Description
Technical field
The present invention relates to a kind of firmly curved dog leg processing unit of contact line and method, it is mainly used in electric railway copper and copper
Alloyed contact line it is whole curved.
Background technology
With flourishing for transportation, railway systems are relied on constantly with new science and technology to improve the row of railway
Vehicle speed, strengthen industrial competition.《Mid-long term railway network plan》（2016-2025）It is required that railway construction engineering will combine new line
Build and implement existing railway transformation and expand energy engineering, lift existing road network quality, can change to planning implementation in 2025 both wired expansion
Make 20,000 kms.Due to the electric railway built before the 90's of last century, do not possess Novel machine largely
The condition of vehicle speed increase.Required to reach speed-raising, take and arranged to what existing electrified railway circuit and its equipment were transformed
Apply.The critical component that contact line is powered as contact net, by Existing railway promotion engineering due to unwrapping wire technique and unwrapping wire condition
Influence, unavoidably occur glacing flatness be more than 0.2mm/m hard spot.When locomotive by when, pantograph high-speed cruising passes through this
Abnormal rise occurs in hard spot, pantograph（Or reduce）, there is phenomena such as arcing, have a strong impact on pantograph uses the longevity
, larger potential safety hazard be present in life.It is general to be carried out back and forth with the five whole curved devices of wheel when occurring hard spot or dog leg in construction of railways at present
Regulation, 3mm/m's or so is hard curved, after continuous regulation 3 to 4 as a child, could renovate and arrive 0.4mm/m or so, finally
The 0.2mm/m of examination may not still be reached.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of contact line firmly curved dog leg processing unit regarding to the issue above
And method, improve whole curved efficiency.
Technical scheme is used by the present invention solves the above problems：A kind of firmly curved dog leg processing unit of contact line, including
Hydraulic pump, brace, hydraulic oil pipe, plunger and mould, wherein mould are divided into upper die and lower die, and the upper mould is fixed by connector
On plunger, the lower mould is socketed with plunger, can be moved up and down with plunger；The brace is arranged on hydraulic pump, the liquid
Press pump is charged hydraulic pump, connects hydraulic oil pipe thereon, and plunger is driven by hydraulic oil pipe fuel feeding.
Positive stop is set at left and right sides of the upper mould, for limiting the movement of lower mould.
The hydraulic pump is charged hydraulic pump.
A kind of firmly curved dog leg processing method of contact line, operation trolley is placed on rail, operating personnel climbs up hand push
Car, charged hydraulic pump is backed on the body using brace.Mould release is opened, and the contact line for having hard spot is placed in a mold, then
Mould is closed.After opening charged hydraulic pumping source switch, hydraulic circuit driving stretches out plunger upwards, under plunger socket
Mould moves up, and heads on hard curved contact line, until it is bonded completely with upper mould, change is in line, and completes whole curved.Once into
Type, time only need several seconds, it is whole it is curved after the performance of contact line be not affected.
The advantage of the invention is that：
The present invention, power is provided with rechargeable hydraulic pump, is conveniently carried out in the wild whole curved；Hydraulic pump powerful simultaneously,
Whole curved significant effect, operating efficiency are greatly improved.
Brief description of the drawings
