Traditionally, tools such as a level and a plumb line are used to perform visual measurement along the outer surface of the wall. However, this method has poor measurement accuracy. In order to ensure accuracy, measuring equipment with a laser sensor is currently used to perform displacement measurement along the outer surface of the wall. When the existing measuring equipment is in use, the measuring equipment is generally moved along the outer surface of the wall to perform displacement measurement.

[0043] The two first threaded rods 28 extending into the two first straight cylinders 23 are respectively arranged on the outward ends of the two T-shaped push plates 25, and the T-shaped push plates 25 are moved by the first threaded rods 28. The two first straight cylinders 23 extending to the inner wall of the U-shaped correction frame 2 and respectively threadedly connected to the outward ends of the two first threaded rods 28 are respectively rotatably connected to the outward ends of the two vertical parts of the U-shaped correction frame 2, and the first threaded rods 28 are moved forward and backward by the first straight cylinder 23. Then, the two first guide rods 24 located at the lower side of the first straight cylinder 23 and penetrating the vertical part of the U-shaped correction frame 2 and slidably connected to the U-shaped correction frame 2 are respectively installed on the outward ends of the two T-shaped push plates 25, and the movement of the T-shaped push plates 25 is guided by the first guide rods 24.

[0044] The upper ends of the vertical parts of the two T-shaped slides 34 located on the front and rear sides of the flexible rod 8 are slidably connected to the lower end of the horizontal part of the U-shaped measuring frame 3. Through the T-shaped slide 34, a mounting carrier is provided for the second threaded rod 39 and other components. The inner end surfaces in the middle of the two T-shaped slides 34 are both recessed outward to form a triangular mounting groove 38 extending to the lower end of the T-shaped slide 34 and having a narrow upper and wide lower cross section. Through the mounting groove 38, an installation space is provided for the laser measuring device, and two laser measuring devices are respectively arranged in the two mounting grooves 38. The laser measuring device is used to detect the parallelism of the wall during the construction of the house. The laser measuring device can use a second laser sensor 37;

[0045] The two second threaded rods 39 extending into the two second straight cylinders 31 are respectively arranged on the outward ends of the two T-shaped slides 34, and the T-shaped slide 34 is moved by the second threaded rods 39, and the two second straight cylinders 31 extending to the inner wall of the U-shaped measuring frame 3, which are respectively threadedly connected to the outward ends of the two second threaded rods 39, are respectively rotatably connected to the outward ends of the two vertical parts of the U-shaped measuring frame 3, and the second threaded rods 39 are moved by the second straight cylinders 31, and then the two second guide rods 32 located on the lower side of the second straight cylinder 31 and penetrating the vertical part of the U-shaped measuring frame 3 and slidingly connected to the U-shaped measuring frame 3 are symmetrically installed on the outward ends of the two T-shaped slides 34, and the movement of the T-shaped slide 34 is guided by the second guide rods 32.

[0046] When in use, first clamp the two U-shaped clamps 1 onto the top of the wall, and then rotate the two screws 12. Since the screws 12 are threadedly connected to the U-shaped clamps 1, the screws 12 rotate and move backward at the same time, thereby causing the extrusion plate 13 to move backward and make extrusion contact with the outer end surface of the wall, thereby fastening the two U-shaped clamps 1 to the wall.

[0047] Then, the two first straight cylinders 23 are rotated. Since the first straight cylinder 23 is threadedly connected to the first threaded rod 28, the first straight cylinder 23 rotates and simultaneously causes the first threaded rod 28 to move inward, thereby causing the two T-shaped push plates 25 to move inward and contact the front outer end surface of the wall. Then, the two second straight cylinders 31 are rotated. Since the second straight cylinder 31 is threadedly connected to the second threaded rod 39, the second straight cylinder 31 rotates and simultaneously causes the second threaded rod 39 to move inward, thereby causing the two T-shaped slide plates 34 to move inward and contact the front outer end surface of the wall, thereby adjusting the distance between the two T-shaped push plates 25 and the distance between the two T-shaped slide plates 34, effectively meeting the detection of walls of different widths and improving the scope of use.

