Description

Technical Field

[0001] The invention relates to a soil foundation compaction technology, in particular to a cyclic progressive roadbed slope compactor and a compaction method thereof. Background Art

[0002] In highway and railway construction, the stability of the roadbed is a key factor in ensuring the quality of the project and driving safety. Due to the different environments of the construction sites, the roadbed conditions are also different, mainly including soft soil area roadbed, landslide area roadbed, rock collapse and rock pile area roadbed, debris flow area roadbed, karst area foundation, permafrost area roadbed, loess area roadbed, expansive soil area roadbed, expansive soil area roadbed, desert area roadbed, snow damage area roadbed and snow damage area roadbed, among which soft soil roadbed is the most common type of roadbed in our construction.

[0003] For soft soil roadbed treatment, methods such as compaction and drainage consolidation are generally adopted to improve the characteristics of soft soil foundation and extend the service life and comfort of the road. During the compaction and drainage consolidation process, the force on the soil foundation will overflow to the slope.

[0004] Generally, the road construction process will be coordinated with measures such as covering the slopes with vegetation to reinforce them, or adding retaining walls. However, during the construction process, if there is rain or snow, especially severe conditions such as heavy rainfall and erosion, it is very easy for the unfinished soil foundation slopes to sink, collapse, and collapse.

[0005] In order to ensure the density of the slope and avoid unexpected situations during the construction process, the slope reinforcement and compaction will also be carried out during the soil foundation laying and compaction. The compaction of the slope is different from the compaction of the roadbed. Since the roadbed has a slope, conventional compactors cannot operate on steep slopes, so they are mostly operated with the help of engineering machinery (such as excavators).

[0006] A common way to compact slopes is to use an excavator bucket to pat and compact them. However, due to the soft nature of the soil base, there is a slight rebound after one compaction, so the excavator bucket needs to pat several times to completely compact it. As the number of patting and compaction increases, the amount of subsidence of the slope soil base continues to increase, so the patting depth needs to be adjusted continuously. However, the change in the amount of subsidence is small, so the depth increase for each pat is small. If the controlled patting depth increase is too small, the compaction will not be obvious based on the previous compaction. If the increase is too large, the machine load will be too large, causing greater damage to the equipment (including deformation and breakage of the mechanical arm, and leakage of the oil cylinder). The operation process is not only cumbersome, but also tests the experience of the operators. Summary of the invention

[0017] A method for cyclic progressive compaction of a roadbed slope using the compactor as described above comprises the following steps: Step 1: Machine inspection: Check whether the frame is at the highest point of its travel and ensure that the front edge of the movable frame is above the ground level; Step 2: Level the pallet operation station, drive the engineering vehicle so that its front end corresponds to the loose roadbed slope soil, then control the height adjustment cylinder to extend and retract to drive the swing arm to swing, and then adjust the height of the rotating shaft to adjust the height of the rear ridge and the entire pallet; Then the angle adjustment cylinder is controlled to extend and retract to drive the rear ridge to rotate around the axis to adjust the angle of the support plate. The two are combined to make the support plate close to the roadbed slope and parallel to the roadbed slope. When the height and angle of the pallet are adjusted by the height adjustment cylinder and the angle adjustment cylinder respectively, so that the pallet and the slope are basically in contact and parallel, the telescopic cylinder is used to extend and retract to drive the movable frame to move downward along the length direction of the pallet, so that the movable frame moves downward until the compaction plate faces the working plane of the slope; Step 3: Start compaction, control the drive cylinder to work and drive the main shaft to vibrate up and down through the connecting rod, and the main shaft drives the vibration plate and the compaction plate to vibrate back and forth. When the compaction plate runs to the end of the stroke, check whether the compaction strength of the roadbed slope is qualified; If the strength is insufficient, the compaction plate is restored to its initial position by the return motor, and the height adjustment cylinder and the angle adjustment cylinder are readjusted so that the compaction plate restored to its initial position is close to the slope after the first compaction; then the drive cylinder is restarted for the second compaction; Step 4: Change position. After compaction at the current position, start the return cylinder and use the return motor to return the compaction plate to the initial position. Control the movable frame to shrink to a height above the ground level through the telescopic cylinder, and drive the engineering vehicle to change position to the next workstation.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: the present invention effectively prevents soil base rebound through multiple cycles of vibration compaction; and during each vibration, the vibration depth of the compaction plate increases continuously, so that the soil base of the slope can be compacted step by step, and finally fully compacted, and the difference in compaction depth between two adjacent times is small, which greatly reduces the single operation load of the driving cylinder; With the help of the double-effect locking assembly, the main shaft can vibrate synchronously with the compaction plate when driving the vibration plate to vibrate downward; and increase the distance between the compaction plate and the vibration plate during the upward reset process; Since the telescopic end of the driving cylinder has a constant telescopic amount each time, the vibration depth of the vibration plate is constant each time. By increasing the distance between the compaction plate and the vibration plate during each rising and resetting process, the vibration depth of the compaction plate that ultimately performs the compaction operation is continuously increased each time.

