Description

TECHNICAL FIELD

[0001] The present application relates to the asphalt paving technology field, more particularly, to an asphalt pavement tamping equipment. BACKGROUND

[0002] Asphalt pavement is a kind of pavement formed by paving and tamping asphalt concrete. After forming, the pavement is flat, dense, less dusty, and has certain roughness, so it has good driving comfort and appearance, and has good aging resistance, wear resistance, temperature stability and resistance to driving damage.

[0003] The asphalt pavement tamping equipment is usually composed of a frame, a rolling cylinder, an engine and a hydraulic system. The asphalt pavement tamping equipment uses the gravity of the rolling cylinder to apply pressure to the asphalt layer, so that the soft asphalt concrete layer becomes flat and dense. According to different construction needs, the asphalt pavement tamping equipment can be divided into static pressure type, vibration type, vibration-static pressure type and other types. Among them, the vibration type asphalt pavement tamping equipment can more effectively compact the asphalt pavement.

[0004] Some related pavement tamping equipment can better fit the pavement and achieve good tamping effect in straight sections, but in pavement turning sections, especially in the terrain where the turning section is low inside and high outside, not only is the rolling cylinder inconvenient to turn, but also the rolling cylinder cannot well fit the pavement, resulting in poor tamping effect. SUMMARY

[0005] In view of the problem that some related pavement tamping equipment not only is inconvenient to turn in pavement turning sections, especially in the terrain where the turning section is low inside and high outside, but also cannot well fit the pavement, resulting in poor tamping effect, the present application proposes an asphalt pavement tamping equipment and adopts the following technical solutions.

[0006] An asphalt pavement tamping equipment, comprising a main body, a transverse connecting piece, a first telescopic power device, a connector, two elastic pieces, a first longitudinal connecting piece, a second longitudinal connecting piece, a rolling cylinder, a first transverse arm and a second transverse arm.

[0007] A vertical hole is arranged on the main body, the transverse connecting piece passes through the vertical hole, and both ends of the transverse connecting piece pass out of the vertical hole.

[0008] The upper ends of the two elastic pieces are fixed to the two sides of the main body, and the lower ends are respectively connected to the parts of the transverse connecting piece that bidirectionally extend out of the vertical hole.

[0009] One of the first telescopic power device and the connector is hinged to one end of the transverse connecting piece and can rotate in the horizontal plane relative to the transverse connecting piece, and the other is fixed to the other end of the transverse connecting piece.

[0010] The first telescopic power device has a first telescopic shaft. One end of the first longitudinal connecting member is fixedly connected to the first telescopic shaft, and the other end is hingedly connected to the first transverse arm.

[0011] One end of the second longitudinal connecting member is fixedly connected to the connector, and the other end is hingedly connected to the second transverse arm.

[0012] The first transverse arm and the second transverse arm are rotationally connected to the two ends of the rolling cylinder.

[0013] By adopting the above technical scheme, one of the first telescopic power device and the connector is hingedly connected to one end of the transverse connecting member, and can rotate in the horizontal plane relative to the transverse connecting member, and the other is fixedly connected to the other end of the transverse connecting member, one end of the first longitudinal connecting member is fixedly connected to the telescopic shaft of the first telescopic power device, and the other end is hingedly connected to the first transverse arm, one end of the second longitudinal connecting member is fixedly connected to the connector, and the other end is hingedly connected to the second transverse arm, and the first transverse arm and the second transverse arm are connected to the two ends of the rolling cylinder, which forms a three-point hinged structure for the rolling cylinder. Under the telescopic drive of the first telescopic power device, at least one end of the rolling cylinder is driven to move forward and backward relative to the other end, so that the rolling cylinder can rotate in the horizontal plane, so that at the turning place of the road surface, the turning of the rolling cylinder can be conveniently realized by the telescopic drive of the first telescopic power device. The road surface ramming device is also provided with two elastic members respectively connected to the parts of the transverse connecting member extending out of the vertical holes, which can be adjacent to the positions of the end portions of the transverse connecting member, and the two ends of the transverse connecting member are connected to the first telescopic power device and the connector, so that the first telescopic power device and the connector both have an active space for moving up and down. Since the first telescopic power device and the connector are respectively connected to the two ends of the rolling cylinder through the transmission mechanism, the two ends of the rolling cylinder have a high and low active space, so that the rolling cylinder can be well fitted to the road surface and present an inner low and outer high posture with the road surface, and thus the ramming effect is good.

