Description

Technical Field

[0001] The utility model relates to the technical field of surveying and mapping equipment, in particular to a high-stability surveying and mapping device. Background Art

[0002] Most of the surveying and mapping devices in the prior art are suitable for flat land and have poor applicability. In complex geographical environments, the stability of the surveying and mapping devices is poor, which can easily affect the accuracy of the measurement data during the surveying and mapping process.

[0003] The existing patent authorization number is: CN210739795U, which discloses a high-stability surveying and mapping device, including an outer cylinder, a support foot and a surveying and mapping instrument that are evenly hinged to the lower end of the outer wall of the outer cylinder along the circumference, and a longitudinal opening is symmetrically opened on the side wall of the outer cylinder. Two groups of fixed columns are fixed at the upper and lower ends of the front side wall of the outer cylinder respectively, and a sliding sleeve that can be clamped and fixed with the fixed column is sleeved on the outer side of the outer cylinder. The lower end of the outer cylinder is plugged with an inner cylinder, and the side wall of the inner cylinder is symmetrically connected with two groups of connecting blocks, which pass through the longitudinal openings on both sides of the outer cylinder and are fixedly connected to the inner wall of the sliding sleeve. The bottom is fixedly connected with a bottom plate; the utility model has a novel design and strong applicability. The surveying and mapping device is not only applicable to complex and uneven terrain, but also easy to adjust in height to meet the use needs of different users; after analyzing the device, it is found that it mainly adapts to different surveying and mapping environments by adjusting the length of the support rod. Although it improves the stability during surveying and mapping to a certain extent, due to the use of a unified contact structure with the ground, when encountering soil ground, rugged ground, cement ground, etc., it is impossible to place it optimally according to the different contact grounds, and it is very easy to slide, tilt and other problems;

[0004] Therefore, in view of the above-mentioned problems, the present application proposes a new technical solution. Utility Model Content

The surveying and mapping height of the surveying and mapping instrument is adjusted by lifting and lowering the electric telescopic rod, and the length of each group of support frames is adjusted. According to different surveying and mapping grounds, the surveying and mapping instrument is kept at a horizontal placement angle, that is, the stability of the device is increased. The conversion support member has a variety of conversion forms, and the optimal support structure can be selected according to different grounds to ensure that it can be fully and stably contacted with the ground, and it can also be quickly transferred according to the movement requirements;

The contact between the structures of the outer ends of different mounting blocks and the ground is adjusted by rotating the conversion disk, so that when the surveying instrument is placed in different environments for surveying and mapping, the stability of the bottom can be guaranteed.

[0008] Compared with the prior art, the beneficial effects of the utility model are as follows: by arranging a convertible support at the bottom of the supporting base plate, and utilizing the convertible moving wheels, implantation positioning rods, positioning suction cups, and friction placement plates in the convertible support, the applicable scope of the supporting base plate support is increased, and the maneuverability of the surveying instrument is improved, thereby providing sufficient adaptability for the high-stability surveying and mapping of the surveying instrument.

[0017] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0018] See also Figure 1-Figure 3The high-stability surveying and mapping device comprises a surveying and mapping instrument 10, an electric telescopic rod 11, and a support frame 12; the surveying and mapping instrument 10 is installed on the top of the electric telescopic rod 11, and a plurality of support frames 12 are installed on the lower side wall of the electric telescopic rod 11 in an annular manner at equal intervals and swinging outwards, and the bottom end of the support frame 12 is swingingly connected to a support base plate 13, and a conversion support member 14 is installed at the bottom of the support base plate 13. The surveying and mapping height of the surveying and mapping instrument 10 is adjusted by lifting and lowering the electric telescopic rod 11, and the length of each group of support frames 12 is adjusted. According to different surveying and mapping grounds, the surveying and mapping instrument 10 is kept at a horizontal placement angle, that is, the stability of the device is increased. The conversion support member 14 has a variety of conversion forms, which can select the best support structure according to different grounds to ensure that it can be in full and stable contact with the ground, and can also be quickly transferred according to the movement requirements;

[0019] The conversion support 14 includes a conversion disk 16 rotatably arranged in the middle of the lower part of the support base plate 13, a wheel axle 22 is installed at the center of the conversion disk 16, and wheel frames 15 with the top fixed on the bottom wall of the support base plate 13 are rotatably mounted on both ends of the wheel axle 22. A plurality of mounting blocks 17 are annularly installed on the circumferential outer wall of the conversion disk 16, and the outer walls of the plurality of mounting blocks 17 are respectively rotatably connected to moving wheels 18 through wheel rods, directly installed with cutting positioning rods 19, installed with positioning suction cups 20 through connecting rods, and installed with friction placement plates 21 through connecting rods. By rotating the conversion disk 16, the structures of the outer ends of different mounting blocks 17 are adjusted to contact the ground, so that when the surveying and mapping instrument 10 is placed in different environments for surveying and mapping, the stability of the bottom placement can be guaranteed.

