Description

Technical Field

[0001] This invention pertains to road construction equipment, specifically, to a vehicle-mounted compaction device for roadbed slopes. Background Technology

[0002] Roadbed slope compaction is a crucial step in road construction. It refers to the process of compacting the soil on roadbed slopes using specific techniques and methods to improve their density and stability. To ensure the stability and safety of the roadbed, the slope gradient may vary depending on the terrain and soil characteristics.

[0003] Currently, compaction devices are commonly used to compact slopes to improve the density and stability of roadbed slopes, thereby ensuring the overall quality and safety of road engineering projects. For example, Chinese Patent No. CN2320661Y discloses a roadbed slope compactor based on an engineering vehicle. Its key feature is that it uses a tracked bulldozer as the base vehicle and a simple cylindrical vibrating roller with an internal hydraulic drive motor as the compaction device. The compaction device is side-suspended on the bulldozer by a parallel four-bar linkage mechanism and is adjusted and positioned by three hydraulic cylinders connected to the bulldozer's hydraulic system.

[0004] In actual construction, when the above-mentioned device is used to roll the slope, its longitudinal vibrating roller is driven by a parallel four-bar linkage mechanism. Since the slope is relatively wide, and the lateral movement distance of the vibrating roller driven by the parallel four-bar linkage mechanism is limited, when rolling on a wide slope, the bulldozer needs to move back and forth multiple times to roll the slope, which is inefficient. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides a vehicle-mounted compaction device for roadbed slopes, the specific technical solution of which is as follows: A vehicle-mounted compaction device for roadbed slopes includes a frame articulated on a vehicle, the frame and the vehicle being connected by a hydraulic cylinder. A power unit is mounted on the frame, and a reciprocating sliding component is also mounted on the frame. The power unit drives the reciprocating sliding component to move back and forth, and the reciprocating sliding component moves back and forth along a direction perpendicular to the driving direction. A reciprocating pressing component is mounted on the reciprocating sliding component, and the reciprocating pressing component is used to compact the slope.

[0006] The vehicle moves along the roadbed, which in turn moves the frame. The reciprocating pressing component compacts the slope, and the power component drives the reciprocating sliding component to move, thereby increasing the width of the compacted slope. This avoids the need for the vehicle to move back and forth to compact the slope, thus improving construction efficiency.

[0007] In one specific implementation, the frame is provided with a guide rail, the guide rail is arranged perpendicular to the travel direction, the reciprocating sliding assembly includes a moving plate, the power assembly drives the moving plate to move within the guide rail, the moving plate is provided with a pushing groove, and the bottom wall of the pushing groove is provided with a moving groove. The reciprocating sliding assembly further includes a moving rod, on which a sliding column and a moving block are respectively provided. The sliding column slides in the pushing inclined groove, and the moving block slides in the moving slot. A limiting block is provided at one end of the moving rod that passes through the moving slot. The pushing inclined groove constrains the sliding column, so that the moving block slides along the first sliding groove, the transverse groove, and the second sliding groove respectively. The sliding column is connected to the reciprocating pressing assembly, and the width of the moving block is equal to the width of the moving slot.

[0008] The pushing chute and the moving chute are the core coordinating components for realizing the compound motion of the reciprocating pressing component. The pushing chute generates a pushing / pulling force on the sliding column through the chute wall, driving the sliding column to complete the vertical lifting and lowering with the horizontal movement of the moving plate. The moving chute limits the movement trajectory of the moving block, so that the moving block can only move along the path of "vertical upward movement - horizontal lateral movement - vertical downward movement". The two work together to transform the single horizontal movement of the moving plate into the "horizontal + vertical" compound motion of the reciprocating pressing component, achieving the technical effect of expanding the single compaction width without the need for the vehicle to travel back and forth.

[0009] In one specific implementation, the pushing chute is composed of a first chute and a second chute, which are interconnected and form a V-shaped groove. The moving chute includes a first sliding groove, a transverse groove, and a second sliding groove. The intersection of the first and second chutes includes a highest point and a lowest point. The height of the lowest point is the same as the height of the bottom wall of the transverse groove. The first sliding groove, the transverse groove, and the second sliding groove are interconnected and form a C-shaped groove. The opening direction of the C-shaped groove is the same as the opening direction of the V-shaped groove. When the sliding column moves in the first chute, the inclined groove wall of the first chute pushes the sliding column upward, causing the moving block to move upward along the first sliding groove. The transverse groove allows the sliding column to move perpendicular to the travel direction. When the sliding column moves in the second chute, the inclined groove wall of the second chute guides the sliding column downward, causing the moving block to move downward along the second sliding groove.

