Description

Technical Field

[0001] The present invention relates to the technical field related to road surface detection, and in particular to a device and method for detecting the smoothness of asphalt road surface construction on a highway. Background Art

[0002] An expressway refers to a highway with at least two lanes in one direction, restrictions on vehicles allowed to enter, a central dividing strip to separate oncoming traffic, and the use of interchange access and other measures to fully control entry and exit, eliminate longitudinal and lateral interference, and have high traffic efficiency.

[0003] After the construction of the expressway is completed, a flatness test will be carried out to ensure the flatness of the expressway.

[0004] After searching, a highway pavement smoothness detection device was disclosed, with announcement number: CN215329227U;

[0005] The device uses a brush roller to roll on the road surface, leaving continuous water marks on the road surface. When the water marks are broken or discontinuous, it indicates that the road surface is uneven.

[0006] This method is suitable for short-distance road construction inspections, but not for highways, as highways are long and water marks cannot stay for a long time, and are also difficult to observe on asphalt roads.

[0007] Secondly, this method cannot obtain the specific concavity or convexity information of the road, nor can it determine the degree of concavity or convexity. Summary of the Invention

[0019] Furthermore, the transmission assembly includes a worm gear rotatably mounted on the bottom of the connecting plate, and the rotating shaft of the worm gear is detachably connected to the rotating shaft of the winding roller;

[0020] A worm is rotatably mounted on the fixed frame and meshes with the worm wheel. A first transmission rod is also slidably mounted on the fixed frame. The first transmission rod is slidably connected to the worm via an axial sliding member.

[0021] A second transmission rod is rotatably mounted on the base, the second transmission rod is connected to the first roller via a bevel gear set, and the second transmission rod is also connected to the first transmission rod via a universal coupling;

[0022] The axial sliding member includes a transmission groove opened on the worm and a transmission bar fixed on the first transmission rod, and the transmission groove is slidably connected to the transmission bar.

DETAILED DESCRIPTION

[0061] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying 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 efforts are within the scope of protection of the present invention.

[0062] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0063] The following is based on Figures 1-17 The present invention provides a device for detecting the smoothness of asphalt pavement construction on a highway.

[0064] like Figures 1-17 As shown, an embodiment of the present invention provides a technical solution: a device for detecting the smoothness of asphalt pavement construction on a highway, comprising a plurality of fixing frames 2 arranged in a rectangular shape, the tops of the plurality of fixing frames 2 being fixed by a connecting plate 201, the connecting plate 201 being connected to the front end of a vehicle body, and further comprising:

[0065] The sleeve plate 6 is fixed in multiple fixing frames 2, and the base 1 is slidably installed in the fixing frame 2. The bottom of the base 1 is rotatably installed with a number 1 roller 101. The top of the base 1 is fixed with a transmission frame 104, and the transmission frame 104 is connected to the feedback mechanism installed on the top of the connecting plate 201.

[0066] The resistance roller 102 is fixed in the base 1 , and a resistance slider 103 cooperating therewith is slidingly sleeved on the base 1 . A plurality of No. 1 guide rods 105 are also fixed in the base 1 , and the resistance slider 103 is slidably mounted on the No. 1 guide rods 105 .

[0067] The cleaning mechanism installed on the sleeve plate 6 is used to clean obstacles in front of the No. 1 roller 101.

[0068] In the embodiment of the present invention, the connecting plate 201 is fixed to the front of the vehicle, and the resistance roller 102 is driven forward by the vehicle.

[0069] When the vehicle moves forward, it drives the connecting plate 201, the fixing frame 2, the base 1 and the first roller 101 to move forward together. When the base 1 and the first roller 101 move forward, the first roller 101 moves forward in a rolling state because the first roller 101 contacts the ground.

[0070] The base 1 and the number one roller 101 are actually in contact with the ground due to gravity, and the sleeve 6 only limits the number one roller 101. Therefore, the base 1 and the number one roller 101 will not be affected by the vehicle's position when it is on a concave or convex road section, and only the base 1 and the number one roller 101 will not fall over.

[0071] The sliding engagement between the resistor slider 103 and the first guide rod 105 creates a certain sliding locking force. When the base 1 and the first roller 101 encounter an uneven surface, they experience a certain degree of inertia. This inertia overcomes the sliding locking force between the resistor slider 103 and the first guide rod 105, allowing the resistor slider 103 to descend or ascend on the resistor roller 102, resulting in a change in resistance. By recording and analyzing this change in resistance, it is possible to determine whether the road surface is uneven.

