Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of highway detection, in particular to a road surface quality detection device for highway engineering. BACKGROUND

[0002] In highway engineering construction and maintenance, quality detection of highway pavement is a crucial link. As the infrastructure of the transportation network, the quality of the highway is directly related to the safety and comfort of driving and the service life of the road. With the continuous increase of traffic flow and the increasing weight of vehicles, higher requirements are put forward for the flatness, strength and durability of the highway pavement. Therefore, regular highway pavement quality detection is of great significance for timely detection and repair of potential pavement defects such as cracks, pits, ruts, etc., and for ensuring the normal use and prolonging the service life of the highway.

[0003] The design of highway transverse slope is an important aspect of highway construction, which usually requires the middle to be higher and the sides to be lower. This design is called road crown transverse slope. The main function of the road crown transverse slope is to promote the drainage of the road surface and prevent the accumulation of rainwater on the road surface, thereby reducing the erosion and damage of water to the road surface and improving the safety of driving. In rainy areas or seasons, reasonable design of the road crown transverse slope can effectively avoid traffic accidents such as skidding and rollover caused by water accumulation, and ensure the safety of driving.

[0004] The transverse slope of the road on both sides must be symmetrical (i.e. completely the same), which is based on the consideration of drainage efficiency and driving stability. If the transverse slope of both sides is not symmetrical, it will cause rainwater to accumulate on the lower side, which not only affects the drainage effect, but also may cause the road surface on that side to be damaged prematurely. At the same time, the asymmetrical transverse slope will also affect the driving stability of the vehicle, especially when driving at high speed or turning, which may cause lateral slip and other adverse consequences, seriously threatening the safety of driving. Therefore, ensuring the symmetry of the transverse slope of the road on both sides is an important principle in the design of highway transverse slope.

[0005] However, in the prior art, the detection of the quality of the highway pavement, especially the detection of the road crown transverse slope, often lacks reliable and efficient devices. Traditional detection methods may rely on manual measurement or simple mechanical tools, which not only have low efficiency, but also have low accuracy, and cannot meet the needs of large-scale highway construction and maintenance. In addition, the existing detection equipment often has single function, which can only detect one of the flatness or the transverse slope of the road surface, and cannot realize one machine with multiple functions, increasing the detection cost and time.

[0037] Specifically, as Figure 6As shown, the angle detection assembly comprises a rotating rod 17 rotatably arranged in the middle of the front side of the crossbeam 1 through a bearing, a dial 18 sleeved on the outer wall of the rotating rod 17, a counterweight 19 arranged at the bottom end of the inner cavity of the dial 18, and an indicating baffle 20 arranged in the middle of the front side of the crossbeam 1, the front end of the rotating rod 17 being rotatably arranged at the back side of the indicating baffle 20 through a bearing, and the dial 18 being located in the inner cavity of the indicating baffle 20.

