound around a winding shaft 21 provided on the cover 1. The winding shaft 21 is fixed to the adjusting cover 1 by a fixing member. The conventional tamping plate is movably installed and locked at the bottom of the tamping device. When the tamping device moves and descends closer to the bridge deck, the tamping plate first contacts the bridge deck. Then, as the tamping device descends, the tamping plate gradually extends into the bottom of the tamping device from bottom to top. The function of the tamping plate being movably installed at the bottom of the tamping device is to ensure that after the tamping plate contacts the bridge deck, there are no connecting parts in contact with the tamping device. After the hammer hits the tamping plate, the tamping plate vibrates independently, reducing the vibration impact on the entire tamping device. The side wall of the vibrating plate 11 is connected to the tamping plate through threaded strips 16. When the vibrating plate 11 is raised and lowered, it is restricted by the rotation of the square vibrating tube 13 and will not rotate. This allows the vibrating plate 11 to move up and down during the interval between impacts, causing the threaded strips 16 to move up and down. The threaded strips 16, which are distributed in a ring around the tamping plate, rise and cause the tamping plate to rotate in the forward direction. When the threaded strips 16 descend, they cause the tamping plate to rotate in the reverse direction. This process of raising and lowering the threaded strips 16 causes the tamping plate to rotate in both directions. The take-up shaft 21 is fixed on the adjusting cover 1 by a conventional ratchet and pawl mechanism. For example, a ratchet is installed at one end of the take-up shaft 21 and a pawl is hinged on the adjusting cover 1. When the take-up shaft 21 is winding the adjusting rope 2, the ratchet is not engaged by the pawl and rotates normally. When the take-up shaft 21 is stationary, the adjusting rod 17 provides lateral support to the compaction device. The lateral support pressure generated pulls the adjusting rope 2 through the adjusting rod 17. The adjusting rope 2 pulls the take-up shaft 21. The take-up shaft 21 is fixed and does not rotate due to the reverse engagement of the pawl. This causes the adjusting rope 2 to straighten and tighten the adjusting rod 17. The adjusting rod 17 is tightened and supports the compaction device on the side, just like the hypotenuse of a right triangle. Specific workflow: When placing the compaction device, the worker unfolds the adjusting rod 17 to move the anti-slip plate 19 against the bridge surface. Then, the detection sensor in the horizontal tilt adjustment unit detects the verticality of the compaction device to ensure that the compaction device and the tamping plate are perpendicular to the bridge surface, reducing the degree of tilt and improving the adjustment mechanism's role in adjusting the compaction effect. When adjusting the verticality of the compaction device, the bottom of the compaction device is placed on the bridge surface through the tamping plate. If the compaction device tilts to the left, the worker rotates the nut on the left side of the compaction device, causing the adjusting column 18 on the left side to extend out of the adjusting rod 17, pushing the compaction device to the right. Then, the worker rotates the nut on the right side, causing the adjusting column 18 on the right side to retract. Combined with the rightward swing of the compaction device, precise straightening can be achieved, greatly reducing the error of manual adjustment, speeding up the installation and debugging efficiency of the device, and thus improving the overall compaction operation efficiency. Furthermore, the worker rotates each winding shaft 21 to tighten the adjusting rope 2 according to a fixed winding length. The adjusting rope 2 pulls the adjusting rod 17 slightly towards the compaction device to tighten the support, improving the stability of the compaction device during operation and thus enhancing the effectiveness of the adjusting mechanism. Some of the detection sensors in the horizontal tilt adjustment unit are installed between the adjusting column 18 and the adjusting rod 17, including displacement sensors. These displacement sensors can monitor the extension and retraction of the adjusting columns 18 on the left and right sides of the compaction device, providing adjustment data to assist the worker in straightening the compaction device. Combined with the horizontal tilt adjustment unit to detect the overall verticality of the compaction device, the ease of use is further improved, allowing the adjusting device to speed up the installation of the compaction device and thus improve the compaction work efficiency. Moreover, the