Abstract
The utility model discloses a contact-net steel column, belonging to the technical field of railway steel structure member, which is characterized in that: the utility model comprises an H-type profile steel post; a plurality of through holes is opened on the post; a hot dip galvanized layer is arranged on the outer surface of the post; an electrostatic spraying layer is coated outside the hot dip galvanized layer. Compared with the prior art and coating the electrostatic spraying layer outside the hot dip galvanized layer, the utility model has the advantages of effective steel column corrosion resistance to acid and alkali, greatly prolonged service life of steel column, reduced maintenance cost and application to places with serious corrosion such as the coastal area.
Description
Technical field
The utility model belongs to railway steel structure member technical field, relates in particular to the contact system steel column that uses in a kind of electrified railway.
Background technology
Be accompanied by rapid economy development, swift and violent as the transportation construction development of economic lifeline, the electrified railway of convenient and efficient is widely used especially.Catenary mast develops into steel strut by original concrete pillar as the important equipment of electrified railway.This contact system steel column mainly is made of the H type shaped steel cylinder that has base, has some through holes to hang circuit on cylinder, is provided with hot galvanized layer with corrosion prevention at cartridge outer surface.This steel column is simple owing to production technology, being convenient to construct is used widely, but in coastal area of waiting corrosive property severity, is difficult to reach antisepsis only according to hot galvanized layer.
The utility model content
Problem to be solved in the utility model just provides a kind of coastal high contact system steel column of resistance to corrosion that waits the area use of corrosive property severity that is suitable for.
For addressing the above problem, the technical solution adopted in the utility model is: comprise the H type shaped steel cylinder that has base, have some through holes on the cylinder, cartridge outer surface is provided with hot galvanized layer, and the outside of described hot galvanized layer is coated with the electrostatic plastic spraying layer.
Its additional technical feature is: described base is provided with the reinforced rib that is connected with cylinder.
Contact system steel column provided by the utility model compared with prior art, sprayed the electrostatic plastic spraying layer in the outside of hot galvanized layer, thereby the energy actv. prevents the corrosion of acid-base pair steel column, prolong the service life of steel column greatly, reduce maintenance cost, be suitable for the coastal area of corrosive property severity of waiting and use.And the reinforced rib that is connected with cylinder is set on the base, then can make cylinder more firm.
Description of drawings
Fig. 1 is the structural representation of the utility model contact system steel column;
Fig. 2 is the birds-eye view of contact system steel column.
The specific embodiment
Be described in further details below in conjunction with the structure and the use principle of accompanying drawing the utility model contact system steel column.
As shown in Figure 1, the utility model contact system steel column comprises the cylinder 2 that has base 1, and base 1 is provided with the reinforced rib 3 that is connected with cylinder 2, has some through holes 4 on the cylinder 2.As shown in Figure 2, cylinder 2 is a H type shaped steel, and cylinder 2 outside faces are provided with hot galvanized layer 5, and the outside of hot galvanized layer 5 is coated with electrostatic plastic spraying layer 6.
During use, base 1 is fixed on the railway basis, then circuit is suspended on through hole 4 places and gets final product.Hot galvanized layer 5 and electrostatic plastic spraying layer 6 can play a protective role to cylinder 2, thereby prolong the service life of contact system steel column, reduce maintenance cost.
Claims (2)
1. the contact system steel column comprises the H type shaped steel cylinder that has base, has some through holes on the cylinder, and cartridge outer surface is provided with hot galvanized layer, it is characterized in that: the outside of described hot galvanized layer is coated with the electrostatic plastic spraying layer.
2. contact system steel column according to claim 1 is characterized in that: described base is provided with the reinforced rib that is connected with cylinder.
