Description

[0002] The surveying and mapping instrument is an essential instrument in engineering construction, which includes various orientation, distance measurement, angle measurement, height measurement, mapping and photogrammetry required for measurement work in the planning, design, construction and management stages of engineering construction.

[0003] The surveying and mapping instrument is generally used with a positioning seat when used, and the bottom of the positioning seat is supported by a tripod to form a workbench, so as to support the surveying and mapping instrument. Some positioning seats are also provided with leveling mechanisms, rotating mechanisms and the like, so as to facilitate surveying and mapping operation.

[0004] The rotating mechanism is driven to rotate by a small gear driving a large gear, so as to realize manual precise control of the rotation of the surveying and mapping instrument and ensure the accuracy of surveying and mapping. The design principle has an unavoidable contradiction that "the higher the accuracy, the slower the adjustment" (the smaller the transmission ratio of the small gear and the large gear, the higher the controllable accuracy), so that the high-precision rotating mechanism is very time-consuming to use. Therefore, the present application provides a surveying and mapping instrument positioning device and a positioning method thereof with high precision and fast operation. SUMMARY

[0048] The present invention also provides a positioning method for a surveying instrument positioning device, which, using the aforementioned surveying instrument positioning device, includes the following steps:

[0049] S1. Adjust the height of the three sets of leveling feet appropriately to ensure that the top platform and the surveying instrument mounting base are in a horizontal state;

[0050] S2. Press down on the button cover. The first gear overcomes the elastic support of the first spring, causing the first gear and the locking disc to slide down synchronously. The hook at the bottom of the locking disc engages with the card plate and rotates the surveying instrument synchronously in the first direction, causing the surveying instrument mounting base to rotate accordingly. The gear ring assembly drives the first gear to rotate, and under the action of the elastic telescopic component and the ball assembly, it drives the locking disc to rotate, causing the hook to rotate in the first direction and press against the partition plate, releasing the button cover. Then, manipulate the surveying instrument to rotate in a large angle along the first direction, and after reaching the appropriate position, manipulate the surveying instrument to rotate in the second direction. Then, use the manual drive component to drive the surveying instrument for fine-tuning.

[0051] This invention provides a mapping instrument positioning device and its positioning method. It has the following beneficial effects:

[0052] 1. This invention improves the rotation adjustment mechanism, enabling large-angle adjustments from the surveying instrument mounting base to adjust the surveying instrument to a predetermined angle (coarse adjustment), and also allowing small-angle adjustments from the manual drive end to fine-tune the surveying instrument. This achieves high-precision adjustment requirements and efficiently adjusts the surveying instrument's angle. In practical applications, this reduces the workload of surveyors adjusting the surveying instrument's rotation, improves surveying efficiency, and accelerates project progress.

[0053] 2. This invention, through the design of a base platform, top platform, and leveling feet structure, utilizes the base platform to support the ground and relies on three sets of leveling feet to adjust the level of the top platform. This facilitates the adjustment of the top platform and the surveying instrument mounting base to a horizontal state. Furthermore, the rotating sleeves on the leveling feet can slide upwards, and the tilting spring assembly maintains the position of the rotating sleeves, separating them from the transmission between them and the bottom screw. This avoids accidentally touching the rotating sleeves after leveling, which would affect the levelness of the top platform. This structural design can increase the accuracy of surveying and avoid the problem of surveying failure (changing the position of the surveying instrument during the surveying of a set of related data will cause surveying failure and require re-surveying).

[0076] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0077] Example 1:

[0078] like Figures 1-21 As shown, this embodiment of the invention provides a surveying instrument positioning device, including a base 1, a bottom platform 2, a top platform 5, leveling legs 3, a surveying instrument mounting base 4, and a rotation adjustment mechanism 7.

[0079] The base 1 is used to stably support the ground. The bottom end of the base platform 2 is fixedly fastened to the top of the base 1. The bottom of the base platform 2 is the first platform. The user adjusts the three sets of support frames 105 of the base 1 to make the base platform 2 as level as possible. The top platform 5 is set parallel and spaced above the base platform 2. There are three sets of leveling feet 3. All three sets of leveling feet 3 are installed between the base platform 2 and the top platform 5. By repeatedly adjusting the three sets of leveling feet 3, the leveling top platform 5 can be adjusted to a horizontal state. The level 6 installed on the top of the top platform 5 is used to assist in judging the horizontal state of the top of the top platform 5.

