Description

Technical Field

[0001] The present invention relates to the field of surveying and mapping technology, and particularly to a on-site surveying and mapping device for construction projects. Background Art

[0002] Surveying and mapping instruments, simply speaking, are instruments and devices designed and manufactured for surveying and mapping operations, such as various instruments for orientation, distance measurement, angle measurement, height measurement, mapping, and photogrammetry required for surveying work in the planning, design, construction, and operation management stages of engineering construction, and instruments for measuring the elevation difference between two points.

[0003] Chinese Patent with publication number "CN219473204U" discloses a on-site surveying and mapping device, and its technical solution is: under the action of a lifting assembly, the height of the surveying instrument can be finely adjusted, facilitating the surveying instrument to be adjusted to a more appropriate height for surveying and mapping use. According to the specific use environment, a suitable support mechanism can be selected to support on the ground, making the overall device more widely applicable.

[0004] However, after using this device, the staff needs to fold up and carry the support legs and support feet. However, the above device requires manual storage of its support legs and cannot automatically store the support feet and support legs, which affects the work efficiency of surveying personnel and increases the work intensity of the staff. And after using this device, the level needs to be stored and protected, but the device cannot protect the level and directly exposes the level to the outside. Therefore, when carrying this device, the level is easily bumped by the outside, which easily causes damage to the level and loosening of internal components, thus shortening the service life of the level and reducing the measurement effect. Summary of the Invention The purpose of the present invention is to solve the deficiencies existing in the prior art. After using this device, the staff needs to fold up and carry the support legs and support feet. However, the above device requires manual storage of its support legs and cannot automatically store the support feet and support legs, which affects the work efficiency of surveying personnel and increases the work intensity of the staff. In addition, after using this device, the level needs to be stored and protected, but this device cannot protect the level and directly exposes the level to the outside.

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] As Figures 1-9 shown, the present invention provides a technical solution: a on-site surveying and mapping device for construction engineering, including a support platform 1, a protection box 2, a level 4, a lifting protection mechanism 8, a storage mechanism 3 and a support mechanism 9; the protection box 2 is fixedly connected to the top of the support platform 1; the level 4 is arranged at the top of the lifting protection mechanism 8; the lifting protection mechanism 8 is arranged inside the protection box 2, and the lifting protection mechanism 8 includes a linking rod 801, a threaded rod 804 and a threaded block 805, and the top of the threaded rod 804 is rotationally connected to the inside of the threaded block 805 through threads; the storage mechanism 3 is arranged at the bottom of the lifting protection mechanism 8, and the storage mechanism 3 includes a telescopic rod 303 and a storage rod 304; the support mechanism 9 is arranged at the bottom of the support platform 1, and the support mechanism 9 includes a rotating plate 901, a main pin column 902 and a main pin thorn 903; the bottom of the support platform 1 is rotatably connected with a plurality of support frames 10 through a rotating shaft, and the plurality of support frames 10 are symmetrically distributed around the center of the support platform 1, and a storage groove 11 is opened at the bottom of the support frame 10; the support mechanism 9 is rotatably connected to the bottom of the support frame 10 through a rotating shaft.

[0031] First, when the device needs to be carried, the support frame 10 and the level 4 need to be retracted and protected respectively. At this time, the lifting and protecting mechanism 8 is started by running the servo motor 15. At this time, the lifting and protecting mechanism 8 lowers the level 4 into the protection box 2 for protection. At the same time, the lifting and protecting mechanism 8 drives the bevel gear three 13 to rotate. Since the bevel gear three 13 meshes with the bevel gear four 14, the bevel gear four 14 drives the receiving mechanism 3 to move. Thus, the receiving mechanism 3 drives the support frame 10 to be retracted, which is beneficial to retract the support frame 10 by operating the receiving mechanism 3, so as to achieve the effect of automatic storage and facilitate the staff to carry. While the receiving mechanism 3 retracts the support frame 10, the support frame 10 retracts the retractable rod 17, so that the whole mechanism has integrity and linkage. Thus, the retractable rod 17 is received inside the receiving groove 11. Finally, when the device needs to be carried, the handle 27 is pulled outward at this time, so that the handle 27 drives the limiting rod 23 to move outward. At this time, the limiting rod 23 drives the limiting plate 24 to move outward. At the same time, the spring 26 expands and contracts inside the movable groove 25. Furthermore, the limiting rod 23 leaves the inside of the limiting groove 22. Then, by pushing the pull rod 5 downward, the pull rod 5 drives the moving block 904 to move downward at this time, so that the supporting mechanism 9 moves downward. Then, the limiting rod 23 is inserted into the inside of another limiting groove 22, so as to limit the supporting mechanism 9. Thus, the supporting mechanism 9 is attached to the ground for movement.

