Description

Technical Field

[0001] The present application relates to the technical field of roadbed detection, and in particular to a ground flatness detection device with a leveling function for roadbed construction. Background Art

[0002] The roadbed of a highway refers to the basic part of highway construction. It supports the entire highway structure, carries the weight of vehicles and pedestrians, and disperses traffic loads. The roadbed construction technology includes two types: interlocking type and graded type. The interlocking type includes mud-bound crushed stone, mud-lime-bound crushed stone and gap-filled crushed stone. Among them, gap-filled crushed stone can be used for the subbase of highways of all grades and the roadbed of highways below the second grade. The graded type includes graded crushed stone, graded gravel, graded natural sand and gravel, and first-grade gravel and crushed stone made by rolling some gravel.

[0003] After the roadbed construction is completed, the roadbed surface needs to be tested for flatness. After the flatness test is completed, the uneven positions detected by workers need to be leveled, or the detected uneven positions need to be leveled by using instruments. However, the uneven positions cannot be leveled immediately when they are detected, which leads to low highway construction efficiency. Summary of the invention

[0004] In order to improve the construction efficiency of highways, the present application provides a ground flatness detection device with a leveling function for roadbed construction.

[0005] The present application provides a ground flatness detection device with a leveling function for roadbed construction, which adopts the following technical solution:

[0006] A ground flatness detection device with a leveling function for roadbed construction, comprising:

[0007] The mobile slide rails are installed on both sides of the roadbed and are parallel to the required layout plane of the roadbed;

[0008] A flatness detector is connected to the movable slide rail and is provided with a detection plate, the detection plate can move on the required layout plane of the roadbed, and a marking mechanism is connected to the side of the detection plate away from the roadbed, and the marking mechanism is used to mark the unevenness of the roadbed;

[0009] The leveling device is connected to the flatness detector and is provided with a cutting knife, and the cutting knife can move on the required layout plane of the roadbed.

[0010] By adopting the above technical solution, when the flatness of the roadbed is detected, the detection plate can slide on the required layout plane of the roadbed by moving the slide rail. When encountering a position higher than the required layout plane of the roadbed, the detection plate can make the marking mechanism mark, so that the leveling device starts to work, and the cutting knife cuts off the position higher than the required layout plane of the roadbed, and then moves the detection plate to the marked position again to determine whether the marked position is flat. After the flatness detector detects the flatness of the roadbed, the place where the flatness of the roadbed is insufficient can be leveled immediately, thereby improving the construction efficiency of the highway.

[0011] Optionally, the marking mechanism includes an elastic member and a signal trigger, one end of the elastic member is connected to the detection plate, and the signal trigger is connected to the other end of the elastic member, and the signal trigger is used to mark the unevenness signal.

[0012] By adopting the above technical solution, when the detection plate encounters an uneven roadbed, the detection plate moves toward the direction of the signal trigger under the action of the reaction force provided by the roadbed, so that the signal trigger operates and marks the location. When the detection plate leaves the uneven ground, the detection plate returns to the required layout plane of the roadbed under the action of the elastic member.

[0013] Optionally, the leveling device also includes a leveling motor and a lifting mechanism, the bottom end of the cutting knife is located at the plane where the roadbed is required to be laid out, the leveling motor is located on the side of the cutting knife away from the roadbed, the leveling motor is used to drive the cutting knife to rotate, and the lifting mechanism is located on the side of the leveling motor away from the cutting knife, and the lifting mechanism is used to drive the cutting knife to move in a direction perpendicular to the plane where the roadbed is located.

[0014] By adopting the above technical solution, when the leveling device is leveling the uneven road surface, the leveling motor drives the cutting knife to rotate, so that the cutting knife cuts off the uneven road surface. When the uneven part of the road surface is difficult to cut, the thickness of the road surface to be cut at one time can be reduced by the lifting mechanism, and the uneven part of the road surface can be cut off in batches, so as to facilitate the removal of the uneven road surface.

[0015] Optionally, the cutting knife is disc-shaped, and a plurality of blades located in the same plane are arranged at the bottom end of the cutting knife.

