Detailed Description
Embodiments of the application are described in detail below with reference to fig. 1-9, but the application can be implemented in a number of different ways, which are defined and covered by the claims.
The embodiment of the application discloses road flatness surveying equipment, which is mainly applied to the process of surveying the flatness of a road surface, can survey the flatness of the whole road section in technical effect, can survey the pits and the projections of the road surface in the process of moving along the road surface, and can effectively improve the surveying efficiency; particularly, in the surveying process, pigments with different colors can be sprayed on the convex parts and the periphery of the concave parts of the pavement in an automatic marking mode, so that the concave parts and the convex parts of the pavement can be conveniently and rapidly distinguished, and further, the situation that the uneven parts of the pavement cannot be identified and cannot be timely trimmed is prevented; furthermore, the road flatness surveying equipment can also adjust the surveying precision, so that the road flatness surveying equipment can survey road sections with different surveying requirements.
Embodiment one:
referring to fig. 1, a road flatness investigation apparatus comprises two parallel arranged support frames 1, wherein a movable wheel 3 is arranged on the support frames 1 through a balance adjusting part 2, a investigation part 4 is arranged between the two support frames 1, and the balance adjusting part 2 comprises a height measuring ruler 21 arranged on the opposite sides of the support frames 1.
In practical application, firstly, the application is moved to the road surface to be surveyed, the moving wheels 3 are positioned at two sides of the road, and then the application is regulated by the balance regulating component 2, so that the support frame 1 is parallel to the road surface; the application is then pushed along the road section during which the flatness of the road surface is surveyed by the surveying element 4.
Referring to fig. 1 and 2, since the road surface of the uphill or downhill road has a corresponding inclination, when the application performs flatness investigation on the inclined road surface, the support frame 1 needs to be kept parallel to the road surface so as to improve the investigation accuracy of the application on the road surface; based on the above, the application provides a balance adjusting component 2, in particular, the balance adjusting component 2 further comprises a rotating ball 22, a plurality of rotating balls 22 are connected inside the support frame 1 at equal intervals along the length direction of the rotating ball, through holes which are longitudinally distributed are formed in the rotating ball 22 in a penetrating way, threaded rods 23 are arranged in the through holes in a threaded connection way, the plurality of threaded rods 23 are connected through belts, and through the arrangement of the belts, one threaded rod 23 can drive other threaded rods 23 on the same support frame 1 to synchronously rotate; a stabilizing rod 24 is rotatably connected between two opposite threaded rods 23 on the two support frames 1, and the threaded rods 23 can be ensured to be always in a vertical state through the stabilizing rod 24; the lower end of the threaded rod 23 is connected with the moving wheel 3.
It should be noted that the diameter of the rotating ball 22 is larger than the thickness of the supporting frame 1, the upper and lower sides of the rotating ball 22 extend to the outside after passing through the supporting frame 1, and the rotating ball 22 can rotate at will inside the supporting frame 1.
In the specific implementation process, the threaded rod 23 on any support frame 1 is rotated, and as the moving wheel 3 is always abutted on the road surface, when the threaded rod 23 is rotated, the threaded rod 23 can drive the rotating ball 22 and the support frame 1 to move up and down through the cooperation between the threaded rod 23 and the rotating ball 22; then, whether the distance between the corners of the two support frames 1 and the road surface is consistent is observed through the height measuring ruler 21, so that whether the two support frames are parallel to the road surface is judged; therefore, the application is convenient for carrying out flatness survey on the whole road section when pushing along the road surface, and prevents deviation of the survey result caused by the fact that the support frame 1 is not parallel to the road surface, thereby improving the survey precision.
The moving track of the movable wheel 3 at the lower end of the other support frame 1 is used as a circle center to do small-amplitude circular movement when the height of any support frame 1 is adjusted; therefore, the threaded rod 23 inside the support frame 1 with the height adjusted and the moving wheel 3 at the lower end thereof can incline, and the threaded rod 23 is no longer in a vertical state; the stress points of the movable wheels 3 are offset, so that the service life of the movable wheels 3 is influenced, and the movable wheels 3 in an inclined state easily cause resistance to influence the smoothness of the road surface pushing device.
