Abstract
The utility model relates to a protective cover of a lower collection contact rail with unequal sides. The protective cover is arranged above the lower collection contact rail, comprises a top and two side plates, and covers the upside and the two sides of the contact rail; the protective cover is characterized in that: the side plate on the side which is far away from a vehicle is longer than the side plate on the other side. The protective cover of the contact rail disclosed by the utility model is arranged on one side which is impossibly contacted with a collector and also on one side of a people action area; the protective cover is lengthened, so that protection area is increased and personal safety protection is enhanced; meanwhile, the other side is not lengthened, so that matching of the collector of the vehicle with the contact rail is not affected.
Description
Technical field
The utility model belongs to field of track traffic, more specifically, relates to a kind of subway contact rail protective cover.
Background technology
In the prior art, the bottom is awarded the stream contact rail and is provided with protective cover, and contact rail is protected, and the protective cover cross section is similar to and is Ω shape, and its structure has the cover top of a curved surface and the side plate of both sides as shown in Figure 1.The running condition of this protective cover can be referring to China utility model patent ZL 93224173.5, be that contact rail support and trip by the L type forms a cantilever design, this trip be with the cross section " worker " thus the top flange of the contact rail of font mutually blocking be fixed, and protective cover is located at this contact rail top and biside plate covers the contact rail both sides.Again as shown in Figure 1, for guaranteeing that the vehicle pantagraph current collector contacts with the normal of contact rail, the base of contact rail protective cover is higher than the contact surface of contact rail, and the determining of its height mainly considered the abrasion loss of contact rail and in the influence of superelevation section pantagraph current collector to the eccentric wear of contact rail.Therefore protective cover can't guarantee to protect fully to the side of contact.
It is no problem that under normal circumstances the main track that enters nobody adopts this kind protective cover.But in the garage of car depot, service personnel may be movable in the charged scope of contact rail, generally takes the mode of trolley to solve abroad.Because the price of trolley is higher, and inbound/outbound process has some influences to vehicle, and is therefore domestic not widely-used, still adopts contact rail to add the mode of protective cover in a large number.
The utility model content
The purpose of this utility model is to provide a kind of addressing the above problem, and increases the lengthening protective cover of contact rail pretective acreage.
For achieving the above object, the utility model adopts following design plan:
Stream contact rail protective cover is awarded in a kind of scalene bottom, and it is located at the bottom and awards stream contact rail top, has a cover top and two side plates, is covered in the top and the both sides of contact rail, it is characterized in that, and is longer than the side plate of opposite side away from the side plate of vehicle one side.
Aforesaid contact rail protective cover, preferably, the side plate of described length is than the short long 36mm of side plate.
Aforesaid contact rail protective cover, preferably, a side of described long side plate is 175mm by the length that cover pushes up the side plate base, a side of short side plate is 139mm by the length that cover pushes up the side plate base.
Aforesaid contact rail protective cover, preferably, the base of the side plate of described weak point is positioned at 11mm place, contact rail contact surface top.
Aforesaid contact rail protective cover, preferably, the base of the side plate of described length is positioned at 25mm place, contact rail contact surface below.
The beneficial effects of the utility model are:
Contact rail protective cover of the present utility model, it is a side that can not contact at pantagraph current collector, also is a side in personnel activity zone simultaneously, with the protective cover lengthening, can increase pretective acreage, increases the personal safe protection.Opposite side does not extend simultaneously, can not influence the coupling of vehicle pantagraph current collector and contact rail.
Description of drawings
Fig. 1 is the structural representation of prior art protective cover.
Fig. 2 is the structural representation of the utility model protective cover.
The specific embodiment
The utility model provides a kind of scalene bottom to award stream contact rail protective cover, it is located at the bottom and awards stream contact rail top, has a cover top and two side plates, is covered in the top and the both sides of contact rail, it is characterized in that, longer away from the side plate of vehicle one side than the side plate of opposite side.As shown in Figure 1, protective cover 1 of the prior art is 139mm by cover top 3 length to side plate 4 bases, and the base of its biside plate 4 is positioned at the 11mm place, contact surface top of contact rail 2.And as shown in Figure 2, protective cover 1 of the present utility model, a side of its lengthening is 175mm by cover top 3 length to side plate 5 bases, its base than prior art drop-down 36mm, be positioned at the 25mm place, contact surface below of contact rail 2, and the length of opposite side side plate 4 remains unchanged.
Protective cover of the present utility model is that a contact rail support and the trip by a L type forms cantilever design in use, this trip be with the cross section " worker " thus the top flange of the contact rail of font mutually blocking be fixed; Protective cover is located on this contact rail and biside plate covering contact rail both sides.Wherein, a side of protective cover lengthening is positioned at a side in personnel activity zone, can increase pretective acreage, increases the personal safe protection.This side also is simultaneously the side away from vehicle, thereby can not influence the coupling of vehicle pantagraph current collector and contact rail.
The material of protective cover of the present utility model is preferably glass-felt plastic, it in the preparation, be newly-increased a kind of mould on the basis of existing protective cover mould, according to the side lengthening of above-mentioned protective roof structure to this mould, and the employing pultrusion molding process identical with existing protective cover preparation technology is prepared.
Claims (5)
