Description

Technical Field

[0001] This invention relates to the field of roadbed maintenance technology, and in particular to a roadbed repair device for road construction. Background Technology

[0002] The roadbed is the foundation of a track or road surface, and it is a geotechnical structure formed by excavation or filling. The main function of the roadbed is to provide the necessary conditions for track or road surface laying and train or vehicle operation, and to bear the static and dynamic loads of the track, locomotives, rolling stock, road surface, and traffic loads. It also transfers the loads to the depths of the foundation and diffuses them thereafter. In longitudinal section, the roadbed must maintain the required height. In horizontal section, the roadbed connects with bridges and tunnels to form a complete and continuous route. After prolonged use and due to structural issues, the roadbed is prone to damage, necessitating maintenance to ensure its continued normal use.

[0003] Existing roadbed repair equipment relies on manual multi-step operations, which are complex and difficult to control in terms of precision. In addition, the original potholes need to be pre-treated before repair, and the damaged edges of the original potholes need to be cut off during the pre-treatment process. In general, the cutting is done to the deepest part of the original pothole, which will increase the volume of the original pothole and increase the amount of new material to be filled. Furthermore, the middle part of the original pothole is prone to sinking again after repair, requiring repeated repairs. Summary of the Invention

[0029] like Figures 1-8 As shown in the embodiment of the present invention, a roadbed repair device for road construction is suitable for repairing original potholes on roads. Specifically, the roadbed repair device for road construction includes a vehicle body 100, a detection mechanism, a grinding mechanism, a mixing mechanism, and a filling mechanism. The vehicle body 100 is movably arranged. The detection mechanism, grinding mechanism, mixing mechanism, and filling mechanism are all arranged on the vehicle body 100. The detection mechanism is used to detect the original pothole and obtain the shape and size data of the original pothole. The grinding mechanism grinds the first area of ​​the edge of the original pothole to a preset depth according to the data obtained by the detection mechanism. The first area is the minimum grinding area determined according to the shape of the original pothole and is obtained by the operator through measurement. The preset depth is the amount of waste material to be ground after the detection mechanism detects the original pothole and fills the original pothole. The mixing mechanism is used to fill the original pothole with the ground waste material until the original pothole is filled to be flush with the lower end surface of the first area, forming a new pre-repaired pothole. The filling mechanism is used to transport new material to the pre-repaired pothole and the first area.

[0030] Specifically, the vehicle body 100 is equipped with a control box 105. The control box 105 is used to convert the signals measured by the detection mechanism into data, and then control the operation of the grinding mechanism, mixing mechanism and filling mechanism. The detection mechanism measures the shape and size of the original road pit and converts it into data to control the grinding mechanism to grind the first area to a preset depth, achieving precise control and avoiding excessive waste material from grinding, which would cause waste. At the same time, it also reduces the amount of new material to be filled, saving new material. The mixing mechanism is set up to mix the waste material after grinding and fill it into the original road pit to form a pre-repaired road pit, further reducing the amount of new material to be filled. The filling mechanism fills the pre-repaired road pit.

[0031] Specifically, a partition 106 is provided in the vertical direction of the vehicle body 100. The partition 106 is used to separate the various mechanisms and can strengthen the vehicle body 100.

[0032] In this embodiment, the filling mechanism can adjust the material conveying end to a preset position according to the data obtained by the detection mechanism. The preset position is located in the pre-repaired road pit and directly above the bottom of the original road pit. The preset position is the lowest position in the original road pit detected by the detection mechanism. When the filling mechanism is located here, the new material will be piled up in a hill shape here. In the subsequent rolling process, it is used to increase the density of the new material and waste material filled here.

[0033] In this embodiment, the vehicle body 100 moves along a first direction; the grinding mechanism includes a first fixed plate 120, a second electric telescopic rod 121, a movable plate 125, a dual-axis motor 123, two brackets 127, and two grinding wheels 122.

The first gear 124 and the second gear 126 mesh, and the first gear 124 and the second gear 126 can slide relative to each other in the second direction. When grinding the original road pit, the operator determines the first area based on the shape and size of the original road pit, and then pulls the bracket 127 to move in the second direction, so that the grinding wheel 122 can grind the first area. The second electric telescopic rod 121 controls the grinding depth of the grinding wheel 122 in the first area through the detection data provided by the detection mechanism, so as to avoid excessive grinding, which would cause equipment wear and energy consumption.

