Description

Technical Field

[0001] This utility model relates to the field of highway maintenance technology, specifically a highway maintenance pothole treatment device. Background Technology

[0002] As a core infrastructure of the transportation system, the integrity of highway pavement directly affects traffic safety and transportation efficiency. Under the influence of long-term vehicle loads, natural environmental erosion, and material aging, road surfaces are prone to potholes, depressions, and other defects. If not repaired in time, these defects will spread rapidly, exacerbating road damage, increasing the risk of traffic accidents, and significantly shortening the road's service life. Therefore, efficient pothole repair is a crucial aspect of highway maintenance.

[0003] Currently, highway pothole repair is mainly divided into two categories: manual repair and mechanical repair. Traditional manual repair requires manual cleaning of potholes, mixing of repair materials, and manual filling and compaction. This method has the problems of low work efficiency and high labor intensity. In addition, the materials mixed manually are not evenly mixed and the filling density is insufficient, resulting in low bonding strength at the repair site, easy secondary damage, and short repair life.

[0004] While existing mechanical repair devices have improved operational efficiency to some extent, they still have certain technical shortcomings: First, the material mixing effect is poor. The mixing structure is mostly a single horizontal mixing, which cannot achieve three-dimensional uniform mixing of materials. Moreover, material residue is easily left on the inner wall of the mixing tank, making it difficult to clean. Long-term use will affect the quality of the repair materials. Second, the flexibility of operation and the convenience of storage are insufficient. Pipelines such as hot air pipes and material conveying pipes lack effective positioning mechanisms, making them easy to get tangled during storage. The angle and distance can be limited during use, and components such as nozzles and pouring heads do not have special protective structures, making them susceptible to damage from impacts. Utility Model Content

[0005] To address the above problems, the purpose of this utility model is to provide a road maintenance pothole treatment device that solves the problems of: most mixing structures are single transverse mixing, which cannot achieve three-dimensional uniform mixing of materials; the inner wall of the mixing tank is prone to material residue, which is difficult to clean; insufficient operational flexibility and storage convenience; the lack of effective positioning mechanisms for pipelines such as hot air pipes and conveying pipes, which are prone to tangling during storage; limited adjustment of angle and distance during use; and the lack of special protection structures for components such as nozzles and pouring heads, which are easily damaged by collisions. When the mixing rod rotates under the drive of the mixing shaft, the cleaning brush slides along the inner wall of the mixing tank simultaneously, continuously scrubbing the inner wall of the tank to reduce the adhesion and residue of materials on the tank wall. During the rotation of the mixing shaft, the sleeve pipe synchronously drives the mixing rod to make a circular motion, which performs transverse mixing of materials in the mixing tank. At the same time, the mixing column on the mixing rod performs longitudinal tumbling of materials, achieving three-dimensional uniform mixing of materials.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a highway maintenance pothole treatment device, comprising a base assembly and a mixing assembly. The base assembly includes a base plate, a hot air blower, and a material pump. The mixing assembly includes a protective box. A mounting base is detachably connected to the top of the base plate by bolts. A hot air pipe is fixedly connected to the output end of the hot air blower via a flange. A nozzle is threadedly connected to the end of the hot air pipe away from the hot air blower. A material pump inlet is fixedly connected to a material extraction pipe via a clamp. The discharge end of the pump is fixedly connected to a conveying pipe by a clamp. The end of the conveying pipe away from the pump is connected to a pouring head by a threaded connection. The outer wall of the protective box is fixedly welded with a positioning ring by a bracket. The inner side of the protective box is fitted with a mixing tank by a positioning pin. The top of the protective box is fixedly connected to a motor by a shock-absorbing seat bolt. The inner side of the mixing tank is coaxially arranged with a stirring shaft. The outer wall of the stirring shaft is welded with sleeves at equal intervals along its height direction. The outer wall of the sleeves is symmetrically welded with stirring rods.

