Description

Technical Field

[0001] The present invention relates to the technical field of laser detection, and particularly to a laser measurement and detection device for building construction and its usage method. Background Art

[0002] During the process of building construction, a vertical inspection ruler is used. The vertical inspection ruler, also known as a leveling ruler, is a detection tool with the highest usage frequency in the verticality detection, horizontality detection, and flatness detection of building object planes, and is used to detect whether the walls and ceilings are flat and vertical, and whether the floor joists are horizontal and flat.

[0003] However, the currently used vertical and horizontal ruler can only perform vertical or horizontal measurements on vertical walls and horizontal ceilings. For example, Figure 1 as shown, when using the vertical and horizontal ruler to measure the flatness of the ceiling of a house, the following deficiencies often exist:

[0004] 1. When measuring the flatness of a ridged house ceiling, it is often necessary to adjust the leveling ruler or electronic level according to the angle of the house ceiling. However, after the adjustment of the leveling ruler or electronic level is completed, it is often difficult to stably support the leveling ruler or electronic level, resulting in certain inconvenience when measuring the house ceiling.

[0005] 2. Furthermore, when measuring the flatness of a house ceiling as shown in Figure 1 , even if the leveling ruler or electronic level is set at a specific angle to measure the house ceiling, the position of the leveling ruler or electronic level is difficult to move, making it difficult to comprehensively measure the house ceiling.

[0006] In view of the above problems, the present invention document proposes a laser measurement and detection device for building construction and its usage method. Summary of the Invention

The support screw is in threaded connection with the driving nut.

[0021] The using method of the laser measurement and detection device for building construction includes the following steps:

[0022] S1. First, move the device into the room to be detected, and clamp the connecting plate on the moving frame through the two docking frames. Then, the docking frame and the moving frame can be stably connected by using the fixing bolt to pass through the plug hole.

[0023] S2. Then, drive the adjusting nut to rotate by pushing the first dial. At this time, under the action of the threaded transmission with the adjusting screw, the first adjusting plate can be driven to adjust the horizontal position, so that the first adjusting plate can be placed at an appropriate position according to the actual width of the house, and multiple side guide wheels can be kept in contact with the wall of the house.

[0024] S3. Then, when pushing the first moving plate in the direction close to the first fixed plate, it can drive the two first arc-shaped racks to move, separating the first arc-shaped racks from the corresponding first braking gears. At the same time, when moving the first moving plate, it can compress the first compression spring. After that, the first support cover can be rotated to adjust the rotation of the first infrared laser pen, and the angle of the first infrared laser pen can be adjusted to be consistent with the angle of the top surface of the house to be detected. After the angle adjustment of the first infrared laser pen is completed, the first moving plate can be released at this time. The first compression spring in the stressed state can push the first moving plate to reset in the reverse direction, so that the first arc-shaped rack can be engaged and braked with the corresponding first braking gear, thereby being able to position and brake the first infrared laser pen;

[0025] S4. Then, by horizontally moving the second adjusting plate, the position of the second infrared laser pen can be adjusted, so that when detecting the top surface of the house, the position of the second infrared laser pen can be adjusted according to actual needs. At the same time, by rotating the second support cover, the angle of the second infrared laser pen can be adjusted, and the support disk can also be adjusted. Therefore, when using the second infrared laser pen to irradiate and detect the top surface of the house, the position of the second infrared laser pen can be adjusted arbitrarily. After the adjustment is completed, the second moving plate can be released. The second compression spring in the stressed state can drive the second moving plate to move, making the second arc-shaped rack engaged with the corresponding second braking gear, thereby being able to position the set position of the second infrared laser pen. After moving the second infrared laser pen to the specified position, the synchronous belt can be pulled at this time. Then, with the transmission cooperation of the two synchronous wheels, the two transmission screws can be driven to rotate. When the transmission screws rotate, under the thread transmission action with the corresponding transmission nuts, the transmission screws can move downward, thereby driving the clamping plate to move downward. Then, with the cooperation of the clamping plate and the fixing ring, the second support tube can be positioned and clamped, so as to limit the position of the second adjusting plate. After that, by releasing the insertion rod, the tension spring in the stressed state can pull the insertion rod into the corresponding slot, thereby positioning the synchronous belt and further limiting the positions of the two clamping plates, enabling the clamping plate to be in a stable position and not change randomly. And when the linkage plate moves downward with the two transmission screws, it can drive the positioning plate to move downward, so that the positioning plate can be clamped with the corresponding card slot, thereby positioning and braking the support disk;

