Description

Technical Field

[0001] The invention relates to the technical field of self-supporting tower foundations, in particular to a self-supporting tower foundation for a power transmission and transformation iron tower. Background Art

[0002] Self-supporting tower is a type of transmission and transformation tower pole. It supports the transmission and transformation line through its own foundation. Therefore, the stability of the foundation installation determines the stability of the self-supporting tower. At present, the foundation is generally to bury the pile pole underground and then connect the pile pole and the self-supporting tower. This installation method results in low foundation stability and easily causes the self-supporting tower to tilt.

[0003] A Chinese patent discloses a power tower foundation device (authorization announcement number CN211816378U). This patented technology is equipped with a second auxiliary rod and a third auxiliary rod in the base. The movement of the rack drives the auxiliary rod to move and insert into the soil outside the base, thereby improving the stability of the base and the stability of the tower foundation. However, there are some problems. After the auxiliary rods on the left and right sides are moved out and inserted into the soil, there is no positioning function. The auxiliary rods are easily displaced horizontally due to various factors such as soil vibration and move toward the inside of the base, thereby reducing the contact area with the soil layer, which easily affects the stability of the base installation. Therefore, those skilled in the art provide a self-supporting tower foundation for a power transmission and transformation tower to solve the problems raised in the above background technology. Summary of the Invention

The front and rear ends of the connecting rod 11 are rotatably connected to the connecting blocks 12. The two connecting blocks 12 are respectively installed on the inner front and rear side surfaces of the self-supporting tower base 1. A positioning gear 13 is installed at the middle position of the outside of the connecting rod 11. The outside of the connecting rod 11 is located on both sides of the front and rear of the positioning gear 13. An adjusting nut 14 is installed, and an adjusting gear 15 is installed on the outside of the connecting rod 11 on one side of the adjusting nut 14. The adjusting gear 15 is meshed and connected to the adjusting tooth plate 7.

[0026] The self-supporting tower base 1 is installed in the soil layer through the vertical insertion rod 2. The horizontal insertion rod 6 is initially located inside the self-supporting tower base 1. By turning the adjusting nut 14 with a tool, the connecting rod 11 can be driven to rotate, thereby driving the adjusting gear 15 to rotate, and then driving the horizontal insertion rod 6 to extend from the inside of the self-supporting tower base 1 and insert into the soil layer, thereby improving the firmness of the installation of the self-supporting tower base 1 vertically and horizontally. The horizontal insertion rod 6 does not have to be fully extended, and it can be in a state of being nearly fully extended.

[0027] exist Figures 1 to 6 Middle: Two positioning assemblies 16 are symmetrically arranged on the inner lower surface of the self-supporting tower base 1. The positioning assembly 16 includes a positioning seat 18. The positioning seat 18 is installed on the inner lower surface of the self-supporting tower base 1.

The positioning ball 31 is movably connected to the positioning gear 13;

[0028] The initial state of the positioning rod 27 is biased towards verticality, and the initial state of the roller 29 is movably fitted to the upper left end surface of the lifting block 25. When the lifting plate 24 is located at the uppermost part of the installation box 19, the bolt 22 can just be inserted into the installation rod 20; after the horizontal insertion rod 6 is inserted into the soil, the installation rod 20 is rotated to make the lifting plate 24 rise, thereby driving the lifting block 25 to rise through the lifting rod 23, and the positioning rod 27 will rotate clockwise around the hinge block 26, so that the positioning block 30 is stuck in the positioning gear 13, thereby preventing the connecting rod 11 from rotating, and further preventing the horizontal insertion rod 6 from shifting in the left and right directions.

[0029] exist Figure 1 and Figure 7The upper surface of the self-supporting tower flange 4 is located outside the flange fixing bolt 5 and a protective assembly 17 is provided. The protective assembly 17 includes a fixing tank 32, the lower end of the fixing tank 32 is internally threadedly connected to a fixing seat 33, the fixing seat 33 is installed on the upper surface of the self-supporting tower flange 4, and the fixing seat 33 is located outside the flange fixing bolt 5. A first fixing rod 34 is movably connected to the upper surface of the fixing tank 32, two second fixing rods 35 are symmetrically installed on the upper end of the first fixing rod 34, and a threaded rod 36 is installed at the lower end of the first fixing rod 34, the outer surface of the threaded rod 36 is threadedly connected to a threaded block 37, and the threaded block 37 is installed on one side surface of the inner side of the fixing tank 32, the lower end of the threaded rod 36 is rotatably connected to a sealing plate 38, and the sealing plate 38 is slidably connected to the inside of the fixing tank 32, a first sealing gasket 39 is installed on the upper surface of the sealing plate 38, the threaded rod 36 movably passes through the first sealing gasket 39, and a second sealing gasket 40 is installed on the lower surface of the sealing plate 38, and the first sealing gasket 39 and the second sealing gasket 40 are both rubber components;

[0030] The fixing seat 33 is welded to the upper surface of the self-supporting tower flange 4 in advance. After the flange fixing bolt 5 fixes the self-supporting tower flange 4 and the self-supporting tower base 1 together, the fixing tank 32 can be rotatably installed on the outside of the fixing seat 33. Then, the first fixing rod 34 is rotated to drive the sealing plate 38 to descend, thereby driving the second sealing gasket 40 to fit the fixing seat 33. In this way, the flange fixing bolt 5 can be sealed to prevent it from being exposed to the outside for a long time and rusting.

[0031] The working principle of the present invention is as follows: first, the staff needs to install the self-supporting tower base 1 at the position of the self-supporting tower of the power transmission and transformation tower, and first insert the self-supporting tower base 1 into the soil through the vertical plug rod 2, thereby preliminarily completing the fixation of the self-supporting tower base 1; then, the staff uses a tool to clamp the adjusting nut 14 to drive the connecting rod 11 to rotate, and the connecting rod 11 can drive the adjusting gear 15 to rotate. Since the adjusting gear 15 is meshed and connected with the adjusting tooth plate 7, the adjusting tooth plate 7 will drive the horizontal plug rod 6 to move outward, and the horizontal plug rod 6 will be inserted into the soil. The horizontal plug rod 6 does not need to be completely exposed to the outside of the self-supporting tower base 1, so that the positioning ball 31 can jam the positioning gear 13 when the positioning assembly 16 is positioned; in order to avoid the horizontal plug rod 6 from shifting left and right, the staff can manually rotate the installation rod 20, and since the lifting plate 24 is meshed and connected with the installation rod 20, the lifting plate 24 will rise, thereby being driven by the lifting rod 23 When the movable lifting block 25 rises, the left end of the positioning rod 27 will tilt, and the positioning ball 31 will jam the positioning gear 13, and finally the bolt 22 is inserted into the installation rod 20 and the bolt 22 is rotated so that the bolt 22 is threadedly connected to the installation box 19. Since the positioning ball 31 is stuck with the positioning gear 13, the connecting rod 11 will be supported and cannot be rotated, so that the horizontal plug rod 6 will not shift left and right due to soil vibration or any other reason; the staff can then install the power transmission and transformation tower self-supporting tower 3 on the upper end of the self-supporting tower base 1 and fix it tightly with the flange fixing bolt 5, and finally the staff screws the fixing tank 32 to the outside of the fixing seat 33, and then rotates the first fixing rod 34 to drive the sealing plate 38 to descend, driving the second sealing gasket 40 to fit the upper end of the fixing seat 33, which can isolate a large amount of air and moisture, avoid the flange fixing bolt 5 from rusting in a short time, thereby extending the service life.

[0032] The above is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
