Description

Technical Field

[0001] The present invention relates to the technical field of road repair equipment, and more specifically, to a road repair device with a metering function. Background Art

[0002] Urban roads are generally wider than highways. To accommodate complex means of transportation, they are often divided into motor vehicle lanes, bus priority lanes, non-motor vehicle lanes, etc. During long-term use, cracks will occur on the roads, and these cracks need to be repaired using repair materials.

[0003] Existing road repair devices include a mobile vehicle body, a raw material tank assembly, a fan assembly, a control and analysis system, a display, and an execution structure arranged on the mobile vehicle body; during use, the raw material tank assembly pumps the raw materials to the execution structure, and then the injection operation of the raw materials into the road cracks is realized through the execution mechanism; however, this device design has the following drawbacks in the implementation process: it is not convenient for the staff to align the execution structure with the road cracks, which affects the progress of the repair work. Moreover, due to the tortuousness of the road cracks, the staff needs to continuously maintain the alignment of the execution structure with the road cracks, resulting in a large working intensity and being prone to omissions, which affects the repair efficiency and effect of the road cracks; it does not have a metering function, and the amount of raw materials output by the raw material tank assembly is controlled by manual operation, which may result in too much or too little raw material output, affecting the repair accuracy of the road cracks.

The detection component transmits the detected information to the control and analysis system, establishing a mathematical model to determine the amount of raw materials required for each crack segment. This ensures that an appropriate amount of material can be obtained at each repair point. Combined with the metering of the raw material amount by the discharging component, it can control the output frequency of the raw material tank component, avoiding material waste. Moreover, the buffer pipe component provides a stable buffer zone during the pumping process of the raw material tank component, reducing the unstable flow caused by fluctuations during the raw material transportation, making the output raw material amount more uniform, and achieving more precise repair.

[0061] 2. The present invention enhances the construction quality: The air pressure component can blow and clean the road cracks before repair, removing dust and impurities, ensuring a stronger bonding force between the new and old materials, improving the overall strength and durability of the repair area. Moreover, the guiding component can enter the crack with the robotic arm and contact the bottom of the crack, making adaptive adjustments according to the actual terrain of the crack, ensuring that the discharging component is at the optimal height, further enhancing the adhesion and overall strength of the repair material.

[0062] 3. The present invention improves the operation convenience: The entire device realizes automated operation through the control and analysis system, reduces the need for manual intervention, lowers the labor intensity, and simultaneously improves the work efficiency. Moreover, it integrates multiple functional modules (such as detection, cleaning, metering, leveling, etc.), achieving an integrated process from detection to repair in one device, simplifying the construction steps, and improving the overall operation efficiency.

[0063] 4. The present invention extends the service life of the device: A scraping component is provided on the slow material pipe assembly. Without affecting the normal material transportation, it can regularly clean the attached substances, prevent blockage problems caused by long-term use, extend the service life of the device, and also adds an anti-blocking design, effectively solving the blockage problem of the discharging component and ensuring the continuous and stable operation of the device.

[0074] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention. The present invention will be further described in conjunction with the drawings and embodiments:

[0075] Refer to the attached Figure 1 As shown, a road repair device with a metering function includes a mobile vehicle body 1, a raw material tank assembly 2, a fan assembly 3, a control and analysis system 4, a display 5, and an execution structure 6 provided on the mobile vehicle body 1; the above structures are all publicly known technical means in the road repair device in the prior art, and for this, this application will not elaborate too much. This application mainly improves the execution structure 6.

[0076] Therefore, specifically for the structure of the execution structure 6, refer to the attached Figure 2 to the attached Figure 4 As shown, the execution structure 6 includes:

[0077] A robot arm 61, which is arranged at the front end of the mobile vehicle body 1 and is electrically connected to the control and analysis system 4;

[0078] A slow material pipe assembly 62, which is communicated with the output end of the raw material tank assembly 2 and is connected to the execution end of the robot arm 61, so that the slow material pipe assembly 62 can receive the raw materials output by the raw material tank assembly 2, and the coordinate position can be changed;

[0079] The mounting bracket 63 is arranged on the side of the buffer pipe assembly 62;

[0080] The mounting shell 631 is arranged at the bottom of the buffer pipe assembly 62;

[0081] The detection component 64 is electrically connected to the control and analysis system 4 and arranged on the mounting bracket 63, so that the mobile vehicle body 1 moves along the path of the road crack obtained by the detection component 64 for tracing, the robotic arm 61 positions according to the three-dimensional contour of the road crack obtained by the detection component 64, and the detection component 64 feeds back the obtained road image to the display 5;