[0080] The top platform 5 includes a second housing 501 and a cover plate 502. The top of the second housing 501 is open, and the cover plate 502 is fixedly installed on the top of the second housing 501, making the interior of the top platform 5 a hollow structure to facilitate the installation of the rotation adjustment mechanism 7. Installing the rotation adjustment mechanism 7 inside the second housing 501 can prevent damage to the rotation adjustment mechanism 7 from the external environment during use and ensure the accuracy of the rotation adjustment mechanism 7. The surveying instrument mounting base 4 is rotatably connected to the cover plate 502, and the rotation adjustment mechanism 7 for driving the rotation of the surveying instrument mounting base 4 is installed on the inner side of the top platform 5. The surveying instrument is fixedly installed on the surveying instrument mounting base 4 so that it is in a horizontal state together with the top platform 5. In actual use, the rotation adjustment mechanism 7 can be used to drive the rotation of the surveying instrument mounting base 4 to adjust the use angle of the surveying instrument.

[0081] Specifically, the rotation adjustment mechanism 7 includes: a drive shaft 701, a first gear 708, a first spring 709, a locking disc 710, a card slot disc 712, and a button cover 711.

[0082] The drive shaft 701 is rotatably connected to the second housing 501 via bearings. The bottom end of the drive shaft 701 is located below the second housing 501 and is equipped with a manual drive component. The manual drive component is a user-friendly component that drives the drive shaft 701 to rotate. The top end of the drive shaft 701 is located inside the second housing 501, and an upper end head 705 is fixedly connected to the top end of the drive shaft 701. The first gear 708 is rotatably mounted on the drive shaft 701 and can slide up and down relative to the drive shaft 701. The top end of the first gear 708 has several slots 707 arranged in a circular array. The bottom of the upper end head 705 is fixedly connected to a locking piece 706 corresponding to the slot 707. When the first gear 708 slides upward to a higher position, the locking piece 706 is inserted into the slot 707. Inside 07, the first gear 708 and the transmission shaft 701 can only rotate synchronously. The transmission shaft 701 can be driven to rotate by a manual drive, which in turn drives the first gear 708 to rotate. The portion of the surveying instrument mounting base 4 located inside the second housing 501 is fixedly equipped with a gear ring assembly 404. The first gear 708 meshes with the gear ring assembly 404, and the first gear 708 drives the gear ring assembly 404 to rotate. The first gear 708 is a small gear structure, and the gear ring assembly 404 is a large gear structure. The rotation between them achieves deceleration. The operator rotates the transmission shaft 701 to control the rotation of the first gear 708, thereby driving the gear ring assembly 404 to rotate at a small angle, achieving precise adjustment of the rotation of the gear ring assembly 404, and driving the surveying instrument mounting base 4 and the surveying instrument mounted on the top of the surveying instrument mounting base 4 to perform precise small-angle adjustments.

[0083] The first spring 709 is sleeved on the drive shaft 701 and located below the first gear 708. The bottom end of the first spring 709 is supported on the inner bottom of the second housing 501, and the top end of the first spring 709 is elastically supported on the bottom end of the first gear 708. The first spring 709 pushes the first gear 708 upward so that when no external force is applied, the first gear 708 is in a higher position (corresponding to the insertion of the clip 706 into the slot 707, and the first gear 708 and the drive shaft 701 can only rotate synchronously).

[0084] The locking disc 710 is sleeved on the drive shaft 701, and the top end of the locking disc 710 is rotatably connected to the bottom end of the first gear 708, allowing the locking disc 710 and the first gear 708 to rotate coaxially, while preventing them from moving axially. The top end of the locking disc 710 has several circular grooves, each containing a rotating ball assembly 713. The rotating ball assembly 713 protrudes slightly above the upper surface of the locking disc 710. The bottom of the first gear 708 has an elastic telescopic member corresponding to the rotating ball assembly 713. The locking disc 710 and the first gear 708 are connected in a specific configuration. When the disc 710 rotates relative to the first gear 708, the bottom end of the elastic telescopic member and the ball assembly 713 push from the side. If the locking disc 710 cannot rotate, during the rotation of the first gear 708, the elastic telescopic member pushes the ball assembly 713 from the side. The elastic telescopic member is compressed and retracts, able to pass over the ball assembly 713, and at the same time, a "click" sound is heard. The first gear 708 and the locking disc 710 rotate relative to each other. If the locking disc 710 is in a free state, the elastic telescopic member pushes the ball assembly 713 from the side. The ball assembly 713 transmits the thrust to the locking disc 710, so that the locking disc 710 and the first gear 708 rotate synchronously.