[0010] The power unit pushes the moving plate along the sliding chute to move away from the vehicle, first causing the reciprocating pressing component to move upward. The inclined wall of the first chute pushes the sliding column upward, and the moving block moves upward along the first chute at the same time, thus enabling the reciprocating pressing component to move upward. When the moving block moves to the intersection of the first chute and the transverse chute, the sliding column is located at the intersection of the first chute and the second chute. The power unit continues to push the moving plate to move, and at this time, the wall of the second chute pushes the sliding column to move. The moving block enters the transverse chute simultaneously, and the transverse chute guides the moving block to move along a direction perpendicular to the driving direction. The sliding column can then drive the reciprocating pressing component to move along a direction perpendicular to the driving direction. At this time, the sliding column remains at the intersection of the first chute and the second chute. When the moving block moves to the intersection of the transverse chute and the second chute, the inclined wall of the second chute constrains the sliding column to move downward. The moving block slides down synchronously following the movement of the moving plate, and the sliding column drives the reciprocating pressing component to move downward, thus enabling the reciprocating pressing component to move along a direction perpendicular to the driving direction. When the moving plate returns, the inclined wall of the second sloping chute drives the sliding column to move upward, and the moving block moves upward along the second sloping chute until it reaches the intersection of the second sloping chute and the transverse chute. This drives the reciprocating pressing component to move upward. The power component continues to pull the moving plate back, and the sliding column pulls the moving block along the transverse chute until it reaches the intersection of the transverse chute and the first sloping chute. The moving plate continues to return, and the sliding column moves downward along the first sloping chute. The sliding column drives the moving block to move into the first sloping chute. This can drive the reciprocating pressing component to move downward, thereby increasing the compaction width of the slope, avoiding the need for vehicles to move back and forth to compact the slope, and improving construction efficiency.

[0011] In one specific implementation, the power assembly includes a drive motor mounted on a frame, a rotating shaft coaxially mounted on the drive motor, a swing arm mounted on the rotating shaft, and a rocking rod rotatably mounted on the swing arm, the other end of which is rotatably connected to a moving plate.

[0012] During operation, the drive motor drives the rotating shaft and the swing arm to rotate in a circular motion, which in turn drives the swing arm to swing in a plane. The swing arm drives the moving plate to move horizontally and linearly along the guide rail through the pushing and pulling force. The entire motion process is a uniform and continuous motion without sudden stops or sudden changes in force.

[0013] In one specific implementation, the reciprocating pressing assembly includes a drive hydraulic cylinder connected to a moving rod, the piston rod of the drive hydraulic cylinder being provided with a connecting frame, and the connecting frame being provided with a pressure plate.

[0014] The hydraulic cylinder drives the connecting frame to move down, and the pressure plate presses onto the slope. The hydraulic cylinder then drives the pressure plate to move up, and the vehicle moves the pressure plate, thus compacting the slope.

[0015] In one specific implementation, the connecting frame includes a connecting plate connected to the piston rod of a driving hydraulic cylinder. A Y-shaped frame is provided on the connecting plate, with a cross rotatably connected to each of the two free ends of the Y-shaped frame. The cross rotates around the Y-shaped frame. A swing frame is rotatably connected to each of the two free ends of the cross, and the swing frame is rotatably connected to a pressure plate. The swing frame rotates along the cross, and the rotation center axis of the swing frame is perpendicular to the rotation center axis of the cross. Two swing hydraulic cylinders are provided on the connecting plate. The cylinder body of the swing hydraulic cylinder is connected to the ball joint of the connecting plate. The piston rod end wall of the swing hydraulic cylinder is connected to the ball joint of the swing frame. One connection point between the piston rod end wall of the swing hydraulic cylinder and the swing frame is collinear with the rotation center axis of the cross, and the other connection point is collinear with the rotation center axis of the swing frame.

[0016] Ideally, the slope's inclination angle should be consistent along the direction of travel. However, in actual engineering projects, due to varying terrain, especially in mountainous road construction, there may be an angle difference between the slope's start and end points to ensure driving safety and smooth drainage. Alternatively, on the outer side of a curve, the slope may have a gradually decreasing angle from start to end to accommodate factors such as vehicle centrifugal force. Therefore, to accommodate these angle changes at the slope's start and end, a swinging hydraulic cylinder drives a swinging frame to rotate around a cross, or the cross rotates around a Y-shaped frame, thereby adjusting the pressure plate's posture to adapt to the slope's angle variations.

