Description

Technical Field

[0001] This application relates to the field of surveying and mapping technology. Specifically, it relates to a surveying and mapping marking device. Background Art

[0002] Surveying and mapping marking devices are widely used in various surveying and mapping works, including topographic mapping, engineering surveying, deformation measurement, etc. They are set on the ground that needs to be accurately measured as the reference points for measurement control. Through these marking devices, surveying and mapping personnel can establish accurate coordinate systems and elevation systems, providing reliable data support for subsequent engineering construction, urban planning and other works.

[0003] Currently, traditional surveying and mapping marking devices use fixed pins to firmly fix the columns on the ground to clearly mark the position and characteristics of the measurement points, enabling surveying and mapping personnel to accurately obtain the required data. When needed, surveying and mapping personnel can use various surveying instruments (such as total stations, GPS, etc.) to measure the marking devices to obtain the accurate coordinates or elevation data of the ground control points. However, over time and due to the influence of the natural environment, surveying and mapping marking devices also face challenges. The rod body is exposed to the outdoors for a long time, suffering from the erosion of sunlight and rain, as well as possible accidental collisions or human damage, which may cause the rod body to gradually wear or even be damaged. And since the rod body and the fixed pin are often integrally formed, once the rod body is damaged, it is difficult to replace it without disturbing the position of the base point, which undoubtedly brings quite a lot of trouble to the continuity and accuracy of surveying and mapping work. Utility Model Content

[0004] To make up for the above deficiencies, this application provides a surveying and mapping marking device to solve the problems raised in the above background art.

[0005] To achieve the above object, the technical solution adopted by the utility model to solve its technical problems is as follows:

[0006] A surveying and mapping marking device includes a telescopic rod. A base point anchoring assembly is provided at the bottom end of the telescopic rod. The base point anchoring assembly is composed of a threaded head, an anchor seat mechanism, an internal thread, and a clamping spring mechanism. The bottom end of the telescopic rod is integrally welded and formed with the top end of the threaded head. The inner side wall of the anchor seat mechanism is provided with the internal thread. The threaded head is arranged inside the anchor seat mechanism and is threadedly connected with the internal thread. The clamping spring mechanism is embedded in the side wall of the anchor seat mechanism.

[0007] Further, the inside of the threaded head is hollow and is inserted into the inner top end of the anchor seat mechanism.

[0008] Furthermore, the anchor base mechanism includes a ground nail cylinder, a ground nail, and a plug column. The bottom end of the ground nail cylinder is integrally formed with the top end of the ground nail, and the inner side wall is provided with the internal thread. The bottom end of the plug column is integrally formed with the inner bottom of the ground nail cylinder, and the top end is inserted into the inside of the threaded head.

[0009] Furthermore, the outer wall of the ground nail cylinder is self-equipped with a connecting edge. After the threaded head connected by internal threads is unscrewed, a rubber plug can still be sleeved, and the inside of the rubber plug fits against the outer wall of the plug column.

[0010] Furthermore, the snap spring mechanism includes two notches, two snap rods, and two springs. Two notches are respectively opened on both sides of the outer wall of the ground nail. The bottom ends of the two snap rods are respectively hinged to the inner bottoms of the two notches, and there is a certain space between the top ends and the inner tops of the notches. The two ends of the two springs are respectively fixedly connected to the two notches and the opposite surfaces of the two snap rods.

[0011] Furthermore, the outer wall of the telescopic rod is provided with a reference line and a reflective film.

[0012] The utility model has the following beneficial effects:

[0013] 1. By adopting the threaded connection mode between the threaded head and the anchor base mechanism, the utility model realizes the convenient disassembly and assembly of the telescopic rod and the base anchoring assembly. When the telescopic rod is worn or damaged due to long-term use, it can be easily removed from the anchor base mechanism and replaced by rotating the threaded head, without moving or damaging the base position, greatly improving the flexibility and maintainability of the device.

[0014] 2. The design of the anchor base mechanism of the utility model, especially the integral formation of the ground nail cylinder and the ground nail, and the addition of the snap spring mechanism, ensure the stable fixation of the anchor base mechanism on the ground. The snap spring mechanism is automatically locked after the ground nail is inserted into the soil through the action of the snap rod and the spring and in cooperation with the space at the inner top of the notch, preventing the anchor base mechanism from being accidentally pulled out or moved, thus improving the safety and reliability of the device.

