Description

Technical Field

[0001] The present application relates to the technical field of building construction, and in particular to a device for detecting the flatness of a building project. Background Art

[0002] At present, construction projects mainly involve the construction of houses and buildings. After the construction of houses and buildings is completed, the quality needs to be tested, which includes the detection of the flatness inside the house, and fully testing the flatness of the indoor surface. Flatness refers to the deviation of the macroscopic concave and convex height of the substrate from the ideal plane. The tolerance zone is the area between two parallel planes with a distance equal to the tolerance value. Flatness belongs to the shape error among the form and position errors.

[0003] There are the following methods for measuring flatness: 1. Feeler gauge measurement method. Feeler gauges are mainly used to measure gap spacing, and can only perform rough measurements on flatness. Dirt and dust on the feeler gauge and workpiece must be removed before use. When using, one or several pieces can be overlapped and inserted into the gap to feel a slight drag. The action should be gentle during measurement, and hard insertion is not allowed. Due to its low accuracy, low detection efficiency, and incomplete results, only the edges of parts can be detected. 2. Liquid plane method. The liquid plane method uses the liquid plane as the measurement reference plane. The liquid plane is composed of the liquid surface in the "connecting tank", and then measured with a sensor. Based on the working principle of the communicating vessel, it is suitable for measuring the flatness of large continuous or discontinuous planes, but the measurement time is long and it is sensitive to temperature. It is only suitable for planes with low measurement accuracy.

[0004] The only method suitable for detecting the vertical flatness of the wall is the feeler gauge measurement method, but this measurement method requires measuring the wall bit by bit, which is inefficient. Summary of the invention

[0005] In order to improve measurement efficiency, the present application provides a construction engineering flatness detection device.

[0006] The above-mentioned purpose of the present application is achieved through the following technical solutions:

[0007] The detection assembly comprises a plurality of detection sleeves which are arranged horizontally and vertically point to the end face of the wall to be detected, and a detection slide rod which is slidably inserted into each of the detection sleeves. The detection sleeve has sliding holes at both ends through which the detection slide rods are inserted. The detection sleeve has a compression spring in the sliding hole which pushes one end of the detection slide rod against the end face of the wall to be detected. A walking ball is rotatably embedded in the end of the detection slide rod close to the end face of the wall to be detected. The detection slide rod is protruding from the two ends of the detection sleeve and is provided with detection scales along the length direction. The detection scales gradually increase toward the two ends along the length direction of the detection slide rod. The detection support platform slides parallel to the end face of the wall to be detected.

[0008] By adopting the above technical solution, when the vertical end face of the wall is inspected by the flatness detection device of the construction project, the detection support platform is first moved to one side of the wall so that the detection support frame is parallel to the wall. At this time, the running ball at one end of the detection slide bar abuts against the wall, so that the position marked with the center value of the detection scale is aligned with the end of the detection sleeve. Then the detection support frame is moved vertically so that the detection slide bar abuts against the wall and moves. During the movement, observe whether the detection slide bar slips relative to the detection sleeve. If slippage occurs, the detection scale corresponding to the end face of the corresponding detection sleeve can be observed. If the value is large, it can be marked and recorded. After inspecting a part of the wall from bottom to top, the detection support platform is moved parallel to the wall, so as to inspect the other parts of the wall in turn. This solution makes the area of ​​the wall that can be inspected at a time larger, and the inspection is more convenient, thereby effectively improving the inspection efficiency.

[0009] Preferably, an observation detection tube is provided on the side of the detection support frame away from the end face of the wall to be detected, and the observation detection tube includes a first pipe arranged vertically and a second pipe arranged horizontally at the lower end of the first pipe and connected to the first pipe, a first reflective lens is obliquely arranged at the internal connection between the first pipe and the second pipe, the top of the first pipe is located at the lower end of the detection slide bar and aligned with the detection scale, and the middle part of the first pipe is telescopically arranged.

