Description

[0002] In the field of civil engineering, building construction and decoration, the verticality of vertical structures such as walls, columns and piers is one of the key indicators of construction quality. Deviation in verticality can affect structural safety, flatness of subsequent decoration and overall aesthetics.

[0003] Currently, the commonly used verticality detection method in the field mainly relies on manual operation of traditional mechanical detection rulers. During detection, the operator needs to manually stick the detection ruler to the wall to be detected, and judges by visually observing the gap between the ruler and the wall or relying on the level bubble on the ruler. This method has obvious defects: when there are local protrusions or depressions on the wall, the rigid detection ruler cannot adapt to the fit, which will form a gap or cause warping, which not only wears the ruler surface and the wall, but also directly leads to misjudgment of the verticality and flatness, and cannot truly reflect the continuous undulating condition of the wall.

DETAILED DESCRIPTION

[0028] In order to make the skilled in the art better understand the technical solutions of the present application, the present application will be further described in detail below in combination with the drawings.

[0029] As shown in the accompanying Figure 1 to the accompanying Figure 6 :

[0030] Example one:

[0031] The civil engineering verticality detection device is characterized in that: the installation plate 1 is usually made of metal materials (such as aluminum alloy or steel structure) with excellent rigidity, so as to ensure that no self-deformation occurs during leveling and detection; the electric push rod 2 is installed on one side of the top of the installation plate 1; the electric push rod 2 is selected from a type with moderate stroke, uniform push speed and self-locking function; the driving end of the electric push rod 2 is vertically upward; the installation block 3 is fixedly connected to the top of the electric push rod 2 through a flange plate or direct welding; the installation block 3 is internally provided with a precise containing space for arranging the detection ruler 4; the detection assembly 5 for detecting the verticality of the wall surface is arranged in the detection ruler 4; the detection assembly 5 comprises the first sliding groove 51, the empty groove 52, the first sliding block 53, the roller 54, the first spring 55, the guide groove 56, the guide block 57 and the scale line 58.

[0032] Further, the first sliding groove 51 is provided with two groups and is arranged at the top and the bottom positions close to the side away from the installation plate 1 of the detection ruler 4; the empty groove 52 is arranged in the inner walls of the top and the bottom of the first sliding groove 51; the first sliding block 53 is slidingly connected to the first sliding groove 51; the roller 54 is installed on one side of the first sliding block 53; the first spring 55 is installed in the first sliding groove 51 and is fixedly connected to one side of the first sliding block 53 away from the roller 54 and one side of the inner wall of the first sliding groove 51 away from the roller 54; the guide groove 56 penetrates through the inner walls of the two sides of the first sliding groove 51; the guide block 57 is fixedly connected to the two sides of the first sliding block 53 and is slidingly connected to the guide groove 56; the scale line 58 is sprayed on the surfaces of the two sides of the detection ruler 4 and is above the guide groove 56; the roller 54 is preferably made of wear-resistant nylon or rubber coating material, and the outer ring is smooth, which can realize low-resistance rolling on the wall surface and effectively protect the wall surface coating from being scratched; the axis direction of the roller 54 is perpendicular to the length direction of the detection ruler 4, so as to ensure that the roller 54 rolls up and down along the wall surface.

[0033] Working principle: first, the operator pushes the whole device to the front of the wall to be detected, so that the long side of the installation plate 1 is approximately parallel to the wall to be detected, and a space of about 10-15 cm is reserved between the two, so that the detection ruler 4 can be inserted subsequently; at this time, the level bubble 7 on the top of the installation plate 1 is observed, and the bubble is usually not in the center; the lifting assembly 8 of the four corners is manually adjusted (the specific leveling details are described in embodiment three), so that the installation plate 1 reaches the approximately horizontal state, and a preliminary reference plane is established for subsequent accurate detection;

[0034] Detection ruler alignment and start: Turn on the control switch of the electric push rod 2 (which can be a line control or wireless remote control), slowly extend the drive rod of the electric push rod 2, and smoothly push the detection ruler 4 towards the wall surface through the mounting block 3. This process needs to be slow until the two upper and lower rollers 54 of the detection ruler 4 are in slight contact with the wall surface. At this time, the operator should judge by observation or sound (slight contact sound) to ensure that the rollers 54 have been contacted, and the metal or composite material ruler body of the detection ruler 4 has not been scraped with the wall surface. Keep the electric push rod 2 continuously pushing the detection ruler 4 vertically upwards along the wall surface at a constant low speed (for example, 2-5 cm per second), and the two sets of upper and lower rollers 54 roll on the wall surface during the entire climbing process;

[0035] When encountering a protrusion: When the rollers 54 roll to a local protrusion (such as mortar clumps, formwork joint) of the wall surface, the protrusion exerts a reverse force on the rollers 54, which overcomes part of the elastic force of the first spring 55, pushes the first sliding block 53 with the rollers 54 to retract along the first sliding groove 51 to the inside of the detection ruler 4, and the first spring 55 is further compressed to store energy. The guide block 57 synchronously slides inwards in the guide groove 56;

