DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] In order to solve the technical problems of manual cleaning of the raised parts of the roadbed, which is cumbersome, and the tediousness of transporting other machinery to clean it, such as Figure 1-Figure 15 As shown, the following preferred technical solutions are provided: The high fill roadbed compaction device comprises a roller body 1 and a fixed frame 2 fixedly arranged on the roller body 1, a roller 3 is rotatably arranged on the fixed frame 2, the fixed frame 2 is used to support and limit the roller 3 and other components, and a vibration mechanism is arranged inside the roller 3, the vibration mechanism can generate vibration, and when the roller 3 compacts the roadbed, it cooperates with the vibration mechanism to achieve compaction while vibrating, so that the compaction efficiency is higher and the effect is better.

[0024] A mounting assembly 4 is also rotatably provided on the fixed frame 2, a pair of brake assemblies 5 are provided on the mounting assembly 4, and a mounting frame 6 is commonly provided on the two brake assemblies 5. Through the setting of the brake assembly 5, it is possible to control whether the mounting frame 6 and the components on the mounting frame 6 can slide on the mounting assembly 4. A pair of positioning assemblies 7 are fixedly provided on the mounting frame 6. When the mounting frame 6 and the components on the mounting frame 6 are rotated to a suitable position on the mounting assembly 4, the positioning assembly 7 is started to operate, so that the positioning assembly 7 is pressed against the grinding wheel 3, thereby realizing the positioning of the mounting frame 6 and the components on the mounting frame 6.

[0025] The first crushing assembly 8 and the second crushing assembly 9 are slidably mounted on the mounting frame 6, respectively, for crushing the raised part of the roadbed. A pair of gears are also rotatably mounted on the mounting frame 6, and the gears are respectively meshed and connected with the first crushing assembly 8 and the second crushing assembly 9. A pair of telescopic assemblies 10 and a plurality of pairs of hydraulic push rods 20 are also fixedly mounted on the side walls of the mounting frame 6, respectively. The output ends of the telescopic assemblies 10 are fixedly connected with the first crushing assembly 8. When the raised part of the roadbed is crushed by using the first crushing assembly 8 and the second crushing assembly 9, the hydraulic push rods 20 are started to extend, and the front end of the roadbed compacting device is slightly lifted. At this time, the first crushing assembly 8 and the second crushing assembly 9 are synchronously lifted slightly upward. At the same time, the telescopic component 10 is started to extend. During the extension process, the telescopic component 10 will drive the first crushing component 8 to move toward one side of the installation frame 6. Since the gears are respectively meshed and connected with the first crushing component 8 and the second crushing component 9, it means that when the first crushing component 8 moves, under the action of the gears, the second crushing component 9 will move in the opposite direction synchronously, thereby pushing the debris after the roadbed protrusion is crushed to the two sides of the installation frame 6, which can prevent the debris from accumulating nearby after the protrusion is crushed, and causing the roadbed to protrude after compaction again. When the cleaning is completed, the telescopic component 10 drives the first crushing component 8 and the second crushing component 9 to reset, and the hydraulic push rod 20 is reset synchronously for the next use.

[0026] The mounting assembly 4 includes a mounting plate 1 41 and a mounting plate 2 42 which are respectively rotatably mounted on the fixed frame 2. The mounting plate 1 41 and the mounting plate 2 42 are symmetrically arranged, and an annular groove 43 is respectively provided on the mounting plate 1 41 and the mounting plate 2 42. The annular groove 43 on the mounting plate 1 41 and the annular groove 43 on the mounting plate 2 42 are respectively provided with a brake assembly 5. The annular groove 43 is used to limit the brake assembly 5. A plurality of teeth 44 are also fixedly mounted on the mounting plate 1 41. A motor 45 is fixedly mounted on the side wall of the fixed frame 2. The motor 45 is used to provide power output. The output shaft of the motor 45 is arranged through the side wall of the fixed frame 2. A driving gear 46 is fixedly connected to the end of the output shaft of the motor 45. The driving gear 46 is meshed with the teeth 44. When the motor 45 is running, it can drive the mounting plate 1 41 to rotate through the driving gear 46 and the teeth 44.