[0026] S5. Finally, by rotating the driving nut, under the thread transmission effect with the support screw rod, the moving frame can be driven to move longitudinally. At this time, when the moving frame moves upward, the first infrared laser pen and the second infrared laser pen can be moved to the specified height, and the inclined roof surface of the house can be detected. The set roller group can facilitate the movement of the overall device, so that when the limit frame is pushed horizontally, the two first infrared laser pens and the second infrared laser pen can be driven to move, so as to comprehensively detect the roof surface of the house. At the same time, the driving nut and the support screw rod have good self-locking properties. Therefore, after the first infrared laser pen and the second infrared laser pen are moved to the specified height, the first infrared laser pen and the second infrared laser pen can be limited.

[0027] It should be understood that the above general description and the following detailed description are only exemplary and do not limit the present invention.

[0028] Beneficial effects: In the present invention, through the set first detection mechanism, after the first infrared laser pen is installed in the first installation groove, the first support cover can be rotated and adjusted at this time. Therefore, when detecting the flatness of the inclined roof surface of the house, the first support cover can be rotated to be consistent with the angle of the roof surface of the house, so that the light emitted by the first infrared laser pen is parallel to the roof surface of the house and irradiates on the roof surface of the house. If there is a problem of uneven flatness on the roof surface of the house, the path of the light irradiation will be blocked. Therefore, the flatness of the house can be detected.

[0029] In the present invention, through the set second detection mechanism, the position of the second infrared laser pen can be adjusted by horizontally moving the second adjustment plate. Therefore, when detecting the roof surface of the house, the position of the second infrared laser pen can be adjusted according to actual needs. At the same time, the angle of the second infrared laser pen can be adjusted by rotating the second support cover, and the support disk can also be adjusted. Therefore, when using the second infrared laser pen to irradiate and detect the roof surface of the house, the position of the second infrared laser pen can be adjusted arbitrarily. After the adjustment is completed, the second moving plate can be released. At this time, the second compression spring in the stressed state can drive the second moving plate to move, so that the second arc-shaped rack is engaged with the corresponding second brake gear, so as to realize the positioning of the set position of the second infrared laser pen.

[0030] In the present invention, through the provided support mechanism, the connecting plate can be clamped on the moving frame through two docking frames, and then the docking frame and the moving frame can be stably connected by passing the fixing bolts through the jacks. Moreover, the moving frame is slidably connected to the two limiting frames. Therefore, by longitudinally pushing the moving frame, the height of the connecting plate can be adjusted, so as to conveniently adjust the heights of the two first infrared laser pens and the second infrared laser pen. In addition, the provided roller group can facilitate the movement of the overall device, such that by laterally pushing the limiting frame, the two first infrared laser pens and the second infrared laser pen can be driven to move, so as to comprehensively detect the top surface of the house.

[0031] The present invention can detect the flatness of the top surface of a house in an inclined state, so that in actual use, it can quickly and comprehensively detect the top surface of the house. Therefore, in actual use, it has good convenience in use. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] The embodiments of the present invention will be described below with reference to the accompanying drawings in the embodiments of the present invention.

[0043] In the description of the embodiments of the present invention, it should be noted that unless otherwise clearly defined and limited, the terms "connection" and "installation" should be understood in a broad sense. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. In addition, "communication" can be a direct communication or an indirect communication through an intermediate medium. Among them, "fixing" means that they are connected to each other and the relative position relationship after connection remains unchanged. The orientation terms mentioned in the embodiments of the present invention, such as "inside", "outside", "top", "bottom", etc., are only references to the directions of the accompanying drawings. Therefore, the orientation terms used are for better and clearer description and understanding of the embodiments of the present invention, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the embodiments of the present invention.

[0044] Example 1: Refer to Figures 1 - 8, a detection device, which includes a bracket composed of a first support tube 1, two second support tubes 2 and two connecting plates 3. The two second support tubes 2 are symmetrically arranged on both sides of the first support tube 1. The first support tube 1 penetrates through the two connecting plates 3 respectively and is fixedly connected to them. At the same time, the second support tube 2 also penetrates through the two connecting plates 3 and is fixedly connected to them. Inside the second support tube 2, two limiting rods 4 are symmetrically and slidably connected, and the mutually remote ends of the two limiting rods 4 extend to both sides of the second support tube 2 respectively.

