Description

Technical Field

[0001] The invention belongs to the technical field of highway maintenance equipment, and in particular relates to a highway asphalt gravel synchronous sealing robot. Background Art

[0002] The traditional sealing process is usually carried out in steps, first spraying asphalt, then spreading aggregate. Due to the interval between the two applications, the asphalt may cool too quickly, resulting in poor bonding between aggregate and asphalt. The emergence of synchronous chip seal vehicles has achieved the simultaneous asphalt spraying and aggregate spreading, greatly shortening the reaction time between the two.

[0003] With the continuous expansion of highway construction and the increasing quality requirements, intelligent construction has become a trend in the development of the industry. In this context, the introduction of robot technology into the field of highway asphalt gravel synchronous sealing construction is an inevitable choice. Intelligent robots can automatically complete complex construction tasks through pre-programming or real-time sensor feedback, thereby improving construction efficiency and quality. For example, using advanced sensor technology, robots can sense the flatness, width and other information of the road surface in real time, and automatically adjust the parameters of asphalt spraying and gravel spreading based on this information to achieve precise construction.

[0004] The existing Chinese patent with publication number CN118087335B discloses an asphalt gravel synchronous sealing vehicle, including a tractor, an asphalt folding and spreading mechanism, and a gravel evenly spreading mechanism. The asphalt folding and spreading mechanism is arranged at the top of the tractor, the gravel evenly spreading mechanism is arranged at the top of the tractor, the asphalt folding and spreading mechanism includes an asphalt transmission mechanism and a spreading adjustment mechanism, and the gravel evenly spreading mechanism includes a gravel transmission mechanism, an equalizing mechanism, and an adaptive adjustment mechanism. The invention designs an equalizing mechanism, which drives two equalizing plug shafts to slide in the slot toward the equalizing main axis direction through the action of the L-shaped telescopic rod, and utilizes the uniform force characteristics of the equalizing spring to make the equalizing slider evenly distributed between the two L-shaped telescopic rods, so as to adapt to different widths of road surfaces, solve the problem of missing or over-paving of gravel due to the variable road width in traditional technology, and greatly improve the applicability and resource utilization efficiency of the invention.

[0005] However, in the process of spraying asphalt onto the road surface through an asphalt nozzle in the above-mentioned patent, the fixed-angle spraying may cause insufficient asphalt spraying at the edge part or excessive concentration in the middle part. The nozzles of the spraying equipment are usually arranged in a certain straight line and the angle is fixed to point to the center of the road surface. For the edge part of the road surface, especially near the shoulder, the asphalt may not be effectively sprayed; this uneven edge coverage may also cause the bonding effect between the crushed stone and the asphalt to deteriorate; due to insufficient asphalt at the edge, the crushed stone cannot obtain enough adhesive after spreading, and is prone to falling off, which reduces the anti-skid performance and durability of the sealing layer. Summary of the invention

[0008] The present invention drives the spray nozzle to swing left and right through the swing shaft, so that the asphalt can be distributed more evenly in the width direction of the road, so that the asphalt and the crushed stone are better combined, and the anti-skid performance and durability of the sealing layer are improved.

[0009] Furthermore, a conveying auger is horizontally arranged in the gravel placement bin, a conveying motor transmission-connected to the conveying auger is arranged on the side wall of the gravel placement bin, and an inclined conveying channel extending into the installation frame is arranged on the side wall of the gravel placement bin.

[0012] Furthermore, the spraying moving mechanism includes a moving motor, a moving gear and two moving tooth plates. The moving motor is located in the installation frame. The moving gear is connected to the main shaft of the moving motor. The two moving tooth plates are symmetrically slidably connected to the bottom position of the installation frame. The moving gear is meshed with the two moving tooth plates.

[0013] Furthermore, two spraying swing mechanisms are provided, and the two spraying swing mechanisms are respectively arranged at the bottom positions of two movable tooth plates.

