Description

Technical Field

[0001] This application relates to the technical field of underground foundations for traffic poles, and in particular to an underground foundation for traffic poles that is easy to replace and a replacement method. Background Technology

[0002] Currently, the underground foundations for traffic poles mainly employ two methods: First, traditional concrete pouring fixation, where the traffic pole is directly cast into the concrete foundation. This method offers good stability but is difficult to replace, limiting its application. Second, removable foundations, such as flange connections, are used. Flanges are pre-embedded in the underground foundation, and similar flanges are fixed to the lower end of the traffic pole, connecting them via bolts. This method is more convenient for disassembly and replacement. However, in some smart city upgrades, it is necessary to upgrade and replace the poles. The flange hole spacing of the updated poles changes, making them incompatible with the original underground foundation, thus significantly impacting the pole replacement work. Summary of the Invention

[0003] Firstly, this application provides an underground foundation for traffic poles that is easy to replace.

[0004] The technical solution adopted in this application is as follows: An easily replaceable underground foundation for traffic poles includes a foundation base, a connecting plate on the foundation base, and a connector on the connecting plate for connecting to a flange at the lower end of the pole. The connecting plate has multiple adjusting grooves evenly distributed circumferentially and extending radially. The connector includes a connecting rod passing through the adjusting groove and a threaded seat threaded to the outer wall of the connecting rod, the threaded seat abutting against the flange of the pole. A clearance groove is formed on the upper surface of the foundation base, and the lower end of the connecting rod is a block-shaped structure located within the clearance groove. A receiving groove is formed at the center of the foundation base, and an extension is provided within the receiving groove. The extension passes through the connecting plate and extends into the inner cavity of the pole. A support is provided on the side wall of the extension. A trigger is provided on the connecting plate, passing through the connecting plate and threaded into the foundation base, and capable of driving the support to abut against the inner wall of the pole.

[0005] By adopting the above technical solution, an adjustment groove is provided on the connecting plate, and the connecting rod can be adjusted radially within the adjustment groove. This allows the connecting rod to be adjusted according to the position of its holes for flanges with varying dimensions, thus better adapting to different rods. An extension is installed at the center of the base. When the rod is installed on the connecting plate, a trigger can drive the support to press against the inner wall of the rod, thereby enabling the extension to position the rod, limiting the possibility of displacement, and further improving the stability of the rod installation.

[0006] Optionally, the extension includes a fixed seat installed in the receiving groove and an extension column installed in the fixed seat. The extension column passes through the connecting plate and extends into the inner cavity of the rod. The support is installed on the outer wall of the extension column, and multiple sets of the support are evenly arranged along the circumference of the extension column. The extension column has an internal hollow structure and is slidably connected to a sliding member. The trigger can drive the sliding member to slide downward so that the support can press against the inner wall of the rod.

[0007] By adopting the above technical solution, multiple sets of support members are provided circumferentially on the outer wall of the extended column, thereby improving the support effect on the members.

[0008] Optionally, the side wall of the extension column is provided with a sliding groove extending along the axial direction. The support includes multiple mounting seats installed in the sliding groove and two support rods hinged to the mounting seats. The ends of the two support rods away from the mounting seats are respectively hinged to adjacent support rods. The lowermost mounting seat is fixed in the sliding groove, and the remaining mounting seats are slidably installed in the sliding groove. The uppermost mounting seat is connected to the sliding member so that the sliding member slides and drives the mounting seat to slide.

[0009] By adopting the above technical solution, the upper and lower support rods can form a triangular structure. The uppermost mounting base is connected to the sliding member. When the sliding member slides down, the end of the support rod can move away from the extension column and abut against the inner wall of the rod. When the sliding member moves up to reset, the support member can form a frustum-shaped structure that is smaller at the top and larger at the bottom, making it easier for the extension member to be inserted into the inner cavity of the rod during installation.

[0010] Optionally, the sliding member includes a sliding column slidably disposed in the inner cavity of the extension column, the uppermost mounting seat being connected to the side wall of the sliding column, the sliding column having a cavity, an adjusting rod being threadedly connected to the upper end of the extension column, the lower end of the adjusting rod slidably passing through the upper end of the sliding column and extending into the cavity, and a first elastic element being disposed between the lower end of the adjusting rod and the top surface of the cavity.

