Asphalt Road Base Damage Repair Device

Abstract

The present invention relates to the field of repairing damaged bases of asphalt roads, and discloses a device for repairing damaged bases of asphalt roads, including a mobile base. A bitumen storage tank is fixedly arranged on the top of the mobile base, and a driving motor is fixedly arranged on the top of the bitumen storage tank. Compared with the prior art, in this application, the driving motor drives the reciprocating screw rod to rotate through the stirring shaft and the transmission components, so that the reciprocating nut sleeve drives the pushing plate to move through the moving plate. The pushing plate drives the rotating gear to rotate by pushing the driving rack, and drives the rotating rod to rotate, and drives the perfusion pipe to turn over through the rotating rod. And during this process, the turning angle of the perfusion pipe does not exceed thirty degrees. Tilting the discharge port of the perfusion pipe at a certain angle towards the direction of the wind can make the bitumen more accurately enter the crack under the push of the wind, avoiding excessive bitumen being blown to the area outside the crack, resulting in waste of bitumen, thereby improving the perfusion accuracy and making the perfusion bitumen more uniform.

Description

Technical Field

[0001] The present invention relates to the field of repairing damaged bases of asphalt roads, and specifically to a device for repairing damaged bases of asphalt roads. Background Art

[0002] An asphalt road is mainly constructed by mixing asphalt materials and mineral materials in a certain proportion, through a series of steps such as heating, stirring, paving, and compaction. Since the surface of the asphalt road is relatively flat, vehicles driving on the asphalt road surface will not experience large bumps, making the vehicle driving smoothly. When the vehicle is driving at high speed, the asphalt road surface with high flatness will improve the driving safety and comfort. Due to the characteristics of its own materials, the asphalt road surface has certain elasticity and pores, and through these elasticity and pores, the vibration and sound generated by the contact between the tire and the road surface can be buffered and absorbed, thereby reducing the noise during vehicle driving.

[0003] However, during the use of the asphalt road surface, when heavy trucks drive on the asphalt road surface for a long time, the axle weight is too large, which will cause the road surface and base of the asphalt road to bear huge vertical pressures. The excessive pressure will cause fatigue damage to the internal structure of the base, resulting in cracks in the road surface and base of the asphalt road. And with the repeated action of vehicle loads, the cracks will gradually expand and extend. Moreover, impacts will be generated during the acceleration, deceleration, and braking of the vehicle, and the generated impacts will cause vibrations of the base. The stress state inside the base material will change due to the impact of the vibration. When the stress exceeds the tensile strength of the material itself, cracks will be generated. After the cracks are generated, the cracks need to be repaired to prevent the cracks from continuing to expand. When repairing the base of the asphalt road, a repair device is usually used to pour melted asphalt into the cracks and compact the poured asphalt.

[0004] During the use of the repair device, the melted asphalt is usually added into a heatable storage tank, and then the melted asphalt is transported to the perfusion pipe through a delivery pump. The melted asphalt is transported to the cracks through the perfusion pipe, and then the poured asphalt is compressed by a compaction mechanism, so that the asphalt fully enters the cracks.

[0005] However, during the use of the repair device, it will be affected by external factors. For example, strong self-heating wind will appear during the pouring process. The strong self-heating wind will disrupt the normal spreading and pouring of the repair material. Mainly, strong wind will blow away the freshly spread asphalt, resulting in the asphalt being unable to be evenly distributed on the damaged base surface, which will lead to waste of asphalt and a decrease in the quality of pouring. Secondly, strong natural wind will accelerate the heat dissipation of asphalt, causing the asphalt to solidify prematurely. This situation is particularly obvious in low temperature environments. The solidified asphalt is difficult to be compacted by compaction equipment, resulting in insufficient compaction strength and durability of the repaired road surface, and dents and cracks are likely to occur during subsequent use. Based on the above problems, the present application proposes a device for repairing damaged asphalt road base surfaces. Summary of the invention

[0006] In view of the shortcomings of the prior art, the present invention provides a device for repairing damaged asphalt road base surface, which has the advantages of ensuring the uniformity of asphalt filling, ensuring the quality of asphalt road repair, and avoiding the occurrence of dents and cracks on the repaired asphalt road base surface in a short time.

The moving plate 10 drives the fixed seat 7 and the pushing plate 24 to move, so that the rotating shaft 14 drives the compaction roller 15 to move towards the pouring pipe 20. At the same time, the driving tooth plate 21 pushes the rotating gear 19 to drive the rotating rod 18 to rotate, so that the pouring pipe 20 is flipped to a suitable angle, which is convenient for adjusting the pouring angle according to the wind force, and is convenient for adjusting the compaction roller 15 to compress the tar at different times after pouring, which can ensure the uniformity of the poured tar.Moreover, it can avoid the situation where the asphalt solidifies when the compaction roller 15 compacts the asphalt.

