Description

Technical Field

[0001] This utility model relates to the field of tripod technology, and in particular to a latitude and longitude measuring device for building safety inspection. Background Technology

[0002] In the field of building structural safety assessment, latitude and longitude measuring equipment plays a crucial role, its main function being to accurately acquire the geographical coordinate data of buildings. Currently, latitude and longitude measuring equipment in this field typically consists of a tripod and a rotating platform, with the total station mounted above the rotating platform. Utilizing the flexible rotating connection between the rotating platform and the tripod, the equipment can easily achieve precise adjustments in both vertical and horizontal directions.

[0003] A tripod typically consists of a support rod, multiple legs, and a positioning plate. The upper end of the support rod is rotatably connected to the legs, while its side end is slidably connected to the positioning plate. The side end of the positioning plate is in turn rotatably connected to the corresponding leg via a driven rod. In practice, the extension angle of the legs is adjusted by sliding the positioning plate up and down to meet different support requirements. Existing tripod technology utilizes the mutual constraints and frictional resistance between the legs to ensure that the positioning plate maintains a specific height when no external force is applied. This allows for precise control of the leg angles through a stable triangular relationship between the driven rod, support rod, and legs.

[0004] However, existing technology has significant limitations. Because its outrigger adjustment mechanism involves simultaneous adjustment of all three outriggers, the equipment is easily affected by environmental factors during installation and use. For example, in situations with uneven ground, slopes, or obstacles, adjustments to the site environment are necessary to achieve level calibration of the total station, such as clearing obstacles and leveling the ground. These additional adjustments not only increase labor intensity but also complicate the operating procedures, thus affecting work efficiency. Furthermore, in complex construction environments, adjustments to the site environment may face numerous limitations or even be impossible, further hindering the normal operation of latitude and longitude measuring equipment and reducing measurement accuracy.

[0005] In view of this, this study proposes a new type of latitude and longitude measuring device for building safety inspection. This device can independently adjust the horizontal and longitudinal projection lengths of a single location to better adapt to the changing site environment. Utility Model Content

[0006] To address the shortcomings of existing technologies, this invention proposes a theodolite measuring device for building safety inspection. This device enhances adaptability to the on-site environment by adjusting the angle of a single leg, solving the problem of fixed leg angles in existing technologies, which impose significant limitations on on-site conditions.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A theodolite measuring device for building safety inspection includes a tripod with a rotating platform slidably connected to its upper side. The tripod also includes a support rod with multiple legs rotatably connected to its upper end. A positioning plate is slidably connected to the side end of the support rod, and the side end of the positioning plate is rotatably connected to a corresponding support via a driven rod. Each leg includes a sleeve and a mating ring. The sleeve is inserted into the inner cavity of the mating ring, which is rotatably connected to the driven rod. The side end of the mating ring has a threaded hole and a through hole, with each threaded hole and the corresponding through hole coaxially arranged. The central axis of each threaded hole is perpendicular to the side end face of the corresponding sleeve. A through groove I is formed on the sleeve along the central axis of the corresponding threaded hole. A screw is inserted into the through groove I, with the middle end of each screw inserted into the corresponding through hole and the tail end screwed into the corresponding threaded hole. Simultaneously, the two axial ends of each screw apply opposing clamping forces to the corresponding side end of the sleeve.

[0009] Preferably, an inner rod is inserted inside the sleeve, and a through groove II is formed on the inner rod along the central axis of the corresponding internal thread hole. Each screw is simultaneously inserted into the corresponding through groove I and through groove II. A limiting member is fixedly connected to the side end of each screw. The limiting member is located inside the sleeve, and the side end of each inner rod abuts against the inner cavity of the sleeve and the limiting member, respectively.

[0010] Preferably, each inner rod is fixedly connected to a support leg at its lower end, and the projection of the support leg on the vertical plane is a conical structure.

[0011] Preferably, each screw has a rotating component fixedly connected to the end away from the corresponding internal threaded hole, and each screw has a contact pad of elastic material slidably connected to its side end. The contact pad is located on the side of the sleeve away from the corresponding internal threaded hole, and the contact pad abuts against the side end of the sleeve. At the same time, the rotating component applies an axial clamping force toward the sleeve to the contact pad.

[0012] Preferably, each screw is fitted with a transmission tube on its outer side, and the two axial ends of the transmission tube abut against the corresponding rotating part and the contact pad, respectively. Furthermore, the transmission tube is inserted into the corresponding through hole.

[0013] Preferably, the projection of the contact pad on the horizontal plane is a polygonal structure, and the sleeve has multiple limiting grooves on the side away from the support rod for the contact pad, with the multiple limiting grooves arranged equidistantly from top to bottom.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] Each outrigger in this invention consists of a sleeve and a mating ring. The sleeve is inserted into the inner cavity of the mating ring, which can move axially linearly relative to the sleeve. The mating ring is also rotatably connected to the driven rod. This design breaks the stable triangular relationship between the driven rod, support rod, and outrigger, enabling the adjustment of the angle of a single outrigger. During actual on-site installation, this device can adjust the angle of a single outrigger according to the actual terrain, allowing for better ground contact without requiring large-scale adjustments to the site environment, thus greatly improving the device's adaptability to different environments.