Based on this, a degree of freedom can be provided to the threaded rod 23 by the turning ball 22, and when the threaded rod 23 is turned to cause the support frame 1 to move up and down, the turning ball 22 turns inside the support frame 1; at this time, the threaded rod 23 is not affected by the supporting frame 1 and still is in a vertical state, and the stress point of the moving wheel 3 is unchanged, so that the moving wheel 3 is ensured not to cause resistance in the process of pushing the application along the road section.
Referring to fig. 3 and 4, the evenness of the road surface is surveyed, that is, whether the surveyed road surface has concave or convex, and in order to avoid the surveyed omission, it is generally necessary to surveyed a plurality of places and even the whole road section of the road surface, so that the surveyed efficiency is critical; based on this, the present application provides a surveying unit 4 for accelerating surveying efficiency, in particular, the surveying unit 4 includes a support plate 41, two support plates 41 are symmetrically disposed on opposite sides of two support frames 1 along a length direction thereof, a pre-adjusting assembly 42 is mounted on the support plate 41, the pre-adjusting assembly 42 includes a plurality of connection plates 421 positioned below the support plate 41, an execution table 44 is mounted at a lower end of the connection plates 421 through support elastic members 43, a surveying ball 45 is rotatably connected to a lower end of the execution table 44, a marking assembly 46 is mounted between the execution table 44 and the connection plates 421, and the marking assembly 46 includes a high pressure nozzle 461 disposed at a bottom of the execution table 44.
In this embodiment, the supporting elastic member 43 always applies a pushing force to the execution table 44 directed away from the connecting plate 421, so that the execution table 44 drives the surveying ball 45 to roll against the road surface in the initial state.
In the specific implementation process, the supporting frame 1 is pushed, the supporting frame 1 drives the moving wheel 3 to move along the surveying section, the supporting frame 1 drives the bearing plate 41, the connecting plate 421, the supporting elastic piece 43, the executing table 44 and the surveying ball 45 to integrally move, and during this period, the flatness of the road surface is surveyed through the surveying ball 45.
When the surveying ball 45 surveys the depression of the road surface, the executive desk 44 drives the surveying ball 45 to roll into the depression of the road surface under the action of the supporting elastic piece 43; when the surveying ball 45 surveys the raised place of the road surface, the surveying ball 45 drives the execution table 44 to move upwards under the action of the raised place of the road surface; therefore, the concave and convex of the pavement can be detected through the surveying ball 45 in the process of moving along the pavement, and the surveying efficiency can be effectively improved.
In addition, the executing platform 44 can respectively and quickly mark the periphery of the concave position or the convex position of the pavement during the descending and the ascending processes through the marking component 46; therefore, the uneven part of the road surface can be conveniently and quickly identified in the later stage through the marking of the road surface, and further, the road surface can be conveniently and quickly trimmed by workers.
With continued reference to fig. 3 and 4, before the flatness of the road surface is surveyed, in order to facilitate the surveying ball 45 to more accurately survey the depressions and projections of the road surface, the height of the surveying ball 45 needs to be adjusted, specifically, the pre-adjusting assembly 42 further includes a plurality of adjusting screws 422, the supporting plate 41 is threaded and passes through the plurality of adjusting screws 422 at equal intervals along the length direction thereof, the plurality of adjusting screws 422 are connected by belt transmission, the lower ends of the adjusting screws 422 are rotatably connected with the upper ends of the connecting plates 421, and two telescopic rods 423 are symmetrically arranged on opposite sides of the connecting plates 421 and the supporting plate 41 along the adjusting screws 422; the connecting plate 421 can be limited by the telescopic rod 423, so that the connecting plate 421 can only move up and down when the adjusting screw 422 is rotated.
In the initial state, the distance between the connecting plate 421 and the bearing plate 41 is the smallest, and even if the execution table 44 drives the surveying ball 45 to be at the lowest position under the action of the supporting elastic piece 43, the surveying ball 45 cannot be contacted with the road surface, so that the surveying ball is convenient to move to the road surface to be surveyed; in addition, the distance between the connection plate 421 and the actuating stage 44 at this time is maximized by the supporting elastic member 43.