[0011] By adopting the above technical solution, the initial position of the sliding column can be adjusted by adjusting the position of the adjusting rod, so that the support component can better fit the inner diameter of the rod, which is conducive to the installation of the rod. Then, the sliding column is driven to slide downward by the trigger component, so that the support rod is pressed against the inner wall of the rod.

[0012] Optionally, the lower end sidewall of the extension column is provided with a slot, the lower end of the sliding column is provided with an abutment rod, the abutment rod extends from the slot, the inner wall of the receiving groove is provided with an abutment groove, the abutment groove extends in the vertical direction, and the abutment rod extends in the abutment groove; the lower end of the triggering member extends in the abutment groove and abuts against the abutment rod to drive the sliding column to move downward, and the first elastic member is compressed.

[0013] By adopting the above technical solution, when the sliding column slides, the abutment rod can move in the slot, and the trigger extends into the abutment groove and abuts against the abutment rod, so that the downward movement of the trigger can push the sliding column to slide, thereby driving the mounting base to slide.

[0014] Optionally, the trigger is a reinforcing bolt, which passes through the flange of the rod and the connecting plate and is threaded into the base, with the lower end of the reinforcing bolt extending into the abutment groove.

[0015] By adopting the above technical solution, the lower end of the reinforcing bolt abuts against the abutting rod, which can push the movement of the abutting rod.

[0016] Optionally, a second elastic element is provided between the upper and lower adjacent mounting seats.

[0017] By adopting the above technical solution, a certain supporting force can be formed between the upper and lower adjacent mounting seats, so that in the initial state, the support can better form a frustum structure that is smaller at the top and larger at the bottom.

[0018] Optionally, the outer wall of the extension column is threaded with a locking block, which abuts against the surface of the connecting disc.

[0019] Optionally, the inner wall of the receiving groove is provided with a mounting groove for the abutment rod to pass through. The mounting groove has a vertical section and a horizontal section. The horizontal section is located at the lower end of the vertical section and is connected to the abutment groove.

[0020] In summary, this application includes at least one of the following beneficial effects: 1. The rods are connected by flanges and connecting plates, which makes installation and disassembly convenient. The connecting rods can be adjusted in the adjustment groove to better adapt to the installation of different rods. 2. The extension can extend into the inner cavity of the rod and support it, thereby improving the stability of the connection. Attached Figure Description

[0023] The present application will be further described in detail below with reference to the accompanying drawings.

[0024] This application discloses an underground foundation for easily replaceable traffic poles. (Refer to...) Figure 1 and Figure 2 It includes a foundation base 1, which is a prefabricated component buried underground. A connecting plate 2 is fixed to the upper end of the foundation base 1 by means of buried bolts, etc. A connecting piece 3 is installed on the connecting plate 2. A flange is fixed to the outer wall of the lower end of the rod. The connecting piece 3 is used to connect the flange at the lower end of the rod to the connecting plate 2, thereby positioning the rod.

[0025] Reference Figure 2 and Figure 3 The connecting plate 2 has a circular structure and multiple adjusting grooves 4 are provided on it. Multiple sets of adjusting grooves 4 are evenly arranged along the circumference of the connecting plate 2, and their number is determined according to the number of holes in a typical flange. In this embodiment, six adjusting grooves 4 are provided. The adjusting grooves 4 extend radially along the connecting plate 2.

[0026] The connecting member 3 includes a connecting rod 31 passing through the adjusting groove 4 and a threaded seat 32 threaded to the outer wall of the connecting rod 31. The lower end of the connecting rod 31 has a block structure, and a relief groove 5 is provided on the surface of the base 1. The lower end of the connecting rod 31 is located in the relief groove 5, which provides space for the lower end of the connecting rod 31 and prevents the connecting rod 31 from rotating in the adjusting groove 4. The upper end of the connecting rod 31 passes through the adjusting groove 4 and through the mounting hole on the rod flange. The threaded seat 32 is threaded onto the upper end of the connecting rod 31 and can press downward against the upper surface of the rod flange, thereby fixing the flange to the connecting plate 2. Since the adjusting groove 4 extends radially, the connecting rod 31 can move radially in the adjusting groove 4 to adapt to different mounting hole positions on different rod flanges.

