Description

Technical Field

[0001] The present invention relates to the technical field of construction engineering, and in particular to a construction engineering laser detection device and a method thereof. Background Art

[0002] In construction projects, since indoor walls and ceilings are usually whitewashed manually, manual whitewashing may result in poor flatness of the wall or ceiling. In order to ensure the quality of the whitewashed wall, it is necessary to measure the flatness of the wall and ceiling after whitewashing, and promptly repair the position with poor flatness. In the process of measuring the flatness of walls and ceilings, laser ranging is a commonly used measuring instrument. It adopts non-contact measurement, which not only does not affect the wall, but also has fast measurement response speed and high accuracy. It is widely used in the flatness measurement of walls. However, before using the laser detector for measurement, protective glasses are required to avoid laser refraction during the laser detector's detection of flatness, thereby directly irradiating the eyes and causing eye injuries to the user. In the process of pushing the laser detector to use the slide rail for mobile detection, due to the large number of foreign matter and impurities in the construction site, they accumulate in the slide rail and cause blockage. At the same time, after the use of the laser detector, the user needs to manually wipe the laser emission point of the laser detector, which is time-consuming and laborious. Summary of the invention

[0026] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0027] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0029] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0030] Reference Figures 1 to 6 , which is the first embodiment of the present invention, provides a method for using a laser detection device for construction projects. Through the method for using a laser detection device for construction projects, it is possible to block part of the laser with a larger refracted angle during the startup process and wipe it synchronously. During the shutdown process, it is possible to not only wipe again but also blow away foreign matter in the slide rail 101.

[0031] When the laser detection mechanism 100 is started for detection, the second piston rod 205 moves upward to inject gas into the thin gas cylinder 202 to start the laser blocking mechanism 200 to cover the laser emission position of the laser detector 106 and the space where the laser is refracted, thereby blocking part of the laser with a larger refraction angle; At the same time, the wiping mechanism 300 is activated to drive the wiping cotton 304 to perform the first step of wiping the laser emitting part of the laser detector 106, so that the laser detector 106 is cleaned before emitting the laser, thereby ensuring the laser emitting effect of the laser detector 106; During the process of closing the laser detection mechanism 100, the cleaning mechanism 400 will be activated to blow out air to remove foreign matter and impurities pushed by the slide bar 103 inside the slide rail 101. At the same time, the laser emission point of the used laser detector 106 will be wiped in a second step to facilitate the next use of the laser detector 106.

[0032] Reference Figures 1 to 6 , which is the second embodiment of the present invention, provides a wiping mechanism 300. Through the wiping mechanism 300, the laser detector 106 can be driven by the wiping mechanism 300 to wipe and clean the laser emission point of the laser detector 106 when it is started or shut down.

[0033] The wiping mechanism 300 includes a connecting frame 301, the left side of the connecting frame 301 is fixedly connected to the bottom of the right side of the laser detector 106, the connecting frame 301 is internally slidably connected to a transmission frame 302, the right side of the inner side of the transmission frame 302 is fixedly connected to a second tension spring 303, the other end of the second tension spring 303 is fixedly connected to the top of the right side of the connecting frame 301, the left side of the bottom of the transmission frame 302 is fixedly connected to a wiping cotton 304, the transmission frame 302 is T-shaped, the right side of the transmission frame 302 is fixedly connected to a pulling rope 305, the other end of the pulling rope 305 is fixedly connected to the bottom of the right side of the protective cover, the right side of the connecting frame 301 is fixedly connected to a guide assembly 306, and both sides of the left side of the top of the transmission frame 302 are fixedly connected to blowing assemblies 307.

[0034] The guide assembly 306 includes a guide frame 306a, the left side of the guide frame 306a is fixedly connected to the right side of the connecting frame 301, the inner wall of the guide frame 306a is slidably connected to the surface of the pulling rope 305, and a rounded guide groove 306b is opened on the right side of the guide frame 306a, and the inner wall of the rounded guide groove 306b is slidably connected to the surface of the pulling rope 305.

