Description

Technical Field

[0001] This invention relates to the field of road repair technology, and in particular to a rapid repair device for highway pavements. Background Technology

[0002] As a vital infrastructure for transportation, highways are constantly subjected to the impact of vehicle loads, natural environmental erosion, and human wear and tear, making them highly susceptible to damage such as potholes and cracks. If damaged road surfaces are not repaired in a timely manner, the damaged areas will gradually expand, affecting not only the comfort and safety of highway travel but also increasing subsequent maintenance costs. Therefore, rapid road repair equipment plays a crucial role in highway maintenance.

[0003] Currently, while existing rapid road surface repair equipment can fill and repair damaged road surfaces, its compaction mechanism has significant shortcomings. In existing technologies, pressure rollers are mostly installed using a fixed-rotation method, typically connected to the support frame via bolts, bearing clamps, or other traditional structures. This installation method makes disassembly, replacement, and subsequent maintenance and cleaning of the pressure rollers extremely cumbersome, requiring operators to use specialized tools to gradually disassemble the fixed structure, resulting in low operational efficiency and high labor costs. Furthermore, during the disassembly process, the lack of an effective support mechanism allows the pressure rollers to easily fall directly from the equipment to the ground after unlocking, leading to surface wear, internal structural damage, reduced roller lifespan, and increased equipment maintenance costs.

[0004] Therefore, rapid repair equipment for highway pavements is provided to address the aforementioned problems. Summary of the Invention

Through the linkage between the translation and adjustment mechanism, locking plug, and unlocking unit, the bracket automatically moves to the bottom of the pressure roller for support during unlocking and disassembly. Combined with the soft cushioning on the inner wall of the bracket, this effectively reduces the drop height and impact force of the pressure roller, preventing surface wear and internal structural damage, thus reducing equipment maintenance costs. Furthermore, through the linkage between the oil injection mechanism and the push plate of the translation and adjustment mechanism, the lifting power of the lifting unit drives the oil injection mechanism to automatically complete the oil injection operation, eliminating the need for an additional power source and manual intervention. This ensures uniform lubrication at the rotating connection points of the pressure roller, preventing issues such as rotational jamming and accelerated wear. Simultaneously, automatic oil replenishment further reduces maintenance workload. The aforementioned actions of unlocking and locking the pressure roller, translating and receiving the bracket, and oiling the oiling mechanism are all driven by the lifting part of the compaction mechanism itself, eliminating the need for multiple independent power sources and improving the practicality and economy of the equipment.

[0021] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0022] like Figures 1-12 As shown, a rapid repair device for highway pavement includes a vehicle body 1.

[0023] The vehicle body 1 is equipped with a filling mechanism 2 and a compaction mechanism 3.

[0024] The compaction mechanism 3 includes a fixed frame 301, a lifting part 302, and a pressure roller 303; the lifting part 302 is fixed to the top of the fixed frame 301, and a movable frame 305 is provided at the bottom of the lifting part 302. Locking plugs 9 are provided on both sides of the movable frame 305. Circular holes 3031 are opened at the middle of both ends of the pressure roller 303, and the locking plugs 9 are engaged with the circular holes 3031.

[0025] The top inner side of the fixing frame 301 is provided with an unlocking part.

[0026] The fixed frame 301 is equipped with a translation adjustment mechanism 6 on both sides. The translation adjustment mechanism 6 is connected to a bracket 7, and the bracket 7 is located on both sides of the bottom of the pressure roller 303.

[0027] like Figures 1-3 As shown, the filling mechanism 2 includes a hopper 201 fixed to the top of the vehicle body 1. A discharge pipe 204 is fixedly connected to one side of the bottom of the hopper 201. The discharge pipe 204 is located on the side below the vehicle body 1 and is equipped with an electrically controlled valve 205. A feeding port 202 is connected to the top of the hopper 201 and a motor 203 is fixedly installed on the top of the hopper 201. The motor 203 is connected to a stirring shaft 206 located inside the hopper 201 and is equipped with stirring blades.

[0028] Casters 101 are installed at the four corners of the bottom of the vehicle body 1; a handrail 4 is installed on the top of one side of the vehicle body 1. By pushing or pulling the handrail 4, the vehicle body 1 can be moved on the road surface by the casters 101 at the four corners.