[0045] As Figure 3 shown, in order to detect the flatness of the top surface of an inclined house, the device further includes two first detection mechanisms. The two first detection mechanisms are respectively connected to one end of the corresponding two limiting rods 4. Each first detection mechanism includes a first adjustment plate 5, which is fixedly connected to the corresponding limiting rod 4. On the top of the first adjustment plate 5, a first support frame 7 is fixedly installed, and a first support shaft 8 is fixedly connected inside the first support frame 7. A first support cover 9 is rotatably sleeved on the first support shaft 8, and a first installation groove 10 is opened at the top of the first support cover 9. Inside the first installation groove 10, a first fixing plate 11 is fixedly installed, and a first infrared laser pen 12 is fixedly installed through the first fixing plate 11. This first infrared laser pen 12 is used to irradiate the top surface of the inclined house to detect the flatness of the top surface of the house. After the first infrared laser pen 12 is installed in the first installation groove 10, the first support cover 9 can be rotationally adjusted so that when detecting the top surface of the inclined house, the first support cover 9 can be rotated to be at the same angle as the top surface of the house, so that the light emitted by the first infrared laser pen 12 is parallel to the top surface of the house. If there is a problem of uneven flatness on the top surface of the house, the path of the light irradiation will be blocked, thus realizing the detection of the flatness of the house.

[0046] As Figure 3As shown in the figure, in order to facilitate the adjustment of the angle of the first infrared laser pen 12, a first moving plate 13 is slidably sleeved on the first infrared laser pen 12. First sliding holes are formed in the inner walls on both sides of the first installation groove 10. The two sides of the first moving plate 13 respectively penetrate through the corresponding first sliding holes and extend to both sides of the first support cover 9. On one side of the first moving plate 13, first arc-shaped racks 14 are symmetrically and fixedly installed on both sides of the first support cover 9 respectively, and two first braking gears 15 are symmetrically and fixedly sleeved on the first support shaft 8 on both sides of the first support cover 9 respectively. These first arc-shaped racks 14 are engaged with the corresponding first braking gears 15. In addition, a first compression spring 16 is sleeved on the first infrared laser pen 12 between the first fixing plate 11 and the first moving plate 13. The two ends of the first compression spring 16 are respectively fixedly connected to the sides of the first fixing plate 11 and the first moving plate 13 close to each other. When the first moving plate 13 is pushed close to the first fixing plate 11, the two first arc-shaped racks 14 can be driven to move, so that they are separated from the corresponding first braking gears 15. At this time, the first support cover 9 can be rotated to adjust the angle of the first infrared laser pen 12. After the adjustment is completed, the first moving plate 13 is released, and the first compression spring 16 in the stressed state will push the first moving plate 13 to reset in the reverse direction, so that the first arc-shaped rack 14 is re-engaged and braked with the corresponding first braking gear 15, thereby fixing the position of the first infrared laser pen 12.

[0047] As Figure 8 shown, in order to adjust the position of the first infrared laser pen 12 according to the width of the house, an adjusting screw 25 is fixedly installed on the side of the first adjusting plate 5 close to the connecting plate 3. A adjusting nut 251 is rotatably connected to the side of the connecting plate 3 close to the first adjusting plate 5, and a first dial 252 is fixedly sleeved on the adjusting nut 251. One end of the adjusting screw 25 penetrates through the adjusting nut 251 and the connecting plate 3 and extends into the first support tube 1, and is threadedly connected to the adjusting nut 251. At the same time, a plurality of side guide wheels 6 are rotatably connected at equal intervals on the side of the first adjusting plate 5 away from the connecting plate 3. By rotating the first dial 252 to drive the adjusting nut 251 to rotate, the first adjusting plate 5 can be driven to perform lateral position adjustment under the threaded driving action of the adjusting screw 25. In this way, the first adjusting plate 5 can be adjusted to a suitable position according to the actual width of the house, so that the plurality of side guide wheels 6 are in contact with the wall surface of the house, thereby adjusting the position of the first infrared laser pen 12 and facilitating its irradiation detection of the inclined house top surface.