[0016] By adopting the above technical solution, the blade of the cutting knife is arranged at the bottom, thereby reducing the probability of the blade of the cutting knife being exposed to the outside, thereby reducing the safety hazard when using the cutting knife.

[0017] Optionally, the size of the blade gradually decreases from the direction away from the center of the cutting knife toward the center of the cutting knife.

[0018] By adopting the above technical solution, when the cutting knife rotates, the speed of the blade away from the center of the cutting knife is faster, and the blade away from the center of the cutting knife is set larger, which can reduce the probability of damage to the blade of the cutting knife.

[0019] Optionally, a collecting hole is opened at the center of the cutting knife, and the ends of the blade are connected to the collecting hole.

[0020] By adopting the above technical solution, the collecting hole can collect the roadbed material cut by the cutting knife and transport it out from the collecting hole.

[0021] Optionally, the blade is arranged in an arc shape along the rotation direction.

[0022] By adopting the above technical solution, the arc-shaped blade can make it easier for the road base surface material cut by the cutting knife to be collected in the center of the cutting knife and collected by the collecting hole in the center of the cutting knife.

[0023] Optionally, a screening device is connected to the side of the cutting knife facing away from the ground, and the screening device is used to screen the roadbed material collected by the collecting hole.

[0024] By adopting the above technical solution, the screening device can screen the materials collected by the collecting holes, making it convenient for the subsequent use of the materials collected by the collecting holes.

[0025] Optionally, the collecting hole is connected to the side of the cutting knife facing away from the ground, and the hole wall of the collecting hole facing away from the ground is connected to a collecting plate, and a gap is left between the collecting plate and the upper end surface of the cutting knife. The screening device includes a receiving plate and a plurality of screening plates, and the height of the receiving plate is between the collecting plate and the cutting knife. The screening plate is vertically connected to the receiving plate and is located on the outside of the collecting plate, and adjacent screening plates are arranged at intervals.

[0026] By adopting the above technical solution, after the material collected by the collecting hole is transported to the collecting plate, it moves in the direction away from the collecting hole under the action of centrifugal force. When the material leaves the collecting plate, it falls to different positions on the receiving plate under the combined action of centrifugal force and its own gravity, and is blocked by different screening plates, thereby realizing the screening of the collected material.

[0027] Optionally, the receiving plate portion is disposed in a gap between the collecting plate and the cutting knife.

[0028] By adopting the above technical solution, the receiving plate partially located in the gap between the collecting plate and the cutting knife can reduce the probability that the material on the collecting plate falls directly onto the roadbed after being separated from the collecting plate.

[0029] In summary, the present application includes at least one of the following beneficial technical effects:

[0030] 1. By moving the slide rail, the detection plate can move on the required plane of the roadbed. When the detection plate encounters a position higher than the required plane of the roadbed, the detection plate will make the marking mechanism mark at the secondary position, and then drive the leveling device to start working. The cutting knife can immediately level the unevenness detected by the detection plate, thereby improving the construction efficiency of the highway;

[0031] 2. When the detection plate encounters an uneven roadbed, the detection plate moves away from the roadbed surface under the reaction force of the roadbed, thereby compressing the elastic member and triggering the signal trigger to mark the location. When the roadbed surface returns to a flat surface, the detection plate can return to the required plane of the roadbed under the action of the elastic member, facilitating the detection of other locations;

[0032] 3. After the cutting knife cuts off the uneven part of the roadbed surface, the collecting hole collects the cut roadbed material and screens it through the screening device. The screened material can be used to fill the roadbed surface. The material screened by the screening device can be used in different scenarios according to different screening conditions, thereby improving the utilization rate of the roadbed material.

DETAILED DESCRIPTION

[0038] The following is combined with Figure 1-4 This application is described in further detail.

[0039] The present application embodiment discloses a ground flatness detection device with a leveling function for roadbed construction. Figure 1 and Figure 2A ground flatness detection device with a leveling function for roadbed construction includes a movable slide rail 1, a flatness detector 2 and a leveling device 3.

