Description

Technical Field

[0001] This utility model relates to the field of surveying instrument positioning technology, and in particular to a surveying instrument positioning device for engineering surveying. Background Technology

[0002] In the field of modern engineering construction, surveying and mapping work, as a fundamental link in engineering planning, design, and construction, places extremely high demands on the accuracy and reliability of surveying data. The positioning device of the surveying instrument, as a key piece of equipment ensuring the smooth progress of surveying work, directly affects the quality of the surveying results. With the continuous expansion of infrastructure construction, the increasing complexity of terrain and landforms, and the changing environment of engineering sites, even more stringent challenges are posed to the adaptability, stability, and accuracy of the positioning device of the surveying instrument.

[0003] Currently, most common positioning devices for engineering surveying instruments adopt traditional bracket structures, using threaded knobs or simple clips for angle adjustment and fixation. These devices are typically based on the principle of rigid connection, relying on manual tightening or loosening of knobs to adjust the surveying instrument within a certain angle range, and attempting to maintain a fixed state through mechanical locking. During fine-tuning, the operator needs to repeatedly tighten multiple knobs to gradually determine the surveying instrument's orientation; after angle adjustment, the friction between the threads or the engagement of the clips maintains the surveying instrument's fixed posture.

[0004] However, this traditional positioning method has significant drawbacks. In actual engineering surveying scenarios, factors such as wind at the construction site, vibrations from heavy machinery operations, or accidental contact by operators make it difficult for traditional positioning devices to reliably lock the rotation angle of the surveying instrument. Any unexpected deviation of the surveying instrument significantly increases measurement angle errors, leading to deviations in the collected terrain data and building coordinates. These errors accumulate and amplify during subsequent data processing and engineering design, ultimately causing construction deviations, delays, increased costs, and even safety hazards. Therefore, this paper proposes a surveying instrument positioning device for engineering surveying to address these problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a positioning device for a surveying instrument in engineering surveying, which aims to improve the problem in the prior art where the inability to fix the angle causes the instrument to deviate unexpectedly during the measurement process, especially when there is wind, vibration or operational errors, which increases the angle error and affects the accuracy of the data.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A positioning device for an engineering surveying instrument includes a base and a surveying instrument. A universal ball is rotatably connected inside the base. A bracket is fixedly connected to the top of the universal ball. A connecting plate is rotatably connected to the side wall of the bracket. A connecting hollow column is fixedly connected to the top of the connecting plate. The bottom of the surveying instrument is set on the top of the connecting hollow column. A rotating shaft is rotatably connected inside the connecting hollow column. A gear is fixedly connected to the outer wall of the rotating shaft. A buckle assembly is provided inside the connecting hollow column.

[0008] The buckle assembly includes a collar, the outer wall of which is fixedly connected to the inside of the connecting hollow column. A handle is slidably connected inside the collar. A locking block is fixedly connected to one end of the handle. The side wall of the locking block is disposed on the outer wall of the gear. A first spring is sleeved on the outer wall of the handle. One end of the first spring is fixedly connected to one end of the collar, and the other end of the first spring is fixedly connected to the side wall of the locking block.

[0009] As a further description of the above technical solution:

[0010] A base plate is fixedly connected to the top of the connecting hollow column, and a second hollow plate is fixedly connected to the top of the base plate.

[0011] As a further description of the above technical solution:

[0012] The second hollow plate is slidably connected to the side wall of the first hollow plate, and a connecting hollow column is fixedly connected to the top of the first hollow plate. The top of the connecting hollow column is fixedly connected to the bottom of the surveyor.

[0013] As a further description of the above technical solution:

[0014] The second hollow plate has a sliding column slidably connected inside, and a button is fixedly connected to one end of the sliding column.

[0015] As a further description of the above technical solution:

[0016] A fixing ring is fixedly connected to the outer wall of the sliding column, and the outer wall of the fixing ring is slidably connected inside the second hollow plate.

[0017] As a further description of the above technical solution:

[0018] A locking post is fixedly connected to the outer wall of the fixed ring, and the outer wall of the locking post is slidably connected to the inside of the second hollow plate. The outer wall of the locking post is located inside the first hollow plate.

[0019] As a further description of the above technical solution:

[0020] A baffle is fixedly connected to one end of the sliding column, and the outer wall of the baffle is slidably connected to the inside of the second hollow plate.

[0021] As a further description of the above technical solution:

[0022] The side wall of the baffle is provided with a second spring, and both ends of the second spring are fixedly connected to the side wall of the baffle.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, by pulling the handle, the locking block is slid inside the connecting hollow column. Then, the handle is subjected to force, causing the side wall of the locking block to disengage from the outer wall of the gear, thereby achieving the effect of locking the rotation angle of the surveyor. This solves the problem that the inability to fix the angle causes the instrument to deviate unexpectedly during the measurement process, especially when there is wind, vibration or operational errors, which increases the angle error and affects the accuracy of the data. This improves the practicality of the surveyor positioning device.

[0025] 2. In this utility model, the sliding column is moved by pulling the button, and then the sliding column is forced to move the fixing ring and the locking column together. At the same time, the outer wall of the locking column is separated from the inner wall of the first hollow plate, which achieves the effect of quickly disassembling the surveyor. This solves the problem of cumbersome assembly required for each use, which reduces work efficiency and affects the response speed of emergency tasks, and improves the convenience of the surveyor positioning device.