[0050] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0051] See also Figure 1 to Figure 30 As an embodiment of the present invention, the cyclic progressive roadbed slope compactor is attached to an engineering vehicle 1, and the height, angle, orientation, etc. of the compactor are adjusted by the engineering vehicle 1.

[0052] Specifically, the cyclic progressive roadbed slope compactor comprises a support plate 2 and a movable frame 3 which is adjustably and movably arranged on the support plate 2 along the length direction of the support plate 2; See also Figure 3 and Figure 4 A plurality of brackets 301 are symmetrically fixedly installed on the two side edges of the movable frame 3, and a bracket slot 202 is opened on both sides of the support plate 2 along its length direction, and the bracket slot 202 passes through the support plate 2, and the bracket 301 passes through the bracket slot 202; A lower roller 302 is rotatably mounted on the lower end of the bracket 301 , and an upper roller 303 is rotatably mounted on the lower portion of the movable frame 3 . The upper roller 303 rolls against the upper portion of the support plate 2 , and the lower roller 302 rolls against the lower portion of the support plate 2 .

[0053] The movable frame 3 is supported on the pallet 2 by using a plurality of upper rollers 303, and at the same time, the lower rollers 302 are used to prevent the movable frame 3 from detaching from the pallet 2; precisely because of the roller design, the friction between the two is smaller during the process of adjusting the movable frame 3 on the pallet 2 along the length direction of the pallet 2.

[0054] See also Figure 1~Figure 4 The front end of the engineering vehicle 1 is provided with a swing arm 101, the rear end of the swing arm 101 is rotatably connected to the engineering vehicle 1, and a height adjustment cylinder 103 is further provided between the swing arm 101 and the engineering vehicle 1, the rear end of the height adjustment cylinder 103 is rotatably connected to the engineering vehicle 1, and the front end of the height adjustment cylinder 103 is rotatably connected to the swing arm 101; The swing arm 101 is also rotatably provided with a rotating shaft 102 , and a rear spine 201 is integrally formed on the back of the support plate 2 , and the rotating shaft 102 and the rear spine 201 are rotatably connected.

[0055] By controlling the extension and retraction of the height-adjusting cylinder 103 , the swing arm 101 can be driven to swing, thereby adjusting the height of the rotating shaft 102 , and finally adjusting the height of the rear spine 201 and the entire support plate 2 .

[0056] The rear spine 201 is also connected to the front end of the engineering vehicle 1 through an angle adjustment cylinder 104 , one end of the angle adjustment cylinder 104 is rotatably connected to the front end of the engineering vehicle 1 , and the other end of the angle adjustment cylinder 104 is rotatably connected to the rear spine 201 .

[0057] Controlling the extension and retraction of the angle adjustment cylinder 104 can drive the rear spine 201 to rotate around the rotation axis 102 , thereby adjusting the angle of the support plate 2 .

[0058] A connecting shaft 401 is rotatably mounted on the front end of the swing arm 101, and the connecting shaft 401 is connected to the movable frame 3 via a telescopic cylinder 4; Among them, one end of the telescopic cylinder 4 is rotatably connected to the connecting shaft 401 , and the other end of the telescopic cylinder 4 is rotatably connected to the side of the movable frame 3 .

[0059] It should be noted that the telescopic cylinder 4 , the height adjustment cylinder 103 , and the angle adjustment cylinder 104 include but are not limited to hydraulic cylinders and air cylinders, and are preferably hydraulic cylinders.

[0060] After the height and angle of the support plate 2 are adjusted by the height adjustment cylinder 103 and the angle adjustment cylinder 104 respectively, the telescopic cylinder 4 can be used to move the movable frame 3 upward or downward along the length direction of the support plate 2, so that the movable frame 3 can move upward or downward.

[0061] During the slope foundation compaction operation, the movable frame 3 is kept protruding downward from the support plate 2; after the operation is completed, the movable frame 3 can be controlled to retract upward to overlap with the support plate 2 to ensure that the bottom of the movable frame 3 is higher than the ground and does not affect the driving of the engineering vehicle 1.