[0048] Then, the motor 91 on the left side is started, thereby driving the winding wheel 92 on the left side to rotate, thereby contracting the pull rope 7 on the left side, thereby driving the second column 6 to move leftward, thereby causing the U-shaped correction frame 2 to move leftward, thereby causing the two T-shaped push plates 25 to move leftward along the front and rear surfaces of the wall respectively, and also causing the two guide plates 22 to move leftward, and causing the rubber sleeve 5 to move leftward, thereby causing the U-shaped measuring frame 3 to move leftward;

[0049] Then, the two T-shaped slides 34 are respectively moved to the left along the front and rear surfaces of the wall, so that the two second laser sensors 37 are moved to the left along the front and rear surfaces of the wall, so that the two second laser sensors 37 are used to perform synchronous displacement measurement of the front and rear surfaces of the wall, so that two sets of data are used for comparative analysis, effectively reducing the probability of data errors due to factors such as depressions, and effectively ensuring the accuracy of displacement measurement;

[0050] When a brick in the top part of the wall is bulged, the two T-shaped push plates 25 are guided by the two guide plates 22 to move to the left, and the two T-shaped push plates 25 are respectively moved to the front and rear ends of the bulged brick. At this time, the two moving T-shaped push plates 25 push the bulged brick to correct the top of the wall, effectively reducing the probability of changes in the initial position of the measurement due to the bulge at the top part of the wall, and effectively ensuring the accuracy of the displacement measurement.

[0051] When the outer surface of the wall is in a curved state, the U-shaped clamping plate 1 on the left is fastened to the wall, and the rear vertical portion of the U-shaped clamping plate 1 on the right and the extrusion plate 13 are respectively fitted to the front and rear end surfaces of the wall, and the two T-shaped push plates 25 and the two T-shaped slide plates 34 are moved inwards and contact the front outer end surface of the wall through the two first straight cylinders 23, the two first threaded rods 28, the two second straight cylinders 31 and the two second threaded rods 39;

[0052] Then, through the motor 91 on the left, the winding wheel 92 on the left, the pull rope 7 on the left, the second column 6, the U-shaped correction frame 2, the rubber sleeve 5 and the U-shaped measuring frame 3, the two T-shaped push plates 25 and the two T-shaped slide plates 34 are respectively moved to the left along the front and rear surfaces of the wall, and under the guidance of the two guide plates 22, the two T-shaped push plates 25 enter the curved part of the wall, thereby causing the flexible rod 8 to bend and deform, and with the assistance of the rubber sleeve 5, the U-shaped measuring frame 3 moves along the bent and deformed flexible rod 8, so that the two T-shaped slide plates 34 are guided to move on the curved part of the wall, thereby realizing displacement measurement of the curved wall, improving the scope of use, and effectively reducing the process and time, and effectively ensuring the accuracy of displacement measurement;

[0053] When the measurement is completed, the two U-shaped clamps 1 are first disassembled, and then the motor 91 located on the right, the winding wheel 92 located on the right, the pull rope 7 located on the right and the first column 4 are used to return the U-shaped correction frame 2, the rubber sleeve 5, the U-shaped measuring frame 3, the two T-shaped push plates 25 and the two T-shaped slide plates 34 to their original positions to the right, thereby ensuring the subsequent normal measurement operation.

[0054] Embodiment 2: Two T-shaped push plates 25 are used to correct the top of the wall, and two second laser sensors 37 are used to synchronously measure the displacement of the front and rear end surfaces of the wall to ensure the accuracy of the displacement measurement. However, some house walls have protruding buildings such as bay windows, which cause the protruding buildings to block the second laser sensor 37, making it impossible for the second laser sensor 37 to effectively measure the displacement of the outer surface of the wall located on the lower side of the protruding building, which will affect the scope of use. In order to ensure the construction quality of the house wall, tools such as level meters are generally used to manually measure the outer surface of the wall on the lower side of the protruding building, which will increase the measurement process and time, and the displacement measurement accuracy is poor.

[0055] In order to solve the above problems, Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 and Fig.10 As shown, two laser measuring devices extending to the lower end of the T-shaped push plate 25 are respectively embedded on the inner ends of the transverse parts of the two T-shaped push plates 25. The laser measuring devices are used to detect whether there are protrusions on the wall during the construction of the house. The laser measuring device can use a first laser sensor 27, and the fixed parts of the two telescopic devices located between the second guide rod 32 and the second threaded rod 39 are respectively installed on the outer ends of the two T-shaped slide plates 34. The rack 35 is driven to move left and right through the telescopic device. The telescopic device can use an electric push rod 33;

[0056] The two racks 35 respectively installed at the left ends of the movable parts of the two telescopic devices are slidably connected to the outward ends of the two T-shaped slides 34, and the gear 36 is rotated through the racks 35. The two gears 36 located on the lower side of the second threaded rod 39 are respectively engaged with the upper ends of the two racks 35. The rotating shaft 361 is rotated through the gear 36. Then, the two rotating shafts 361 that pass through the T-shaped slides 34 and are connected to the laser measurer are respectively set on the inward ends of the two gears 36, and the gear 36 is connected to the laser measurer through the rotating shaft 361.

