Description

Technical Field

[0001] This invention relates to the field of architectural surveying technology, specifically to a high-rise building surveying system and method. Background Art

[0002] With the continuous improvement of my country's economic level and the rapid development of electronic technology, people's quality of life is getting better and better. The number of high-rise buildings is increasing dramatically and their height is getting higher and higher. Therefore, architectural surveying technology plays an increasingly important role. Architectural surveying technology has entered a new era, constantly creating new and beautiful environments for mankind and becoming an important pillar of social civilization.

[0003] Existing high-rise building engineering surveying equipment still has the following problems when conducting on-site surveying:

[0004] 1. Before conducting surveying, the surveying instrument needs to be moved to the location in the high-rise building where the surveying needs to be carried out. However, due to the long length of the support legs of the surveying instrument and the large space it occupies, it is inconvenient to move it.

[0005] 2. Traditional building surveying instruments are fixed by simply placing the support legs on the ground. Since the surveying work is carried out on high-rise buildings, the higher the altitude, the greater the impact of wind on the surveying instrument. The conventional fixing method is not very effective and is prone to causing the surveying instrument to tilt when surveying high-rise buildings, which affects the subsequent surveying results.

[0006] 3. Because traditional building surveying instruments do not have protective components on top, their detection efficiency will be reduced and they will be easily damaged when used in extreme weather conditions such as rain or strong sunlight. Summary of the Invention

[0042] 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.

[0043] Example 1:

[0044] Please refer to Figures 1-7. The present invention provides a technical solution: a high-rise building surveying system, including a fixing component 1, a surveying instrument body 3 is provided on the upper surface of the fixing component 1, a control panel 4 is provided on the surface of the surveying instrument body 3, a display screen 32 and control buttons 2 are provided on the surface of the control panel 4, three support rods 8 are provided below the fixing component 1, a first fixing block 18 is provided at the end of the support rod 8, two symmetrically arranged fixing rods 20 are fixedly connected to the upper surface of the fixing component 1, and a placement frame 5 is fixedly connected to the ends of the two fixing rods 20, and a telescopic cloth 26 is provided inside the placement frame 5;

[0045] The fastener 1 is provided with a shielding component for extending the telescopic cloth 26, and an auxiliary component for folding the support rod 8;

[0046] The surface of the support rod 8 is provided with support components to enhance the stability between the main body 3 of the surveying instrument and the ground.

[0047] More specifically, in this embodiment, by controlling the auxiliary components, the surveying can be completed.

[0048] The three support rods 8 below the main body 3 can be folded and retracted, and then the staff can move the main body 3 of the surveying instrument to the location in the high-rise building where it needs to be surveyed. Folding and retracting the support rods 8 before moving the main body 3 of the surveying instrument greatly reduces the space occupied by the support rods 8 during the movement, and provides convenience for the staff to move the main body 3 of the surveying instrument in the high-rise building.

[0049] Next, by controlling the auxiliary components, the three support rods 8 are stretched to an angle that is easy to fix with the building ground. Then, the first fixing block 18 under the support rods 8 can fix the main body of the surveying instrument 3 to the ground. Then, by controlling the support components on the support rods 8, the stability of the support rods 8 when fixed with the ground can be enhanced. This avoids the problem that the main body of the surveying instrument 3 is easily affected by strong winds when surveying high-rise buildings at high altitudes, causing the main body of the surveying instrument 3 to tilt during the surveying, thus affecting the surveying results.

[0050] While the support rod 8 is stretched to fix the main body 3 of the surveying instrument, the shielding component will also start working simultaneously. Under the action of the shielding component, the telescopic cloth 26 inside the placement frame 5 can be opened to shield the top of the main body 3 of the surveying instrument. This effectively avoids the problem of the control panel 4 being inconvenient to control and adjust when using the main body 3 of the surveying instrument in extreme weather such as rain or sun exposure, which reduces the detection efficiency of the main body 3. It also avoids the problem of the main body 3 of the surveying instrument being easily damaged in extreme weather due to the lack of a protective component on top of the main body 3.