[0007] The beneficial effects of this utility model are as follows: the motor output torque drives the stirring shaft to rotate smoothly under the limit of the sealed bearing and the deep groove ball bearing. During the rotation of the stirring shaft, the stirring rod is synchronously driven to make a circular motion through the sleeve pipe, which stirs the material in the mixing tank laterally. At the same time, the mixing column on the stirring rod stirs the material longitudinally, realizing the three-dimensional uniform mixing of the material. When the stirring rod rotates under the drive of the stirring shaft, the cleaning brush slides along the inner wall of the mixing tank at the same time, continuously scrubbing the inner wall of the tank and reducing the adhesion and residue of the material on the tank wall.

[0008] In order for the hot air blower to output high-pressure hot air to blow away debris and loose materials in the pit:

[0009] As a further improvement to the above technical solution: the hot air duct is a corrugated flexible telescopic pipe, there are two hot air blowers which are detachably installed on the mounting base by bolts, the two hot air blowers are symmetrically arranged on the same side of the protective box, and the hot air blowers are electrically connected to the operation panel by wires.

[0010] The beneficial effects of this improvement are as follows: During operation, first push the device to the predetermined pit position, lock the self-locking universal wheel fixing device at the bottom of the base plate, then take out the nozzle from the protective cover, hold the hot air hose and adjust the nozzle to aim at the inner cavity of the maintenance pit, start the hot air blower control switch on the control panel, the hot air blower outputs high-pressure hot air to blow away debris and loose materials in the pit, and the corrugated flexible telescopic tube can flexibly adjust the working angle and distance of the nozzle.

[0011] To ensure that after the pump starts, it draws material from the mixing tank through the extraction pipe and then stably delivers it to the pouring head through the conveying pipe:

[0012] As a further improvement to the above technical solution: the material pump is detachably mounted on the mounting base by bolts, and the material pump is correspondingly arranged on the side of the protective box away from the hot air blower. The material pump is electrically connected to the operation panel through a flame-retardant wire. The material conveying pipe is a wear-resistant corrugated flexible telescopic pipe. The end of the material pump away from the material pump vertically penetrates the bottom wall of the mixing tank and is sealed and connected to the inner cavity of the mixing tank by a rubber sealing gasket. The top outer wall of the protective box is fixedly connected to a protective cover by bracket bolts. The positioning ring is an elastic clamping structure. The protective cover is an integrated anti-collision and dustproof structure.

[0013] The beneficial effects of this improvement are as follows: the positioning ring is used to limit and fix the hot air pipe and conveying pipe in the storage state to avoid pipe entanglement; the protective cover is used to fully protect the spray head and pouring head in the non-operation state; after cleaning the pothole and preheating and softening the inner wall and surrounding road surface of the pothole, after the material in the mixing tank is evenly mixed by the mixing shaft and mixing rod and maintained at the preset operating temperature by the heating plate, the pump control switch on the operation panel is started. After the pump starts, the material in the mixing tank is drawn through the pumping pipe and stably conveyed to the pouring head through the conveying pipe. The operator holds the conveying pipe and, through the adjustability of the corrugated flexible telescopic pipe, aligns the pouring head with the pothole and pours it evenly along the inner wall of the pothole to the center, ensuring that the material fills the pothole and is slightly higher than the original road surface by 1-2mm, and compacts it. After pouring, the matching compaction tool is immediately used to compact the material in the pothole in layers until the material is flush with the original road surface and dense without gaps, thus completing the pothole repair.

[0014] The repair kit is equipped with divided storage compartments for the categorized storage of repair tools, spare parts, and auxiliary consumables.

[0015] As a further improvement to the above technical solution: the bottom of the base plate is fixed with self-locking casters by wheel frame bolts, and the top of the base plate is detachably connected to two maintenance boxes by mounting seat bolts, with the two maintenance boxes symmetrically arranged at both ends of the protective box.

[0016] The beneficial effects of this improvement are as follows: the base plate is an integral steel structure, which provides stable installation support for the hot air blower, material pump, maintenance box and protective box. The maintenance box is equipped with partitioned storage compartments for classifying and storing maintenance tools, spare parts and auxiliary consumables.