[0085] The card holder 712 is sleeved on the outside of the drive shaft 701, and the bottom end of the card holder 712 is fixedly connected to the inner bottom of the second housing 501. The bottom end of the locking plate 710 is fixedly connected to the hook 717. The card holder 712 has an annular opening, so that the hook 717 can be flipped down onto the card holder 712. Several partition plates 718 are fixedly connected to the inner side of the card holder 712. The partition plates 718 divide the annular opening of the card holder 712 into several arc-shaped parts. Each arc-shaped part has a notch 719 in the middle area, so that the hook 717 can pass through the notch 719 in the vertical direction. The button cover 711 is slidably connected to the cover plate 502 in the vertical direction, and the bottom end of the button cover 711 is located at the top of the first gear 708.

[0086] like Figure 5 , Figure 6In the indicated state, the bottom end of the locking disc 710 is fixedly connected to a hook 717 but is not connected to the annular opening on the mounting plate 712. Under the action of the first spring 709, both the first gear 708 and the locking disc 710 are in a high position, and the clip 706 is inserted into the slot 707. The first gear 708 and the drive shaft 701 can only rotate synchronously. In this state, the user can manually drive the drive shaft 701 to rotate, which in turn drives the first gear 708 to rotate. The first gear 708 drives the gear ring assembly 404 to rotate, allowing for adjustment of the plotter installation. The base 4 rotates; at this time, the user operates the button cover 711 (presses the button cover 711), the button cover 711 pushes the first gear 708 and the transmission shaft 701 downward, overcoming the elastic support of the first spring 709, so that the first gear 708 and the transmission shaft 701 slide downward synchronously, so that the hook 717 is hooked upside down on a certain arc-shaped part (one part of the annular opening). The user simultaneously operates the surveying instrument to rotate in the first direction, the surveying instrument and the surveying instrument mounting base 4 rotate, the gear ring assembly 404 rotates, driving the first gear 708 meshed with it to rotate, the first gear 708 Push the locking disc 710 to rotate in the first direction, so that the hook 717 is located on one side of the notch 719 in the arc-shaped part in the first direction. Then, the user can release the button cover 711 and adjust the plotter to rotate at a large angle with both hands. At this time, the plotter mounting base 4 rotates, the gear ring assembly 404 rotates, and drives the first gear 708 that meshes with it to rotate. The first gear 708 is in a disengaged state from the drive shaft 701 and will not drive the drive shaft 701 to rotate, so that the user can make adjustments quickly. Generally, the adjustment is slightly beyond the predetermined first direction rotation. The position is adjusted, and then the surveying instrument is rotated in the second direction (one of the first direction and the second direction is clockwise, and the other is counterclockwise). The surveying instrument, together with the surveying instrument mounting base 4, rotates, and the gear ring assembly 404 rotates, driving the first gear 708 that meshes with it to rotate. The first gear 708 rotates in the second direction, pushing the locking disc 710 to rotate in the second direction. When the hook 717 passes through the notch 719, under the elastic support of the first spring 709, the locking disc 710 and the first gear 708 return to their original positions, and the angle can be finely adjusted.

[0087] In one embodiment, the base 1 includes: a retaining plate 101, a support frame 105, and a counterweight 106; wherein, a support member 102 is fixedly connected to the top of the retaining plate 101, the support member 102 is used to support the top of the first housing 201, a tray 103 is fixedly connected to the bottom of the retaining plate 101, the tray 103 is thicker and is the main support part, a hinge member 104 is fixedly connected to the top of the support frame 105, the hinge member 104 is hinged to the tray 103, the support frame 105 is provided in three sets and is distributed in a triangular shape to facilitate unfolding to form a tripod, and the counterweight 106 is fixedly connected to the bottom center position of the tray 103 to improve the stability of the base 1.

[0088] In one embodiment, the base 2 includes: a first housing 201, a slider 203, a leaf spring 205, and a T-shaped tool 206 used in conjunction with it.

[0089] The first housing 201 has an opening at its bottom, allowing the retaining plate 101 to be inserted into the inside of the first housing 201. A sliding opening 202 is provided on the side of the first housing 201, and a sliding member 203 is slidably connected to the sliding opening 202. The lower part of the sliding member 203 located inside the first housing 201 is provided with barbed teeth 204. When the retaining plate 101 is inserted into the inside of the first housing 201, the barbed teeth 204 engage with the side of the retaining plate 101, achieving a fixed connection between the two. The upper part of the sliding member 203 located inside the first housing 201 is provided with an inclined mounting surface. The first end of the folding spring 205 is fixedly connected to the inner wall of the first housing 201, and the second end of the folding spring 205 is fixedly connected to the inclined mounting surface. The folding spring 205 causes the sliding member 203 to slide towards the inside of the first housing 201.