[0035] In another embodiment, the two output shafts of the dual-axis motor 123 are provided with teeth, and the two grinding wheels 122 are provided with grooves at one end near the dual-axis motor 123. The grooves are provided with internal teeth, and the output shafts of the dual-axis motor 123 are slidably disposed in the grooves along the second direction, and the output shafts of the dual-axis motor 123 mesh with the grooves.

[0036] In this embodiment, the mixing mechanism includes a third fixed plate 163, a collection component, a spraying component, and a stirring component. The third fixed plate 163 is mounted on the vehicle body 100, and the collection component, spraying component, and stirring component are all mounted on the third fixed plate 163. The collection component is used to collect the polished waste material into the original road pit, so that the waste material partially fills the original road pit and makes the bottom depth of the filled pit flush with the preset depth after polishing, forming a pre-repaired road pit. The spraying component is used to spray adhesive into the original road pit, which can increase the adhesion between the new material and the waste material in the original road pit. The stirring component is used to stir and mix the waste material sprayed with adhesive in the original road pit, which can improve the mixing uniformity of the waste material and the adhesive and improve the strength between the waste materials.

[0037] The collection components are provided in two sets, located on both sides of the stirring component in the second direction. Each collection component is correspondingly set with a grinding wheel 122 in the first direction, and the maximum distance between the two collection components in the second direction is equal to the distance between the grinding wheels 122 in the second direction. When the grinding wheel 122 changes the grinding range, the collection group can change the range of waste collection accordingly.

[0038] Specifically, each collection assembly includes a second sliding shell 172, a fifth electric telescopic rod 174, a fifth motor 171, and a material-pushing plate 173. The second sliding shell 172 is disposed on the lower surface of the third fixed plate 163.

[0039] The liquid spraying assembly includes a liquid tank 160, a first liquid pipe 161, a second liquid pipe 162, a first limiting plate 170, and a second limiting plate 168. The liquid tank 160 is mounted on a third fixing plate 163. One end of both the first liquid pipe 161 and the second liquid pipe 162 is connected to the liquid tank 160, and the other end of both the first liquid pipe 161 and the second liquid pipe 162 is provided with a liquid outlet. The first limiting plate 170 is mounted on the third fixing plate 163 and connected to the first liquid pipe 161 for fixing the first liquid pipe 161. The second limiting plate 170 is mounted on the third fixing plate 163 and connected to the first liquid pipe 161 for fixing the first liquid pipe 161.

The second limiting plate 168 is connected to the second liquid pipe 162 and is used to fix the second liquid pipe 162. In the forward direction of the vehicle body 100, the first liquid pipe 161 is located in front of the second liquid pipe 162. The first liquid pipe 161 is used to spray adhesive on the original road pothole to improve the adhesion between the waste and the original road pothole. The second liquid pipe 162 is used to spray the waste generated after the second area is polished.

[0040] The stirring assembly includes a first sliding shell 165, a third motor 166, a second drive wheel 164, a fourth electric telescopic rod 167, a fourth motor 169, and a stirring blade 175. The first sliding shell 165 is installed on the lower surface of the third fixed plate 163 and is located between two second sliding shells 172. The third motor 166 is vertically disposed in the first sliding shell 165 and slides in the first sliding shell 165 in a second direction. The second drive wheel 164 is installed on the output shaft of the first motor 163 and is in contact with the inner surface of the first sliding shell 165. When the third motor 166 drives the first motor 167, the third motor 168, the fourth motor 169, and the stirring blade 175, the stirring blade 175, the stirring blade 166, the third motor 169, the fourth motor 160, the fourth motor 161, and the stirring blade 175. When the second drive wheel 164 rotates, friction is generated between the second drive wheel 164 and the first sliding shell 165, which can drive the third motor 166 to slide inside the first sliding shell 165; the fourth electric telescopic rod 167 passes through the first sliding shell 165 and is installed on the third motor 166, and the fourth electric telescopic rod 167 can extend in the vertical direction.

[0041] In another embodiment, the collection assembly may also include an electric push rod and a shovel. The electric push rod is vertically mounted on the third fixed plate 163 and slides on the third fixed plate 163 in the second direction. The shovel is mounted on the bottom end of the electric push rod and contacts the lower end surface of the grinding wheel 122 after grinding. In the direction in which the vehicle body 100 moves forward, the front end of the shovel is always in contact with the vertical surface of the original road pit to guide the waste.