[0057] When in use, firstly, the two U-shaped clamps 1 are fastened and installed on the wall, and then the two first straight cylinders 23 and the two first threaded rods 28 are used to make the two T-shaped push plates 25 move inward and contact with the front outer end surface of the wall, and then the two second straight cylinders 31 and the two second threaded rods 39 are used to make the two T-shaped slide plates 34 move inward and contact with the front outer end surface of the wall, and then the motor 91 located on the left, the winding wheel 92 located on the left, and the pull rope 7 located on the left are used to make the second column 6, the U-shaped correction frame 2, the two T-shaped push plates 25, the rubber sleeve 5, the U-shaped measuring frame 3 and the two T-shaped slide plates 34 move to the left, and the two first laser sensors 27 and the two second laser sensors 37 move to the left, at this time, the first laser sensor 27 is used to detect the protruding buildings on the front and rear end surfaces of the wall, and the second laser sensor 37 is used to measure the displacement;

[0058] When the first laser sensor 27 detects a protruding building on the wall surface, the electric push rod 33 on the corresponding side is started, thereby driving the rack 35 to move to the left, and then the gear 36 and the rotating shaft 361 are rotated, so that the second laser sensor 37 swings to the left in the installation groove 38, and then the detection range of the second laser sensor 37 moves from one side of the protruding building to the bottom. When the first laser sensor 27 is separated from the protruding building, the electric push rod 33, the rack 35, the gear 36 and the rotating shaft 361 are used to swing the second laser sensor 37 to the right in the installation groove 38, and then the detection range of the second laser sensor 37 moves from the other side of the protruding building to the bottom, thereby realizing the displacement measurement of the wall surface below the protruding building, improving the scope of use, and effectively reducing the process and time, and effectively ensuring the accuracy of displacement measurement.

[0059] Embodiment three: A flexible rod 8 is used to connect the two U-shaped clamps 1, but the flexible rod 8 itself is prone to deformation due to its flexibility, which causes misalignment of the two U-shaped clamps 1 during installation. As a result, the two U-shaped clamps 1 cannot be placed at one time, and additional operations such as alignment are required, which increases the measurement time.

[0060] In order to solve the above problems, Fig.12 and Fig.13 As shown, two vertical portions of an L-shaped frame 101 arranged opposite to each other are located on the outside of the U-shaped mounting plate 9 and the horizontal portion is located on the upper side of the U-shaped mounting plate 9, and the vertical portions of the two U-shaped clamping plates 1 are respectively installed on the upper ends of the horizontal portions. Through the L-shaped frame 101, a structure formed by a plurality of first plates 102 and a plurality of second plates 104 is connected to the U-shaped mounting plate 9, and a plurality of second plates 104 are equidistantly arranged between the two L-shaped frames 101, and a mounting carrier is provided for the second handle 105 through the second plate 104;

[0061] The first plate 102 is movably installed between two adjacent second plates 104, and the first plate 102 is movably set between the second plate 104 located on the leftmost side and the L-shaped frame 101 located on the left side, and between the second plate 104 located on the rightmost side and the L-shaped frame 101 located on the right side. The first plate 102 is used in conjunction with the second plate 104 so that the assembly formed by the two U-shaped splints 1, the U-shaped correction frame 2 and the U-shaped measuring frame 3 can be folded, and the vertical portions of multiple first handles 103 with T-shaped cross sections are respectively installed at the middle position of the upper end of the first plate 102, and the first plate 102 is folded by the first handles 103, and the vertical portions of multiple second handles 105 with T-shaped cross sections are respectively installed at the middle position of the upper end of the second plate 104, and the second plate 104 is folded by the second handles 105.

[0062] When measuring displacement, the structure formed by the plurality of first plates 102 and the plurality of second plates 104 is first unfolded, and the two U-shaped clamps 1 are mechanically connected, and the two U-shaped clamps 1 are rigidly placed, and then the two U-shaped clamps 1 are clamped onto the wall, and then the displacement measurement operation is performed, so that the assembly formed by the two U-shaped clamps 1, the U-shaped correction frame 2 and the U-shaped measurement frame 3 and other components is installed at one time, which effectively reduces the probability of the two U-shaped clamps 1 being misaligned when placed due to the easy deformation of the flexible rod 8, and effectively reduces the measurement time;

[0063] Moreover, the structure is in an active state and will not prevent the flexible rod 8 from deforming, so the displacement measurement of the curved wall can be effectively performed. After the displacement measurement is completed, the two U-shaped clamps 1 are first disassembled, and then the structure is folded, so that the assembly formed by the two U-shaped clamps 1, the U-shaped correction frame 2 and the U-shaped measuring frame 3 is folded, and then the folded assembly is carried, so as to realize convenient transportation and facilitate use.

[0064] Although this specification is described according to implementation modes, not every implementation mode includes only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