[0017] In one specific implementation, the pressure plate is provided with a telescopic rod on the side near the swing frame, the swing frame is provided with a sleeve for the telescopic rod to slide, and the sleeve is provided with a shock-absorbing spring connected to the telescopic rod.

[0018] The vibration generated by the pressure plate compacting the slope is reduced by using shock-absorbing springs to reduce the possibility of damage to the pressure plate.

[0019] In this invention, the reciprocating compaction component automatically moves back and forth perpendicular to the driving direction during a single vehicle journey, thereby expanding the width of the slope compacted in a single pass. This avoids the need for traditional compaction devices to require multiple vehicle back-and-forth movements to complete the compaction of the entire slope width, significantly reducing operating time and labor costs, and substantially improving construction efficiency.

[0026] The following is in conjunction with the appendix Figure 1-5 The present invention will be described in further detail below.

[0027] Reference Figure 1 and Figure 2 A vehicle-mounted compaction device for roadbed slopes includes a frame 1 articulated on a vehicle. The frame 1 and the vehicle are connected by a hydraulic cylinder 2. The frame 1 includes a bracket 32 ​​connected to the vehicle and a driven frame 33 articulated to the bracket 32. The cylinder body of the hydraulic cylinder 2 is articulated to the vehicle, and the end wall of the piston rod of the hydraulic cylinder 2 is articulated to the driven frame 33. By driving the driven frame 33 to rotate through the hydraulic cylinder 2, it can adapt to slopes of different gradients.

[0028] The driven frame 33 is equipped with a power component 3 and a reciprocating sliding component 4. The power component 3 drives the reciprocating sliding component 4 to move back and forth. The reciprocating sliding component 4 moves back and forth along a direction perpendicular to the travel direction. The reciprocating sliding component 4 is equipped with a reciprocating pressing component 5, which is used to compact the slope.

[0029] Reference Figure 2The power assembly 3 includes a drive motor 18 mounted on the driven frame 33. The axis of the drive motor 18 is parallel to the driving direction of the vehicle. The drive motor 18 is coaxially mounted on a rotating shaft 31. The rotating shaft 31 is equipped with a swing rod 19, which is arranged radially along the rotating shaft 31. A rocker arm 20 is rotatably mounted on the swing rod 19. The other end of the rocker arm 20 is rotatably connected to the moving plate 7. The power assembly converts the circular rotational motion of the drive motor 18 into the horizontal linear reciprocating motion of the moving plate 7 along the guide rail 6 through a crank-rocker mechanism of "rotating shaft-swing rod-rocker arm". The rotation radius of the rocker arm 19 determines the reciprocating stroke of the moving plate, ensuring precise and controllable stroke.

[0030] The reciprocating sliding assembly 4 includes a movable plate 7, which is rotatably connected to the rocker arm 20. A guide rail 6 is provided on the frame 1. In this embodiment, the guide rail 6 is a plate with a dovetail groove shape. The guide rail 6 is set perpendicular to the travel direction. The movable plate 7 moves within the guide rail 6. In this embodiment, the direction in which the movable plate 7 moves within the sliding 6 is the moving direction, which is perpendicular to the travel direction. A pushing inclined groove 8 is provided through the movable plate 7. A moving groove 9 is provided through the bottom wall of the groove of the guide rail 6. When the movable plate 7 slides on the guide rail 6, the pushing inclined groove 8 and the moving groove 9 always have a partial projection overlap along the travel direction. The overlapping area meets the assembly requirements of the sliding column 10 and the moving block 11 simultaneously entering the two grooves, ensuring the synchronous movement of the sliding column 10 and the moving block 11.

[0031] The reciprocating sliding assembly 4 also includes a moving rod 34, which is located on the side of the moving plate 7 away from the moving groove 9. The end of the moving rod 34 is provided with a core rod, the axis of which is parallel to the driving direction of the vehicle. The core rod passes through both the pushing inclined groove 8 and the moving groove 9. A sliding column 10 is coaxially provided on the core rod and located in the pushing inclined groove 8. The diameter of the sliding column 10 is smaller than the groove width of the pushing inclined groove 8. The sliding column 10 and the core rod are rotatably connected. A moving block 11 is coaxially provided on the core rod. In this embodiment, the moving block 11 is a cube, and the outer diameter of the sliding column 10 is equal to the width of the moving block 11. In other embodiments, both the sliding column 10 and the moving block 11 can be rollers.