anti-slip plate 19, with its large-area flat contact with the bridge surface, increases the support area and improves support stability. At the same time, the large-area contact of the anti-slip plate 19 with the bridge surface can prevent the anti-slip plate 19 from sinking into the bridge surface due to the support weight, thus preventing the compaction device from tilting. It can be adapted to soft base surfaces such as soft soil cushion layers and newly paved bridge surfaces, preventing the support point from sinking and reducing the pressure damage to the bridge surface. Since the tamping plate is movably installed at the bottom of the compaction device, there are no connecting parts in contact with the compaction device after the tamping plate contacts the bridge surface. After the hammer hits the tamping plate, the tamping plate vibrates independently, reducing the vibration impact on the entire compaction device. The impact of vibration on the adjusting rod 17 caused by the compaction work is reduced, thereby reducing the impact of vibration on the tilt support of the compaction device. Workers can also add conventional vibration reduction parts such as dampers at the connection between the adjusting rod 17 and the side wall of the adjusting cover 1 to further improve the vibration reduction effect of the adjusting rod 17. During the compaction process, the hammer descends past the deflector block 15. The deflector block 15 does not descend but instead compresses the torsion spring and swings past the hammer. The hammer continues to descend and strikes the tamping plate, which compacts the bridge surface. Then, the hammer rises, and the deflector block 15 rises unrestricted, causing the vibrating block 14 to rise along with the stepped sidewall of the hammer. The spring above the vibrating block 14 is compressed and stores energy, while the spring below pulls the vibrating plate 11 upward. The rising vibrating plate 11 drives the tamping plate to rotate during the impact interval through the threaded strip 16. The tamping plate rotates on the bridge surface, and the friction removes the gravel and other impurities attached to the bottom contact surface of the tamping plate, improving the cleanliness of the tamping plate and thus improving the compaction effect. This prevents the compacted surface of the bridge surface from being affected by protruding gravel, which could affect the compaction structure or cause frequent unevenness. As the threaded bar 16 rises, it causes the tamping plate to rotate forward; as the threaded bar 16 falls, it causes the tamping plate to rotate in the opposite direction. This process of rising and falling of the threaded bar 16 causes the tamping plate to rotate in both directions. During the rotation, the tamping plate will rotate slightly, allowing different parts of the tamping plate to alternately contact the bridge deck during multiple forward and reverse rotations. For example, the left part of the tamping plate can be gradually rotated to the right part to adjust the tamping plate to evenly compact the bridge deck. This effectively avoids local deformation caused by prolonged work of the tamping plate, which would lead to over-compaction in some areas of the bridge deck. It ensures that the overall compaction degree of the bridge deck is consistent, improves the flatness and structural stability of the bridge deck, and thus improves the adjustment effect of the bridge deck compaction. Furthermore, for compaction operations on complex conditions such as sloping bridge decks and arch surfaces, the adjusting rope 2 is fixed by a ratchet and pawl mechanism, which allows the adjusting rod 17 to remain taut and supported for a long time, just like the supporting effect of the hypotenuse of a right triangle. This effectively improves the lateral stability of the compaction device during operation and prevents the device from shaking or slipping during high-frequency compaction. Furthermore, the tamping hammer drives the vibrating plate 11 to rise and vibrate. The vibrating plate 11 in the forward direction of the tamping plate vibrates and strikes the bridge surface to be compacted. This can pre-vibrate and level the loose paving material and backfill layer in advance, break up large lumps of material, reduce the gaps between particles in the soil layer, and expel excess air in advance, making the material arrangement in the area to be compacted more regular and dense. This can reduce the settlement amplitude during the subsequent main tamping, making the compaction settlement more uniform and controllable, and can also gather the loose sand and gravel mixture on the bridge surface in advance to prevent the material from scattering and being lost. The vibrating plate 11 behind the tamping plate vibrates and taps the already