DETAILED DESCRIPTION

[0035] Embodiment 1, the present invention provides as Figures 1 to 8 The magnetic suction auxiliary positioning ram head installation device shown comprises a ram head body 1 and a shock-absorbing pad body 2 installed on the top of the ram head body 1. A positioning frame 30 is arranged above the ram head body 1, and one end of the shock-absorbing pad body 2 away from the ram head body 1 is connected to the side of the positioning frame 30. The positioning frame 30 is provided with structures such as a vibration box and a battery box. The installation connection between the ram head body 1 and the positioning frame 30 is completed by the shock-absorbing pad body 2. The shock-absorbing pad body 2 is made of rubber material, which can absorb the periodic vibration force generated by the ram head body 1 during the operation of the flat plate ram, and reduce the impact on the vibration box, battery box and other structures.

[0036] Taking into account the characteristics of the rubber material itself, when used outdoors, the performance of the shock-absorbing pad 2 will change due to the influence of the ambient temperature. For example, when used under low temperature conditions, the shock-absorbing pad 2 is prone to hardening and loses its original shock-absorbing effect; when used under high temperature conditions, the shock-absorbing pad 2 is prone to softening, resulting in its inability to continue to effectively play a shock-absorbing role. In order to ensure that the shock-absorbing pad 2 has a stable shock-absorbing effect, an airbag bag 3 for adjusting the elastic performance is provided inside the shock-absorbing pad 2.

[0037] Specifically, when used under high temperature conditions, the airbag bag 3 expands and becomes larger, providing rigid support for the shock-absorbing pad body 2, so that the shock-absorbing pad body 2 will not deform at will; when used under low temperature conditions, the airbag bag 3 shrinks and becomes smaller, and the interior of the shock-absorbing pad body 2 has a certain deformation space, and the shock-absorbing pad body 2 is more likely to deform; by providing the airbag bag 3 and adaptively adjusting the airbag bag 3 according to the temperature conditions of use, the shock-absorbing pad body 2 maintains stable shock-absorbing performance, thereby improving the efficiency of installation and use of the ramming head body 1.

[0038] Considering that the shock-absorbing pad body 2 is easily affected by the external environment, such as water vapor, acid, alkali, salt and other chemical factors, which will cause the shock-absorbing pad body 2 to age, thereby generating cracks, shortening the service life, and affecting the installation and connection effect between the ram head body 1 and the positioning frame 30, in order to ensure the stability of the flat ram, the outside of the shock-absorbing pad body 2 is wrapped with an airbag cover 6, the airbag cover 6 protects the shock-absorbing pad body 2 and extends the service life of the shock-absorbing pad body 2; and when the airbag cover 6 ages, etc., it only needs to be replaced to reduce the cost of equipment use.

[0039] Considering that dust and other impurities are easily attached to the outside of the airbag cover 6 during the use of the plate compactor, in order to facilitate subsequent cleaning by personnel, first magnets 4 are fixedly embedded at both upper and lower ends of the interior of the shock-absorbing pad 2, and third magnets 7 are arranged above and below the shock-absorbing pad 2. The third magnets 7 are fixedly connected to the inner wall of the airbag cover 6 (refer to Figure 4 ), the third magnet 7 and the corresponding first magnet 4 repel each other to form a raised portion 8.

[0040] When used specifically, the installation distribution of the shock-absorbing pad body 2 is as follows: Figure 1 At this time, the two raised portions 8 are respectively distributed at the upper and lower ends of the airbag cover 6 .

[0041] Since the movement of the ram head body 1 is mostly lifting and vibration, when the ram head body 1 is rapidly lifted and vibrated, the raised portion 8 is easily squeezed and deformed. When the raised portion 8 is squeezed, the gas at the raised portion 8 will flow into other positions inside the airbag cover 6. During frequent deformations, a shaking effect is formed on the outside of the airbag cover 6, and the up and down movement of the airbag cover 6 itself is coordinated to shake off adhered impurities, avoid long-term accumulation and solidification, prevent affecting the elastic deformation capacity of the shock-absorbing pad body 2, and facilitate subsequent cleaning by the operator.