[0029] When repairing a road surface, the entire equipment is moved to the damaged area (such as a pothole) and the bottom of the discharge pipe 204 is aligned with the pothole. Then, the electrically controlled valve 205 is opened, and the repair material in the hopper 201 is discharged through the discharge pipe 204 and enters the pothole. After the pothole is filled, the electrically controlled valve 205 is closed to complete the filling repair.

[0030] The hopper 201 is equipped with a stirring structure to agitate the repair material, ensuring its uniformity. Specifically, a motor 203 drives a stirring shaft 206 to rotate, and the stirring blades on the shaft 206 agitate the repair material. In practice, a heating structure (such as an electric heating element or wire) is installed inside the hopper 201 wall to heat the repair material in real time, preventing it from solidifying.

[0031] like Figure 4 As shown, the compaction mechanism 3 also includes a plate 304; the fixing frame 301 is fixed to the top of the vehicle body 1; the lifting part 302 is a cylinder or a hydraulic cylinder; the top surface of the plate 304 is fixed to the bottom end of the output shaft of the lifting part 302; the plate 304 is located above the movable frame 305; a guide post 307 is fixed to the top of the movable frame 305; a guide sleeve 308 is fixed to the top of the plate 304; the guide post 307 and the guide sleeve 308 are slidably sleeved; a first spring 306 is sleeved on the guide post 307 and the first spring 306 is located between the plate 304 and the movable frame 305; a baffle 309 is fixedly installed on the guide post 307 and the baffle 309 is located above the guide sleeve 308.

[0032] After the road surface is filled with filler, it is compacted by the compaction mechanism 3. Specifically, the lifting part 302 extends, driving the pressure roller 303 to descend and contact the ground. Then, the lifting part 302 continues to extend, causing the plate 304 to move downward. However, the pressure roller 303 is blocked by the ground, and the pressure roller 303 and the movable frame 305 cannot continue to move downward. As a result, the plate 304 moves closer to the movable frame 305 and compresses the first spring 306. The compression force of the first spring 306 acts on the movable frame 305, causing the pressure roller 303 to press firmly against the ground. Then, maintenance personnel push the entire equipment to move on the ground, causing the pressure roller 303 to roll over the filler position, thus achieving compaction.

[0033] After compaction, the lifting part 302 retracts, causing the plate 304 to move upward. The plate 304 moves away from the movable frame 305, causing the first spring 306 to reset. The first spring 306 releases the pressure on the movable frame 305, and the lifting part 302 continues to drive the plate 304 upward until the baffle 309 comes into contact with the top of the guide sleeve 308. Subsequently, the lifting part 302 drives the plate 304 upward, lifting the baffle 309 through the guide sleeve 308. The guide column 307 causes the movable frame 305 and the pressure roller 303 to move upward together, separating the pressure roller 303 from the ground. The equipment is then pushed to move on the ground, and the pressure roller 303 no longer rubs against the ground.

[0034] The design of the first spring 306 providing elastic pressure ensures the downward pressure of the pressure roller 303 during the compaction process, facilitating improved compaction effect. The design of the guide post 307 and guide sleeve 308 guides the movement of the movable frame 305 and the plate 304 towards or away from each other. After the pressure roller 303 detaches from the ground, the baffle 309 applies gravity to the guide sleeve 308 of the plate 304, preventing the first spring 306 from being stressed. The state of the pressure roller 303 separated from the ground is as follows... Figures 6-7 As shown, it should be noted that in this state, the pressure roller 303 is not at its highest position and can continue to move upward.

[0035] like Figure 4 As shown, a through groove 102 is provided on the vehicle body 1; the through groove 102 provides a passage position for the structure below the lifting part 302, so that the pressure roller 303 can be moved to the bottom of the vehicle body 1 to press the ground, or to the top of the vehicle body 1.

[0036] The vehicle body 1 of this invention is equipped with a power supply and control cabinet, which can be used for power supply and electrical control.