[0014] As an improvement of the asphalt pavement ramming device, the connector is a second telescopic power device; the second telescopic power device has a second telescopic shaft arranged longitudinally, and the second telescopic shaft is fixedly connected to the second longitudinal connecting member.

[0015] By adopting the above technical scheme, the second telescopic power device can serve as a lateral connection to the transverse connecting member and a forward connection to the second longitudinal connecting member. The second telescopic power device can also drive the second longitudinal connecting member to move forward or backward, and in combination with the telescopic drive of the first telescopic power device, it can control one side to extend and the other side to shrink, which can more efficiently drive the rolling cylinder to turn than single-side control, and the turning control is more convenient.

[0016] As an improvement of the asphalt pavement tamping device, the width of the vertical hole and the width of the transverse connecting piece are equal, so that the transverse connecting piece is adapted to be inserted into the vertical hole and moves vertically along the vertical hole.

[0017] By adopting the above technical solution, the front and rear sides of the transverse connecting piece abut against the vertical hole, and when the asphalt pavement tamping device advances or reverses, the main body and the rolling cylinder can move synchronously through the abutting action. The transverse connecting piece only moves vertically along the vertical hole, so that the rolling cylinder does not move forward and backward through the vertical hole, but moves forward and backward at both ends only through the first telescopic power device or through the telescopic drive of the first telescopic power device and the connector, so that the first telescopic power device and the connector can control the rolling cylinder to accurately steer.

[0018] As an improvement of the asphalt pavement tamping device, the asphalt pavement tamping device comprises a first rotary driver and a rotary receiving piece. The first rotary driver comprises a first stator and a first rotary shaft. The first rotary shaft can rotate in place in the first stator. The first stator is fixed to the first transverse arm, and the first rotary shaft is fixed to one end of the rolling cylinder. The rotary receiving piece comprises a second stator and a second rotary shaft. The second rotary shaft can rotate in place in the second stator. The second stator is fixed to the second transverse arm. The second rotary shaft is connected to the other end of the rolling cylinder.

[0019] By adopting the above technical solution, the first transverse arm is indirectly connected to one end of the rolling cylinder through the first rotary driver, the second transverse arm is indirectly connected to the other end of the rolling cylinder through the rotary receiving piece, and the first rotary driver can also output power to drive the rolling cylinder to rotate in cooperation with the rotary receiving piece, thereby improving the power of the device on uphill and downhill. The first rotary driver is installed on the first transverse arm, and the first transverse arm can be hingedly moved relative to the first longitudinal connecting piece. The rotary receiving piece is installed on the second transverse arm, and the second transverse arm can be hingedly moved relative to the second longitudinal connecting piece. Therefore, the rolling cylinder can be steered by the first transverse arm and the second transverse arm.

[0020] As an improvement of the asphalt pavement tamping device, the rotary receiving piece is a second rotary driver or a bearing piece with the second rotary shaft.

[0021] By adopting the above technical solution, if the rotary receiving piece is a second rotary driver, the second rotary driver and the first rotary driver can be set to rotate synchronously to jointly drive the rolling cylinder to rotate, thereby improving the operation efficiency. If the rotary receiving piece is a bearing piece, the bearing receives the rotary motion at the other end through the rotary drive of the first rotary driver, so that the rolling cylinder is driven to rotate.