[0062] As a further solution of the present invention, please refer to Figure 5 , Figure 7 , Figure 8 ,as well as Fig. 9 The cyclic progressive roadbed slope compactor further includes a vibration plate 5 parallel to the support plate 2 and the movable frame 3, and a compaction plate 6 parallel to the vibration plate 5; Slide rods 501 perpendicular to the vibration plate 5 are arranged around the vibration plate 5, and side frames 304 are arranged on the sides of the movable frame 3. Slide sleeves 305 are fixedly installed on the side frames 304, and the slide rods 501 penetrate the slide sleeves 305 and slide with the slide sleeves 305. A driving cylinder 7 is installed on the movable frame 3 along its length direction, and the driving cylinder 7 is connected to the vibration plate 5 through a compaction assembly, and a plurality of groups of fine-tuning mechanisms are arranged between the vibration plate 5 and the compaction plate 6; The driving cylinder 7 can drive the vibration plate 5 to reciprocate and vibrate along the axis direction of the slide bar 501 under the action of the compacting assembly. When the vibration plate 5 reciprocates and vibrates along the axis direction of the slide bar 501, it drives the compacting plate 6 to reciprocate and vibrate synchronously. And under the action of the fine-tuning mechanism, the vibration depth of the compacting plate 6 gradually increases.

[0063] The roadbed cushion soil has a large inclination angle at the slope position, so it is generally necessary to compact it during the construction process to prevent soil loss caused by rainy weather. Since the slope soil base is relatively soft, the depth of settlement during the compaction process is large, and it cannot be completely compacted in one operation.

[0064] In the present invention, multiple cycles of vibration compaction are performed to effectively prevent soil base rebound; and during each vibration, the vibration depth of the compaction plate 6 increases continuously, so that the soil base of the slope can be compacted step by step, and finally fully compacted, and the difference in compaction depth between two adjacent times is small, which greatly reduces the single operation load of the drive cylinder 7.

[0065] As a further solution of the present invention, please refer to Figure 5 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 ,as well as Fig.11 The compacting assembly includes a main shaft 9 having one end fixedly connected to the vibration plate 5, and a connecting rod 8 connecting the main shaft 9 and the drive cylinder 7; One end of the connecting rod 8 is rotatably connected to the telescopic end of the driving cylinder 7, and the other end of the connecting rod 8 is rotatably connected to the other end of the main shaft 9; A cross frame 11 is fixedly mounted on the movable frame 3 , a through hole is provided in the center of the cross frame 11 for the main shaft 9 to movably pass through, a rotating sleeve 10 is rotatably mounted at the through hole, and the main shaft 9 and the rotating sleeve 10 are fitted together.

[0066] The telescopic end of the driving cylinder 7 cooperates with the connecting rod 8 to achieve the process of reciprocating extension and retraction of the telescopic end of the driving cylinder 7, and drives the main shaft 9 to continuously reciprocate and vibrate along the axis direction of the slide bar 501. Since one end of the main shaft 9 is fixedly connected to the vibration plate 5, the vibration plate 5 can be driven to follow the vibration during the vibration of the main shaft 9; the movement of the vibration plate 5 and the main shaft 9 is guided by the cooperation of the set sliding sleeve 305 and the slide bar 501. In addition, the upper part of the main shaft 9 is constrained by the sleeve of the main shaft 9 and the rotating sleeve 10 to prevent the main shaft 9 from bending and deformation.

[0067] As a further solution of the present invention, please refer to Fig.23 , Fig.25 ,as well as Fig.26, the fine-tuning mechanism includes an adjusting column 25 parallel to the main shaft 9 and rotatably connected to the vibration plate 5, and an internal threaded sleeve 26 fixed on the compacting plate 6; The lower part of the adjusting column 25 forms an external thread section, the external thread section and the internal thread sleeve 26 are threadedly matched, and a bearing for rotationally connecting with the adjusting column 25 is provided at the lower part of the vibration plate 5; The adjusting column 25 is connected to the main shaft 9 through a double-effect locking assembly. When the main shaft 9 vibrates downward, the double-effect locking assembly keeps the adjusting column 25 stationary relative to the internal threaded sleeve 26, so as to drive the compacting plate 6 and the vibration plate 5 to vibrate downward synchronously; When the main shaft 9 is reset upward, the adjusting column 25 is driven to rotate relative to the internal threaded sleeve 26, so as to drive the compacting plate 6 to move away from the vibration plate 5 during the process of being reset upward together with the vibration plate 5.