In the implementation process, in order to ensure that the surveying ball 45 moves downwards when surveying the concave part of the road surface and to facilitate the surveying ball 45 to move upwards when surveying the convex part of the road surface, the supporting elastic member 43 needs to maintain a certain elasticity; at this time, the adjusting screw 422 is rotated, the connecting plate 421 is driven to move upwards or downwards while the adjusting screw 422 rotates, and the execution table 44 can drive the surveying balls 45 to move synchronously and roll and contact with the road surface by adjusting the position of the connecting plate 421; the distance between the connecting plate 421 and the execution table 44 is relatively reduced, and the supporting elastic member 43 is correspondingly contracted, but the supporting elastic member 43 is not contracted to the shortest and has elasticity at this time; thus facilitating the surveying of the depressions and projections of the road surface by the cooperation between the connection plate 421, the supporting elastic member 43, the execution table 44 and the survey balls 45.
Referring to fig. 4 and 5, in this embodiment, after the concave and convex positions of the road surface are detected, corresponding marks can be performed on the uneven positions of the road surface, and the marks at the concave positions and the convex positions have different colors, so that the uneven positions of the road surface can be conveniently and quickly identified in the later stage, specifically, the marking assembly 46 further includes a first cavity 462 and a second cavity 463 which are formed inside the execution table 44, the second cavity 463 is located outside the first cavity 462 and is not communicated with each other, the bottoms of the first cavity 462 and the second cavity 463 are respectively provided with a plurality of high-pressure nozzles 461 distributed in a ring shape, and the inner bottom walls of the first cavity 462 and the second cavity 463 are both V-shaped structures for conveniently collecting pigments; the V-shaped structure is convenient for inducing the pigment in the high-pressure spray head 461 to the upper part, thereby facilitating the pigment taking of the high-pressure spray head 461.
Further, in this embodiment, two feeding hoppers are symmetrically disposed at the upper end of the execution table 44 along the axis thereof, a conduit 464 is mounted at the lower end of any feeding hopper, the lower end of the conduit 464 sequentially passes through the execution table 44 and the second cavity 463 and then extends into the first cavity 462, and a feeding inlet 465 which is communicated with the other feeding hopper is formed in the upper side wall of the second cavity 463.
In a specific implementation process, marking pigments with different colors are respectively injected into the first cavity 462 and the second cavity 463 through the guide pipe 464 and the feeding port 465; when the survey ball 45 surveys the depression of the road surface, pigment is sprayed around the depression of the road surface through the high-pressure spray head 461 at the bottom of the first cavity 462; when the survey ball 45 surveys the protrusion of the road surface, pigment is sprayed around the protrusion of the road surface through the high-pressure spray head 461 at the bottom of the second chamber 463; and pigment colors of the concave part and the convex part are different, so that the concave part and the convex part of the road surface can be conveniently and rapidly distinguished, and further, the situation that the uneven part of the road surface cannot be identified and the road surface cannot be timely trimmed is prevented.
Embodiment two:
referring to fig. 4, 5, 6 and 7, in order to improve the surveying efficiency, in the first embodiment, the pigment inside the first cavity 462 and the second cavity 463 may be automatically ejected; specifically, the marking assembly 46 further includes two circular grooves formed inside the upper side of the execution table 44 and symmetrically arranged along the axis thereof, two positioning rods 466 corresponding to the positions of the circular grooves are mounted at the lower end of the connecting plate 421, the lower ends of the positioning rods 466 extend into the circular grooves and are provided with a linkage plate 467, the upper side wall and the lower side wall of the linkage plate 467 are symmetrically provided with two touch switches 468 along the axis thereof, and the upper side wall and the lower side wall of the circular groove are respectively provided with an annular conductive plate 469 matched with the touch switches 468.
In the implementation process, when the surveying ball 45 surveys the protrusion or depression of the road surface to drive the execution table 44 to move up and down, the positioning rod 466 and the linkage plate 467 are both in a fixed state because the positioning rod 466 is connected with the connecting plate 421, so that the execution table 44 and the linkage plate 467 move relatively.
When the protrusion of the road surface is detected, the surveying ball 45 drives the execution table 44 to move upwards, the touch switch 468 at the lower end of the linkage plate 467 is contacted with the annular conductive plate 469 at the bottom wall in the circular groove, and at the moment, the high-pressure spray head 461 at the bottom of the second cavity 463 is controlled to spray pigment around the protrusion of the road surface through the touch switch 468; conversely, when the depression of the road surface is detected, the surveying ball 45 drives the execution table 44 to move downwards, the touch switch 468 at the upper end of the linkage plate 467 is in contact with the annular conductive plate 469 (shown in fig. 6 and 7) at the top wall of the circular groove, and at this time, the high-pressure spray head 461 at the bottom of the first cavity 462 is controlled to spray pigment around the depression of the road surface by the touch switch 468; therefore, the high-pressure spray head 461 can automatically mark the uneven part of the road surface without manual operation.