[0038] In particular, as Figure 4 , Figure 5 , Figure 10 , Figure 11 and Figure 12As shown, the detection mechanism 8 comprises: sleeve plates 81, detection feet 82, penetration holes 83, clamping grooves 84, first springs 85, rollers 86, rotating rollers 87, shielding cloth 88, pull plates 89, extrusion grooves 810, second springs 811, clamping balls 812, and infrared sensors 813. The two sleeve plates 81 are respectively slidably embedded in the left and right sides of the inner cavity of the cross beam 1, and the front and back sides of the two sleeve plates 81 are respectively slidably sleeved on the left and right sides of the outer wall of the two guide rods 3. The synchronous movement assembly can drive the two sleeve plates 81 to move synchronously. The synchronous movement assembly drives the sleeve plates 81 to move synchronously, thereby driving the detection feet 82 and other components to detect synchronously, improving the detection efficiency and accuracy. The detection feet 82 are slidably and adaptively inserted into the inner cavity of the sleeve plate 81. The outer wall of the detection feet 82 is slidably and adaptively inserted into the inner cavity of the moving groove 2. The upper and lower ends of the detection feet 82 are respectively slidably extended out of the upper and lower sides of the moving groove 2. Two left-right penetrating holes 83 are formed in the left side top of the detection feet 82 along the up-down direction. A plurality of clamping grooves 84 are equidistantly formed on the outer ends of the front and back sides of the detection feet 82 along the up-down direction. The position of the infrared receiver plate 9 corresponds to the position of the detection feet 82. The detection feet 82 are the core execution components of the detection mechanism 8. The detection feet 82 can directly contact the road surface to detect the flatness and cross slope of the road surface. The first spring 85 is sleeved on the outer wall bottom of the detection feet 82. The top end of the first spring 85 is clamped to the bottom end of the sleeve plate 81. The bottom end of the first spring 85 is clamped to the outer wall bottom end of the detection feet 82. The first spring 85 is a rotary spring that elastically deforms after being extruded or stretched by external force and returns to the initial state after the external force is removed. During the detection process, the first spring 85 can maintain stable contact between the detection feet 82 and the road surface, while ensuring that the detection feet 82 can be smoothly reset after detection is completed. The roller 86 is rotatably arranged at the bottom end of the detection feet 82. During the detection process, the rolling of the roller 86 reduces the friction with the road surface, improving the smoothness and accuracy of the detection. The infrared sensor 813 is arranged on the inner side top of the detection feet 82. The infrared sensor 813 is located between the two penetration holes 83. The infrared receiver plate 9 and the infrared sensor 813 are matched. During the detection process, the infrared sensor 813 emits infrared signals in cooperation with the infrared receiver plate 9 to determine whether the flatness and cross slope of the road surface meet the requirements. The rotating roller 87 is four in number. The four rotating rollers 87 are divided into two groups, two by two. The front and back ends of the two groups of rotating rollers 87 are rotatably arranged on the outer side top of the two detection feet 82 through bearings along the up-down direction. The rotating rollers 87 are located between the two penetration holes 83. The outer wall back side of the rotating roller 87 is sleeved with a coil spring. One end of the coil spring is clamped to the outer wall of the rotating roller 87. The other end of the coil spring is clamped to the outer wall of the detection feet 82. The rotating roller 87 is used to wind the shielding cloth 88. The coil spring sleeved on the outer wall back side of the rotating roller 87 elastically deforms when the pull plate 89 moves, providing a rebound force to enable the shielding cloth 88 to be automatically wound after the pull plate 89 is released.The shielding cloth 88 is wound on the outer wall of the rotating roller 87, and the shielding cloth 88 is used to shield the infrared rays emitted by the infrared sensor 813, so as to prevent the infrared rays emitted by the infrared sensor 813 from penetrating through the penetrating hole 83. The number of the pull plates 89 is four, and the four pull plates 89 are divided into two groups, and the two groups of pull plates 89 are respectively slidably sleeved on the outer wall of the top of the two detection feet 82. The positions of the four pull plates 89 correspond to the positions of the four penetrating holes 83, respectively. The extrusion grooves 810 are formed on the front and back sides of the inner cavities of the pull plates 89, and the positions of the extrusion grooves 810 correspond to the positions of the clamping grooves 84. One end of each of the four shielding cloths 88 is arranged on the inner side of the four pull plates 89. The pull plates 89 are used to adjust the shielding range of the shielding cloth 88. By sliding the pull plates 89 up and down, the shielding cloth 88 can be stretched or retracted, so as to change the shielding state of the penetrating hole 83. The second spring 811 is embedded in the inner cavity of the extrusion groove 810. One end of the second spring 811 is clamped to the inner wall of the extrusion groove 810. The second spring 811 is a rotary spring, which is elastically deformed after being extruded or stretched by an external force, and returns to the initial state after the external force is removed. During the sliding process of the pull plate 89, the second spring 811 provides an elastic force, so that the clamping ball 812 can be smoothly embedded or separated from the clamping groove 84, realizing flexible adjustment and fixation of the pull plate 89. Part of the clamping ball 812 is embedded in the inner cavity of the extrusion groove 810, and the other part of the clamping ball 812 is inserted into the inner cavity of the clamping groove 84 corresponding to its position. The other end of the second spring 811 is clamped to the outer wall of the clamping ball 812. The position of the pull plate 89 can be fixed by the cooperation between the clamping ball 812 and the clamping groove 84. The length of the clamping ball 812 extending into the inner cavity of the clamping groove 84 is less than its radius, so that the pull plate 89 can slide up and down along the outer wall of the detection foot 82.