[0068] In the present invention, by means of the double-effect locking assembly, the main shaft 9 is made to vibrate synchronously with the compaction plate 6 in the process of driving the vibration plate 5 to vibrate downward; and in the process of ascending and resetting, the distance between the compaction plate 6 and the vibration plate 5 is increased; Since the telescopic end of the driving cylinder 7 has a constant telescopic amount each time, the vibration depth of the vibration plate 5 is constant each time. By increasing the distance between the compaction plate 6 and the vibration plate 5 during each rising and resetting process, the vibration depth of the compaction plate 6 that finally performs the compaction operation is continuously increased each time.

[0069] It should be noted that the reason for increasing the distance between the compaction plate 6 and the vibration plate 5 during the ascending and resetting process is because the ascending and resetting process is a no-load operation; if the distance between the two is increased during the downward vibration, the load of the drive cylinder 7 will inevitably be increased on the basis of the vibration; through such a setting, the kinetic energy of the extension and contraction strokes of the drive cylinder 7 can be cleverly fully utilized, so that the load of the drive cylinder 7 is dispersed and the work is balanced.

[0070] Theoretically, the same effect can be achieved by controlling the single extension amount of the telescopic end of the drive cylinder 7 so that the extension length increases each time. However, in actual operation, the driver of the engineering vehicle 1 cannot manually and accurately control the extension amount, because the single extension amount is a small control and is not easy to control. Even if the ability of precise control can be achieved, the extension amount of the drive cylinder 7 will inevitably increase continuously, so that in the subsequent compaction operation, the piston rod of the drive cylinder 7 extends for a long length. Under the influence of the compaction reaction force, there is a high risk of deformation, bending, leakage, etc.; in the present invention, the telescopic end of the drive cylinder 7 always operates at a smaller extension length, the extension amount is always constant, and the length is short, resulting in a shorter force arm of the compaction reaction force. Therefore, the risk of bending, deformation, leakage, etc. of the piston rod of the drive cylinder 7 is greatly reduced.

[0071] As a further solution of the present invention, please refer to Fig.11 , Fig.12 ,as well as Fig.13 , two sections of spiral raceways 1001 are arranged on the inner wall of the rotating sleeve 10, the two sections of the spiral raceways 1001 are spaced 180° apart, and have the same spiral rotation direction; Two balls 901 are rollingly engaged on the outer wall of the main shaft 9, and the two balls 901 are rollingly engaged with the two sections of the spiral raceway 1001 respectively; See also Figure 14~Figure 17 The double-effect locking assembly includes a primary locking structure connecting the rotating sleeve 10 and the driving gear 12, and the driving gear 12 is rotatably arranged outside the rotating sleeve 10; the driving gear 12 is a two-half structure and is detachably connected through a connecting block 1201; the primary locking structure includes a toothed ring 13 arranged on the outer wall of the rotating sleeve 10, and a circle of fixed arc-shaped teeth 1301 is formed on the outer wall of the toothed ring 13; A circle of radial grooves 1203 is formed on the inner wall of the driving gear 12, and the radial grooves 1203 and one end of the telescopic arc-shaped teeth 14 are slidably matched, and the telescopic arc-shaped teeth 14 are elastically matched with the radial grooves 1203 through the retaining spring 15; Specifically, the retaining spring 15 is placed in the radial groove 1203, and one end of the retaining spring 15 abuts against the bottom of the radial groove 1203, and the other end of the retaining spring 15 abuts against one end of the telescopic arc-shaped tooth 14 sliding in the radial groove 1203; The retaining spring 15 is kept in a compressed state, the fixed arc-shaped teeth 1301 are distributed along the radial direction of the gear ring 13, and the telescopic arc-shaped teeth 14 are distributed along the radial direction of the driving gear 12; One side of the fixed arc-shaped tooth 1301 is an arc-shaped portion, and the other side is a straight portion; one side of the telescopic arc-shaped tooth 14 is also an arc-shaped portion, and the other side is a straight portion; Two circles of rollers 1202 are rollingly engaged on the inner ring of the driving gear 12 , and two circles of grooves 1002 are formed on the outer wall of the rotating sleeve 10 . The two circles of rollers 1202 are rollingly engaged with the two circles of grooves 1002 .

[0072] In the present invention, the driving gear 12 is configured as a two-half structure, which facilitates the roller 1202 to be inserted into the recess 1002 and realizes the rotation connection between the driving gear 12 and the rotating sleeve 10.

