Description

Technical Field

[0001] This utility model relates to the field of surveying and mapping equipment technology. More specifically, this utility model relates to a surveying and mapping equipment suitable for complex terrain. Background Technology

[0002] Surveying work typically requires operation in complex terrain conditions, such as soft soil, hard rock, and rugged mountain roads. Current technology generally mounts the surveying instrument on a support frame, adjusting its level via the frame. The base of the support frame is usually spiked, but this structure is unsuitable for softer geological surfaces, as it can easily sink and cause the equipment to tilt; it is also unsuitable for hard rock surfaces, as stability cannot be guaranteed. Furthermore, during measurement, the surveying instrument needs to be rotated to adjust the surveying direction, but existing supports require rotating the entire frame and then readjusting the instrument's level, resulting in low operational efficiency. The rigid connections between the various structures of the support frame and between the support frame and the surveying instrument make it unable to withstand minor vibrations in the environment, affecting the accuracy of the measurement results. To solve these problems, it is necessary to provide a surveying device suitable for complex terrain. Utility Model Content

[0003] One object of this invention is to solve at least the problems described above and to provide at least the advantages that will be explained later.

The driven wheels are coaxially fixedly connected to the anchor pins. The output end of the driving device is used to drive the driving wheel to rotate, and the driving wheel drives each of the driven wheels to rotate.

[0010] Preferably, the top surface of the support platform has a downward-facing groove, and the bottom surface of the mounting platform has a fixed rotating shaft that matches the inner diameter of the groove.

[0011] Preferably, the height of the rotating shaft is greater than the depth of the groove, so that a gap is formed between the mounting platform and the supporting platform, and a second anti-slip pad is provided in the gap.

[0014] The surveying device provided by this utility model is suitable for complex terrain. It can be supported on the ground by anchor components or directly by support legs according to different terrain conditions to meet the stability requirements of complex terrain. During installation, the installation height of the surveying instrument can be adjusted by adjusting the length of the support legs, and the surveying direction of the surveying instrument can be adjusted by rotating the installation platform, which is easy to operate.

[0015] Other advantages, objectives and features of this invention will be partly apparent from the following description, and partly understood by those skilled in the art through study and practice of this invention. Attached Figure Description

[0018] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.

[0019] It should be noted that, unless otherwise specified, the experimental methods described in the following embodiments are all conventional methods, and the reagents and materials described are all commercially available unless otherwise specified. In the description of this utility model, the terms "lateral", "longitudinal", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0020] like Figure 1 As shown, this utility model provides a surveying device suitable for complex terrain, comprising:

[0021] A leveling base 2, with a ball head 8 embedded in the center of the leveling base 2, and a support platform 4 fixedly connected to the top of the ball head 8; a plurality of tension springs 3 are provided between the support platform 4 and the leveling base 2, and each tension spring 3 is symmetrically arranged about the center of the leveling base 2.

[0022] Mounting platform 6 is rotatably mounted on the support platform 4 for mounting the surveying instrument;

[0023] Multiple support legs 1 are hinged to the leveling base 2, and each support leg 1 is symmetrically arranged about the center of the leveling base 2; the support leg 1 is a telescopic structure, and its lower end is rotatably connected to an anchoring component 10, which can rotate to one side or below the support leg 1; a first anti-slip pad 9 is provided on the bottom surface of the support leg 1.

[0024] In this technical solution, upon reaching the measurement location, the opening angle of each support leg 1 relative to the leveling base 2 and the length of each support leg 1 are adjusted to ensure the mounting platform 6 is horizontal. Depending on the terrain, for example, on soft ground, the anchoring component 10 can be rotated to the bottom of the support leg 1 and fixed by extending into the ground; while on smooth rocks or rugged mountain roads, the support leg 1 is directly supported on the ground, with the anti-slip pad 9 increasing stability. Preferably, the thickness of the anti-slip pad is not less than 10mm to accommodate small protrusions. After mapping in one direction is completed, the mounting platform 6 is rotated to adjust the mapping direction of the surveyor. During the mapping process, low-frequency vibrations and slight sinking of any support leg 1 can be actively absorbed by the tension springs 3, ensuring the horizontal state of the surveyor. In actual use, the support leg 1 and the leveling base 2 can be connected by ear plates and bolts to fix the opening angle of the support leg 1. The support leg 1 can adopt a mechanical telescopic structure or an electric telescopic rod. Furthermore, the ball head 8 has a threaded through hole penetrating the center of the ball, and the leveling base 2 has a corresponding threaded hole on one side. When not in use, the ball head 8 can be locked by a screw passing through the threaded hole and the threaded through hole, thus turning it into a rigid support.

