Abstract
The utility model discloses a rust prevention device for a foundation bolt of a steel tube tower, which comprises the foundation bolt and fixing nuts. The two fixing nuts are mounted at one end of the foundation bolt, an annular sealing rubber cushion is disposed between the two fixing nuts, a rust prevention cap is mounted at the other end of the foundation bolt, and annular sealing cushions are arranged among the rust prevention cap and the fixing nuts. The rust prevention device reduces risks that the foundation bolt directly contacts with external environments and gas, reduces probability of rusting of bolt threads, and improves perfectness ratio and health degree of equipment.
Description
Technical field
The utility model belongs to the transmission line equipment technical field, especially relates to a kind of steel tube tower anchor bolt Rustproofing apparatus.
Background technique
Along with deepening continuously of nationwide integrated power grid transformation, the not raising of county town grid equipment quality, steel tube tower is firm owing to having, corrosion-resistant, stable, maintenance is little etc., and advantage is widely used in the grid power transmission circuit.Existing 10KV steel tube tower structure as shown in Figure 1, the steel tube tower bottom stud structure as shown in Figure 2, stratum 4 excavation back cast concrete concrete pedestals 3, anchor bolt 5 places in the concrete pedestal, steel tube tower 1 and anchor bolt 5 socket connections, anchor bolt exposes to outside the footing 2, adopts hold-doun nut 6a, hold-doun nut 6b to compress.But anchor bolt exposed parts length is longer, stands wind and weather, oxidation all the year round, and screw thread gets rusty seriously, and equipment availability and health degree are had a greatly reduced quality; And because the corrosion of bolt screw thread is serious, nut dismounting difficulty, thus steel tube tower needs displacement, when removing, even need employ large-scale cutting, gas welding device, not only lose time, human and material resources and financial resources, also increased power off time, directly influenced the economic benefit of power supply enterprise.
Summary of the invention
For addressing the above problem, the purpose of this utility model provides a kind of simple in structure, steel tube tower anchor bolt Rustproofing apparatus that using effect is good, can stop anchor bolt and directly contact, reduce bolt screw thread corrosion risk, improve the serviceability rate and the health degree of equipment with outside air.
For achieving the above object, the utility model adopts following technological scheme:
A kind of steel tube tower anchor bolt Rustproofing apparatus, it comprises anchor bolt and hold-doun nut, two hold-doun nuts are installed in anchor bolt one end, between two hold-doun nuts the ring packing rubber cushion are arranged; One anti-rust cap is installed in the anchor bolt the other end, and the ring packing rubber cushion is arranged between anti-rust cap and the hold-doun nut.
Owing to adopt aforesaid technological scheme, the utlity model has following superiority:
This steel tube tower anchor bolt Rustproofing apparatus, its reasonable in design, by installing anti-rust cap and ring packing rubber cushion additional, reduced the risk that anchor bolt and external environment condition, gas directly contact, reduce the probability of bolt screw thread corrosion, improved equipment availability and health degree, also reduced steel tube tower regular maintenance amount when having reduced maintenance cost, for enterprise has saved cost, improved economic benefit.