[0040] The movable slide rail 1 is installed on both sides of the roadbed, and the upper surface of the movable slide rail 1 is parallel to the required layout plane of the roadbed. The flatness detector 2 is connected to the movable slide rail 1, and the end of the flatness detector 2 facing the roadbed is arranged as a detection plate 21, and the detection plate 21 is arranged parallel to the required layout plane of the roadbed, and the side of the detection plate 21 away from the roadbed is connected to a marking mechanism 22. The leveling device 3 is connected to the flatness detector 2, and the leveling device 3 is located behind the flatness detector 2 along the moving direction of the flatness detector 2. The leveling device 3 is arranged with a cutting knife 31, and the bottom end of the cutting knife 31 is arranged parallel to the required layout plane of the roadbed.

[0041] When testing the flatness of the roadbed surface, the detection plate 21 on the flatness detector 2 can slide on the required layout plane of the roadbed under the action of the moving slide rail 1. When the roadbed surface is convex, the detection plate 21 will be subjected to the reaction force and move away from the ground, thereby triggering the marking mechanism 22 to make a mark there, and at the same time starting the leveling device 3. After the detection plate 21 passes the position, the leveling device 3 can immediately level the position. Finally, the construction speed of the highway is accelerated and the construction efficiency of the highway is improved.

[0042] Reference Figure 1 and Figure 2 The marking mechanism 22 includes an elastic member 221 and a signal trigger 222. One end of the elastic member 221 is connected to the detection plate 21, and the signal trigger 222 is connected to the other end of the elastic member 221. The elastic member 221 is preferably a spring or an elastic block. The signal trigger 222 is arranged at a distance from the detection plate 21, and the trigger end of the signal trigger 222 is arranged opposite to the detection plate 21.

[0043] When the detection plate 21 encounters a raised ground, the detection plate 21 moves toward the signal trigger 222, compressing the elastic member 221, and the side of the detection plate 21 facing away from the roadbed abuts against the signal trigger 222, causing the signal trigger 222 to work, marking the position, and driving the leveling device 3 to start working. When the detection plate 21 passes the raised part, the leveling device 3 can level the raised part. After the flatness detector 2 moves once on the moving slide rail 1, the flatness detector 2 moves in the opposite direction once, and the leveling device 3 is started again when passing the marked position. After the leveling device 3 passes, the marked position is detected again by the detection plate 21, thereby increasing the probability that the marked position is leveled.

[0044] Reference Figure 1 and Figure 3The leveling device 3 also includes a leveling motor 32 and a lifting mechanism 33. The bottom end of the cutting knife 31 is located at the required layout plane of the roadbed. The leveling motor 32 is fixedly connected to the end of the cutting knife 31 away from the roadbed. The leveling motor 32 is coaxially connected to the cutting knife 31. The lifting mechanism 33 is located on the side of the leveling motor 32 away from the cutting knife 31. The lifting mechanism 33 is preferably a telescopic cylinder.

[0045] When the leveling device 3 is leveling the plane where the roadbed is located, the leveling motor 32 drives the cutting knife 31 to rotate, and the cutting knife 31 cuts off the part that is higher than the required plane of the roadbed. When the cutting knife 31 cannot level the raised part at one time, the lifting mechanism 33 can drive the cutting knife 31 to move up and down, and cut off the part that is higher than the required plane of the roadbed in batches, thereby facilitating the leveling of the roadbed surface and reducing the probability of damage to the cutting knife 31.

[0046] Reference Figure 1 and Figure 4 The cutting knife 31 is disc-shaped, and a plurality of blades 311 in the same plane are arranged at the bottom end of the cutting knife 31. The number of blades 311 is preferably 3, 4, or 5. The size of the blades 311 gradually decreases from the direction away from the center of the cutting knife 31 toward the center of the cutting knife 31, and the blades 311 are arranged in an arc shape along the rotation direction of the cutting knife 31. A collecting hole 312 is opened in the center of the cutting knife 31, and the ends of the blades 311 are connected to the collecting hole 312. The collecting hole 312 is arranged as a through hole, and a collecting plate 313 is connected to the hole wall on the side of the collecting hole 312 facing away from the ground, and a gap is left between the collecting plate 313 and the upper end surface of the cutting knife 31.

