Description

A kind of insulation bow angle and pantograph thereof

Technical field

This utility model belongs to railway vehicle device, is specifically related to a kind of insulation bow angle and pantograph thereof.

Background technology

The pantograph pan of prior art and Gong Jiao collectively form a frame structure, and this ensures bow delicate structure, and parts are the least possible, easy care.Downward-sloping bow angle, bow two ends can stop pantograph generation drill bow phenomenon.In normal circumstances, contact net moves within the slide plate scope of pantograph.Bow angle requires to firmly install, mustn't have deformation, and must seamlessly transit between slide plate, mustn't transfinite in gap.

Current pantograph bow angle has following defects that

1. bow angle cross section is round tubular, and surface area is big, and in locomotive traveling process, resistance is big.

2. bow angle section matter is mostly metal, and metal bow angle makes pantograph short with the insulation distance of roof, and the probability that roof electrical hazard occurs is big；And metal bow angle often weight is big, has increased the weight of roof stress.

Utility model content

For the problems referred to above, this utility model aims to provide the insulation bow angle and corresponding pantograph thereof that a kind of resistance is little, lightweight, safety is high.

This utility model solves the technical scheme of problem: a kind of insulation bow angle, this bow angle is C font, and described insulation bow angle is flat-shaped streamlined structure, and its cross section is rectangle, and four angles of rectangle are provided with rounding, the upper and lower length of side of rectangular cross section is more than the left and right length of side；The free end at described C font bow angle is interface end.

In such scheme, insulation bow angle is streamlined, is beneficial to contact net and seamlessly transits, has excellent air dynamic behaviour.

Accordingly, this utility model also provides for a kind of pantograph, including the carbon slipper that two parallel interval are arranged, also includes the insulation bow angle described in such scheme, and two interface end at described C font insulation bow angle are connected with the transverse end of carbon slipper respectively；Carbon slipper both lateral sides is respectively connected to an insulation bow angle.

Preferably, the interface end section top at described C font bow angle is circular arc, and oblique angle is cutd open in bottom.Section top is circular arc, it is simple to coordinate installation with bow connecting plate；Bottom is cutd open oblique angle and is conveniently welded with bow connecting plate, is effectively increased bow angle intensity, improves mechanical life.

Further, the upper surface of described carbon slipper is concordant with insulation bow angle upper surface.

Insulation bow angle of the present utility model, has good insulating properties, outside the basic function ensureing common bow angle, has the further advantage that

1. fairshaped bow angular shape design, air drag is little, and is beneficial to contact net and seamlessly transits, and improve structural reliability and the service life at insulation bow angle.

2. bend angle relative to metal, add the insulation distance between roof and pantograph, it is prevented that in the medium such as rainwater, dust, produce flashover, Danger Electric shock risk etc., reduce the probability that roof electrical hazard occurs, increase safety in utilization.

3. insulant is lightweight relative to metal bow angle, and locomotive roof stress is good.

Detailed description of the invention

As shown in figures 1-4, a kind of insulation bow angle 1, this bow angle is C font, and described insulation bow angle 1 is flat-shaped streamlined structure, and its cross section is rectangle, and four angles of rectangle are provided with rounding 5, and the upper and lower length of side of rectangular cross section is more than the left and right length of side；The free end at described C font bow angle is interface end 2.

Such as Fig. 5, this utility model also provides for a kind of pantograph, the insulation bow angle 1 in the carbon slipper 4 arranged including two parallel interval and such scheme, and two interface end 2 at described C font insulation bow angle 1 are connected with the transverse end of carbon slipper 4 respectively.Carbon slipper 4 both lateral sides is respectively connected to an insulation bow angle 1.

The interface end 2 section top at described C font bow angle is circular arc 21, it is simple to coordinate installation with bow connecting plate；Oblique angle 22 is cutd open in section bottom, conveniently welds with bow connecting plate, is effectively increased bow angle intensity, improves mechanical life.

After assembling, the upper surface of carbon slipper 4 is concordant with insulation bow angle 1 upper surface.