[0020] In the embodiment of the present invention, evenly distributed protrusions are installed on the outside of the friction placement plate 21. Under the action of the protrusions, the contact friction between the outer side of the friction placement plate 21 and the ground is increased, thereby improving the stability of the friction placement plate 21 when placed; the shortest distance between the circumferential outer wall of the conversion plate 16 and the bottom wall of the supporting bottom plate 13 is greater than the distance between the moving wheel 18, the cutting positioning rod 19, the positioning suction cup 20 and the friction placement plate 21 and the circumferential outer wall of the corresponding conversion plate 16, that is, it is ensured that the moving wheel 18, the cutting positioning rod 19, the positioning suction cup 20, and the friction placement plate 21 can smoothly transfer positions under the rotation of the conversion plate 16;

[0021] Specifically, the end of the cutting positioning rod 19 is set to a conical structure to improve the smoothness of the cutting with the ground;

[0022] The type and specific working principle of the surveying instrument 10 will not be elaborated here. Since the focus of the present technical solution is on how to improve the stability of the surveying instrument 10 during use, even if the prior art surveying instrument 10 is not explained and disclosed, it will not affect the integrity of the present technical solution.

[0023] In one embodiment of the present invention, see Figure 4In order to ensure that after each rotation stop of the conversion disk 16, one of the moving wheel 18, the insertion positioning rod 19, the positioning suction cup 20, and the friction placement plate 21 can be accurately transferred to the position directly below the conversion disk 16, that is, to ensure full contact with the ground, a positioning member is provided at one end of the wheel shaft 22, and the positioning member includes four evenly distributed connecting rods 23 installed on the circumferential outer wall of the wheel shaft 22, and a telescopic cylinder 24 is installed at the end of the connecting rod 23. The telescopic cylinder 24 is distributed parallel to the axis of the wheel shaft 22, and the end of the telescopic cylinder 24 facing the wheel frame 15 is set to an open shape, and a positioning pin 25 is telescopically connected inside the telescopic cylinder 24. A limit block 26 is installed at the end of the positioning pin 25 placed inside the telescopic cylinder 24, and the limit block 26 is connected to the telescopic cylinder 24. A spring 27 is elastically connected between the inner walls of the cylinder 24, and a positioning hole is opened at the vertical middle position of the wheel frame 15 corresponding to the end of the positioning pin 25. When the rotating conversion disk 16 drives the wheel shaft 22 to rotate, and the positions of the moving wheel 18, the cutting positioning rod 19, the positioning sucker 20, and the friction placement plate 21 are synchronously adjusted, the four groups of positioning pins 25 are synchronously driven to rotate. Whenever one of the moving wheel 18, the cutting positioning rod 19, the positioning sucker 20, and the friction placement plate 21 moves to the bottom of the conversion disk 16, a corresponding positioning pin 25 is plugged into the positioning hole, thereby ensuring that the moving wheel 18, the cutting positioning rod 19, the positioning sucker 20, and the friction placement plate 21 are accurately adjusted for conversion and use, and remain stable after moving to the desired position;

[0024] Specifically, the end of the positioning pin 25 is configured as an arc-shaped structure to ensure that it can pass smoothly when contacting the edge of the wheel frame 15 .

[0025] The working principle of the utility model is: in the idle position of the device, all the driving parts mentioned above, which refer to the power elements, electrical components and the adapted power supply, are connected through wires, and the electrical connection is completed in a sequential working order between the electrical components. The detailed connection means are well-known technologies in the art. The following mainly introduces the working principle and process, and does not explain the electrical control. When in use, a suitable support structure is selected according to the type of ground to be mapped. When facing a smooth ground, the conversion disk 16 is rotated to move the positioning suction cup 20 to the bottom of the conversion disk 16, and the positioning suction cup 20 is sucked by the ground. Attached positioning, when encountering soil ground, rotate the cutting positioning rod 19 to the bottom of the conversion disk 16, insert the cutting positioning rod 19 into the ground soil, and fix the supporting base plate 13. When encountering a ground other than the above, rotate the friction placement plate 21 to the bottom of the conversion disk 16, and use the friction force of the friction placement plate 21 to improve the stability of the supporting base plate 13. When moving is required, move the moving wheel 18 to the bottom of the conversion disk 16, thereby increasing the convenience of transferring the surveying instrument 10, and then, with the cooperation of the support frame 12 and the electric telescopic rod 11, control the surveying instrument 10 to perform highly stable transfer.

[0026] The above describes in detail the preferred implementation of this patent, but this patent is not limited to the above implementation. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of this patent.
