[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] 1. The machine frame is equipped with a roller, a traveling device, and a body posture detector. It is understood that, to meet different operational needs, the roller can be made of plain steel wheels, spur wheels, mesh wheels, or rubber tires. Meanwhile, the traveling device typically uses wide-base tires with engineering machinery tread patterns such as L-2, L-3, L-4, and L-5 to provide sufficient grip and prevent vehicle rollover. In addition, the body posture detector can use a level sensor or install a pressure sensor between the machine body and the traveling wheel drive shaft to detect the pressure between them.

[0021] 2. The roller balancing assembly is installed at the pivot end of the roller to balance the pressure on both ends of the roller. Obviously, when the roller travels to uneven or rugged road sections, the roller is prone to tilting due to uneven force, resulting in uneven ground pressure and affecting the compaction quality. At this time, the roller balancing assembly is needed to balance the force on both sides of the roller to ensure that the road surface to be compacted is evenly compressed, thereby ensuring the compaction quality.

The machine body balancing assembly is installed on the frame; the machine body balancing assembly includes a swing-type machine body center of gravity adjustment assembly, a drive swing arm, and a rotation drive device; the drive swing arm is pivotally connected to the frame; the swing-type machine body center of gravity adjustment assembly is sleeved on the drive swing arm; the rotation drive device is installed on the frame and drives the drive swing arm so that the swing-type machine body center of gravity adjustment assembly can rotate relative to the frame; it can be understood that when the road roller travels to a slope, due to the difference in weight between the roller and the frame, the center of gravity of the frame shifts; the swing-type machine body center of gravity adjustment assembly should normally be set at the rear end of the frame to balance the mass of the front and rear of the frame; when the center of the frame shifts left and right, the rotation drive device drives the drive swing arm to rotate and drives the swing-type machine body center of gravity adjustment assembly to swing in the opposite direction, thereby counteracting the tendency of the frame to tip over and balance the overall posture of the frame;

[0031] It should be noted that when an element is described as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is described as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0033] See Figures 1-5 An automatic leveling device for a road roller body for slope compaction according to a preferred embodiment of the present invention includes: a frame 1, a roller balancing assembly 2, a body balancing assembly 3, and a central control assembly.

[0034] The frame 1 is equipped with a roller 101, a traveling device 102, and a body posture detector 103. It is understood that, to meet different operational needs, the roller 101 can be made of plain steel wheels, spur wheels, mesh wheels, or rubber tires. Meanwhile, the traveling device 102 typically uses wide-base tires with engineering machinery tread patterns such as L-2, L-3, L-4, and L-5 to provide sufficient grip and prevent vehicle rollover. In addition, the body posture detector 103 can use a level sensor or install a pressure sensor between the body and the traveling wheel drive shaft to detect the pressure between them.

[0035] The roller balancing assembly 2 is installed at the pivot end of the roller 101 to balance the pressure on both ends of the roller 101. Obviously, when the roller travels to an uneven or rugged road section, the roller 101 is prone to tilting due to uneven force, resulting in uneven ground pressure and affecting the compaction quality. At this time, the roller balancing assembly 2 is needed to balance the force on both sides of the roller 101 to ensure that the road surface to be compacted is evenly compressed, thereby ensuring the compaction quality.

[0036] The machine body balancing assembly 3 is mounted on the frame 1; the machine body balancing assembly 3 includes a swing-type machine body center of gravity adjustment assembly 301, a drive swing rod 302, and a rotation drive device 303; the drive swing rod 302 is pivotally connected to the frame 1; the swing-type machine body center of gravity adjustment assembly 301 is sleeved on the drive swing rod 302; the rotation drive device 303 is mounted on the frame 1 and drives the drive swing rod 302, so that the swing-type machine body center of gravity adjustment assembly 301 can rotate relative to the frame 1; it can be understood that when the road roller is traveling... When approaching a slope, the center of gravity of the frame 1 shifts due to the weight difference between the roller 101 and the frame 1. The swing-type body center of gravity adjustment component 301 should normally be positioned at the rear end of the frame 1 to balance the mass of the front and rear ends of the frame 1. When the center of the frame 1 shifts left or right, the rotary drive device 303 drives the drive swing arm 302 to rotate and causes the swing-type body center of gravity adjustment component 301 to swing in the opposite direction, thereby counteracting the tendency of the frame 1 to tip over and balancing the overall posture of the frame 1.