[0051] Example 2, based on the above examples,

[0052] Furthermore, the auxiliary components, support components, and shielding components in Embodiment 1 are disclosed. The auxiliary components include a support plate 21 fixedly connected to the lower surface of the fixing member 1. A motor 22 is provided on the surface of the support plate 21. A rotating shaft 24 is fixedly connected to the output shaft of the motor 22. A gear 23 is fixedly connected to the surface of the rotating shaft 24. A connecting rod 7 is fixedly connected to the lower surface of the fixing member 1. A movable disk 6 is slidably connected to the surface of the connecting rod 7. A rack row 34 that meshes with the gear 23 is fixedly connected to the upper surface of the movable disk 6.

[0053] The auxiliary components also include hinge blocks 30 fixedly connected to the side of the movable disk 6. There are three sets of hinge blocks 30, two in a group, and each set of hinge blocks 30 is hinged to a support rod 8.

[0054] A fixing plate 10 is fixedly connected to the surface of the connecting rod 7, and a hinge is fixedly connected to the side of the fixing plate 10.

[0055] Block 2 31, two of which are set together, are arranged in three groups. The surface of the support rod 8 is fixedly connected to the second fixing block 29. The second fixing block 29 and the hinge block 2 31 are hinged together by a hinge plate 9.

[0056] The shielding component includes a second rotating shaft 19 that is rotatably connected to the fixed component 1. The telescopic cloth 26 includes a fixed end 263, a telescopic cloth body 262, and a stretching end 261. The telescopic cloth 26 is fixedly connected to the inner wall of the placement frame 5 through the fixed end 263. The second rotating shaft 19 extends into the interior of the placement frame 5 and is rotatably connected to it. A rotating plate 27 is fixedly connected to the end of the second rotating shaft 19 that extends into the placement frame 5. The rotating plate 27 is fixedly connected to the stretching end 261.

[0057] A bevel gear transmission mechanism 25 is provided between the second rotating shaft 19 and the first rotating shaft 24.

[0058] The support component includes a disc 14 fixedly connected to the surface of the support rod 8. A threaded sleeve 16 is rotatably connected to the surface of the disc 14, and the surface of the threaded sleeve 16 is provided with anti-slip texture 17.

[0059] It also includes a threaded rod 12, which is threadedly connected to a threaded sleeve 16, and a counterweight 15 is fixedly connected to the lower surface of the threaded rod 12.

[0060] There are three sets of threaded rods 12 and threaded sleeves 16, which correspond one to one. The three sets of threaded rods 12 and three threaded sleeves 16 are distributed in a circle on the disc 14. A belt pulley transmission mechanism 13 is provided between the three threaded sleeves 16. A triangular plate 11 is fixedly connected to the ends of the three threaded rods 12.

[0061] More specifically, in this embodiment, as shown in Figure 2, this state is when the angle between the three support rods 8 and the main body 3 of the surveying instrument is small. At this time, the three support rods 8 have not yet been spread out. At this time, the staff can hold the connecting rod 7 and move the main body 3 of the surveying instrument in the high-rise building. After the main body 3 of the surveying instrument is moved to the position where it needs to be surveyed, the motor 22 is turned on, which drives the rotating shaft 24 to rotate 180 degrees. The rotation of the rotating shaft 24 will drive the gear 23 to start rotating. The rotation of the gear 23 will drive the rack 34 meshing with it to move downward. The downward movement of the rack 34 will drive the movable disk 6 fixedly connected to it to move downward.

[0062] Due to the hinge between the support rod 8 and the movable disk 6, and under the action of the hinge plate 9, the downward movement of the movable disk 6 will cause the support rod 8, which is hinged to it, to extend outward away from the connecting rod 7. That is, the angle between the support rod 8 and the connecting rod 7 will increase, meaning the support rod 8 will then support...