[0048] As Figure 5As shown, the device further includes a second detection mechanism, which includes a second adjusting plate 17 that is slidably sleeved on the first support tube 1 and two second support tubes 2 respectively. A support disk 18 is rotatably connected to the top of the second adjusting plate 17, and two card slots are symmetrically formed on the support disk 18. A second support frame 19 is fixedly installed on the top of the support disk 18, and a second support shaft 20 is fixedly installed inside the second support frame 19. A second support cover 21 is rotatably sleeved on the second support shaft 20, and a second installation groove 22 is formed on the top of the second support cover 21. Inside the second installation groove 22, a second fixing plate 23 is fixedly installed, and a second infrared laser pen 24 is fixedly installed through the second fixing plate 23. One end of the second infrared laser pen 24 is fixedly connected to one inner wall of the second installation groove 22. By horizontally moving the second adjusting plate 17, the position of the second infrared laser pen 24 can be adjusted so as to adjust its position according to actual needs when detecting the top surface of a house. At the same time, the angle of the second infrared laser pen 24 can be adjusted by rotating the second support cover 21.

[0049] As Figure 4 shown, in order to facilitate fixing the position of the second adjusting plate 17, two fixing rings 30 are symmetrically and fixedly installed on one side of the second adjusting plate 17, and the two fixing rings 30 are respectively sleeved on the two second support tubes 2. A moving groove 31 is formed on the inner wall of the top of the fixing ring 30, and a clamping plate 32 is slidably connected in the moving groove 31 for clamping and limiting the second support tube 2. A transmission nut 33 is fixedly installed on the top of the fixing ring 30, and a transmission screw 34 is threadedly connected inside the transmission nut 33. The bottom end of the transmission screw 34 extends into the corresponding moving groove 31 and is connected to the corresponding clamping plate.

[0050] This application can be used in the field of building detection technology and can also be used in other fields applicable to this application.

[0051] Example 2: Refer to Figure 7, improved on the basis of Embodiment 1: A laser measurement and detection device for building construction, which is applied to the field of building detection technology. The device further includes a support mechanism for adjusting the height position and lateral position of the connecting plate 3. The support mechanism includes a roller group 42, and two limit frames 43 are symmetrically and fixedly installed on the top thereof. The same moving frame 44 is slidably connected within the two limit frames 43. Insertion holes 50 are formed in the inner walls of the top portions on both sides of the moving frame 44. The support mechanism further includes two docking frames 49 symmetrically and fixedly installed at the bottom of the connecting plate 3. The top of the moving frame 44 extends into the two docking frames 49, and a fixing bolt 51 is connected to the docking frame 49. The fixing bolt 51 penetrates through the corresponding insertion hole 50 and is connected to the inner wall of the insertion hole 50. After the connecting plate 3 is clamped on the moving frame 44 through the two docking frames 49, the docking frame 49 and the moving frame 44 can be stably connected by using the fixing bolt 51 to pass through the insertion hole 50. Since the moving frame 44 is slidably connected to the two limit frames 43, the height of the connecting plate 3 can be adjusted by longitudinally pushing the moving frame 44, so as to conveniently adjust the heights of the two first infrared laser pens 12 and the second infrared laser pen 24. The provided roller group 42 facilitates the movement of the whole device. Transversely pushing the limit frame 43 can drive the two first infrared laser pens 12 and the second infrared laser pen 24 to move, so as to comprehensively detect the top surface of the house.

[0052] To facilitate the adjustment of the height of the moving frame 44, a support screw 48 is fixedly installed on the top of the roller group 42, and the same reinforcing plate 45 is fixedly installed on the top of the two limit frames 43. The moving frame 44 penetrates through the reinforcing plate 45 and is slidably connected to the reinforcing plate 45. A driving nut 46 is rotatably connected to the bottom thereof. A second dial 47 is fixedly sleeved on the driving nut 46. The top end of the support screw 48 penetrates through the driving nut 46 and the moving frame 44 and is fixedly connected to the bottom of the reinforcing plate 45. The support screw 48 is in threaded connection with the driving nut 46. By rotating the second dial 47 to drive the driving nut 46 to rotate, the moving frame 44 can be driven to move longitudinally under the action of the threaded transmission with the support screw 48. When the moving frame 44 moves upward, after the first infrared laser pen 12 and the second infrared laser pen 24 are moved to the specified height, the first infrared laser pen 12 and the second infrared laser pen 24 can be limited.

