Description

Technical Field

[0001] This utility model relates to the field of surveying equipment technology, specifically to a grounding rod fixture for fixing a leveling rod. Background Technology

[0002] In the field of engineering surveying, leveling is an important method for determining the elevation difference between two points on the ground. It is widely used in various projects, such as elevation control in building construction, slope measurement of roads and bridges, and topographic mapping. The leveling rod is a key instrument in leveling, and the stability and accuracy of its fixing and erection play a decisive role in the measurement results.

[0003] Currently, in actual operation, the traditional method of fixing the leveling rod has many drawbacks. In most cases, it relies on manual holding of the leveling rod to keep it vertical. However, it is difficult for operators to support it stably for a long time, and it is very easy for it to sway. Therefore, there is an urgent need for a grounded leveling rod fixing fixture.

[0004] When using existing auxiliary leveling tools, they can either only achieve limited angle adjustment and cannot meet the needs of all-round measurement; or the adjustment structure is complicated and lacks intuitive and effective angle indication. In terms of height adjustment, many existing devices are cumbersome to operate and have poor accuracy. Some rely on manual pulling or rotating screws to change the height of the leveling rod, which not only consumes a lot of manpower and time, but also makes it difficult to achieve accurate height positioning. Utility Model Content

[0005] To address the aforementioned problems, this utility model discloses a grounding vertical rod fixture for fixing a leveling rod.

[0006] The technical solution of this utility model is: a grounding rod fixture for fixing a leveling rod, including a positioning rod, a sliding mounting plate sleeved on the outer wall of the positioning rod and slidable up and down, a leveling rod fixing frame provided on the side wall of the sliding mounting plate, and a leveling rod body installed on the leveling rod fixing frame.

[0007] The sliding mounting plate includes a sliding inner plate with several insertion slots on its side wall along the circumferential direction, and a sliding outer plate rotatably connected to the outer wall of the sliding inner plate. An operating handle is provided on the side wall of the sliding outer plate, and one end of the operating handle passes through the sliding outer plate and can extend into each of the insertion slots.

[0008] The leveling rod fixing frame is movably connected to the side wall of the sliding outer plate.

[0009] Furthermore, the outer wall of the positioning vertical rod is provided with several sliding vertical grooves along the circumference, and the inner wall of the sliding inner plate is provided with sliding strips that correspond one-to-one with the sliding vertical grooves and are slidably connected. One of the sliding vertical grooves is provided with a hydraulic cylinder for connecting the corresponding sliding strip.

[0010] Explanation: The cooperation between the sliding vertical groove and the sliding bar can precisely limit the sliding direction of the inner sliding plate on the positioning vertical rod, preventing it from rotating or deviating and ensuring the stability of the sliding process. The hydraulic cylinder provides convenient and stable power for the up and down movement of the inner sliding plate. By controlling the extension and retraction of the hydraulic cylinder, the height of the inner sliding plate and its associated outer sliding plate, leveling rod fixing frame and leveling rod body can be easily adjusted to meet the leveling rod height requirements of different measurement scenarios. The operation is labor-saving and highly accurate.

[0011] Furthermore, the upper end of the sliding inner plate is provided with an angle mark scale for displaying the rotation angle of the sliding outer plate, and the sliding outer plate is provided with an indicator arrow.

[0012] Explanation: The combination of angle markings and indicator arrows can intuitively reflect the rotation angle of the outer sliding plate relative to the inner sliding plate. During the measurement process, when it is necessary to adjust the orientation of the leveling rod body, the operator can observe the angle markings pointed to by the indicator arrows to accurately control the rotation angle, ensuring that the leveling rod body can be accurately aligned with the measurement direction, thus improving the accuracy of the measurement. This structure is particularly practical in some measurement operations with specific angle requirements.

[0013] Furthermore, the leveling rod fixing frame screw rod includes a vertical mounting plate screw rod connected to the side wall of the sliding outer plate screw rod, and two horizontal clamping frame screw rods that are parallel to each other, one end of which is slidably connected to the side wall of the vertical mounting plate screw rod and connected by an electric telescopic rod screw rod. The horizontal clamping frame screw rods have clamping recess screw rods on the side opposite to the vertical mounting plate screw rods. Each clamping recess screw rod has a fastening clamping plate screw rod inside. The upper end of the fastening clamping plate screw rod is connected to a screw rod that extends to the outside. The upper and lower ends of the leveling rod body screw rod are placed inside the two clamping recess screw rods.

