Abstract
The utility model relates to the power supply and distribution technical field, in particular to an electric wire cable grid bridge frame used when electric wires and cables are laid. The bridge frame is a flat piece grid body formed by transverse ribs and longitudinal ribs. Each longitudinal rib comprises a linear longitudinal rib and two wave-shaped longitudinal ribs of the outermost side. The flat piece grid body is folded into a groove shape with a U-shaped transverse section. The linear longitudinal ribs are fixed to outer sides of the transverse ribs. End portions of the transverse ribs are provided with the wave-shaped longitudinal ribs which are arranged on the portion between the two adjacent transverse ribs, protrude outside and are parallel to the longitudinal ribs. The electric wire cable grid bridge frame is simple in structure and flexible and convenient to install, and shortens installation time. A grid structure can lower cost, saves materials, and is good in heat-dissipation property. The wave-shaped longitudinal ribs does not extrude the placed electric wires and the cables, and does not cause deformation of the electric wires and the cables, so service life of the electric wires and the cables is effectively prolonged.
Description
Technical field
The utility model relates to for the distribution technique field, used electric wire grid crane span structure during especially a kind of laying wire cable.
Background technique
Crane span structure is the carriage of laying wire cable, as shown in Figure 1, common crane span structure is that steel plate is through bending, be converted into grooved, then electric wire is placed in the groove, adds cover plate in the above again, the crane span structure thermal diffusivity of this structure is relatively poor, the making material that uses is more, has increased cost, has caused the waste of material.
The model utility content
The technical problems to be solved in the utility model is: overcome the deficiency in the prior art, a kind of cable and wire grace grid crane span structure is provided.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of electric wire grid crane span structure, the plain film grid body that described crane span structure is comprised of horizontal bar and vertical muscle, vertical muscle comprises the vertical muscle of lineal shape and the vertical muscle of outermost two waveforms, being converted into cross section by plain film grid body is U-shaped groove shape, the vertical muscle of lineal shape is fixed on the outside of horizontal bar, be provided with the vertical muscle of waveform in the end of horizontal bar, the vertical position of muscle between adjacent horizontal bar of waveform protruded laterally and paralleled with vertical muscle.
Described horizontal bar and vertical muscle are metal wire rod.
Described horizontal bar and vertical muscle are fixedly connected by welding.
The beneficial effects of the utility model are: the utility model is simple in structure, flexible for installation easy, shortened the installation time, grid structure can reduce cost, economical with materials, thermal diffusivity is better, the vertical muscle of waveform can not produce extruding to electric wire, the cable of placing, and can not cause electric wire, distortion of the cable, has effectively prolonged the working life of electric wire and cable.
Description of drawings
Below in conjunction with drawings and embodiments the utility model is further specified.
Fig. 1 is the structural representation of original crane span structure.
Fig. 2 is structural representation of the present utility model.
Fig. 3 is side view of the present utility model.
Among the figure: 1. horizontal bar, 2. vertical muscle, 21. lineal shapes are indulged muscle, and 22. waveforms are indulged muscle.
Embodiment
By reference to the accompanying drawings the utility model is further described now.The schematic representation that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, so it only shows the formation relevant with the utility model.
Electric wire grid crane span structure as shown in Figure 1, the plain film grid body that crane span structure is comprised of horizontal bar 1 and vertical muscle 2, vertical muscle 2 comprises the vertical muscle 21 of lineal shape and the vertical muscle 22 of outermost two waveforms, being converted into cross section by plain film grid body is U-shaped groove shape, the vertical muscle 21 of lineal shape is fixed on the outside of horizontal bar 1, be provided with the vertical muscle 22 of waveform in the end of horizontal bar 1, the vertical position of muscle 22 between adjacent horizontal bar 1 of waveform protruded laterally and paralleled with vertical muscle 2, and horizontal bar 1 is fixedly connected by welding with vertical muscle 2.
Horizontal bar 1 is metal wire rod with vertical muscle 2.
The utility model is compared with original crane span structure among Fig. 1, and weight only is 1/3rd of original crane span structure, has reduced cost of material, and the structure of grid is so that install easier, easier when circuit is overhauled, quicker.
When crane span structure is transported, can make crane span structure keep the shape of plain film grid, plain film grid body being converted into cross section again when needing is U-shaped groove shape, and it is just passable that cable or wire is directly put into groove.
The mesh spacing of crane span structure is wide * length=50mm ± 2 * 100mm ± 2, can also adjust spacing according to actual needs.
Above-mentioned mode of execution only is explanation technical conceive of the present utility model and characteristics; its purpose is to allow the personage that is familiar with technique can understand content of the present utility model and is implemented; can not limit protection domain of the present utility model with this; all equivalences of doing according to the utility model Spirit Essence change or modify, and all should be encompassed in the protection domain of the present utility model.
