[0002] In building construction, the verticality of a building is one of the important considerations, and corresponding verticality detection devices are usually used to detect the verticality of the building.

When measurement is not required, the mounting rod can be placed in the placement slot, which makes the device easy to carry; and an extension rod is also provided to cooperate with the measuring rod to detect the flatness of the wall."

[0004] Existing verticality detection devices usually require that a cone line with a suspended cone block be brought close to the building surface to be measured, and then a tape measure is used to measure in sequence whether the distance between each point on the side of the building and the vertical cone line is consistent to judge the verticality of the building wall. However, the existing method has the disadvantages of manually measuring multiple times with a tape measure, which is cumbersome, and the viewing angle of each measurement reading is different, which is prone to reading errors and easily affects the accuracy of the measurement. To solve the above problems, we propose a verticality detection device for building construction. Summary of the Invention

[0030] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0031] See also Figure 1-9 An embodiment of the present invention provides a verticality detection device for building construction, including an automatic detection system, a locking mechanism 3, a cone 1, and a cone line 2. The cone 1 is suspended on the locking mechanism 3 through the cone line 2. The automatic detection system includes a monitoring device 4. The locking mechanism 3 is perpendicular to the building surface to be measured. The monitoring device 4 is used to emit detection light to the building surface to be measured and is received by a receiving device on the cone 1. The automatic detection system determines the verticality of the building surface to be measured based on the emission angle and reception angle of the detection light.

[0032] Specifically, the cone 1 is a solid metal cone, the cone line 2 is connected to the center of the flat end of the cone 1, the locking mechanism 3 includes a horizontal column, one end of the horizontal column is vertically fixed with a flat plate that fits the wall to be measured, and the horizontal column is equipped with a support frame 28 that can be supported on the ground. The support frame 28 is preferably a four-legged support frame, so that the horizontal column is perpendicular to the wall to be measured at a certain height from the ground. The monitoring device 4 can be selected as a servo motor 1 fixed to the horizontal column, and one end of the cone line 2 is connected to the output shaft of the servo motor 1. The output shaft of the servo motor can reel the cone line 2 when it rotates. The monitoring device 4 also includes a laser ruler, which is fixed to the output shaft of the servo motor 2. The servo motor 2 is fixed to the horizontal column. The laser ruler can be angularly deflected under the action of the servo motor, that is, the angle between the laser of the laser ruler and the horizontal column can be changed. Specifically, the laser of the laser ruler can always be directed to the side of the building to be measured. The monitoring device 4 also includes a laser receiving target installed on the cone 1;

[0033] In actual use, as shown in the accompanying drawings of the specification Figure 9 As shown, the cone line 2 with the cone 1 bolted thereto is suspended on one side of the wall to be measured by a clamping mechanism, and then the cone line 2 is slowly released by a pair of servo motors. The laser receiving target moves synchronously with the cone 1. At the same time, the light refracted by the laser ruler's laser irradiation on the wall to be measured can be received by the laser receiving target. Therefore, during the measurement process, servo motor 2 will adjust the angle between the laser ruler and the horizontal column as the position of the laser receiving target changes, thereby changing the position of the laser irradiation on the wall to be measured, so that the laser receiving target can always receive the light refracted by the laser ruler on the building wall, thereby indicating that the measured wall swept by the laser ruler during the deflection process is in a vertical state. If, during the entire process, the laser receiving target cannot receive the light refracted by the laser ruler on the wall to be measured, it indicates that the wall to be measured is not perpendicular to the ground. The entire process is simple to operate and does not require manual multi-point measurement with a tape measure. It is simple to operate and transforms the measurement from the existing multi-point measurement to linear measurement, further improving the measurement accuracy.

[0034] It is well known to those skilled in the art that the walls of buildings cannot be mirrors and there is a certain amount of diffuse reflection, so only a part of the light can be received. However, those skilled in the art can still accurately determine the specific location of light reflection by analyzing the concentration of light. This is common knowledge in the field of optics and will not be elaborated on.