[0032] As Figure 1 and Figure 6 shown, the lifting and protecting mechanism 8 further includes a bevel gear one 802 and a bevel gear two 803; both ends of the linkage rod 801 are fixedly connected to the inside of two bevel gears one 802 respectively. The bevel gear one 802 meshes with the bevel gear two 803, and the inside of the bevel gear two 803 is fixedly connected to the outer wall of the threaded rod 804; the threaded block 805 is L-shaped, and the top end of the threaded block 805 is fixedly connected with a mounting block 12. The bottom end of the level 4 is closely attached to the top end of the mounting block 12; one end of the threaded block 805 is slidably connected to the inner wall of the protection box 2; the middle position of the linkage rod 801 is fixedly connected with a bevel gear three 13, and a bevel gear four 14 is arranged below the linkage rod 801. The bevel gear three 13 meshes with the bevel gear four 14; the bottom end of the threaded rod 804 is fixedly connected with a servo motor 15, and the bottom end of the servo motor 15 is fixedly connected to the inner top end of the support table 1.

[0033] By starting the servo motor 15, the servo motor 15 drives the bevel gear II 803 to rotate through the threaded rod 804. Since the bevel gear II 803 meshes with the bevel gear I 802, the bevel gear I 802 drives the linkage rod 801 to rotate. At this time, the linkage rod 801 drives another bevel gear I 802 to rotate. Since another bevel gear I 802 meshes with another bevel gear II 803, another bevel gear II 803 drives another threaded rod 804 to rotate. At this time, the two threaded rods 804 drive the threaded block 805 to move up and down, so that the threaded block 805 drives the mounting block 12 to move up and down. Thus, the mounting block 12 drives the level 4 to move up and down inside the protection box 2. It is beneficial to push the threaded block 805 to drive the level 4 to rise for use when using the level 4. After use, the threaded block 805 will be lowered to drive the level 4 into the protection box 2 for safety protection. After the level 4 is retracted into the protection box 2, at the same time, the linkage rod 801 drives the bevel gear III 13 to rotate. Since the bevel gear III 13 meshes with the bevel gear IV 14, the bevel gear IV 14 drives the storage mechanism 3 to move synchronously. Thus, the storage mechanism 3 retracts the support frame 10. It is beneficial to simultaneously protect the level 4 into the protection box 2 and retract the support frame 10 by controlling the servo motor 15, so that the whole structure has linkage and integrity.

[0034] As Figure 1 , Figure 2 and Figure 5 shown, the storage mechanism 3 further includes a worm 301 and a worm gear 302. The worm 301 meshes with a plurality of worm gears 302, and one end of the telescopic rod 303 and the storage rod 304 is respectively movably connected to the inside of the worm gear 302 through a rotating shaft; the top end of the worm 301 penetrates through the inside of the support platform 1 and extends into the protection box 2, and the top end of the worm 301 is fixedly connected to the inside of the bevel gear IV 14. The top end of the telescopic rod 303 is fixedly connected to the bottom end of the support platform 1; one end of the storage rod 304 away from the worm gear 302 is movably connected to one side of the support frame 10 through a rotating shaft, and the bottom end of the worm 301 is movably connected to a fixed column 16; a plurality of retractable rods 17 are movably connected to the outer wall of the fixed column 16 through a rotating shaft, and one end of the retractable rod 17 is movably connected to the inside of the storage groove 11 through a rotating shaft; the bottom end of the fixed column 16 is fixedly connected to a disc 18, and a plurality of support blocks 19 are fixedly connected to the outer wall of the disc 18. A secondary pin column 20 is fixedly connected to the bottom end inside the support block 19, and a secondary pin thorn 21 is fixedly connected to the outer wall of the secondary pin column 20. The secondary pin column 20 and the secondary pin thorn 21 are both located below the disc 18; the top end of the secondary pin thorn 21 is fixedly connected to a slider 6, and a lifting rod 7 is rotatably connected to the inside of the slider 6 through a thread. The outer wall of the lifting rod 7 is movably connected to the inside of the support block 19.

[0035] When the support frame 10 needs to be stored, the lifting and protecting mechanism 8 is driven by the servo motor 15 to move. At the same time, the lifting and protecting mechanism 8 drives the third bevel gear 13 to rotate. Since the third bevel gear 13 meshes with the fourth bevel gear 14, the fourth bevel gear 14 drives the worm 301 to rotate. Since the worm 301 meshes with a plurality of worm wheels 302, the worm 301 drives the worm wheels 302 to move downward. At this time, the worm wheels 302 drive the telescopic rods 303 to extend downward, and at the same time, the worm wheels 302 drive the storage rods 304 to rotate at an angle, so that the storage rods 304 drive the support frame 10 to contract. It is beneficial to contract the support frame 10 by operating the worm 301 through the storage rod 304, so as to achieve the effect of automatic storage and facilitate the staff to carry. While the storage rod 304 stores the support frame 10, the support frame 10 gathers the contraction rod 17, so that the contraction rod 17 is stored inside the storage groove 11. At the same time, the staff rotates the lifting rod 7 upward. At this time, the lifting rod 7 drives the slider 6 to move upward inside the support block 19, so that the slider 6 drives the auxiliary pin 20 and the auxiliary pin thorn 21 to move upward, so that the auxiliary pin 20 and the auxiliary pin thorn 21 leave the ground, thus avoiding damage to the auxiliary pin 20 and the auxiliary pin thorn 21 during transportation.