[0014] Furthermore, each of the spray swing mechanisms includes a mounting frame, a swing motor, a swing plate, a swing shaft and two support plates, the two support plates are symmetrically arranged at the two ends of the bottom of the moving tooth plate, the two ends of the swing shaft are respectively rotatably connected with the two support plates, the mounting frame is located in the middle position of the bottom of the moving tooth plate, the swing plate is connected to the main shaft of the swing motor, the swing shaft is provided with two symmetrically fixed connecting plates, a sliding rod is provided between the two connecting plates, the sliding rod is provided with a sliding sleeve, the sleeve is provided with a sliding column, and the sliding column is slidably matched with the swing plate.

[0016] At least one of the above technical solutions adopted in the embodiments of the present invention can achieve the following beneficial effects:

[0017] First, in the process of spraying asphalt of the present invention, the swing motor drives the swing plate to rotate, thereby driving the sliding column to slide on the swing plate, and the sliding of the sliding column drives the sleeve to slide left and right on the sliding rod, thereby driving the position of the two connecting plates to swing, so that the swing shaft swings on the two support plates. In the process of spraying asphalt, the swing shaft will drive the position of the spray nozzle to swing left and right, and the swing shaft drives the spray nozzle to swing left and right, which can make the asphalt more evenly distributed in the width direction of the road; when the spray nozzle swings left and right, the asphalt can cover a wider area and contact the gravel at a more suitable angle and thickness, just like providing a uniform and complete layer of glue (asphalt) to the jigsaw pieces (gravel), so that the gravel can be more easily embedded in the asphalt to form a tight embedded structure. This good bonding effect can enhance the shear strength and stability of the seal layer, reduce the risk of gravel falling off during subsequent use, and thus extend the service life of the highway asphalt gravel synchronous seal layer; when the spray nozzle swings, the asphalt can be sprayed onto the base surface at different angles and positions, which helps to enhance the adhesion between the asphalt and the base layer, and improves the anti-skid performance and durability of the seal layer.

[0018] Secondly, the mobile motor of the present invention drives the mobile gear to rotate, and the rotation of the mobile gear will drive the two mobile tooth plates to move closer to or farther from each other at the bottom of the installation frame, and the movement of the two mobile tooth plates will drive the positions of several spray nozzles to move back and forth in the horizontal direction. In the process of spraying asphalt, first, the spraying distance position can be adjusted according to the width of the road surface, and the moving distance of the two mobile tooth plates on the installation frame can be controlled. According to the width of the road surface, the asphalt can be sprayed comprehensively. Second, in the process of moving back and forth, the asphalt can be distributed more evenly in the spraying area. The reciprocating motion of the mobile tooth plate causes the position of the spray nozzle to change continuously, just like holding the nozzle and moving it regularly on a plane. Whether in the width direction or the length direction of the road, the spraying thickness of the asphalt can be made more uniform, which is very important for ensuring the quality of the road asphalt layer, and can effectively prevent the early damage of the road surface due to uneven asphalt thickness, such as potholes and cracks.

DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the specific embodiments of the present invention and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0031] The following describes in detail a technical solution of a highway asphalt gravel synchronous sealing robot according to various embodiments of the present invention in conjunction with the accompanying drawings.

[0032] Reference Figures 1 to 8 As shown, an embodiment of the present invention provides a highway asphalt gravel synchronous sealing robot, including a robot body 1, an asphalt placing bin 11 and a gravel placing bin 12 are provided at the rear of the robot body 1, and a mounting frame 13 is also provided at the rear of the robot body 1, a gravel distribution mechanism 2 for discharging gravel is provided in the mounting frame 13, and the gravel distribution mechanism 2 is rotatably connected to a position below the mounting frame 13, and a spraying moving mechanism 3 and a spraying swinging mechanism 4 are also provided on the mounting frame 13, the spraying moving mechanism 3 is arranged in the mounting frame 13 and the spraying moving mechanism 3 and the mounting frame 13 are slidably matched, the spraying swinging mechanism 4 is located on the spraying moving mechanism 3, a spraying member 5 connected to the asphalt placing bin 11 is provided on the spraying swinging mechanism 4, and a protective cover 6 is provided on the top of the mounting frame 13.