[0022] As an improvement of the asphalt pavement tamping device, the asphalt pavement tamping device further comprises a first inner shaft and a second inner shaft. The first rotating shaft is fixedly connected with the first inner shaft. The first inner shaft is fixed to a shaft center position of one end of the rolling cylinder. The shaft center of the first rotating shaft is parallel to the shaft center of the first inner shaft. The second rotating shaft is fixedly connected with the second inner shaft. The second inner shaft is fixedly connected to a shaft center position of the other end of the rolling cylinder. The shaft center of the second rotating shaft coincides with the shaft center of the first rotating shaft.

[0023] By adopting the above technical scheme, the first rotating driver can drive the first inner shaft to perform circumferential motion around the first rotating shaft, that is, eccentric rotation. Similarly, the second inner shaft and the first inner shaft perform synchronous eccentric rotation. By setting a smaller eccentric amplitude and a larger rotating speed, the first inner shaft and the second inner shaft can quickly perform small-amplitude circumferential motion, that is, vibration effect. Since the first inner shaft and the second inner shaft are both connected to the rolling cylinder, the rolling cylinder generates vibration motion effect.

[0024] As an improvement of the asphalt pavement tamping device, the asphalt pavement tamping device further comprises a first cylindrical block and a second cylindrical block. The first rotating shaft and the first inner shaft are respectively fixed in the two end faces of the first cylindrical block. The second rotating shaft and the second inner shaft are respectively fixed in the two end faces of the second cylindrical block.

[0025] By adopting the above technical scheme, the first rotating shaft and the first inner shaft are connected through the first cylindrical block, and the first rotating shaft and the first inner shaft are completely connected in the end faces of the first cylindrical block, so that the contact area is large and the structure is relatively firm. Similarly, the second rotating shaft and the second inner shaft are also completely connected in the end faces of the second cylindrical block, so that the contact area is large and the eccentric connection structure is relatively firm.

[0026] As an improvement of the asphalt pavement tamping device, the first cross arm, the first rotating shaft and the first cylindrical block are coaxial. The second cross arm, the second rotating shaft and the second cylindrical block are coaxial.

[0027] By adopting the above technical scheme, when the first rotating shaft rotates, the first cylindrical block only performs circumferential rotation motion, the motion amplitude is small, the motion is stable, and the operation stability of the connection structure is improved. The first cross arm and the first rotating shaft are coaxial, the influence of centrifugal force on the first cross arm is reduced, and the connection structure is relatively stable. Similarly, the connection structure of the second cross arm, the rotating connecting piece and the second cylindrical block is stable, and the operation stability is high.

[0028] As an improvement of the asphalt pavement tamping device, the first inner shaft and the second inner shaft are fixedly connected and integrally formed.

[0029] By adopting the technical scheme, the first inner shaft and the second inner shaft are connected and integrally formed, and two ends of the formed body are fixed in the interior of the rolling cylinder, so that the structure is more firm, and rotation is more synchronous and stable.

[0030] As an improvement of the asphalt pavement tamping device, the main body is a vehicle body. The vehicle body comprises a vehicle head, an outward expansion plate and a cab. The outward expansion plate is fixed to the bottom of the cab, and the outward expansion plate is above the vehicle head. The vehicle head is provided with the vertical hole. The upper ends of the two elastic members are fixed to the bottom surface of the outward expansion plate and are suspended on both sides of the vehicle head.

[0031] By adopting the technical scheme, the vehicle body can drive the rolling cylinder to advance or retreat. The elastic members are suspended on the bottom of the cab, and the vibration of the rolling cylinder is absorbed by the elastic members, so that the influence on the cab is small, and the driving comfort is improved.

[0032] In summary, the asphalt pavement tamping device has the following beneficial effects:

[0033] Under the driving of the first telescopic power device, the rolling cylinder rotates on the horizontal plane, so that the rolling cylinder of the asphalt pavement tamping device can be conveniently turned at the turning place of the road. The transverse connecting piece passes through the vertical hole, and the two elastic members respectively lift the transverse connecting piece. The two ends of the transverse connecting piece are connected with the first telescopic power device and the connector, so that the first telescopic power device and the connector both have the activity space of moving up and down. Since the first telescopic power device and the connector are indirectly connected with the two ends of the rolling cylinder, the two ends of the rolling cylinder have the activity space of moving up and down. Therefore, when the asphalt pavement tamping device is at the turning place of the road with the terrain of being low in the inside and high in the outside, the front rolling cylinder can be tilted relative to the rear main body, and the main body and the rolling cylinder can not be on the same plane, so that the rolling cylinder can well fit the road and present the posture of being low in the inside and high in the outside, and thus the rolling cylinder can better tamp the turning road with the posture of being low in the inside and high in the outside.

