Description

Technical Field

[0001] The invention relates to the field of municipal engineering equipment, in particular to a road surface leveling device for municipal construction. Background Art

[0002] Cement concrete pavement is widely used in municipal road construction because of its advantages such as high strength, good stability, beautiful appearance and long service life. However, the flatness of cement concrete pavement directly affects the quality of pavement use and driving comfort. Therefore, a leveling machine is needed to level the pavement during pavement laying to improve the flatness of the pavement.

[0003] The patent document with application number: CN216514988U discloses a road construction engineering leveling machine, which includes two sets of reinforcement frames, two sets of lifting components, two sets of rotating components and a leveling component.

The two sets of lifting components are correspondingly installed in the two sets of reinforcement frames, and the two sets of rotating components are matched and installed on the inner side of the lifting components.

[0004] The following deficiencies still exist in its actual application: most of the current leveling machines first level the road with a scraper, and then use the leveling roller to rotate to level the road surface. However, during the leveling process, excess material will be pushed to the front of the scraper. When too much material is accumulated, the concrete will move to both sides and overflow, resulting in material waste. At the same time, due to the uneven distribution of concrete on the road surface, there is less concrete in some areas, resulting in depressions. Therefore, during the leveling process, the depressed parts of the road surface need to be manually filled with material, which reduces the construction efficiency. Summary of the invention

DETAILED DESCRIPTION

[0026] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, Figures 1 to 8 The structure of a road surface leveling device for municipal construction according to an embodiment of the present invention is schematically shown. The present invention will be further described below in conjunction with a specific embodiment.

[0027] See also Figure 1-Figure 3 The present invention provides a road leveling device for municipal construction, which structure includes a fixed frame 1, slide rails 2 on both sides of the fixed frame 1, pulleys 3 rollingly connected to the slide rails 2 are arranged on both sides of the fixed frame 1, a plurality of vibrating rods 4 are arranged at the front end of the fixed frame 1, a leveling roller 5 is arranged at the tail end of the fixed frame 1, and also includes a recovery device 6 arranged at the fixed frame 1 and located behind the vibrating rod 4, a concrete hopper 7 is arranged at the top of the fixed frame 1, and a feeding mechanism 8 for conveying concrete from the recovery device 6 to the inside of the concrete hopper 7, a discharging port of the concrete hopper 7 is connected to a discharging mechanism 9 for filling road potholes, and a plurality of ultrasonic ranging sensors 10 arranged in sequence along the width of the road surface are also arranged at the bottom of the fixed frame 1.

[0028] When the current leveling machine is in use, the slide rails 2 are placed on both sides of the road surface, and the pulleys 3 on both sides of the fixed frame 1 are driven by the driving member to move horizontally along the slide rails 2. Therefore, the vibrating rods 4 at the front end of the fixed frame 1 vibrate the concrete for construction, and at the same time, the scraper scrapes the road surface flat, and then the motor drives the leveling roller 5 to rotate, so as to sweep the road surface flat. However, during the leveling process of the scraper, excess materials will be pushed to the front of the scraper. When too much concrete is accumulated, the concrete will move to both sides and overflow outward, resulting in material waste. At the same time, due to the uneven distribution of concrete on the road surface, there is less concrete in some areas, resulting in depressions. Therefore, during the leveling process, the depressed parts of the road surface need to be manually supplemented with materials, which reduces the construction efficiency. Therefore, a recovery device 6, a concrete hopper 7, a feeding mechanism 8, a discharging mechanism 9, and an ultrasonic ranging sensor 10 are provided. Therefore, when in use, after the scraper is leveled, the excess materials in front of the scraper are recovered by the recovery device 6, and the recovered materials are transported to the concrete hopper 7 by the feeding mechanism 8. The ultrasonic distance sensor 10 is electrically connected to the discharging mechanism 9, and all the ultrasonic distance sensors 10 are arranged on the same horizontal plane. At the same time, the probe is arranged toward the road surface. The distance between the ultrasonic distance sensor 10 and the horizontal plane of the road surface is set to a standard value. Therefore, after the scraper is leveled, as the fixed frame 1 is translated, the ultrasonic distance sensor 10 at the bottom of the fixed frame 1 detects the leveled road surface. When the distance detected exceeds the standard value, it is determined that there is a depression in the road surface, and then the material in the concrete hopper 7 is filled into the depressed part through the discharging mechanism 9. When the ultrasonic distance sensor 10 in the corresponding area detects the distance equal to the standard value, the discharging mechanism 9 stops filling, and the road surface is leveled again through the leveling roller 5. Therefore, the leveling machine can recycle excess material on the road surface when in use to avoid waste caused by overflow. At the same time, the recycled material is filled into the depressed part of the road surface. There is no need to manually fill the depressed part, which can effectively improve the efficiency of road leveling.