[0063] The relatively mature existing technologies will not be discussed in detail here.

[0064] After the surveying of the high-rise building is completed, the reverse motor 22 drives the rotating shaft 24 to rotate 180 degrees in the opposite direction, which causes the rack 34 meshing with it to move upward and reset. The upward movement of the rack 34 will drive the moving disk 6 to move upward and reset. Under the hinge action between the moving disk 6 and the support rod 8, the upward movement of the moving disk 6 will cause the support rod 8 to retract towards the connecting rod 7, thereby retracting the three support rods 8 under the main body 3 of the surveying instrument.

[0065] Similarly, the reverse rotation of shaft 1 24 will also cause shaft 2 19 to rotate in the opposite direction, thereby causing the stretching end 261 of the telescopic fabric 26 to rotate in the opposite direction and retract the main body 262 of the telescopic fabric back into the placement frame.

[0066] Within 5 seconds, the entire device can be reset, meaning the three support rods below the main body 3 of the surveying instrument will now be in place.

[0067] 8 will occupy less space, at which point the staff can retrieve the main body 3 of the surveying instrument or move it to the next location in the high-rise building that needs to be surveyed, which provides convenience for the movement and storage of the main body 3 of the surveying instrument.

[0068] Example 3, based on the above examples,

[0069] Furthermore, in order to extend the service life of the main body 3 of the surveying instrument, a protective shell 28 is rotatably connected to the surface of the second rotating shaft 19, and the first rotating shaft 24 extends into the interior of the protective shell 28 and is rotatably connected to it.

[0070] More specifically, in this embodiment, since the protective shell 28 is rotatably connected to both the first rotating shaft 24 and the second rotating shaft 19, the protective shell 28 will not easily tilt or move. Under the action of the protective shell 28, the bevel gear transmission mechanism 25 can be protected, thereby extending the service life of the bevel gear transmission mechanism and also extending the service life of the surveying instrument body 3.

[0071] Working principle:

[0072] S1: When the surveying instrument moves, the reverse rotation of motor 22 will cause the moving disk 6 to move upward and the support rod 8 to retract towards the connecting rod 7, thereby retracting the three support rods 8 below the main body of the surveying instrument 3. At this time, the staff can move the main body of the surveying instrument 3 to the location in the high-rise building where it needs to be surveyed.

[0073] S2: The surveying instrument is fixed, and motor 22 is turned on to rotate in the forward direction, causing the rack and pinion 34 and the moving disk 6 to move in tandem.

[0074] Moving the support rod 8 downwards allows it to extend outwards away from the connecting rod 7, thus opening the support rod 8. At this point, the support rod 8 can be fixed to the ground by the first fixing block 18 below the support rod 8.

[0075] Rotate the threaded sleeve 16 with anti-slip texture 17 to drive the three threaded sleeves 16 to rotate synchronously, and cause the threaded rod 12 to drive the counterweight 15 to move downward until the counterweight 15 descends to the position of contact with the ground. Under the action of the counterweight 15, the stability of the support rod 8 when fixed to the ground can be enhanced, thereby completing the fixation of the main body 3 of the surveying instrument.

[0076] S3: Building surveying and inspection. By controlling the control button 2 on the control panel 4, the surveying work of the high-rise building can be started, and the surveying results will be displayed on the display screen 32.

[0077] S4: Surveying instrument recovery. After the surveying work of the high-rise building is completed, the reverse motor 22 drives the moving disk 6 to move downward, which causes the support rod 8 to retract towards the connecting rod 7, thereby retracting the three support rods 8 under the main body of the surveying instrument 3.

[0078] S5: At the same time, the reverse rotation of motor 22 will also drive the rotating shaft 19 to rotate in the opposite direction, thereby driving the stretching end 261 to rotate in the opposite direction and retracting the stretch fabric body 262 back into the placement frame 5. At this time, the reset of the entire device can be completed.

[0079] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