The length of the scraper 101 is adapted to the width of the first region in the second direction, and it can slide on the lower end surface of the first region.

[0044] Specifically, the vehicle body 100 is also equipped with a first electric telescopic rod 102 and a baffle 107. The first electric telescopic rod 102 is vertically installed in the vehicle body 100, and one end of the first electric telescopic rod 102 is engaged with the scraper 101. The first electric telescopic rod 102 can drive the scraper 101 to slide in the vertical direction. The baffle 107 is installed in the vehicle body 100, and the scraper 101 is disposed between the baffle 107 and the partition 106. The baffle 107 is used to support the scraper 101. When the width of the first area in the second direction changes, the second scraper 101 can be disassembled and replaced with a scraper 101 suitable for the current size of the first area. The scraper 101 can scrape the mixed waste material flat, so that the bottom of the pre-repaired road pit is flat.

[0045] In this embodiment, the filling mechanism includes a guide hopper 140, a bellows 141, a limiting frame 142, a second motor 143, and two limiting rods 144. The guide hopper 140 is mounted on the vehicle body 100. One end of the bellows 141 is the feeding end, and the other end is the discharging end. The feeding end of the bellows 141 is connected to the interior of the guide hopper 140, and the discharging end of the bellows 141 can slide along the second direction.

The two limiting rods 144 are mounted in the vehicle body 100 and extend along the second direction. The limiting frame 142 is located in the middle of the two limiting rods 144 and can slide along the limiting rods 144 in the second direction. The output end of the second motor 143 cooperates with the limiting rods 144 to drive the limiting frame 142 to slide on the limiting rods 144.

[0046] Specifically, when the discharge end moves to the filling position, the control box 105 controls the second motor 143 to rotate according to the data provided by the detection mechanism, and drives the limit frame 142 to move to the lowest position of the original road pit in the second direction, so that the new material is concentrated here, reducing the gap after rolling and increasing the hardness of the road surface after repair.

[0047] In this embodiment, the detection mechanism includes a second fixed plate 110, a laser scanner 111, a slide rail 115, a rotating plate 112, a first motor 113, and a first drive wheel 114.

[0048] Specifically, as the vehicle body 100 moves forward, the laser scanner 111 slides back and forth in the second direction, which can roughly detect the outline of the original pothole and determine the position of the bottom of the original pothole. The data is then transmitted to the control box 105, which controls the operation of the corresponding mechanism according to the distance the vehicle body 100 has traveled.

[0049] In this embodiment, a dust removal mechanism is also included, which is used to clean the original potholes.

[0050] Specifically, the dust removal mechanism is installed on the vehicle body 100, and the dust removal mechanism is located in front of the detection mechanism in the forward direction of the vehicle body 100. The dust removal mechanism includes a dust collection box 150, a fan 151, and a dust suction hood 152. The dust collection box 150 is installed on the vehicle body 100, the dust suction hood 152 is installed at the bottom of the dust collection box 150, and the fan 151 is installed in the dust collection box 150 to suck debris into the dust collection box 150 through the dust suction hood 152.

[0051] In this embodiment, a rolling mechanism is also included, which includes three pressure rollers 132. In the direction in which the vehicle body 100 moves forward, the three pressure rollers 132 rise sequentially in the vertical direction and are arranged in sequence.

[0052] Specifically, the rolling mechanism also includes a third telescopic rod 131 and a third limiting plate 130. The third telescopic rod 131 is vertically installed on the vehicle body 100, and the third limiting plate 130 is installed at the bottom end of the third telescopic rod 131. Three pressure rollers 132 are rotatably mounted on the third limiting plate 130, and the axes of the three pressure rollers 132 extend along the second direction. When the pressure rollers 132 roll the new material, they gradually increase the pressure on the new material and reduce the thrust of the pressure rollers 132 on the new material in the first direction, so that the filled new material is subjected to greater pressure in the vertical direction, which increases the density of the new material and the density of the waste material and extends the service life of the repaired road surface.

[0053] In this embodiment, the vehicle body 100 is provided with rollers 103 to facilitate the movement of the vehicle body 100, and the vehicle body 100 is equipped with handles 104 to facilitate the use of operators.

