Description

Technical Field

[0001] This invention relates to the field of laser measurement technology, and in particular to a verticality laser detection device for 3D scanning and mapping. Background Technology

[0002] Laser equipment used for verticality detection in 3D scanning and mapping is an advanced detection system that integrates laser scanning, 3D modeling and high-precision comparative analysis. It is widely used in fields such as construction, wind power, bridges, and industrial equipment installation, and is especially suitable for rapid, non-contact, and high-precision measurement of the verticality of tall structures (such as wind turbine towers, bridge piers, curtain wall columns, etc.). However, existing technologies still have the following problems: While verticality laser inspection equipment has a telescopic height adjustment function to better adapt to complex structures and height changes, this function uses an electric lead screw for telescopic adjustment. To ensure high-precision telescopic adjustment, the lead screw itself is made of high-strength alloy steel. This material, combined with the other electric telescopic structure, results in a heavy overall weight, making it inconvenient to carry. Furthermore, the electric lead screw itself is a "single nut-lead screw pair," providing only one stroke. To achieve two or three stages of telescopic movement, the lead screw mechanism is usually made into a "multi-level nested" or "lead screw + synchronous belt / chain" composite scheme, further complicating the overall structure and increasing its weight, thus sacrificing portability and the original advantage of portability. Therefore, we propose a verticality laser inspection device for 3D scanning and mapping. Summary of the Invention

[0008] Optionally, the transmission switching component includes a first connector, a second connector, and a first bevel gear.

A through hole is provided in the middle of one of the first drive gears. One of the output shafts of the dual-axis servo motor is located inside the through hole.

[0009] Optionally, a second bevel gear is engaged with one side of the first connector, a positioning sleeve is rotatably connected to one side of the second bevel gear, and the first bevel gear is rotatably mounted on the outside of the positioning sleeve.

[0010] Optionally, the transmission component includes multiple sets of second drive gears, and multiple sets of drive grooves are formed around the upper end of the first telescopic cylinder. The second drive gear is rotatably installed inside the drive groove. A gear groove corresponding to the second drive gear is formed on the outer side of the second telescopic cylinder.

[0011] Optionally, the transmission component further includes a second bevel gear transmission component, one end of which is connected to a square rod.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] like Figures 1 to 12 As shown, a 3D scanning and mapping verticality laser detection device includes: The scanning and mapping instrument 3, the tripod 4, and the extension mechanism 2 are provided. The tripod 4 is sleeved on the outside of the extension mechanism 2, and the scanning and mapping instrument 3 is located at the movable end of the extension mechanism 2. The extension mechanism 2 consists of a main telescopic cylinder 201, a first telescopic cylinder 202, and a second telescopic cylinder 203. The lower end of the first telescopic cylinder 202 is slidably installed inside the column telescopic cylinder, and the lower end of the second telescopic cylinder 203 is slidably installed inside the first telescopic cylinder 202. like Figures 1 to 12 As shown, through the design of the main telescopic cylinder 201, the first telescopic cylinder 202 and the second telescopic cylinder 203, all of which adopt a hollow design, the weight is reduced, making it convenient for staff to carry. Compared with the traditional method of lifting using a screw thread sleeve, it is much lighter.

[0032] Telescopic mechanism 1 is located outside the main telescopic cylinder 201, and the first telescopic cylinder 202 and the second telescopic cylinder 203 are both connected to the telescopic mechanism 1 for transmission. The first telescopic cylinder 202 and the second telescopic cylinder 203 are located close to or away from the main telescopic cylinder 201 through the telescopic mechanism 1. The telescopic mechanism 1 consists of a linkage component 101, a transmission switching component 103, and a transmission component 108. The linkage component 101 is located on the upper outer side of the main telescopic cylinder 201. The transmission switching component 103 is connected to the linkage component 101. The transmission component 108 is located on the upper outer side of the first telescopic cylinder 202. The second telescopic cylinder 203 is located near or away from the main telescopic cylinder 201 through the transmission component 108.

[0033] like Figures 1 to 12 As shown, through the design of the linkage component 101, the transmission switching component 103, and the transmission component 108, the second telescopic cylinder 203 and the first telescopic cylinder 202 can achieve automatic lifting and lowering. Furthermore, the linkage component 101, the transmission switching component 103, and the transmission component 108 as a whole adopt a gear meshing and toothed groove method to achieve lifting and lowering. At the same time, the toothed groove is opened on the outside of the first telescopic cylinder 202 and the second telescopic cylinder 203, thereby achieving the lifting and lowering function with small parts. Compared with the traditional structure that uses a screw thread sleeve that occupies a large area for lifting and lowering, it is lighter, with thin cylinder walls and internal cavities. The overall weight is significantly reduced compared with solid rods or lead screw nut pairs, and the portability is significantly improved. Furthermore, the lead screw must run through the entire inner cylinder and occupy the central axis, resulting in severe compression of the effective internal space.

[0034] Meanwhile, traditional screw threaded sleeves require axial layout and the motor also needs to be coaxially installed, resulting in a long rod shape, high center of gravity, and easy swaying. In contrast, this application adopts a ring layout, which achieves the advantages of a low center of gravity and no swaying.

[0035] Furthermore, the telescopic mechanism 1 also includes multiple sets of first drive gears 102 and dual-axis servo motors 106. The outer side of the first telescopic cylinder 202 is provided with tooth grooves that mesh with the first drive gears 102. The dual-axis servo motors 106 control the rotation of the first drive gears 102 through the linkage component 101. The upper outer side of the main telescopic cylinder 201 is provided with a mounting groove, and the dual-axis servo motors 106 are movably mounted inside the mounting groove. like Figures 1 to 12 As shown, the design of having a toothed groove on the outer side of the first telescopic cylinder 202 that meshes with the first drive gear 102 achieves a small gear module, with the toothed groove directly opened on the cylinder wall, resulting in fewer parts and lighter weight, which is lighter than the traditional method of using a solid lead screw. In the traditional method of using a screw, the screw must be matched with a long nut, which results in high friction and easy wear of the threaded pair, and the nut is large and heavy.

[0036] Secondly, the dual-axis servo motor 106 is located inside the mounting slot and will not protrude from the cylinder, making the overall shape more simplified.

[0037] like Figures 1 to 12 As shown, the multiple sets of first drive gears 102 are arranged in a ring at equal intervals and are located at the left, right and front and rear positions of the first telescopic cylinder 202, which can achieve more stable drive and thus prevent the first telescopic cylinder 202 from shaking during the lifting and lowering process.

[0038] Furthermore, the linkage component 101 includes multiple sets of first expansion shells 1012. Multiple sets of rotating grooves are formed around the upper part of the main telescopic cylinder 201. The first drive gear 102 is rotatably installed inside the rotating groove. The multiple sets of first expansion shells 1012 are interconnected, and each set of first expansion shells 1012 is rotatably installed with a first linkage rod 1011. One set of first linkage rods 1011 is connected to the dual-axis servo motor 106. The first linkage rod 1011 is fixedly connected to the first drive gear 102. The two sets of first linkage rods 1011 that are horizontally and vertically intersecting are provided with a first bevel gear transmission member 1013 at the same end. Thus, the two sets of first linkage rods 1011 that are horizontally and vertically intersecting are connected to each other through the first bevel gear transmission member 1013. For example, such as Figures 1 to 12 As shown, because the two sets of first linkage rods 1011 that are intersecting horizontally and vertically achieve a 90-degree steering transmission through the first bevel gear transmission component 1013, the dual-axis servo motor 106 can simultaneously drive multiple first linkage rods 1011 to rotate, thereby realizing the synchronous rotation of multiple sets of first drive gears 102, achieving stable lifting and lowering of the first telescopic cylinder 202.

[0039] Secondly, the first linkage rod 1011 and the first bevel gear transmission component 1013 of this application can be made of powder metallurgy small modules, which can further reduce the weight. In contrast, traditional screw thread sleeves require long couplings or bevel gearboxes to achieve steering, and the parts are large and heavy. Therefore, this application can be further lightweight.