[0010] By adopting the above technical solution, when the detection support frame moves vertically upward to detect the upper position of the wall end face, it may be difficult to see clearly the indication of the detection slide bar being aligned with the end face of the detection sleeve. In this solution, an observation detection tube is set up so that the operator can observe the first reflective lens inside the second pipe. The first reflective lens can reflect the detection scale of the alignment of the first pipe, so that the operator can read the detection scale of the alignment detection sleeve through horizontal observation, which is more convenient. At the same time, the middle part of the first pipe can be retracted to adapt to the vertical movement of the detection support frame.

[0011] Preferably, a marking wheel for marking the end face of the wall to be inspected is slidably provided at the lower end of each detection sleeve at one end close to the end face of the wall to be inspected, and the marking wheel includes a wheel frame and a wheel body rotatably provided on the wheel frame; a marking cylinder for pushing the wheel frame to move toward the end face of the wall to be inspected is provided at the lower end of the detection sleeve at the side of the wheel frame away from the end face of the wall to be inspected, and a set of marking numbers from 1 to 5 are circumferentially provided around the side end of the wheel body.

[0012] By adopting the above technical solution, the flatness deviation of the wall is usually 1mm-3mm. Once it exceeds 5mm, it can be directly observed by the naked eye. Marking numbers 1-5 are set on the circumferential side of the wheel body. When the unevenness is detected by the detection slide bar and the approximate deviation is known, the wheel body is rotated so that the marking number corresponding to the deviation is aligned with the wall. Then, the wheel frame is driven to move to one side of the wall by the marking cylinder, so that the wheel body prints a mark on the wall, which is convenient for subsequent statistics and recording of uneven positions. At the same time, a marking wheel is set on the lower side of each detection set, so that the indication at the wheel body mark is the deviation of the end face of the wall on the upper side of the indication, making the marking position more accurate.

[0013] Preferably, a passive gear coaxially connected to the marking wheel and driving the marking wheel to rotate is rotatably provided at one end of the wheel frame, a driving gear meshing with the passive gear is rotatably provided at the lower end of the detection sleeve on the side of the passive gear away from the wall to be detected, an adjustment cylinder is arranged parallel to one side of the marking cylinder, and an adjustment rack meshing with the driving gear is arranged on the piston rod of the adjustment cylinder.

[0014] By adopting the above technical solution, the adjusting rack is driven to move by the adjusting cylinder, the active gear is driven to rotate by the adjusting rack, and the marking cylinder drives the marking wheel to move until the passive gear is engaged with the active gear, so that when the active gear rotates, the passive gear can be driven to rotate, thereby realizing the rotating wheel body to achieve the purpose of adjusting the number, and then the marking cylinder can drive the marking wheel to mark the wall, thereby facilitating the marking of the high wall after the detection support frame moves vertically upward.

[0015] Preferably, two sets of marking numbers are provided on the lateral ends of the wheel body, and the same marking numbers are symmetrical about the axis of the wheel body. An observation and control tube is provided on the lower side of the marking cylinder, which is aimed at the end face of the wheel body to be inspected away from the wall, and the other end of the observation and control tube extends to the upper side of the detection support platform.

[0016] By adopting the above technical solution, two sets of marking numbers are provided on the lateral ends of the wheel body, and the two sets of marking numbers are connected end to end, so that the two marking numbers symmetrical with the axis of the wheel body are the same number. By observing the control tube on the detection support platform, the marking number at the end of the wheel body away from the wall can be directly observed. The marking number is the same as the marking number at the end of the wheel body facing the wall, which makes it more convenient and accurate to adjust the marking number.

[0017] Preferably, the observation and control tube includes a third pipe horizontally fixed to the lower end of the marking cylinder, a fourth pipe vertically connected to the end of the third pipe away from the wheel body, and a fifth pipe horizontally connected to the lower end of the fourth pipe, the inner walls of the connection between the third pipe and the fourth pipe and the inner walls of the connection between the fourth pipe and the fifth pipe are both inclinedly provided with second reflective lenses, the two second reflective lenses are parallel to each other, and the middle part of the fourth pipe is telescopically arranged.