[0037] like Figures 7-8As shown, the locking plug 9 includes a pressure-bearing inclined plate 901 and a side cylinder 904 fixed to the outer wall of the movable frame 305; the side cylinder 904 is slidably fitted with a round shaft 905; one end of the round shaft 905 located inside the side cylinder 904 has a square hole 906, a square post 907 is fixed inside the side cylinder 904, the square post 907 is inserted into the square hole 906, a hole is formed in the middle of the square post 907, and the hole penetrates the side of the side cylinder 904 away from the movable frame 305, a straight rod 903 is slidably fitted into the hole, and one end of the straight rod 903 is connected to the round shaft 905. The square column 907 is fixed, with a groove 910 at its end. A third spring 908 is installed in the groove 910 and sleeved on the straight rod 903. The square column 907 is elastically connected to the round shaft 905 via the third spring 908 (the two ends of the third spring 908 abut against the wall of the groove 910 and the wall of the square hole 906, respectively, to achieve the elastic connection between the square column 907 and the round shaft 905). A connecting frame 902 is fixed to one end of the straight rod 903, and a pressure-bearing inclined plate 901 is fixed to the connecting frame 902. The unlocking part is located above the pressure-bearing inclined plate 901. A sealing ring 909 is fixedly sleeved on one end of the round shaft 905 inside the side cylinder 904.

[0038] like Figure 7 As shown, the unlocking part includes a squeezing block 8; a connecting rod 801 is fixed to the top of the squeezing block 8, and the connecting rod 801 is fixed to the inner side of the top of the fixing frame 301. A second squeezing inclined surface 802 is provided on one side of the squeezing block 8, and a pressure-receiving inclined surface 9011 adapted to the second squeezing inclined surface 802 is provided on one side of the pressure-receiving inclined plate 901.

[0039] The unlocking part and locking plug 9 facilitate the locking and unlocking of the pressure roller 303, thereby making it easy to disassemble and replace the pressure roller 303.

[0040] When pressure roller 303 needs to be replaced, first separate pressure roller 303 from the ground, such as... Figures 6-7As shown, the movable frame 305 and the pressure roller 303 move upward together, and the pressure plate 901 moves closer to the extrusion block 8. The pressure plate 901 is pushed by the second extrusion inclined surface 802, causing the pressure plate 901 to move away from the movable frame 305. The pressure plate 901 drives the round shaft 905 to move into the side cylinder 904 through the connecting frame 902 and the straight rod 903. The round shaft 905 automatically separates from the round hole 3031, and at the same time, the third spring 908 is compressed, which automatically releases the lock of the pressure roller 303. The pressure roller 303 falls down by gravity and separates from the movable frame 305. After disassembly, the reinstallation of the pressure roller 303 is as follows: Place the pressure roller 303 inside the movable frame 305, aligning the circular hole 3031 with the circular shaft 905. Then, the lifting part 302 lowers the movable frame 305, separating the pressing block 8 from the pressure inclined plate 901. The pressure inclined plate 901, connecting frame 902, straight rod 903, and circular shaft 905 are reset by the elastic force of the third spring 908. The circular shaft 905 is then inserted into the circular hole 3031, completing the installation of the pressure roller 303. It should be noted that a stop post is provided on the inner top of the movable frame 305. When the circular hole 3031 at the end of the pressure roller 303 is aligned with the circular shaft 905, the pressure roller 303 fits against the bottom end of the stop post to prevent it from being in place, thus maintaining the alignment of the circular hole 3031 with the circular shaft 905.

[0041] With the above design, the pressure roller 303 can be installed and disassembled without manual unlocking and locking. Moreover, unlocking and relocking are powered by the lifting unit 302, eliminating the need for an additional power source.

[0042] like Figure 7 , Figure 11 as well as Figure 12 As shown, the translation adjustment mechanism 6 is installed on the side wall of the fixed frame 301, and a protective cover 5 is provided on the outer side wall of the fixed frame 301; the translation adjustment mechanism 6 includes a push plate 601; the push plate 601 is disposed on the inner side of the fixed frame 301, the push plate 601 is connected to a transmission part, and the transmission part is disposed inside the protective cover 5, and the transmission part is connected to the bracket 7.

