Description

Technical Field

[0001] The invention relates to the technical field of engineering surveying instruments, in particular to a high-precision positioning surveying instrument for engineering surveying. Background Art

[0002] Surveying instruments are often used in the construction process. Surveying instruments can accurately measure various physical parameters of the surface, such as distance, angle, elevation, slope and direction. This precise measurement capability enables engineers to accurately obtain geographic spatial data, thereby conducting effective engineering planning and design. At present, the positioning equipment of surveying instruments is generally a tripod device;

[0003] When the current engineering surveying instrument is in use, the tripod at the bottom of the surveying instrument on the market can be fixed by simply spreading the bottom and then inserting it into the ground. The staff can then use the surveying instrument. However, when this setting is used in outdoor engineering sites, due to the strong outdoor wind, it is very easy to cause the surveying instrument to shake during detection, resulting in deviations in detection and poor accuracy. At the same time, when the surveying instrument is fixed on the tripod, the surveying instrument can only be adjusted horizontally at normal levels, which is relatively simple to use and has poor practicality.

[0004] In view of the above problems, the inventor proposes a high-precision positioning surveying instrument for engineering surveying to solve the above problems. Summary of the invention

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] like Figure 1-9 As shown, the present invention provides a high-precision positioning surveying instrument for engineering surveying, comprising a base 1, an instrument body 11 is installed on the upper surface of the base 1, a bottom plate 12 arranged in a circular shape is provided directly below the base 1, an adjustment component is provided between the bottom plate 12 and the base 1, support feet 13 arranged in a ring-shaped distribution are hingedly connected at the edge of the lower surface of the bottom plate 12, a vertically arranged screw rod 14 is rotatably provided at the center of the lower surface of the bottom plate 12, a moving sleeve 15 is threadedly sleeved on the screw rod 14, a support plate 16 is provided directly below the bottom plate 12, a moving block 17 is slidably inserted at the edge of the support plate 16, a push rod 18 is hingedly provided between the moving block 17 and the moving sleeve 15, a rotating rod 19 is movably inserted at the bottom of the screw rod 14, the bottom of the rotating rod 19 is rotatably inserted on the support plate 16 through a bearing, and a driving component is provided between the rotating rod 19 and the screw rod 14.

[0028] A first gear 141 is fixedly provided on the top of the screw rod 14, a second gear 142 meshing with the first gear 141 is provided on the lower surface of the base plate 12, a drive motor 143 is fixedly provided on the lower surface of the base plate 12 below the first gear 141, and an output end of the drive motor 143 is coaxially fixed on the second gear 142.

[0029] By adopting the above technical solution, the drive motor 143 can provide power for the rotation of the screw rod 14, which is convenient for operation and easy for staff to control.

[0030] The driving assembly includes a movable plate 2, which is slidably inserted in the rotating rod 19. A groove 21 is provided inside the rotating rod 19, and the movable plate 2 is rotatably inserted in the groove 21. A vertically arranged upright rod 22 is fixedly provided at one end of the movable plate 2 located inside the groove 21, and a fixed plate 23 is fixedly provided above the inner part of the groove 21. The upper end of the upright rod 22 penetrates the fixed plate 23, and an inclined swinging plate 24 is fixedly provided on the upper surface of the fixed plate 23 at both ends of the upright rod 22. A protruding block 25 is fixedly provided on the top of the swinging plate 24, and the block 25 can penetrate the rotating rod and be inserted inside the screw rod 14. A first spring 26 is commonly connected between the two blocks 25. The top of the upright rod 22 is hingedly connected to the block 25 by a connecting rod 27. A vertically arranged top rod 151 is fixedly provided on the lower surface of the movable sleeve 15, and the top rod 151 can be abutted against the movable plate 2.

[0031] By adopting the above technical solution, firstly, the movable block 17 can be adjusted to move away from the support plate 16 to increase the stability of the bottom support of the device. At the same time, the overall downward movement of the support plate 16 can lower the center of gravity of the entire device, and the device is less likely to tip over when subjected to external force.

[0032] A second spring 28 is fixedly disposed on the lower surface of the movable plate 2 located inside the groove 21 , and the second spring 28 is fixedly connected to the bottom of the groove 21 .

[0033] By adopting the above technical solution, the second spring 28 can push the movable plate 2 back to its original position when the top rod 151 is no longer in contact with the movable plate 2. At this time, the vertical rod 22 will no longer pull the two blocks 25, so that the blocks 25 can be directly inserted into the inside of the screw rod 14 again, completely fixing the connection between the rotating rod 19 and the screw rod 14. During subsequent recovery, the screw rod 14 can rotate to drive the bottom support plate 16 to move upward to complete the recovery.

[0034] Two symmetrically arranged ground-inserting rods 3 are movably inserted at one end of the moving block 17 away from the supporting plate 16 , and a horizontal plate 31 is fixedly arranged between the tops of the two ground-inserting rods 3 on the moving block 17 .

[0035] By adopting the above-mentioned technical scheme, the provided ground-inserting rod 3 can be stably inserted into the ground, thereby increasing the overall stability of the device. At the same time, the provided cross plate 31 can directly connect the two ground-inserting rods 3, making it convenient for subsequent staff to directly control the two tasks and improve the convenience of operation. Specifically, the staff can directly press with their feet to insert the ground-inserting rod 3 into the ground.