[0018] By adopting the above technical solution, the marked numbers on the wheel body are reflected twice by two second reflecting lenses, so that the operator can observe the marked numbers directly by observing the inside of the fifth pipe. At the same time, the middle part of the fourth pipe can be extended and retracted, so that the detection support frame will not affect the normal observation of the control pipe when it moves vertically upward, which is more convenient.

[0019] Preferably, a warning bracket is provided at the lower end of the detection sleeve on a side away from the end face of the wall to be detected, and the warning bracket is rotatably connected to a warning support plate through a torsion spring. The warning support plate is pressed against the end of the detection slide bar away from the walking ball through the torsion spring, and the warning bracket is provided with trigger plates for the warning support plate to touch on both sides of the warning support plate close to and away from the end face of the wall to be detected, respectively, and a warning light is provided at the lower end of the warning bracket, which lights up when the warning support plate touches the trigger plate.

[0020] By adopting the above technical scheme, multiple detection slide bars are arranged in parallel. Once a detection slide bar is not observed after sliding, the flatness of the wall at that place will not be detected as a whole. In this scheme, a warning bracket is arranged at the lower end of the detection sleeve. The warning bracket is connected to the warning support plate through a torsion spring and abuts against one end of the detection slide bar. When the detection slide bar slides, one end of the warning support plate continues to abut against the detection slide bar, causing the warning support plate to rotate. The rotating warning support plate will abut against the contact power generation plate, thereby lighting up the corresponding warning light. At this time, the operator can directly observe which detection slide bar has slipped, thereby reducing the probability of missed detection and being more convenient.

[0021] Preferably, an adjusting platform is provided at the upper end of the detection support platform, and a plurality of connecting columns inserted into the interior of the detection support platform are vertically provided at the lower end of the adjusting platform. An adjusting bolt that abuts against the upper end surface of the detection support platform is vertically penetrated by threads near the corners on the upper end surface of the adjusting platform, and two mutually perpendicular levels are horizontally embedded in the middle of the upper end surface of the adjusting platform.

[0022] By adopting the above technical solution, the adjustment platform is connected to the detection support platform through the connecting column, and the height of the corners of the adjustment platform is adjusted by rotating the adjusting bolts around it. Then, by observing the two spirit levels, the entire adjustment platform can be adjusted to a horizontal state, thereby ensuring the accuracy of subsequent measurements.

[0023] Preferably, two lifting cylinders are vertically arranged on the upper end surface of the adjustment platform, and the two ends of the detection support frame are fixed to the top of the piston rods of the two lifting cylinders.

[0024] By adopting the above technical solution, the detection support frame can be stably and evenly lifted by the lifting cylinder, so that the detection component can be measured more accurately and precisely.

[0025] Preferably, a guide track parallel to the wall and adsorbed on the wall is provided on the side of the detection support platform close to the end face of the wall to be detected, a guide groove is provided on the upper side end of the guide track, and a row of guide rollers embedded in the guide groove and rolling and sliding along the length direction of the guide groove are rotatably provided on the side end of the detection support platform close to the wall.

[0026] By adopting the above technical solution, the guide track is adsorbed on the wall parallel to the wall, and then the guide roller on the detection support platform is slid into the guide groove of the guide track, so that the detection support platform can slide parallel to the wall, thereby ensuring the distance between the detection support platform and the wall during detection, while improving the detection efficiency.

[0027] In summary, the beneficial technical effects of this application are:

[0028] 1. When the vertical end face of the wall is inspected by the flatness detection device for building engineering, the detection support platform is first moved to one side of the wall so that the detection support platform is parallel to the wall. At this time, the walking ball at one end of the detection slide bar abuts against the wall so that the position marked with the center value of the detection scale is aligned with the end of the detection sleeve. Then the detection support platform is moved vertically so that the detection slide bar abuts against the wall and moves. During the movement, it is observed whether the detection slide bar slides relative to the detection sleeve. If slippage occurs, the detection scale corresponding to the end face of the corresponding detection sleeve can be observed. If the value is large, it can be marked and recorded. After inspecting a part of the wall from bottom to top, the detection support platform is moved parallel to the wall, so that the other parts of the wall are inspected in turn, so that the area of ​​the wall that can be inspected at a time is larger, the inspection is more convenient, and the inspection efficiency is effectively improved;