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] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "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.

[0025] like Figure 1 As shown, a theodolite measuring device for building safety inspection has a structure consistent with existing technology, mainly consisting of a tripod 1 and a rotating platform 2. In practical applications, the total-station theodolite is installed on the upper part of the rotating platform 2. Although the measuring instrument is not shown in detail in the figure, a cylindrical structure connected to it is visible above the rotating platform 2. By restricting the rotation between the rotating platform 2 and the tripod 1, this device achieves vertical height adjustment and horizontal rotation adjustment functions.

[0026] In detail, the tripod 1 includes a support rod 11, multiple legs 14, and a positioning plate 12. The upper end of the support rod 11 is rotatably connected to the legs 14, and the side end is slidably connected to the positioning plate 12. The side end of the positioning plate 12 is rotatably connected to the legs 14 via a driven rod 13. By sliding the positioning plate 12 up and down, the unfolding angle of the legs 14 can be adjusted to meet the needs of different support conditions.

[0027] Please see Figure 1 and Figure 2 The difference between the device of the present invention and the prior art is that the support leg structure is composed of a sleeve 141 and a mating ring 143. The sleeve 141 is embedded inside the mating ring 143, so that the mating ring 143 can slide axially linearly inside the sleeve 141.

[0028] It should be noted that existing technology devices, through the mutual constraint of multiple support legs and the effect of frictional resistance, can maintain the positioning plate 12 of the tripod at a specific height without external force. In this case, the angle of the support leg can be controlled through the stable triangular structure between the driven rod 13, the support rod 11, and the support leg. However, in this application, by changing the connection method between the mating ring 143 and the support leg, and restricting the rotational connection between the mating ring 143 and the driven rod 13, the stable triangular relationship between the driven rod 13, the support rod 11, and the support leg is disrupted by a sliding connection, thereby achieving adjustment of the angle of a single support leg. As the angle of the support leg changes, its projected length in the horizontal and vertical directions also changes accordingly. This facilitates the installation process of this application on actual ground, enabling rapid leveling of the total station theodolite.

[0029] It must be pointed out that in actual operation, when adjusting the relative position between the mating ring 143 and the corresponding support leg 14, causing a change in the position of one support leg 14 relative to the other two support legs 14, it is necessary to ensure that the relative position between the mating ring 143 and that support leg 14 remains unchanged. This measure is crucial for ensuring the stability of the total station theodolite during use.

[0030] See Figure 3 , Figure 5 , Figure 6 The mating ring 143 of this device has an internal threaded hole and a through hole on its side end, and each internal threaded hole and the corresponding through hole are coaxially arranged. The central axis of each internal threaded hole is perpendicular to the side end face of the corresponding sleeve 141.

[0031] In addition, this device has a through groove I 142 on the sleeve 141 along the central axis of the internal threaded hole, and a screw 144 is embedded in the through groove I 142. The middle end of the limiting screw 144 is embedded in the through hole, and the tail end is threaded to the internal threaded hole. After rotation, both ends apply a reverse clamping force to the side end of the sleeve 141, and fix the sleeve 141 and the mating ring 143 by friction.

[0032] Correspondingly, when the screw 144 is rotated in the opposite direction, the clamping force applied to the side of the sleeve 141 by both ends of the screw 144 is eliminated, which reduces the friction between the mating ring 143 and the sleeve 141, and realizes the relative movement between the mating ring 143 and the sleeve 141.

[0033] See Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 To ensure that the projected length of the outrigger 14 is adjustable, the sleeve 141 is fitted with a sliding inner rod 146. In actual operation, the total length of the outrigger 14 is changed by sliding the inner rod 146, while keeping the opening angle of the outrigger 14 constant, thereby adjusting the projected length of the outrigger 14 in the horizontal and vertical directions.

[0034] To ensure the stability of the total station theodolite, the relative lengths of the inner rod 146 and the sleeve 141 need to be controlled. Therefore, this device has a through groove II 145 on the inner rod 146 along the central axis of the internal threaded hole, while limiting each screw 144 to be simultaneously embedded in the corresponding through groove I 142 and through groove II 145.

[0035] Furthermore, a limiting member 1411 is fixedly connected to the side end of each screw 144, and the limiting member 1411 is located inside the sleeve 141. At this time, by rotating the screw 144, the position of the screw 144 (limiting member 1411) is adjusted using the internal threaded hole, so that the side end of the inner rod 146 contacts the inner cavity of the sleeve 141 and the limiting member 1411 respectively. In this way, the length of the support leg 14 can be adjusted and fixed when the screw 144 rotates.

[0036] Further, see Figure 2 , Figure 4 Each inner rod 146 is fixedly connected to a support leg 147 at its lower end. The projection of the support leg 147 in the vertical direction is a conical structure. This conical structure of the support leg 147 allows it to be inserted deeper into the ground, increasing the friction and stability between the support leg 14 and the ground, ensuring that the theodolite remains stable during use and avoiding shaking or displacement.