The motor 7 is screw-connected to the top right side of the cross beam 1. The top end of the connecting rod 4 located on the right side is locked on the output end of the motor 7 through a shaft coupling.

[0042] The working principle is as follows:

[0043] Step one, when the road crown transverse slope needs to be detected, the beam 1 is across the road surface, and the shaft of the dial 18 is in the same vertical plane with the middle line of the road, and the two feet 11 are placed on both sides of the road respectively, the two knobs 13 are rotated, the rotation force generated by the rotation of the knob 13 and the screw rod 10 cooperate to drive the foot 11 to move upwards along the outer wall of the screw rod 10, so as to promote the beam 1 to move downwards, until the two rollers 86 are in contact with the road surface, continue to rotate the knob 13, promote the beam 1 to continue to move downwards, the beam 1 moves downwards to drive the sleeve plate 81 to move downwards, at this time, the detection foot 82 is blocked by the road surface, when the sleeve plate 81 continues to move downwards, the first spring 85 is elastically deformed, until the beam 1 is adjusted to the appropriate height, the levelness of the beam 1 is determined by observing the dial 18, because the counterweight 19 is arranged at the bottom end of the inner cavity of the dial 18, under the action of gravity, the bottom end of the dial 18 is always perpendicular to the ground, and the inclination angle of the beam can be judged by observing the value of the scale line on the front side of the dial 18 corresponding to the top end of the indicating baffle 20 at this time, the beam 1 is not in the horizontal state, by rotating the knob 13 on one side of the beam 1, the rotation force generated by the rotation of the knob 13 and the screw rod 10 cooperate to drive the foot 11 to move up and down along the outer wall of the screw rod 10, until the beam 1 is adjusted to the horizontal state;

[0044] Step two, because the transverse slope of the road on both sides must be symmetrical, if it is not completely symmetrical, it will lead to poor drainage of the road, water will accumulate on the lower side, and will lead to unstable driving of vehicles, and may produce adverse consequences such as lateral slip, at this time, according to the allowable error range of the transverse slope of the road on both sides required by the construction, the positions of the four pull plates 89 are adjusted, by sliding the four pull plates 89 up and down, when the pull plate 89 slides along the outer wall of the detection foot 82, the inner wall of the clamping groove 84 can extrude the clamping ball 812 to move into the inner cavity of the extrusion groove 810, and extrude the second spring 811 to elastically deform, until the clamping ball 812 completely moves into the inner cavity of the extrusion groove 810, at the same time, when the pull plate 89 slides along the outer wall of the detection foot 82, the pull plate 89 can drive the rotating roller 87 to rotate by pulling the shielding cloth 88, and promote the elastic deformation of the coil spring sleeved on the outer wall of the rotating roller 87, until the pull plate 89 moves to the appropriate position, under the action of the elastic force of the second spring 811, the clamping ball 812 can be pushed into the inner cavity of the clamping groove 84 corresponding to its position, the cooperation between the clamping ball 812 and the clamping groove 84 can fix the position of the pull plate 89, at this time, the inner cavity of the through hole 83 between the two pull plates 89 on the outer wall of the same detection foot 82 is blocked by the shielding cloth 88, so that the infrared rays emitted by the infrared sensor 813 cannot pass through;

