Please be as depicted in figs. 1 and 2, a kind of contact rail guard 1 provided by the utility model, including contact rail assembly 2,
Contact rail assembly 2 is mounted on 3 side of conductor rail, and contact rail guard 1 is mounted on 2 top of contact rail assembly, conductor rail protection
Device 1 includes shield 12 and mounting assembly 11, and shield 12 is used for the protection of contact, and mounting assembly 11 is used to support and fixes
Shield 12, mounting assembly 11 are fixed on 2 top of contact rail assembly, and mounting assembly 11 is mounted on 12 bottom of shield.
Since shield 12 is supported by mounting assembly 11, shield 12 covers on 3 top of conductor rail, therefore, conductor rail protection
Conductor rail 3 can be effectively protected in device 1, avoid the influence because of bad weather to the power supply system of rail traffic vehicles, Jin Erti
The operational reliability of high orbit vehicular traffic.
In the embodiments of the present invention, shield 12 uses sheet metal structural, and shield 12 is light-weight.Shield 12 is main
It is to implement to protect to it in 3 system head of conductor rail, therefore other than considering surface sleet to the influence of track, also answer
Consider sleet under the transversely acting of wind-force on caused by conductor rail 3 come from the possible influence in oblique upper.In addition, according to existing
The falling speed of raindrop under limiting case and wind speed are carried out Vector modulation, obtained by the vectorial property of scientific conclusion and speed
When the angle of end face of the shield 12 far from conductor rail 3 and conductor rail 3 reaches 40 °, the occlusion area of the anti-skid cover can be kept away
Exempt from contact system under extreme weather is influenced by rain and snow weather.The general curved surface sheet metal structural for using elongated strip shaped, by facing section directly
With the tangent composition of curved sections.It is because the Curvature Effect of curved sections accelerates rainwater in rainwater ice and snow weather using curved sections
The movement speed of ice and snow, to reduce the load-bearing pressure of contact rail guard 1；And it is provided with and is laterally extended in curved sections
Planar section is to come from above in order to prevent or the sleet of oblique upper directly corrodes 3 track of conductor rail.

Ear 111 forms inverted U-shaped structure.Other processes also can be used in the connection of support plate 112 and support trunnion 111, such as:
Welding.Support plate 112 and the support trunnion 111 of its two sides are formed by inverted U-shaped structure, are to be arranged shield 12 and close
Suitable height avoids pantagraph current collector worked to avoid shield 12 and pantagraph current collector metal cap 4 completely in vertical direction
Collision is generated between pantagraph current collector metal cap 4 and contact rail guard 1 in journey, the work for improving contact rail guard 1 can
By property.
Specifically, the second mounting hole 114 connecting with shield 12, the second mounting hole 114 are provided on support plate 112
It is coupled by bolt and nut or other fasteners with the first mounting hole 121, makes shield 12 is firm to be mounted on support plate
On 112.
Further specifically, the second mounting hole 114 is through-hole.
More specifically, the second mounting hole 114 is 4 groups.
In the example of the utility model, loss of weight chamber 113 is provided on support lifting lug, loss of weight chamber 113 can be two band circles
The square hole at angle is also possible to other shapes, and main function is the weight for mitigating entire contact rail guard 1, mentions
The structural soundness of high entire contact rail guard 1.
In the example of the utility model, 111 oral area of support trunnion is provided with the third mounting hole connecting with contact rail assembly
115.Bolt is passed through into the third mounting hole 115 on support trunnion 111, the insulation support device being then passed through in contact rail assembly 2
The 4th mounting hole 211 on 21, it is fixed that finally nut is tightened.
Specifically, third mounting hole 115, the 4th mounting hole 211 are all through-hole
More specifically, third mounting hole 115, the 4th mounting hole 211 are 4 groups.
When needing to install contact rail guard 1, use 4 groups of screw bolt passes for the first mounting hole of kidney slot
121,12 planar section of shield and be provided with 4 groups of through-holes the second mounting hole 114 support plate 112, in support plate 112
Bottom tighten bolt with nut and fix.
Since the insulation support device 21 in contact rail assembly 2 is connected to by fasteners such as bolts the side of track girder,
The lower end surface of the horizontal ribbed support trunnion 111 for 112 two sides of support plate of two of insulation support device 21 provides auxiliary branch
Support.4th mounting hole 211 of third mounting hole 115 and insulation support device 21 on support trunnion 111 is coaxial, passes through bolt etc.
Fastener is attached.
Complete the installation that two above step just completes contact rail guard 1.Contact described in the utility model
Rail guard 1 is other than it can be directed to c-type conductor rail 3 and be installed, it may also be used for I-shaped conductor rail 3 and T-shape rigidity
