Abstract
The utility model discloses a universal insulating support steel base for bottom current collection of DC750V contact rails, which comprises a seat frame. The right bottom end of the seat frame is provided with screw holes, and a cover plate provided with screw holes is arranged on the left of the seat frame. The screw holes at the right bottom end of the seat frame are fixed onto a ballast bed through bolts, an insulating support is mounted on a steel base through the screw holes on the cover plate, and a contact rail is fixed onto the insulating support through a clamping jaw of the insulating support, so that contact current collection is realized. The universal insulating support steel base is simple in structure and can be mounted on different ballast beds to realize connection of the insulating support with the ballast beds. Using the universal insulating support steel base can organically connect the insulating support with the ballast bed, reduce types of insulating supports in rail lines, facilitate manufacturing, maintenance and replacement of insulating supports and reduce corresponding cost.
Description
Technical field
The utility model relates to base, and the insulating support steel base is flowed in concrete a kind of universal DC750V contact rail bottom.
Background technology
The insulating support steel base is the connection steel construction piece that is used between contact rail insulating support and the railway roadbed.Because easy damage of insulating support and tenure of use generally about 15 years, need periodic replacement, for ease of the requirement of operation maintenance, general no more than two kinds of the insulating support type of on a circuit, using.In addition; Because ballast bed structure is various informative, can be divided into underground solid bed, overhead support rail platform railway roadbed, the roadbed section is ballast bed, car depot is ballast bed etc., through the adjusting of insulating support steel base type; Can reduce the type of insulating support, so that maintenance, replacing in the future.Like domestic several the track circuits with unified insulating support type, the used cost of the buying of its insulating support, maintenance and replacing all has reduction in various degree.
But, receiving under the stream mode in present DC750V contact rail bottom, there are inferior positions such as version is many, design cycle length, standard disunity in the insulating support steel base.Specific as follows:
1) version is many
Domestic subway receives under the stream mode in DC750V contact rail bottom, and the insulating support steel base is almost all inconsistent in the version of every circuit, does not have commonality.
2) design cycle is long
Every track circuit all will carry out the design of insulating support steel base again, has reduced efficiency.
3) standard disunity
The standard that temporarily neither one can reference comprises material, version etc.
Because the difference of insulating support steel base causes used insulating support type different, for buying, maintenance and the replacing of insulating support brings many inconvenience.
Summary of the invention
The utility model purpose is to overcome the deficiency of above-mentioned prior art and provides a kind of universal DC750V contact rail bottom to be flowed the insulating support steel base, and this understructure is simple, can stably insulating support be connected with railway roadbed.
Realize that the technical scheme that the utility model purpose adopts is: the insulating support steel base is flowed in a kind of universal DC750V contact rail bottom; Comprise mounting; The bottom on said mounting the right offers screw, and the top of said mounting is provided with cover plate, offers screw on the said cover plate.
More excellent, being provided with connecting panel between the right of said mounting and the left side, this connecting panel becomes hexagonal angle with mounting the right.
Further, the right of said connecting panel and mounting and the left side are welded as a whole.
In above-mentioned technical scheme, the screw of the bottom on said mounting the right is at least two, is distributed in the axis both sides of base along the contact rail direction.
In above-mentioned technical scheme, the screw on the said cover plate is at least four, is distributed on the cover plate axis both sides along the contact rail direction symmetrically.
Further, the screw on the said cover plate is positioned at the both sides or the centre of cover plate.
The screw of bottom, the utility model mounting the right is through being bolted on the railway roadbed, and insulating support is installed on the steel base through the screw on the utility model cover plate, and the contact track is fixed on the insulating support through the insulating support claw, realizes that contact is flowed.The utility model is simple in structure, can be installed on the different railway roadbeds, and the realization insulating support is connected with railway roadbed.Use the utility model, organically connected insulating support and railway roadbed, reduced the type of insulating support in the track circuit, make things convenient for making, maintenance and the replacing of insulating support, reduced corresponding cost.

The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is further described.
As shown in Figure 1, the insulating support steel base is flowed in universal DC750V contact rail bottom, comprises mounting 1, and the bottom on said mounting 1 the right offers screw, and the upper end on the left side of said mounting is provided with cover plate 2, offers screw on the said cover plate.In the present embodiment, the bottom on mounting the right offer four screws 7,8,9,10, be distributed in the axis both sides of base symmetrically along the contact rail direction.Offer four screws 3,4,5,6 on the cover plate 2, be distributed on the cover plate 2 axis both sides symmetrically along the contact rail direction.Cover plate 2 welding of present embodiment and the upper end on mounting 1 left side.
When using the utility model; Four screws 7,8,9,10 of bottom, mounting 1 the right are through being bolted on the railway roadbed; Insulating support is installed on the steel base through the screw on the cover plate 23,4,5,6, and the contact track is fixed on the insulating support through the insulating support claw, realizes that contact is flowed.The utility model has organically connected insulating support and railway roadbed, has reduced the type of insulating support in the track circuit.
In order to be applicable to dissimilar railway roadbeds; The another kind of structure of the utility model is as shown in Figure 2; On embodiment 1 described steel base basis, be provided with connecting panel 11 between the right 2-1 of mounting 1 and the left side 2-2, this connecting panel becomes hexagonal angle with mounting the right; It is straggly to be that the right 2-1 and the left side 2-2 of mounting 1 forms, and is positioned at different plane.Connecting panel 11 in the present embodiment is one with the right 2-1 and the left side 2-2 of mounting 1 through being welded to connect.
The use of the utility model is the same with embodiment 1, connects through screw insulating support and railway roadbed are connected as one.
The screw of the bottom on mounting 1 the right all describes with four screws 7,8,9,10 in the present embodiment, and in order better the utility model to be connected with railway roadbed, the screw of the bottom on mounting 1 the right can be made as different quantity and shape according to the needs of environment.