[0072] Among them, the above-mentioned sliding lock means that the resistance slider 103 and the guide rod No. 105 are in a sliding connection state, and the friction force between the two is slightly greater than the critical point. In the state without inertia, the resistance slider 103 is in a stationary state on the guide rod No. 105. When inertia is generated, the resistance slider 103 is located on the guide rod No. 105 and slides upright.

[0073] It should also be noted that when the base 1 is in a concave or convex position and performs an upright movement, the movement will drive the transmission frame 104 to move synchronously through the base 1. When the transmission frame 104 moves, it will drive the feedback mechanism to work, and the feedback mechanism will record the road surface information in written form.

[0074] In addition, when the detection work is carried out, the cleaning mechanism will work synchronously to clean the road surface in front of the forward direction of the No. 1 roller 101 to prevent stones, branches and other objects on the road surface from affecting the detection results.

[0075] In summary, the present invention obtains electronic data and written data by causing the base 1 and the first roller 101 to rise or fall according to the unevenness of the ground.

[0076] A first baffle 5 and a second baffle 501 are fixed to the top and bottom of the connecting plate 201 respectively.

[0077] The feedback mechanism includes a follower frame 9 fixed on the transmission frame 104. The follower frame 9 passes through the connecting plate 201 and is slidably connected thereto. A first through slot 908 and a second through slot 909 are provided on the follower frame 9. A follower printing assembly is installed on the follower frame 9.

[0078] Two positioning rollers 906 are installed on the connecting plate 201 on both sides of the follower frame 9. A unwinding roller 802 is rotatably installed on the top of the connecting plate 201, and a winding roller 8 is rotatably installed on the bottom of the connecting plate 201. The unwinding roller 802 and the winding roller 8 are connected by a recording tape 801, and the winding roller 8 is connected to the number one roller 101 through a transmission assembly.

[0079] A plurality of guide rollers 907 for guiding and limiting the recording tape 801 are installed on the top or bottom of the connecting plate 201 .

[0080] In the embodiment of the present invention, when the base 1 rolls forward, the transmission assembly drives the winding roller 8 to rotate, and then the rotation of the winding roller 8 reels and conveys the recording tape 801 wound on the unwinding roller 802.

[0081] When the recording tape 801 is being transported, if the base 1 or the first roller 101 moves to an uneven position, the base 1 moves upright to drive the follower frame 9 to move synchronously, and then two different patterns are printed on the recording tape 801 through the follower printing component, and the unevenness of the road surface is recorded by printing the patterns.

[0082] The function of the two positioning rollers 906 is to provide the recording tape 801 with a certain pressure resistance so that the recording tape 801 will not bend excessively when subjected to pressure, thereby preventing the recording tape 801 from causing discontinuous printing.

[0083] The conveying track of the recording tape 801 is as follows: the recording tape 801 is wound onto the unwinding roller 802 , then passes through the No. 1 slot 908 , is guided by the guide roller 907 , passes through the No. 2 slot 909 , and finally is wound onto the winding roller 8 .

[0084] The follow-up printing assembly includes two sets of slide bars 901 relatively slidably mounted in the No. 1 through slot 908 , and printing rollers 903 are rotatably mounted on opposite ends of the two sets of slide bars 901 , and No. 2 springs 902 are sleeved on the two sets of slide bars 901 .

[0085] The length of a single set of sliding bars 901 increases or decreases in sequence, and the recording tape 801 is located between the two sets of sliding bars 901 .

[0086] The top printing roller 903 is provided with a recessed pattern 904 , and the bottom printing roller 903 is provided with a raised pattern 905 .

[0087] The decreasing or increasing distance of a single set of sliding bars 901 is 0.25 cm.

[0088] In the embodiment of the present invention, the movement of the base 1 and the first roller 101 to the concave or convex position corresponds to the vertical rise or fall of the base 1, so that the rise or fall of the base 1 drives the follower frame 9 to rise or fall synchronously.

[0089] When the base 1 and the follower frame 9 descend, they correspond to the depression in the road surface. At this time, the follower frame 9 drives the top printing roller 903 to descend and abut against the recording tape 801, so that the printing roller 903 is driven to rotate along with the transportation of the recording tape 801, and the depression pattern 904 is printed on the front of the recording tape 801 in a rolling printing manner.

[0090] When the base 1 and the follower frame 9 rise, they correspond to the bumps on the road surface. At this time, the follower frame 9 drives the bottom printing roller 903 to rise and abut against the recording tape 801, so that the printing roller 903 is driven to rotate as the recording tape 801 is transported. The raised pattern 905 is also printed on the back of the recording tape 801 in a rolling printing manner, and then when there are depressions or bumps on the road surface, corresponding records will be left on the recording tape 801.

