Description

Technical Field

[0001] This utility model relates to the field of engineering cost surveying technology, specifically to a construction engineering cost on-site surveying device. Background Technology

[0002] In the early stages of construction project preparation, it is necessary to estimate the construction cost. During on-site surveying, various surveying devices are used to collect data on the area and topography of the construction site. Total stations are commonly used for cost estimation. A total station is a high-precision surveying instrument used for topographic surveying, building surveying, and engineering surveying. Using laser technology, total stations achieve high-precision three-dimensional coordinate measurement and are widely used for surveying and positioning at construction sites.

[0003] In the current total station, the leveling process usually requires the operator to manually move each leg and adjust the angle of the legs to perform rough leveling. This process is cumbersome and inefficient. The operator needs to spend a lot of time and energy to ensure the level of the total station, which increases the inconvenience and complexity of the surveying work. Moreover, when the legs are moved, the tripod is unstable and is prone to tipping over, which can damage the equipment. Utility Model Content

[0025] 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.

[0026] Please see Figures 1 to 5 This utility model provides a technical solution: a construction engineering cost on-site surveying device, including a total station 8, a mounting plate 3 and a support rod 4, with a telescopic box 1 fixedly connected to the top of the support rod 4, and the top of the telescopic box 1 being hinged to the bottom of the mounting plate 3 through a hinge block 2;

[0027] like Figure 3 and Figure 4 As shown, the bottom of the hinge block 2 is provided with a coarse adjustment rack 19 that is inserted into the telescopic box 1. The middle of the telescopic box 1 is provided with a coarse adjustment box 18. The inside of the coarse adjustment box 18 is provided with a coarse adjustment gear 23 that meshes with the coarse adjustment rack 19. The middle of the coarse adjustment gear 23 is keyed to a rotating shaft 22. One end of the rotating shaft 22 passes through the coarse adjustment box 18 and is keyed to a coarse adjustment handwheel 16.

[0028] like Figure 4As shown, the side wall of the coarse adjustment box 18 has a sliding groove 24, and a sliding block 25 is slidably connected inside the sliding groove 24. A round hole is opened in the middle of the sliding block 25, which is fitted outside the rotating shaft 22. A locking gear 26 is integrally formed on the side of the coarse adjustment handwheel 16 near the sliding block 25. A toothed hole is opened on the outer wall of the sliding block 25 to accommodate the locking gear 26. After the locking gear 26 enters the toothed hole, it is engaged and locked, so that the locking gear 26 can no longer rotate. A lower pressure block 21 is movably sleeved on the outside of the rotating shaft 22. A spring cylinder 15 is provided on the side wall of the coarse adjustment box 18. A lower pressure spring 20 is provided inside the spring cylinder 15 to press the lower pressure block 21 against the coarse adjustment rack 19. The other end of the rotating shaft 22 passes through the coarse adjustment box 18 and is threadedly connected to a fastening cap 28. The pressure of the lower pressure spring 20 ensures that the coarse adjustment gear 23 and the coarse adjustment rack 19 can be stably engaged. After engagement, the position of the rotating shaft 22 is fixed by tightening the fastening cap 28.

[0029] like Figure 2 As shown, the bottom structure is the same as that of the existing technology of Nanfang Kelida NTS-362r10u. The bottom of the total station 8 is provided with a top plate 10, and the top of the mounting plate 3 is provided with a base plate 11. Three studs 13 are arranged in a ring array between the base plate 11 and the top plate 10. The top of the studs 13 is threaded to the top plate 10, and the bottom of the studs 13 is connected to the base plate 11 through a bearing. A fine adjustment wheel 12 is provided in the middle of the studs 13. A bubble level 9 is provided in the middle of the total station 8, and a circular level bubble 14 is provided on one side of the top of the top plate 10.

[0030] By setting up the telescopic box 1 and the hinge block 2, the distance between the telescopic box 1 and the hinge block 2 can be adjusted by rotating the coarse adjustment handwheel 16, and the position of the mounting plate 3 can be adjusted if it is too low. This allows the total station 8 to be coarsely leveled without moving the support rod 4. The operation is simple, time-saving and labor-saving, and at the same time, it can ensure the stability of the tripod and prevent the tripod from tipping over during adjustment.

[0031] A wedge rod 17 is movably inserted into the bottom of the telescopic box 1. The end of the wedge rod 17 is designed to lift the rotating shaft 22. A spring 27 is provided in the middle of the wedge rod 17 to push the wedge rod 17 away from the rotating shaft 22. A telescopic rod 5 is slidably connected inside the support rod 4. After the telescopic rod 5 is shortened, it can press the wedge rod 17 into the telescopic box 1. A limiting frame 6 is provided at the bottom of the support rod 4 and sleeved on the outside of the telescopic rod 5. A fastening bolt 7 for locking the telescopic rod 5 is threadedly connected to the side wall of the limiting frame 6.

[0032] By setting the wedge rod 17, after the survey is completed, the wedge rod 17 can be pressed into the telescopic box 1 by retracting the telescopic rod 5, which releases the limit of the coarse adjustment gear 23 on the coarse adjustment rack 19, so that the coarse adjustment rack 19 can be retracted into the telescopic box 1 when the tripod is in the storage state, so as to facilitate the extension and leveling of the coarse adjustment rack 19 when the tripod is set up again.

[0033] Working principle: When the tripod is unfolded, the telescopic rod 5 is extended to ensure that the mounting plate 3 is as horizontal as possible. The extension length of the telescopic rod 5 is fixed by the fastening bolt 7. The bottom of the base plate 11 is connected to the mounting plate 3 by bolts. After the total station 8 is installed, coarse leveling is required. By observing the bubble inside the circular level bubble 14, the support rod 4 on the side away from the bubble needs to be lengthened to level the mounting plate 3.

[0034] During coarse leveling, pull out the coarse adjustment handwheel 16 to disengage the locking gear 26 from the sliding block 25. At this time, the rotating shaft 22 will also slide inside the lower pressure block 21. By rotating the coarse adjustment handwheel 16, the coarse adjustment gear 23 and the coarse adjustment rack 19 are engaged to adjust the coarse adjustment rack 19 out, so that the telescopic box 1 and the hinge block 2 are far apart. At this time, the lower side of the mounting plate 3 can be adjusted up until the bubble inside the circular level bubble 14 is in the center circle. By pressing the coarse adjustment handwheel 16, the locking gear 26 is retracted into the tooth groove. The engagement prevents the locking gear 26 from rotating, thereby fixing the length of the coarse adjustment rack 19.

[0035] Then, by rotating the fine adjustment wheel 12 to finely level the top plate 10, after the bubble in the bubble level 9 is centered, rotate the total station 8 ninety degrees and adjust the fine adjustment wheel 12 again to make the bubble in the bubble level 9 centered again, thus completing the leveling process.

[0036] When storing the tripod, the telescopic rod 5 needs to be retracted. When the telescopic rod 5 is retracted to its shortest length, the wedge rod 17 will be pressed into the inside of the wedge rod 17. The wedge shape at the end of the wedge rod 17 will move the rotating shaft 22 upward. At the same time, the sliding block 25 will also slide inside the sliding groove 24, so that the coarse adjustment gear 23 is no longer engaged with the coarse adjustment rack 19, and the coarse adjustment rack 19 can be fully retracted into the telescopic box 1.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
