Description

Technical Field

[0001] The utility model relates to the technical field of power iron tower construction, in particular to a power iron tower base anchoring device. Background Art

[0002] The power tower, also known as the electric tower, is a trapezoidal or triangular tower-shaped building with a height of usually 25-40 meters and a steel frame structure. Most of the electric towers are built near power plants and distribution stations in the wild. They are important facilities of the power sector, which can overhead wires and play a role in protection and support. The design, manufacture, installation, maintenance and quality inspection of power towers are important guarantees for the operation and development of modern power systems. During the construction of power towers, in order to improve their stability, reinforcement operations will be carried out on the base at the bottom. The reinforcement devices usually used are generally anchor rods and other structures to anchor them. With the development of modern science and technology, there are more and more types of anchoring devices, and the reinforcement effect of the base of the power tower is getting better and better.

[0003] In view of this, Chinese Patent No. CN215255042U proposes an anchoring device for the base of an electric tower, in which a fixing plate is fixed to the base by four bolts, and then the threaded anchor rod is driven to rotate by rotating the fixing plate so that the bottom end of the threaded anchor rod is inserted into the ground. In this way, the base of the electric tower can be anchored to the ground. Compared with opening threaded holes, opening insertion holes is not only fast, but also efficient and time-saving. However, the anchoring device in the above technical solution is a single structure when fixing the base of the electric tower, and has no wrapping effect on its base. In the later stage, as long as one anchor rod is loose, it may affect the supporting effect of the base and cause it to loosen. The additional wrapping structure around the base of the tower will require the production of wrapping structures of more sizes due to the different sizes of each tower base, which increases costs. Therefore, a wrapping anchoring structure with adjustable size is needed. Utility Model Content

[0022] The examples are as follows:

[0023] The utility model provides Figure 1-4 The power tower base anchoring device shown includes four triangular fixing frames 1 and four anchor rods 14, and a wrapping anchoring mechanism with adjustable size is arranged between the four triangular fixing frames 1;

[0024] The size-adjustable wrapping anchoring mechanism includes a card slot 2 opened at both ends of two of the triangular fixing frames 1, and the other two triangular fixing frames 1 are fixed with a card strip 3 at both ends, and the outer walls of the four card strips 3 are respectively connected with the inner walls of the four card slots 2, and a plurality of tooth grooves 4 are opened at equal distances on one side of the two card strips 3, and one end of the two triangular fixing frames 1 is fixed with a card tooth 5 at the edge of the card slot 2, and the outer walls of one end of the two card teeth 5 are respectively connected with the inner walls of two of the tooth grooves 4, and the edge of one side of the bottom of the four triangular fixing frames 1 is fixed with an insertion bracket 6, and the top of the four triangular fixing frames 1 is A first screw hole 7 is provided on one side, and a second screw hole 8 is provided on the other side of the top of each of the four triangular fixing frames 1. Because the tooth grooves 4 and the latch teeth 5 can only move in one direction, and the reverse movement is blocked and restricted by them, the original state between the four triangular fixing frames 1 and the latch strips 3 is that the latch strips 3 are pulled out to the longest distance, showing their maximum size. At the same time, the end of the latch strips 3 is limited so that the triangular fixing frames 1 and the latch strips 3 will not be separated. When wrapping the base of the iron tower, the size is appropriately reduced according to the size of the base, and it cannot be expanded after being reduced. Therefore, when reducing the size of the device, it is necessary to first measure the outer length of the base;

[0025] Furthermore, screw rods 9 are inserted into the inner walls of the four second screw holes 8 , and the outer walls of the four screw rods 9 are respectively threadedly connected to the inner walls of the four second screw holes 8 , and fixing plates 10 are fixed to the top ends of the four screw rods 9 .

[0026] The bottom of the four screw rods 9 are fixed with a fixing cone 11, and the middle position of the top of the four fixing plates 10 is fixed with an outer hexagonal block 12. The outer hexagonal block 12 is arranged on the fixing plate 10 to facilitate the screw rod 9 to be screwed down. At the same time, the fixing plate 10 is fixedly attached to the triangular fixing frame 1 to increase the area in the hand, increase the friction, and thus maintain stability so that the screw rod 9 is not easy to fall off. The fixing cone 11 at the bottom of the screw 9 is facing upward to increase the resistance to pulling up after inserting it into the ground;

[0027] Furthermore, a first rubber gasket 13 is fixedly provided at the top of each of the four triangular fixing frames 1 at the outer edge of each second screw hole 8 , and the bottoms of the four fixing plates 10 are in contact with the tops of the four first rubber gaskets 13 , respectively.

[0028] The outer walls of the four anchor rods 14 are respectively connected to the inner walls of the four first screw holes 7 by insertion, and the outer walls of the four anchor rods 14 are respectively connected to the inner walls of the four first screw holes 7 by threads.

[0029] Limiting grooves 15 are provided on both sides of the inner walls of the four card slots 2, and limiting strips 16 are fixedly provided at the middle positions of both sides of the outer walls of the four card strips 3, and the outer walls of the four limiting strips 16 are respectively connected with the inner walls of the four limiting grooves 15, and the bottoms of the four triangular fixing frames 1 are fixedly provided with second rubber washers 17. By inserting the mounting bracket 6 into the ground and then inserting the anchor rod 14 through its inner wall into the ground, the anchoring device is fixed more firmly, and the triangular fixing frame 1 can maintain a state of tightly fitting around the base after the mounting bracket 6 is inserted into the ground. At the same time, the first rubber washer 13 and the second rubber washer 17 are respectively provided at the top and bottom of the triangular fixing frame 1 to prevent rust from causing rotting and damage to the fixing plate 10 and the triangular fixing frame 1.

[0030] Working principle: When using the power tower base anchoring device in the present design, firstly, the four triangular fixing frames 1 at the upper end of the device need to be connected through the four clips 3 and the clip slots 2 and then docked. When anchoring the power tower base, the four triangular fixing frames 1 are pushed according to their size so that the clips 3 at their upper ends slide with the clip slots 2 to adjust their size. After the adjustment, the clips 5 on two of the triangular fixing frames 1 in different directions are clipped into the tooth grooves 4 on one side of two of the clips 3 to fix them, so that they can only reduce their size but not expand it. Then, they are wrapped around the periphery of the base. The outer wall of the base blocks them so that they cannot reduce their size and can only cling tightly to the surrounding outer wall of the base. At this time, the bracket 6 is inserted Into the surrounding underground to fix it, and screw the anchor rod 14 and the outer hexagonal block 12 so that the anchor rod 14 and the screw rod 9 are inserted into the ground together to reinforce it. At the same time, a fixing cone 11 is provided at the bottom of the screw rod 9. After being inserted into the ground, the upward resistance is increased, making it difficult to detach, reducing the anchoring cost while improving its firmness and the practicability of the device. When the triangular fixing frame 1 is pushed to shrink its size, the card strip 3 slides in the card slot 2 through the limit strip 16 at its upper end and is connected with the limit groove 15 in the card slot 2 to keep it stable and not easy to shake left and right. In the later anchoring and wrapping process, the structure has strong stability and is not easy to loosen the anchoring state due to long-term shaking, thereby improving the fixing effect of the device.
