Abstract
The utility model belongs to the bracing or strutting arrangement of nuclear power plant nuclear island district cable crane span structure, is specifically related to a kind of nuclear power station Anti-vibration cable support.It comprises the rack body be made up of many crossbeams and many root posts, rack body is evenly distributed with multiple trailing arm, described each trailing arm is provided with crane span structure, and described trailing arm comprises arm body and is positioned at the mounting base of arm end of body, and described mounting base is arranged on column by U-bolt; Described arm body is combined by C-type steel and the square steel tube being positioned at C-type steel bottom, and described C-type steel is provided with crane span structure by bolt and spring nut.Its shock resistance can be improved after adopting this structure, and be convenient to the height dismantling and regulate trailing arm.
Description
Technical field
The utility model belongs to the bracing or strutting arrangement of nuclear power plant nuclear island district cable crane span structure, is specifically related to a kind of nuclear power station Anti-vibration cable support.
Background technology
nuclear island of nuclear power station cable testing bridge is for all kinds of cable of rest, electric wire, is the vitals ensureing that reactor safety is run.Require that cable testing bridge system can be fulfiled it and support defencive function when earthquake occurs, do not rupture, fall, the changing of the relative positions, the unfavorable phenomenon such as flexure and displacement deformation, the situation such as avoid cable appearance to damage, to break.And cable bearer is the strutting piece of cable testing bridge, must there be good intensity, flexing resistance guarantee himself can the associated load such as load-bearing cable crane span structure and cable.
Bearing capacity, the shock resistance of cable bearer, mainly to restrict by key elements such as support arm structure, material, base plate thickness on cable bearer.Old-fashioned cable bearer trailing arm traditional is at present that C shaped steel or plate folded structure and base plate are welded, and its intensity can not meet shockproof requirements.
The mounting means of existing trailing arm on cable bearer causes its dismounting inconvenient, also not easily regulates height.
Summary of the invention
Technical problem to be solved in the utility model is, provides a kind of nuclear power station Anti-vibration cable support that can meet shockproof requirements.
The technical solution of the utility model is: a kind of nuclear power station Anti-vibration cable support, comprise the rack body be made up of many crossbeams and many root posts, rack body is evenly distributed with multiple trailing arm, described each trailing arm is provided with crane span structure, described trailing arm comprises arm body and is positioned at the mounting base of arm end of body, and described mounting base is arranged on column by securing member; Described arm body is combined by C-type steel and the square steel tube being positioned at C-type steel bottom, and described C-type steel is provided with crane span structure by securing member.
Described mounting base is arranged on column by U-bolt, and the rear portion of described U-bolt encircles on column, front end is arranged in the screwed hole of mounting base by nut.
Described crane span structure is arranged in C-type steel by bolt and spring nut.
Described C-type steel welds together with the square steel tube being positioned at C-type steel bottom.
Be interconnected by brace between described crossbeam and crossbeam.
The utility model has the advantage of: 1. trailing arm is arranged on column and described crane span structure is arranged in C-type steel by bolt and spring nut, contribute to improving shock resistance.
2. trailing arm described in is combined by soldering group by C-type steel and the square steel tube being positioned at C-type steel bottom, and weld seam is long, firm welding.Adopt dimorphism steel construction, compared with traditional single C shaped steel or plate folded structure, enhance the intensity of trailing arm, the area welded with mounting base also becomes large, and welding is more firm, improves shock resistance.
3. mounting base described in is arranged on column by U-bolt, such mounting means, is convenient to the height dismantling and regulate trailing arm.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model;
Fig. 2 is the enlarged drawing of Fig. 1 at I place.
Embodiment