[0090] When disassembling the card plate 101, connect one end of the T-shaped tool 206 to the side of the slider 203 facing the outside of the first housing 201 with a thread. Use the T-shaped tool 206 to pull the slider 203 outward to overcome the elastic force of the leaf spring 205, so that the slider 203 slides outward. At this time, the card plate 101 can be disassembled.

[0091] In one embodiment, the leveling support 3 includes: a bottom screw 301, a bottom inverted spring plate 304, a top screw 306, a top inverted spring plate 309, a spindle 3011, a transmission component 3014, a rotating wheel sleeve 3016, and a tilting spring assembly 3018.

[0092] The bottom nut 303 is fixedly installed on the inner top of the first housing 201. The bottom screw 301 is threadedly connected to the bottom screw 301. By rotating the bottom screw 301, the bottom screw 301 moves up and down to adjust the overall height of the support leg 3 (the height between the first platform and the top). The top of the bottom screw 301 has a first circular groove 302. The bottom end of the bottom screw 301 is fixedly connected to a first thin shaft. The bottom inverted spring plate 304 is sleeved on the first thin shaft. The bottom inverted spring plate 304 is connected to the first thin shaft by the first pressure plate nut 305 threaded on the first thin shaft. The inclined support of the bottom inverted spring plate 304 abuts against the inner top of the first housing 201. The elastic force generated by the inclined support of the bottom inverted spring plate 304 keeps the bottom nut 303 and the bottom screw 301 under stress, thereby avoiding the gap between the threads from causing slight shaking between them.

[0093] A top nut 308 is fixedly installed at the inner bottom of the second housing 501. A top screw 306 is threadedly connected to the top nut 308. A top circular groove 307 is opened at the bottom end of the top screw 306. A second thin shaft is fixedly connected to the top end of the top screw 306. A top inverted spring plate 309 is sleeved on the second thin shaft. The top inverted spring plate 309 is connected to the second thin shaft by a second pressure plate nut 3010 threaded on the second thin shaft. The inclined support of the top inverted spring plate 309 abuts against the inner bottom of the second housing 501.

[0094] The top end of the mandrel 3011 is interference-fitted with the top circular groove 307, and the bottom end of the mandrel 3011 is fixedly connected with an end ring. The bottom end of the mandrel 3011 is rotatably mounted on the inner side of the first circular groove 302 by means of a limiting copper sleeve 3012 sleeved on the outside of the mandrel 3011 and interference-fitted with the first circular groove 302. The middle section of the mandrel 3011 has an elastic section, which allows the mandrel 3011 to bend slightly.

[0095] The transmission component 3014 is slidably sleeved on the spindle component 3011, and the bottom end of the transmission component 3014 is the first friction surface, the top end of the bottom screw 301 is the friction end surface 3013, the top end of the transmission component 3014 has a hexagonal portion 3015, the rotating wheel sleeve 3016 is sleeved on the outside of the bottom screw 301 and the top screw 306, and an inner hexagonal ring 3017 is fixedly connected on the inner side of the rotating wheel sleeve 3016 and located between the bottom screw 301 and the top screw 306. The inner hexagonal ring 3017 corresponds to the hexagonal portion 3015. One end of the tilting spring assembly 3018 is fixedly connected to the spindle component 3011, and the other end of the tilting spring assembly 3018 is slidably mounted on the upper end surface of the inner hexagonal ring 3017.

[0096] like Figure 10 In the indicated state, the tilting spring assembly 3018 is curved downwards, and the elastic force it generates pushes the rotating sleeve 3016 downwards, causing the inner hexagonal ring 3017 to be fitted onto the hexagonal portion 3015. This allows the rotating sleeve 3016 and the transmission component 3014 to rotate synchronously. Furthermore, the elastic force generated by the tilting spring assembly 3018 pushes the rotating sleeve 3016 and the transmission component 3014 downwards. The bottom end of the transmission component 3014 presses against the friction end face 3013 at the top of the bottom screw 301, enabling the bottom screw 301 to rotate and adjust the length of the leveling foot 3. After leveling is completed, the user slides the rotating sleeve 3016 upwards. After the tilting spring assembly 3018 passes the horizontal state, it is in an upwardly curved state. The elastic force it generates pushes the rotating sleeve 3016 upwards, causing the rotating sleeve 3016 to separate from the transmission component 3014. At this time, accidentally touching the rotating sleeve 3016 will not cause a change in the length of the leveling foot 3.

