Description

Technical Field

[0001] The utility model relates to the technical field of power tower poles, in particular to a power tower pole foundation device. Background Art

[0002] Power poles, also known as power towers, are tall structures used to support and suspend power lines. They play a crucial role in overhead transmission and distribution lines, primarily maintaining a safe distance between conductors and the ground, buildings, and other objects, ensuring stable and safe power transmission. Power towers can be categorized by material: wood, concrete, and steel. The foundation of a power tower is an underground structure that supports the tower and transmits various loads to the foundation. There are several types of foundations, including direct burial, triple-plate foundations, pile foundations, and extended foundations. Direct burial is suitable for areas with good soil quality; triple-plate foundations enhance pole stability; pile foundations are suitable for soft soil; and extended foundations increase the contact area and are suitable for tower foundations.

[0003] Power towers are composed of several important structures. The pole body (tower body) is the main body. The concrete pole body is generally circular or polygonal. The internal steel bar distribution and concrete strength are configured according to the load-bearing requirements. The tower body is made of steel materials such as angle steel, bolted or welded together to form a stable geometric shape that can withstand and disperse external forces. Crossarms are installed on the top or side of the tower and are used to hang conductors and lightning conductors. Their length and material are determined according to the line conditions. For example, 10kV distribution line concrete poles often use angle steel crossarms, and insulators are installed on them. Insulators insulate the conductors from the tower. There are porcelain, glass, composite and other types, each with its own characteristics. The foundation is the key, transferring the load to the foundation. The type is selected according to the tower and soil quality.

[0004] However, when installing the iron tower in the power pole, the tower is first lifted up by a crane, and then the designated position is found. Then, workers need to use tools such as screwdrivers to insert bolts into the corresponding holes one by one to lock the tower. However, this traditional installation method increases the number of operating steps for workers, and also reduces the installation efficiency to a certain extent, and prolongs the installation time of the entire iron tower. Therefore, a power tower foundation device is proposed to solve the above problems. Utility Model Content

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

A hollow column 9 is slidably connected inside the fixing ring 4. The hollow column 9 is made of carbon structural steel, which has certain strength and toughness and can meet the support and guiding function requirements of the hollow column. A bearing 10 is fixedly connected to the top of the hollow column 9. The bearing 10 is made of high-carbon chromium bearing steel. A clamping block 8 is fixedly connected to the top of the hollow column 9. The clamping block 8 is made of hot-dip galvanized steel. Steel treated with hot-dip galvanizing has good corrosion resistance and can be used for a long time in outdoor environments without being corroded. The side wall of the clamping block 8 is snap-fitted with a fourth fixing column 23. The fourth fixing column 23 is made of hot-dip galvanized steel. The steel material after hot-dip galvanizing has good anti-corrosion performance. The outer wall of the fourth fixing column 23 is fixedly connected to the third fixing column 22. The internal thread of the fourth fixing column 23 is connected to the threaded rod 5. The threaded rod 5 is made of high-strength alloy steel with high strength, toughness and wear resistance. A clamping claw assembly is provided at the bottom of the threaded rod 5, and a support assembly is provided on the inner wall of the fixing ring 4. The clamping claw assembly includes a three-slot column 11. The top of the three-slot column 11 is fixedly connected to the bottom of the threaded rod 5. The inside of the three-slot column 11 is rotatably connected to the second fixing column 13. The outer wall of the second fixing column 13 is rotatably connected to the clamping claw 12. The clamping claw 12 is made of high-strength cast iron, has high strength and toughness, and can withstand a large clamping force. The outer wall of the three-slot column 11 is slidably connected to the inner wall of the hollow column 9;

[0033] Specifically, when using the power tower foundation device, first slowly rotate the third fixing column 22. At this time, the third fixing column 22 will drive the fourth fixing column 23 at one end to rotate after being subjected to force. Since the fourth fixing column 23 is connected to the internal threaded rod 5, when it is rotated under force, it will drive the internal threaded rod 5 to rotate together. At the same time, the fourth fixing column 23 will drive the bearing 10 to rotate during the rotation process. Subsequently, under the action of the movement of the threaded rod 5, the three-slot column 11 will be driven to slide along the inside of the hollow column 9. Then, the movement of the three-slot column 11 will further drive the clamping claw 12 to expand. The clamping claw 12 is limited by the second fixing column 13 so that it is always stably inside the three-slot column 11. Through such a series of actions, the good effect of quickly installing the tower is finally achieved.