[0032] The sliding column 10 slides within the sliding groove 8, and the moving block 11 slides within the moving groove 9. Both ends of the core rod are provided with limiting blocks 12. The two limiting blocks 12 clamp the sliding column 10 and the moving block 11 within the sliding groove 8 and the moving groove 9. One limiting block 12 is in contact with the surface of the moving plate 7, and the other limiting block 12 is located on the side of the guide rail 6 away from the moving plate 7. The limiting blocks 12 prevent the sliding column 10 and the moving block 11 from coming out of the groove, and also limit the sliding column 10 and the moving block 11 to slide along the groove without axial movement, thus ensuring the stability of the movement.

[0033] The sliding groove 8 constrains the sliding column 10, causing the moving block 11 to slide along the moving groove 9. The moving rod 34 is connected to the reciprocating downward pressing assembly 5. Specifically, the sliding column 10, the moving block 11, and the core rod are coaxially fixed, and the core rod is rigidly connected to the moving rod 34, forming a rigid moving body. The groove wall of the sliding groove 8 directly acts on the sliding column 10, determining its possible direction of movement along the groove direction; while the moving block 11 is strictly confined within the moving groove 9, and its movement is limited to the path of the moving groove 9. Therefore, when the horizontal movement of the moving plate 7 forces the sliding column 10 to move perpendicular to the direction of movement through the inclined surface of the sliding groove 8, this tendency must be realized by the sliding of the moving block 11 in the corresponding vertical section of the moving groove 9, either the first groove 15 or the second groove 17. Conversely, when the moving block 11 is located in the horizontal section of the moving groove 9, the transverse groove 16, it cannot move vertically, thus forcing the sliding column 10 to remain in the lowest point area of ​​the V-shaped groove, only making horizontal movements. This coupling relationship of 'channel wall constraint - rigid transmission' is the fundamental guarantee that the mechanism runs accurately along the designed trajectory without jamming.

[0034] Reference Figure 3 In this embodiment, the direction perpendicular to the moving direction is the height direction. The pushing chute 8 is composed of a first chute 13 and a second chute 14. The first chute 13 and the second chute 14 are interconnected and form a V-shaped groove, that is, the angle between the extension direction of the first chute 13 and the moving direction is an acute angle, and the angle between the extension direction of the second chute 14 and the moving direction is an obtuse angle. The moving groove 9 includes a first sliding groove 15, a transverse groove 16, and a second sliding groove 17. The transverse groove 16 is located between the first sliding groove 15 and the second sliding groove 17. The transverse groove 16 is connected to the first sliding groove 15 and the second sliding groove 17. The first sliding groove 15 and the second sliding groove 17 are both arranged along the height direction, and the transverse groove 16 is arranged along the moving direction. The diameter of the sliding column 10 is smaller than the width of the transverse groove 16 along the height direction. The width of the moving block 11 is... The width of the moving block 11 is equal to the width of the moving groove 9. Those skilled in the art will understand that, in order to facilitate the movement of the moving block 11, reduce friction, and prevent jamming, the width of the moving block 11 is set to be slightly smaller than the width of the first sliding groove 15 and the second sliding groove 17 in the moving direction. The height of the moving block 11 is slightly smaller than the width of the horizontal groove 16 in the height direction. The first sliding groove 15, the horizontal groove 16, and the second sliding groove 17 form a C-shaped groove. The opening direction of the C-shaped groove is the same as the opening direction of the V-shaped groove, that is, both opening towards the ground. The intersection point of the first inclined groove 13 and the second inclined groove 14 includes the highest point and the lowest point. The lowest point is set on the side closer to the ground, and the highest point is set on the side farther from the ground from the lowest point. The height of the groove wall of the horizontal groove 16 on the side closer to the ground is the same as the height of the lowest point.