[0037] The central control component is installed on the frame 1. The central control component is electrically connected to the fuselage attitude detector 103, the roller balancing component 2, and the rotation drive device 303, and can control the roller balancing component 2 and the rotation drive device 303 through the electrical signals of the fuselage attitude detector 103. Obviously, the central control component is used to process the information from the fuselage attitude detector 103 and convert it into electrical signals to drive the roller balancing component 2 and the rotation drive device 303 to work, thereby improving the working response speed of the swing-type fuselage center of gravity adjustment component 301 and the roller balancing component 2, so as to adjust the center of gravity of the whole machine in a timely manner.

[0038] When the road roller travels to a rough area, the body posture detector 103 detects that the two ends of the roller 101 are at different heights and transmits this information to the central control component for processing. At this time, the roller balancing component 2 responds to the electrical signal from the central control component and begins to adjust the force on both sides of the roller 101 until the force on both sides of the roller 101 is balanced and maintained. When the central control component receives a signal from the body posture detector 103 that the frame 1 has a tendency to overturn or tip over, the rotary drive device 303 responds to the signal and drives the drive swing arm 302 to adjust the tilt angle of the swing-type body center of gravity adjustment component 301 to adjust the center of gravity of the frame 1, thereby counteracting the tendency of the frame 1 to overturn.

[0039] The frame 1 is equipped with a roller 101, a traveling device 102, and a body posture detector 103. It is understood that, to meet different operational needs, the roller 101 can be made of plain steel wheels, spur wheels, mesh wheels, or rubber tires. Meanwhile, the traveling device 102 typically uses wide-base tires with engineering machinery tread patterns such as L-2, L-3, L-4, and L-5 to provide sufficient grip and prevent vehicle rollover. In addition, the body posture detector 103 can use a level sensor or install a pressure sensor between the body and the traveling wheel drive shaft to detect the pressure between the two.

[0040] The roller balancing assembly 2 is installed at the pivot end of the roller 101 to balance the pressure on both ends of the roller 101. Obviously, when the roller travels to an uneven or rugged road section, the roller 101 is prone to tilting due to uneven force, resulting in uneven ground pressure and affecting the compaction quality. At this time, the roller balancing assembly 2 is needed to balance the force on both sides of the roller 101 to ensure that the road surface to be compacted is evenly compressed, thereby ensuring the compaction quality.

[0041] The machine body balancing assembly 3 is mounted on the frame 1; the machine body balancing assembly 3 includes a swing-type machine body center of gravity adjustment assembly 301, a drive swing rod 302, and a rotation drive device 303; the drive swing rod 302 is pivotally connected to the frame 1; the swing-type machine body center of gravity adjustment assembly 301 is sleeved on the drive swing rod 302; the rotation drive device 303 is mounted on the frame 1 and drives the drive swing rod 302, so that the swing-type machine body center of gravity adjustment assembly 301 can rotate relative to the frame 1; it can be understood that when the road roller travels to When on a slope, the center of gravity of the frame 1 shifts due to the weight difference between the roller 101 and the frame 1. The swing-type body center of gravity adjustment component 301 should normally be set at the rear end of the frame 1 to balance the mass of the front and rear of the frame 1. When the center of the frame 1 shifts to the left or right, the rotary drive device 303 drives the drive swing rod 302 to rotate and drives the swing-type body center of gravity adjustment component 301 to swing in the opposite direction, thereby counteracting the tendency of the frame 1 to tip over and balance the overall posture of the frame 1.

