Description

Technical Field

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

[0002] Geological surveying positioning poles are markers used for positioning and measurement. They are usually made of metal, plastic, or wood and have a defined shape and size. Positioning poles typically have unique markings and numbers to help surveyors accurately record location information. Positioning poles play an important role in geological surveying for determining location, measuring distance, and direction. Surveyors can use surveying instruments, such as total stations or GPS receivers, in conjunction with positioning poles to obtain high-precision geographic coordinates and topographic data.

[0003] In existing technologies, positioning markers require a support device during installation. This device includes a grounding plate, forked pins, an adjustable support rod structure, and a mounting base. The grounding plate is fixed to the ground using the forked pins, and the mounting base is adjusted to a horizontal position using the adjustable support rod structure. The positioning marker is then fixedly installed on top of the mounting base, thus completing the vertical installation of the positioning marker. However, in actual use, the adjustable support rod structure only provides macroscopic horizontal adjustment to the mounting base and cannot guarantee that the mounting base is truly level. To achieve a level mounting base, the two adjustable support rod structures need to be repeatedly adjusted, which is time-consuming and cannot guarantee accuracy. This results in a certain deviation in the vertical installation of the positioning marker, affecting the accuracy of the surveying. Therefore, it is necessary to improve the positioning marker support device for geological surveying to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a benchmark support device for geological surveying to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a benchmark support device for geological surveying, comprising a fixed plate, a fixed shaft fixedly installed inside the fixed plate, a rotating cylinder rotatably installed outside the fixed shaft, a conical ball fixedly installed at the bottom of the rotating cylinder, and a positioning benchmark fixedly installed at the top of the rotating cylinder.

[0006] Preferably, the rotating drum is movably installed inside the fixed disk, and the angle between the positioning rod and the conical ball is 180°.

[0007] Preferably, the fixed disc has two threaded rods installed internally, and arc-shaped pressure plates are rotatably installed on the outside of each of the two threaded rods. Two limiting posts are fixedly installed on the outside of each of the two arc-shaped pressure plates, and friction plates are fixedly installed on the front and back of the rotating cylinder.

[0008] Preferably, the two friction plates correspond one-to-one with the two arc-shaped pressure plates, and the arc-shaped pressure plates abut against the friction plates.

[0009] Preferably, the limiting post is slidably installed inside the fixed plate, and the arc-shaped pressure plate is slidably installed inside the fixed plate.

[0010] Preferably, the fixed plate has two protrusions fixedly installed on its exterior, and an adjusting rod is rotatably installed inside each of the two protrusions. A fixed rod is slidably installed on the exterior of the adjusting rod, and a bolt is threaded inside the fixed rod. A ground plate is rotatably installed on the exterior of the bottom end of the fixed rod.

[0011] Preferably, the bolt is threaded inside the adjusting rod, and an anti-detachment block is fixedly installed at the bottom end of the adjusting rod, and the anti-detachment block is slidably installed inside the fixing rod.

[0012] Compared with the prior art, this utility model provides a benchmark support device for geological surveying, which has the following beneficial effects:

[0013] 1. This geological surveying marker support device uses an adjusting rod, a fixing rod, and bolts to adjust the height of two protrusions to be roughly the same, thereby adjusting the positioning marker and keeping it relatively vertical. Then, under the action of the conical ball, the positioning marker remains vertical, further ensuring the vertical installation of the positioning marker and making the surveying more accurate.

[0014] 2. Based on this, the present invention uses a threaded rod to drive the arc-shaped pressure plate to abut against the friction plate, so that the position of the rotating cylinder and the fixed shaft is fixed and cannot be rotated, thereby ensuring that the positioning rod is always in a vertical state and avoiding the problem of instability of the positioning rod caused by factors such as wind blowing.

[0015] 3. Based on this, the present invention completes the vertical fixation of the positioning pole by coarse adjustment and fine adjustment, which facilitates subsequent surveying. Attached Figure Description

[0022] 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.

[0023] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0024] Example 1:

[0025] Please see Figure 1-4 This utility model provides a technical solution: a benchmark support device for geological surveying, including a fixed plate 1, a fixed shaft 7 fixedly installed inside the fixed plate 1, a rotating cylinder 8 rotatably installed outside the fixed shaft 7, a conical ball 9 fixedly installed at the bottom of the rotating cylinder 8, and a positioning benchmark 14 fixedly installed at the top of the rotating cylinder 8.

[0026] Furthermore, the rotating cylinder 8 is movably installed inside the fixed plate 1, and the angle between the positioning rod 14 and the conical ball 9 is 180°, so that the positioning rod 14 is always vertical under the action of the conical ball 9.

[0027] Furthermore, two threaded rods 10 are installed inside the fixed disk 1, and arc-shaped pressure plates 11 are rotatably installed on the outside of the two threaded rods 10. Two limiting posts 12 are fixedly installed on the outside of the two arc-shaped pressure plates 11. Friction plates 13 are fixedly installed on the front and back of the rotating cylinder 8. The surface of the friction plate 13 near the arc-shaped pressure plate 11 is relatively rough and has a large friction force, which makes the position of the conical ball 9 more stable after the arc-shaped pressure plate 11 and the friction plate 13 come into contact.