[0015] 3. When the threaded head inside the ground nail cylinder is unscrewed, a rubber plug can be sleeved to seal the internal space. This design not only prevents external impurities from entering the inside of the anchor base mechanism, but also protects the plug column from corrosion and damage, extending the service life of the device.

Specific embodiments

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present application in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments.

[0026] Embodiment:

[0027] Please refer to Figure 1 , Figure 4 , Figure 5, A surveying and mapping marking device, including a telescopic rod 1. The telescopic rod 1 is made of high-strength lightweight alloy materials such as aluminum alloy or carbon fiber composite materials to ensure that it is both lightweight and durable, suitable for use under various terrain conditions. Inside the telescopic rod 1, there is a precise telescopic locking mechanism that allows users to adjust the length of the rod according to needs. The locking mechanism uses a quick-locking button or a rotary locking method to ensure that it can firmly maintain its position after adjusting the length and avoid accidental telescoping during the surveying process. On the outer wall of the telescopic rod 1, millimeter-level or higher-precision scale lines are precisely engraved along the length of the rod for use as reference lines. These scale lines should be clearly visible and not easily worn, so that surveyors can quickly and accurately read height or distance information. High-reflective films are attached to specific areas of the telescopic rod 1, such as the top, middle, or bottom. These areas should be selected according to the actual needs of the surveying operation to ensure that they can be quickly identified in the distance or under light reflection conditions. The above-mentioned telescopic rod 1 is prior art and will not be described in detail here.

[0028] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 , A surveying and mapping marking device. At the bottom end of the telescopic rod 1, there is a base point anchoring component 2. The base point anchoring component 2 is composed of a threaded head 21, an anchor seat mechanism 22, an internal thread 23, and a snap spring mechanism 24; the anchor seat mechanism 22 includes a ground nail cylinder 221, a ground drill nail 222, and a plugging column 223; a rubber plug 224 is sleeved on the inner top of the ground nail cylinder 221; the snap spring mechanism 24 includes two notches 241, two snap rods 242, and two springs 243.

[0029] Among them, the top end of the threaded head 21 is connected to the bottom end of the telescopic rod 1 through an integral welding forming technology to ensure a firm and reliable connection between the two, not easily loosening or falling off. The design of the threaded head 21 facilitates the threaded connection between the telescopic rod 1 and the anchor seat mechanism 22 through the internal thread 23, thereby providing stable support. The convenient disassembly and assembly of the telescopic rod 1 and the base point anchoring component 2 are realized. The inside of the threaded head 21 is designed to be hollow. This design can reduce material use and at the same time facilitate the plugging and matching with the plugging column 223. The hollow part can also be used as a channel for lubricating oil or other media, which helps to reduce friction and improve connection efficiency.

[0030] Among them, the anchor base mechanism 22 is a key part for the telescopic rod 1 to be stably connected to the ground. The ground nail cylinder 221 is a tubular structure, made of high-strength and corrosion-resistant materials such as stainless steel or aluminum alloy to ensure that it can be used for a long time in various harsh environments without being damaged; its bottom end is connected to the top end of the ground nail 222 by an integral molding method to ensure the firm and reliable connection between the two. A series of precise internal threads 23 are provided on the inner side wall of the ground nail cylinder 221, and the parameters such as the thread profile and pitch of these threads need to be precisely matched according to the design requirements of the thread head 21 to achieve smooth screwing and firm connection between the two. The ground nail 222 is a sharp conical or pointed cylindrical structure, made of cemented carbide or high-strength steel to ensure that it has sufficient hardness and toughness; its design is intended to facilitate penetration of soil or other ground materials to provide a stable support point for the surveying and marking device. The surface of the ground nail 222 can be coated with an anti-rust or wear-resistant coating to extend its service life. The insertion column 223 is a columnar structure, and its bottom end is connected to the inner bottom of the ground nail cylinder 221 by an integral molding method. The top end of the insertion column 223 is designed to have a shape and size matching the hollow inside of the thread head 21 to achieve the insertion fit between the two. The insertion column 223 is located at the center point of the anchor base mechanism 22, enabling the user to more accurately confirm the measurement point.

