Description

A kind of high-voltage transmission line towers steel pole with foot rest
Technical field
The utility model relates to the used steel pole of high voltage iron tower of a kind of power construction field setting up ultra-high-voltage power line.
Background technology
In transmission line of electricity, ultra high-tension transmission line need to set up with high voltage iron tower, high voltage iron tower generally is four angle suspension towers that vertically assembled by some steel poles by four groups, also connects into trussed construction with channel-section steel or angle steel between the steel pole of the setting that each group is serially connected.The two ends of steel pole are provided with the flange that connects two steel poles, the position of truss frame for connecting angle steel is welded with installing rack on the sidewall of steel pole, installing rack is one to be buckled in the grooved steel plate on the steel pole wall, and the grooved steel plate front of installing rack arranges bolt hole, is used for the trussmembers such as connecting angle.When setting up the higher heavier members such as high voltage iron tower, need to the members such as steel pole be lifted to hoist and traction machine the top of the steel pole of having holded up.Need to assemble the unsettled pole that arranges in top of four groups of steel poles holding up in the lifting process, the top of pole arranges pulley, and the hoist and traction machine setting also arranges a traction pulley on the ground on the ground of the centre of four groups of steel towers.The wire rope of the members such as lifting steel pole passes from the pulley on pole top, one end is connected on the steel pole of ground preparation lifting, then the pulley that the other end passes traction usefulness on the ground, four groups of steel tower centers is connected on the hoist and traction machine, hoist and traction machine is lifted to the top of pole by the pulling wire rope with members such as steel poles, thus install be connected to holded up top.
Two ends at steel pole all are welded with flange, and the connection between two steel poles mainly is by bolt two flange to be connected as one.Steel pole is constantly to rock in the lifting process, the flange of the steel pole of lifting wants to align with flange and the bolt hole of already installed steel pole, it is not a nothing the matter, so need the constructor to stand in the upper end of already installed steel pole in the hoisting process, need to be by manually connecting by flange being positioned at two upper and lower steel poles, the lower end flange of the steel pole of lifting and flange and the bolt hole of bolt hole and already installed steel pole are aligned.But, on the general steel pole except the installing rack of the flange that connects steel pole and truss frame for connecting angle steel, other parts of not standing for the constructor.The constructor is when assembling steel pole and trussmember thereof, generally can only be suspended on the steel pole by safety rope, every steel pole is all very thick simultaneously, climbers etc. are stepped on the bar instrument and can not be used, and the constructor underfooting does not have origin of force, make like this constructor's activity be subject to very large restriction, work progress is very difficult, and also danger close is also very inconvenient during loading and unloading, causes easily the generation of construction accident.
The utility model content
The utility model technical issues that need to address provide a kind of steel tower steel pole of ultra-high-tension power transmission line of constructability personnel work.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of high-voltage transmission line towers steel pole with foot rest, comprise the body of rod, be arranged on body of rod two ends flange, be welded on the installing rack that the steel pole truss be used for to be installed on the body of rod outer wall, be provided with foot rest by installing rack on the described body of rod wall, the cross section of described foot rest is several fonts, and foot rest is articulated in the installing rack by the hook of several fonts of foot rest.
The further improvement of the utility model concrete structure is: the arranged outside that described foot rest is relative with hook has the baffle plate that is upturned.
The further improvement of the utility model concrete structure is: be provided with the bolt hole that the cross-under bolt that cooperates with bolt hole on the installing rack is used on the inboard and hook of described foot rest.
The further improvement of the utility model concrete structure is: be provided with the optical cable future part frame on the installing rack on the described body of rod sidewall.
Owing to adopted technique scheme, the obtained technological progress of the utility model is: high-pressure tower of the present utility model is mainly used in the steel tower steel pole of power construction field setting up ultra-high-voltage power line with steel pole, to load onto in advance the parts such as foot rest at steel pole, thereby solve the difficult problem that the high voltage iron tower steel pole is difficult to assemble in the construction assembling process, for the staff provides larger action space, in assembling steel pole process, the constructor can be with foot rest as origin of force, the work progress safety and stability has been accelerated construction speed greatly.
Being provided with the baffle plate that is upturned on the foot rest can prevent from stepping on sky or skidding.With bolt the installing rack cross-under of foot rest and steel pole is got up, can further increase the safety that foot rest hangs.Foot rest is to be hooked on the installing rack, and it can be dismantled at any time, conveniently uses and moves.The optical cable future part frame that arranges on the installing rack provides the installation site of reservation not only for the installation of optical cable, and can play the foot-operated effect of supporting.