[0035] The blowing assembly 307 includes a second nozzle 307a, the inner side of the second nozzle 307a is fixedly connected to the two sides of the left side of the top of the transmission frame 302, and a four-end air guide pipe 307b is arranged on the right side of the bottom of the laser blocking cover 201, and the two ends of the four-end air guide pipe 307b away from the laser blocking cover 201 are connected to the top of the right side of the rough air cylinder 204, and the two ends of the four-end air guide pipe 307b away from the rough air cylinder 204 are connected to the top of the second nozzle 307a, and the two sides of the top of the inner wall of the rough air cylinder 204 are fixedly connected with air separation components 307c.

[0036] The air separation component 307c includes an air flow splitting plate 307c-1, the top of the air flow splitting plate 307c-1 is fixedly connected to both sides of the top of the inner wall of the rough air cylinder 204, the inner side of the air flow splitting plate 307c-1 is slidingly connected to the surface of the second piston rod 205, and fitting grooves 307c-2 are provided on both sides of the top of the second piston rod 205.

[0037] Specifically, when the laser blocking cover 201 is pushed, the wiping cotton 304 will be driven to wipe the laser emission point of the laser detector 106, so that the detection accuracy of the laser detector 106 during use is improved. After the laser blocking cover 201 moves to the maximum distance, the wiping cotton 304 will be on one side of the laser detector 106. At the same time, the transmission frame 302 is set in a T shape, so as to ensure that the position of the transmission frame 302 will not block the laser emission after the laser detector 106 is cleaned. During the resetting process of the laser blocking cover 201, the pull rope 305 will be pulled to drive the wiping cotton 304 to reset and wipe the laser emission point of the laser detector 106 again, so as to facilitate the next use of the laser detector 106.

[0038] Specifically, when the lifting rope 305 is pulled, the guide frame 306a can maintain the pulling angle of the lifting rope 305 and guide the pulling angle of the lifting rope 305. At the same time, the rounded guide groove 306b can limit the front and rear positions of the lifting rope 305 to prevent the lifting rope 305 from detaching, thereby ensuring the pulling direction of the lifting rope 305 and avoiding the situation where the lifting rope 305 cannot be pulled.

[0039] Specifically, the second nozzle 307a can spray out excess air, so that when the wiping cotton 304 wipes the laser emission point of the laser detector 106, it can first use the second nozzle 307a to blow off the loose dust on the surface of the laser emission point, further improving the wiping and cleaning effect.

[0040] Specifically, the air flow splitting plate 307c-1 can be used to divide the air pushed upward by the second piston rod 205, ensuring the uniformity of air diversion, while ensuring that sufficient air enters the inner part of the fine air cylinder 202 without affecting the injection of the second nozzle 307a. When the second piston rod 205 moves upward to the top, the bottom of the air flow splitting plate 307c-1 will be inserted into the fitting groove 307c-2, thereby ensuring the air sealing on one side of the fine air cylinder 202.

[0041] Furthermore, when the laser blocking cover 201 is pushed, the pulling rope 305 will gradually loosen, so that the tension of the second tension spring 303 is released, and then the second tension spring 303 will pull the transmission frame 302 to move along the inner wall of the connecting frame 301, and then the transmission frame 302 will drive the wiping cotton 304 to wipe the laser emission point of the laser detector 106, and after the laser blocking cover 201 moves to the maximum distance, the wiping cotton 304 will be on one side of the laser detector 106, and at the same time, the transmission frame 302 will drive the wiping cotton 304 to wipe the laser emission point of the laser detector 106. The frame 302 is set in a T shape, so as to ensure that the position of the transmission frame 302 will not block the laser emission after the laser detector 106 is cleaned. During the resetting process of the laser blocking cover 201, the pull rope 305 will be pulled, so that the pull rope 305 pulls the transmission frame 302 to reset. Then the transmission frame 302 will drive the wiping cotton 304 to reset and wipe the laser emission point of the laser detector 106 again to facilitate the next use of the laser detector 106. At the same time, the second tension spring 303 is pulled to generate tension.

