The high-seismic-resistance cable holder structurally comprises support arms and a bottom plate connected with end parts of the support arms, wherein the cross section of each support arm adopts a shape formed by two reversed W-shaped structures, and a plurality of triangular cavities are formed. The provided cable holder can keep a stable state and small deflection and has high seismic resistance at the rated load in the seism state; meanwhile, the outsides of the support arms don't have sharp edge structures and are all smooth curved surface and plane structures, so that the cable holder is safer in the filed installation process, and the potential hazard of scratching cables is greatly reduced; and two triangular cavities in the upper-middle part and the lower-middle part of the holder adopt a symmetrical structure, and the upper surface and the lower surface can be used for fixing the bridge, so that the universality is high, and the cable holder is more convenient while compared with an old holder.
Description
Technical field
The utility model belongs to the support device of nuclear power plant's nuclear island district cable crane span structure, is specifically related to the high antidetonation cable bearer of a kind of nuclear island of nuclear power station.
Background technique
The cable testing bridge system is the important product of a class in manufacturing industry, is for the main equipment of standard, protection cable and electric transmission line safety in each infrastructure project.And cable bearer is the important component part in the cable testing bridge system, himself must there be the good intensity, flex resistance guarantee himself can the load-bearing cable crane span structure and the associated load such as cable.
The bearing capacity of cable bearer, shock resistance, mainly restricted by the key elements such as its support arm structure, material, base plate thickness.At present traditional old-fashioned cable bearer trailing arm is that C shaped steel or plate folded structure and base plate are welded.For three generation technique nuclear power station, cable testing bridge and support thereof all should meet the nuclear island shockproof requirements that level and vertical direction seismic acceleration are 0.3g.Old-fashioned trailing arm performance can not meet three generations's nuclear power station shockproof requirements through seismic testing and the software analysis such as PROE, ANSYS.
The model utility content
The purpose of this utility model is to provide the nuclear island of nuclear power station cable bearer of a kind of high strength, high antidetonation, when the nuclear island of nuclear power station zone produces the design basis earthquake accident, guarantee under the fault condition produced at safe shutdown earthquake (SL ?2) that its cable testing bridge system is not damaged, thereby ensure that the nuclear safety relevant cables still can normally move.
The technical solution of the utility model is as follows: the high antidetonation cable bearer of a kind of nuclear island of nuclear power station, comprise trailing arm and the base plate be connected with the end of trailing arm, and the cross section of described trailing arm is two W shape structures that tip upside down on together, forms a plurality of triangular cavities.
Further, the high antidetonation cable bearer of nuclear island of nuclear power station as above, wherein, described trailing arm is welded to form by upper and lower two-part, and every part is for adopting monoblock sheet material to level the structure that the cross section be pressed into is W shape with a roller.
Further, the high antidetonation cable bearer of nuclear island of nuclear power station as above, wherein, the bending part of described trailing arm all is round and smooth curved-surface structure.
Further, the high antidetonation cable bearer of nuclear island of nuclear power station as above, wherein, described trailing arm is up and down, left and right difference symplex structure.
Further, the high antidetonation cable bearer of nuclear island of nuclear power station as above, wherein, described trailing arm end and base plate welding.
The beneficial effects of the utility model are as follows: carry out the mechanics aseismic analysis by adopting the professional softwares such as PROE, ANSYS, under the earthquake state, it is stable that structure provided by the utility model still can keep under load rating, and amount of deformation is very little, has high anti-seismic performance.Simultaneously the trailing arm outside, without the cusped edge structure, is round and smooth curved surface and plane structure, thus safer in installation process at the scene, also greatly reduce the hidden danger that scratches cable.2 triangular cavities in the upper and lower middle part of support are symplex structure, and upper and lower surface all can be used for the fixing of crane span structure, and its versatility is more convenient than old-fashioned support.
The utility model, with respect to traditional cable bearer, has following advantage:
1) trailing arm roller is molded, and work efficiency is high, and its many warp architectures make it aspect self intensity, bearing capacity, be far superior to old-fashioned cable bearer.
2) trailing arm and base plate fusion length are longer, stronger than the flex resistance of old-fashioned cable bearer, pull resistance.
3) the trailing arm cross section of the high antidetonation cable bearer of three generations's nuclear island of nuclear power station is as 2 W structures that tip upside down on together, form a plurality of triangular cavity structures, according to triangle, with other polygonal structures, compare, character with shape invariance, can under larger power effect, can also maintain the original state, so this structure has extremely strong stability, so its high anti-seismic performance of cable bearer is far superior to old-fashioned cable bearer.
4) the high antidetonation cable bearer of three generations's nuclear island of nuclear power station has 16 place's bending structures, and himself intensity also is far superior to old-fashioned cable bearer.
The accompanying drawing explanation
The overall diagram that Fig. 1 is the high antidetonation cable bearer of the utility model three generations nuclear island of nuclear power station;
The cross-section structure that Fig. 2 is the high antidetonation cable bearer of the utility model three generations nuclear island of nuclear power station.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in detail.
As shown in Figure 1, 2, the high antidetonation cable bearer of three generations's nuclear island of nuclear power station of the present utility model, comprise trailing arm 2 and base plate 1, this trailing arm 2 is two W shape structures that tip upside down on together, all adopt monoblock sheet material roller to press and form, then upper and lower two-part back-off welding, the trailing arm cross section is up and down, left and right is symmetrical respectively, its stability is strong, and intensity is high.Sheet material can adopt carbon steel etc. can meet the sheet material of requirement of strength.Base plate 1 adopts the form of welding to link together with the end of trailing arm 2, and the structure of bending strengthens its area of contact, and fusion length is longer than old-fashioned support, has strengthened to a certain extent the intensity of support.