Detailed Implementation

[0033] 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.

[0034] Reference Figures 1-4 This utility model provides an embodiment of a surveying instrument positioning device for engineering surveying, including a base 6 and a surveying instrument 1. A universal ball 5 is rotatably connected inside the base 6. A bracket 4 is fixedly connected to the top of the universal ball 5. A connecting plate 3 is rotatably connected to the side wall of the bracket 4. A connecting hollow column 2 is fixedly connected to the top of the connecting plate 3. The bottom of the surveying instrument 1 is set on the top of the connecting hollow column 2. A rotating shaft 7 is rotatably connected inside the connecting hollow column 2. A gear 8 is fixedly connected to the outer wall of the rotating shaft 7. A buckle assembly is provided inside the connecting hollow column 2. The buckle assembly consists of a collar 10, a handle 9, a locking block 11, and a first spring 12, which is used to unlock the rotating shaft 7 with one key, thereby improving the efficiency of angle adjustment. Further details are omitted here.

[0035] The buckle assembly includes a collar 10, the outer wall of which is fixedly connected to the inside of the connecting hollow column 2. A handle 9 is slidably connected inside the collar 10. A locking block 11 is fixedly connected to one end of the handle 9. The locking block 11 is wedged into the tooth groove under the elastic force of the first spring 12 to form a self-locking angle constraint. The side wall of the locking block 11 is set on the outer wall of the gear 8. The outer wall of the handle 9 is fitted with the first spring 12. One end of the first spring 12 is fixedly connected to one end of the collar 10, and the other end of the first spring 12 is fixedly connected to the side wall of the locking block 11.

[0036] Reference Figure 1 and Figure 5A base plate 15 is fixedly connected to the top of the hollow column 2. A second hollow plate 14 is fixedly connected to the top of the base plate 15. A first hollow plate 13 is slidably connected to the side wall of the second hollow plate 14. The hollow column 2 is fixedly connected to the top of the first hollow plate 13. The top of the hollow column 2 is fixedly connected to the bottom of the surveyor 1. A sliding column 16 is slidably connected inside the second hollow plate 14. A button 17 is fixedly connected to one end of the sliding column 16. Pressing the button 17 drives the sliding column 16 to compress the second spring 21, causing the locking column 19 to exit the positioning hole, thus releasing the height lock. A fixing ring 18 is fixedly connected to the outer wall of the sliding column 16. The outer wall of the fixing ring 18 is slidably connected to the inside of the second hollow plate 14. The outer wall of the fixing ring 18 is fixedly connected to the locking post 19. The outer wall of the locking post 19 is slidably connected to the inside of the second hollow plate 14. The outer wall of the locking post 19 is set inside the first hollow plate 13. One end of the sliding post 16 is fixedly connected to the baffle 20. The outer wall of the baffle 20 is slidably connected to the inside of the second hollow plate 14. The side wall of the baffle 20 is provided with a second spring 21. After the release button 17 is released, the second spring 21 pushes the baffle 20 to reset, so that the outer wall of the locking post 19 self-aligns and inserts into the positioning hole, realizing instantaneous locking. Both ends of the second spring 21 are fixedly connected to the side wall of the baffle 20.

[0037] Working Principle: When using the positioning device of the surveying instrument for engineering surveying, firstly, under the elastic force of the first spring 12, the side wall of the locking block 11 is tightly engaged in the tooth groove of the outer wall of the gear 8, restricting the rotation of the rotating shaft 7, thereby fixing the surveying instrument 1 at the current angle. When the angle needs to be adjusted, the operator pulls the handle 9, which slides inside the collar 10, causing the locking block 11 to overcome the elastic force of the first spring 12, so that the side wall of the locking block 11 disengages from the tooth groove of the outer wall of the gear 8. At this time, the rotating shaft 7 is no longer restricted and can rotate freely, and the surveying instrument 1 is adjusted to the appropriate angle. After the adjustment is completed, the handle 9 is released, the first spring 12 returns to its deformation, and pushes the locking block 11 back into the tooth groove of the gear 8, realizing the locking of the rotation angle of the surveying instrument 1, effectively preventing the instrument from accidentally shifting due to factors such as wind, vibration or operational errors, and ensuring the accuracy of the measurement data.

[0038] Subsequently, when it is necessary to disassemble the surveyor 1, push button 17. Button 17 causes sliding column 16 to slide inside the second hollow plate 14. Simultaneously, sliding column 16 causes fixing ring 18 and locking column 19 to move, causing the outer wall of locking column 19 to disengage from the inner wall of the first hollow plate 13. At this time, the connection between surveyor 1 and positioning device is released, and surveyor 1 can be removed from the top of connecting hollow column 2, achieving quick disassembly. When installing surveyor 1, align the bottom of surveyor 1 with the top of connecting hollow column 2 and press down. When the first hollow plate 13 is aligned with the second hollow plate 14, the second spring 21 pushes the baffle 20 and sliding column 16 to reset, and locking column 19 is reinserted into the first hollow plate 13, completing the quick installation of surveyor 1.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