[0037] Please see Figure 3 , Figure 5 , Figure 6 To ensure smooth rotation of the screw 144, a rotating component is fixedly connected to the end of each screw 144 away from the corresponding internal thread hole. The rotating component facilitates operation by the operator.

[0038] In addition, anti-slip textures are added to the side of the rotating parts, which effectively improves the operator's control over the parts.

[0039] Therefore, to ensure that during the rotation of the screw 144, both ends of the screw 144 can apply a clamping force in opposite directions to the corresponding sleeve 141, a contact pad 149 is slidably connected to the side end of each screw 144. The contact pad 149 is located on the side of the sleeve 141 away from the corresponding internal thread hole, and the contact pad 149 is in close contact with the side end of the sleeve 141. At this time, it is only necessary to ensure that during the axial movement of the transmission component, it can apply an axial clamping force towards the sleeve 141 to the contact pad 149, thus ensuring that during the rotation of the screw 144, both ends of the screw 144 can apply a clamping force in opposite directions to the corresponding sleeve 141.

[0040] Further, please refer to Figure 2 , Figure 4 On the side of the support leg away from the positioning rod, this device is designed with multiple evenly distributed limiting grooves 1410 for the contact pad 149. These limiting grooves 1410 can effectively fix the height position of the contact pad 149, ensure the stability of the total station theodolite during use, and avoid shaking caused by single frictional resistance.

[0041] In addition, the projection of the contact pad 149 on the horizontal plane is designed as a polygonal structure. This design allows it to fit tightly with the limiting groove 1410, effectively limiting the rotation of the contact pad 149 and the screw 144, preventing the screw 144 from loosening, and thus improving the stability and reliability of the entire support leg 14 structure.

[0042] It is worth noting that the contact pad 149 is made of an elastic material, such as rubber, in practical applications. When the rotating component rotates and changes the contact position between the screw 144 and the internal threaded hole, the contact pad 149 deforms due to compression, thereby enhancing the clamping effect on the sleeve 141 and further improving the stability of the support leg 14 structure. In addition, this ensures that the limiting member 1411 can apply sufficient clamping force to the inner rod 146, avoiding travel conflict between the contact pad 149 and the limiting member 1411.

[0043] Specifically, in order to ensure that the rotating component can apply an axial clamping force toward the sleeve 141 to the contact pad 149 during the axial movement of the rotating component, the device is provided with a transmission tube 148 on the outside of each screw 144, and the two ends of the transmission tube 148 are in close contact with the corresponding rotating component and the contact pad 149 respectively.

[0044] It should be noted that you should refer to [link / reference]. Figure 5 , Figure 6 This device restricts the insertion of the transmission tube 148 into the through hole, meaning that the inner diameter of the transmission tube 148 is larger than the diameter of the screw 144. This not only prevents rotating parts from entering the through hole and affecting operation, but also makes the actual assembly process more convenient.

[0045] In practical applications, this utility model is as follows:

[0046] Preliminary leveling stage

[0047] The assembled theodolite measuring device is transported to the testing site and securely placed. The positioning plate 12 is manually slidable, and the outriggers 14 are driven by the driven rod 13 to adjust their opening angle to achieve the initial leveling state of the device.

[0048] Deep leveling stage

[0049] First, rotating the rotating component 1412 releases the clamping force applied by the elastic pad to the sleeve 141 and the clamping force applied by the limiting component 1411 to the inner rod 146. After the clamping force is released, the sleeve 141 and the inner rod 146 can slide freely, facilitating precise adjustment of the length of the support leg 14.

[0050] Based on this, the levelness of the device is continuously and meticulously monitored. According to the monitoring results, the positions of the sleeve 141 and the inner rod 146 are flexibly adjusted, and the length of the support leg 14 is changed until the device reaches a highly accurate level.

[0051] Once the device reaches the desired level, the rotating component 1412 is rotated in the opposite direction. As the rotating component 1412 rotates in the opposite direction, the elastic pad reapplies pressure to the sleeve 141, and the limiting component 1411 also resumes pressure on the inner rod 146, fixing the length of the support leg 14. This ensures that the device is stable and reliable after depth leveling, laying a solid foundation for subsequent latitude and longitude measurement operations.

[0052] The latitude and longitude measurement operation stage

[0053] Install the theodolite on the rotating platform 2 and ensure it is stable. Adjust the direction of the instrument through the rotating platform 2 to accurately align it with the building part to be measured. Then start the instrument to measure and record the relevant data.

[0054] Device storage stage

[0055] After the test, carefully disassemble and properly store the theodolite. Rotate the rotating part 1412 in the opposite direction to restore the length of the support leg 14 to its initial state, and at the same time, the contact pad 149 disengages from the limiting groove 1410 and returns to its original position. Finally, by sliding the positioning plate 12 upward, the support leg 14 can automatically retract, which greatly facilitates the handling and storage of the device.
