Description

Technical Field

[0001] This utility model relates to the field of engineering surveying equipment technology, specifically to a series support and protection device for a total station. Background Technology

[0002] A total station is a high-precision photoelectric measuring instrument that integrates electronic angle measurement, electronic distance measurement, data calculation, storage, and display. It uses laser beams to measure distances, angles, and elevations using infrared or electromagnetic waves, and is an indispensable core tool in modern engineering surveying such as construction, roads, bridges, tunnels, mines, and mapping. The installation, deployment, and fixation of a total station directly affect the accuracy and precision of its measurement results, and also significantly impact the efficiency of the measurement operation. Currently, total stations are generally mounted on a tripod using a base. After adjusting the height using the tripod, the total station is further leveled before the measurement operation begins.

[0003] However, tripods are not stable during use and are prone to tilting due to external environmental factors and human disturbance. If they overturn, they can damage equipment and even endanger personnel safety. Furthermore, the adjustable height of a tripod is limited. In some special geographical environments, if there is a significant elevation difference between the total station's deployment location and the measuring point, and the measuring point's horizontal level is higher than the tripod's maximum adjustable height, the total station will be unable to perform measurements because it is lower than the measuring point. In this case, surveyors need to temporarily elevate the tripod using a box or similar device to increase the total station's height. However, a tripod has three legs, and elevating it increases the difficulty of leveling the total station. Additionally, temporarily placing a box under the tripod makes the setup unstable. Alternatively, surveyors can find another relatively high location nearby to reposition the total station, but this affects surveying efficiency, especially when deploying the total station in areas such as bridges, where the entire bridge is at a uniform height, making it difficult to find a suitable high point for deployment.

[0004] Therefore, it is necessary to propose new measures to overcome the above-mentioned shortcomings. Summary of the Invention

[0005] The purpose of this invention is to provide a series support and protection device for total stations, in order to solve the problems of unstable support, impact on personnel safety, and limited height adjustment that exist in the current method of supporting total stations with tripods.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A series support and protection device for a total station is provided, the device comprising an instrument support plate, multiple fixed support units and a base; The fixed support unit includes multiple columns, and a crossbeam is connected between the top and bottom of adjacent columns. The crossbeam is provided with a vertically penetrating series hole. Multiple fixed support units are vertically combined and connected and fixed to each other by installing series bolts on the vertically corresponding series holes. The instrument support plate is fixed to the top of the top fixed bracket unit, and the center of the instrument support plate is provided with an instrument mounting hole for connecting to the total station base by bolts. The chassis is fixed to the bottom of the bottom fixed support unit.

[0007] Furthermore, the top of the column is provided with a vertical second column connection hole, and the instrument support plate is provided with a first column connection hole that is vertically corresponding to the second column connection hole. The instrument support plate and the top fixed bracket unit are connected and fixed to each other by mounting bolts in the second column connection hole and the first column connection hole.

[0008] Furthermore, the chassis is provided with a vertically penetrating screw hole, which corresponds vertically to the series hole of the bottom fixed support unit; The chassis and the bottom fixed support unit are connected and fixed to each other by installing grounding screws in the series hole and the screw hole.

[0009] Furthermore, the chassis is located on the ground, and the grounding screw is inserted downwards into the ground.

[0010] Furthermore, the device also includes a protective cover, which comprises a protective cover body and a protective cover body support rod; The protective cover is located above the instrument support plate and covers the top of the total station. The protective cover is fixed to the instrument support plate by vertical support rods arranged around its bottom edge.

[0011] Furthermore, the bottom of the protective cover is provided with a plurality of horizontally arranged radial rods, the inner ends of the plurality of radial rods intersecting at the bottom center of the protective cover, and the outer ends being fixed to the bottom edge of the protective cover.

[0012] Furthermore, the outer end of the radial rod is provided with a vertically penetrating protective cover mounting hole, and the top of the protective cover support rod has an external thread. The top of the protective cover support rod is inserted into the protective cover mounting hole and fixed by a nut.

[0013] Furthermore, the bottom of the protective cover support rod has external threads, and the instrument support plate is provided with a circumferential protective cover support rod connecting arc hole corresponding to the position of the protective cover support rod. The bottom of the protective cover support rod is inserted into the protective cover support rod connecting arc hole and fixed together by double bolts.