[0027] The brake assembly 5 includes a slide seat 51 slidably mounted in the inner cavity of the annular groove 43, and a special-shaped chamber 52 is opened inside the slide seat 51. An electric push rod 53 is fixedly mounted on the top wall of the vertical section of the special-shaped chamber 52, and a connecting piece 54 is fixedly mounted on the output end of the electric push rod 53. A pair of brake pads 55 are symmetrically slidably mounted on the inner wall of the horizontal section of the special-shaped chamber 52. The brake pads 55 and the connecting piece 54 are movably connected through a connecting rod 56. Fig.10 As shown, when the brake assembly 5 needs to stop in the inner cavity of the annular groove 43, the electric push rod 53 is started to drive the connecting piece 54 to move downward. During the downward movement of the connecting piece 54, the brake pad 55 will be pushed to extend to the outside of the special-shaped chamber 52 through the connecting rod 56 until the brake pad 55 is tightly against the side wall of the inner cavity of the annular groove 43, and the braking effect can be achieved. Conversely, when the electric push rod 53 drives the connecting piece 54 to reset upward, the connecting piece 54 will pull the brake pad 55 into the interior of the special-shaped chamber 52 through the connecting rod 56, so that the brake pad 55 is separated from the side wall of the inner cavity of the annular groove 43. At this time, the braking effect is lost.

[0028] The mounting frame 6 comprises a U-shaped frame 61 fixedly mounted on the side wall of the slide seat 51 , and through sliding grooves 62 are symmetrically formed on both side outer walls of the horizontal section of the U-shaped frame 61 .

[0029] The positioning assembly 7 includes an electric push rod 71 fixedly mounted on the inner wall of the U-shaped frame 61, and the output end of the electric push rod 71 is fixedly connected to a top plate 72. When the electric push rod 71 is extended and drives the top plate 72 to press against the side wall of the grinding wheel 3, the positioning effect can be achieved. At this time, the braking effect between the brake assembly 5 and the annular groove 43 is released, which makes the U-shaped frame 61 and other components on the U-shaped frame 61 rotate synchronously with the grinding wheel 3.

[0030] The first crushing assembly 8 and the second crushing assembly 9 are respectively provided with a plurality of spikes.

[0031] Specifically, in the initial state, the brake assembly 5 can play a braking effect on the mounting assembly 4. When a bulge appears on the roadbed, the motor 45 is started. The motor 45 drives the mounting plate 1 41 to rotate through the active gear 46 and the teeth 44. Since the U-shaped frame 61 is fixedly mounted on the two slides 51, when the mounting plate 1 41 rotates, the mounting plate 2 42 will also synchronously follow the mounting plate 1 41 to rotate. During the rotation of the mounting plate 1 41, the brake assembly 5 on the first U-shaped frame 61 will drive the first U-shaped frame 61, the positioning assembly 7, the first crushing assembly 8 and the second crushing assembly 9 to rotate synchronously. When it rotates to a suitable position, the electric push rod 2 71 on the first U-shaped frame 61 is started to extend and drive the top plate 72 to press against the side wall of the grinding wheel 3, thereby realizing the positioning of the first U-shaped frame 61, the positioning assembly 7, the first crushing assembly 8 and the second crushing assembly 9. At the same time, the first U-shaped frame 61 The brake assembly 5 is operated to release the braking effect between the brake assembly 5 and the annular groove 43. At this time, the roller body 1 drives the roller 3 to rotate forward. During the rotation of the roller 3, the brake assembly 5, the first U-shaped frame 61, the first crushing assembly 8 and the second crushing assembly 9 are driven to rotate synchronously on the mounting plate 41 through the positioning assembly 7 on the first U-shaped frame 61. When the first crushing assembly 8 and the second crushing assembly 9 on the first U-shaped frame 61 are directly below the roller 3, the roller body 1 no longer drives the roller 3 forward. At this time, vibration is generated through the excitation mechanism, and the first crushing assembly 8 and the second crushing assembly 9 are driven to vibrate together. The first crushing assembly 8 and the second crushing assembly 9 can quickly crush the raised parts of the roadbed during vibration. Since the first crushing assembly 8 and the second crushing assembly 9 are respectively provided with a plurality of spurs, the crushing speed can be accelerated and the crushing effect can be improved. When the crushing is to continue forward, the electric push rod 2 71 on the second U-shaped frame 61 extends and drives the top plate 72 to press against the side wall of the roller 3 to achieve the positioning effect. The brake assembly 5 on the second U-shaped frame 61 releases the braking effect between the mounting plate 1 41, and the roller body 1 continues to drive the roller 3 forward. When the roller 3 passes over the first crushing assembly 8 and the second crushing assembly 9 on the first U-shaped frame 61 and presses the first crushing assembly 8 and the second crushing assembly 9 on the second U-shaped frame 61 into the bottom, the roller body 1 stops driving the roller 3 forward. At this time, the electric push rod 2 71 on the first U-shaped frame 61 shortens and drives the top plate 72 to disengage. The grinding wheel 3 causes the positioning assembly 7 to lose its positioning effect. Then, the brake assembly 5 on the first U-shaped frame 61 restores the braking effect with the mounting plate 41. At the same time, the motor 45 is started. The motor 45 drives the mounting plate 41 to rotate through the driving gear 46 and the teeth 44. During the rotation of the mounting plate 41, the brake assembly 5 on the first U-shaped frame 61 drives the first U-shaped frame 61 and the positioning assembly 7, the first crushing assembly 8 and the second crushing assembly 9 on the first mounting frame 6 to rotate to the position of the second U-shaped frame 61 to replace the position of the second U-shaped frame 61. This cycle can achieve continuous forward crushing.

