Description
Technical Field
The invention relates to the field of power transmission, in particular to a reinforcing device and a reinforcing method for tower feet of an iron tower.
Background
In recent years, with the rapid increase of national economy, the power industry develops rapidly, and the rapid development of the transmission line iron tower industry is promoted. According to statistics, the sales income of the transmission line iron tower industry in China is increased from 50 billion yuan in 2003 to 426 billion yuan in 2010, the annual composite growth rate reaches 36.68%, and the industry is in a rapid development period. Therefore, the demand for the power transmission line tower is also sharply increased. The transmission line iron tower generally comprises the following components according to the shape: wine glass type, cat head type, upper font type, dry font type and barrel type, according to the usage divide into: the tension tower, the straight tower, the corner tower, the transposition tower (the tower for replacing the phase position of the lead), the terminal tower, the crossing tower and the like are structurally characterized in that various tower types belong to a space truss structure, rod pieces mainly comprise single equilateral angle steel or combined angle steel, the materials generally comprise two types of Q235(A3F) and Q345(16Mn), the rod pieces are connected by rough bolts through shearing force by the bolts, the whole tower comprises angle steel, connecting steel plates and bolts, and individual components such as tower feet and the like are welded by a plurality of steel plates to form an assembly, so that hot galvanizing corrosion prevention, transportation, construction and erection are very convenient. For the iron tower with the breath height below 60m, a foot nail is arranged on one main material of the iron tower so as to facilitate the climbing operation of construction operators. The iron tower is generally anchored on the ground, and the conventional iron tower is stable in stress distribution and can meet the requirement of long-time use, but the iron tower is provided with a guyed tower. The guyed tower is a supporting structure for supporting a conducting wire and a lightning conductor by an overhead transmission line, so that the conducting wire meets the distance limiting requirement on the ground and ground objects, and can bear the loads of the conducting wire, the lightning conductor and the guyed tower and the external load. The working of the stay wire iron tower is mainly maintained by stay wires, the stay wires can cause deformation of foundation soil of the ground anchor and the main column and sliding of stay wire parts under the action of external force, and the tension of the stay wires is generally in the process of continuous change due to the influence of temperature change, wind interference and the like. When the tension of the stay wire is increased, the stay wire tower is pulled towards two sides, and various construction joints in the welding process are installed in a matching manner, so that the expansion of the joints is easily caused; when the tension of the stay wire is reduced, the iron tower is less stretched towards two sides, and the iron tower is inwardly contracted. Therefore, in the process of continuous change of the stay wire tension, the load on the iron tower is continuously changed, the failure rate of the stay wire tower can be remarkably accelerated, and the service life of the stay wire tower is short.

The invention is realized by the following technical scheme:
a tower foot reinforcing device for an iron tower comprises a tower body, wherein two I-shaped steels which are parallel to each other are arranged at the bottom of the tower body, flanges on two sides of each I-shaped steel are distributed from top to bottom, webs of the I-shaped steels are vertical, the two I-shaped steels are respectively welded on two opposite sides of the tower body, the two I-shaped steels are distributed along the stringing direction of the tower body, a plurality of first reinforcing rods which are uniformly distributed are fixedly connected between the two I-shaped steels, a horizontal through groove which is positioned on the webs of the I-shaped steels on the two sides is formed between every two adjacent first reinforcing rods, the horizontal through grooves on the I-shaped steels on the two sides are opposite to each other, a plurality of second reinforcing rods are inserted into the two horizontal through grooves which are opposite to each other, two ends; a plurality of sleeves which are uniformly distributed along the long axis of the second reinforcing rod are fixedly sleeved on the second reinforcing rod, two ends of each sleeve are connected with bearings, friction discs are fixedly connected outside the bearings, and the friction discs can rotate around the long axis of the second reinforcing rod under the action of the bearings; the sleeve, the bearings at two ends of the sleeve and the friction discs outside the bearings jointly form a dissipative component, and one friction disc in one dissipative component is in contact with the opposite friction disc in the other dissipative component adjacent to the dissipative component on one second reinforcing rod.
Aiming at the problems that the failure rate is accelerated and the service life is shortened due to the fact that a stay wire tower is interfered by the continuous change of the tension of the stay wire in the prior art, the invention provides a tower foot reinforcing device for an iron tower. The first reinforcing rods are fixedly connected between the two H-shaped steels and are uniformly distributed, the first reinforcing rods are fixedly connected with the H-shaped steels to form a rigid structure, and the length direction of the first reinforcing rods is parallel to the pulling force direction of the stay wire tower, so that the whole rigidity of the bottom of the tower body can be improved through the rigidity of the first reinforcing rods, the bottom of the tower body is difficult to pull and compress, and the whole iron tower has better structural stability through reinforcing the foot part of the tower. The web plate of the I-steel is provided with a horizontal through groove, the horizontal through groove is located between the end portions of two adjacent first reinforcing rods, the horizontal through grooves in the I-steels on two sides are opposite to each other, a plurality of second reinforcing rods are inserted into the two opposite horizontal through grooves, namely, the two ends of each second reinforcing rod are located in the horizontal through grooves in the two I-steels respectively, the contact positions of the second reinforcing rods and the horizontal through grooves are not fixed, and the second reinforcing rods can slide along the horizontal through grooves. All be provided with a plurality of power consumption subassemblies on every second stiffener, a power consumption subassembly includes a sleeve, two bearings and two friction disks, and is specific, the sleeve is along the major axis evenly distributed of second stiffener, and sleeve and second stiffener fixed connection, and the bearing is connected at telescopic both ends, the outer fixed connection friction disk of bearing, therefore the sleeve is fixed, and the friction disk can rotate around the major axis of second stiffener under the bearing effect, and two friction disks of every power consumption subassembly mutually noninterference, and it rotates mutually independent. On a second reinforcing rod, one friction disc in one energy consumption assembly is in contact with the opposite friction disc in the other adjacent energy consumption assembly, namely the adjacent friction discs between the two adjacent energy consumption assemblies are opposite to each other along the length direction of the second reinforcing rod due to the fact that the energy consumption assemblies are arranged adjacently.