[0014] Furthermore, the column has multiple length specifications, forming fixed support units of different height specifications.

[0015] Furthermore, the instrument support plate is also provided with vertically penetrating drainage holes.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention provides a series support and protection device for total stations, replacing the tripod for support. With its base fixed to the ground, it effectively improves stability, preventing tilting or overturning caused by external environmental factors or human disturbance, thus protecting personnel safety and preventing equipment damage. Furthermore, it designs multiple fixed support units that can be vertically connected in series to support the total station for measurement operations. When the measuring point is higher than the total station and exceeds its measurement range, the total station's height can be quickly increased by adding more fixed support units vertically, eliminating the need to find a higher location to redeploy the total station. The overall structure of the frame is stable, reliable, and easy to operate. Attached Figure Description

The drawings illustrate preferred embodiments of this utility model. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0025] In the description of this utility model, it should be understood that the terms "center", "upper", "lower", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "setting," etc., should be interpreted broadly. For example, they can refer to a fixed connection or setting, a detachable connection or setting, or an integral connection or setting. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0027] Furthermore, in the description of this utility model, the terms "first," "second," etc., are used only for distinguishing descriptions and should not be construed as indicating or implying relative importance. Of course, such terms can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in a sequence other than those illustrated or described herein.

[0028] In a specific implementation, Figure 1 The direction from top to bottom is defined as "vertical". Figure 1The direction from left to right in the middle is defined as "horizontal".

[0029] To overcome the problem of limited tripod height adjustment, this utility model provides a series support and protection device for total station, used to fix and support the total station 5. It can be connected to the bottom of the total station base 6, replacing the traditional tripod. By changing the number of series structures, the height adjustment range of the support device can be expanded.

[0030] Specifically, the device includes, from top to bottom, a protective cover 1, an instrument support plate 2, multiple fixed support units 3, and a chassis 4.

[0031] The fixed support unit 3 includes multiple columns 31 arranged circumferentially and parallel to each other. Crossbeams 32 connect the top and bottom of adjacent columns 31, and can be connected and fixed by welding, bolting, or other methods, preferably by means that they can be separated and disassembled. The fixed support unit 3, composed of the columns 31 and crossbeams 32, forms a complete frame, generally columnar. Depending on the number of columns 31, the fixed support unit 3 has different horizontal cross-sectional shapes. For example, when three columns 31 are used, the horizontal cross-sectional shape of the fixed support unit 3 is triangular; when four columns 31 are used, the horizontal cross-sectional shape of the fixed support unit 3 is rectangular, and so on.

[0032] The fixed support unit 3 is the series structure of this device and is the core component that enables the device to change height. The crossbeam 32 of the fixed support unit 3 has a vertically penetrating series hole 33 located in the middle of the crossbeam 32. When multiple fixed support units 3 are vertically combined, the series holes 33 of adjacent crossbeams 32 are vertically aligned, and they are connected and fixed together after inserting series bolts 35. For example... Figure 1 In this embodiment, there are two fixed support units 3, one above the other, connected by series bolts 35. When the measuring point is higher than the measuring range of the total station 5, the series bolts 35 can be removed to separate the two fixed support units 3. Then, another fixed support unit 3 can be added between them, and the newly added fixed support unit 3 can be connected and fixed to the original two fixed support units 3 by the series bolts 35, thus changing the number of fixed support units 3 to three, thereby raising the total station 5.

[0033] Furthermore, the column 31 can have different lengths, thus forming fixed support units 3 of different heights. Depending on actual height adjustment requirements, fixed support units 3 of different heights can be selected to increase the overall height of the device.

[0034] The instrument support plate 2 is fixed to the top of the top fixing bracket unit 3. The instrument support plate 2 has an instrument mounting hole 21 in the center for bolt connection with the total station base 6. The total station 5 has a total station base 6 at the bottom. The total station base 6 is generally equipped with a screw in the center. The total station 5 can be fixed to the top of the instrument support plate 2 through the total station base 6.

