Description

Technical Field

[0001] This utility model relates to the field of surveying and mapping devices, specifically a fixing frame structure for a surveying and mapping device used in land surveys. Background Technology

[0002] Surveying, literally understood, involves measuring and drawing. It selects existing feature points and boundaries on the ground and uses measurement methods to obtain graphic and positional information reflecting the current state of the ground for use in engineering construction, planning and design, and administrative management. When measuring feature points and boundaries on the ground, measuring tools are generally required. These tools are typically supported by a fixed frame, and most existing frames use three support legs, which provide effective support for the measuring tools. However, when the measuring tools need to be moved, the frame usually needs to be lifted and moved, but three support legs are inconvenient to fix, easily unfolding during movement, hindering movement, and even potentially causing injury. To address the aforementioned issues, a search revealed Chinese Patent CN218064245U, which discloses a mounting structure for a surveying device used in land surveys. The structure includes: a mounting base, with a mounting block fixedly connected to its upper surface; a through mounting hole between the mounting base and the mounting block; an inner spiral sleeve rotatably connected to the inner wall of the mounting hole; three through slots on the outer surface of the mounting base; support bars rotatably connected to the inner walls of each of the three through slots; and limit holes on the side walls of the support bars; and a limit assembly. Although the aforementioned device can rotate the three support bars inward and retract them, and is fixed by three limiting components, thus facilitating the movement of the device and preventing the three support bars from unfolding during movement, in actual use, surveying scenarios are mostly in the field (such as construction sites, mountains, and grasslands). The flatness and hardness of the ground directly affect the support stability of the tripod legs. If one leg rests on a low-lying area (such as a pothole or a gap in the gravel) and the other leg rests on a high area (such as a slope or a protruding rock), the "actual support height difference" between the two legs will cause the equipment to tip over, resulting in minor impacts to the instrument, damage to the outer casing, loosening of the interfaces, and affecting the service life of the equipment. Utility Model Content

[0003] The purpose of this utility model is to provide a fixing structure for a surveying device used in land surveys, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, a surveying device mounting frame structure for land surveying is provided, including a device mounting platform and a support frame. The device mounting platform has a receiving groove, and a connecting seat is movably mounted inside the receiving groove via a pin. The connecting seat is mounted on the top of the support frame, and a support frame is provided at its bottom. Meanwhile, a support leg is inserted inside the support frame, and a fixing post is provided at the end of the support leg. The fixing post passes through a receiving hole opened on the support frame and is screwed with a fixing nut.

[0005] Furthermore, the device mounting platform is circular, and three sets of support frames are equidistantly installed on the outer circumference of the device mounting platform, with the three sets of support frames having a centrally symmetrical structure.

[0006] Furthermore, the connecting seat is trapezoidal, and the support frame at the bottom of the connecting seat is rectangular. The support feet are inserted into the support frame to a certain depth by means of fixing posts and fixing nuts.

[0007] Furthermore, a force-bearing seat is installed on the outer side of the fixing nut, and the force-bearing seat is annular.

[0008] Furthermore, a force-bearing foot is fixedly provided at the bottom of the support foot, and the force-bearing foot is a conical structure made of metal.

[0009] Furthermore, the support frame also includes a stabilizing mechanism, and the three sets of support frames are brought together and limited by the stabilizing mechanism.

[0010] Furthermore, the stabilizing mechanism includes a locking frame, a receiving port, a screw thread, a nut, and a limiting seat; the locking frame is fixedly connected to the bottom of the device fixing platform, and three sets of receiving ports are equidistantly provided on its outer side, and a limiting seat is fixedly provided on each of the three sets of support frames, and the limiting seat is in contact with the side wall of the locking frame.