[0042] Furthermore, when the lifting rope 305 is pulled, the guide frame 306a can be used to support the lifting rope 305, so that the pulling angle of the lifting rope 305 can be maintained and guided. At the same time, the rounded guide groove 306b can be used to limit the front and rear positions of the lifting rope 305 to prevent the lifting rope 305 from detaching, thereby ensuring the pulling direction of the lifting rope 305 and avoiding the situation where the lifting rope 305 cannot be pulled.

[0043] Furthermore, when the laser blocking cover 201 is driven by the air pushed by the second piston rod 205, the excess air inside the coarse air cylinder 204 can be conducted to the inside of the second nozzle 307a through the four-end air guide tube 307b, and then the second nozzle 307a can spray out the excess air, so that the wiping cotton 304 can first use the second nozzle 307a to blow off the loose dust on the surface of the laser emission point during wiping the laser emission point of the laser detector 106, thereby further improving the wiping and cleaning effect.

[0044] Furthermore, the air flow splitting plate 307c-1 can be used to divide the air pushed upward by the second piston rod 205, thereby ensuring uniformity of air diversion. When the air inside the thin air cylinder 202 is sufficient, the air originally diverted to one side of the thin air cylinder 202 will be pushed into the four-end air guide tube 307b, thereby ensuring that sufficient air enters the inside of the thin air cylinder 202 without affecting the injection of the second nozzle 307a. When the second piston rod 205 moves upward to the top, the bottom of the air flow splitting plate 307c-1 will be inserted into the fitting groove 307c-2, thereby ensuring the air sealing on one side of the thin air cylinder 202.

[0045] Reference Figures 1 to 6 , which is the third embodiment of the present invention, provides a cleaning mechanism 400. Through the cleaning mechanism 400, an airflow is generated during the closing process of the laser detection mechanism 100 and the laser blocking mechanism 200, and the airflow is sprayed out through the cleaning mechanism 400 to blow away the impurities and foreign objects in the slide rail 101.

[0046] The cleaning mechanism 400 includes a first nozzle 401, the inner side of the first nozzle 401 is fixedly connected to the left and right sides of the connecting plate 102, the bottom of the first nozzle 401 is connected to a guide air pipe 402, the bottom of the outer side of the rough air cylinder 204 is connected to a three-end air guide pipe 403, and the two ends of the three-end air guide pipe 403 away from the rough air cylinder 204 are connected to the top of the first nozzle 401.

[0047] Specifically, when the electric telescopic rod 104 drives the laser detector 106 to move downward and reset through the bottom plate 105, the bottom plate 105 will push the second piston rod 205 downward, so that the air in the lower half of the rough air cylinder 204 will be pushed downward, so that the air enters the first nozzle 401 through the three-end air guide pipe 403, and then the first nozzle 401 will spray air through the guide air pipe 402, thereby pushing the foreign matter and impurities pushed to one side of the slide bar 103 out of the slide rail 101, so that the interior of the slide rail 101 can be cleaned, avoiding the situation where excessive accumulation of foreign matter and impurities inside the slide rail 101 causes jamming and blockage, thereby improving the smoothness of the slide rail 101 and the slide bar 103 for the next use.

[0048] Furthermore, when the user pushes the electric telescopic rod 104 to drive the laser detector 106 to move to one side for detection, the slide bar 103 will be driven to move inside the slide rail 101. The slide rail 101 is used at a construction site. Some foreign matter and impurities in the construction site will enter the slide rail 101 and be pushed to one side by the slide bar 103. When the slide bar 103 is completely pushed to one side, the flatness of the current wall or ceiling is detected. Then the user can use the electric telescopic rod 104 to drive the laser detector 106 through the bottom plate 105. The device 106 moves downward to reset, and at the same time, the bottom plate 105 pushes the second piston rod 205 downward, so that the air in the lower half of the rough air cylinder 204 is pushed downward, so that the air enters the first nozzle 401 through the three-end air guide pipe 403, and then the first nozzle 401 sprays the air through the guide air pipe 402, so as to push the foreign matter and impurities on one side of the slide bar 103 out of the slide rail 101, so as to clean the inside of the slide rail 101 and avoid the situation where the foreign matter and impurities inside the slide rail 101 are stuck and blocked due to excessive accumulation of foreign matter and impurities.

