Description

Technical Field

[0002] Urban underground space encompasses underground buildings, transportation facilities, pipelines, and undeveloped areas, etc., which are the spaces below the ground surface. By surveying and mapping to obtain accurate information such as terrain, geological conditions, and the distribution of existing facilities, it can provide a basis for urban planning and optimize the use and layout of underground space.

[0003] Currently, most urban underground space surveying and mapping devices install total stations through ground brackets, and it is necessary to accurately level them to obtain the height difference and elevation data between the target point and the instrument. The traditional manual leveling method based on a spirit level requires multiple adjustments of the pitch angle and horizontal azimuth of the total station, and trial-and-error calibration is carried out by observing the position of the spirit level bubble. The operation process is lengthy. Due to high dependence on the experience of operators, in complex environments such as insufficient lighting and limited working space in underground spaces, it is not only difficult to achieve rapid and efficient adjustment, the time-consuming for single leveling is relatively long, but also the control accuracy of manual operation for fine angle adjustment is limited, which is likely to cause instrument leveling errors, thereby affecting the accuracy and reliability of surveying and mapping data.

Detailed implementation manners

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] Please refer to Figures 1 to 11 As shown, the present invention provides an embodiment:

[0033] An urban underground space surveying and mapping device includes a total station 1. The bottom of the total station 1 is fixedly connected with a base 2. The bottom of the base 2 is provided with a leveling component 3 and a support component 4. The leveling component 3 includes a fixed seat 31, a mounting rod 32, a connecting sleeve one 33, a connecting sleeve two 34, a mounting seat 35 and a clamping mechanism 36. The top of the mounting rod 32 is fixedly connected with the base 2. The connecting sleeve one 33 and the connecting sleeve two 34 are symmetrically threadedly installed inside the mounting seat 35. The ends of the connecting sleeve one 33 and the connecting sleeve two 34 away from each other are rotatably connected with the fixed seat 31. The outer side of the mounting rod 32 is symmetrically fixedly connected with mounting shafts 391. The inside of the mounting seat 35 is symmetrically fixedly connected with fixed sleeves 392. The mounting shafts 391 are all rotatably connected inside the fixed sleeves 392. The bottom of the mounting rod 32 is fixedly connected with a counterweight 37;

[0034] The clamping mechanism 36 includes a movable rod 361 and a clamping sleeve 362. The clamping sleeve 362 is slidably connected to the outer sides of the second connecting sleeve 34 and the mounting base 35. The movable rod 361 is slidably connected to the inside of the fixed base 31. Symmetrically fixed to the inside of the clamping sleeve 362 are clamping blocks 363. Through holes adapted to the clamping blocks 363 are formed in the outer side of the fixed sleeve 392. Fixed to the outer side of the movable rod 361 is a fixed disk 364. Slidably connected to the inside of the second connecting sleeve 34 are a movable block 365 and a movable disk 366. A first spring 368 is fixedly connected between the fixed disk 364 and the movable block 365. The movable block 365 is slidably connected to the inside of the movable disk 366. Symmetrically fixedly connected between the movable disk 366 and the clamping sleeve 362 are connecting blocks 367;

[0035] Rotatably connected to the inside of the fixed base 31 is a threaded sleeve 38. The movable rod 361 is threadedly connected to the threaded sleeve 38. The movable rod 361 passes through the movable block 365 and the first spring 368.

[0036] In the actual application of the embodiment of the present invention, as Figures 2 to 5 shown, when the total station 1 needs to be leveled and installed, relying on the fixed connection relationship between the top of the mounting rod 32 and the base 2, and using the gravitational force generated by the counterweight 37 at the bottom of the mounting rod 32, the mounting rod 32 is urged to rotate around the rotation connection point of the mounting shaft 391 and the fixed sleeve 392 in the mounting base 35. At the same time, the first connecting sleeve 33, the second connecting sleeve 34 and the mounting base 35 rotate in coordination within the fixed base 31 to achieve the automatic vertical positioning of the total station 1;

[0037] As Figures 3 to 7 shown, after the preliminary leveling is completed, by rotating the threaded sleeve 38 within the fixed base 31, due to the threaded connection relationship between the movable rod 361 and the threaded sleeve 38, the movable rod 361 is driven to move axially. When the movable rod 361 moves, it drives the fixed disk 364 to compress the first spring 368, and then pushes the movable block 365 to slide within the movable disk 366. The movable disk 366 drives the clamping sleeve 362 to slide along the outer sides of the second connecting sleeve 34 and the mounting base 35 through the connecting blocks 367. During the sliding process of the clamping sleeve 362, the clamping blocks 363 inside it are inserted into the adapted through holes on the outer side of the fixed sleeve 392. At the same time, the movable block 365 is in close contact with the movable disk 366, realizing the rotational restraint of the mounting rod 32 and completing the precise fixation of the horizontal orientation of the total station 1, effectively improving the accuracy and reliability of the underground space surveying and mapping data.

[0038] As Figure 5 and Figure 6 shown, through grooves are symmetrically formed on the outer side of the second connecting sleeve 34. The connecting blocks 367 are all slidably mounted within the through grooves.

[0039] In the actual application of the embodiment of the present invention, the sliding guiding and limiting effects of the connecting blocks 367 within the through grooves ensure the stability of the movement of the clamping sleeve 362.

[0040] As shown Figure 2 in the figure, the support assembly 4 includes a support base 41, a support rod 43 and a limit disc 44. The support rod 43 is rotatably connected to the support base 41 through a connecting mechanism 42. The support base 41 is fixedly connected to the bottom of the fixed base 31. An insertion mechanism 45 and a pushing mechanism 46 are arranged inside the limit disc 44.

[0041] In the actual application of the embodiment of the present invention, when it is necessary to support and fix the total station 1, the support rod 43 can be rotated through the connecting mechanism 42 so that it unfolds around the connection point with the support base 41. Since the support base 41 is fixedly connected to the bottom of the fixed base 31, the unfolded support rod 43 and the limit disc 44 form a stable support structure. To further enhance the fixing effect, the pushing mechanism 46 is operated, and its transmission effect is used to drive the insertion mechanism 45 to act. The insertion mechanism 45 is inserted into the ground to realize the rigid connection between the device and the ground, so as to effectively resist external force interference during the underground space surveying and mapping process and ensure the stability of the total station 1 and the reliability of the surveying and mapping data.

[0042] As shown Figure 2 and Figure 8 in the figure, the connecting mechanism 42 includes a mounting sleeve 421, a limit sleeve 422 and a limit shaft 423. The mounting sleeve 421 is fixedly connected to the inside of the support base 41. The limit shaft 423 is fixedly connected to the inside of the mounting sleeve 421. The limit sleeve 422 is fixedly connected to the top of the support rod 43. Two limit blocks 424 are fixedly connected to the outside of the limit shaft 423. The limit shaft 423 and the limit blocks 424 are both rotatably connected to the inside of the limit sleeve 422.

[0043] In the actual application of the embodiment of the present invention, when it is necessary to adjust the support state of the support assembly 4, the rotation and unfolding and storage of the support rod 43 are realized by using the structural characteristics of the connecting mechanism 42. When an operator applies force to the support rod 43, the limit sleeve 422 will rotate around the combined structure of the limit shaft 423 and the limit blocks 424, so that the support rod 43 makes an angle adjustment with the mounting sleeve 421 as the fulcrum. When the limit blocks 424 rotate in the limit sleeve 422, it not only ensures the smoothness of the rotation, but also restricts the displacement of the support rod 43 in an unexpected direction through its structure, realizing the stable unfolding or folding of the support rod 43 and building a stable support foundation for the total station 1.

[0044] As shown Figure 2 , Figure 9 , Figure 10 and Figure 11As shown, the insertion mechanism 45 includes an insertion seat 451 and a movable seat 452, the insertion seat 451 is slidably installed inside the movable seat 452, the movable seat 452 is slidably installed inside the limiting plate 44, the insertion seat 451 is rotatably connected to the bottom of the support rod 43, the interior of the insertion seat 451 is slidably connected with a movable sleeve 453, a spring 2 454 is fixedly connected between the movable sleeve 453 and the insertion seat 451, the bottom of the movable sleeve 453 is fixedly connected with an insertion rod 456 that passes through the insertion seat 451, the interior of the movable seat 452 is slidably connected with a push block 455, and the push block 455 is slidably installed inside the movable sleeve 453;

[0045] The pushing mechanism 46 includes a slider 461 slidably installed inside the limit plate 44, a connecting rod 462 is fixedly connected to the bottom of the slider 461, a push rod 463 is symmetrically fixedly connected to the outer side of the connecting rod 462, the connecting rod 462 is slidably connected to the push block 455 through the push rod 463, and a spring 464 is fixedly connected between the slider 461 and the limit plate 44.

[0046] In actual application of the embodiment of the present invention, when it is necessary to fix the surveying and mapping device to the ground, the operator applies external force to the slider 461 to overcome the elastic force of the spring three 464 and slide inside the limit plate 44. When the slider 461 moves downward, it drives the connecting rod 462 to move synchronously, and then pushes the push block 455 to slide in the movable seat 452 through the push rods 463 on both sides. After the push block 455 is compressed, the movable sleeve 453 drives the insertion rod 456 to penetrate the insertion seat 451 through the movable sleeve 453 under the elastic action of the spring two 454, and is vertically inserted into the ground to ensure that each support point is evenly stressed and enhance the stability of the device. When the surveying and mapping operation is completed and the device needs to be disassembled, the support rod 43 is pressed to reset so that the support rod 43 pushes the movable sleeve 453 through the push block 455, so that the insertion rod 456 is separated from the ground, which is convenient for moving and redeploying the device.