DETAILED DESCRIPTION

[0040] Some embodiments of the asphalt pavement compacting equipment are described in detail below with reference to the accompanying drawings.

[0041] Please refer to Figure 1 , an asphalt pavement compacting device, including a main body 1.

[0042] Please combine Figure 2 The asphalt pavement compacting equipment also includes a transverse connecting member 2, a first telescopic power device 3, and a connector 4.

[0043] Please combine Figure 3 The asphalt pavement compacting equipment also includes two elastic members 5 , a first longitudinal connecting member 6 , a second longitudinal connecting member 7 , a rolling cylinder 8 , a first cross arm 9 and a second cross arm 10 .

[0044] The main body 1 can be a vehicle body. A vertical hole 101 is provided on the main body 1, and the transverse connecting member 2 can be a straight rod. The transverse connecting member 2 passes through the vertical hole 101, and both ends of the transverse connecting member 2 pass through the vertical hole 101. If the interior of the main body 1 is solid, the vertical hole 101 can be a hole that passes through the main body 1 horizontally and has a vertical bar-shaped cross-section. If the interior of the main body 1 is a cavity, the vertical hole 101 can be a hole that penetrates the two side walls of the main body 1 and passes through the middle cavity at the same time, that is, only the two side walls are opened, and the openings on the two side walls are waist-shaped. Depending on whether the side walls are vertical walls, inclined walls, curved walls, etc., the openings are also in the form of corresponding vertical waist-shaped holes, inclined waist-shaped holes, or curved waist-shaped holes.

[0045] The elastic member 5 can be a spring and can be arranged vertically or tilted approximately vertically at an angle of 0-30 degrees. The upper ends of the two elastic members 5 are fixed to the sides of the main body 1, and the lower ends are connected to the two side rod sections of the horizontal connecting member 2 extending out of the vertical hole 101.

[0046] One of the first telescopic power unit 3 and the connector 4 is hinged to one end of the transverse connecting member 2, and can rotate in the horizontal plane relative to the transverse connecting member 2, and the other is fixed to the other end of the transverse connecting member 2, i.e. the first telescopic power unit 3 and the connector 4 are located on the two outer sides of the vertical hole 101. For example, the first telescopic power unit 3 is hinged to one end of the transverse connecting member 2 through a hinge shaft 18, and the connector 4 is fixed to the other end of the transverse connecting member 2. The elastic member 5 is preferably located in the hinge between the first telescopic power unit 3 and the transverse connecting member 2, so as not to hinge with the first telescopic power unit 3, and can better maintain the vertical state, so as to better cooperate with the rolling cylinder 8 to tilt with the terrain, etc.

[0047] As Figure 2 , the first telescopic power unit 3 can be a hydraulic cylinder, which has a first telescopic shaft 301. The first telescopic shaft 301 can be horizontally and longitudinally arranged, and is substantially parallel to the forward direction of the vehicle body.

[0048] The first longitudinal connecting member 6 can be a horizontally and longitudinally arranged connecting rod. One end of the first longitudinal connecting member 6 is fixedly connected to the first telescopic shaft 301, and the other end is hinged to the first transverse arm 9.

[0049] The second longitudinal connecting member 7 can be a horizontally and longitudinally arranged connecting rod. One end of the second longitudinal connecting member 7 is fixedly connected to the connector 4, and the other end is hinged to the second transverse arm 10.