[0014] Instructions: The vertical mounting plate provides a stable mounting base for the horizontal clamping frame. The two horizontal clamping frames are connected by an electric telescopic rod, which can be used to adjust the distance between them to accommodate leveling rods of different lengths. In use, the leveling rod is placed in the clamping recesses of the two horizontal clamping frames. Tightening the screw and the fastening plate further securely fixes the leveling rod in the clamping recesses. Tightening the screw moves the fastening plate closer to the leveling rod and applies pressure, ensuring that the leveling rod does not loosen or shake during measurement, thus guaranteeing the reliability of the measurement data.

[0015] Furthermore, the bottom end of the outer wall of the positioning vertical rod is threadedly connected to a threaded connecting sleeve, and the bottom end of the threaded connecting sleeve is circumferentially hinged with several plug rods, and each plug rod is provided with a plug cone at its bottom end. The bottom end of the sliding inner plate is connected to several hooks through an elastic pull rope, and the upper end of the threaded connecting sleeve is provided with several hanging rings that correspond one-to-one with the hooks.

[0016] Note: The threaded connection between the threaded connecting sleeve and the positioning vertical rod facilitates disassembly, assembly, and adjustment of its position on the positioning vertical rod. The insertion cone at the bottom of the insertion rod can be easily inserted into the ground, enhancing the stability of the entire fixture and preventing the positioning vertical rod from tipping over during measurement. The hook on the elastic pull rope at the bottom of the sliding inner plate is hung on the corresponding hanging ring at the top of the threaded connecting sleeve. The tension of the elastic pull rope can be used to pull and fix the insertion rod, improving the installation stability of the sliding mounting plate and the leveling rod fixing frame.

[0017] Furthermore, the elastic pull rope includes several spring posts and a fixed post disposed between two adjacent spring posts.

[0018] Explanation: When subjected to tension, the spring column can stretch to a certain extent, thus adapting to different distance changes between the hook and the hanging ring. At the same time, it can generate a rebound force after stretching, ensuring the pulling force on the plug rod. The fixing column plays the role of connecting and stabilizing the spring column, preventing the spring column from excessive bending or twisting during stretching or contraction, ensuring the stability and service life of the overall structure of the elastic pull rope, and enabling the elastic pull rope to continuously and reliably perform its pulling and fixing function.

[0019] The beneficial effects of this utility model are:

[0020] In use, the grounding rod fixture for fixing a leveling rod of this utility model uses a sliding mounting plate as the basic support structure. The sliding mounting plate, mounted on the sliding mounting plate, slides up and down along the positioning vertical rod, which can be used to adjust the height of the leveling rod. At the same time, the relative rotation between the inner and outer sliding plates of the sliding mounting plate can be used to adjust the angle of the leveling rod. During the adjustment process, the angle can be precisely controlled by observing the angle mark scale pointed to by the tip of the indicator arrow, ensuring that the leveling rod body can be accurately aligned with the measurement direction, thus improving the accuracy of the measurement. This structure is particularly practical in some measurement operations with specific angle requirements. In summary, the grounding rod fixture for fixing a leveling rod significantly improves measurement efficiency and data reliability, providing stable, accurate, and convenient tooling support for leveling work.

Detailed Implementation

[0026] Example 1: As Figure 1 As shown, a grounding rod fixture for fixing a leveling rod includes a positioning vertical rod 1, a sliding mounting plate 2 sleeved on the outer wall of the positioning vertical rod 1 and slidable up and down, a leveling rod fixing frame 3 provided on the side wall of the sliding mounting plate 2, and a leveling rod body 4 installed on the leveling rod fixing frame 3. The leveling rod body 4 adopts existing technology, such as existing 4J36 ultra-low thermal expansion indium alloy steel.