[0011] Furthermore, a screw post is fixedly connected to the support frame, and the screw post passes through the receiving opening and is screwed and fixed with a nut.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This solution addresses the challenges of complex terrain by employing three sets of independently height-adjustable support frames, coupled with tapered support feet, offering both height compensation and ground grip. For uneven terrain such as mountains and construction sites, the support feet interlaced within the support frame, combined with fixed columns and nuts, allow for individual adjustment of the extension length of each support frame. Effective contact of the support feet is achieved without needing a level surface. Even if the three legs are at different elevations, precise adjustment eliminates height differences. This results in a triangular arrangement of the three support frames, providing stable support for the device's mounting platform, preventing the surveying device from collapsing and extending its lifespan. 2. This solution uses a stabilizing mechanism to connect the three sets of support frames and the device mounting platform into a unified whole via a locking frame, completely solving the problem of loosening of the traditional support frames after closure, and reducing component damage during transportation and storage. In field operations, surveying equipment often needs to be moved by vehicle and manpower. The stabilizing mechanism, through the rigid fixation of bolts and nuts, firmly "locks" the support frames to the bottom of the device mounting platform, preventing shaking and collision during transportation and protecting critical components such as support legs and mounting columns. The three sets of support frames are precisely closed and limited by the stabilizing mechanism, preventing one-sided protrusion or loose opening. The overall storage volume is smaller, making it easier to put into an equipment box or transport bag, saving storage space. Attached Figure Description

Detailed Implementation

[0015] Please see Figure 1-5 This utility model provides a fixed frame structure for a surveying device used in land surveys, including a device fixing platform 100 and a support frame 200. The device fixing platform 100 has a receiving groove 101, and a connecting seat 201 is movably installed inside the receiving groove 101 via a pin. The connecting seat 201 is installed on the top of the support frame 200, and a support frame 202 is provided at its bottom. At the same time, a support leg 203 is inserted inside the support frame 202, and a fixing post 205 is provided at the end of the support leg 203. The fixing post 205 passes through a receiving hole opened on the support frame 202 and is screwed with a fixing nut 206.

[0016] Working principle: In actual use, the surveying device is installed on the device mounting platform 100, and the three sets of support frames 200 are opened. Support legs 203 are inserted inside the support frame 202 on the support frame 200. The distance between the support legs 203 and the support frame 202 can be adjusted by the fixing column 205 and the fixing nut 206. The height of the three sets of support frames 200 can be adjusted according to different ground conditions. At the same time, the force-bearing foot 204 at the bottom of the support leg 203 is conical and can be supported on the ground. By adjusting the height of the three sets of support frames 200, the device mounting platform 100 can be adjusted to a horizontal position. The independent height adjustment design of the three sets of support frames 200, together with the conical force-bearing foot 204, solves the problem of complex terrain from the dual dimensions of height compensation and ground grip. For uneven terrain such as mountainous areas and construction sites, the support legs 203 inserted inside the support frame 202, along with the cooperation of the fixing column 205 and the fixing nut 206, allow for individual adjustment of the extension length of each support frame 200. This ensures effective contact of the support legs 203 without requiring a level surface, and even if the three legs are at different elevations, precise adjustment can eliminate height differences. This results in the three support frames 200 forming a triangle, stably supporting the device's mounting platform 100, preventing the surveying device from collapsing and extending its service life.

[0017] In a preferred embodiment, the device fixing platform 100 is circular, and three sets of support frames 200 are equidistantly installed on the outer circumference of the device fixing platform 100, with the three sets of support frames 200 having a centrally symmetrical structure.

[0018] The connecting seat 201 is trapezoidal, and the support frame 202 at the bottom of the connecting seat 201 is rectangular. The support foot 203 is inserted into the interior of the support frame 202 and fixed by the fixing post 205 and the fixing nut 206.

[0019] A force-bearing seat 207 is installed on the outside of the fixing nut 206, and the force-bearing seat 207 is annular.

[0020] The bottom of the support leg 203 is fixedly provided with a load-bearing leg 204, and the load-bearing leg 204 is a conical structure made of metal.