[0027] Reference Figure 2 , Figure 3 and Figure 4 The base 1 has a receiving groove 6 at its center, and an extension 7 is installed in the receiving groove 6. The extension 7 extends vertically upward and passes through the center of the connecting plate 2, extending into the inner cavity of the rod. A support 8 is installed on the side wall of the extension 7. After the rod is installed on the connecting plate 2, the support 8 can abut against the inner wall of the rod, thereby positioning the rod, limiting the rod from shifting, and also limiting the rod from bending to a certain extent, thus improving its wind resistance.

[0028] Reference Figure 3 and Figure 4 The extension member 7 includes a fixing base 71 and an extension column 72. The fixing base 71 is installed at the bottom of the receiving groove 6 and can be fixed to the foundation base 1 by anchor bolts or embedded parts, or by bonding with cement or other methods. The extension column 72 is vertically installed on the fixing base 71 and extends upward through the center of the connecting plate 2. The support member 8 is installed on the outer wall of the extension column 72. In this embodiment, four sets of support members 8 are provided and are evenly distributed along the circumferential direction of the extension column 72.

[0029] The sidewall of the extension column 72 has sliding grooves 11 extending along its axis. The number of sliding grooves 11 corresponds to the number of support members 8, and each sliding groove 11 houses a set of support members 8. Each support member 8 includes multiple mounting seats 81 installed in the sliding groove 11 and two support rods 82 hinged to the mounting seats 81. The lowermost mounting seat 81 is fixed to the lower end of the sliding groove 11, while all the upper mounting seats 81 are slidably installed in the sliding groove 11. The sliding groove 11 can be a T-shaped structure or a dovetail structure. The cross-section of the mounting seat 81 is adapted to the sliding groove 11, allowing the mounting seat 81 to slide stably within the sliding groove 11. The end of the support rod 82 furthest from the mounting seat 81 is hinged to the support rod 82 on the adjacent mounting seats 81 above and below, forming a scissor-type telescopic structure between the adjacent mounting seats 81 via the support rods 82. When the uppermost mounting base 81 slides downward, the entire support rod 82 expands laterally, causing the hinge point of the support rod 82 to move outward and thus press against the inner wall of the rod.

[0030] Reference Figure 4 and Figure 5 The extension column 72 has an internal hollow structure, and a sliding member 10 is slidably disposed in the inner cavity of the extension column 72. The uppermost mounting seat 81 is connected to the sliding member 10. The connecting plate 2 is also equipped with a trigger member 9, which can drive the sliding member 10 to slide downward so that the support member 8 is pressed against the inner wall of the rod.

[0031] The sliding member 10 includes a sliding column 101, which is a cylindrical rod with an outer diameter matching the inner diameter of the extension column 72. The upper end of the sliding groove 11 has a hollow structure, allowing the uppermost mounting seat 81 to be fixedly connected to the side wall of the sliding column 101 via a fixed support rod. When the sliding column 101 slides up and down, it drives the uppermost mounting seat 81 to move synchronously. A cavity 12 is provided at the upper end of the sliding column 101, and an adjusting rod 13 is threadedly connected to the upper end of the extension column 72. The lower end of the adjusting rod 13 slides through the upper end surface of the sliding column 101 and extends into the cavity 12 of the sliding column 101. A first elastic element 14 is provided between the lower end of the adjusting rod 13 and the inner top surface of the cavity 12. The first elastic element 14 is a spring, which is sleeved on the outer wall of the adjusting rod 13 and connected between the lower end of the adjusting rod 13 and the inner top surface of the cavity 12. By rotating the adjusting rod 13, the position of the lower end of the adjusting rod 13 can be changed, thereby adjusting the initial height of the sliding column 101, and thus adjusting the initial expansion degree of the support member 8 to accommodate rods with different inner diameters.

