Description

Technical Field

[0001] This utility model relates to the field of engineering surveying technology, and in particular to a point marking device for engineering surveying. Background Technology

[0002] Engineering surveying refers to a series of activities conducted during the construction of engineering projects, using specialized surveying techniques and equipment to collect, analyze, and process data on natural terrain, buildings, and infrastructure to ensure the accuracy of design and construction. It is a fundamental task in engineering project management and implementation, covering surveying needs at all stages from design and construction to maintenance. In engineering surveying, point marking devices (often also called control points, benchmarks, or markers) are crucial tools used to ensure the accuracy and consistency of measurements. The main function of point marking devices is to provide stable and accurate reference coordinates and benchmarks for positioning, setting out, and monitoring throughout the engineering surveying process.

[0003] Currently, in engineering surveying work, point marking devices are commonly used to mark the measured locations. Common surveying instruments include RTK measuring instruments. However, after the existing measuring instruments have been used to measure and mark the points, another worker usually needs to sprinkle white powder on the marked locations. Manual marking requires workers to do it one by one, which is inefficient, especially in large-scale projects that require frequent marking. For long-term, high-intensity marking work, manual operation may consume a lot of time and manpower, increasing project costs. In addition, existing RTK measuring poles are manually supported during use, especially in windy, uneven ground, or high-altitude operations, as the poles are prone to swaying and do not have an auxiliary support function.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention.

[0026] Example 1:

[0027] Reference Figures 1-5 This is the first embodiment of the present invention. This embodiment provides a point marking device for engineering surveying. The point marking device for engineering surveying includes a marking mechanism 9. White powder is pre-filled inside the feeding tube 8 for later use. When the worker completes the point measurement and needs to mark the measurement location, he can press down the pressing rod 903. At this time, the pressing rod 903 moves downward within the fixed plate 902, causing the sealing plug 901 to move. Since the bottom of the feeding tube 8 is irregularly shaped, the sealing plug 901 moves downward, and the white powder at the top flows out from the inner wall of the feeding tube 8 and is sprinkled at the point through the oblique opening inside the feeding tube 8. During the movement of the sealing plug 901, the first spring 905 is stretched. When the pressing rod 903 is released, the first spring 905 will drive the sealing plug 901 to return to its original position, thereby achieving single-person point marking work, reducing labor costs and improving the efficiency of point marking.

[0028] An adjusting rod 2 is provided at the top of the inner cavity of the measuring rod 1. A clamp 3 is provided on the surface of the measuring rod 1. A handpiece 4 is installed on one side of the clamp 3. A moving station 5 is installed at the top of the adjusting rod 2. A first clamp 6 and a second clamp 61 are respectively provided on both sides of the bottom plate of the measuring rod 1. A positioning plate 7 is hinged between one side of the first clamp 6 and the second clamp 61. A feeding pipe 8 for storing marking powder is provided on the rear side of the measuring rod 1. A marking mechanism 9 is provided inside the feeding pipe 8. A support frame 10 is fixedly connected to the opposite sides of the first clamp 6 and the second clamp 61.

[0029] The measuring rod 1 facilitates the installation of the adjusting rod 2, while the clamp 3 facilitates the installation of the handpiece 4. The clamp 3 also contains a level and other devices, and together with the moving station 5, forms an RTK device. It should be noted that the measuring rod 1, adjusting rod 2, clamp 3, handpiece 4, and moving station 5 mentioned above are all mature devices with existing technology. Specific models can be selected according to actual needs and will not be elaborated here. The hinge between the first clamp 6 and the second clamp 61 and the positioning plate 7 facilitates the fixing of the first clamp 6 and the second clamp 61 to the surface of the measuring rod 1 for easy installation. An anti-slip rubber strip is provided between the first clamp 6 and the second clamp 61 to increase the friction between them and the measuring rod 1 during clamping. The feeding pipe 8 facilitates the storage of white powder used for marking, and the feeding pipe 8 has a special shape near its bottom to facilitate use with the marking mechanism 9. The support frame 10 facilitates the installation of the feeding pipe 8.

