Description

Technical Field

[0001] This invention belongs to the field of positioning device technology, and in particular relates to a mapping instrument positioning device for dam shoreline. Background Technology

[0002] Surveying instruments are tools and equipment used to measure the features and locations of the Earth's surface. They include various types of instruments such as total stations, levels, GPS receivers, and laser scanners. When using these instruments for measurement, a support is usually needed to position them to ensure the accuracy and stability of the measurement.

[0003] Current surveying equipment generally uses tripods as positioning devices. However, when surveying the shoreline of a dam, the existing tripods are difficult to set up stably due to the large inclination of the dam surface, which makes it inconvenient to use the surveying equipment.

[0004] To address these issues, the present invention provides a mapping instrument positioning device for dam shorelines, thereby solving the problems mentioned above. Summary of the Invention

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0006] The purpose of this invention is to provide a positioning device for a surveying instrument for dam shorelines. By unfolding four extension arms and then rotating four second handwheels to make all four support plates contact the ground, four fixing cones are then inserted into the soil through corresponding holes to fix the device, thus solving the problem that existing positioning devices are not convenient to fix on sloping ground.

[0007] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: The present invention is a mapping instrument positioning device for the shoreline of a dam, comprising a chassis, a base column and an adjustable column; the base column is fixedly connected to the top of the chassis, an angle adjustment component is provided between the adjustable column and the base column, a stabilizing component is provided on the outside of the chassis, and a supporting component is provided on the outside of the base column. The stabilizing assembly includes four extension arms, all of which are rotatably connected to the outside of the chassis and are equidistantly distributed along the outside of the chassis. A pedal is fixedly connected to the top of each extension arm, and a second threaded sleeve is fixedly connected inside the extension arm, with the second threaded sleeve close to the free end of the extension arm. A second screw is threaded into the inside of the second threaded sleeve, and a second handwheel is fixedly connected to the top of the second screw. A support plate is rotatably connected to the bottom of the second screw. The support assembly includes a slide block, which is movably fitted onto the outside of the base column. The slide block is rotatably connected to four extension arms by support rods. A third threaded sleeve is fixedly connected to the outside of the slide block and communicates with the slide block. A fixing screw is threaded into the inside of the third threaded sleeve. The outside of the base column is provided with an opening hole and a closing hole, and the closing hole is located above the opening hole.

[0008] The present invention is further configured such that the angle adjustment component includes a base, the base is fixedly connected to the top of the base column, a first rotating shaft is rotatably connected inside the base, a rotating seat is fixedly connected outside the first rotating shaft, a toothed plate is fixedly connected inside the base, and the top of the toothed plate is in the shape of a one-sixth arc, a second rotating shaft is rotatably connected inside the rotating seat, a gear and a worm gear are fixedly connected outside the second rotating shaft, and the gear meshes with the teeth on the top of the toothed plate, a worm is rotatably connected inside the rotating seat, and the worm meshes with the worm gear, and an adjustment handwheel is fixedly connected to one end of the worm located outside the rotating seat.

[0009] The present invention is further configured such that the adjustable column includes a frame, a first threaded sleeve is rotatably connected to the top of the frame, a first screw is threadedly sleeved inside the first threaded sleeve, a slider is fixedly connected to the bottom of the first screw and the slider is slidably connected inside the frame, a surveying instrument mounting base is fixedly connected to the top of the first screw, and a first handwheel is fixedly connected to the outside of the first threaded sleeve.

[0010] The invention is further configured such that scales are fixedly connected to both sides of the base, and pointers are fixedly connected to both ends of the first rotating shaft, with the two pointers corresponding to the two scales respectively.

[0011] The present invention is further configured such that a bottom cover is fixedly connected inside the base, and upper covers are fixedly connected to both sides of the rotating seat. The top of the bottom cover is arc-shaped, and both upper covers are movably sleeved on the outside of the bottom cover.

[0012] The invention is further configured such that an insertion hole is provided inside the extension arm, and a fixed cone is movably inserted into the insertion hole.