[0073] For the sake of convenience, we now combine Fig.12 and Fig.13To explain, when the connecting rod 8 drives the main shaft 9 to vibrate downward, since the lower end of the main shaft 9 is fixed to the vibration plate 5, and the vibration plate 5 can only move up and down under the guidance of the slide bar 501 and the sleeve 305, the main shaft 9 can only vibrate up and down along the axis of the slide bar 501; that is, the balls 901 on both sides can only move up and down along the axis of the slide bar 501, and the balls 901 are rollingly engaged in the spiral raceway 1001, and the rotating sleeve 10 is rotatably set on the cross frame 11. Therefore, in the process of the up and down movement of the balls 901, the rotating sleeve 10 cannot follow the up and down movement, resulting in the rotating sleeve 10 can only rotate.

[0074] from Fig.12 and Fig.13 From the middle, when the main shaft 9 and the balls 901 on both sides move downward, the rotating sleeve 10 rotates counterclockwise, and when it rises, the rotating sleeve 10 rotates clockwise; when the rotating sleeve 10 rotates counterclockwise, it drives the gear ring 13 to rotate counterclockwise.

[0075] According to Fig.14 and Fig.16 as well as Fig.17 It can be seen that when the gear ring 13 rotates counterclockwise, if the driving gear 12 has a large rotation resistance, the arc-shaped portion of the fixed arc-shaped tooth 1301 squeezes the arc-shaped portion of the telescopic arc-shaped tooth 14, causing the telescopic arc-shaped tooth 14 to shrink into the radial groove 1203 and further compress the retaining spring 15, thereby ensuring that the driving gear 12 does not rotate by the telescopic arc-shaped tooth 14 giving way; if the gear ring 13 rotates clockwise, the straight portion of the fixed arc-shaped tooth 1301 squeezes the straight portion of the telescopic arc-shaped tooth 14, and no radial component force can be generated, resulting in the telescopic arc-shaped tooth 14 not giving way. Therefore, the telescopic arc-shaped tooth 14 can only rotate clockwise with the gear ring 13.

[0076] As a further solution of the present invention, please refer to Fig.18 , Fig.19 ,as well as Fig. 20 The double-effect locking assembly further includes a plurality of adjustable sleeves 16 arranged around the main shaft 9, the lower end of the adjustable sleeve 16 is rotatably mounted on the vibration plate 5, the upper end of the adjustable sleeve 16 is rotatably connected to a longitudinal frame 17, the longitudinal frame 17 is fixed on the vibration plate 5, and the adjustable sleeve 16 is provided with a driven gear 18 meshing with the driving gear 12; See also Fig.23 and Fig.26It should be noted that an axial hole is opened on the vibration plate 5, and the adjusting column 25 penetrates the axial hole. A group of bearings are arranged at the lower part of the axial hole, and the bearings are used to rotatably connect the adjusting column 25 and the lower part of the vibration plate 5; the lower end of the pitch adjusting sleeve 16 is arranged above the axial hole, and is rotatably connected to the upper part of the vibration plate 5 through another group of bearings, and a group of bearings connecting the upper part of the vibration plate 5 and the pitch adjusting sleeve 16 are arranged at the upper part of the axial hole, and the upper end of the pitch adjusting sleeve 16 and the lower surface of the longitudinal frame 17 are rotatably matched.

[0077] An upper triangular gear ring 23 is arranged outside the pitch-adjusting sleeve 16, and a lower triangular gear ring 22 is arranged below the upper triangular gear ring 23. A plurality of groups of columns 19 are arranged on the vibrating plate 5, and each group of columns 19 has at least two columns. A circle of steps is formed on the columns 19, and a stopper sheet 20 is slidably sleeved on the same group of columns 19, and the lower part of the stopper sheet 20 is in contact with the step; a through hole is opened in the center of the stopper sheet 20 to match the clearance of the pitch-adjusting sleeve 16, and a lifting spring 21 is arranged between the stopper sheet 20 and the lower triangular gear ring 22; The lower end of the lifting spring 21 abuts against the stopper plate 20 , and the upper end abuts against the lower triangular gear ring 22 , and the lifting spring 21 has compressive elastic potential energy.

[0078] Obviously, the lower edge of the upper triangular gear ring 23 forms a circle of right-angled triangular teeth, and the upper edge of the lower triangular gear ring 22 also forms a circle of right-angled triangular teeth, one side of the right-angled triangular teeth is an inclined surface, and the other side is a vertical surface.

[0079] Combination Fig.18 , Fig.19 ,as well as Fig. 20 As shown, under the action of the compressive elastic potential energy of the lifting spring 21, the lower triangular gear ring 22 is always subjected to an upward elastic force, so the lower triangular gear ring 22 can be kept in a state of always being engaged with the upper triangular gear ring 23.

