Description

TECHNICAL FIELD

[0001] The utility model relates to intelligent detection technical field, concretely relates to a large area flatness construction intelligent detection device. BACKGROUND

[0002] It is known that flatness is an important means to measure the quality of construction. Through flatness measurement, uneven problems on the surface of the scale, such as concave or convex, can be found in time, so that appropriate measures are taken for repair, ensuring the measurement accuracy and stability of the scale, and further ensuring the accuracy of weighing. Flatness measurement can feedback problems in the production process, such as whether the process parameters are appropriate, whether the production line is running normally, etc., so as to guide the production process and improve the production efficiency and product quality. If the surface of the scale is uneven, it may lead to inaccurate weighing and affect the use effect. Through flatness measurement, the various performance of the scale can be ensured to meet the requirements.

[0003] For example, the Chinese patent document with the authorization announcement number CN118776494A, the announcement date CN118776494A, and the name "Floor flatness detection robot" includes a walking chassis and a detection device, and further includes a deformation mechanism and an angle sensor, a laser detector and a laser level meter arranged on the mechanism. The deformation mechanism is composed of two lengths of connecting rods connected by hinges to form a parallelogram, and the lower ends of the two short connecting rods of the deformation mechanism are provided with universal wheels; the angle sensor is arranged on one long rod of the deformation mechanism, and the deformation of the front and rear universal wheels of the deformation mechanism caused by the ground undulation changes the reading of the angle sensor; the laser detector and the laser level meter are used to set the reference level, which is the reference surface for floor measurement. The walking chassis drives the detection device to travel along the preset path, the angle sensor obtains the flatness data of the path, and the user can obtain the floor flatness data on the measured path according to the data measured by the angle sensor.

[0004] The existing technology has the disadvantages that the whole measured area is detected by the laser level meter and the angle measuring instrument in combination with the walking chassis, although the overall floor flatness can be measured, but the specific area of the uneven floor cannot be directly obtained.

DETAILED DESCRIPTION

[0034] In order to make the technical personnel of the prior art better understand the technical scheme of the present application, the present application will be further described in detail below with reference to the drawings.

[0035] In the description of the present application, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "degree", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate the orientation or positional relationship shown in the drawings, which is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, therefore it cannot be understood as a limitation of the present application.

[0036] Referring to Figures 1-10 The embodiment of the present application provides a large-area flatness construction intelligent detection device, which comprises a car body 1, a cross bar 2 and a vertical rod are hingedly arranged on the car body 1, pulleys are arranged on the vertical rod, and a marking assembly is arranged on the cross bar 2.

[0037] Specifically, the large-area flatness construction intelligent detection device includes a vehicle body 1, on which drive wheels 22 are installed. The vehicle body 1 is approximately an isosceles triangle, and the drive wheels 22 are arranged parallel to their base. A connecting part 10 is provided on the side wall at the apex of the vehicle body 1, and horizontal bars 2 and vertical bars are hinged to each other. Preferably, there are two vertical bars, namely a first vertical bar 3 and a second vertical bar 4. The connecting part 10 is fixed to the first vertical bar 3. Preferably, there are four horizontal bars 2, which are respectively hinged to the two sides of the first vertical bar 3 and the second vertical bar 4. The first vertical bar 3 and the second vertical bar 4 form a parallelogram structure with the horizontal bars 2. The bottom of the vertical rod 3 is fixedly connected to the first pulley 5, and the bottom of the second vertical rod 4 is fixedly connected to the second pulley 6. When the first pulley 5 and the second pulley 6 are on the same horizontal plane, the horizontal rod 2 remains horizontal. When the device is in operation, the drive wheel 22 drives the vehicle body 1 to travel along the set path, and drives the first pulley 5 and the second pulley 6 to rotate through the connecting part 10, thereby realizing the overall movement of the device. Since the two ends of the horizontal rod 2 are hinged to the first vertical rod 3 and the second vertical rod 4 respectively, when the ground 25 is uneven, the first pulley 5 will be higher or lower than the second pulley 6, causing the horizontal rod 2 to tilt. This is the prior art and will not be described in detail. One of the core innovations of this utility model embodiment is that a marking component is provided on the crossbar 2. The marking component includes a box 7, which is located in the middle of the crossbar 2. Marking dust 23 is provided inside the box 7. The marking dust 23 is preferably colored solid particles. A through hole 8 is provided inside the box 7. The through hole 8 is inclined and is used to connect the internal space and the external space of the box 7. Its outer surface is an arc surface. There are preferably two through holes 8, which are symmetrically arranged about the box 7. A blocking member 9 is fixedly connected to the first vertical bar 3 and the second vertical bar 4 respectively. When the crossbar 2 is horizontal, the blocking member 9 blocks the through hole 8, so that the marking dust 23 cannot fall through the through hole 8. Taking the through hole 8 near the second vertical bar 4 as an example, when the first pulley 5 is higher than the second pulley 6, the end of the crossbar 2 that is hinged to the first vertical bar 3 is higher than the end that is hinged to the second vertical bar 4 (i.e., at...). Figure 2 The middle horizontal bar 2 is tilted to the left. The orientation or positional relationship indicated by terms like "left" and "right" in this text is based on... Figure 2 (As shown in the orientation or positional relationship), it simultaneously drives the box 7 and the through hole 8 to tilt in the same direction, so that the blocking member 9 partially or no longer blocks the through hole 8. When the first pulley 5 is lower than the second pulley 6, the end of the horizontal bar 2 that is hinged to the first vertical bar 3 is lower than the end that is hinged to the second vertical bar 4 (i.e., the horizontal bar 2 tilts to the right), simultaneously driving the box 7 and the through hole 8 to tilt in the same direction, so that the blocking member 9 partially or no longer blocks the through hole 8, thereby marking the dust 23 falling to the ground 25 for marking. When the horizontal bar 2 returns to horizontal, the blocking member 9 re-blocks the through hole 8. This setting allows the marking dust 23 to mark the uneven ground 25 when the ground 25 traversed by the first pulley 5 and the second pulley 6 is uneven, so that the workers can directly observe or repair it.

