Abstract
The utility model relates to a tower cross arm with a handrail. The tower cross arm with the handrail comprises a cross arm body. The handrail is arranged on one side of the cross arm body or handrails are arranged on two sides of the cross arm body, wherein the handrail or the handrails are arranged along the axis direction of the cross arm body. The handrail is installed on the cross arm body through support seats which are angle steel. The inner ends of the support seats are welded on the side face of the cross arm body, and the outer ends of the support seats are connected with the handrail. The handrail is a rectangular structure which is composed of cross rods and vertical rods. The lower ends of the vertical rods are connected with the outer ends of the support seats through bolts. The number of the support seats is three. The support seats are arranged on the side face of the cross arm body and distributed at intervals along the axial direction of the cross arm body. Due to the facts that the advantages of steel pipes are adopted by the cross arm body, wherein the upper side faces of the steel pipes are plane polygons, and the handrail or the handrails are arranged on one side or two sides of the cross arm body, when the tower cross arm with the handrail is in use, a worker can walk on the upper side face of the cross arm body by grabbing the handrail with hands, walk is safe, structure is simple, and personal safety of the worker in construction is ensured. Due to the fact that the handrail and the support seats are connected through the bolts, installation and disassembly are convenient.
Description
Technical field
The utility model belongs to the electric power tower technical field, relates in particular to a kind of safe, simple in structure and the easily cross arm of tower of Armrest is installed.
Background technology
Along with China was to the input increasing of power infrastructures in recent years, increasing transmission line of electricity is set up.Shaft tower because of its compare with traditional angle steel tower have specious, floor space is little, cost performance is high, and adopted by vast Construction unit.Cross arm of tower is the important component part of shaft tower, and it plays the effect of attached cable, and the cross-arm body of cross arm of tower all adopts polygonal steel pipe, such as regular hexagon steel pipe, octagon steel pipe etc.,
In practice of construction, the staff often will climb up cross arm of tower and move the operation of carrying out attached cable along the upper side of cross-arm body, existing cross arm of tower does not mostly have safeguard measure, there is very large potential safety hazard, especially when some highly higher cross arm of tower operations, the security incident such as be easy to occur falling; The cross arm of tower of safeguard measure also occurred being provided with on the market, structure is complicated, the loaded down with trivial details shortcoming of installation but they all exist.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiencies in the prior art, and provides a kind of safe, simple in structure and the easily cross arm of tower of Armrest is installed.
The purpose of this utility model is achieved in that a kind of cross arm of tower of Armrest, comprises the cross-arm body, and a side of described cross-arm body or both sides are provided with along the handrail of cross-arm body axis direction, and handrail is installed on the cross-arm body by bearing.
Described bearing is angle steel, and its inner is welded on the side of cross-arm body, and the outer end is connected with handrail.
The rectangular-shaped structure of described handrail for being made of cross bar and montant, the lower end of the montant of handrail is connected with the outer end of bearing by bolt.
Described bearing is to be arranged on cross-arm body side and along the cross-arm body shaft to three that are equally spaced.
The utlity model has following positive effect: it is the advantage of a plane polygon steel pipe that the utility model has utilized the cross-arm body to adopt upper side, a side or both sides at the cross-arm body arrange handrail, the staff is grabbing handrail with regard to the expert and is walking at cross-arm body upper side so in use, it is safer and simple in structure to walk, and has guaranteed the personal safety of workman when construction; Be bolted between handrail and the bearing, mount and dismount so more convenient.