[0082] The wind pressure component 65 is connected to the output end of the fan component 3 and arranged on the mounting bracket 63 to blow air at the crack position to clean the dust and impurities at the crack position;

[0083] The discharging component 66 is electrically connected to the control and analysis system 4 and arranged in the mounting shell 631, and is communicated with the buffer pipe assembly 62 to measure the output amount of the raw material and control the output frequency of the raw material tank assembly 2;

[0084] The guiding component 67 is electrically connected to the control and analysis system 4 and arranged in the mounting shell 631, and has a pressure detection function, and extends into the road crack and moves along the crack position to detect the downward movement distance of the robotic arm 61 and determine the distance between the discharging component 66 and the bottom of the road crack, so as to improve the output effect of the discharging component 66 on the raw material;

[0085] The smoothing component 68 is arranged on the mounting shell 631 and covers the outside of the discharging component 66 and the guiding component 67, and can move upward when a thrust is applied to its bottom, and smooths the raw material output to the road crack through the discharging component 66 during the process of moving and contacting the road surface.

[0086] In the specific implementation process of this application, the steps and principles are as follows:

[0087] The device moves to the road crack, starts the device, and the detection component 64 scans the path of the road crack, so that the moving vehicle body 1 moves along the path of the road crack obtained by the detection component 64 for tracking; subsequently, the robotic arm 61 drives the discharging component 66 and the guiding component 67 to find the position according to the three-dimensional contour of the road crack obtained by the detection component 64, so that the guiding component 67 extends into the road crack and moves along the crack position; at the same time, the fan component 3 operates to make the air pressure component 65 blow air at the road crack position to clean the dust and impurities at the crack position; in addition, when the pressure value received by the guiding component 67 reaches the set value, the distance between the discharging component 66 and the bottom of the road crack is at a better raw material output distance (the better output distance can improve the uniformity, adhesion and the quality of the finally formed structure of the distribution in the road crack); furthermore, according to the three-dimensional contour of the road crack obtained by the detection component 64, the control and analysis system 4 establishes a mathematical model and obtains the actual output amount of the raw material (divide the road crack into several sections, measure and output the corresponding raw material amount for each section); at this time, the raw material tank component 2 operates to output the raw material to the buffer pipe component 62, and then the discharging component 66 measures the output raw material amount and outputs it into the road crack; at the same time, the smoothing component 68 smooths the raw material output into the road crack during the process of moving and contacting with the road surface, so as to realize the automatic repair operation of the road crack.

[0088] In the above solution, specifically for the structure of the buffer pipe component 62, refer to the attached Figure 3 As shown, the buffer pipe component 62 includes:

[0089] The pipe body 621, which has a circular structure and is open at the bottom, and is connected to the execution end of the robotic arm 61;

[0090] The docking pipe 622, which is arranged at the top of the pipe body 621, and its top end extends outside the pipe body 621, and its bottom end extends inside the pipe body 621;

[0091] The rotary joint one 623, which is arranged at the top end of the docking pipe 622 and is connected to the output end of the raw material tank component 2.

[0092] During the implementation of this solution, the raw materials output by the raw material tank assembly 2 will be pre-stored in the pipe body 621, and then enter the discharging assembly 66 under pressure through the continuous output of the raw material pipe assembly. In this way, a stable buffer zone can be provided during the pumping process of the raw material tank assembly 2, reducing the unstable flow caused by fluctuations (such as pulsation effects) during the raw material transportation, making the output raw material quantity more uniform, which helps to achieve more precise repair. Moreover, when there is a short pause or flow change during the pumping process of the raw material tank assembly 2, the raw materials pre-stored in the pipe body 621 can continue to be supplied to prevent the interruption of the output process, thereby maintaining continuity and consistency. Combined with the metering of the raw material quantity by the discharging assembly 66, the specific dosage of each output can be more precisely controlled to ensure that each repair point receives an appropriate amount of raw materials.

[0093] In the above solution, specifically for the structure of the detection assembly 64, referring to the attached Figure 2 As shown, the detection assembly 64 includes:

[0094] A camera 641, which is arranged on the mounting frame 63 and electrically connected to the control and analysis system 4 to capture road cracks, identify the position and shape of the trajectory line, and enable the mobile vehicle body 1 to perform tracking movement along the acquired road crack path;

[0095] An image scanner 642, which is arranged on the mounting frame 63 and electrically connected to the control and analysis system 4 to scan the three-dimensional contour of the road crack, and enable the robotic arm 61 to find the position according to the three-dimensional contour of the road crack acquired by the detection assembly 64;

[0096] During the implementation of this solution, the camera 641 and the image scanner 642 are used in cooperation to realize the scanning of the road crack path and three-dimensional contour data. Subsequently, the control and analysis system 4 analyzes and integrates the collected data, establishes a mapping model between the crack size and the raw material demand, and obtains the actual output quantity of the raw materials, so as to ensure the data detection operation during the automatic repair of the road crack by the device.