[0050] The first transverse arm 9 and the second transverse arm 10 are rotatably connected to the two ends of the rolling cylinder 8. The first transverse arm 9 and the second transverse arm 10 can both be horizontally and transversely arranged, and are approximately perpendicular to the forward direction of the main body 1.

[0051] The rolling cylinder 8 can be a hollow cylindrical steel cylinder.

[0052] The first longitudinal connecting member 6 and the second longitudinal connecting member 7 are not absolutely horizontally and longitudinally arranged, and the first transverse arm 9 and the second transverse arm 10 are not absolutely horizontally and transversely arranged, and due to the hinged relationship between these components, there can be a certain inclination deformation. For example, the transverse connecting member 2, the first longitudinal connecting member 6, the second longitudinal connecting member 7, the first transverse arm 9, the rolling cylinder 8 and the second transverse arm 10 are connected to form a quadrilateral.

[0053] The asphalt pavement ramming device forms a three-point hinged structure with the rolling cylinder 8, which is the hinge between the first telescopic power unit 3 or the connector 4 and the transverse connecting member 2, the hinge between the first longitudinal connecting member 6 and the first transverse arm 9, and the hinge between the second longitudinal connecting member 7 and the second transverse arm 10. Under the drive of the first telescopic power unit 3, the first longitudinal connecting member 6 moves forward or backward, driving the first transverse arm 9 to move forward or backward. If the connector 4 does not output power, the rolling cylinder 8 is driven by the first transverse arm 9 to rotate in the horizontal plane, so that the rolling cylinder 8 of the pavement ramming device can perform a turning motion at the turning place of the pavement.

[0054] The transverse connecting member 2 passes through the vertical hole 101, two elastic members 5 hoist the transverse connecting member 2, two ends of the transverse connecting member 2 are connected with the first telescopic power device 3 and the connector 4, so that the first telescopic power device 3 and the connector 4 have the moving space up and down, and because the first telescopic power device 3 and the connector 4 are connected with two ends of the rolling cylinder 8 through the first longitudinal connecting member 6 and the second longitudinal connecting member 7 respectively, so that two ends of the rolling cylinder 8 have the moving space high and low, so that the road surface ramming equipment can present the terrain of low inside and high outside when turning at the asphalt pavement, the rolling cylinder 8 in front can present the high-low side inclination relative to the main body 1 behind, the rolling cylinder 8 can not be in the same plane with the main body 1, so that the rolling cylinder 8 can well fit the road surface, present the posture of low inside and high outside with the asphalt pavement, and the ramming effect is good.

[0055] As Figure 2 In a preferred embodiment, the connector 4 is a second telescopic power device. The second telescopic power device has a second telescopic shaft 401 arranged horizontally and longitudinally, and the second telescopic shaft 401 is fixedly connected with the second longitudinal connecting member 7. The second telescopic power device can be the same as the first telescopic power device 3, and can be a hydraulic cylinder and the like. The first longitudinal connecting member 6 and the second longitudinal connecting member 7 can be horizontal and longitudinal rod members. The first telescopic shaft 301 of the first telescopic power device 3 can be fixed to the first longitudinal connecting member 6 and can be in the same straight line. The second telescopic shaft 401 of the second telescopic power device can be fixed to the second longitudinal connecting member 7 and can be in the same straight line. The second telescopic power device can also drive the second longitudinal connecting member 7 to move forward or backward, and cooperates with the first telescopic power device 3 to drive the rolling cylinder 8 to turn, and the driving efficiency is higher. For example, the first telescopic power device 3 and the second telescopic power device can be controlled to move by stretching and shrinking at the same time, so that the turning control of the rolling cylinder 8 is more rapid.

[0056] In an optional embodiment, the connector 4 can be a connection block in the shape of a cuboid or the like, and the front side thereof is connected with the second longitudinal connecting member 7, and the side thereof is connected with the transverse connecting member 2. Through the driving of the first telescopic power device 3, the arms where the first longitudinal connecting member 6 and the second longitudinal connecting member 7 are located are not equal in length, and the turning control of the rolling cylinder 8 can also be realized.