[0017] To provide surround heating to the mixing tank and maintain the material inside at the preset operating temperature:

[0018] As a further improvement to the above technical solution: the protective box is fixed to the center of the top of the base plate by positioning pins and bolts. The protective box has fan-shaped clearance grooves at the four corners of its inner side. A heating plate is detachably installed on the inner side of the clearance groove by buckles and bolts. The heating plate is electrically connected to the operation panel by wires.

[0019] The beneficial effects of this improvement are as follows: after the material is added to the mixing tank, the heating plate is activated through the control panel. The heating plate generates heat after being powered on, which heats the mixing tank in a circular manner, keeping the material inside the tank at the preset operating temperature and preventing the material from condensing and affecting the conveying and repair effects.

[0020] To ensure that the material falls directly into the interior of the mixing tank, facilitating subsequent mixing by the stirring shaft and stirring rod:

[0021] As a further improvement to the above technical solution: two feed ports with dust covers are welded and fixed to the top of the protective box. The dust covers are threaded and screwed on. The bottom of the feed port penetrates vertically through the top wall of the mixing tank and communicates with the inner cavity of the mixing tank, extending to the middle of its inner side.

[0022] The beneficial effects of this improvement are as follows: Before operation, unscrew the dust cover and add the main material and auxiliary material through the two feed ports respectively. The material falls directly into the internal area of ​​the mixing tank, which facilitates the subsequent mixing by the stirring shaft and stirring rod. After the material is added, tighten the dust cover to prevent material from splashing and dust from entering during the mixing process.

[0023] In order to simultaneously tumble the material longitudinally with the mixing column on the stirring rod, so as to achieve three-dimensional uniform mixing of the material:

[0024] As a further improvement to the above technical solution: the upper end of the stirring shaft passes through the top wall of the protective box through a sealed bearing, and is coaxially and fixedly connected to the output end of the motor through a coupling. The motor is electrically connected to the operation panel through a wire. The bottom of the stirring shaft away from the motor is rotatably connected to the inner wall of the bottom surface of the mixing tank through a deep groove ball bearing.

[0025] The beneficial effects of this improvement are as follows: when the motor is started by the control panel, the motor output torque drives the stirring shaft to rotate smoothly under the limit of the sealed bearing and the deep groove ball bearing. During the rotation of the stirring shaft, the stirring rod is synchronously driven to make a circular motion through the sleeve pipe, which stirs the material in the mixing tank laterally. At the same time, the mixing column on the stirring rod stirs the material longitudinally, so as to achieve three-dimensional uniform mixing of the material.

[0026] To ensure the cleaning brush slides synchronously along the inner wall of the mixing tank, it continuously scrubs the inner wall of the tank, reducing material residue adhering to the tank wall:

[0027] As a further improvement to the above technical solution: cylindrical mixing columns are symmetrically welded and fixed to the outer wall of the stirring rod, and a cleaning brush is detachably connected to the end of the stirring rod away from the sleeve pipe by bolts. The bristles of the cleaning brush are made of wear-resistant nylon material and are in close contact with the inner wall of the mixing tank.

[0028] The beneficial effects of this improvement are as follows: when the stirring rod rotates under the drive of the stirring shaft, the cleaning brush slides synchronously along the inner wall of the mixing tank, continuously scrubbing the inner wall of the tank, reducing the adhesion and residue of materials on the tank wall. When the mixing tank needs to be cleaned after the device is used, unscrew the dust cover and inject the cleaning liquid, start the motor to drive the cleaning brush to rotate, and cooperate with the stirring rod and the mixing column to achieve a thorough cleaning of the inner wall of the tank. After cleaning, the waste liquid is discharged by the pump.

[0029] In summary, the beneficial effects of this solution are as follows: the cleaning brush slides synchronously along the inner wall of the mixing tank, continuously scrubbing the inner wall of the tank and reducing the adhesion and residue of materials on the tank wall; the motor output torque drives the stirring shaft to rotate smoothly under the limit of the sealed bearing and the deep groove ball bearing; during the rotation of the stirring shaft, the stirring rod is synchronously driven to make a circular motion through the sleeve pipe, which stirs the materials in the mixing tank laterally; at the same time, the mixing column on the stirring rod stirs the materials longitudinally, realizing the three-dimensional uniform mixing of materials.

The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.

[0038] like Figure 1-5 As shown, a pothole treatment device for highway maintenance includes a base assembly 1 and a mixing assembly 2. The base assembly 1 includes a base plate 11, a hot air blower 13, and a material pump 14. The mixing assembly 2 includes a protective box 21. The top of the base plate 11 is detachably connected to a mounting base 12 by bolts. The output end of the hot air blower 13 is fixedly connected to a hot air pipe 131 by a flange. The end of the hot air pipe 131 away from the hot air blower 13 is connected to a spray head 132 by a threaded connection. The inlet end of the material pump 14 is fixedly connected to a material extraction pipe 141 by a clamp. The discharge end of the material pump 14... A feed pipe 142 is fixedly connected by clamps. The end of the feed pipe 142 away from the pump 14 is connected to a pouring head 143 by a threaded connection. A positioning ring 15 is welded and fixed to the outer wall of the protective box 21 by a bracket. A mixing tank 22 is installed inside the protective box 21 by a positioning pin. A motor 23 is fixedly connected to the top of the protective box 21 by a shock-absorbing seat bolt. A stirring shaft 24 is coaxially arranged inside the mixing tank 22. A sleeve pipe 241 is welded and fixed at equal intervals along the height direction on the outer wall of the stirring shaft 24. A stirring rod 25 is symmetrically welded and fixed on the outer wall of the sleeve pipe 241.

[0039] The hot air duct 131 is a corrugated flexible telescopic tube. There are two hot air blowers 13, which are detachably installed on the mounting base 12 by bolts. The two hot air blowers 13 are symmetrically arranged on the same side of the protective box 21. The hot air blowers 13 are electrically connected to the operation panel through wires. When operating, first push the device to the predetermined pit position, lock the self-locking universal wheel fixing device at the bottom of the base plate 11, then take the nozzle 132 out from the protective cover 151, hold the hot air duct 131 and adjust the nozzle 132 to align with the inner cavity of the maintenance pit, and start the hot air blower 13 control switch on the operation panel. The hot air blower 13 outputs high-pressure hot air to blow away debris and loose materials in the pit. The corrugated flexible telescopic tube can flexibly adjust the working angle and distance of the nozzle 132.

[0040] The material pump 14 is detachably mounted on the mounting base 12 by bolts, and is correspondingly arranged on the side of the protective box 21 away from the hot air blower 13. The material pump 14 is electrically connected to the operation panel via a flame-retardant wire. The conveying pipe 142 is a wear-resistant corrugated flexible telescopic pipe. The end of the material extraction pipe 141 away from the material pump 14 vertically penetrates the bottom wall of the mixing tank 22 and is sealed and connected to the inner cavity of the mixing tank 22 by a rubber sealing gasket. The top outer wall of the protective box 21 is fixedly connected to the protective cover 151 by bracket bolts. The positioning ring 15 is an elastic clamping structure, and the protective cover 151 is an integrated anti-collision and dustproof structure. The positioning ring 15 is used to limit and fix the hot air pipe 131 and the conveying pipe 142 in the storage state to prevent the pipes from tangling. The protective cover 151 is used to protect the spray head 132 and the pouring head 143 in the non-operation state. After forming a full protective enclosure and completing the cleaning of the pothole and preheating and softening of the pothole's inner wall and surrounding road surface, the material in the mixing tank 22 is evenly mixed by the mixing shaft 24 and mixing rod 25, and maintained at the preset operating temperature by the heating plate 212. Then, the control switch of the material pump 14 on the operation panel is activated. After the material pump 14 starts, it draws the material in the mixing tank 22 through the material extraction pipe 141 and steadily conveys it to the pouring head 143 through the material delivery pipe 142. The operator holds the material delivery pipe 142 and, through the adjustability of the corrugated flexible telescopic pipe, aligns the pouring head 143 with the pothole and gradually and evenly pours the material along the inner wall of the pothole to the center, ensuring that the material fills the pothole and is slightly higher than the original road surface by 1-2mm. After compaction, the matching compaction tool is immediately used to compact the material in the pothole in layers until the material is flush with the original road surface and dense without gaps, thus completing the pothole repair.

