Description

Technical Field

[0001] This utility model relates to the field of mine surveying, and in particular to a total station for underground mine cross-section measurement. Background Technology

[0002] Mine surveying refers to the mapping work carried out during the construction of a mine, including planning and design, exploration and construction, and mine decommissioning. Total stations are frequently used in mine surveying. The tripod of a total station typically has a tapered support foot at the end that contacts the ground. When the total station is placed on the ground, the support foot contacts the ground and is thus fixed in place. However, because some mine surfaces consist mainly of soil and gravel, the contact area between the support foot and the ground is small. During the measurement process, under the weight of the total station itself, the support foot exerts pressure on the ground, causing it to gradually sink and resulting in a horizontal shift of the machine body, affecting the measurement results. Therefore, it is necessary to add a support structure to increase the contact area between the lower structure of the tripod and the ground, improving the stability of the device.

[0003] The prior art patent application with publication number CN221684043U describes a method that involves engaging the lower end of a clamping plate with a toothed plate, then pushing a limiting block towards the clamping plate to abut against it. A limiting bolt is then passed through a slotted hole and connected to the limiting block. Tightening the limiting bolt secures the limiting block, thereby fixing the lower end of the clamping plate. Through the setting of the limiting component, the lower end of the clamping plate is effectively fixed, making it less likely for the clamping plate to move relative to or detach from the toothed plate in the front-back direction, thus improving the stability of the device.

[0004] By rotating the support plate towards the central axis of the tripod, compared to rotating it in the opposite direction and resting it on the ground, a stable triangular structure is formed, further improving the stability of the device. At the same time, the length of the clamping plate can be further shortened, reducing the space occupied by the clamping plate and improving ease of use.

[0005] The limiting block fixes the lower end of the clamping plate in the front-to-back direction, while the baffle limits and fixes the sides of the clamping plate in the left-to-right direction. By setting the baffle, the probability of the clamping plate moving relative to the toothed plate or detaching from the toothed plate is further reduced, thereby improving the stability of the device.

[0006] However, when using total stations in mines, protective covers are installed on the control panel to protect the total station during operation. However, when the entire total station is used in an exposed manner, using only partial protective covers will leave most parts of the total station unprotected, which will cause damage in the event of an impact.

[0007] Therefore, it is necessary to provide a total station for underground cross-section measurement in mines to solve the above-mentioned technical problems. Utility Model Content

Figure 10 This is a cross-sectional view derived from x′, z′, and y′. A total station for underground mine cross-section measurement includes:

[0041] The total station body 1 and two protective components 2 are respectively arranged on the left and right sides of the total station body 1. Each protective component 2 includes a telescopic rod 21 and a protective cover 22. The telescopic rod 21 is connected to the side of the total station body 1, and the protective cover 22 is connected to one end of the telescopic rod 21.

[0042] Movable grooves 3 are provided on both the front and back sides of the surface of the protective cover 22.

[0043] A shielding component 5 is provided on the surface of the protective cover 22 and on the side opposite to the movable slot 3. The shielding component 5 includes a fixed rod 51, a movable frame 52 and a shielding plate 53. The fixed rod 51 is connected to the top of the protective cover 22, the movable frame 52 is disposed on the surface of the fixed rod 51, and the shielding plate 53 is connected to one side of the movable frame 52.

[0044] The use of the fixed rod 51 and the movable frame 52 facilitates the opening and closing of the cover 53 on the protective cover 22.

[0045] A fixing bolt 54 is provided between the fixed rod 51 and the movable frame 52.

[0046] A stop 55 is connected to the top of the fixing rod 51.

[0047] The bottom of the protective cover 22 is provided with a U-shaped through groove 4.

[0048] The use of the movable groove 3 facilitates the up-and-down movement of the lens on the total station body 1. The U-shaped through groove 4 facilitates the complete fitting of the protective cover 22 onto the surface of the total station body 1. The use of the external thread block 62, the connecting block 63, and the threaded sleeve 64 facilitates the fixing of the two protective covers 22 together.

[0049] A fixing component 6 is provided between the two protective covers 22. The fixing component 6 includes a fixing seat 61, an external threaded block 62, a connecting block 63, and a threaded sleeve 64. The fixing seat 61 is connected to the top of one of the protective covers 21, the external threaded block 62 is connected to one side of the fixing seat 61, the connecting block 63 is connected to the top of the other protective cover 22, and the threaded sleeve 64 is threaded to the surface of the external threaded block 62.

[0050] Please refer to sections 7 through 8. Figure 10 It is understood that points A and C are known control points in the preparation of office data, while point B is a hypothetical point artificially set on the cross-sectional line of the roadway (it needs to be line-of-sight with either point A or C). Using points A and C as backsight points, the total station is arbitrarily set up in a position line-of-sight with points A and B. Point B will be laid out after orienting the total station using the resection method.

[0051] Orient the instrument using the known backsight point method. Set the total station to the azimuth of the roadway cross-section (with the horizontal brake fixed). Then, use the total station's EDM (Electronic Direct Measurement) in prism-free (laser-based) fast tracking mode to measure the top and bottom details along the cross-section, directly obtaining the coordinates (x, y, z). When simultaneous measurement of the roadway longitudinal section is not required, the total station can be arbitrarily set at any point on the roadway cross-section, not necessarily a fixed point B. Figure 7 .

[0052] Similarly, when measuring the longitudinal profile of the roadway, the section B′ on the longitudinal profile line can be laid out, and then the measurement can be performed as in step 2. Figure 8 .

[0053] In surveying, both the cross and longitudinal profiles of the tunnel are crucial. When both cross and longitudinal profiles are required simultaneously, the method described in section 1 is used to lay out point B′′, where the cross and longitudinal profile lines intersect. The total station is then set up at B′′ for orientation. The horizontal or vertical circle of the total station is adjusted according to the orientation of the cross and longitudinal profile lines to begin the survey. Figure 9 .

[0054] Import the 3D coordinates (x, y, z) measured by the total station into an Excel spreadsheet, and then swap the y and z coordinates. The swapped coordinates will be in the format (x′, z′, y′), meaning the original z value will directly reflect the tunnel height in the cross-sectional view. The 3D coordinate data can then be imported into AutoCAD to directly generate a tunnel cross-sectional view.

[0055] The size of the balloon can be adjusted according to the actual situation. The fishing line is lightweight and its length can be adjusted flexibly. The measuring device is highly adaptable to the environment. Personnel can carry out measurements conveniently without entering the courtyard. The device is safe, economical and effective.

[0056] The working principle of the total station for underground cross-section measurement in mines provided by this utility model is as follows:

[0057] When using the total station body 1, to protect it, first pull the protective covers 22 on both sides of the total station body 1 and push them towards the middle under the action of the telescopic rod 21. After the protective covers 22 are fitted onto the surface of the total station body 1, the external threaded block 62 on one side of the fixed seat 61 is connected to the connecting block 63 and fixed by threaded connection between the threaded sleeve 64 and the external threaded block 62.

[0058] After the two protective covers 22 are fixed, the fixing bolt 54 between the fixing rod 21 and the movable frame 52 is removed. After the fixing bolt 54 is removed, the baffle plate 53 is pulled and moved upward under the action of the movable frame 52. When the baffle plate 53 moves upward, the movable slot 3 is opened. Then the fixing bolt 54 is passed through the movable frame 52 and connected to the fixing rod 51, and the total station body 1 can be used.

[0059] Compared with related technologies, the total station for underground cross-section measurement in mines provided by this utility model has the following beneficial effects:
