Description

Technical Field

[0001] The present invention relates to the technical field of engineering construction machinery, and in particular to a highway roadbed crushing and leveling integrated machine and method based on an energy-saving motor. Background Art

[0002] After highway construction is completed, the roadbed may become uneven or partially protruding due to factors such as geological conditions, construction techniques, and material quality. An uneven roadbed can affect the smoothness and driving comfort of the highway, increase vehicle resistance, reduce driving speeds, and even cause traffic accidents. Protruding roadbeds, on the other hand, can cause damage such as scratches and collisions to vehicles, seriously threatening driving safety.

[0003] To solve these problems, it is necessary to crush the uneven roadbed and the protruding roadbed to achieve the flatness and height required by the design. Traditional roadbed crushing methods usually use a single crushing device, such as a breaker hammer, crusher, etc. These devices have many limitations when dealing with different types and degrees of roadbed problems. For example, for uneven roadbeds, it is difficult to accurately control the crushing depth and range with a single crushing device, which can easily cause the crushed roadbed to be inconsistent with the roadbed height standard.

[0004] At the same time, when using direct impact crushing to crush the protruding roadbed, the vibration will be transmitted on the roadbed, affecting the quality of the entire roadbed and causing the roadbed to become loose.

[0005] In response to the above problems, the present invention document proposes a highway roadbed crushing and leveling integrated machine and method based on an energy-saving motor. Summary of the Invention

[0006] The present invention provides a highway roadbed crushing and leveling integrated machine and method based on an energy-saving motor, which solves the shortcomings of the existing roadbed crushing equipment in that it is difficult to accurately control the crushing depth and range, and it is easy to cause vibration transmission and lead to loosening of the roadbed.

[0007] The present invention provides the following technical solutions:

[0008] A highway roadbed crushing and leveling machine based on an energy-saving motor, comprising:

The adjusting frame is slidably connected to the connecting frame, the reciprocating screw is rotatably installed in the adjusting frame, and is engaged with the transmission shaft through a transmission assembly for transmission. A slip ring is sleeved on the reciprocating screw, and the slip ring is connected to a mounting rod through a connecting plate. The bottom end of the mounting rod is fixed to a support plate, and a plurality of crushing assemblies are installed at the bottom of the support plate;

[0013] The moving mechanism includes a second electric push rod, the output end of which is connected to the adjustment frame and is used to adjust the height of the crushing assembly;

[0014] The energy-saving drive motor drives the annular knife to rotate and cut the roadbed, the transmission assembly drives the reciprocating screw to rotate, so that the slip ring reciprocates along its longitudinal direction, and drives the crushing assembly to impact and crush the cut roadbed.

[0015] In a possible design, the movable frame includes four limiting rings, two connecting rods and two support rods. The limiting rings are slidably mounted on the mounting frame. The two ends of the connecting rods are fixedly connected to the corresponding limiting rings. The two ends of the support rods are fixedly connected to the two connecting rods. The output shaft of the first electric push rod is fixedly connected to the support rod through a limiting plate.

[0016] In one possible design, the transmission assembly includes a gear column fixed on the transmission shaft and a driven gear fixed on the reciprocating screw, the gear column is engaged with the driven gear, and the length of the gear column is greater than the thickness of the driven gear.

[0017] In a possible design, the adjustment frame includes a base plate, a top plate and a rectangular frame connecting the two, the base plate and the top plate are slidably connected in the connecting frame, the reciprocating screw is rotatably installed between the base plate and the top plate, the slip ring is located between the base plate and the top plate, the connecting plate passes through the sliding connection limit rod, and the two ends of the limit rod are fixed to the base plate and the top plate.

[0018] In one possible design, the crushing assembly includes a protective box, an energy-saving variable frequency motor and a crushing disk. The protective box is fixed to the top of the support plate, and the energy-saving variable frequency motor is installed in the protective box. Its output shaft passes through the connecting pipe and is connected to the crushing disk. Multiple buffer grooves are opened at the bottom of the crushing disk, and rubber pads and slidingly connected crushing teeth are arranged in the grooves.

[0019] In a possible design, the crushing disk is rotatably connected to the bottom end of the connecting pipe via a connecting ring, and the bottom of the crushing teeth extends below the crushing disk and slidably engages with the inner wall of the buffer groove.

[0021] In a possible design, the support frame is fixed to the support rod via a first fixing ring, and the connecting frame is fixed to the other support rod via a second fixing ring.

[0022] In a possible design, the mounting frame is fixedly connected to the roller via a fixing frame and an equipment frame, and the fixing frames are reinforced by fixing plates.

[0023] The method for using the highway roadbed crushing and leveling machine based on the energy-saving motor includes the following steps:

[0024] S1. First, the device is installed on the roller so that the device can move with the roller to crush the protruding roadbed part that needs to be crushed;

[0025] S2. The two first electric push rods are activated to drive the movable frame to move longitudinally along the mounting frame, thereby adjusting the height of the annular cutter according to the standard height of the roadbed measured by the total station;

[0026] S3. By starting the second electric push rod, the height of the adjustment frame can be driven to adjust through the U-shaped frame, so that the height of the multiple crushing discs can be adjusted, so that the height of the multiple crushing discs can be adjusted according to the height of the roadbed to be crushed, so that the roadbed can be impacted and crushed after the roadbed is cut;

[0027] S4. The energy-saving drive motor is started to drive the transmission shaft to rotate, thereby driving the annular cutter to rotate with the support of the cutter holder. The rotating annular cutter can cut the roadbed as the roller moves;

[0028] S5. When the gear column rotates along with the transmission shaft, it can drive the reciprocating screw to rotate under the meshing transmission action with the driven gear. When the reciprocating screw rotates, it can cooperate with the transmission of the slip ring to make the slip ring perform longitudinal reciprocating motion along the reciprocating screw. In this way, multiple crushing discs can be driven to perform longitudinal reciprocating motion through the connecting plate, the mounting rod and the supporting plate. Therefore, when the crushing disc moves downward, it can squeeze the cut roadbed sand and gravel.

[0029] S6. By starting the energy-saving variable frequency motor to drive the crushing disk to rotate, multiple crushing teeth that follow the crushing disk in a circular motion can crush the roadbed, thereby quickly crushing the roadbed. The crushed roadbed sand and gravel will fall on the rotating annular knife and knife holder. At this time, the roadbed sand and gravel can undergo centrifugal motion under the rotation of the annular knife and knife holder, and be scattered on the highway roadbed.

[0030] It should be understood that the foregoing general description and the following detailed description are exemplary only and are not restrictive of the invention.

[0031] Beneficial effects: In the present invention, the adjustment mechanism is provided, and the two first electric push rods are activated to drive the movable frame to move longitudinally along the mounting frame, so that the height of the cutting mechanism can be adjusted. In this way, the height of the cutting mechanism can be adjusted according to the standard height of the roadbed measured by the total station, so that the roadbed can be pre-cut at a specified height.

[0032] In the present invention, the cutting mechanism can be set up to drive the transmission shaft to rotate by starting the energy-saving drive motor, thereby driving the annular knife to rotate under the support of the knife holder. The rotating annular knife can cut the roadbed when moving with the roller.

[0033] In the present invention, the crushing mechanism is provided, and when the reciprocating screw rotates along with the driven gear, the reciprocating screw can be driven to move back and forth longitudinally along the reciprocating screw in cooperation with the transmission of the slip ring, thereby driving the plurality of crushing assemblies to move back and forth longitudinally through the connecting plate, the mounting rod and the supporting plate, thereby providing a driving force for the crushing assemblies to move downward repeatedly, thereby extruding and crushing the cut roadbed;

[0034] In the present invention, by setting up a moving mechanism, the height of the adjustment frame can be adjusted by starting the second electric push rod through the U-shaped frame, so that the height of multiple crushing disks can be adjusted, so that the height of multiple crushing disks can be adjusted according to the height of the roadbed that needs to be crushed, so that the roadbed can be impact-crushed after cutting.

