Description
Technical field
The invention belongs to railway abutment contact net corollary equipment, and in particular to a kind of intelligent multi-function contact net operation ladder
Car.
Background technology
Contact net operation ladder vehicle is power network construction and visual plant essential in maintenance.Contacted in different railways
Net height is different, occurs climb and fall, curve turnaround section in railway often, and the requirement for height to contact net operation ladder vehicle also has
Institute is different.The operation ladder vehicle of prior art is primarily present following problem：
1. being limited by rail standard, traditional tower wagon chassis is narrow, vehicle body is high, at the same plus often curve railway and on
Descending interval operation and traveling, operation ladder vehicle are easy to tumble, are damaged to workmen, influence construction speed.
2. traditional tower wagon needs at least four people to be helped below tower wagon, to prevent turning on one's side；And at wheel underbed body or
Set screw mandrel to withstand wheel at wheel, prevent tower wagon from being moved along track；At least four people is also required to during mobile tower wagon and helps close
Push dynamic, waste time and energy.
3. often dismounting is needed when tower wagon is used, to tackle the work requirements of different railway sections.Needed when such as using through
Track often is moved away from, is passed through with avoiding other vehicles, and traditional tower wagon is mostly an entirety, it is impossible to fast assembling-disassembling is carried out, is removed
Leave the right or normal track extremely difficult.
Therefore contact net operation ladder vehicle need to reach it is simple in construction, lightweight, be easy to often dismounting and transport, can be effective
Prevent from turning on one's side, meet the demand of different work height.
Chinese patent CN105150882A discloses a kind of anti-tipping, fast assemblying type contact net operation ladder vehicle, car ladder relative two
Side is trapezoidal, and base is provided with the retaining mechanism that anti-tower wagon is turned on one's side, and retaining mechanism is the normally closed locking linkage of push-press type, including is set
The pushing handrail on base is put, handrail both sides is pushed and is respectively connected with a connecting bar locking device, the dop of connecting bar locking device
Between base by the effect holding of extension spring with rail is normally closed engages, push/discharge pushing handrail so that link lock
The dop of tight device departs from/engaged base, job platform with rail and combines connection with car ladder respectively, and car ladder is by more than one section
Duan Zuhe connections, combination junction is provided with fast connector.
Anti-tipping complicated because tower wagon uses carbon steel material in the patent, height adjustable structure is also excessively bothered, weight
Amount is larger, can not still solve that simple in construction, weight is small, function is strong, easy to disassemble and transport technical problem.
Generally speaking, the defect that traditional anti-tipping device is present has：1. needing operating personnel manually operated, lose time；2.
The anti-tipping device of tradition can only be unilateral close to rail, realizes anti-down function, rail, some traditional anti-tipping devices can not be embraced completely exists
Embrace after rail, tower wagon is unable to self-locking, tower wagon energy self-locking and immovable, and all there is certain potential safety hazard.
The content of the invention
In view of the above-mentioned problems, the present invention is intended to provide a kind of intelligent, multi-functional, anti-tipping, simple in construction, weight it is small,
It is easy to dismount and transports, the contact net operation ladder vehicle of different height and width job requirements can be met.
The technical scheme of the present invention that solves the problems, such as is：A kind of intelligent multi-function contact net operation ladder vehicle, including chassis, peace