[0032] Through the above settings, there is no need for manual cleaning, nor the need to transport other professional equipment for cleaning, no waiting, high construction efficiency, and it is more flexible to use. Under normal circumstances, it can be used as a separate compaction device. When encountering roadbed protrusions, it can also play a crushing role, and when encountering large-area roadbed protrusions, it can also achieve continuous crushing.

[0033] When the crushing work is completed, the roller body 1 drives the roller 3 forward until the first crushing assembly 8 and the second crushing assembly 9 on the two U-shaped frames 61 are not at the bottom of the roller 3. At this time, the positioning assemblies 7 on the two U-shaped frames 61 are separated from the roller 3, so that the positioning assemblies 7 lose their positioning effect, and then the brake assemblies 5 on the two mounting frames 6 restore the braking effect between the mounting assembly 4, and then start the motor 45. The motor 45 drives the mounting plate 1 41 to rotate through the driving gear 46 and the teeth 44 until the mounting plate 1 41 restores the two mounting frames 6 and the components on the two mounting frames 6 to their original positions. The motor 45 stops running for next use. Since the motor 45 has a braking function, it can prevent the two mounting frames 6 and the components on the two mounting frames 6 from sliding on the mounting plate 1 41 when the crushing work is not performed, thereby not affecting the subsequent compaction work.

[0034] In order to solve the technical problem that after the raised part of the roadbed is crushed, the debris is still accumulated nearby, and after compaction again, it may cause the roadbed to bulge. Figure 11-13 As shown, the following preferred technical solutions are provided: The first crushing assembly 8 includes a first slide plate 81 slidably mounted on the U-shaped frame 61 , a pair of racks 82 are symmetrically fixedly mounted on the same side wall of the first slide plate 81 , and a plurality of spurs are fixedly mounted on the outer side wall of the first slide plate 81 .

[0035] 8. The high fill roadbed compacting device according to claim 7 is characterized in that: the member 9 comprises a second slide plate 91 slidably mounted on the U-shaped frame 61, a pair of racks 92 are symmetrically fixedly mounted on the outer walls of both sides of the second slide plate 91, and the gears are meshedly connected with the racks 1 82 and the racks 2 92 respectively, and a plurality of spurs are fixedly mounted on the outer side wall of the first slide plate 81 of the second slide plate 91.

[0036] The telescopic assembly 10 includes an electric push rod 101 fixedly mounted on the side wall of the U-shaped frame 61 , the output end of the electric push rod 101 is fixedly connected to the side wall of the first slide plate 81 via a fixing member 102 , and the fixing member 102 is slidably arranged in the through-slide groove 62 .

[0037] The telescopic assembly 10 and the hydraulic jack 20 are respectively subjected to anti-vibration treatments with the U-shaped frame 61 to extend the service life of the telescopic assembly 10 and the hydraulic jack 20 .

[0038] Specifically, after the raised part of the roadbed is broken by using the first crushing assembly 8 and the second crushing assembly 9, the hydraulic push rod 20 is started to extend to slightly lift the front end of the roadbed compacting device. At this time, the first crushing assembly 8 and the second crushing assembly 9 are synchronously lifted slightly upward. At the same time, the electric push rod 3 101 is started to extend. During the extension process, the electric push rod 3 101 will drive the first slide plate 81 to move toward one side of the U-shaped frame 61. Since the gears are respectively meshed with the rack 1 82 and the rack 2 92, it means that when the first slide plate 81 moves, under the coordinated setting of the gear, the rack 1 82 and the rack 2 92, the second slide plate 91 will synchronously move in the opposite direction, and then Pushing the debris after the roadbed protrusion is crushed to both sides of the U-shaped frame 61 can prevent the debris from accumulating nearby after the protrusion is crushed, which will cause the roadbed to bulge after being compacted again. Since the first slide plate 81 and the second slide plate 91 are respectively provided with a plurality of thorns, in the process of pushing the debris after the roadbed protrusion is crushed to both sides of the U-shaped frame 61, the thorns act as a rake, which can spread the soil evenly on both sides of the U-shaped frame 61, further preventing the roadbed from bulging again after the debris is compacted. After the cleaning is completed, the telescopic component 10 drives the first crushing component 8 and the second crushing component 9 to reset, and the hydraulic push rod 20 is reset synchronously for next use.