[0032] Reference Figure 3 and Figure 4The lower side wall of the extension column 72 has a slot 15 that extends vertically for a certain length. The lower end of the sliding column 101 is fixedly connected to an abutment rod 17, which extends horizontally outward and passes through the slot 15. The inner wall of the receiving groove 6 has an abutment groove 16 that extends vertically and corresponds to the position of the abutment rod 17. One end of the abutment rod 17 extends into the abutment groove 16 and can slide up and down within it. The inner wall of the receiving groove 6 also has an installation groove 20 for the abutment rod 17 to pass through during installation. The installation groove 20 has a vertical section and a horizontal section. The vertical section extends downward from the upper end of the receiving groove 6, and the horizontal section is located at the lower end of the vertical section and communicates with the abutment groove 16. When installing the extension 7, first align the abutment rod 17 with the vertical section of the mounting groove 20 and insert it. Then rotate the extension column 72 to make the abutment rod 17 enter the abutment groove 16 along the horizontal section, thereby locking the extension 7 in the receiving groove 6.

[0033] Reference Figure 3 The trigger element 9 is a reinforcing bolt 91. The reinforcing bolt 91 passes sequentially from top to bottom through the flange and connecting plate 2 of the rod, and is threaded into the base base 1. A threaded sleeve is pre-embedded in the base base 1 for the threaded connection of the reinforcing bolt 91. The specific length of the reinforcing bolt 91 can be selected according to actual conditions. The lower end of the reinforcing bolt 91 continues downward, extending into the contact groove 16, and finally abutting against the upper surface of the contact rod 17. When the reinforcing bolt 91 is tightened downward, the lower end of the reinforcing bolt 91 pushes the contact rod 17 downward. The contact rod 17 drives the sliding column 101 to slide downward, compressing the first elastic element 14. At the same time, the sliding column 101 drives the uppermost mounting seat 81 to move downward, causing the scissor structure of the support member 8 to expand outward, and the hinge point of the support rod 82 to push outward, abutting against the inner wall of the rod. The upper end of the reinforcing bolt 91 abuts against the flange, and some gaskets can be set to improve the stability of the reinforcing bolt 91. In this way, the reinforcing bolt 91 not only serves to connect the flange, connecting plate 2 and base 1, but also triggers the expansion effect of the support 8.

[0034] In a further embodiment, referring to Figure 4 The outer wall of the extension column 72 is also threaded with a locking block 19. The locking block 19 is located above the connecting plate 2. Tightening the locking block 19 makes its lower surface press against the upper surface of the connecting plate 2, thereby fixing the extension column 72 and the connecting plate 2 relative to each other, preventing the extension column 72 from loosening, and positioning the connecting plate 2.

[0035] Reference Figure 4 A second elastic element 18 is provided between the upper and lower adjacent mounting seats 81. The second elastic element 18 is a spring, which is used to keep each mounting seat 81 at a certain distance in the initial state, so that the support 8 naturally forms a frustum shape that is smaller at the top and larger at the bottom, making it easier for the rod to be inserted.

[0036] This embodiment also discloses a method for replacing underground foundations for traffic poles that are easy to replace, including the following steps: S1: Remove all reinforcing bolts 91 and threaded seats 32. The support 8 will automatically retract under the action of the first elastic element 14 and lift the old rod away.

[0037] S2: Based on the bolt hole positions of the new rod flange, move each connecting rod 31 radially along the adjusting groove 4 to the alignment position; by rotating the adjusting rod 13, adjust the initial position of the sliding column 101 so that the initial outer diameter of the support 8 is slightly smaller than the inner diameter of the new rod. S3: Lift the new rod and slowly lower it with its inner cavity aligned with the extension column 72, ensuring that the bolt holes on the rod flange pass through each connecting rod 31 until the lower surface of the flange is in contact with the upper surface of the connecting plate 2. S4: Tighten the threaded seat 32 to press against the upper surface of the flange; tighten the reinforcing bolt 91, its lower end pushes the contact rod 17 downward, causing the sliding column 101 to slide downward, so that the support 8 is pushed outward to press against the inner wall of the new rod; continue to tighten to the predetermined torque; S5: Confirm the verticality of the rods and the firmness and reliability of all connections, and complete the replacement.

[0038] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
