Description

Technical Field

[0001] This utility model relates to the field of geological surveying and mapping technology, specifically to a total station for geological surveying and mapping. Background Technology

[0002] In the process of geological surveying, the total station is a commonly used surveying instrument. The total station is equipped with support legs at the bottom, which can provide stable support during the use of the total station and ensure the safety of the total station.

[0003] However, the existing total station still has the following drawbacks in use. When making coarse adjustments with the existing total station, the alignment of the positioning light point with the ground base point is adjusted by frequently raising and lowering the tripod. The inventor believes that this method is inconvenient.

[0004] Patent publication number CN217784685U discloses a total station for surveying. By adjusting the position of the ground laser through a translation slide, the total station can be calibrated more conveniently. After calibration, the slide is clamped by a braking mechanism to limit the translation of the slide, so that the total station can be used stably and avoid deviation, which would affect the surveying accuracy.

[0005] In the aforementioned patent, the total station solves the problems mentioned above. However, the total station still has the following problems: during the use of the total station, it needs to be supported by a tripod. When using the total station to measure on soft ground, stones need to be laid at the bottom of the total station. The process of laying stones needs to be done manually. At the same time, it is difficult to find stones on the ground when working outdoors. Furthermore, the tripod is easily stuck when it is directly installed on the ground, which brings inconvenience to the use of the total station.

[0006] To address the aforementioned issues, there is an urgent need for innovative design based on the existing total station structure. Utility Model Content

[0007] The purpose of this utility model is to provide a total station for geological surveying to solve the problems mentioned in the background art, which are that when using the total station to conduct measurements on soft soil, it is necessary to lay stones at the bottom of the total station, and the process of laying stones needs to be done manually. In addition, it is difficult to find stones on the ground when working outdoors, and the tripod is easily stuck when directly installed on the ground, which brings inconvenience to the use of the total station.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a total station for geological surveying, comprising a mounting base and a rotating base rotatably mounted on the upper end of the mounting base;

[0009] The upper end of the rotating base is fixedly installed with the instrument body and the protective plate, and the protective plate is located on both sides of the instrument body. The upper end of the rotating base is fixedly installed with a display, and the display is located at the front end of the instrument body.

[0010] A rotating rod is rotatably mounted on the lower end of the mounting base, and a lifting rod is slidably mounted inside the rotating rod, and a positioning rod is rotatably mounted on the lower end of the lifting rod.

[0011] The outer side of the lifting rod is provided with an adjustment structure for controlling the support state of the positioning rod; the inner side of the rotating rod is provided with a positioning structure for controlling the position of the lifting rod.

[0012] Preferably, the adjustment structure includes a support block and a sliding rod. The support block is fixedly installed on the outside of the positioning rod, and the sliding rod is rotatably installed on the outside of the positioning rod. Three sets of support blocks, sliding rods, and positioning rods are provided.

[0013] Preferably, a fixing plate is fixedly installed on the outer side of the lifting rod, and the fixing plate is located on the outer side of the sliding rod, and the upper end surface of the sliding rod is higher than the fixing plate.

[0014] Preferably, a positioning block is slidably installed inside the fixing plate, and a return spring is fixedly installed at the end of the positioning block away from the sliding rod, and a toggle rod is fixedly installed at the upper end of the positioning block.

[0015] Preferably, the sliding rod has positioning grooves equidistantly provided on the side near the positioning block, and the positioning grooves are engaged with the positioning block.

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

[0031] In a specific embodiment, such as Figures 1-2The basic operating procedure of the total station is shown in the figure.

[0032] Mounting base 1 and rotating base 2 rotatably mounted on the upper end of mounting base 1;

[0033] The upper end of the rotating base 2 is fixedly installed with the instrument body 3 and the protective plate 4, and the protective plate 4 is located on both sides of the instrument body 3. The upper end of the rotating base 2 is fixedly installed with the display 5, and the display 5 is located at the front end of the instrument body 3.

[0034] A rotating rod 6 is rotatably mounted on the lower end of the mounting base 1, and a lifting rod 7 is slidably mounted inside the rotating rod 6. A positioning rod 8 is rotatably mounted on the lower end of the lifting rod 7.

[0035] When using this geological surveying total station, it needs to be placed on the ground surface to be surveyed. Then, measurements can be taken using the total station. During the measurement process, the instrument body 3 and the display 5 need to be operational. When placing the total station, its height and angle need to be adjusted. During the height adjustment, the lifting rod 7 needs to slide downward inside the rotating rod 6, and the rotation angle of the rotating rod 6 on the mounting base 1 needs to be controlled to ensure that the total station can be stably supported. This completes the use of the total station.