[0036] A slot 32 corresponding to the supporting foot 13 is formed at the edge of the supporting plate 16 .

[0037] By adopting the above technical solution, when the support legs 13 are recovered, they are pressed into the card slots 32, so that the annularly distributed support legs 13 and the support plate 16 can be fixed, which is convenient for subsequent unified transportation and recovery.

[0038] The adjustment component includes an L-shaped fixed frame 4, a screw rod 47 is threadedly inserted at one vertical end of the fixed frame 4, a movable frame 41 is arranged in an inverted U shape on the fixed frame 4, and both ends of the movable frame 41 are slidably arranged on the side walls of the fixed frame 4, two pairs of first mounting blocks 43 are fixedly arranged at the lower surface of the base 1 near the fixed frame 4, and swing rods 42 are rotatably arranged at the opposite side walls of the two first mounting blocks 43, and one end of the swing rod 42 away from the first mounting block 43 is rotatably arranged on the movable frame 41, and two pairs of second mounting blocks 44 are fixedly arranged at the upper surface of the bottom plate 12 near the corresponding first mounting blocks 43, and a U-shaped swing frame 45 is rotatably arranged between the two adjacent second mounting blocks 44, and both ends of the swing frame 45 are rotatably arranged on the swing rod 42 through a cross bar 46.

[0039] By adopting the above technical solution, when the screw 47 rotates, the rotating screw 47 will directly drive the threaded movable frame 41 to move. At this time, the movable frame 41 driven to move will directly drive the swing rod 42 and the swing frame 45 to drive the first mounting block 43 to move upward. After the above operation, when the driving wheel 5 rotates, the base 1 as a whole can be driven to be adjusted in the horizontal direction.

[0040] The number of the fixing frames 4 is four and they are arranged in a rectangular shape, wherein two fixing frames 4 are symmetrically distributed.

[0041] By adopting the above technical solution, such an arrangement can adjust the two sides of the base 1, thereby improving the practicality of the actual operation of the device.

[0042] A transmission shaft 48 is provided at one end of the screw rod 47 away from the second mounting block 44 . The transmission shaft 48 and the screw rod 47 are connected via two meshing bevel gears 49 . One end of the transmission shaft 48 extends to the outside of the base 1 .

[0043] By adopting the above technical solution, the transmission shaft 48 and the two meshing bevel gears 49 drive the screw 47 to rotate, so that the staff can directly operate outside the base 1, thereby improving the convenience of operation.

[0044] A rotating wheel 5 with an anti-slip strip on the outer wall is fixedly provided at one end of the transmission shaft 48 located outside the base 1 .

[0045] By adopting the above technical solution, the rotating wheel 5 can be conveniently driven by the staff, thereby improving the convenience of operation.

[0046] Working principle: During use, when the device needs to work in the required surveying and mapping work area, the support legs 13 can be spread out so that the annular support legs 13 can support the upper base 1 and the surveying and mapping instrument body 11. At the same time, the driving motor 143 can directly drive the second gear 142 to drive the first gear 141 to rotate. The rotating first gear 141 will drive the screw rod 14 to rotate. At this time, the moving sleeve 15 threadedly arranged on the rotating screw rod 14 will be driven by the screw rod 14 to move downward. At this time, the push rod 18 hingedly arranged between the moving sleeve 15 and the moving block 17 will directly push the moving block 17 to gradually move out to the support plate 16. As the movable sleeve 15 gradually moves downward, when the top rod 151 on the movable sleeve 15 moves downward and abuts against the movable plate 2 on the rotating rod 19, the movable plate 2 will be pushed downward, and the movable plate 2 that moves downward will drive the vertical rod 22 to move downward together. At this time, the connecting rod 27 hingedly arranged between the vertical rod 22 and the card block 25 will pull the card block 25 to move into the groove 21. At this time, the rotating rod 19 and the screw rod 14 will be separated and unfixed. At this time, as the movable sleeve 15 moves downward again, the downward moving sleeve 15 will directly drive the rotating rod 19 to move downward as a whole. At this time, the movable sleeve 15, the push rod 18, the support plate 16 and the moving block 17 move downward as a whole, and adjust their own gravity to move downward;

[0047] When it is necessary to adjust the surveying instrument body 11 arranged above the base 1, the staff can drive the two rotating wheels 5 respectively, and the rotating wheels 5 can drive the transmission shaft 48 to rotate, thereby driving the screw 47 to rotate. At this time, the rotating screw 47 will directly drive the threaded movable frame 41 to move. At this time, the movable frame 41 driven to move will directly drive the swing rod 42 and the swing frame 45 to drive the first mounting block 43 to move upward. After the above operation, when the driving wheel 5 rotates, the base 1 can be driven to be adjusted in the horizontal direction as a whole. At the same time, the fixed frames 4 are symmetrically distributed, so that the two rotating wheels 5 can respectively control the adjustment of the horizontal angles of the two ends of the base 1, so that when the surveying instrument body 11 is used, more various angle adjustments can be made to it, which can meet the needs of more sufficient adjustments in actual use and more satisfactory adjustments.

[0048] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