[0038] Preferably, the inner wall of the box 7 is arranged obliquely. Specifically, the inner bottom of the box 7 is arranged obliquely, and the cross-sectional shape is approximately W-shaped, and the lowest point of the oblique surface is connected with the through hole 8. In this way, the marking dust 23 in the box 7 always falls along the inclined surface from the through hole 8, so as to avoid the marking dust 23 from gathering on the bottom surface and being unable to be used.

[0039] Further, a first power assembly for opening the through hole 8 is arranged between the horizontal rod 2 and the vertical rod. The power assembly includes a limiting rod 11 fixed to the vertical rod. Specifically, the first power assembly acts on the blocking piece 9 to expose the through hole 8 by the auxiliary blocking piece 9. The first power assembly is preferably the limiting rod 11, and there are preferably two limiting rods 11. The blocking piece 9 is fixed to the first vertical rod 3 and the second vertical rod 4 by the limiting rods 11, respectively. The end of the limiting rod 11 close to the blocking piece 9 is provided with an arc-shaped hole. When the first pulley 5 and the second pulley 6 are located in the same horizontal plane, the horizontal rod 2 remains horizontal, the blocking piece 9 abuts against the through hole 8, so that the marking dust 23 does not leak out. When the ground 25 is uneven, taking the limiting rod 11 close to the second vertical rod 4 as an example, when the first pulley 5 is higher than the second pulley 6, the second pulley 6 drives the limiting rod 11 and the blocking piece 9 to move downward. Since the horizontal rod 2 is hinged between the vertical rods, the end of the horizontal rod 2 connected with the first vertical rod 3 is lower than the end connected with the second vertical rod 4 (i.e., the horizontal rod 2 is inclined to the left), that is, the box 7 will rotate around the hinge shaft between the second vertical rod 4 and the horizontal rod 2 along with the horizontal rod 2. At this time, the through hole 8 and the blocking piece 9 will relatively rotate to expose the through hole 8. At this time, the marking dust 23 falls through the through hole 8 and marks the ground 25. (The blocking piece 9 on the opposite side and the through hole 8 will also relatively rotate to open the through hole 8 on the opposite side.) When the ground 25 is level, that is, when the first pulley 5 and the second pulley 6 are located in the same horizontal plane, the blocking piece 9 and the through hole 8 relatively rotate in the opposite direction to block the through hole 8. In this way, the passive opening and passive blocking of the through hole 8 are realized.

[0040] Further, an auxiliary powder outlet mechanism is arranged inside the through hole 8. Specifically, since the radial dimension of the through hole 8 is small, it is easy to be blocked. Therefore, the auxiliary powder outlet mechanism is arranged inside the through hole 8 to dredge the through hole 8, so that the marking dust 23 falls more smoothly from the through hole 8.