[0035] The present invention can pre-cut the protruding roadbed according to the height of the entire roadbed, and can impact-crush the cut roadbed, so that when the roadbed is crushed, the pre-cutting method can avoid the problem of vibration transmission in the subsequent impact crushing process. At the same time, after the roadbed is crushed, the height of the entire roadbed can be kept consistent, avoiding quality problems of the roadbed. BRIEF DESCRIPTION OF THE DRAWINGS

[0049] In one embodiment: Figure 1-9 A crushing and leveling machine includes a mounting frame 2 mounted on a road roller 1. Four fixing brackets 32 are symmetrically fixed to one side of the mounting frame 2. Two longitudinally arranged fixing brackets 32 are bolted to a common fixing plate 33 on one side. A device bracket 34 is welded to one side of the fixing plate 33. The two device brackets 34 are fixedly connected to one side of the road roller 1.

[0050] like Figure 2 and Figure 3As shown, an adjustment mechanism is installed on the mounting frame 2, and the adjustment mechanism includes a movable frame connected to the mounting frame 2. The movable frame is composed of four limit rings 3, two connecting rods 4 and two support rods 5. The four limit rings 3 are slidably mounted on the mounting frame 2, and the two ends of the connecting rods 4 are fixedly connected to the corresponding limit rings 3, and the two ends of the support rods 5 are fixedly connected to the two connecting rods 4. Two mounting plates 6 are also symmetrically fixedly installed on the mounting frame 2. A first electric push rod 7 is fixedly installed on the top of the mounting plate 6. The output shaft of the first electric push rod 7 passes through the mounting plate 6, and a limit plate 8 is fixedly installed on the output shaft. The limit plates 8 are fixedly connected to the two support rods 5. By starting the two first electric push rods 7, their output shafts drive the limit plates 8 to move, thereby driving the movable frame to move longitudinally along the mounting frame 2.

[0051] like Figure 4 and Figure 5 As shown, two cutting mechanisms are symmetrically mounted on the adjustment mechanism, and the cutting mechanism includes a support frame 11.

The bottom end of the transmission shaft 13 extends to the bottom of the support frame 11. A tool holder 14 located below the support frame 11 is fixedly mounted on the transmission shaft 13 (the tool holder 14 and the transmission shaft 13 can also be connected by a friction plate clutch). An annular knife 15 is fixedly mounted on the tool holder 14. A plurality of notches 151 are provided at equal intervals on the annular knife 15 (the notches 151 can be trapezoidal notches to enhance chip removal capabilities). By starting the energy-saving drive motor 12 to drive the transmission shaft 13 to rotate, the annular knife 15 is driven to rotate with the support of the knife holder 14. The rotating annular knife 15 cuts the roadbed when it moves with the roller 1.

[0052] The present application can be used in the field of engineering construction machinery technology, and can also be used in other fields applicable to the present application.