[0030] The marking mechanism 9 includes a sealing plug 901 and a fixing plate 902. The sealing plug 901 is disposed inside the feed tube 8. Both sides of the fixing plate 902 are fixedly connected to the inner wall of the feed tube 8. A pressing rod 903 is fixedly connected to the top of the sealing plug 901. The surface of the pressing rod 903 is slidably connected to the inside of the fixing plate 902. A cover plate 904 is slidably connected to the top of the surface of the pressing rod 903. The surface of the cover plate 904 is threadedly connected to the inside of the feed tube 8. A first spring 905 for auxiliary reset of the sealing plug 901 is fixedly connected between the top of the sealing plug 901 and the bottom of the fixing plate 902.

[0031] White powder is filled into the feed tube 8 for later use. When the staff completes the measurement and needs to mark the measurement location, they can press down the pressing rod 903. At this time, the pressing rod 903 moves downward within the fixed plate 902, causing the sealing plug 901 to move. Since the bottom of the feed tube 8 is irregularly shaped, the sealing plug 901 moves downward, and the white powder at the top will flow out from the inner wall of the feed tube 8 and sprinkle at the marked location through the slanted opening inside the feed tube 8. During the movement of the sealing plug 901, the first spring 905 will be stretched. When the pressing rod 903 is released, the first spring 905 will drive the sealing plug 901 to return to its original position. The first spring 905 is a high-strength spring and will not be affected by the weight of the powder, thus preventing it from not rebounding. The powder inside the feed tube 8 can also be selected according to actual needs, which will not be elaborated here. This allows for single-person marking work, reducing manpower and improving the efficiency of marking.

[0032] Example 2:

[0033] Reference Figures 1-5 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0034] Specifically, clamp brackets 11 are installed on the rear side of the two support brackets 10 by screws. The opposite sides of the two clamp brackets 11 are clamped to the irregular position of the feed tube 8. A plug rod 12 is fixedly connected to one side of the clamp bracket 11. Insert plates 13 that cooperate with the plug rod 12 are fixedly connected to both the front and rear sides of the surface of the feed tube 8.

[0035] The clamp bracket 11 can be easily fixed by screws through the support frame 10. One end of the clamp bracket 11 is designed in a semi-circular shape, which facilitates the limiting installation on the surface of the feed tube 8. The fixing of the clamp bracket 11 and the insertion rod 12, together with the insertion plate 13 on the surface of the feed tube 8, can limit and fix the feed tube 8, preventing the feed tube 8 from rotating inside the clamp bracket 11, which would cause the powder outlet to shift and affect the marking operation.

[0036] Specifically, a connecting plate 14 is fixedly connected to one side of the second clamp 61, and a positioning shell 15 is hinged inside the connecting plate 14. A U-shaped plate 16 is fixedly connected to one side of the first clamp 6. A lead screw 17 is rotatably connected inside the positioning shell 15. A torsion block 18 is fixedly connected to one end of the lead screw 17. A limiting ring 19 for positioning the first clamp 6 is fixedly connected to the surface of the lead screw 17. A rubber pad 20 is fixedly connected to one side of the limiting ring 19.

[0037] By hinged to the connecting plate 14 and the positioning shell 15, when the first clamp 6 and the second clamp 61 are fitted onto the surface of the measuring rod 1, the first clamp 6 and the second clamp 61 can be folded in half. Then, the positioning shell 15 is moved so that the lead screw 17 is locked inside the U-shaped plate 16. Subsequently, the torsion block 18 is rotated so that the lead screw 17 drives the limiting ring 19 to move against the U-shaped plate 16. The rubber pad 20 increases the stability of the installation between the limiting ring 19 and the U-shaped plate 16, thereby gradually reducing the gap between the first clamp 6 and the second clamp 61, so that they are firmly installed on the surface of the measuring rod 1. A rubber strip is also provided between the first clamp 6 and the second clamp 61 to improve the stability during installation.

[0038] Specifically, the top and bottom of the support frame 10 are fixedly connected with reinforcing blocks 21, and the opposite sides of the two reinforcing blocks 21 are fixedly connected to the first clamp 6 and the second clamp 61, respectively.

