Technical Field

The utility model belongs to cable and bus duct installation field, it is industrial factory building cable testing bridge and bus duct built on stilts placer specifically.

Background

The existing overhead arrangement mode of large and heavy cable bridges and busway bridges is to arrange triangular supports on wall beams of buildings or door-shaped supports on floor beams.

Some large-scale industrial plants often adopt a form of combining a steel structure and a light plate roof, so that the steel structure is favorable as a main supporting structure, and the steel structure is favorable for supporting the light plate roof. The distance between the roof main beams of the steel structure is larger and exceeds 6 meters. If the traditional door-shaped support is adopted, the distance between two adjacent pairs of door-shaped supports is larger because the door-shaped support needs to be fixed on a main beam of a roof. In the industrial factory buildings, in order to achieve good lighting and ventilation effects, the side wall is generally a glass window, and the cable installation position is far away from the side wall, so that the support cannot root and erect on the side beam. Therefore, other auxiliary brackets cannot be erected between two adjacent door-shaped brackets. When the cable was placed on the great door type support in interval, under the action of gravity, the cable was curved down in the fretwork district of door type support, can't well support the cable, especially to heavy cable, more outstanding.

Detailed Description

The invention will be further described with reference to the following drawings and examples:

an industrial factory building cable bridge and bus duct overhead placement device comprises a cable approach bridge 1, wherein the cable approach bridge 1 is of a planar frame structure, as shown in figure 1; the cable approach bridge 1 is horizontally arranged; along the length extension direction of the cable approach bridge 1, a plurality of upright rods 2 corresponding to the upper roof main beam 4 are arranged on two sides of the cable approach bridge 1, the top ends of the upright rods 2 are connected with the roof main beam 4, and the bottom ends of the upright rods 2 are vertically downward and connected with the cable approach bridge 1; the cable approach bridge 1 and the vertical rods 2 on two sides surround to form a suspension bridge type structure.

The utility model discloses a placer is maked somebody a mere figurehead to industry factory building cable testing bridge and bus duct adopts cable approach bridge 1 to place cable testing bridge and bus duct 5, because cable approach bridge 1 is plane frame construction, compares with an independent cross arm of AND gate type support, and cable approach bridge 1 is more to the strong point of cable, and cable approach bridge 1 links into an integrated entity with all pole settings 2, forms a whole load system, its bearing capacity reinforcing. The installation is more favorable for guaranteeing the flatness of the cable approach bridge 1, and the cable bridge and the bus duct 5 can be better supported.

The utility model discloses, can be used for making somebody a mere figurehead to place the cable testing bridge, can make somebody a mere figurehead to place the bus duct again.

As shown in fig. 3, the roof main beams 4 are generally i-shaped steel beams, the top ends of the vertical rods 2 are welded with connecting plates 21, and the connecting plates 21 are connected with the lower flange plates of the roof main beams 4 through high-strength bolts. The upright rods 2 are made of channel steel or angle steel, so that the strength requirement is met, the weight is lighter than that of other steel sectional materials, and the assembly is convenient.

The cable approach bridge 1 may be a plane truss, but in order to ensure a sufficiently large heat dissipation area, preferably, as shown in fig. 2, the cable approach bridge 1 includes a left frame 11, a right frame 12 and a cross arm 13 which are parallel to each other; a plurality of cross arms 13 are distributed in corresponding areas between two adjacent upright rods 2 on the cable approach bridge 1; one end of the cross arm 13 is fixed on the left frame 11, and the other end is fixed on the right frame 12. This setting encloses into square fretwork district between left side frame 11, right frame 12 and two adjacent cross arms 13, compares with the plane truss of other forms, and the fretwork area is big, more does benefit to the heat dissipation. A plurality of cross arms 13 are distributed in a corresponding area between the cable approach bridge 1 and two adjacent vertical rods 2, so that the supporting points of the cables are more dense along the extending direction of the cables, the downward bending degree of the cables between the adjacent cross arms 13 is relieved, and the supporting performance of the cables is improved.

The left frame 11, the right frame 12 and the cross arm 13 of the cable approach bridge 1 are made of channel steel, so that the cable approach bridge is high in strength and beneficial to assembly.

In order to ensure the balanced stress performance of each position and facilitate the manufacture, a plurality of cross arms 13 are arranged at equal intervals. The equidistant setting of cross arm 13 avoids the length dimension between the fretwork heat dissipation interval inconsistent, leads to along cable length extending direction, and is unbalanced to the built on stilts holding power of cable, appears the too big problem of local kickdown.

Because the interval between the industry factory building roof girder 4 is great, so, an interval for hoisting between the pole setting 2 of cable approach bridge 1 is great, in order to improve the bending resistance of 1 segmental section of cable approach bridge between the adjacent pole setting 2, in order to guarantee to carry out good support to the cable, extension cable approach bridge 1's life, preferred, along 1 length extending direction of cable approach bridge, both sides are provided with respectively in the front and back of each pole setting 2 and share vertical plane with pole setting 2 and draw the

pole

3, 3 one end of draw bar is fixed in pole setting 2, and the other end is fixed in cable approach bridge 1.

Can only set up a set of diagonal draw bar 3 and carry out the tractive, but, in order to further strengthen cable approach bridge 1 and pole setting 2, it is vertical along pole setting 2, be provided with two sets of diagonal draw bars 3 from top to bottom, and two sets of diagonal draw bars 3 are parallel to each other.

Along the length extension direction of the cable access bridge 1, the area of the cable access bridge 1 between two adjacent vertical rods 2 is an access bridge section 1A. Because the middle part of the approach bridge section 1A is a bending-resistant weak area, in order to eliminate the bearing weak point and enable the bearing capacity of each part of the whole cable approach bridge 1 to be more balanced, preferably, the bottom end of the diagonal draw bar 3 positioned above in each approach bridge section 1A extends to the middle part of the approach bridge section 1A.