[0043] The transmission unit includes a first rack 602 fixed to the push plate 601. The first rack 602 is slidably connected to a first guide groove formed on the side wall of the fixing frame 301. The first rack 602 is meshed with a first gear 603. A first rotating shaft 611 is fixed to the middle of the first gear 603, and the first rotating shaft 611 is rotatably mounted inside the protective cover 5. A first pulley 604 is fixedly sleeved on the first rotating shaft 611. A second rotating shaft 612 is rotatably mounted inside the protective cover 5, and a second pulley 613 is fixedly sleeved on the second rotating shaft 612. The second gear 606 is connected to the second rack 607, which is meshed with the first pulley 604 and the second pulley 613. The second rack 607 is fixed with two movable columns 608. The movable columns 608 are slidably connected to the second guide groove opened on the side wall of the fixed frame 301, and the second guide groove passes through the side wall of the vehicle body 1. The movable columns 608 are fixed to the bracket 7. The second rack 607 is fixed with a side seat 609, which is elastically connected to the side wall of the fixed frame 301 by a second spring 610.

[0044] The diameter of the first pulley 604 is larger than the diameter of the second pulley 613, and the diameters of the first gear 603 and the second gear 606 are equal.

[0045] The transmission part of a single translation adjustment mechanism 6 connects two brackets 7, that is, each of the two movable columns 608 is connected to one bracket 7. For example... Figure 10 As shown, there is a gap between the two brackets 7. When the compaction mechanism 3 presses the ground, the gap is used to allow the locking plugs 9 on both sides of the fixed bracket 301 to pass through, so as to avoid obstruction.

[0046] It should also be noted that when the pressure plate 901 of the locking plug 9 is not being pressed by the pressing block 8, such as Figure 7 As shown, the bracket 7 is close to the inner wall of the fixed frame 301 and does not obstruct the pressure roller 303.

[0047] As the pressure plate 901 moves closer to the extrusion block 8, the connecting frame 902 moves to the side of the push plate 601. When the pressure plate 901 is compressed by the extrusion block 8, the pressure plate 901 drives the connecting frame 902 to move closer to the inner wall of the fixed frame 301. The connecting frame 902 pushes the push plate 601, causing the push plate 601 to move closer to the inner wall of the fixed frame 301. The push plate 601 drives the first rack 602 to move together, and through the meshing transmission between the first rack 602 and the first gear 603, the first rotating shaft 611 drives the first pulley 604 to rotate. The transmission belt 605 drives the second pulley 613 to rotate the second shaft 612 and the second gear 606. The meshing of the second gear 606 and the second rack 607 causes the second rack 607 to move the movable column 608 and the bracket 7 together. The bracket 7 moves away from the inner wall of the fixed frame 301 and moves to below the pressure roller 303. When the pressure roller 303 falls, it is caught by the bracket 7 to prevent it from falling directly to the ground and reduce the fall height. The soft pad 702 inside the bracket 7 also helps to catch the roller, reducing the impact and thus reducing damage.

[0048] The pressure roller 303 falls into the bracket 7. The pressure roller 303 is manually removed for maintenance and cleaning or directly replaced with a new pressure roller 303.

[0049] When the pressure roller 303 is reinstalled, the locking plug 9 resets, the connecting frame 902 separates from the push plate 601, and the translation adjustment mechanism 6 resets through the elastic force of the second spring 610. The second spring 610 drives the second rack 607 and the movable column 608 to reset and move together. The movable column 608 drives the bracket 7 to move closer to the inner wall of the fixed frame 301. Through the meshing transmission of the second rack 607 and the second gear 606, the second rotating shaft 612 drives the second pulley 613 to rotate. The second pulley 613 drives the first pulley 604 to rotate through the transmission belt 605. The first pulley 604 drives the first rotating shaft 611 and the first gear 603 to rotate. Then, through the meshing transmission of the first gear 603 and the first rack 602, the first rack 602 drives the push plate 601 away from the inner wall of the fixed frame 301 to reset.

[0050] With the above design, when the pressure roller 303 is disassembled, the bracket 7 automatically moves to the bottom of the pressure roller 303 to receive it; when the pressure roller 303 is installed, the pressure roller 303 automatically resets and moves away from the bottom of the pressure roller 303 to avoid obstruction. This facilitates the disassembly and assembly of the pressure roller 303. At the same time, the bracket 7 automatically moves and resets without manual operation, and the translation and adjustment mechanism 6 is driven by the locking plug 9, so that the translation and adjustment mechanism 6 does not require additional power.