[0027] like Figure 2 , 3 As shown, the sliding mounting plate 2 includes a sliding inner plate 20 with 18 insertion slots 200 on its sidewalls along the circumferential direction, and a sliding outer plate 21 rotatably connected to the outer wall of the sliding inner plate 20. An operating handle 22 is provided on the sidewall of the sliding outer plate 21. One end of the operating handle 22 passes through the sliding outer plate 21 and can extend into each insertion slot 200. The sliding inner plate 20 and the outer wall of the sliding outer plate 21 are rotatably connected. The core is to realize the relative circumferential rotation of the two around the same axis. For example, an annular groove can be processed on the outer wall of the sliding inner plate 20 at the upper and lower ends of the insertion slots 200. An annular flange that fits into the annular groove is provided on the inner wall of the sliding outer plate 21, which realizes rotation guidance and prevents axial separation.

[0028] The leveling rod fixing frame 3 is hinged to the side wall of the sliding outer plate 21, and the connection is also equipped with an existing locking device, such as an adjustable hinge lock of model CL225-2.

[0029] The outer wall of the positioning vertical rod 1 is provided with four sliding vertical grooves 10 along the circumference. The inner wall of the sliding inner plate 20 is provided with sliding strips 201 that correspond one-to-one with the sliding vertical grooves 10 and are slidably connected. One of the sliding vertical grooves 10 is provided with a hydraulic cylinder 202 for connecting the corresponding sliding strip 201. The cooperation between the sliding vertical groove 10 and the sliding strip 201 can accurately limit the sliding direction of the sliding inner plate 20 on the positioning vertical rod 1, prevent it from rotating or deviating, and ensure the stability of the sliding process. The hydraulic cylinder 202 provides convenient and stable power for the up and down movement of the sliding inner plate 20. By controlling the extension and retraction of the hydraulic cylinder 202, the height of the sliding inner plate 20 and the associated sliding outer plate 21, the leveling rod fixing frame 3 and the leveling rod body 4 can be easily adjusted to meet the requirements of the leveling rod height in different measurement scenarios. The operation is labor-saving and highly accurate. The hydraulic cylinder 202 adopts existing technology, such as the HSG series piston hydraulic cylinder.

[0030] The upper end of the sliding inner plate 20 is provided with an angle mark scale 210 for displaying the rotation angle of the sliding outer plate 21. The sliding outer plate 21 is provided with an indicator arrow 211. The cooperation of the angle mark scale 210 and the indicator arrow 211 can intuitively reflect the rotation angle of the sliding outer plate 21 relative to the sliding inner plate 20. During the measurement process, when it is necessary to adjust the orientation of the leveling rod body 4, the operator can observe the angle mark scale 210 pointed to by the tip of the indicator arrow 211 to accurately control the rotation angle, ensuring that the leveling rod body 4 can be accurately aligned with the measurement direction, thus improving the accuracy of the measurement. This structure is particularly practical in some measurement operations with specific requirements for angles. The range of the angle mark scale 210 is 360°. In order to ensure that the sliding inner plate 20 can have a matching insertion slot 200 with the operating handle 22 when rotated to each angle, the edges of two adjacent insertion slots 200 are tightly fitted without gaps.

[0031] like Figure 4 As shown, the leveling rod fixing frame 3 includes a vertical mounting plate 30 connected to the side wall of the sliding outer plate 21, and two horizontal clamping frames 31 that are parallel to each other and have one end slidably connected to the side wall of the vertical mounting plate 30 and connected by an electric telescopic rod 310. The horizontal clamping frames 31 have clamping recesses 311 on the side opposite to the vertical mounting plate 30. Each clamping recess 311 has a fastening clamping plate 313. The upper end of the fastening clamping plate 313 is connected to a screw rod 312 that extends to the outside. The upper and lower ends of the leveling rod body 4 are placed in the two clamping recesses 311. The electric telescopic rod 310 adopts existing technology, such as the electric telescopic rod of model DTZ1000.