[0013] The invention is further configured such that a hexagonal hole is provided at the top of the fixed cone, and the lower half of the fixed cone is spiral-shaped.

[0014] The present invention has the following beneficial effects: 1. This invention involves unfolding four extension arms, which then pull the slide down via four support rods. When the slide reaches the bottom, fixing screws are screwed into the opening holes. Then, by rotating the second handwheel, the corresponding second screw rotates within the second threaded sleeve. Under the action of the threads, the second screw moves upward or downward, allowing all four support plates to contact the ground, thus making the device more stable. Finally, four fixing cones are inserted into the ground through corresponding holes to further secure the device.

[0015] 2. The invention can further increase the contact area with the ground by setting up a pedal, thereby avoiding sinking when working on softer ground, and also making it easier for workers to stand.

[0016] 3. In this invention, the rotating adjustment handwheel drives the worm gear to rotate, and then the worm gear drives the worm wheel to rotate. After that, the worm wheel drives the gear to roll on the top of the toothed plate through the second rotating shaft, thereby making the rotating seat rotate. This allows the installation angle of the surveying instrument to be adjusted on an inclined ground, making the adjustment of the surveying instrument more convenient.

[0017] 4. By rotating the first handwheel, the first threaded sleeve can be rotated. Then, under the action of the thread, the first screw and the slider can move up and down, thereby adjusting the height of the surveying instrument and making it more convenient for surveyors of different heights to use.

[0018] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0031] Example 1 Please see Figures 1 to 6 The present invention is a positioning device for a surveying instrument for the shoreline of a dam, comprising a chassis 100, a base column 200, and an adjustable column 300; the base column 200 is fixedly connected to the top of the chassis 100, an angle adjustment component 400 is provided between the adjustable column 300 and the base column 200, a stabilizing component 500 is provided on the outside of the chassis 100, and a supporting component 700 is provided on the outside of the base column 200; The stabilizing component 500 includes four extension arms 501, all of which are rotatably connected to the outside of the chassis 100 and are equidistantly distributed along the outside of the chassis 100. A pedal 502 is fixedly connected to the top of each extension arm 501, and a second threaded sleeve 503 is fixedly connected inside each extension arm 501. The second threaded sleeve 503 is close to the free end of the extension arm 501. A second screw 504 is threaded inside the second threaded sleeve 503. A second handwheel 505 is fixedly connected to the top of the second screw 504, and a support plate 506 is rotatably connected to the bottom of the second screw 504. By extending the four extension arms 501, the contact area with the ground can be increased, thereby making the invention more stable. The pedal 502 can further increase the contact area with the ground, thereby preventing sinking when working on softer ground and also making it easier for workers to stand. The support assembly 700 includes a slide 701, which is movably sleeved on the outside of the base column 200. The slide 701 is rotatably connected to the four extension arms 501 by support rods 702. A third threaded sleeve 703 is fixedly connected to the outside of the slide 701 and communicates with the slide 701. A fixing screw 704 is threaded inside the third threaded sleeve 703. The base column 200 has an opening hole 705 and a closing hole 706 on its outside, and the closing hole 706 is located above the opening hole 705. The four extension arms 501 can be supported by the four support rods 702.

[0032] Specifically, the extension arm 501 has an insertion hole 508 inside, and a fixing cone 507 is movably inserted into the insertion hole 508. The fixing cone 507 can further increase the stability of the present invention when standing.

[0033] Furthermore, the top of the fixing cone 507 is provided with a hexagonal hole, and the lower half of the fixing cone 507 is spiral-shaped. The spiral-shaped fixing cone 507 can make the fixing cone 507 more stable and also make it easier to remove.