[0029] 2. A warning bracket is arranged at the lower side of the detection sleeve. The warning bracket is rotatably connected to the warning support plate and abuts against one end of the detection slide bar through a torsion spring. When the detection slide bar slides, one end of the warning support plate continuously abuts against the detection slide bar, so that the warning support plate rotates. The rotating warning support plate will abut against the power generation board, so that the corresponding warning light is lit. At this time, the operator can directly observe which detection slide bar is slipping, thereby reducing the probability of missed detection and being more convenient.

[0030] 3. Two sets of marking numbers are provided on the side ends of the wheel body, and the two sets of marking numbers are connected end to end so that the two marking numbers symmetrical with the axis of the wheel body are the same number. By observing the control tube on the detection support platform, the marking number at the end of the wheel body away from the wall can be directly observed. The marking number is the same as the marking number at the end of the wheel body facing the wall, which makes it more convenient and accurate to adjust the marking number.

DETAILED DESCRIPTION

[0037] The following is combined with Figure 1-5 This application is described in further detail.

[0038] See also Figure 1 A construction engineering flatness detection device includes a detection support platform 1 supported on the ground close to a wall, a detection support frame 2 vertically slidably arranged on the top of the detection support platform 1, and a detection component 3 arranged on the top of the detection support frame 2.

[0039] A plurality of universal pulleys 4 are fixed to the lower end surface of the detection support platform 1 by bolts, and a guide track 5 is provided on the side of the detection support platform 1 close to the wall. The guide track 5 is arranged parallel to the wall, and a suction cup 6 is evenly fixed to the side end of the guide track 5 close to the wall by bolts. The guide track 5 can be horizontally and parallelly adsorbed to the wall through the suction cup 6, and a row of guide rollers 7 are rotatably connected to the side end of the detection support platform 1 close to the wall by a rotating shaft, and the rotation axis of the guide rollers 7 is perpendicular to the wall, and a guide groove 8 with two through ends is opened at the upper side end of the guide track 5 along its own length direction, and the guide roller 7 is embedded in the guide groove 8 and slides and rolls along the length direction of the guide groove 8, so that the detection support platform 1 moves parallel to the wall under the guidance of the guide track 5.

[0040] See also Figure 1 and Figure 2The top of the detection support platform 1 is provided with a mounting groove 9, and an adjustment platform 10 is embedded in the mounting groove 9. The detection support platform 1 is vertically provided with a connection hole 11 on the bottom wall of the mounting groove 9. The lower end surface of the adjustment platform 10 is integrally provided with a connection column 12 inserted into the connection hole 11. The upper end surface of the adjustment platform 10 is threadedly connected with an adjustment bolt 13 near the corner. The adjustment bolt 13 is vertical. One end of the adjustment bolt 13 passes through the adjustment platform 10 and abuts against the bottom wall of the mounting groove 9. The adjustment platform 10 can be adjusted to a completely horizontal state by rotating the adjustment bolt 13. Two level gauges 14 are embedded in the middle of the upper end surface of the adjustment platform 10. The two level gauges 14 are arranged perpendicular to each other. When adjusting the adjustment platform 10 through the adjustment bolt 13, it can be adjusted by observing the two level gauges 14.

[0041] The upper end surface of the adjustment platform 10 is vertically fixed with a lifting cylinder 15 by bolts at positions near both sides, and the two ends of the detection support frame 2 are fixed to the top of the piston rods of the two lifting cylinders 15 by bolts. The detection support frame 2 can be vertically moved by the lifting cylinder 15.