[0035] Another embodiment provided by the present invention, specifically, the cone 1 is a solid metal cone, the cone line 2 is connected to the center of the flat end of the cone 1, the locking mechanism 3 can be selected as an F fixing clamp, the F fixing clamp is an F-type threaded clamp, which can be clamped and fixed to the fastening frame on the outside of the building, the cone line 2 is bolted and fixed to the clamp handle of the F fixing clamp, the length direction line of the clamp handle of the F fixing clamp is perpendicular to the wall surface of the building to be measured, and the monitoring device 4 can be selected as a laser ruler fixed at an acute angle to the clamp handle of the F fixing clamp. When the laser of the laser ruler can illuminate a specific point on the cone 1, it indicates that the cone line 2 is parallel to the building surface to be measured.

[0036] In actual use, first make the length direction line of the clamp handle of the F fixing clamp perpendicular to the wall surface of the building to be measured, then clamp and fix it with the fastening frame on the outside of the building, and then make the cone line 2 suspend the cone 1. Under normal circumstances, when the length direction line of the clamp handle of the F fixing clamp is parallel to the horizontal line, the straightening direction of the cone line 2 is perpendicular to the length direction line of the clamp handle of the F fixing clamp, and the laser energy of the laser ruler can be irradiated on a specific point on the cone 1. Since the length direction line of the clamp handle of the F fixing clamp is perpendicular to the wall surface of the building to be measured, if the wall surface is in a tilted state, the length of the clamp handle of the F fixing clamp will be perpendicular to the wall surface of the building to be measured. The vertical direction line is inevitably no longer parallel to the horizontal line of the ground, so the straightening direction of cone line 2 is no longer perpendicular to the length direction line of the clamp handle of the F fixing clamp. The installation angle of the laser ruler on the clamp handle of the F fixing clamp is fixed, so the laser of the laser ruler cannot illuminate a specific point on the cone 1. At this time, the reading displayed on the laser ruler is also an abnormal reading, indicating that the building wall is tilted. Therefore, even with the locking hardware on the building surface, it is still possible to detect the verticality of the building wall. At the same time, the contact area required for detection with the measured building is reduced, making it convenient to detect the verticality of the building.

[0037] In another embodiment provided by the present invention, the locking mechanism 3 includes a rod column 3.1, one end of the rod column 3.1 is equipped with a vertical assembly 3.2, and the end of the rod column 3.1 close to the vertical assembly 3.2 is provided with a limit assembly 3.3. The vertical assembly 3.2 and the limit assembly 3.3 cooperate to fix the rod column 3.1 perpendicular to the side of the measured building. During actual use, the rod column 3.1 is first perpendicular to the measured building surface with the assistance of the vertical assembly 3.2, that is, the axis of the column 3.1 is perpendicular to the measured building surface, and the rod column 3.1 is clamped and fixed to the fastening frame on the outside of the building through the limit assembly 3.3, thereby preventing the rod column 3.1 from loosening and keeping the rod column 3.1 in a perpendicular state to the side of the measured building.

[0038] In another embodiment provided by the present invention, the vertical assembly 3.2 includes a threaded opening 3.21 opened at the end of the rod column body 3.1, the center line of the threaded opening 3.21 coincides with the axial center line of the rod column body 3.1, and a threaded column 3.22 is spirally inserted into the interior of the threaded opening 3.21. A flat plate 3.23 is vertically fixed to the end of the threaded column 3.22 away from the rod column body 3.1, and the plate surface of the flat plate 3.23 can fit the surface of the building to be measured.

