Description

Technical Field

[0001] The present invention relates to the technical field of permafrost roadbed repair and maintenance, and in particular to permafrost sheet rock roadbed repair and maintenance equipment and a method thereof. Background Art

[0002] The core function of ventilation in permafrost-affected rubble roadbeds, through holes in the outer walls of ventilation ducts, is to enhance heat exchange efficiency. These holes allow low-temperature air to flow not only within the ducts but also penetrate directly into the pores of the rubble layer, forming a crisscrossing heat dissipation network. Compared to traditional closed ducts that rely solely on heat conduction from the pipe wall, the through-hole structure significantly increases the contact area between the cold air and the rubble layer, significantly improving convective heat transfer. However, in actual service, the rubble roadbeds experience internal pore closure due to disturbances from overhead loads, localized water erosion and freezing, and the ineffectiveness of convective heat exchange. This leads to thawing of the underlying permafrost, particularly in gravel areas, which impacts the effectiveness of engineering treatment measures.

[0028] In summary, the permafrost sheet block roadbed repair and maintenance equipment and method thereof, when in use, allows the strong plateau wind to pass through the ventilation channel 65 and be input into the permafrost sheet block layer 2 through the through-holes on the outer wall of the ventilation pipe 3 to cool down the temperature; The traffic volume of vehicles on a certain road section is constant. According to the traffic volume of vehicles on a certain road section, during construction, a suitable transmission ratio of the small gear 30 and the large gear 29 and the thread pitch of the outer side of the first reciprocating screw 33 are selected to automatically clean the gaps between the pieces of stone in the frozen soil piece layer 2 at regular intervals. When the car is traveling on the two lanes at the top of the frozen soil block layer 2, the tires at the bottom of the vehicle press the speed bump 8, causing the speed bump 8 to move downward, so that the speed bump 8 drives the pressure block 7 to squeeze the first airbag 9, and the gas inside the first airbag 9 is input into the pressurized chamber 11 through the first pipe 12. When the tires at the bottom of the vehicle leave the speed bump 8, the first spring 6 pushes the speed bump 8 to drive the pressure block 7 to move upward, so that the pressure block 7 drives the first airbag 9 to deploy, so that the outside air is sucked into the first airbag 9 through the intake pipe 66. This reciprocating cycle continuously inputs gas into the pressurized chamber 11, so that pressurized gas is stored inside the pressurized chamber 11; When the speed reduction belt 8 moves downward and drives the first rack 31 to move downward, the first rack 31 drives the first gear 32 to rotate, so that the first gear 32 drives the rotating shaft 28 and the pinion 30 to rotate, so that the pinion 30 drives the large gear 29 and the first reciprocating screw 33 to rotate, so that the first reciprocating screw 33 drives the second rack 34 to move. When the speed reduction belt 8 drives the first rack 31 to move upward, the first rack 31 cannot drive the rotating shaft 28 and the pinion 30 to rotate through the first gear 32 and the one-way bearing. The transmission ratio of the transmission structure can be set to achieve that when the speed reduction belt 8 moves up and down a total of 20 times, the second rack 34 contacts the second gear 36, so that the second gear 36 drives the threaded rod 35 to rotate. , so that the threaded rod 35 drives the first piston column 38 to move downward, so that the liquid inside the first piston cylinder 37 enters the first liquid sac 22 through the third pipe 21, and enters the fifth pipe 57 through the third pipe 21, so that the fifth pipe 57 inputs liquid into the third liquid sac 60, so that the third liquid sac 60 expands and pushes the guide block 61 to drive the scraper 63 to move, so that the scraper 63 pushes the debris at the bottom of the inner cavity of the air groove 26 below the sealing plate 24 to the outside of the air box 25. At the same time, the expansion of the first liquid sac 22 pushes the sealing plate 24 down into the inner cavity of the air groove 26 until the bottom end of the sealing plate 24 contacts the bottom of the inner cavity of the air groove 26, thereby sealing the interior of the air box 25, thereby sealing both ends of the ventilation pipe 3; During this process, as the first reciprocating screw 33 drives the second rack 34 to move, pressurized air is continuously added to the pressurized chamber 11 through the first airbag 9. When the second rack 34 disengages from the second gear 36, the speed reducer 8 moves up and down a total of 25 times, so that the sealing plate 24 seals the inside of the air box 25. The pressure inside the pressurized chamber 11 is greater than the supporting force of the second spring 18 on the piston block 19. At this time, the piston block 19 pushes the stopper 17 to move, so that the stopper 17 passes through the arc inclined surface on one side of the limit block 50. One end of the stopper 17 pushes the limit block 50 to squeeze the fifth spring 49, so that one end of the stopper 17 moves to the rear of the limit block 50, and then the fifth spring 49 pushes the limit block 50 to move downward, so that the bottom end of the limit block 50 will stop The block 17 is limited, so that the gas inside the pressurized chamber 11 enters the piston chamber 13 through the connector 15, and then enters the second pipe 14, so that the gas enters the air duct 65 through the second pipe 14, and enters the through hole through the air duct 65, and blows away the dust and mud blocked in the gaps between the blocks in the frozen soil block layer 2. In this process, even if there are vehicles traveling on this section of road, when the speed bump 8 is driven up and down, air is continuously input into the pressurized chamber 11 through the first airbag 9 for cleaning work. At this time, the first reciprocating screw 33 continuously drives the second rack 34 to move. When the speed bump 8 moves up and down 35 times in total, the first reciprocating screw 33 drives the second rack 34 to reset. When When the speed reduction belt 8 moves up and down a total of 39 times, the second rack 34 drives the third rack 42 to contact the third gear 41, so that the third rack 42 drives the third gear 41 to drive the second reciprocating screw 40 to rotate through the second one-way bearing, so that the second reciprocating screw 40 drives the second piston column 43 to move downward first and then upward, so that the liquid inside the second liquid capsule 46 is first sucked into the second piston cylinder 39 through the fourth pipe 44, so that the fourth spring 48 pushes the storage box 47 to drive the limit block 50 to move upward, so that the bottom end of the limit block 50 no longer blocks the stop block 17. At this time, because the air pressure inside the pressurized chamber 11 returns to normal pressure, the second spring 18 pushes the stop block 17 and the piston block 19 to move, disconnecting the second pipe 14 from the connector 15. , then the liquid inside the second piston cylinder 39 enters the second liquid capsule 46 through the fourth pipe 44, so that the second liquid capsule 46 drives the storage box 47 to move downward, so that the storage box 47 drives the bottom end of the limit block 50 to be inserted into the driving chamber 16, so that the limit block 50 is in a standby state, so that the next limiting and fixing work of the stopper 17 and the piston block 19 can be performed. When the third rack 42 moves, the second rack 34 moves synchronously, thereby driving the second gear 36 to reset and rotate through the second rack 34, so that the second gear 36 drives the threaded rod 35 to reset and rotate, so that the threaded rod 35 drives the first piston column 38 to move upward, so that the gas inside the first liquid capsule 22, the fifth pipe 57 and the third liquid capsule 60 is extracted, so that the third liquid capsule 60 contracts.The sixth spring 62 pushes the guide block 61, driving the scraper 63 to reset and move, causing the first liquid sac 22 to contract. The third spring 23 pushes the sealing plate 24 upward, opening the interior of the air groove 26. When the second rack 34 separates from the second gear 36, and the third rack 42 separates from the third gear 41, the speed reducer 8 moves up and down a total of 45 times, and then continues to move to the maximum stroke at the rightmost end of the first reciprocating screw 33. At this time, the entire cleaning process involves the speed reducer 8 moving up and down a total of 60 times.