It should be further noted that, in fig. 6, the hatched portion below the reconnaissance ball 45 is a road surface, and a recess is above the road surface.
Referring to fig. 8 and 9, since the survey standards are different for different road segments, smaller depressions or protrusions also need to be trimmed for the road surface where the survey requirements are higher; the road surface with lower surveying requirement, such as a road section with lower running speed of an automobile, can be not trimmed under the condition that smaller concave or convex is not influenced, and the surveying precision of the road surface is required to be controlled by controlling the sensitivity of the touch switch 468; specific:

The pushing spring 470 always applies a pushing force to the touch switch 468 toward a side away from the receiving slot, so that the distance between the touch switch 468 and the annular conductive plate 469 is minimized by the pushing force.
Further, in the present embodiment, a longitudinal sliding groove 473 is formed inside the positioning rod 466, a pushing post 474 is slidably connected inside the longitudinal sliding groove 473, a return spring 475 is installed between the pushing post 474 and an inner top wall of the longitudinal sliding groove 473, two pull ropes 476 corresponding to the positions of the pull plates 471 are symmetrically arranged at the lower end of the pushing post 474 along the axis of the pushing post 474, and one end of the pull rope 476, which is far away from the pushing post 474, sequentially passes through the positioning rod 466 and the linkage plate 467 and then is connected with the pull plate 471 corresponding to the positions of the pull ropes; the return spring 475 always applies an upward contraction force to the pressing post 474 such that the pressing post 474 is located at the upper side of the longitudinal slide groove 473 in the initial state.
In the specific implementation process, the pushing and pressing column 474 is pushed to move up and down along the longitudinal sliding groove 473, and when the pushing and pressing column 474 moves upwards, the pulling and pressing column 476 moves the pulling and pressing plate 471 to one side close to the axis of the linkage plate 467; the pulling plate 471 applies a pulling force greater than the elasticity of the pushing spring 470 to the touch switch 468 through the tightening rope 472, so that the touch switch 468 is contracted towards the accommodating groove under the action of the pulling force, and at the moment, the distance between the touch switch 468 and the annular conductive plate 469 is increased, so that the sensitivity of the touch switch 468 is reduced; the touch switch 468 will only contact the annular conductive plate 469 when the survey ball 45 surveys a large depression or protrusion; and is suitable for road surfaces with lower requirements for surveying.
When the pushing post 474 moves downwards, the pulling force exerted by the pulling rope 476 on the pulling plate 471 is reduced, the touch switch 468 moves to a side far away from the accommodating groove under the action of the pushing spring 470, at this time, the distance between the touch switch 468 and the annular conductive plate 469 is increased, and the sensitivity of the touch switch 468 is further improved; the touch switch 468 is in contact with the annular conductive plate 469 when the survey ball 45 surveys smaller depressions or projections; the method is suitable for road surfaces with higher surveying requirements, and the surveying precision is correspondingly improved.
In summary, in the present embodiment, the sensitivity of the touch switch 468 can be controlled by adjusting the distance between the touch switch 468 and the annular conductive plate 469, so that the accuracy of the road surface surveying can be further controlled, and the road surface surveying can be performed on road sections with different surveying requirements.
In addition, in the present embodiment, in order to ensure that the distance between the touch switch 468 and the annular conductive plate 469 does not change after adjustment, it is necessary to perform limit fixation after the push post 474 moves along the longitudinal sliding groove 473; specifically, a communicating hole is formed in one side of the longitudinal sliding groove 473 away from the axis of the execution table 44 in a penetrating manner, an operating rod 477 which is connected in the communicating hole in a sliding manner is mounted on the outer wall of the pushing post 474, and a plurality of limiting grooves 478 matched with the operating rod 477 are formed in any side wall of the communicating hole from top to bottom at equal intervals.