[0039] In another embodiment provided by the present invention, the plate body of the flat plate 3.23 is a box-type plate, the plate surface of the flat plate 3.23 is circular, that is, the flat plate 3.23 is a hollow structure, the hollow structure in the flat plate 3.23 is in the shape of a pancake, the flat plate 3.23 is rotatably installed with a rotating column 9 on one side close to the threaded column 3.22, one end of the rotating column 9 is rotatably connected to the inner wall surface of the cavity of the flat plate 3.23, and the other end of the rotating column 9 is fixed to the end of the threaded column 3.22, the axis of the rotating column 9 is perpendicular to the flat plate 3.23, the axis of the rotating column 9 coincides with the axis center of the threaded column 3.22, and the hollow structure in the flat plate 3.23 is provided with a fixed rotating column 9. The rotating disk 10 has a surface parallel to the surface of the flat plate 3.23. The rotating disk 10 can rotate in the hollow structure in the flat plate 3.23. The center of the rotating disk 10 is on the axis center of the rotating column 9. A plurality of hinge seats 11 are fixed on the edge line of the rotating disk 10. Each hinge seat 11 is movably hinged with a swing bar 12. When the swing bar 12 swings, the swing surface generated is perpendicular to the surface of the rotating disk 10. The swing bar 12 and the hinge seat 11 are connected by a tension spring 13. When the tension spring 13 is in a natural state, the length direction of the swing bar 12 is in the same plane as the surface of the rotating disk 10. At this time, the swing bar 12 is in an upright state.

[0040] A plurality of plugs 14 perpendicular to the surface of the flat plate 3.23 are movably connected to one side of the flat plate 3.23 near the threaded column 3.22. One end of the plug 14, which can be inserted into the hollow structure within the flat plate 3.23, is fixed to the inner wall of the flat plate 3.23 by a coil spring 15. The plurality of plugs 14 are arranged in a ring on the surface of the flat plate 3.23, and an annular groove 16 is formed at the same position on the circumference of each plug 14.

[0041] The plug post 14 has two states, namely an extended state and a retracted state. In the extended state, the coil spring 15 is in a naturally extended state, and one end of the plug post also extends outward from the flat plate 3.23. At the same time, the column body of the plug post 14 is also located on the trajectory line of the swing bar 12 in the upright state moving along the rotating disk 10, thereby limiting the rotation of the rotating disk 10, and the threaded column 3.22 cannot rotate relative to the flat plate 3.23. In the retracted state, the coil spring 15 is squeezed by the end of the plug post 14 and is in a collapsed deformation state. One end of the plug post 14 is flush with the surface of the flat plate 3.23. At this time, the groove body of the annular groove 16 is located on the trajectory line of the swing bar 12 in the upright state moving along the rotating disk 10, so that the swing bar 12 in the upright state can pass through the annular groove 16, so that the plug post 14 in the retracted state no longer limits the rotation of the rotating disk 10, and the threaded column 3.22 can also rotate relative to the flat plate 3.23.

[0042] In actual use, when the flat plate 3.23 is fitted with the building surface, when there is a gap between the flat plate 3.23 and the building surface, some of the plug posts 14 are still in the extended state, then the threaded posts 3.22 cannot be rotated relative to the flat plate 3.23. Only when all the plug posts 14 are in the retracted state, it means that the flat plate 3.23 is completely flush with the building wall, and the flat plate 3.23 and the building surface are on the same plane. At this time, the threaded posts 3 .22 can rotate relative to the flat plate 3.23. Under the spiral action of the threaded column 3.22 and the threaded opening 3.21, the threaded column 3.22 is further extended from the threaded opening 3.21, and the rod column body 3.1 is subjected to an axial force. Since the rod column body 3.1 is clamped and fixed to the fastening frame outside the building through the limiting assembly 3.3, the position of the rod column body 3.1 remains unchanged. The extension force of the threaded column 3.22 makes the flat plate 3.23 and the building wall fit more tightly.

[0043] In another embodiment provided by the present invention, the limit assembly 3.3 includes a slot 3.31 opened on the side of the rod column 3.1, and the slot 3.31 can be engaged with the fastening frame rod on the outer wall of the building. The bottom of the slot 3.31 can be optionally an arc slot, and a non-slip rubber pad is fixed to the bottom of the slot 3.31. The side wall of the slot 3.31 is perpendicular to the length direction line of the rod column 3.1. During actual use, the slot 3.31 is engaged with the fastening frame rod on the outer wall of the building. When the rod column 3.1 is subjected to axial force, the extrusion pressure between the side wall of the slot 3.31 and the fastening frame rod on the outer wall of the building increases, so that the slot 3.31 and the fastening frame rod on the outer wall of the building are more tightly engaged.