[0036] As Figure 1 、 Figure 7 and Figure 8 shown, the support mechanism 9 further includes a moving block 904 and moving wheels 905; the bottom end of the rotating plate 901 is fixedly connected to the top end of the main pin 902, and one end of the outer wall of the main pin 902 is fixedly connected to a plurality of main pin thorns 903; both ends of the moving block 904 are slidably connected to the inner wall of the rotating plate 901, and the bottom end of the moving block 904 is fixedly connected to the top end of the moving wheel 905; a plurality of limiting grooves 22 are formed inside the moving block 904, and a limiting rod 23 is movably connected inside the limiting grooves 22, and a limiting plate 24 is fixedly connected to the outer wall of the limiting rod 23; movable grooves 25 are formed on both sides of the rotating plate 901, and a spring 26 is fixedly connected inside the movable grooves 25, and the spring 26 is located on the opposite side of the limiting plate 24 and the rotating plate 901; one end of the limiting rod 23 away from the moving block 904 is fixedly connected to a pulling handle 27, and the pulling handle 27 is located outside the rotating plate 901; the top end of the moving block 904 is fixedly connected to a pulling rod 5, and the pulling rod 5 is located on the top end of the rotating plate 901.

[0037] When the device needs to be carried, pull the handle 27 outward at this time, so that the handle 27 drives the limit rod 23 to move outward. At this time, the limit rod 23 drives the limit plate 24 to move outward. At the same time, the spring 26 performs telescopic movement inside the movable groove 25. Furthermore, the limit rod 23 leaves the inside of the limit groove 22. Then, by pushing the pull rod 5 downward, at this time the pull rod 5 drives the moving block 904 to move downward, so that the moving block 904 drives the moving wheel 905 to move downward. Then, the limit rod 23 is inserted into the inside of another limit groove 22, thereby limiting the moving wheel 905. At this time, the height of the moving wheel 905 is higher than the kingpin 902, so that the moving wheel 905 is in contact with the ground.

[0038] Working principle: First, when the device needs to be carried, the servo motor 15 drives the threaded rod 804 to rotate, so that the threaded rod 804 drives the bevel gear two 803 to rotate. Since the bevel gear two 803 meshes with the bevel gear one 802, at this time, the bevel gear two 803 drives the bevel gear one 802 to rotate, and then the bevel gear one 802 drives the linkage rod 801 to rotate. At this time, the linkage rod 801 drives the bevel gear three 13 to rotate. Since the bevel gear three 13 meshes with the bevel gear four 14, the bevel gear four 14 drives the worm 301 to rotate. Since the worm 301 meshes with multiple worm wheels 302, the worm 301 drives the worm wheel 302 to move downward. At this time, the worm wheel 302 drives the telescopic rod 303 to extend downward, and at the same time, the worm wheel 302 drives the storage rod 304 to rotate at an angle, so that the storage rod 304 drives the support frame 10 to contract. Then, while the storage rod 304 stores the support frame 10, the support frame 10 folds back the contraction rod 17, so that the contraction rod 17 is stored inside the storage groove 11. At the same time, the staff rotates the lifting rod 7 upward, and at this time, the lifting rod 7 drives the slider 6 to move upward inside the support block 19, so that the slider 6 drives the auxiliary pin column 20 and the auxiliary pin thorn 21 to move upward, so that the auxiliary pin column 20 and the auxiliary pin thorn 21 leave the ground, and then protect the auxiliary pin column 20 and the auxiliary pin thorn 21 during the carrying process. Secondly, while starting the servo motor 15, the servo motor 15 drives the bevel gear two 803 to rotate through the threaded rod 804. Since the bevel gear two 803 meshes with the bevel gear one 802, the bevel gear one 802 drives the linkage rod 801 to rotate. At this time, the linkage rod 801 drives another bevel gear one 802 to rotate. Since another bevel gear one 802 meshes with another bevel gear two 803, another bevel gear two 803 drives another threaded rod 804 to rotate. At this time, the two threaded rods 804 drive the threaded block 805 to move up and down, so that the threaded block 805 drives the mounting block 12 to move up and down, so that the mounting block 12 drives the level 4 to move up and down inside the protective box 2. Finally, when the device needs to be moved, at this time, pull the handle 27 outward, so that the handle 27 drives the limiting rod 23 to move outward. At this time, the limiting rod 23 drives the limiting plate 24 to move outward, and at the same time, the spring 26 expands and contracts inside the movable groove 25. Then, the limiting rod 23 leaves the inside of the limiting groove 22. The limiting grooves 22 are arranged vertically. Then, by pushing the pull rod 5 downward, at this time, the pull rod 5 drives the moving block 904 to move downward, so that the moving block 904 drives the moving wheel 905 to move downward. Then, insert the limiting rod 23 into the lower limiting groove 22 to limit the moving wheel 905. At this time, the height of the moving wheel 905 is higher than the main pin column 902, so that the moving wheel 905 is attached to the ground for movement.

[0039] The above are only the preferred embodiments of the present invention, and do not limit the present invention in other forms. Any person skilled in the art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