[0091] like Figure 10 As shown, in this embodiment, the height of the printing roller 903 is successively decreased or increased, and one or more printing rollers 903 can be used for printing according to the degree of depression or protrusion of the road surface, so as to achieve the technical effect of showing the degree of protrusion or depression while recording the depression or protrusion of the road surface.

[0092] Among them, in order to prevent the recording tape 801 and the printing roller 903 from separating, when the printing roller 903 contacts the recording tape 801, the No. 2 spring 902 will be compressed to a certain extent. The elastic potential energy of the No. 2 spring 902 ensures that the concave pattern 904 and the recording tape 801 are in contact. When the base 1 and the No. 1 roller 101 move to a parallel section, the unwinding roller 802 will completely release the elastic potential energy to drive the printing roller 903 to reset.

[0093] like Figure 17 As shown, a scale for reference distance is printed on the recording tape 801.

[0094] The transmission assembly includes a worm gear 7 rotatably mounted on the bottom of the connecting plate 201 , and the rotating shaft of the worm gear 7 is detachably connected to the rotating shaft of the winding roller 8 .

[0095] A worm 701 meshing with the worm wheel 7 is rotatably mounted on the fixed frame 2 , and a No. 1 transmission rod 702 is also slidably mounted on the fixed frame 2 . The No. 1 transmission rod 702 is slidably connected to the worm 701 via an axial sliding member.

[0096] A second transmission rod 704 is rotatably mounted on the base 1 . The second transmission rod 704 is connected to the first roller 101 via a bevel gear set 705 . The second transmission rod 704 is also connected to the first transmission rod 702 via a universal coupling 703 .

[0097] The axial sliding member includes a transmission groove 707 formed on the worm 701 and a transmission bar 706 fixed on the first transmission rod 702 . The transmission groove 707 is slidably connected to the transmission bar 706 .

[0098] In the embodiment of the present invention, when the No. 1 roller 101 rotates, the No. 2 transmission rod 704 is driven to rotate through the bevel gear set 705, and the No. 2 transmission rod 704 drives the No. 1 transmission rod 702 to rotate through the universal coupling 703, so as to drive the worm 701 to rotate through the cooperation of the transmission groove 707 and the transmission bar 706. When the worm 701 rotates, it drives the worm wheel 7 and the winding roller 8 to rotate through the engagement with the worm wheel 7, so as to drive the worm 701 to rotate through the rotation of the No. 1 roller 101. The rotation of the worm wheel 7 driven by the rotation of the worm 701 can reduce the speed and increase the torque, so that the torque driving the winding roller 8 to rotate is greatly reduced. Moreover, since the rotation of the winding roller 8 corresponds to the transportation of the recording tape 801, the recording tape 801 is used to record road surface information. If the length of the recording tape 801 is equal to the length of the road surface, the waste of the recording tape 801 is relatively large.

[0099] The transmission deceleration of the present invention can greatly reduce the waste of the recording tape 801, because the rotation of the worm 701 corresponds to the rotation of the first roller 101, and the worm 701 needs to rotate several circles to drive the worm wheel 7 to rotate one circle.

[0100] Among them, the cooperation between the transmission groove 707 and the transmission bar 706 is to enable the worm 701 to rotate synchronously with the No. 1 transmission rod 702, and the No. 1 transmission rod 702 can slide axially relative to the worm 701. Because the base 1 and the No. 1 roller 101 will rise and fall according to the road conditions when moving forward, the rise and fall of the base 1 will inevitably drive the No. 2 transmission rod 704 to rise and fall synchronously. In order to avoid affecting the transmission, when the No. 2 transmission rod 704 rises and falls, it will drive the No. 1 transmission rod 702 to perform upright lifting movement through the universal coupling 703, and the lifting movement of the No. 1 transmission rod 702 will not affect the synchronous rotation of the worm 701 and the No. 1 transmission rod 702.

[0101] The cleaning mechanism includes a connecting frame 3 rotatably mounted on the sleeve plate 6. A cleaning roller 301 is rotatably mounted on one end of the connecting frame 3 away from the sleeve plate 6. A tension spring 302 is rotatably mounted on the bottom of the connecting frame 3. The other end of the tension spring 302 is rotatably connected to the sleeve plate 6.

[0102] A driving assembly is installed at the bottom of the fixing frame 2 , and the driving assembly is connected to the cleaning roller 301 .

[0103] In this embodiment of the present invention, when the vehicle moves forward, the connecting frame 3 and the cleaning roller 301 are driven forward together by the connecting plate 201 and the fixing frame 2. At the same time, the driving assembly is activated, which drives the cleaning roller 301 to rotate, thereby cleaning the area in front of the forward direction of the first roller 101.