[0034] The operation process of this embodiment is as follows: When it is necessary to support the surveying instrument, firstly, unscrew the fixing screw 704 from the retracting hole 706, then unfold the four extension arms 501, and then the four extension arms 501 pull the slide block 701 down through the four support rods 702. After the slide block 701 slides down to the bottom, screw the fixing screw 704 into the opening hole 705. Then, by rotating the second handwheel 505, the corresponding second screw 504 is driven to rotate in the second threaded sleeve 503. Then, under the action of the thread, the second screw 504 moves upward or upward, so that the four support plates 506 can all contact the ground, thereby making the device more stable. Then, insert the four fixing cones 507 through the corresponding insertion holes 508 into the ground, thereby further fixing the device.

[0035] Example 2 Please see Figure 1 , Figure 2 and Figure 5 Based on the first specific embodiment, the angle adjustment component 400 includes a base 401, which is fixedly connected to the top of the base column 200. A first rotating shaft 402 is rotatably connected inside the base 401, and a rotating seat 404 is fixedly connected to the outside of the first rotating shaft 402. A toothed plate 403 is fixedly connected inside the base 401, and the top of the toothed plate 403 is a one-sixth arc shape. A second rotating shaft 405 is rotatably connected inside the rotating seat 404, and a gear 406 and a worm gear 407 are fixedly connected to the outside of the second rotating shaft 405. The gear 406 and... The teeth on the top of the toothed plate 403 mesh with each other. A worm 408 is rotatably connected inside the rotating seat 404, and the worm 408 meshes with the worm wheel 407. An adjusting handwheel 409 is fixedly connected to one end of the worm 408 located outside the rotating seat 404. By rotating the adjusting handwheel 409, the worm 408 is driven to rotate, thereby driving the gear 406 to rotate. Then, with the cooperation of the toothed plate 403, the rotating seat 404 can be rotated, thereby adjusting the angle between the adjustable column 300 and the ground, so that the device can be erected on the sloping ground.

[0036] Specifically, a scale 412 is fixedly connected to both sides of the base 401, and a pointer 413 is fixedly connected to both ends of the first rotating shaft 402. The two pointers 413 correspond to the two scales 412 respectively. The angle of rotation of the rotating seat 404 can be easily read through the cooperation of the pointers 413 and the scales 412.

[0037] Furthermore, a bottom cover 410 is fixedly connected inside the base 401, and an upper cover 411 is fixedly connected to both sides of the rotating seat 404. The top of the bottom cover 410 is arc-shaped, and both upper covers 411 are movably sleeved on the outside of the bottom cover 410. The upper covers 411 and the bottom cover 410 can prevent debris from entering the interior of the rotating seat 404.

[0038] The operation process of this embodiment is as follows: When it is necessary to adjust the installation angle of the surveying instrument, firstly, the worm gear 408 is rotated by rotating the adjustment handwheel 409, and then the worm gear 408 drives the worm wheel 407 to rotate. After that, the worm wheel 407 drives the gear 406 to roll on the top of the gear plate 403 through the second rotating shaft 405, so that the rotating seat 404 can rotate. In this way, the installation angle of the surveying instrument can be adjusted on the inclined ground, making the adjustment of the surveying instrument more convenient.

[0039] Example 3 Please see Figure 3 Based on specific embodiments one and two, the adjustable column 300 includes a frame 301. A first threaded sleeve 303 is rotatably connected to the top of the frame 301. A first screw 302 is threaded inside the first threaded sleeve 303. A slider 305 is fixedly connected to the bottom of the first screw 302 and is slidably connected inside the frame 301. A surveying instrument mounting base 600 is fixedly connected to the top of the first screw 302. A first handwheel 304 is fixedly connected to the outside of the first threaded sleeve 303. By rotating the first handwheel 304, the first threaded sleeve 303 can be rotated. Subsequently, under the action of the thread, the first screw 302 can be moved up and down, thereby adjusting the height of the surveying instrument.

[0040] The operation process of this embodiment is as follows: When it is necessary to adjust the height of the surveying instrument, the first handwheel 304 can be rotated to drive the first threaded sleeve 303 to rotate. Then, under the action of the thread, the first screw 302 and the slider 305 can move up and down, thereby adjusting the height of the surveying instrument and making it more convenient for surveyors of different heights to use.