[0049] The remaining structure is the same as that of Example 2.

[0050] Reference Figures 1 to 6 , which is the fourth embodiment of the present invention. This embodiment is different from the third embodiment in that: this embodiment provides a laser detection device for construction engineering.

[0051] When the user needs to measure the flatness of the ceiling, the user can directly start the electric telescopic rod 104 to drive the base plate 105 to move upward, and then the base plate 105 will drive the laser detector 106 to move upward close to the ceiling. Then the laser detector 106 will be started to emit a laser beam. After the laser beam is irradiated on the ceiling, it will be refracted immediately, and the refracted laser will be received by the laser detector 106. If the refracted laser can be received, it means that the current position is flat enough. If the refracted laser cannot be received, it means that the current position is not flat enough and there are protrusions or depressions.

[0052] When the user needs to measure the flatness of the wall, the user can directly pull the plug rod 108 to pull the first tension spring 110, and at the same time the bottom plate 105 loses its position, and then the bottom plate 105 can be rotated downward by ninety degrees to drive the laser detector 106 to rotate ninety degrees. At the same time, the electric telescopic rod 104 can be used to limit the maximum activity space of the laser detector 106 to avoid excessive rotation angle. Then the electric telescopic rod 104 is started to drive the bottom plate 105 to move upward, and then the bottom plate 105 will drive the laser detector 106 to move upward to adapt to the height of the wall that needs to be detected. Then the laser detector 106 is started to emit a laser beam. After the laser beam is irradiated on the wall, it will be refracted immediately, and the refracted laser will be received by the laser detector 106. If the refracted laser can be received, it means that the current position is flat enough. If the refracted laser cannot be received, it means that the current position is not flat enough and there are protrusions or depressions.

[0053] In the process of the electric telescopic rod 104 driving the bottom plate 105 to move upward, the bottom plate 105 will drive the second piston rod 205 to move upward to extract air. At this time, the air inside the thick air cylinder 204 will be pushed upward, and then the air will enter the thin air cylinder 202 through the hose, so that the first piston rod 203 inside the thin air cylinder 202 will move under the action of the air push, and then the first piston rod 203 will push the laser blocking cover 201 to move, and then the laser blocking cover 201 will cover the laser emitting part of the laser detector 106 and the space for laser refraction, so that part of the laser with a larger refraction angle can be prevented from irradiating the user's eyes. At the same time, the diameter of the thin air cylinder 202 is smaller than that of the thick air cylinder 204, so that the amount of air pushed by the second piston rod 205 when it moves a short distance upward is sufficient to The laser blocking cover 201 is completely pushed out, which improves the adaptability of the laser blocking cover 201 to different heights. During the pushing process of the first piston rod 203, the driving force of the first piston rod 203 itself and part of the driving force are distributed to the force equalizing plate 206a through the inclined rod 206b, and then the force equalizing plate 206a will push the laser blocking cover 201 to move, thereby ensuring the stability of the movement of the laser blocking cover 201. At the same time, during the movement of the laser blocking cover 201, the limit block 207b will be driven to move along the inner wall of the limit groove 207a. The sliding cooperation between the limit block 207b and the limit groove 207a can limit the movement of the laser blocking cover 201 front, back, left and right, which can further ensure the stability of the laser blocking cover 201 in a certain process and avoid tilting and tipping during the movement.

[0054] However, when the laser blocking cover 201 is pushed, the pulling rope 305 will gradually loosen, so that the tension of the second tension spring 303 is released, and then the second tension spring 303 will pull the transmission frame 302 to move along the inner wall of the connecting frame 301, and then the transmission frame 302 will drive the wiping cotton 304 to wipe the laser emission point of the laser detector 106, and after the laser blocking cover 201 moves to the maximum distance, the wiping cotton 304 will be on one side of the laser detector 106, and the transmission frame 302 is set in a T shape, so as to ensure that the position of the transmission frame 302 will not block the laser emission after the laser detector 106 is cleaned.