[0034] Reference Figure 1 and Figure 3 The top of the tower 1 is fixedly connected with a spire 14. The spire 14 is made of aluminum alloy with the characteristics of light weight and high strength, which can reduce the weight of the spire and ensure its stability in a high-altitude environment. The bottom of the spire 14 is fixedly connected with a first steel cable 15. The first steel cable 15 is made of galvanized steel wire stranded steel wire, which has high tensile strength and good corrosion resistance and can be used for a long time in an outdoor environment. The first steel cable 15 is fixedly connected to the inside of the first connecting ring 16. The bottom of the first connecting ring 16 is fixedly connected with a damping ball 17. The damping ball 17 is made of rubber or elastic polyurethane material, which has good elasticity and damping performance and can effectively absorb To collect and reduce the vibration of the tower under the action of external forces such as strong winds, the bottom of the damping ball 17 is fixedly connected to a fixing plate 18. The material of the fixing plate 18 is carbon structural steel with certain strength and toughness, which can meet the connection and support function requirements of the fixing plate. The outer wall of the fixing plate 18 is fixedly connected to a second connecting ring 19. The inner wall of the second connecting ring 19 is rotatably connected to a third connecting ring 20. The outer wall of the third connecting ring 20 is fixedly connected to a second steel cable 21. The second steel cable 21 is made of a steel strand twisted with galvanized steel wire, which has high tensile strength and good corrosion resistance and can be used for a long time in outdoor environments. One end of the second steel cable 21 is fixedly connected to the inside of the tower 1;

[0035] Specifically, in windy conditions, when the power mast is shaking, the first steel cable 15 is subjected to force and shakes. At this point, the first steel cable 15 is securely fastened to the outer wall of the damping ball 17 via the first connecting ring 16. Simultaneously, the second connecting ring 19, the third connecting ring 20, and the second steel cable 21 closely fit together, further securing it within the tower 1. This design significantly improves the stability of the entire power tower in adverse weather conditions such as high winds, ensuring safe and reliable power transmission and effectively reducing potential safety hazards caused by wind-induced shaking.

[0036] Reference Figure 1 The support assembly includes a tower 1, the outer wall of which is fixedly connected to the inner wall of a fixing ring 4. A crossarm 2 is fixedly connected to the outer wall of the tower 1. The crossarm 2 is made of angle steel and has good structural strength and stability, capable of bearing the weight of the conductors and lightning conductors. An insulator 3 is fixedly connected to the top of the crossarm 2. The insulator 3 is made of ceramic or silicone rubber composite material. Ceramic insulators have good insulation properties and mechanical strength, while silicone rubber composite insulators are lightweight and resistant to pollution flashover. A first fixing column 7 is fixedly connected to the outer wall of the tower 1, and a ladder 6 is fixedly connected to the outer wall of the first fixing column 7.

[0037] Specifically, the firm fixation of the ladder 6 and the first fixed column 7 can provide great convenience for the workers. Workers can move up and down more safely and conveniently, so as to perform maintenance work on the power pole when necessary. Such a design not only ensures the personal safety of workers during the operation, but also improves the efficiency of maintenance work. Then, through the careful setting of the crossarm 2 and the insulator 3, the crossarm 2 plays an important role, mainly used to hang the conductors and lightning conductors to ensure that the power lines can be stably erected in the air. The insulator 3 plays a key insulating effect. It is installed between the crossarm and the conductor, which can effectively insulate the conductor from the pole tower, prevent current from leaking to the pole tower, and ensure the safety and stability of power transmission.

[0038] Working principle: When using the power tower foundation device, first rotate the third fixing column 22. The third fixing column 22 is driven by force to drive the fourth fixing column 23 at one end to rotate. The fourth fixing column 23 drives the internal threaded rod 5 to rotate under the force. At the same time, the fourth fixing column 23 rotates and drives the bearing 10 to rotate. Then, the movement of the threaded rod 5 drives the three-slot column 11 to slide inside the hollow column 9. Then, the movement of the three-slot column 11 drives the clamping claw 12 to expand, and the clamping claw 12 is limited by the second fixing column 13 so that it is inside the three-slot column 11, achieving the effect of being able to The effect of quickly installing the tower is achieved, and then the ladder 6 and the first fixed column 7 are fixed to make it more convenient for workers to move up and down and perform maintenance. Then, through the setting of the crossarm 2 and the insulator 3, it is used to hang the conductors and lightning conductors, and the insulator 3 is used for insulation. Then, in windy weather, under shaking conditions, the first steel cable 15 is forced to shake, and then the first steel cable 15 is fixed to the outer wall of the damping ball 17 through the first connecting ring 16, and is fixed to the inside of the tower 1 through the cooperation between the second connecting ring 19, the third connecting ring 20 and the second steel cable 21, thereby improving stability.
