Description

Technical Field

[0001] This utility model relates to the field of total station measurement technology, specifically an adjustable support frame for a total station. Background Technology

[0002] In the field of downhole engineering surveying, total station surveying is a key technical means to obtain accurate spatial data. During the surveying operation, the high accuracy of the instrument's measurements plays a decisive role in the precision of the measurement results.

[0003] For example, Chinese Patent Application No. 201620283359.9 discloses a total station, which includes a total station body and a tripod. A sliding extension arm and a connecting screw for connecting the total station body are provided on the base of the tripod. The connecting screw includes a rotating part and a connecting part that is circumferentially limited on the rotating part and can extend and retract axially. An elastic element is provided between the connecting part and the rotating part so that the top of the connecting part protrudes from the base. It has the advantages of being very simple and quick to align and install the total station body and the tripod.

[0004] In traditional underground surveying operations, it is necessary to measure the total station's elevation while simultaneously operating the instrument. However, due to the complex underground environment (such as confined spaces, dim lighting, and varied tunnel undulations), measuring the total station's elevation requires manually measuring the distance from the instrument's center to the tunnel roof control point using a steel tape measure. In superelevated and inclined tunnels, the tape measure is prone to bending and reading angle deviations, introducing errors. Furthermore, surveyors typically need to use ladders, extension poles, and other auxiliary tools, which not only requires multiple people, is cumbersome and inefficient, but also poses a risk of falls. Additionally, when measuring tunnel roof control points with a traditional total station, the limitations of the instrument's structure and installation make it difficult for surveyors to quickly and accurately align the total station's infrared aiming point with the roof control point. This further increases the difficulty and error risk of the measurement, severely hindering the efficient implementation of underground surveying work.

[0005] Therefore, it is necessary to redesign and modify the adjustable support frame of the total station to effectively prevent large human errors, low efficiency, and slow alignment. Utility Model Content

The lower side of the fixed box 12 is fixedly connected to the upper side of the base 5. The worm 10 is rotatably connected to the inner wall of the fixed box 12 through a bearing. Thus, manually rotating the worm 10 can drive the rotating rod 6 to rotate. It also has a self-locking property, thereby precisely adjusting the rotation angle. A universal mechanism is provided on the upper side of the rotating rod 6.

[0027] As a technical optimization of this utility model, by setting a rotation angle control mechanism, the rotating rod 6 can be stably maintained at the adjusted angle, avoiding angle deviation caused by external force, realizing precise angle adjustment, and meeting the requirements of high-precision measurement.

[0028] refer to Figure 4 The universal mechanism includes a base 13 fixedly connected to the upper end of the rotating rod 6, a universal ball 14 slidably connected to the inner wall of the base 13, a tension adjustment knob 15 installed on the front side of the base 13, and a clamping mechanism provided on the upper side of the universal ball 14.

[0029] As a technical optimization of this utility model, by setting a universal mechanism, the component installed on the upper side of the universal ball 14 can rotate flexibly in multiple directions. The tightness adjustment knob 15 can conveniently control the rotation tightness of the universal ball 14, which can not only ensure that it can rotate easily when the angle needs to be adjusted, but also fix it firmly after adjusting to a suitable angle, thus further improving the flexibility and accuracy of measurement.

[0030] refer to Figure 4 The clamping mechanism includes a fixed frame 16 fixedly connected to the upper side of the universal ball 14. Two sliding rods 17 are slidably connected inside the fixed frame 16. Fixed clamps 18 are fixedly connected to the ends of the sliding rods 17 that are close to each other. The fixed clamps 18 together hold the miniature rangefinder 19 inside. Linkage plates 20 are fixedly connected to the ends of the sliding rods 17 that are far from each other. Tension springs 21 are fixedly connected to the inside of the linkage plates 20. The other end of the tension springs 21 is fixedly connected to the surface of the fixed frame 16. A laser sight 22 is fixedly connected to the upper side of the fixed frame 16. The laser sight 22 is used to assist the miniature rangefinder 19 in measuring distance.

[0031] As a technical optimization of this utility model, by setting a clamping mechanism, the clamping clip 18 automatically clamps the miniature rangefinder 19 using the action of the tension spring 21, making installation and disassembly convenient and quick; at the same time, the laser aiming device 22 can assist the miniature rangefinder 19 in measuring distance, providing operators with a more accurate aiming reference and improving the accuracy and efficiency of measurement.