compacted bridge surface. After the bridge surface is tamped, the soil is very prone to elastic rebound, creating tiny gaps again. The vibrating plate 11 behind it continuously vibrates and taps with small amplitude, which can firmly lock the already formed dense structure and effectively counteract the tendency of soil rebound. At the same time, it can also repair the gap between the tamping plate and the vibrating plate 11, or the slight indentations and uneven marks left by the slight deformation of the tamping plate, smooth out the protruding aggregate on the surface of the bridge surface, improve the flatness of the bridge surface, and make the formed bridge surface smoother. The vibrating plates 11 on both sides of the tamping plate beat the bridge deck on both sides of the area being tamped, which can fill in the compaction gaps at the edges, construction joints, and corners of the bridge deck, ensuring uniform density across the lateral range of the bridge deck. Furthermore, the vibrating plates 11 on both sides and in front work together to prevent the material being compacted and squeezed in the middle from shifting to the sides and in front, firmly locking the compaction area and preventing material shortages or edge collapses. For weak areas such as bridge deck expansion joints and panel splicing gaps, the side vibrating plates 11 can achieve flexible compaction and filling, sealing the internal voids of the gaps and enhancing the overall sealing of the bridge deck, thereby improving the compaction effect of the bridge deck.
[0021] Example 2: Based on Embodiment 1, an assembly plate 22 is slidably mounted on the bottom of the vibrating plate 11. The bottom surface of the assembly plate 22 is in contact with the bridge surface, and the bottom curvature of the assembly plate 22 closer to the forward direction of the tamping plate is greater than that of the assembly plate 22 farther away from the forward direction of the tamping plate. A detection strip 23 is provided on one side of the vibrating plate 11. The detection strip 23 is farther away from the forward direction of the tamping plate, and counterweights are evenly provided on the detection strip 23. The bottom of the detection strip 23 is in contact with the bridge surface. A storage box 24 is provided on the adjusting cover 1. The storage box 24 is distributed on the top of the anti-slip plate 19 and the vibrating plate 11, and the storage box 24 is located in the forward direction of the tamping plate. The storage box 24 stores the compacted material. Valves 25 are evenly provided on the side wall of the storage box 24. Multiple spray holes on the storage box 24 are closed and opened through the valves 25. The side wall of the vibration plate 11 is slidably connected to an assembly rod 26 by a spring. One side of the assembly rod 26 is inclined and locked to the side of the assembly plate 22. A cleaning brush is provided on the assembly rod 26. A covering film 27 is provided between the vibrating plate 11 and the stop plate 19, and the covering film 27 is located in the forward direction of the tamping plate. The bottom of the covering membrane 27 is provided with a liquid storage bladder 28, and the bottom of the liquid storage bladder 28 is evenly provided with closed holes, which cover the forward direction of the ramming plate. A pneumatic cap is provided on one side of the liquid storage bladder 28 to balance the internal pressure of the liquid storage bladder 28. The covering membrane 27 is triangular and the tip is connected to the anti-slip plate 19. Specific workflow: After installing vibrating plates 11 around the tamping plate, the working area of the tamping plate increases. If encountering a curved bridge surface, the increased tamping working area may cause a certain curvature in the tamping area. If a flat tamping plate is used to contact the curved bridge surface, it will cause the bridge surface to bulge, affecting the flatness. Therefore, when tamping the bridge surface, the assembly plate 22 at the bottom of the vibrating plate 11 is moved laterally and removed from the side, and replaced with an assembly plate 22 with a flat bottom, so that the assembly plate 22 matches the flat bridge surface. When tamping the curved bridge surface, the flat assembly plate 22 is removed and replaced with one with a curved bottom, so that the assembly plate 22 adapts to the curved bridge surface and improves the flatness of the bridge surface tamping. The bottom curvature of the assembly plate 22 closer to the direction of the tamping plate is greater than that of the assembly plate 22 farther away from the direction of the tamping plate. When moving forward, the assembly plate 22 with a larger curvature in the direction of the tamping plate will contact the curved bridge surface first. It