[0035] Those skilled in the art will understand that the maximum horizontal travel of the movable plate 7 along the guide rail 6 is S=2R (R is the rotation radius of the swing rod 19, i.e., the distance from the center of the rotating shaft 31 to the connection point between the swing rod 19 and the rocker arm 20), that is, S= the length of the transverse groove 16= the length of the moving block 11 in the transverse groove 16, ensuring that the movable block 11 can complete the entire horizontal sliding within the transverse groove 16, and that the sliding column 10 can complete the complete action of "upward movement-horizontal movement-downward movement" within the V-shaped groove of the pushing inclined groove 8; The power component 3 drives the moving plate 7 to move horizontally back and forth along the guide rail 6. The movement of the moving plate 7 provides the only power input for the reciprocating sliding component 4. The direction and speed of the moving plate 7 determine the direction and speed of the movement of the sliding column 10 and the moving block 11. The two achieve precise motion synchronization without power delay or coordination deviation.

[0036] When the moving plate 7 moves along the guide rail 6 from the side closest to the vehicle to the side furthest from the vehicle, the sliding column 10 and the moving block 11 first move from the bottom of the first groove 15 and the first inclined groove 13 (i.e., the side closest to the ground) along the height direction towards the side of the transverse groove 16. As the moving plate 7 moves towards the side of the second groove 17, the moving block 11 is clamped in the first groove 15. Therefore, the two inclined walls of the first inclined groove 13 on the moving plate 7 can push the sliding column 10 towards the side of the transverse groove 16. The sliding column 10 then slides along the inclined wall of the first inclined groove 13 towards the lowest point, thus realizing the upward movement of the sliding column 10. This, in turn, drives the moving block 11 to move along the groove wall of the first groove 15 towards the transverse groove 16. The sliding column 10 continues to slide until it reaches the junction of the first inclined groove 13 and the second inclined groove 14, i.e., between the highest and lowest points. The height of the groove wall near the ground is the same as the height of the lowest point, so the moving block 11 can move into the transverse groove 16. The moving block 11 enters the transverse groove 16 along the groove wall of the first sliding groove 15. Since the moving block 11 slides along the length of the transverse groove 16 (i.e., along the guide rail 6), the moving block 11 does not change in the height direction, so it can move along the transverse groove 16 with the sliding column 10 and the moving plate 7. When the moving block 11 encounters the second sliding groove 17, the moving block 11 loses the support of the groove wall of the transverse groove 16 and will tend to slide into the second sliding groove 17. At the same time, the sliding column 10 can slide into the second inclined groove 14. The sliding column 10 and the moving block 11 can slide down along the second inclined groove 14 and the second sliding groove 17 respectively, so that the moving plate 7 can move in the guide rail 6.

[0037] When compacting the roadbed, the reciprocating compaction assembly 5 first needs to move upward. Therefore, the drive motor 18 drives the rotating shaft 31 and the swing rod 19 to rotate, which in turn drives the swing rod 20 to swing, thus pushing the moving plate 7 to slide along the guide rail 6. Specifically, the swing rod 20 first pushes the moving plate 7 along the guide rail 6 towards the side away from the vehicle. The rotating shaft 31 then drives the swing rod 19 to rotate to the side of the drive motor 18 closer to the vehicle. The rotating shaft 31 continues to rotate towards the ground, thus pushing the end of the swing rod 19 to rotate towards the side away from the vehicle. This pushes the swing rod 20 and the moving plate 7 along the guide rail 6 towards the side away from the vehicle. The inclined wall of the first inclined groove 13 pushes the sliding column 10 upward, and the moving block 11 simultaneously moves upward along the first sliding groove 15, thereby enabling the reciprocating compaction assembly 5 to move upward. When the moving block 11 moves to the first sliding groove 15... At the intersection of the transverse groove 16 and the horizontal groove 17, the sliding column 10 is located at the intersection of the first inclined groove 13 and the second inclined groove 14. The power component 3 continues to push the moving plate 7 to move. At this time, the groove wall of the second inclined groove 14 pushes the sliding column 10 to move. The moving block 11 enters the transverse groove 16 at the same time. The transverse groove 16 guides the moving block 11 to move along the moving direction. The sliding column 10 can thus drive the reciprocating pressing component 5 to move at the same time. At this time, the sliding column 10 is continuously at the intersection of the first sliding groove 15 and the second sliding groove 17. When the moving block 11 moves to the intersection of the transverse groove 16 and the second sliding groove 17, the sliding column 10 is constrained to move down by the inclined wall of the second inclined groove 14. The moving block 11 moves down along the moving plate 7 at the same time. The sliding column 10 drives the reciprocating pressing component 5 to move down. In this way, the reciprocating pressing component 5 can be driven to move along a direction perpendicular to the driving direction. When the moving plate 7 returns, the inclined wall of the second inclined groove 14 drives the sliding column 10 to move upward, and the moving block 11 moves upward along the second chute 17 until it reaches the intersection of the second chute 17 and the transverse groove 16, thereby driving the reciprocating pressing component 5 to move upward. The power component 3 continues to pull the moving plate 7 back, and the sliding column 10 pulls the moving block 11 to move along the transverse groove 16 until it reaches the intersection of the transverse groove 16 and the first chute 15. The moving plate 7 continues to return, and the sliding column 10 moves downward along the first inclined groove 13, thereby driving the moving block 11 to move into the first chute 15. This can drive the reciprocating pressing component 5 to move downward, thereby increasing the width of the slope to be compacted, avoiding the need for vehicles to move back and forth to compact the slope, and improving construction efficiency.