[0028] Furthermore, the two friction plates 13 correspond one-to-one with the two arc-shaped pressure plates 11, and the arc-shaped pressure plates 11 abut against the friction plates 13, so that the rotating drum 8 and the fixed shaft 7 are fixed in position and cannot be rotated.

[0029] Furthermore, the limiting post 12 is slidably installed inside the fixed plate 1, and the arc-shaped pressure plate 11 is slidably installed inside the fixed plate 1. The arc-shaped pressure plate 11 abuts against the friction plate 13, so that the rotating cylinder 8 and the fixed shaft 7 are fixed in position and cannot be rotated, thereby making the positioning rod 14 initially in a vertical state and then fixed.

[0030] Example 2:

[0031] Please see Figure 1-2 Furthermore, in conjunction with Embodiment 1, it is further found that the fixed plate 1 has two protrusions 2 fixedly installed on its exterior, and an adjusting rod 3 is rotatably installed inside each of the two protrusions 2. A fixed rod 4 is slidably installed on the exterior of the adjusting rod 3, and a bolt 5 is threaded inside the fixed rod 4. A grounding plate 6 is rotatably installed on the bottom of the fixed rod 4 to facilitate fixing to the ground and ensure the stability of the device.

[0032] Furthermore, bolt 5 is threaded inside the adjusting rod 3, and an anti-detachment block is fixedly installed at the bottom of the adjusting rod 3. The anti-detachment block is slidably installed inside the fixed rod 4 to prevent excessive pulling from causing the adjusting rod 3 to separate from the fixed rod 4.

[0033] In actual operation, when this device is used, fork-shaped plates are pre-welded to the bottom of the two ground plates 6. The bottom of the fork-shaped plates is covered with fork-shaped nails, and the top is welded to the bottom of the ground plate 6. According to the moving distance, the fork-shaped nails at the bottom of the two ground plates 6 are inserted into the ground, so that the two ground plates 6 are fixed to the ground. When the ground is relatively flat, there is no need to change the position of the adjusting rod 3 inside the fixed rod 4. The adjusting rod 3 and the fixed rod 4 are fixed by bolts 5. When the ground is inclined, the bolts 5 inside the fixed rod 4 at the lower part of the ground can be removed, and then the adjusting rod 3 is pulled upward to move the protrusion 2 connected to it upward until the two protrusions 2 on the left and right are visibly at the same height. Then the bolts 5 are re-threaded into the adjusting rod 3 and the fixed rod 4 to fix the position of the adjusting rod 3 and the fixed rod 4, so that the height difference between the two protrusions 2 is not large, thus completing the pre-adjustment of the fixed plate 1 and avoiding a large height difference between the two protrusions 2, thereby adjusting the positioning rod 14 and keeping it in a vertical state.

[0034] Furthermore, due to the large weight of the conical ball 9, it remains perpendicular to the ground under the influence of gravity. This ensures that the positioning rod 14 remains vertical under the action of the conical ball 9, further guaranteeing the vertical installation of the positioning rod 14. This makes the surveying more accurate and avoids the problem that conventional positioning rods 14 are directly installed on the top of the mounting base, and the adjustment rod 3 and the fixing rod 4 alone cannot guarantee that it is completely vertical.

[0035] Furthermore, once the positioning rod 14 is vertical under the action of the conical ball 9, the threaded rod 10 is screwed inside the fixed plate 1, thereby driving the arc-shaped pressure plate 11 to approach the friction plate 13 until the arc-shaped pressure plate 11 abuts against the friction plate 13, so that the rotating cylinder 8 and the fixed shaft 7 are fixed in position and cannot be rotated, thus ensuring that the positioning rod 14 is always in a vertical state, avoiding the problem of instability of the positioning rod 14 caused by factors such as wind blowing.

[0036] Furthermore, the surface of the friction plate 13 near the arc-shaped pressure plate 11 is relatively rough, resulting in greater friction. Under the action of the two limiting posts 12, the arc-shaped pressure plate 11 moves back and forth, making the position of the conical ball 9 more stable after the arc-shaped pressure plate 11 and the friction plate 13 come into contact, thus ensuring that the positioning rod 14 remains stable after being fixed in position.

[0037] On the other hand, if the adjustable adjustment rod 3 and the fixed rod 4 are not provided, when the ground is uneven and the height difference between the two protrusions 1-2 is large, the conical ball 9 may abut against the edge of the movable groove of the fixed plate 1 and thus cannot move, so that the positioning rod 14 cannot be in a vertical state. Therefore, the adjustment of both aspects is indispensable. The two work together to complete the vertical fixation of the positioning rod 14, which is convenient for subsequent surveying.

[0038] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