can make contact with the curved surface of the bridge surface without bumping against the protruding parts of the bridge surface. This avoids the problem of local bulging and aggregate squeezing and accumulation caused by the strong pressure of the flat plate surface on the curved bridge surface. It also reduces the defects of high and low misalignment and allows the tamping action of the vibrating plate 11 to be carried out completely along the curvature of the bridge surface, thus improving the compaction effect of the bridge surface. Furthermore, the large-arc assembly plate 22 at the front gently pats the uncompacted arc-shaped area, smoothing out the loose paving material along the curved surface and completing the initial shaping of the bridge deck area to be compacted; the small-arc assembly plate 22 at the rear pats the area that has been pre-compacted, and performs secondary compaction with a nearly gentle arc, gradually reducing the curvature of the bridge deck and repairing any protrusions, so that the arc-shaped bridge deck can smoothly transition from the natural slope to the standard construction curved surface; By setting up the detection strip 23, when replacing the assembly plate 22, the detection strip 23 is attached to the bridge surface by the heavy pressure of the counterweight block, providing workers with a visual reference for the type of assembly plate 22 to be replaced, which facilitates the replacement of the assembly plate 22, reduces the intervention of manual experience, forms a template or standard for the replacement of the assembly plate 22, improves the efficiency of tamping adjustment, and thus improves the tamping efficiency. By setting up a storage box 24, and the valve 25 on the storage box 24 is a simple valve that is conventionally used to seal the storage box 24, when the vibrating plate 11 vibrates and the anti-slip plate 19 is affected by vibration, the storage box 24 vibrates up and down, which drives the internally stored material to vibrate. When the material vibration descends, it squeezes open the valve 25 and sprinkles it onto the bridge surface to be compacted, thus achieving autonomous material sprinkling without the need for additional motors, pumps or other power components. Storage box 24 can store various construction auxiliary materials. For example, sprinkling water can pre-wet the dry and loose subbase, reduce dust during compaction, and soften soil particles, making the material easier to compress and compact. Sprinkling soil stabilizer can pre-soak the base soil, allowing it to quickly solidify and take shape after compaction, effectively reducing soil rebound. Sprinkling stone chips, fine sand, and other aggregates can pre-fill gaps and voids in the bridge deck base and optimize particle size distribution. Sprinkling a small amount of dry cement powder can also improve the overall bonding strength and structural stability of the bridge deck base. After the materials come into contact with the bridge deck, the vibrating plate 11 can carry out compaction operations, pressing the materials into the interior of the bridge deck to improve the effect. By setting up the assembly rod 26, when installing the assembly plate 22, the inclined surface of one side of the assembly plate 22 is inserted into the gap between the assembly rod 26 and the vibrating plate 11, and then inserted to the bottom of the vibrating plate 11. The assembly rod 26 cleans the assembly plate 22 with a cleaning brush. After the assembly plate 22 is completely inserted into the vibrating plate 11, the assembly rod 26 rises and gets stuck on the inclined surface of the other side of the assembly plate 22 due to the influence of the spring. The worker can then tighten the bolts to fix it. After the assembly plate 22 has been working for a period of time, impurities such as base material may adhere to the bottom of the assembly plate 22. After the worker loosens the fixing effect of the assembly rod 26, the assembly plate 22 can be pulled back and forth, and the bottom of the assembly plate 22 can be cleaned with a cleaning brush to improve the cleanliness of the assembly plate 22, thereby improving the leveling effect of the pre-compaction and thus improving the flatness of the compaction. Furthermore, during the preparation work, the vibrating plate 11 drives the covering film 27 to vibrate. One end of the covering film 27 connected to the vibrating plate 11 moves up and down, while the other end connected to the stop plate 19 is fixed. This allows the covering film 27 to repeatedly rise and fall, compressing the air in the area to be compacted, accelerating the airflow and blowing away the dust on the bridge surface. This prevents the dust from affecting the effectiveness of the material spreading, similar to the covering film 27 patting the bridge surface. The dust on the bridge surface is patted and blown away, improving the cleanliness of the bridge surface. While the covering film 27 is vibrating, the workers control the storage box 24 to prevent the material from spreading. During material spreading, the covering membrane 27 and the storage box 24 vibrate together. The covering membrane 27 drives the liquid storage bladder 28 to vibrate. The water and other solvents inside the liquid storage bladder 28 squeeze the closed hole. A conventional pressure valve is installed in the closed hole, which opens when pressure is applied and closes when pressure is applied. Water is evenly spread from below the covering membrane 27 onto the bridge surface, mixing with the spread material and entering the bridge surface, improving the penetration effect of the spread material, thereby improving the effect of the spread material and thus improving the compaction effect. When the worker tightens the air pressure cap, the internal pressure of the liquid storage bladder 28 cannot be replenished by absorbing outside air, so the water inside cannot flow out or the flow out is reduced. When the air pressure cap is unscrewed, the liquid storage bladder 28 can absorb air through the air pressure cap to replenish the internal pressure, and the water can flow out smoothly.
[0022] Example 3: Based on Embodiment 2, the bottom of the storage box 24 is provided with a slider 29, one of the sliders 29 of the storage box 24 is slidably connected to the anti-slip plate 19 by a spring, and the other slider 29 is connected to the vibration plate 11 by a spring; The slider 29 is provided with a roller 3, and the outer periphery of the roller 3 contacts the bridge surface; The covering film 27 has an opening, and a covering sheet 31 is attached to the opening of the covering film 27. The edge of the covering sheet 31 is provided with an elastic strip 32. Specific workflow: By setting slider 29, when vibrating plate 11 moves forward, it drives slider 29 to move and scrape across the bridge surface, which plays a role in leveling the bridge surface in advance, thereby improving the flatness of the bridge surface to be compacted, and thus improving the compaction effect of the bridge surface. By setting up roller 3, when the compaction device moves forward, roller 3 rolls the bridge surface in advance to flatten the protrusions such as gravel on the bridge surface, thereby improving the flatness of the bridge surface and thus improving the flatness of the bridge surface after compaction. By setting up a cover plate 31, which is connected to the cover film 27 via Velcro, when it is necessary to squeeze air to blow away dust, the cover plate 31 sticks to the cover film 27, so that the holes on the cover film 27 are covered and formed as a whole, increasing the cleaning effect. When it is necessary to spray water, the cover plate 31 is pulled away from the cover film 27 by pulling the elastic strip 32, exposing the holes on the cover film 27, so that the vibration of the cover film 27 will not squeeze air, causing the water mist sprayed from the liquid reservoir 28 to be evenly sprayed on the bridge surface, improving the effect. By setting up the elastic strip 32, which is attached to the covering membrane 27 via the covering sheet 31, the elastic strip 32 provides elastic support to the covering membrane 27. When the covering membrane 27 vibrates, the elastic strip 32 can bend repeatedly, which improves the effect of the covering membrane 27 in squeezing air to blow away dust and improves the cleanliness of the area to be compacted on the bridge deck.
[0023] Example 4: Based on Embodiment 3, the elastic bar 32 is provided with a pull rope 33, one end of which is fixed to the adjusting rod 17; A scraper is slidably connected to one side of the vibrating plate 11, and the scraper contacts the bottom of the tamping plate. Specific workflow: By setting up the pull rope 33, the worker pulls the elastic bar 32 and lifts the cover plate 31 by pulling the pull rope 33. Then, after the pull rope 33 is knotted and fixed on the adjusting rod 17, the cover plate 31 is erected in front of the material to block the wind and avoid the influence of the wind on the bridge when spreading the material and spraying water mist. By setting the push plate 34, after the tamping plate has been working for a period of time, the tamping plate is left to stand still and slightly lifted off the ground. The worker releases the scraper and pushes the scraper to move laterally back and forth. The scraper repeatedly scrapes the bottom of the tamping plate, removing gravel and impurities, restoring the flatness of the bottom of the tamping plate, thereby improving the flatness of the bridge deck and thus improving the tamping effect of the bridge deck.