In practical application, the push column 474 is pushed by the operating rod 477 to move along the longitudinal sliding groove 473, then the operating rod 477 is pushed into the limiting groove 478, and the contraction force applied to the push column 474 by the return spring 475 can be counteracted by the cooperation between the operating rod 477 and the limiting groove 478, so that the push column 474 is prevented from moving randomly in the longitudinal sliding groove 473, and the distance between the touch switch 468 and the annular conductive plate 469 is prevented from changing, so that the touch switch 468 is limited and fixed.
When in operation, the device comprises: the first step: firstly, marking pigments with different colors are respectively injected into the first cavity 462 and the second cavity 463 through a conduit 464 and a feed inlet 465; secondly, moving the application to the road surface to be surveyed, then rotating the threaded rod 23 on any support frame 1, wherein the threaded rod 23 can drive the rotating ball 22 and the support frame 1 to move up and down through the cooperation between the threaded rod 23 and the rotating ball 22; then, it is observed whether the distance between the corners of the two support frames 1 and the road surface is uniform or not by the height measuring scale 21, so that the support frames 1 are kept parallel to the road surface.
And a second step of: the adjusting screw 422 is rotated, the connecting plate 421 is driven to move upwards or downwards while the adjusting screw 422 rotates, and the executing table 44 can drive the surveying balls 45 to move synchronously and roll and contact with the road surface by adjusting the position of the connecting plate 421; the distance between the connection plate 421 and the actuating table 44 is relatively reduced, and the supporting elastic member 43 is correspondingly contracted, but the supporting elastic member 43 is not contracted to the shortest and has elasticity at this time.
And a third step of: pushing the pushing post 474 to move up and down along the longitudinal sliding groove 473, when the pushing post 474 moves up, applying a tension force greater than the elasticity of the pushing spring 470 to the touch switch 468 by the pull rope 476, the pull plate 471 and the tightening rope 472, so that the touch switch 468 contracts into the accommodating groove, and at this time, the distance between the touch switch 468 and the annular conductive plate 469 increases, thereby reducing the sensitivity of the touch switch 468; the touch switch 468 will only contact the annular conductive plate 469 when the survey ball 45 surveys a large depression or protrusion; and is suitable for road surfaces with lower requirements for surveying.
When the pushing post 474 moves downward, the pulling force exerted by the pulling rope 476 on the pulling plate 471 is reduced, the distance between the touch switch 468 and the annular conductive plate 469 is increased under the action of the pushing spring 470, and the sensitivity of the touch switch 468 is further improved; the touch switch 468 is in contact with the annular conductive plate 469 when the survey ball 45 surveys smaller depressions or projections; the method is suitable for road surfaces with higher surveying requirements, and the surveying precision is correspondingly improved.
Fourth step: pushing the supporting frame 1 to move along a surveying road section, wherein the supporting frame 1 drives the supporting plate 41, the connecting plate 421, the supporting elastic piece 43, the execution table 44 and the surveying balls 45 to integrally move, and during the period, the flatness of the road surface is surveyed through the surveying balls 45; when the surveying ball 45 surveys the protrusion or depression of the road surface to drive the execution table 44 to move up and down, the positioning rod 466 and the linkage plate 467 are in a fixed state because the positioning rod 466 is connected with the connecting plate 421, so that the execution table 44 and the linkage plate 467 move relatively;
when the surveying ball 45 surveys the depression of the road surface, the execution table 44 drives the surveying ball 45 to roll into the depression of the road surface under the action of the supporting elastic piece 43, the surveying ball 45 drives the execution table 44 to move downwards, the touch switch 468 at the upper end of the linkage plate 467 is contacted with the annular conductive plate 469 at the inner top wall of the circular groove, and at the moment, the high-pressure spray head 461 at the bottom of the first cavity 462 is controlled by the touch switch 468 to spray pigment around the depression of the road surface;
when the surveying ball 45 surveys the raised position of the pavement, the surveying ball 45 drives the execution table 44 to move upwards under the action of the raised position of the pavement, the touch switch 468 at the lower end of the linkage plate 467 is contacted with the annular conductive plate 469 at the bottom wall in the circular groove, and at the moment, the high-pressure spray head 461 at the bottom of the second cavity 463 is controlled to spray pigment around the raised position of the pavement through the touch switch 468;
therefore, the high-pressure spray head 461 can automatically mark the uneven part of the road surface without manual operation; and the uneven part of the road surface is convenient to quickly identify in the later stage through the marking of the road surface, so that the road surface can be quickly trimmed by workers.