[0045] Step three, start infrared sensor 813, infrared receiving plate 9 and motor 7, at this time, because the cross beam 1 is in the horizontal state, so when the slope of the road arch transverse slope at the position of the two detection feet 82 is the same, the infrared rays emitted by the two infrared sensors 813 will respectively irradiate on the opposite infrared sensors 813, at this time, the infrared receiving plate 9 will not receive the infrared signal emitted by the infrared sensor 813, the output end of the motor 7 rotates, that is, the connecting rod 4 drives the chain wheel 5 to rotate, the chain wheel 5 rotates to promote the chain 6 to move circumferentially, because the two sleeve plates 81 are arranged on the front and rear sides of the chain 6, and then when the chain 6 moves circumferentially, it will promote the two sleeve plates 81 to move synchronously to the inside, because the slope of the transverse slope on both sides of the road exists, and then during the synchronous movement of the two detection feet 82 to the inside, the detection feet 82 will gradually move upward due to the slope, and the first spring 85 will be deformed, if the slope of the transverse slope on both sides of the road is different, with the movement of the two detection feet 82, when it moves to this position, it will cause the height of the two detection feet 82 to be different, if the error exceeds the range required by the use, it will cause the height of one detection foot 82 to be higher than that of the other detection foot 82, and then it will cause the infrared rays emitted by the two infrared sensors 813 to penetrate the inner cavity of the penetration hole 83 and irradiate on the two infrared receiving plates 9 respectively, when the infrared receiving plate 9 detects the infrared signal emitted by the infrared sensor 813, the motor 7 is turned off, at this time, the two detection feet 82 stop moving, and the position of the two detection feet 82 is the position where the slope of the transverse slope does not meet the construction requirements;

[0046] Step four, when the slope of the road slope needs to be detected, rotate the two knobs 13, and the knob 13 rotates to drive the supporting leg 11 to move downward along the outer wall of the screw rod 10, until the knob 13 cannot continue to rotate, at this time, the bottom ends of the two supporting legs 11 are in the same horizontal plane, place the device on the road slope, and the inclination angle of the cross beam can be judged by observing the numerical value of the scale line on the front side of the scale disc 18 corresponding to the top end of the indicating baffle 20, so that the slope of the road slope at this position can be detected, whether it meets the construction requirements can be judged, and the cross beam 1 is moved along the road slope by pulling the pull rod 21, that is, the slope of the road slope can be measured at multiple points;

[0047] Step five, when the road surface flatness needs to be detected, the motor 7 is started to drive the chain 6 to move circumferentially, so as to promote the two detection feet 82 to return to the initial position, the two knobs 13 are rotated, and the rotation force generated by the rotation of the knobs 13 and the screw rod 10 cooperate to drive the supporting feet 11 to move upwards along the outer wall of the screw rod 10, so as to promote the cross beam 1 to move downwards, the knobs 13 are continuously rotated to promote the cross beam 1 to continuously move downwards, the cross beam 1 moves downwards to drive the sleeve plate 81 to move downwards, at this time, the detection feet 82 are blocked by the road surface, when the sleeve plate 81 continuously moves downwards, the first spring 85 is elastically deformed to be extruded, until the cross beam 1 is adjusted to the appropriate height, and the cross beam 1 is in the horizontal state through the observation of the scale disc 18, the infrared sensor 813, the infrared receiving plate 9 and the pigment pump 15 are started, the four pull plates 89 are slid according to the error range allowed by the construction requirement of the road surface flatness, and then the above operation is repeated, until the pull plate 89 is adjusted to the appropriate position, the pull rod 21 is pulled to drive the cross beam 1 to move, with the movement of the cross beam 1, the two rollers 86 at the bottom of the two detection feet 82 roll along the road surface, when the detection foot 82 on the right side moves to the position where the road surface flatness does not meet the construction requirement, the detection foot 82 on the right side is promoted to move upwards or downwards, so that the infrared rays emitted by the two infrared sensors 813 pass through the inner cavity of the penetration hole 83 and irradiate on the two infrared receiving plates 9 respectively, when the infrared receiving plate 9 detects the infrared ray signal emitted by the infrared sensor 813, the pigment pump 15 and the automatic spray gun 16 are started, the pigment pump 15 pumps out the pigment in the inner cavity of the pigment box 14 and sprays it on the road surface at the detection foot 82 on the right side through the automatic spray gun 16, so that the road surface with unqualified flatness can be marked.

[0048] In summary, the device not only realizes the synchronous and efficient detection of the road crown transverse slope and the road surface flatness, but also improves the repair efficiency through the automatic marking function, and the unique design and working principle effectively solve the problems of single function, low efficiency and difficult to guarantee the precision in the prior art, and provide strong technical support for highway engineering construction and maintenance.
