Description

Technical Field

[0001] This utility model relates to the field of land surveying technology, and in particular to a land engineering surveying device. Background Technology

[0002] In land surveying, the stability of the tripod directly determines the accuracy and reliability of the surveying instrument. Currently, common surveying devices generally employ a three-legged metal support structure, with pointed ends or small fixing pads at the ends, resulting in limited contact area with the ground. This traditional design can meet the requirements under hard, flat surface conditions. However, surveying environments are complex and varied, often involving farmland, tidal flats, sandy areas, and muddy conditions after rain—sites with soft soil and low bearing capacity. Under such harsh conditions, the ends of the legs are prone to sinking or lateral slippage, leading not only to repeated failures in instrument leveling and deviations in measurement data, but also potentially causing damage to expensive instruments due to sudden instability, severely restricting the efficiency and safety of surveying operations.

[0003] Existing technologies address such problems by adding fixed anti-settlement discs or detachable foot pads to the ends of the outriggers. However, some simple detachable foot pads have limited functionality, only slightly increasing the contact area and lacking an effective anti-displacement anchoring mechanism. They still cannot guarantee absolute stability on slopes or slippery surfaces, and their versatility and adaptability are insufficient. Therefore, we propose a land engineering surveying device.

Detailed Implementation

[0023] 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.

[0024] like Figure 1-5As shown, a land engineering surveying device includes a mounting platform 2. A total station 1 is movably mounted on the upper surface of the mounting platform 2. Three sets of support legs are rotatably connected to the periphery of the mounting platform 2. Each support leg includes a first support leg 3 rotatably connected to the upper end of the mounting platform 2. An adjustable second support leg 4 is slidably connected to the end of the first support leg 3. An auxiliary component is movably mounted at the end of the second support leg 4. The auxiliary component includes an extension plate 6. Extension plates 8 are rotatably connected to both sides of the extension plate 6. Vertical plates 7 are fixedly mounted on both sides of the upper surface of the extension plate 6. Adjustment grooves 11 are opened on the outer walls of the two vertical plates 7. Threaded rods 12 are rotatably mounted inside the adjustment grooves 11. Connecting seats 13 are threadedly connected to the outer walls of the threaded rods 12 and are slidably connected to the inner walls of the adjustment grooves 11. Two symmetrically arranged diagonal tie rods 9 are rotatably connected to the outer walls of the two extension plates 8 located on both sides of the extension plate 6, respectively, through the connecting seats 13.

[0025] The mounting platform 2 and the legs consisting of the first leg 3 and the second leg 4 are all existing technologies. The mounting platform 2 is equipped with multiple knobs for leveling the total station 1, and the connection between the first leg 3 and the second leg 4 can be equipped with a knob to adjust the length of the combined first leg 3 and the second leg 4. This is not described in detail here. When the three sets of legs are erected on soft and easily collapsible ground, the user can install the auxiliary components at the end of the second leg 4 according to the ground conditions by using the first limiting rod 10. Then, at the same time, the upper end of the threaded rod 12 is rotated to adjust the extension plates 8 on both sides of the extension plate 6 to be horizontal. After the two extension plates 8 are combined with the extension plate 6, the contact area between the end of the second leg 4 and the ground can be increased, avoiding the problem that the device is difficult to erect stably on soft and easily collapsible ground.

[0026] like Figure 4 As shown, a second positioning rod 17 is fixedly installed on the bottom surface of the extension plate 6. The second positioning rod 17 is tapered with a wider top and a narrower bottom. The second positioning rod 17 is inserted into the soil to prevent the three sets of support legs from shifting after being spread out, thereby further improving the stability of the device in use.

[0027] like Figure 5 As shown, an installation sleeve 5 is movably installed at the end of the second leg 4, and a first positioning rod 14 is fixedly installed on the bottom surface of the installation sleeve 5; the first positioning rod 14 has the same structure as the second positioning rod 17, and is mainly used to insert into the soil to further enhance the stability of the lower end of the second leg 4.

[0028] like Figure 5As shown, a second limiting rod 16 is provided at the upper end of the mounting sleeve 5. The cross section of the second limiting rod 16 is matched with the limiting hole 15, and the second limiting rod 16 passes through the interior of the limiting hole 15. The mounting sleeve 5 is installed at the end of the second support leg 4 through the second limiting rod 16, so that the user can easily remove the mounting sleeve 5 from the end of the second support leg 4.

[0029] like Figure 3 As shown, a limiting hole 15 is provided at the end of the second leg 4, and a first limiting rod 10 is provided between the lower ends of the two upright plates 7. The first limiting rod 10 passes through the lower ends of the two upright plates 7 and the interior of the limiting hole 15 in sequence, and the cross section of the first limiting rod 10 matches the limiting hole 15. The auxiliary component is installed at the end of the second leg 4 through the first limiting rod 10, and at the same time, it is convenient for the user to disassemble the auxiliary component and replace it with the mounting sleeve 5.

[0030] like Figure 3 and Figure 5 As shown, the first limiting rod 10 and the second limiting rod 16 have the same structure, both being cylindrical bodies with rectangular protrusions fixedly installed on their outer walls; the rectangular protrusions prevent the first limiting rod 10 and the second limiting rod 16 from rotating inside the limiting hole 15.

[0031] like Figure 3 and Figure 5 As shown, both ends of the second limiting rod 16 and the first limiting rod 10 are fixedly installed with threaded heads, and both ends of the first limiting rod 10 and the second limiting rod 16 are threadedly connected with nuts; the outer diameter of the nuts is larger than the cross-sectional outer diameter of the second limiting rod 16 and the first limiting rod 10. The nuts can limit the first limiting rod 10 and the second limiting rod 16 to prevent them from detaching from their installation positions.

[0032] The working principle of this utility model is as follows: During use, the user extends the three sets of first support legs 3 outwards and adjusts them to a stable state before installing the total station 1 on the upper surface of the mounting platform 2. In normal use, the mounting sleeve 5 is installed at the lower end of the second support leg 4 via the second limiting rod 16. Both ends of the second limiting rod 16 are threaded with nuts whose outer diameter is larger than the outer diameter of the cross-section of the second limiting rod 16. When the three sets of support legs are erected on ordinary soil, the first positioning rod 14 on the bottom surface of the mounting sleeve 5 inserts into the soil, enhancing the stability of the lower end of the second support leg 4. When the three sets of support legs are erected on soft, easily collapsing ground, the user can install auxiliary components at the end of the second support leg 4 via the first limiting rod 10, depending on the soil conditions. Then, simultaneously rotate the upper end of the threaded rod 12 to adjust the extension plates 8 on both sides of the extension plate 6 to be horizontal. After the two extension plates 8 are combined with the extension plate 6, the contact area between the end of the second leg 4 and the ground can be increased, avoiding the problem that the device is difficult to be stably erected on soft and easily collapsed ground. This makes the device suitable for land engineering surveying work in various environments. The bottom surface of the extension plate 6 is fixedly installed with a second positioning rod 17. The second positioning rod 17 is inserted into the soil to prevent the three sets of legs from shifting after being spread out, further improving the stability of the device in use. After the three sets of legs stably support the total station 1, the user can further level the total station 1 by using the knobs connecting the first leg 3 and the second leg 4 and the knobs on the mounting platform 2.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