[0036] In one specific embodiment, such as Figures 1-3 and Figures 6-7 The process of quickly adjusting the height of the total station is shown in the figure.

[0037] The rotating rod 6 has a positioning structure inside that controls the position of the lifting rod 7;

[0038] The adjustment structure includes a support block 9 and a sliding rod 10. The support block 9 is fixedly installed on the outside of the positioning rod 8, and the sliding rod 10 is rotatably installed on the outside of the positioning rod 8. There are three sets of support blocks 9, sliding rods 10 and positioning rods 8.

[0039] A fixing plate 11 is fixedly installed on the outside of the lifting rod 7, and the fixing plate 11 is located outside the sliding rod 10, and the upper end surface of the sliding rod 10 is higher than the fixing plate 11.

[0040] A positioning block 13 is slidably installed inside the fixed plate 11, and a return spring 14 is fixedly installed at the end of the positioning block 13 away from the sliding rod 10, and a toggle rod 15 is fixedly installed at the upper end of the positioning block 13.

[0041] The sliding rod 10 has equidistant positioning grooves 12 on one side near the positioning block 13, and the positioning grooves 12 are engaged with the positioning block 13.

[0042] When using this geological surveying total station, the height of the total station needs to be adjusted according to the terrain and the operator's requirements. During the height adjustment process;

[0043] The rotating rod 6 needs to be pulled directly to slide upward on the outside of the lifting rod 7. At this time, the seal 18 will separate from the air outlet 19, and the external air will enter the interior of the rotating rod 6 through the gap between the air outlet 19 and the seal 18. At this time, the internal air pressure at the upper end of the rotating rod 6 can be the same as the external air pressure. At this time, the support spring 20 is in a contracted state. During the movement of the lifting rod 7, the lifting rod 7 will drive the positioning rod 8 to move synchronously. When the positioning rod 8 moves to the required position, the lifting rod 7 can be stopped. Then the contracted support spring 20 will expand and push the seal 18 to reset, so that the seal 18 seals the air outlet 19, and the positioning rod 8 can be limited to this position.

[0044] During the process of reducing the brightness of the total station, the pressing block 21 needs to be pressed, which will cause the pressing block 21 to drive the sealing element 18 and the moving rod 17 to move. At this time, the sealing element 18 can be separated from the air outlet 19, and the lifting rod 7 can move upward inside the rotating rod 6, thereby reducing the height of the total station. This completes the height adjustment process of the total station, effectively improving the convenience of the total station height adjustment.

[0045] Based on the above embodiments, such as Figures 1-5 As shown, the application of this total station to different terrains is disclosed;

[0046] An adjustment structure for controlling the support state of the positioning rod 8 is provided on the outer side of the lifting rod 7;

[0047] The positioning structure includes a fixing block 16, which is fixedly installed inside the upper end of the rotating rod 6. A moving rod 17 is slidably installed inside the fixing block 16, and the end of the moving rod 17 away from the fixing block 16 is located outside the rotating rod 6. An air vent 19 is opened inside the rotating rod 6, and the air vent 19 is located outside the rotating rod 6.

[0048] A sealing element 18 is fixedly installed on the outer side of the moving rod 17, and the sealing element 18 is sealed to the air outlet 19. A pressing block 21 is fixedly installed on the end of the moving rod 17 away from the rotating rod 6. A support spring 20 is sleeved on the outer side of the moving rod 17, and the support spring 20 is located between the fixed block 16 and the sealing element 18.

[0049] When using this geological surveying total station, the support surface at the bottom of the total station needs to be adjusted according to the softness of the ground to ensure stable support of the total station.

[0050] When the total station is used on soft ground, the positioning rod 8 needs to be rotated to bring the support block 9 into contact with the ground. During this process, the actuating rod 15 needs to be moved. The movement of the actuating rod 15 will cause the positioning block 13 to move, and during this movement, the positioning block 13 will move away from the positioning groove 12. The positioning block 13 will also compress the return spring 14, causing it to contract. After the positioning block 13 separates from the positioning groove 12, the positioning rod 8 can then be rotated. The moving rod 10 will slide upward inside the fixed plate 11, and the support block 9 will rotate to the lower end of the positioning rod 8. At this time, the rotation of the positioning rod 8 can be stopped and the toggle rod 15 can be released. The contracted return spring 14 will expand and push the positioning block 13 to move. The positioning block 13 moves and engages with the positioning groove 12 again, thereby limiting the positioning rod 8 and the support block 9. By repeating the above steps, the positions of the three sets of positioning rods 8 and support blocks 9 can be adjusted, thereby ensuring the stable support of the total station and increasing the overall practicality.

[0051] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0052] Although embodiments of the present 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 present invention, the scope of which is defined by the appended claims and their equivalents.