[0033] Specifically, refer to Figure 3 and Figure 4As shown, a conveying auger 121 is horizontally arranged in the crushed stone placement bin 12, a conveying motor 122 drivingly connected to the conveying auger 121 is arranged on the side wall of the crushed stone placement bin 12, and an inclined conveying channel 123 extending into the installation frame 13 is arranged on the side wall of the crushed stone placement bin 12; the inclined conveying channel 123 is a structure that is small at the top and large at the bottom, and a plurality of discharge frames 124 arranged at equal intervals are arranged on the installation frame 13, and the plurality of discharge frames 124 are connected to the inclined conveying channel 123;

[0034] When in use, the gravel is located in the gravel placement bin 12, and then the conveying motor 122 works to drive the conveying auger 121 to rotate in the gravel placement bin 12, thereby discharging the gravel from the gravel placement bin 12 to the outside into the inclined conveying channel 123, and the inclined conveying channel 123 evenly discharges the gravel into several discharge frames 124, thereby achieving uniform discharge of the gravel.

[0035] Specifically, refer to Figure 5 As shown, the gravel distribution mechanism 2 includes a driving motor 21, a driving shaft 22 and a plurality of distribution parts equidistantly arranged in a discharge frame 124, the driving shaft 22 passes through the plurality of discharge frames 124 and is rotatably connected to the plurality of discharge frames 124, the driving motor 21 is located on the side wall of the mounting frame 13 and is transmission-connected to the driving shaft 22, and the distribution parts include four distribution plates 23 equidistantly arranged on the driving shaft 22.

[0036] When the gravel falls into the discharge frame 124, the drive motor 21 starts to drive the drive shaft 22 to rotate, thereby driving the distribution plates 23 to rotate in the discharge frames 124, so that the gravel can be more evenly distributed at the outlet of the discharge frame 124. Because the distribution plates 23 can send the gravel in different directions during the rotation process, it can avoid the gravel being concentrated in a certain area of ​​the discharge frame 124. For example, for the spreading of gravel in the width direction of the road, uniform feeding can ensure that every square meter of the road surface can be covered with an appropriate amount of gravel, making the quality of the sealing layer more stable. Without this uniform feeding method, some parts of the road surface may have too much gravel, increasing the roughness of the road surface and affecting driving comfort; while some parts of the road surface may have too little gravel, which will reduce the waterproof and wear-resistant properties of the sealing layer;

[0037] The rotating distribution plate 23 can accurately control the feeding speed of the crushed stones according to the spraying speed and flow rate of the asphalt. When the asphalt spraying speed is fast, the rotation speed of the drive shaft 22 can be appropriately increased to allow more crushed stones to fall; conversely, when the asphalt spraying speed slows down, the amount of crushed stones fed can be adjusted accordingly. This synchronization helps to form a complete and well-bonded sealing structure. For example, during the construction process, if the crushed stones are fed too slowly, the asphalt may solidify first, resulting in the crushed stones not being firmly bonded; and if the crushed stones are fed too quickly, some of the crushed stones will not be well combined with the asphalt. These situations can be effectively avoided through the drive shaft 22 and the distribution plate 23.

[0038] During the feeding process of gravel, segregation is prone to occur, that is, gravel of different particle sizes is layered. The rotation of the distribution plate 23 can continuously stir and mix the gravel. When the drive shaft 22 drives the distribution plate 23 to rotate, the gravel of various particle sizes can be better mixed together under the stirring of the distribution plate 23. Just like in a mixing container, objects of different sizes can avoid stratification caused by natural accumulation through stirring. For asphalt gravel synchronous sealing, preventing gravel segregation can ensure the consistency of the sealing material performance, because gravel of different particle sizes plays a specific role in the sealing structure, and evenly mixed gravel can provide better embedding effect and bearing capacity.

[0039] Specifically, refer to Figure 7 As shown, the spraying moving mechanism 3 includes a moving motor 31, a moving gear 32 and two moving tooth plates 33. The moving motor 31 is located in the installation frame 13. The moving gear 32 is connected to the main shaft of the moving motor 31. The two moving tooth plates 33 are symmetrically slidably connected at the bottom position of the installation frame 13. The moving gear 32 is meshed with the two moving tooth plates 33.