[0055] While the laser blocking cover 201 is driven by the air pushed by the second piston rod 205, the excess air inside the rough air cylinder 204 can be conducted to the inside of the second nozzle 307a through the four-end air duct 307b, and then the second nozzle 307a can spray out the excess air, so that the wiping cotton 304 can first use the second nozzle 307a to blow off the loose dust on the surface of the laser emission point during wiping the laser emission point of the laser detector 106, thereby further improving the wiping and cleaning effect.

[0056] At the same time, the air flow splitting plate 307c-1 can divide the air pushed upward by the second piston rod 205 to ensure the uniformity of air diversion. When the air inside the thin air cylinder 202 is sufficient, the air originally diverted to one side of the thin air cylinder 202 will be pushed into the four-end air guide tube 307b, so that the second nozzle 307a will not be affected when sufficient air enters the inside of the thin air cylinder 202. When the second piston rod 205 moves upward to the top, the bottom of the air flow splitting plate 307c-1 will be inserted into the fitting groove 307c-2, thereby ensuring the air sealing on one side of the thin air cylinder 202.

[0057] When the user pushes the electric telescopic rod 104 to drive the laser detector 106 to move to one side for detection, the slide bar 103 will be driven to move inside the slide rail 101. The slide rail 101 is used at a construction site. Some foreign matter and impurities in the construction site will enter the slide rail 101 and be pushed to one side by the slide bar 103. When the slide bar 103 is completely pushed to one side, the flatness of the current wall or ceiling is detected. Then the user can use the electric telescopic rod 104 to drive the laser detector 106 through the bottom plate 105. 6 moves downward to reset, and at the same time, the bottom plate 105 pushes the second piston rod 205 downward, so that the air in the lower half of the rough air cylinder 204 is pushed downward, so that the air enters the first nozzle 401 through the three-end air guide pipe 403, and then the first nozzle 401 sprays the air through the guide air pipe 402, so as to push the foreign matter and impurities pushed to one side of the slide bar 103 out of the slide rail 101, so as to clean the inside of the slide rail 101 and avoid the jamming and blockage caused by excessive accumulation of foreign matter and impurities in the slide rail 101.

[0058] The air extracted during the downward movement of the second piston rod 205 will enter the interior of the coarse air cylinder 204 through the fine air cylinder 202 and the second nozzle 307a, thereby ensuring sufficient air supply. At this time, the air inside the fine air cylinder 202 will be discharged, causing the first piston rod 203 to reset, and then the first piston rod 203 will drive the laser blocking cover 201 to reset.

[0059] During the resetting process of the laser blocking cover 201, the pulling rope 305 will be pulled, so that the pulling rope 305 pulls the transmission frame 302 to reset, and then the transmission frame 302 will drive the wiping cotton 304 to reset and wipe the laser emission point of the laser detector 106 again to facilitate the next use of the laser detector 106. At the same time, the second tension spring 303 is pulled to generate tension. During the pulling process of the pulling rope 305, the guide frame 306a can be used to support the pulling rope 305, so as to maintain the pulling angle of the pulling rope 305 and guide the pulling angle of the pulling rope 305. At the same time, the rounded guide groove 306b can be used to limit the front and rear positions of the pulling rope 305 to prevent the pulling rope 305 from detaching, thereby ensuring the pulling direction of the pulling rope 305 and avoiding the situation where it cannot be pulled.

[0060] In summary, in the process of using the laser detection mechanism 100 for detection, the laser blocking mechanism 200 will be driven to cover the position of the laser emission and the space of the laser refraction, and the wiping mechanism 300 will be started to wipe the laser emission point of the laser detection mechanism 100, so as to ensure the stability and accuracy of the laser emission. In the process of closing the laser detection mechanism 100, the wiping mechanism 300 will be started to wipe again, and the cleaning mechanism 400 will be started to clean the inside of the slide rail 101.