[0080] Since the column 19 is fixed on the vibration plate 5, and the lower triangular gear ring 22 is slidably fitted with the column 19, the lower triangular gear ring 22 cannot rotate; and it can be seen from the figure that when the upper triangular gear ring 23 rotates counterclockwise, the lower triangular gear ring 22 cannot rotate with it, and can only make way by sliding downward to further compress the lifting spring 21; and when the upper triangular gear ring 23 rotates clockwise, due to the interaction between the vertical surfaces of the right-angled triangular teeth on the upper triangular gear ring 23 and the vertical surfaces of the right-angled triangular teeth on the lower triangular gear ring 22, it is impossible to generate a downward component force on the lower triangular gear ring 22, resulting in the lower triangular gear ring 22 being unable to make way, thereby locking the upper triangular gear ring 23, that is, the upper triangular gear ring 23 can only rotate counterclockwise, but not clockwise.

[0081] When the gear ring 13 rotates counterclockwise, the driving gear 12 has a tendency to rotate counterclockwise following the gear ring 13, because the upper triangular gear ring 23 can only rotate counterclockwise, resulting in the pitch-adjusting sleeve 16 fixed to the upper triangular gear ring 23 can only rotate counterclockwise, and then the driven gear 18 fixed to the pitch-adjusting sleeve 16 can only rotate counterclockwise, and finally the driving gear 12 meshing with the driven gear 18 can only rotate clockwise, that is, the driving gear 12 cannot rotate counterclockwise; Because the driving gear 12 cannot rotate the rod counterclockwise, when the gear ring 13 rotates counterclockwise, the arc portion of the fixed arc tooth 1301 squeezes the arc portion of the telescopic arc tooth 14, causing the telescopic arc tooth 14 to shrink into the radial groove 1203 and further compress the retaining spring 15. The telescopic arc tooth 14 gives way to ensure that the driving gear 12 will not rotate counterclockwise with the gear ring 13. Correspondingly, when the gear ring 13 rotates clockwise, the straight portion of the fixed arc-shaped tooth 1301 squeezes the straight portion of the telescopic arc-shaped tooth 14. Since the telescopic arc-shaped tooth 14 will not give way, the telescopic arc-shaped tooth 14 will rotate clockwise with the gear ring 13, and finally make the driving gear 12 rotate clockwise. When the driving gear 12 rotates clockwise, it will drive the driven gear 18 to rotate counterclockwise. When the driven gear 18 rotates counterclockwise, it will drive the upper triangular gear ring 23 to rotate counterclockwise.

[0082] To sum up, through the arrangement of the above-mentioned structure, in the process that the main shaft 9 drives the vibration plate 5 and the compaction plate 6 to impact and vibrate downward, the main shaft 9 uses the balls 901 on both sides to drive the rotating sleeve 10 to rotate counterclockwise, and the counterclockwise rotation of the rotating sleeve 10 cannot drive the driving gear 12 to rotate; however, in the process that the main shaft 9 drives the vibration plate 5 and the compaction plate 6 to reset upward, the balls 901 on both sides of the main shaft 9 drive the rotating sleeve 10 to rotate clockwise, and the clockwise rotating rotating sleeve 10 can drive the driving gear 12 to rotate clockwise, and the clockwise rotating driving gear 12 can drive multiple driven gears 18 to rotate counterclockwise; that is, when the main shaft 9 vibrates and impacts downward, the distance adjusting sleeve 16 does not rotate, and when the main shaft 9 resets upward, the distance adjusting sleeve 16 rotates counterclockwise.

[0083] As a further solution of the present invention, please refer to Figure 21~Figure 30 , the double-effect locking assembly also includes a secondary locking structure connecting the distance adjusting sleeve 16 and the adjusting column 25; The secondary locking structure includes a clutch sleeve 24 disposed in the distance adjustment sleeve 16 and sleeved on the outside of the adjustment column 25; The outer wall of the clutch sleeve 24 is provided with a plurality of external teeth 2401, and the outer wall of the adjustable sleeve 16 is provided with a plurality of sliding grooves 1601, and the external teeth 2401 and the sliding grooves 1601 are slidably matched; The inner wall of the clutch sleeve 24 is provided with a plurality of inner teeth 2402, and the upper outer wall of the adjustment column 25 is provided with a plurality of racks 2501 at equal intervals along the circumference, and a tooth groove is formed between two adjacent racks 2501; An inner flange 1602 is provided on the inner wall of the distance adjustment sleeve 16, and a compression spring 29 is provided on the outer sleeve of the adjustment column 25. The lower end of the compression spring 29 abuts against the inner flange 1602, and the upper end of the compression spring 29 abuts against the bottom of the clutch sleeve 24, so that the compression spring 29 remains in a compressed state.