[0044] In another embodiment provided by the present invention, a sealing unit 3.32 is provided in the slot 3.31. When the sealing unit 3.32 is in its extended position, it can prevent the fastening rod on the exterior wall of the building from loosening from the slot 3.31. Specifically, the sealing unit 3.32 has an extended position and an avoidance position. When the sealing unit 3.32 is in its avoidance position, the slot of the slot 3.31 is in an open state, and the fastening rod on the exterior wall of the building can be freely engaged with or separated from the slot 3.31.

[0045] In another embodiment provided by the present invention, a connecting assembly 5 is installed on the rod column 3.1, so that one end of the cone line 2 can be fixedly connected to the rod column 3.1. The connecting assembly 5 includes a placement opening 5.1 opened on the side of the rod column 3.1. The opening direction of the placement opening 5.1 is consistent with the opening direction of the slot opening 3.31. A shaft roller 5.2 is rotatably installed in the placement opening 5.1. The axial direction of the shaft roller 5.2 is perpendicular to the axial center line direction of the rod column 3.1. The shaft roller 5.2 is equipped with a device that can wrap the cone line 2. During actual use, when the winding reel 6 rotates forward, the cone line 2 on the winding reel 6 is released until the cone line 2 reaches the maximum release length. At this time, the cone 1 also falls to the predetermined position, that is, the vertical distance between the cone 1 and the rod column 3.1 reaches the preset distance. When the winding reel 6 rotates reversely, the cone line 2 on the winding reel 6 is entangled and wound around the winding reel 6 until the cone 1 reaches the stop position on the rod column 3.1. At this time, the winding reel 6 stops rotating reversely.

[0046] In another embodiment provided by the present invention, a driving component 7 capable of driving the winding disk 6 to wind up the conical line 2 is provided on the rod column 3.1. The driving component 7 can be optionally a crank rod 18 located on one side of the rod column 3.1. The power output end of the crank rod 18 is fixed to the end of the shaft roller 5.2 extending from the placement port 5.1. Therefore, in actual use, the user can shake the crank rod 18 clockwise, and the anti-slip sleeve 27 is movably connected to the crank rod 18, so that the winding disk 6 and the shaft roller 5.2 both rotate forward. The user can shake the crank rod 18 counterclockwise to make the winding disk 6 and the shaft roller 5.2 both rotate in the opposite direction, thereby controlling the winding and releasing state of the conical line 2 by the winding disk 6.

[0047] In another embodiment provided by the present invention, a transmission assembly 8 is provided on the rod column 3.1, and the transmission assembly 8 can enable the sealing unit 3.32 to receive the driving force of the rod column 3.1. The transmission assembly 8 includes a construction cavity 19 located in the rod column 3.1. The construction cavity 19 is an L-shaped structure as a whole. The construction cavity 19 is composed of a first cavity 19.1 and a second cavity 19.2. The first cavity 19.1 is a long cavity, and the second cavity 19.2 is a plate-shaped cavity. The length direction of the first cavity 19.1 is parallel to the axis of the rod column 3.1. The second cavity 19.2 is located between the threaded port 3.21 and the slot port 3.31. The end of the first cavity 19.1 is vertically connected to the second cavity 19.2. The placement port 5.1 overlaps with the first cavity 19.1. The placement port 5.1 overlaps with the first cavity 19.1. .1 has a first cavity 19.1 on both side walls, that is, the placement opening 5.1 divides the first cavity 19.1 into two parts, wherein the first cavity 19.1 located between the second cavity 19.2 and the placement opening 5.1 is the long cavity portion of the first cavity 19.1, and the portion of the first cavity 19.1 that is only connected to the placement opening 5.1 is the short cavity portion of the first cavity 19.1. An axially movable rack rod 20 is movably adapted in the first cavity 19.1, one end of the rack rod 20 can extend into the second cavity 19.2, one end of the rack rod 20 is located in the short cavity portion of the first cavity 19.1, and the rack rod 20 is engaged with a torque gear 21 fixed to the shaft roller 5.2. A vertical rod 17 is provided in the second cavity 19.2 and is fixed perpendicularly to the end of the rack rod 20.