[0053] The present invention provides a method for using a laser measurement and detection device for building construction, including the following steps:

[0054] S1. First, move the device into the room to be detected, and clamp the connecting plate 3 on the moving frame 44 through the two docking frames 49. Then, the docking frame 49 and the moving frame 44 can be stably connected by using the fixing bolt 51 to pass through the insertion hole 50;

[0055] S2. Next, by pushing the first dial wheel 252 to drive the adjusting nut 251 to rotate, at this time, under the threaded drive of the adjusting screw 25, the first adjusting plate 5 can be driven to adjust the horizontal position, so that the first adjusting plate 5 can be placed at an appropriate position according to the actual width of the house, and multiple side guide wheels 6 can be kept in contact with the wall of the house;

[0056] S3. Then, when pushing the first moving plate 13 in the direction close to the first fixing plate 11, the two first arc-shaped racks 14 can be driven to move, so that the first arc-shaped rack 14 is separated from the corresponding first braking gear 15. At the same time, when moving the first moving plate 13, the first compression spring 16 can be compressed. After that, the first support cover 9 can be rotated to adjust the rotation of the first infrared laser pen 12, and the angle of the first infrared laser pen 12 can be adjusted to be consistent with the angle of the top surface of the house to be detected. After the angle adjustment of the first infrared laser pen 12 is completed, the first moving plate 13 can be released at this time. The first compression spring 16 in the stressed state can push the first moving plate 13 to reset in the reverse direction, so that the first arc-shaped rack 14 can be engaged and braked with the corresponding first braking gear 15, thereby being able to position and brake the first infrared laser pen 12;

[0057] S4. Then, by horizontally moving the second adjusting plate 17, the position of the second infrared laser pen 24 can be adjusted. In this way, when detecting the top surface of the house, the position of the second infrared laser pen 24 can be adjusted according to actual needs. At the same time, by rotating the second support cover 21, the angle of the second infrared laser pen 24 can be adjusted, and the support disc 18 can also be adjusted. Therefore, when using the second infrared laser pen 24 to irradiate and detect the top surface of the house, the position of the second infrared laser pen 24 can be adjusted arbitrarily. After the adjustment is completed, the second moving plate 26 can be released. At this time, the second compression spring 29 in the stressed state can drive the second moving plate 26 to move, so that the second arc-shaped rack 27 and the corresponding second brake gear 28 are in the meshing state, thereby realizing the positioning of the set position of the second infrared laser pen 24. After moving the second infrared laser pen 24 to the specified position, the synchronous belt 36 can be pulled at this time. Then, under the transmission cooperation with the two synchronous wheels 35, the two transmission screws 34 can be driven to rotate. When the transmission screws 34 rotate, under the thread transmission action with the corresponding transmission nuts 33, the transmission screws 34 can move downward, thereby driving the clamping plate 32 to move downward. In this way, by using the cooperation of the clamping plate 32 and the fixed ring 30, the second support tube 2 can be positioned and clamped, so as to realize the limitation of the position of the second adjusting plate 17. After that, by releasing the insertion rod 38, the tension spring 39 in the stressed state can pull the insertion rod 38 into the corresponding slot, thereby positioning the synchronous belt 36, further limiting the positions of the two clamping plates 32, and enabling the clamping plate 32 to be in a stable position and not change randomly. And when the linkage plate 40 moves downward with the two transmission screws 34, the positioning plate 41 can be driven to move downward. In this way, by using the positioning plate 41 to be clamped with the corresponding card slot, the support disc 18 can be positioned and braked;

[0058] S5. Finally, by rotating the driving nut 46 under the thread transmission action with the support screw 48, the moving frame 44 can be driven to move longitudinally. At this time, when the moving frame 44 moves upward, the first infrared laser pen 12 and the second infrared laser pen 24 can be moved to the specified height to detect the inclined top surface of the house. And the set roller group 42 can facilitate the overall device to move, so that when the limiting frame 43 is pushed horizontally, the two first infrared laser pens 12 and the second infrared laser pen 24 can be driven to move, so as to comprehensively detect the top surface of the house. At the same time, the driving nut 46 and the support screw 48 have good self-locking properties. Therefore, after moving the first infrared laser pen 12 and the second infrared laser pen 24 to the specified height, the first infrared laser pen 12 and the second infrared laser pen 24 can be limited.

[0059] However, as is well known to those skilled in the art, the working principles and wiring methods of the first infrared laser pointer 12 and the second infrared laser pointer 24 are common knowledge and belong to conventional means or well-known common sense. Therefore, they will not be elaborated here. Those skilled in the art can make arbitrary selections according to their needs or convenience.

[0060] The above is only the specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention; without conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.