[0097] In the above solution, specifically for the structure of the wind pressure assembly 65, referring to the attached Figure 2 As shown, the wind pressure assembly 65 includes:

[0098] A branch pipe 651, which is arranged on the mounting frame 63;

[0099] A rotary joint II 652, which is arranged at the top of the branch pipe 651 and connected to the output end of the fan assembly 3;

[0100] An installation pipe 653, which is connected to the bottom end of the branch pipe 651 and is horizontally arranged;

[0101] There are multiple air nozzles 654, which are arranged along the length direction of the installation pipe 653, and the air outlet direction is inclined downward;

[0102] During the implementation of this solution, as the robotic arm 61 moves and locates the position of the road crack, the air nozzle 654 generates air pressure at its position to clean the dust and impurities in the road crack. Through cleaning, it can ensure that the raw material fits tightly with the original road surface, forming a stronger bonding force.

[0103] In the above solution, specifically for the structure of the discharging component 66, refer to the attached Figure 4 As shown, the discharging component 66 includes:

[0104] The discharging nozzle 661 is arranged inside the mounting shell 631 and its top is communicated with the bottom of the pipe body 621. The upper part of the discharging nozzle 661 is conical and the lower part is circular;

[0105] The flowmeter 662 is arranged on the discharging nozzle 661 and is electrically connected to the control and analysis system 4;

[0106] During the implementation of this solution, the raw material is discharged through part of the discharging nozzle 661. During the discharging process, the flowmeter 662 measures the amount of raw material at all times. When the required amount of raw material for this section of the road crack is reached, the output frequency of the raw material tank component 2 changes or stops outputting raw material. Due to the structural design of the discharging nozzle 661, it helps to gradually guide the raw material from a larger inlet to a smaller outlet, enabling the raw material to flow more concentratedly towards the outlet of the discharging nozzle 661, reducing accumulation, optimizing the flow characteristics of the raw material, and thus improving the discharging accuracy of the raw material.

[0107] In the above solution, specifically for the structure of the guiding component 67, refer to the attached Figure 4 As shown, the guiding component 67 includes:

[0108] The guiding column 671 is vertically arranged inside the mounting shell 631;

[0109] The limiting plate 672 is arranged at the bottom of the guiding column 671;

[0110] The reciprocating spring 673 is sleeved outside the guiding column 671;

[0111] The moving seat 674 is slidably arranged outside the guiding column 671 and is located between the limiting plate 672 and the reciprocating spring 673;

[0112] The vertical rod 675 is arranged on the moving seat 674;

[0113] The ball 676 is arranged at the bottom of the vertical rod 675;

[0114] The pressing seat 677 is arranged at the top of the vertical rod 675;

[0115] The pressure sensor 678 is arranged inside the mounting shell 631 and is correspondingly arranged with the pressing seat 677, and is electrically connected to the control and analysis system 4;

[0116] During the implementation of the solution, the ball 676 enters the road crack along with the operation of the robotic arm 61 and contacts the bottom of the road crack. Due to the properties of the ball 676, the restriction during movement is small, enabling it to adapt to the terrain of the road crack. During the movement, the reciprocating spring 673 can reduce a certain impact force. As the reciprocating spring 673 is compressed, the pressure seat 677 continuously moves upward until it contacts the pressure sensor 678. When the pressure sensor 678 reaches the set value, at this time, it can be determined that the position of the discharge nozzle 661 reaches the optimal discharge height, and the discharge nozzle 661 starts to discharge materials. Through the setting of the guiding component 67, the discharge nozzle 661 can be given an optimal discharge height (if the discharge nozzle 661 is too high from the ground, the raw materials may disperse or stratify during the falling process, resulting in uneven material distribution. A higher discharge height may cause separation of large particles and fine particles, affecting the overall strength and durability of the raw materials; if the discharge nozzle 661 is too low from the ground, it may cause accumulation of raw materials, forming a phenomenon of uneven local thickness, and even the situation where the raw materials cannot completely cover the area to be repaired), ensuring that the construction process is always in the optimal state.