[0084] When the clutch sleeve 24 is not subjected to external force, the compression spring 29 gives the clutch sleeve 24 an upward elastic force, so that the outer teeth 2401 fit with the top of the slide groove 1601, and the inner teeth 2402 are embedded in the tooth groove; When the distance-adjusting sleeve 16 rotates counterclockwise, the outer teeth 2401 are driven to rotate by the slide groove 1601, and the outer teeth 2401 drive the clutch sleeve 24 to rotate. The clutch sleeve 24 then cooperates with the tooth grooves formed by the inner teeth 2402 and the two adjacent racks 2501, and finally drives the adjusting column 25 to rotate counterclockwise; when the adjusting column 25 rotates counterclockwise, the external thread section formed at the lower part thereof will also rotate counterclockwise. Since the internal thread sleeve 26 cannot rotate, the internal thread sleeve 26 can only gradually move away from the vibration plate 5 during the counterclockwise rotation of the external thread section, thereby finally achieving the function of increasing the distance between the compacting plate 6 and the vibration plate 5.

[0085] As a further solution of the present invention, please refer to Figure 21~Figure 30 , the vibration plate 5 is also provided with a return mechanism, and the return mechanism is used to reduce the distance between the compaction plate 6 and the vibration plate 5 so that the compaction plate 6 returns to its initial position; The return mechanism comprises a return sleeve 27, one end of which is sleeved in the adjustable sleeve 16 and is located between the rack 2501 and the inner wall of the adjustable sleeve 16; the other end of the return sleeve 27 extends from the upper end of the adjustable sleeve 16, and an upper tooth block 2702 is provided on a section of the outer wall of the adjustable sleeve 16 where the return sleeve 27 extends; A circle of lower gear blocks 2701 is arranged on the lower inner wall of the return sleeve 27, and the return sleeve 27 is adjustably sleeved on the outside of the distance adjustment sleeve 16 through a lifting structure; The upper and lower ends of the rack 2501 both form sharp portions, and the lower end of the lower tooth block 2701 and the upper end of the inner tooth 2402 also form sharp portions.

[0086] When the distance between the compacting plate 6 and the vibration plate 5 needs to be reduced to the initial state, the return sleeve 27 is driven downward by the lifting structure, wherein, after the lower end of the return sleeve 27 contacts the upper end of the clutch sleeve 24, as the return sleeve 27 continues to move downward, the clutch sleeve 24 is driven to move downward to further compress the compression spring 29; During the downward movement of the clutch sleeve 24, the outer teeth 2401 slide along the slide groove 1601 and approach the vibration plate 5, until the inner teeth 2402 are completely disengaged from the lower part of the tooth groove, and the lower tooth block 2701 begins to be embedded from the upper part of the tooth groove; once the lower tooth block 2701 is completely embedded in the tooth groove, it is only necessary to rotate the return sleeve 27 clockwise to drive the adjusting column 25 to rotate clockwise, and when the adjusting column 25 rotates clockwise, the distance between the compacting plate 6 and the vibration plate 5 can be reduced through the cooperation of the outer thread section and the inner thread sleeve 26 at the lower part, until the compacting plate 6 returns to its initial position.

[0087] As a further solution of the present invention, please refer to Figure 5 , Figure 6 , Fig.26 , Fig.29 ,as well as Fig.30 The lifting structure includes a sleeve 35, a leakage hole is provided in the center of the sleeve 35 for the main shaft 9 to pass through, and the upper end of the return sleeve 27 is rotatably matched with the sleeve 35; the sleeve 35 is connected to the vibration plate 5 through a return cylinder 36, one end of the return cylinder 36 is rotatably connected to the vibration plate 5, and the telescopic end of the return cylinder 36 is rotatably connected to the sleeve 35; A return drive sleeve 28 is rotatably mounted on the upper part of the longitudinal frame 17, an embedding groove 2801 is provided on the inner wall of the return drive sleeve 28, the upper tooth block 2702 and the embedding groove 2801 are slidably matched, and a sprocket 33 is fixedly mounted on the outer wall of the return drive sleeve 28, and two adjacent sprockets 33 are connected by a chain 34; A return motor 30 is installed on the longitudinal frame 17 , and a small bevel gear 31 is installed on the output shaft of the return motor 30 . A large bevel gear 32 meshing with the small bevel gear 31 is fixedly installed on one of the return drive sleeves 28 .