[0032] The vertical mounting plate 30 provides a stable mounting base for the horizontal clamping frame 31. The two horizontal clamping frames 31 are connected by an electric telescopic rod 310. The distance between the two horizontal clamping frames 31 can be adjusted by extending and retracting the electric telescopic rod 310 to accommodate leveling rod bodies 4 of different lengths. In use, the leveling rod body 4 is placed in the clamping recesses 311 of the two horizontal clamping frames 31. The cooperation of the screw 312 and the fastening clamping plate 313 can further fix the leveling rod body 4 firmly in the clamping recesses 311. By tightening the screw 312, the fastening clamping plate 313 is driven to move closer to the leveling rod body 4 and apply pressure to ensure that the leveling rod body 4 will not loosen or shake during the measurement process, thus ensuring the reliability of the measurement data.

[0033] The bottom of the outer wall of the positioning vertical rod 1 is threadedly connected to a threaded connecting sleeve 11. Four insertion rods 110 are circumferentially hinged to the bottom of the threaded connecting sleeve 11, and each insertion rod 110 has an insertion cone 111 at its bottom. The bottom of the sliding inner plate 20 is connected to four hooks 204 via an elastic pull rope 203. The upper end of the threaded connecting sleeve 11 has four hanging rings 112 corresponding to the hooks 204. The threaded connection between the threaded connecting sleeve 11 and the positioning vertical rod 1 facilitates disassembly, assembly, and adjustment during positioning. Positioned on the vertical rod 1, the insertion cone 111 at the bottom of the insertion rod 110 can be easily inserted into the ground, enhancing the stability of the entire fixture and preventing the positioning vertical rod 1 from tipping over during measurement. The hook 204 on the elastic pull rope 203 at the bottom of the sliding inner plate 20 is hung on the corresponding hanging ring 112 at the upper end of the threaded connecting sleeve 11. The tension of the elastic pull rope 203 can be used to pull and fix the insertion rod 110, improving the installation stability of the sliding mounting plate 2 and the leveling rod fixing frame 3.

[0034] The elastic pull rope 203 includes four spring posts 2030 and a fixed post 2031 located between two adjacent spring posts 2030. When subjected to tension, the spring posts 2030 can stretch to a certain extent to adapt to different distance changes between the hook 204 and the hanging ring 112. At the same time, it can generate a rebound force after stretching to ensure the pulling force on the plug rod 110. The fixed post 2031 plays the role of connecting and stabilizing the spring posts 2030, preventing the spring posts 2030 from excessively bending or twisting during stretching or contraction, ensuring the stability and service life of the overall structure of the elastic pull rope 203, and enabling the elastic pull rope 203 to continuously and reliably perform its pulling and fixing function. The spring posts 2030 can be existing cylindrical helical compression springs.

[0035] The working principle of this utility model of a grounding rod fixing fixture includes the following steps:

[0036] S1. Rotate the threaded connecting sleeve 11 at the bottom of the positioning vertical rod 1 to a suitable height, unfold each hinged plug rod 110 outward, and insert it into the ground through the plug cone head 111 at the bottom to form a radial support structure centered on the positioning vertical rod 1, which initially resists the tilting moment of the positioning vertical rod 1.

[0037] S2. The hydraulic cylinder 202 drives the corresponding sliding bar 201 to slide up and down in the sliding vertical groove 10, while the other sliding bars 201 move up and down synchronously. At the same time, the inner sliding plate 20 and the outer sliding plate 21 slide on the positioning vertical rod 1, thereby achieving the purpose of adjusting the height of the leveling rod fixing frame 3.

[0038] S3. Pull out the operating handle 22 and rotate the sliding outer plate 21. While rotating, you can accurately control the rotation angle by observing the angle mark 210 pointed to by the tip of the indicator arrow 211. When the desired angle is reached, insert the operating handle 22 into the corresponding angle insertion slot 200.

[0039] S4. The distance between the two horizontal clamping frames 31 can be adjusted by extending and retracting the electric telescopic rod 310, so as to accommodate the leveling rod body 4 of different lengths. When in use, the leveling rod body 4 is placed in the clamping recess 311 of the two horizontal clamping frames 31. By tightening the screw 312, the fastening clamping plate 313 is driven to move closer to the leveling rod body 4 and apply pressure to ensure that the leveling rod body 4 will not loosen or shake during the measurement process.

[0040] S5. The elastic pull rope 203 at the bottom of the sliding inner plate 20 is connected to the hanging ring 112 of the threaded connecting sleeve 11 via the hook 204. Finally, the measurement can be performed by the leveling rod body 4.