[0021] like Figure 1-4As shown: The conical force-bearing foot 204 at the bottom of the support foot 203 can perform a piercing and gripping function: on soft ground such as soil and grass, the conical structure can penetrate the ground surface to form a deep anchor, preventing the support foot 203 from sinking; on hard and smooth ground such as rock and cement, the conical tip can fit the uneven surface, reducing the risk of lateral slippage and significantly improving the support reliability on different ground surfaces; the horizontal positioning of the device fixing platform 100 is achieved by finely adjusting the height of the three sets of support frames 200, which is the core foundation for ensuring the accuracy of surveying data; the measurement principle of surveying instruments relies on an absolutely horizontal reference plane. If the device fixing platform 100 is tilted, it will directly lead to systematic errors in data such as horizontal angle and elevation; in this design, the height of each set of support frames 200 can be independently adjusted by the relative displacement of the support foot 203 and the support frame 202. With the locking and positioning of the fixing column 205 and the fixing nut 206, the device fixing platform 100 can be finely calibrated to a horizontal state, eliminating the measurement deviation caused by tilting from the root and ensuring that the data accuracy meets the requirements of engineering specifications; The geometric characteristics of the three-point support inherently provide stability. Combined with the rigid connection between the support foot 203 and the support frame 202 through the fixing column 205 and the fixing nut 206, it can prevent the support foot 203 from loosening under the weight of the instrument or external forces. The conical force-bearing foot 204 further reduces the ground contact area, concentrates the weight of the device at the tip, and enhances the pressure transmission to the ground. Even in the event of strong winds, personnel touching or other external disturbances, it can reduce overall shaking and provide a stable working environment for the surveying instrument on the device mounting platform 100.

[0022] In a preferred embodiment, the support frame 200 also includes a stabilizing mechanism 208, and the three sets of support frames 200 are brought together and limited by the stabilizing mechanism 208.

[0023] The stabilizing mechanism 208 includes a locking frame 2081, a receiving port 2082, a screw thread 2083, a nut 2084, and a limiting seat 2085. The locking frame 2081 is fixed to the bottom of the device fixing platform 100, and three sets of receiving ports 2082 are equally spaced on its outer side. Limiting seats 2085 are fixedly installed on the three sets of support frames 202, and the limiting seats 2085 are in contact with the side wall of the locking frame 2081.

[0024] A screw post 2083 is also fixedly connected to the support frame 202, and the screw post 2083 passes through the receiving opening 2082 and is screwed and fixed with the nut 2084.

[0025] like Figure 4-5As shown: The locking frame 2081 is fixed to the bottom of the device fixing platform 100, providing a fixed reference for closing and limiting, and preventing the limiting structure from shifting itself; the three sets of receiving openings 2082 equidistantly opened on its outer side correspond one-to-one with the three sets of support frames 200, forcibly regulating the closing direction of the support frames 200 from the position, ensuring that the three sets of support frames 202 are symmetrically distributed after closing, and there will be no unilateral shift; the limiting seat 2085 on the support frame 202 is in close contact with the side wall of the locking frame 2081, forming a lateral limit. When closing, the limiting seat 2085 can slide along the side wall of the locking frame 2081, assisting the support frame 202 to accurately lock into the preset position, while preventing the support frame 202 from shaking in the horizontal direction; the screw post 2083 passes through The screw connection between the receiving port 2082 and the nut 2084 further forms an axial lock, firmly limiting the support frame 202 to the locking frame 2081, completely preventing the support frame 200 from scattering or shifting due to vibration or tilting after closure; the closure and limiting of the support frame 200 can be completed quickly without complicated tools, meeting the high-efficiency needs of field operations; simply pull the three sets of support frames 200 towards the center, align the screw post 2083 on the support frame 2085 with the receiving port 2082 of the locking frame 2081 and insert it, then screw the nut 2084 onto the screw post 2083 to complete the fixation. No additional parts need to be adjusted throughout the process, and it can be operated by a single person. Compared with traditional binding fixation or multi-clamp limiting, the closure time is greatly shortened; The stabilizing mechanism 208 connects the three sets of support frames 200 and the device fixing platform 100 into a unified whole through the locking frame 2081, which completely solves the problem of the traditional support frames being loose after being closed, and reduces component damage during transportation and storage. During field operations, surveying equipment often needs to be moved by vehicle and manpower. If the support frame 200 is not fixed after being closed, the support legs 203 and load-bearing legs 204 are prone to collisions with the device mounting platform 100 and other components due to bumps, resulting in deformation of the support frame 202 and wear of the load-bearing legs 204. The stabilizing mechanism 208, through the rigid fixation of the bolted post 2083 and the nut 2084, firmly "locks" the support frame 200 to the bottom of the device mounting platform 100, avoiding shaking and collisions during transportation and protecting key components such as the support legs 203 and the mounting post 205. The three sets of support frames 200 are precisely closed and limited by the stabilizing mechanism 208, preventing one side from protruding or loosely opening. The overall storage volume is smaller, making it easier to put into the equipment box or transport bag and saving storage space.
