Description

Technical Field

[0001] This utility model belongs to the field of engineering surveying technology, and in particular relates to a novel total station positioning component. Background Technology

[0002] Total stations are the cornerstone tools of modern engineering surveying and topographic mapping. They perfectly integrate angle measurement, distance measurement, coordinate calculation and data processing. With their advantages of high precision, high efficiency, multi-functionality and digitalization, they play an irreplaceable core role in many fields such as construction, surveying, mining, water conservancy, transportation, industry, and monitoring. During use, total stations need to be fixed and limited by positioning components to ensure their measurement accuracy.

[0003] A search revealed that publication number CN219263622U, with an application date of 2022.11.21, discloses a novel total station positioning component, including a connecting plate with a built-in level. Three sets of connecting seats at the lower end of the connecting plate are fitted with support rods. An adjustment component is located inside the mounting column at the lower end of the connecting plate, cooperating with the three sets of support rods. Each of the three sets of support rods has an extension component at one end. The extension component includes an extension rod and a first screw. A through groove is opened on the support rod, and the first screw is rotatably disposed within the support rod. One end of the extension rod slides through the support rod, and the other end of the first screw passes through a threaded hole in the extension rod. An auxiliary component is provided at the other end of the extension rod.

[0004] However, it still has the following drawbacks in practical use:

[0005] 1. The existing new total station positioning components adjust the length of the extension rod by using the first screw. However, this method is cumbersome, time-consuming and labor-intensive for operators, resulting in low work efficiency.

[0006] 2. Existing total station positioning components adjust the angle of the reinforcing rod using a worm gear and worm wheel. However, this method is cumbersome for operators, affecting work efficiency. Furthermore, the meshing connection between the worm gear and worm wheel results in poor stability of the reinforcing rod. Therefore, we provide a novel total station positioning component to solve the above problems. Utility Model Content

Detailed Implementation

[0030] 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 skilled in the art without creative effort are within the protection scope of the present utility model. Example 1

[0031] Please see Figures 1 to 4 This utility model is a novel positioning component for a total station, including a mounting platform 100 and a support frame 101 that is movably mounted on its bottom at even intervals along the circumference via hinges. An extension frame 102 is slidably mounted inside the support frame 101. A moving hole 101c is provided below the rear end face of the support frame 101. An installation groove 102c is provided at the bottom of one side wall of the extension frame 102. A limiting component 200 is provided outside the moving hole 101c. The limiting component 200 includes a fixing plate 201 that is bolted to the rear end face of the support frame 101 and a bidirectional telescopic rod 202 fixed inside the fixing plate 201.

[0032] Specifically, the front end face of the support frame 101 is arrayed with scale lines 101a from top to bottom, and a sliding hole 101b is opened at the center of the front end face of the support frame 101; a scale 102a is fixed on the top of the front end face of the extension frame 102, and a storage groove 102b is provided at the bottom of the other side wall of the extension frame 102; a locking hole 102d is opened on the rear end face of the extension frame 102, and an angle adjustment component 103 is provided at the center of the bottom of the mounting platform 100; springs 203 are sleeved on both ends of the outer wall of the bidirectional telescopic rod 202, and L-shaped push plates 204 are installed on the telescopic ends of the bidirectional telescopic rod 202; a T-shaped block 205 is fixed on the front end face of the L-shaped push plate 204, and the spring 203 is located between the fixed plate 201 and the L-shaped push plate 204.

[0033] Furthermore, the support frame 101 and its structure are provided with three sets. The extension frame 102 is slidably installed inside the support frame 101. The scale 102a passes through the sliding hole 101b and points to the scale line 101a. The locking hole 102d is an opening in the middle and openings extending from top to bottom on both sides. The angle adjustment component 103 is existing technology, so it will not be described in detail here. Under the elasticity of the spring 203, it can drive the T-shaped blocks 205 and L-shaped push plates 204 at both ends to move.

[0034] The operation process of this embodiment is as follows: The total station is installed on the surface of the mounting platform 100. Then, the angle adjustment component 103 is used to open the surrounding support frame 101 to a certain angle. When it is necessary to adjust the height of the total station and the mounting platform 100, the L-shaped push plates 204 at both ends are pushed towards the center position. The L-shaped push plates 204 are pressed against the bidirectional telescopic rod 202 and the spring 203. The movement of the L-shaped push plates 204 will move the T-shaped block 205 synchronously, so that the T-shaped block 205 will move out of the corresponding locking hole 102d, releasing the extension frame 1. The limiting effect of 02 is then applied by pulling down the extension frame 102. The extension frame 102 slides along the inside of the support frame 101 under the force, thereby adjusting the height of the mounting platform 100. After the extension length of the extension frame 102 is adjusted, the force applied to the L-shaped push plate 204 is stopped. At this time, under the elastic recovery action of the spring 203, the T-shaped block 205 pops out and is locked in the corresponding card hole 102d, which plays a limiting role for the extension frame 102. This makes it easy for the staff to quickly adjust the length of the extension frame 102, saving time and effort and increasing work efficiency. Example 2

[0035] Please see Figure 3 and Figure 5 Based on Embodiment 1, unlike the first embodiment, a support assembly 300 is provided. The support assembly 300 includes a rotating plate 301 disposed above the inside of the mounting groove 102c, and a first rotating shaft 301a fixed at the center of the inner wall of the rotating plate 301. The other end of the first rotating shaft 301a is rotatably mounted in a bearing on the inner wall of the mounting groove 102c. This solves the problem that in the existing new total station positioning assembly, the angle of the reinforcing rod is adjusted by worm gear and worm wheel during use. However, this method is cumbersome for operators and affects work efficiency. At the same time, the meshing connection between the worm gear and worm wheel results in poor stability of the reinforcing rod.

[0036] Specifically, an insert 302 is fitted on the outer wall of the first rotating shaft 301a, and a ratchet 303 is provided below the insert 302. A second rotating shaft 303a is fixed at the center of one side wall of the ratchet 303. The other end of the second rotating shaft 303a passes through the bearing on the mounting groove 102c and is connected to the support leg 304. The support leg 304 is located inside the storage groove 102b.

[0037] Furthermore, the rotating plate 301 and the insert 302 are both fixed on the first rotating shaft 301a, and the three can move synchronously. The insert 302 can limit the ratchet 303. The support leg 304 and the ratchet 303 are both fixed on the second rotating shaft 303a, and the three can move synchronously.

[0038] The operation process of this embodiment is as follows: After the support frame 101 and extension frame 102 are spread out, they are placed on the ground. Then, the support leg 304 is rotated backward. The support leg 304 rotates under the force of the second rotating shaft 303a, which rotates the ratchet 303. At this time, the insert 302 cannot limit the ratchet 303. However, when the support leg 304 and the ratchet 303 rotate in opposite directions, the insert 302 limits the ratchet 303. Therefore, the support leg 304 can be supported on the ground, improving stability. When it is necessary to retract the support leg 304, the rotating plate 301 is rotated. The rotating plate 301 rotates under the action of the first rotating shaft 301a, which rotates the insert 302. At this time, the insert 302 moves out of the outer wall of the ratchet 303 and releases the limiting effect on the ratchet 303. Then, the support leg 304 can be rotated in the opposite direction and stored in the storage slot 102b, which facilitates the worker to operate the support leg 304 quickly and improves work efficiency.
