Abstract
The utility model discloses an overpass bridge for bearing a cable duct in a transformer substation. Openings are arranged at the upper ends of two L-shaped foundations at two sides of a body of a cable duct, a cover plate bridge is arranged above the cable duct by the openings; and the cover plate bridge is made of steel, and a checkered steel plate is arranged on the upper surface of the cover plate bridge. In the overpass bridge of the cable duct for bearing in the transformation substation, as the cover plate bridge is arranged above the cable duct through the openings at the upper ends of the two L-shaped foundations, when an operating vehicle passes through the cable duct, the gravity acts on the cover plate bridge and the two L-shaped foundations instead of a cover plate of the cable duct, so that the problem that the operating vehicles, cranes and other special vehicles span the cable duct in the transformer station is solved, and the operation vehicle can freely span the cable duct so as to enter the operating area, therefore, the work efficiency is greatly improved, and the site construction and the lifting of equipment in the operation area are convenient; and the checkered steel plate on the upper surface of the cover plate bridge enhances the friction force between a wheel and the steel plate so as to play the role of preventing skidding.
Description
Technical field
The utility model relates to a kind of cable trench load carrier, especially a kind of transformer station cable trench load-bearing overpass bridge.
Background technology
Domestic existing transformer station does not consider the current of working vehicle on the cable trench structure design, even the part electric fixtures around all by cable trench around, the cover plate of cable trench is made up of concrete and arrangement of reinforcement, can not bear the weight of working vehicle, cause working vehicle can not by cross over ditch enter by cable trench around the zone in work.The scene can only be adopted and be increased the crane tonnage, by stretching out long crane support working vehicle is hung in the method for operating area, and time duration is long, operate dangerous, influence maintenance construction speed owing to adopted long crane support, has caused inconvenience for the lifting of the equipment in the operating area simultaneously.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of transformer station's cable trench load-bearing overpass bridge simple in structure, solved the problem that special vehicles such as working vehicle, crane are crossed over transformer station's cable trench, make working vehicle freely cross over cable trench and enter the operating area, improve operating efficiency greatly, made things convenient for site operation.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of transformer station cable trench load-bearing overpass bridge, and the upper end, two L type bases of being located at cable trench ditch body both sides is provided with opening, and the cover plate bridge is installed on the cable trench top by opening.
The cover plate bridge is a steel cover plate bridge, and cover plate bridge upper surface is provided with checkered steel plate.
Transformer station's cable trench load-bearing overpass bridge that the utility model provides, because the cover plate bridge is installed on the cable trench top by the opening on the two L type bases, action of gravity was on cover plate bridge and two L type bases when working vehicle passed through cable trench, can not act on the cable channel cover plate, solved the problem that special vehicles such as working vehicle, crane are crossed over transformer station's cable trench, make working vehicle freely cross over cable trench and enter the operating area, improve operating efficiency greatly, made things convenient for the lifting of equipment in site operation and the operating area; The checkered steel plate of cover plate bridge upper surface has increased the frictional force between wheel and steel plate, has played anti-skidding effect.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples:
Fig. 1 is the utility model structural representation.
The specific embodiment
As shown in Figure 1,1, the 1 ' upper end, two L type bases of being located at cable trench ditch body 4 both sides is provided with opening, and cover plate bridge 2 is installed on the cable trench top by opening.
The specific embodiment of the present utility model is as follows:
Make cover plate bridge 2 → on cable trench, select appropriate location and excavate certain depth → build two L type basis 1,1 ' and mounting cover slab bridges 2 in the cable trench both sides as the cable cover plate at position → this place of dismounting of mounting cover slab bridge 2 and with the cable trench both sides.
The bottom on two L type bases 1,1 ' is concordant with concrete cushion 5 bottoms of cable trench, and cover plate bridge 2 upper surfaces are concordant with the cable channel cover plate upper surface on next door.