[0057] In a preferred embodiment, the width of the vertical hole 101 is equal to the width of the transverse connecting member 2, so that the transverse connecting member 2 is fitted into the vertical hole 101 and moves vertically along the vertical hole 101, and the front and back sides of the transverse connecting member 2 abut against the vertical hole 101. When the asphalt pavement ramming device moves forward or backward, the main body 1 and the rolling cylinder 8 can move synchronously by the abutment structure. The transverse connecting member 2 moves vertically along the vertical hole 101 and cannot move horizontally along the vertical hole 101, so that the rolling cylinder 8 does not move forward and backward through the vertical hole 101, but moves forward and backward synchronously or asynchronously at both ends through the extension and contraction drive of the first extension and contraction power device 3 or the connector 4, so that the rolling cylinder 8 moves linearly forward or turns, i.e., the first extension and contraction power device 3 and the connector 4 can accurately control the turning of the rolling cylinder 8.

[0058] As Figure 4 The asphalt pavement ramming device can further comprise a first rotary driver 11 and a rotary receiving member 12. The first rotary driver 11 comprises a first stator 111 and a first rotary shaft 112. The first rotary driver 11 can be a motor or the like, and the first stator 111 can be a housing or the like component. The first rotary shaft 112 can rotate in place in the first stator 111. The first stator 111 is fixed to the first cross arm 9, and the first rotary shaft 112 is fixed to one end of the rolling cylinder 8, i.e., the first cross arm 9 is indirectly connected to one end of the rolling cylinder 8 through the first rotary driver 11. The rotary receiving member 12 is a component that can receive the rotary motion of the rolling cylinder 8 and appears relatively stationary to the outside. For example, the rotary receiving member 12 comprises a second stator 121 and a second rotary shaft 122. The second rotary shaft 122 can rotate in place in the second stator 121. The second stator 121 is fixed to the second cross arm 10. The second rotary shaft 122 is connected to the other end of the rolling cylinder 8, i.e., the second cross arm 10 is indirectly connected to the other end of the rolling cylinder 8 through the rotary receiving member 12.

[0059] The first rotary driver 11 outputs power, which, in cooperation with the rotary receiving member 12, can drive the rolling cylinder 8 to rotate, thereby improving the power of the device when moving uphill or downhill.

[0060] Since the first rotary driver 11 is installed on the first cross arm 9, the first cross arm 9 can perform hinged motion relative to the first longitudinal connecting member 6, and the rotary receiving member 12 is installed on the second cross arm 10, so the second cross arm 10 can perform hinged motion relative to the second longitudinal connecting member 7. Therefore, the rolling cylinder 8 can be driven by the first cross arm 9 and the second cross arm 10 to perform turning motion.

[0061] The rotating receiving member 12 can be a second rotating driver. The second rotating driver can have the same structure as the first rotating driver 11, and can be an electric motor. The second rotating driver and the first rotating driver 11 can be arranged to rotate synchronously, and to drive the rolling cylinder 8 to rotate, thereby improving the operation efficiency.

[0062] The rotating receiving member 12 can also be a bearing member, which includes the second rotating shaft 122 as described above. The first rotating driver 11 drives the rolling cylinder 8 to rotate, and the bearing member receives the rotating motion at the other end. The rolling cylinder 8 is driven by the first rotating driver 11 to move forward or backward.