[0051] The bracket 7 includes a frame 701, and a soft pad 702 is fixedly adhered to the inner wall of the frame 701.

[0052] like Figure 8 As shown, a first pressing slope 6011 is provided on one side of the bottom of the push plate 601. When the movable frame 305 and the locking plug 9 rise together, the first pressing slope 6011 is used to press the end of the plug rod 1301 of the oiling mechanism 13, so that the oiling mechanism 13 automatically injects oil for lubrication without the need for an additional power source.

[0053] like Figure 8 As shown, an oil injection mechanism 13 is installed inside the straight rod 903; an oil delivery channel 10 is provided inside the round shaft 905, and the oil delivery channel 10 is connected to the oil injection mechanism 13; a plurality of evenly distributed spherical holes 11 are opened on the cylindrical surface of the round shaft 905, and the spherical holes 11 are connected to the oil delivery channel 10; and ball bearings 12 are provided inside the spherical holes 11.

[0054] like Figure 9 As shown, the oil injection mechanism 13 includes a stopper rod 1301; an oil injection chamber 1302 and an oil storage chamber 1310 are provided in the straight rod 903; a piston 1305 is fitted in the oil injection chamber 1302 and the piston 1305 is fixed to the stopper rod 1301; an oil outlet 1303 is provided at one end of the straight rod 903 and the oil outlet 1303 is connected to the oil injection chamber 1302; a first one-way valve 1304 is installed in the oil outlet 1303; the oil injection chamber 1302 is connected to the oil storage chamber 1310 through an oil inlet pipe 1308 and a second one-way valve 1309 is installed in the oil inlet pipe 1308; a fixed plate 1306 is fixedly installed on the stopper rod 1301; one side of the fixed plate 1306 is elastically connected to the side wall of the oil storage chamber 1310 through a fourth spring 1307 and the fourth spring 1307 is sleeved on the stopper rod 1301.

[0055] A groove is provided between the oil injection chamber 1302 and the oil storage chamber 1310. The plug rod 1301 passes through the groove, and a sealing ring is provided on the groove wall. The plug rod 1301 passes through the oil storage chamber 1310. A through hole is opened on one side of the connecting frame 902. The plug rod 1301 passes through the through hole, and a sealing ring is also provided in the through hole to seal the oil storage chamber 1310.

[0056] The oil storage chamber 1310 is connected to the oil filling port 1311, and the oil filling port 1311 is provided with a sealing cap.

[0059] The above-mentioned lubrication is performed as follows: Figure 8In the indicated state, the lifting part 302 drives the pressure roller 303 to move upward, and the oil injection mechanism 13 moves upward together. The spherical surface at the end of the stopper rod 1301 moves to the first extrusion slope 6011 at the bottom of the push plate 601. Through the extrusion of the first extrusion slope 6011, the stopper rod 1301 and the piston 1305 move together. The piston 1305 pushes the oil in the oil injection chamber 1302. The oil enters the oil supply channel 10 through the oil outlet 1303 and the first one-way valve 1304, and then enters the spherical hole 11 to provide lubrication for all the balls 12. During the above process, the fixed plate 1306 moves together with the stopper rod 1301 and compresses the fourth spring 1307. After lubrication, the lifting unit 302 drives the pressure roller 303 to move downward, the stopper rod 1301 separates from the first extrusion inclined surface 6011, and the stopper rod 1301 and piston 1305 are reset by the elastic force of the fourth spring 1307. The oil injection chamber 1302 is sucked, so that the oil in the oil storage chamber 1310 enters the oil injection chamber 1302 through the oil inlet pipe 1308 and the second one-way valve 1309 to replenish the oil injection chamber 1302. Automatic oil injection lubrication is achieved through the above design.

[0060] In summary, the present invention provides a compaction mechanism 3, which can compact the road repair area. The pressure roller 303 in the compaction mechanism 3 is easy to replace. When the pressure roller 303 is replaced, it can be automatically caught if it falls to the ground, and the rotating installation position of the pressure roller 303 can be automatically lubricated. Moreover, the replacement, catching and automatic lubrication are all driven by the lifting part 302, so there is no need to set up too many power sources.