[0036] When encountering a depression: When the rollers 54 roll into a local depression (such as local insufficient plastering, small holes) of the wall surface, the wall surface pressure exerted on the rollers 54 decreases or even disappears. At this time, the compressed first spring 55 releases the stored energy and rebounds to push the first sliding block 53 and the rollers 54 to extend outwards along the first sliding groove 51 until the rollers 54 are tightly attached to the wall surface of the depression again, and the guide block 57 also slides outwards,

[0037] Through the continuous dynamic process of compression or rebound, the rollers 54 always move along the wall surface contour with basically constant pressure, regardless of the micro or macro undulations of the wall surface;

[0038] When the detection ruler 4 is driven by the electric push rod 2 to rise from the bottom starting position to the target height (for example, 3 meters high) that needs to be detected, the electric push rod 2 is turned off, at this time, the operator can read the numerical value of the scale line 58 corresponding to the two guide blocks 57 at the top and bottom of the detection ruler 4 respectively, assuming that the top guide block 57 indicates a reading of +2.5 mm (indicating that the roller is retracted by 2.5 mm), and the bottom guide block 57 indicates a reading of -1.0 mm (indicating that the roller is extended by 1.0 mm), and the vertical distance between the two sets of detection components on the detection ruler 4 is known as L (for example, 2.5 meters), then the verticality deviation angle θ of the wall in this height can be approximately calculated by the arctangent function: θ ≈ arctan((|2.5|+|-1.0|) / L)=arctan(3.5mm / 2500mm), the calculation result is the inclination angle of the wall relative to the theoretical vertical line, more simply, in construction, the difference between the two points (3.5 mm in this example) is usually directly used as the verticality deviation value of the wall, and whether it is qualified is judged according to the construction specification.

[0039] Embodiment two:

[0040] The difference between this embodiment and the previous embodiment is that the detection ruler 4 and the mounting block 3 are connected at the mounting assembly 6, and the mounting assembly 6 includes a mounting slot 61, a mounting hole 62, a through slot 63, a mounting rod 64, a second sliding slot 65, a second sliding block 66, a second spring 67 and a first pulling block 68.

[0041] Further, the mounting slot 61 is provided on the top of the mounting block 3 and is adapted to the size of the detection ruler 4, the mounting hole 62 is provided on both sides of the detection ruler 4 near the bottom, the through slot 63 penetrates the inner walls of both sides of the mounting slot 61, the mounting rod 64 is movably connected to the through slot 63 and is adapted to the size of the mounting hole 62, the second sliding slot 65 is provided on the inner wall of the through slot 63, the second sliding block 66 is fixedly connected to the outer periphery of the mounting rod 64 and is slidably connected to the second sliding slot 65, the second spring 67 is sleeved on the outer periphery of the mounting rod 64 and has two ends fixedly connected to the side of the second sliding block 66 away from the mounting slot 61 and the inner wall of the second sliding slot 65 away from the mounting slot 61, and the first pulling block 68 is fixedly connected to the outer end of the mounting rod 64.

[0042] Working principle: Before performing the verticality test, first pull the first pull block 68 outwards. This will cause the second slider 66 to slide outwards along the second groove 65 via the mounting rod 64, compressing the second spring 67. When the mounting rod 64 moves out of the mounting groove 61 and into the through groove 63, place the bottom of the measuring scale 4 into the mounting groove 61, ensuring that the mounting hole 62 and the mounting rod 64 are on the same axis. Then, release the first pull block 68. The second spring 67 will rebound and, through the second slider 66, will move the mounting rod 64 inwards. When the mounting rod 64 is inserted into the mounting hole 62, the bottom of the measuring scale 4 will be fixed in the mounting groove 61, thus completing the installation of the measuring scale 4. After the test is completed, pull the first pull block 68 outwards again to move the mounting rod 64 outwards. When the mounting rod 64 moves out of the mounting hole 62, the bottom of the measuring scale 4 will be removed from the mounting groove 61, thus completing the disassembly of the measuring scale 4. This design allows the measuring ruler 4 to be installed and removed quickly, thus ensuring work efficiency.

[0043] Example 3:

[0044] This embodiment is basically the same as the previous embodiment, except that a level bubble 7 for detecting the levelness of the mounting plate 1 is installed on the top of the mounting plate 1 on one side of the electric push rod 2, and lifting components 8 for adjusting the height of the four corners of the mounting plate 1 are provided on the outer sides of the four corners of the mounting plate 1. The lifting components 8 include a connecting plate 81, a mounting base 82, a lifting groove 83, a lifting block 84, a screw 85, a rotating groove 86, a rotating shaft 87, a cavity 88, a third sliding groove 89, a connecting groove 810, a pull rod 811, a third slider 812, a third spring 813, a slot 814, a locking block 815, and a second pulling block 816.