[0097] Specifically, such as Figure 12As shown, the tilting spring assembly 3018 includes: a first arc-shaped spring 301801 and a second arc-shaped spring 301802. The first end of the first arc-shaped spring 301801 is fixedly connected to the first end of the second arc-shaped spring 301802, and the first ends of the first arc-shaped spring 301801 and the second arc-shaped spring 301802 are both fixedly connected to the side of the spindle 3011. The second ends of the first arc-shaped spring 301801 and the second ends of the second arc-shaped spring 301802 are both provided with sliding holes, and mounting pins 301804 that are fixedly connected to the upper end face of the internal hexagonal ring 3017 are provided in the sliding holes. A rubber pad 301803 is provided between the second ends of the first arc-shaped spring 301801 and the second ends of the second arc-shaped spring 301802.

[0098] The rubber pad 301803 makes the first arc spring 301801 and the second arc spring 301802 more deformable, making it easier to cross the horizontal state and change from an upward arc bend to a downward arc bend (or from a downward arc bend to an upward arc bend).

[0099] In one embodiment, the surveyor mounting base 4 includes: a rotating column 401, with a mounting flange 402 fixedly connected to the top of the rotating column 401 for fixed installation with the surveyor, and a mounting nut 403 threadedly connected to the bottom of the rotating column 401 and below the gear ring assembly 404. The rotating column 401 is provided with a step portion that restricts the upward sliding of the gear ring assembly 404, and the gear ring assembly 404 is clamped and fixed by the mounting nut 403 and the step portion.

[0100] In one embodiment, the top of the gear ring assembly 404 is provided with an arc-shaped opening 405, the central angle corresponding to the arc-shaped opening 405 is 120°-180°, and the button cover 711 slides inside the arc-shaped opening 405.

[0101] In one embodiment, the manual drive includes a turbine 702, a worm gear 703, and a protective housing 704.

[0102] The turbine 702 is fixedly connected to the drive shaft 701, and the worm 703 is rotatably mounted to the bottom of the second housing 501. The worm 703 meshes with the turbine 702, and a knob is fixedly connected to one end of the worm 703. The user operates the knob to drive the worm 703 to rotate, which in turn drives the turbine 702 to rotate, causing the drive shaft 701 to rotate.

[0103] The protective housing 704 is fixedly installed at the bottom of the second housing 501, and covers the turbine 702 and worm 703 for protection. In some cases, lubricating oil is also provided inside the protective housing 704.

[0104] In one embodiment, the elastic telescopic member includes: a mounting groove 714 opened at the bottom of the first gear 708, a rubber block 716 fixedly connected to the inner side of the mounting groove 714, a limiting member 715 fixedly connected to the bottom of the rubber block 716, and both sides of the bottom of the limiting member 715 being inclined surfaces, so that it can easily pass over the ball assembly 713.

[0105] In one embodiment, a first rotating connection portion 7081 is fixedly connected to the bottom of the first gear 708, and a second rotating connection portion 71001 is fixedly connected to the top of the locking disc 710. The first rotating connection portion 7081 and the second rotating connection portion 71001 are rotatably connected.

[0106] Example 2

[0107] A positioning method for a surveying instrument positioning device, using the surveying instrument positioning device in Embodiment 1, includes the following steps:

[0108] S1. Adjust the height of the three sets of leveling feet 3 appropriately so that the top platform 5 and the surveying instrument mounting base 4 are in a horizontal state, so that the surveying instrument can be used normally.

[0109] S2. When rotational mapping is required, press down on the button cover 711. The first gear 708 overcomes the elastic support of the first spring 709, causing the first gear 708 and the locking plate 710 to slide down synchronously. The hook 717 at the bottom of the locking plate 710 engages with the card plate 712 and rotates the mapping instrument synchronously in the first direction, causing the mapping instrument mounting base 4 to rotate accordingly. The gear ring assembly 404 drives the first gear 708 to rotate, and under the action of the elastic telescopic component and the ball assembly 713, it drives the locking plate 710 to rotate, causing the hook 717 to rotate in the first direction and press against the partition plate 718, releasing the button cover 711. Then, operate the mapping instrument at a large angle to rotate along the first direction, and after reaching the appropriate position, operate the mapping instrument to rotate in the second direction. Then, use the manual drive component to drive the mapping instrument for fine adjustment.