[0041] The base plate 11 is fixed with self-locking casters at the bottom by wheel frame bolts. The top of the base plate 11 is detachably connected to two maintenance boxes 16 by mounting base 12 bolts. The two maintenance boxes 16 are symmetrically arranged at both ends of the protective box 21. The base plate 11 is an integral steel structure, which is used to provide stable installation support for the hot air blower 13, the material pump 14, the maintenance boxes 16 and the protective box 21. The maintenance boxes 16 are equipped with partitioned storage compartments for classifying and placing maintenance tools, spare parts and auxiliary consumables.

[0042] The protective box 21 is fixed to the top center of the base plate 11 by positioning pins and bolts. The protective box 21 has fan-shaped clearance grooves 211 at the four corners of its inner side. The inner side of the clearance grooves 211 is detachably installed with a heating plate 212 by buckles and bolts. The heating plate 212 is electrically connected to the operation panel by wires. After the material is added to the mixing tank 22, the heating plate 212 is activated by the operation panel. The heating plate 212 generates heat after being powered on, and heats the mixing tank 22 in a surrounding manner, so that the material in the tank maintains the preset operating temperature and avoids the material from condensing and affecting the conveying and repair effect.

[0043] The protective box 21 has two feed inlets 221 with dust covers welded to its top. The dust covers are threaded and screwed on. The bottom of each feed inlet 221 penetrates vertically through the top wall of the mixing tank 22 and communicates with the inner cavity of the mixing tank 22, extending to the middle of its inner side. Before operation, the dust covers are unscrewed, and the main material and auxiliary material are added through the two feed inlets 221 respectively. The material falls directly into the inner area of ​​the mixing tank 22, which facilitates the subsequent mixing by the stirring shaft 24 driving the stirring rod 25. After the material is added, the dust covers are tightened to prevent material from splashing and dust from entering during the mixing process.

[0044] The upper end of the stirring shaft 24 passes through the top wall of the protective box 21 through a sealed bearing and is coaxially fixedly connected to the output end of the motor 23 through a coupling. The motor 23 is electrically connected to the operation panel through a wire. The bottom of the stirring shaft 24 away from the motor 23 is rotatably connected to the inner wall of the bottom surface of the mixing tank 22 through a deep groove ball bearing. The motor 23 is started by the operation panel. The output torque of the motor 23 drives the stirring shaft 24 to rotate smoothly under the limit of the sealed bearing and the deep groove ball bearing. During the rotation of the stirring shaft 24, the sleeve pipe 241 synchronously drives the stirring rod 25 to make a circular motion, which stirs the material in the mixing tank 22 laterally. At the same time, the mixing column 251 on the stirring rod 25 stirs the material longitudinally, so as to achieve three-dimensional uniform mixing of the material.

[0045] Cylindrical mixing columns 251 are symmetrically welded and fixed to the outer wall of the stirring rod 25. A cleaning brush 252 is detachably connected to the end of the stirring rod 25 away from the sleeve 241 by bolts. The bristles of the cleaning brush 252 are made of wear-resistant nylon and are in close contact with the inner wall of the mixing tank 22. When the stirring rod 25 rotates under the drive of the stirring shaft 24, the cleaning brush 252 slides synchronously along the inner wall of the mixing tank 22 to continuously scrub the inner wall of the tank, reducing the adhesion and residue of materials on the tank wall. When the mixing tank 22 needs to be cleaned after the device is used, the dust cover is unscrewed and the cleaning liquid is injected. The motor 23 is started to drive the cleaning brush 252 to rotate. With the stirring of the stirring rod 25 and the mixing column 251, the inner wall of the tank is thoroughly cleaned. After cleaning, the waste liquid is discharged by the pump 14.