[0029] like Figure 2-4 As shown, specifically, the recovery device 6 includes a shovel plate 61 arranged on the fixed frame 1, and a conveying trough 62 is formed between the side of the shovel plate 61 close to the leveling roller 5 and the fixed frame 1, and baffles 63 are respectively provided at both ends of the shovel plate 61 and the conveying trough 62, and a conveying roller 64 in the conveying trough 62 is provided between the two baffles 63, and a continuous spiral blade 65 is provided on the outer side of the conveying roller 64, and the conveying trough 62 is provided with a connecting port 66 connected to the feeding mechanism 8, and the fixed frame 1 is also provided with a first driving motor 67 that drives the conveying roller 64 to rotate, and then when the fixed frame 1 is translated along the slide rail 2, the vibrating rod 4 first vibrates the concrete on the road surface evenly, and at the same time, a scraper for leveling the road surface is provided at the front end of the shovel plate 61,

[0030] The scraper is provided with an upwardly inclined inclined surface on one side facing the conveying trough 62. After the scraper flattens the road surface, the excess concrete flows along the inclined surface toward the conveying trough 62. At the same time, baffles 63 are provided on both sides of the shovel plate 61 to prevent the concrete from overflowing to both sides and causing material waste. After the excess material enters the conveying trough 62, the first drive motor 67 drives the conveying roller 64 in the conveying trough 62 to rotate, prompting the conveying roller 64 to drive the spiral blade 65 to convey the material to the connecting port 66, and then transport it to the concrete hopper 7 for storage through the feeding mechanism 8.

[0031] Furthermore, the spiral blades 65 are provided with two pairs, and are distributed from the middle to both ends of the conveying roller 64 respectively. The rotation directions of the two spiral blades 65 are opposite, and the connecting port 66 is provided corresponding to the middle of the conveying roller 64. Therefore, when the conveying roller 64 drives the two pairs of spiral blades 65 to rotate, the materials on both sides of the conveying trough 62 are prompted to move quickly to the middle, and thus enter the feeding mechanism 8 through the connecting port 66. Compared with setting a unidirectional spiral blade 65, which prompts the material at one end of the conveying trough 62 to move to the connecting port 66 at the other end through the spiral blade 65, the material conveying time is shortened, thereby accelerating the recovery efficiency of excess material.

[0032] like Figure 4-5 As shown, specifically, the feeding mechanism 8 includes a conveying pipe 81, a spiral feeding rod 82 arranged in the conveying pipe 81, one end of the conveying pipe 81 is connected to the connecting port 66, and the other end is provided with a first discharge pipe 83 extending toward the feed port of the concrete hopper 7, and the conveying pipe 81 is also provided with a second drive motor 84 for driving the spiral feeding rod 82 to rotate, and then when the excess material is transported to the connecting port 66 through the recovery device 6, the second drive motor 84 drives the spiral feeding rod 82 to rotate, thereby prompting the material at the bottom of the conveying pipe 81 to be transported upward and discharged into the concrete hopper 7 through the first discharge pipe 83.

[0033] like Figure 5-6As shown, specifically, the discharging mechanism 9 includes a discharging pump 91, one end of which is connected to the discharging port of the concrete hopper 7 through a connecting pipe 92, and the other end is provided with a second discharging pipe 93 extending toward the road surface, and also includes a sliding mechanism for driving the discharging pump 91 and the second discharging pipe 93 to move horizontally along the fixed frame 1. Therefore, when the ultrasonic ranging sensor 10 detects that the distance exceeds the standard value, it is judged that there is a depression in the road surface of the corresponding area, so that the sliding mechanism is controlled by an electrical signal to drive the discharging pump 91 and the second discharging pipe 93 to move to the depressed position. After the movement is completed, the discharging pump 91 starts and transports the recovered materials in the concrete hopper 7 to the second discharging pipe 93 for discharge through the connecting pipe 92, thereby completing the filling of the depressed part. When the ultrasonic ranging sensor 10 detects that the distance is equal to the standard value, the discharging pump 91 stops working, and as the fixed frame 1 moves forward, the leveling roller 5 performs secondary leveling on the road surface to ensure the flatness of the road surface after filling.

