Description
Technical field
The present invention relates to railway transport field, more particularly to a kind of sealing structure.
Background technology
Railway transportation alleviates communications and transportation pressure, now generally uses carbon steel railway transport of passengers road as main means of transport
Line.Wherein, middle low speed carbon steel car undertakes main passenger traffic task with the advantages of cheap, convenient, is passenger traffic main body.It is general on car
Car body pilot beam is provided with, the junction box of car electricity cable-through hole and protection circuit is provided with car body pilot beam, for realizing car electricity
Line arrangement.To ensure that junction box seals with pilot beam postwelding, while enter to reduce external moisture in vehicle operation
Cause to corrode in junction box wire casing, design requirement carries out watering detection to the weld seam between junction box and pilot beam.But due to
The presence of pilot beam cable-through hole, watering can cause current to be flowed into by cable-through hole in junction box when detecting, so as to influence sealing
The accuracy of detection.Therefore, it is necessary to block cable-through hole before watering.
The mode of existing closure cable-through hole mainly has following manner, is sealed, set and cable-through hole shape phase using wooden unit
The wooden unit of matching, wooden unit is arranged in cable-through hole；Existing closure mode can also use block rubber, and rubber is placed in cable-through hole
Blob of viscose, cable-through hole is blocked using the elasticity of block rubber, so as to realize the sealing of cable-through hole.Specifically, using wooden unit sealing
Mode, sharp processing to wooden unit require high, are arranged on due to wooden unit in the space of approximate closing, therefore, the installation of wooden unit and
Dismounting is required for by the way of hammering, and during wooden unit is dismantled, the mode of hammering easily causes to buffer reason block
The deformation of installation region.When sealing is realized by the way of block rubber, because the manufacture of block rubber needs special injection grinding tool
And injection machine, cause production cost high, simultaneously as pilot beam product is steel plate butt welding structure, corner angle be present at cable-through hole
Deng these corner angle may scratch block rubber, cause block rubber to lose sealing function, and recoverability is poor after block rubber damage.
It follows that the mode of existing closure cable-through hole, is whether sealed using wooden unit, or it is close using block rubber
Envelope, all has some limitations.