[0042] By providing structures such as the airbag cover 6 and the raised portion 8, the airbag cover 6 protects the shock-absorbing pad body 2 and extends the service life of the shock-absorbing pad body 2; and when the airbag cover 6 becomes aged, it is only necessary to replace the airbag cover 6, thereby reducing the cost of equipment use. At the same time, a shaking effect is formed on the outside of the airbag cover 6 to shake off adhered impurities, avoid long-term accumulation and solidification, prevent affecting the elastic deformation ability of the shock-absorbing pad body 2, and facilitate subsequent cleaning by the operator.

[0043] In order to achieve the installation and fixation of the airbag cover 6, both ends of the airbag cover 6 are fixedly connected with rings 29, the rings 29 are sleeved on the outside of the shock-absorbing pad body 2, and the ends of the two rings 29 that are far away from each other are threadedly connected with threaded sleeves 9.

[0044] When in use, the airbag cover 6 is sleeved on the outside of the shock-absorbing pad body 2 , and then the two threaded sleeves 9 are respectively connected to the circular rings 29 at both ends to complete the fixing of the airbag cover 6 .

[0045] In addition, since it is necessary to set up the first magnet 4, airbag bag 3 and other structures, the shock-absorbing pad body 2 can be made of two parts glued and spliced ​​together, and the airbag sleeve 6, threaded sleeve 9 and ring 29 are set and wrapped around the outside of the shock-absorbing pad body 2, which can improve the use strength of the shock-absorbing pad body 2.

[0046] The upper and lower ends of the airbag 3 are fixedly connected with second magnets 5 , and the second magnets 5 and the corresponding first magnets 4 are repelled from each other.

[0047] Specifically, by providing structures such as the first magnet 4 and the second magnet 5, when the airbag bag 3 expands and becomes larger, the distance between the second magnet 5 and the corresponding first magnet 4 is reduced, and the repulsive force becomes stronger, so that the shock-absorbing pad body 2 is not easily deformed at the position between the airbag bag 3 and the airbag cover 6; when the airbag bag 3 shrinks and becomes smaller, the distance between the second magnet 5 and the corresponding first magnet 4 is expanded, and the repulsive force becomes weaker, so that the shock-absorbing pad body 2 is easily deformed at the position between the airbag bag 3 and the airbag cover 6, thereby ensuring the uniformity of the elastic deformation of the shock-absorbing pad body 2 and further improving the shock-absorbing performance of the shock-absorbing pad body 2.

[0048] Inside the airbag 3, the magnetic properties of the two second magnets 5 on the sides close to each other can be opposite, which can be adjusted according to specific usage conditions; and a magnetic isolation plate can be provided between the two second magnets 5 to reduce the mutual influence.

[0049] Taking into account that the shock-absorbing pad body 2 vibrates with the plate rammer, in order to prevent the airbag bag 3 from stacking after long-term use, the second magnet 5 has a certain length to support the airbag bag 3, avoid stacking of the airbag bag 3, and improve the efficiency of inflation.

[0050] One end of the shock-absorbing pad body 2 is fixedly connected to the first circular plate 12, and a circular groove is provided inside the first circular plate 12. The inside of the circular groove is fixedly connected to the air cylinder 13, and the air cylinder 13 extends to the outside of the shock-absorbing pad body 2. One end of the air cylinder 13 located outside the shock-absorbing pad body 2 is threadedly connected to the first nut 25. One end of the shock-absorbing pad body 2 away from the first circular plate 12 is fixedly connected to the second circular plate 26, and the second circular plate 26 is fixedly connected to the side facing away from the first circular plate 12. The connecting rod 27 extends to the outside of the shock-absorbing pad body 2, and the second nut 28 is threadedly connected to the connecting rod 27.

[0051] One of the threaded sleeves 9 surrounds the outside of the cylinder 13, and the other threaded sleeve 9 surrounds the outside of the connecting rod 27 (refer to Figure 4 ).

[0052] In actual use, one end of the shock-absorbing pad 2 is installed by cooperating with the first nut 25 and the air cylinder 13; the other end of the shock-absorbing pad 2 is installed by cooperating with the second nut 28 and the connecting rod 27; and one end of the shock-absorbing pad 2 is installed on the ram head body 1, and the other end is installed on the positioning frame 30.