[0063] As shown in FIG. 4 and Figure 5 In an optional embodiment, the asphalt pavement tamping device further includes a first inner shaft 13 and a second inner shaft 14. The first rotating shaft 112 is fixedly connected to the first inner shaft 13. The first inner shaft 13 is fixed to the axial center of one end of the rolling cylinder 8. The axial center of the first rotating shaft 112 is parallel to the axial center of the first inner shaft 13, i.e., the first rotating shaft 112 and the first inner shaft 13 are not coaxial. The second rotating shaft 122 is fixedly connected to the second inner shaft 14. The second inner shaft 14 is fixedly connected to the axial center of the other end of the rolling cylinder 8. That is, the first inner shaft 13 and the second inner shaft 14 are both fixed to the axial center of the rolling cylinder 8, so that the first inner shaft 13 and the second inner shaft 14 are coaxial. The axial center of the second rotating shaft 122 coincides with the axial center of the first rotating shaft 112. The first rotating driver 11 can drive the first inner shaft 13 to perform a circular motion around the first rotating shaft 112, i.e., to perform an eccentric rotation. Similarly, the second inner shaft 14 and the first inner shaft 13 perform an eccentric rotation synchronously. By setting a small eccentric amplitude and a large rotating speed, the first inner shaft 13 and the second inner shaft 14 can quickly perform a small-amplitude circular motion, i.e., to generate a vibration effect. Since the first inner shaft 13 and the second inner shaft 14 are both connected to the rolling cylinder 8, the rolling cylinder 8 generates a vibration motion effect.

[0064] In order to achieve the above-mentioned arrangement that the first inner shaft 13 is fixed to the axial center of one end of the rolling cylinder 8, and the second inner shaft 14 is fixedly connected to the axial center of the other end of the rolling cylinder 8, a disc 15 with a certain thickness can be fixedly arranged in the rolling cylinder 8. The disc 15 is tangentially welded to the inner wall of the rolling cylinder 8. The first inner shaft 13 is fixedly arranged at the center of the disc 15 from one side, and the second inner shaft 14 is fixedly arranged at the center of the disc 15 from the other side.

[0065] In order to make the eccentric first rotating shaft 112 and the first inner shaft 13 more firmly fixed, and make the eccentric second rotating shaft 122 and the second inner shaft 14 more firmly fixed, the asphalt pavement ramming equipment can further be provided with a first cylindrical block 16 and a second cylindrical block 17. The first rotating shaft 112 and the first inner shaft 13 are respectively fixed in the two end faces of the first cylindrical block 16, the contact area is large, and the structure is relatively firm. The second rotating shaft 122 and the second inner shaft 14 are respectively fixed in the two end faces of the second cylindrical block 17, the contact area is large, and the eccentric connection structure is relatively firm.

[0066] In order to further improve the stability of the eccentric rotating structure, the first horizontal arm 9, the first rotating shaft 112 and the first cylindrical block 16 are coaxial, and the second horizontal arm 10, the second rotating shaft 122 and the second cylindrical block 17 are coaxial. When the first rotating shaft 112 rotates, the first cylindrical block 16 only performs a circumferential rotation motion, the motion amplitude is small, the motion is stable, and the operation stability of the connection structure is improved. The first horizontal arm 9 and the first rotating shaft 112 are coaxial, the influence of centrifugal force on the first horizontal arm 9 is reduced, and the connection structure is relatively stable. Similarly, the connection structure of the second horizontal arm 10, the rotating bearing 12 and the second cylindrical block 17 is stable, and the operation stability is high.

[0067] In an improved embodiment, the first inner shaft 13 and the second inner shaft 14 are fixedly connected and integrally formed. After the first inner shaft 13 and the second inner shaft 14 are connected and integrally formed, the two ends of the formed body are fixed in the inside of the rolling cylinder 8, the structure is more firm, and the rotation is more synchronous and stable.

[0068] Please refer to Figure 3 In an optional embodiment, the main body 1 is a vehicle body. The vehicle body includes a vehicle head 102, an outward expansion plate 103 and a cab 104. The outward expansion plate 103 is fixed to the bottom of the cab 104. The outward expansion plate 103 is located above the vehicle head 102. The vehicle head 102 is provided with a vertical hole 101. The upper ends of the two elastic members 5 are fixed to the bottom surface of the outward expansion plate 103 and are suspended on both sides of the vehicle head 102. The vehicle body can drive the rolling cylinder 8 to move forward or backward. The elastic member 5 is suspended on the bottom of the cab 104, and the vibration of the rolling cylinder 8 is absorbed by the elastic member 5, so that the influence on the cab 104 is small, and the driving comfort is improved.