[0034] like Figure 8 As shown, the second discharge pipe 93 is tilted downward from top to bottom and from left to right, and the end of the second discharge pipe 93 is located on the left side of the ultrasonic ranging sensor 10, thereby ensuring that the concrete discharge position of the second discharge pipe 93 corresponds to the detection position of the ultrasonic ranging sensor 10, and at the same time avoiding the second discharge pipe 93 from blocking the ultrasonic ranging sensor 10 and causing inaccurate detection values ​​of the ultrasonic ranging sensor 10.

[0035] like Figure 5-7 As shown, the fixed frame 1 is provided with a through groove 11 for the discharge pump 91 and the second discharge pipe 93 to penetrate and move laterally along the fixed frame 1, and the sliding mechanism includes a sliding block 94 slidably connected to the through groove 11, and one end of the sliding block 94 is provided with a limiting protrusion 95 extending toward the through groove 11, one side of the through groove 11 is provided with a guide groove 12 cooperating with the limiting protrusion 95, and the other side is provided with a transmission screw 96 driving the sliding block 94 to slide along the length direction of the guide groove 12, and the fixed frame 1 is provided with a driving mechanism 97 for driving the transmission screw 96 to rotate, and then when the ultrasonic ranging sensor 10 detects that the distance exceeds the standard value, the driving mechanism 97 is controlled by an electrical signal to drive the transmission screw 96 to rotate, thereby prompting the sliding block 94 to slide in the through groove 11, and at the same time, the limiting protrusion 95 slides along the guide groove 12, thereby driving the discharge pump 91 and the second discharge pipe 93 to move to the corresponding recessed position and fill the recessed position.

[0036] The discharging mechanism 9 further comprises a slide bar 98 which is arranged on the fixed frame 1 and parallel to the driving screw 96. The slide bar 98 is located between the concrete hopper 7 and the discharging pump 91. The slide bar 98 is provided with an axially extending guide rail 99. A slide seat 910 is slidably connected to the slide bar 98. The slide seat 910 is provided with a guide block 911 which cooperates with the guide rail 99. Two rollers 912 which are arranged in parallel along the length direction of the slide bar 98 are provided on the top of the slide seat 910. A self-resetting spring 913 is provided on the outer side of the slide bar 98. The self-resetting spring 913 is located on either side of the slide seat 910. A gap is provided between the two rollers 912 for the connecting pipe 92 to pass through. One end of the connecting pipe 92 is connected to the discharge port of the concrete hopper 7, and the other end passes through the gap between the two rollers 912 and is connected to the feed port of the discharge pump 91. Then, during the translation of the discharge pump 91 and the second discharge pipe 93 along the through groove 11, the self-resetting spring 913 pushes the slide seat 910 to slide along the slide rod 98 to the other end, causing the connecting pipe 92 to bend around the gap between the two rollers 912. The connecting pipes 92 on the front and rear sides of the rollers 912 remain straight, which is conducive to the rapid transportation of concrete in the connecting pipe 92 and avoids the connection pipe 92 from bending and entangled together after the sliding mechanism drives the discharge pump 91 to translate back and forth, resulting in the concrete in the connecting pipe 92 being unable to be transported normally or being transported slowly.

[0037] Specifically, the diameter of the roller 912 gradually increases from the middle to both ends, and the gap between the two rollers 912 is equal to the circular cross-section of the connecting pipe 92, thereby preventing the two rollers 912 from squeezing the connecting pipe 92, causing the diameter of the connecting pipe 92 to be compressed, thereby ensuring normal transportation of concrete in the connecting pipe 92.

[0038] like Figure 5 As shown, further, a stirring rod 71 is provided inside the concrete hopper 7, and a driver 72 for driving the stirring rod 71 is provided outside the concrete hopper 7. When the material is recovered and transported to the concrete hopper 7 through the feeding mechanism 8, the stirring rod 71 is driven by the driver 72 to rotate, so that the recovered material in the concrete hopper 7 is evenly stirred, and the concrete can also be prevented from solidifying and hardening.

[0039] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0040] Therefore, no matter from which point of view, the embodiments should be regarded as illustrative and non-restrictive, and the scope of the present invention is limited by the appended claims rather than the above description, so it is intended that all changes falling within the meaning and range of equivalent elements of the claims are included in the present invention. Any reference sign in the claims should not be regarded as limiting the claims involved.