[0053] Considering that the shock-absorbing pad body 2 will vibrate frequently during use, the gas inside the airbag bag 3 is likely to flow back to the inside of the air cylinder 13 due to vibration, squeezing, etc., thereby affecting the expansion degree of the airbag bag 3. In order to improve the stability of use, the air cylinder 13 is connected to the airbag bag 3, and the inside of the air cylinder 13 is rotatably connected with a threaded cylinder 14. The threaded cylinder 14 is located at the end of the air cylinder 13 away from the airbag bag 3, and the end of the air cylinder 13 close to the airbag bag 3 is slidably provided with a threaded rod 15, and the threaded rod 15 cooperates with the threaded cylinder 14. A slide groove 16 is provided on the inner wall of the air cylinder 13, and a slider 17 is slidably provided inside the slide groove 16. The slider 17 is fixedly connected to the threaded rod 15. The slide groove 16 and the slider 17 are provided so that the threaded rod 15 does not rotate.

[0054] A support plate 21 is disposed outside the shock-absorbing pad body 2 . The support plate 21 is L-shaped. A slot 19 is formed at one end of the threaded tube 14 away from the threaded rod 15 . A block 20 is engaged inside the slot 19 . The block 20 is fixedly connected to the support plate 21 .

[0055] A square box 22 is slidably arranged on the support plate 21, and two sixth magnets 24 are arranged inside the square box 22, one of which is fixedly connected to the support plate 21, and the other is fixedly connected to the inner wall of the square box 22. The two sixth magnets 24 are relatively distributed, and the two sixth magnets 24 attract and cooperate with each other. A U-shaped clamping plate 23 is fixedly connected to one end of the square box 22 away from the support plate 21, and the support plate 21, the square box 22 and the U-shaped clamping plate 23 are arranged in a U shape. A limiting groove 18 is provided on the first nut 25 to be clamped with the U-shaped clamping plate 23, and the inner wall of the limiting groove 18 is a polygonal structure. When the U-shaped clamping plate 23 is clamped into the limiting groove 18, there will be no relative rotation between the U-shaped clamping plate 23 and the first nut 25.

[0056] Specifically, after the threaded cylinder 14 finishes rotating, the U-shaped clamping plate 23 is aligned with the limiting groove 18 up and down, and the support plate 21 is pulled in the direction away from the shock-absorbing pad body 2, and then the U-shaped clamping plate 23 is inserted into the limiting groove 18, and the position of the clamping block 20 corresponds to the position of the clamping groove 19. The magnetic attraction force between the two sixth magnets 24 causes the support plate 21 to drive the clamping block 20 to be inserted into the interior of the clamping groove 19.

[0057] When the threaded rod 15 moves toward the threaded tube 14 inside the air cylinder 13, the rotation direction of the threaded tube 14 is the same as the rotation direction of the first nut 25 for installation and tightening. When the gas inside the airbag bag 3 flows back to the inside of the air cylinder 13 due to extrusion, it will squeeze the threaded rod 15 to move toward the threaded tube 14 inside the air cylinder 13. The threaded rod 15 drives the threaded tube 14 to rotate, but the first nut 25 abuts against the ram head body 1 and other structures and cannot rotate. Therefore, the threaded tube 14 is positioned with the cooperation of the magnetic attraction force, so that the airbag bag 3 maintains a stable expansion degree, thereby improving the stability of the shock-absorbing pad 2.

[0058] By providing structures such as the U-shaped clamping plate 23 and the sixth magnet 24 , the threaded tube 14 is positioned with the cooperation of the magnetic attraction force, so that the airbag bag 3 maintains a stable expansion degree, thereby improving the stability of the shock-absorbing pad body 2 in use.

[0059] Embodiment 2, the present invention provides as Fig. 9 A magnetically assisted positioning ram head installation device is shown, in which a fourth magnet 10 is fixedly connected to one end of a threaded rod 15 close to the airbag bag 3, and a fifth magnet 11 is fixedly connected to the inner wall of the airbag bag 3. The fourth magnet 10 and the fifth magnet 11 are relatively distributed, and the fourth magnet 10 and the fifth magnet 11 repel each other.

[0060] Due to the repulsive cooperation between the fourth magnet 10 and the fifth magnet 11, the airbag 3 is always kept in the expanded state, avoiding the occurrence of stacking and the like, thereby improving the efficiency of inflation. This solution is suitable for some areas where the temperature changes are not much different throughout the year. It is only necessary to adjust the elastic deformation capacity of the shock-absorbing pad 2 through the expansion and contraction of the airbag 3, without using the repulsive force between the second magnet 5 and the first magnet 4, thereby reducing the cost of equipment use.