[0042] See also Figure 3 The detection assembly 3 includes a plurality of detection sleeves 16 arranged horizontally and pointing vertically to the end surface of the wall to be detected, and a detection slide rod 17 slidably inserted into each detection sleeve 16 . The middle part of the detection sleeve 16 is welded to the top of the detection support frame 2. The detection sleeve 16 is in the shape of a circular tube. A sliding hole 18 is formed in the middle part of the detection sleeve 16 for the detection slide bar 17 to be inserted and slide. The two ends of the detection slide bar 17 protrude from the two ends of the detection sleeve 16. The detection sleeve 16 is integrally formed with a pressure ring on the inner peripheral wall of the sliding hole 18. The detection sleeve 16 is embedded with a compression spring 19 in the sliding hole 18. The compression spring 19 abuts against the end of the pressure ring close to the wall. A pressure plate 20 abutting against the end of the compression spring 19 close to the wall is welded to the side end of the detection slide bar 17, so that the compression spring 19 can drive the detection slide bar 17 to move to one side of the wall. A walking ball 21 is rollingly embedded in the end of the detection slide bar 17 close to the wall. When the detection slide bar 17 abuts the walking ball 21 against the wall and moves, the walking ball 21 rolls.

[0043] The detection slide bar 17 is protruding from the two ends of the detection sleeve 16, and the lateral ends thereof are engraved with detection scales 22 along the length direction. The detection scales 22 extend from the end surface of the detection sleeve 16 to the two ends of the detection slide bar 17 and the values ​​gradually increase. When the detection slide bars 17 are both in contact with the wall and move vertically, once the wall appears concave or convex, the detection slide bar 17 will slide in the sliding hole 18, thereby causing the detection scale 22 corresponding to the end surface of the detection sleeve 16 to change. At this time, the detection scale 22 corresponding to the end surface of the detection sleeve 16 is the corresponding indication of the unevenness change of the wall.

[0044] See also Figure 3 and Figure 4The lower side end of the detection sleeve 16 is welded with a warning bracket 23 on the side away from the end face to be detected on the wall. The warning bracket 23 extends to the side away from the wall. The warning bracket 23 is rotatably connected to the warning support plate 24 through a torsion spring. The warning support plate 24 is pressed against the end of the detection slide bar 17 away from the walking ball 21 through the torsion spring. The warning bracket 23 is vertically welded with a triggering electric plate 25 for the warning support plate 24 to touch on both sides of the warning support plate 24 close to and away from the end face to be detected on the wall. The lower side end of the warning bracket 23 is fixed with a warning light 26 by bolts. When the detection slide bar 17 slides, the warning support plate 24 will rotate. When the warning support plate 24 contacts the power generation plate 25, the warning light 26 is lit. At this time, it can be known which detection slide bar 17 has slipped.

[0045] An observation detection tube 27 is provided on the side of the detection support frame 2 away from the end face of the wall to be detected. The observation detection tube 27 includes a second pipe 28 horizontally arranged on the upper side of the detection support platform 1 and a first pipe 29 vertically welded to the second pipe 28 at one end close to the wall. A first reflective lens 30 is obliquely arranged at the connection between the first pipe 29 and the second pipe 28. The middle part of the first pipe 29 is a telescopic bellows. The top of the first pipe 29 is fixed to the middle part of the warning bracket 23 by bolts and points to the detection scale 22 corresponding to the end of the detection sleeve 16 away from the wall, so that the change of the detection scale 22 can be observed at the end of the second pipe 28 away from the wall.

[0046] See also Figure 3 and Figure 5 A marking wheel 31 is provided at the lower end of each detection sleeve 16 on the side close to the end face of the wall to be detected. The marking wheel 31 includes a wheel frame 32 and a wheel body 33 rotatably connected to the wheel frame 32 through a rotating shaft. The rotating shaft of the wheel body 33 is parallel to the wall. A marking cylinder 34 is horizontally fixed to the lower end of the detection sleeve 16 on the side of the wheel frame 32 away from the wall by bolts. The piston rod of the marking cylinder 34 points vertically to the wall and is fixed to the wheel frame 32 by bolts, so that the marking cylinder 34 can drive the entire marking wheel 31 to move toward the side of the wall.