[0031] Among them, a circle of connecting edges is designed on the outer wall of the ground nail cylinder 221, and these connecting edges can be annular protrusions or grooves, used to increase the friction between the ground nail cylinder 221 and the surrounding soil or other fixtures to prevent it from being easily pulled out when subjected to external forces. At the same time, the connecting edge structure can also serve as a fulcrum for installing accessories or additional fixing devices. The rubber plug 224 is an elastic sealing member, usually made of rubber materials resistant to aging and wear. The inner shape of the rubber plug 224 matches the outer wall of the insertion column 223, and the outer wall matches the inner wall of the ground nail cylinder 221 to ensure a tight fit between the two. When the thread head 21 is unscrewed from the ground nail cylinder 221, the rubber plug 224 can be sleeved on the opening of the ground nail cylinder 221. In this way, the rubber plug 224 not only plays a sealing role, preventing moisture, dust and other impurities from entering the inside of the ground nail cylinder 221, but also can serve as a temporary dust cover or protective cover to protect the insertion column 223 from the influence of the external environment.

[0032] Among them, the internal thread 23 is a key structure inside the anchor base mechanism 22, which cooperates with the thread of the thread head 21 to achieve a fastening connection by rotation. The design of the internal thread 23 should meet the requirements of high precision and durability to ensure that there is no loosening or wear during long-term use.

[0033] Among them, the card spring mechanism 24 is used to enhance the fixing effect of the ground drilling nail 222 in the soil to prevent it from being accidentally pulled out due to external force. Two symmetrical notches 241 are respectively provided on both sides of the outer wall of the ground drilling nail 222 to provide sufficient movement space and installation position for the card rod 242. The size of the notch 241 needs to be precisely designed according to the specifications of the card rod 242 and the spring 243. The card rod 242 is a slender rod-shaped structure, and its material should have sufficient strength and toughness to withstand the lateral pressure of the soil on the ground drilling nail 222. The bottom end of the card rod 242 is connected to the inner bottom of the notch 241 by a hinged manner, allowing the card rod 242 to swing within a certain range. A certain space is left between the top of the card rod 242 and the inner top of the notch 241, so that under the action of soil pressure, the soil can enter the notch 241 through the space left between the top of the card rod 242 and the inner top of the notch 241, and the card rod 242 pops out and embeds into the soil. This design enhances the friction between the ground-boring nail 222 and the soil, and improves the stability of the fixation. Two springs 243 are respectively installed in the two notches 241, and their two ends are respectively fixedly connected to the wall of the notch 241 and the opposite surface of the clamping rod 242. The function of the spring 243 is to provide an outward thrust for the clamping rod 242, and when the soil pressure disappears or decreases, it can cause the clamping rod 242 to embed into the soil.

[0034] The working principle of the surveying and marking device: When in use, the ground drill nail 222 is first inserted into the ground at a predetermined position. The sharp design of the ground drill nail 222 enables it to easily penetrate the soil to the required depth; the bottom of the connecting edge of the outer wall of the ground nail tube 221 is fitted with the ground, and at the same time, the plug-in column 223 is located at the center of the base point. When the soil pressure on the side wall of the ground drill nail 222 disappears or decreases, the spring 243 installed inside the notch 241 pushes the clamping rod 242 outward to embed it into the soil. The inside of the threaded head 21 is aligned with the plug-in column 223, and the threaded head 21 is threadedly connected to the internal thread 23 in the ground nail tube 221 by rotating the telescopic rod 1; this threaded connection method ensures a stable connection between the telescopic rod 1 and the ground. It is convenient for subsequent users to survey and map it.

[0035] It should be noted that the specific model specifications of the threaded head 21 and the spring 243 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0036] It will be apparent to those skilled in the art that the present application is not limited to the details of the above-described exemplary embodiments, and that the present application can be implemented in other specific forms without departing from the spirit or essential characteristics of the present application. Therefore, in all respects, the embodiments should be considered exemplary and non-limiting. The scope of the present application is defined by the appended claims rather than the above description. Accordingly, all changes that fall within the meaning and scope of the equivalent elements of the claims are intended to be embraced within the present application. Any reference signs in the claims should not be construed as limiting the claims concerned.