[0040] like Figures 1 to 12 As shown, passed; Furthermore, one end of one set of first linkage rods 1011 is rotatably mounted with a mounting shell 105, and one end of the mounting shell 105 is provided with a sliding groove. The dual-axis servo motor 106 is slidably mounted inside the sliding groove, and one end of one output shaft of the dual-axis servo motor 106 is connected to the transmission switching component 103. One end of the other output shaft of the dual-axis servo motor 106 is keyed to a docking rod 107. One end of one set of first linkage rods 1011 is provided with a locking groove, and the docking rod 107 is slidably inserted into the locking groove. like Figures 1 to 12As shown, by sliding the docking rod 107 into the engaging groove, the dual-axis servo motor 106 can dock with the transmission switching component 103 and control the transmission component 108 to drive the second telescopic cylinder 203 to perform lifting and lowering operations without controlling the rotation of the first drive gear 102. Furthermore, the transmission switching component 103 includes a first connector 1035, a second connector 1036, and a first bevel gear 1032. The first connector 1035 and the second connector 1036 are fixedly arranged together. The second connector 1036 is keyed to one end of one output shaft of the dual-axis servo motor 106. A through hole is formed in the middle of one set of first drive gears 102, and one output shaft of the dual-axis servo motor 106 is located inside the through hole. The second connector 1036 is engaged with one set of first drive gears 102. The first connector 1035 and the first bevel gear 1032 are detachably arranged. The first bevel gear 1032 is rotatably installed inside the mounting slot and is connected to the transmission component 108. The lower end of the first telescopic cylinder 202 is elastically connected to a trigger plate 7. An extrusion strip 9 is fixedly installed on the outside of the trigger plate 7. The bottom of the extrusion strip 9 is inclined. A pressure plate 104 is fixedly installed on the upper surface of the first connector 1035. The upper end of the pressure plate 104 is inclined. An extrusion plate 1037 is fixedly installed on the lower outside of the first telescopic cylinder 202. An arc-shaped groove is opened on the upper surface of the extrusion plate 1037. The connection between the first connector 1035 and the second connector 1036 is conical, forming a conical column. The extrusion plate 1037 and the conical column are vertically corresponding. Specifically, a docking plate 1034 is fixedly installed on one side of the second bevel gear 1033, and a docking groove is provided on one side of the docking plate 1034. A docking protrusion is provided on the side of the first pair of connectors 1035 and the second pair of connectors 1036 that are far apart from each other. The first pair of connectors 1035 is engaged with the docking groove and connected to the docking plate 1034 through the docking protrusion, while the second pair of connectors 1036 is engaged with one of the first drive gears 102 through the docking protrusion. The second bevel gear 1033 is engaged with one side of the first pair of connectors 1035, and a positioning sleeve 1031 is rotatably connected to one side of the second bevel gear 1033. The first bevel gear 1032 is rotatably installed on the outside of the positioning sleeve 1031. The first bevel gear 1032 and the second bevel gear 1033 are meshed with each other, and the positioning sleeve 1031 is fixedly installed inside the mounting groove.