[0117] In the above solution, specifically for the structure of the flattening component 68, refer to the attached Figure 3 As shown, the flattening component 68 includes:

[0118] A socket 681, arranged outside the mounting shell 631;

[0119] A guide rod 682, slidably arranged in the socket 681;

[0120] A limit seat 683, fixedly arranged at the top of the guide rod 682 and located above the socket 681;

[0121] A housing cover 684, connected to the bottom of the guide rod 682 and covering the outside of the mounting shell 631;

[0122] A flattening plate 685, arranged at the bottom of the housing cover 684 and used to contact the road surface;

[0123] During the implementation of the solution, the flattening plate 685 can move downward along with the operation of the robotic arm 61 and contact the road surface. Due to its design of being movable up and down, it can rebound appropriately when impacted by the uneven road surface, avoiding damage to the device and the road surface caused by rigid collision, reducing the risk of damage caused by impact, and can be adaptively adjusted according to the actual undulation of the road surface to ensure that it always closely fits the road surface, improving the consistency and reliability of the flattening effect. And because the flattening plate 685 covers the outside of the raw materials in the road crack, it can prevent the raw materials from overflowing or forming irregular edges, improving the overall aesthetics and flatness of the repaired area, and contributing to the subsequent maintenance work.

[0124] In the above solution, considering that during the use of the pipe body 621, there will be adhesion of raw materials on its inner wall. Therefore, from this perspective, referring to the attached Figure 5 to the attached Figure 7 As shown, a scraping component 69 for scraping the inner wall of the pipe body 621 is provided on the pipe body 621. Specifically, the scraping component 69 includes:

[0125] A moving rod 691, vertically slidably arranged on the pipe body 621;

[0126] A scraping plate 692, slidably arranged inside the pipe body 621 and having an opening in the middle, and the butt joint pipe 622 is inserted into the opening of the scraping plate 692 in the initial state;

[0127] A pressing handle 693, connected to the top end of the moving rod 691;

[0128] A return spring 694, sleeved outside the moving rod 691 and located between the pipe body 621 and the pressing handle 693;

[0129] During the implementation of the solution, when the scraping operation is not carried out, the opening of the scraping plate 692 is docked with the butt joint pipe 622. At this time, the scraping plate 692 is located at the top inside the pipe body 621, which does not affect the normal raw material transportation, and the raw material transportation does not contact the scraping plate 692 either. At this time, the return spring 694 is in a natural stretching state, the pressing handle 693 is located at a higher position, and the entire scraping component 69 is in a standby state; when it is necessary to clean the inner wall of the pipe body 621, press the pressing handle 693 downward, driving the moving rod 691 to move downward. As the moving rod 691 moves downward, the scraping plate 692 connected to its bottom also starts to slide down along the inner wall of the pipe body 621 to scrape the raw materials attached to the inner wall of the pipe body 621; after the scraping operation is completed, release the pressure on the pressing handle 693, and the resilience provided by the return spring 694 will push the moving rod 691 upward to make the scraping plate 692 return to the initial position, which has better reliability and convenience.

[0130] In addition, considering that there is a blockage problem with the discharge nozzle 661 during use, for this reason, referring to the attached Figure 8 and the attached Figure 9 As shown, the scraping component 69 further includes:

[0131] A circular ring seat 695, arranged in the opening of the scraping plate 692;

[0132] A rotating roller 696, arranged at the bottom of the circular ring seat 695;

[0133] A retaining piece 697, rotatably connected to the rotating roller 696;

[0134] A torsion spring 698, sleeved on the rotating roller 696 and connected to the retaining piece 697 to make the retaining piece 697 have an upward resilience;

[0135] During the implementation of the solution, when the scraping operation is not carried out, the opening of the scraper 692 is docked with the docking pipe 622. At this time, the baffle 697 is pushed open by the docking pipe 622, which does not affect the normal raw material transportation. When it is necessary to clean the inner wall of the pipe body 621, press down the pressing handle 693. When the scraper 692 is separated from the docking pipe 622, at this time, the baffle 697 is subjected to a resilience force to block the opening of the scraper 692 and form a complete circular plate structure with the scraper 692. When the pressing handle is continuously pressed, the circular plate structure applies pressure to the inside of the pipe body 621. As the circular plate structure continues to advance, the pressure inside the pipe body 621 continuously increases. The increased pressure exceeds the resistance caused by the raw materials to the discharge nozzle 661, so that the blocked raw materials are pushed away, improving the subsequent use effect.
