Description
Technical field
Railway tunnel facility technology field is the utility model is related to, is related specifically to conduit in a kind of tunnel.
Background technology
Contact net is the high voltage transmission line for taking stream for pantograph in electric railway, and it is responsible for handle from traction power transformation
The electric energy obtained is delivered directly to the vital task that electric locomotive uses, therefore the quality of contact net and working condition will be direct
Affect the transport capacity of electric railway.The installation positioning of overhead contact built-in conduit is very important pass during constructing tunnel
One of key process, pre-buried channel flow is difficult to remedy after tunnel-liner installation, and maintenance cost is higher, the peace of pre-buried channel flow
Dress effect directly affects the operation situation of later stage railway.
Well in advance conduit when conduit has tunnel wall shaping in railway tunnel at present, but without special product and standard
Formulate this type products so that although conduit is all arc, installation site and corresponding fixture are all different, therefore
Many problems are run into when installation, many accessories can only be disposable, cannot be continuing with, make after the conduit renewed
Into great waste.
The content of the invention
Technical problem to be solved in the utility model is the defects of overcoming prior art, there is provided a kind of simple in construction, energy
Different conduit installation requirements is enough adapted to, easy for installation, cost is low, and not waste of materials, in the tunnel that may be reused
Conduit.
To achieve these goals, the utility model uses following technical scheme：
Conduit in a kind of tunnel, it is characterised in that include the steel pipe of an arc, the section of steel pipe is square, steel pipe
The centre of lower surface hollows out the mounting groove for being provided with strip；Described steel pipe upper surface is provided with the mounting bracket of left, center, right three,
The mounting bracket on wherein the right is fixedly welded on steel pipe, and middle and the left side mounting bracket is bascule；Described centre and a left side
The mounting bracket on side includes the installing plate of a rectangle, and installing plate lower surface is provided with two blocks of steel plates vertical with installing plate, steel
Spacing is remained between plate, the size of spacing is equal to the width of steel pipe, and mounting bracket is stuck in the enterprising line slip of steel pipe by spacing；Institute
Two waist round hole are also symmetrically offered above the installing plate stated, are attached for the infrastructure with conduit.
In such scheme, the mounting bracket on described the right is the flat board of one piece of rectangle, and two are also symmetrically arranged with flat board
Individual waist round hole.
In such scheme, described two blocks of steel plates vertical with installing plate are in approximately the same plane, two blocks of steel plates
The spacing retained between clamps steel pipe.
In such scheme, the left end of described mounting groove is got through in the opening position close to steel pipe left end, forms groove, peace
End at the mounting bracket of the extreme position of the right-hand member of tankage on the right.
The utility model is by adopting the above-described technical solution, have the advantages that：
The utility model is simple in construction, can adapt to different conduit installation requirements, and easy for installation, cost is low, and not
It waste of materials, may be reused, improve production efficiency.
Brief description of the drawings
Fig. 1 is the utility model embodiment front view；
Fig. 2 is the utility model embodiment upward view；
In figure：1 steel pipe, 2 mounting grooves, 3 installing plates, 4 steel plates.
Embodiment
In order that content of the present utility model is readily apparent understood, below according to specific embodiment and combine attached
Figure, is described in further detail to the utility model.
The conduit in tunnel as shown in Fig. 1 Fig. 2, includes the steel pipe 1 of an arc, and the section of steel pipe 1 is square, steel pipe 1
The centre of lower surface hollows out the mounting groove 2 for being provided with strip；The described upper surface of steel pipe 1 is provided with the installation of left, center, right three
Frame, wherein the mounting bracket on the right is fixedly welded on steel pipe 1, middle and the left side mounting bracket is bascule；Described centre
Include the installing plate 3 of a rectangle with the mounting bracket on the left side, the lower surface of installing plate 3 is provided with two blocks of steel vertical with installing plate
Plate 4, remains with spacing between steel plate 4, and the size of spacing is equal to the width of steel pipe 1, and it is enterprising that mounting bracket by spacing is stuck in steel pipe 1
Line slip；Described installing plate 3 also symmetrically offers two waist round hole above, is attached for the infrastructure with conduit.
In the present embodiment, the mounting bracket on described the right is the flat board of one piece of rectangle, and two are also symmetrically arranged with flat board
Individual waist round hole.
In the present embodiment, the described two blocks steel plates 4 vertical with installing plate are in approximately the same plane, two blocks of steel plates 4
The spacing retained between clamps steel pipe 1.
In the present embodiment, the left end of described mounting groove 2 is got through in the opening position close to the left end of steel pipe 1, forms groove,
End at the mounting bracket of the extreme position of the right-hand member of mounting groove 2 on the right.
Particular embodiments described above, technical problem, technical scheme and the beneficial effect solved to the utility model are entered
Further description is gone, should be understood that and the foregoing is only specific embodiment of the utility model, and do not have to