[0042] The central control component is installed on the frame 1; the central control component is electrically connected to the fuselage attitude detector 103, the roller balancing component 2, and the rotation drive device 303, and can control the roller balancing component 2 and the rotation drive device 303 through the electrical signal of the fuselage attitude detector 103; obviously, the central control component is used to process the information from the fuselage attitude detector 103 and convert it into electrical signals to drive the roller balancing component 2 and the rotation drive device 303 to work, thereby improving the working response speed of the swing-type fuselage center of gravity adjustment component 301 and the roller balancing component 2, so as to adjust the center of gravity of the whole machine in a timely manner.

[0043] See Figures 1-3 Preferably, the frame 1 is provided with a roller mounting frame 104, and a drive groove 105 is formed on one side wall of the roller mounting frame 104. The drive groove 105 extends along the height direction of the roller mounting frame 104. The drive end of the roller balancing assembly 2 is slidably nested in the drive groove 105 so as to be close to or away from the ground surface. The road roller 101 includes a drive shaft 107 and a roller body 106. The drive shaft 107 is slidably inserted into the roller body 106. The two ends of 7 are respectively hinged to the inner wall of the roller mounting frame 104 and the hinge end of the roller balancing assembly 2, so that the roller body 106 can swing relative to the roller mounting frame 104; the roller mounting frame 104 is used to protect the periphery of the roller 101; in addition, the drive groove 105 is used to limit and regulate the adjustment movement trend of the roller balancing assembly 2; at the same time, the drive shaft 107 is slidably inserted into the roller 101 to make way for the adjustment of the roller 101.

[0044] See Figure 3Preferably, the roller balancing assembly 2 includes a drive slider 201, a linear drive device 202, and an elastic anti-compression assembly 4; the drive slider 201 is slidably nested within the drive groove 105; the hinged end of the drive shaft 107 is hinged to the drive slider 201; the linear drive device 202 is mounted on the roller mounting frame 104 and drives the drive slider 201 so that the drive shaft 107 can approach or move away from the ground surface; the roller body 106, the elastic anti-compression assembly 4, and the roller mounting frame are also included. The inner wall of 104 is arranged sequentially from the inside to the outside along the radial direction of the roller mounting frame 104 to weaken the vibration transmission between the roller mounting frame 104 and the drive shaft 107. Obviously, with this arrangement, the linear drive device 202 can apply pressure or depressurize the drive slider 201 in a timely manner, thereby improving the balance speed of the roller 101. In addition, the elastic anti-compression component 4 is used to separate the drive shaft 107 and the roller mounting frame 104 to avoid damage to the components caused by overly rigid connection between the two.

[0045] See Figure 3 Preferably, the elastic anti-compression component 4 includes an elastic mounting plate 401; the elastic mounting plate 401 is provided with a mounting part 402 and a buffer part 403 connected in sequence; the mounting part 402 is mounted on the inner wall of the roller mounting frame 104; the buffer part 403 is spaced apart from the inner wall of the roller mounting frame 104 to form a buffer space 404; the buffer part 403 is provided with a clearance groove 405, the clearance groove 405 extends along the height direction of the roller mounting frame 104 and is correspondingly provided with the drive slide groove 105. The hinged end of the drive shaft 107 passes through the clearance groove 405, and the outer wall of the drive shaft 107 abuts against the buffer part 403. Obviously, with this arrangement, when the road roller 101 is impacted, the elastic mounting plate 401 can deform in time to release stress, thereby preventing the vibration from being transmitted to the frame 1 and affecting the operation of the body attitude detector 103. At the same time, due to the existence of the buffer space 404, the collision between the drive shaft 107 and the roller mounting frame 104 can be avoided when the drive shaft 107 is pulled by the drive slider 201.

[0046] See Figure 3 Preferably, the elastic anti-compression component 4 further includes an elastic recovery element 406; the elastic recovery element 406 is installed on the inner wall of the roller mounting frame 104 and accommodated in the buffer space 404; the two ends of the elastic recovery element 406 abut against the roller mounting frame 104 and the buffer portion 403 respectively, so that the buffer portion 403 has a tendency to move away from the roller mounting frame 104; it can be understood that the elastic recovery element 406 can be selected from components such as compression springs, silicone pads and electromagnets.