[0054] The working principle and method of a roadbed repair device for road construction provided in this embodiment are as follows:

[0055] When using the roadbed repair equipment for road construction, the operator first determines the first area of ​​the original pothole based on its surface shape. Then, one of the movable plates 125 is pushed, causing it to slide along the second direction on the first fixed plate 120. The movable plate 125 drives the grinding wheel 122 to move together, so that the grinding wheel 122 can grind the first area. As the grinding wheel 122 moves, it drives the first gear 124 to move. The first gear 124 and the second gear 126 slide relative to each other in the second direction. The position of the other grinding wheel 122 is adjusted in the same direction. Next, the fifth motor 171 is pushed, which drives the fifth electric telescopic rod 174 to move along the second direction in the second sliding shell 172. As the fifth electric telescopic rod 174 moves, it drives the second limiting plate 168 to move. The second limiting plate 168 drives the second liquid pipe 162 to move, changing the spraying position of the second liquid pipe 162.

[0056] Then, the operator can move the vehicle body 100 by pushing the handle 104, so that the dust suction hood 152 can remove dust from the first area. The operator continues to push the vehicle body 100 and starts the first motor 113 and laser scanner 111 via the control box 105. The first motor 113 drives the first drive wheel 114 to rotate in the slide rail 115. The first drive wheel 114 moves in the slide rail 115 through friction with the vertical surface of the slide rail 115. Simultaneously, the rotating plate 112 drives the laser scanner 111 to move on the second fixed plate 110, allowing the laser scanner 111 to detect the original potholes and collect the collected dust. The data is transmitted to the control box 105, which continues to push the vehicle body 100 and starts the dual-axis motor 123. The dual-axis motor 123 drives the first gear 124 to rotate through the second gear 126. The first gear 124 drives the grinding wheel 122 to rotate. When the grinding wheel 122 moves to the first area, the control box 105 controls the extension and retraction of the second electric telescopic rod 121 through the data transmitted back by the laser scanner 111. The extension and retraction of the second electric telescopic rod 121 determines the grinding depth of the grinding wheel 122, so that the waste generated after grinding can reach the height of the grinding rear end face after filling the original road pit in the area.

[0057] The vehicle body 100 continues to move forward. When the first liquid pipe 161 moves into the first area, the first liquid pipe 161 begins to spray adhesive. When the material-pushing plate 173 is fully inside the first area, the control box 105 controls the start of the fifth electric telescopic rod 174 and the fifth motor 171. The fifth electric telescopic rod 174 pushes the first motor 113 downward, so that the material-pushing plate 173 contacts the polished end face. The fifth motor 171 drives the material-pushing plate 173 to rotate, cleaning the polished waste material into the original road pit. Then, the second liquid pipe 162 is started to spray adhesive on the polished waste material and the end face. Simultaneously, the third motor 166, the fourth electric telescopic rod 167, and the fourth motor 169 are activated. The third motor 166 drives the second drive wheel 164 to rotate. The rotation of the second drive wheel 164 generates friction with the first sliding shell 165. Through friction, the third motor 166 slides in the first sliding shell 165 along the second direction and drives the fourth electric telescopic rod 167 to move. The fourth electric telescopic rod 167 extends, causing the mixing plate 175 to extend into the original road pit. The fourth motor 169 drives the mixing plate 175 to rotate and mix the waste material mixed with binder in the original road pit.

[0058] When the scraper 101 moves to the position of the first area, the control box 105 controls the first electric telescopic rod 102 to push the scraper 101 downward and flush with the polished end face, so as to scrape the mixed waste material and form a new pre-repaired road pit.

[0059] Next, the vehicle body 100 continues to move forward. When the corrugated pipe 141 moves above the first area, the new material in the guide hopper 140 is transported to the pre-repaired road pit through the corrugated pipe 141. The control box 105 controls the second motor 143 to start, so that the limit frame 142 drives the outlet end of the corrugated pipe 141 to move on the limit rod 144 to the lowest position of the original road pit, and accumulates most of the new material here.

[0060] When the pressure roller 132 passes through this point, the pressure roller 132 at the higher position first contacts the new material and pre-compresses it. Then, the pressure roller 132 at a slightly lower position rolls the pre-compressed new material to further compact the new material in the pre-repaired road pit. Finally, the roadbed repair is completed by the rolling of the pressure roller 132 at the lowest position.

[0061] As the vehicle body 100 moves forward, the control box 105 adjusts and controls each position based on the results detected by the laser scanner 111. The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combination of these technical features does not contradict each other, it should be considered within the scope of this specification.

[0062] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