[0048] The sealing unit 3.32 includes a through hole 3.321 formed in the inner wall of the slot 3.31 and communicating with the second cavity 19.2. A pin hole 3.322 is formed on a side of the slot 3.31 away from the through hole 3.321. A pin rod 3.323 is movably inserted into the through hole 3.321. One end of the pin rod 3.323 is fixed to the vertical rod 17, and the other end of the pin rod 3.323 is capable of inserting into the pin hole 3.322. When the pin rod 3.323 is inserted into the pin hole 3.322, the sealing unit 3.32 is in an extended position. When the pin rod 3.323 is fully retracted into the second cavity 19.2, the sealing unit 3.32 is in a retracted position.

[0049] During actual use, when the shaft roller 5.2 rotates forward, the rack rod 20 moves toward the short cavity part of the first cavity 19.1 under the meshing drive of the torque gear 21. When the end of the rack rod 20 contacts the end of the short cavity part of the first cavity 19.1, the pin rod 3.323 is plugged into the pin hole 3.322. At this time, if the shaft roller 5.2 continues to rotate forward, the torque gear 21 slips forward. In other words, the shaft roller 5.2 can continue to rotate forward, but the forward rotation of the shaft roller 5.2 cannot cause the rack rod 20 to continue to move further toward the short cavity part of the first cavity 19.1. Similarly, When the shaft roller 5.2 rotates in the opposite direction, the rack rod 20 moves toward the cavity wall of the second cavity 19.2 perpendicular to the length direction of the rack rod 20 under the meshing drive of the torque gear 21. When the end of the rack rod 20 contacts the cavity wall of the second cavity 19.2, the pin 3.323 is completely retracted into the second cavity 19.2. At this time, if the shaft roller 5.2 continues to rotate in the opposite direction, the torque gear 21 slips in the opposite direction. In other words, the shaft roller 5.2 can continue to rotate in the opposite direction, but the reverse rotation of the shaft roller 5.2 cannot cause the rack rod 20 to move further toward the cavity side wall of the second cavity 19.2.

[0050] In another embodiment provided by the present invention, the torque gear 21 includes an outer wheel ring 21.1 that is movably connected to the shaft roller 5.2, and an inner ring groove 21.2 is provided on the inner ring surface of the outer wheel ring 21.1. An inner ring ring 21.3 that is fixedly connected to the shaft roller 5.2 is adapted to rotate in the inner ring groove 21.2. An annular space is formed between the outer ring surface of the inner ring 21.3 and the bottom surface of the inner ring groove 21.2. In the annular space, a plurality of evenly distributed protrusions 21.4 are vertically fixed on the outer ring surface of the inner ring ring 21.3, and a plurality of evenly distributed hinge seats 21.5 are installed on the bottom surface of the inner ring groove 21.2. A plate body 21.6 is movably hinged on the hinge seat 21.5, and an arc-shaped guide rod 21.7 is movably passed through the side of the plate body 21.6. The center of the arc-shaped guide rod 21.7 is aligned with the plate body 21.6 at the hinge seat The deflection center of each of the two 21.5 coincides, and both ends of the arc guide rod 21.7 are fixed to the bottom surface of the inner ring groove 21.2. A first spring 21.8 and a second spring 21.9 are respectively provided on both sides of the plate body 21.6. The ends of the first spring 21.8 and the second spring 21.9 away from the plate body 21.6 are fixed to the bottom surface of the inner ring groove 21.2. The ends of the first spring 21.8 and the second spring 21.9 close to the plate body 21.6 are fixed to the plate body 21.6, so that when the plate body 21.6 is not subjected to external force, the longitudinal extension line of the plate body 21.6 passes through the axis of the shaft roller 5.2, and one end of the plate body 21.6 is located on the motion trajectory of the protruding block 21.4. A gear ring 22 meshing with the rack rod 20 is fixedly sleeved on the circumference of the outer ring 21.1;

