Description
Technical field
The utility model is related to a kind of firmly curved dog leg processing units of contact line, are mainly used for electric railway copper and copper closes
Golden contact line it is whole curved.
Background technology
With flourishing for transportation, railway systems rely on improves the row of railway constantly with new science and technology
Vehicle speed enhances industrial competition.《Mid-long term railway network plan》（2016-2025）It is required that railway construction engineering will combine new line
It builds and implements existing railway transformation and expand energy engineering, promote existing road network quality, can change to planning implementation in 2025 both wired expansion
Make 20,000 kilometers or so.Due to the electric railway built before the 90's of last century, do not have Novel machine largely
The condition of vehicle speed increase.In order to reach speed-raising requirement, take and arranged to what existing electrified railway circuit and its equipment were transformed
It applies.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
Hard spot, pantograph will appear abnormal raising（Or it reduces）, there is phenomena such as arcing, seriously affect pantograph uses the longevity
Life, there are larger security risks.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 still be not achieved.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of contact line firmly curved dog leg processing regarding to the issue above
Device improves whole curved efficiency.
The technical scheme in the invention for solving the above technical problem is：A kind of firmly curved dog leg processing unit of contact line,
Including hydraulic pump, shoulder strap, hydraulic oil pipe, plunger and mold, wherein mold is divided into upper die and lower die, and the upper mold passes through connector
It is fixed on plunger, the lower die is socketed with plunger, can be moved up and down with plunger；The shoulder strap is arranged on hydraulic pump, institute
It states hydraulic pump to pump for charged hydraulic, connects hydraulic oil pipe thereon, plunger is driven by hydraulic oil pipe fuel feeding.
Setting limited block at left and right sides of the upper mold, for limiting the movement of lower die.
The hydraulic pump is pumped for charged hydraulic.
A kind of firmly curved dog leg processing method of contact line, operation trolley is placed on rail, operating personnel climbs up hand push
Vehicle is backed on the body charged hydraulic pump using shoulder strap.Mould release is opened, and the contact line for having hard spot is placed in a mold, then
Mold 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 mold, 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 utility model has the advantage of：
The utility model provides power with rechargeable hydraulic pump, conveniently carries out in the wild whole curved；Hydraulic pump moves simultaneously
Power is powerful, and whole curved significant effect, working efficiency is greatly improved.
Description of the drawings
Fig. 1 is a kind of structure diagram of the firmly curved dog leg processing unit of contact line of the utility model.
Wherein：
Hydraulic pump 1, shoulder strap 2, hydraulic oil pipe 3, contact line 4, plunger 5, mold 6.
Upper mold 6.1, lower die 6.2, connector 6.3, limited block 6.4.
Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing embodiment.
As shown in Figure 1, the firmly curved dog leg processing unit of a kind of contact line in the present embodiment, including hydraulic pump 1, shoulder strap 2, liquid
Pressuring oil pipe 3, plunger 5 and mold 6, wherein mold are divided into upper mold 6.1 and lower die 6.2, and the upper mold 6.1 is solid by connector 6.3
It is scheduled on plunger 5, the lower die 6.2 is socketed with plunger 5, can be moved up and down with plunger 5, and 6.1 left and right sides of upper mold is set
Limited block 6.4 is put, for limiting the movement of lower die 6.2.
The shoulder strap 2 is arranged on hydraulic pump 1, and the hydraulic pump 1 is pumped for charged hydraulic, connects hydraulic oil pipe 3 thereon,
Plunger 5 is driven by 3 fuel feeding of hydraulic oil pipe.
A kind of firmly curved dog leg processing method of contact line, operation trolley is placed on rail, operating personnel climbs up hand push
Vehicle is backed on the body charged hydraulic pump 1 using shoulder strap 2.Mould release is opened, and the contact line 4 for having hard spot is placed in a mold,
Mold is closed again.After opening charged hydraulic 1 power switch of pump, hydraulic circuit driving stretches out plunger 5 upwards, plunger socket
Lower die 6.2 move up, slowly head on hard curved contact line, until it is bonded completely with upper mold 6.1, change is in line, complete
Into whole curved, one-pass molding, the time only needs several seconds, it is whole it is curved after the performance of contact line be not affected.
In addition to the implementation, the utility model has further included other embodiment, all to use equivalents or equivalent
The technical solution that alternative is formed, should all fall within the protection domain of the utility model claims.