[0088] In the present invention, when the distance between the compaction plate 6 and the vibration plate 5 needs to be reduced, the return cylinder 36 only needs to be controlled to contract to drive the sleeve 35 to move downward, and the downward movement of the sleeve 35 drives the return sleeve 27 rotatably connected thereto to move downward; The lower end of the return sleeve 27 will push against the clutch sleeve 24 to further compress the compression spring 29 so that the inner tooth 2402 will be disengaged from the tooth groove, and then the lower tooth block 2701 will be embedded in the tooth groove, so that the adjustment column 25 is disconnected from the distance adjustment sleeve 16, and the adjustment column 25 and the return sleeve 27 are connected; When the return sleeve 27 moves downward, the upper tooth block 2702 slides downward along the embedded groove 2801 to keep the return sleeve 27 connected to the return drive sleeve 28. The return motor 30 drives the return drive sleeves 28 to rotate clockwise, which can drive the multiple adjustment columns 25 to rotate clockwise, so that the compacting plate 6 can achieve fast and convenient return.

[0089] The two ends of the rack 2501 are set to be sharp, and the sharp parts formed by the lower end of the lower tooth block 2701 and the upper end of the inner tooth 2402 are mainly used to guide the lower tooth block 2701 to be embedded in the tooth groove and the inner tooth 2402 to be embedded in the tooth groove to avoid jamming.

[0090] In the present invention, the connection between the distance adjusting sleeve 16 and the adjusting column 25, and the connection between the adjusting column 25 and the return sleeve 27 are switched by means of a specially designed clutch sleeve 24 and tooth grooves; when the distance adjusting sleeve 16 drives the adjusting column 25 to rotate counterclockwise, the return sleeve 27 is not disturbed and does not need to rotate with it; similarly, when the return sleeve 27 drives the adjusting column 25 to rotate clockwise, the distance adjusting sleeve 16 is also not disturbed.

[0091] In addition, the present invention also provides a method for cyclically and progressively compacting a roadbed slope using the compactor as described above, comprising the following steps: Step 1: Machine inspection: Check whether the sleeve frame 35 is at the highest point of its travel and ensure that the front edge of the movable frame 3 is above the ground level; Step 2: The pallet 2 is leveled at the workstation, the engineering vehicle 1 is driven to make its front end correspond to the loose roadbed slope soil, and then the height adjustment cylinder 103 is controlled to extend and retract to drive the swing arm 101 to swing, and then the height of the rotating shaft 102 is adjusted to adjust the height of the rear ridge 201 and the entire pallet 2; Then the angle adjustment cylinder 104 is controlled to extend and retract to drive the rear spine 201 to rotate around the rotating shaft 102 to adjust the angle of the support plate 2. The two are combined to adjust the support plate 2 so that the support plate 2 is close to the roadbed slope and parallel to the roadbed slope. When the height and angle of the support plate 2 are adjusted by the height adjustment cylinder 103 and the angle adjustment cylinder 104 respectively, so that the support plate 2 and the slope are basically in contact and parallel, the telescopic cylinder 4 is used to telescope and drive the movable frame 3 to move downward along the length direction of the support plate 2, so that the movable frame 3 moves downward until the compaction plate 6 faces the working plane of the slope; Step 3: Start compaction, control the drive cylinder 7 to work and drive the main shaft 9 to vibrate up and down through the connecting rod 8, and the main shaft 9 drives the vibration plate 5 and the compaction plate 6 to vibrate back and forth. When the compaction plate 6 runs to the end of the stroke, check whether the compaction strength of the roadbed slope is qualified; If the strength is insufficient, the compaction plate 6 is restored to the initial position by the return motor 30, and the height adjustment cylinder 103 and the angle adjustment cylinder 104 are readjusted so that the compaction plate 6 restored to the initial position is close to the slope after the primary compaction; and the drive cylinder 7 is restarted to perform secondary compaction; Step 4, change position. After the current position is compacted, start the return cylinder 36, and use the return motor 30 to return the compaction plate 6 to the initial position. Control the movable frame 3 to shrink to a height above the ground level through the telescopic cylinder 4, and drive the engineering vehicle 1 to change position to the next workstation.

[0092] The above embodiments are exemplary rather than restrictive, so the technical solutions of the present invention that can be implemented in other specific forms without departing from the spirit or basic features of the present invention are all included in the present invention.