[0046] The working principle of this utility model is as follows: Before operation, unscrew the dust cover and add the main material and auxiliary material through the two feed inlets 221 respectively. The material falls directly into the internal area of ​​the mixing tank 22, which facilitates the subsequent mixing by the stirring shaft 24 driving the stirring rod 25. After the material is added, tighten the dust cover to prevent material splashing and dust from entering during the mixing process. During operation, first push the device to the predetermined pit position, lock the self-locking universal wheel fixing device at the bottom of the base plate 11, then take out the blower head 132 from the protective cover 151, hold the hot air hose 131 and adjust the blower head 132 to the inner cavity of the curing pit, and start the hot air blower 13 control switch on the operation panel. The hot air blower 13 outputs high-pressure hot air to blow away debris and loose materials in the pit. The corrugated flexible telescopic hose can flexibly adjust the blower head 132. At the operating angle and distance of 32, after the material is added to the mixing tank 22, the heating plate 212 is activated via the control panel. The heating plate 212 generates heat, providing a surround heating effect on the mixing tank 22, maintaining the material inside at the preset operating temperature and preventing material condensation from affecting conveying and repair. The motor 23 is then activated via the control panel. The motor 23 outputs torque to drive the stirring shaft 24 to rotate smoothly under the constraints of the sealed bearing and deep groove ball bearing. During the rotation of the stirring shaft 24, the sleeve 241 synchronously drives the stirring rod 25 to perform a circular motion, horizontally stirring the material inside the mixing tank 22. Simultaneously, the mixing column 251 on the stirring rod 25 vertically tumbles the material, achieving three-dimensional uniform mixing. As the stirring rod 25 rotates under the drive of the stirring shaft 24, it cleans... Brush 252 slides synchronously along the inner wall of mixing tank 22, continuously scrubbing the inner wall of the tank to reduce material adhesion and residue on the tank wall. When the mixing tank 22 needs to be cleaned after the device is used, unscrew the dust cover and inject cleaning fluid. Start motor 23 to drive cleaning brush 252 to rotate. With the agitation of stirring rod 25 and mixing column 251, the inner wall of the tank is thoroughly cleaned. After cleaning, waste liquid is discharged by pump 14. After cleaning the pit and preheating and softening the pit inner wall and surrounding road surface, the material in mixing tank 22 is evenly mixed by stirring shaft 24 and stirring rod 25, and maintained at the preset operating temperature by heating plate 212. Then, start the control switch of pump 14 on the operation panel. After pump 14 starts, it draws material from mixing tank 22 through pump pipe 141. The material inside is stably conveyed to the pouring head 143 via the conveying pipe 142. The operator holds the conveying pipe 142 and, through the adjustability of the corrugated flexible telescopic pipe, aligns the pouring head 143 with the pit, gradually and evenly pouring the material along the inner wall of the pit to the center, ensuring that the material fills the pit and is slightly higher than the original road surface by 1-2mm. After compaction, the material in the pit is immediately compacted in layers using the matching compaction tool until the material is flush with the original road surface and dense without gaps, completing the pit repair. The positioning ring 15 is used to limit and fix the hot air pipe 131 and the conveying pipe 142 in the stored state to prevent the pipes from getting tangled. The protective cover 151 is used to provide full protection for the spray head 132 and the pouring head 143 when not in operation. The base plate 11 is an integral steel structure.This device provides stable installation support for the hot air blower 13, the material pump 14, the maintenance box 16, and the protective box 21. The maintenance box 16 has internal compartments for storing maintenance tools, spare parts, and auxiliary consumables.