[0047] Two sets of marking numbers 35 are evenly engraved on the circumferential side ends of the wheel body 33, each set of marking numbers 35 includes five numbers from 1 to 5, and the two sets of marking numbers 35 are connected end to end so that the two marking numbers 35 symmetrical about the axis of the wheel body 33 are the same.

[0048] The rotating shaft of the wheel body 33 protrudes from one end of the wheel frame 32 and is connected to the passive gear 36 through a key. The lower side end of the detection sleeve 16 is connected to the driving gear 37 through the rotating shaft at one side of the passive gear 36. The driving gear 37 is located on the side of the passive gear 36 away from the wall and meshes with the passive gear 36. The lower side end of the detection sleeve 16 is fixed with a number adjustment cylinder 38 in parallel with one side of the marking cylinder 34 through bolts. The piston rod of the number adjustment cylinder 38 is fixed with a number adjustment rack 39 through bolts, and the number adjustment rack 39 is meshed with the driving gear 37. The number adjustment cylinder 38 can drive the number adjustment rack 39 to turn the driving gear 37 to rotate, and finally realize the rotation of the wheel body 33.

[0049] An observation and control tube 40 is arranged on the lower side of the marking cylinder 34, which is aligned with the end face of the wheel body 33 to be detected away from the wall. The observation and control tube 40 includes a third pipe 41 horizontally fixed to the lower side end of the marking cylinder 34 by bolts, a fourth pipe 42 vertically welded to the end of the third pipe 41 away from the wall, and a fifth pipe 43 horizontally welded to the upper end face of the detection support platform 1. The end of the fifth pipe 43 close to the wall is welded to the lower end of the fourth pipe 42, and the second pipe 28 is welded in parallel to the upper side end of the fifth pipe 43. The inner wall of the connection between the third pipe 41 and the fourth pipe 42 and the inner wall of the connection between the fourth pipe 42 and the fifth pipe 43 are both obliquely arranged with a second reflective lens 44, and the two second reflective lenses 44 are parallel to each other. The middle part of the fourth pipe 42 is a telescopic bellows.

[0050] The implementation principle of this embodiment is:

[0051] When the vertical end face of the wall is inspected by the construction engineering flatness detection device, the guide track 5 is first adsorbed on the wall parallel to the wall through the suction cup 6, and then the guide roller 7 on the detection support platform 1 is slid into the guide slide groove 8 of the guide track 5, so that the detection support frame 2 is parallel to the wall. At this time, the walking ball 21 at one end of the detection slide bar 17 abuts against the wall, so that the position marked with the center value of the detection scale 22 is aligned with the end of the detection sleeve 16, and then the detection support frame 2 is slowly moved vertically by the lifting cylinder 15, so that the detection slide bar 17 abuts against the wall for vertical movement, and the warning light 26 is observed during the detection process. When the detection slide bar 17 slides, one end of the warning support plate 24 continues to abut against the detection slide bar 17, so that the warning support plate 24 rotates, and the rotating warning support plate 24 will abut against the contact power generation plate 25, so that the corresponding warning light 26 is lit, and the lifting cylinder 15 is stopped at this time, and then the second pipeline 2 is observed. 8, the first reflecting lens 30 inside can reflect the detection scale 22 aligned with the first pipe 29, so that the operator can read the detection scale 22 of the alignment detection sleeve 16 through horizontal observation, and after reading the scale, observe the inside of the fifth pipe 43, and observe the marked number 35 on the wheel body 33 through the two second reflecting lenses 44. When the marked number 35 is inconsistent with the scale, the adjusting rack 39 is driven to move by the adjusting cylinder 38, and the driving gear 37 is driven to rotate by the adjusting rack 39. At this time, the driving gear 37 is engaged with the passive gear 36, so that when the active gear 37 rotates, the passive gear 36 can be driven to rotate, thereby realizing the rotation of the wheel body 33, so as to adjust the marked number 35 at one end of the wall. After the adjustment is accurate, the marking wheel 31 is driven by the marking cylinder 34 to mark the wall, and then the detection support platform 1 is moved parallel to the wall, so as to detect other parts of the wall in turn.

[0052] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