[0104] In view of the possible unevenness of the road surface, the rotation of the tension spring 302 and the cleaning roller 301 can keep the cleaning roller 301 in contact with the ground at all times, thereby preventing the cleaning roller 301 from being in the air and unable to perform cleaning.

[0105] A plurality of groups of bristles are fixed on the cleaning roller 301 and are arranged at equal intervals around the circumference.

[0106] The bristles are arranged in relative spirals.

[0107] In the embodiment of the present invention, when the cleaning roller 301 rotates for cleaning, the bristles of the cleaning roller 301 are moved in opposite directions. This method of moving the cleaning roller 301 to clean the road surface can prevent stones and branches from being splashed when the cleaning roller 301 rotates, and prevents impurities from remaining on the cleaned road surface.

[0108] The driving assembly includes a movable groove 406 opened at the bottom of the fixed frame 2, and a mounting plate 405 is slidably installed in the movable groove 406. A No. 3 spring is fixed on the top of the mounting plate 405, and the other end of the No. 3 spring is fixed to the bottom of the movable groove 406.

[0109] The mounting plate 405 is rotatably mounted with the second roller 4 at one end away from the third spring, and the second roller 4 is coaxially fixed with the second gear 403. The mounting plate 405 is rotatably mounted with the first gear 402 meshing with the second gear 403, and the first gear 402 is connected to the cleaning roller 301 through a synchronous belt 404.

[0110] A tensioning member for adjusting the tension of the synchronous belt 404 is also installed on the mounting plate 405 .

[0111] In the embodiment of the present invention, after the fixing frame 2 is fixed to the vehicle, the No. 3 spring is compressed. The elastic potential energy of the No. 3 spring applies a force toward the ground to the mounting plate 405 and the No. 2 roller 4, thereby increasing the friction between the No. 2 roller 4 and the ground. When the fixing frame 2 and the connecting plate 201 move forward, the mounting plate 405 moves synchronously, and the No. 2 roller 4 rotates due to contact with the ground.

[0112] When the second roller 4 rotates, it drives the second gear 403 to rotate. When the second gear 403 rotates, the engagement between the second gear 403 and the first gear 402 drives the first gear 402 and the second roller 4 to rotate in the opposite direction. When the first gear 402 rotates, it drives the cleaning roller 301 to rotate through the synchronous belt 404.

[0113] For example, if the second roller 4 rotates counterclockwise, if the second roller 4 is directly connected to the cleaning roller 301 through the synchronous belt 404, the cleaning roller 301 is actually in the same rolling state, and the cleaning effect is poor.

[0114] By meshing the first gear 402 and the second gear 403 , the rotation of the second roller 4 is reversed, so that when the second roller 4 rotates counterclockwise, the cleaning roller 301 rotates clockwise. This design can effectively improve the cleaning effect of the cleaning roller 301 .

[0115] The tensioning member includes an assembly groove 407 opened on the mounting plate 405, and a No. 2 guide rod 408 is fixed in the assembly groove 407. A slide 4010 is slidably installed on the No. 2 guide rod 408, and an adjusting roller 401 connected to the synchronous belt 404 is rotatably installed on the slide 4010. A No. 1 spring 409 is also sleeved on the No. 2 guide rod 408, and one end of the No. 1 spring 409 is fixed to the inner wall of the assembly groove 407, and the other end is fixed to the slide 4010.

[0116] In the embodiment of the present invention, since the connecting frame 3 rotates around the rotation axis, the synchronous belt 404 may be over-tensioned or under-tensioned during the rotation process.

[0117] In this embodiment, when the tension of the synchronous belt 404 increases, the first spring 409 is compressed by the adjusting roller 401 and the slide 4010, thereby preventing excessive tension in the synchronous belt 404. When the tension of the synchronous belt 404 decreases, the elastic potential energy of the first spring 409 is released, driving the slide 4010 and the adjusting roller 401 upward to compensate for the tension. In this way, when the connecting frame 3 and the cleaning roller 301 rotate, the cleaning roller 301 is in contact with the ground, and the synchronous belt 404 is neither over-tensioned nor under-tensioned.

[0118] The present invention also provides a method for detecting the smoothness of asphalt pavement construction on a highway, which uses the above-mentioned device for detecting the smoothness of asphalt pavement construction on a highway, and includes the following steps:

[0119] Step 1: Fix the connecting plate 201 to the front of the vehicle, and drive the base 1 and the first roller 101 to move synchronously when the vehicle moves;

[0120] Step 2: When the first roller 101 moves to the concave or convex part of the road, it drives the base 1 to rise or fall vertically;

[0121] Step 3: When the base 1 moves, the road condition information on the paper is obtained through the feedback mechanism, and at the same time, the electronic road surface information is obtained through the cooperation of the resistance slider 103 and the resistance roller 102.