[0041] Preferably, the auxiliary powder outlet mechanism comprises a slide rod 12 slidingly arranged inside the through hole 8, and a plurality of protrusions 13 are arranged on the slide rod 12; and a second power assembly is arranged for driving the slide rod 12 to slide. Specifically, the slide rod 12 is slidingly arranged on the inner wall of the through hole 8, one side of the slide rod 12 is slidingly connected with the inner wall of the through hole 8, and a plurality of protrusions 13 are arranged on the other side of the slide rod 12; a second power assembly is arranged inside the through hole 8 for driving the slide rod 12 to slide, the second power assembly acts on the slide rod 12, and the second power assembly can be an existing reciprocating driving assembly such as an electric push rod, so that the slide rod 12 can slide along the through hole 8 towards the blocking piece 9, thereby driving the protrusions 13 to slide along the through hole 8, so that the protrusions 13 have a force on the marking dust 23 towards the blocking piece 9, the protrusions 13 will contact the marking dust 23, thereby pushing the dust towards the opening direction of the through hole 8, so as to avoid the marking dust 23 from being blocked inside the through hole 8.

[0042] Preferably, the second power assembly comprises a spring 15, a protrusion 14 is arranged on the slide rod 12, a sliding groove 16 is arranged on the inner wall of the through hole 8, and the spring 15 is arranged between the protrusion 14 and the sliding groove 16; and a wedge surface is arranged on the end of the slide rod 12. Specifically, the protrusion 14 is fixedly connected with the slide rod 12, and the slide rod 12 always slides along the through hole 8; the wedge surface is arranged on the slide rod 12 close to the direction of the blocking piece 9; the spring 15 is fixedly connected with the end of the sliding groove 16 close to the inside of the box body 7; when the horizontal rod 2 is kept horizontal, the blocking piece 9 blocks the through hole 8, at this time, the end of the slide rod 12 abuts against the blocking piece 9, and the spring 15 is in a stressed state; taking the spring 15 close to the direction of the second vertical rod 4 as an example, when the first pulley 5 is lower than the second pulley 6 in the horizontal direction, the through hole 8 is exposed, that is, the blocking piece 9 no longer abuts against the slide rod 12, the spring 15 is elastically released, and drives the slide rod 12 and the protrusions 13 to slide towards the direction of the blocking piece 9, so as to assist the marking dust 23 to be discharged; when the device passes through the horizontal ground 25, that is, the first pulley 5 and the second pulley 6 are located on the same horizontal plane, the second vertical rod 4 and the horizontal rod 2 restore the vertical state, that is, the blocking piece 9 and the through hole 8 will reversely rotate relative to each other, in this process, the blocking piece 9 applies a force to the wedge surface of the slide rod 12, so that the slide rod 12 moves along the through hole 8 towards the inside of the box body 7, and stores the power of the spring 15; the arrangement of the spring 15 provides power for the slide rod 12 to assist the powder discharge, and provides power for the slide rod 12 to return, so as to facilitate the device to repeatedly mark.

[0043] When the marking dust 23 in the box 7 is consumed, in order to supplement the marking dust 23, the box 7 is provided with a cover plate 17, and the cover plate 17 is provided with a hand-held part 18. Specifically, the box 7 is provided with a powder adding port on the top surface, the cover plate 17 is arranged on the powder adding port and is matched with the powder adding port in diameter, the cover plate 17 is provided with the hand-held part 18 on the upper surface, the hand-held part 18 is approximately cylindrical, and the powder adding port can be opened or blocked by the cover plate 17 through the hand-held part 18 before the device is operated according to different working environments, so as to facilitate the addition of the marking dust 23.

[0044] In order to obtain an accurate flatness measurement curve, the vehicle body 1 is provided with a laser scanner 19, and a telescopic rod 20 is arranged between the laser scanner 19 and the vehicle body 1. Specifically, the telescopic rod 20 is arranged on the upper surface of the vehicle body 1, and the laser scanner 19 is arranged on the telescopic rod 20. The laser scanner 19 scans the ground 25 to be measured when the vehicle body 1 is running, and generates a flatness measurement curve according to the running route through the reflection of laser. The telescopic rod 20 can automatically adjust the height to adapt to different working environments and working requirements.

[0045] In order to keep the laser scanner 19 stable, a gyroscope 21 is arranged between the laser scanner 19 and the telescopic rod 20. The gyroscope 21 is located between the telescopic rod 20 and the laser scanner 19. When the vehicle body 1 encounters uneven ground 25 or bumps caused by gravel during running, the laser scanner 19 may vibrate to cause inaccurate measurement results. The gyroscope 21 is used to keep the laser scanner 19 stable, and increases the accuracy of the measurement results.

[0046] The above only describes certain exemplary embodiments of the present application by way of illustration, and it is needless to say that the described embodiments can be modified in various ways without departing from the spirit and scope of the present application for those skilled in the art. Therefore, the above drawings and descriptions are illustrative in nature and should not be understood as limiting the scope of protection of the claims of the present application.