[0053] In another embodiment: Figure 6-9Based on the above embodiment, an improved embodiment is provided: a highway roadbed crushing and leveling machine based on an energy-saving motor, which is applied to the field of engineering construction machinery technology, and further includes two crushing mechanisms mounted on the two cutting mechanisms. The crushing mechanisms include a connecting frame 17 fixedly mounted on the other side of the support frame 11. A second fixing ring 10 is fixedly mounted on the top of one side of the connecting frame 17. The second fixing ring 10 is sleeved on the support rod 5 on the other side and fixedly connected to the support rod 5 on the other side by bolts. The connecting frame 17 is connected to an adjustment frame, which includes a base plate 18, two rectangular frames 19, and a top plate 20. The base plate 18 and the top plate 20 are both slidably connected within the connecting frame 17. The rectangular frame 19 is located between the top plate 20 and the base plate 18 and is fixedly connected to the top of the base plate 18 and the bottom of the top plate 20, respectively. A reciprocating screw 21 (40Cr quenched and tempered) is mounted within the adjustment frame. The reciprocating screw 21 is rotatably connected to the top of the base plate 18, passes through the top plate 20, and is rotatably connected to the top plate 20. A transmission assembly is connected to the transmission shaft 13. The transmission assembly includes a gear column 16 fixedly mounted on the transmission shaft 13. A driven gear 29 is fixedly mounted on the reciprocating screw 21. The driven gear 29 meshes with the gear column 16, and the length of the gear column 16 is longer than that of the driven gear 29. A slip ring 22 is mounted on the reciprocating screw 21, which cooperates with the spiral groove on the reciprocating screw 21. The slip ring 22 is located between the bottom plate 18 and the top plate 20. A connecting plate 23 is fixedly mounted on one side of the slip ring 22. One side of the connecting plate 23 extends to the outside of the connecting frame 17. A limit rod 24 is slidably connected to the connecting plate 23. The top and bottom ends of the limit rod 24 are fixedly connected to one side of the top plate 20 and one side of the bottom plate 18, respectively. A mounting rod 25 is fixedly mounted on one side of the bottom of the connecting plate 23, and a support plate 26 is fixedly mounted on the bottom end of the mounting rod 25. A plurality of crushing assemblies are installed at equal intervals on the support plate 26, and the crushing assembly includes a protective box 27 fixedly installed on the top of the support plate 26, and an energy-saving variable frequency motor 35 is fixedly installed on the bottom inner wall of the protective box 27. It also includes a connecting pipe 36 fixedly installed on the bottom of the support plate 26, and the bottom end of the connecting pipe 36 is rotatably connected to a connecting ring 37, and a crushing disk 28 is fixedly installed on the bottom of the connecting ring 37. A plurality of buffer grooves are opened at equal intervals at the bottom of the crushing disk 28, and a rubber pad 38 (which can be a polyurethane elastomer) is fixedly installed in the buffer groove. Crushing teeth 39 are bonded to the bottom of the rubber pad 38, and the crushing teeth 39 slide in cooperation with the inner wall of the buffer groove. The bottom of the crushing teeth 39 extends to the bottom of the crushing disk 28, and the output shaft of the energy-saving variable frequency motor 35 passes through the connecting pipe 36 and is fixedly connected to the top center position of the crushing disk 28.As the gear column 16 rotates along with the drive shaft 13, it meshes with the driven gear 29, driving the reciprocating screw 21 to rotate. In conjunction with the slip ring 22, the slip ring 22 performs longitudinal reciprocating motion along the reciprocating screw 21. This, in turn, drives the multiple crushing assemblies through the connecting plate 23, mounting rod 25, and support plate 26, providing the crushing assemblies with a driving force to repeatedly move downward, crushing the cut roadbed. Simultaneously, the energy-saving variable-frequency motor 35 is activated to rotate the crushing disc 28. The multiple crushing teeth 39, which follow the crushing disc 28 in a circular motion, crush the roadbed. The crushed roadbed sand and gravel fall onto the rotating annular blade 15 and blade holder 14, undergoing centrifugal motion as they rotate, and are then scattered onto the highway roadbed.

[0054] like Figure 6 As shown, the crushing mechanism is also equipped with a movable mechanism for adjusting the height of the crushing mechanism. The movable mechanism includes a second electric push rod 31 fixedly mounted on the top of the connecting frame 17. The output shaft of the second electric push rod 31 extends into the connecting frame 17 and is fixedly mounted with a U-shaped frame 30. The U-shaped frame 30 is fixedly mounted on the top of the top plate 20. By activating the second electric push rod 31, the height of the adjustment frame is adjusted through the U-shaped frame 30, thereby adjusting the height of the multiple crushing discs 28.

[0055] In this technical solution, the model of the energy-saving drive motor 12 is SIMOTICSGP1LE0, and the model of the energy-saving variable frequency motor 35 is HC-KFS43. The first electric push rod 7 and the second electric push rod 31 can also be hydraulic cylinders.

[0056] The present invention also proposes a method for using a highway roadbed crushing and leveling machine based on an energy-saving motor, comprising the following steps:

[0057] S1. First, the device is installed on the road roller 1 so that the device can move with the road roller 1 to crush the protruding roadbed part that needs to be crushed;

[0058] S2. By starting the two first electric push rods 7, the movable frame can be driven to move longitudinally along the mounting frame 2, so that the height of the annular cutter 15 can be adjusted according to the standard height of the roadbed measured by the total station;

[0059] S3. By starting the second electric push rod 31, the height of the adjustment frame can be driven to adjust via the U-shaped frame 30, so that the height of the multiple crushing discs 28 can be adjusted according to the height of the roadbed to be crushed, so as to impact and crush the roadbed after cutting;

