Description
Technical field
What the present invention relates to is a kind of trackless trolley car collector bow, and particularly a kind of trackless trolley car two-wire powering type collector bow that has the spring damping tube belongs to the urban public transport field.
Background technology
The trackless trolley car that is used for the urban public transport transportation at present, low, the no exhaust emission of noise, starting and the fast characteristics of going up a slope are arranged, but because the existence of its built on stilts power supply contact gauze and roof trolley pole and current collection crawler shoe, make electric car can't surmount electric car, travel in as the view that current collection crawler shoe high jump lead accident easily causes traffic tie-up and influences the sky, street, city takes place; Adopt large-capacity battery or cond accumulation of energy, stopping the station area charging type trackless trolley car of fast charge can the built on stilts power supply contact of most of cancellation gauze, only retain one section special-purpose contact system of charging in the station district, but the such structure of trolley pole and groove shape current collection crawler shoe makes trackless trolley car will realize its automatic lifting and automatically line is networked very difficult reliably in the process that at every turn pulls in again, and the slide plate electric means of employing roof pantograph or collector bow, then automatic lifting networks to retrain to line and lacks, find by literature search, China Patent No. is: 00224010.6, name is called: pantograph, this utility model patent readme is " a kind of current collection device that is subjected to power taking stream in the electric locomotive from contact system that is installed in; by underframe; underframe; upper frame; bow; transmission device is formed, it is characterized in that: it also has a damper, this damper is installed between the lower arm rod and underframe of underframe, its advantage is that bow can be followed on contact system carries out apace, the following adjustment, remaining with contact wire during quasi high-speed or high-speed cruising at locomotive has certain mutual pressure, unlikely generation ' off-line ' phenomenon has guaranteed that locomotive is in quasi high-speed or normal during the high-speed cruising state, stable power supply." though this utility model can be used for the city railway vehicle of electric locomotive and other form; the built on stilts power supply contact gauze of railroad vehicle is solid conductor system; the bow top conduction slide plate of its pantograph or collector bow only can be subjected to electricity by single line, and the trackless trolley car double-circuit that can't satisfy the power supply contact wire and be two-conductor line system is subjected to electric requirement; So and the type pantograph or collector bow are whole charged because of single line is flowed, and only need and the roof insulation, the pantograph of trackless trolley car also needs the mutual insulating between two-wire, so such The Application of Technology scope is very limited.
Summary of the invention
The objective of the invention is to overcome deficiency of the prior art, a kind of trackless trolley car two-wire powering type collector bow that has the spring damping tube is provided, the pantograph or the collector bow that push up very long separation slide plate and insulation measures elimination prior art with its bow can only be subjected to stream can't accomplish the restriction that double-circuit is flowed simultaneously by single line, and the trackless trolley car trolley pole and the groove shape current collection crawler shoe that change other type, the difficulty that additional alignment device automatic lifting networks to line, make it can either double-circuit be subjected to simultaneously stream can controlled frequent lifting automatically line to be networked again, satisfy the station area charging type trackless trolley car liter bow that enters the station and network and flowed fast charge, requirement of falling bow leaving from station.
The present invention is achieved by the following technical solutions, the present invention includes: underframe, lower arm rod, pull bar, last armed lever, trammel beam, bow seat cross bar, cylinder, the spring damping tube, bow top cross bar, bow top conduction slide plate, bench insulator, insulation rod, collector head spring, travel switch, underframe, lower arm rod, pull bar, last armed lever, trammel beam, two samesing lanar four rod mechanisms have been constituted between the bow seat cross bar, bow top conduction slide plate forms two electric bodies that are subjected at the middle part by the insulation rod partition, and be fixed on the cross bar of bow top by bench insulator supporting, bow top cross bar and bow seat cross bar flexibly connect at the middle part, two ends connect by collector head spring, bow top cross bar can be swung together with the top of the bow on it conduction slide plate just to float, the lower end of cylinder and underframe flexibly connect, the piston rod mouth captive joint spring damping tube of cylinder, the other end of spring damping tube and lower arm rod flexibly connect, and travel switch is fixed on the spring damping tube; When cylinder when the spring damping tube promotes the lower arm rod swing, whole collector bow mechanism's holder flat bow headstock cross bar and the conduction slide plate lifting of bow top, after the bow top conduction slide plate of collector bow rose, the two-conductor line with contact system under the effect of spring damping tube elastic thrust kept closed contact.
The present invention has substantive distinguishing features and marked improvement, because the bow top conduction slide plate of the collector bow that bow top conduction slide plate is more used than electric locomotive and city railway vehicle is longer, and bow top conduction slide plate cuts off insulation in the middle part split becomes two electric bodies that are subjected to, therefore can contact two-conductor line, double-circuit is flowed simultaneously; The trolley pole and the groove shape current collection crawler shoe that change trackless trolley car are pantograph and collector bow form, and adopt long bow to push up the conduction skateboard, be used the trackless trolley car station district of the having widened the double-contact wires line-spacing special-purpose contact system that charges, make the bow top of collector bow flowed part travel under the low speed in the certain road scope in station district with trackless trolley car in automatic lifting line network conveniently do not have constraint, rise automatically to the network problem of difficulty of line thereby solved trolley pole and groove shape current collection crawler shoe during trackless trolley car travels; Bow top cross bar can swing together with the top of the bow on it conduction slide plate and just float, the structure that cooperates the spring damping tube, the double-contact wires that can adapt to gauze exists diff-H, road surface and vehicle-mounted variation and wind to carry under the situation, and collector bow also can keep the closed contact that bends and net; Use trackless trolley car of the present invention only when pulling in, to rise the bow charging that networks, need not built on stilts power supply contact gauze after leaving from station also can travel, therefore not only greatly increased flexible property, and can most ofly remove built on stilts power supply contact gauze.The present invention have vehicle gauze constraint less, the bow net contact performance is good, flowed that firm power is big, safe and reliable, the characteristics of the net that can network out under steam, is applicable to station area charging type trackless trolley car, as the current-collecting device of its roof.