[0035] In addition to connecting with the total station 5, the instrument support plate 2 is also connected upwards to the protective cover 1. The protective cover 1 includes a protective cover body 11 and protective cover support rods 12. The protective cover body 11 is located above the instrument support plate 2 and covers the top of the total station 5, providing protection for the total station 5. The protective cover body 11 is fixed to the instrument support plate 2 by vertically arranged protective cover support rods 12 around its bottom edge. Specifically, the bottom of the protective cover body 11 is provided with multiple horizontally arranged radial rods 13. The inner ends of the multiple radial rods 13 intersect at the bottom center of the protective cover body 11, and the outer ends are fixed to the bottom edge of the protective cover body 11. The outer ends of the radial rods 13 are provided with vertically penetrating protective cover mounting holes 14. The top of the protective cover support rods 12 has external threads, and the top of the protective cover support rods 12 is inserted into the protective cover mounting holes 14 and fixed with nuts. The bottom of the protective cover support rod 12 also has external threads. The instrument support plate 2 has a circumferentially arranged long arc hole 22 for connecting the protective cover support rod 12. The bottom of the protective cover support rod 12 is inserted into the long arc hole 22 and connected and fixed together by double bolts 15. The long arc hole 22 is a circumferentially arranged long hole, with a large range of fixing points. By fixing the bottom of the protective cover support rod 12 to different fixing points, the protective cover 1 can be rotated and adjusted, preventing the protective cover support rod 12 from obstructing the total station 5. When the protective cover support rod 12 obstructs the total station 5 during the change of observation angle, the protective cover support rod 12 can be moved in the long arc hole 22 to achieve rotational adjustment of the protective cover 11. In addition, the radial frame composed of multiple radial rods 13 also provides support and reinforcement for the protective cover 11.

[0036] Meanwhile, the instrument support plate 2 is also connected downwards to the fixed bracket unit 3 located at the top. Specifically, the top of the column 31 is provided with a vertical second column connection hole 34, and the instrument support plate 2 is provided with a first column connection hole 23 that is vertically corresponding to the second column connection hole 34. The instrument support plate 2 and the top fixed bracket unit 3 are connected and fixed to each other by mounting bolts 25 in the second column connection hole 34 and the first column connection hole 23.

[0037] In addition, to prevent water accumulation on the surface of the instrument support plate 2 and affect its use, the instrument support plate 2 is also provided with vertically penetrating drainage holes 24, which are evenly distributed at multiple points.

[0038] The chassis 4 is an important structure for fixing the bottom of the device. It is fixed to the bottom of the bottom fixing bracket unit 3 and located on the ground. The chassis 4 is provided with a vertical through screw hole 41, which corresponds vertically to the series hole 33 of the bottom fixing bracket unit 3. The chassis 4 and the bottom fixing bracket unit 3 are connected and fixed to each other by installing a grounding screw 42 in the series hole 33 and the screw hole 41. The grounding screw 42 is inserted downward into the ground.

[0039] like Figure 1-5 In this embodiment, the fixed support unit 3 has three columns 31 with a triangular horizontal cross-section. Correspondingly, three sets of series connection holes 33, first column connection holes 23, second column connection holes 34, and screw holes 41 are provided. In other embodiments, the number of columns 31 in the fixed support unit 3 can be increased to four, five, etc., and the number of other holes and bolts used for series connection can be changed accordingly. Additionally, in this embodiment, the protective cover 1 has three protective cover support rods 12, but the number can be adjusted to four according to actual needs. Correspondingly, the number of radial rods 13, protective cover mounting holes 14, and protective cover support rod connecting arc holes 22 can also be changed accordingly.

[0040] This invention incorporates multiple vertically connected fixed support units 3, which, when combined, support a total station 5 for measurement operations. When a measuring point is higher than the total station 5 and exceeds its measurement range, the total station's height can be quickly increased by adding more fixed support units 3 vertically, eliminating the need to find a higher location to redeploy the total station and simplifying operation. Simultaneously, because the bottom fixed support unit 3 is fixed to the ground, the stability of the support is effectively improved, preventing tilting or even overturning due to external environmental factors or human disturbance, thus protecting personnel safety and preventing equipment damage.

[0041] The above-described specific examples are for illustrative purposes only and are not intended to limit the scope of this invention. Those skilled in the art to which this invention pertains can make various simple deductions, modifications, or substitutions based on the concept of this invention.