[0041] like Figures 1 to 12As shown, through the design of the trigger plate 7, the extrusion strip 9, the pressure plate 104, and the conical column, when the first telescopic cylinder 202 extends to its position, the extrusion plate 1037 extrudes the conical column, causing the conical column to drive the first connector 1035 to approach the docking plate 1034 to achieve connection. Meanwhile, the second connector 1036 will move away from one of the first drive gears 102, preventing the dual-axis servo motor 106 from driving multiple sets of first drive gears 102 to rotate. The dual-axis servo motor 106 can control the transmission component 108 through the first bevel gear 1032 and the second bevel gear 1033, causing the transmission component 108 to drive the second telescopic cylinder 203 to perform lifting and lowering operations. When the second telescopic cylinder 203 descends and fits against the upper surface of the trigger plate 7, and continues to descend, the trigger plate 7 will drive the extrusion strip 9 to extrude the pressure plate 104. At this time, it will control the second connector 1036 to dock with one of the first drive gears 102. Therefore, switching can be achieved as soon as the position is reached, without the need for an electronically controlled limit switch, thus simplifying the wiring. Therefore, it adopts a purely mechanical trigger, resulting in a low failure rate. Compared with traditional screw threaded sleeves, which require additional limit switches or encoders to determine the position, it increases weight and wiring. Furthermore, the transmission component 108 includes multiple sets of second drive gears 1084. Multiple sets of drive grooves are opened around the upper end of the first telescopic cylinder 202. The second drive gears 1084 are rotatably installed inside the drive grooves. The outer side of the second telescopic cylinder 203 is provided with gear grooves corresponding to the second drive gears 1084. Two adjacent sets of second drive gears 1084 are mutually driven. like Figures 1 to 12 As shown, the multiple sets of second drive gears 1084 mentioned above are arranged in a ring at equal intervals, and are located at the left, right and front and rear positions of the second telescopic cylinder 203, so as to achieve more stable drive and thus avoid the second telescopic cylinder 203 from shaking during the lifting and lowering process. Furthermore, the transmission component 108 also includes a second bevel gear transmission component 1086. One end of the second bevel gear transmission component 1086 is connected to a square rod 1081. A bearing plate 6 is fixedly installed on the upper outer side of the first telescopic cylinder 202. The square rod 1081 is rotatably installed on the bottom of the bearing plate 6. The first bevel gear 1032 is slidably sleeved on the outside of the square rod 1081. An clearance hole is opened on the outside of the positioning sleeve 1031. The square rod 1081 passes through the clearance hole. The second bevel gear transmission component 1086 is disposed on the upper surface of the bearing plate 6, and the other end of the second bevel gear transmission component 1086 is connected to a synchronization mechanism 1085. One set of second drive gears 1084 is connected to the synchronization mechanism 1085. like Figures 1 to 12As shown, through the design of the square rod 1081, the clearance hole and the first bevel gear 1032 slidingly sleeved on the outside of the square rod 1081, the square rod 1081 can ensure that the second bevel gear transmission component 1086 can always be controlled when the first bevel gear 1032 rotates, thereby realizing the rotation of multiple sets of second drive gears 1084. Specifically, the transmission component 108 mentioned above also includes multiple sets of second expansion shells 1082, and the layout of the multiple sets of second expansion shells 1082 is the same as that of the first expansion shell 1012. However, the second expansion shells 1082 are fixedly connected to the outside of the first telescopic cylinder 202, the multiple sets of second expansion shells 1082 are interconnected, and a second linkage rod 1083 is rotatably installed inside the second expansion shell 1082. The two sets of second linkage rods 1083, which are intersecting horizontally and vertically, are mutually transmitted through a third bevel gear transmission component 1087.

[0042] It should be noted that the first bevel gear transmission component 1013, the second bevel gear transmission component 1086, and the third bevel gear transmission component 1087 mentioned above all use two sets of bevel gears meshing for transmission. Using two sets of bevel gears meshing for transmission is already a mature existing transmission technology. Those skilled in the art should know how to install and use the first bevel gear transmission component 1013, the second bevel gear transmission component 1086, and the third bevel gear transmission component 1087. Therefore, this invention will not elaborate on this.

[0043] Specifically, the upper surface of the bearing plate 6 mentioned above is provided with a protective shell 5, the second bevel gear transmission component 1086 is disposed inside the protective shell 5, and the synchronization mechanism 1085 is rotatably installed at one end of the protective shell 5. It should be noted that the synchronization mechanism 1085 mentioned above uses a timing pulley and a timing belt, and one of the second drive gears 1084 has a timing groove on its outer side for fitting with the timing belt, so that the second drive gear 1084 can rotate synchronously with the timing pulley through the timing belt.

[0044] The above description of the embodiments is only for the purpose of helping to understand the method and core ideas of the present invention. It should be noted that those skilled in the art can make several improvements and modifications to the present invention without departing from the principles of the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