[0038] In summary, those skilled in the art will understand that the compaction cycle of this compaction device is as follows: Step 1 (Lifting and Outward Lateral Movement Starting Point): The power component 3 drives the moving plate 7 to move outward → the sliding column 10 is pushed upward by the inclined wall of the first inclined groove 13 → the moving block 11 is coupled and moves upward along the first sliding groove 15 → driving the reciprocating downward pressing component 5 to lift and reach the outer starting height.

[0039] Step 2 (Horizontal outward movement): The sliding column 10 moves to the lowest point of the V-groove → the moving block 11 moves synchronously to the starting end of the transverse groove 16 → the moving plate 7 continues to move outward → the moving block 11 is restricted to pure horizontal movement within the transverse groove 16 → the sliding column 10 slides horizontally in the area of ​​the lowest point of the V-groove → the reciprocating pressing component 5 moves outward purely laterally to compact the new area of ​​the slope.

[0040] Step 3 (End of descent and compaction): The moving block 11 moves to the junction of the transverse groove 16 and the second slide groove 17 → the sliding column 10 is guided by the inclined wall of the second inclined groove 14 to begin to descend → the moving block 11 descends along the second slide groove 17 → the reciprocating pressing component 5 descends to the initial height inside, completing one outward 'lifting-outward transverse movement-descent' cycle.

[0041] Step 4 (Return to Cycle): The power component 3 reverses, and the above process is reversed to realize the 'lifting-inward lateral movement-lowering' return cycle of the reciprocating pressing component 5.

[0042] Through this cycle, the reciprocating pressing component 5 automatically completes the reciprocating widening and compaction perpendicular to the driving direction while the vehicle is traveling in a straight line, without the need for the vehicle to turn around.

[0043] The reciprocating downward pressing assembly 5 includes a drive hydraulic cylinder 21 connected to the moving rod 34. The axis of the drive hydraulic cylinder 21 is perpendicular to the axis of the moving rod 34. A connecting frame is provided on the piston rod of the drive hydraulic cylinder 21. Specifically, the connecting frame includes a connecting plate 23 connected to the piston rod of the drive hydraulic cylinder 21. A Y-shaped frame 24 is provided on the connecting plate 23. A cross 25 is rotatably connected to the two free ends of the Y-shaped frame 24. The cross 25 rotates around the two free ends of the Y-shaped frame 24. A swing frame 26 is rotatably connected to the two free ends of the cross 25. The swing frame 26 moves along the cross... The two free ends of the frame 25 rotate, and the rotation center axis of the swing frame 26 is perpendicular to the rotation center axis of the cross 25. Two swing hydraulic cylinders 27 are provided on the connecting plate 23. The cylinder body of the swing hydraulic cylinder 27 is connected to the ball head of the connecting plate 23. The piston rod end wall of the swing hydraulic cylinder 27 is connected to the ball head of the swing frame 26. One connection point between the piston rod end wall of the swing hydraulic cylinder 27 and the swing frame 26 is collinear with the rotation center axis of the cross 25, and the other connection point between the piston rod end wall of the swing hydraulic cylinder 27 and the swing frame 26 is collinear with the rotation center axis of the swing frame 26.

[0044] Reference Figure 4 A pressure plate 22 is slidably mounted on the swing frame 26. Specifically, a sleeve rod 30 is provided on the side of the swing frame 26 away from the Y-shaped frame 24, and a telescopic rod 28 is provided on the pressure plate 22 that slides within the sleeve rod 30. A shock-absorbing spring 29 connected to the telescopic rod 28 is provided inside the sleeve rod 30.
