Description

A high-precision elevation positioning device for deep cup rim foundation Technical Field

[0001] This utility model relates to the field of building construction technology, specifically a high-precision elevation positioning device for deep cup-shaped foundations. Background Technology

[0002] In the field of building construction, accurate elevation control is a crucial step in ensuring the quality of structural installation when constructing deep cup-shaped foundations (such as cup-shaped foundations for steel columns and pipe piles). Currently, when using elevation positioning devices, construction workers typically first use the positioning device to measure the elevation of the bottom of the cup, then remove the device to facilitate foundation hoisting. After the deep cup-shaped foundation is in place, the positioning device is reinstalled to measure the top elevation. This repeated disassembly and reassembly process not only increases working time and reduces efficiency but also fails to guarantee the consistency of the positioning device's installation position. It is prone to introducing human error during multiple installations, affecting measurement accuracy. Furthermore, the device's position needs to be adjusted during installation to ensure it is positioned above the deep cup-shaped foundation, further reducing work efficiency. Based on this, this application proposes a high-precision elevation positioning device for deep cup-shaped foundations. Summary of the Invention

[0003] This utility model provides a high-precision elevation positioning device for a deep cup-shaped foundation, which solves the problems mentioned in the background art, such as the need for multiple disassembly and assembly operations during use, which reduces work efficiency; multiple installations make it difficult to keep the elevation positioning device in a consistent position, affecting measurement accuracy; and the need to adjust the device position during installation, which further reduces work efficiency.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] This utility model provides an embodiment: Please refer to Figures 1-4. A high-precision elevation positioning device for a deep cup-mouth foundation includes a fixing ring 1 with evenly distributed fixing holes 2. Fixing screws 3 are installed in the fixing holes 2. In use, the fixing ring 1 can be fixed to the ground using the fixing screws 3. A locking hole 13 is provided on one side of the fixing ring 1, and a locking post 14 is provided in the middle of the bottom of the support column 4. The locking post 14 is adapted to the locking hole 13. Through the setting of the locking hole 13 and the locking post 14, the fixing ring 1 and the support column 4 can be locked or separated. In use, a cross-shaped valve can be provided at the top of the locking hole 13. When the locking post 14 is separated from the locking hole 13, the valve can seal the locking hole 13 to prevent impurities from falling into the locking hole 13 and facilitate the re-locking of the locking post 14 with the locking hole 13.

[0021] A positioning rod 6 is movably connected to the bottom end of the support column 4. A through groove 15 is provided at the bottom end of the support column 4. The positioning rod 6 is movably connected to the through groove 15. The positioning rod 6 is in a horizontal state. The support column 4 and the positioning rod 6 are in a mutually perpendicular state. The axis of the positioning rod 6 intersects with the geometric center axis of the fixing ring 1. A limit rod 7 is connected to the end of the positioning rod 6 away from the support column 4. The bottom of the limit rod 7 is located below the fixing ring 1. The limit rod 7 is located in the inner cavity of the fixing ring 1.

[0022] A limiting hole 17 is provided in the middle of the top of the through groove 15. A pressure rod is provided in the inner cavity of the limiting hole 17. When the positioning rod 6 is in the correct position, the pressure rod can be used to press the positioning rod 6 to fix its position, thereby fixing the position of the limiting rod 7. The pressure rod includes a screw section 5 that is threaded to the top of the inner cavity of the limiting hole 17 and a smooth rod section 16 that is movably connected to the inner cavity of the limiting hole 17. By setting the pressure rod, the user can change the position of the pressure rod in the limiting hole 17 by turning the pressure rod, thus releasing the restriction on the pressure rod. The threaded connection between the screw section 5 and the limiting hole 17 makes the position of the pressure rod fixed. An anti-slip pad is provided at the bottom of the smooth rod section 16. The anti-slip pad can increase the friction between the pressure rod and the positioning rod 6, improving the reliability of the fixed position of the positioning rod 6.

[0023] As described above, when using this device, the user can adjust the distance between the limiting rod 7 and the support column 4 as needed, so that the difference between the inner diameter of the fixing ring 1 and the inner diameter of the deep cup base hole is the same as the distance between the limiting rod 7 and the support column 4. This allows the user to easily align the fixing rod 7 with the inner wall of the deep cup base hole during installation, ensuring that the central axis of the fixing ring 1 and the central axis of the deep cup base hole are aligned, thus improving the ease and efficiency of determining the device's position. After the position of the fixing ring 1 is determined, it can be fixed using the fixing screw 3.

[0024] The top of the positioning rod 6 is provided with a scale line 12. Using the scale line 12, the user can accurately adjust the distance between the limiting rod 7 and the support column 4.

[0025] A leveling assembly is connected to the top of the support column 4 via a support rod 8. A mounting plate 9 is located at the bottom of the leveling assembly, above the center of the inner cavity of the fixing ring 1. An elevation positioning instrument 11 is mounted at the bottom of the mounting plate 9, and a level 10 is mounted at the top. The level 10 allows the user to visually determine if the elevation positioning instrument 11 is level. When the mounting plate 9 is not level, the user can adjust its position using the leveling assembly until it is level. The level 10 is publicly available technology and only needs to be able to detect whether the surface of an object is level. The elevation positioning instrument 11 is existing technology and only needs to be able to accurately measure and calibrate the vertical height of an object or structure relative to a reference plane; therefore, it will not be described in detail here.

[0026] The leveling assembly includes a first rotating block 19 movably connected to the end of the support rod 8 away from the support column 4. The first rotating block 19 is connected to the support rod 8 via a first bolt 20. A second rotating block 18 is movably connected to the bottom end of the first rotating block 19. The second rotating block 18 is connected to the first rotating block 19 via a second bolt 21. The mounting plate 9 is connected to the bottom of the second rotating block 18. The first bolt 20 and the second bolt 21 are perpendicular to each other. By setting up the leveling assembly, the user can adjust the levelness of the mounting plate 9 when adjusting the position of the first rotating block 19 and the second rotating block 18.

[0027] As described above, when using this device, the position of the limiting rod 7 is adjusted according to the needs. After the limiting rod 7 contacts the inner wall of the deep cup base hole, the fixing ring 1 is placed on the ground. At this time, the deep cup base hole is located in the middle of the inner cavity of the fixing ring 1. The fixing ring 1 is fixed with the fixing screw 3. After the position of the fixing ring 1 is fixed, the elevation positioning instrument 11 is located above the middle of the deep cup base hole. The elevation positioning instrument 11 can realize the bottom elevation of the deep cup base hole. When the deep cup base needs to be installed, the user can separate the support column 4 from the fixing ring 1 to avoid the structure connected to the support column 4 from affecting the installation of the deep cup base. When using the device again, the user can quickly fix the support column 4 and its connecting structure by engaging the locking hole 13 with the locking column 14. This allows the device to be put into use quickly, improves the installation efficiency, and enhances the ease of use. Furthermore, when the device is used again, the consistency of the installation position can be ensured, guaranteeing the accuracy of the device.