[0037] The asphalt conveying component 16 is arranged on the top of the moving base 1 and is used to convey the asphalt in the asphalt storage tank 2, so as to facilitate the conveyance of the asphalt to the perfusion pipe 20, thereby facilitating the perfusion pipe 20 to perfuse the cracks in the asphalt road base.

[0038] As a preferred implementation manner in this embodiment, referring to Figure 6 and Figure 7 As shown, the transmission component 6 includes a worm 61 fixedly installed at the bottom end of the stirring shaft 4.

The two bevel gears 610 are respectively fixedly installed at the front end of the connecting shaft 65 and the right end of the reciprocating screw 8. The driving motor 3 drives the stirring shaft 4 to drive the stirring paddle 5 and the worm 61 to rotate forward or backward, so that the stirring paddle 5 stirs the added asphalt. When rotating forward, the worm 61 drives the meshed worm gear 62 to drive the rotating shaft 63 to rotate, so that the ratchet sleeve one 66 pushes the ratchet sleeve two 67 to move forward and compresses the connecting spring 68. When rotating backward, the worm 61 drives the meshed worm gear 62 to drive the rotating shaft 63 to rotate, so that the ratchet sleeve one 66 drives the ratchet sleeve two 67 to rotate. The ratchet sleeve two 67 drives the connecting shaft 65 to rotate through the limiting block and the limiting groove, and the connecting shaft 65 drives the reciprocating screw 8 to rotate through the bearing inside the fixed seat 7 through the bevel gear 610, thereby facilitating the control of the rotation and stop of the reciprocating screw 8, so that the repair device can perfuse the cracks in the asphalt road base under both windless and windy conditions.

[0039] As a preferred implementation manner in this embodiment, referring to Figure 8 and Figure 9As shown in the figure, the asphalt conveying component 16 includes a support frame 161 fixedly installed on the top of the moving base 1. A conveying pump 162 is fixedly arranged on the top of the support frame 161. The inlet end of the conveying pump 162 is fixedly provided with a feed pipe 163. The inlet end of the feed pipe 163 penetrates through the asphalt storage tank 2 and extends into the interior of the asphalt storage tank 2. The outlet end of the conveying pump 162 is fixedly provided with a discharge pipe 164. A fixing hoop 165 is fixedly arranged on the surface of the discharge pipe 164. The bottom of the fixing hoop 165 is fixedly provided with a connecting frame 166. The connecting frame 166 is fixedly installed on the top of the moving base 1. A rotary joint 167 is arranged at the outlet end of the connecting frame 166. The rotary joint 167 includes an installation pipe 1671 fixedly installed inside the discharge pipe 164. A sealing bearing 1672 is installed on the surface of the installation pipe 1671. The inner ring of the sealing bearing 1672 is connected to the installation pipe 1671. The outer ring of the sealing bearing 1672 is fixedly provided with a rotary sleeve 1673. A rotary pipe 1674 is fixedly arranged on the front side of the rotary sleeve 1673. The perfusion pipe 20 is fixedly installed at the front end of the rotary pipe 1674. The conveying pump 162 pumps out the melted asphalt in the asphalt storage tank 2 through the feed pipe 163, conveys it into the interior of the discharge pipe 164, and then enters the interior of the perfusion pipe 20 through the rotary joint 167. During the rotation of the perfusion pipe 20, the perfusion pipe 20 drives the rotary pipe 1674 to rotate, and the rotary pipe 1674 drives the rotary sleeve 1673 to rotate through the sealing bearing 1672, so as to facilitate the conveying of asphalt into the interior of the perfusion pipe 20. At the same time, after the perfusion pipe 20 rotates, the normal conveying of asphalt can be ensured.

[0040] As a preferred implementation method in this embodiment, refer to Figure 10 and Figure 11 As shown in the figure, the angle limiting component 22 includes an installation sleeve 221 fixedly installed on the surface of the rotating rod 18. A limiting spring 222 is fixedly arranged inside the installation sleeve 221. A limiting convex block 223 is fixedly arranged at the end of the limiting spring 222. The limiting convex block 223 is slidably arranged inside the installation sleeve 221. A triangular block 224 is lapped on the surface of the limiting convex block 223. The number of triangular blocks 224 is several. Several triangular blocks 224 are all fixedly installed inside the fixing plate 17. The perfusion pipe 20 drives the installation sleeve 221, the limiting spring 222 and the limiting convex block 223 to move, so that the triangular block 224 pushes the limiting convex block 223 to contract into the installation sleeve 221 and compresses the limiting spring 222. When the rotating rod 18 drives the perfusion pipe 20 to flip to an appropriate angle, the limiting convex block 223 is pushed by the resilience of the limiting spring 222 to reinsert between the triangular blocks 224 to limit the position of the rotating rod 18, and thus the flipping angle of the perfusion pipe 20 can be limited by the rotating rod 18, avoiding the change of the perfusion angle of the perfusion pipe 20 during the perfusion process, resulting in a smaller flipping angle or reset, and thus avoiding the uneven asphalt perfusion caused by the angle change of the perfusion pipe 20.