[0051] During actual use, when the shaft roller 5.2 rotates forward, the inner ring 21.3 rotates synchronously and drives the protruding block 21.4 to move circumferentially. When the protruding block 21.4 contacts the plate body 21.6, the plate body 21.6, under the support of the first spring 21.8, causes the outer ring 21.1 to receive the driving force of the protruding block 21.4 and rotate in the same direction as the shaft roller 5.2. At this time, the rack rod 20 is driven by the meshing of the gear ring 22. When the rack rod 20 is blocked in its forward direction and cannot move further, the torque gear 21 slips forward. At this time, the resistance to the rotation of the gear ring 22 becomes greater. At this time, if the shaft roller 5.2 continues to rotate forward, the first spring 21.8 is compressed and deformed by the force. At the same time, the second spring 21.9 is pulled by the deflection of the plate body 21.6. The plate 21.6 is squeezed and separated from the motion trajectory of the protruding block 21.4. At this time, the shaft roller 5.2 rotates normally in the forward direction, and the outer ring 21.1 and the gear ring 22 remain stationary. Similarly, when the shaft roller 5.2 rotates in the reverse direction, when the rack rod 20 is blocked in its forward direction and cannot move further, the torque gear 21 slips in the reverse direction. At this time, the resistance to the rotation of the gear ring 22 becomes larger. At this time, if the shaft roller 5.2 continues to rotate in the reverse direction, the second spring 21.9 is compressed and deformed by the force. At the same time, the first spring 21.8 is stretched and deformed by the tension of the deflection of the plate 21.6, until the plate 21.6 is squeezed and separated from the motion trajectory of the protruding block 21.4. At this time, the shaft roller 5.2 rotates normally in the reverse direction, and the outer ring 21.1 and the gear ring 22 remain stationary.

[0052] It should be further explained that when the roller 5.2 rotates forward or backward, the corresponding first spring 21.8 and the second spring 21.9 will undergo opposite elastic deformation, so that during use, the first spring 21.8 and the second spring 21.9 both have the effect of elastic recovery, which is beneficial to avoid the situation where the first spring 21.8 and the second spring 21.9 undergo elastic deformation in only one direction, resulting in insufficient elastic recovery force, and is beneficial to maintaining the good elastic resistance effect of the first spring 21.8 and the second spring 21.9.

[0053] In another embodiment provided by the present invention, the monitoring device 4 includes a laser rangefinder 4.1 fixed to the rod column 3.1, a photoelectric receiving feedback unit 4.2 used in conjunction with the laser rangefinder 4.1 is fixed on the cone 1, and the feedback unit 4.2 includes a light shielding tube 23 fixedly connected to the top plane of the cone 1 concentrically, a laser receiving target 24 is fixed on the top plane of the cone 1 inside the light shielding tube 23, and a plurality of evenly distributed light holes 25 are opened on the same ring line in the circumferential direction of the light shielding tube 23, and the center line direction of the light shielding hole 25 is aligned with the center line direction of the light shielding tube 23. The angle between the lines is acute, and the center line direction of the light shielding tube 23 can coincide with the light of the laser rangefinder 4.1. In actual use, when the cone 1 falls and stops at a predetermined position, the laser emitted by the laser rangefinder 4.1 can just pass through the light hole 25 and illuminate the laser receiving target 24. The laser receiving target 24 is preferably annular in structure. The laser receiving target 24 feeds back the laser reception information to the display panel of the laser rangefinder 4.1, which indicates that the cone line 2 and the rod column 3.1 are in a vertical state, that is, the measured wall is parallel to the cone line 2.

[0054] In another embodiment provided by the present invention, an external threaded tube 26 is fixed to the top of the light-shielding tube 23, and the inner wall of the placement opening 5.1 is provided with a thread line that is spirally adapted to the external threaded tube 26. During actual use, when storage is required, when the cone 1 reaches the stop position on the rod column 3.1, the external threaded tube 26 is spirally connected to the placement opening 5.1, thereby facilitating storage and preventing the cone 1 from swinging around after storage.

[0055] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
