Abstract
The invention provides an upper perpendicular tee joint. Convergence and divergence effects on cables in the perpendicular direction can be achieved by reasonably installing the upper perpendicular tee joint in a proper position of a bridge body. The upper perpendicular tee joint comprises a tee joint body, a first cable inlet, a second cable inlet, a perpendicular cable inlet, transverse heat dissipating holes, longitudinal heat dissipating holes, tee joint extensions, a tee joint cover plate and extension inserting grooves. The upper perpendicular tee joint is characterized in that the first cable inlet and the second cable inlet are arranged on the two sides of the tee joint body respectively, and the longitudinal heat dissipating holes are formed in the two sides of the tee joint body respectively. Cables on the two sides of the bridge body are made to converge at one position and be perpendicular downward by reasonably installing the upper perpendicular tee joint in a matched mode, the convergence and divergence effects on lines can be achieved for the bridge body, and multi-branch support can be provided for the bridge body; the tee joint body and the tee joint cover plate are both supported by plates of fireproof and flameproof material, and thus the safety of the whole bridge body is improved; damage to the cables inside the tee joint body is reduced due to the fact that plastic paint is sprayed onto the inner wall.
Description
Technical field
The present invention relates to cable testing bridge field, relate in particular to a kind of vertical threeway.
Background technique
Crane span structure is the equipment of setting up electric wire of often using during electrical engineering is installed.Crane span structure be by the straightway of pallet, ladder, curved logical, annex and, suspension bracket forms, in order to the continuous general name with rigid construction system of carrying cable.Cable testing bridge is to make electric wire, cable, umbilical lay main road standardization, systematize, unitized communication paving device.Crane span structure is used for laying power cable and control cable, is used for away cable and pipeline.
Summary of the invention
The problem to be solved in the present invention is to provide a kind of vertical threeway, solves interflow and the diffusing effect of Vertical direction cable by reasonable installation in the appropriate position of crane span structure main body, and inwall plastic-blasting of the present invention guarantees that inner antirust, insulation extends physical life.
Technical solution of the present invention is as follows: a kind of vertical threeway, comprises threeway main body, the first cable entrance, the second cable entrance, vertical cables entrance, heatsink transverse hole, longitudinal radiation hole, threeway extension, threeway cover plate and extension slot.It is characterized in that described threeway main body both sides are provided with the first cable entrance, the second cable entrance and longitudinal radiation hole, described threeway main body below is provided with vertical cables entrance and heatsink transverse hole, described threeway main body top is provided with threeway extension, and described threeway cover plate below is provided with extension slot.
Further, described vertical threeway is applied fireproofing plate.
Further, described threeway main body inner wall plastic-blasting.
Further, the first cable entrance of described threeway main body, the second cable entrance, vertical cables entrance are square.
Further, described heatsink transverse hole and longitudinal radiation hole two ends are rounding.
Beneficial effect of the present invention is: thereby by the upper reasonably combined installation of vertical threeway of basis is pooled to a place vertically downward by crane span structure main body both sides cable, for having solved circuit, crane span structure main body disperses and congregational rate, for providing many, crane span structure main body supports along separate routes, and threeway main body comprises that cover plate all adopts applied fireproofing plate to support the Security that has increased whole crane span structure main body, and inwall plastic-blasting makes cable reduce damage in threeway body interior.

Fig. 2 is cover plate structure schematic diagram of the present invention.
Wherein: 1, threeway main body, 2, vertical cables entrance, the 3, first cable entrance,
4, the second cable entrance, 5, heatsink transverse hole, 6, longitudinal radiation hole,
7, threeway extension, 8, threeway cover plate, 801, extension slot.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is made to brief description.
As shown in Figure 1, 2, a kind of vertical threeway, comprises threeway main body 1, the first cable entrance 3, the second cable entrance 4, vertical cables entrance 2, heatsink transverse hole 5, longitudinal radiation hole 6, threeway extension 7, threeway cover plate 8 and extension slot 801.It is characterized in that described threeway main body 1 both sides are provided with the first cable entrance 3, the second cable entrance 4 and longitudinal radiation hole 6, described threeway main body 1 below is provided with vertical cables entrance 2 and heatsink transverse hole 5, described threeway main body 1 top is provided with threeway extension 7, and described threeway cover plate 8 belows are provided with extension slot 801.
Connection function: as the medium tache of a three-dimensional crane span structure main body, very important effect has been brought into play in upper vertical threeway, from connecting both sides circuit that it has solved three-dimensional crane span structure, be pooled to a problem vertically downward, directly objectively reflect can not lacking of its effect, its inwall plastic-blasting has improved durability degree, and threeway main body comprises that cover plate all adopts applied fireproofing plate to support the Security that has increased whole crane span structure main body, has increased rationality of the present invention.
Above one embodiment of the present of invention are had been described in detail, but described content is only preferred embodiment of the present invention, can not be considered to for limiting practical range of the present invention.All equalization variations of doing according to the present patent application scope and improvement etc., within all should still belonging to patent covering scope of the present invention.