[0047] See Figure 3 Preferably, at least two drive grooves 105 are provided, and the two drive grooves 105 are arranged opposite to each other; at least two drive sliders 201 are provided, and the two drive sliders 201 are respectively slidably nested in one of the drive grooves 105; at least two drive shafts 107 are provided, and the hinged ends of the two drive shafts 107 are respectively hinged to one of the drive sliders 201, and the two drive shafts 107 are respectively slidably inserted into the opposite ends of the roller body 106; at least two linear drive devices 202 are provided, and the two linear drive devices 202 are respectively driving and connected to one of the drive sliders 201; multiple elastic recovery components are provided, and the multiple elastic recovery components are distributed at intervals along the height direction of the roller mounting frame 104, at intervals along the width direction of the roller mounting frame 104, and are arranged opposite to each other along the length direction of the roller mounting frame 104; obviously, such an arrangement can further improve the adjustment speed of the roller balancing component 2 and at the same time improve its structural stability.

[0048] See Figure 4 Preferably, the driving end of the driving slider 201 is provided with at least two mounting grooves 203, which are arranged opposite each other along the radial direction of the driving slider 201; the linear drive device 202 includes at least two hydraulic cylinders, the driving ends of the two hydraulic cylinders are mounted on the outer wall of the roller mounting frame; the output end of each hydraulic cylinder is provided with an elastic abutment 204, and the two elastic abutment 204 are respectively accommodated in one of the mounting grooves 203; it can be understood that the elastic abutment 204 of the two hydraulic cylinders simultaneously control the linear movement of the driving slider 201. This arrangement not only improves the stability of the overall structure, but also increases the overall output torque of the device by "pushing while pulling".

[0049] See Figure 2Preferably, the frame 1 is provided with a receiving space 108, and the fuselage balancing assembly 3 is housed within the receiving space 108; the frame 1 has an object inlet / outlet 109, the two ends of which are respectively connected to the receiving space 108 and the external environment; the fuselage balancing assembly 3 also includes a sealing member 310, which seals the object inlet / outlet 109; the rotary drive device 303 is installed on the sealing member 310 and drives one end of the drive swing rod 302, the other end of which is pivotally connected to the inner wall of the receiving space 108; it can be understood that in order to make the frame 1 more compact, the fuselage balancing assembly 3 should be housed through the receiving space 108; obviously, this arrangement can also keep the center of gravity at a relatively low position, thereby improving the grip of the frame 1.

[0050] See Figure 5 Preferably, the swingable fuselage center of gravity adjustment assembly 301 includes a limiting sleeve 304 and a housing 305 connected in sequence; one of the limiting sleeve 304 and the driving swing rod 302 is provided with a guide groove, and the other is provided with a guide protrusion. The guide protrusion slides in cooperation with the guide groove to limit the swing of the limiting sleeve 304 relative to the driving swing rod 302; the housing 305 is provided with a receiving cavity 306 and a filling inlet 307; the receiving cavity 306 is used to receive the filling material; the two ends of the filling inlet 307 are respectively connected to the receiving cavity 306 and the receiving space 108; it can be understood that the filling material in the housing 305 can be filled with liquid or a fluid solid (such as sand); obviously, the center of gravity of a fluid substance can change at any time, which can more effectively improve the grip of the frame 1 than a solid, thereby avoiding the frame 1 from tipping over due to excessive reverse swing angle of the housing 305.

[0051] See Figure 5 Preferably, multiple swingable fuselage center of gravity adjustment components 301 are provided, and the multiple swingable fuselage center of gravity adjustment components 301 are arranged sequentially along the length direction of the drive swing rod 302; the two opposite ends of the limiting sleeve 304 are respectively provided with connecting end 308 and connecting end 309; in two adjacent swingable fuselage center of gravity adjustment components 301, the connecting end 308 of the limiting sleeve 304 of one is connected to the connecting end 309 of the limiting sleeve 304 of the other; obviously, such an arrangement can further stabilize the center of gravity of the frame 1, thereby preventing the frame 1 from tipping over.