[0061] Working principle: To prevent the shock-absorbing pad body 2 from being affected by the external environment during use, such as the effects of chemical factors such as water vapor, acid, alkali, salt, etc., which will cause the shock-absorbing pad body 2 to age and thus produce cracks, the airbag cover 6 is wrapped around the outside of the shock-absorbing pad body 2, and through the cooperation of structures such as the circular ring 29 and the threaded sleeve 9, the shock-absorbing pad body 2 is protected to extend the service life of the shock-absorbing pad body 2; and when the airbag cover 6 is aged, etc., it only needs to be replaced to reduce the cost of equipment use.

[0062] During installation, the two protrusions 8 are respectively distributed at the upper and lower ends of the airbag cover 6. Since the movement of the ram head body 1 is mostly lifting and vibration, the protrusions 8 are easily squeezed and deformed. When the protrusions 8 are squeezed, the gas at the protrusions 8 will flow into other positions inside the airbag cover 6. During frequent deformation, the outside of the airbag cover 6 forms a shaking effect, and cooperates with the up and down movement of the airbag cover 6 itself to shake off the adhered impurities, avoid long-term accumulation and solidification, prevent affecting the elastic deformation ability of the shock-absorbing pad body 2, and facilitate subsequent cleaning by the operator.

[0063] When used under low temperature conditions, the shock-absorbing pad body 2 is prone to hardening and loses its original shock-absorbing effect. At this time, the threaded cylinder 14 is rotated, and under the limiting action of the slide groove 16 and the slider 17, the threaded rod 15 moves inside the air cylinder 13 in a direction away from the airbag bag 3, and the gas inside the airbag bag 3 is sucked into the interior of the air cylinder 13, and the airbag bag 3 shrinks and becomes smaller, and there is a certain deformation space inside the shock-absorbing pad body 2; at the same time, the distance between the second magnet 5 and the corresponding first magnet 4 is enlarged, the repulsive force is weakened, and the shock-absorbing pad body 2 is more likely to deform, so that it can restore a better shock-absorbing effect.

[0064] When used under high temperature conditions, the shock-absorbing pad body 2 is prone to softening, resulting in its inability to continue to effectively play a shock-absorbing role. At this time, the threaded cylinder 14 is rotated in the opposite direction, and under the limiting action of the slide groove 16 and the slider 17, the threaded rod 15 moves toward the airbag bag 3 inside the air cylinder 13. The gas inside the air cylinder 13 enters the airbag bag 3, and the airbag bag 3 expands and becomes larger, providing rigid support for the shock-absorbing pad body 2; at the same time, the distance between the second magnet 5 and the corresponding first magnet 4 is reduced, the repulsive force becomes stronger, and the shock-absorbing pad body 2 is not easy to deform, so that it can restore a better shock-absorbing effect.

[0065] After the threaded cylinder 14 finishes rotating, the U-shaped clamping plate 23 is aligned with the limiting groove 18 up and down, and the support plate 21 is pulled in the direction away from the shock-absorbing pad body 2, and then the U-shaped clamping plate 23 is inserted into the limiting groove 18, and the positions of the clamping block 20 and the clamping groove 19 correspond. The magnetic attraction force between the two sixth magnets 24 causes the support plate 21 to drive the clamping block 20 to be inserted into the interior of the clamping groove 19. When the threaded rod 15 moves toward the threaded tube 14 inside the air cylinder 13, the rotation direction of the threaded tube 14 is the same as the rotation direction of the first nut 25 for installation and tightening. When the gas inside the airbag bag 3 flows back to the inside of the air cylinder 13 due to extrusion, it will squeeze the threaded rod 15 to move toward the threaded tube 14 inside the air cylinder 13. The threaded rod 15 drives the threaded tube 14 to rotate, but the first nut 25 abuts against the ram head body 1 and other structures and cannot rotate. Therefore, the threaded tube 14 is positioned with the cooperation of the magnetic attraction force, so that the airbag bag 3 maintains a stable expansion degree, thereby improving the stability of the shock-absorbing pad 2.