[0040] The mobile motor 31 drives the mobile gear 32 to rotate, and the rotation of the mobile gear 32 will drive the two mobile tooth plates 33 to move closer to or farther from each other at the bottom of the installation frame 13, and the movement of the two mobile tooth plates 33 will drive the positions of the spray nozzles 54 to move back and forth in the horizontal direction. In the process of spraying asphalt, first, the spraying distance position can be adjusted according to the width of the road surface, and the moving distance of the two mobile tooth plates 33 on the installation frame 13 can be controlled. According to the width of the road surface, the asphalt can be sprayed comprehensively. Second, in the process of moving back and forth, the asphalt can be distributed more evenly in the spraying area. The reciprocating motion of the mobile tooth plate 33 makes the position of the spray nozzle constantly change, just like holding a spray head and moving it regularly on a plane. Whether in the width direction or the length direction of the road, the spraying thickness of the asphalt can be made more uniform, which is very important for ensuring the quality of the road asphalt layer, and can effectively prevent the early damage of the road surface due to uneven asphalt thickness, such as potholes and cracks.

[0041] Specifically, refer to Figure 8 As shown, the spraying swing mechanism 4 is constructed with two, and the two spraying swing mechanisms 4 are respectively arranged at the bottom position of the two moving tooth plates 33; each of the spraying swing mechanisms 4 includes a mounting frame 40, a swing motor 41, a swing plate 42, a swing shaft 43 and two support plates 44, and the two support plates 44 are symmetrically arranged at the two ends of the bottom of the moving tooth plate 33, and the two ends of the swing shaft 43 are respectively rotatably connected with the two support plates 44, and the mounting frame 40 is located at the middle position of the bottom of the moving tooth plate 33, and the swing plate 42 is connected to the main shaft of the swing motor 41, and the swing shaft 43 is provided with two symmetrically fixedly connected connecting plates 45, and a sliding rod 46 is provided between the two connecting plates 45, and a sliding sleeve 47 is provided on the sliding rod 46, and a sliding column 48 is provided on the sleeve 47, and the sliding column 48 is slidably matched with the swing plate 42.

[0042] During the process of spraying asphalt, the swing motor 41 drives the swing plate 42 to rotate, thereby driving the sliding column 48 to slide on the swing plate 42. The sliding of the sliding column 48 drives the sleeve 47 to slide left and right on the sliding rod, thereby driving the positions of the two connecting plates 45 to swing, so that the swing shaft 43 swings on the two support plates 44. During the process of spraying asphalt, the swing shaft 43 will drive the position of the spray nozzle 54 to swing left and right. The swing shaft 43 drives the spray nozzle to swing left and right, which can make the asphalt more evenly distributed in the width direction of the road; when the spray nozzle swings left and right, the asphalt can cover a wider area and contact the gravel at a more suitable angle and thickness, just like providing a uniform and complete layer of glue (asphalt) to the jigsaw pieces (gravel), so that the gravel can be more easily embedded in the asphalt to form a tight embedded structure. This good bonding effect can enhance the shear strength and stability of the seal layer, reduce the risk of gravel falling off during subsequent use, and thus extend the service life of the highway asphalt gravel synchronous seal layer; when the spray nozzle swings, the asphalt can be sprayed onto the base surface at different angles and positions, which helps to enhance the adhesion between the asphalt and the base.

[0043] Specifically, there are two spraying parts 5, each of which includes a delivery pump 51, a delivery pipe 52, a connecting pipe 53, a plurality of spray nozzles 54 and a plurality of mounting seats 55. The plurality of mounting frames 13 are arranged at equal intervals at the bottom of the swing shaft 43, the plurality of spray nozzles 54 are respectively located on the plurality of mounting seats 55, the connecting pipe 53 is connected to the plurality of spray nozzles 54, the delivery pump 51 is located on the robot body 1 and next to the asphalt placement bin 11, one end of the delivery pipe 52 is connected to the asphalt placement bin 11 and to the delivery pump 51, and the other end of the delivery pipe 52 extends to be connected to the connecting pipe 53.

[0044] When spraying asphalt on the road surface, the delivery pump 51 extracts the asphalt in the asphalt storage bin 11 through the delivery pipe 52, and then delivers it to the connecting pipe 53. The connecting pipe 53 delivers the asphalt to a plurality of spray nozzles 54, and the plurality of spray nozzles 54 will spray the asphalt evenly outward onto the road surface.

[0045] The above description is only an embodiment of the present invention and is not intended to limit the present invention.