[0025] In another technical solution, such as Figure 2 As shown, the anchoring assembly 10 includes a U-shaped mounting bracket 11. The distance between the two side plates of the mounting bracket 11 is exactly the diameter of the support leg 1. The side plates are connected to the support leg 1 by bolts. A connecting block 13 is fixedly connected to the bottom of the mounting bracket 11. A plurality of anchoring nails 14 are provided at the bottom of the connecting block 13.

[0026] In this technical method, the U-shaped mounting bracket 11 enables the anchoring component 10 to rotate relative to the support leg 1. This allows the anchoring component 10 to rotate to the bottom of the support leg 1 for ground support, or to one side of the support leg 1 without obstructing the support leg 1 from directly supporting the ground. Multiple anchoring pins 14 also provide better stability compared to a single anchoring pin. In actual use, the position of the mounting bracket 11 can be adjusted first, and then the bolts tightened for fixation.

[0027] Furthermore, each anchor pin 14 is rotatably connected to the connecting block 13. The connecting block 13 contains a drive device 12 and a transmission gear set. The transmission gear set includes a driving wheel and multiple driven wheels corresponding one-to-one with each anchor pin 14. The driven wheels are coaxially and fixedly connected to the anchor pin 14. The output end of the drive device 12 drives the driving wheel to rotate, which in turn drives each driven wheel to rotate. The drive device 12 and the transmission gear set drive each anchor pin 14 to rotate synchronously. The drive device includes a micro motor and a reducer, and each anchor pin 14 has a spike at its bottom. When the surveying device is installed, but the mounting platform 6 is not level, the drive device 12 can be used to rotate the anchor pins 14 to slightly adjust the depth of the anchoring assembly 10 into the ground, thereby adjusting the levelness of the mounting platform 6 without adjusting the length of the support leg 1, thus avoiding any impact on the stability of the entire surveying device. In the initial stage of installing the surveying device, the driving device 12 and the transmission gear set can also drive each of the anchor pins 14 to be quickly inserted to a predetermined depth, which can be applied to terrains such as soft soil, clay, sand, and gravel mixture, further reducing the intensity of work.

[0028] In another technical solution, the top surface of the support platform 4 has a downward-facing groove, and the bottom surface of the mounting platform 6 has a fixed rotating shaft 5 that matches the inner diameter of the groove. The rotating shaft 5 and the groove are fitted with a clearance, and the rotating shaft 5 is inserted into the groove to allow the mounting platform 6 to rotate relative to the support platform 4.

[0029] Furthermore, the height of the rotating shaft 5 is greater than the depth of the groove, so that a gap is formed between the mounting platform 6 and the supporting platform 4, and a second anti-slip pad 7 is provided within the gap. The second anti-slip pad 7 is provided between the mounting platform 6 and the supporting platform 4 to ensure that the surveying instrument does not rotate during the surveying process. The second anti-slip pad 7 can be configured as a ring and fixed to the top surface of the supporting platform 4. When it is necessary to rotate the surveying instrument, the mounting platform 6 is manually rotated to overcome the friction between it and the second anti-slip pad 7.

[0030] In another technical solution, a tilt sensor is embedded in the center of the top surface of the mounting platform 6. The tilt sensor can directly determine the levelness of the mounting platform 6, thereby accurately adjusting the corresponding support leg 1 or the anchoring component 10; by embedding the sensor, the top surface of the tilt sensor does not protrude from the mounting platform 6, which facilitates the installation of the surveying instrument.

[0031] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and the illustrations shown and described herein.