[0032] refer to Figure 5 A toggle plate 23 is fixedly connected to the rear side of the linkage plate 20. The toggle plates 23 are used to press and move against each other, thereby controlling the fixing clamp 18 to release its fixation to the miniature rangefinder 19.

[0033] As a technical optimization of this utility model, by setting a toggle plate 23, the operator can control the fixing clip 18 to release the fixing of the miniature rangefinder 19 by pressing the toggle plate 23 with each other. No other tools are needed, the operation is simple and convenient, and it is easy to quickly replace or remove the miniature rangefinder 19.

[0034] refer to Figure 3 An angle adjustment knob 24 is fixedly connected to the right end of the worm gear 10. The angle adjustment knob 24 allows the operator to rotate the worm gear 10 with their fingers.

[0035] As a technical optimization of this utility model, by setting an angle adjustment knob 24, a convenient manual operation component is provided for the operator, enabling the operator to rotate the worm gear 10 more easily and comfortably, thereby improving the convenience and comfort of operation.

[0036] refer to Figure 3 A stabilizing cylinder 25 is fixedly connected to the upper side of the fixed box 12. The inner wall of the stabilizing cylinder 25 is slidably connected to the surface of the rotating rod 6. The stabilizing cylinder 25 provides radial support to the rotating rod 6, thereby increasing the stability of the rotation of the rotating rod 6.

[0037] As a technical optimization of this utility model, by setting the stabilizing cylinder 25, the rotating rod 6 is provided with radial support, which can effectively reduce the swaying and offset of the rotating rod 6 during the rotation process and increase the stability of the rotating rod 6.

[0038] refer to Figure 4 The inner side of the fixing clip 18 is fixedly connected to a spacer 26, which is made of rubber and has elasticity and anti-slip properties.

[0039] As a technical optimization of this utility model, by setting a spacer 26, the miniature rangefinder 19 is prevented from slipping due to vibration during the measurement process, thus ensuring the installation stability and measurement accuracy of the miniature rangefinder 19.

[0040] The working principle and usage of this utility model are as follows: Based on a total station 1, this device achieves 360-degree horizontal adjustment and precise positioning of the miniature rangefinder 19 through a support and rotation mechanism on the bracket 2. In the support and rotation mechanism, the clamp 3 fixes the extension arm 4 to the bracket 2, and the rotating rod 6 inside the base 5 can rotate under the action of the bearing. In the rotation angle control mechanism, manually rotating the angle adjustment knob 24 drives the worm gear 10 to rotate, the worm gear 10 drives the worm wheel 9 to rotate, the worm wheel 9 drives the gear 8, and the gear 8 then drives the rotating rod 6 to rotate through the gear ring 7. Due to the self-locking characteristics of the worm wheel 9 and worm gear 10, when the angle adjustment knob 24 is stopped, the rotating rod 6 can stably maintain the current angle, achieving precise angle adjustment. In the universal mechanism at the upper end of the rotating rod 6, the universal ball 14 can rotate flexibly within the base 13, and the tightness of the universal ball 14 can be controlled by the tension adjustment knob 15. In the clamping mechanism on the upper side of the omnidirectional ball 14, the tension spring 21 brings the two sliding rods 17 closer together, causing the fixing clamp 18 to clamp the miniature rangefinder 19. The laser sight 22 assists the miniature rangefinder 19 in measuring distance. Pressing the toggle plate 23 causes the linkage plate 20 to move the sliding rods 17 away from each other, thereby releasing the miniature rangefinder 19 from the fixing clamp 18. The stabilizing cylinder 25 provides radial support for the rotating rod 6, increasing the stability of the rotation of the rotating rod 6. This enables a rapid three-step measurement operation, namely, an integrated operation of "aiming-distance measurement-height measurement". It avoids the large errors and high safety caused by the need for manual climbing and operation in traditional measurement processes, giving it the advantage of being easy to measure.

[0041] In summary, when this utility model is used, under the action of the supporting rotation mechanism, rotation angle control mechanism, universal mechanism and clamping mechanism, it can quickly measure the height of the total station 1, avoiding the large errors caused by manual climbing and manual operation in the traditional measurement process and ensuring high safety, thus giving it the advantage of being easy to measure.