[0060] S4. The energy-saving drive motor 12 is started to drive the transmission shaft 13 to rotate, thereby driving the annular cutter 15 to rotate with the support of the cutter holder 14. The rotating annular cutter 15 can cut the roadbed as the roller 1 moves;

[0061] S5. When the gear column 16 rotates along with the transmission shaft 13, it can drive the reciprocating screw 21 to rotate under the meshing transmission action with the driven gear 29. When the reciprocating screw 21 rotates, it can cooperate with the transmission of the slip ring 22 to enable the slip ring 22 to perform longitudinal reciprocating motion along the reciprocating screw 21. In this way, the multiple crushing discs 28 can be driven to perform longitudinal reciprocating motion through the connecting plate 23, the mounting rod 25 and the supporting plate 26. Therefore, when the crushing discs 28 move downward, they can squeeze the cut roadbed sand and gravel.

[0062] S6. By starting the energy-saving variable frequency motor 35 to drive the crushing disk 28 to rotate, the multiple crushing teeth 39 that follow the crushing disk 28 to perform circular motion can crush the roadbed, thereby achieving rapid crushing of the roadbed. The crushed roadbed sand and gravel will fall on the rotating annular knife 15 and the knife holder 14. At this time, the roadbed sand and gravel can undergo centrifugal motion under the rotation of the annular knife 15 and the knife holder 14, and be scattered on the highway roadbed.

[0063] However, as is well known to those skilled in the art, the working principles and wiring methods of the first electric push rod 7 and the second electric push rod 31 are commonplace, and are conventional means or common knowledge, and will not be elaborated here. Those skilled in the art can make any selections according to their needs or convenience.

[0064] The drawings in this application are for illustrative purposes only. The sizes and shapes of the components shown are not intended to be limiting, but are merely for illustrative purposes. In actual implementation, the components may be appropriately configured and adjusted based on specific needs and actual conditions.

[0065] The above are only specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. The embodiments of the present invention and the features therein can be combined with each other unless there is a conflict. Therefore, the scope of protection of the present invention shall be based on the scope of protection of the claims.

10. The method for using the highway roadbed crushing and leveling machine based on an energy-saving motor according to any one of claims 1 to 9, characterized in that: The following steps are involved: S1. First, the device is installed on the road roller (1) so that the device can move along with the road roller (1) to crush the protruding roadbed portion that needs to be crushed; S2, by starting the two first electric push rods (7), the movable frame can be driven to move longitudinally along the mounting frame (2), thereby adjusting the height of the annular knife (15), thereby adjusting the height of the annular knife (15) according to the standard height of the roadbed measured by the total station; S3, by starting the second electric push rod (31) through the U-shaped frame (30), the height of the adjustment frame can be driven to adjust, thereby adjusting the height of the plurality of crushing disks (28), so that the height of the plurality of crushing disks (28) can be adjusted according to the height of the roadbed to be crushed, so that the roadbed can be impact-crushed after the roadbed is cut; S4, starting the energy-saving drive motor (12) to drive the transmission shaft (13) to rotate, thereby driving the annular cutter (15) to rotate with the support of the cutter holder (14), and the rotating annular cutter (15) can cut the roadbed when the roller (1) moves; S5. When the gear column (16) rotates along with the transmission shaft (13), the gear column (16) can drive the reciprocating screw (21) to rotate under the meshing transmission action with the driven gear (29). When the reciprocating screw (21) rotates, the reciprocating screw (21) can be driven by the slip ring (22) to perform longitudinal reciprocating motion along the reciprocating screw (21). Thus, the plurality of crushing discs (28) can be driven to perform longitudinal reciprocating motion through the connecting plate (23), the mounting rod (25) and the supporting plate (26). Therefore, when the crushing discs (28) move downward, the cut roadbed sand and gravel can be squeezed; S6. The energy-saving variable frequency motor (35) is started to drive the crushing disc (28) to rotate. At this time, the plurality of crushing teeth (39) that follow the crushing disc (28) to perform annular motion can crush the roadbed, thereby achieving rapid crushing of the roadbed. The crushed roadbed sand and gravel will fall on the rotating annular knife (15) and the knife frame (14). At this time, the roadbed sand and gravel can perform centrifugal motion under the rotation of the annular knife (15) and the knife frame (14) and fall on the highway roadbed.