[0039] By fixing reinforcing blocks 21 to the top and bottom of the two support frames 10 respectively, and fixing the reinforcing blocks 21 to the first clamp 6 and the second clamp 61 respectively, the connection strength between the two support frames 10 and the first clamp 6 and the second clamp 61 can be improved.

[0040] Specifically, extension plates 22 are fixedly connected to the bottom of the front and rear sides of the support frame 10. An insertion cone 23 is provided inside the extension plate 22. A retaining ring 24 is fixedly connected to the top of the insertion cone 23. A positioning ring 25 is fixedly connected to the surface of the insertion cone 23. A second spring 26 is fixedly connected between the top of the positioning ring 25 and the bottom of the extension plate 22.

[0041] The extension plate 22 facilitates the limiting of the insertion cone 23, while the retaining ring 24 at the top of the insertion cone 23, together with the positioning ring 25, can limit the insertion cone 23 inside the extension plate 22. When the measuring rod 1 is driven into the ground, the insertion cone 23 will also be inserted into the soil. The setting of four insertion cones 23 helps to improve the stability of the staff when holding the measuring rod 1 for measurement. Furthermore, the setting of the second spring 26 will cause the positioning ring 25 to rise and squeeze the second spring 26 when the insertion cone 23 encounters a hard object or when the angle is adjusted, thereby achieving an auxiliary buffering effect.

[0042] In use, when first fitting the first clamp 6 and the second clamp 61 onto the surface of the measuring rod 1, the first clamp 6 and the second clamp 61 can be folded in half. Then, the positioning shell 15 is moved to make the lead screw 17 lock inside the U-shaped plate 16. Subsequently, the torsion block 18 is rotated to make the lead screw 17 drive the limiting ring 19 to move against the U-shaped plate 16. The rubber pad 20 increases the stability of the installation between the limiting ring 19 and the U-shaped plate 16, thereby gradually reducing the gap between the first clamp 6 and the second clamp 61, making it firmly installed on the surface of the measuring rod 1. A rubber strip is also provided between the first clamp 6 and the second clamp 61 to improve the stability during installation. Then, the clamp frame 11 is fixed to one side of the support frame 10 with screws, and the feeding pipe 8 is clamped between the two clamp frames 11 through the annular arrangement on one side of the clamp frame 11. At the same time, the clamp frame 11 and the The insertion rod 12 is fixed by inserting it into the insertion plate 13 on the surface of the feeding pipe 8, which limits and fixes the feeding pipe 8, preventing it from rotating inside the clamp bracket 11 and causing the powder outlet to shift, affecting the marking operation. Then, white marking powder is poured into the feeding pipe 8, and the cover plate 904 is placed on top. Measurement is then performed using the hand gripper 4 in conjunction with the clamp 3 and the moving station 5. When the measuring rod 1 is driven into the ground, the insertion cone 23 will also be inserted into the soil. The four insertion cones 23 help improve the stability of the measuring rod 1 when the operator holds it. The second spring 26, when the insertion cone 23 encounters a hard object or requires angle adjustment, will cause the positioning ring 25 to rise and compress the second spring 26, achieving a buffering effect. When the operator completes the measurement and needs to mark the measurement location, then…

[0043] The pressing rod 903 can be pressed down. Since the pressing rod 903 is slidably connected to the fixing plate 902 and the cover plate 904, the pressing rod 903 can move downward and drive the sealing plug 901 at the bottom to move. Since the bottom of the feeding tube 8 is irregularly shaped, the sealing plug 901 moves downward, and the white powder at the top will flow out from the inner wall of the feeding tube 8 and sprinkle at the fixed point through the slanted opening inside the feeding tube 8. During the movement of the sealing plug 901, the first spring 905 will be stretched. When the pressing rod 903 is released, the first spring 905 will drive the sealing plug 901 to reset, thereby achieving single-person fixed-point marking work, reducing manpower and improving the efficiency of fixed marking.

[0044] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