[0045] Furthermore, the connecting plate 81 is fixedly connected to the bottom of the four corners of the mounting plate 1, the mounting base 82 is movably connected to the outer side of the four corners of the mounting plate 1, the lifting groove 83 is opened on the side surface of the mounting base 82 near the connecting plate 81, the lifting block 84 is fixedly connected to the connecting plate 81 and slidably connected to the lifting groove 83, the screw 85 passes through and is threadedly connected to the lifting block 84, the rotating groove 86 is opened on the inner walls of the top and bottom of the lifting groove 83, the rotating shaft 87 is fixedly connected to the top and bottom of the screw 85 and rotatably connected to the rotating groove 86, the cavity 88 is opened inside the top set of rotating shafts 87, the third sliding groove 89 is opened on the inner walls of both sides of the cavity 88, and the connecting groove 810 passes through the top of the top set of rotating grooves 86. The inner wall of the part is connected to the cavity 88. The pull rod 811 is movably connected to the connecting groove 810 and its bottom extends into the cavity 88. The third slider 812 is fixedly connected to the bottom of the pull rod 811 and slidably connected to the cavity 88 and the third slide groove 89. The third spring 813 is sleeved on the outer periphery of the pull rod 811 near the bottom and its two ends are fixedly connected to the top of the third slider 812 and the top inner wall of the cavity 88, respectively. The slot 814 is opened on the top surface of the mounting base 82 and is distributed in a ring on the top outer periphery of the connecting groove 810. The locking block 815 is fixedly connected to the outer periphery of the pull rod 811 near the top and is adapted to the size of the slot 814. The second pull block 816 is fixedly connected to the top of the pull rod 811.

[0046] Working principle: Place the entire device in the testing area, with the four mounting bases 82 in contact with the ground. At this time, the mounting plate 1 is likely to be tilted. Observe the horizontal bubble 7 located in the prominent position in the center of the mounting plate 1. The bubble in the horizontal bubble 7 will drift to the higher side. Note the direction and approximate distance of the bubble's displacement. Walk to the mounting base 82 of the corner that needs to be raised, pinch the second pull block 816 with your hand, and lift it vertically upwards. The pull rod 811 will rise accordingly, causing the third slider 812 to compress the third spring 813. At the same time, the locking block 815 fixed on the pull rod 811 will also be lifted out of its current slot 814 and disengaged. At this time, the pull rod 811 and the mounting base 82... The circumferential lock between them is released, maintaining the upward lifting state (the third spring 813 is compressed), and then the second pull block 816 is rotated clockwise or counterclockwise. Since the third slider 812 is stuck in the third slide groove 89, rotating the second pull block 816 will drive the third slider 812, the pull rod 811, and the top rotating shaft 87 fixed thereto to rotate together. The rotation of the rotating shaft 87 directly drives the screw 85 to rotate. The rotation of the screw 85 is converted into the linear motion of the lifting block 84 in the lifting groove 83 through its threaded engagement with the lifting block 84. If rotated clockwise (viewed from above), the lifting block 84 usually rises (depending on the direction of the thread), and the mounting plate 1 at this corner is lifted by the connecting plate 81.Conversely, it descends. The operator can observe the movement of the bubble in level bubble 7 while rotating. When the height of this angle is adjusted to move the bubble in level bubble 7 a certain distance towards the center, stop rotating. Then, slowly release the second pull block 816. Under the downward push of the third spring 813, the pull rod 811 drives the locking block 815 to descend. Since the locking block 815 may not be aligned with a certain slot 814 at this time, the second pull block 816 can be rotated very slightly in both directions (at a very small angle) until you feel the locking block 815 "click" into a slot 814. At this time, the circumferential position of the pull rod 811 and the rotating shaft 87 is completely locked, and the screw 85 can no longer rotate freely. The height of this angle is then firmly locked at the current position. After completing the coarse adjustment of one angle, rotate to the opposite angle or another angle that is too high / too low as indicated by the bubble, and repeat the above process. After each adjustment, the bubble in level bubble 7 will be closer together. When the center is nearly level, a very small angle of rotation is required. Multiple ring-shaped slots 814 provide fine adjustment levels, allowing for gradual fine-tuning. Through independent and coordinated adjustments to the height of the four corners, the bubble in the leveling bubble 7 is perfectly positioned within the central circle. At this point, the mounting plate 1 is truly level. After leveling, the entire mounting plate 1 forms a precise horizontal reference plane. Since the electric push rod 2 is vertically installed on this plane, its trajectory is necessarily perpendicular to the horizontal plane, i.e., the absolute vertical direction. Therefore, the movement trajectory of the measuring ruler 4 fixed to the top of the electric push rod 2 is also strictly limited within the vertical plane. This fundamentally eliminates the systematic error introduced by the tilt of the measuring reference due to uneven ground, ensuring that the wall verticality measurement value described in Example 1 truly reflects the deviation of the wall relative to the direction of gravity, resulting in highly reliable results.

[0047] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