[0047] When the cutting knife 31 is cutting, the blade 311 at the bottom of the cutting knife 31 can reduce safety hazards. When the cutting knife 31 rotates, the farther away from the center of the cutting knife 31, the greater the linear speed of the blade 311. Therefore, the size of the blade 311 gradually decreases from the position far away from the center of the cutting knife 31 to the center of the cutting knife 31, which can reduce the probability of damage to the blade 311. The arc-shaped blade 311 can guide the soil or stone on the roadbed surface cut by the cutting knife 31 to the collection hole 312 in the center of the cutting knife 31 when the cutting knife 31 rotates, and then the soil or stone is collected by the collection hole 312. After the soil, gravel and other materials are collected by the collection hole 312, they can be used to fill the concave part of the roadbed surface, making the roadbed surface smoother. The gravel or soil collected by the collection hole 312 will rotate with the collection plate 313 after entering the collection plate 313 through the collection hole 312.

[0048] Reference Figure 3 and Figure 4The side of the cutting knife 31 facing away from the ground is connected with a screening device 4, which includes a receiving plate 41 and a plurality of screening plates 42, and the number of the screening plates 42 is preferably 2, 3, or 4. The height of the receiving plate 41 is between the collecting plate 313 and the cutting knife 31, and the receiving plate 41 is partially arranged in the gap between the collecting plate 313 and the cutting knife 31. The top of the screening plate 42 is lower than the upper surface of the collecting plate 313, and the screening plate 42 is vertically fixedly connected to the receiving plate 41. The screening plate 42 is arranged around the outer side of the collecting plate 313, and adjacent screening plates 42 are arranged at intervals.

[0049] After the soil and gravel on the roadbed surface are collected by the collecting holes 312, the soil and gravel will rotate with the rotation of the collecting plate 313, so that the soil and gravel are affected by the centrifugal force and move away from the center of the collecting plate 313. After the soil and gravel are separated from the collecting plate 313, the soil and gravel fall under the action of gravity and inertia, and are blocked by different screening plates 42, thereby achieving the screening of soil and gravel. According to the screening results, the soil and gravel can be used in different situations. For example, the gravel can be used to fill the depressions on the roadbed surface first, and then the depressions on the roadbed surface can be filled again by the soil. The receiving plate 41 partially located in the gap between the collecting plate 313 and the cutting knife 31 can reduce the probability of the soil or gravel on the collecting plate 313 falling directly onto the roadbed surface.

[0050] Adjustment screw rods (not marked in the drawings) are arranged at both ends of the movable slide rail 1, and a level gauge (not marked in the drawings) is arranged in the middle of the movable slide rail 1. When laying out the movable slide rail 1, one end of the movable slide rail 1 can be laid out to the required roadbed layout plane, and then the other end of the movable slide rail 1 can be adjusted so that the level gauge in the middle of the movable slide rail 1 is in a horizontal position, and then the movable slide rail 1 is fixed, thereby achieving the effect of fixing the movable slide rail 1 on the required layout plane of the roadbed.

[0051] The implementation principle of the ground flatness detection device with a leveling function for roadbed construction in the embodiment of the present application is as follows: when the flatness of the roadbed surface is detected, under the action of the moving slide rail 1 parallel to the required layout plane of the roadbed, the detection plate 21 can move on the required layout plane of the roadbed. When a bulge appears on the roadbed surface that is higher than the required layout plane of the roadbed, the detection plate 21 will be driven by the reaction force of the bulge position when passing through the bulge position to move away from the roadbed surface, so that the marking mechanism 22 makes a mark, and the leveling device 3 is started at the same time, and the bulge is leveled by the leveling device 3. When an uneven position on the roadbed surface is detected, the uneven position can be leveled immediately, thereby improving the construction efficiency of the highway.

[0052] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