[0041] Working principle of the present invention: During use, melted asphalt is added into the interior of the asphalt storage tank 2 through the feeding pipe, and the added asphalt is heated by the heating plate 25. Meanwhile, the driving motor 3 drives the output end to drive the stirring shaft 4 to rotate, and the stirring shaft 4 drives the stirring paddle 5 and the worm 61 to rotate. The added asphalt is stirred by the stirring paddle 5. Meanwhile, the worm 61 drives the engaged worm wheel 62 to rotate, and the worm wheel 62 drives the rotating shaft 63 to rotate. The ratchet sleeve one 66 moves along the inclined plane direction of the ratchet sleeve two 67 through the rotating shaft 63, so that the ratchet sleeve one 66 pushes the ratchet sleeve two 67 to move forward, and the ratchet sleeve two 67 compresses the connecting spring 68. At this time, the transfer pump 162 pumps out the melted asphalt in the asphalt storage tank 2 through the feed pipe 163, and transports it into the interior of the discharge pipe 164, and then enters the perfusion pipe 20 through the rotary joint 167. The melted asphalt enters the crack through the rotating rod 18. The repair personnel push the moving base 1 to move through the self-locking universal wheels 23 by holding the grip 26, so that the asphalt conveying component 16 drives the perfusion pipe 20 to move. The moving base 1 moves through the fixed seat 7 and the limit slide rail 12, and the fixed seat 7 drives the reciprocating screw rod 8 to move through the bearing, so that the reciprocating nut sleeve 9 and the limit sliding sleeve 11 drive the moving plate 10 to move, and the mounting seat 13 drives the rotating shaft 14 to move through the bearing, so that the compaction roller 15 drives the rotating shaft 14 to rotate in the mounting seat 13 through the bearing, and the compaction roller 15 compacts the perfused asphalt. When there is a strong natural wind during perfusion, the driving motor 3 drives the output end stirring shaft 4 to rotate in the reverse direction, so that the stirring shaft 4 drives the stirring paddle 5 and the worm 61 to rotate in the reverse direction. The worm 61 drives the engaged worm wheel 62 to rotate, and the worm wheel 62 drives the rotating shaft 63 to rotate in the reverse direction. The horizontal plane of the ratchet sleeve one 66 pushes the horizontal plane of the ratchet sleeve two 67, so that the ratchet sleeve two 67 drives the connecting shaft 65 to rotate through the limit block and the limit groove, and the connecting shaft 65 drives the reciprocating screw rod 8 to rotate in the fixed seat 7 through the bearing through the bevel gear 610, so that the reciprocating nut sleeve 9 drives the moving plate 10 to move to the left. The moving plate 10 drives the limit sliding sleeve 11 and the mounting seat 13 to move to the left. The limit sliding sleeve 11 slides on the surface of the limit slide rail 12, so that the limit sliding sleeve 11 and the limit slide rail 12 guide the moving direction of the moving plate 10. The mounting seat 13 drives the rotating shaft 14 to move to the left through the bearing, so that the rotating shaft 14 drives the compaction roller 15 to move to the left. At the same time, the moving plate 10 drives the driving tooth plate 21 to move to the left through the angle limiting component 22, so that the compaction roller 15 approaches the perfusion pipe 20. When the pushing plate 24 drives the driving tooth plate 21 to contact the rotating gear 19, the driving tooth plate 21 pushes the rotating gear 19 to rotate, and the rotating gear 19 drives the rotating rod 18 to rotate in the fixed plate 17 through the bearing, so that the rotating rod 18 drives the perfusion pipe 20 to turn over, and the perfusion pipe 20 drives the mounting sleeve 221 to perform a circular motion.The installation sleeve 221 is driven to move the limit spring 222 and the limit bump 223, so that the inclined surface of the triangular block 224 pushes the inclined surface of the limit bump 223, causing the limit bump 223 to contract into the interior of the installation sleeve 221 and compress the limit spring 222. When the rotating rod 18 drives the perfusion tube 20 to flip to an appropriate angle, the resilience of the limit spring 222 is used to push the limit bump 223 to re-insert between the triangular blocks 224, so that the triangular blocks 224 limit the position of the installation sleeve 221, and the flipping angle of the perfusion tube 20 can be limited by the rotating rod 18. During the rotation process, the perfusion tube 20 drives the rotating tube 1674 to rotate, and the rotating tube 1674 drives the rotating sleeve 1673 to rotate through the sealing bearing 1672. Moreover, the flipping angle of the perfusion tube 20 does not exceed thirty degrees during this process. After the perfusion tube 20 is tilted for perfusion, the compacting roller 15 can compact the poured asphalt within a short time after perfusion.

[0042] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
